Abstract
The invention includes a retort furnace and an evacuation part. The retort furnace comprises a furnace body and a heating chamber disposed in the furnace body. Six lead-out electrodes are mounted on the retort furnace. The upper and lower beams of a hydraulic oil press disposed on the top and at the bottom of the furnace body separately are integrated four columns. An upper pressure head consists of an upper water-cooled pressure head and an upper graphite pressure head. A lower pressure head consists of a lower water-cooled pressure head and a lower graphite pressure head.
Description
(1) technical field
The present invention relates to a kind of vacuum heating-press sintering stove, be specifically related to a kind of two-way heat pressing type vacuum heating-press sintering stove.
(2) background technology
The vacuum heating-press sintering stove is that vacuum, molded, the high temperature sintering of pad are combined, and is widely used in the sinter molding of various anti-oxidation materials, and known vacuum heating-press sintering stove is the uniaxial hot pressing moulding at present, and the hyperthermia radiation baffle plate is positioned at the body of heater outside.This vacuum heating-press sintering stove production efficiency is lower, extrudate density is little, and heating clamber is short service life.
(3) summary of the invention
Purpose of the present invention provides a kind of production efficiency height, good product quality, vacuum one hot-pressed sintering furnace of heater long service life.
The technical scheme that adopts is:
Vacuum one hot-pressed sintering furnace comprises sintering furnace, seaming chuck, push-down head, upper cylinder, following oil cylinder and vacuumized part.Supporting device with upper and lower oil cylinder is a twin beams four-column type structure, and upper cylinder and following oil cylinder are installed in respectively on upper beam and the underbeam.Upper cylinder is connected with load sensor by flange, and the load sensor lower end is connected with water-cooled pressure head flange.Water-cooled pressure head lower end is connected with last graphite pressure head.Following oil cylinder is connected with following water-cooled pressure head by flange, and following water-cooled pressure head is connected with following graphite pressure head.Sintering furnace by a plurality of stent support on the upper surface of underbeam.Sintering furnace comprises that body of heater, cylindrical shape heating clamber, six draw electrode and aerating device.On bottom of heating chamber, be provided with mould rack.Mould is arranged on the mould rack.The cylindrical shape heating clamber is arranged in the body of heater, is supported by a plurality of heating clamber supports, offers the pressure head through hole symmetrically on the upper and lower end face of body of heater and heating clamber.Upper and lower graphite pressure head passes the pressure head through hole on the heating clamber respectively.Six groups draw electrode respectively the electrode through hole on body of heater and the heating clamber insert in the body of heater.Draw at six groups and to be equiped with heat radiation on the electrode respectively and to block ring, baffle plate is positioned at heating clamber.Six groups are drawn electrode and are connected with graphite heater by water cooled electrode respectively.Fire door and heating clamber door are connected to an overall structure.Fire door props up column articulated by connecting rod with a corresponding hydraulic press.
The present invention has improved production efficiency owing to adopted two-way hot pressing, has shortened the goods manufacturing cycle, increases substantially the density of product, and has realized the hot pressing demoulding of goods.Owing in heating clamber, increased the heat radiation shutter, improved hot pressing temperature, avoided high temperature to drawing the hyperthermia radiation effect of electric electrode insulation ring, improved service life.In addition, to the damage of electrode insulation, insulating properties have been improved when also having reduced high temperature hot pressing.
