Description
Technical field
The present invention relates to equipment manufacturing technology field, especially a kind of screw compressor STR Moving plate hot forged moulds.
Background technology
In the prior art pair with STR Moving plate manufacturing processes, because the structure of its Moving plate is special, in forging process easily
There is situations such as local forging molding is not in place, the particularly outer end of the helical structure of Moving plate, it is often because be vented not
Freely cause Moving plate that local defect occurs in this place, so as to cause whole Moving plate to scrap.
The content of the invention
There is provided a kind of simple in construction the invention aims to solve the deficiency of above-mentioned technology, can ensure that STR Moving plates
Forging molding is stable, the screw compressor STR Moving plate hot forged moulds of high yield rate.
In order to achieve the above object, a kind of screw compressor STR Moving plate hot forged moulds designed by the present invention, it includes upper
Die holder, die shoe, are provided with punch-pin on upper bolster, are provided with die shoe on cavity plate, described cavity plate and are provided with spiral
Shape cavity, the die cavity that cavity plate is formed after coordinating with punch-pin is consistent with STR Moving plate shapes；On the bottom surface of the spiral shape cavity of cavity plate
What is be spaced is provided with jogger hole, and described jogger hole is arc-shaped structure, its radian and the spiral shape cavity at position
Radian is consistent；Jogger hole is again provided with the bottom surface of the medial end of spiral shape cavity；In the outboard end of spiral shape cavity
Be provided with six steam vents on the bottom surface in portion, the aperture of described steam vent is less than the width of spiral shape cavity, in upper bolster and
Two or many controllable heating rods are respectively arranged with die shoe, temperature sensor is respectively arranged with upper bolster, die shoe.
The design of above-mentioned technical proposal, by being arranged at intervals jogger hole on the bottom surface of the spiral shape cavity of cavity plate, in forging
Jogger hole its die cavity can be exhausted as steam vent during making, so that it is guaranteed that in forging process product stability.Together
When steam vent is set on the bottom surface of spiral shape cavity outboard end, the design of the steam vent can be in forging process by spiral
The air of shape cavity end is thoroughly discharged, so that realize that the integrality and quality of the lower end outside end of STR Moving plates are guaranteed,
Will not camber line local defect situations such as.
As optimization, the aperture of described steam vent is 1mm.The design of the structure, both may insure to mould chamber air
Discharge, and ensure the intensity and stability of mould.Because in forging process, the stress of the end of spiral shape cavity is maximum,
According to push rod well format, cause the insufficient strength at this and just damaged after multiple forging, and be vented setting for bore dia 1mm
Meter, can discharge air, and ensure that certain pressure can be produced at this in forging process, and the bearing capacity and intensity at this are more
By force.
Water-based graphite is soaked on blank in forging process, releasing agent is sprayed on punch-pin and cavity plate.The structure is due to STR
Moving plate it is complicated, its contact area between mould is big, so needing smearing release agent and coordinating top in jogger hole
Rod aperture is stripped, it is ensured that the demoulding is smooth.
Material selected by described punch-pin, cavity plate pulls out material for the upsetting three of electroslag remelting three.Punch-pin, the surface of cavity plate pass through
Physical vaporous deposition processing.Above-mentioned processing procedure can effectively improve the hardness and rub proofness of mould so that mould is used
Life-span is longer.
A kind of screw compressor STR Moving plate hot forged moulds obtained by the present invention, by rational structure design, can be realized
Hot forging to STR Moving plates, and stability is high in hot forging process, the yield rate of product quality and product is got a promotion.
Brief description of the drawings
Fig. 1 is structure sectional view of the invention；
Fig. 2 is the die shoe of the present invention and the structural representation of cavity plate.
