Description
Technical Field
The utility model belongs to the technical field of the mould, a car window frame sheet metal component many blank pressing circle is synchronous presses automatic transmission mould of material is related to.
Background
At present, in the stretching process of a sheet metal part of an automobile window frame, the thickness of a deformation mass point on a flange area is changed continuously, so that the deformation state of the deformation mass point is different, and the required blank holding force is also different in the drawing process. The whole edge pressing method can only ensure that the edge pressing ring is contacted with the thickest part of deformation particles of the plate, and the edge pressing effect is not ideal. At present, circumferential blocking and edge pressing are mostly adopted, and the method is to divide the edge pressing ring into a plurality of blocks along the circumferential direction so as to respectively implement edge pressing force control on a straight edge area and a fillet area. The method solves the problem that the effective blank pressing cannot be implemented on the whole deformation area due to the fact that the thickness of the plate material in the deformation area is not uniformly distributed along the circumferential direction. However, in the fillet area of the sheet metal part of the automobile window frame, the plate thickness is also changed along the radial direction (pointing to the direction of the die opening), and the edge pressing effect is still not ideal because the edge pressing cannot be respectively performed on different deformation particles along the radial direction by a simple circumferential block edge pressing method.
In order to overcome the defects of the prior art, people continuously explore and provide various solutions, for example, a chinese patent discloses a stamping die for sheet metal parts [ application number: 201210146933.2], including the die carrier that cope match-plate pattern, lower bolster, guide pillar, guide pin bushing, punch plate and die holder are constituteed, characterized by: the die comprises a male die fixed on a male die fixing plate, a first female die block and a second female die block fixed on a female die fixing plate, wherein a groove matched with the male die is formed between the first female die block and the second female die block; and a material pressing device is also arranged on the male die fixing plate. The beneficial effects of the invention are as follows: the pressing device presses the rest part of the material plate except the blanking position, so that the material plate is kept flat and does not tilt, multiple blanking operations are facilitated, and the quality of a final workpiece is improved; the slide way on the side wall of the concave module limits the position of the sheet metal material plate and forms a moving track of the material plate. However, the scheme still cannot perform edge pressing on different radial deformation particles respectively, and has the defect of unsatisfactory edge pressing effect.
