Description

Corrugated steel sheet manufacturing apparatus {A MANUFACTURING DEVICE FOR CORRUGATED STEEL STRUCTURAL PLATE}

The present invention relates to an apparatus for producing corrugated steel sheet, and in particular, by fully conveying and bending the corrugated steel sheet in the transverse direction to realize fully automation of the corrugated steel sheet manufacturing process, while forming a complete curvature using a roller in the bending operation This is to prevent the load carrying capacity of the corrugated steel pipe from being reduced.

In general, corrugated steel sheet is a waveform formed on a steel sheet, the load and reaction force is uniformly distributed throughout the steel sheet due to the waveform has a feature of large load capacity. These corrugated steel sheets can be used for the purpose of the plates by connecting them to each other by overlapping or bolting, or giving the curvature to the corrugated steel sheets and connecting them to each other.

Since the structure made of corrugated steel sheet is more economical than other rigid culverts, it is used for culverts such as underground passageways or water / drainage passages crossing highways or railways. Structures made of corrugated steel pipes are easy to transport and assemble in addition to the use of culverts. It is widely used for water, construction roofs, conveyor covers, and other simple structures.

Meanwhile, a conventional manufacturing method for manufacturing the corrugated steel sheet as described above will be introduced with reference to the block diagram of FIG. 1.

This method comprises: a flat steel sheet conveying step (P1) for conveying a flat steel sheet; A waveform shaping process (P2) for shaping the waveform on the transferred steel sheet; Hole forming step (P3) for drilling a bolt fastening hole in the steel plate is formed of a wave; It consists of a bending process (P4) to give a certain curvature to the steel sheet is formed of a waveform and holes.

This conventional corrugated steel sheet manufacturing method is shown as a block diagram, because the conventional operation was performed as an independent device in each process, and the movement between the processes was performed manually because it was not automated in moving to the next window. to be.

Here, the waveform shaping step (P2) is provided with a mold having a waveform of 1 or 2 pitches is formed in the pressing device in the horizontal direction up and down, inserting a steel sheet between the molds and then pressing the upper mold by the pressing device. Form corrugations on the steel sheet by 1 or 2 pitches. The steel sheet is then advanced in the longitudinal direction by a distance equal to one or two pitches, followed by forming one or two pitches of the waveform into the steel sheet with a mold. Therefore, in this corrugation molding step P2, dozens of corrugations are formed on one steel sheet in the longitudinal direction.

Next, in the hole forming step P3, holes for fastening bolts are formed at the edges of the steel plate in order to connect the corrugated steel sheets to the bolted joints. In this hole forming step P3, a hole or a peak of the steel sheet is formed using a punch. A plurality of holes are formed in each.

Thus, the corrugated steel sheet and the shape of the hole is used to manufacture the structure by fastening each hole of the plurality of steel plates with bolts. Therefore, in the case of manufacturing a simple steel plate structure, all the processes are completed in the hole forming step (P3).

On the other hand, when manufacturing a tube using a steel plate formed with a wave form to give a curvature to the steel sheet to form a tube when connected to each other.

Therefore, in the bending step P4, the mold having the corrugated shape is fixed to the upper and lower sides of the bending device, and the side surface of the steel sheet is fixed to protrude outward by a predetermined distance to the outside of the mold between the molds, and the protruding portion is hoisted. By pulling in to form a bend of 1 pitch. Subsequently, the steel sheet is pulled out one pitch to the outside of the mold, and then the corrugated steel sheet is pulled again with a hoist to form another one pitch pitch. By repeating this process, the entire corrugated steel sheet has a curvature, thereby producing corrugated steel sheets for canning.

On the other hand, when looking at the conventional corrugated steel sheet manufacturing process, it can be seen that not all the processes can work continuously in one line.

