Abstract

The invention provides a manufacturing method of an improved screw with a metal gasket. By adoption of the manufacturing method, the technical problems that in the prior art, a relevant manufacturingmethod for screws is no available, mass production of screws cannot be achieved, and the manufacturing speed is low are solved. The manufacturing method of the improved screw with the metal gasket comprises the following steps of a, manufacturing of a screw, specifically, the screw is manufactured through the processes of blank making, forming, groove pressing and thread rolling; b, manufacturingof the metal gasket, specifically, metal powder is heated to be molten, is poured at the temperature of 1720 DEG C after being molten, is cooled to the temperature of 870 DEG C and then is placed in an incubator to be cooled to the room temperature, and finally, tempering is conducted at the temperature of 350 DEG C to obtain the metal gasket; and c, assembling, specifically, the metal gasket is assembled on the screw on an assembly line for assembling, so that the screw with the metal gasket is obtained. The manufacturing method has the advantage of being fast in manufacturing.

Description

technical field [0001] The invention belongs to the technical field of machinery and relates to a method for manufacturing an improved 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 c...
