Description
Technical field
The utility model relates to the mesh plate processing technique field, is specifically related to a kind of thin material metal micro-perforating die.
Background technology
Often can use the metal mesh opening thin plate on the parts of the digital product such as notebook computer, digital camera; the metal mesh opening gauge of sheet of these parts is in submillimeter or micron dimension; be provided with microwell array on the metal mesh opening thin plate, usually all require very high to size and the precision of micropore.
Existing punching processing mould adopts the mould of a punching out machine-shaping usually, the minimum-value aperture of the micropore that this mould is gone out in the prior art is usually thick greater than 1.5 material, the pitch of holes of microwell array is also larger, when adopting this microwell array that Mould Machining aperture is little, mesh is intensive, sheet material is out of shape easily, punching burr is sharp, and flatness is difficult to guarantee.Therefore, existing punching processing mould is difficult processes the microwell array that the aperture is little, mesh is intensive.For example when need to thickness be the aluminium sheet processing aperture of 0.8mm thick less than 1 material, when pitch of holes is expected thick microwell array less than 2.5, difficulty with existing diel processing is very big, usually can only adopt the method for etching and processing, yet the production cost of processing method is high, the process-cycle is long, is unfavorable for volume production.
The die punching processing method has the advantage that life cycle of the product is short, production cost is low, needs a kind of thin material metal micro-perforating die that can punching out processes the microwell array that the aperture is little, pitch of holes is little in the prior art badly.
Summary of the invention
The deficiency that the utility model exists in order to overcome prior art provides a kind of thin material metal micro-perforating die that can punching out processes the microwell array that the aperture is little, pitch of holes is little.
The utility model is achieved through the following technical solutions: a kind of thin material metal micro-perforating die, it comprises counterdie and can press down patrix with transverse shifting, patrix comprises upper bolster, train wheel bridge, baffle plate and the stripper plate that sets gradually from top to bottom, be connected with the drift matrix at train wheel bridge, the drift of drift matrix passes baffle plate and stripper plate stretches out downwards; Counterdie comprises lower bolster, lower bolster, die shoe, bottom seat pad and the bottom plate that sets gradually from top to bottom, be provided with being used for of protruding upward at lower bolster and locate at least two interior alignment pins of thin metal material workpiece and at least eight outside fix pins that are used for location patrix and counterdie relative position, on patrix, be provided with locating hole corresponding to interior alignment pin and outside fix pin.
Be provided with three the interior alignment pins that are used for locating thin metal material workpiece that protrude upward at lower bolster.
Be provided with for ten outside fix pins of locating patrix and counterdie relative position at lower bolster.
The course of work of the utility model thin material metal micro-perforating die comprises the steps:
1) as shown in Figure 2, at first utilize punching to make two interior locating holes in the metallic sheet stock upper punch, these two interior locating holes mutually across a certain distance, to guarantee accurate positioning;
2) as shown in Figure 3, metallic sheet stock is positioned on the counterdie of thin material metal micro-perforating die, is positioned at two locating holes that two alignment pins on the counterdie stretch into metallic sheet stock, then carry out the workpiece location, patrix presses down, and punching out goes out the first microwell array;
3) as shown in Figure 4, with step 2) same method go out the second microwell array in the interporal lacuna place punching out of the first microwell array of metallic sheet stock;
4) with step 2) same method go out the 3rd microwell array in the first microwell array of metallic sheet stock, the interporal lacuna place punching out of the second microwell array, the first microwell array, the second microwell array and the 3rd microwell array consist of the microwell array that the aperture is little, mesh is intensive.
Step 2), 3), 4) all in same mould, carry out, go out the first microwell array, the second microwell array and the 3rd microwell array by mobile patrix in the diverse location punching out of metallic sheet stock.
The beneficial effects of the utility model are: the utility model is by repeatedly punching out microwell array processing, the density of enhancing microwell array, the stress point spacing of each punching out microwell array processing is all larger, so that the material of metallic sheet stock walks and all controls within the specific limits in each punching out process, make metallic sheet stock not yielding, be difficult for producing punching burr, flatness is better.The utility model can punching out process the microwell array sheet metal that the aperture is little, mesh is intensive, and it has, and production technology is simple, precision is high, with short production cycle, advantage that production cost is low.The utility model can punching out go out the second best in quality metal mesh opening thin plate, is fit to the batch machining of metal mesh opening thin plate.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in detail.
As shown in Figure 1, a kind of thin material metal micro-perforating die, it comprises counterdie and can press down patrix with transverse shifting, patrix comprises upper bolster 1, train wheel bridge 2, baffle plate 3 and the stripper plate 4 that sets gradually from top to bottom, be connected with the drift matrix at train wheel bridge 2, the drift of drift matrix passes baffle plate 3 and stripper plate 4 stretches out downwards; Counterdie comprises lower bolster 5, lower bolster 6, die shoe 7, bottom seat pad 8 and the bottom plate 9 that sets gradually from top to bottom, be provided with being used for of protruding upward at lower bolster and locate two interior alignment pins of thin metal material workpiece and ten outside fix pins that are used for location patrix and counterdie relative position, on patrix, be provided with locating hole corresponding to interior alignment pin and outside fix pin.
In the utility model, behind the punching out locating hole, again metallic sheet stock has been carried out three punching out microwell array processing, certainly, according to the actual conditions needs, also can process the punching out microwell array that metallic sheet stock is carried out more than three times.Wherein, step 2), 3), 4) can in same thin material metal micro-perforating die, carry out, go out the first microwell array, the second microwell array and the 3rd microwell array by mobile patrix in the diverse location punching out of metallic sheet stock.Thin material metal micro-perforating die of the present utility model can be that to process the aperture be that 0.5-0.7 material is thick, pitch of holes is 1.2-1.5 the microwell array that material is thick for the aluminium sheet of 0.8mm at thickness.
Should be noted that at last; above content is only in order to illustrate the technical solution of the utility model; but not to the restriction of the utility model protection domain; the simple modification that those of ordinary skill in the art carries out the technical solution of the utility model or be equal to replacement does not all break away from essence and the scope of technical solutions of the utility model.
