Description

Technical Field

[0002] Thin-walled steel structure is a structure made of steel strips with various cross-sections processed by cold bending. During the production process, after a roll of steel strip is used up, the steel strip needs to be replaced to continue production, and the head and tail of the new and old steel strips need to be connected. On the one hand, it can avoid re-debugging the equipment, and on the other hand, it can reduce the waste of surplus materials. The traditional method of replacing steel strips is to manually pull the head of the replaced steel strip to the tail of the old steel strip, which is almost the connection part. Then use a cutting machine to cut the joints of the two rolls of steel strips flat. Finally, use carbon dioxide shielded welding to weld the joints together to complete the steel strip feeding process. However, the manually cut joints cannot guarantee neat seams, which will lead to wider welds in the subsequent welding, and the head and tail of the steel strip are prone to deformation in the manufacturing and production links. Manual feeding cannot be flattened and compacted, so in order to ensure the quality of the joints, a long part of the deformed parts will be cut off, resulting in serious material waste.

[0022] Specifically, Figure 7 and Figure 8As shown, the cutting device 6 includes a mounting frame 601 and a driving mechanism; a saw blade 602 and a chain 603 for cutting a steel strip are arranged in the mounting frame 601; two ends of the chain 603 are fixed relatively to two ends of the saw blade 602, and the chain 603 and the saw blade 602 can form a ring; a sprocket 604 for driving the chain 603 to work is also arranged in the mounting frame 601, and a motor 605 for driving the sprocket 604 to rotate is arranged outside the mounting frame 601; the driving mechanism is used to drive the mounting frame 601 to move on the equipment bracket 3 and adjust the inclination angle of the mounting frame 601 and the saw blade 602; the driving mechanism includes a slide 627 , the slide 627 is slidably connected to the equipment support 3, the mounting frame 601 is hinged to the slide 627, and a horizontal hydraulic cylinder 628 is fixedly connected to the slide 627 for driving it to move horizontally on the equipment support 3; a vertical hydraulic cylinder 629 is also hinged on the slide 627; the vertical hydraulic cylinder 629 is hinged to the mounting frame 601 at one end away from the slide 627, and is used to drive the mounting frame 601 to rotate and adjust the inclination angle of the saw blade 602; during operation, when it is necessary to cut the steel strip, the horizontal hydraulic cylinder 628 can drive the slide 627 and the mounting frame 601 to move on the slide rail 303, and then the vertical hydraulic cylinder 629 can drive the mounting frame 60 1 is rotated around the rotating shaft to adjust the inclination angle of the saw blade 602; the motor 605 can drive the sprocket wheel 604 to rotate back and forth, thereby driving the chain 603 and the saw blade 602 to move back and forth in the front and rear directions. The reciprocating movement of the saw blade 602 can cut the irregular parts of the head of the new steel strip and the tail of the old steel strip; after the cutting work is completed, the cutting device retreats to the outside of the fixed leveling device 4, and then the sliding leveling device 5 drives the head of the new steel strip to move to a position aligned with the tail of the old steel strip, and then the welding robot (not shown in the figure) arranged at the rear side of the equipment support 3 can weld the connection between the new and old steel strips; after the welding of the new and old steel strips is completed, the sliding leveling device 5 is used to move the head of the new steel strip to the position aligned with the tail of the old steel strip.

[0023] Specifically, Figure 8 and Fig. 9As shown, a tensioning wheel 606 capable of transmitting with the chain 603 is installed in the installation frame 601, and a first slider 607 is rotatably installed on the tensioning wheel 606, and the first slider 607 is elastically slidably connected to the installation frame 601; a locking rod 608 and a driving assembly are arranged on the side of the first slider 607; the driving mechanism can drive the locking rod 608 to lock the first slider 607 when the saw blade 602 is working, so that the first slider 607 is relatively fixed to the installation frame 601; the driving assembly includes a first pulley 609; the first pulley 609 is fixedly installed on the rotating shaft of the sprocket 604, and is connected to the second pulley 611 through a transmission belt 610, and the second pulley 611 is fixed on the rotating shaft A first gear 612 is connected, the first gear 612 is rotatably connected to the installation frame 601, the first gear 612 is meshed with a first rack rod 613, the first rack rod 613 is slidably connected to the installation frame 601, one end of the first rack rod 613 is hinged with a connecting rod 614, a turntable 615 is provided on the side of the connecting rod 614 away from the first rack rod 613, and one end of the connecting rod 614 away from the first rack rod 613 is hinged at a non-center position on the turntable 615; a second gear 616 is fixedly connected to the rotating shaft of the turntable 615, the second gear 616 is rotatably connected to the installation frame 601, the second gear 616 is meshed with a second rack rod 617, and the second rack rod 617 is fixedly connected to the locking rod 608.

