Description

Technical Field

[0001] The present application relates to the technical field of metal heat treatment, and in particular to a hanger for metal heat treatment. Background Art

[0002] Heat treatment generally does not change the shape and overall chemical composition of the workpiece. It mainly imparts or improves the performance of the workpiece by changing the microstructure inside the workpiece or the chemical composition on the surface of the workpiece. Metal heat treatment processes can be roughly divided into three categories: overall heat treatment, surface heat treatment and chemical heat treatment. According to the heating medium, heating temperature and cooling method, each category can be divided into several different heat treatment processes. The same metal can obtain different structures and thus have different properties by using different heat treatment processes. In the process of heat treatment of small parts, it is generally necessary to place them in the heat treatment processing area with the help of a carrier device, so that a large number of small parts can be heat treated at the same time, ultimately improving the heat treatment efficiency.

[0003] After searching, the Chinese patent publication number CN212953864U discloses a hanger for heat treatment of silicon steel sheets, including a hanger, a plurality of hangers and a plurality of hooks, the hanger including a column, a plurality of side panels are fixed on the side surface around one end of the column; a plurality of mounting holes are arranged side by side on the side panels; a lifting ring is fixed to one end of the hanger, and a plurality of the hangers are respectively fixed to the mounting holes on the plurality of side panels through the lifting ring and the connecting piece; a connecting block is fixed to the other end of the hanger, a sliding rod is fixed to a surface of the connecting block, and a partition is fixed to one end of the sliding rod; a sleeve is fixed to one end of the hook, and a limiting ring is fixed in the sleeve.

[0004] The above patent has the following shortcomings in a hanger for heat treatment of silicon steel sheets: the above patent adjusts the distance between the hook and the column by the cooperation between the mounting holes on the side panel and the connecting parts, thereby facilitating the fixation of workpieces of different specifications. However, due to the limited number of mounting holes on the side panel and the same adjustment distance each time, the adjustment range is small, which limits the use of this hanger for a large number of workpieces.
