Abstract
The invention discloses a stretchable-piece pre-punching mold which comprises an upper mold plate and a puncher pin installed below the upper mold plate. A lower mold plate and a concave mold plate arranged above the lower mold plate are arranged below the puncher pin, and a plurality of vertically-upward locating inserts are arranged on the concave mold plate. According to the stretchable-piece pre-punching mold, after the specific size of a punching hole in a stretchable piece on a plane workpiece is calculated, punching is firstly carried out through the stretchable-piece pre-punching mold; the vertically-upward locating inserts are arranged on the concave mold plate of the stretchable-piece pre-punching mold for plane punching, the workpiece is located through the locating inserts, the workpiece can be conveniently processed in the follow-up stretching process after punching is completed, the locating inserts are conveniently disassembled, assembled and maintained, the maintenance cost of the stretchable-piece pre-punching mold is easily reduced, and the stretchable-piece pre-punching mold is used for the field of punching molds.
Description
Technical field
The present invention relates to a kind of mould structure, particularly relate to a kind of tensioning member pre-punched hole mould.
Background technology
To some tensioning members highly not high and that sidewall also needs to carry out special-shaped punching that stretches, existing old technology stamping-out carries out sidewall punching after being generally stretching again, the shortcoming that one-shot mould upper punch is cut out is no matter whether the hole of tensioning member side is special-shaped, all orientation problem to be considered, repeatedly stamping-out must be carried out.The punching of progressive die sidewall needs repeatedly stamping-out equally, thereby has increased mould work step, has strengthened mold integral length.
Tensioning member carries out stamping-out after having stretched simultaneously, need to consider the arcuate structure after tensioning member stretches, and on Design of Dies, the cutting edge of blanking die conventionally can be thinner, easily cause cutting edge to damage, and die change operating process is loaded down with trivial details, and maintenance cost is huge.
Thus, new production technology can be after calculating stamping-out hole on the tensioning member size on flat work pieces, first carry out stamping-out, stretch again, new technology can be simplified the manufacture craft of tensioning member, but be badly in need of a kind of new blanking die, solve tensioning member plane stamping-out and the orientation problem of two inter processes that stretch.
Summary of the invention
The invention provides a kind of tensioning member pre-punched hole mould that can accurately position tensioning member.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of tensioning member pre-punched hole mould, comprise cope match-plate pattern and the drift that is installed on cope match-plate pattern below, drift below is provided with lower bolster and is arranged at the concave template of lower bolster top, concave template is provided with some location mold inserts straight up, in concave template, be provided with some mold insert putting grooves, each is located mold insert and is positioned over respectively in each mold insert putting groove, and each is located mold insert and comprises the center positioning hole mold insert that is arranged at concave template center.
In above-mentioned tensioning member pre-punched hole mould, cope match-plate pattern bottom is provided with the loading and unloading material plate around drift.
In above-mentioned tensioning member pre-punched hole mould, lower bolster is provided with the die backing plate that is positioned at concave template below, and the bottom of lower bolster is provided with counterdie backing plate.
In above-mentioned tensioning member pre-punched hole mould, on concave template, be also provided with the flower shelves mold insert around center positioning hole mold insert scatter distributions.
In above-mentioned tensioning member pre-punched hole mould, on concave template, be also provided with and be positioned at top punching mold insert and the correcting hole mold insert that four right angles of workpiece are.
Beneficial effect of the present invention: this tensioning member pre-punched hole mould is after calculating stamping-out hole on the tensioning member concrete size on flat work pieces, by this pre-punched hole mould, first carry out stamping-out, carry out being provided with some location mold inserts straight up on the concave template of pre-punched hole mould of plane stamping-out, by location mold insert, carry out the location of workpiece, after completing, stamping-out facilitate workpiece to process in follow-up stretching process, and respectively locate mold insert easy disassembly and maintenance, be conducive to reduce the maintenance cost of mould.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described:
Fig. 1 is embodiment of the present invention overall structure schematic diagram;
Fig. 2 respectively locates the mold insert schematic diagram of arranging in embodiment of the present invention concave template.
The specific embodiment
With reference to Fig. 1, Fig. 2, the present invention is a kind of tensioning member pre-punched hole mould, comprise cope match-plate pattern 1 and the drift 2 that is installed on cope match-plate pattern 1 below, drift 2 belows are provided with lower bolster 3 and are arranged at the concave template 4 of lower bolster 3 tops, and concave template 4 is provided with some location mold inserts straight up.
This tensioning member pre-punched hole mould is after calculating stamping-out hole on the tensioning member concrete size on flat work pieces, by this pre-punched hole mould, first carry out stamping-out, carry out being provided with some location mold inserts straight up on the concave template 4 of pre-punched hole mould of plane stamping-out, by location mold insert, carry out the location of workpiece, after completing, stamping-out facilitate workpiece to process in follow-up stretching process, and respectively locate mold insert easy disassembly and maintenance, be conducive to reduce the maintenance cost of mould.
In the present embodiment, cope match-plate pattern 1 bottom is provided with the loading and unloading material plate 5 around drift 2.
In the present embodiment, lower bolster 3 is provided with the die backing plate 6 that is positioned at concave template 4 belows, and the bottom of lower bolster 3 is provided with counterdie backing plate 7.
In the present embodiment, be provided with some mold insert putting grooves in concave template 4, each is located mold insert and is positioned over respectively in each mold insert putting groove, and each is located mold insert and comprises the center positioning hole mold insert 41 that is arranged at concave template 4 centers.
In the present embodiment, on concave template 4, be also provided with the flower shelves mold insert 42 around center positioning hole mold insert 41 scatter distributions.
In the present embodiment, on concave template 4, be also provided with and be positioned at top punching mold insert 43 and the correcting hole mold insert 44 that four right angles of workpiece are.
From die life, flat work pieces is carried out to flat shock wave, and mould structure is more stable, and easy-maintaining more, six flower shelves mold inserts 42 on concave template 4, have been filled, and flower shelves cutting edge strength is large, can not only have several cutting edge limit at zero point as old technology, what adopt due to us is mold insert simultaneously, if mold insert damages, we can directly change mold insert, and it is suitable easy repairing, also very little to the Influence of production in workshop.
Certainly, the invention is not limited to above-mentioned embodiment, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to spirit of the present invention, and the modification that these are equal to or replacement are all included in the application's claim limited range.
