Problems solved by technology

At present, the processing of high-strength bolts requires heat treatment, but the heat treatment industry in my country basically adopts a single bolt processing method. This method has unstable product quality and low production efficiency, and cannot meet the needs of large-scale production.
[0003] The temperature of the quenching medium will rise after repeated use. When the temperature of the quenching medium rises, it will have an adverse effect on the time and effect of quenching

Abstract

The invention discloses an oil-quenching tank for bolts. The tank comprises a quenching device, a cooling device and a residual liquid dripping device, wherein the residual liquid dripping device is connected to the discharging end of the quenching device, and the cooling device communicates with the quenching device; the quenching device comprises an upper oil feeding tank, a conveying chain plate and an auxiliary oil tank, and the upper oil feeding tank is fixedly installed above the auxiliary oil tank; and the tank further comprises an overflow pipe, the two ends of the overflow pipe communicate with the upper oil feeding tank and the auxiliary oil tank, and the cooling device is used for cooling an oil liquid in the upper oil feeding tank. The invention aims to provide the oil-quenching tank for the bolts. According to the tank, the bolts can be subjected to quenching in batch, compared with an existing mode, the working efficiency is improved, and the labor intensity of workers isreduced.

Description

technical field [0001] The invention relates to the technical field of bolt heat treatment, in particular to a quenching oil tank for bolts. 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. Bolt is the most commonly used fastening part in mechanical equipment, and its application is very extensive. At present, the processing of high-strength bolts requires a heat treatment process, but the heat treatment industry in my country basically adopts a single bolt processing method. This method has unstable product quality and low production efficiency, and cannot meet the needs of large-scale production. [0003] The temperature of the que...
