Description

Special wedge-shaped clamping heat treatment tool for slender strip-shaped parts

Technical Field

The utility model relates to a part clamping problem when handling high temperature and tempering for the heat treatment clamping of part, in particular to prevention elongated part warp special frock in heat treatment high temperature tempering stage.

Background

A part 100 (shown in figure 1) is an elongated part having an overall length greater than 1000mm, a width of 50mm and a thickness of 10mm, and requires heat treatment of both surface and core hardnesses HRC30-40, requiring high temperature tempering to achieve the heat treatment requirements. The part belongs to a slender thin part, high-temperature tempering can cause high-temperature deformation of the part, twisting can occur at the thickness of 101mm and the width of 102mm, and the part is seriously deformed into a twist shape by a plate material. The parts after heat treatment deformation are difficult to straighten, and if the parts are seriously distorted, the requirements on the flatness and the straightness of the drawing can not be met, and the parts can be directly scrapped. In addition, if the parts are produced in batches, the time spent on the straightening process is too long, and the production efficiency is seriously influenced. Therefore, an external force must be applied to the part to restrict its deformation.

When the high-temperature tempering is carried out, if a heavy object is pressed on the part, the required weight of the pressing block is heavy, the requirement of lifting, moving and overturning of a plurality of parts cannot be met, and the pressing block is pressed on the part too thick to influence the heating and temperature rise of the part to the high-temperature tempering temperature; if press the part reuse threaded connection with two upper and lower thin clamp plates and compress tightly, the deformation can be elongated to used repeatedly high temperature tempering screw thread, and the screw thread can fuse with the screw hole internal thread on the bolt for a long time, can't realize reuse.
