A kind of automatic quenching equipment for bolt fasteners

Abstract

The present invention relates to the technical field of automobile fastener processing, in particular to an automatic quenching equipment for bolt fasteners, which includes a heating component, a guide cylinder, a primary cooling oil pool, a secondary cooling oil pool and a guiding component. On the top of the primary cooling oil pool, there is a splitter table that can rotate in the pool of the primary cooling oil pool. The servo motor connected with the transmission of the diverter table, the secondary cooling oil pool is laid on the side of the primary cooling oil pool, the guide cylinder is set directly above the heating component, the number of guide components is two, and the two are respectively set on the guide cylinder and the outside of the heating part, the outer wall of the primary cooling oil pool is provided with an oil injection pipe connected to the inside of the pool, the outer wall of the primary cooling oil pool is provided with a discharge groove, and the secondary cooling oil pool is connected to the oil injection pipe through the oil supply system. The invention can significantly improve the processing quality of bolts.

Description

technical field [0001] The invention relates to the technical field of automobile fastener processing, in particular to an automatic quenching equipment for bolt fasteners. Background technique [0002] In the mechanical field, the quenching process is a very widely used treatment method. The quenching process refers to heating a certain metal material to a certain temperature and maintaining it for a certain period of time to change its alloy structure. Its main purpose is to improve the mechanical properties of the alloy and increase its corrosion resistance. [0003] Bolts are the most commonly used fastening parts in automobiles and are widely used. At present, the processing of high-strength bolts requires a heat treatment process. In the prior art, when cooling the quenched bolts, the cooling effect is not good. The temperature of the liquid rises suddenly, which is difficult to control, which reduces the subsequent cooling effect on the bolts and the cooling effect ...

AI Technical Summary

Problems solved by technology

At present, the processing of high-strength bolts requires a heat treatment process. In the prior art, when cooling the quenched bolts, the cooling effect is not good. The temperature of the liquid rises suddenly, which is difficult to control, which reduces the subsequent cooling effect on the bolts and the cooling effect is unstable; and the traditional bolt quenching work is mostly manual hand-held clamps to clamp and load the material, which is labor-intensive and the degree of automation is not high enough.
