GB6177 Hexagon Flange Nuts - Grade GB55 Hexagon Thick Nuts GB56 Hexagon Extra Thick Nuts GB1229 Large Hexagon Nuts (High Strength for Steel Structure) Lock Nuts Other Names: Root Nuts, Lock Nuts, and Nuts. Purpose: To lock the outer joint of the through wire or other pipe fittings. The working principle of the nut is to use the friction between the nut and the bolt for self-locking. However, the reliability of this self-locking is reduced under dynamic loads. In some important occasions, we will take some anti-loosening measures to ensure the reliability of the nut locking. Among them, the use of lock nuts is one of the anti-loosening measures.

Fasteners are an indispensable necessity in our lives and are used to flexibly fix two objects. However, in applications such as automobiles, large construction machinery and factories, the nuts often come loose and then fall off, resulting in frequent dangers and great dangers. Threats to people's lives and property.

In order to achieve the above purpose, Guangdong Yueluo Hardware Industry Co., Ltd. discloses a tamper-proof nut, which includes an upper part, a lower part, and an inner threaded hole penetrating the upper part and the lower part. The cross section of the inner threaded hole is circular, so the The lower part is an equilateral triangle cylinder, and the apex of the equilateral triangle cylinder has an arc structure, and the arc structure includes a left arc part and a right arc part with the angle bisector as the center of symmetry, and the lower part has an arc structure. A tamper-proof portion protruding from the lower surface is formed, and the tamper-proof portion is arranged at the left arc portion or the right arc portion.

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.
