Description

Looping tool strickle and the method for the manufacture of looping tool strickle
Technical field
The present invention relates to a kind of looping tool strickle (Wirkwerkzeugbarre), it is with main body (Korpus), and this main body has longitudinal direction; With circle forming receiving member (Wirkwerkzeugaufnahme), this circle forming receiving member is configured to the fluting lath (Schlitzleiste) with the groove stretched transverse to longitudinal direction (Nut) and bridge part between the grooves (Steg) and utilizes bearing-surface assembly (Auflagefl cheanordnung) to be fixed on main body place, wherein, between the bottom of groove and bearing-surface assembly, be furnished with the join domain for bridge part.
In addition, the present invention relates to a kind of method for the manufacture of the looping tool strickle with main body, this main body has longitudinal direction, in the method, bearing-surface assembly is utilized to be fixed on main body place circle forming receiving member, this circle forming receiving member is configured to the fluting lath with the groove stretched transverse to longitudinal direction and bridge part between the grooves, and wherein, fluting lath has the join domain for bridge part between the bottom of groove and bearing-surface assembly.
Background technology
Such looping tool strickle is known from file DE 103 48 557 B3.
Looping tool strickle is used as, and keeps multiple circle forming of the same type in place and makes its associated movement." circle forming " is interpreted as all such instruments, and namely this instrument participates in looped pile forming process (Maschenbildungsvorgang) during knitted fabric manufacture.Such as knitting needle (Wirknadel), sley point (Legenadel), slip sinker (Schiebeplatine), knocking-over sinker (Abschlagkammplatine) etc. belong to circle forming.
The circle forming fixing at looping tool strickle place must maintain its interval to each other in the operation of knitting machine (Wirkmaschine).In addition, this circle forming must keep it relative to the orientation of other circle forming being fixed on other looping tool strickle place, with the collision in order to prevent the circle forming when moving in the operation of looping tool strickle at knitting machine.At this, importantly temperature change, can produce this temperature change in the operation of warp knitting machine (Kettenwirkmaschine).When temperature change, the length of component can change and the interval of circle forming and position also change thus.
Therefore for a long time fibre-reinforced synthetic material (Kunststoff) is used for the main body of looping tool strickle, wherein, in most cases use carbon fiber as fortifying fibre.When temperature change, in fact carbon fiber reinforced synthetic material does not have length change.
But, only can so process with relatively large cost the main body be made up of carbon fiber reinforced plastics, namely make this main body directly form lopping tool accommodation part.Therefore in most cases, take following measures, be fixed on main body place by circle forming receiving member and circle forming be installed to after a while in this circle forming receiving member.
Be worth it is desirable that, form lopping tool accommodation part by metal in most cases.But most metal has the temperature expansion properties of the temperature expansion properties being different from main body.When the temperature in the surrounding environment at looping tool strickle rises, such as, due to the heat radiation of thread friction or CD-ROM drive motor, circle forming receiving member expands in the mode different from main body.This can cause in disadvantageous state, and looping tool strickle bends.In other situation, in the join domain between circle forming receiving member and main body, there is stress.
Therefore propose starting in file DE 103 48 557 B3 that mentions, the join domain being used in bridge part is so thin, thus thermal expansion only causes shear stress or compression, and it can be absorbed by the connecting portion between circle forming receiving member and main body.This however there is following shortcoming, namely join domain farthest can have the thickness being less than 0.5mm.This makes circle forming receiving member quite responsive (empfindlich).There is following danger, be namely configured to quite thin join domain and be in operation and break or otherwise impaired.
Summary of the invention
The object of the invention is, provide such looping tool strickle, namely this looping tool strickle is relatively durable when operating.
This object is mentioned in the looping tool strickle of type in beginning and being realized as follows, namely makes join domain have and is arranged to spaced at least two meeting stiles (Verbindungsleiste) each other transverse to longitudinal direction.
Thus, although that is bridge part is no longer connected to each other transverse in the extension of longitudinal direction in its whole length.But this neither be necessary, because it is substantially enough to be connected to each other by bridge part two positions.By join domain is divided at least two meeting stiles, in a straightforward manner and it is possible that, the cross section of join domain is reduced so far forth, namely makes temperature improve the longitudinal dilatation no longer causing circle forming receiving member, but cause shear stress or compression in all cases.When correspondingly little cross-sectional area (it realizes by the interval between two meeting stiles), stress can correspondingly keep less.But the comparable meeting stile feasible so far of each meeting stile self is thicker because for shearing or compression substantially only the cross section of join domain be what play a decisive role, and be not separately the thickness of this join domain.
Preferably, at least one intermediate cavity between two meeting stiles, main body has the protuberance extended in longitudinal direction.This protuberance such as has advantage when installing lopping tool accommodation part, because this protuberance can be used as making circle forming receiving member settle orientation at main body place.
