Self-cleaning box type quenching furnace for part machining

Abstract

The invention discloses a self-cleaning box type quenching furnace for part machining, which belongs to the technical field of quenching furnaces. The self-cleaning box type quenching furnace for partmachining comprises a furnace body, wherein a furnace door is arranged on the left side of the front end of the furnace body; a microcomputer control device is arranged on the right side of the furnace body; a furnace pipe is arranged in the furnace body; a circuit layer is arranged on the outer wall of the furnace pipe; a heating chamber is arranged at the top part of an inner cavity of the furnace pipe; a resistance tape is arranged on the inner wall of the heating chamber; a supporting plate is arranged at the bottom part of the heating chamber; threaded rods are inserted into the left andright sides of the top part of the supporting plate respectively; U-shaped sliding grooves are formed in the left and right sides of the bottom part of the supporting plate respectively; a filteringdevice is slidably connected into each U-shaped sliding groove; a quenching liquid groove is formed in the bottom part of the supporting plate; and a liquid outlet is formed in the left side of the bottom part of the quenching liquid groove. According to the self-cleaning box type quenching furnace for part machining, a circuit layer is cleaned by means of a draught fan, manpower is saved; and meanwhile, a quenching liquid can be used repeatedly by means of the filtering device, thus a large amount of quenching liquid is saved.

Description

Technical field [0001] The invention relates to the technical field of quenching furnaces, in particular to a self-cleaning box-type quenching furnace for parts processing. Background technique [0002] The traditional quenching furnace requires frequent replacement of the quenching liquid, which wastes a lot of time and wastes a lot of quenching liquid. Moreover, the internal heating device is unreasonably designed, and the heating is uneven, which affects the quality of processing. The circuit layer needs manpower to clean regularly, which is time-consuming. Therefore, we propose a self-cleaning box quenching furnace for parts processing. Summary of the invention [0003] The purpose of the present invention is to provide a self-cleaning box-type quenching furnace for parts processing to solve the problems raised in the background art. [0004] To achieve the above objective, the present invention provides the following technical solution: a self-cleaning box-type quenching furna...
