[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting a fixed-distance pusher, first rotate the second one-way screw according to the cutting length. The distance from the distance-adjusting slider to the center of the turntable is twice the distance that the movable plate pushes the steel structure to move once. Start the motor, and make the T-type piston rod reciprocate through the operation of the motor to push the aqueous solution inside the water tank into the liquid storage tank, so that the push plug rod drives the movable plate to move a certain distance toward the cutting machine. With the operation of the cutting machine, the fixed-length cutting of the steel structure can be achieved. The T-type piston rod repeatedly extracts the aqueous solution to make the push plug rod intermittently move the specified distance, so that the length of each section of the steel structure cut by the cutting machine is equal, which not only increases the application range of the equipment and improves the cutting efficiency, but also reduces the labor intensity of the staff; 2. By setting the clamping unit, after placing the steel structure on the workbench, one end of the steel structure is fitted with the movable plate, and then the bidirectional screw and the first unidirectional screw are rotated, and the side pressure plates are clamped and limited on both sides of the steel structure through the rotation, and at the same time, the upper pressure plate is clamped and limited on the top of one end of the steel structure through the rotation of the first unidirectional screw, and then the third unidirectional screw is rotated, and the limiting guide frame drives the movable plate to move toward the cutting groove through the rotation of the third unidirectional screw, so that the end of the steel structure away from the movable plate is aligned with the cutting groove, so that the equipment is suitable for steel structures of different lengths and widths, which not only increases the stability of the steel structure during cutting, but also improves the accuracy of the cutting distance; 3. By setting an intermittent movable part, when the second U-shaped frame moves toward the motor, the T-shaped piston rod moves away from the liquid injection bin. At this time, part of the aqueous solution inside the water tank enters the liquid injection bin. At the same time, the first U-shaped frame drives the diagonal pressure rod to move toward the water tank. In this process, the second baffle is blocked by the first baffle. At this time, the diagonal pressure rod will press the shift pin downward through the inclined surface, so that the cutting machine moves toward the cutting groove, thereby realizing the cutting of the steel structure. In this way, the steel structure and the cutting machine can be moved alternately, so that there is no need for the staff to manually operate the cutting machine, which further reduces the labor intensity of the staff.

A first one-way valve 631 is installed at one end of the liquid storage bin 629 away from the pushing frame 610, and a liquid injection bin 621 is installed at the bottom of the first one-way valve 631. The bottom of the liquid injection bin 621 is provided with a second one-way valve 631. The second one-way valve 634 is provided with a water tank 617 at the bottom end of the second one-way valve 634, a solenoid valve 635 is provided on the top of the water tank 617 and is located on one side of the second one-way valve 634, a discharge pipe 626 connected to the liquid storage bin 629 is provided on the solenoid valve 635, a motor 613 located below the liquid injection bin 621 is provided on the outer wall of the water tank 617, a reciprocating screw rod 611 is connected to the output end of the motor 613, a third guide rod 633 located below the reciprocating screw rod 611 is provided on the outer wall of the water tank 617, and a third guide rod 633 slidably connected to the third guide rod 633 is sleeved on the reciprocating screw rod 611. The outer wall of the second U-shaped frame 612, the water tank 617 is rotatably connected to the turntable 616 on one side away from the motor 613 through a rotating shaft, and a second transmission bevel gear 623 is installed at the bottom of the rotating shaft connecting the turntable 616 and the water tank 617. The outer wall of the water tank 617 is rotatably connected to the first transmission bevel gear 622 meshing with the second transmission bevel gear 623 through a rotating shaft, and transmission spur gears 615 are installed at both ends of the first transmission bevel gear 622. A shift rack 614 meshing with the transmission spur gear 615 is installed at one end of the second U-shaped frame 612 close to the water tank 617, and a top of the turntable 616 is provided. There is a second one-way screw rod 624, and a distance measuring rod 637 located on both sides of the second one-way screw rod 624 is installed on the top of the turntable 616. A distance adjusting slider 636 slidably connected to the distance measuring rod 637 is sleeved on the second one-way screw rod 624. A T-shaped piston rod 625 extending to the outside of the liquid filling bin 621 is inserted into the liquid filling bin 621, and a guide straight groove 638 is opened on the T-shaped piston rod 625. An eccentric pin 639 slidably connected to the guide straight groove 638 is installed on the top of the distance adjusting slider 636, and second return springs 619 connected to the liquid storage bin 629 are arranged on both sides of the push frame 610.

