Service HotlineSprinkle the excess standard spring washer 7 on the positioning plate 12-1 on the spring washer positioning plate 2, and shake the spring washer positioning plate 2 by hand. After a short time, the spring washer 7 will be positioned and arranged on the upper positioning plate 12-1. In the upper spring washer hole 2-7, since the width of the opening groove 12-32 of the baffle plate 12-3 is smaller than the diameter of the spring washer hole 2-7, and the thickness of the upper positioning plate 12-1 is designed according to the thickness of the spring washer 7, Only one spring washer 7 can be accommodated in the spring washer hole 2-7 of each upper positioning plate 12-1, and the excess spring washer 7 is cleaned with a brush.
Guangdong Yueluo Hardware Industry Co., Ltd. has upgraded and combined the fastening nut and the hexagonal nut to ensure the original function of the nut. The nut can be easily and safely disassembled by preparing practical small parts. The inner diameter of the lock ring is 0.1mm larger than that of the hexagonal nut, which is convenient for installation.
The application range of the oil pump is very wide. When it is used, the oil pump needs to be assembled. During the assembly process, when the pin is driven into the pin hole, it is generally held by the operator with a hammer, and then aiming at the top of the pin to press. Into the hole, due to the relatively high tolerance requirements for the depth of the pin pressing and the side clearance (the gap between the pin and the groove wall), the traditional operation method not only causes a high rejection rate and a long training time for personnel, but also The slow processing speed affects the production efficiency.
In specific implementation, the axial three-dimensional shape of the nut and the screw head is in the shape of a pentagonal frustum, the elastic surface of the screw is parallel to the center line of the bolt, and the upper contour line is arc-shaped; the screw can be full or partial thread; the top of the screw head The shape is round.
At present, injection molding screws are widely used in various electronic and automotive components, including a body, the middle of which is provided with a through hole 3, the body head 1 has a hexagonal cross-section, and the tail 2 is provided with screw teeth. When in use, the middle through hole 3 of the body will first put the wire harness, and then fix it by injection molding from the head I, and the threads of the tail 7 should be connected and installed with other components. Because the head I of the main body is hexagonal, the torque provided after injection molding is insufficient. Therefore, after the external thread is installed and connected with other components, the head is prone to slip, the installation is not reliable, and there is no push-pull force, resulting in product failure and increased safety hazards.
We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: waterproof pull rivet nuts, 304 rivets, single-head hexagonal iron columns, O-type hanging nuts and other products, we can provide you with suitable fastening products piece solution.