At this advantageously, protuberance fills (ausf ü llen) intermediate cavity.In this case be sufficient that, circle forming receiving member is so arranged in main body, namely makes lath abut in protuberance place in both sides.Thus, the reliable orientation transverse to longitudinal direction is obtained.Follow-up connection is especially simplified for bonding, because no longer emit such risk when implementing corresponding Bonding pressure, namely lopping tool accommodation part is shifted transverse to longitudinal direction relative to main body.
Preferably, bridge part is connected with protuberance.Can be such as mutually bonding with protuberance by bridge part.Thus, obtain circle forming receiving member and fix at another of main body place, this is fixing improves mechanical stability further.
Preferably, protuberance is extending over meeting stile in the direction of bridge part.In other words, protuberance is provided with notch, and this notch makes the groove of circle forming receiving member continue.This can such as realize as follows, namely first the blank of circle forming receiving member is fixed on main body place and is after this incorporated into by groove in this blank, such as, by milling or sawing.When producing groove, can be milled into or saw in protuberance completely, and not making the connection between bridge part and protuberance impaired.
Preferably, the meeting stile towards working region stops (abschlie en) in the mode flushed with longitudinal side associated with it.Working region is the region that the participation looped pile of circle forming is formed.So can use the meeting stile be associated with working region, with in order to make circle forming orientation transverse to longitudinal direction.Then circle forming can be abutted in longitudinal side place of circle forming receiving member, and not produce the risk making join domain impaired.As implemented, lath can be configured to enough thickness.
Particularly preferably be at this, the meeting stile towards working region has the extension pointed to away from bridge part in the region of longitudinal side of fluting lath.This extension expands such region, namely circle forming can be abutted in fluting lath place at this region place, namely abut in circle forming receiving member place.This region is larger, then impaired risk is less by circle forming for lath of slotting.
In addition advantageously, longitudinal side associated with it of fluting lath is extended over towards the meeting stile of leg region (Fu bereich).Leg region is corresponding with the other end of circle forming.The leg region of circle forming has protuberance usually, and this protuberance joins in the recess at main body place, with in order to circle forming being positioned at main body place transverse to longitudinal direction.Can use now the meeting stile towards leg region, with in order to improve this location.
Preferably, meeting stile forms the bearing area being used for circle forming.Circle forming now no longer abuts in fluting lath place in the mode of planar over the whole length, but only in the region of meeting stile.Correspondingly, circle forming only also must be provided with bearing-surface in such position, and namely this position is corresponding with meeting stile.Cost for the manufacture of circle forming remains less by this.
Preferably, meeting stile has at least 0.8mm is especially the thickness of at least 1mm.Although this is relatively large thickness.But, because meeting stile has less span transverse to longitudinal direction compared to whole join domain, although so there is larger thickness, but can total cross section of meeting stile be remained so little, namely make temperature improve and do not cause longitudinal dilatation, but cause shear stress or compression.
Preferably, meeting stile jointly forms cross-sectional area, the size of this cross-sectional area is defined as so little, namely make as shear stress or compression between main body and fluting lath owing to heating the expansive force (Dehnungskraft) that causes and compression stress (Stauchkraft) is absorbed in the region of bearing-surface assembly (Auflagenfl chenanordnung), and the length change of lath of avoiding slotting.As implemented above, this realizes by less cross-sectional area, and need not be implemented as by meeting stile self quite thin thus.
This object is mentioned in the method for type in beginning and being realized as follows, that is, use the join domain with at least two laths, this meeting stile has interval to each other transverse to longitudinal direction, and meeting stile is fixed on main body place.
As be combined into above circle tool bar implemented, this design tool has the following advantages, and namely can remain less by total cross section of join domain by use meeting stile, and join domain self need not be made quite thin.Thus, obtain such looping tool strickle, namely this looping tool strickle is not too responsive when handling.
At this preferably, fluting lath to be fixed in main body and after this to produce groove.That is slotted-plate bar is fixed on main body place as blank.This blank can relatively simply be handled and is such as connected with main body by bonding.At this only it is necessary that blank such as has the profile of C shape, be connected with main body at two limit legs of such profile down to major general C.
Preferably, groove is implemented as so dark, namely makes this groove also exist in main body.This is especially favourable in following situation, namely when main body has protuberance (this protuberance is arranged between meeting stile).Can guarantee in a straightforward manner in this case, in the region of meeting stile, in fact only carry out the connection between bridge part, and avoid the continuous print between bridge part to connect in addition, continuous print is connected to when temperature improves can cause problem.
Accompanying drawing explanation
Hereafter also by reference to the accompanying drawings the present invention is being described by means of preferred embodiment.Wherein:
Unique schematic cross-sectional that drawings show through looping tool strickle.
Detailed description of the invention
Only schematically have main body 2 with the looping tool strickle 1 shown in cross section, this main body 2 is substantially formed by carbon fiber reinforced synthetic material when current.Main body 2 has longitudinal direction, and this longitudinal direction points to perpendicular to paper plane.This longitudinal direction extends in the mode of the working width being parallel to looping tool strickle 1.