This is because the corrugated steel sheet must be inserted into the mold in the transverse direction and pulled by the hoist because the corrugated steel sheet is formed perpendicular to the traveling direction of the steel sheet. Therefore, turn the corrugated steel sheet at 90 ° from the corrugated line and insert the steel sheet into the bending device fixed to the mold, or place the bending device on the lateral direction of the corrugated line forming the steel plate and transfer the steel sheet laterally. Because you have to.

For this reason, in the conventional corrugated steel sheet manufacturing method, since the corrugated steel sheet and the shaped steel sheet are transferred to the bending process (P4), a separate conveying means must be passed, and thus, the entire process cannot be automated.

In the conventional corrugated steel sheet manufacturing method, the steel sheet is fixed between the molds fixed to the bending apparatus when bending the steel sheet having the corrugation, and the steel sheet is pulled and bent by a hoist, so that the plane of the predetermined pitch is continuously bent to form an overall arc shape. In part, it does not have complete curvature. In particular, it is impossible to form curvature at both ends of the steel sheet. Therefore, when the steel pipe is manufactured from such a steel sheet, it does not have a perfect circular shape, and thus there is a problem in that the load capacity is reduced as compared with the steel pipe having a complete curvature.

The present invention was devised to improve the conventional problems, and the object of the present invention is to realize a fully automated process of manufacturing a corrugated steel sheet by continuously conveying and bending a corrugated steel sheet in the transverse direction, while rollers in the bending operation By forming a complete curvature using the to prevent the load capacity of corrugated steel pipe is reduced.

Next, the flat plate feed process (P200) for operating the flat plate feeder 200 to transfer the flat steel plate 100 will be described.

The first first lifting motor 230 is rotated to lower the first lifting frame 234 through the first switching unit 232, and the vacuum suction device 238 is operated to form the steel sheet 100 using the vacuum suction plate 236. The first grip step (S201) for adsorbing is carried out.

In this case, when the first lifting motor 230 is rotated, the rotational force of the first lifting motor 230 is switched to a vertical feed force through the first switching unit 232 to lower the first lifting frame 234. Each vacuum suction plate 236 installed on the elevating frame 234 is brought into contact with the steel plate 100, and the vacuum suction input of the vacuum suction device 238 is transmitted to the vacuum suction plate 236 so that the vacuum suction plate 236 is moved to the steel plate ( 100).

Subsequently, a first lifting step S202 is performed in which the first lifting motor 230 is rotated in reverse to raise the first lifting frame 234 through the first switching unit 232.

Here, the first lifting motor 230 is rotated in reverse, the rotational force is to switch the vertical feed force through the first switching unit 232 to raise the first lifting frame 234, the first lifting frame 234 is raised As a result, the vacuum adsorption plate 236 fixed to the steel plate 100 to adsorb the steel plate 100 raises the steel plate 100.

As described above, when the lifting of the first elevating frame 234 is completed, the first conveying step 203 rotates the first conveying motor 224 to convey the first conveying member 220 along the first conveying rail 210 (S203). ) Proceeds.

When the transfer of the first conveying member 220 is completed as described above, the first seating step S204 of reducing the suction force of the vacuum suction device 238 to seat the steel plate 100 on the first conveying table 310 proceeds. do.

In this case, when the vacuum suction input of the vacuum suction device 238 is reduced, the vacuum suction plate 236 lays the steel plate 100, and the steel plate 100 is seated on the first carriage 310.

As described above, when the steel plate 100 is seated on the first conveyance table 310, the conveying body returning step (S205) of rotating the first conveying motor 224 to convey the first conveying member 220 to the first position. Proceeds.

In this case, the first transfer motor 224 reversely rotates and the first drive unit 222 reversely rotates, so that the first transfer member 220 moves to the first position along the first transfer rail 210 and again returns to the steel sheet ( 100) can be gripped.

The flat plate transfer process (P200) is a continuous operation is made by each step is repeated.

Next, the waveform and hole forming process P300 for forming the waveform and bolt fastening holes in the steel plate 100 by operating the waveform and hole forming apparatus 300 will be described.

