Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a slab processing device attached to a cutting torch that continuously cuts slabs in-line.

Conventionally, the rollers installed on the rear surface of the cutting torch are either a darting roller a (Fig. 1) that lowers the rollers one after another in order to prevent molten slag from adhering to the roller when the cutting torch 1 approaches; Travel roller b moving parallel to 1
(Figure 2) was common.

However, the shortest length of slab that can be transferred using these conventional methods is limited to about 2 m, but with the latest equipment, the crop at the tip and rear end of the slab, and the cut off part at the joint between successive castings, can be reduced to 1 m or less. Because I do,
In conventional methods, this crop could not be processed in-line, but instead was taken out of the machine uncut and cut off-line.

As a result, additional work is required to cut the slabs and crops, and this has to be done manually, which has the disadvantage of increasing operating costs. In addition, in the case of a travel roller, if the burr attached to the cut end surface of the slab becomes large, it becomes difficult to return to the original position.

The present invention was proposed in order to solve the above-mentioned conventional drawbacks, and it is a slab processing device that can carry out crops of about 1 m or joints of continuous castings even if they are separated from slabs of a specified length. It is attached to a torch-type cutting machine that cuts continuous slabs in-line with the purpose of obtaining In a slab processing apparatus having a movable table, the movable table has a travel mechanism that reciprocates on a guide rail extending in the same direction as the slab movement direction between the front table of the cutting machine and the rear table of the cutting machine. a table, an elevating table that is moved up and down by an elevating cylinder installed on the travel table and has a roller on which the slab is placed; a drive device that rotationally drives the roller; A pusher is provided on one side of the rear table to push out short crops that have been moved onto the rear table in a direction perpendicular to the moving direction of the slab; Furthermore, on the other side of the rear table, there is a skid table on which the crop pushed out by the pusher can be placed and slid. If you do,
By using a moving table installed at the rear of the cutting machine, and by making the table itself and rollers self-propelled, it is possible to transfer slabs or short crops onto the conveyance table, and the crops can be transferred immediately to the cross conveyor. It is an object of the present invention to provide a slab processing device which is characterized by having a mechanism that allows the slab to be carried out from the table to the outside of the production line by using the above-mentioned tools, etc., and which is characterized by saving labor.

Embodiments of the present invention will be described below with reference to the drawings. FIGS. 3 and 4 show embodiments of the present invention, and in the case of the drawings, the drawings show the steps immediately before cutting for conveying a slab of a predetermined length during casting. It shows the condition. In the figure, 1 is a cutting torch, 2 is a guide rail on which the torch 1 moves, 3 is a slab, 4 is a cutting machine front table, and 5
1 is a lifting table, 6 is a lifting cylinder, 7 is a travel table, 8 is a guide rail for the travel table, 9 is a drive wheel, 10 is a clamp, 11 is a rear table of the cutting machine, 12 is a cutting command transmitter, 1
3 is a travel table drive device, 14 is a pusher, 15 is a skid table, and 16 is a roller drive device.

Now, in order to cut the slab being cast by the cutting torch 1, the front table 4 and the rear table 11 of the cutting machine are used.
A travel table 7 that moves in sync with the slab is provided between them, and can be moved back and forth via a drive device 13 and drive wheels 9. Further, the elevating table 5 is installed on a travel table, and is moved up and down by an elevating cylinder 6.

The rollers of the lifting table are provided with a drive device 16 so that the slab can be transported. Further, on the entry side of the rear table, a pusher 14 and a skid table 15 are provided for removing short crops of about 1 m from the line.

Next, the operation will be described. When the tip of the slab 3 reaches the cutting command transmitter 12 from the state shown in FIGS. 3 and 4, the torch 1 starts cutting while moving in synchronization with the slab 3. Travel table 7 has clamp 10
It moves in synchronization with the slab. When cutting is completed, the travel table 7 carries the slab with the slab placed thereon to the rear table by the drive device 13, and drives the rollers to carry out the slab.

When the slab is carried out, the transfer table 7 reverses the driving device 13 and returns to its original position. At this time, the lifting table 5 lowers the lifting cylinder 6 to provide a gap between the lifting cylinder 6 and the slab, so that even if there is a burr such as cutting slag on the cut surface of the slab, there is no problem with the return.

Next, when processing a short crop, use the fifth
When a cutting command is issued from the state shown in the figure, the lifting table 5 rises, and the clamp 10 causes the slab and the lifting table to move in synchrony, and at the same time, the driving device 1
3 is also driven, and a tensile force is applied to the extent that no slipping occurs between the slab and the clamp 10. When the crop is cut off, the crop is placed on this table and transferred, and when the stroke end is reached (Fig. 6), the roller table is driven, the crop is transferred to the rear table of the cutting machine, and the pusher 14 moves the crop to the side of the line. Transfer to skid table 15.

Since the present invention is configured as described above in detail, it is possible to separate short crops of about 1 m or joints between successive castings from the slab, and transport and store the slabs, crops, etc. separately. In addition, after cutting off a short crop, it is equipped with a drive device that moves the transfer cart back and forth and a drive device that drives the rollers when transporting the crop to the rear table and sending the crop further from the stroke end. , cutting, and transport operations can be carried out smoothly. Because the transfer trolley is equipped with a lifting table,
When a slab or crop is returned to its original position after being sent out, interference can be prevented even if there are burrs on the cut end surface.
