Abstract
The utility model discloses a take out hole special use towards needle, including needle body and syringe needle, the syringe needle sets up the bottom of needle body the bottom of syringe needle has the four pyramid cutting edge that is used for tearing the work piece, the shape of four pyramid cutting edge is the coincide body of rectangular pyramid and cylinder, wherein cylindrical portion with needle body fixed connection, the needle body comprises canned paragraph and intensive section, the canned paragraph with it connects to reinforce the top of section, the bottom of reinforceing the section with the syringe needle is connected. It is showing the effect: that treats processing takes out hole one shot forming, has improved production efficiency, the high height of taking out in hole is easily riveted, and the yield is high, and pore wall and rationally less towards the friction of needle, towards the difficult rupture of needle, prolonged towards the life of needle.
Description
Technical field
The utility model relates to hardware dies and takes out hole technical field, specifically, is that one takes out the special red needle in hole.
Background technology
Red needle has another name called drift punch, and in general industry activity, a lot of punching press grinding tool product needed process the flanging bore with certain size and requirement of strength in its wall pieces, and this flanging bore is generally used as connecting the bottom outlet of screw thread.Existing hardware stamping industry often has punching to carry out the technique riveted, and first rushes an aperture, takes out hole the most again.Red needle is little easy broken needle, machined extraction the most inadequate.And the red needle of routine includes shank and syringe needle, syringe needle is cylinder, is planar structure bottom it, utilizes this red needle to be processed producing substantial amounts of waste material, need to carry out regularly hand sweeping；Additionally there are the easy strip of rapid wear, intensity is too low and destroys aperture, and the yield rate thereby resulting in punching is relatively low, it is impossible to meet the needs of actual production.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide one and takes out the special red needle in hole, and rectangular pyramid structure is processed in this red needle front end, workpiece after tear becomes four shapes of blooming, the highest easy riveting, and red needle is the most easily broken, service life is long, it is possible to increase production efficiency.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is as follows:
One takes out the special red needle in hole, including needle body and syringe needle, it it is critical only that: described syringe needle is arranged on the bottom of described needle body, there is the rectangular pyramid shape blade for tearing workpiece in the bottom of described syringe needle, described rectangular pyramid shape blade be shaped as rectangular pyramid and cylindrical overlapping body, wherein cylindrical portion is fixed with described needle body and is connected.
This red needle is in use, owing to the top syringe needle of red needle is rectangular pyramid shape blade, can tear workpiece when punching, the workpiece after tear becomes four shapes of blooming, and scatter from inside to outside, to be processed take out hole can one-shot forming, improve production efficiency, the high easily riveting of hole height of extraction, yield rate is high, and hole wall is the least with the friction of red needle, red needle is not easily broken, and extends the service life of red needle.
Further, in order to ensure the structural strength of red needle so that it is not easy fracture, described needle body is made up of canned paragraph and strengthening segment, and described canned paragraph is connected with the top of described strengthening segment, and the bottom of described strengthening segment is connected with described syringe needle.
Further, the rectangular pyramid part of described rectangular pyramid shape blade is positive rectangular pyramid.
Pass through said structure, it is possible to make four face uniform force of red needle top pyramid body, thus reduce the infringement probability of red needle, contribute to extending the service life of red needle.
Further, the angle of place plane is installed in four faces of described rectangular pyramid shape blade with it is 30 °～120 °.
Further, the diameter of described needle body is more than the diameter of described syringe needle.
Further, in order to ensure the structural strength of this red needle, described needle body is one-body molded with syringe needle, and all uses ferrous materials to make.
Remarkable result of the present utility model is: to be processed takes out hole one-shot forming, improves production efficiency；The high easily riveting of hole height extracted out, yield rate is high；And hole wall is the least with the friction of red needle, red needle is not easily broken, and extends the service life of red needle.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the front view of the workpiece after work pieces process is completed by the utility model.
Fig. 3 is the top view of the workpiece after work pieces process is completed by the utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings detailed description of the invention of the present utility model and operation principle are described in further detail.
As shown in Figure 1 to Figure 3, one takes out the special red needle in hole, including needle body 1 and syringe needle 2, described syringe needle 2 is arranged on the bottom of described needle body 1, the diameter of described needle body 1 is more than the diameter of described syringe needle 2, there is the rectangular pyramid shape blade 3 for tearing workpiece in the bottom of described syringe needle 2, described rectangular pyramid shape blade 3 be shaped as rectangular pyramid and cylindrical overlapping body, wherein cylindrical portion is fixed with described needle body 1 and is connected.
It can also be seen that from Fig. 1, described needle body 1 is made up of canned paragraph 11 and strengthening segment 12, described canned paragraph 11 is connected with the top of described strengthening segment 12, the bottom of described strengthening segment 12 is connected with described syringe needle 2, described canned paragraph 11 and strengthening segment 12 are cylindrical structure, and the diameter of wherein strengthening segment 12 is more than the diameter of canned paragraph 11.
In this example, in order to ensure each face uniform force of syringe needle 2, it is ensured that the service life of red needle, the rectangular pyramid part of described rectangular pyramid shape blade 3 is positive rectangular pyramid.
In this example, according to practical condition, in order to have more preferable using effect, it is 60 ° that the angle of place plane is installed in four faces of the most described rectangular pyramid shape blade 3 with it.
See Fig. 2 and Fig. 3, this red needle is in use, owing to the top syringe needle 2 of red needle is rectangular pyramid shape blade 3, workpiece 4 can be torn when punching, workpiece 4 after tear becomes four shapes of blooming, and scatters from inside to outside, and to be processed hole of taking out can one-shot forming, changing red needle less, production efficiency can improve 10%；The high easily riveting of hole height extracted out, yield rate is high；And hole wall is the least with the friction of red needle, red needle is not easily broken, and red needle improves 75% service life.