[0024] When working, the sprocket 604 can drive the first gear 612 to rotate through the first pulley 609, the transmission belt 610 and the second pulley 611; since the sprocket 604 reciprocates within a certain angle, the first gear 612 will drive the first rack rod 613 to reciprocate, and the first rack rod 613 can drive the rotating disk 615 to rotate through the connecting rod 614, and the rotating disk 615 can drive the second rack rod 617 to move toward the side close to the first slider 607 through the second gear 616, and the second rack rod 617 can drive the locking rod 608 to move synchronously, and the locking rod 608 can squeeze the first slider 607. The first slider 607 is fixed; the present invention uses the setting of the tensioning wheel 606, the first slider 607, the locking rod 608 and the driving assembly. When the sprocket 604 drives the chain 603 and the saw blade 602 to perform cutting work, the driving assembly can drive the locking rod 608 to lock the first slider 607, so that the first slider 607 remains fixed, the tensioning wheel 606 will not move when the saw blade is working, and the saw blade 602 can perform cutting work stably; when the saw blade 602 stops working, the locking rod 608 cancels the locking of the first slider 607, and the tensioning wheel 606 can move freely, which can greatly reduce the difficulty of replacing the saw blade 602.

[0025] Specifically, Figure 8 As shown, the locking rod 608 is a telescopic rod, and a return spring is installed inside; setting the locking rod 608 as a telescopic rod can make the locking rod 608 better squeeze the first slider 607, so that the tensioning wheel 606 can be better fixed.

[0026] Specifically, Figure 8 , Fig.10 and Fig.11 As shown, both ends of the saw blade 602 are relatively fixed to the two ends of the chain 603 through connectors; the connector includes a mounting head 618, which is welded to the end of the chain 603 and is slidably connected to the mounting frame 601; a card slot 619 for mounting the saw blade 602 is provided on the inner side of the mounting head 618, and a card block 620 is elastically slidably connected to the mounting head 618, and the card block 620 can be plugged into the mounting holes at both ends of the saw blade 602; a push rod 621 is provided on the outer side of the card block 620, and the push rod 621 is provided on the outer side of the card block 620.

[0027] During operation, the locking rod 608 moves toward the side close to the first slider 607. When the first slider 607 is locked, the locking rod 608 drives the connecting frame 624 to move upward through the second traction rope 625, and the connecting frame 624 drives the second slider 623 to move upward synchronously. The second slider 623 drives the push rod 621 to move toward the side close to the installation frame 601 through the first traction rope 623, and the push rod 621 pushes the block 620 to move toward the side close to the saw blade 602, and the block 620 presses the saw blade. 602, making the saw blade 602 more stable when working; when the saw blade 602 stops working, the block 620 will retreat outward under the action of the spring. When the saw blade 602 needs to be replaced, the staff only needs to pull the saw blade 602 out of the slot 619, and then install the new saw blade into the slot 619, so the difficulty of disassembling and installing the saw blade 602 can be greatly reduced; the round head of the block 620 close to the slot 619 can ensure that the saw blade 602 will not fall out of the slot 619 when not working.

[0028] Specifically, Fig.11 As shown, the clamping block 620 is also fixedly connected to a pressing block 626 made of rubber material; through the setting of the pressing block 626, when the saw blade 602 is working, the clamping block 620 can cooperate with the pressing block 626 to better fix the saw blade 602.

[0029] Specifically, Figure 8 As shown, the end of the locking rod 608 close to the first slider 607 is made of rubber material; setting one end of the locking rod 608 to be made of rubber material can make the friction between the contact surface of the locking rod 608 and the first slider 607 greater, and can better lock the first slider.
