Carrier rack for heat treatment

Abstract

The invention provides a carrier rack for heat treatment. The carrier rack comprises a base, a heating plate and a first supporting plate. Multiple V-shaped grooves are formed in the upper end of theheating plate in the axial direction. The lower end of the first supporting plate is fixedly connected with the base. The upper end of the first supporting plate is hinged to the middle position of the heating plate. A second supporting plate is arranged on the right side of the heating plate and is vertically arranged on the base. A limiting groove cooperating with the right end of the heating plate is formed in the side wall of the second supporting plate. A third supporting plate is arranged at the position of the left side of the lower portion of the heating plate. The upper end of the third supporting plate is arranged on the lower end face of the heating plate in an abutting manner. The lower end of the third supporting plate is hinged to the base. The upper side of the left end of the third supporting plate is connected with a pull rope. According to the carrier rack for heat treatment, the first supporting plate, the second supporting plate and the third supporting plate cooperate so that the heating plate can be in a horizontal or oblique state, pipe fittings can conveniently slide into a water trough or an oil trough for heat treatment after being heated on the heating plate, the automation degree is high, the production efficiency is greatly improved, and product quality is guaranteed.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a carrier for heat treatment. Background technique [0002] Heat treatment is a metal processing process that puts metal materials in a certain medium for heating, heat preservation, and cooling, and controls its performance by changing the metallographic structure of the material surface or inside. The heat treatment process includes heating, heat preservation, and cooling. process. [0003] At present, the heat treatment of pipe fittings is generally placed directly in the heat treatment furnace for direct heating. After the heating is completed, the artificial pipe fittings are usually transferred to a water tank or oil tank for water cooling or oil cooling, which is troublesome, labor-intensive, and the handling efficiency is poor. The quality of the pipe fittings may be affected because the pipe fittings are not transported to the water tank or oil tank for...
