What is the tolerance range of precision screws?
[In a preferred example of Guangdong Yueluo Hardware Industry Co., Ltd., the cone includes a large diameter end and a small diameter end, the diameter of the large diameter end is the same as the diameter of the inner hole in the middle of the nail body, and the diameter of the small diameter end is Two-thirds of the diameter of the large diameter end.
Stainless steel screws, as the name suggests, must be made of stainless steel screw wire, and then screw the screw thread. Many of the properties of stainless steel screws are related to stainless steel. Taking into account the properties and organization of stainless steel, understand the properties of stainless steel materials and other aspects. Therefore, it is understood that stainless steel has good mechanical properties such as anti-rust, anti-corrosion, high temperature resistance, etc., then stainless steel screws also have these good mechanical properties. With the increasing quality of stainless steel materials. The mechanical properties of stainless steel screws produced by the screw industry are getting better and better. Anti-rust, anti-corrosion ability, and high temperature and high pressure are getting stronger and stronger.
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 three-tool.
In another embodiment of Guangdong Yueluo Hardware Industry Co., Ltd., the discharge port of the vibrating plate 2 is matched with the screw receiving hole 35, and the screws can enter the screw receiving hole 35 through the discharge port after sorting and sorting in the vibrating plate 2. . Preferably, a guide rail 6 is provided between the discharge port of the vibrating plate 2 and the screw accommodating hole 35, and the screws enter the screw accommodating hole 39 from the discharge port through the guide rail 6. The slotting is carried out, which improves the efficiency and saves the labor cost.
