Summary of information:We have more than ten years of experience in screw industry production, the main products are: wing nuts, trimmed hex bo...

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to overcome the above shortcomings and provide a limit screw. The technical scheme of Guangdong Yueluo Hardware Industry Co., Ltd. is realized in the following way. Its structure is composed of screws, hexagonal copper posts and limit necks. The left end of the limit neck is open, the hexagonal copper column is communicated with the inside of the limit neck, and the inside is provided with screw threads. The design length of the screw thread in the hexagonal copper column is 1/3-2/3 of its own length. The advantages of Guangdong Yueluo Hardware Industry Co., Ltd. are (12), which can effectively prevent the problem of poor memory contact caused by the increase in the deformation of the motherboard due to the warping and deformation of the motherboard during installation and fixing, and can effectively control the deformation. effect.

Most of the capacitors on the market have two pins, which are the connection terminals of the positive and negative electrodes of the capacitor. At present, there is a big hidden danger in these capacitors, that is, the connection between the pins and the core inside the capacitor is basically a stick-on connection. When the capacitor is working, the internal temperature rises rapidly, and the stick-type connection is unstable after being heated, and it is easy to detach Or loose.

A nut is a nut, a part that is screwed together with a bolt or screw for fastening. A component that must be used in all production and manufacturing machinery is divided into carbon steel, stainless steel, non-ferrous metals (such as copper), etc. several types.

Iron two combination screws can be sucked up with magnets, but stainless steel two combination screws are difficult to be sucked up. Environmentally friendly three-combination screws and non-environmentally friendly ones are invisible to the naked eye and require mechanical testing. It cannot be judged with the naked eye and out of thin air. The specifications of the two combination screws need to be determined by the national standard. The salt spray of the two combination screws needs to be measured with a salt spray machine for how many hours.

The positioning pin is a pin designed to accurately position the two adjacent parts of the mold in a mold composed of two or more parts. It can be seen that the positioning pin plays a positioning role, and the mold must be accurately synchronized when it is closed. product, and the positioning pin can make the upper and lower molds play a role in accurate positioning. In the mold design and manufacture of Yueluo, the positioning pin is one of the most common parts. Since it is only used for positioning between parts, few people will pay too much attention to it. In the cold stamping process of Yueluo, the dimensional accuracy of the blanking parts depends on the size of the working part of the punch and the concave die, and the dimensional difference between them constitutes the blanking die gap. Gap is an important process parameter for die design, and its size has a great influence on the quality of the section of the blanking part, the blanking force, and the life of the die. If the gap is too large, punching burrs will appear in punching; if the gap is too small, secondary cracks will occur in the section and extrusion burrs will appear, which will make the quality of the section after punching unsatisfactory, and a reasonable gap will not only help the punching section. The improvement of quality also contributes to the improvement of the lifespan of the 5-pack.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: through-hole star handle screws and nuts, butt screw rivets, lengthened ring screws, thin small flat washers and other products, we can provide you with products suitable for you fastener solutions.
