Abstract
The utility model discloses a composite bending die and relates to a bending die. The composite bending die comprises an upper die seat, a lower die seat and a die handle, wherein a concavo-convex die is arranged on the lower surface of the upper die seat; a run-through bending hole is formed in the concavo-convex die; a bending female die is arranged on the upper surface of the lower die seat and at the position corresponding to the concavo-convex die; a moveable male die is arranged in a female die hole of the bending female die and at the position corresponding to the bending hole; the moveable male die consists of a bottom plate and a boss arranged on the upper surface of the bottom plate; the bottom plate is in clearance fit with the female die hole; the boss is matched with the bending hole; the lower surface of the bottom plate is connected with a mandril; and the lower end of the mandril is connected with a lift spring. Blank can be bent for twice in one set of die, so the composite bending die has high work efficiency, low labor intensity of workers, does not need resetting, improves the precision of the product, reduces the rejection rate, and is very practical.
Description
Technical field
The utility model relates to a kind of bending mould, relates in particular to a kind of composite bending die.
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.the crooked part major part adopts bending die to process, existing bending die comprises punch and the die of steel, punch moves down under the drive of forcing press, workpiece is completed brake forming under the acting in conjunction of punch and die, shape matching complexity when bool, for example will be with the dual-side bending laterally again of U-shaped spare, can only use two molds, first in a mold, blank is bent to U-shaped, put into again another set of mould, the dual-side of outwardly-bent U-shaped spare, inefficiency like this, increased workman's labour intensity, want resetting in addition in two molds, affected the precision of product, increased percent defective.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provides a kind of composite bending die, can complete twice bending of blank in a mold, high efficiency, workman's labour intensity is low, does not need resetting, has improved the precision of product, reduced percent defective, very practical.
the technical solution of the utility model is: a kind of composite bending die, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with punch-die, have the flexure type hole of perforation on punch-die, the position that the die shoe upper surface is corresponding with punch-die is provided with bending die, position corresponding with the flexure type hole in the die hole of bending die is provided with movable punch, movable punch is comprised of base plate and the boss that is arranged at plate upper surface, base plate and die hole matched in clearance, boss and flexure type hole coupling, the base plate lower surface is connected with push rod, the push rod lower end is connected with the head part spring.
As preferably, flexure type is provided with holding pad in the hole, and holding pad flexure type hole relatively moves up and down, and the holding pad upper end is connected in upper bolster by making bar, beats bar and upper bolster matched in clearance.
As preferably, bending die upper surface both sides are respectively arranged with locating piece, and punch-die is connected with the upper bolster lower surface by fixed head, is provided with backing plate between punch-die and upper bolster.
the beneficial effects of the utility model are: have the flexure type hole on punch-die of the present utility model, be provided with movable punch in bending die, when using the utility model bending machining, blank is placed on the bending die surface, punch-die moves down under upper bolster drives, blank bends to U-shaped under the effect of punch-die outer wall and bending die die hole, then punch-die continues descending, blank contraflexure under the effect in movable punch and flexure type hole becomes net shape, can complete twice bending like this in a mold, high efficiency, workman's labour intensity is low, and do not need resetting, improved the precision of product, reduced percent defective, 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 composite bending die, comprise upper bolster 6, die shoe 1 and die shank, in the present embodiment, as preferably, upper bolster 6, die shoe 1 and die shank all adopt 45 steel to make, and die shank presses fit into upper bolster 6 upper surfaces.Upper bolster 6 lower surfaces are provided with punch-die 8, have the flexure type hole of perforation on punch-die 8, the position that die shoe 1 upper surface is corresponding with punch-die 8 is provided with bending die 11, position corresponding with the flexure type hole in the die hole of bending die 11 is provided with movable punch 2, movable punch 2 is comprised of base plate and the boss that is arranged at plate upper surface, base plate and die hole matched in clearance, and mate in boss and flexure type hole, the base plate lower surface is connected with push rod 12, and push rod 12 lower ends are connected with the head part spring.Push rod 12 can provide enough pressure when bending, guarantee the quality of product.In the present embodiment, as preferably, die hole is up-small and down-big shoulder hole, and die hole upper end open edge is rounded down.
In the present embodiment, as preferably, flexure type is provided with holding pad 9 in the hole, and holding pad 9 flexure type hole relatively moves up and down, and holding pad 9 upper ends are connected in upper bolster 6 by making bar 7, beat bar 7 and upper bolster 6 matched in clearance.Holding pad 9 can compress blank 10 when bending, avoid bool wrinkling.
In the present embodiment, as preferably, bending die 11 upper surface both sides are respectively arranged with locating piece 3, facilitate the location of blank 10.Punch-die 8 is connected with upper bolster 6 lower surfaces by fixed head 4, is provided with backing plate 5 between punch-die 8 and upper bolster 6, and backing plate 5 can avoid 8 pairs of upper bolsters 6 of punch-die directly to impact, and has extended the service life of upper bolster 6.
Above a kind of composite bending die provided by the utility model has been carried out detailed introduction, used specific case herein principle of the present utility model and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present utility model and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.To be possible to change of the present utility model and improvement, and can not exceed design and the scope that accessory claim can be stipulated.
