Automatic quenching equipment of bolt fasteners

Abstract

The invention relates to the technical field of automobile fastener machining, in particular to automatic quenching equipment of bolt fasteners. The automatic quenching equipment comprises a heating part, a guiding barrel, a primary cooling oil pool, a secondary cooling oil pool and guiding parts. The heating part is arranged above the primary cooling oil pool, a flow diverting table capable of auto-rotating is arranged in the primary cooling oil pool, multiple flow diverting plates distributed around the circumference of the flow diverting table at equal intervals are arranged on the outer conical surface of the flow diverting table, a servo motor in transmission connection with the flow diverting table is arranged at the bottom of the primary cooling oil pool, the secondary cooling oil pool is laid beside the primary cooling oil pool, the guiding barrel is arranged over the heating part, the two guiding parts are arranged outside the guiding barrel and the heating part separately, anoil injection pipe communicating with the interior of the pool is arranged on the outer wall of the primary cooling oil pool, a discharge tank is arranged on the outer wall of the primary cooling oilpool, and the interior of the secondary cooling oil pool communicates with the oil injection pipe through an oil supply system. The machining quality of the bolts can be remarkably improved.

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.
