Abstract

The invention relates to a heat-treating device, in particular to a quenching device with full-size trap parts. The quenching device of the invention comprises a base seat, columns fixedly connected at both sides of the base seat and a 'door'-shaped lathe bed formed by fixed beams which are fixedly installed at the tops of two columns. A lower quenching mould is installed on a box-typed worktableand a telescopic oil shield and an upper mould matched with the lower mould are installed under a moving beam. The quenching device of the invention is characterized in that the base seat and the guide rail of the worktable are placed in an oil groove; an oil intake port and an oil return port are installed on the oil groove at one side of the base seat; the oil intake port is matched with an oilinlet on the box-typed worktable; vertical guide rails are installed on the columns at both sides of the base seat; the upper mould installed in the telescopic oil shield is connected with a mould cylinder installed on the moving beam and a moving beam locking device is installed between the moving beam and the fixed beam. The quenching device of the invention can satisfy the quenching process with full-size trap parts, namely, the trap parts with different specifications, and is characterized by wide application scope.

Description

technical field [0001] The invention relates to a heat treatment device, in particular to a quenching device for full-scale snare parts. Background technique [0002] Due to the thin wall thickness of the snare parts, it is very easy to deform during the quenching process, resulting in a high rejection rate, especially in the extra large bearing processing industry, this problem is particularly prominent. In order to solve the problem of large quenching distortion and serious shrinkage of carburized bearing steel, people have done a lot of work, such as the inventor applied for "Railway Bearing Inner and Outer Ring Quenching Process and Quenching Press" on April 10, 2006, The patent application number is 200610076933.4. The equipment includes a base, two columns fixed on the base and a beam installed on the column. The lower mold is installed on the movable box-type workbench, and the movable beam that can move up and down is installed. There is an upper mold and a cooling ...