[0023] In this embodiment, before cutting the steel structure, the second one-way screw 624 is rotated according to the cutting length. The second one-way screw 624 is rotated to make the distance-adjusting slider 636 limited by the distance-measuring rod 637 move horizontally along the second one-way screw 624. At this time, the distance-adjusting slider 636 pulls the T-shaped piston rod 625 through the eccentric pin 639 and the guide straight groove 638. Then, the distance from the distance-adjusting slider 636 to the center of the rotating disk 616 is adjusted by observing the position on the distance-measuring rod 637 corresponding to the distance-adjusting slider 636. The distance between the slider 636 and the center of the turntable 616 is twice the distance that the movable plate 5 pushes the steel structure to move once. Then, the motor 613 is started, and the second U-shaped frame 612 is moved horizontally along the reciprocating screw 611 through the operation of the motor 613, so that the second U-shaped frame 612 drives the turntable 616 to rotate through the shift rack 614, the transmission spur gear 615, the first transmission bevel gear 622, and the second transmission bevel gear 623. When the T-shaped piston rod 625 moves away from the liquid injection bin 621 along with the distance adjustment slider 636, The T-shaped piston rod 625 will extract the aqueous solution inside the water tank 617 through the second one-way valve 634. When the T-shaped piston rod 625 moves toward the liquid injection bin 621, the T-shaped piston rod 625 will push the aqueous solution inside the liquid injection bin 621 into the liquid storage bin 629 through the first one-way valve 631, so that the push plug rod 632 drives the movable plate 5 to move a certain distance toward the cutting machine 4. With the operation of the cutting machine 4, the fixed-length cutting of the steel structure can be achieved. After that, the T-shaped piston rod 625 repeatedly extracts the aqueous solution to The push plug rod 632 is made to intermittently move a specified distance so that the length of each section of the steel structure cut by the cutting machine 4 is equal, which not only increases the application range of the equipment and improves the cutting efficiency, but also reduces the labor intensity of the staff. After the cutting of the steel structure is completed, the solenoid valve 635 is opened. At this time, the push frame 610, under the action of the elastic restoring force of the second return spring 619, enables the push plug rod 632 to push the aqueous solution inside the liquid storage tank 629 into the water tank 617 through the drain pipe 626, thereby restoring the push plug rod 632 to its initial position.

[0024] Please refer to Figure 5 , Figure 8 The zero scale line on the ranging rod 637 is aligned with the center of the turntable 616, and the inner wall diameters of the liquid injection tank 621 and the liquid storage tank 629 are equal.

[0025] In this embodiment: by setting this structure, the distance from the adjustable slider 636 to the center of the turntable 616 can be accurately adjusted, and at the same time, the distance moved by the push plug rod 632 when the T-shaped piston rod 625 injects the aqueous solution into the liquid storage tank 629 is twice the distance from the adjustable slider 636 to the center of the turntable 616.

[0026] Please refer to Figure 4 , Figure 5 The liquid inlet and liquid outlet of the first one-way valve 631 are connected to the liquid injection tank 621 and the liquid storage tank 629 respectively, and the liquid inlet and liquid outlet of the second one-way valve 634 are connected to the water tank 617 and the liquid injection tank 621 respectively.

[0027] In this embodiment: this structure is provided to realize the one-way flow of the aqueous solution inside the liquid injection tank 621 , so that the aqueous solution entering the liquid injection tank 621 enters the liquid storage tank 629 through the push of the T-shaped piston rod 625 .

[0028] Please refer to Figure 5 The length of the reciprocating screw rod 611 is equal to the length of the shift rack 614 , the circumference of the outer side of the transmission spur gear 615 is equal to the length of the shift rack 614 , and the diameter of the second transmission bevel gear 623 is twice the diameter of the first transmission bevel gear 622 .

[0029] In this embodiment: by setting this structure, when the reciprocating screw 611 drives the second U-shaped frame 612 to move toward the motor 613, the first transmission bevel gear 622 drives the second transmission bevel gear 623 to rotate one hundred and eighty degrees, so that when the reciprocating screw 611 drives the second U-shaped frame 612 to perform a reciprocating movement in the horizontal direction, the turntable 616 reciprocates one hundred and eighty degrees relative to the water tank 617.

