[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a high-pressure press and a method for using the same.

[0002]

2. Description of the Related Art FIG. 5 shows an example of a rolling mill used for hot rolling.
Work rolls 2a and 2b, which are vertically opposed to each other across a transport line S through which
Copy roll 3 abutting on a and 2b from the side opposite to the transport line
a, 3b.

In the above-mentioned rolling mill, the work roll 2a above the transfer line S is rotated counterclockwise and the work roll 2b below the transfer line S is rotated clockwise, so that the two work rolls 2a and 2b are rotated. By moving the molding material 1 from the upstream side of the conveying line A to the downstream side of the conveying line B by pressing the upper retaining roll 3a downward while biting the molding material 1 in between, 1 is pressed down in the thickness direction, but unless the biting angle θ of the work rolls 2a and 2b with the material 1 is set to be less than about 17 degrees, the upper and lower surfaces of the material 1 and both work rolls are formed. 2a, 2
b, slip occurs between the outer peripheral surface of the work rolls 2a,
2b cannot bite the material 1 to be molded.

That is, the diameter D of the work rolls 2a and 2b is 1
If it is 200 mm, the work rolls 2a, 2
b, the amount of reduction ΔT in one reduction molding is about 50 mm, and the thickness T0 is 2
The thickness T1 of the 50 mm material to be molded 1 after rolling down with a rolling mill is about 200 mm.

[0005] Therefore, conventionally, reverse rolling is performed by sequentially reducing the thickness of the material 1 while reciprocating the material 1 with respect to a rolling mill. After the thickness of the material 1 becomes approximately 90 mm, the reverse rolling is performed. The molding material 1 is sent to a finishing mill.

As shown in FIG. 6, a mold 4a, 4a,
4b are vertically opposed to each other with the transport line S interposed therebetween, and the two dies 4a and 4b are brought close to and separated from each other in a direction orthogonal to the molding material 1 by reciprocating means such as an eccentric shaft and a rod or a hydraulic cylinder. It is also conceivable that the material to be molded 1 having a plate thickness T0 of 250 mm is pressed down so that the plate thickness T2 becomes about 90 mm.

[0007] The dies 4a and 4b are connected to the upstream A of the transfer line.
Transfer line S gradually from the side to the transfer line downstream B side
Forming surfaces 5a, 5b close to
5b, and has flat molding surfaces 6a and 6b facing the transport line S in parallel.
The width of 6a, 6b is set according to the plate width of the material 1 to be molded.

[0008]

However, when the material to be molded 1 is reverse-rolled by a rolling mill as shown in FIG. 5, since the material to be molded 1 is long, the material is upstream of the conveying line S of the rolling mill. It is necessary to provide a material drawing-out place corresponding to the length of the molding material 1 on each of the A side and the downstream B side, and the equipment becomes large.

Also, the molds 4a and 4b shown in FIG.
In the case where the molding material 1 is pressed down in the thickness direction, when viewed from the side of the transport line S, compared to the position of the lower surface of the molding material 1 immediately before being pressed down by the dies 4a and 4b. Molded material 1 sent from molds 4a and 4b after thickness reduction
The position of the lower surface of is increased by half the amount of reduction.

As a result, the tip of the molding material 1 tends to hang downward, and a table roller for supporting the molding material 1 installed on the downstream side B of the conveying line of the dies 4a and 4b. (Not shown), there is a concern that the leading end of the molding material 1 may get caught and damage both the table roller and the molding material 1.

Since the elevating table roller is set so that the molding material after being reduced in the thickness direction is substantially horizontal, it is possible to prevent the molding material after the compression molding from being caught on the downstream table roller, and to reduce the molding material. It can be reliably transported to the downstream side.

(7) In any of the methods of using the high-pressure press device according to any one of claims 7 to 9 of the present invention, the height position of the lifting / lowering table roller is determined by changing the height of the upstream table roller and the downstream table roller. Since the molding materials are set at the same height position, the molding material that is not reduced by the mold can be reliably transported to the downstream side.
