Definitions

  • the present invention relates to a press device.
  • a press device generally performs presswork such as boring or molding by respectively attaching a lower die to a bed and an upper die to a ram of a press machine wherein the upper die performs rising/descending movements. Processing in lateral directions is performed by transforming, by the use of a cam member, the processing force in vertical directions that is provided by the upper die rising and descending in vertical directions.
  • a positioning member 104 is provided as to be extruding from a lower die 101 for positioning a work W.
  • a passive cam 107 comprising a punch 106 is provided in a slidable manner at a position at which it opposes a punching hole 105 on a side wall of the work W.
  • a heel 108 is fixedly attached in a rear portion of the passive cam 107.
  • a coil spring 109 is screwed to the passive cam 107 and is outwardly fitted to a tip portion side of a rod 110 that is piercing through the heel 108, while one end of the coil spring 109 is abutted against the heel 108, and to the other end of the coil spring 109, a nut 112 is screwed with a washer 111 provided intermediately.
  • An operating cam 118 is provided in an extruding manner at an upper die 116 at a position at which it opposes the passive cam 107.
  • the operating cam 118 forces the passive cam 107 to move forward against the energizing force of the coil spring 109 whereby the hole 105 is formed on the work W through the punch 106 and a die 125, and when the upper die 116 is lifted, the passive cam 107 is retracted by the energizing force of the coil spring 109.
  • the passive cam 107 provided with the punch 106 performs approaching and receding movements with respect to the work W so as to perform sliding movements above the lower die 101.
  • the sliding movements of the passive cam 107 need to be accurate since boring is performed by the punch 106 and the die 125, and for this reason, a flanges 121 are provided in an extruding manner from both sides of a lower portion of the passive cam 107, and a lateral guide plate 122 and upper guide plate 123 for guiding the flanges 121 are fixed to the lower guide 101.
  • the lateral guide plates 122 are arranged for guiding a side surface of the flanges 121 extruding from both side of a main body of the passive cam 107a, and the upper guide plates 123 for guiding an upper surface of the flanges 121, for making the passive cam 107 perform repetitive, sliding movements between specified positions.
  • the flanges 121, lateral guide plates 122 and upper guide plates 123 there are formed, on both lateral sides of the main body portion 107a of the passive cam 107, extruding portions by length L, respectively, wherein the length L is usually in a range between 100 to 150 mm at minimum so that the whole arrangement requires a large space above the lower die 101 of the press device.
  • a cam mechanism will occupy a large space within a press device. Due to the large space that is required for the provision of such a cam mechanism, it may be that some required members may not be able to be included in the press device since the size of the whole press device is restricted by a bed area of the press machine. Consequently, it may happen that additional press devices need to be provided to perform additional steps for the processing.
  • a wear plate 124 that is provided at a tip of the flange 121 extruding laterally from the main body portion 107a of the passive cam 107 is gradually worn by the repetitive sliding movements of the passive cam 107 so that a clearance may be created between the wear plate 124 and the lateral guide plate 122.
  • the passive cam 107 may not be able to slide in a linear manner and may meander owing to the existence of the clearance.
  • the punch 106 attached to the passive cam 107 will simultaneously meander, the punch 106 may not be able to perform punching in a preferable condition in which an appropriate clearance is formed over the whole circumference with respect to the die 125 so that burrs are formed along the circumference of the punched hole and boring processes of high quality could not be achieved. Additionally, since the punch 106 and die 125 performed punching causing burrs, there were also caused chipping of cutting edges of the punch 106 or the die 125.
  • This press device is comprised of a sliding cam base 213 provided at an upper die 211 and which tip portion is provided with a tetrahedron guide portion 216, a sliding cam 217 which embraces the tetrahedron guide portion 216 of the sliding cam base 213, which makes the tetrahedron guide portion 216 slide, and to which processing members such as punch 243 or trimming cutting edge 251 are attached, an elastic member 264 interposed between the sliding cam base 213 and the sliding cam 217 for energizing the sliding cam 217, an operating cam abutting against the sliding cam 217 and provided at a lower die 202 for driving the sliding cam 217, and a positioning member 204 provided on the upper die 211 for supporting a work W for which presswork is to be performed using the processing members.
  • the sliding cam 217 moves in a lateral direction between the operating cam 208 and the sliding cam base 213 for performing presswork such as boring or trimming.
  • the sliding cam 217 is returned, being energized by the elastic member 264.
  • an upper end of the sliding cam 217 is formed on a same inclined plane as the tetrahedron guide portion 216 of the sliding cam base 213 and is further formed with a groove for receiving the tetrahedron guide portion 216, a wear plate 223 is fixed by means of a bolt 224 for supporting a lower plane 225 of the tetrahedron guide portion 216 of the sliding cam base 213, an upper plane 226 thereof being pressed by a tapping plate 228 attached to the sliding cam 217 by means of a bolt 227, and the sliding cam 217 is provided in a freely slidable manner at the tetrahedron guide portion 216 of the sliding cam base 213.
  • a returning plate 271 is fixedly attached to the sliding cam 217 by means of a bolt 272, while a lower end thereof is engaged to the operating cam 8.
  • the sliding cam to which processing members such as the punch 243 or trimming cutting edge 251 are attached be also applicable for receiving various components such as springs thereat.
  • a press device free of warps or rolling and capable of performing accurate processing, comprising a sliding cam base, a sliding cam that is guided by the sliding cam base and to which processing members such as a punch are attached, an energizing body provided between the sliding cam base and the sliding cam for energizing the sliding cam, and an operating cam abutted against the sliding cam for driving the sliding cam, wherein the press device is arranged in that the sliding cam is provided in a freely slidable manner between two guide posts of circular section suspended from the sliding cam base and separated from each other by a specified distance, and wherein one surface of the sliding cam base is formed as a V-shaped groove and a surface of the sliding cam opposing this surface of the sliding cam base is formed, at the operating cam thereof, with an angular guide portion abutting the V-shape groove.
