Description of the Related Art Extruded materials of aluminum and aluminum alloys are generally subjected to so-called press quenching in which hot-extrusion is followed by rapid cooling for the purpose of improving yield strength in the manufacturing process. Conventionally, press quenching is an air-cooling type in which a fan is blown to an extruded material that is in a high temperature state immediately after hot extrusion processing, a spray type in which a spray is blown, and a quenching tank of the extruded material provided downstream of the hot extruder It is performed by a cooling method such as a water tank type that allows water to pass through.

い。However, among the aluminum alloys used as extruded materials, JIS A2000 series and JIS A7000 series alloys have a slow extrusion rate and are sensitive to quenching. In the formula, since the cooling rate is slow, press quenching cannot be sufficiently performed,
Further, even in the water tank type, sufficient press quenching could not be performed because the extruded material was cooled down by the time it reached the quenching tank. Therefore, these JIS A2000 series and JIS A70
Regarding the extruded material of the 00 series alloy, after hot extrusion, it was reheated for solution treatment, and quenched for quenching treatment. On the other hand, it is conceivable to provide a quenching tank immediately after the die of the hot extrusion apparatus, but this is not preferable because the extrusion apparatus, in particular, the end platen needs to be largely modified.

Press hardening of the material is possible. The present invention is particularly effective when applied to JIS A2000 series and 7000 series alloys having a low extrusion speed and high sensitivity to quenching, but it is also applicable to other aluminum alloys such as JIS A6000 series. Of course it is possible.

FIG. 3 is a sectional view of an embodiment of the present invention. In FIG. 1, 1 is a container, 2 is a ram, 3 is a billet, 4 is a die ring, 5 is a die, 6 is a backer, 7 is a bolster, 8 is an end platen, 9 is a canister, and 15 is an extruded material. An injection nozzle 10 that injects cooling water 13 is provided on the side of the canister 9 near the die 5, and an injection nozzle 1 is provided at both ends of the canister 9.
Cooling water 13 injected from 0 and filling the canister 9
There are lids 11 and 12 for accumulating in the canister 9. The extruded material 15 extruded from the die 5 passes through the opening of the lid 11 of the canister, enters the canister 9, and is rapidly cooled by the cooling water jetted from the jet nozzle 10 and the cooling water 13 filled in the canister 9. It The cooling water 13 in the canister 9 flows in the extrusion direction (the direction of the arrow in the drawing) along with the movement of the extruded material 15 and the water flow caused by the injection of the cooling water from the injection nozzle 10, and the drain port 14 provided on the downstream side of the canister 9 Drained from. Therefore, the cooling water 13 in the canister 9 is always kept at a low temperature. Also,
Since the lid 11 is provided on the die 5 side of the canister 9 even if the cooling water 13 flows backward (in the direction opposite to the arrow in the figure),
There is no risk of the hot die 5 being rapidly cooled by the backflowing cooling water and being destroyed. Note that the cooling water 13 may be stored in the canister 9 by a so-called air curtain, which blows air strongly instead of the lids 11 and 12.

Therefore, it is possible to reduce the labor, time, and energy required to reheat and quench the hot extruded material that has once been cooled, and to reduce the cost. Further, since the present invention is a modification of the canister of the conventional extruder, it is not necessary to modify the conventional extruder to a great extent, and it is economical and has significant industrial effects.
