Technical field
The present invention relates to a kind of sley bar (Barre) that is used for warp knitting machine, it has body (Korpus), and this body has the carbon fiber reinforced plastic material and holds pin portion (Nadelaufnahme).
The invention still further relates to a kind of manufacturing and be used for the method for the sley bar of warp knitting machine, the body that wherein has the carbon fiber reinforced plastic material is provided with the pin portion of holding.
Background technology
The sley bar that is installed in the warp knitting machine must at least once quicken at an action direction in a knitting circulation usually, and at least once quickens in the opposite effect direction.To quicken necessary trying hard to keep and hold lessly in order to make, people efforts be made so that the quality of sley bar keeps less.Also go for high mechanical robustness simultaneously.Therefore this sley bar is used in suggestion several years ago: it has the body of carbon fibre reinforced plastic.Have relatively little weight and relative good mechanical robustness by the carbon fiber reinforced plastic material.
Sley bar is supporting carrying out the essential knitting needle of braiding process.For example can be meant the sley point that is used to produce decorative pattern at this.
In order knitting needle to be fixed on the body, to be provided with the pin portion of holding.
To by the disclosed sley bar of DE 103 48 557 B3, hold the pin cage structure in bonding jumper, this bonding jumper sticks on the body.Problem in this case is that metal has the thermal expansion different with body.The manufacturing of this sley bar is difficult in addition.At first, having the bonding jumper of holding pin portion must size accurately process, and the position accurately sticks on the body then.Must be noted that at this, form uniform glue-line and not comprise bubble.Two parts must totally and not have oil this moment.Under by the disclosed situation of DE 103 48 557 B3, bonding jumper has the bar base of constructing relatively weakly, like this bonding jumper is related to highstrung part.Therefore have very big risk, promptly bonding jumper is distorted constantly in operation.This causes additional difficulty in the time of may be on pasting body.Another shortcoming is that this taping process skillfully is a prerequisite with significant handicraft.This is not that each people who is engaged in the processing of this sley bar has.
In EP 1 600 543 A1, advised another kind of solution.The branch groove that later stage will be used for supporting knitting needle directly mills out at body at this.The zone that will mill out the branch groove of body is configured to local at least the enhancing.This method proves effectively, and provides and hold pin portion relatively accurately.But this method relative cost is very high, because it is very fast relatively to be used for the tool wear of milling.
Summary of the invention
Task of the present invention is that simple and cost is made the sley bar that is used for warp knitting machine economically.
For the sley bar of the described type of beginning, this task is finished thus, is about to hold the pin cage structure in plastic coating, and described plastic coating is coated with and is contained on the described body, and the described pin portion of holding has the groove that processes in the plastic coating of sclerosis.
With plastics coating on the body of sley bar.Although this process requires certain precision equally.Precision when but this precision is less than the stickup bonding jumper.Behind the application plastic coating, be provided with and hold the essential depression position of pin portion.By the corresponding selection of plastic material, can realize that plastics are enough firm in fixing knitting needle.And the relative carbon fiber reinforced plastics of cutter are subjected to littler resistance, and the wearing and tearing of cutter can keep less like this.By plastic coating is coated with install on the body after machined grooves, can make and hold pin portion and very accurately locate with respect to body.
Preferred plastic coating is made of the plastics that are viscosity under unhardened state.In other words, the plastic cement stick can be coated with and be contained on the body, in any case be connected with body very securely in its short time when application or after application.Preferred this being connected when hardening realized.No longer need the Connection Step that adds thus at all.The plastic cement stick of work hardening relatively simply in addition.The intensity of the plastic cement stick of sclerosis is enough big, so that knitting needle is remained in position.Here be noted that and on single knitting needle, only act on limited power.
Preferably hold pin portion and have the groove that in plastic coating, mills out.Milling is the method that is used to make groove of relative price economy.For example can use circular peripheral-mill for this reason.
Preferably hold the lug boss that pin portion has two parallel lay-ups.Each knitting needle is fixedly secured on two points that have certain distance mutually.Thus knitting needle is supported in the sley bar reliably, thereby although it side force occurs at this but still cannot be displaced sideways in the braiding process.And also keeping material consumption less simultaneously, the quality of sley bar keeps less like this.
Preferred at this, this lug boss is disconnected from each other.Can between fixing point, realize big relatively distance thus.
Preferred plastic coating is made of the bi-component binding agent.The bi-component binding agent two kinds of components in conjunction with the time just begin the sclerosis.If can guarantee this advantage, can certainly use more than two kinds of components.Single component just can be mixed in the short time before application.Simplify processing thus.The danger that binding agent in the disadvantageous moment sclerosis takes place keeps less.The bi-component binding agent can be adjusted so in addition, makes it harden relatively soon.Correspondingly, need the less time for the manufacturing of sley bar.
Preferred plastic coating is made of the plastics of polyurethane-base (Polyurethan-Basis).This plastics are mechanically enough firm, and quality is enlarged markedly.
For the method for the described type of beginning, this task is finished thus, and promptly plastic coating is coated on body, and in this plastic coating groove is set.
Be contained on the body by at first plastic coating being coated with, and machined grooves then, manufacturing will be simplified greatly.Needn't use responsive member, as the bonding jumper that has a groove that has processed is fixed on the body will hold pin portion.Hold pin portion on the contrary directly on the body, promptly in plastic coating, produce.Can construct plastic coating like this, make its not excessive wear for the employed instrument of machined grooves.
Preferably constitute plastic coating by adhesive at this, it hardened before machined grooves.The application of this adhesive or binding agent has this advantage, and promptly plastic coating itself is connected with body when application to a certain extent.Therefore no longer need to add, be used for plastic coating and body step of connecting.
Preferably when the plastic coating application, the longitudinal direction that is parallel to sley bar produces the depression position at the center of plastic coating.Realize that thus each knitting needle can be supported on two points of arranging at spaced-apart certain distance on the longitudinal direction of knitting needle.Can prevent the excessive restriction when knitting needle is fixed in the sley bar thus.Not need to guarantee the material that adds here by the depression position simultaneously.Can make the quality of sley bar keep less thus.
Preferred at least two parallel plastics protrusions of application on body.Producing the depression position at the center of plastic coating is special simple proposal.This depression position produces simply thus, i.e. not application plastics between parallel plastics protrusion.
Preferably plastics are sprayed from nozzle arrangements (Duesenanordnung).Have suitable denseness if be used to produce the plastic material of plastic coating, then can utilize respective nozzles in an operation, to produce cross section arbitrarily.For example can utilize the glue spreader of pneumatic or hydraulic pressure and utilize automatic feeding to make the uniform cross-sectional area of any length.For example, then for example use the cross section that the respective nozzles shape can form plastic coating with the shape of the best by making above mentioned depression position.
The preferred nozzle arrangements that uses with a plurality of outlet openings.If want the two or more parallel plastics protrusions of application on body, this is particularly advantageous.
The preferred bi-component binding agent that uses is as plastic coating.This binding agent can for example be formed by synthetic resin.It is handled then like this, makes it in the correct time, just be coated with and harden after installing on the body.Because the bi-component binding agent can be adjusted like this, make it harden relatively apace, can make manufacturing time shorter relatively.
The preferred binding agent of polyurethane-base that uses is as plastic coating.This binding agent with enough robustnesses be connected by the made body of carbon fiber reinforced plastic material.It has essential mechanical robustness to guarantee fixedly knitting needle in addition.
