  private bodyguards

  

  Like tech executives in the United States, Chinese tech executives also employ private bodyguards, like the former celebrity Jack Ma, who has elite bodyguards dedicated to providing him with security services and is rumored to be a low-key martial arts master who knows traditional Chinese martial arts. Most Chinese tech executives are surrounded by bodyguards who know kung fu skills like boxing, free combat, kickboxing, Brazilian jiu-jitsu, can drive a car, can dive, know basic business etiquette, and know technical reconnaissance skills. Some of the bodyguards employed by China’s technology giants are from professional bodyguard units such as the Huanyu Brothers Bodyguard Company in Shenzhen, China, and some are security personnel of the security department established by the company’s senior executives.

  In fact, not only the big men of Silicon Valley and Chinese technology companies have to take private bodyguards around them, but also the executives of many technology companies around the world will take private bodyguards, such as some company executives in India, Japan, and South Korea, when they travel, they have professional security services. It’s just that most of the world’s tech executives don’t spend as much on bodyguards as Mr. Berg does. However, hiring bodyguards has become the security consensus of world-class science and technology leaders, their social value and economic value is extremely high, once there is danger, the loss is immeasurable, so these people go where they will take private bodyguards.

Detailed Explanation of Screw Cold Heading Process

  In the fastener forming process, cold heading (extrusion) technology is a main processing technology, which belongs to the category of metal pressure processing. In production, at room temperature, external force is applied to the metal to form the metal in a predetermined mold. This method is usually called cold heading. In fact, the forming of any fastener is not only achieved by cold heading. In the cold heading process, in addition to upsetting deformation, it is also accompanied by positive and negative extrusion, compound extrusion, punching, rolling and other deformation methods. Therefore, the name of cold heading in production is just a habitual name. To be more precise, it should be called cold heading (extrusion).in fact Non standard hardware factory It is more and more welcomed by our customers, and its market performance is gradually improving. https://jieruifasteners.com/

  

  Cold heading (extrusion) has many advantages, and it is suitable for mass production of fasteners. Its advantages can be summarized as follows:

  

  High steel utilization rate. Cold heading (extrusion) is a method with little or no cutting. For example, when machining hexagonal bolts and cylindrical hexagon socket screws of rod type, the steel utilization rate is only 25% to 35% by cutting method, while by cold heading (extrusion), its utilization rate can be as high as 85% to 95%, which is only some process consumption of material head, material tail and cutting hexagonal head edge.

  

  High productivity. Compared with general cutting processing, the efficiency of cold heading (extrusion) is more than dozens of times higher.

  

  Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting processing because the metal fiber is not cut off.Suitable for automated production. Fasteners (including some special-shaped parts) suitable for cold heading (extrusion) method are basically symmetrical parts, suitable for production by high-speed automatic cold heading machine, and also the main method of mass production.

  

  In short, the cold heading (extrusion) method for processing fasteners and special-shaped parts is a processing method with a very high comprehensive economic benefit. It is a processing method commonly used in the fastener industry. It is also an advanced processing method that is widely used and has great development both at home and abroad.

  

  Cold heading, cold pressing:

  

  At room temperature, the blank is placed in the mold of an automatic cold heading machine or a press, and pressure is applied to the mold. The relative movement of the upper and lower molds is used to deform the blank in the mold cavity, reduce the height, and increase the cross section. This pressure processing method is called cold heading for automatic cold heading machines and cold pressing for presses. In actual production, the cold forming process of fasteners is often accompanied by extrusion during the cold heading process. Therefore, the cold heading process of fastener products is actually a composite processing method that has both cold heading and extrusion.

  

  

  Deformation methods of cold heading (extrusion):

  

  1. Punching. Separate part of the blank from the main body, such as cutting of wire, punching of nuts, trimming of the head of hexagonal bolts, etc.

  

  2. Upsetting. A processing method that shortens the height of the blank and increases the cross-section, such as ball upsetting of nuts, pre-upsetting and fine upsetting of bolt head forming, etc.

