Abstract
The utility model discloses a drawing mould with an under-mounted convex mould, and relates to a stamping mould. The drawing mould with the under-mounted convex mould comprises an upper mould base, a lower mould base and a mould handle, wherein a guide sleeve is arranged on the lower surface of the upper mould base; a guide post matched with the guide sleeve is arranged on the upper surface of the lower mould base; a drawing convex mould is arranged on the upper surface of the lower mould base; a drawing concave mould is arranged on the lower surface of the upper mould base and at a position corresponding to the drawing convex mould; a beating rod is arranged in a concave mould hole of the drawing concave mould; a material pressing plate is connected to the lower end of the beating rod; the upper end of the beating rod penetrates out of the upper end surface of the mould handle and is connected with a propping device; the material pressing plate can slide relative to the concave mould hole; a discharging plate is sleeved outside the drawing convex mould; the discharging plate is movably connected with the lower mould base through a discharging screw; a discharging spring is sleeved outside the discharging screw; and an annular lug boss for encircling the drawing convex mould is arranged on the upper surface of the discharging plate. The drawing mould with the under-mounted convex mould has a workpiece pressing force; workpieces are good in surface quality, are not likely to wrinkle and are low in unqualified rate; after drawing, the workpieces can be easily taken out from the drawing concave mould, so that the working efficiency is improved; therefore, the drawing mould with the under-mounted convex mould is very practical.
Description
Technical field
The utility model relates to a kind of diel, relate in particular to a kind of punch under Drawing Die.
Background technology
Pull and stretch is a kind of common mechanical processing technique, is to make the process for stamping and forming of cup shell of the plane slab, claims again to draw.Can make the hollow object of cylindrical shape, spherical, taper, box-like, stairstepping, flanged and other complicated shapes by pull and stretch.Its shaping is generally to complete 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 after pull and stretch easily is stuck in the pull and stretch die in addition, be difficult for taking out, reduced operating efficiency, cause that even mould damages.
Summary of the invention
Problem for above-mentioned prior art existence, the utility model provide a kind of punch under Drawing Die, pressure-plate-force to workpiece is large, workpiece surface quality is good, do not crease easily, percent defective is low, and after pull and stretch is completed, workpiece easily takes out from the pull and stretch die, improved operating efficiency, very practical.
the technical solution of the utility model is: a kind of punch under Drawing Die, 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 coordinates 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 plays apical organ and be connected, holding pad die hole relatively slides, the pull and stretch punch is socketed with stripper outward, stripper is flexibly connected by unloading bolt and die shoe, unloading bolt is socketed with the discharging spring outward, 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 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 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 completed, make bar and reset under the effect that plays apical organ, workpiece is released in die hole, avoided workpiece to be stuck in the phenomenon that to take out in die hole, improve operating efficiency, extended the mold use life-span.Annular boss on stripper has further increased pressure-plate-force, has improved workpiece quality, and is very practical.
Description of drawings
Fig. 1 is structural representation of the present utility model.
