Combined type multifunctional quenching clamp

Abstract

The invention discloses a combined type multifunctional quenching clamp and belongs to the technical field of machine manufacturing vacuum heat treatment production operation. The combined type multifunctional quenching clamp comprises a main material frame and lifting rings. The lifting rings are welded to the two ends of the top of the main material frame correspondingly. C-shaped reinforcing ribs are welded to the surface of the side wall of the main material frame. Multiple C-shaped reinforcing ribs are arranged. Hook bases are arranged on the surfaces of side heads of the C-shaped reinforcing ribs correspondingly. According to the combined type multifunctional quenching clamp, workpieces are partitioned by means of through holes, multiple carrier plates carry out quenching treatment on the multiple workpieces, uniformity of workpiece heating is improved obviously, the uniformity of the quenching cooling process is improved, heat treatment hardness, strength, impact value and othermechanical performance of the workpieces reach the optimal level, the defects that when workpiece original furnace charging amount is large, quenching hardness is not uniform, soft points exist, andthe service life is short are effectively eliminated, the shaft workpieces are vertically clamped and fixed through through holes in the carrier plates, and thus the shaft workpieces can be fixed moreconveniently.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing vacuum heat treatment production operations, in particular to a combined multifunctional quenching fixture. Background technique [0002] In the heat treatment industry of machinery manufacturing, quenching fixtures are an indispensable tool for operators to carry out heat treatment production. [0003] For a long time, in the heating and quenching operations of ordinary quenching box furnaces and vacuum furnaces, the fixtures used are generally welded with heat-resistant steel rods to form material baskets. In actual production, the heat treatment of large workpieces is acceptable, but for many small pieces of heat treatment, especially It is the heat treatment of some shaft workpieces. After they are stacked in the loading basket and quenched by heat treatment, the following heat treatment defects generally occur: uneven hardness, soft spots of the workpiece, serious deformation...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a combined multifunctional quenching fixture, which aims to separate workpieces through through holes. Multiple sets of supporting plates can quench multiple sets of workpieces at the same time, significantly improving the uniformity of workpiece heating, and improving the quenching cooling process. The uniformity of the workpiece heat treatment hardness, strength, impact value and other mechanical properties can reach the best level, effectively eliminate the defects of uneven quenching hardness, soft spots and short service life when the original furnace of the workpiece is large, and pass through the through hole on the supporting plate The vertical clamping and fixing of the shaft workpiece makes the fixing of the shaft workpiece more convenient