First, both sides of the steel plate 100 are guided by using the side guides 318 to prevent side flow of the steel plate 100 seated on the first transfer table 310.

In this state, the first feeding step 301 is performed to rotate the first feeding motor 316 to transfer the steel plate 100 by one pitch through the first feeding unit 314.

In this case, the first feeding motor 316 is driven to rotate the pitch adjusting gear 326, and the stopper cylinder 322 is operated to brake the teeth 328 of the pitch adjusting gear 326 with the tip 324. As the one feeding unit 314 is driven by one pitch, the steel plate 100 is transferred to the pressing device 330 by one pitch. At this time, since the bracket 320 is installed in the first feeding unit 314, the rear end of the steel sheet 100 is pushed, so that the steel sheet 100 is well conveyed.

At the same time, by operating the pressure cylinder 336 of the pressurizing device 330 to raise and lower the flow frame 334, the waveform shaping step (S302) of forming a waveform on the steel sheet 100 with a mold 338 is performed.

Here, as the pressure cylinder 336 is operated to press the flow frame 334 upwards and downwards, the mold 338 fixed to the flow frame 334 presses the steel plate 100 to form a waveform of one pitch, Raise the flow frame 334 again.

Subsequently, the hole molding step S303 of forming the hole in the steel sheet 100 with the punch 342 by operating the punching cylinder 340 while simultaneously lifting and lowering the mold 338 by reactivating the pressure cylinder 336. .

Here, the pressure cylinder 336 is operated to pressurize the flow frame 334 again to form a wave shape formed in the steel sheet 100 more completely, and then operate the punching cylinder 340 to drive the punch 342 into the mold 338. By passing through the hole in the steel sheet 100. Then, the pressure cylinder 336 and the punching cylinder 340 are raised.

When the corrugation and the hole are formed in the steel sheet 100 as described above, the second feeding motor 364 rotates to transfer the steel sheet 100 on the second conveyance table 360 through the second feeding unit 362. The transfer step (S304) proceeds.

In this case, the second feeding motor 364 is rotated to move the second feeding unit 362 to transfer the steel plate 100 having the corrugated shape and the hole formed on the second carrier table 360 and installed on the fixed frame 332. The guide roller 350 prevents the upward flow of the steel sheet 100 passed between the pair of molds 338.

The waveform and hole molding process (P300) is a continuous operation is performed by each step is repeated.

Next, the transverse conveying process (P400) for operating the transverse conveying device 400 to convey the steel plate 100 in the transverse direction will be described.

Subsequent to the second transfer step S304, a first transfer detection step S401 for detecting the transfer of the steel plate 100 through the first limit switch 370 installed in the second transfer table 360 is performed.

In this case, the first limit switch 370 is connected to the first limit switch 370 provided at the upper end of the second conveyance table 360 by the steel sheet 100 transferred by the second feeding unit 362. The transfer completion of 100) is detected.

As such, when the transfer completion of the steel sheet 100 is detected, the feed roller 420 is raised by rotating the second lifting motor 412 to raise the second lifting frame 416 through the second switching unit 414. The roller raising step S402 is performed.

In this case, when the second lifting motor 412 is rotated, the rotational force of the second lifting motor 412 is switched to the vertical feed force through the second switching unit 414 to raise the second lifting frame 416. The feed roller 420 installed on the second elevating frame 416 rises to support the steel plate 100.

Subsequently, the horizontal transfer step S403 of transferring the steel plate 100 to the third transfer table 430 by rotating the transfer roller 420 by rotating the second transfer motor 422 is performed.

In this case, the second feed motor 422 is rotated to rotate the feed roller 420, so that the steel plate 100 is transferred in a direction orthogonal to the direction traveling in the second feed table 360, and thus the third feed table 430. Will be moved to.

When the steel sheet 100 is transferred to the third transfer table 430 as described above, the second transfer for detecting the transfer of the steel sheet 100 at the start switch 440 as the steel sheet 100 contacts the sensing bar 442. The detection step S404 is performed.

