BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facility for manufacturing various types of steel such as H-section steel and T-section steel obtained by welding a flange material and a web material.

[0002]

2. Description of the Related Art Conventionally, as this type of equipment, there is a type in which a steel mold which has been passed through a processing machine from one direction is inverted by a reversing device and then passed through the processing machine from the other direction. The processing machine includes a temporary assembly machine for welding and a straightening machine for removing distortion after welding. As the reversing device, for example, a hanging reversing device or an arm reversing device is provided.

[0003] Here, the suspension type reversing device inverts the shape steel by suspending the shape steel on a conveyor forming a conveying path from the processing machine via a suspending wire and adjusting the feed amount of the suspending wire. And then returned to the conveyor. The arm-type reversing device reverses the shape steel by rotating a V-shaped arm reciprocally over the shape steel on the conveyor over 90 degrees.

[0004]

However, according to the above-mentioned conventional double reversing device, in the case of the H-section steel, the top and bottom of the pair of flange plates are simply changed. Is reversed, the free edge of the web plate faces downward, and this free edge and one side edge of the flange plate are received by the conveyor. It cannot be read through.

Further, when the processing machine is a temporary assembling machine for welding, another flange plate is positioned below the free edge of the web plate and is passed through the temporary assembling machine. Since one side edge of the flange plate is received by the conveyor, another flange plate cannot be inserted below the free edge of the web plate.

The object of the present invention is to provide a mold steel manufacturing facility capable of automatically and easily and reliably reversing the mold steel, carrying the reversed mold steel into the processing machine inlet, and inserting another flange plate. In the point of providing.

[0007]

In order to achieve the above-mentioned object, the reversing device in the mold steel manufacturing equipment of the present invention is designed to support the mold steel.

When a freely elevating body lifting with respect to the main body consists of a rotatable clamping device around the mounted and longitudinal axis to the lift, these clamping devices
Is configured so that the steel web material on the conveyor can be clamped .

[0008]

According to the structure of the present invention, the shaped steel which is moved in the length direction is subjected to various treatments such as clamping pressure correction for the flange material and welding connection between the flange material and the web material in the processing machine. Then, the processed mold steel passes through the processing machine and is supported and guided by the conveyor . At this time, in the reversing device, the movable holding device is at the position most apart from the stationary holding device (retracted position), and In the stationary holding device, the clamp device, which is integrated with the lifting body in the raised position, performs the clamp opening movement. Further, in the movable holding device, the clamp device, which is integrated with the elevating body in the lowered position, performs the clamp opening movement. Therefore, the shaped steel that has passed through the processor is
It can be passed under the clamp device in the stationary holding device while being guided by a conveyor to approach the clamp device of the movable holding device.

When the shape steel is fed from the processor side, first, the movable holding device is moved closer to the stationary holding device, and the front end of the web material is positioned on the clamping device.
The front end of the web material can be clamped by the clamp device. Then, by moving the movable holding device away from the stationary holding device, the sandwiched mold steel can be pulled out and moved, and the rear end of the mold steel can pass below the clamp device of the stationary holding device.

Then, the elevating body of the stationary holding device is lowered to make the clamp device face the rear end of the mold steel, and then the movable holding device is moved closer to the stationary holding device to push in the clamped mold steel. The rear end of the web material can be clamped by clamping the rear end of the web material on the clamp device.

In this way, after both ends of the web material are clamped by the clamp devices, both elevating bodies are synchronously lifted to lift the die steel from the conveyor ,
By rotating both clamp devices around the longitudinal axis,
The shape steel can be inverted around the front-back axis. After performing the desired inversion, both lifting body is lowered to the synchronous shape conveyor type steel
By returning to the upper position, the clamp for the rear end of the web material by the clamp device of the stationary holding device can be opened.

Next, the movable holding device is moved away from the stationary holding device to pull out and move the sandwiched mold steel, and then the elevating body of the stationary holding device is lifted to move the clamp device to the rear end of the mold steel. May be located above. In this state, by moving the movable holding device toward the stationary holding device, the rear end of the mold steel can be pushed into the processing machine,
Then, by opening the clamp for the front end of the web material by the clamp device of the movable holding device, the shaped steel can be passed through the processing machine in the opposite manner to the above, and various processing such as pinching correction and welding connection can be performed in the same manner. You can do it.
