Abstract
The utility model discloses a continuous extrusion silver-copper strip billet die which comprises dies, wherein pads are arranged on the dies; a first horn-shaped channel is formed in the pads. According to the continuous extrusion silver-copper strip billet die, the problem of non-uniform flowing speed caused in a continuous extrusion silver-copper strip billet forming process is solved; the quality of products is improved, and the service life of the die is prolonged.
Description
Technical field
The utility model relates to a kind of continuously extruded silver-bearing copper made-up belt mould, belongs to technical field of nonferrous metal processing.
Background technology
Silver-bearing copper has good electric conductivity, mobility and wellability, mechanical performance, wearability and resistance fusion welding preferably.The silver-bearing copper band is widely used in the Aero-Space cable shield, automobile packing ring and tank radiating plate, and printing cylinder, used for printed circuit foil, the relay on electrical equipment industry, engine commutator, connector, electrode is on the products such as brush.
Adopt continuously extruded cold-rolling practice to produce the high precision silver copper alloy plate strip, belong at home pioneering, production cost is low, precision is high, performance is good, constant product quality, has obvious competitive advantage on price and performance.
Add the silver element of certain content in copper, can cause the hardness of copper material to raise, during continuous extrusion production silver-bearing copper made-up belt, the silver-bearing copper made-up belt is difficult to be full of fully shaping, easily cracks, lacks the defectives such as material, can't large batch ofly produce.
The content of invention
The purpose of this utility model is to provide a kind of continuously extruded silver-bearing copper made-up belt mould, has solved the inhomogeneous problem of flowing velocity that occurs in continuously extruded silver-bearing copper made-up belt shaping, has improved product quality and mold use life-span.
In order to achieve the above object, the technical solution of the utility model is:
A kind of continuously extruded silver-bearing copper made-up belt mould comprises mould; On described mould, pad is installed; Offer the first horn-like passage on described pad.
The upper end of described mould offers the second horn-like passage; Horn-like passage is small-bore is connected on the heavy caliber of described the second horn-like passage and pad first.
The described first horn-like passage is preferably the horn-like passage that cross section is dumbbell shape; The described second horn-like passage is preferably the horn-like passage that cross section is rectangle.
The beneficial effects of the utility model are: the utility model provides a kind of continuously extruded silver-bearing copper made-up belt mould, be difficult to be full of fully shaping for continuously extruded silver-bearing copper made-up belt, easily crack, lack the defectives such as material, solve by optimizing mould and increasing crush stroke.Adopt unique mould and gasket design scheme, increased squeezing passage, solved the inhomogeneous problem of flowing velocity that occurs in continuously extruded silver-bearing copper made-up belt shaping, improved product quality and mold use life-span.
Description of drawings
Fig. 1 is the vertical section figure of the continuously extruded silver-bearing copper made-up belt of the utility model mould;
Fig. 2 is the cross-sectional view of the first horn-like passage of the continuously extruded silver-bearing copper made-up belt of the utility model mould pad;
Fig. 3 is the cross-sectional view of the second horn-like passage of the continuously extruded silver-bearing copper made-up belt of the utility model mould.
The specific embodiment
Below in conjunction with accompanying drawing, a nearly step being done in enforcement of the present utility model describes in detail.
Embodiment 1
By Fig. 1,2,3 as can be known, a kind of continuously extruded silver-bearing copper made-up belt mould comprises mould 1; On described mould 1, pad 2 is installed; Offer the first horn-like passage 3 on described pad 2.The upper end of described mould 1 offers the second horn-like passage 4; The first horn-like small-bore being connected of passage 3 on the heavy caliber of the described second horn-like passage 4 and pad 2.The described first horn-like passage 3 is the horn-like passage of dumbbell shape for cross section; The horn-like passage that the described second horn-like passage 4 is rectangle for cross section.
As shown in Figure 1, the silver-bearing copper blank passes the first horn-like passage 3 of pad 2 under pressure, has increased squeezing passage by pad, then is extruded the second horn-like passage 4 by mould 1, and the copper stock can be full of shaping fully mould 1 is interior.
The present embodiment provides a kind of continuously extruded silver-bearing copper made-up belt mould, is difficult to be full of fully shaping for continuously extruded silver-bearing copper made-up belt, easily cracks, lacks the defectives such as material, solves by optimizing mould and increasing crush stroke.Adopt unique mould and gasket design scheme, increased squeezing passage, solved the inhomogeneous problem of flowing velocity that occurs in continuously extruded silver-bearing copper made-up belt shaping, improved product quality and mold use life-span.
