Description

Cutting steel sheet tilting device {APPARATUS FOR TILTING CUTTING STRIP}

The present invention is a cutting operation to cut the defective part of the steel sheet before the welding joint of the preceding and subsequent strips to perform the continuous annealing operation of the cold rolled steel sheet, the cut steel sheet is left between the top coat and the bottom knife of the cutter and the other steel sheet TILTING APPARATUS is a cutting steel sheet for preventing the cutting failure of the.

In general, in the production of cold rolled steel sheet, in order to perform continuous work, for example, continuous annealing of the steel sheet, the end portion (END) of the preceding steel sheet and the tip portion (TOP) of the trailing steel sheet are joined by welding. Before joining work, the defective part of steel plate should be cut off first.

In FIG. 1A, a cutting operation of such a steel sheet is illustrated. When the steel sheet 100 is positioned between the upper and lower roads 110 and 120 having the knife 112 and 122 mounted to one side of the lower and upper portions, respectively, During the lowering operation of the top coat 110, the steel plate 100 is cut as the knife 112, 122 of the top, bottom 110, 120.

However, as shown in FIG. 1B, during the cutting operation of the steel sheet 100, the cut steel sheet, that is, the strap portion 100 ′ frequently remains on the knife 122 portion of the undercoat 120. In particular, the strap of the cut steel sheet 100 'is not rectangular but irregular polygons, that is, one side is short side and the other side is long side polygonal shape remaining on the lower knife 122.

As a result, as shown in FIG. 2A, the residual cut steel sheet 100 ′ is formed by cutting the cut steel sheet 100 ′ remaining on the lower knife 122 as described above during the next cutting operation of the other steel sheet 100 ″. While cutting at the same time, the cutting operation of the other steel plate 100 ″ causes a cutting failure that is not made completely.

On the other hand, the tilting operation of the conventional cut steel sheet (TILTING) in order to avoid the poor cutting for scrap, such as the residual cut steel sheet 100 ', as shown in Figure 2b, the knife 122 of the lower road 120 After installing a plurality of tilting plate 140 to be driven as the rotating shaft 130 to be transversed to the lower road 120 in the portion 126, the adjustment bolt 124 is installed to adjust the gap, as a sensor (not shown) When the cutting steel plate 100 'remaining on the lower knife 122 is sensed, when the rotating shaft 130 is driven, the remaining cutting steel plate 100' is pushed outward as the tilting plate 140 which rotates integrally. will be.

However, in the conventional steel plate tilting operation as described above, as shown in FIGS. 2B and 2C, when the remaining steel sheet 100 ′ remains on the lower knife 122, the entire portion thereof is always tilted. When the tilting plate 140 is rotated frequently, the residual cutting steel plate 100 'is pushed into the inside of the cutter rather than the front side of the cutter. It happens.

Therefore, the cutting steel sheet 100 'which is pushed back to the cutting machine side causes a malfunction of the cutting machine itself, resulting in work delay of the continuous line of the cold rolled steel sheet, and there are various problems such as lowering the productivity due to the delay of manufacturing the cold rolled steel sheet.

The present invention has been made in order to improve the various problems as described above, the object of the present invention is to simplify the strap of the cutting steel sheet remaining on the lower part of the cutter portion of the cutting machine of the preceding and the following steel plate for welding work of cold rolled steel sheet By removing the outer side of the cutting machine, it is possible to prevent the failure of cutting the steel sheet by the steel sheet to improve the production productivity of the cold rolled steel sheet, while providing a cutting strip tilting device that is easy to manufacture and install the device as a simple structure using magnetic. It's there.

The fixing means 50 for fixing the steel sheet scrap S 'and the tilting means 70 for tilting the steel sheet scrap S' fixed between the fixing means 50 are largely divided. Looking in detail as follows.

As shown in FIGS. 3 and 4, the shaft 40 is formed as a straight rod, integrally penetrates the lower road 30 in the longitudinal direction thereof, and passes through the lower road seating portion 30a. It is inserted in 30b.

Next, the fixing means 50 is shown in FIGS. 3 to 5, and the fixing means 50 is inserted into the seating portion 30a so as to be rotatable to the shaft 40, so that the remaining steel scrap S Fix the ').

That is, the fixing means 50 is formed of a two-stage electromagnet block having an opening 52 in which the shaft 40 is inserted and supported in front and connected to each other to fix the shaft 50 and the bolt 54. The first lifting cylinder 56 vertically mounted on the bottom of the lower seating portion 30a is connected to the lower end of the electromagnet block 50 so as to rotate to operate the shaft 40 about the shaft.

Next, the tilting means 70 is shown in FIGS. 3 to 5, and the tilting means 70 may tilt the remaining scrap S ′ fixed as the fixing means 50. 50 is rotatably mounted to the shaft 40 inwardly.

In addition, the tilting means 70 as described above is seated between the body 74 and the fixing means 50 through which the opening 72 through which the shaft 40 is inserted and supported is formed in the front, and the remaining steel sheet straps ( S ') is provided with a tilting plate 76 which is integrally formed to the rear of the body 74 so as to tilt the S').

In addition, the lower portion of the body 74 is connected to the second lifting cylinder 78 which is horizontally installed in the lower mounting portion 30a is connected to the steel sheet scrap 20 fixed on the fixing means 50 during the cylinder operation It is rotated to tilt.

On the other hand, the magnetic block 50 and the tilting means as the first and second sensors 80a installed at the lower part of the lower and lower mounting portion 30a at the lower portion of the magnet block 50 and the tilting means body 74 of the fixing means ( The first and second sensor plates 82a and 82b for sensing the rotational operation of the 70 are integrally formed.

