Equipment for achieving regional sintering

Abstract

The invention discloses equipment for achieving regional sintering. The equipment comprises a regional sintering furnace and a mechanical transmission device for achieving downward movement of blanks. The regional sintering furnace comprises a furnace shell, a furnace opening which is formed in the furnace shell and serves as a feeding opening, a thermal insulation material arranged on the side wall and the top wall of the furnace shell, a furnace pipe which communicates with the furnace opening and is surrounded by the thermal insulation material, heating elements arranged on the outer side wall of the furnace pipe, a water cooling device for cooling the furnace pipe and a temperature control system for controlling the temperature of the furnace pipe. The mechanical transmission device comprises an ejector rod arranged in the furnace pipe 7, rolling wheels mechanically connected with the ejector rod, a rolling wheel bearing seat mechanically connected with the ejector rod, a motor for providing kinetic energy for the rolling wheels and the rolling wheel bearing seat, a speed governor for controlling the motor, a chain for transmitting the kinetic energy output by the motor to the rolling wheels and the rolling wheel bearing seat and a reducer for decelerating the chain.

Description

technical field [0001] The invention relates to the technical field of sintering, in particular to a device for realizing regional sintering. Background technique [0002] At present, the current sintering process is to place the whole sintered billet in a hydrogen-protected sintering furnace for sintering, especially when producing one-dimensional large-size products. Green body; the one-dimensional size of cold isostatic pressing is limited; although metal injection molding and metal extrusion molding are not limited in one-dimensional size, the degreasing process is complex, time-consuming and difficult to control. Most importantly, due to the influence of the gravitational field, the sintered compact is prone to deformation and difficult to control during the sintering process of liquid phase sintering. In this way, the production of one-dimensional large-size products is limited by the influence of billet making and sintering processes, high equipment investment costs,...
