Definitions

  • the present invention relates to a punch assembly, and more specifically to a punch assembly of CNC punch press machine.
  • the punch assembly of CNC punch press machine of the Chinese Patent No. ZL200520065714.7 has advantages, such as reliable connection between the guide assembly and the punch head assembly, fine-adjustment of the length of the plunger, and long operating life of the mechanism.
  • it needs to pinch the locking ring by hand during adjustment to bring the guide sleeve and the locking ring into adjustment state, and the operator has to operate with the other hand.
  • it is inconvenient, and the popularization of this type of product is affected in a certain extent.
  • the object of the present invention is to provide a punch assembly of CNC punch press machine, with which a mechanism for maintaining adjustment state is provided while all kinds of adjustment functions of the Chinese patent No. ZL200520065714.7 are maintained, and the adjustment is made easier.
  • a punch assembly of CNC punch press machine includes:
  • a guide assembly includes:
  • a locking ring movably sleeved outside an upper part of the guide sleeve, wherein two symmetric circular grooves are provided on the locking ring;
  • a press type of lock system is provided between the guide sleeve and the locking ring
  • the press type of lock system comprises a hook pin and a spring
  • the hook pin is provided with a latch hook
  • the guide sleeve is provided with a cylinder hole
  • the cylinder hole is configured to cooperate with the hook pin in a manner of sliding fit
  • the spring is set in the cylinder hole
  • a flat groove is provided on a lower end surface of the locking ring, which allow the hook pin slide rather than rotate, and a groove is provided on an inner end face of the flat groove matching the latch hook of the hook pin.
  • the forepart of the hook pin may be flat circular, the lower part of the hook is provided with a serrated latch hook, and the tail part of the hook is cylinder shaped.
  • the working principle of the present invention is: when the protruding length of the plunger chip need to be adjusted, the locking ring is turned clockwise, and the flat groove of the locking ring slides along the hook pin with a flat circular shaped head.
  • the serrated latch hook falls into the groove under the push force from the tail spring, which makes the locking ring unable to rotate, and the entire mechanism is in a state of adjustment.
  • the serrated latch hook is released from the groove and slides into the hole of the guide sleeve, and the locking ring is rotated counterclockwise under the push force from the two restoring springs until being stopped at working position by the shotpin, and the mechanism is in the working state.
  • FIG. 1 is a construction schematic diagram of one embodiment of the present invention.
  • FIG. 2 is a sectional diagram along A-A line of FIG. 1 in working state.
  • FIG. 3 is a sectional diagram along A-A line of FIG. 1 in working state.
  • FIG. 4 is a sectional diagram along B-B line of FIG. 1 in working state.
  • FIG. 5 is a sectional diagram along B-B line of FIG. 1 in adjustment state.
  • FIG. 6 is a stereogram of the hook pin according to one embodiment of the present invention.
  • FIG. 7 is a stereogram of the locking ring (bottom up) according to one embodiment of the present invention.
  • the punch assembly of CNC punch press machine of the present invention includes a punch head assembly 24 , a guide assembly 25 , a punch 11 and a stripper plate 13 .

  • the locking ring 17 is mounted with two poke pins 14 , one end of which is fixed on the locking ring 17 , and the other end of which is inserted into one end of the pressure spring 16 in the circular groove 21 on the guide sleeve 9 .
  • the locking ring 17 turns a degree relative to the guide sleeve 9 within the range limited both by the locking ring 17 and the circular groove 21 .
  • two pressure springs 16 push two poke sheaths 14 of the locking ring 17 , and then drive the locking ring 17 rotate to return to its original position.
  • the guide sleeve 9 is provided with four holes with cone holes inside, which are set with four small steel balls 18 respectively.
  • the small steel ball 18 falls into the seal groove 23 of the outside surface of the container ring 7 in the punch head assembly 24 , and the outside surface of the container ring 7 is locked by the locking ring 17 , thus the punch head assembly 24 can be locked.
  • the punch head assembly 24 can rotate, and can be pulled out from the guide assembly 25 .
  • the punch 11 is provided with a dowel pin 10 .
