The utility model relates to the field of stamping dies, in particular to a stripping structure for the movable tapered wedge of a non-vertical upward hole-flanging and edge-flanging female die. The stripping structure is suitable for the automobile industry and hardware pieces and comprises a driving part and a movable female die working part, wherein the driving part is the upper die of stamping equipment, a driving block is arranged on the upper die, the front end of a driving surface is tapered, the rear side of the driving surface is a vertical contact surface, the length of the vertical contact surface is required to be larger than the vertical travel of the upper hole-flanging and edge-flanging tapered wedge assembly of a lower die and certain allowance is kept; and the movable female die working part is installed on an upper die pressure plate and comprises a limiting assembly, a guide assembly and a spring return assembly. The utility model has the advantages that the situation that the precision of the finished pieces is affected because the material is blocked and brought away by the female die after non-vertical upward hole flanging and edge flanging is avoided, especially under the situations of high precision, less processes, small space and the like, the required precision of the finished pieces can be ensured, the number of the processes is not increased and the cost is saved.
Description
Technical field
The utility model relates to the diel field, especially is applicable to a kind of non-perpendicular flanging upward hole, the movable wedge material returned of the flange die structure of auto industry and five metals product.
Background technology
Along with the development of automobile industry and the maturation day by day of Sheet Metal Forming Technology, the shape of product becomes increasingly complex, required precision improves constantly, simultaneously, in view of the increase of cost pressure, just need the usage quantity of stamping procedure, mould size and lathe constantly to reduce, save cost, this just causes, and the design space many times to occur little, the demanding situation of part accuracy.
Summary of the invention
The utility model non-perpendicular flanging upward hole occurs at operation after a little while, and flange impacts the situation of part accuracy, and to non-perpendicular flanging upward hole, behind the flange, what mould die sinking recurve was molded as gets stuck, and the band material has influenced the situation of part accuracy and revised.
The technical solution of the utility model is:
A kind of non-perpendicular flanging upward hole, the movable wedge material returned of flange die structure, this structure comprises: drive part and movable matrix working portion; Wherein drive part is the patrix of pressing equipment, and patrix is provided with drive block, and the drive surface front end is a rake angle, and rear side is vertical contact-making surface, and the length of vertical contact-making surface needs the vertical stroke greater than hole flanging, flange wedge assembly on the counterdie, and certain surplus is arranged; Wherein the movable matrix working portion is installed on the patrix holding pad, and the movable matrix working portion comprises limit assembly, guidance set and spring return assembly.
Above-mentioned limit assembly is a caging bolt.
Above-mentioned guidance set is a guide pin bushing.
Above-mentioned spring return assembly is a retracting spring.
Further, be provided with wearing plate at the movable matrix working portion.
The beneficial effects of the utility model are: solved non-perpendicular flanging upward hole, die gets stuck behind the flange, and the band material has influenced the situation of part accuracy, especially under precision height, situation such as operation is few, the space is little, both can guarantee the required precision of product, not increase operation again, save cost.
Description of drawings
Fig. 1 is that the utility model is installed in the sectional structure schematic diagram on the holding pad
1. insert hole flanging on 4. patrix drive blocks, 5. movable matrixes, 6. caging bolts, 7. retracting springs, 8. guide pin bushings, 9. wearing plates, 10. counterdies, 11. punch inserts, 12. counterdies, flange wedge assembly of patrix 2. patrix holding pads 3. holding pads.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
The utility model discloses a kind of non-perpendicular flanging upward hole, the movable wedge material returned of flange die structure.Its structure comprises: drive part and movable matrix working portion.Wherein drive part is the patrix 1 of pressing equipment, patrix 1 is provided with drive block 4, the drive surface front end is a rake angle, rear side is vertical contact-making surface, rake angle is for making movable matrix arrive the operating position, and the length of vertical contact-making surface needs the vertical stroke greater than hole flanging, flange wedge assembly 12 on the counterdie, and certain surplus is arranged, the hole flanging assembly just can hole flanging on the counterdie of back because movable matrix need put in place earlier, and the length of therefore vertical contact-making surface needs the vertical stroke greater than last hole flanging; Owing to consider processing problems, wherein the movable matrix working portion is installed in patrix holding pad 2 holding pads and inserts on 3, and the movable matrix working portion comprises limit assembly, guidance set and spring return assembly.Limit assembly is the stroke of the movable hole flanging of restriction die, flange; guidance set is to make movable matrix in continuous active operation; still can keep the precision of movable matrix 5 when work, the spring return assembly is to make movable matrix at hole flanging, and the product of backhaul and die are not interfered behind the flange.Described limit assembly is a caging bolt 6, and guidance set is a guide pin bushing 8, and the spring return assembly is a retracting spring 7.The movable strokes of caging bolt 6 restriction dies, the guiding of guide pin bushing 8 is guaranteed the hole flanging precision of movable matrix 5, retracting spring 7 makes after the work movable matrix 5 backhauls.
In addition, also can be provided with wearing plate 9.Wearing plate 9 main effects are anti-side forces, guarantee that movable matrix 5 still keeps required precision in working long hours.
Below the course of work of the present utility model is described:
The utility model is after patrix holding pad 2 is pressed onto product, patrix drive block 4 begins to contact movable matrix 5, because patrix drive block 4 front ends are the inclined-plane, also can promote movable matrix 5 with the contact-making surface of movable matrix 5 for the inclined-plane, movable matrix 5 moves down along guide pin bushing, retracting spring 7 compressions, after treating that movable matrix 5 arrives the assigned work position, patrix drive block 4 continues downwards, what contacted movable matrix 5 inclined-planes this moment is the vertically-guided face, can not influence the position of movable matrix 5, the length of vertical contact-making surface needs greater than hole flanging on the counterdie, the vertical stroke of flange wedge group 12, and certain surplus is arranged.Hole flanging on the counterdie, flange wedge group 12 and punch insert 11 are installed on the counterdie 10, and hole flanging on punch insert 11 and the counterdie, the punch of flange wedge group 12 need be provided with the guiding relation, guarantee precision and life-span, hole flanging on the counterdie then, flange wedge group 12 is started working, behind the hole flanging, hole flanging on the counterdie, the 12 first backhauls of flange wedge group, treat hole flanging on the counterdie, after 12 backhauls of flange wedge group, the intact vertical contact-making surface head inclined-plane of patrix drive block 4 rollbacks begins to contact movable matrix 5, movable matrix 5 is subjected to the effect of spring 7 compression stresses, the inclined-plane of contact patrix drive block 4 begins backhaul, when patrix drive block 4 inclined-planes broke away from movable matrix 5, movable matrix 5 backhauls finished, and move on the holding pad 2 then, product can be with material, get stuck, finished a work period.
