Abstract
The utility model discloses a novel rolling die for a hinge, which relates to a stamping die and comprises an upper die base, a lower die base, an upper die and a lower die, wherein a fixing groove is formed on the lower die; the upper die is connected with the lower surface of the upper die base by a compressing rubber gasket; a forming slide block is arranged on the lower die base and connected with the lower die by a return spring and can slide relative to the lower die base; corresponding arc grooves are formed at the lower end of the upper die and the upper end of the forming slide block; an oblique plane is arranged on the side of the forming slide block, far away from the upper die; and a tapered wedge matched with the oblique plane is arranged on the lower surface of the upper die base. The novel rolling die has large forming force on a rolling piece and is good in rolling quality, the rolling piece does not deform easily, and the rejection rate is low.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of new hinges volume circle mould.
Background technology
Crooked part is one of punching parts that quantity was maximum during Modern Industry Products, automobile, electrical equipment, instrument and instrument were made.Its principal mode has: V-arrangement, U-shaped, Z-shaped, crimp and other complex-shaped parts, the crooked part major part is to adopt bending die to carry out bending forming.The volume circle is a kind of bending forming method of sheet metal bending one-tenth near closed cylinder, hinge shape part is exactly to adopt the method for volume circle to make, the processing of hinge shape part generally is to adopt volume circle mould, existing volume circle mode structure is fairly simple, comprises upper die and lower die, has deep-slotted chip breaker on the patrix, be provided with compact heap on the counterdie, during shaping workpiece is placed between counterdie and the compact heap, patrix is descending, and workpiece deep-slotted chip breaker along patrix under pressured state rolls to shape.The existing volume circle contour forming only deep-slotted chip breaker of top mould is finished, and plastic force is little, rolls up the of poor quality of circle, the easy distorted of volume circle part, and percent defective is high.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of new hinges volume circle mould, and large to the plastic force of rolling up round part, volume circle quality is good, and volume circle part is difficult for distorted, and percent defective is low.
The technical solution of the utility model is: a kind of new hinges volume circle mould, comprise upper bolster, die shoe, upper die and lower die, have holddown groove on the counterdie, patrix is connected in the upper bolster lower surface by compressing rubber blanket, be provided with the shaping slide block on the die shoe, the shaping slide block is connected with counterdie by back-moving spring, and die shoe slides relatively, patrix lower end and shaping upper end of slide block have corresponding deep-slotted chip breaker, the shaping slide block is provided with the inclined-plane away from a side of patrix, and the upper bolster lower surface is provided with the wedge that cooperates with the inclined-plane.
As preferably, described upper bolster and die shoe adopt the Q235 steel to make, and patrix and shaping slide block adopt the GCr15 steel to make, and the upper bolster lower surface is provided with the stop collar with the patrix socket.
As preferably, be provided with the guide plate for the wedge guiding on the die shoe, be provided with the triangle ribs on the guide plate; Have chute on the die shoe, the shaping slide block is slidingly connected in the chute.
The beneficial effects of the utility model are: the utility model adopts patrix and shaping slide block jointly to finish the shaping of volume circle part, be provided with the compression rubber blanket on the patrix, add man-hour, volume circle part is put into the holddown groove of counterdie, upper bolster is descending with forcing press, wedge contacts with the shaping slide block, and the shaping slide block is moved to the direction near counterdie, jointly finishes the shaping of rolling up the circle part with patrix, plastic force is large, volume circle quality is good, and volume circle part is difficult for distorted, and percent defective is low.Guide plate has guaranteed the kinematic accuracy of wedge, and back-moving spring helps the shaping slide block to reset, and waits for next time being shaped, and is very convenient and practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As a kind of embodiment of the present utility model, as shown in Figure 1, a kind of new hinges volume circle mould, comprise upper bolster 6, die shoe 1, patrix 5 and counterdie 11, in the present embodiment, as preferably, described upper bolster 6 and die shoe 1 adopt the Q235 steel to make good combination property, long service life.Patrix 5 and shaping slide block 3 adopt the GCr15 steel to make, and intensity is high, and is not fragile.Have holddown groove on the counterdie 11, holddown groove is used for fixing volume circle part 9.Patrix 5 is connected in upper bolster 6 lower surfaces by compressing rubber blanket 7, as preferably, has blind hole on the patrix 5, compresses rubber blanket 7 and is arranged in the blind hole.Compress the pressure that rubber blanket 7 can increase 5 pairs of volume circles of patrix part 9, improve the quality of volume circle part 9.Be provided with shaping slide block 3 on the die shoe 1, shaping slide block 3 is connected with counterdie 11 by back-moving spring 10, and die shoe 1 slides relatively, as preferably, shaping slide block 3 sidewalls have blind hole, back-moving spring 10 is arranged in the blind hole, and back-moving spring 10 can make shaping slide block 3 get back to initial position after the volume circle is finished.Patrix 5 lower ends and shaping slide block 3 upper ends have corresponding deep-slotted chip breaker, and shaping slide block 3 is provided with the inclined-plane away from a side of patrix 5, and upper bolster 6 lower surfaces are provided with the wedge 4 that cooperates with the inclined-plane.
In the present embodiment, as preferably, upper bolster 6 lower surfaces are provided with the stop collar 8 with patrix 5 sockets, and stop collar 8 can avoid patrix 5 to break away from the operating position under the effect that compresses rubber blanket 7, guarantees the positional precision of patrix 5.Be provided with the guide plate 2 for wedge 4 guiding on the die shoe 1, guide plate 2 can guarantee the displacement accuracy of wedge 4.Be provided with the triangle ribs on the guide plate 2; Avoid guide plate 2 occurred level play under the effect of wedge 4.Have chute on the die shoe 1, shaping slide block 3 is slidingly connected in the chute.
The course of work of the present utility model is as follows: add man-hour, volume circle part 9 is put into the holddown groove of counterdie 11, upper bolster 6 is descending with forcing press, and wedge 4 contacts with shaping slide block 3, shaping slide block 3 is moved to the direction near counterdie 11, jointly finish the shaping of rolling up circle part 9 with patrix 5.
