Embodiment Construction

[0009] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0010] As shown in the figure, the present invention includes a body 1 and a heat treatment process. The body 1 has a cylindrical structure on its top, a square notch 5 on its underside, and a circular notch 5 in the middle of the body. The through hole 2, the lower part of the body is set as a triangular structure 3, and the bottom is provided with an internal threaded hole 4. The heat treatment process is characterized by immersing in a suitable quenching medium after heating to austenitization to cool at a faster rate .

[0011] When selecting the quenching medium for the heat treatment process, sufficient cooling capacity should be ensured first, that is, the quenching medium with high cooling capacity should be selected, and distortion and quenching cracking should also be prevented.

[0012] The invention has high enough tensile strength to resist elon...

Abstract

The invention discloses a swing arm fixing piece of a mould opening machine and a heat treatment technology thereof. The swing arm fixing piece comprises a main body and a heat treatment process, wherein the upper part of the body adopts a cylindrical structure, and a square notch is formed in the lower side of the main body; a circular through hole is formed in the middle of the main body, the lower part of the body adopts a triangular structure, and an inner threaded hole is formed in the bottom of the main body. The heat treatment technology is characterized in that after being heated for austenitizing, the swing arm fixing piece is immersed into a suitable quenching medium to cool down at a quick speed. The swing arm fixing piece has high enough tensile strength to resist lengthening, snapping, slipping off and wearing, and has higher fatigue resistance and impact toughness to resist the fatigue and impact fracture, so that the heat treatment technology disclosed by the invention can be applied to the mould opening machine well.

Description

technical field [0001] The invention relates to a mechanical product, in particular to a swing arm fixing part of a mold opening machine and a heat treatment process thereof. Background technique [0002] The swing arm fixtures of some mold opening machines on the existing market cannot resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough to resist fatigue and impact fracture, so they are not very good It is used in the mold opening machine. Contents of the invention [0003] The invention provides a swing arm fixing part of a mold opening machine and a heat treatment process thereof. [0004] The purpose of the present invention is to solve the problem that the swing arm fixing parts of some existing mold opening machines do not have high enough tensile strength to resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughness are not high enough. It can't resist fatigue and ...
