Abstract

The invention provides a manufacturing method of a screw with a metal gasket, and solves the technical problems that no relevant manufacturing method is applied to an existing screw, batch productioncannot be realized and manufacturing speed is slow. The manufacturing method of the screw with the metal gasket comprises the following steps: a, manufacturing the screw: manufacturing the screw through processes of blank manufacturing, molding, grooving and thread rolling; b, manufacturing the metal gasket: heating and fusing metal powdery materials, conducting pouring at 1500 DEG C to 1800 DEG Cafter the metal powdery materials are fused, conducting cooling to 800 to 900 DEG C, putting the metal powdery materials into an insulated cabinet and cooling the metal powdery materials to a room temperature, and finally performing tempering treatment at 280 DEG C to 380 DEG C to obtain the metal gasket; and c, assembling: assembling the metal gasket onto the screw through an assembly productionline to obtain the screw with the metal gasket. The manufacturing method of the screw with the metal gasket disclosed by the invention has the advantage of high-speed manufacturing.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a method for manufacturing a screw with a metal washer. Background technique [0002] The screw is a tool for tightening the parts of the object step by step by using the physical and mathematical principles of the oblique circular rotation and friction of the object. When using ordinary screws on the market to fasten objects, because the pitch of the thread is fixed, the locking force of the screw is relatively stable when tightening, and the cooperation of gaskets is often required to lock and fix the relative position. In order to improve the stability of the fastened connection, the screws are not easy to loosen. [0003] After retrieval, such as the Chinese patent literature discloses a screw with a washer, the application number is 2014106929562. This screw with gasket includes a screw body and a gasket pierced on the screw body. The screw body includes a screw cap and a s...
