Description

Technical Field

[0001] The utility model relates to the field of tooling, in particular to a heat treatment tooling sling which can adapt to different sizes. Background Art

[0002] Heat treatment refers to a metal hot processing technology that uses heating, heat preservation and cooling to obtain the expected structure and performance of the material in the solid state. Surface heat treatment of steel parts can obtain a high-hardness martensitic structure on the surface, while retaining the toughness and plasticity of the core, improving the comprehensive mechanical properties of the workpiece. Workpieces such as some shafts, gears and parts that bear deformation loads can be made to have a higher wear resistance on the surface through surface heat treatment, which greatly improves the overall fatigue resistance of the workpiece. When heat treating the workpiece, it is necessary to lift the workpiece with a hoist to improve work efficiency and avoid the problem of too fast cooling during the transfer of the workpiece. When the workpiece is heat treated and quenched, it is necessary to lift it, which will generate internal stress and may cause the workpiece to shake when it is lifted or moved, which will bring hidden dangers to the operator.

[0003] The existing heat treatment tooling hanger and the mounting frame hoisted on the lower side of the hanger, the mounting frame has a mounting hole for the workpiece to be vertically set up, the heat treatment tooling also includes a disc-shaped top cover, a circular support ring and a long metal chain, the top cover is horizontally fixed on the hanger and the outer edge of the top cover protrudes from the outer side of the hanger, the number of chains is several and the upper ends of the chains are respectively fixed on the outer edge of the top cover, the several chains are closely distributed around the axis of the top cover, the lower end positions of the several chains are all lower than the bottom surface of the mounting frame, the support ring is set on the outer side of the mounting frame and the corresponding positions on the several chains are fixed to the outer side of the support ring. The heat treatment tooling can slow down the cooling speed of the workpiece after heat treatment.

[0004] The existing technology is not convenient for hoisting workpieces of different sizes, and does not solve the problem of shaking of the workpieces. Utility Model Content