Looping tool strickle 1 should hold multiple circle forming 3.Be knitting needle as circle forming 3 shown in current situation.Each circle forming 3 has working region 4 and leg region 5.Working region 4 participates in lopping in knitting process.Leg region 5 is used as circle forming 3 to be positioned at main body 2 place in addition.
Arrange lopping tool accommodation part 6 to hold circle forming 3, this circle forming receiving member 6 is configured to lath 7 of slotting.Fluting lath 7 has the groove and bridge part 8 that replace in longitudinal direction.Bridge part 8 extends in parallel relationship at this.Groove is furnished with respectively between two bridge parts.Circle forming 3 can be inserted in each groove.
Bridge part 8 is connected to each other by two meeting stiles 9,10, and this meeting stile 9,10 extends in parallel relationship in longitudinal direction.At meeting stile 9, arrange the interval transverse to longitudinal direction between 10, the protuberance 11 of main body 2 extend in this interval.Protuberance 11 is filled in meeting stile 9, the interval between 10, and that is, when lath 7 of slotting is fixed on the body 2, protuberance 11 can be used as the location that auxiliary member is used as fluting lath 7.
Fix and can such as realize by means of bonding agent 12.Bonding agent 12 is arranged on the whole width of fluting lath 7 between fluting lath 7 and main body 2, that is from fluting lath 7 towards working region 4 longitudinal side 13 until towards longitudinal side 14 in leg region 5, this bonding agent 12 illustrates in excessively thick mode for reason clearly at this.
Protuberance 11 extends over meeting stile 9 in the direction towards bridge part 8, and 10.Bridge part 8 is correspondingly at meeting stile 9, mutually bonding with protuberance 11 between 10.At this, although only realize bonding connection between the narrow side and protuberance 11 of bridge part 8.But bridge part 8 by with meeting stile 9, the connection of 10 (this meeting stile 9,10 is mutually bonding with main body 2 in the both sides of protuberance 11) is stablized in an adequate manner, with make obtain bridge part 8 fluting lath 7 place stable location.Protuberance 11 only extends over meeting stile 9 with less section in the direction towards bridge part 8, and 10.The amount of exceeding such as can have the order of magnitude of about 0.5mm.
Fluting lath 7 to be arranged in main body 2 with the form of the blank not with notch (Schlitze) or groove aptly and to be fixed on this place.After this, the machined grooves between bridge part 8 by milling or sawing.Although groove is only positioned at the surface of protuberance 11, feasible at this, so select the degree of depth of groove, namely groove is also configured in protuberance.
Meeting stile 9,10 have at least 0.8mm, especially the thickness of 1mm.The distance of thickness in this case between meeting stile 9,10 loading end on the body 2 and bridge part 8.
Transverse to longitudinal direction, that is in the accompanying drawings from right towards a left side, meeting stile 9, the span of 10 is obviously short than the span of whole fluting lath 7 in this direction.Correspondingly, relatively less total cross section of meeting stile 9,10 is obtained.But meeting stile 9, this total cross section of 10 is conclusive for tectonic compression or tension between fluting lath 7 and main body 2.When meeting stile 9, when total cross section of 10 can remain less, then circle forming receiving member 6 temperature improve time at main body 2 and meeting stile 9, only form less compression in the bonding agent 12 between 10 or between protuberance 11 and bridge part 8.
Towards the meeting stile 9 of working region 4 to stop with the mode that longitudinal side 13 (this longitudinal side 13 is associated with working region 4) flushes.This meeting stile 9 has extension 15 in addition, and this extension 15 points to away from bridge part 8 and stops with longitudinal side 13 equally.Thus, the relatively large outside of meeting stile 9 is obtained.When whole fluting lath 7 is formed by metal, then fluting lath 7 can be regarded as laths of metal, this laths of metal has relatively large front side, namely such side, and namely this edge surface is to working region 4.This obtains such structure, and namely this structure is relative insensitivity relative to damage.In particular, when inserting circle forming 3, due to the meeting stile 9 with extension 15, the danger of the therefore damage of circle forming receiving member 6 is quite little.
Meeting stile 10 towards leg region 5 extends over the longitudinal side 14 towards leg region 5.This meeting stile 10 can be used as the blocking part of the leg 16 of circle forming.Because lath 10 has relatively large thickness, then such backstop is enough stable, with in order to reliably form the location of circle forming 3 in circle forming receiving member 6.
Aptly, circle forming 3 is placed in two meeting stiles 9, and on 10, to make meeting stile 9,10 form the bearing area being used for circle forming 3.At meeting stile 9, between 10, only there is protuberance 11.But this protuberance 11 is relatively soft (comparing with the meeting stile 9,10 be made of metal), to make lower person enough, namely with meeting stile 9,10 have in the bearing area of contact and process circle forming 3 with desired precision.
