--blanking--drilling---surface treatment that the moulding process of metal coating cover plate is mainly: get the raw materials ready.Cash belongs to that there is following problem in the processing in hole on the cover sheet:
(1) hole count series is many: according to design requirement, all can be uniformly distributed with 3,4,6,8,12 holes on the cover sheet of different size.
(2) Multi-Aperture Size: Different cover holes uniform hole diameter
(3) the material thickness specification is many: according to designing requirement, the cover sheet of different size can have 1mm, 1.5mm, 2mm, four kinds of material thicknesses of 3mm.
(4) uncertain factor is many: the quantity in hole, diameter, distribution circle are different because of the difference of product design.
(5) number of molds is many: under the situation of not considering the aperture, if every kind of specification, a kind of hole count and diameter are 1 mold drilling, all getting all the drilling mould ready just needs 180 (36 * 5=180) molds.The product manufacturing expense is high, mould takes up room many.
Therefore, need a kind of general punching die that can process the metal coating cover plate of plurality of specifications, different hole counts of development.
Summary of the invention
The purpose of the utility model is to provide a kind of general perforating die of metal coating cover plate that can process the metal coating cover plate of plurality of specifications, different hole counts.
The technical scheme of the utility model is following:
The general perforating die of a kind of metal coating cover plate, it comprises lower bolster, and lower bolster is provided with die, also is provided with on the said lower bolster and decides flitch, decides to be fixed with on the flitch stripper, and an end of described stripper is processed with manhole; The general perforating die of described metal coating cover plate also comprises the cope match-plate pattern that is located at lower bolster top, and this cope match-plate pattern center is provided with convex mould base, below cope match-plate pattern, outside this convex mould base, is provided with punch retainer, and said convex mould base lower end is fixed with columned punch; Described punch is coaxial with die; Described lower bolster is provided with groove, is provided with positioning sleeve in the groove, is provided with alignment pin in the positioning sleeve, alignment pin lower end cover loading nut.
In the general perforating die of above-mentioned metal coating cover plate, also be fixed with guide pillar on the described lower bolster, the lower surface of said cope match-plate pattern is provided with rotating guide pin bushing, and described guide pin bushing and guide pillar are threaded.
In the general perforating die of above-mentioned metal coating cover plate, described cope match-plate pattern is provided with mounting groove, is processed with through hole in the groove, convex mould base is passed this through hole install, and is fixed with the die shank of annular in the groove.
In the general perforating die of above-mentioned metal coating cover plate, a side of described lower bolster is provided with lifting bolt.
The beneficial effect of the utility model is: through designing double-deck processing template; And utilize being threaded of guide pin bushing and guide pillar; Accurately locate the cope match-plate pattern height; And the adjustable location structure that combines positioning sleeve, alignment pin to form, make different size and the identical position, hole of hole count all distributes point-blank, so just can utilize positioning sleeve on this straight line, to move the location of accomplishing position, different hole.Protruding, die adopts dismountable installation and design, can select dismounting according to the needs of punching size, has saved the cost of entire die transposing, has saved a large amount of moulds, and has reduced the time of clamping frock.

Among the figure: 1. cope match-plate pattern; 2. punch retainer; 3. screw; 4. die shank; 5. pin; 6. screw; 7. convex mould base; 8. holding screw; 9. punch; 10. lower bolster; 11. nut; 12. positioning sleeve; 13. alignment pin; 14. die; 15. screw; 16. decide flitch; 17. lifting bolt; 18. stripper; 19. bolt; 20. guide pin bushing; 21. guide pillar; 22. lathe table top.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further explain.
As shown in Figure 1, be processed with mounting groove at cope match-plate pattern 1, be processed with through hole in the groove, convex mould base 7 is passed this through hole install, and the die shank 4 of annular is installed in the groove, through screw 3 die shank 4 is fixed in the mounting groove of cope match-plate pattern 1 again.
Outside the lower surface of cope match-plate pattern 1, convex mould base 7 through pin 5 and screw 6 fixed installation punch retainers 2, further to convex mould base 7 location.Punch 9 is installed through holding screw 8 in these convex mould base 7 lower ends.Described punch 9 is cylindric, and the big I of punch 9 is made according to the needs of punching size on the metal coating cover plate.The lower surface of described cope match-plate pattern 1 fixedly mounts columnar guide pin bushing 20.
As depicted in figs. 1 and 2, at lower bolster 10 upper surface installation and processing grooves, place die 14 in the groove; And on lower bolster 10, decide flitch 16 through screw 15; And through bolt 19 stripper 18 is installed in and decides on the flitch 16, being processed with manhole at an end of described stripper 18, above-mentioned punch 9 just in time passes this manhole; And over against described die 14, promptly punch 9 is coaxial with die 14.Also fixedly mount two guide pillars 21 on the described lower bolster 10, the size of this guide pillar 21 and above-mentioned guide pin bushing 20 are suitable, and during work, guide pillar 21 rotates down the spacing of guide pin bushing 20.Can cope match-plate pattern 1 and lathe be connected,, regulate the height of cope match-plate pattern 1 through the rise and fall of lathe, and spacing through the cooperation of guide pillar 21 and guide pin bushing 20.
Three grooves of processing on lower bolster 10, installing and locating cover 12 flows out assemblage gap in each groove; Positioning sleeve 12 can be rotated in groove; At positioning sleeve 12 inner installing and locating pins 13, and alignment pin 13 stretched out the part cover loading nut 11 of lower bolster 10, make its move up and down obtain spacing.
For the ease of whole device is installed on the lathe, two lifting bolts 17 are installed in a side of described lower bolster 10.
With the example that is processed as of 4 mesoporous metal cover sheets, its process is following:
1) whole device is put into lathe table top 22, the adjustment lathe is fixed on die shank 4 in the slide block; Mould is adjusted to the lathe top dead-centre; The size of the model of metal coating cover plate of processing, and punching is as required confirmed the size of corresponding punch 9, die 14; On lower bolster 10, choose suitable angle hole, the nut 11 on fastening positioning sleeve 12 and the alignment pin 13; The screw of deciding on the flitch 16 15 is fastening, so that confirm the back gauge of product.And will regulate the position of guide pin bushing 20 on guide pillar 21, and make whole device highly reduce, up to punch 9 and die 14 matched moulds, this moment is lower bolster 10 fixedly.After adjusting die-cut height according to the material thickness of product, fastening entire die and lathe.
2) position of adjustment guide pin bushing 20 on guide pillar 21 makes whole device highly rise, and puts into the embryo spare that will process, and installation steps 1 then) said, choose suitable position, up to punch 9 and die 14 matched moulds, punching out goes out first hole.
3) alignment pin 13 is placed in first hole that processes, repeated the matched moulds step, process second hole;
4) the entire die position is motionless, and alignment pin 13 is placed in second hole that processes, and carries out the processing in the 3rd hole;
5) the entire die position is motionless, and alignment pin 13 is placed in the 3rd hole that processes, and accomplishes the processing in the 4th hole.
Through above five steps, accomplish the processing of 4 mesoporous metal cover sheets.
The hole count that same principle adopts the general perforating die of metal coating cover plate of the present invention can process the different size specification is 3,4,6 metal coating cover plate.
