Description
Technical field
The present invention relates to a kind of plastics-looping tool strickle (Wirkwerkzeugbarre), it is with main body (Korpus), and this main body has the upper wall forming upside, the lower wall forming downside and cavity component (Hohlraumanordnung).
Background technology
Known a kind of such looping tool strickle and such method from file EP1820891B1.Wherein, the semi-finished product of planar are put into pressing mold (Pressenform), wherein, flexible pipe is put into pressing mold so together, this flexible pipe is surrounded by semi-finished product.If then close pressing mold and under flexible pipe is placed in certain pressure, so make semi-finished product press to pressing mold from interior.Flexible pipe can be utilized to produce relatively large interior pressure.Can set out thus in approximate first, namely the intensity pressure of main body increases until certain limit, and that is, pressure is larger, and the intensity of main body is larger.
Another possibility for the manufacture of such looping tool strickle is to form sley bar as section bar using extrusion or by pultrusion (Pultrasion).
In the operation of knitting machine, make looping tool strickle reciprocating motion in the opposite direction.Also additionally make some sley bar, such as plaiting sley bar (Legebarre) reciprocating motion on other direction.In each motion, looping tool strickle must be accelerated and brake.The operating rate of warp knitting machine is larger, and the dynamic power be applied to when quality keeps identical in addition on looping tool strickle is larger.The risk of the distortion of looping tool strickle improves thus.Such distortion is again less desirable, because this distortion causes the circle forming being fixed on looping tool strickle place no longer in its theoretical position, thus can produce the collision of coefficient circle forming under adverse conditions.
Summary of the invention
It is high as far as possible that the object of the invention is to make the operating rate of warp knitting machine.
Be arranged to this, cavity component has at least two cavitys, and it is separated each other by rib (Verstaerkung).
Rib causes the reinforcing of main body, and excessively need not improve the quality of main body.
If be furnished with expansion gear at least partially at least one cavity, be also favourable.If use rib, can not directly adopt mode known from file EP1820891 again, because rib and expansion gear mutually conflict in the inside of main body.Solve this problem thus now, namely at least one cavity of cavity component, arrange that expansion gear at least partially.So can, with the wall of desired high pressure-loaded around this cavity, it be made to obtain high intensity.
Preferably be arranged to, in each cavity, be furnished with expansion gear at least partially.In this case, expansion gear is divided, makes the part being furnished with expansion gear on the both sides of rib.Pressure in desired by this expansion gear so can produce in each cavity, thus the main body with high strength also can be constructed as up to now.
Preferably, rib is arranged between upper wall and lower wall.Reason for iconicity selects concept "up" and "down".Also upper wall can be called " the first wall " and also lower wall can be called " the second wall ", correspondingly, also upside can be called " the first side " and downside be called " the second side ".So upper wall in one direction as main body boundary and lower wall is arranged as the boundary of main body in the opposite direction.Rib reinforces looping tool strickle so in the direction in which.This has multiple advantage.On the one hand, this rib reacts on the flexure of looping tool strickle due to horizontal acceleration, static load and/or detrusion.This is especially favourable for the knitting machine with large working width (it can reach until 6m).
At this preferably, rib has than rigidity larger in a second direction perpendicular to the first direction at first direction (it stretches from upper wall to lower wall and/or in the longitudinal direction of looping tool strickle).Relatively little quality can be utilized thus to increase the reinforcing of realization body.Need not excessive thick ground and design rib to large quality thus in a second direction.If rib in a first direction, namely in the longitudinal direction of looping tool strickle or to the direction of lower wall or in its combination, there is the rigidity of expectation from upper wall, just enough.
Preferably, rib is configured to plate, is especially flat plate.Plate length with on width, namely on main inertia direction, there is relative large rigidity and there is less rigidity in a thickness direction.This anisotropy can be used for now reinforcing the direction providing expectation.Meanwhile, the quality of rib keeps less.If plate is configured to flat plate, so it has maximum rigidity in this plane, that is there is not the prebuckling that can increase when being out of shape.This rib is not necessarily continuously along looping tool strickle-extending longitudinally.It also can have the discontinuities matched to the corresponding load of looping tool strickle.
In an alternative design, rib can be configured to hollow profile, especially be (schlauchgeblasen) hollow profile of flexible pipe blowing.This hollow profile was made into before it is placed in pressing mold as rib together with the semi-finished product of planar.This hollow profile so provide except two cavitys be separated each other the 3rd cavity for, thus obtain the structure of the multi-cavity of main body, its deformation drag causing again the rigidity of improvement and improve thus." flexible pipe blowing " hollow profile is can with the section bar manufactured with similar mode illustrated in file EP1820891B1.Namely such as produce this hollow profile thus, that is, the semi-finished product of planar are put into pressing mold and within pressure-loaded.As illustrated in file EP1820891B1, this interior pressure produces by gas (it is imported in the flexible pipe be arranged in the inside of hollow profile).Other expansion gear is also possible certainly.Concept " flexible pipe blowing " is used to the object of abridging here.But also can use otherwise such as by the hollow profile extruded or pultrusion manufactures.
Preferably, hollow profile has bearing-surface (Aufstandsflaeche), especially flat bearing-surface on upper wall and/or on lower wall.Very accurately rib may be located thus when manufacturing main body.Bearing-surface allows the position by hollow profile is being expected to be placed on semi-finished product.Hollow profile can be fixed on upper wall and/or lower wall with bearing-surface if desired, such as, pass through adhesive.Be preferably used for manufacturing the prepreg (Prepreg) of main body but repeatedly there is certain viscosity, thus no longer need in many cases to add fixing.
