Abstract

The invention discloses a heat treatment machining device for hot work die steel. The heat treatment machining device comprises a shell, a packing door, a rotating platform, a platform rotation driving part, at least one fixing assembly, an overturning assembly and a clamping and rotating assembly, wherein a cavity is formed in the shell; the rotating platform is arranged in the cavity; the packing door is located above the rotating platform, one part of the packing door is arranged in the cavity, the rest part of the packing door extends out of the shell, and the packing door can divide the cavity into a heat treatment cavity and a cooling cavity and can reciprocate in the cavity; the platform rotation driving part is connected with the rotating platform through a rotating connecting part, so as to drive the rotating platform to rotate; the fixing assemblies are arranged on the rotating platform, so that the hot work die steel can be installed; the overturning assembly is arranged on the packing door and extends into the cooling cavity; and the clamping and rotating assembly is arranged on the shell. According to the device, the problem that in the prior art, die steel cracks after being treated by a heat treatment machining device is solved.

Description

technical field [0001] The invention relates to post-treatment of hot work die steel, in particular to a heat treatment processing device for hot work die steel. Background technique [0002] The main feature of the working conditions of the hot work die is that it is in contact with the hot metal, which is the main difference from the working conditions of the cold work die. Hot working dies include hammer forging dies, hot extrusion dies and die-casting dies. Hot work die steel is the raw material for making hot work dies. It has appropriate hardness requirements, focusing on red hardness, thermal conductivity and wear resistance. [0003] In order to improve the mechanical properties such as hardness and toughness of hot work die steel, it is necessary to carry out heat treatment on hot work die steel. The heat treatment process of hot work die steel plays a decisive role in its structure and performance. The purpose of heat treatment is to change the structure of steel...
