Abstract

The utility model relates to a dry type wiredrawing machine comprising a pay-off device (1), a winding device (2) and a plurality of wiredrawing machine sets (3) arranged between the pay-off device (1) and the winding device (2), wherein each wiredrawing machine set (3) comprises a winding drum (4) and a wiredrawing die (5) positioned in front of the winding drum (4); a pay-off wheel (6) is arranged between two adjacent wiredrawing machine sets (3); and the wiredrawing die (5) comprises a front wiredrawing die (7) and a rear wiredrawing die (8) arranged in the front and the rear parts. According to the dry type wiredrawing machine, as the traditional single-die drawing is replaced with double-die drawing, the production efficiency of steel wire drawing can be kept or improved; as a drawing technology with multi-stage small compression ratio is utilized, the cooling and lubrication of a steel wire in each stage in a drawing process are guaranteed, the plastic deformation of the steel wire is facilitated, the steel wire is smoothly drawn, the broken rate of the steel wire drawing can be reduced, and production of a high-performance finished product steel wire is facilitated, thus the production purpose of high efficiency and high quality is achieved.

Description

The dry wire drawing device

Technical field

The utility model relates to a kind of dry wire drawing device, belongs to the steel wire drawing technical field.

Background technology

Steel wire drawing is the plasticity of utilizing metal, also makes under external force flow of metal by wire-drawing die, thereby obtains a kind of stress metal processing method of required shape, size, machinery and physical property.In the drawing process, wire drawing die and drawing reel drum that steel wire reduces successively by a plurality of sectional areas continuously, the corresponding reel of a general wire drawing die, under the tractive force effect of reel, steel wire is compressed by cross-sectional area behind the wire-drawing die, through after the compression of multi-pass, finally obtain the shape and size that designing institute needs.

Metallic article enterprise in the steel wire drawing process, adopts the method for raising equipment drawing speed and increase compression ratio to enhance productivity for realizing the maximization of productivity effect mostly.Since the steel wire of traditional dry wire drawing device between adjacent two reels during drawing the wire drawing die of process be single mode, high-speed, large compression ratio technique that steel wire drawing adopts can make a material rate of deformation accelerate, and produces large calorimetric, along with wire temperature raises, lubricating layer is destroyed, cause lubrication failure, cool off bad, the further wearing and tearing between aggravation steel wire and the mould, make that steel wire cracks, scratch, finally cause fracture of wire, mould consumption to increase, also have influence on the final performance of steel wire.

Along with the development of society with technology, the purposes of steel wire and goods thereof is more and more wider, therefore how performance to cold drawn wire has also proposed more and more higher requirement, can not only guarantee efficient production efficiency but also can produce high performance finished product steel wire to be exactly a technical barrier in the urgent need to address.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of realization production high efficiency, high-quality dry wire drawing device are provided.

The purpose of this utility model is achieved in that

A kind of dry wire drawing device, it comprise actinobacillus device, wrap-up and be arranged at actinobacillus device and wrap-up between a plurality of wire drawing units, the wire-drawing die that described wire drawing unit comprises reel and is positioned at reel the place ahead, be provided with actinobacillus wheel between described adjacent two wire drawing units, also be provided with actinobacillus wheel between last wire drawing unit and the wrap-up, a wire-drawing die also is set, wire drawing front mould and the wire drawing rear mold of arranging before and after described wire-drawing die comprises before the described wrap-up.

Compared with prior art, the beneficial effects of the utility model are:

The utility model forms the bimodulus drawing because wire-drawing die comprises wire drawing front mould and the wire drawing rear mold of lateral arrangement.Adopt the bimodulus drawing to replace traditional single mode drawing, can keep or improve the production efficiency of steel wire drawing, adopt simultaneously the drawing technique of the little compression ratio of multi-pass, guaranteed the cooling and lubrication of steel wire each passage in drawing process, be conducive to the plastic deformation of steel wire, thereby realize the smooth drawing of steel wire, both can reduce the wire broken rate of steel wire drawing, also be conducive to produce high performance finished product steel wire.High efficiency, high-quality productive target have been realized.

The specific embodiment

Referring to Fig. 1 and Fig. 2, a kind of dry wire drawing device that the utility model relates to, it comprises actinobacillus device 1, wrap-up 2 and be arranged at actinobacillus device 1 and wrap-up 2 between a plurality of wire drawing units 3, the wire-drawing die 5 that described wire drawing unit 3 comprises reel 4 and is positioned at reel 4 the place aheads, be provided with actinobacillus wheel 6 between described adjacent two wire drawing units 3, also be provided with actinobacillus wheel 6 between last wire drawing unit 3 and the wrap-up 2, a wire-drawing die 5 also is set, wire drawing front mould 7 and the wire drawing rear mold 8 of arranging before and after described wire-drawing die 5 comprises before the described wrap-up 2.

Embodiment: as shown in Figure 1, high-performance spring steel wire 3.0mm is drawn to 1.0mm.The compression ratio of at first setting first and extreme trace is about 15%, and all the other pony-roughing pass Partial shrinkage rates are about 20%, totally 10 passes of drawing; The double mould pressing shrinkage is distributed by unequal principle, and namely in a passage, the aperture of the last mould of bimodulus is 1 ~ 1.5 times of the second mould, and last mould can be born increases lubricated pressure mould or the function of drawing die; A rear mould can be born the function of drawing die or stock mould.The unequal distribution principle of double mould pressing shrinkage is conducive to reduce finished product steel wire residual stress, guarantee the finished product steel wire intensity, reverse, the mechanical property such as extension.

Operation principle:

Steel wire 9 begins to unreel from actinobacillus device 1, then the wire-drawing die 5 from first wire drawing unit 3 enters reel 4, enter next wire drawing unit 3 by actinobacillus wheel 6, and so forth, steel wire 9 is delivered to wrap-up 2 from last wire drawing unit 3 to last wire-drawing die 5.

Because wire drawing front mould 7 and the wire drawing rear mold 8 of arranging before and after wire-drawing die 5 comprises, the Reduction per draft when total draught that wire drawing front mould 7 is connected with wire drawing rear mold 8 is equal to or greater than traditional single mode drawing, the performance requirement different according to the finished product steel wire, wire drawing front mould 7 can be adjusted with the compression ratio that wire drawing rear mold 8 is distributed.

During wire-drawing die 5 drawing, wire drawing front mould 7 can be used as the lubrication pressure mould, also can share the Partial shrinkage rate for wire drawing rear mold 8, has also played simultaneously and has proofreaied and correct the steel wire position, guaranteed that steel wire enters the straight effect of mould; Wire drawing rear mold 8 is mainly born the effect that makes the steel wire distortion, also can play the effect of typing, adjustment mechanical properties of wires.
