Abstract
A vacuum ion hot pressing furnace comprises a furnace body, a furnace cover, an upper and a lower water cooling press head, an upper and a lower electricity feed water cooling electrode, a vacuum system and an electric control unit, which is characterized in that a plasma power supply is provided outside the furnace body, whose output end is connected with the upper and lower electricity feed water cooling electrodes via wires. The vacuum ion hot pressing furnace has the advantages of high heating speed, high heat transmission speed, fast sintering or hot pressing temperature increase, and short time, thus being beneficial for hot pressing or sintering at lower temperature, to be applied under low hot pressing and sintering temperature, with low cost.
Description
Technical field
The utility model belongs to vacuum hotpressing stove, particularly a kind of vacuum ionic hot pressing furnace.
Background technology
Conventional vacuum hotpressing stove is by body of heater, vacuum system, press, electrical control cubicles, upper and lowerly advance electric water cooled electrode, upper and lower water-cooled pressure head is placed on the felt pad between water cooled electrode and the water-cooled pressure head, be installed in heating resistor or eddy-current heating body and heat-insulation layer formation in the body of heater, it adopts heating resistor or Frequency Induction Heating.Adopt resistance heated, heating-up temperature is low, during as if the high temperature heating, and insulating part cost height, resistance heated need have heat-insulation layer, the heat-insulation layer accumulation of heat, the thermal efficiency is low, wastes energy.Adopt Frequency Induction Heating, during heating heat-insulation layer need be arranged, the heat-insulation layer accumulation of heat, the thermal efficiency is low, power supply cost height.
Summary of the invention
The purpose of this utility model is to solve the problems referred to above that prior art exists, provide a kind of heating fast, conduct heat soon, sintering or hot pressing quick heating, time are short, help at lower temperature hot pressing or sintering, hot pressing, sintering temperature are low, the vacuum ionic hot pressing furnace that cost is low.
The utility model be achieved in that it comprise body of heater, bell, up and down the water-cooled pressure head, advance electric water cooled electrode, vacuum system, ECU up and down, its special character is: be provided with plasma power supply in body of heater outside, described plasma electric source output terminal advances electric water cooled electrode and is connected with upper and lower by lead.
The beneficial effects of the utility model:
(1) because plasma power supply directly heats test specimen or mould, heating is fast, it is fast to conduct heat, so sintering or hot pressing quick heating, time short (about general 10min);
When (2) having minimum gap between sample particle, because the existence of pulse voltage, instantaneous generation highfield, puncture the gap and produce electric discharge phenomena, Pulsed Discharge shock wave and electronics, ion reciprocal constant speed in electric field flows, make that powder purifies, activation, help, than low 100 ℃～200 ℃ of hot pressing, the sintering of routine at lower temperature hot pressing or sintering.
(3) can obtain tiny uniform formation, the material of high-compactness.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
As shown in the figure, the utility model has a press 9 that body of heater 1 is installed on press 9, fire door 2 is installed on body of heater 1, last water-cooled pressure head 6, following water-cooled pressure head 7, last water-cooled pressure head 6, following water-cooled pressure head 7 links with press 9, outside body of heater 1, be provided with the vacuum system 8 that links to each other with body of heater 1, on in body of heater 1, also being provided with, under enter electric water cooled electrode 5 and 4, outside body of heater 1, be provided with ECU 11 and plasma power supply 10, described ECU 11 is connected with the input of plasma power supply 10, and the output of plasma power supply 10 is by lead and last, under advance electric water cooled electrode 5 and be connected with 4.
During work, sample or mould are placed on upper and lowerly to advance between the electric water cooled electrode 5 and 4, between water cooled electrode and the water-cooled pressure head felt pad 3 is arranged, putting pass, back fire door 2 well vacuumizes, when vacuum reaches requirement, start plasma power supply 10, the workpiece heating is fast, when reaching the temperature of hot pressing workpieces or sintering, start press 9 compactings.
