Description of the invention (1) [Technical field of the invention] The present invention relates to a rotary drive device for a rotary body, for example, a rotary cam drive device for a negative-angle forming mold for forming a metal sheet with K . Here, the so-called negative-angle forming die refers to the concave forming in which the downward trajectory of the upper die enters the lower die. The negative-angle forming of the sheet metal workpiece into the lower die by the downward trajectory in the straight direction of the upper die is generally performed using a sliding cam. The concave forming of the metal sheet from K is to place the workpiece on the lower die, and the upper die is lowered vertically downward. The driven cam of the lower die is driven by the upper cam's action cam plus K, and is moved from the horizontal direction. When the workpiece is machined and the upper die is raised after the machining, the action cam is retracted by a spring. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs (please read the notes on the back to write this page). In this case, the forming part of the driven cam that slides from the outside of the workpiece in the lateral direction to form the workpiece is The forming part of the workpiece has the same shape, but the forming part of the lower mold with the workpiece must be removed from the lower mold after processing. Therefore, the concave part of the lower mold must be divided so that it is retracted or cut off first. The rear part of the recessed part moves the workpiece forward. The workpiece can be taken out. If the degree of recession is small, it will not cause a problem, but when the degree of recession is large or the shape of the workpiece is slender and frame-shaped, such as the parts of the front pillar other than the metal sheet of the car, the The groove width is narrow. When the concave lower mold part is to be divided or cut off, not only cannot the obvious configuration be formed in the forming part of the driven cam, but the strength of the lower mold is also insufficient, and the concave forming process cannot be performed. In addition, the product may be distorted or deformed, and the situation of the product must be corrected, but for example, the outer plate, fender, top plate, hood, luggage -4- This paper size applies to China National Standard (CNS) A4 specifications (210 X 297 mm) 583038 A7 B7 V. Description of the invention (2) Parts such as covers, door panels, and outer front pillars that use K to form the outer panel part of the car have a three-dimensional curved surface / curve. The modification of the product is almost impossible. possible. When assembling metal sheets for automobiles, it is difficult to combine them with other parts when the products are distorted or distorted. It cannot provide a high-quality metal sheet structure for automobiles, and cannot maintain the precision of a predetermined product of a metal sheet molded product. • In order to solve the above problem, there has been a proposal of the lower structure, which uses the downward trajectory of the upper mold to make the forming part entering the lower mold into a κ shape. After forming, the rotary cam rotates backward, Until the formed workpiece can be taken out from the lower mold. That is, as shown in FIG. 11 to FIG. 16, the negative-angle forming mold is composed of: a sheet metal workpiece W is placed under the support portion 1Q1 撗 102, and the phase leader is in a straight direction on the aforementioned lower mold 102. The workpiece is lowered and punched, and the workpiece is formed by forming the upper die 103. And the lower die 102 is freely provided with an opening facing the outer peripheral surface, and has a groove 10 engraved in the axial direction. A recess is formed in the groove 10 4 near the edge of the support 101 and enters from the locus of the upper die. The rotating cam 106 of the forming part 105 is rotatably provided on the upper die 103, which has a concave forming part 107, and a sliding cam 108 opposite to the aforementioned rotating cam 106; M is provided in the lower die 102, and after forming The pressure cylinder 109 can be configured to rotate the revolving cam 106 back to the state where the workpiece W is taken out from the lower mold 102. When the work W placed on the support part 101 of the lower mold 102 slides, the work W is formed and formed by the concave forming part 105 of the rotary cam 106 and the concave forming part 107 of the slide cam 108 when the sliding cam 108 slides. Then, the rotary cam 106 is rotated backward by the pressure cylinder 109, and the formed workpiece W is taken out from the lower die 102. -5- This paper size applies to China National Standard (CNS) A4 (210 X 297 mm)
