Description
Technical field
The utility model relates to the punch press die set, particularly the Capstan Head of Numerical Control Press die set.
Background technology
Existing Capstan Head of Numerical Control Press punch die upper mould device great majority are connected stop bit with the attacking head sub-assembly with the guide pin bushing sub-assembly with the O RunddichtringO, and after the O RunddichtringO damaged, the attacking head combination might get loose in the guide pin bushing sub-assembly.Some Capstan Head of Numerical Control Press punch die upper mould device is without O RunddichtringO stop bit, but also has only single binding stop bit.
Summary of the invention
The purpose of this utility model provides a kind of Capstan Head of Numerical Control Press punch die patrix composite set, utilizes the dual stop bit that is connected of attacking head sub-assembly and guide pin bushing sub-assembly, improves the flexibility of stability, reliability and operation.
Technical solution of the present utility model is that the guide pin bushing sub-assembly of Capstan Head of Numerical Control Press punch die patrix composite set is provided with a lock ring, the outside on the top that is sleeved on guide pin bushing of lock ring activity; The endoporus limit on the top of lock ring is provided with a tapering chamfering; Lock ring top is provided with at least two shotpins; The position corresponding with shotpin, guide pin bushing top respectively is provided with an elongated slot vertically; The guide pin bushing upper surface is provided with a plurality of holes, is provided with stage clip in the hole; Guide pin bushing top is provided with the circular hole that at least 4 the inners have taper hole, is respectively equipped with steel ball in circular hole; On the external cylindrical surface of described stop ring middle part with guide pin bushing on the position of steel ball be arranged with a plurality of closed pockets along circumferentially waiting, in the endoporus that is contained in guide pin bushing top of stop ring activity.
The nose of punch in the above-described attacking head sub-assembly can be connected with the punch die guide rod by 2 half sheet back-up rings.
The punch die guide rod of getting a sub-assembly of the present utility model can be by its lower end external screw thread with towards the internal thread on core top be connected towards core.
Stripper of the present utility model can be fixed on the protruding position of guide pin bushing bottom by its inner groovy, and the opening of guide pin bushing is provided with positioning ball.
Operation principle of the present utility model is: Capstan Head of Numerical Control Press punch die patrix composite set of the present utility model is packed in the cylinder sleeve of capstan head on the NCT punch press, prop up guide pin bushing on the upper stage terrace with spring.At first with power the nose of punch is moved down, drive whole patrix and press down, when the bottom stripper compressed plate to be punched, power continued to press down the nose of punch.At this moment material returned spring is compressed, and the nose of punch presses down the punch die guide rod by two back-up rings, thereby the core that dashes that is connected on the punch die guide rod is pressed down, until finishing the punching press action.Punching press power is removed during backhaul, and compressed material returned spring releases energy, and internal force makes the punch die guide rod together with withdrawing from from the plate that is stamped by stripper towards core.Meanwhile, the spring of the pressure guide pin bushing on the capstan head also releases energy, and a whole set of patrix is resetted.The unitary closed height of this device is determined by design, need not to adjust.But towards the core cutting edge in use can passivation sharpening again.What need renew after it damages dashes core, must readjust the position towards core, makes its cutting edge and a stripper outer face maintenance suitable distance (generally being 0.5-1.5mm).
The utility model has the advantages that: the attacking head sub-assembly is the dual stop bit that is connected with the guide pin bushing sub-assembly, and when the O RunddichtringO lost efficacy, the attacking head sub-assembly can not get loose in the guide pin bushing sub-assembly yet, has increased the reliability of mechanism, stability and flexibility; But towards the fine setting of core length small distance, the minimum stroke of the each fine setting of its cutting edge length is 0.067mm, helps the accurate fine setting of mould shut height; Attacking head sub-assembly and guide pin bushing sub-assembly are normally closed latch mechanism, have only lock ring is applied downward pressing force, just can make mechanism's release, and make connection and combine closely towards the two function of core length adjustment, and the two carries out simultaneously; Each parts is stressed rationally, and the life-span is long, and except that sharpening or change towards core, package unit can use for a long time, need not maintenance or replacing.
