Description

Inverter {Turner}

The present invention relates to an inverting device, and more particularly, to an inverting device capable of stably rotating a workpiece.

Generally, slabs produced in a continuous casting machine are cut into slabs of 40 tons or less, heated up in a reheating furnace, and then put into a hot rolling mill to produce hot rolled coils.

Cast steel produced in the continuous casting process is cut into a cast of less than 40 tons in the cutter, and is usually cooled to 100 ℃ or less while being stored in a separate yard. In order to remove defects on the surface of the cooled slab, a mechanical scarfing process is generally performed using a scarfing machine or a hand scarfing process is performed by an operator to scarf the slab using a hand torch. .

The mechanical scarfing process can scarp each edge of the cast while moving the cast using a roller table without changing the position of the cast. In comparison, the hand scarfing process is performed by the operator standing on the cast iron, so that the upper surface of the cast steel must be scarfed, and then the caster is inverted to scarf the lower surface. Therefore, in the hand scarfing process, an inverting device for inverting the object to be scarfed is required.

The reversing apparatus may be provided on one side of the conveying path of the cast steel, it may include a gripping portion is formed with a concave groove for seating the cast on the conveying path. The gripping portion is provided so as to be rotatable, and can be inverted by rotating in a state of holding the cast steel.

By the way, the recessed groove of the gripping portion has a relatively wide interval to hold the cast steel of various thickness, when rotating in the state holding the cast steel collides while flowing in the gripping portion. This is provided with a support device for supporting the slab seated on the gripping portion using a support device provided on one side of the reversing device. However, there is a problem that the support device takes a lot of time to maintain a complex structure and frequent failures.

And when the scarfing of the cast steel (S) is completed, it is possible to transfer the cast steel (S) to the place where the next process is made using the belt conveyor 400.

Referring to FIG. 2, the reversing apparatus 300 according to the embodiment of the present invention includes a pair of supports 312 and 314 spaced apart from one side of the roller table 100, and a pair of supports 312 and 314. ) May include a rotation shaft 330 rotatably connected to the rotation shaft, at least two grippers 340 connected to the rotation shaft 330, and a pressing member 350 provided at the grippers 340. At this time, one side of the support (312, 314) may be provided with a cradle 310 for installing the drive unit 210, the drive unit 210 is provided on the cradle 310, the one side of the rotary shaft 330 Can be connected.

The driving unit 210 may provide power, for example, rotational force, for rotating the rotation shaft 330. The driving unit 210 may include a motor (not shown) and a reducer (not shown).

The gripping portion 340 may be fixedly installed on the rotation shaft 330 to be rotatable with the rotation shaft 330.

The gripping portion 340 may be formed with an insertion groove 341 into which the cast (S) can be inserted at least on one side. Alternatively, as shown in FIG. 3, insertion grooves 341 may be formed on both sides of the grip part 340. The gripping portion 340 includes a lower plate 340a on which the cast steel S is seated, an upper plate 340b and a lower plate 340b provided to be spaced apart from the upper portion of the lower plate 340a. It may include a side plate (340c) for interconnecting one side of. Although the gripping portion 340 is described as including the lower plate 340a, the upper plate 340b, and the side plate 340c, each plate may be connected to each other to be integrally formed. At this time, if the lower plate 340a and the upper plate 340b has an area to be in contact with the slab S, the direction in which the slab S is inserted is called a longitudinal direction, and the direction crossing the longitudinal direction is wide. It is called a direction.

Through such a configuration, the gripping portion 340 is an insertion groove into which the slab S can be inserted through an upper surface of the lower plate 340a, a lower surface of the upper plate 340b, and one side surface of the side plate 340c. 341 may be formed. At this time, the insertion groove 341 may be formed so that the slabs of various thickness can be inserted. For example, the height of the insertion groove 341, for example, the straight line 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 slab to be processed. When the slab S is inserted into the insertion groove 341 and seated on the lower plate 340a, a space may be formed between the upper surface of the slab S and the lower surface of the upper plate 340b. When the rotating shaft 330 is rotated in this state, the slab S flows in the insertion groove 341 of the grip portion 340 and impacts the upper plate 340b or the lower plate 340a. There is a problem that the branch 340 is damaged or a defect is formed in the cast (S).

Accordingly, in the present invention, when the holding part 340 is rotated to invert the slab S, the slab S is directly placed in the holding part 340 to prevent the slab S from flowing in the insertion groove 341. The pressing member 350 which can pressurize was installed.

At least one pressing member 350 may be provided in the gripping portion 340 to press at least one of the upper and lower surfaces of the slab S. In this case, 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, and the pressing member 350 is installed on the upper plate 340b. An example will be described.

The pressing member 350 is provided inside the upper plate 340b and may include an operation rod 354 and a cylinder 352 that are movable in the vertical direction. Accordingly, the groove 342 for installing the pressing member 350 may be formed in the upper plate 340b, and the groove 342 may be formed in a shape corresponding to the cylinder 352 and the operation rod 354. .

The cylinder 352 may be installed to be embedded in the upper plate 340b. In addition, the actuation rod 354 is embedded in the upper plate 340b, that is, the recess 342, before the cast S is inserted into the insertion groove 341. Then, the cast S is inserted into the insertion groove 341. When inserted and seated on the upper portion of the lower plate 340a, the protrusion 342 may protrude from the groove 342 and may have a length enough to press the slab S.

