Summary of information:We have more than ten years of experience in screw industry production. The main products are: countersunk head anti-the...

In the process of completing the adjustment of the position of the object, the nut will move up and down with the entry and exit of the screw, and it cannot make a sound for people to perceive, and it cannot provide people with a position change distance through the action of rotation.

Fig. 1, Fig. 2, and Fig. 3 show that the rivet nut is cut into the required blank from a chemically treated low carbon steel disc, and the blank is placed in the die, and the upper and lower punches are used for shaping to obtain a shaped blank. , and then put the shaped blank in the die, use the punch punch to cold-head out the required brim blank (1) and the deformed skirt (2), and then use the punch punch in the die to continue Cold heading out the brim blank (1) and the deformed skirt (2). Then put the semi-finished material into the concave die and use the punch of the punch to continue to squeeze the threaded hole (3) of the nut tapping skirt, and then put the semi-finished blank into the concave die and use the upper punch and the lower sleeve to drop it. material. There are fish teeth (6) below the brim; the outer side of the lower end of the threaded hole is provided with a chamfer (5); the cross-section of the thread of the inner wall of the threaded hole is an isosceles trapezoid, and the upper bottom of the trapezoid is a concave arc (4), In this way, the riveted object is firmly connected to the rivet nut.

The retaining ring with an open ring structure is a commonly used mechanical part. It has standardized design standards. Its main function is to fasten the ring-shaped parts on the shaft, which can prevent other parts mounted on the shaft from moving. kinds of fasteners. In the prior art, the retaining ring is mainly processed by stamping, which has the following defects: 1. The material utilization rate is low;

Stainless steel rivet nuts are used on rail passenger cars, highway passenger cars, and ship parking. The main function is the non-structural bearing bolt connection. The main advantage of stainless steel rivet nuts is that there is no operating space on the back of the substrate, and the quality is extremely light. Today, the editor will talk about the selection principles of stainless steel rivet nuts and their uses: 1. The mechanical properties of stainless steel rivet nut materials, especially the strength requirements; Corrosion resistance requirements of materials;

The purpose of Guangdong Yueluo Hardware Industry Co., Ltd. is to provide a cement screw that is easy to install and can be removed in view of the shortcomings of the above-mentioned cement nails that cannot be disassembled and the expansion screws are not easy to install for the first time. Guangdong Yueluo Hardware Industry Co., Ltd. is a cement screw, which is realized by the following technical solutions. The cement screw is composed of a nail tip and a nail body. There is a thread at the back of the nail body. This thread can be an internal thread or an external thread. . When using, use a hammer to drive cement screws into the cement, and you can use ordinary screws or nuts to freely screw in and out to install and fix objects. Compared with the existing technology, Guangdong Yueluo Hardware Industry Co., Ltd. has the advantage that there are internal threads or external threads on the back of the cement screw, so it is not only easy to install for the first time, but also the objects to be installed can be disassembled repeatedly. Used as a fastener when installing objects on cement that may need to be dismantled.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: butterfly single-sided embossed washers, chrysanthemum cushion mesons, blackened high-brightness bolts, semi-circle head plum blossom bolts and other products, we can provide you with Provide the right fastener solution for you.
