The utility model adds and workpiece is placed on locating piece fixing man-hour, along with punch press promotion cope match-plate pattern is descending, make the translation of left and right wedge centering, the conversion of realizable force and displacement, close on the bottom dead centre of punch press, elastic positioning pin release pressure, workpiece pressing, when punching machine stroke arrives operating position, left and right wedge symmetry is exerted pressure, and completes the extruding of workpiece Local Symmetric, and then workpiece is taken off in backhaul, continuous operation, the workpiece of processing by the utility model has the advantages that product size is stable, simple to operate, production efficiency is high, cost is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of novel mould structure of realizing symmetrical local extruding, it comprises cope match-plate pattern 1 and lower bolster 2, on lower bolster 2, be provided with locating piece 3, in locating piece 3 bilateral symmetry, be provided with left guide pad 4 and right guide pad 5, on left guide pad 4 and right guide pad 5, be respectively equipped with left slider 6 and right slide block 7, the inner side of left slider 6 and right slide block 7 is respectively equipped with left drift 8 and right drift 9, between left slider 6 and right slide block 7 and cope match-plate pattern 1, be respectively equipped with left wedge 10 and right wedge 11, left wedge 10 and right wedge 11 are fixed on cope match-plate pattern 1 bottom, the hypotenuse of left wedge 10 and right wedge 11 coordinates with left slider 6 and right slide block 7 respectively, on the position of the corresponding locating piece 3 in cope match-plate pattern 1 bottom, be provided with elastic positioning pin 12.
Operation principle of the present utility model is as follows:
1, open punch press, adjust punching machine stroke, meet production shut height, complete production preparation.
2, processed workpiece 13 is put on die spacer block 3, along with upper die of punching press plate 1 is descending, left and right wedge 10,11 centering translations, the conversion of realizable force and displacement, close on the bottom dead centre of punch press, elastic positioning pin 12 release pressures, workpiece pressing, when punching machine stroke arrives operating position, left and right wedge 10,11 symmetries are exerted pressure, and complete workpiece 13 Local Symmetric extruding, backhaul, take off workpiece, continuous operation.
The utility model adopts elastic positioning pin, can synchronize compression, the extruding work of workpiece of realizing in time with both sides wedge, realizes the extrusion process used for forming of arc surface complanation, improves stablizing of extrusion process used for forming, thereby reaches the quality requirements of workpiece; High accuracy wedge, its power transmission and displacement are accurate, effectively control deformation extent and the deflection of crimp part, guarantee extrusion deformation degree and the symmetry at workpiece deformation position; Solve quality problem, efficiency, the Cost Problems of two planes of symmetry of split crankshaft bearing gear face of cylinder processing.
