Abstract

The invention provides a vacuum multi-purpose furnace, which belongs to the technical field of heat treatment. The vacuum multi-purpose furnace comprises a quenching furnace shell, an inner furnace shell and a carburizing furnace shell, wherein the quenching furnace shell is connected with the carburizing furnace shell by virtue of the inner furnace shell, an outer furnace door is arranged at an opening of the quenching furnace shell, material inlet and outlet tracks are arranged in the quenching furnace shell and the carburizing furnace shell, a push-pull machine and a lifting platform which are used for feeding and discharging materials are arranged in the quenching furnace shell, the push-pull machine and the lifting platform are crossed, a first motor is arranged on the top of the quenching furnace shell, the first motor is connected with a fan, a lifting inner furnace door, a door frame, a compensation track assembly and a pressing assembly are arranged in the inner furnace shell, the door frame can be pressed on the inner furnace shell by the pressing assembly, the inner furnace door can move along the door frame, the compensation track assembly is lifted along with the inner furnace door, a heater is arranged at the bottom of the quenching furnace shell, an internal furnace is arranged in the carburizing furnace shell, a plurality of electric radiation heating pipes are arranged in the carburizing furnace shell, and vacuum nitrogen charging units are respectively connected to the quenching furnace shell and the carburizing furnace shell. The vacuum multi-purpose furnace has the advantage of high degree of automation, and the efficiency of heat treatment is improved.

Description

technical field [0001] The invention relates to a heat treatment furnace, in particular to a vacuum furnace. Background technique [0002] In the prior art, the vacuum furnace includes a furnace shell, and the furnace shell is equipped with an inlet and outlet track. The workpiece cannot be fed during heat treatment. The workpiece must be taken out after the heat treatment is completed and the workpiece is cooled. The material tray with the workpiece is pushed to the heat treatment station along the feeding and discharging track. The vacuum furnace can only realize one heat treatment process, the continuity and automation of the work are poor, and the heat treatment efficiency is low. Contents of the invention [0003] Aiming at the defects in the prior art, the purpose of the present invention is to overcome the deficiencies in the above-mentioned prior art, and provide a vacuum multi-purpose furnace, which integrates multi-functional work, can also feed materials during ...
