Description
Technical Field
The invention relates to a mechanism in the field of automobile part production research, in particular to a movable adjustable clamping and positioning mechanism for a stamping die of a door frame door post plate.
Background
The door frame comprises winding, reinforcing plate, 2 gatepost boards. Under normal conditions, the door post plate is obtained by processing an inner plate and an outer plate through edge wrapping and spot welding, but the door post plate of the aluminum door frame has large strength due to thicker thickness, only has one outer plate, and is overlapped with flanging and edge wrapping. The other surfaces except the surface on the side of the guide groove are all appearance class A surfaces.
The production process of the outer plate of the door post comprises the following steps: OP05 rolling bending to produce a rolled semi-finished product of the outer plate of the door post; OP10 rolling semi-finished product leaf surface trimming; punching the guide groove side of the OP20 semi-finished product; OP30 semi-finished product guide groove side hanging notch; trimming the leaf surface of the OP40 semi-finished product; turning 90 DEG edges of the leaf surfaces of the OP50 semi-finished products; OP60 semi-finished product leaf surface flanging and edge covering.
The stamping die of the door post plate has 6 stations in total, the positioning of the rolling semi-finished product in the horizontal direction in the die is that 2-3 profiling positioning blocks are uniformly distributed on the side of the guide groove, the positioning blocks 10 are fixed on the lower module 11, and the side surface of the guide groove of the lower module 11 is directly kept away; if the whole profiling is performed, the product is a whole surface, the requirement on the product surface is too high, the profiling of the positioning block 10 is difficult to ensure, the other positions are avoided, a cylinder side pressure mechanism is added for ensuring the positioning accuracy in place, the cylinder side pressure mechanism comprises a cylinder 13, a pressing block 15 arranged on the cylinder 13 and a supporting block 12 arranged below the pressing block, and the cylinder 13 is arranged on a fixed seat 14. The support block 12 and the lower module 11 fix the positioning block 10 as shown in fig. 1.
The OP50 is turned over by 90 ° and the OP60 is turned over by 90 ° to form a special-shaped edge, which can be realized technically, but has the problem that after the special-shaped edge is turned over, the product has a negative angle, and cannot be taken out, so that the multi-step special-shaped edge turning is divided.
1) In order to realize the negative angle workpiece taking, the lower module 11 needs to be kept away, the avoiding amount is larger than the negative angle amount, and the width B is larger than the negative angle amount A, so after the stamping is completed, the product is vertically taken out after sliding to the left, but the positioning block 10 is fixed on the lower die, the positioning block 10 cannot be canceled, and the positioning block 10 must be in place when the special-shaped edge is turned, or the negative angle workpiece taking cannot be realized.
2) For the straight-face length C of the opposite side, the tolerance is +/-0.3, the matching assembly is required to adjust to the positive tolerance or the negative tolerance in the later period, the positioning block 10 is required to be loosened in the die cavity, the gasket is increased or decreased for adjustment, the fixing screw of the positioning block 10 is locked in the oblong hole, and along with the importance of production safety, the tool debugging position is required to be avoided in the die cavity. The mold debugging has great potential safety hazard.
