Abstract
The invention relates to the technical field of textile machines and particularly relates to a special flat steel heald for weaving carbon fiber. The special flat steel heald is a long and thin stripped sheet made of two stainless steel materials or made by coating chrome on the surface of carbon steel; two ends of the special flat steel heald are sequentially and respectively provided with a heald lug and a recognition hole; the middle of a flat steel heald body is provided with two heald eyes; the flat steel heald body has the total length of 280-482mm, the width of 5.5mm and the thickness of 0.25+/-0.01mm; the heald eyes are elliptical holes with the lengths of 5.5mm, 6.5mm and 8.0mm and the widths of 1.2mm, 1.8mm and 2.5mm. The special flat steel heald is made of the stainless steel materials or made by coating chrome on the surface of carbon steel so as to be corrosion-resistant under a high-temperature and high-humidity environment, free of dazzling gloss on the surface and convenient for computer operation. Due to the additional arrangement of the heald eyes, the weight of the flat steel heald body is reduced, a weaving machine is capable of saving energy and reducing consumption, and the production cost of carbon cloth is reduced.
Description
Technical field
The present invention relates to technical field of textile machine, the special flat metal heald of especially a kind of carbon fiber weaving.
Background technology
Existing biserial flat metal heald, as shown in Figure 1, the elongated strip thin slice that adopts carbon steel to make, two ends are provided with heald end loop 1 from outside to inside successively, gait hole 2 and identifying hole 3, and centre is provided with the poroid harness eye 4 of rectangle.Because the vehicle speed of shuttleless loom is generally 500～800r/min left and right, loom opening frequently make yarn under tension force effect to flat metal heald harness eye reciprocating friction, this has especially caused serious friction in harness eye position to undoubtedly flat metal heald body, causes flat metal heald to use and scraps because of wearing and tearing.Although manufacturers are in the material of flat metal heald, harness eye structure and reduce the aspects such as friction factor and taked a lot of measures and method, but existing flat metal heald also can only maintain and use about 3-6 month in the time weaving common fabric, just need to change, especially during to woven carbon cloths and glass, more cannot use, have a strong impact on shuttleless loom operating efficiency, virtually increase textile mills' production cost.
Summary of the invention
In order to overcome the deficiency that existing biserial flat metal heald service life is short, cost is high, the invention provides the special flat metal heald of a kind of carbon fiber weaving.
The technical solution adopted for the present invention to solve the technical problems is: the special flat metal heald of a kind of carbon fiber weaving, it is the elongated strip thin slice that two stainless steel materials or steel surface chromium plating are made, two ends are respectively equipped with heald end loop 1 and identifying hole 3 successively, the centre of described flat metal heald body is provided with two harness eyes 4, the total length of described flat metal heald body is 280mm～482mm, width is 5.5mm, thickness is 0.25mm ± 0.01mm, described harness eye 4 is that length is 5.5mm, 6.5mm, 8.0mm, width is 1.2mm, 1.8mm, the slotted eye of 2.5mm, 17 ° ± 1 ° of described harness eye position torsional angle, type shape is S type.
The invention has the beneficial effects as follows, the present invention adopts stainless steel material, under the environment of high temperature and high humidity, corrosion-resistant, and through electrochemical deburring processing, surface does not have the gloss of dizzy eye, is convenient to operate the computer.The heald end loop at described flat metal heald two ends and flat metal heald journal offset certain angle.Make harness eye be passed to positive direction, the drawing-in hook of being convenient to drawing-in machine passes through, and is conducive to improve the speed of gaiting.Owing to having increased harness eye, the quality of its flat metal heald own is alleviated, make loom energy-saving and cost-reducing, fabric production cost reduces.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structural representation of existing biserial flat metal heald;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the schematic diagram at harness eye position.
In figure 1, heald end loop, 2, the hole of gaiting, 3, identifying hole, 4, harness eye.
The specific embodiment
If Fig. 1 is structural representation of the present invention, the special flat metal heald of a kind of carbon fiber weaving, it is the elongated strip thin slice that two stainless steel materials or steel surface chromium plating are made, two ends are respectively equipped with heald end loop 1 and identifying hole 3 successively, the centre of described flat metal heald body is provided with two harness eyes 4, the total length of described flat metal heald body is 280mm～482mm, width is 5.5mm, thickness is 0.25mm ± 0.01mm, described harness eye 4 is that length is 5.5mm, 6.5mm, 8.0mm, width is 1.2mm, 1.8mm, the slotted eye of 2.5mm, 17 ° ± 1 ° of described harness eye position torsional angle, type shape is S type.
This flat metal heald is that the Rapier looms that aims at woven carbon cloths (carbon fiber) designs.
Due to carbon fiber, in the time weaving, to sheet, comprehensive harness eye wearing and tearing have water spray behavior greatly and in weaving, therefore its flat metal heald production material must be with manufacturing through heat treated martensitic stain less steel.(hardness 490-550HV) accomplishes the wear-resisting and anticorrosion of product, increases its durability.
This flat metal heald should be 0.25mm ± 0.01mm at the thickness of actual production and use;
It is that safe and reliable under the prerequisite that meets tensile strength, convenient exchange used and extend product service life that this product arranges two harness eyes;
This product harness eye is shaped as 5.5mm × 1.2mm, 6.5mm × 1.8mm, 8.0mm × 2.5mm ellipse, and after being ground, its polishing carries out again the polishing of electrochemical deburring technique, make harness eye Paint Gloss, greatly reduce coefficient of friction, adaptation carbon fiber carries out product high-quality and weaves.
17 ° ± 1 ° of this product harness eye position torsional angle, type shape is S type.As shown in Figure 3, torsional angle urine is arranged in heald, adapts to carbon cloth and weaves.
This is that warp thread does not need the production feature of situation that warping and sizing send by lease reed and embossed pattern carbon cloth designed during according to carbon fiber weaving, so not only more can meet passing through of warp thread, also can increase the density of heald in heald frame, reduce the use amount of heald frame, improve running speed and the production efficiency of loom.
According to the structure difference of flat metal heald, flat metal heald can be divided into single-row flat metal heald and biserial flat metal heald.Can carry out choice for use by the form of the different size of fabric, thread density and loom hatch frame.
The application's biserial enclosed flat metal heald is used in every one side and wears the heald frame of two row (Fig. 2).
Product size:
Combine height degree (between two heald end loops): 280mm, 302mm, 330mm, 482mm
Width × thickness: 5.5 × 0.25mm
Harness eye size: 5.5 × 1.2mm, 6.5mm × 1.8mm, 8.0mm × 2.5mm
The present invention is in the situation that existing flat metal heald physical dimension, material are constant, Zong Shen center increases a harness eye as an alternative again, extend the service life of flat metal heald, guarantee that flat metal heald body extends one times service life under normal circumstances, harness eye hole of Yin Duokai, the quality of its flat metal heald own is alleviated, make loom energy-saving and cost-reducing, fabric production cost reduces.
