In the die, a hydraulic circuit formed by a relief valve (33), a two-position two-way valve (34) and a pressure meter (35) is additionally arranged in an original downward ejection hydraulic system of a pressure machine, so that the system keeps the original ejection function, and also has the backpressure supplying function , and the die structure of a patent 'backpressure forming die structure for scroll of scroll type refrigeration compressor ZL03245066.4' is simplified.
Description
Technical field
The utility model relates to a kind of in the stress metal processing industry, the mould that vortex compressor of air conditioner 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.The precision that has drip molding with counterpressure forming method production scroll is high, and the metallographic structure quality is good, and the stock utilization advantages of higher has become the development trend of making scroll.For counterpressure forming provides back pressure various ways is arranged: (1) spring; (2) nitrogen cylinder; (3) hydraulic system.
Facts have proved, 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.Improvement provides the mould structure of back pressure with the hydraulic pressure form, simplifies mould structure, reduces cost, is a job highly significant.
Summary of the invention
The purpose of the utility model is in order the counterpressure forming that a kind of structure is simple relatively, practical, cost is lower mould to be provided, can to satisfy the requirement of scroll counterpressure forming.
To achieve these goals, the utility model is through utility model patent " the counterpressure forming mould structure ZL03245066.4 of a kind of vortex type refrigeration compressor-spiral dish " (hereinafter to be referred as patent 1) is improved realization.Relatively the utility model (Fig. 3) and patent 1 (Fig. 2) can be found out; The utility model has removed part 4, part 24 and part 25 and the corresponding seal in the patent 1; The following ejection system own with forcing press replaces the hydraulic system in patent 1 mould structure, for the scroll counterpressure forming back pressure is provided by the lower piston (2) that ejects in piston (36) the replacement patent 1 that ejects down in the oil cylinder.
Usually the function of the following ejecting mechanism of forcing press is after accomplishing metal forming; Eject from die through ejecting the drip molding that piston (36) will be present in the mould die; After drip molding takes out; Eject piston (36) and return original position, in die, put into new drip molding blank, begin next operation cycle.
In spiral dish counterpressure forming process, need provide a back pressure could guarantee the forming requirements of spiral dish.To eject piston (36) back pressure can be provided in order to make, require to eject piston (36) and after accomplishing ejection stroke, remain on this position, in spiral dish counterpressure forming process, continue to provide back pressure, accomplish up to forming process to the spiral dish.Eject piston (36) workpiece is ejected, accomplish an operation cycle.
Because back pressure is less than ejecting force, the utility model is transformed the original hydraulic system of forcing press.Increased the loop that back pressure is provided that overflow valve (33), two position two-way valve (34) and Pressure gauge (35) are formed.When two position two-way valve (34) when closing, three-position four-way valve (29) is in position, a left side, ejects piston (36) and is in the state of ejecting.When three-position four-way valve (29) is in right position, eject piston (36) and be in the backhaul state.When three-position four-way valve (29) is in meta, it is slack to eject piston (36).System pressure is controlled, is shown by Pressure gauge (30) by overflow valve (31); When three-position four-way valve (29) is in meta, two position two-way valve (34) ejects piston (36) and is in the back pressure state when opening.System pressure is controlled, is shown by Pressure gauge (30) by overflow valve (31).In the counterpressure forming process, eject piston (36) and back pressure and ejecting force are provided through regulating block (26), lower push rod (27) and cushion block (28).Through the utility model the original hydraulic system of forcing press is improved, made it both to have kept ejecting function under original, increased the function that back pressure is provided for spiral dish counterpressure forming again, simplified the mould structure of patent 1.
