Abstract
The utility model relates to an elastic elastic blank holder device, which is a blank holder device in a metal drawing forming die which is used on a common single-point press, the utility model uses a blank holder bearing plate which outline dimension is same to a blank as a placement location of the blank, thereby guaranteeing a blank holder force not to directly act on the blank in a fixed gap, reducing a blank holder friction force, and guaranteeing that a flange edge portion of a metal part is no wrinkling in a drawing forming production process.
Description
The utility model relates to the flange fixing installation in a kind of metal drawing and shaping mold that uses on common one point press, be a kind of bullet rigid blank holder device that the blank location is reduced flanging frictional force again of being convenient to.
At present, in the processing of metal draw forming, the flange fixing installation of mould has two kinds of forms: rigid blank holder device and elastic blank holding device.The rigid blank holder device only is fit to and double action press, and the elastic blank holding device is used in common one point press.Therefore, add man-hour in the enterprising row metal part drawing shaping of common one point press, be subjected to the restriction of appointed condition, can only use the elastic blank holding device, in the elastic blank holding device, pressure-pad-force directly acts on the made part blank, the change procedure of pressure-pad-force is for from small to large, promptly along with the increase of drawing depth, elastomeric material is (as spring, rubber) compression, pressure-pad-force increases gradually, it is ascending in drawing process to reach pressure-pad-force, descending again variation requirement, the frictional force between blank and the mould also are the increases along with drawing depth, the increase of pressure-pad-force and increasing, increased in the part forming the straight suffered tension of wall force transmission region, caused the vertical wall section attenuation easily or pull open.Simultaneously, for making the blank location, must increase corresponding positioner.
For overcoming the deficiency of elastic blank holding device, the advantage and the principle of the rigid blank holder device that uses in conjunction with double action press, the utility model provides a kind of bullet rigid blank holder device that relies on the gap to guarantee.With with blank shape measure-alike the flanging board as the placement positioning of blank, guarantee that with fixing gap pressure-pad-force does not directly act on the blank, guarantee that metal parts flange brim part in the draw forming production process is wrinkle resistant.
The beneficial effects of the utility model are, and are simple in structure, easy to use.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing 1 is a structure chart of the present utility model.
Accompanying drawing 2 is vertical section structural maps of an embodiment.
In Fig. 1, the working portion of this device is made up of punch (1), die (2), flexible member (3), flanging supporting plate (4), flanging board (5), gap adjustment sheet (6).
In Fig. 2 embodiment, the space that flanging supporting plate (4), flanging board (5), gap adjustment sheet (6) are constituted is the placement and the location of blank, gap adjustment sheet (6) is adjusted the space length between flanging supporting plate (4) and the die (2), guarantee that blank is wrinkle resistant in the draw forming process, when mould is closed, at first, die (2) contacts with flanging board (5), compression elastic element (3), when pressure-pad-force during, come into effect the draw forming production process of part greater than the normal elasticity flange fixing installation.
Claims (2)
1, a kind of novel bullet rigid blank holder device, it is characterized in that: the space that flanging supporting plate (4), flanging board (5), gap adjustment sheet (6) are constituted is the placement and the location of blank.
2, bullet rigid blank holder device according to claim 1 is characterized in that: the space length between gap adjustment sheet (6), adjustment flanging supporting plate (4) and the die (2) guarantees that blank is wrinkle resistant in the draw forming process.
