Abstract
The utility model provides a heddle eye for steel wire heddles, which is characterized in that the inner side of the heddle eye is provided with a smooth circular arc face, the outer side is provided with a groove, and produced pieces don't have interfaces. The utility model can be combined with wire heddles firmly and is not easy to fall off. When moving in the heddle eye, warp yarn is not easy to generate yarn break.
Description
The utility model relates to a kind of improved steel wire heald harness eye, is applicable to that textile industry is weaved to use steel wire heald.
Existing steel wire heald has dull and stereotyped harness eye and interface harness eye with harness eye, and purpose is to weave in the operation in textile industry, and warp thread has stress preferably when moving in harness eye.Dull and stereotyped harness eye is to use the band of desired thickness through the punch press punch forming; The interface harness eye is that bending was welded after the flat filament with required sectional dimension was cut into certain-length.Therefore, jagged on the inwall of many dull and stereotyped harness eyes, the interface of interface harness eye has slit and/or dislocation.When warp thread moves, be easy to generate broken yarn in harness eye, also, cause the many and loom of fabric defects to stop platform rate height because these two kinds of harness eyes and steel wire heald in conjunction with insecure, come off when weaving operation easily.
The purpose of this utility model is to avoid above-mentioned weak point of the prior art and a kind of inboard is provided is the steel wire heald harness eye that smooth arc surface, the outside has groove, no interface.
The purpose of this utility model can reach by following measure: after annealed processing is made its mild-carbon steel strip leveling that has softened, there is the stamping-out flange moulding multi-station progressive die punching out of the guiding crossbearer that rolls to become required form through a punch press and a subband, carry out carburizing and quenching then, make harness eye reach HRC52~58 towards part hardness, again harness eye is placed in vibrating burnisher or the drum polishing machine towards part and abrasive material and polishing fluid, carry out polishing, place electroplate liquid zinc-plated towards part harness eye at last, promptly get harness eye described in the utility model.
Harness eye of the present utility model can be made into three kinds of circles, ellipse, Long Circle.
The drawing of accompanying drawing is described as follows:
Fig. 1 is the cross-sectional view of harness eye described in the utility model.
Fig. 2, Fig. 3, Fig. 4 are three kinds of shapes of the related product of the utility model.
The utility model is described in further detail below in conjunction with embodiment:
To realize that Fig. 2 product is an example.The mild-carbon steel strip that 0.25mm is thick places well formula annealing furnace, under 670~680 ℃ of temperature, be incubated 10 hours, make it softening, cut into the 9mm wide strip then, the stamping-out flange moulding multi-station progressive die that the guiding crossbearer that rolls is arranged by 10 tons of punch presses and a subband behind the leveling, go out circular hole at first station, second station is to cooperate with pilot pin with the circular hole that first station is gone out to carry out the precision guiding, the 3rd station is that the circular hole that will go out carries out hole flanging, and the 4th station is the flange moulding, and the 5th station is a blanking, the 6th station is to be that locating hole leads with the material-dropping hole, produces in proper order continuously with this.Harness eye is placed carburizer towards part, under 920~940 ℃ of temperature, be incubated 2 hours and carry out Carburization Treatment, quench then, tempering, make harness eye reach HRC52~58 towards part hardness, harness eye is placed on towards part and abrasive material and polishing fluid carries out polishing in the vibrating burnisher again, place electroplate liquid zinc-plated towards part harness eye at last, promptly obtaining circular inboard is smooth arc surface, and the outside has groove, the steel wire heald harness eye of no interface.
For Fig. 3 or harness eye shown in Figure 4, in mould, be achieved in that behind the 5th station blanking circle is pushed back billot towards part, at the 6th station during when the punch press down stroke, again circle is released towards part, two shaping pieces that utilize two wedges on the patrix to promote on the counterdie are shaped to Fig. 3 or harness eye shown in Figure 4 to circular harness eye, the 7th station also is to be that locating hole leads with the material-dropping hole, produces continuously.
The utility model has following advantage than existing harness eye:
1, harness eye is inboard is smooth arc surface, no burr, no interface, the warp thread not broken yarn that moves therein.
2, the outside has groove, energy and securely combination of steel wire heald, difficult drop-off.
Claims (1)
- A kind of steel wire heald harness eye is characterized in that the inboard smooth arc surface that is, the outside has groove, and product does not have interface.