Preferably, rib remains in shaping lath (Formleiste) (it is arranged into the inwall place of main body).Shaping lath makes rib fixedly become possibility equally in precalculated position.It allows by form fit or resistance location rib.In applying during pressure, shaping lath prevents rib from moving.
Can be arranged in an alternative or additional design, rib stretches in the inwall of main body.To this, the inwall of main body can have recess.Such recess is not critical, because its portion of being reinforced fills and the actual intensity not damaging main body thus.Additionally, rib is fixed better.
At this preferably, main body outwards has at least one forming section (Ausformung) in the region of rib.This forming section can be arranged in pressing mold or by tool bar (Werkzeugleiste) and be formed.Rib is so kept by form fit and is fixed in its position.Forming section can be used as the additional functional surfaces of looping tool strickle, such as backstop, screw face, bonding plane etc.
Can be arranged in an alternative or additional design, main body has at least two briquet section bars (Barrenprofil), wherein each has cavity and it correspondingly reclines each other mutually with sidewall, and wherein, these two sidewalls form rib jointly.Namely main body is made up of multiple elements, to obtain the structure with multiple room thus.Rib can very stably construct in this case, because in these two sidewall actings in conjunction.
At this preferably, side-wall material is interconnected ordinatedly.Material fit such as realizes by bonding or welding.Also can, by suitable solvent or the surface of otherwise dissolving at least one sidewall, the material of this sidewall can be connected with the material of another sidewall.
At this preferably, at least one briquet section bar overlaps another briquet section bar in the region of sidewall.Thus, the mechanical enhancer of main body is additionally obtained.

Fig. 4 shows the schematic sectional view of the 3rd form of implementation of looping tool strickle.
Detailed description of the invention
Fig. 1 extremely show schematically show looping tool strickle 1, and it is formed primarily of plastics.Sley bar 1 has main body 2, and it has the upper wall 4 forming upside 3 and the lower wall 6 forming downside 5.Concept "up" and "down" or " upside " and " downside " relate to diagram in the accompanying drawings and are chosen to can distinguish wall and side in a straightforward manner.When looping tool strickle 1 is installed in knitting machine, it not necessarily provides again these relations.At this, looping tool strickle 1 can relative to the illustrated example in accompanying drawing as half-twist be installed.
The housing region 7 of the circle forming for not being shown specifically is provided with at main body 2 place.
Main body 2 has cavity component.In the present embodiment, cavity component has two cavitys 8,9.Rib 10 is furnished with between these two cavitys 8,9.In the present embodiment, rib 10 has the form of plate 11.This plate 11 such as can be configured to filled board, namely be formed by multiple layers.It can have fiber strengthened plastics, especially carbon fiber-reinforced plastics.It also can have stiff foam material.Plate 11 is configured to flat plate.Along the structure that this is flat, plate 11 has relatively large rigidity.Correspondingly, plate 11 causes the reinforcing of the main body 2 of looping tool strickle 1 between upper wall 4 and lower wall 6.
Plate 11 is fixed on upper wall 4 place by means of shaping lath 12.Shaping lath 12 has two protuberances 13,14, and it extends perpendicular to plotting planes, be that is parallel to the extending longitudinally of main body 12 stretches.Being of uniform thickness of spacing between these two protuberances 13,14 and plate 11 is large.Protuberance 13,14 can be configured to Prepreg strip simply, and it is formed by with the wall 4 of main body 1,5 identical materials.
In the region of lower wall 6, plate 11 stretches into and stretches in upper wall 4 in the wall of main body 2, that is.To this, upper wall 4 outwards has forming section 15 in the region of plate 11.
A part for expansion gear is furnished with in each in two cavitys 8,9.In present case, expansion gear constructs by means of flexible pipe 16,17, and it can be placed in pressure from outside, such as, pass through compressed air.These flexible pipes 16,17 can be retained in cavity 8 and also can after fabrication from the interior walls abutting in cavity 8,9.
In present case, sley bar 1 manufactures in pressing mold 100.Pressing mold 100 has the first half 101 and Lower Half 102.Insert 103 is furnished with in Lower Half 102.Insert 103 has recess 104, and it is used to manufacture forming section 15.
In order to manufacture looping tool strickle 1, preferably pressing mold 100 will be put into the semi-finished product of the planar of the form of prepreg.This semi-finished product are placed around rib 10 around two flexible pipes 16,17 at this.In housing region 7, half-finished end can overlap.Then pressing mold 100 is closed.Under two flexible pipes 16,17 can being placed in pressure afterwards, semi-finished product (forming wall 4,6 and remaining main body 2 after it) are made to be close to pressing mold from interior and press with relative large pressure there.Pressure is larger, and the intensity of main body 2 is higher.
Certainly this pressure is also applied on plate 11.But this is not critical, because the pressure adjustable in cavity 8,9 saves into make identical power from double side acting to plate on 11.It is even possible that plate 11 is provided with hole or recess.Such hole is not critical yet, because as described, can set up identical power or pressure on both sides.
Before insertion plate 11, such as, the protuberance 13,14 of the shaping lath 12 as Prepreg strip can be applied on semi-finished product by bonding, or it can be used to fixed head 11 after plate 11 inserts.
Also pressure in can otherwise, namely applying when not having flexible pipe 16,17.One possibility is also to be directed in cavity 8,9 by corresponding Compressed Gas when not having flexible pipe 16,17.Another possibility to be the material of expansion, such as foamed material etc. to be loaded in cavity 8,9 and to make it expand there.If desired, need to use the temperature improved at this.
Replace the manufacture in pressing mold 100, also manufacture sley bar 1 by extrusion or by pultrusion.In this case, although under cavity 8,9 is not placed in corresponding pressure.But, by rib 10, the rigidity that main body 2 is improved.In this case, main body 2 and rib 10 construct aptly integratedly.
