Description

Cutting device and method for removing snow cutting {REMOVAL APPARATUS AND METHOD FOR BURR}

The present invention relates to an apparatus and method for removing a cutting tongue, and more particularly, to an apparatus and a method for removing the cutting tongue, which can prevent accumulation of the cutting tongue while repeating the removal operation of the cutting tongue attached to the treatment. .

In general, slabs produced continuously in an integrated steelworks are drawn along a roll of a caster, cooled to a predetermined temperature, and cut into regular lengths. The slab is cut by a torch cutting machine. At this time, due to the nature of the torch cutting machine that cuts by oxidizing and melting the slab, a burr is formed under the cut surface of the slab in the process of cutting the slab.

Failure to completely remove the cuts before transferring the slab to the subsequent process, the rolling process, can lead to delays in operation, equipment damage and product defects in the subsequent process.

Therefore, after cutting the slabs, each slab is collected for each row, and a work is performed to remove the cutting slits formed under the cut surface of the slabs. The device that does this is called the cutting-off device.

The conventional cutting-off device includes a cylindrical shear beam disposed on the lower side of the transport path of the slab and share caps mounted vertically on the outer circumferential surface. Here, the share caps are arranged in a line along the extending direction of the share beam on the outer circumferential surface of the share beam. As the slab moves along the transport path, the bottom surface contacts the share caps, and the share caps cut the cuts protruding downward from the bottom surface of the slab from the slab.

On the other hand, if the cutting tongue is attached and accumulated on the share cap, the next operation cannot be performed smoothly, which adversely affects the subsequent process and causes logistic congestion in the transfer line from the cutting of the slab to the loading.

The technology underlying the present invention is published in the following patent documents.

Along with this process, a process of discharging the cutting snow (B) is performed. That is, after processing the surface of this cast (S1) using the first cutting tip (333a), the cylinder 310 is rotated back and the second cutting tip (333b) using the surface of the next cast (S2) During processing, the first cutting tips 333a are moved to the standby position to drop and remove the residue of the cutting snow B generated during the processing of the previous cast (this cast S1). For example, while the surface treatment of the processed object is repeatedly performed at the cutting position, the ends of the removal parts 330 protruding on both sides of the outer circumferential surface of the cylinder 310 are alternately positioned in the standby position and the process of removing the cutting tongue from the removal parts is eliminated Do it together. Thus, it is possible to prevent the source of the cutting snow (B) from accumulating in the cutting snow removing device 300 while the surface treatment of the processed material is continuously performed.

10 is a longitudinal sectional view of a cutting-edge removal apparatus according to a modification of the present invention.

The apparatus for removing cutting snow according to the first modification of the present invention may further include a gas injection unit 700 in addition to the above-described configurations. The gas injection unit 700 extends into the insides of the nozzles 710 and the cylinder 310, which incline the outer circumferential surface of the cylinder 310 around the removal units 330, and the nozzles 710 An injector gas supply pipe 720 communicating with the injector gas supply pipe connected to the injector gas supply pipe 720, for example, may include an air compressor (not shown).

According to the first modified example of the present invention, while repeating the forward and reverse rotation of the cylinder 310 and alternately raising the removal units 330 to the cutting position, using the nozzle unit 710 provided on the outer circumferential surface of the cylinder 310 Injector gas, for example, air may be injected into the cutting tongue B attached to the removal unit 330 in the standby position, and the cutting tongue B may be dropped. The cutting position is a position relatively close to the lower surface of the processed object, and the standby position is a position relatively distant from the lower surface of the processed object.

11 is a longitudinal sectional view of a cutting-edge removal apparatus according to another modification of the present invention.

The cutting-edge removal apparatus according to the second modification of the present invention may further include a vibration generating unit 800 in addition to the configuration of the cutting-edge removal apparatus 300 according to an embodiment of the present invention. The vibration generating part 800 strikes the removing part 330 within the mounting holes 320 while the removing parts 330 repeat the ascending and descending, thereby generating the vibration F, thereby leaving the cutting tongue B I can do it.

The vibration generating unit 800 may include a hitting pin 381 installed on the separation plate 341 and extending in a direction intersecting the path, and a shock absorbing portion 382 formed on one side of the hitting pin 381. have. The striking pin 381 and the buffer part 382 may be connected in series. The shock absorber 382 may include an elastic body. The striking pin 381 may strike the piston 331 on which the cutting tip 333 is supported, when the cutting tip 333 approaches the outer circumferential surface of the cylinder 310, whereby the cutting tongue B Even if it is attached to the cutting team 333, it can be released by giving a shock to it.

According to the second modification of the present invention, it is possible to drop the cutting snow B attached to the removal unit 330 by hitting the removal units 330 in the standby position. Therefore, the cutting snow B which does not fall by its own weight can be smoothly removed from the outer circumferential surface of the cylinder 310.

The cutting-edge removal apparatus according to the first modified example of the present invention and the cutting-edge removal apparatus according to the second modified example may be modified in various forms by crossing or combining with each other.

The above embodiments of the present invention are for the purpose of describing the present invention and not for the limitation of the present invention. It should be noted that the configurations and methods disclosed in the above embodiments of the present invention may be modified in various forms by combining or crossing each other, and such modified examples may be viewed as the scope of the present invention. That is, the present invention will be implemented in a variety of different forms within the scope of the claims and equivalent technical spirit, and various embodiments are possible within the scope of the technical spirit of the present invention. Will be able to understand.
