An online pressure metal heat treatment process and its heat treatment device

Abstract

The invention discloses an online pressure metal thermal treatment process and an online pressure metal thermal treatment device. According to the process, a pressure device is adopted to synchronously heat a workpiece and apply a pressure to the workpiece so as to realize thermal treatment and then discharging and cooling are automatically carried out. The metal thermal treatment device comprises a supporting body, a pressure mechanism, two heating mechanisms, a temperature control device, a time control device and a cooling mechanism, wherein the pressure mechanism comprises first and second pressure bases which are mounted in the supporting body and can be propped against each other and first and second driving mechanisms; first and second profiled grooves are respectively formed in the opposite surfaces of the first and second pressure bases; insulation structures are also arranged on the outer surfaces of the first and second pressure bases; the two heating mechanisms are respectively mounted in the first and second pressure bases; the temperature control accuracy of the temperature control device is 1 DEG C; the temperature control device is mounted outside the supporting body; the time control accuracy of the time control device is 1s; the time control device is mounted outside the supporting body; the cooling mechanism is mounted below the supporting body. According to the online pressure metal thermal treatment process and the online pressure metal thermal treatment device, the fact that the workpiece has qualified performance in the treatment process is guaranteed, and the phenomena of deformation, blowing-out discharging and the like are avoided.

Description

[0001] Technical field: [0002] The invention relates to the technical field of metal heat treatment, in particular to an online pressure metal heat treatment process and a heat treatment device thereof. [0003] Background technique: [0004] Heat treatment is a metal thermal processing process in which metal materials are heated, kept warm, and cooled in a certain medium, and their properties are controlled by changing the metallographic structure on the surface or inside of the material. Heat treatment is the most important strengthening method to improve the strength of metals that can be strengthened by heat treatment. At the same time, it can stabilize the external dimensions of products such as compact appliances and parts, and reduce the internal stress of materials. Different metal materials have different heat treatment temperature ranges. The smaller the temperature range, the higher the control accuracy requirements, and the more uniform and stable the performance ...

AI Technical Summary

Problems solved by technology

[0005] At present, common heat treatment devices include atmosphere furnaces and salt bath furnaces, which heat materials through gas or liquid heat transfer media, which inevitably have disadvantages such as heating lag and slow speed, uneven temperature field, and large temperature fluctuations. Problems such as substandard or uneven performance

During the heat treatment, due to the certain internal stress inside the material, it is easy to deform during the heating process, resulting in defects such as twisting, warping, waving, and side bending of the material, and cannot maintain good external dimensions.

In addition, the existing heat treatment devices are all static heat treatment, which needs to stop the furnace to load and unload materials, which is time-consuming and laborious