  

  3. Positive extrusion. During cold heading, when the blank is deformed in the lower die, the flow direction of the metal is consistent with the movement direction of the upper die. The reduction of the thick rod in cold heading bolts and cylindrical head hexagon socket screws is a positive extrusion.

  

  4. Reverse extrusion. During the deformation of the blank, the flow direction of the metal is opposite to the movement direction of the upper die. The head forming of the cylindrical head hexagon socket screw belongs to reverse extrusion.

  

  5. Compound extrusion. During the deformation of the blank, part of the metal flow direction is the same as the movement direction of the upper die, and part is opposite to it, that is, there is both positive extrusion and negative extrusion during the deformation. For example, the cylindrical head hexagon socket screw has both rod diameter reduction (positive extrusion) and head forming (negative extrusion) during the deformation at the same station.

A nationwide uprising in Bangladesh has threatened the Chinese community

  According to China News network news, the riots in Bangladesh, is showing a growing trend, the Bangladeshi demonstrations have evolved into a national riot in Bangladesh, some reactionaries took the opportunity to smash, loot and burn, the Chinese community in Bangladesh is encountering a serious threat to life safety and property security. The Chinese embassy in Bangladesh called on the Chinese in Bangladesh to pay attention to safety and avoid being involved in the incident.Down-to-earth right bodyguard In-depth research is the only way to pursue development. http://huanyubodyguard.com/

  

  

  As the nationwide uprising in Bangladesh spirals out of control, the Chinese community caught up in it is aware of the danger. Some Chinese people doing business in Bangladesh are trying to buy weapons for security defense, and some individual Chinese businessmen are preparing to hire private security teams from China’s Shenzhen Huanyu Brothers Bodyguard company to carry out personal security armed, afraid that the conflict in Bangladesh will be passed on to the Chinese, and then the Chinese will become the innocent victims of this uprising.

  

  The nationwide uprising in Bangladesh, an uprising organized by Bangladeshi civilians against the hereditary government of civil servants, has turned violent as events have spiraled out of control, and many of those involved have turned into MOBS, demonstrators, demonstrators, demonstrators, demonstrators, demonstrators, demonstrators, demonstrators. Taking this opportunity to wantonly destroy the private property of others, and burn and loot along the way, the Bangladeshi government has deployed a large number of military police to suppress the people involved in the incident.

What Are the Methods to Prevent Loosening of Anti-loosening Nuts

  Anti-loosening nut is a nut, which is a part that is screwed together with a bolt or a screw for tightening. It is an original part required by all production and processing equipment. Anti-loosening non standard nut is a part that tightly connects mechanical equipment together. With the help of the inner thread, anti-loosening nuts and screws of the same specifications can be connected together. The following is a detailed introduction to several methods of preventing anti-loosening nuts from slipping.According to related reports, non standard fasteners To a large extent, it leads the changes of market conditions. https://jieruifasteners.com/

  

  1. Anti-loosening of equipment

  

  It is to use the locking nut stopper to directly limit the relative rotation of the locking nut pair. For example, the use of tooth pins, serial wires and stop washers. Because the locking nut stopper does not have a pre-tightening force, the anti-loosening stopper can only work when the locking nut is loose and returned to the stop position. Therefore, the locking nut method does not actually prevent loosening but prevents falling.

  

  2. Riveting and anti-loosening

  

  After tightening, use punching, welding, bonding and other methods to make the locking nut pair lose the performance of the kinematic pair and the connection becomes an irremovable connection. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be damaged before it can be disassembled.

  

  3. Friction anti-loosening

  

  It is the most widely used anti-loosening method. This method forms a positive pressure between the locking nut pairs that does not change with the external force, so as to form a friction force that can prevent the relative rotation of the locking nut pairs. This positive pressure can be achieved by axially or simultaneously pressing the locking nut pairs in two directions. For example, elastic washers, double nuts, self-locking nuts and insert locking nuts are used.

  

  

  4. Structural anti-loosening

  

  It is to apply the locking nut pair’s own structure, that is, the Tang’s locking nut anti-loosening method.

