Description

[Detailed description of the invention] This invention involves reheating a rolled steel or metal material that has been processed into a semi-finished product in a heating furnace, and then rolling the heated rolled material into a steel bar or wire rod. This relates to a guiding device for rolling material that guides it to a predetermined rolling line before flowing to the rolls, and relates to an extraction device that has the function of guiding the rolled material that is continuously sent in a line to each caliber of the rolling rolls. It is.

In conventional guiding devices, after the heated rolled material is generally clamped with a cylindrical roller, the main body frame supporting the clamp roller is twisted by a cylinder mechanism to 30° to 45°, and then the clamp roller is rotated. It is rotated by a hydraulic motor and guided to each caliber of the rolling roll.

The conventional device mentioned above has a complicated mechanism and suffers from pin wear and
There are many oil leaks related to malfunctioning cylinders, and the forced twisting mechanism is having a negative impact on various parts.

Another method is a device in which a heated rolled material is clamped and twisted using fixed and moving Soroban rollers. In this method, stationary Soroban round rollers are placed at the left and right bottom of the rolling line, and one moving Soroban round roller is installed above the rolling line, and a clamping mechanism using a cylinder clamps and twists the rolling line.

However, since the above-mentioned Soroban ball-shaped roller for upper movement is cantilevered and moves horizontally to clamp on a single shaft, the roller may play so much that complete clamping may not be possible. In addition, this device only performs clamp twisting, and it is impossible to guide conveyance to each caliber of the rolling roll, so another conveyance device must be installed, and there are problems with the installation area of the device and the synchronization of twisting and guided conveyance. There are many problems during rolling.

The present invention was made in order to solve the problems in the above-mentioned conventional example. A lateral movable main body base 1 and a traversing device 2; a fan-shaped cylindrical operating roller 5 having a slip prevention flange that clamps the rolled material 9 and rotates on the upper part of the main body base;
6 is a rolling material guiding device constructed by installing cylinders 7 and 8 on both sides of the rolling line d, and installing a hydraulic motor for driving rollers at the bottom thereof.

Hereinafter, a detailed description will be given based on the embodiment apparatus shown in FIGS. 1 to 3.

The rolled material 9 is sent out from the heating furnace 4 to a guide device 10 by a device that sequentially extrudes it. After the rolled material 9 has passed 2 to 3 meters above the guide device 10, the clamp cylinders 7 and 8 are placed on both sides of the rolling line d, and the clamp cylinders 7 and 8 are placed on both sides of the rolling line d.
While shifting in the direction, the rolled material 9 is clamped and twisted by fan-shaped cylindrical working rollers 5, 6 having anti-slip flanges, and at the same time, the fan-shaped cylindrical working rollers 5, 6 are rotated by a hydraulic motor drive. , to each caliber of the rolling roll 3.

The torsion of the fan cylindrical movable rollers 5 and 6 due to the clamp will be explained in detail with reference to FIG.
The fan cylindrical working roller 5 has a large fan shape at the top, and the fan cylindrical working roller 6 has a fan shape with a large bottom and a flange for preventing slippage.

Only the fan cylindrical operating rollers 5 and 6 are used to roll the rolled material 9.
When moving in the clamping directions a and b, the rolled material 9 is contacted and clamped at two diagonal corners of the rolled material 9, and at the same time the rolled material 9 is twisted in the c direction.

At the same time as the twisting is completed, the fan cylindrical operating roller 5,
6 is rotated by a hydraulic motor for driving the roller and guided to each caliber of the rolling roll 3. The fan angle α of the fan cylindrical operating rollers 5 and 6 is preferably 45° to 60°, and the angle is such that both rollers can be twisted at the same time as they come into contact with the rolled material.

Since the present invention has the above-mentioned structure and operation, it not only solves all the problems of the conventional equipment mentioned above, but also brings great industrial benefits such as shortening the rolling time schedule, preventing the occurrence of defects in rolled materials, and improving the yield. It is an effective and practical device.
