Abstract
The utility model relates to a die for a cross shearing machine, which comprises an upper die (1) and a lower die (2), and is characterized in that the upper die (1) comprises an upper die carrier (1.1) and the lower die (2) comprises a lower die carrier (2.1) at the bottom; a tool holder (2.2) is arranged on the lower die carrier (2.1); a discharge plate (2.3) and a blade (2.4) which are superposed are arranged on the tool holder (2.2); a puncher pin fixing base (2.5) is arranged above the discharge plate (2.3); four springs (2.6) are connected between the four corners of the lower surface of the puncher pin fixing base (2.5) and the upper surface of the discharge plate (2.3); a pressing board (2.8) is fixed at the top of the puncher pin fixing base (2.5). The die for the cross shearing machine has the advantages of longer service life of the puncher pin and higher accuracy of the sheared product.
Description
Technical field
The utility model relates to a kind of cross cut shears mould, belongs to the plant equipment field.
Background technology
Cross cut shears is the processing and fabricating with silicon steel sheet for transformer core, the drift of tradition cross cut shears mould is arranged on patrix, because the vertical precision of assembling reason drift need to be proofreaied and correct repeatedly, and be difficult to ensure card vertical precision very, if the vertical precision of drift is bad, not only in the punching process, the service life of drift is lower, and the Product Precision that punching goes out is poor, once again change the rectify perpendicular that drift re-starts drift again.Therefore it is lower that traditional cross cut shears mould has service life of drift, the shortcoming that the Product Precision that punching goes out is poor.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of service life of drift higher, the cross cut shears mould that the Product Precision that punching goes out is higher.
The purpose of this utility model is achieved in that
A kind of cross cut shears mould, comprise patrix and counterdie, described patrix comprises a top mold frame, the bottom surface level of described top mold frame, described counterdie comprises the lower mold holder of bottom, be provided with tool rest on described lower mold holder, described stripper and the blade of arranging up and down that be provided with, described stripper top is provided with the drift holder, be connected with four springs between four jiaos of the lower surfaces of described drift holder and stripper upper surface, offer the drift installing hole on described drift holder, be provided with drift in described drift installing hole, the stripper corresponding position of described drift installing hole below is provided with the bore of the punch of up/down perforation, the lower end of described drift extends in bore of the punch, the top of described drift holder is fixed with pressing plate, the end face level of described pressing plate.
Compared with prior art, the beneficial effects of the utility model are:
The utility model drift holder is arranged on counterdie, make the vertical precision of drift higher, during punching, top mold frame is carried out the plane beating to pressing plate, makes stressed uniform and stable more, thereby the service life that this cross cut shears mould has drift is higher, the advantage that the Product Precision that punching goes out is higher.
The accompanying drawing explanation
Fig. 1 is the utility model cross cut shears mould structure schematic diagram.
Wherein:
Patrix 1, top mold frame 1.1, lead hole 1.2
Counterdie 2, lower mold holder 2.1, tool rest 2.2, stripper 2.3, blade 2.4, drift holder 2.5, spring 2.6, drift 2.7, pressing plate 2.8.
The specific embodiment
Referring to Fig. 1, a kind of cross cut shears mould that the utility model relates to, comprise patrix 1 and counterdie 2, described patrix 1 comprises a top mold frame 1.1, the bottom surface level of described top mold frame 1.1, offer vertical lead hole 1.2 on described top mold frame 1.1, described counterdie 2 comprises the lower mold holder 2.1 of bottom, be provided with tool rest 2.2 on described lower mold holder 2.1, described 2.2 are provided with stripper 2.3 and the blade 2.4 of arranging up and down, described blade 2.4 is alloy blade, spacing between described stripper 2.3 and blade 2.4 is 3mm, described stripper 2.3 tops are provided with drift holder 2.5, be connected with four springs 2.6 between four jiaos of the lower surfaces of described drift holder 2.5 and stripper 2.3 upper surfaces, offer the drift installing hole of one or more up big and down small stepped ramp type on described drift holder 2.5, be provided with the drift 2.7 of up big and down small stepped ramp type in described drift installing hole, stripper 2.3 corresponding positions of described drift installing hole below are provided with the bore of the punch of up/down perforation, the lower end of described drift 2.7 extends in bore of the punch, the lower end of described drift 2.7 is 3 ~ 5mm apart from the lower surface of stripper 2.3, the top of described drift holder 2.5 is fixed with pressing plate 2.8 by connecting bolt, the end face level of described pressing plate 2.8.
Operation principle:
During work, by 1.1 pairs of pressing plates 2.10 of top mold frame, patted, the silicon steel sheet of controlling between 2.8 pairs of strippers 2.3 of drift and blade 2.4 carries out punching, due to the setting of four springs 2.6, drift holder 2.5 is arranged on counterdie 2, makes the vertical precision of drift higher, during punching, 1.1 pairs of pressing plates of top mold frame 2.8 carry out the plane beating, make stressed uniform and stable more, thereby the service life of drift is higher, the Product Precision that punching goes out is higher.
