BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reversing device, and more particularly, to a reversing device capable of stably rotating and reversing a processed object.

Generally, a slab produced in a continuous casting machine is cut into a cast steel having a weight of 40 tons or less, heated in a reheating furnace, and then introduced into a hot rolling mill to produce a hot-rolled coil.

The slabs produced in the continuous casting process are cut into slabs of 40 tons or less from the slabs, and then cooled to a temperature of 100 ° C. or less while being stored in a separate yard. In order to remove defects generated on the surface of the cooled cast steel, a mechanical scarfing process is usually carried out using a scarfing machine or a handscalling process is performed in which an operator scorps the cast using a hand torch .

The mechanical scarping process can scour each corner of the casting while moving the cast using a roller table without changing the position of the casting. On the other hand, the handscaping process is carried out by the worker on the casting, so the upper surface of the casting must be scoured and the casting must be reversed to scour the lower surface. Therefore, in the hand scarping process, a reversing device for inverting the scraps to be scarf is required.

The reversing device may include a grip portion provided at one side of the feeding path of the cast steel and formed with a concave groove for seating the cast on the conveying path. The gripping portion is provided so as to be rotatable, and the casting can be reversed by rotating the casting while grasping the casting.

However, the recessed groove of the gripping portion has a relatively wide gap so as to grasp the casting pieces of various thicknesses, and when the casting piece is rotated while holding it, the casting piece is collided while flowing in the gripping portion. And a supporting device for supporting the casting seated on the gripping part by using a supporting device provided on one side of the reversing device. However, the supporting device has a problem in that it takes a long time to maintain and repair due to complicated structure and frequent failures.

The grip portion 340 may be fixed to the rotary shaft 330 so as to be rotatable together with the rotary shaft 330.

The grip portion 340 may be formed with an insertion groove 341 into which at least one side S can be inserted. Alternatively, insertion grooves 341 may be formed on both sides of the grip portion 340 as shown in FIG. The grip portion 340 includes a lower plate 340a on which the slab S is placed and an upper plate 340b spaced from the upper portion of the lower plate 340a and a lower plate 340b on one side of the lower plate 340a, And a side plate 340c that interconnects one side of the side plate 340c. Here, although the grip portion 340 is described as including the lower plate 340a, the upper plate 340b, and the side plate 340c, the respective plates may be connected to each other to be integrally formed. At this time, if the lower plate 340a and the upper plate 340b have an area so as to be in contact with the slab S, the direction in which the slab S is inserted is referred to as a longitudinal direction and the direction crossing the longitudinal direction is defined as a width Direction.

Through the above-described structure, the grip portion 340 can be inserted into the insertion groove 341 through which the slab S can be inserted through the upper surface of the lower plate 340a, the lower surface of the upper plate 340b, (341) can be formed. At this time, the insertion groove 341 can be formed in a margin so that the main thread of various thickness can be inserted. For example, the straight distance from the upper surface of the lower plate 340a to the lower surface of the upper plate 340b may be greater than the thickness of the thickest cast billet. A space may be formed between the upper surface of the cast steel S and the lower surface of the upper plate 340b when the cast steel S is inserted into the insertion groove 341 and seated on the lower plate 340a. When the rotary shaft 330 is rotated in this state, the cast steel S undergoes an impact on the upper plate 340b and the lower plate 340a while flowing in the insertion groove 341 of the grip portion 340, There is a problem that the support portion 340 is damaged or a defect is formed in the cast steel S.

Therefore, in order to prevent the slab S from flowing in the insertion groove 341 when the slab S is reversed by rotating the gripper 340, the slab S is directly inserted into the gripper 340 A pressing member 350 is provided.

At least one pressing member 350 may be provided in the grip portion 340 to press at least one of the upper surface and the lower surface of the slab S. [ At this time, the pressing member 350 may be provided on at least one of the lower plate 340a and the upper plate 340b of the grip portion 340. Here, the pressing member 350 is installed on the upper plate 340b Will be described.

