Abstract
The utility model discloses a rolling and bending die provided with core rods, and relates to a stamping die. The rolling and bending die comprises an upper die base, a lower die base and an upper die, wherein the upper die is connected with the lower surface of the upper die base movably through a pressure spring; forming blocks are arranged in positions, corresponding to the upper die, on two sides of the lower die base respectively and can glide relative to the lower die base; arc-shaped grooves used for forming a rolled part are formed in corresponding positions of opposite surfaces of the forming blocks and the upper die respectively; a reset mechanism is arranged on each forming block; an inclined plane is arranged at one end, far from the upper die, of each forming block; inclined wedges matched with the inclined planes of the forming blocks are arranged on two sides of the lower surface of the upper die base respectively; and the rolling and bending die also comprises the core rods arranged inside arcs at two ends of the rolled circle part. According to the utility model, two ends of a hinge can be rolled by one step, the production efficiency is high, repeat positioning is not required, the pressure on the rolled part is large, the rolled part cannot be distorted easily, the rejection rate is low, the quality of inner walls of the rolled part is good, and the rolling and bending die is very practical.
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 during Modern Industry Products, automobile, electrical equipment, instrument and instrument are made, quantity is maximum.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 is generally 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 patrix, be provided with compact heap on counterdie, during shaping, workpiece is placed between counterdie and 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, be all 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, can the once-forming hinge volume circle at two ends, production efficiency is high, needn't resetting, and 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, very practical.
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 holddown spring, the position corresponding with patrix, die shoe both sides is respectively arranged with the shaping piece, shaping piece die shoe relatively slides, on shaping piece and patrix face toward each other, corresponding position is respectively arranged with the deep-slotted chip breaker for the volume circle part that is shaped, be provided with resetting-mechanism on the shaping piece, the shaping piece is provided with the inclined-plane away from a side of patrix, upper bolster lower surface both sides are respectively arranged with the wedge that coordinates with the piece inclined-plane of being shaped, also comprise and be arranged at the interior plug of volume circle part two ends circular arc.
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 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 first carry out 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 shaping piece of both sides and patrix are completed the volume circle shaping at hinge two ends jointly, production efficiency is high, needn't resetting, improved the precision of product, reduced percent defective.Volume bowlder holddown spring 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, 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 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 holddown spring 8, as preferably, has blind hole on patrix 9, and holddown spring 8 is arranged in blind hole.During shaping, patrix 9 compresses volume circle part 10 under the effect of holddown spring 8, improves the quality of volume circle part 10.
The position corresponding with patrix 9, die shoe 1 both sides is respectively arranged with shaping piece 4, shaping piece 4 die shoe 1 relatively slides, on shaping piece 4 and patrix 9 face toward each other, corresponding position is respectively arranged with the deep-slotted chip breaker for the volume circle part 10 that is shaped, be provided with resetting-mechanism on 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 coordinates with piece 4 inclined-planes of being 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.
