Background technology
At present, in the processing procedure of heat pipe product, need to import different atmosphere gas sintering in atmosphere furnace, sintering is a considerable process, because sintering process is directly connected to the quality of heat pipe product quality, in the manufacturing process of sintering, its key is the control of sintering temperature, satisfy the even of product by heating, avoid producing inferior goods.Present atmosphere furnace is owing to temperature control instability in the stove, cause the sintered products fraction defective higher easily.Applicant of the present utility model once disclosed " a kind of atmosphere furnace structural improvement " of utility model patent numbers 173125 in TaiWan, China, this patent mainly is to be provided with body of heater, siege, heat generating component and electrical control gear in atmosphere furnace, assembly to be sintered is placed on the siege, and import atmosphere gas and assembly sintering to be sintered is finished.This structure is characterised in that: the atmosphere furnace furnace bottom has rotation apparatus makes the siege rotation, the body of heater lower end then has gas clamping plate, and the siege outside is provided with the groove of top end opening and constitutes the big envelope device with respect to place, gas clamping plate below, be equipped with seal in this big envelope device groove, assembly to be sintered places on the siege rotation with siege to rotate, and the sealing of big envelope device, make and block gas leak and heat more even.This patent mainly is to utilize the rotation apparatus of being located at the atmosphere furnace furnace bottom to make the siege rotation, and makes heating more even.On practice, also can reach the function of expection really.Yet the way of rotation apparatus is set in atmosphere furnace, increased the manufacturing cost of atmosphere furnace in vain, in addition, because the capillary structure of heat pipe inboard wall of tube body face is to make (being generally copper powder) with thermal conductivity good metal material sintering, and this copper powder is before sintering, manufacturer is for preventing oxidization of copper powder, can when producing copper powder, add antioxidant, make the copper powder surface form one deck oxidation-resistant film, also remaining between copper powder and copper powder in addition have oxygen, and remaining oxygen between the lip-deep oxide-film of copper powder and copper powder and copper powder, in atmosphere furnace during with atmosphere gas positive air pressure sintering, often degreasing is discharged fully, and this situation is that obviously this quality for heat pipe has harmful effect certainly more when heat pipe length is long more.This also is that prior art exists maximum defective, and this defective is the technical barrier that industry needs to be resolved hurrily.
The utility model content
In view of this, main purpose of the present utility model is to provide a kind of atmosphere furnace that has better equal thermal effect and can carry out heating in vacuum, improves the quality of products.
For achieving the above object, the technical solution of the utility model is achieved in that a kind of lift vacuum atmosphere oven, it comprises body of heater and lift siege, this body of heater has and is installed with the lift siege between the thermal capacitance of adding, add that the edge also is provided with heater between thermal capacitance, this siege lower end is provided with thermal insulation layer, siege and thermal insulation layer outer fringe seal are provided with inner furnace body, inner furnace body has heating space, air inlet pipe and escape pipe, the siege bottom is provided with lowering or hoisting gear, it is characterized in that: be provided with inner heating device in the above-mentioned inner furnace body heating space.
As a kind of improvement, above-mentioned escape pipe can be connected with vacuum extractor, cooperates to close air inlet pipe, and the inner furnace body heating space is vacuumized; And, can also have the turnover tracheae in the inner heating device, connect this vacuum extractor.
Improve as another kind, can be provided with the turnover tracheae in the above-mentioned inner heating device, connect the inlet, outlet device.
The utlity model has following advantage:
1. be provided with inner heating device in the inner furnace body heating space of the present utility model, make the easier effect of reaching soaking in the stove of heating space in the inner furnace body, and do not need to see through the inner furnace body indirect, can effectively promote the quality of heat pipe sintering.
2. escape pipe of the present utility model can be connected with vacuum extractor, closing air inlet pipe with cooperation vacuumizes the inner furnace body heating space, realize heating in vacuum, with in the heat pipe between the lip-deep oxide-film of copper powder to be sintered and copper powder and copper powder remaining oxygen under vacuum environment, realize heating in vacuum degreasing program, and discharge fully, close vacuum extractor this moment, import atmosphere gas and carry out malleation atmosphere sintering program, the heat pipe that sintering is finished, because oxygen remaining between the lip-deep oxide-film of copper powder and copper powder and copper powder is discharged when vacuum-sintering fully, so can effectively promote the quality of heat pipe sintering.
