Abstract
The utility model discloses an expanding forming device for continuously extruding a large-section copper rod. The expanding forming device comprises a cavity body, wherein the cavity body comprises a cavity body surface plate and a cover plate, the cavity body surface plate and the cover plate are fixedly connected, a joint of the cavity body surface plate and the cover plate is internally provided with an expanding cavity, and the expanding cavity is internally provided with a gasket and a module. The expanding forming device provided by the utility model solves the problem that the flowing speed is not uniform in a continuous extrusion process of the large-section copper rod, the product quality is improved, and the service life of a module is prolonged.
Description
Technical field
The utility model relates to the expansion shaped device of a kind of continuously extruded heavy in section copper rod, belongs to technical field of nonferrous metal processing.
Background technology
Research and the application of continuously extruded technology in copper processing starts from the nineties in last century, by research of technique, successful realization the industrialization productions such as copper strap wire, copper busbar, copper plate/strip, and reached good economic benefit and social benefit.
At present, for large size copper rod Ф 60mm～Ф 120mm, ratio is large, the cross section is large, adopts continuously extruded technology to be difficult to be full of fully shaping, cracks easily, lacks the defectives such as material, coarse grain ring, solves by optimizing modular angle and increasing crush stroke.
Summary of the invention
The purpose of this utility model has been to provide the expansion shaped device of a kind of continuously extruded heavy in section copper rod, has solved the inhomogeneous problem of flowing velocity that occurs in the copper rod shaping of continuously extruded heavy in section, has improved product quality and mold use life-span.
In order to achieve the above object, the technical solution of the utility model is:
The expansion shaped device of a kind of continuously extruded heavy in section copper rod comprises cavity, and described cavity comprises cavity panel and cover plate, and described cavity panel and cover plate be connected, and forms an extended cavity in its junction; Pad and mould are installed in the described extended cavity successively.
Described pad is the multi-tier pad.
Described pad is preferably 3 grades of expansion pads; Described pad is followed successively by the first pad, the second pad and the 3rd pad; Described the first pad is horn-like pad, and the heavy caliber of the first pad loudspeaker links to each other with the 3rd pad by the second pad; Described the 3rd pad links to each other with mould; The charging aperture of the small-bore and cavity panel of described the first pad loudspeaker links to each other.
The beneficial effects of the utility model are: the utility model provides the expansion shaped device of a kind of continuously extruded heavy in section copper rod, adopt die cavity and the die design schemes of unique multi-tier distortion, increased squeezing passage, solve the inhomogeneous problem of flowing velocity that occurs in the continuously extruded shaping of large ratio, improved product quality and mold use life-span.For large size copper rod Ф 60mm～Ф 120mm, ratio is large, the cross section is large, adopts continuously extruded technology to be difficult to be full of fully shaping, cracks easily, lacks the defectives such as material, coarse grain ring, solves by optimizing modular angle and increasing crush stroke.Adopt die cavity and the Design of Dies of multi-tier distortion, increase substantially the sectional area of copper rod, solved large ratio and a heavy in section expressing technique difficult problem, but production specification is Ф 120mm copper rod.
Description of drawings
Fig. 1 is the vertical section figure of the expansion moulding apparatus structure of the continuously extruded heavy in section of the utility model copper rod.
The specific embodiment
Below in conjunction with accompanying drawing a nearly step being done in enforcement of the present utility model describes in detail.
As shown in Figure 1, the expansion shaped device of a kind of continuously extruded heavy in section copper rod comprises cavity, and described cavity comprises cavity panel 8 and cover plate 5, and described cavity panel 8 is connected with cover plate 5, and forms an extended cavity 2 in its junction; Pad and mould 4 are installed in the described extended cavity 2 successively.Described pad is horn-like 3 grades of expansion pads; Described pad is followed successively by the first pad 3, the second pad 6 and the 3rd pad 7; Described the first pad 3 is horn-like pad, and the heavy caliber of the first pad 3 loudspeaker links to each other with the 3rd pad 7 by the second pad 6; Described the 3rd pad 7 links to each other with mould 4; The charging aperture 1 of the small-bore and cavity panel 8 of described the first pad 3 loudspeaker links to each other.
As shown in Figure 1, the copper stock after extruding is pressed into charging aperture 41, under pressure, passes the first pad 3, the second pad 6 and the 3rd pad 7, is pressed into mould again, has increased squeezing passage by pad, and the copper stock can be full of shaping fully.
The utility model provides the expansion shaped device of a kind of continuously extruded heavy in section copper rod, adopt die cavity and the die design schemes of unique multi-tier distortion, increased squeezing passage, solve the inhomogeneous problem of flowing velocity that occurs in the continuously extruded shaping of large ratio, improved product quality and mold use life-span.For large size copper rod Ф 60mm～Ф 120mm, ratio is large, the cross section is large, adopts continuously extruded technology to be difficult to be full of fully shaping, cracks easily, lacks the defectives such as material, coarse grain ring, solves by optimizing modular angle and increasing crush stroke.Adopt die cavity and the Design of Dies of multi-tier distortion, increase substantially the sectional area of copper rod, solved large ratio and a heavy in section expressing technique difficult problem, but production specification is Ф 120mm copper rod.
