How Should We Do Self-clinching Screw Headshot?

- Oct 18, 2018-

In the fastener industry, the nut looks at the "1+X" plan. It is not difficult to see that the development of high-end and high-tech is still the main theme. Secondly, the green environmental protection theme will be strengthened, and the energy-saving and environmental protection in the production process and production of green. The products in the manufacturing direction will be the main direction; then, intelligent manufacturing, making full use of the production, management and marketing of the Internet and intelligent machinery to optimize the traditional production, warehousing, management and sales models of the fastener industry in China; Investigate, truly concentrate on the industry, adhere to the "artisan spirit", research and develop new products, good products, cutting-edge products, and thus penetrate into the high-end field; improve and optimize the enterprise personnel system, pay attention to talents, reuse talents......

The rivet nut is a kind of self-clinching nuts. It is mainly used on thin plates or sheet metal, and has a circular shape with embossed teeth and guide grooves at one end. Products have many advantages, so they are used in many industries, and there are many models, and with the continuous innovation of technology, products are becoming more and more popular.

Manufacturers who produce self-clinching nuts often encounter the phenomenon of head squeezing screw heads. Many heads about rivet screws are not very well understood; why is the rivet screw headshot? What causes the head of the rivet screw to burst? This is a list of problems, the following is told by the manufacturer of the screw shield

    The reasons for the head burst after forming the rivet screw are as follows:

1, mainly the problem of the number of raw materials for the rivet screw line. The initial pressing stage of the rivet screw sheet touches the beginning of the upper sheet from the punch 1 and stops when the push rod 5 reaches the dead point. In this process, the upper sheet is bent and deformed in the convex attack, and the local episode is plastically deformed. At this stage, the upper and lower sheets are mainly elastically deformed with a small amount of plastic deformation.

2, the self-clinching nuts is a new type of application on thin plates or sheet metal. The principle is that the embossed tooth is pressed into the preset hole of the sheet metal, and the diameter of the general pre-positioning hole is slightly smaller than the pressed-in outer diameter of the rivet screw, and the outer diameter of the rivet screw is pressed into the plate through the pressure, thereby causing The periphery of the hole is plastically deformed, and the deformed object is pushed into the guiding groove, and then the locking effect is exerted. The rivet nut column is divided into the fast-cut steel through-hole rivet nut column SO-type, stainless steel through-hole rivet nut column SOS type, fast-cut steel blind hole rivet nut column BSO type and stainless steel blind from the form of raw materials and internal threads. There are four types of hole self-clinching stanodffs BSOS, which can be used in different operating environments. It may be that the rivet screw wire is not annealed. The raw material of the rivet screw line is too poor, resulting in the output of the metal rivet screw headshot. It is a Phillips screw, and there should be no big problem when it is done. The rivet screw is a headshot after molding.
