Abstract
PURPOSE: The hydraulic press for deep drawing work, which is made possible to control the drawing condition like as change of the surface pressure, etc., while the drawing pass for such rectangular body as the bathtub, etc., by varying independently of each other the set pressure of many hydraulic cylinders arranged on the blank holder surface.
CONSTITUTION: In the inner and outer reciprocating hydraulic press, many outer cylinders 2 for executing fine blank-holding are arranged at the outer slide 1. The inner slide 3 is vertically moved by the inner cylinder 4. The inner slide 3 and the outer slide 1 are simultaneously moved down, and the outer slide 1 executes the blank-holding. After that, the inner slide 3 continues its downward motion and executes the drawing work. By the signal being set with the progress of the pass, the pressures of the outer cylinders 2 are respectively independently varied for each position. According to this method, the control of the drawing condition can be executed in such a way of locally giving the tensile rigidity or of uniformizing the residual stress in the material after completion of the drawing work.
