The utility model increases the amount of grinding of the punching head, prolongs the service life of a punching head and retains the overall size and the performance of an upper die in the situation of shortage of length with long time grinding, and the upper die head is convenient to install and adjust.
Description
Technical field
The utility model relates to punch press punch die upper mould device, particularly numerical control press punch die upper mould device.
Background technology
The drift upper end of the punch die upper mould device of existing punch press is fixed on the nose of punch by screw thread, the lower end of drift is sleeved in stop ring and the guide pin bushing, be set with ejector spring between the nose of punch on the drift and the stop ring, the top and bottom of ejector spring are pressed over the lower surface of the nose of punch and the upper surface of stop ring respectively.When the drift cutting edge behind the contraction in length, needs to adjust the axial displacement of drift through grinding, to guarantee the axial height size of drift.Because drift moves down, stop ring is corresponding also to move down, and causes the ejector spring axial dimension to increase, and elastic force changes.And the change of patrix total height is big, causes the stamping-out performance change.Excessive for avoiding the patrix total height to change, the amount of grinding of drift cutting edge can not be greater than 2mm, and drift is limited service life.And patrix is installed, adjusts loaded down with trivial details.
Summary of the invention
The utility model purpose provides a kind of numerical control press upper punch die head composite set, this device is after drift grinds, under the situation that punch length shortens, after adjusting, can keep the precompressed length of ejector spring and patrix overall size constant, thereby make the blanking performance of mould constant all the time, the service life of improving drift simultaneously.
Technical solution of the present utility model is to be provided with the ejector spring stopping means between the nose of punch of numerical control press upper punch die head composite set and the guide pin bushing.
Above-described ejector spring stopping means can be made up of sleeve, ejector spring, adjusting head, stop ring, snap ring, the upper end of sleeve endoporus is provided with inner convex platform, its lower end is provided with interior annular groove, regulate the lower end of head and the upper end of stop ring and be respectively equipped with protruding circle, regulate the top and bottom that head and stop ring are located at sleeve respectively, ejector spring is located to be regulated between head and the stop ring, and snap ring is located between the interior annular groove of the lower end of the protruding circle of stop ring and sleeve lower end.
Ejector spring stopping means of the present utility model can be made up of sleeve, ejector spring, adjusting head, stop ring, the upper end of sleeve endoporus is provided with inner convex platform, its lower end is provided with shrinkage pool, regulate the lower end of head and the upper end of stop ring and be respectively equipped with protruding circle, regulate the top and bottom that head and stop ring are located at sleeve respectively, ejector spring is located to be regulated between head and the stop ring.
The adjusting head of ejector spring stopping means of the present utility model can be connected with the external screw thread of drift by internal thread, regulates between the head and the nose of punch and can be provided with clamping screw.
The nose of punch of the present utility model can be connected with the shrinkage pool of regulating the head upper end by the boss of its lower end, can be provided with zero shape circle between the composition surface.
The nose of punch of the present utility model also can be connected with the boss of regulating the head upper end by the shrinkage pool of its lower end, can be provided with zero shape circle between the composition surface.
Principle of the present utility model is: after the drift cutting edge grinds because of wearing and tearing, its contraction in length, unclamp the nose of punch and the set bolt of regulating head during adjustment, the rotation drift is to regulate the patrix height, this moment, zero type circle was in course of adjustment the height of patrix to remain unchanged, and the bolt that is tightened is promptly adjusted end.Because it is highly constant to adjust the precompressed of back ejector spring, the overall size of patrix is constant, thereby makes the stamping-out performance of patrix constant all the time.The amount of grinding of drift cutting edge obtains increasing, thereby has prolonged the service life of drift.
The utility model has the advantages that: grind under the situation of its contraction in length of back in the drift wearing and tearing, after adjusting, the overall dimension of patrix remains unchanged, thereby makes the stamping-out performance of patrix constant all the time; The amount of grinding of drift cutting edge obtains increasing, and is increased to 5mm by 2mm, has prolonged the service life of drift; Installation, easy to adjust, quick.
