Abstract

The utility model provides a needle bed with embedded needle track and grating type tooth, which comprises a needle plate, a plurality of large embedded pieces, three kinds of small embedded pieces having the same number as the large embedded pieces, extra-thick steel wires, a plurality of thick steel wires and two fine steel wires. A plurality of shallow slots is arranged on the needle plate surface. The lower part of the large embedded piece is embedded in the shallow slot and is fixedly bonded. Meanwhile, the mid-upper part of the large embedded piece is connected with the thick steel wire through interpenetration. The front end of the large embedded piece is positioned by the extra-thick steel wire and thus the needle bed with embedded needle track is formed. The front end in each shallow slot of the needle plate surface is orderly embedded with the three kinds of small embedded pieces and is connected with the extra-thick steel wire through interpenetration; therefore, the grating type tooth is formed. The fine wires are together connected with small embedded pieces through interpenetration and formed port wires. The utility model not only satisfies the requirement of hardness of the needle track, but also makes the operation simple, which improves the yield. Meanwhile, the utility model makes the operation of the port wires simple and reduces the manufacturing cost. The needle bed with embedded needle track and grating type tooth is easy to be repaired, and avoids the whole needle bed discarded as useless once the local parts are damaged, which improves the service life of the needle bed.

Description

Needle-bar with inserted needle track and edge palisade tooth

Technical field

The utility model relates to a kind of needle-bar of weft machine, and especially relating to a kind of needle track and be inserted, tooth hole thread also is inserted needle-bar.

Background technology

The needle-bar of weft machine is provided with many needle tracks, and eedle pumps in needle track.Traditional straight-bar machines is on common needle plate, directly sets out needle track one by one with milling machine.Soft for solving needle track, easily curved, easily broken and this technical problem that needle plate that cause damages of needle track behind the striker, needle plate is many will heat-treat, but that the heat treatment rear faller is out of shape is very big, causes the manufacturing technique complexity, and yield rate is lower.

In addition, the palisade tooth and the draught animals line (hereinafter to be referred as tooth hole thread) that are positioned at the needle-bar front end then are the key links that influences fabric quality, and traditional tooth hole thread also is directly to be processed by milling cutter, and after some local damage, needle plate is also scrapped thereupon, causes bigger waste.

Summary of the invention

The purpose of this utility model is to provide a kind of needle-bar with inserted needle track and edge palisade tooth at above-mentioned technological deficiency.It is on the basis of traditional process technology, has carried out bold innovation and improvement.Novel needle-bar forms the big empiecement that needle track changes over the back hardening of quenching by direct groove milling and directly is embedded in the shallow slot of offering on the needle plate, make two adjacent big empiecements form needle track, both satisfied requirement, and made processing become simple again, improved yield rate needle track hardness.Also adopted mosaic combined tooth hole thread simultaneously, be convenient to change, can avoid because of the whole wasting phenomenon of scrapping of local damage.

The purpose of this utility model is to realize by following technical solution.Design a kind of needle-bar with inserted needle track and edge palisade tooth, it comprises: needle plate, and several big empiecements are with three kinds of little empiecements of the same quantity of big empiecement, a Gent thick wire, some thick wires and two finer wires; Described needle plate sets out a plurality of shallow slots on the surface, and the bottom of described big empiecement is embedded in the shallow slot and is adhesively fixed, and the middle and upper part of simultaneously big empiecement is interted with described thick wire and connected, and the front end of big empiecement is located by extra thick steel wire, forms inserted needle track with this; Front end in each shallow slot of described needle plate surface is inlaid with three kinds of little empiecements successively, and connects with described thick wire is interspersed, forms edge palisade tooth with this; Described finer wire together interts and connects little empiecement, and forms draught animals line.

Needle-bar with inserted needle track and edge palisade tooth of the present utility model has the following advantages compared with prior art:

1, the needle track of novel needle-bar is that big steel disc with the back hardening of quenching directly is embedded in the shallow slot of offering on the needle plate, and interts with thick wire and to form.Two adjacent big steel discs have been formed needle track, have both satisfied the requirement to needle track hardness, make processing become simple again, have improved yield rate.

2, the palisade tooth of novel needle-bar is that, three kind little empiecements stamping forming with high-strength steel strip are inlayed combination and interted with thick wire and form, and draught animals line together interts little empiecement with finer wire and forms.Make tooth hole thread processing become simple, reduced manufacturing cost.

In case 3, novel needle-bar local damage can renewal part, is convenient to maintenance maintenance, avoids integral body to scrap, and has improved the service life of needle-bar, has guaranteed the quality of fabric, and is economical and practical.

The specific embodiment

Below in conjunction with drawings and Examples, further specify the utility model.

Fig. 1 is the cutaway view of cutting open along a certain needle track on the needle-bar, and it illustrates the structure of the utility model needle-bar.With reference to Fig. 1, structure with needle-bar of inserted needle track and edge palisade tooth of the present utility model is: set out a plurality of shallow slots on needle plate 1 surface, the bottom of each big empiecement 2 is embedded in the shallow slot and is adhesively fixed, the middle and upper part of simultaneously big empiecement 2 is interted with thick wire 3 and is connected, the front end of big empiecement 2 forms inserted needle track by extra thick steel wire 4 location with this; Be arranged in order one group of formation with three kinds little empiecements 5,9,6 of big empiecement 2 same quantity, be that little empiecement 9 placed in the middle, little empiecements 5, little empiecement 6 are in both sides, front end in needle plate 1 each shallow slot is inlaid with one group of so little empiecement, about by the groove width of needle plate 1 location, up and down by thick wire 3 location, and, form edge palisade tooth with this with described 3 interspersed connections of thick wire, be convenient to the fabric lopping, move back circle; With reference to Fig. 2, finer wire the 7, the 8th has the quite smooth again steel wire of certain degree of hardness, and both together intert and connect little empiecement 9, and form draught animals line.With reference to Fig. 4, Fig. 5 and Fig. 6, described little empiecement the 9,5, the 6th, the hilt shape is equipped with above and interts the through hole of thick wire 3, offers in addition on the little empiecement 9 to intert the hardy hole of finer wire 7,8.The shape of described big empiecement 2 as shown in Figure 3.

In the such scheme, described thick wire 3 can but be not limited to adopt 6, be design principle can fix big empiecement 2 and negligible amounts.

In the such scheme, the steel disc that hardness improves after the described big empiecement 2 employing Quenching Treatment.

In the such scheme, described little empiecement 5, little empiecement 9, little empiecement 6 adopt high-strength steel strip, make through punch forming processing.

In case needle-bar tooth mouth of the present utility model damages, and can at will change, and has overcome the defective that needle-bar integral body is scrapped, and has reduced manufacturing cost, has improved the service life of needle-bar, has guaranteed the quality of fabric.
