Summary of information:We have more than ten years of experience in screw industry production, the main products are: GB858, heavy hexagonal sc...

The height of the existing assembly devices is fixed, and the height of the workers is different, so it is very inconvenient to use, resulting in a decrease in efficiency. With the progress of science and technology and the development of society, people have proposed higher assembly devices. Therefore, we propose a shaft card assembly device to solve the above problems.

The anchor bolts of some metallurgical industrial equipment are detachable, that is, the anchor bolts are not directly anchored in the foundation concrete, but anchored in the T-bolt sleeve (T-bolt sleeve hereinafter referred to as sleeve) , The sleeve is constructed together with the foundation and anchored directly in the foundation. The T-bolt is inserted into the sleeve when the equipment is installed, and the T-bolt can be removed from the sleeve when the equipment is replaced.

hand screw is a screw with a plastic head, and the user fixes the hand screw by turning the plastic head by hand. At present, a hand-tight screw is disclosed in the market publication number CN202203253U, which includes a plastic head and a screw rod, the plastic head and the screw rod are connected together, and the height of the plastic head is higher than that of an ordinary screw, and the height is 6 cm. The screw of the hand screw is fixed in the plastic head by glue. After a period of use, the aging of the glue leads to the loosening of the screw and the plastic head. When the plastic head is stressed, the screw rod comes out of the plastic head, which affects the normal use of the hand screw.

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.

Stamping die is a special process equipment for processing materials into parts in cold stamping processing, called cold stamping die. Stamping is to use the die installed on the press to apply pressure to the material at room temperature to make it produce Separation or plastic deformation to obtain the required parts of a pressure processing method, the technology generally used is to make corresponding holes and punches on the template, this method cannot meet the requirements for small batches and short delivery time products , the relative cost is relatively high, so a rivet die structure is required to improve the above problems.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: smooth screws, rivet nuts, enlarged metal washers, 3304 stainless steel screws and other products, we can provide you with suitable fasteners for you solution.
