In braiding machine or knitting machine, the lopping knitting needle is used as into coil element and is coupled with control element, and here, pin and control element be loose engagement each other, and remains attached to together by the side direction guide portion in the guide groove.
In braiding or knitting method process, the syringe needle of pin plays decisive role basically for lopping.Therefore syringe needle must be constructed design corresponding to relevant lopping method.In addition, syringe needle also is subjected to strong wearing and tearing.Produce very big problem thus.Must provide a large amount of heteroid pins corresponding to different knitting or braid method processes for use.The strong wear of syringe needle has determined often to change pin damage or fracture.For the manufacturing of pin, if the material that the high abrasion resistance strength of syringe needle requires, material cost and the manufacturing cost that then can significantly amplify pin are satisfied in employing.
Know from DE 23 30 474 A1, make shank and syringe needle dividually for addressing this problem.For shank, can the low flat material (as band steel) of use cost; And, then use different material corresponding to the syringe needle demand for syringe needle.Shank and syringe needle are combined by welding or welding, and as a whole pin is connected to each other.Thus, the lopping knitting needle can be made corresponding to different operating positions.Because shank has been selected different materials for use with syringe needle, so also can reduce manufacturing cost.Yet, therefore under the situation of wearing and tearing or pin fracture, also must change whole lopping knitting needle because syringe needle and shank are firmly combined lastingly.
Summary of the invention
The objective of the invention is to, a kind of lopping knitting needle is provided, its cost is low, and can adapt to different operating positions.
According to the present invention, above-mentioned purpose is achieved by the lopping knitting needle with claim 1 feature.
Favourable embodiment of the present invention provides in the dependent claims.
According to the present invention, the shank of lopping knitting needle and syringe needle are as the part manufacturing that separates.Then this shank and syringe needle shape are combined sealedly, wherein, shank and syringe needle are engaged with each other by the mode of a line of demarcation of extending in the plane of flat material with the tooth engagement.Here, on the direction vertical with the plane of flat material, shank and syringe needle cooperate in discerptible mode each other.Shape makes that with gapless being engaged with each other of tooth engagement system being directed to its motion in guide groove remains attached to together just as a monoblock type pin sealedly in the plane of flat material.Yet shank and syringe needle can merge perpendicular to the set of planes of flat material and can also separate again.If pin is in the state of installing in the guide groove, then the side direction guide portion in the groove can prevent separating of shank and syringe needle reliably.
Because shank and syringe needle make up in discerptible mode, so shank and syringe needle can be with different material manufacturings.This material can require and material cost and manufacturing cost are selected according to machinery, and can freely make up each other.Particularly, shank can be formed by the flat material punching out, preferably as sheet material punching out part particularly by the steel plate manufacturing.The syringe needle material manufacturing of satisfying high fracture strength and high abrasion resistance strength requirement especially.Particularly, syringe needle can be by metal, pottery, plastics, powdered metallurgical material or a kind of composite manufacturing.Particularly, syringe needle also can be used the metal injection moulding manufacturing, as described in DE 10 2,005 028099 B3.Make shank and syringe needle by different materials and with different manufacture methods, can reduce material cost, and make shank and syringe needle optimally be matched with different mechanical requirements.
Another advantage is, a kind of same shank and heteroid syringe needle can be made up.For different syringe needle types, can make the shank of a large amount of numbers uniformly, just reduced manufacturing and warehouse cost thus.
At last, an important advantage is, needn't change whole lopping knitting needle when syringe needle wearing and tearing or fracture.Can only change the syringe needle of damage, shank then can continue to use.Also can greatly save cost thus.
Description of drawings
Describe the present invention in detail according to embodiment illustrated in the accompanying drawings below.In the accompanying drawing:
Fig. 1 represents the lopping knitting needle of first embodiment with side view;
Fig. 2 is the corresponding diagram of second embodiment;
Fig. 3 is the corresponding diagram of the 3rd embodiment;
Fig. 4 represents the lopping knitting needle with the control element coupling.
The specific embodiment
Lopping knitting needle 10 has shank 12, is provided with syringe needle 14 at the front end of this shank 12.In the rear end relative of shank 12 with syringe needle 14, lopping knitting needle 10 can with control element 18 couplings, for example as Fig. 4 represents with demonstrating.For this reason, control element 18 embeds in the fossa glenoid 22 of shank 12 with ball and socket joint 20.Shank 12 is provided with control element 18 is loosening each other by this way, and remains attached to together at the guide margin of side direction by a guide groove, and pin 10 is directed in this guide groove with control element 18.In the plane of shank 12 and control element 18, they can be around joint 20,22 each other with a restricted angular deflection.
