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 2 and a heat treatment process. The body 2 is set in an "L" shape, with a circular through hole 1 on its left side and a square groove on its right side. 3. Its heat treatment process is characterized by immersing in a suitable quenching medium after heating to austenitization and cooling 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 elongation, breaking, slipping and wear, and has high fatigue resistance and impact toughness, can resist fatigue and impact fracture, and can be well used i...

Abstract

The invention discloses a rotary valve connecting piece of a die opening machine and a heat treatment process thereof. The invention involves a body and a heat treatment process. The body is an L-shaped structure, the left side is provided with a circular through-hole, and the right side is equipped with a square groove. The heat treatment process is characterized by: conducting heating to austenitization, and then immersing the connecting piece into a proper quenching medium to undergo cooling at a fast speed. The rotary valve connecting piece of the die opening machine has enough high tensile strength to resist elongation, snapping, thread slipping and wear, has high fatigue resistance and impact toughness, and can resist fatigue and impact fracture, thus being well applicable to the mold opening machine.

Description

technical field [0001] The invention relates to a mechanical product, in particular to a rotary valve connecting piece of a mold opening machine and a heat treatment process thereof. Background technique [0002] The rotary valve connecting pieces 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, and they cannot resist fatigue and impact fracture, so they cannot be well It is used in the mold opening machine. Contents of the invention [0003] The invention provides a rotary valve connecting piece 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 rotary valve connecting pieces of some existing mold opening machines do not have high enough tensile strength, cannot resist elongation, breaking, slipping and wear, and the fatigue resistance and impact toughnes...
