Fully automatic multi-station rotary ferrule parts molding quenching press

Abstract

The invention relates to a heat treatment quenching device, in particular to a fully-automatic multi-station rotary type die-quenching press machine for a ferrule type part. The die-quenching press machine comprises an annular rotary working platform, an independent quenching unit and an annular oil-quenching tank, wherein the quenching unit is fixed on the annular rotary working platform; and oil-spraying and quenching of inner and outer walls of the quenched ferrule type part are performed by quenching cooling oil through a rotary distribution valve and two oil outlets in the rotary distribution valve. According to the technical scheme of the fully-automatic multi-station rotary type die-quenching press machine, the structure is unique; a continuous automatic quenching function can be realized; at the same time, fully-automatic control of feeding, quenching and discharging of a workpiece is realized; the quenching quality is high, the operation is simple, and the labor intensity is low; a quenching process of the quenched ferrule type part is completed in the annular oil-quenching tank; a part of mechanisms are immersed in the cooling oil; the environment is clean; fire catching is avoided easily during quenching, little oil smoke exists, and environmental protection is facilitated.

Description

technical field [0001] The invention relates to a heat treatment and quenching device, in particular to a full-automatic multi-station rotary ferrule-type parts molding and quenching press. Background technique [0002] Ring parts are easy to deform due to their thin walls during quenching, which increases the machining allowance after quenching, especially for the quenching of the inner and outer rings of the bearing. When the deformation is too large, the machining allowance after quenching increases. The hardness and metallographic structure of the surface of the inner and outer rings of the bearing do not meet the requirements. In order to solve the problems of uncontrollable quenching process of ferrule parts, irregular deformation and rework and high scrap rate, people have done a lot of work, such as the utility model patent ZL200420086806.9 "A Multi-station Bearing" published by the Chinese Patent Office Quenching Press for Inner and Outer Rings" designed a multi-st...

When the deformation is too large, the machining allowance after quenching increases. Large, resulting in the surface hardness and metallographic structure of the inner and outer rings of the bearing not meeting the requirements

In order to solve the problems of uncontrollable quenching process of ferrule parts, irregular deformation and rework and high scrap rate, people have done a lot of work, such as the utility model patent ZL200420086806.9 "A Multi-station Bearing" published by the Chinese Patent Office Quenching Press for Inner and Outer Rings" designed a multi-station quenching press that uses upper and lower molds to limit the deformation of the workpiece to be quenched. On the one hand, it solved the problem of quenching deformation of the bearing ring, and on the other hand, it improved the workpiece. Quenching efficiency
