The drawing mould core structure for drawing the steel cord at high speed is relatively high in drawing speed, relatively long in service life and reasonable in structure.
Description
Technical field
The utility model relates to a kind of high speed drawing steel cord wire-drawing mold core structure.
Background technology
Wire drawing die is a kind of very important easy consumption mould of various metal wire rod manufacturers (as wire ﹠ cable factory, wire works, welding rod welding wire factory etc.) drawn wire.The scope of application of wire drawing die is very extensive, is mainly used in drawing bar, wire rod, silk material, the difficult processing object of tubing isoline type, is applicable to the drawing processing of metal such as iron and steel, copper, tungsten, molybdenum and alloy material.Because the cost of wire drawing die accounts for more than 1/2 of wire drawing expense, therefore, how reducing the wire drawing die cost, improving its service life is the problem that the metal wire rod production unit presses for solution.
The structure of wire-drawing mold core can be divided into " inlet region, lubricated district, workspace, sizing area, outlet area " five intervals by job specification.The internal diameter profile of wire drawing die is very important, and it is determining the pulling force that compressed wire is required, and influences the residual stress in the wire rod after the drawing.The effect in each district of core rod is respectively: the inlet region makes things convenient for threading and prevents that steel wire from abrading wire drawing die from Way in; Lubricated district makes steel wire be easy to bring into lubricant by it; The workspace is the major part of nib, and the deformation process of steel wire is here carried out, and is about to original section and is reduced to desired sectional dimension.When drawing taper seat metal, the shared space of the volume of metal is a round platform in the workspace, and this space is called the deformed area.Half-angle of projection α in the workspace (being called the nib half-angle again) is mainly used in the size of determining pulling capacity; The effect of sizing area is to obtain the accurate size by drawn steel wire; Outlet area is to be used to prevent that steel wire from going out the steady and scratch Steel Wire Surface of dipped ring.
Yet the machining accuracy of present finished product mould is not high, and pass designs not science, and unreasonable structure causes its service life low, costs an arm and a leg, and can not satisfy the production demand.
The utility model content
The technical problems to be solved in the utility model provides the high speed drawing steel cord wire-drawing mold core structure that a kind of drawing speed is very fast, service life is higher, rational in infrastructure.
Content of the present utility model is that it comprises the stretching die body, the pass structure of described wire drawing die body is divided into entrance region, lubricated district, workspace, sizing area and outlet area, the height in described lubricated district is the 30-40% of the height of described stretching die body, and the lubricated angle in described lubricated district is the 6-12 degree; The height of described workspace is the 38-48% of the height of described stretching die body, and the height of described workspace is 2.5-3.5 a times of described sizing area height; The height of described sizing area is 0.10-0.20 a times of its diameter; The height of described outlet area is the 1/5-1/3 of the height of described stretching die body.
The beneficial effects of the utility model are when being belonged to by lubricated district by lashing wire, be convenient to bring lubricant into workspace and sizing area, guarantee to be obtained sufficient lubrication, the power of reducing friction and heating phenomenon by the lashing wire genus, be convenient to lubricant and enter the workspace very smoothly, play good lubrication; The workspace is the utility model most important parts, and steel wire is out of shape in this district, obtains needed shape and size, and it must be straight, makes lubricant form fine and close lubricating film in Steel Wire Surface.Sizing area makes by lashing wire and belongs to the further accurate shape and size that obtain to stablize, can make simultaneously core rod avoid wearing and tearing and very fast overproof, thereby improve the service life of stretching die body, its structure is straight, it is absolute cylinder, form a kind of trapezium structure (a stable wear-resisting stage) with the workspace, thereby improve service life of the present utility model; Outlet area prevents to be belonged to by lashing wire and is scratched when pulling out nib, and unlikely the bursting apart of protection the utility model sizing area.
In sum, the utility model is the pass structure of a kind of high speed drawing steel cord wire-drawing mold core of a kind of long service life and simple in structure, dependable performance, can be widely used in high speed metallic article drawing steel cord industry.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
In the drawings, 1 stretching die body, 2 inlet regions, 3 lubricated districts, 4 workspaces, 5 sizing areas, 6 outlet areas.
The specific embodiment
As shown in drawings, the utility model comprises stretching die body 1, the pass structure of described wire drawing die body 1 is divided into entrance region 2, lubricated district 3, workspace 4, sizing area 5 and outlet area 6, the height in described lubricated district 3 is 30-40% of the height of described stretching die body 1, and the lubricated angle in described lubricated district 3 is the 6-12 degree; The height of described workspace 4 is 38-48% of the height of described stretching die body 1, and the height of described workspace 4 is 2.5-3.5 times of described sizing area 5 height; The height of described sizing area 5 is 0.10-0.20 times of its diameter; The height of described outlet area 6 is 1/5-1/3 of the height of described stretching die body 1.
The effect in lubricated district 3 is to be convenient to be brought lubricant into workspace 4 and sizing area 5 by the lashing wire genus by it, its lubricated angle is controlled at the 6-12 degree, be convenient to lubricant and enter the workspace very smoothly, play good lubrication, lubricated district 3 highly is the 30-40% of stretching die body 1 height, guarantees to be belonged to by lashing wire to obtain sufficient lubrication the reduce friction power and the phenomenon of generating heat; The effect of workspace 4 is the utility model most important parts, and steel wire is out of shape in this district, obtains needed shape and size; Its structure is straight, highly is 2.5-3.5 times of sizing area 5 height, so that set up angle of wedge effect, also is the 38-48% of stretching die body 1 height, makes lubricant form fine and close lubricating film in Steel Wire Surface.The effect of sizing area 5 is to make by lashing wire to belong to the further accurate shape and size that obtain to stablize, can make simultaneously nib of the present utility model avoid wearing and tearing and very fast overproof, thereby improve the service life of stretching die body 1, its structure is straight, it is absolute cylinder, the height of sizing area 5 is 0.10-0.20 times of its diameter, forms a kind of trapezium structures (a stable wear-resisting stage) with workspace 4, thereby improves the service life of core rod; The effect of outlet area 6 is to prevent to be belonged to by lashing wire to be scratched when pulling out nib, and protection core rod sizing area 5 unlikely bursting apart, and the height of outlet area 6 is 1/5-1/3 of the height of described stretching die body 1.
Referring to Fig. 1, the utility model is the pass structure of a kind of high speed drawing steel cord wire-drawing mold core of a kind of long service life and simple in structure, dependable performance, can be widely used in high speed metallic article drawing steel cord industry.
