Abstract
The invention discloses an extrusion needle point and a perforating needle. The extrusion needle point comprises a fixing section fixed to the extrusion needle, a work section and a conical section. The work section is used for extruding a seamless pipe, and the size of the circumscribed circle of the work section is larger than that of the circumscribed circle of the fixing section. The conical section is used for connecting the work section with the fixing section. During use, the extrusion needle point is fixed to the extrusion needle through the fixing section, the work section and the fixing section are connected through the conical section, the circumscribed circle of the work section is larger than that of the fixed section, in other words, inverted conical connection is achieved, and therefore the seamless pipe larger than the type of the extrusion needle in size can be machined. The type of the extrusion needle does not need to be replaced, and therefore the length of the seamless pipe cannot be affected. The extrusion needle point can produce the seamless pipe with the inner hole size larger than the specification of the extrusion needle under the premise that the fixed-size length is achieved, and the problems in the prior art are solved.
Description
Technical field
The present invention relates to extruder member field, more particularly, it relates to a kind of extruding needle point and pecker.
Background technology
In field of extrusion, pecker, as the vitals in this technical process, is employed extensively.And in operation, be
Save metal material, simplify the replacing program of part, generally pecker is divided into two parts, i.e. squeezing needle and needle point, in reality
During border produces, only need to change needle point to realize the extruding to products of different specifications.Therefore, when making seamless tubular goods, needle point
Structure directly affects size and the quality of seamless tubular goods inner surface.
For the production of different product, the specification of the standing squeezing needle of producer is less than five, and under normal circumstances, needle point
Work band circumscribed circle size be respectively less than squeezing needle working size.When extruding sectional area is larger and hole size is slightly larger than
During the working size of a certain specification squeezing needle, according to the squeezing needle of bigger specification, on the premise of the equal consumption of raw material,
The length of the seamless tubular goods squeezing out can be shortened；And the recipient mating specification, this mistake need to be changed while changing squeezing needle
Journey complex operation, and so that production efficiency is reduced.
Therefore, how on the premise of meeting tubing measured length, produce the hole size nothing bigger than the specification of squeezing needle
Slit-tube material is this field difficult problem urgently to be resolved hurrily at this stage.
Content of the invention
In view of this, it is an object of the invention to provide a kind of extrude needle point, this extruding needle point can meet sizing
On the premise of length, produce the hole size seamless tubular goods bigger than the specification of squeezing needle, solve a difficult problem of the prior art.
The present invention also aims to providing a kind of pecker, this pecker includes above-mentioned extruding needle point, therefore, it is possible to fixed in satisfaction
On the premise of dimensions length, produce the hole size seamless tubular goods bigger than the specification of squeezing needle.
A kind of extruding needle point, including：For the canned paragraph mutually fixing with squeezing needle, for alloy extruded seamless tube and external
Circle size is more than the active section of described canned paragraph, for connecting the conical section of described active section and described canned paragraph.
Preferably, described extruding needle point, also includes：It is arranged between described conical section and described active section, be used for playing
The linkage section of transitional function.
Preferably, described extruding needle point, also includes：It is arranged on the end of described active section, be used for dismounting described squeezing needle
The handle of point.
Preferably, described extruding needle point, the outer peripheral face of described canned paragraph is provided with for mutually fixing with described squeezing needle
Screw thread.
Preferably, described extruding needle point, described handle is prismatic.
Preferably, described extruding needle point, described handle is provided with the through hole of radial direction.
A kind of pecker, includes the extruding needle point as above described in any bar.
The extruding needle point that the present invention provides, including：The canned paragraph fixing with squeezing needle phase, for alloy extruded seamless tube and
Circumscribed circle size is more than the active section of described canned paragraph, for connecting the conical section of described active section and described canned paragraph.Use
When, extruding needle point is fixed with squeezing needle phase by canned paragraph, this active section is to be connected by conical section with canned paragraph, and work
The circumscribed circle making section is more than canned paragraph, and as inverted cone connects, therefore it is bigger than the size of this model squeezing needle to play processing
Seamless tubular goods；Because the model of squeezing needle need not be changed, therefore the length of seamless tubular goods will not be impacted.Therefore, this squeezing needle
Point can produce the hole size seamless tubular goods bigger than the specification of squeezing needle on the premise of meeting sizing length, solves
A difficult problem of the prior art.
Brief description
In order to be illustrated more clearly that the embodiment of the present invention or technical scheme of the prior art, below will be to embodiment or existing
Have technology description in required use accompanying drawing be briefly described it should be apparent that, drawings in the following description be only this
Some embodiments of invention, for those of ordinary skill in the art, on the premise of not paying creative work, acceptable
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is the schematic diagram extruding needle point in the specific embodiment of the invention.
In Fig. 1：
Canned paragraph 1, active section 2, conical section 3, linkage section 4, handle 5, screw thread 6, through hole 7.
Specific embodiment
The core of this specific embodiment is to provide a kind of extruding needle point, and this extruding needle point can meet scale modest ability
On the premise of degree, produce the hole size seamless tubular goods bigger than the specification of squeezing needle, solve a difficult problem of the prior art.
Hereinafter, referring to the drawings embodiment is illustrated.Additionally, embodiments illustrated below is not to described in claim
Content of the invention play any restriction effect.In addition, the full content of the composition represented by example below is not limited to as right
Require necessary to the described solution of invention.
The extruding needle point that this specific embodiment provides, including：Canned paragraph 1, active section 2, conical section 3.Wherein canned paragraph 1
For being connected with squeezing needle；Active section 2 is used for alloy extruded seamless tube, and the size of its circumscribed circle is more than the external of canned paragraph 1
The size of circle；Conical section 3 is used for connecting active section 2 and canned paragraph 1.The present invention with respect to extruding needle point of the prior art,
Big difference is coupling part to be changed to inverted cone so that the size of active section 2 is more than canned paragraph 1, thus realizing producing ratio
The big seamless tubular goods of the model of squeezing needle.During use, extruding needle point is fixed with squeezing needle phase by canned paragraph 1, this active section 2
