Abstract

The utility model discloses an accurate carbide drift, include towards needle cover with towards the needle device, include firstly towards needle and second towards needle towards the needle device, firstly be equipped with first screw thread towards needle both ends, its both ends are connected in round punch and square drift, the second is equipped with a thread groove towards needle one end, is equipped with the second screw on its other end, and is connected with the triangle drift, it is equipped with the 2nd thread groove to put in towards the needle, the utility model discloses a what be equipped with is first towards needle and second towards needle, first be equipped with respectively on towards needle and second towards the needle square towards needle, circular towards needle and triangle towards needle, can be through arbitrary connections between screw and a thread groove, the 2nd thread groove during use, the different shapes of realization change dash the needle, consequently the utility model discloses can change the needle that dashes of different shapes as required to satisfy different requirements of the processing, just so can be in the same place the needle collection dress that dashes of multiple shape, practiced thrift raw materials for production greatly, easily carry moreover.

Description

A kind of accurate hard alloy punch head

Technical field

This utility model relates to a kind of drift, is specially a kind of accurate hard alloy punch head.

Background technology

Requisite accessory when that red needle being diel work, belongs to removable mould consumptive material, is mounted in Carry out continuous stamping punching press in diel and thrust operation, make machined material occur to separate or plastic deformation, thus obtain institute The finished product needed or semi-finished product, traditional drift is the most all a shape, during if it is desired to use other shape drift, needs Separately to do one, so will result in the waste of material, but also be to separate to carry, be easily lost, therefore for problem above It is the most necessary for designing a kind of accurate hard alloy punch head.

Utility model content

For problem above, this utility model provides a kind of accurate hard alloy punch head, and this utility model can basis Need to change difform red needle, to meet different processing needs, thus the red needle collection of various shape can be contained in Together, being greatly saved raw materials for production, and be easy to carry about with one, terminal with compact integral structure is practical, simple to operate, and it is convenient to change, cost Cost is relatively low, has the most wide market prospect, can effectively solve the problem in background technology.

For achieving the above object, this utility model following technical scheme of offer: a kind of accurate hard alloy punch head, including punching Needle guard and red needle device, described red needle device includes the first red needle and the second red needle, and described first red needle two ends are provided with the first spiral shell Stricture of vagina, its two ends are connected to round punch and square drift, and described second red needle one end is provided with the first thread groove, on its other end It is provided with the second screw thread, and connects and have triangle drift, described red needle to put to be provided with the second thread groove.

It is provided with scale in this utility model a kind of preferably technical scheme, described first red needle and the second red needle, Unit is in terms of mm.

Compared with prior art, the beneficial effects of the utility model are: this utility model by the first red needle of being provided with It is respectively equipped with square red needle, circular red needle and triangle red needle in second red needle, the first red needle and the second red needle, can lead to during use Cross and arbitrarily connect between screw thread and the first thread groove, the second thread groove, it is achieved change difform red needle, therefore this reality Difform red needle can be changed as required with novel, to meet different processing needs, thus can be by multiple shape The red needle collection of shape is fitted together, and is greatly saved raw materials for production, and is easy to carry about with one, and terminal with compact integral structure is practical, simple to operate, It is convenient to change, and cost is relatively low, has the most wide market prospect.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The every other embodiment obtained, broadly falls into the scope of this utility model protection.

Embodiment:

Referring to Fig. 1, Fig. 2, Fig. 3 and Fig. 4, this utility model provides a kind of technical scheme: a kind of accurate hard alloy rushes Head, including red needle set 1 and red needle device 2, described red needle device 2 includes the first red needle 3 and the second red needle 4, described first red needle 3 Two ends are provided with the first screw thread 5, and its two ends are connected to round punch 6 and square drift 7, and described second red needle 4 one end is provided with first Thread groove 8, its other end is provided with the second screw thread 9, and connection has triangle drift 10, described red needle set 1 to be provided with the second spiral shell Stricture of vagina groove 11；Being provided with scale 12 in described first red needle 3 and the second red needle 4, unit, in terms of mm, is used for measuring punching press length.

This utility model is by the first red needle being provided with and the second red needle, the side of being respectively equipped with in the first red needle and the second red needle Shape red needle, circular red needle and triangle red needle, can be by appointing between screw thread and the first thread groove, the second thread groove during use Meaning connects, it is achieved changing difform red needle, therefore this utility model can change difform red needle as required, with Meet different processing needs, thus the red needle collection of various shape can be fitted together, be greatly saved raw materials for production, and And be easy to carry about with one, terminal with compact integral structure is practical, simple to operate, and it is convenient to change, and cost is relatively low, has the most wide market Prospect.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model Protection domain within.
