[Detailed description of the invention] A. Field of industrial application The invention is used in a press machine that presses sheet metal such as steel plate into various shapes, and is particularly applicable to press-forming sheet metal into various shapes using a punch provided in the upper die. Tsute Sendan,
The present invention relates to a press die that allows a punch to protrude from the lower die when bending or drawing, making it possible to simultaneously press the front and back surfaces of a sheet metal.

B. Prior art Each part that makes up an automobile body is molded into a desired shape through various processes using press working, but if the processed shape protrudes from the front and back of the sheet metal, press working from the front side is required. The pressing from the back side is done in a separate process. For example, press processing for the inside of a door involves drawing the entire shape of the steel plate, punching out the outer shape, and partial punching to punch out unnecessary parts.
The drawing process to form a reverse embossed shape was performed in a separate process from a direction opposite to these processing directions.

Therefore, it is necessary to prepare a special mold for reverse embossing performed from the opposite direction, and the number of man-hours also increases. Here, in particular, when pressing from the opposite direction, such as forming a reverse embossed shape, is done only partially on the workpiece, there is a problem in terms of production rationalization, even though the utilization rate of the press equipment is low.

C. Purpose of the invention The present invention was made in view of the above-mentioned conventional problems and to improve them. An object of the present invention is to provide a press die in which a punch can be applied simultaneously from both an upper die and a lower die, thereby reducing the number of car bodies and processes.

First, the workpiece 3 is drawn into a steel plate and formed into a predetermined shape by performing press processing such as external die cutting, and then the lower mold 4
Align and place it on top. After that, the workpiece holding member 2 is lowered and works together with the lower mold 4 to hold the workpiece 3.
to hold. At this time, the forming surface 2b' of the forming punch 2b does not come into contact with the workpiece 3, but faces it with a predetermined distance therebetween. Thereafter, the upper mold 1 is lowered to a position where it comes into contact with the workpiece holding member 2 as shown in the figure.
Then, the punch 1a removes the unnecessary part 3a of the workpiece 3.
At the same time, the first cam member 6 fixed to the upper mold 1 is lowered, and the first cam member 6 is punched out.
The horizontal movement of the second cam member 7 (leftward in the drawing) which is in sliding contact with the tapered surfaces 6a and 7b, and the upward movement of the reverse embossing punch 5 which is in sliding contact with the second cam member 7 and the tapered surfaces 7a and 5b are simultaneously performed, The convex molding surface 5a of the reverse embossing punch 5 presses the workpiece 3 against the concave molding surface 2b' of the molding punch 2b, whereby a reverse embossing 3b is formed on the workpiece 3. After this, when the upper mold 1 is raised, the second cam member 7 is horizontally moved (rightward in the drawing) by the return spring 11 and returned, and the reverse embossing punch 5 is separated from the workpiece 3. Further, the work holding member 2 is raised to take out the molded work 3.
