　　What is a mechanical keyboard and how does it work?

　　

　　Working Principle:

　　

　　Physical Mechanical Switch: The working principle of mechanical keyboard is to achieve key triggering and feedback through physical mechanical switches. Each key is equipped with an independent mechanical switch, which consists of a spring and a switch.

　　

　　Key Trigger: When the key is pressed, the spring is compressed and the switch is switched, triggering the action of the key. This physical triggering method makes the triggering of mechanical keyboards more reliable and direct.

　　

　　Triggering force and triggering point: Each mechanical switch has a specific triggering force and triggering point. This means that the user needs to press a certain force to trigger the switch, and at a certain point in the key travel, the switch will complete the triggering action. This design allows users to choose different types of switches according to their preferences and needs to get the best feel and feedback.

　　

　　Durability: Each mechanical switch has an estimated lifespan, and usually fails after hundreds of thousands or even millions of key presses. This makes mechanical keyboards more durable than other types of keyboards and the first choice for many professional users and gamers.

　　

　　In addition, mechanical keyboards have higher durability and reliability than other types of keyboards, such as membrane keyboards. Each mechanical switch usually has a long service life and usually fails after hundreds of thousands or even millions of keystrokes. Therefore, mechanical keyboards are often considered the first choice by professional users and gamers.

　　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).Therefore, Non standard hardware factory Only then will more and more pump owners cheer for it and spread the value and function of the brand. 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:

　　

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

　　

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

　　

　　2. Good mechanical properties. The strength of parts processed by cold heading (extrusion) method is much better than that of cutting because the metal fibers are not cut.

　　

　　3. 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 are 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 relatively 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 developed at home and abroad.

　　

　　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 alone is actually a composite processing method that has both cold heading and extrusion.

　　During the preparation and organization of the Paris Olympic Games in France, there were indeed riots such as workers’ strikes in Paris. Some workers involved in the construction of the Paris Olympic Games project demanded an increase in wages and benefits and confronted the government, and staged a battle of workers’ police in the streets of Paris. In addition, many illegal immigrants also took the opportunity to threaten the French government to give them legal residency status, or illegal immigrants will stop participating in the construction of the Paris Olympic Games. For this, the French government has had to compromise.

　　

　　Many foreign athletes saw the news of the riots in Paris, France, and felt worried about the security in Paris, France, so it came out that foreign athletes with private bodyguards went to Paris, France, these messages are not necessarily true, but also reflect the various practical problems during the Paris Games. There is also news that the Chinese sports team to France also brought private security teams, such as China’s Shenzhen Huanyu Brothers bodyguard company and other security service teams, which are said to be the security partners of the Chinese sports team participating in the Paris Olympic Games. But this information is hard to verify.

　　

　　As a highly civilized capitalist country, France’s performance during the Olympic Games has surprised many foreigners, and foreign athletes worry about their safety in Paris, not joking, indicating that there are many security risks in Paris, France. The French city of Paris, which is prone to strikes, demonstrations and vandalism of public facilities, is no longer what it used to be, and it is natural for foreign athletes to have safety concerns.

　　Is it better to have a multi-core cable or a single-core cable? The difference between single-core cables and multi-core cables. Power cables are generally divided into single-core, double-core and three-core cables. Among them, single-core cables refer to cables with only one conductor in one insulation layer, while double-core cables refer to cables with two conductors in one insulation layer. In fact, both have their advantages and disadvantages. For example, when the line of a single-core cable is long, when the control circuit with a large current is used or when it is laid in water, in order to prevent or reduce the middle connector, or when single-core cables have better comprehensive safety engineering than multi-core cables, single-core cables can be used.Through bit by bit efforts, let multicore cable price Our market share is getting higher and higher, and the return on investment is also rising steadily. https://www.linkcablecn.com

　　

　　Is it better to have a multi-core cable or a single-core cable?

　　

　　1. From the current point of view, the current passing through a multi-core cable with the same cross-sectional area is relatively larger than that of a single-core cable, and the load is large.

　　

　　2. From the perspective of power loss, the two ends of the single-core cableare directly grounded, and the metal shielding layer of the cable may also generate circulating current that can reach the current carrying capacity of the cable, which wastes power and forms loss. Multi-core cables are generally three-core cables, because during the operation of the cable, the sum of the currents flowing through the three cores is zero, and there is basically no induced voltage at both ends of the cable metal shielding layer.

　　

　　3. From the perspective of cost, among the wires of the same cross-sectional area, the cost of single-core cables is cheaper than that of multi-core cables, and multi-core cables are slightly more expensive.

　　

　　4. From the perspective of installation, single-core cables appear harder when passing through pipes, while multi-core cables are softer and easier to wire.

