Pins are widely used. In the connection of the rotating mechanism of two moving components, such as the crank mechanism, the turning mechanism, the connection between the hydraulic cylinder and the moving parts, the pins are used. kind. In order to ensure the normal use of the running equipment and prevent the cylindrical pin from slipping out and falling off during use, some anti-falling methods are usually used at the head of the pin, such as 1. Drill holes and insert cotter pins to prevent the pins from slipping out; 2. The external thread is tightened with a nut to prevent the pin from slipping out; 3. The slot is clamped with a circlip to prevent it from slipping out, etc. These measures make the cylindrical pin very practical in the case of infrequent disassembly and assembly, but in the actual use of the field, in order to prevent the collision of some equipment during each troubleshooting or maintenance, the pin needs to be pulled out and turned up, etc. After the failure or maintenance is completed, put down and then insert the pin to restore, this process will bring trouble to the actual operator. For example, special tools must be brought with you every time you disassemble and assemble the pin, and the split pin or the circlip is easily damaged after repeated disassembly and assembly. , In order to save trouble, the operator sometimes uses iron wire to thread or fasten it instead, and even does not remove the pin for the sake of speed and convenience, which is easy to cause damage to the equipment when dealing with faults.
flat washer, an annular groove is formed on the outer side of the upper surface of the flat washer, and a sealing ring is embedded in the annular groove, at least five circularly equidistantly arranged cylinders are fixed on the upper surface of the flat washer, and the The upper surface of the flat washer is provided with a circular hole that communicates with its bottom, a collar is arranged in the circular hole, an upper circular ring is fixed above the collar, a lower circular ring is fixed below the collar, and the upper circular The diameter of the ring is the same as the diameter of the lower ring, the diameter of the collar is smaller than the diameter of the upper ring, the diameter of the collar is consistent with the diameter of the circular hole, and there are at least three equally spaced holes in the middle of the outer wall of the flat washer. A circular groove, the outer wall of the flat washer is fixed with at least three reinforcing blocks staggered with the circular groove, and the reinforcing blocks and the flat washer are welded into one piece.

Guangdong Yueluo Hardware Industry Co., Ltd. has a simple structure, low processing difficulty, and convenient riveting. The whole pin has the same diameter except for the annular groove. The drawn wire can be directly used, which saves the cost of materials and machining costs, and improves the production speed and efficiency. The structure does not require high machining accuracy of the hole, which can effectively reduce the machining cost and the rework rate of the parts.
The manual dismantling of the rivets of the automobile frame delays the production cycle of the product and increases various production costs, so a special tooling is desperately needed to meet the actual needs.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: oxidized black high-strength hexagon nuts, small semi-circle head bolts, left-hand bolts, washers and other products, we can provide you with suitable products for you. Fastener Solutions.
