(Prior art) Set a panel work having a vertical wall on the punch attached to the lower die, provide a cam slide equipped with a tool for press working on the side of the punch, and attach the cam slide to the upper die. A press die has been already developed, which is driven forward by the downward movement of the cam driver and presses the vertical wall of the panel work by the cooperation of the cam slide and the punch (for example, see Japanese Utility Model Publication No. 62-109815). .

(Problems to be Solved by the Invention) According to the above-mentioned conventional press die, the cam slide provided on the side of the punch is driven forward by the cam driver that descends as the upper die descends. The vertical wall can also be pressed. However, in the case of pressing two places where the press working positions are close to each other and the inclination angles of the cam driver receiving surfaces of the cam slides are different, it cannot be achieved by one set of cam slide and cam driver, and two sets of cam slide and cam drive However, it is difficult to secure a space. Therefore, a separate step for driving each cam slide is required, which causes an increase in press working time and a rise in manufacturing cost.

Therefore, an object of the present invention is to enable press work on a panel work in one step even when press work is performed on two locations that are close to each other and have different inclination angles of the cam driver receiving surfaces of the cam slides. It is to provide a press die that can reduce the manufacturing cost and the manufacturing cost.

(Means for Solving the Problems) A press die of the present invention that achieves the above object is attached to a lower die, a punch capable of setting a panel work, and a punch disposed on the side of the punch and attached to an upper die. Mounted on a lower die, which is located in the vicinity of the first cam slide and is provided with a tool that is driven forward by the first cam driver and presses the panel work in cooperation with the punch. A second cam slide which is driven forward by a second cam driver and presses a panel work in cooperation with a punch, and a second cam slide attached to the upper mold, Two cam drivers corresponding to the above-mentioned second cam driver in which the two-cam driver is divided into two and is provided in the lower mold by sandwiching the first cam slide, and the second cam slide is divided into two. The first cam driver is divided into two pieces, the first cam driver is divided into two pieces, and the first cam slide is divided into two pieces, and the first cam slide piece is divided into two pieces. This is also achieved by a press die having two cam driver receiving surfaces corresponding to one cam driver.

(Operation) The panel work is pressed by the cooperation of the first cam slide, which is driven forward by the first cam driver that descends as the upper die descends, and the punch. Pressing is performed by the cooperation of the punch and the second cam slide that is driven forward by the second cam driver that approaches with the descending.

Embodiment An embodiment of the press die of the present invention will be described below with reference to the drawings.

It is a line sectional view.

In the figure, reference numeral 1 is a lower die, and 2 is an upper die which is provided so as to face the lower die and which is vertically moved by vertical drive means (not shown). The lower die 1 is provided with a punch 1a capable of setting a panel work w, and first cam slides 3 are provided on the sides of the punch 1a at front and rear portions of both sides of the first cam slide 3, respectively. The sliding pieces 3a, 3a, 3a, 3a and the guide portions 1b, 1b, 1b, 1b (shown only in FIG. 3) provided on the lower mold 1 are slidably engaged with each other, and with respect to the punch 1a. It is reciprocally supported in the contacting / separating direction A and is constantly urged by a spring (not shown) in a direction of separating from the punch 1a. A front end 3b of the first cam slide 3 is provided with a cutting blade or the like, a tool 3c for pressing the panel work w in cooperation with the punch 1a, and a stripper 3f made of an elastic body, and a base end 3d thereof. Is formed with a cam driver receiving surface 3e. On the other hand, a portion of the upper die 2 corresponding to the cam driver receiving surface 3e is provided with a first cam driver 4 having an inclined surface 4a.

Therefore, as the upper die 2 descends, the inclined surface 4a of the first cam driver 4 and the cam driver upper surface 3e of the first cam slide 3 come into contact with each other, and the first cam slide 3 is driven forward in a direction approaching the punch 1a, While the panel work w is pressed and held by the punch 1a by the stripper 3f provided at the front end 3b of the first cam slide 3, the panel work w is pressed by the tool 3c. Next, as the upper die 2 moves up, the spring causes the first cam slide 3 to retreat in a direction away from the punch 1a. At this time, the stripper 3f presses and holds the panel work w from the tool 3c for a while to separate it.

On the other hand, at a position where the upper die 2 approaches the first cam driver 3 when reaching the bottom dead center, the second cam slide 5 is provided with sliding pieces 5d, 5d protruding from both sides of the second cam slide 5, provided on the upper die 2. Part 2a (second
It is provided so as to be slidable in the contacting / separating direction B with respect to the punch 1a by being guided by (only shown in the drawing). Second cam slide 5
A tool 5b such as a cutting blade and a stripper (not shown) are provided at a front end portion 5a of the cam, and two cams facing each other with a distance allowing the movement of the first cam slide 3 at the base end portion. Driver receiving surfaces 5c, 5c are provided. Cam driver receiving surface 5
c and 5c have inclination angles different from the inclination angles of the cam driver receiving surface 3e of the first cam slide 3 and the inclined surface 4a of the first cam driver 4 according to the press working position of the panel work w.

On the other hand, at a position corresponding to the cam driver receiving surfaces 5c, 5c formed on the second cam slide 5 of the lower mold 1, a pair of cam driver bearing portions 1c which allow the first cam slide 3 to reciprocate and face each other, 1c are arranged side by side, and second cam drivers 6 and 6 having inclined surfaces 6a and 6a are provided on the tops of the driver support portions 1c and 1c. Therefore, as the upper die 2 descends, the inclined surfaces 6a, 6a of the second cam driver 6 come into contact with the cam driver receiving surfaces 5c, 5c of the second cam slide 5, and the second cam slide 5 advances toward the punch 1a. By driving, the panel work w is pressed and fixed to the punch 1a by a stripper (not shown), and then the panel work w is pressed down by the tool 5b provided on the punch 1a and the second cam slide 5. Next, the upper die 2 moves the second cam driver 5 away from the punch 1a and retreats, and the stripper removes the panel work w from the tool and returns to the top dead center position.

In the above embodiment, the second cam drivers 6 provided on the lower die 1 are arranged on both sides of the first cam slide 3 so as to face each other, and are formed on the second cam slide 5 slidably supported by the upper die 2. Although the configuration in which the cam driver receiving surfaces 5c, 5c are divided has been described, the first cam driver 4 and the cam driver receiving surface 3e of the first cam slide 3 provided on the upper die 2 are divided so as to sandwich the second cam slide 5. It is also possible to integrally configure the inclined surface 6a of the second cam driver 6 and the cam driver receiving surface 5c of the second cam slide 5 that are divided into two parts.
