Swing arm connecting piece of mold opening machine and heat treatment process of swing arm connecting piece

Abstract

The invention discloses a swing arm connecting piece of a mold opening machine and a heat treatment process of swing arm connecting piece. The swing arm connecting piece comprises a main body and a heat treatment process, wherein a cylindrical structure is arranged above the main body, a square notch is formed in the right side of the main body, a circular through hole is formed in the middle of the main body and is arranged into a first through hole, two square crosspieces are a first crosspiece and a second crosspiece respectively and are respectively arranged on the upper side and the lower side of the main body, a movable connecting piece is arranged below the cylindrical structure, a through hole is formed in the middle of the cylindrical structure and is arranged into a second through hole, and an arc-shaped structure is formed at the bottom of the main body; the heat treatment process has the characteristic that after being heated and austenitized, the swing arm connecting piece is immersed into a proper quenching medium to be more quickly cooled. The swing arm connecting piece has high enough tensile strength to resist elongation, break, sliding and abrasion and higher fatigue resistance and impact toughness to resist the fatigue resistance and the impact fracture and can be better applied to the mold opening machine.

Description

technical field [0001] The invention relates to a mechanical product, in particular to a swing arm connector of a mold opening machine and a heat treatment process thereof. Background technique [0002] The swing arm connectors 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 connector 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 connectors 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 impa...
