Summary of information:We have more than ten years of production experience in the screw industry, the main products are: iron hollow rivets, t...

Traditionally, the pressure rivets on the product are all beaten by hand by workers, resulting in high scrap rate and low efficiency, and this rivet is not a traditional rivet, so it is difficult to locate and requires high pressure. The rivets are thin, and the pressure is too large to cause deformation of the rivets. If the pressure is too small, it cannot be riveted. Without special positioning and tooling, it cannot be riveted on the riveting machine. The quality of the products produced in this way is difficult to guarantee, and the quality levels of the products in the same batch are uneven. Affect delivery time.

Nuts are parts that tightly connect mechanical equipment. Through the inner threads, nuts and bolts of the same specification can be connected together. For example, M4-P0.7 nuts can only be connected with M4-P0.7 series bolts (in the nut). Among them, M4 means the inner diameter of the nut is about 4mm, and 0.7 means that the distance between the two threads is 0.7mm); the same is true for American products, for example, a 1/4-20 nut can only be matched with a 1/4-20 screw ( A 1/4 finger nut has an inner diameter of about 0.25 inches, and 20 fingers have 20 teeth in each inch).

screw is a common threaded connection part, which is mainly used to fix a part on the connection body. When it is necessary to connect, use the screw to pass through the hole on the connected parts, and screw the external thread on the screw into the connecting body to tighten it; The coupling part is separated from the coupling body. Existing common tools for screw disassembly and assembly are generally adjustable wrenches, open-end wrenches, Torx wrenches, socket wrenches, Allen wrenches, flat-blade screwdrivers, cross-shaped screwdrivers, etc., and a screw can only be disassembled with one or one type of tool. Assembly work; when the types of tools are not complete, the screw disassembly and assembly work is difficult to complete, and the screw disassembly and assembly work is greatly limited by the tools.

Shaft retaining ring (hereinafter referred to as retaining ring) is a very common part and is widely used in shaft parts. The existing solution for pressing the retaining ring is: place the retaining ring sleeve in the chamfering section or the guiding section of the shaft head, and then use an indenter whose inner hole diameter is larger than the diameter of the shaft head to press the retaining ring into the groove, and then press the retaining ring into the groove through the shaft head. The retaining ring is combined with the slot to prevent the indenter from continuing to move downward.

A rivet is a nail-shaped object with a cap on one end: in riveting, the parts being riveted are joined by their own deformation or by interference. There are many types of rivets, and they are informal. However, the two ends of conventional rivets are concentric, which is not suitable for special occasions.

We have many years of experience in the production and sales of screws, nuts, flat washers, etc. The main products are: lifting ring fisheye screw screws, gypsum board screws, galvanized lock nuts, heavy nuts and other products, we can provide you with suitable fastening products piece solution.
