Problems solved by technology

However, this structure has disadvantages such as the intermediate transition chamber being too long, the heating speed of the vacuum heating chamber being slow, and the furnace temperature being uneven. In addition, the entire oil tank needs to be held up when the seal is docked, and the structure is heavy.
This structure is not suitable for the pre-evacuation and protective atmosphere heat treatment furnace production line that requires convection heating

Abstract

A sealed workpiece transferring system for a vertical heat treating line is composed of the protecting atmosphere system and vacuum system, which are respectively coupled with the upper and lower parts of heating furnace and the preheating furnace, an insulating vacuum sealing valve, movable sealing hood linked with its lift mechanism, the preheating furnace, furnace cover and quenching bath, which are arranged on a small train, and relative sealing rings.

Description

technical field [0001] The invention relates to a device used in the technical field of metal heat treatment, in particular, a workpiece seal transfer device for a vertical heat treatment production line. Background technique [0002] The pre-evacuated protective atmosphere furnaces currently used in factories include well type, horizontal type, double chamber and pusher type continuous type, etc., which are respectively suitable for bright quenching, bright tempering and bright annealing of workpieces for different purposes. However, most of them are fixed and single-purpose furnaces. The furnace has poor scalability, poor production flexibility, low production efficiency, and is not suitable for heat treatment of large shaft and cylinder parts. In order to make the pre-vacuum plus protective atmosphere furnace have a wider application field, improve its production flexibility and improve production efficiency, it is necessary to combine different types of pre-vacuum plus p...
