A high-efficiency surface heat treatment device and heat treatment method for metal parts

Abstract

The invention discloses an efficient surface treatment device and heat treatment method for metal pieces. The efficient surface treatment device comprises a heat treatment box, and a moving hole is formed in the bottom end of the heat treatment box. The two ends in the moving hole are in sliding connection with push plates, a spring groove is formed in one side of the bottom end of each push plate, a plurality of first springs are welded in the spring grooves, and the bottom ends of the first springs are welded to the top face of a first limiting rod. After heating is finished, a worker movesthe push plates to enable the push plates to move in the moving hole, the first limiting rod is moved out of one corresponding groove and moves into the other corresponding groove, and then the push plates are horizontally moved, so that the first limiting rod horizontally moves in the corresponding groove; and therefore the heated metal pieces and the preheated metal pieces are moved out at the same time, the worker does not need to separately move the heated metal pieces and the preheated metal pieces, and therefore the metal piece moving time is shortened, the labor intensity of the workeris reduced, and the work efficiency of the worker is improved.

Description

technical field [0001] The invention relates to the technical field of metal heat treatment, in particular to a high-efficiency surface heat treatment device and a heat treatment method for metal parts. Background technique [0002] Metal heat treatment is to heat a metal or alloy workpiece in a certain medium to a suitable temperature, and keep it at this temperature for a certain period of time, and then cool it in a different medium at different speeds. A process in which the microstructure is used to control its performance. When processing pipes or solid rods, heat treatment is required to eliminate the internal stress of the material and improve the mechanical properties of the material. [0003] At present, the heat treatment of pipes or solid rods needs to be preheated, but when placing pipes or solid rods, the staff needs to take out the pipes or solid rods in the heating chamber, and then place the preheated pipes or solid rods. At the same time, the tubes or soli...

Problems solved by technology

[0004] The present invention provides a high-efficiency surface heat treatment device and heat treatment method for metal parts, which can effectively solve the problem that pipes or solid rods need to be preheated for heat treatment in the above-mentioned background technology, but when placing pipes or solid rods, it is necessary to After the staff takes out the pipes or solid rods in the heating chamber, they place the preheated pipes or solid rods. They cannot take the pipes or solid rods after the end of the heat removal and the end of the preheating at the same time, so as to prolong the working efficiency of the staff and at the same time Can increase the labor intensity of the staff
