Summary of information:We have more than ten years of production experience in the screw industry, the main products are: T20 Torx screws, larg...

T-bolt, the European standard is called hammer bolt, the material is carbon steel, the surface is galvanized or nickel-plated, the T-bolt can be directly put into the groove of the aluminum profile, and it can be automatically positioned and locked during the installation process. Used in conjunction with the blue nut, it is a standard matching connector when installing corner fittings. It can be selected and used according to the profile groove width and different series of profiles. When the T-bolts on the market are installed with the installation channel, the bolts need to be placed into the channel from the port of the channel, and then tightened when moving to the designated position. The bolts are easy to rotate during installation, and the connection is not tight. Therefore, it is necessary to propose a mounting structure that uses T-bolts and grooves.

kind of screw provided by Yueluo, the rod body of the screw rod has a thread segment, one end of the thread segment is provided with an annular convex ring on the outer peripheral surface of the rod body, and the distance between the convex ring at the front end of the screw threading direction and the rod core Smaller than the nominal size of the threaded section or the distance from the rear end of the bead to the rod core in the screwing direction is greater than the nominal size of the threaded section.

In the existing production technology, such as construction machinery, double nuts are often used to fasten the workpiece. With the long-term vibration in the working environment, there is a thread gap between the nut and the bolt, and there is no self-assembly between the nut and the bolt. Locking action, the relative displacement between the nut and the bolt will occur under the action of vibration, resulting in the loosening of the nut and the bolt and the loss of the tightening effect.

The process factors that affect the quality of high-strength fasteners include steel design, spheroidizing annealing, peeling and dephosphorization, drawing, cold heading, thread processing, heat treatment, etc., and sometimes the superposition of various factors.

Cylindrical pins are generally used to connect, lock parts or for assembly positioning, and can also be used as parts of safety devices. The cylindrical pin is fixed in the pin hole by interference fit with the pin hole to fix parts, transmit power, or act as a positioning member. The prior art cylindrical pin press-fitting is shown in Figure 1. This kind of cylindrical pin prevents the cylindrical pin body from withdrawing through the locking force and axial friction force brought by the interference fit between the cylindrical pin body and the pin hole. However, the interference of the cylindrical pin body will gradually decrease during use, so that the firmness of the connection and the positioning accuracy will gradually decrease. Therefore, the cylindrical pin can be easily withdrawn during use, resulting in potential safety hazards.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: full-tooth 12.9-grade screws, angular nuts, blackened fine-tooth screws, internal and external thread bolts and other products, we can provide you with suitable tightening. piece solution.
