Description

Description: FIELD OF THE INVENTION The present invention relates to a method of reducing the width of a running horizontal opposed type press used for reducing the width of a slab upstream of a rolling line or downstream of a continuous casting line, and The present invention relates to a horizontal facing press between runs.

[Prior Art] Conventionally, an apparatus for forming a slab is disclosed in Japanese Patent Application Laid-Open No. 62-6864.
No. 6, JP-A-62-192222, there is a device disclosed in JP-A-62-68646.If the device disclosed in JP-A-62-68646 is described, the rotational movement of the crankshaft is slid via a connecting rod. And the slide is reciprocated in the width direction of the steel slab (slab), so that the mold is brought into contact with the end face in the width direction of the slab so that the slab is reduced in width. By reciprocating the traveling guide block in the slab longitudinal direction by, the mold is reciprocated also in the slab longitudinal direction, and while the slab is moved in the slab longitudinal direction by the feeding device, width reduction molding is performed over the entire slab length. I want to.

In addition, if the apparatus disclosed in Japanese Patent Application Laid-Open No. 62-192222 is described, the apparatus is mainly intended to maintain the balance between the load points of the right and left dies during width reduction, and to reduce the hydraulic pressure reduction cylinder. By moving the piston rod forward, the mold is brought into contact with the slab width direction end face via the mold support to reduce the width of the slab, and the width reduced slab is positioned at both width end positions on the exit side of the press housing. Based on the camber amount detected by each camber detector and calculated by the camber calculator based on the detected value, the mold moving calculator calculates the optimum position of the mold, the fluid pressure cylinder operates, and the mold is moved. The slab is moved forward or backward in the direction of travel.

[Problems to be Solved by the Invention] However, among the above-mentioned devices, in the device disclosed in Japanese Patent Application Laid-Open No. 62-68646, a slab feeding device and a feeding device for moving a mold forward or backward in the slab advancing direction are used. No specific means for synchronizing with the cylinder is disclosed.

Further, in the apparatus disclosed in Japanese Patent Application Laid-Open No. 62-192222, a mechanism for moving the load point of the mold may be used as a mechanism for synchronizing the moving speed of the slab and the mold. However, there is a problem that the control device becomes too complicated.

Furthermore, even if the movement speed of the mold in the slab traveling direction and the movement speed of the slab are synchronized using a mechanical interlocking device such as a crankshaft, a connecting rod, etc., the device is still too mechanically complex, There are problems that the maintenance and inspection of the device become difficult and that it is impossible to follow high-speed operation.

The present invention solves the above-mentioned problems, and makes the moving speed of a mold in the direction of a slab conveying line coincide with the moving speed of a slab moving on the slab conveying line, and facilitates maintenance and inspection of the apparatus. It is intended to be.

[Means for Solving the Problems] In order to achieve the above-mentioned object, in the method for reducing the width of the running horizontal opposed type press according to the present invention, when reducing the width of the slab sent from the slab transport line, gold is reduced. When the mold is reduced in width across the slab, the slide equipped with the mold is sent to the downstream side of the slab transport line by moving the slab, and if the mold is separated from the slab width reduction molding surface, The slide on which the mold is mounted is moved to a predetermined position on the upstream side of the slab transfer line by the home position return device. In performing the width reduction method, the slide on which the mold is mounted is moved to the slab. In addition to providing a reciprocating movement so as to sandwich the transfer line, a fixed position return device capable of moving the slide in parallel with the slab transfer line is provided, and a slab is connected to the slab transfer line via the slab. It is preferable to use a device having a configuration provided with a slab transfer device that translates the slide in parallel.

To describe the apparatus more specifically, a slide mounted with a mold and disposed so as to sandwich the slab transfer line,
A shaft box provided on the side of the slide opposite to the slab transfer line so as to be movable in the slab width direction, a crankshaft supported on the shaft box, and a connecting rod for connecting an eccentric part of the crankshaft to the slide. A fixed position return cylinder connected to the slide and extending in the slab transfer direction;
A slab transfer device provided on the slab transfer line.

The direction of the axis of the crankshaft may be either horizontal or vertical.

[Operation] In the width reduction method of the running horizontal opposed type press as described above, when the width of the slab sent from the slab conveyance line is reduced, when the mold is reduced in width across the slab, The mold is sent to the downstream side of the slab conveyance line by the slab, and when the mold is separated from the width reduction molding surface of the slab, the mold is moved to a predetermined position on the upstream side of the slab conveyance line by the home position return device. Therefore, the moving speed of the mold in the direction of the slab conveyance line when the mold lowers the width of the slab is equal to the moving speed of the slab on the slab conveyance line.

Further, in the run-to-run horizontal opposing press of the present invention, the crankshaft is rotated to reciprocate the slide in the slab width direction to reduce the width of the slab, and the mold is used to perform the width reduction of the slab width direction end face. Release the constraint of the slide in the slab conveyance line direction by the home position return cylinder, and when the mold separates from the slab width reduction molding surface, move the slide to a predetermined position on the upstream side of the slab conveyance line by the home position return cylinder. return.

Therefore, the moving speed of the mold in the direction of the slab conveyance line when the mold reduces the width of the slab and the moving speed of the slab moving on the slab conveyance line by the slab conveyance device match.

Claims (5)

(57) [Claims] When a slab sent from a slab transfer line is reduced in width by a slab, the slide on which the dies are mounted is transferred by moving the slab. When the mold is separated from the slab width reduction molding surface, the slide on which the mold is mounted is moved to a predetermined position on the upstream side of the slab conveyance line by a home position return device. Width reduction method of horizontal facing type press during running. 2. A slab transfer line, wherein a slide on which a mold is mounted is provided so as to be able to reciprocate so as to sandwich the slab transfer line, and a fixed position return device which can move the slide in parallel with the slab transfer line. A slab transfer device that translates the slide in parallel through the slab. 3. A slide mounted with a mold and disposed so as to sandwich the slab transfer line, a shaft box provided on the side of the slide opposite to the slab transfer line so as to be movable in the slab width direction, and a shaft. A crankshaft supported by a box, a connecting rod connecting the eccentric part of the crankshaft and the slide, a fixed position return cylinder connected to the slide and extending in the slab transfer direction, and a slab provided on the slab transfer line A run-to-run horizontal facing press characterized by comprising a transfer device. 4. The press according to claim 3, wherein the crankshaft is supported horizontally. 5. An apparatus according to claim 3, wherein said crankshaft is supported vertically.
