　　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).To some extent, Non standard hardware factory Our development has surpassed many peer businesses, but it has never stopped moving forward. 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.

　　There are many steps in makeup, and the makeup tools used in different steps are different. For example, when painting eye shadow, eye shadow brush will be used, and when concealing, concealer brush will be used. So, can the eye shadow brush be used as a concealer? Concealer brush is harder than eye shadow brush, and the brush head is smaller. Concealer is generally paste, but eye shadow brush is not suitable. Let’s learn more about the difference between concealer brush and eye shadow brush.Therefore, this is the choice makeup brush set The reason, there is no denying its positive impact. https://lsmakeupbrush.com

　　First, can the eye shadow brush be used as a concealer brush?

　　The eye shadow brush can’t act as a concealer. The concealer brush is to dip a proper amount of cosmetics, that is, concealer liquid foundation, etc., and then smudge the edge of the concealer, remember to use it a few times. The material of eye shadow brush is not suitable for concealer.

　　Eyeshadow brushes can be roughly divided into five types according to the size of the brush head. Generally speaking, the color brushed by the big brush head is relatively light, which is suitable for a large area of eye socket, and the middle brush head is used to brush the middle color. People with deep double eyelids can get eye shadow on the wide side of the brush. Eyeshadow brush with pencil brush head is generally a necessary tool to draw a gradual feeling at the end of the eye. Small flat brush with long hair is mainly used to enhance the effect of key colors.

　　Second, the difference between concealer brush and eye shadow brush

　　1. In terms of softness and hardness, concealer brushes are generally hard, while eye shadow brushes are softer; In terms of brush head area, concealer brush head is smaller, and eye shadow brush head is bigger; In terms of usage, if you choose a concealer brush, you should adopt a point painting method, and if you choose an eye shadow brush, you should adopt a horizontal painting method.

　　2, concealer brush is mainly used to cover a small area of the face, emphasizing accuracy, so the concealer brush is hard, which is more convenient to apply. The eye shadow brush is used to apply eye shadow, which needs to be applied repeatedly on the eyelids. If the brush head is too hard, it will hurt delicate skin, so the bristles of the eye shadow brush are particularly soft.

　　3. When you need to retouch your makeup, you can dip a small amount of liquid foundation and concealer with a concealer brush and gently apply it to acne marks and other parts. In order to make the concealer and the base makeup blend together better, you can gently wipe the border with a cotton swab, so that the concealer can smudge better and blur the dividing line.

　　4. The brush head of the eye shadow brush is generally larger than the concealer brush, but there are many kinds of eye shadow brushes, and each eye shadow brush is used to apply different parts. Eyeshadow brushes with large area and flat shape are generally used as a base, which can ensure that the edges and corners are taken care of. You can dip it in white or beige, and then apply it across the entire eyelid. A small flat eye shadow brush is generally used to highlight the main color, and is usually used to smear the middle of the eyelid. Eyeshadow brushes with small area and sharp shape are generally used to repair or outline.

　　5. Concealer brush and eye shadow brush have their own strengths. If you want to create a perfect makeup, it is best to buy them together. And whether it is a concealer brush or an eye shadow brush, remember to clean it in time after use, so as to ensure that you still have a clean beauty brush next time.

　　As interconnect technologies, InfiniBand and Ethernet are different, and it is difficult to say which one is better. They continue to develop in different application fields and become two indispensable interconnect technologies in the network world.In today’s market background, 400g aoc cable Still maintain a strong sales data, and constantly beat the competitors in front of us. https://www.3coptics.com/

　　InfiniBand vs. Ethernet: What are they?

　　InfiniBand Networking

　　From a design perspective, there are big differences between InfiniBand and Ethernet. As a network interconnection technology, InfiniBand is widely used in supercomputer clusters due to its high reliability, low latency, and high bandwidth. In addition, with the development of high-performance computing, InfiniBand has also become an ideal choice for GPU server network interconnection technology.

　　To achieve the original data transmission rate of 10Gbit/s on 4X cables, the InfiniBand standard allows the transmission of single data rate (SDR) signals at a basic rate of 2.5Gbit/s on each channel. A single channel can be expanded to 5Gbit/s and 10Gbit/s respectively, and the maximum data transmission rate is 40Gbit/s on 4X cables and 120Gbit/s on 12X cables, thus enabling InfiniBand networks to have double data rate (DDR) and quadruple data rate (QDR) signals.

　　InfiniBand

　　Ethernet Network

　　Since its introduction on September 30, 1980, the Ethernet standard has become a widely used communication protocol in local area networks. Unlike InfiniBand, Ethernet was designed with the following goals in mind: How to easily transmit information between multiple systems? It is a typical network designed for distribution and compatibility. Traditional Ethernet mainly uses TCP/IP to build networks and gradually develops into RoCE.

　　Generally speaking, Ethernet networks are mainly used to connect multiple computers or other devices (such as printers, scanners, etc.) to a local area network. It can connect an Ethernet network to a wired network through fiber optic cables, or it can connect an Ethernet network to a wireless network through wireless networking technology. Fast Ethernet, Gigabit Ethernet, 10 Gigabit Ethernet, and Switched Ethernet are all major Ethernet types.

　　Ethernet

　　InfiniBand vs. Ethernet: What are the differences between them?

　　Cluster data transmission bottlenecks in high-performance computing scenarios are the original design target of InfiniBand, and it has become an interconnection standard that meets the requirements of the times. Therefore, there are many differences between InfiniBand and Ethernet in terms of bandwidth, latency, network reliability, network technology, and application scenarios.

　　Bandwidth

　　Since the advent of InfiniBand, the development speed of InfiniBand network has been faster than Ethernet. The main reason is that InfiniBand is used for interconnection between servers in high-performance computing and to reduce CPU load. However, Ethernet is more oriented to the interconnection of terminal devices and does not require too much bandwidth.

　　For high-speed network traffic exceeding 10G, if all data packets need to be unpacked, a lot of resources will be consumed. The first generation of SDR InfiniBand runs at 10Gbps, which not only increases data transmission bandwidth and reduces CPU load, but also allows high-speed network transmission to offload CPU and increase network utilization.
