The traditional single-mould drawing way is replaced with the double-mould drawing way provided by the utility model, so that the production efficiency for steel wire drawing can be kept or increased; and a multi-pass low-compressibility drawing technology is adopted, so that cooling and lubricating of a steel wire in each pass in the drawing process are ensured, the plastic deformation of the steel wire is ensured, then, the steel wire is successfully drawn, the wire breaking rate in the steel wire drawing process can be reduced, and a finished product steel wire with high performance can be favorably produced. The aim of producing at high efficiency and high quality is achieved.

Description

Wet type water tank wire-drawing frame

Technical field

The utility model relates to a kind of wet type water tank wire-drawing frame, 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 cone pulley that steel wire reduces successively by a plurality of sectional areas continuously, the corresponding cone pulley of a general wire drawing die, under the tractive force effect of cone pulley, 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 wet type water tank wire-drawing frame between adjacent two cone pulleys 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 wet type water tank wire-drawing frame are provided.

The purpose of this utility model is achieved in that

A kind of wet type water tank wire-drawing frame, it comprises actinobacillus device, the first cone pulley, mould bases, the second cone pulley, finished product diaphragm capsule and wrap-up from front to back successively, described the first cone pulley, mould bases, the second cone pulley and finished product diaphragm capsule all place in the water tank, be provided with from top to bottom many group wire-drawing dies on the described mould bases, described wire-drawing die and finished product diaphragm capsule include wire drawing front mould and the wire drawing rear mold of lateral arrangement.

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

The utility model forms the bimodulus drawing because wire-drawing die and finished product diaphragm capsule include 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 wet type water tank wire-drawing frame that the utility model relates to, it comprises actinobacillus device 1, the first cone pulley 2, mould bases 3, the second cone pulley 4, finished product diaphragm capsule 5 and wrap-up 6 from front to back successively, described the first cone pulley 2, mould bases 3, the second cone pulley 4 and finished product diaphragm capsule 5 all place in the water tank, be provided with from top to bottom many group wire-drawing dies 7 on the described mould bases 3, described wire-drawing die 7 and finished product diaphragm capsule 5 include wire drawing front mould 8 and the wire drawing rear mold 9 of lateral arrangement.

Embodiment: as shown in Figure 1, zinc-coated wire 3.0mm is drawn to 1.0mm, and total draught is about 88.9%.The compression ratio of 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 compression ratio of wire-drawing die is pressed Principle of Average Allocation, and namely two moulds of first and extreme trace are born respectively the compression ratio about 7.5%, and middle each passage wire-drawing die is born respectively the compression ratio about 10%; The bimodulus drawing is conducive to reduce scratch and the loss of the zinc layer of zinc coat in drawing.

Operation principle:

Steel wire 10 begins to unreel from actinobacillus device 1, then first wire-drawing die 7 to second cone pulleys 4 that pass through on the mould bases 3 from the first cone pulley 2, the second cone pulley behind 2 ~ 4 circles from mould bases 3 belows around to the first cone pulley 2, rear by second wire-drawing die, 7 to second cone pulleys 4 on the mould bases 3 around 2 ~ 4 circles at the first cone pulley 2 again, and so forth, steel wire 10 is delivered to wrap-up 6 by finished product diaphragm capsule 5 again behind last wire-drawing die 7 to second cone pulley 4.

Because wire-drawing die 7 and finished product diaphragm capsule 5 include wire drawing front mould 8 and the wire drawing rear mold 9 of lateral arrangement, the Reduction per draft when total draught that wire drawing front mould 8 is connected with wire drawing rear mold 9 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 8 can be adjusted with the compression ratio that wire drawing rear mold 9 is distributed.

During wire-drawing die 7 drawing, wire drawing front mould 8 can be used as the lubrication pressure mould, also can share the Partial shrinkage rate for wire drawing rear mold 9, 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 9 is mainly born the effect that makes the steel wire distortion, also can play the effect of typing, adjustment mechanical properties of wires.
