Abstract

The utility model discloses a flip drawing die with a pressure plate and relates to a stamping die. The die comprises an upper die seat, a lower die seat and a die handle, wherein a guide sleeve is arranged on the lower surface of the upper die set, a guide post which is matched with the guide sleeve is arranged on the upper surface of the lower die seat, a drawing punch is arranged on the upper surface of the lower die seat, a drawing die is arranged at a position of the lower surface of the upper die seat, which corresponds to the drawing punch, a knocking rod is arranged in the die hole of the drawing die, the lower end of the knocking rod is connected to the pressure plate, the upper end of the knocking rod penetrates into the upper end face of the die handle to be connected to an ejecting device, the pressure plate can slide relative to the die hole, a discharging plate is sleeved outside the drawing punch, the discharging plate is connected to the lower die seat through a discharging screw in a moving mode, a rubber cushion is sleeved outside the discharging screw, and an annular boss which is sleeved on the drawing punch in an annular mode is arranged on the upper surface of the discharging plate. By the aid of the drawing die, the pressure force on workpieces is high, the workpiece surface quality is good, workpieces are not easy to crinkle, the rejection rate is low, workpieces can be taken out from the drawing die easily after the drawing is completed and the working efficiency is improved.

Description

Upside-down mounting Drawing Die with holding pad
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of upside-down mounting Drawing Die with holding pad.
Background technology
Pull and stretch is a kind of common mechanical processing technique, is the process for stamping and forming of making cup shell of the plane slab, claims again to draw.Can make the hollow object of cylindrical shape, sphere, taper, box-like, stairstepping, flanged and other complicated shapes by pull and stretch.Its shaping generally is to finish by Drawing Die, when using existing Drawing Die to carry out drawing and forming, mould is less to the pressure-plate-force of workpiece, cause surface of the work to crease easily, workpiece surface quality is poor, and percent defective is high, workpiece behind the pull and stretch is stuck in the pull and stretch die easily in addition, be difficult for taking out, reduced operating efficiency, even cause that mould damages.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of upside-down mounting Drawing Die with holding pad, and is large to the pressure-plate-force of workpiece, workpiece surface quality is good, does not crease easily, and percent defective is low, workpiece took out from the pull and stretch die easily after pull and stretch was finished, and had improved operating efficiency.
The technical solution of the utility model is: a kind of upside-down mounting Drawing Die with holding pad, comprise upper bolster, die shoe and die shank, the upper bolster lower surface is provided with guide pin bushing, the die shoe upper surface is provided with the guide pillar that cooperates with guide pin bushing, the die shoe upper surface is provided with the pull and stretch punch, the position that the upper bolster lower surface is corresponding with the pull and stretch punch is provided with the pull and stretch die, be provided with in the die hole of pull and stretch die and make bar, beat the bar lower end and be connected with holding pad, the upper end passes the die shank upper surface and is connected with the bullet apical organ, holding pad relatively die hole slides, the pull and stretch punch is socketed with stripper outward, stripper is flexibly connected by unloading bolt and die shoe, and unloading bolt is socketed with rubber blanket outward, and the stripper upper surface is provided with the annular boss of ring set pull and stretch punch.
As preferably, the pull and stretch punch is up-small and down-big notch cuttype, adopts the GCr15 steel to make, and is provided with lower bolster between pull and stretch punch and the die shoe, and the pull and stretch punch is fixedly connected with lower bolster by punch retainer.
As preferably, be provided with upper padding plate between pull and stretch die and the upper bolster, the pull and stretch die is fixedly connected on the upper padding plate lower surface by die block, and the die hole edge of pull and stretch die is rounded down.
The beneficial effects of the utility model are: be provided with holding pad in the die hole of the utility model pull and stretch die, when drawing and forming, upper bolster is descending with forcing press, holding pad provides enough pressure-plate-forces for workpiece under the effect that plays apical organ, avoid surface of the work wrinkling, guaranteed the surface quality of workpiece, reduced percent defective, after pull and stretch is finished, make bar and under the effect that plays apical organ, reset, workpiece is released in die hole, avoided workpiece to be stuck in the phenomenon that to take out in the die hole, improve operating efficiency, prolonged the mold use life-span.Annular boss on the stripper has further increased pressure-plate-force, has improved workpiece quality.
Description of drawings
Fig. 1 is structural representation of the present utility model.