Subsequently, a third transfer step S405 of rotating the third feeding motor 434 to transfer the steel plate 100 on the third transfer table 430 through the third feeding unit 432 is performed.

Here, the third feeding unit 432 is moved by rotating the third feeding motor 434 in the control device by the signal of the start switch 440, so that the third feeding unit 432 moves from the feed roller 420. Moved to transport the steel sheet 100 seated on the third conveying table (430).

Then, the roller lowering step (S406) for lowering the feed roller 420 is performed by lowering the second lifting frame 416 through the second switching unit 414 by reversely rotating the second lifting motor 412.

In this case, when the second elevating motor 412 is reversely rotated, the rotational force of the second elevating motor 412 is switched to the vertical feed force through the second switching unit 414 to lower the second elevating frame 416. , The feed roller 420 installed in the second lifting frame 416 is lowered.

This transverse transfer process (P400) is a continuous operation is made by repeating each step.

Next, the selection process (P500) for selecting whether to bend the steel sheet 100 will be described.

After the third transfer step S405, a third transfer detection step S501 for detecting the transfer of the steel plate 100 by the second limit switch 510 is performed.

In this case, the transfer of the steel sheet 100 is sensed as the steel sheet 100, which is transferred on the third transfer unit 430 by the third feeding unit 432, contacts the second limit switch 510.

Subsequently, a determination step (S502) of determining whether the steel sheet 100 is bent is performed according to the contents input to the control device.

As a result of the determination in the determination step (S502), if bending is necessary, the continuous feeding step (S503) for continuously conveying the third feeding unit 432 by continuously rotating the third feeding motor 434 proceeds.

In this case, since the third feeding unit 432 is not stopped even when the transfer of the steel sheet 100 is detected by the second limit switch 510, the steel sheet 100 uses the first waveform roller (3) through the third feeding unit 432. It is conveyed below 732, and pushes and advances the rotation plate 718 of the feeding rod 716. At this time, the pivoting plate 718 rotates forward so that the rotation of the steel plate 100 is not hindered. Therefore, the steel plate 100 passes through the feeding rod 716 so that the rotating plate 718 is located at the rear end of the steel plate 100.

However, if bending is not necessary as a result of the determination in step S502, a stop step 504 of stopping the third feeding motor 434 to stop the third feeding unit 432 is performed.

In this case, when the size of the steel sheet 100 previously input is the smallest, the third feeding motor 434 is stopped by the control device by the signal of the first second limit switch 510 to stop the third feeding unit 432. When the size of the steel sheet 100 is slightly larger, the third feeding motor 434 is stopped by the control device by the signal of the second second limit switch 510 to stop the third feeding unit 432. .

When the size of the steel sheet 100 previously input is a little larger than the above case, the third feeding motor 434 is stopped by the control device by the signal of the third second limit switch 510, and the third feeding unit is stopped. When the size of the steel plate 100 is the largest, the third feeding motor 434 is stopped by the control device in response to the signal of the fourth second limit switch 510 to stop the third feeding unit 432. Stop).

As such, changing the stop position according to the size of the steel sheet 100, the magnetic unit 640 is located at the exact center of gravity of the steel sheet 100 to prevent the steel sheet 100 from tilting when the steel sheet 100 is gripped It is to.

Each step of the selection process (P500) is made for each transfer of the steel sheet (100).

Next, the discharge process (P600) for discharging the steel plate 100 through the discharge device 600 when not bending the steel plate 100 will be described.

When the steel plate 100 is stopped by the start switch 440 in the stop step (S504), the third lifting motor 630 is rotated to move the third lifting frame 634 through the third switching unit 632. The second grip step S601 of descending and operating the magnetic unit 640 to magnetically bond the steel sheet 100 is performed.

