Technical field
The utility model relates to die industry technical field, particularly a kind of locomotive earthing block drawing mould.
Background technology
Locomotive earthing block is mainly made up of aluminium core and the copper layer that is coated on aluminium core outside, the main work flow of this locomotive earthing block is rolling and drawing procedure, in drawing procedure, the structure of conventional copper bar drawing mould is made up of lubrication belt and sizing area two parts, lubrication belt is the horn mouth with certain taper, sizing area is the Main Deformation of material, and its cross section is certain taper shape.Such structure makes copper bar drawing mould carry out drawing copper clad aluminum wire and has following problem: copper clad aluminum wire is larger at the heat of drawing deformation, the lubricating oil of lubrication belt is difficult to reach effect lubricated, cooling, cause between copper clad aluminum wire and mould and produce frictional heating, very easily damage material surface.Therefore be necessary the structure of present drawing mould to carry out technological innovation further.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of locomotive earthing block drawing mould simple in structure, reasonable in design, easy to use is provided.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of locomotive earthing block drawing mould described in the utility model, comprise die ontology, the nib of die ontology is provided with lubricated district, workspace and goes out cone mouth, and the inwall in described lubricated district is axially provided with some annular lubrication belts, the cross section semicircular in shape shape of lubrication belt along nib; Described workspace is made up of rectangle region and taper district, and taper district is arranged on out between cone mouth and rectangle region, and rectangle region is identical with the axial length in taper district, and the taper ratio in taper district goes out extremely when young 30 degree of tapering of cone mouth.
Further, the inwall of described rectangle region is axially provided with some chip areas along nib, and described die ontology is provided with some the chip removal flutes that run through die ontology, and chip removal flute one end is connected with oil inlet pipe, and the chip removal flute other end is connected with chip discharging tube; Chip area is connected and communicates with chip removal flute.
Further, the angle between described chip area and chip removal flute is less than 90 degree.
Further, the upper parallactic angle of entering bits end of described chip area is circular shape setting.
Adopt after said structure, the utility model beneficial effect is: a kind of locomotive earthing block drawing mould described in the utility model, comprise die ontology, the nib of die ontology is provided with lubricated district, workspace and goes out cone mouth, the inwall in described lubricated district is axially provided with some annular lubrication belts, the cross section semicircular in shape shape of lubrication belt along nib; Described workspace is made up of rectangle region and taper district, and taper district is arranged on out between cone mouth and rectangle region, and rectangle region is identical with the axial length in taper district, and the taper ratio in taper district goes out extremely when young 30 degree of tapering of cone mouth.In the time using the utility model, by workspace being arranged to rectangle region and taper district, by be provided with the lubrication belt of semi-circular shape in lubricated district, the lubricant effect and the cooling ability that greatly improve drawing mould, greatly reduced the problem of damaging material surface because producing frictional heating between copper clad aluminum wire and mould.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the enlarged drawing at A position in Fig. 1;
Description of reference numerals:
