Technical field
The present invention relates to a kind of wire-drawing die, relate in particular to a kind of the guarantee high ratio of briquetting of wire rod and high-quality Novel wire drawing die, belong to the wire-drawing die technical field.
Background technology
Wire drawing die is the instrument that carries out metal wire (rod) material extending.There is a nib at the center of wire drawing die, and the shape of nib can be circular, square or octagonal.Its size decreases when metal is hauled through nib, even shape all can change.Existing wire drawing die mainly is comprised of steel bushing and core rod, and steel bushing is generally stainless steel, and core rod can be selected the materials such as carbide alloy, steel alloy, natural diamond or artificial diamond, and both realize permanent connection by interference fit or welding.
Owing to having larger friction and vibration in the wire drawing production process, therefore, the core rod temperature of wire drawing die can be very high, directly affected the drawing quality of wire drawing die and wire rod; Simultaneously, larger frictional force also easily causes the situation of wire rod fracture in drawing process, affects the ratio of briquetting of wire rod.For this reason, in the wire rod drawing process, essential enforcement is lubricated and the cooling operation.In existing technology, the lubricated and heat sink of wire rod all is arranged on the outside of wire drawing die, and the Cooling and Lubricator effect of wire rod is comparatively general, and the forming temperature of wire rod and frictional resistance are still larger, have directly affected drawing quality and the ratio of briquetting of wire rod.
Summary of the invention
For the demand, the invention provides a kind of Novel wire drawing die, this wire-drawing die structural design uniqueness, wire rod is lubricated fully in Working mould, has effectively reduced frictional force to wire quality and the impact in core rod life-span; Simultaneously, the correction mould has carried out sufficient cooling in the process of revising wire size to wire rod, has effectively controlled the forming temperature of wire rod, has improved the ratio of briquetting of wire rod.
The present invention is a kind of Novel wire drawing die, this wire-drawing die comprises Working mould and correction mould, and described Working mould and correction mould are arranged in same die sleeve, and both axis in line, on described Working mould, circulating oil system is set, on described correction mould, circulating cooling system is set.
In a preferred embodiment of the present invention, described Working mould and correction mould form by steel bushing and core rod, and the active length of Working mould core rod is about 4-4.5cm, and the active length of revising the mould core rod is about 3-3.5cm.
In a preferred embodiment of the present invention, the steel bushing lead-in wire terminal of described Working mould is offered the lubricating fluid guide hole, and its aperture is about 5mm.
In a preferred embodiment of the present invention, the steel bushing lead-in wire terminal of described correction mould is offered the cooling fluid guide hole, and its aperture is about 4mm.
In a preferred embodiment of the present invention, the lower left quarter of described Working mould and correction mould arranges respectively lubricating fluid holding tank and cooling fluid holding tank.
In a preferred embodiment of the present invention, the power of the circulating cooling system that the circulating oil system that described Working mould is installed and correction mould are installed provides by Mini gear pump, and the motor power of gear pump is 0.4kw, and theoretical displacement is 2.5ml/r.
In a preferred embodiment of the present invention, described Working mould and the mounting distance of revising between mould are controlled at the 15cm left and right.
The present invention has disclosed a kind of Novel wire drawing die, this wire-drawing die is sectional die, its Working mould has good lubricating ability, can effectively reduce frictional force to wire quality and the impact in core rod life-span, and revise mould, good cooling capacity is arranged, can effectively control the forming temperature of wire rod, improve the ratio of briquetting of wire rod; Simultaneously, the lubricated and refrigerating function of mould is controlled by hydraulic means, and automaticity is high, and function realizes convenient, dependable performance.
The accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation:
Fig. 1 is the structural representation of embodiment of the present invention Novel wire drawing die;
In accompanying drawing, the mark of each parts is as follows: 1, Working mould, 2, revise mould, 3, the lubricating fluid guide hole, 4, the cooling fluid guide hole, 5, the lubricating fluid holding tank, 6, the cooling fluid holding tank, 7, stainless steel tube.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
