Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of volume circular bending mould of cored bar.
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.Once can only the be shaped volume circle of hinge one end of existing volume circle mould during the processing other end, need to take out workpiece, changes an end and again is shaped, production efficiency is low, and the workpiece positioning accuracy is poor, and percent defective is high, the pressure-plate-force of existing volume circle mould is little in addition, the easy distorted of volume circle part, and the volume circle is of poor quality.When existing volume circle mould volume circle is shaped, all be the outer wall of direct effect and volume circle, the inwall of volume circle does not have to support, and therefore volume circle inwall is of poor quality, can not be applied to have rolling up round internal diameter the occasion of tolerance.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of volume circular bending mould of cored bar, volume circle that can once-forming hinge two ends, production efficiency is high, needn't resetting, large to the pressure-plate-force of rolling up round part, volume circle part is difficult for distorted, percent defective is low, and volume circle inwall quality is good.
The technical solution of the utility model is: a kind of volume circular bending mould of cored bar, comprise upper bolster, die shoe and patrix, 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 relatively die shoe 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, be provided with resetting-mechanism on the shaping piece, 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 horizontally disposed back-moving spring, 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 first pre-bending, then put into the shaping piece, 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, production efficiency is high, 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 distorted, 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.
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 volume circular bending mould of cored bar, comprise upper bolster 7, die shoe 1 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.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.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.
Die shoe 1 both sides and patrix 9 corresponding positions are respectively arranged with shaping piece 4, shaping piece 4 relatively die shoe 1 slides, corresponding position is respectively arranged with the deep-slotted chip breaker for the volume circle part 10 that is shaped on shaping piece 4 and patrix 9 face toward each other, be provided with resetting-mechanism on the shaping piece 4, in the present embodiment, as preferably, shaping piece 4 lower ends are connected with release link 2, die shoe 1 upper surface has rectangular channel, and release link 2 lower ends are positioned at rectangular channel and are connected with the rectangular channel sidewall by horizontally disposed back-moving spring 12.Shaping piece 4 is provided with the inclined-plane away from a side of patrix 9, and upper bolster 7 lower surface both sides are respectively arranged with the wedge 5 that cooperates with piece 4 inclined-planes that are shaped; Also comprise being arranged at the interior plug 11 of volume circle part 10 two ends circular arcs, the volume circle inwall that plug 11 can help to be shaped and roll up circle part 10 improves the precision of rolling up round part 10.