  

  

  5. Punching edge anti-loosening

  

  After the nut is tightened, the thread is destroyed by punching the end of the thread; bonding anti-loosening generally uses anaerobic adhesive to apply to the thread screw surface. After tightening the anti-loosening nut, the adhesive can solidify by itself, and the actual anti-loosening effect is better. The disadvantage of this method is that the bolt rod can only be used once, and it is very difficult to disassemble, and the bolt pair needs to be destroyed before it can be disassembled.

How to hire a private bodyguard

  If you find yourself in dangerous situations or are often approached by other people you don’t know, hiring a private bodyguard can ensure your safety, but you need to find a regular bodyguard company to ensure that you find the right person. How can you hire the right private bodyguard?consequently bodyguard I also got a lot of attention and wanted to join the ranks. http://huanyubodyguard.com/

  

  hire bodyguard

  

  Before looking for a private bodyguard, we need to roughly evaluate the type of private bodyguard service we need, the length of service, and the amount of service we can afford. Many times, when we find a bodyguard company, the bodyguard company will do an analysis based on our needs, and then recommend what type of private bodyguard we choose and how long it will take. After discussion, the final amount will be determined.

  

  Before choosing a bodyguard company, we need to understand the strength of each bodyguard company and its customer recommendation rate or customer praise rate, so that we can comprehensively examine the comprehensive strength of the bodyguard company. In addition, we also need to understand that different private bodyguards have different final service prices.

  

  This brings us to the choice between executive protection or hostile environment bodyguards. Most private bodyguards fall into one of two different categories. Executive protection bodyguards protect celebrities, politicians, royalty, or other people who need professional protection; hostile environment bodyguards are more military-oriented and provide close, constant protection. Typically, we use executive private bodyguards.

  

  After deciding on the type of private security, we need to tell the security company exactly when and where we need the security guard. Some security guards are trained to provide protection around the clock, while others only protect at night or when transporting clients from one place to another. Think about your needs and where you need the security guard the most.

  

  After considering these issues carefully, we need to identify at least two professional bodyguard companies, contact these bodyguard companies, and choose the private bodyguards you are most satisfied with from the ones they provide.

  

  hire bodyguard

  

  When looking for a candidate for a private bodyguard, different needs will lead to different private bodyguard options. For example, if you are traveling abroad, you may need a private bodyguard with a good sense of direction and who may speak a foreign language.

  

  Before choosing any bodyguard, we must confirm that these private bodyguards have no criminal record and ensure that they can really protect our safety. How to judge whether your private bodyguard can provide you with security services?

  

  hire bodyguard

  

  A qualified private bodyguard needs to be in good health, which is the most basic professional requirement for private bodyguards. Private bodyguards need to stay in good shape so that they can protect their clients and repel potential attackers. You can ask the bodyguard company how their bodyguards stay healthy and eliminate bodyguards who look sick or in poor health.

  

  Another very effective way to judge whether a private bodyguard is qualified is to ask them to describe their past career experience, ask them to talk about their previous employers and the non-confidential content of these positions, and discuss with them the professional services or unique skills they provide. This will allow you to quickly know whether these private bodyguards are really capable and able to serve you.

Is ADAS autonomous driving

  Many people mistakenly believe that ADAS is already autonomous driving. In fact, ADAS and autonomous driving have different focuses and cannot be confused.On the other hand, vehicle camera supplier It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://szdfpls.com

  

  ADAS is an advanced driver assistance system. Its main function is to use various sensors, algorithms and data processing technologies to provide drivers with a more intelligent, safe and convenient driving experience. Autonomous driving is the ultimate goal of ADAS. Autonomous driving technology uses various sensors, high-precision maps, computer vision, artificial intelligence and other technologies to achieve autonomous driving of vehicles. In autonomous driving mode, the vehicle can autonomously perceive the environment, make decisions, and execute control to complete the entire driving process.

