Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of novel 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, counterdie is provided with compact heap, during shaping workpiece is placed between counterdie and the compact heap, patrix is descending, and workpiece rolls to shape at the deep-slotted chip breaker of pressured state lower edge patrix.Once can only the be shaped volume circle of hinge one end of existing volume circle mould during the processing other end, need take out workpiece, changes an end and is shaped again, production efficiency is low, and the workpiece positioning accuracy is poor, the percent defective height, the pressure-plate-force of existing volume circle mould is little in addition, and volume circle part distorts easily, and the volume circle is of poor quality.During round shaping of existing volume circle mould volume, all be directly effect and the outer wall of rolling up circle, the not support of the inwall of volume circle, therefore volume circle inwall is of poor quality, and can not be applied to has the occasion of tolerance to rolling up round internal diameter.
Summary of the invention
Problem at above-mentioned prior art existence, the utility model provides a kind of novel volume circle mould, volume circle that can once-forming hinge two ends, the production efficiency height needn't resetting, and is big to the pressure-plate-force of rolling up round part, volume circle part is difficult for distorting, percent defective is low, and volume circle inwall quality is good, very practical.
The technical solution of the utility model is: a kind of novel volume circle mould, comprise upper bolster, die shoe, die shank and patrix, the upper bolster lower surface is provided with guide pin bushing, the die shoe upper surface is provided with the guide pillar that cooperates with guide pin bushing, patrix is movably connected on the upper bolster lower surface by compressing rubber blanket, the position corresponding with patrix, die shoe both sides is respectively arranged with the shaping piece, shaping piece die shoe relatively slides, corresponding position is respectively arranged with the deep-slotted chip breaker for the volume circle part that is shaped on shaping piece and the patrix face toward each other, the shaping piece is provided with resetting-mechanism, the shaping piece is provided with the inclined-plane away from a side of patrix, and upper bolster lower surface both sides are respectively arranged with the wedge that cooperates with the piece inclined-plane that is shaped; Also comprise the plug that is arranged in the circular arc of volume circle part two ends.
As preferably, shaping piece lower end is connected with release link, and the die shoe upper surface has rectangular channel, and the release link lower end is positioned at rectangular channel and is connected with the rectangular channel sidewall by the horizontally disposed rubber blanket that resets, and is provided with slide plate between shaping piece and the die shoe.
As preferably, described upper bolster and die shoe adopt the Q235 steel to make, and patrix and shaping piece adopt the GCr15 steel to make, and the upper bolster lower surface is provided with the stop collar with the patrix socket, but patrix relative limit cover is mobile.
The beneficial effects of the utility model are: the utility model counterdie both sides are respectively arranged with the shaping piece, add man-hour, will roll up the circle part and carry out pre-bending earlier, put into the shaping piece then, plug is inserted in the circular arc at volume circle part two ends, upper bolster is descending, and wedge moves horizontally the shaping piece, and the volume circle that the shaping piece of both sides and patrix are finished the hinge two ends jointly is shaped, the production efficiency height, needn't resetting, improved the precision of product, reduced percent defective.The volume bowlder compresses rubber blanket can provide enough pressure-plate-forces, and volume circle quality is good, and volume circle part is difficult for distorting, and percent defective is low.Plug can help to be shaped and roll up the volume circle inwall of justifying part, has guaranteed the quality of inwall, and is very 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 novel volume circle mould, comprise upper bolster 7, die shoe 1, die shank and patrix 9, in the present embodiment, as preferably, described upper bolster 7 and die shoe 1 adopt the Q235 steel to make good combination property, long service life.Die shank adopts 45 steel to make, and die shank presses fit in the upper bolster 7.Upper bolster 7 lower surfaces are provided with guide pin bushing, and die shoe 1 upper surface is provided with the guide pillar that cooperates with guide pin bushing, has improved guiding accuracy of the present utility model.Patrix 9 is movably connected on upper bolster 7 lower surfaces by compressing rubber blanket 8, as preferably, has blind hole on the patrix 9, compresses rubber blanket 8 and is arranged in the blind hole, compresses rubber blanket 8 upper ends and is connected with die shank, and the lower end is connected with patrix 9.Patrix 9 compresses volume circle part 10 during shaping under the effect that compresses rubber blanket 8, improves the quality of volume circle part 10.
