Summary of information:We have more than ten years of production experience in the screw industry. The main products are: knock-on-lock rivet k...

For the detection of the shear force of the elastic cylindrical pin, the method and the tooling are marked, but the tooling is only a means to be used on the test bench, and the process of embedding the cylindrical pin into the tooling is a more difficult process. Generally, it is used to place the tooling on a plane, a vise, a simple V-shaped, and a simple U-shaped fixture. Originally, the elastic cylindrical pin was detected by hand or pliers to hold the cylindrical pin and align the pin with the outer cylinder of the tooling. Use a hammer to smash the shear holes, and adjust the concentricity of the inner and outer cylinders of the shear holes of the tooling from time to time. The limitations, dangers and difficulties of this assembly method are relatively large, often testing a set of cylindrical pins, which takes a lot of time and is difficult for lesbians to complete.

Most of the existing screws use an integral metal structure, and there are still some problems, such as large weight, high cost of materials, wear resistance, hardness, rust resistance, corrosion resistance, high and low temperature resistance, brittleness, toughness, etc. Many occasions cannot meet the needs of production, and further improvements are needed to improve production efficiency, reduce costs, improve safety, and prolong the service life of screws.

1. Precautions for the quality of high-strength bolts or screws and flat washers assemblies. The surface of the Phillips hexagon combination screw should be checked for burrs or scratches. There is no oil stains, or rust. To test the material of the combination screw, the strength of the grade used in different high strengths should be consistent with it. Second, the combination bolt and nut should be used together with the same grade as the nut, and the same grade should be used together. Third, when installing and using combined bolts, it should be in reasonable weather conditions and should not be operated in the rain. Fourth, when installing, it is forbidden to use excessive force and excessive force. Lead to sliding teeth, or locking phenomenon.