Self-evident, the structure design of other of syringe needle 14 also is fine.Equally, the shank end at rear portion and with other structure designs of control element coupling also be possible.
In this regard, this lopping knitting needle 10 is consistent with prior art, all should comprise in the present invention from change/modification known in the art.
Different with known systems, according to the present invention, shank 12 and syringe needle 14 are two parts of separately making.Syringe needle 14 is as the part manufacturing of preferably using punching of the steel plate with flat material (as band steel).Syringe needle 14 usefulness metals, pottery, plastics, powdered metallurgical material or a kind of composite manufacturing.The selection that is used for the material of syringe needle 14 is determined by fracture strength, scuff resistance and process technology.Particularly, syringe needle 14 also can be used metal injection moulding (metal injection molding) manufacturing, and what for example illustrate in DE 10 2,005 028099 B3 is such.
For shank 12 and syringe needle 14 are combined, end section 34 is fitted to each other sealedly with the tooth engagement system with shank 12 shapes.Thus, shank 12 and end section 34 contact along a line of demarcation of extending in the plane of flat material 36.At this, extend like this in line of demarcation 36, that is, make syringe needle 14 in the plane at the flat material of shank 12 on the shank 12 seamlessly and shape sealedly both also on the short transverse of pin 10, kept on the lengthwise bearing of trend at pin 10.
In vertical plane, the plane of the relative flat material of shank 12, that is in plane perpendicular to the figure paper plane, shank 12 and syringe needle 14 36 cooperate each other like this along the line of demarcation, make syringe needle 14 and shank 12 by rubbing sealed the maintenance (connection), but can also separate again each other to syringe needle 14 applied pressures by a plane perpendicular to flat material.Sealed being enough to of such friction remains on the purpose of syringe needle 14 for assembling on the shank 12.At run duration, the zone in line of demarcation 36 is directed seeking between the side of groove, thereby makes syringe needle 14 and shank 12 not to move relative to each other perpendicular to the plane of shank 12 and can not unexpectedly separate each other.
The extension in line of demarcation 36 trend can freely be selected to a great extent, only need guarantee here that in the plane of flat material shape is sealed on all directions.Line of demarcation 36 also should have enough length in addition, so that guarantee that enough frictions that syringe needle 14 and shank 12 are connected together are sealed.
In the embodiment in figure 1, extend perpendicular to the longitudinal axis of pin 10 in first section 36.1 in line of demarcation 36, is connecting second section 36.2 that a longitudinal axis with pin 10 extends in parallel on it.At front end, on this second section 36.2, connecting one the 3rd section 36.3, the three sections again transverse to the longitudinal extension of pin 10, still recede a little, thereby it is recessed to have produced a side.In stage casing 36.2, line of demarcation 36 forms the section 36.4 of a projection, and this section embeds in the end section 34 of syringe needle 14.Section 36.4 broadenings of projection make that its side of the same formation in front and back is recessed.The section 36.4 of this projection makes syringe needle 14 and shank 12 shape on pin 10 vertical be connected sealedly.The side of section 36.4 the side of section 36.3 and projection is recessed to cause that to obtain a kind of shape on the short transverse longitudinally perpendicular to pin 10 sealed.
Fig. 2 expresses a kind of extension trend that changes to some extent in line of demarcation 36.Different with the embodiment of Fig. 1, first section 36.1 relative pin 10 vertically also to depart from 90 ° of angle lappings oblique, make this first section 36.1 also to play the recessed effect of side, the shape that it has been strengthened on short transverse is sealed.
Fig. 3 expresses the extension trend that the another kind in line of demarcation 36 changes to some extent.In this embodiment, first section 36.1 longitudinal axis perpendicular to pin 10 extends.Be parallel to second section 36.2 front-end edge that always reaches shank 12 that needle axis is extended, so that cancelled the 3rd section 36.3.In this embodiment, perpendicular to the sealed only front of the section 36.4 by projection of the shape on the short transverse of the longitudinal axis of pin 10 and recessed being achieved of side of back.
