Description
[technical field]
The present invention relates to a kind of yarn mouth and processing method that is used for sending on the flat machine yarn part.
[background technology]
The thread-carrier that uses on the present flat machine (being commonly called as " yarn mouth ").Its preparation method various ways has hot investment casting moulding (Fig. 7); Several different methods (Fig. 8) such as useful textile ceramic sintering making, but all be difficult to accomplish institute's desired shapes and dimensional requirement in the design.Quality influence to knit product is very big.
Flat machine in process of production, head is to do reciprocating action to drive the braiding that knitting needle is realized the cloth sheet on needle-bar, the line outlet of yarn mouth must both sides symmetries (Fig. 9), can make knitting needle in round braiding process, with identical condition of work, form the identical circle of knitting, weave beautiful cloth sheet.But this yarn mouth difficulty on making is very big.The bobbin case of circular arc and tiny deep hole, mechanical processing difficulty is bigger, and geometry and dimensional accuracy all are difficult to guarantee.
In plating-knitted technology, the quality of above-mentioned yarn mouth plays considerable effect.Directly have influence on the quality of product.The two yarn mouths that use in plating-knitted technology require to wear simultaneously two different yarns on the technology, and at the line that the port of export of yarn also will hook with knitting needle, form specific angle, can realize the requirement of technology smoothly.
The yarn mouth in use rubs with yarn is long-term, requires the inwall in yarn mouth hole and wire inlet-outlet all certain smoothness will be arranged, to be reduced in the braiding process frictional force of yarn and yarn mouth mouth.But the deep hole of existing yarn mouth and the polishing of arcuate socket are very difficult, all a period of time of break-in in use, just can reach result of use.
At the problems referred to above, the inventor has designed this patent, with the effective the problems referred to above of having improved.
[summary of the invention]
It is low to the invention provides a kind of difficulty of processing, low cost of manufacture, and accuracy of manufacture height, polishing is easy to the yarn mouth, and the manufacture method of above-mentioned yarn mouth is provided simultaneously.
The present invention is achieved in that a kind of yarn mouth that is used on the flat machine, the integrated punching moulding, include fixed part and be connected the outlet portion of its lower end, on fixed part, be provided with installing hole, in outlet portion, be provided with transport line hole and Top Leading-out Hole, the protuberance that the front surface of the oriented outlet of punching press portion protrudes between transport line hole and the Top Leading-out Hole, the back of this protuberance is surrounded by the transport line passage that communicates with transport line hole and Top Leading-out Hole, under the above protuberance of outlet portion, also be provided with the outlet flanging, on the outlet flanging, be provided with the following wire hole relative with the transport line passage.
Described Top Leading-out Hole is symmetrical bar hole, each side is provided with a screens in the upper end of wire hole.
Described wire hole down is a circular hole.
Also punching press has two spacing flangings above transport line hole in the outlet portion, has spacing hole on spacing flanging.
Described two spacing flangings become upper and lower arrangement setting in outlet portion, one of them spacing flanging is to the front surface bending of outlet portion, and another spacing flanging is to the bending of the rear surface of outlet portion.
The method of yarn mouth is stated in processing, and it comprises the steps:
(a), blanking forming: the blanking in mould of shape on request forms sheet metal;
(b), the punching out endoporus: punching out installing hole on the fixed part of sheet metal, at the outlet portion punching out transport line hole and the Top Leading-out Hole of sheet metal;
(c), beat shallow bore hole: be equipped with wire hole down at the termination sheet that is positioned on the sheet metal below the Top Leading-out Hole;
(d), punching press protuberance: the transport line hole on the sheet metal and the part between the Top Leading-out Hole to the punching press of sheet metal front surface, are formed the protuberance that protrudes, and the back of this protuberance is surrounded by the transport line passage that communicates with transport line hole and Top Leading-out Hole;
(e), bending and molding: with the termination sheet along Top Leading-out Hole to the bending of sheet metal front surface, form the yarn mouth.
When the punching out endoporus, punching out simultaneously has two tandem arcuate sockets.
When beating shallow bore hole, two sides that arcuate socket surrounded on sheet metal respectively are equipped with a spacing hole simultaneously.
When bending and molding, the front surface with an arcuate socket one side direction sheet metal bends simultaneously, with the rear surface bending of another arcuate socket one side direction sheet metal.
Before bending and molding, burr are carried out on the surface of sheet metal handle.
Compared with prior art, advantage of the present invention is as follows:
1, utilizes the making of current panel beating formation mould punching press, avoided the many contradiction in the original manufacture craft, original tiny deep hole is designed to shallow bore hole, change original closed half arcuate socket of arcuate socket, reduced the difficulty on the manufacture craft for opening wide.
2, change the geometry and the manufacture craft of original shuttle mouth mouth, can realize simultaneously the geometry and the dimensional accuracy that design, improved the precision of product.
3, using on the material, also only needing steel disc to manufacture, meeting the requirements of hardness through heat treatment and get final product, low cost of manufacture.
4, before bending and molding, available very simple method is polished circular hole and arc part, just can promote smoothness, reaches the craft precision requirement
5, prolonged the service life of product.
