[0018] Please see Figure 1-2 This utility model provides a technical solution: a composite forming device, including a die forming and positioning device and an upper die forming device. The die forming and positioning device includes a positioning block 7, a stripper plate 8, a spring 9, an inner forming punch 10, guide pillars 11, and a die base 13. Guide pillar holes are opened on both sides of the top of the die base 13. A die fixing plate 12 is installed in the middle of the top of the die base 13 by screws and pins. The inner forming punch 10 is installed in the middle of the top of the die fixing plate 12. Spring holes are opened at the four corners of the top of the die fixing plate 12. Springs 9 are installed in the spring holes. A stripper plate 8 is set on the top of the springs 9. A slot is opened in the center of the top of the stripper plate 8, and a positioning block 7 is installed in the slot by screws. Two guide pillars 11 are installed in the two guide pillar holes.
[0019] The upper die forming device includes an outer forming punch 2, an upper die fixing plate 3, an upper die base 4, a guide sleeve 5, and a die shank 6. The upper die base 4 has guide sleeve holes on both sides of its surface, and the two guide sleeve holes are engaged and slidably connected with the corresponding two guide posts 11. The die shank 6 is installed in the middle of the top of the upper die base 4 by screws. The upper die fixing plate 3 is installed in the center of the bottom of the upper die base 4 by screws and pins. The center of the bottom of the upper die fixing plate 3 has a center positioning groove, in which the outer forming punch 2 is installed.
[0020] Furthermore, the stripper plate 8 is fixedly connected to the die fixing plate 12 by four equal-height screws.
[0021] Furthermore, the surface of the guide post 11 is connected to the guide sleeve hole through the guide sleeve 5.
[0022] Furthermore, the bottom of the outer forming punch 2 coincides with the lower surface of the upper die base 4, and the outer forming punch 2 and the positioning block 7 are in a concentric position.
[0023] Furthermore, a workpiece 1 is installed between the positioning block 7 and the outer forming punch 2.
[0024] Working Principle: This device is an auxiliary shaping device for product manufacturing, used in conjunction with a pneumatic press, and powered by pneumatics. Place the composite shaping device on the pneumatic press's worktable, adjust its position so that the die handle 6 is engaged in the upper die sleeve of the press and secured with screws. Then, use pressure plates to press down on both sides of the die holder 13, completing the fixation of the composite shaping device. Press the pneumatic switch; the upper die shaping device moves upward to the press's working stroke origin position. At this point, both parts of the composite shaping device are in the open state. After placing the workpiece 1 on the upper part of the positioning block 7, press the pneumatic switch again. The upper die shaping device moves downward. After moving a certain distance, the bottom of the outer shaping punch 2 contacts the upper surface of the workpiece 1 first, causing the workpiece 1 to press down simultaneously. During the downward pressing process, the positioning block 7, under pressure, drives the stripper plate 8 downward, and the spring 9 contracts under force. The device stops operating when the bottom plane of the positioning block 7 coincides with the upper plane of the middle part of the inner shaping punch 10. At this point, the outer forming punch 2, the positioning block 7, and the inner forming punch 10 form a hollow cavity corresponding to the key position of workpiece 1, which compresses and corrects workpiece 1, thus completing the shaping of workpiece 1. Clicking the pneumatic switch again retracts the upper die forming device to its highest point. Simultaneously, the spring 9 rebounds, causing the positioning block 7 to lift workpiece 1 upwards, disengaging it from the inner forming punch 10, and then workpiece 1 is removed. This completes one full operation.
[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
