  • a swing cam scheme 20 in which a swing cam 21 corresponding to the cam slide 6 is rotatably swung in one direction about a support point (swing axis 22) of a cam axis eccentrically located from a center as shown in FIG. 1b as a length of an actuating cylinder 23 is varied, in order to separate the bent panel P from a die after performing the relief forming work of bending the end of the panel P according to a punching work of the cam slide 6 in the cam housing 8 of the cam base 7.
  • the foreign matters do not adhere to the rotary cam 11 or the cam operating groove 8b inside the cam housing 8 even if the foreign matters are introduced into the space between the rotary cam 11 and the cam operating groove 8b inside the cam housing 8. Accordingly, it is unnecessary to disassemble the whole relief forming apparatus in order to repair the swing cam 21 or replace parts with new one, so that the maintenance work for the relief forming apparatus employing the swing cam scheme 20 is easy and simple.
  • the swing cam 21 closely makes contact with the cam housing 8a when the relief forming work of bending the end of the panel P according to the punching work of the cam slide 6 is performed, so that a pushing phenomenon is less represented differently from the rotary cam scheme 10. Accordingly, the quality for the relief forming work of the panel P can be improved.
  • the swing cam 21 is rotatably swung at a predetermined angle about the swing axis 22 inserted into the swing cam 21 serving as a rotation point due to the actuating cylinder 23, the rotational angle of the swing cam 21 is smaller than that of the rotary cam scheme 10, so that the amount of the rotation of the swing axis 22 is reduced.
  • the center of the swing axis 22 and the parting of the cam housing 8a for the swing cam 21 are freely selected.
  • the operating structure and the operating mechanism in the swing cam scheme 20 are significantly complex and difficult as compared with the rotary cam scheme 10.
  • the actuating cylinder 23 is moved back and forth, noise is caused, and the torsion of the swing cam 21 according to the return operation of the swing cam 21 is applied to the swing axis 22, so that the rebound phenomenon occurs.
  • a cam driver (not shown) of a lower mold provided in the relief forming part is involved to cause unnecessary resistance.
  • the present invention is made while keeping in mind the above problems occurring in the related art, and the object of the present invention is to provide a relief forming apparatus in which an end of a primarily molded panel fixed through cooperation among a panel supporting pad vertically moved down through a press operation, and a relief die block and a main die block is bent by a cam slide pressed by a cam slide supporting base moved down to slidably move to the relief die block along a slide face of a cam driver, thereby performing a relief forming work, and then, when the panel supporting pad and the cam slide are returned to original positions, a die fixing block, which is coupled with an upper end of a spring and fixedly supports a lower end of the main die block, is mutually slidably coupled with a slide block coupled with a lower end of the spring fixedly installed with a lower end of the relief die block, and relief die driving blocks are installed at the lower end of the slide block to support the relief die block and the slide block and to control a lifting operation of the slide block according to variation in a
  • Another object of the present invention is to reduce machining cost and manufacturing cost, simplify a modification process and maintenance, and maximize the utilization of a space in a mold as a simpler structure is employed, when comparing with a rotary cam scheme of rotating a rotary cam corresponding to a cam slide in one direction in order to separate a bent panel from a die block after performing a relief forming work of bending the end of the panel according to a punching work of a cam slide in a cam housing of a cam base among conventional relief forming cam schemes, because a slide block and a relief die block according to the present invention have slide structures in which the slide block and the relief die block are linearly moved from the main die block and the die fixing block in such a manner that the slide block and the relief die block are inclined downward, due to the release of the locking of the relief die driving block according to the extension in the length of the air cylinder and the elastic force of the spring.

  • the slide block and the relief die block have slide structures in which the slide block and the relief die block are linearly moved from the main die block and the die fixing block in such a manner that the slide block and the relief die block are inclined downward, due to the release of the locking of the relief die driving block according to the extension in the length of the air cylinder and the elastic force of the spring, as the structure is simpler, when comparing with the rotary cam scheme of rotating the rotary cam corresponding to the cam slide in one direction in order to separate the bent panel from the die after performing a relief forming work of bending the end of the panel according to the punching work of the cam slide in the cam housing of the cam base among conventional relief forming cam schemes, thereby reducing machining cost and manufacturing cost, simplifying a modification process and maintenance, and maximizing the utilization of a space in a mold
