Manufacturing method of super-grade screw foot screw

　　Special Screwsfoot screw manufacturing method:

Special grade screw foot screw technology field:

The invention belongs to various product accessories of screw type and belongs to a special special grade screw foot screw.

Today's screws are mostly composed of three parts: a screw head, a screw and a screw head. The screw head is a simple flat and directly connected to the screw as a whole, and the screw head and the screw are connected by silk. Due to the small area of the screw head and the small force area in use, the consolidation strength of the screw head and the accessories is small; the screw head is directly connected with the screw, which is not suitable for some special accessories. This screw due to its own structure force is not strong (screw structure parts separation), resulting in screw sliding, serious damage.

The purpose of the present invention is to make the screws connecting various product accessories have reliable stability, prevent the hazards of vibration, pressure, collision and other factors, and propose a special foot screw with earthquake resistance, compression resistance and collision resistance to extend its Use life, reduce replacement and maintenance costs.

The special grade screw foot screw includes the bottom, the nut rod and the screw head matching the nut rod thread. The bottom and the nut rod are connected as a whole through a round screw seat and a round rod, and the screw head is composed of a cover plate and a cover head.

The cover plate is a circular plate, and the surface layer at the bottom of the plate has a circular groove and protrudes from the surface layer at the bottom. The center of the cover plate is a round hole, which has the same diameter as the center hole of the hexagonal cap on the upper part of the cover plate, and is connected with the round hole of the round cover plate and the round hole of the hexagonal cap.

The screw can be made by special mold casting processing, or it can be made by mechanical mold extrusion of manganese steel and round steel.

Special foot screws have the following remarkable characteristics: 1. Protect the components and accessories of the product from deformation or damage under the action of normal impact, pressure and impact, and continue to play their functions; 2. The firmness, reliability and stability combined with the product and product accessories greatly exceed the effect of the original screw, which not only ensures the use quality, but also increases the use efficiency; 3. The special screw of the patented technology of the utility model is easy to replace and install during use; 4. The special screw has simple structure, reasonable structure, convenient production and manufacturing; and has the characteristics of flexibility, simplicity, durability, and economy.