In this case, the second lifting motor 412 is rotated and its rotational force is switched to the vertical feed force through the third switching unit 632 to lower the third lifting frame 634, and the magnetic unit 640 operates to generate magnetic force. When the third lifting frame 634 is lowered in the generated state and the magnetic unit 640 contacts the steel plate 100, the steel plate 100 is bonded by the magnetic force of the magnetic unit 640. At this time, the waveform formed on the magnetic unit 640 coincides with the waveform of the steel sheet 100 so that the steel sheet 100 is well bonded.

Subsequently, a second lifting step S602 of rotating the third lifting motor 630 to raise the third lifting frame 634 through the third switching unit 632 is performed.

Here, the second lifting motor 412 is rotated in reverse, the rotational force is switched to the vertical feed force through the third switching unit 632 to lift the third lifting frame 634, fixed to the third lifting frame 634 The steel sheet 100 is magnetically bonded to the magnetic unit 640 is lifted.

When the lifting of the third lifting frame 634 is completed as described above, the second driving unit 620 operates to transfer the transfer frame 622 along the guide rails 612 of the third support frame 610. The transfer step (S603) proceeds.

Here, the second drive unit 620 is operated to move along the guide rail 612, whereby the transfer frame 622 supported by the second drive unit 620 and the third lifting frame 634 and the magnetic unit installed therein. 640, and the steel plate 100 is moved.

When the transfer of the transfer frame 622 is completed in this manner, the second mounting step (S604) of mounting the steel plate 100 on the carrier 660 by reducing the magnetic force of the magnetic unit 640 is performed.

In this case, when the magnetic force of the magnetic unit 640 is reduced, the steel plate 100 is separated from the magnetic unit 640 by its own load and is seated on the carrier 660.

As described above, when the steel plate 100 is seated on the carrier 660, the transfer frame return step S605 of operating the second driving unit 620 to return the transfer frame 622 is performed.

Here, the second drive unit 620 is operated to move along the guide rail 612, whereby the transfer frame 622 supported by the second drive unit 620 and the third lifting frame 634 and the magnetic unit installed therein. 640 moves to the first position, and the steel sheet 100 can be bonded again.

Subsequently, the third transfer motor 670 is rotated to rotate the pull chain 676 through the driving pulley 672 to transfer the carrier 660 on which the steel sheet 100 is seated along the second transfer rail 650. 5, the transfer step (S606) proceeds.

In this case, the steel plate 100 proceeds to flow out, and as the third transfer motor 670 rotates the driving pulley 672, the pulling chain 676 is inverted in the driven pulley 674 and the carrier 660. Moves along the second transfer rail 650. When the carrier 660 is transferred to the end of the second transfer rail 650, the front end of the carrier 660 contacts the stopper bracket 652 to stop.

When the steel plate 100 is separated from the carrier 660, the third transfer motor 670 is rotated in reverse to rotate the pulling chain 674 through the driving pulley 672 to rotate the carrier 660 in the second transfer rail. Carrier return step (S607) for transferring to the initial position along 650 proceeds.

Here, as the third transfer motor 670 reversely rotates the driving pulley 672, the pulling chain 676 is inverted in the driven pulley 674 and the carrier 660 is first moved along the second transfer rail 650. By moving to a position, it becomes a state which can seat a new steel plate 100.

The discharge process (P600) is a continuous operation is made by repeating each step.

Finally, when the steel sheet 100 is bent, a bending process P700 for forming a curvature in the steel sheet 100 by operating the bending apparatus 700 will be described.

In this case, when the fourth feeding motor 712 is rotated, the rotational force is switched to the horizontal feed force through the third switching unit 714 to transfer the feeding rod 716 in the horizontal direction, and installed at the front end of the feeding rod 716. The rotating plate 718 pushes the rear end of the steel plate 100 to push the steel plate 100 downward of the first waveform roller 732.

When the steel sheet 100 is supplied in this way, the pair of first lifting cylinders 742, the second lifting cylinders 752, and the third lifting cylinders 762 are operated to operate the second waveform roller 740 and the third, respectively.