The cylinder 352 has a space for accommodating the fluid therein, and may include a hydraulic cylinder for moving the operating rod 354 up and down according to the amount of the fluid contained in the space. The supply pipe 360a for supplying the fluid to the cylinder 352 and the 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) is connected to the cylinder 352, 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 other side of the rotating shaft 330, for example, the side connected to the driving unit 210, and installed to pass through the inside of the rotating shaft 330. have.

The actuating rod 354 can move in an up and down direction, for example, in a direction intersecting with a lower surface of the upper plate 340b, preferably in a direction perpendicular to the operation of the cylinder 352. Alternatively, the actuating rod 354 may move in a direction intersecting, preferably in a direction orthogonal to one surface, for example, the upper surface of the cast steel (S). At this time, the operation rod 354 may be formed in a cylindrical shape, or may be formed of a polyhedron such as a hexahedron.

In addition, the pressing member 350 may include a contact plate 356 to effectively press the cast (S). The contact plate 356 may be connected to the end of the actuating rod 354 in a direction intersecting the longitudinal direction of the actuating rod 354. In this case, the contact plate 356 may be integrally connected with the actuating rod 354 or may be connected to the end of the actuating rod 354 so as to be replaceable. When the slab S is pushed by the pusher 200 to be inserted into the insertion groove 341 of the grip part 340, the lower surface of the slab S comes into contact with the upper surface of the lower plate 340a. If performed repeatedly, the upper surface of the lower plate 340a may be worn. If the upper surface of the lower plate 340a is uniformly worn, there is no problem. However, since a lot of wear occurs at the end where the slab S starts to be inserted, a slope may be formed on the upper surface of the lower plate 340a. In this case, even if the slab S is pressed using the pressing member 350, a space is partially formed between the slab S and the lower plate 340a, and even though the slab S is pressed using the pressing member 350. Cast piece (S) may not be in close contact with the upper surface of the lower plate (340a). In this state, when the grip part 340 is rotated to invert the slab S, a problem may occur in which the slab S swings in the insertion groove 341 of the grip part 340. When the contact plate 356 is connected to the working rod 354 so as to be replaceable, the contact plate 356 is worn instead of the lower plate 340a, and when the contact plate 356 is worn to some extent, the new contact plate 356 is worn. By replacing the above problems can be solved.

The contact plate 356 may be formed in various sizes, and may be formed to have a size smaller than the area of the upper plate 340b so as to be embedded in the upper 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. In this case, the contact plate 356 may be formed to extend in the width direction of the upper plate 340b and may protrude to both sides of the upper plate 340b. In this case, the slab S can be gripped more stably through the contact plate 356, and is applied to the slab S by the contact plate 356 or the operating rod 354 when the slab S is inverted. Dispersion of the losing pressure can be prevented from causing a defect on the surface of the cast steel (S).

The process of rotating the cast (S) through the grip 340 by pressing the pressing member 350 on the upper surface of the cast (S) inserted into the insertion groove 341 of the grip portion 340 through such a configuration. In the cast (S) can be prevented from flowing in the insertion groove 341.

When the cast steel S is transferred to the place where the hand scarfing process is performed, the transfer of the cast steel S is stopped. Then, by using the pusher 200 provided on one side of the roller table 100 as shown in FIG. 5, one side of the cast steel S is moved to the inverting apparatus 300 provided on the other side of the roller table 100. .

Thereafter, as shown in FIG. 6, the slab S is inserted into the insertion groove 341 of the grip portion 340 and seated on the upper portion of the lower plate 340a. At this time, the holding unit 340 of the reversing apparatus 300 may maintain a horizontal state so that the cast (S) can be inserted into the insertion groove 341. In addition, the operation rod 354 constituting the pressing member 350 may maintain a state of being inserted into the upper plate 340b of the gripping portion 340, that is, of the groove 342. Here, when the pressing member is also provided in the lower plate 340a, the upper and lower portions of the slab S may be simultaneously pressed.

Pressurize). At this time, when the fluid is supplied to the cylinder 352 through the supply pipe 360a, the internal pressure of the cylinder 352 increases and the working rod 354 is pushed out, which causes the working rod 354 to the cast steel S side. Will descend.

When the rotating shaft 330 is rotated by operating the driving unit 210 in this state, the holding unit 340 connected to the rotating shaft 330 as shown in FIGS. 8 and 9 has the rotating shaft ( 330 may be rotated 180 ° to reverse the slab (S). While the cast piece S rotates while being held by the gripping portion 340, the upper surface may be in contact with the operation rod 354, and the lower surface may be in contact with the lower plate 340a. Accordingly, the state fixed in the insertion groove 341 of the gripping portion 340 may be maintained while rotating for reversal of the cast steel (S).

When the slab S is inverted, the working rod 354 is lowered as shown in FIG. 10 to seat the slab S on the upper plate 340b.

When the cast steel (S) is seated on the upper plate (340b), when the belt conveyor 400 is provided in the lower holding portion 340 is operated, the cast steel (S) is seated on the belt conveyor 400, the top for hand scarfing Is transported to position.

Then, the operator climbs on the upper part of the cast (S), when there is a part that needs to be scarfed, and using the hand torch to scarf the cast (S), and then transfer the cast (S) to the place where the subsequent process is made. On the other hand, if no scarfing is required, the cast (S) can be transferred to the place where the subsequent process is carried out.

Although the invention has been described with reference to the accompanying drawings and the preferred embodiments described above, the invention is not limited thereto, but is defined by the claims that follow.
