Abstract
The utility model relates to an upper die device for the punching die of punch turret, belonging to the punch and punching die device, which is characterized in that one to four locating pins are distributed evenly on the lower end face of the snap ring of the strike head assembly; six to twelve locating holes which are integral multiples than the quantity of the locating pins are distributed evenly on the circumference part of the upper end face of the guide sleeve corresponding to the locating pins. With the selective matching of the locating pins on the lower end face of the snap ring and the locating holes on the upper end face of the guide sleeve, while the punch cutting edge is grinded and shortened and needs to adjust the axial movement of the punch, the utility model enables to adjust the length of the punch quickly, and has the advantages of reliable location and simple structure.
Description
Technical field
The utility model relates to the punch press die set, particularly the upper mould device of capstan head punch die.
Background technology
The drift upper end of the capstan head 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 respectively on the upper surface of the lower surface of the nose of punch and stop ring.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 blanking performance change.Though between the nose of punch and guide pin bushing, set up the ejector spring stopping means, 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 of mould constant all the time, the service life of improving drift simultaneously.But its weak point is the punch die structure more complicated, and adjusts loaded down with trivial details.
Summary of the invention
The purpose of this utility model provides a kind of punch press capstan head punch die upper mould device, this device is after drift grinds, under the situation that punch length shortens, can adjust the axial displacement of drift apace, after adjusting, can keep the blanking performance of mould constant, improve the service life of drift, and simple in structure.
Technical solution of the present utility model is to be laid with one to four alignment pin on the lower surface of stop ring of attacking head sub-assembly of punch press capstan head punch die upper mould device, is laid with six to 12 locating holes that become integral multiple with the alignment pin respective numbers on the upper surface of guide pin bushing with on the corresponding circumferential location of described alignment pin.
Above-described attacking head sub-assembly can be provided with hollow guide rod, and the upper end of drift is fixed on by being threaded in the hollow guide rod endoporus.
The mobilizable lower end that is fixed on the hollow guide rod outside of the stop ring of above-described attacking head sub-assembly, the lower end edge of hollow guide rod is axially arranged with gathering sill, radially is provided with guide finger on the stop ring with on the corresponding position of described gathering sill.
Drift of the present utility model can by guide rod with form towards core, lower end of the guide rod by screw thread be connected on the core.
Operation principle of the present utility model is, when drift cutting edge and behind the contraction in length through grinding, only need the stop ring of attacking head sub-assembly is up drawn, the alignment pin that is fixed on the stop ring lower surface is pulled out from the locating hole of guide pin bushing upper surface, stop ring is rotated to an angle with respect to the guide pin bushing inhour, then the alignment pin on the stop ring lower surface is aimed at locating hole corresponding on the guide pin bushing upper surface and be pressed into, the stop ring lower surface is pressed on the upper surface of guide pin bushing, thereby adjusts the axial displacement of drift.
The utility model has the advantages that the axial displacement of adjusting drift is quick, the location is reliable, and simple in structure, and low cost of manufacture can prolong drift service life more than 2 times than existing upper mould device.
