Description
Technical Field
The utility model relates to a die-cut blanking mould of bilateral symmetry thin wall spare.
Background
When the left and right symmetrical thin-walled pieces are punched and blanked, the direct stress position of the pieces contacting steel materials at the beginning of punching is a bright belt, and otherwise, a tearing belt appears on the other side. When the material sheet is subsequently bent and formed, the surface of the part is not cracked and is not easy to crack due to the bright band at the bent part with the notch of the workpiece. After bending, the cracked side needs to be manually polished. However, manual sanding wastes labor cost, time and labor.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the technical problem that will solve is: the punching blanking die for the thin-walled workpiece is capable of preventing the blanked part from cracking during bending forming.
For solving the technical problem, the utility model discloses the technical scheme who adopts does: a punching and blanking die for thin-walled parts which are bilaterally symmetrical comprises an upper die base and a lower die base, wherein a feeding guide block is arranged on the lower die base, side guide blocks are respectively arranged on two sides of the feeding guide block, three machining stations are arranged on the lower die base along the feeding direction, a positioning die button for forming a pair of positioning holes is arranged on the first machining station on the lower die base, a positioning punch matched with the positioning die button is arranged on the upper die base, punching die buttons for machining hole positions on workpieces are arranged on the first machining station on the lower die base, and a punching punch matched with the punching punch is arranged on the upper die base; a notch die button for punching the notch is arranged at the bent part with the notch of the left workpiece, which corresponds to the left workpiece which does not need to be turned during the forming processing after punching, on the lower die base, and a matched notch cutter block is arranged on the upper die base; a left forming die button of a left workpiece which does not need to be turned over during forming processing after punching is arranged on the second processing station on the lower die holder, and a left forming cutter block matched with the upper die holder is arranged on the upper die holder; and a right forming die button of a right workpiece needing to be turned over during punching and forming machining is arranged on the third machining station on the lower die holder, and a matched right forming cutter block is arranged on the upper die holder.
As a preferable scheme, a discharging guide plate is arranged on the discharging side of the lower die holder.
As a preferred scheme, a left material guide plate for guiding out the punched materials is arranged below the left forming die button on the lower die base; a right guide plate for guiding out the punched materials is arranged below the right forming die button on the lower die base.
The utility model has the advantages that:
the plate is punched with a notch at the position where the plate is easy to crack and falls off, the upper surface of the notch of the product is provided with a bright belt, then the whole part is punched, and the position where the plate is easy to crack does not crack any more during subsequent bending. The problem of turn-ups fracture scrap highly is solved, manpower and materials have been saved, have guaranteed the fashioned stability of part.
Because the discharging guide plate is arranged on the discharging side of the lower die base, the discharging of the residual material plate after blanking is facilitated.
A left material guide plate for guiding out the punched materials is arranged below the left forming die button on the lower die base; and a right guide plate for guiding the punched materials is arranged below the right forming die button on the lower die base, so that the cut materials can be output conveniently.