[0030] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 The positioning unit includes a third one-way screw rod 627 rotatably connected to the inner side of the pushing frame 610 through a bearing, a limiting guide frame 620 extending to the outer side of the pushing frame 610 is sleeved on the third one-way screw rod 627, and the movable plate 5 is installed on the top of one end of the limiting guide frame 620, and a bidirectional screw rod 630 is installed on the side of the movable plate 5 away from the pair of cutting grooves 606, and a side pressure plate 618 extending to the side of the movable plate 5 away from the bidirectional screw rod 630 and slidably connected to the movable plate 5 is sleeved on the bidirectional screw rod 630, and a first one-way screw rod 601 is installed on the top of the movable plate 5, and a first guide rod 603 located on one side of the first one-way screw rod 601 is installed on the top of the movable plate 5, and an upper pressure plate 602 slidably connected to the first guide rod 603 is sleeved on the first one-way screw rod 601.

[0031] In this embodiment: after placing the steel structure on the workbench 1, one end of the steel structure is fitted with the movable plate 5, and then the bidirectional screw rod 630 and the first unidirectional screw rod 601 are rotated. The side pressure plate 618 is clamped and limited on both sides of the steel structure by the rotation of the bidirectional screw rod 630. At the same time, the upper pressure plate 602 is clamped and limited on the top of one end of the steel structure by the rotation of the first unidirectional screw rod 601. Then, the third unidirectional screw rod 627 is rotated. The limiting guide frame 620 drives the movable plate 5 to move toward the cutting groove 606 by the rotation of the third unidirectional screw rod 627, so that the end of the steel structure away from the movable plate 5 is aligned with the cutting groove 606, so that the equipment is suitable for steel structures of different lengths and widths, which not only increases the stability of the steel structure during cutting, but also improves the accuracy of the cutting distance.

[0032] Please refer to Figure 4 The pushing frame 610 is provided with a limiting groove which matches with the limiting guide frame 620 .

[0033] In this embodiment, this structure is provided to enable the pushing frame 610 to limit the limiting guide frame 620 in the horizontal direction, so that the limiting guide frame 620 can move stably relative to the pushing frame 610 .

[0034] Please refer to Figure 1 , Figure 6 , Figure 7 The intermittent movable part includes an extension plate 609 installed on the side of the second U-shaped frame 612 away from the shifting rack 614, and a first U-shaped frame 608 is installed at one end of the extension plate 609. Limiting rods 605 slidably connected to the movable frame 3 are arranged on both sides of the workbench 1. The top of the limiting rod 605 is provided with a first return spring 604 connected to the movable frame 3, and the bottom end of the movable frame 3 is provided with a shifting pin 607 located below the cutting groove 606. The inner side of the first U-shaped frame 608 is rotatably connected with an oblique pressure rod 642 through a rotating shaft, and a first baffle 640 is installed on the outer side of the first U-shaped frame 608. A second baffle 641 located below the first baffle 640 is installed at one end of the rotating shaft connecting the oblique pressure rod 642 and the first U-shaped frame 608, and a torsion spring 643 connected to the first U-shaped frame 608 is arranged on the outer side of the rotating shaft connecting the oblique pressure rod 642 and the first U-shaped frame 608.

[0035] In this embodiment: when the second U-shaped frame 612 moves toward the motor 613, the T-shaped piston rod 625 moves away from the liquid injection bin 621. At this time, part of the aqueous solution inside the water tank 617 enters the liquid injection bin 621. At the same time, the first U-shaped frame 608 drives the oblique pressure rod 642 to move toward the water tank 617. During this process, the second baffle 641 is blocked by the first baffle 640. At this time, the oblique pressure rod 642 will press the shift pin 607 downward through the oblique surface, so as to move the cutting machine 4 toward the cutting groove 606, thereby realizing the cutting of the steel structure. When the oblique pressure rod 642 is separated from the shift pin 607, the movable frame 3 will move to the initial position under the action of the elastic restoring force of the first reset spring 604. When the second U-shaped frame 612 moves away from the liquid injection bin 621, the first U-shaped frame 608 drives the oblique pressure rod 642 to move toward the water tank 617. During this process, the second baffle 641 is blocked by the first baffle 640. At this time, the oblique pressure rod 642 will press the shift pin 607 downward through the oblique surface, so as to realize the cutting machine 4. Move toward the cutting groove 606, thereby realizing the cutting of the steel structure. When the motor 613 moves, the T-shaped piston rod 625 squeezes the aqueous solution inside the liquid injection bin 621. At this time, the first U-shaped frame 608 drives the inclined pressure rod 642 to move toward the shift pin 607. At this time, since the bottom of the second baffle 641 is not blocked, the shift pin 607 can be made to contact the inclined pressure rod 642. As the inclined pressure rod 642 moves, the inclined pressure rod 642 rotates relative to the first U-shaped frame 608. When the shift pin 607 is separated from the inclined pressure rod 642, the inclined pressure rod 642 is restored under the action of the elastic restoring force of the torsion spring 643. In this way, the steel structure can be moved alternately and the cutting machine 4 can be moved alternately. There is no need for the staff to manually operate the cutting machine 4, which further reduces the labor intensity of the staff and improves the cutting accuracy.

