　　Shielded cable is a transmission line that uses a metal mesh braided layer to wrap the signal line. The braided layer is generally red copper or tinned copper. Shielded cable is a wire with a metal braided shell specially used to reduce the impact of external electromagnetic fields on power or communication lines. This shielded cable also has the function of preventing the line from radiating electromagnetic energy outward. The shielding layer needs to be grounded, and external interference signals can be introduced into the ground by this layer.Therefore, this is the choice custom multicore cable The reason, there is no denying its positive impact. https://www.linkcablecn.com

　　The shielding layer of the shielded wire is mainly made of non-magnetic materials such as copper and aluminum, and the thickness is very thin, which is much smaller than the skin depth of the metal material at the frequency of use (the so-called skin effect refers to the distribution of current in the conductor cross section tending to the conductor surface with the increase of frequency. The higher the frequency, the smaller the skin depth, that is, the higher the frequency, the weaker the penetration ability of electromagnetic waves). The effect of the shielding layer is not mainly due to the reflection and absorption of the electric field and magnetic field by the metal body itself, but due to the grounding of the shielding layer. Different grounding forms will directly affect the shielding effect.

　　Shielding is divided into active shielding and passive shielding. The purpose of active shielding is to prevent the noise source from radiating outward, which is to shield the noise source; the purpose of passive shielding is to prevent sensitive equipment from being interfered by the noise source, which is to shield sensitive equipment. The shielding layer of the shielded cable is not allowed to be grounded at multiple points, because different grounding points are always different, and there is a potential difference between each point. If multiple points are grounded, current will be formed in the shielding layer, which will not only fail to play a shielding role, but also introduce interference. Especially in occasions where frequency converters are used frequently, the interference contains various high-order harmonic components, which have a greater impact and should be paid special attention to.

　　The shielded wiring system originated in Europe. It adds a metal shielding layer to the outside of the ordinary unshielded wiring system, and uses the reflection, absorption and skin effect of the metal shielding layer to achieve the function of preventing electromagnetic interference and electromagnetic radiation. The shielding system comprehensively utilizes the balance principle of twisted pair cables and the shielding effect of the shielding layer, so it has very good electromagnetic compatibility (EMC) characteristics. Electromagnetic compatibility (EMC) refers to the ability of electronic equipment or network systems to resist electromagnetic interference to a certain extent, and at the same time cannot generate excessive electromagnetic radiation. In other words, the device or network system is required to be able to work normally in a relatively harsh electromagnetic environment, and at the same time, it cannot radiate excessive electromagnetic waves to interfere with the normal operation of other surrounding devices and networks.

　　The shielding principle of shielded wire is different from the balanced offset principle of twisted pair. Shielded cable is to add one or two layers of aluminum foil on the outside of the four pairs of twisted pair wires, and use the reflection, absorption and skin effect of metal on electromagnetic waves to effectively prevent external electromagnetic interference from entering the cable, and also prevent the internal signal from radiating out and interfering with the work of other devices.

　　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.Mentioned in the article Non standard hardware factory Born with strong vitality, you can turn a cocoon into a butterfly and become the best yourself after wind and rain. 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.

　　The Chinese demonstration in New York State, the United States, is an event organized by the Chinese in New York State against the United States government, in order to defend the security rights and interests of the Chinese in the Chinese area, the Chinese launched a protest to the New York government, feeling that the United States to build a homeless area in the Chinese area of New York, will threaten the safety of the Chinese in the Chinese area. Because the vagabonds that the vagabonds take in, the vagabonds of the world who steal and rob for a living, are mostly drug addicts. But the resistance of the Chinese may be ineffective, because the New York State government will not listen to the opinions of the Chinese, the Chinese in this state want to defend their survival and security rights, they need to find another way, there are New York Chinese ready to cooperate with China Shenzhen Huanyu Brothers bodyguard company, hire the bodyguard in the Chinese bodyguard company to protect the security, if the homeless in New York State officially opened the construction. The Chinese in New York State are likely to face a number of security challenges.

　　new york clashes

　　Some media believe that the US state of New York has chosen to build homeless shelters in Chinese areas, which is to bully Chinese Americans, and the local government does not build homeless shelters in places where Americans are concentrated, but to build homeless shelters in Chinese areas, which is to condone the security intrusion of homeless people on Chinese people in Chinese areas. It is not easy for Chinese Americans to obtain the same rights and interests as American citizens in countries such as the United States. If homeless shelters are really built in the Chinese area of New York State, the residential safety, personal safety and property safety of a large number of Chinese Americans will be lost.

　　On the one hand, ADAS-related codes need to follow the software development requirements of the functional safety standard ISO 26262, use strict coding specifications to write coding, and perform complete functional safety processes during the development process, such as requirements management and code unit testing. In advanced ADAS, safety needs to be achieved through redundancy and monitoring mechanisms in algorithms and system architectures, such as two independent neural network modules that monitor each other, and a safety monitor that continuously detects the status. This can avoid systematic errors or random failures in the algorithm design process.Industry experts have said that, 360 panoramic camera factory It is very possible to develop and expand, which can be well seen from its previous data reports. https://szdfpls.com

　　On the other hand, for algorithm defects that cannot be fully foreseen in the ADAS system, such as insufficient performance, a large number of test cases are needed to cover various usage scenarios to simulate and test the entire system.

　　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.After that, non standard fasteners Not afraid of the future, dare to fight and fight, and won applause again and again in the market. 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).

　　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.For the current market situation, bodyguard It has a very advantageous development prospect and an extremely superior ecological environment. 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.

　　Since the riots in Bangladesh, many Chinese have expressed security concerns, and many are looking for ways to protect themselves and their families from being caught up in the unrest and becoming an outlet for the mob’s anger.
