Abstract
The utility model discloses a stealthily defile pump pump case forming die belongs to latent dirty pump pump case and makes technical field. A stealthily defile pump pump case forming die includes terrace die and die, the surface of terrace die and the stealthily dirty pump pump case internal surface cooperation that coincide, the die is inside to have a sunken inner chamber, and the internal surface of die inner chamber coincide with latent dirty pump pump case surface and cooperates. Push latent half finished product top of dirty pump pump case and lower part respectively through terrace die and die, the shaping of expanding half finished product top forces down in the terrace die outside, half finished product is partial down to shrink the shaping under the external pressure of die. The utility model discloses utilize the mould to enable half finished product and go up to expand and contract down, through last expand to contract down accompany the upper and lower process of metal flow hydraulic pressure, messenger moulded product's wall thickness is unanimous basically, the error control of wall thickness is at 0.2mm. A bloated forming process that contracts, the extrusion volume is less relatively, and the mould also is difficult for pulling, has gained fine manufacturability and economic nature.
Description
Technical field
The utility model relates to a kind of submersible sewage pump pump case moulding mould, belongs to submersible sewage pump pump case manufacturing technology field.
Background technology
The submersible sewage pump pump case of prior art normally adopts casting to add machined and forms, the steel plate that specifically used thickness is 2mm is raw material, employing casting adds machine deep drawn mold forming, the pump case product wall unevenness that this deep drawn mold forming method is produced is even, pump case size cannot accurately be controlled, and causes shell molding effect poor. And this forming method is not only lost time but also waste energy.
Summary of the invention
The purpose of this utility model is to provide a kind of submersible sewage pump pump case moulding mould of good forming effect, even, the coarse technical problem of size of pump house wall thickness ununiformity of producing to solve the pump case forming method of prior art.
The mould using in submersible sewage pump pump case forming method of the present utility model adopts following technical scheme: a kind of submersible sewage pump pump case moulding mould, comprise punch and die, the outer surface of punch coincide and coordinates with submersible sewage pump pump case inner surface, die inside has the inner chamber of depression, and the inner surface of die inner chamber coincide and coordinates with submersible sewage pump pump case outer surface.
The top of described die is provided with and the bolted cope match-plate pattern of die, and the below of described punch is provided with and the bolted lower bolster of punch.
The periphery of described punch bottom is arranged with blank holder, and blank holder is positioned at described lower bolster top position, and described lower bolster is provided with push rod perforation, is provided with for the push rod of jack-up blank holder upwards in push rod perforation.
On position near the inner chamber caving in the following table of described die, there is protruding boss, on the position of the upper surface of described blank holder corresponding to die boss, have and the identical groove coordinating of described boss.
The beneficial effects of the utility model are: after the semi-finished articles of submersible sewage pump pump case completes, utilize mould of the present utility model to suppress semi-finished articles, semi-finished articles is placed on punch, put and just fit to past position of transferring again, again die is placed on semi-finished articles, respectively punch and die are exerted pressure, by part on punch extruded serni-finished product part, on semi-finished articles, part is expanded into type outside depressing in punch, by part under die extruded serni-finished product part, under semi-finished articles, part is in the outer type of being shrunk to of depressing of die. The utility model utilizes mould can make semi-finished articles carry out upper swollen lower contracting, utilizes mould of the present utility model can make pump case product wall thickness even. Follow the upper and lower process of metal flow hydraulic pressure by upper contracing under swollen, make the wall thickness of shaped article basically identical, be controlled at ± 0.2mm of the error of wall thickness. The utility model is the forming process of a swollen contracting, and amount of compression is relatively little, and mould is also difficult for pulling, and has obtained good manufacturability and economy.
Further, utilize cope match-plate pattern and the lower bolster can be respectively to die and the punch application of force, prevent directly to die and punch application of force damage die surface.
Further, utilize blank holder and push rod to be convenient to utilize mould to carry out moulding to semi-finished articles.
Further, the boss of patrix and the groove of blank holder coincide to be combined with and are beneficial to mould and locate accurately, make formed product effective.
Brief description of the drawings
Fig. 1 is the structural representation of the embodiment of the utility model submersible sewage pump pump case moulding mould;
Fig. 2 is the schematic diagram that in Fig. 1, mould carries out blanking to semi-finished articles.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The structure of a kind of embodiment of the utility model submersible sewage pump pump case moulding mould as shown in Figure 1 to Figure 2, it comprises punch 1 and die 2, the outer surface of punch 1 coincide and coordinates with submersible sewage pump pump case inner surface, die 2 inside have the inner chamber of depression, and the inner surface of die 2 inner chambers coincide and coordinates with submersible sewage pump pump case outer surface. The top of described die 2 is provided with the cope match-plate pattern 5 being connected by bolt 7 and pin 6 with die 2, the below of described punch 1 is provided with the lower bolster 4 being connected by bolt 7 and pin 6 with punch 1, utilize cope match-plate pattern 5 and the lower bolster 4 can be respectively to die and the punch application of force, prevent directly to die and punch application of force damage die surface. The periphery of described punch 1 bottom is arranged with blank holder 3, and blank holder 3 is positioned at described lower bolster 4 top positions, and described lower bolster 4 is provided with push rod perforation, is provided with for the push rod 8 of jack-up blank holder 3 upwards in push rod perforation. On position near the inner chamber caving in the following table of described die 2, there is protruding boss 9, on the position of the upper surface of described blank holder 3 corresponding to die boss 9, have and the identical groove 10 coordinating of described boss, the boss 9 of patrix and the groove of blank holder 10 coincide to be combined with and is beneficial to upper die and lower die and locates accurately, makes formed product effective.
The utility model mould in use, first that punch 1 is fixing with lower bolster 4, again blank holder 3 is enclosed within on punch 1, utilize push rod 8 blank holder 3 to be pushed up to the position of punch 1 half, again the semi-finished articles of conical shell structure is set on punch 1, semi-finished articles is put and is just fitted to past position of transferring again, and some is concentric with mould to ensure inner side, then die 2 is set in outside semi-finished articles, cope match-plate pattern 5, die 2 move downward together, move to die bottom, semi-finished articles and blank holder top and fit completely, obtain pump case profiled member. The utility model is by part on punch 1 extruded serni-finished product part, and on semi-finished articles, part is expanded into type outside depressing in punch 1, and by part under die 2 extruded serni-finished product parts, under semi-finished articles, part is in the outer type of being shrunk to of depressing of die 2.
