Reaction furnace used for automobile die hot-working process

Abstract

The invention discloses a reaction furnace used for an automobile die hot-working process. The reaction furnace used for the automobile die hot-working process comprises a furnace body, a transformer and a furnace door. The furnace door is arranged on the front side of the furnace body. A fixing shoulder which horizontally protrudes towards the two sides is arranged at the top end of the furnace door. According to the reaction furnace used for the automobile die hot-working process, a rotary shaft, driven rollers, a driving roller and a power device are arranged for opening and closing of the furnace door, efficiency is high, and stability is guaranteed; the power device of the reaction furnace intelligently controls the rotating speed of a motor by combining a voltage comparator and a triode, and compared with a traditional way that the working voltage of the motor is changed directly, the stability is higher, shaking of the motor is reduced, and the rotating speed can be displayed visually; and by arranging buffering rods which are located in a cylinder and connected with the fixing shoulder, impact force exerted on the furnace body when the furnace door descends is effectively reduced, the situation that a die subjected to hot-working in the furnace body moves due to shaking and deviates from a machining station is avoided, damage to the whole reaction furnace is reduced, and the service life of the reaction furnace is prolonged.

Description

technical field [0001] The invention relates to the field of automobile mold production equipment, in particular to a reaction furnace for thermal processing technology of automobile molds. Background technique [0002] The most important part of the automobile mold is the cover mold. This type of mold is mainly a cold stamping mold. In a broad sense, "automotive mold" is the general term for molds that manufacture all parts on automobiles. [0003] Mold heat treatment is an important process to ensure the performance of the mold, which directly affects the manufacturing accuracy, strength, working life, etc. of the mold. The heat treatment furnace is the key device for this process. [0004] Because the heat treatment furnaces of existing enterprises need to process products in batches, the specifications are relatively large, and they also need large and heavy furnace doors. The workpiece to be processed is displaced and deviates from the processing station, which affec...

[0004] Because the heat treatment furnaces of existing enterprises need to process products in batches, the specifications are relatively large, and they also need large and heavy furnace doors. The workpiece to be processed is displaced and deviates from the processing station, which affects the processing effect, and the long-term vibration will affect the service life of the equipment