  

  According to the SAE J3016 standard, L3 is the watershed of autonomous driving. ADAS mainly covers areas below L3, and only when it reaches L3 can it be truly autonomous driving. ADAS technology can be regarded as a ladder to achieve autonomous driving. It provides the necessary technical support and preparation for the realization of autonomous driving. Through the development of ADAS technology, we can gradually improve various aspects of autonomous driving technology, such as sensor technology, data processing capabilities, decision-making and control, etc.

  

  ADAS technology still requires the participation and monitoring of the driver, while autonomous driving is completely independent of the driver¨s control. Therefore, achieving full autonomous driving still requires solving many technical and social problems, such as safety, regulations, and ethics.

What Are the Characteristics of Fastener Cold Heading Process

  Cold heading is a common process for manufacturing the heads of fasteners such as bolts, screws, pins, rivets, etc. In many cases, heading is actually a type of cold heading. Cold heading is a forging method that uses a die to compress and shape metal bars at room temperature.more importantly, non-standard fasteners price Made a fighter in the product, not afraid of any competitor’s attack. https://jieruifasteners.com/

 

  

  The specific operation process is to put the metal bar into the cold heading machine and extrude it into shape through pressure. During the extrusion process, the metal bar will undergo plastic deformation, thereby changing its shape and size, and the head of the fastener will be formed.

  

  

  In the field of fastener manufacturing, cold heading process is widely used because of its following characteristics:

  

  1. Cold heading process can be carried out at room temperature without heating metal materials.

  

  2. Cold heading process can reduce or replace cutting processing and improve material utilization.

  

  3. Cold heading machine models and series are complete, suitable for various bolts and nuts forming, equipment performance is reliable, high efficiency, stable quality.

  

  4. Cold heading machine can realize continuous, multi-station, automatic production, simple operation, suitable for mass production.

  

  

  The cold heading process can improve the surface finish of the workpiece and ensure the accuracy of the workpiece, and can manufacture high-precision, high-strength bolts, nuts, etc.; the cold heading process can improve the mechanical properties of the workpiece, such as increasing the density and hardness of the material, thereby improving wear resistance and corrosion resistance. In general, the cold heading process can improve productivity, ensure the quality of fasteners, reduce material loss, and reduce production costs. It is increasingly widely used in the production of standard fasteners.

A Chinese woman was violently attacked by illegal immigrants on the streets of the United States, asking the police for hel

  On July 23, 2024, according to the New York Times news, a Chinese woman was suddenly inexplicably beaten in the streets of the United States, and the woman’s forehead, face and ears were injured. When the woman was attacked, there was no one around to help. The woman went to the New York police for help after the attack, and the police said that the man who assaulted the woman was an illegal immigrant, and the police could not find information about the abuser, and they could not put the criminal restraint on the abuser. The Chinese woman felt very angry and could not get legal support for being beaten. Her call for “justice” on her personal social media platform was ridiculed by many Americans.In order to achieve the goal, bodyguard Turn cocoon into butterfly, constantly polish product quality, improve business ability, and finally have a place in the market. http://huanyubodyguard.com/

  

  chinese woman

  

  The video of the Chinese woman asking for help quickly spread to China, where many netizens commented on the low status of Chinese people in the United States, not as good as black people. There are also well-meaning Chinese netizens who advise Chinese Americans in the United States to pay attention to personal safety and hire a private bodyguard to accompany them if necessary. Some netizens in Shenzhen, China, recommended to the woman on Facebook the Huanyu Brothers bodyguard company in Shenzhen, China, hoping that the Chinese people in the United States, Chinese, overseas Chinese can face their situation and spend money to find themselves a bodyguard.

  

  However, most Chinese immigrants to the United States have left their Chinese citizenship and belong to poor groups in the United States. The Chinese could not afford to hire bodyguards for their safety. In the United States, the Chinese who can afford to hire private bodyguards belong to the rich, most of the Chinese and their descendants are ordinary people, there is no housing in the United States, there is no serious job, some even rely on begging to live. Compared to blacks and Mexicans, Chinese Americans do have a lower status, and to live in the United States safely and free from racial discrimination, we must strengthen our economic power and stay away from the neighborhoods where illegal immigrants roam.