The pressing member 350 may be provided inside the top plate 340b and may include an actuating rod 354 and a cylinder 352 movable in the up and down direction. The upper plate 340b may be provided with a groove 342 for mounting the pressing member 350 and the groove 342 may be formed in a shape corresponding to the cylinder 352 and the actuating rod 354 .

The cylinder 352 may be installed to be embedded in the upper plate 340b. The work rod 354 is embedded in the upper plate 340b or the groove 342 before the cast S is inserted into the insertion groove 341 and the cast S is inserted into the insertion groove 341 And may be formed so as to protrude from the groove 342 and press the slab S when the slab 350 is inserted into the upper portion of the lower plate 340a.

The cylinder 352 may include a hydraulic cylinder in which a space capable of accommodating a fluid is formed and capable of moving the operation rod 354 in the vertical direction according to the amount of the fluid accommodated in the space. A supply pipe 360a for supplying the fluid to the cylinder 352 and a discharge pipe 360b for discharging the fluid in the cylinder 352 may be provided. One side of the supply pipe 360a and the discharge pipe 360b may be connected to the cylinder 352 and the other side may be connected to a reservoir (not shown) for storing the fluid. The supply pipe 360a and the discharge pipe 360b may be inserted into the inside of the rotating shaft 330 through the opposite side of the other side of the rotating shaft 330 connected to the driving unit 210, have.

The operation rod 354 can move in the up-and-down direction, for example, in a direction intersecting with the lower surface of the upper plate 340b, preferably orthogonal, by the operation of the cylinder 352. [ Alternatively, the operating rod 354 may move in one direction, for example, in a direction intersecting with the upper surface, preferably orthogonal, of the slip S. At this time, the operation rod 354 may be formed into a cylindrical shape or a polyhedron such as a hexahedron.

In addition, the pressing member 350 may include a contact plate 356 to effectively pressurize the cast S. The contact plate 356 may be connected to the end of the actuating rod 354 in a direction crossing the longitudinal direction of the actuating rod 354. At this time, the contact plate 356 may be integrally connected with the operation rod 354 or may be interchangeably connected to the end of the operation rod 354. When the cast steel S is pushed into the pusher 200 and inserted into the insertion groove 341 of the grip portion 340, the lower surface of the cast steel S is brought into contact with the upper surface of the lower plate 340a, Repeatedly, the upper surface of the lower plate 340a may be worn. There is no problem if the upper surface of the lower plate 340a is uniformly worn, but a slope can be formed on the upper surface of the lower plate 340a because a large amount of wear occurs at the end where the cast S starts to be inserted. In this case, even when the cast steel S is pressed by using the pressing member 350, a space is partially formed between the cast steel S and the lower plate 340a, and even if the cast steel S is pressed using the pressing member 350 The cast steel S may not be in close contact with the upper surface of the lower plate 340a. In this state, when the gripper 340 is rotated to invert the strip S, there may arise a problem that the strip S is swung in the insertion groove 341 of the gripper 340. When the contact plate 356 is replaceably connected to the operating rod 354, the contact plate 356 is worn instead of the lower plate 340a, and when the contact plate 356 is worn to some extent, It is possible to solve the above-mentioned problems.

The contact plate 356 may be formed in various sizes and may have a size smaller than the area of the top plate 340b so as to be embedded in the top plate 340b.

Alternatively, as shown in Fig. 4, the contact plate 356 may be formed to have the same size as the area of the upper plate 340b.

In addition, the contact plate 356 may be formed larger than the area of the upper plate 340b, as shown in Fig. At this time, the contact plate 356 may be formed to extend in the width direction of the upper plate 340b and protrude to both sides of the upper plate 340b. In this case, it is possible to grasp the slab S more stably through the contact plate 356 and to apply the slab S to the slab S by the contact plate 356 or the operating rod 354 when reversing the slab S It is possible to suppress the generation of defects on the surface of the cast slab S by dispersing the low pressure.

With this configuration, the upper surface of the cast steel S inserted into the insertion groove 341 of the grip portion 340 is pressed by the pressing member 350 to rotate the cast steel S through the grip portion 340 It is possible to prevent the cast steel S from flowing in the insertion groove 341. [
