Abstract

The utility model discloses a twice-bending composite bending die, and relates to a bending die. The twice-bending composite die comprises an upper die seat, a lower die seat and a die handle. The lower surface of the upper die seat is provided with a punch die which is provided with a through curved hole. The position of the upper surface of the lower die seat, corresponding to the punch-die, is provided with a bending concave die. A movable convex die is arranged at the position inside a concave die hole of the bending concave die, corresponding to the curved hole. The movable convex die is composed of a bottom plate and a boss which is arranged on the upper surface of the bottom plate, the bottom plate is in clearance fit with the concave doe hole, and the boss is matched with the curved hole. The lower surface of the bottom plate is connected with a mandril, and the lower end of the mandril is connected with a head part rubber pad. According to the twice-bending composite die, twice bending of blanks can be finished in one set of dies, working efficiency is high, the labor intensity of workers is low, repeated positioning is of no need, the precision of products is improved, and defective index is lowered.

Description

Twice crooked composite bending die
Technical field
The utility model relates to a kind of bending mould, relates in particular to a kind of twice crooked composite bending die.
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.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 finished brake forming under the acting in conjunction of punch and die, shape matching complexity when bool, for example will be with the more laterally bending of dual-side of U-shaped spare, then can only use two molds, in a mold, blank be bent to U-shaped first, put into again another set of mould, the dual-side of outwardly-bent U-shaped spare, such inefficiency has increased workman's labour intensity, wants resetting in addition in two molds, affect the precision of product, increased percent defective.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of twice crooked composite bending die, can finish twice bending of blank in a mold, high efficiency, workman's labour intensity is low, does not need resetting, improve the precision of product, reduced percent defective.
The technical solution of the utility model is: a kind of twice crooked 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 the punch-die, the position that the die shoe upper surface is corresponding with punch-die is provided with bending die, the position corresponding with the flexure type hole is provided with movable punch in the die hole of bending die, 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, and the push rod lower end is connected with the head part rubber blanket.
As preferably, flexure type is provided with holding pad in the hole, and holding pad relatively flexure type hole moves up and down, and the holding pad upper end is connected in the 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 the upper bolster.
The beneficial effects of the utility model are: have the flexure type hole on the punch-die of the present utility model, be provided with movable punch in the 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, in a mold, can finish twice bending like this, high efficiency, workman's labour intensity is low, and does not need resetting, has 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 twice crooked 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 the punch-die 8, die shoe 1 upper surface and punch-die 8 corresponding positions are provided with bending die 11, the position corresponding with the flexure type hole is provided with movable punch 2 in the die hole of bending die 11, 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, boss and flexure type hole coupling, the base plate lower surface is connected with push rod 12, and push rod 12 lower ends are connected with the head part rubber blanket.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, be provided with holding pad 9 in the flexure type hole, holding pad 9 relatively flexure type hole moves up and down, and holding pad 9 upper ends are connected in the upper bolster 6 by making bar 7, beats 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, make things convenient for 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 the upper bolster 6, and backing plate 5 can avoid 8 pairs of upper bolsters 6 of punch-die directly to impact, and has prolonged the service life of upper bolster 6.
The above only is a kind of embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and obvious mode of texturing etc., all should be included within the protection domain of the present utility model.
