Abstract
This invention relates to a fabricating method for circle forming bracket, where, A circle forming tool (2) is put into the molding die and loaded by composite material. Said invention is aimed at providing a low cost fabricating method, therefore, the composite material (3) should be cooling at a temperature point of no more than 60 centigrade degree from a temperature point of being in a fluid condition.
Description
Technical field
The present invention relates to a kind of method of making circle forming bracket, wherein circle forming is put into formation mould, and load with synthetic material.
Background technology
Term " become figure instrument " be meant knitting machine, particularly warp knitting machine at this those when producing knitwear, participated in the abbreviation of the element of lopping.Therefore, it not only is meant circle forming originally, and for example knitting needle, slide bar, pusher jack and similar articles also instruct the yarn element, for example sley point, comb shape pusher jack or similar articles.
Circle forming in the warp knitting machine is arranged side by side in a large number.In order to make their operations easier, several one-tenth figure instruments are combined respectively in groups, and are fixed in the support.Can be installed in these circle forming brackets in the needle bar pad of warp knitting machine or on the needle bar pad then.
Known a kind of tool holder from DE 102 27 532 B4, it is used for the machine of lopping, and wherein said instrument is connected with each other by the synthetic material body.In a kind of structure, the synthetic material body passes instrument.In the another kind structure, enclose to the synthetic material body portion these instruments that blocks.The synthetic material body is a pressure injection body at this.After support is made, also need circle forming is carried out expensive reprocessing, be used for making instrument to reach final portrait orientation and collimation.
DE 196 18 368 A1 have described a kind of device, and its thread-guide element and supporter by warp knitting machine or knitting machine is formed, and described supporter has groove at this, and this groove is filled with hardenable filler.Circle forming is meant sley point at this, in the also unhardened filler of packing into.In this method, circle forming must at a good pace be packed in the described supporter, just before the filler sclerosis.Because can not guarantee that filler can be pushed equably in no problem ground when circle forming is packed into, so also have such risk at this, being the lopping instrument also must reprocess after manufacturing process originally, is used for making their directed in parallel to each other, and expectation vertically on alignment.
Summary of the invention
Task of the present invention is to provide a kind of cost favourable manufacture method.
This task is achieved in the method for described type in front like this, promptly synthetic material is being cooled to 60 ℃ temperature at the most from its temperature that is flow-like within 3 seconds at the most.
In this method of operating, the orientation of circle forming is carried out in formation mould.Just circle forming is placed in the formation mould with final portrait orientation and the collimation of pursuing.If insert in the formation mould subsequently and make its sclerosis, will form the circle forming bracket of expectation to synthetic material.But because the time that high temperature exists is quite short, formation mould and circle forming are not all heated significantly, so can not produce stress in the material of circle forming, described stress may make circle forming fault orientation each other.Synthetic material surrounds circle forming by the cooling form fit with connecting, has therefore just made at synthetic material sclerosis back circle forming bracket.Described being hardened under the temperature that is lower than 60 ℃ carried out.Circle forming is adding man-hour and almost keeping identical temperature fixedly the time in synthetic material.Yes in small temperature rising inevitably.But, also be limited so this temperature raises because the importing of heat can be limited in the quite short time period.
Preferably, synthetic material is being cooled to 30 ℃ temperature at the most in 3 seconds at the most.Therefore also a spot of heat can be in circle forming, imported, thereby also less stress may be in the material of circle forming, produced.
Preferably, synthetic material was heated to the temperature of the scope that is in 180 ℃ to 250 ℃ before putting into formation mould.In this temperature range, the liquidity of synthetic material can make it to join in the formation mould no problem.On the other hand, the also low degree that can fully cool off apace to synthetic material of this temperature.If synthetic material self is not cooled to 60 ℃ at the most, 30 ℃ preferred temperature at the most particularly in the described time, can correspondingly realize that then temperature descends fast by dispelling the heat targetedly from the outside.
Preferably, with the pressure in 3 to the 40 crust scopes synthetic material is added in the formation mould.Therefore formation mould can be filled with the low pressure pressure injection.Owing to avoided high pressure, so avoided extra stress too.In addition, only needing very little power in the synthetic material adding formation mould.This has reduced power consumption, and therefore described method is seen on energy point of view also and can advantageously be implemented by cost.
Preferably, use polyamide as synthetic material.Rong Hua polyamide highly, it adds in the formation mould with small pressure, can fully cool off apace and also solidify simultaneously, but so the circle forming form fit be enclosed in the support with connecting.Can cancel the high post processing of cost, particularly orientation works again.Another advantage is, this synthetic material in light weight.
Description of drawings
By preferred embodiment the present invention is described in conjunction with the accompanying drawings below.Wherein:
Unique Fig. 1 shows the schematic views of the circle forming bracket with pusher jack.
The specific embodiment
Circle forming bracket 1 has a plurality of pusher jacks 2, and they are synthesized materials for support body 3 together and fix.For making this support, the formation mould that is not shown specifically is put into and be fixed on to pusher jack 2.Final portrait orientation and collimation that pusher jack 2 is pursued are carried out at this.
Formation mould has cavity, and its shape is corresponding with the shape of later supporter 3.The highly polyamide of fusion is housed in this cavity, it is encased in the formation mould with small pressure, for example with the pressure in 3 to the 40 crust scopes, wherein preferably, this pressure is in the bottom of described pressure limit, just especially in the scope of 3 to 10 crust.
Before synthetic material is inserted in the formation mould, it is heated to about 200 ℃.Can be less than 3 seconds, particularly synthetic material is being cooled at the most 60 ℃ or even 30 ℃ temperature at the most within about 2 seconds now.Preferably use the synthetic material that in the described time period, carries out corresponding cooling at this.If the cooling velocity of synthetic material is too slow, then can reach the cool time of expectation by the heat radiation of outside.
Because in fact the effect limits that temperature improves in the short relatively time period, so formation mould and pusher jack 2 can not be heated significantly, therefore can not produce negative stress in the material of pusher jack 2.
Synthetic material is for example solidifying in time period of 2 seconds simultaneously, and the connection of pusher jack 2 form fit be enclosed in the supporter 3.
In this method of operating, in the fixation procedure in the manufacturing procedure process and in support, pusher jack 2 nearly all keeps identical temperature.Therefore in fact got rid of the stress in the material of pusher jack 2, described stress may occur after the big temperature difference of appearance.They can allow less stress in no problem ground, because can not disturb pusher jack 2 orientation each other and their portrait orientation.
In addition, highly Rong Xie polyamide has small quality, so supporter 3 finally has small quality too.For the moving element of knitting machine, low quality is always wished.