[0036] Please refer to Figure 7 The horizontal height of the oblique pressure rod 642 away from the end of the first U-shaped frame 608 is less than the horizontal height of the oblique pressure rod 642 close to the end of the first U-shaped frame 608.

[0037] In this embodiment, this structure is provided to realize the unidirectional movement of the oblique pressure rod 642 to shift the shift pin 607 , and cooperate with the first return spring 604 to realize the up and down reciprocating movement of the cutting machine 4 .

[0038] In combination with the above-mentioned steel structure cutting device capable of fixed-length feeding, a steel structure cutting method capable of fixed-length feeding is provided, which specifically includes the following steps: S1: First start the cutting machine 4, then place the steel structure on the top of the workbench 1 so that it is located between the cutting groove 606 and the movable plate 5; S2: Then, the bidirectional screw rod 630 and the first unidirectional screw rod 601 are rotated, and the side pressure plate 618 is clamped and limited on both sides of the steel structure by the rotation of the bidirectional screw rod 630, and the upper pressure plate 602 is clamped and limited on the top of one end of the steel structure by the rotation of the first unidirectional screw rod 601, and then the third unidirectional screw rod 627 is rotated, and the limiting guide frame 620 drives the movable plate 5 to move toward the cutting groove 606 by the rotation of the third unidirectional screw rod 627, so that the end of the steel structure away from the movable plate 5 is aligned with the cutting groove 606; S3: Rotate the second one-way screw 624 according to the cutting length. The second one-way screw 624 is rotated to make the distance-adjusting slider 636 limited by the distance-measuring rod 637 move horizontally along the second one-way screw 624. At this time, the distance-adjusting slider 636 pulls the T-shaped piston rod 625 through the eccentric pin 639 and the guide straight groove 638. Then, the distance from the distance-adjusting slider 636 to the center of the rotating disk 616 is adjusted by observing the position of the distance-measuring rod 637 corresponding to the distance-adjusting slider 636. The distance between the slider 636 and the center of the turntable 616 is twice the distance that the movable plate 5 pushes the steel structure to move once. The motor 613 is started, and the second U-shaped frame 612 is moved horizontally along the reciprocating screw rod 611 through the operation of the motor 613, so that the second U-shaped frame 612 drives the turntable 616 to rotate through the shift rack 614, the transmission spur gear 615, the first transmission bevel gear 622, and the second transmission bevel gear 623. When the T-shaped piston rod 625 moves away from the distance adjustment slider 636, the second U-shaped frame 612 is rotated. When the liquid injection bin 621 moves, the T-shaped piston rod 625 will extract the aqueous solution inside the water tank 617 through the second one-way valve 634. When the T-shaped piston rod 625 moves toward the liquid injection bin 621, the T-shaped piston rod 625 will push the aqueous solution inside the liquid injection bin 621 into the liquid storage bin 629 through the first one-way valve 631, so that the push rod 632 drives the movable plate 5 to move a certain distance toward the cutting machine 4. When the second U-shaped frame 612 moves toward the motor 613, the movable plate 5 moves to the cutting machine 4. When the T-shaped piston rod 625 moves away from the liquid injection bin 621, part of the aqueous solution in the water tank 617 enters the liquid injection bin 621, and at the same time, the first U-shaped frame 608 drives the oblique pressure rod 642 to move toward the water tank 617. During this process, the second baffle 641 is blocked by the first baffle 640, and the oblique pressure rod 642 presses the shift pin 607 downward through the oblique surface, so that the cutting machine 4 moves toward the cutting groove 606, thereby realizing the cutting of the steel structure; S4: The T-shaped piston rod 625 repeatedly extracts the aqueous solution to make the push plug rod 632 intermittently move a specified distance, so that the length of each section of the steel structure cut by the cutting machine 4 is equal. After the cutting of the steel structure is completed, the solenoid valve 635 is opened. At this time, the push frame 610, under the action of the elastic restoring force of the second return spring 619, enables the push plug rod 632 to push the aqueous solution inside the liquid storage tank 629 into the water tank 617 through the drain pipe 626, so that the push plug rod 632 returns to its initial position.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
