Embodiment Construction

[0016] A continuous extrusion device for extended extrusion used to produce extruded products on continuous extrusion equipment, as shown in Figure 1, includes an extrusion wheel and a mold, and the extrusion wheel with grooves in the circumferential direction is rotatably installed on a rotating shaft 8 , there is a stop block 7 on one side of the cavity, a billet feed port is arranged in the middle of the cavity, a mold 2 is installed on the cavity below the feed port, and the width of the groove 10 on the extrusion wheel 9 is H1, the cavity The width dimension of the feed opening 3 on the 1 is H2, and the dimension H2 is obviously increased, so that H2 is greater than the width H1 of the groove 10 of the extrusion wheel 9 plus twice the fillet radius, that is, H2>H1+2R. The length dimension B of the feed opening 3 is greater than 1.6 times the width dimension of the groove 10 . The cross-sectional shape of the feed port 3 of the cavity 1 can be any shape. As shown in Figure...

Abstract

The invention relates to a method for compressing metal. Wherein, in the groove of compressing wheel or at the material inlet of chamber, the blank is extended to be 10mm wider than the groove width of compressing wheel; then feeding the blank into material inlet, to be compressed via mould into needed product. The invention has simple process, to obtain better shape when compressing color metal wire or round rod, and obtain accurate size, to reduce the pressure and temperature of mould. And it can improve the rotation speed of compressing wheel and improve the yield.

Description

Technical field: [0001] The invention relates to an extrusion method and an extrusion device for manufacturing copper and aluminum busbars, ladder rows, flat wires, bars and the like. Background technique: [0002] Continuous extrusion method is used to produce copper, aluminum bus bar, copper, aluminum row, copper, aluminum flat wire, round, square bar, etc. The width of the wheel groove on the extrusion wheel is basically close to the width of the feed port on the cavity. . The geometric shape of the cavity feed port is a rectangular hole with four corners and rounded corners. The length dimension of the feed opening is less than 1.6 times the width dimension of the wheel groove. The shape of the groove of the extrusion wheel is a groove with straight sides on both sides, and there is a transitional arc between the straight side and the outer cylindrical surface of the wheel. [0003] The disadvantages of the cavity with this structure are as follows: when extruding a l...