　　The difference between single-core cables and multi-core cables

　　

　　2-core cables: When the neutral line of 1kv and below power supplies is directly grounded, the number of cable cores of the single-phase control circuit should be 2-core cables when the maintenance line and the neutral point share the same conductor. For control circuits that can be powered by DC, 2-core cables should be used.

　　

　　3-core cable: When the neutral line of 1kv and below power supply is directly grounded, the number of cable cores of the single-phase power control circuit is: When the protection line and neutral point are separate, it is advisable to use a 3-core cable.

　　

　　4-core cable: 1kv and below 4-core cable (3+1 cable), in which the fourth core is used as a grounding protection, and also carries the unbalanced current and short-circuit capacity of the power supply system. (To learn more about cable technology, please click here, a lot of dry goods are waiting for you) Its size is determined by the unbalanced current and short-circuit capacity, but generally cannot be less than 1/2 of the phase line.

　　

　　5-core cable: 1kv and below three-phase four-wire distribution room system, some electrical equipment distribution lines with higher safety requirements, and some communication centers and automation equipment that must ensure power safety and anti-interference grounding, it is advisable to use 5 copper core cable TN-C distribution room system, so that the protection line (PE line) and neutral point (PN line) are independent, and the cable core section is generally 3 large and 2 small or 4 large and 1 small or 5 large.

　　

　　Multicore Flexible Cable supplier.jpg

　　

　　The difference between 4-core cable and 3+1 core cable: 1kv and below three-phase four-wire distribution room system, when the protection line and neutral point share the same conductor, 4-core cable should be used, and the method of 3-core cable plus single-core cable to form a circuit cannot be used, or even the method of directly using the metal sheath or armored cable layer of 3-core cable as the neutral point. Otherwise, when the 3-phase current is unbalanced, it is equivalent to the operation of a single-core cable, which is easy to cause DC interference.

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion is an extrusion deformation of larger workpieces and has a wide range of uses.period non-standard fasteners price Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. https://jieruifasteners.com/

　　

　　1. What is cold extrusion

　　

　　Cold extrusion is a processing method in which a metal blank is placed in a cold extrusion die cavity and, at room temperature, a punch fixed on the press is used to apply pressure to the blank to cause the metal blank to undergo plastic deformation to produce parts. Obviously, cold extrusion processing relies on the die to control the flow of metal and relies on the large-scale transfer of metal volume to form parts. In terms of extrusion equipment, my country has the ability to design and manufacture extrusion presses of various tonnages. In addition to using general mechanical presses, hydraulic presses, and cold extrusion presses, friction presses and high-speed and high-energy equipment have also been successfully used for cold extrusion production.

　　

　　At present, cold extrusion technology has been widely used in industrial sectors such as fasteners, machinery, instruments, electrical appliances, light industry, aerospace, shipbuilding, and military industry, and has become one of the indispensable and important processing methods in metal plastic volume forming technology. With the advancement of science and technology and the continuous improvement of product technical requirements in the automobile, motorcycle, household appliances and other industries, cold extrusion production technology has gradually become the development direction of refined production of small and medium-sized forgings.

　　

　　

　　2. What is cold heading

　　

　　Cold heading is one of the new processes of metal pressure processing with little or no cutting. It is a processing method that uses the plastic deformation of metal under the action of external force, and with the help of a mold, the metal volume is redistributed and transferred to form the required parts or blanks. The cold heading process is most suitable for the production of non standard fasteners such as bolts, screws, nuts, rivets, and pins. The commonly used equipment for cold heading is a dedicated cold heading machine. If the production volume is not too large, it can also be replaced by a crank press or a friction press.

　　

　　Cold heading technology has high productivity, good product quality, and greatly reduces material consumption, reduces production costs, and improves working conditions. Therefore, it is more and more widely used in mechanical manufacturing, especially in the production of standard fasteners. Among them, the most representative products produced by multi-station cold heading machines are bolts, screws and nuts.

　　

　　3. Are cold heading and cold extrusion the same thing?

　　

　　Cold heading and cold extrusion are basically deformation processes under the same conditions, but they are different in operation. Cold heading is a forging deformation of smaller workpieces and is often used in the fastener industry. Cold extrusion, on the other hand, is an extrusion deformation of larger workpieces and is widely used; cold heading is equivalent to a branch of cold extrusion. Simply put, in the process of making bolts, hexagonal head forming is cold heading, and rod diameter reduction is cold extrusion (positive extrusion). Non-cut hexagonal flange bolts (multi-station forming) have both cold heading and cold extrusion. The front shaping of hexagonal nuts is only cold heading, and the hole extrusion in the back process is cold extrusion (positive and negative extrusion).
