Brief introduction of drawing press for stamping equipment

Drawing presses for stamping equipment Double-action drawing presses are currently commonly used thin plate drawing presses. When drawing sheet parts on a double-action drawing press, the lower die is a concave die and the upper die is a convex die. The blank holder force is generated by the outer slider (also called the holder slider), when the inner slider (Also known as deep drawing slider) When deep drawing, the outer slider presses the periphery of the blank. The deep-drawn parts of complex shapes deform unevenly along the periphery, which requires the installation of deep-drawn ribs in different blank holder sections to form a deformation condition for uniform metal flow. At the beginning of blanking on the double-action drawing press of the stamping equipment, the outer sliding block is already at the limit position, so the contact is relatively stable and there is no dynamic load caused by impact. The lower die (concave die) of the double-action press is fixed on the worktable, and the blank is easy to place and position. The return stroke of the outer slide of the double-action drawing press of the stamping equipment is slightly lagging behind the return stroke of the inner slide to ensure that the workpiece is pushed from the middle of the die to the plane of the lower die at the end of drawing.