In addition, the tilting plate 76 of the tilting means 70 is a third sensor 84a installed on one side of the upper part of the cutter 10 to reflect the presence of steel plate scrap S 'on the lower road 30 ( 84b) is installed, and the strap reservoir (90) for collecting the tilted steel scrap (S ') is provided in front of the lower road 30 is configured.

Referring to the operation and effects of the present invention made in the above configuration in more detail as follows.

As shown in FIGS. 3 to 6, when the defective portion of the steel sheet is cut before the welding operation of the preceding and subsequent steel sheets for the continuous operation of the cold rolled steel sheet, cutting of the other steel sheet by the abnormal steel sheet scrap (S ') Cutting strip tilting device (1) of the present invention to prevent the poor cutting of the steel sheet generated at the time is as follows.

First, as shown in Figure 3, the adjustment block 34, which is spring-loaded for the replacement or spacing of the upper and lower knife 22, 32 to substantially cut the steel plate in the cutter 10 is Connected to the knife, respectively, is located in the seating portion (30a) formed in front of the lower roadway 30, and eventually the device 1 of the present invention is installed in place of the adjustment block 34 in the lower roadway seating portion (30a).

That is, as shown in FIG. 5, the shaft 40 is inserted into the mounting groove 30b integrally formed in the longitudinal direction toward the lower road 30. In this case, the shaft 40 will be described in detail later. ) Is formed through the opening 52 formed in the magnetic block 50, which is the fixing means, and the opening 72 formed through the body 74 of the tilting means 70 seated inward of the magnetic block 50. It is mounted on (30), so that the fixing means (50) and the tilting means (70) are rotatable in the seating portion (30a) of the lower roadway (30) about the shaft (40).

3 to 5, the magnet block 50 formed of a square block to connect the shaft 40 and the fixing means, that is, in two stages through the opening 52 in detail in the drawings Although not described, it is formed of an electromagnet block.

Therefore, when the steel sheet scrap S 'remains on the undercoat knife 32 during the cutting operation of the steel sheet, the third sensor 84a installed on the upper side of the cutter 10 is moved to the tilting plate 76 of the tilting means 70. It is not operated as the reflecting plate 84b provided at the bottom end, so that the steel sheet scrap S 'remains on the undercoat knife 32. At this time, the third sensor 84a is provided through a control panel (not shown). The signal that there is a residual top scrap (S ') from turns on the electromagnet block.

As a result, as shown in Figure 6a, the steel sheet scrap (S ') is in a state of being closely fixed to the electromagnet block 50 that is a fixing means, and at the same time as shown in Figure 6b, the electromagnet block ( 50 is to raise the shaft 40 to the axis by the operation of the first lifting cylinder 56 connected to the lower, the reason why the electromagnet block 50 is fixed to the steel sheet scrap (S ') of the conventional tilting plate To prevent the steel sheet scraps from being rotated and falling into the inside of the cutter 10 during rotation.

That is, when the electromagnet block 50 is inclined to rotate, even if the steel sheet scrap (S ') is fixed to the upper portion of the lower knife 32 is prevented from falling into the cutter 10 during the next tilting operation It is.

Next, as shown in Figure 6c, the power supply of the electromagnet block 50 is short-circuit (OFF) and at the same time, the tilting means 70 supported by the shaft 40 in the shaft of the inside of the electromagnet block 50; Tilt plate 76 is lifted by the operation of the lower second lifting cylinder 78.

Therefore, the steel sheet scrap S 'which is inclined to the electromagnet block 50 is collected in the container 90 installed in front of the cutter 10 while being pushed by the rotation of the tilting plate 76.

At this time, the magnet block 50 is fixed to the shaft (40) bolts 54, the rotation of the magnetic block 50 is made in the tilting plate 76 is rotated in operation, as in the magnetic block 50 The tilting plate 76 is an integral body portion 74 is rotated about the shaft 40 shaft.

When the electromagnet block 50 rotates, when the first sensor plate 82a at the lower side moves to operate the first sensor 80a, the signal generated therein blocks the power of the magnet block and simultaneously lifts the second lifting unit. When the cylinder 78 is operated, and the tilting plate 70 rotates, the second sensor plate 82b is moved while the second sensor plate 82b installed below the tilting body 74 moves to operate the steel sheet scrap S '. Deviation of is detected and returns to the initial position.

In addition, as shown in Figure 6d, if the thickness of the steel sheet is thick, when the inclined state after the rotation of the electromagnet block 50, first, the power of the electrocutting block 50 is cut off the inclined steel sheet scrap ( After S ') slips to some extent, the tilting plate 76 is operated to be detached. In this case, the operation time is slightly delayed, but when the weight of the steel sheet is large, it can be effectively removed and removed.

Accordingly, as compared to removing the steel sheet scrap S 'by simply rotating the tilting plate in the related art, in the present design, the residual steel sheet scrap S' is almost completely automatically removed from the bottom surface by using the electromagnet block 50. This is to prevent the poor cutting by the cutter 10 in advance.

Thus, according to the cutting strip tilting device of the present invention, by removing the strap, which is the cutting steel sheet remaining on the lower part of the cutter part of the cutter part of the leading and trailing steel plates for welding work of the cold rolled steel sheet, to the outside of the cutter, By improving the production productivity of the cold rolled steel sheet by preventing the poor cutting of the steel sheet in advance, while having a simple structure using a magnetic, there is an excellent effect that is easy to manufacture and install the device.

While the invention has been shown and described with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various changes and modifications can be made without departing from the spirit or scope of the invention as set forth in the claims below. I would like to know that those who have knowledge of this can easily know.
