Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a shifting rolling device that performs required rolling by shifting rolling rolls in the axial direction in reverse rolling in which rolling materials such as shaped steel and wire rods are reciprocated on a fixed conveyance line. It is related to.

The steel from the heating furnace is inserted into the groove formed by the grooves between a pair of rolls (referred to as a caliber) between a pair of rolling rolls that have grooves of different sizes carved on the outer periphery. For example, there is a rolling method in which the pieces are passed one after another to form a predetermined cross-sectional shape.
As described in Japanese Patent No. 36142, a method has been developed in which the rolling material is simply moved back and forth on a fixed conveyance line by shifting the rolling roll in its axial direction, and does not require lateral movement.

The present invention is a shifting rolling device in which the rolling rolls are mounted on a carriage so as to move the rolling rolls in the axial direction, and the carriage is slidably disposed on the rails. It is divided at the middle part and a drainage groove is formed between them, and a cooling water outlet is provided above the drainage groove so as to face the mold groove of the rolling roll located above the drainage groove. It is characterized by this.

An embodiment of the present invention will be described below with reference to the drawings. Reference numerals 1 and 1' denote a pair of rolling rolls having a plurality of mold grooves carved on the outer periphery, and the rolling rolls 1 and 1' are formed on a carriage 2. The upper and lower stages are supported horizontally by a framework 3, and are rotated in opposite directions by a drive source (not shown). 4 indicates four wheels that support the trolley 2, and 5 indicates a cylinder that moves the trolley 2.

In this shifting rolling machine, a rail 6 on which wheels 4 roll is divided approximately at the middle in the longitudinal direction, and a drainage groove 7 is formed between the rails 6. Cooling water outlets 8 and 8' are provided above the drain groove 7 so as to face the mold groove located above the drain groove 7. 9
is an eave-like piece that prevents the scale from falling onto the rail 6;
10 indicates a cooling water pipe.

In the shifting rolling machine configured in this way, even if the rolling rolls 1 and 1' are shifted, the cooling water always flows down to the drainage groove 7 directly below the rail 6.
can be operated without getting wet, and the wheels 4 and the rails 6 can be protected from rusting. In addition, since the scale adhering to the mold grooves of the rolling rolls 1 and 1' is flushed away to the drainage ditch 7 together with the cooling water, there are beneficial effects such as minimizing the possibility of operational problems caused by scale accumulation. It is something.

Claims (1)

[Claims] 1 A pair of rolling rolls each having a plurality of pattern grooves carved on the outer periphery are supported horizontally on top and bottom on a cart, and the cart is slid on rails laid parallel to the axial direction of the rolling rolls. A shifting rolling device that can be freely arranged, the rail being divided at approximately the middle in the longitudinal direction, a drainage groove being formed therebetween, and facing oppositely to the mold groove located above the drainage groove. A shifting rolling device characterized in that a cooling water outlet is provided above the drain groove.
