Three-stage heating type metal heat-treatment furnace

Abstract

The invention discloses a metal stamping stamping-member heat-treatment apparatus, and relates to the field of metal heat-treatment. The metal stamping stamping-member heat-treatment apparatus comprises a furnace body, wherein the furnace body is provided with a flue channel, a heating chamber is arranged in the furnace body, an undertaking plate is arranged on the bottom portion of the heating chamber, and heating zones are further arranged in the heating chamber, comprise a first heating zone, a second heating zone and a third heating zone, and are arranged on the undertaking plate. The metal stamping stamping-member heat-treatment apparatus has the following advantage that: the three-stage fractional heating process is adopted, such that temperature difference in the furnace body is small, the metal can be uniformly heated, and the heat-treatment effect is ideal.

Description

[0001] Technical field [0002] The invention relates to the field of metal heat treatment. Background technique [0003] At present, the heat treatment of metal stamping parts is to heat the entire heating zone to a predetermined temperature at one time. With this process design, the temperature difference in the entire heating zone is large, so that the metal parts are heated unevenly during heating, which affects the heat treatment effect of the metal parts. If it is heated for too long, it will cause the metal to be heated for too long at high temperature, and it will deform when it is cooled, and the hardness of the metal will decrease and the brittleness will increase, which will seriously affect the quality of metal stamping parts. Summary of the invention [0004] The purpose of the present invention is to provide a heat treatment device for metal stamping stamping parts with uniform heating and fast heating speed. [0005] The technical solutions adopted to achieve the abov...

Problems solved by technology

[0003] At present, the heat treatment of metal stamping and forming parts is to heat the whole heating area to a predetermined temperature at one time. Such a process design has a large temperature difference in the entire heating area, which makes the metal parts heated unevenly when heated, which affects the heat treatment effect of the metal parts.

If it is heated for too long, it will cause the metal to be heated at high temperature for too long, and it will deform when it cools, and the hardness of the metal will decrease and the brittleness will increase, which will seriously affect the quality of metal stamping parts.
