Summary of the invention
The purpose of this utility model is improved for the deficiencies in the prior art exactly, provides a kind of counterdie cantilever beam, assurance forming aluminium section can protected preferably to stablize and accurate in size aluminium alloy hot-extrusion die.
Concrete scheme of the present utility model is: the aluminium alloy hot-extrusion die for the traditional mode of production Superjacent sectional material improves, and it is comprised of deflector and counterdie docking, is provided with charging hole on deflector; Counterdie charging face is provided with the seam chamber, and seam chamber afterbody is provided with die cavity and discharge opening, and the counterdie center is provided with cantilever beam; It is characterized in that: be provided with in the middle of described charging hole over against cantilever beam and with cantilever beam and compress the shunting bridge of arranging, the shunting bridge is divided into upper and lower two tap holes with charging hole, the shunting bridge is provided with over against the horizontal bar section of section bar horizontal bar with over against the open section of section bar open, the cross section of the horizontal bar section of shunting bridge is triangular in shape, top and the deflector one of horizontal bar section of shunting bridge held level with both hands together, bottom and deflector other end interval layout; The bottom section of the open section of shunting bridge is trapezoidal.
The hole face of the inner surrounding of charging hole described in the utility model is the inclined plane shape that expands outwardly, and its tilt angle alpha is 5～10 °.
In order to prevent cantilever beam beat in the process of extruding, the utility model has anti-bias pin-and-hole on the cantilever beam of counterdie, and the shunting bridge is provided with and coordinates the anti-bias pin of installing with anti-bias pin-and-hole.
In order to guarantee that aluminium alloy material stream can converge and the horizontal bar of section bar is filled preferably in horizontal bar section bottom, the utility model will be shunted the bottom of horizontal bar section of bridge and the spacing distance S between the deflector end is designed to 5～10mm.
The utility model is by installing the shunting bridge additional in the charging hole of deflector, brought following benefit: the cantilever beam of (1) shunting bridge and counterdie is fitted and is compressed, aluminium alloy material stream is divided into two strands by cantilever beam, can't directly impact the cantilever beam of counterdie, the cantilever beam of counterdie is protected preferably, and the mold use life-span improves greatly; (2) cantilever beam is not easy to squeeze and collapses or squeeze partially, makes the aluminium section bar global formation more stable, and the die trial number of times reduces; (3) protection that obtains shunting bridge of the horizontal bar in the middle of aluminium section bar can not impacted by aluminium bar directly, and the wall thickness dimension of horizontal bar is more accurate.
