Abstract
A backpressure forming mold structure relates to molds for plastic processing of vortex discs by means of backpressure forming in the metal pressure working industry, consists of a lower ejector rod 27, a disc spring 28, a guide sleeve 29, a spring backing plate 30 and an ejector supporting plate 31, and replaces a hydraulic system of the patent ' A backpressure forming mold structure for vortex discs of vortex compressors' with the number of ZL200320100429.5 (hereafter referred as the patent I ). Elasticity of the disc spring of the mold structure provides back pressure for backpressure forming of vortex discs, and a piston in an ejector cylinder of a press provides ejecting force to eject formed part out of a die.
Description
Technical field
The utility model relates in the stress metal processing industry, the mould structure that scroll compressor scroll (hereinafter to be referred as scroll) is carried out plastic working with the counterpressure forming method.
Background technology
Scroll is the main element of swirl type cold compressor compression cooling medium.Because the type compression mechanism cold efficiency is very high, obtaining promoting and extensive use.Accompanying drawing 1 is a kind of typical scroll part master drawing.Can find out that by Fig. 1 the one side at disk is the linear convexity of vortex; Another side is an annular projection; According to the rule and the practice of Metal Forming, the linear convexity of its vortex short transverse in forming process can produce bigger difference in height, and difficulty not only is shaped; Waste material, and cause very big trouble for follow-up fine finishining.Have high, good, the stock utilization advantages of higher of quality of precision of drip molding with counterpressure forming method production scroll, become the development trend that scroll is made in industrialization.At present, for providing back pressure, counterpressure forming mainly contains three kinds of forms: (1) spring; (2) nitrogen cylinder; (3) hydraulic system.
Facts have proved that the above-mentioned form of back pressure that provides may be used to produce, and pluses and minuses are respectively arranged.Provide back pressure to have advantages such as mould structure is simple, cost is low with form (1).Its shortcoming is a back pressure adjustment difficulty, is not suitable for the production of many kinds scroll; Provide back pressure to use with form (2) and change the blowing pressure adjustment back pressure, but under the hot forming working environment, the sealing ring life-span of nitrogen cylinder is low; Provide back pressure to have advantages such as pressure stability, pressure regulation convenience with form (3), shortcoming is that mould structure is complicated, and cost is high.According to producing actual needs, simplify mould structure, reduce cost, be a job highly significant.Especially in the commercial production few in product specification, that batch is big, with form (1) back pressure being provided is a kind of selection preferably.
Summary of the invention
The purpose of the utility model is for a kind of simple in structure, practical, counterpressure forming mould structure that cost is low is provided, to satisfy the requirement of scroll counterpressure forming.
To achieve these goals; The technical scheme that the utility model adopted is: adopt the back pressure mould structure of being made up of lower push rod (27), disk spring (28), fairlead (29), spring backing plate (30) and push rod supporting plate (31), provide counterpressure forming needed back pressure.When counterpressure forming; Elastic force when metal material mobile promotion vortex (11) is compressed by disk spring (28) provides back pressure; The elasticity of compression power of disk spring (28) and stroke only need be changed corresponding butterfly spring and can realize different back pressures according to the design of scroll counterpressure forming technological requirement when producing the forging of different size.Because the required back pressure of scroll counterpressure forming is that the elasticity of compression power of disk spring (28) is less than the required kicking force of counterpressure forming; Therefore be shaped and finish the back forging and rest on die (10) lining, through lower push rod (27), push rod supporting plate (31), ejector beam (9) and vortex (11) it is ejected with the piston that ejects in the oil cylinder of forcing press.
Relatively the utility model (Fig. 3) and patent 1 (Fig. 2) can be found out; The utility model has removed vent valve (25) and oil connection (26) and the corresponding seal in the patent 1; Replace hydraulic system with disk spring (28) back pressure is provided; Simplify mould structure, reduced production unstability unstable because of hydraulic system, that leakiness wet goods shortcoming causes, more can adapt to bad working environments such as high temperature under the hot forming working environment, lubricating fluid.Replace lower piston (24) with spring bearer plate (30),, simplified mould structure with fairlead (29) displace oil cylinder sleeve spare (7).Lower push rod (27) with larger diameter replaces lower push rod (3), has improved the stationarity of head part.
Description of drawings
Existing following to the description of drawings of the utility model:
Fig. 1 is the scroll part drawing.Among the figure, Fig. 1 a is a front view, and Fig. 1 b is a left view, and Fig. 1 c is a graphics.
Fig. 2 is the counterpressure forming die structure dwg of patent 1.Among the figure, 1. die shoe, 2. lower cushion block, 3. lower push rod, 4. adjustment piece, 5. limited block, 6. push rod supporting plate; 7. oil cylinder cover, 8.H shape die holder, 9. ejector beam, 10. die, 11. vortexes, 12. die nuts, 13. punch retainers; 14. convex mould base, 15. upper bolsters, cushion block on 16., 17. upper ejector pins, 18. transiting rods, 19. punch cushion blocks, 20. punch; 21. guide pin bushing, ejector beam on 22., 23. guide pillars, 24. lower pistons, 25. vent valves, 26. oil connections.
Fig. 3 is the counterpressure forming die structure dwg of the utility model.Among the figure, 27. lower push rods, 28. disk springs, 29. fairleads, 30. spring backing plates, 31. push rod supporting plates.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
Embodiment one:
A kind of counterpressure forming mould structure is as shown in Figure 3:
This mould structure is that (seeing Fig. 2 for details) improves original mould structure on the basis of the counterpressure forming mould structure of patent 1; With the hydraulic system of disk spring structure replacement patent 1, use the hydraulic coupling of elastic force replacement patent 1 hydraulic system of disk spring back pressure to be provided as the scroll counterpressure forming.
When counterpressure forming began, disk spring (28) was in stretched condition, and spring backing plate (30), push rod supporting plate (31) and lower push rod (27) are in the top dead-centre position; When counterpressure forming carried out, spring backing plate (30) and push rod supporting plate (31) were descending in the effect of ejector beam (9) and vortex (11), and compression disk spring (28) makes it to produce elastic force.This elastic force acts on the scroll counterpressure forming spare as back pressure; When counterpressure forming finishes; Because the required back pressure of scroll counterpressure forming; The elasticity of compression power that is disk spring (28) is less than the required kicking force of counterpressure forming; Therefore drip molding rests in the die (10), it is ejected through lower push rod (27), push rod supporting plate (31), ejector beam (9) and vortex (11) with the piston that ejects in the oil cylinder of forcing press.Spring backing plate (30) and lower push rod (27) are got back to the top dead-centre position under the effect of disk spring (28).
Put into new counterpressure forming spare blank, begin next operation cycle.
