Abstract
The utility model discloses a hem bending mould belongs to tooling, aim at providing the compound mould that a punching press can accomplish hem and bending processing. It includes bed die and formpiston, bed die (4) are fixed on lower bolster (6), have the core of looks adaptation (2) with it in the die cavity of bed die (4), unload rubber pad (7) in the below of lower bolster (6), fix and pass lower bolster (6) and rubber pad (7) the contact of unloading in ejector pin (8) of core (2) bottom surface, with formpiston (1) that the die cavity suited is located bed die (4) top, and there are a tilt up's inclined plane, the top surface of core (2) and the bottom surface looks adaptation of formpiston (1) in the bottom surface of formpiston (1). The utility model discloses not only reduced mould quantity, shortened the process route, improved production efficiency, can guarantee again moreover that the hem is at the accurate butt joint of bending department, product percent of pass height, it a compound mould.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of composite die integrating flanging and bending-forming mold; Belong to technological equipment.
Background technology
Motor shielding box cover is a kind of parts of thin-wall casing roughly in L-shaped, and its two have flange to edge break.Due to complex-shaped, be usually all adopt first flanging again bending two procedures process.Not only die needed many, process route is long, time-consuming, is difficult to the needs meeting large-scale production; And location difficulty during bending, flanging is difficult to accurate docking at bending place, and waster rate is high.
Summary of the invention
For the above-mentioned defect existed in prior art, the utility model aims to provide the flanging bending mould that an a kind of punching press can complete flanging and bending processing.
To achieve these goals, the utility model by the following technical solutions: it comprises former and formpiston; Former is fixed on lower bolster, has core suitable with it in the die cavity of former, and there is discharging rubber blanket the below of lower bolster, and the push rod being fixed on core bottom surface contacts with discharging rubber blanket through lower bolster; The formpiston adapted with described die cavity is positioned at above former, and there is an acclivitous inclined-plane bottom surface of formpiston, the end face of core and the bottom surface of formpiston suitable.
Backing plate is fixed with between former and lower bolster; The surface of former is fixed with location-plate, and this location-plate has locating mould cavity; The side of location-plate offers pickup window.
Compared with the prior art, the utility model, owing to have employed technique scheme, adds core moving up and down in cavity impression, therefore, it is possible to organically combined with bending-forming mold tool by flanging mould, a punching press can realize flanging and bending; Not only reduce number of molds, shorten process route, improve production efficiency, and can ensure that again flanging accurately docks at bending place, product percent of pass is high.

Detailed description of the invention
Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.
As shown in Fig. 1 ~ 5: former 4 is fixed on lower bolster 6, have core 2 suitable with it in the die cavity of former 4, there is discharging rubber blanket 7 below of lower bolster 6, and three push rods 8 being fixed on core 2 bottom surface contact with discharging rubber blanket 7 through lower bolster 6; The formpiston 1 adapted with described die cavity is positioned at above former 4, and the bottom surface of formpiston 1 has one to be inclined upwardly and forms the inclined-plane of hammer shape, the end face of core 2 and the bottom surface of formpiston 1 suitable.
For the ease of protection former 4, between this former and lower bolster 6, be fixed with backing plate 5.
For the ease of location, be fixed with location-plate 3 on the surface of former 4, this location-plate have locating mould cavity (not indicating in figure).
For the ease of the taking-up workpiece 9 of safety, offer pickup window 10 in the side of location-plate 3.
