Description

Technical Field

[0001] The invention relates to the technical field of steel bar cutting, in particular to steel bar cutting equipment for building construction. Background Art

[0002] Rebar refers to steel used for reinforced concrete and prestressed reinforced concrete. Its cross section is round, sometimes square with rounded corners. It includes plain round steel bars, ribbed steel bars, and twisted steel bars. Rebars mainly bear tensile stress in concrete. Deformed steel bars have greater bonding ability with concrete due to the effect of ribs, so they can better withstand external forces. Rebars are widely used in various building structures. Especially large, heavy, light thin-walled and high-rise building structures.

[0003] When cutting steel bars, for steel bars of different lengths, first measure the length of the steel bars, and then use a steel bar cutting machine to cut them. When cutting, workers are required to fix the steel bars to be cut to prevent the vibration of the cutting from causing the steel bars to shift and cause errors.

[0004] During cutting, the workers hold the steel bars by hand to fix them. During the cutting process, the workers need to use great strength to hold the steel bars, which is laborious and dangerous. It is not easy to accurately grasp the cutting length, is not easy to operate, has poor applicability, and can only cut one steel bar at a time. After the steel bars are cut, they cannot be quickly cleaned and transported, which is not convenient for cutting the next group of steel bars. The cutting efficiency is low. At the same time, when the workers hold the steel bars by hand during the cutting process, they are close to the cutting point, and the dust generated during cutting can easily affect the health of the workers. They are prone to pneumoconiosis after long-term work. In addition, the existing steel bar cutting device will generate waste chips during cutting.

[0040] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0041] The following describes an embodiment of the present invention based on its overall structure.

[0042] like Figures 1 to 9As shown, the present invention provides a steel bar cutting device for construction, including an operating table 100, the top of the operating table 100 is connected to a fixing mechanism 200, the top of the operating table 100 is connected to a feeding mechanism 400, and the top of the operating table 100 is connected to an adjusting mechanism 500; the fixing mechanism 200 includes a positioning frame 210 connected to the top of the operating table 100, the inner wall of the positioning frame 210 is slidably connected to a clamping assembly 220, and the top of the clamping assembly 220 is attached to A push block 230 is provided, one side of the push block 230 is connected to a push assembly 240, the top of the push assembly 240 is connected to a lifting block 250, the top of the lifting block 250 is connected to a cutting mechanism 600, a positioning plate 260 is provided below the positioning frame 210, a positioning groove 270 is provided on the positioning plate 260, the positioning plate 260 is connected to the operating table 100, and a dust removal mechanism 300 is provided on the positioning plate 260; the clamping assembly 220 includes a positioning frame 210 and a positioning frame 210. The movable column 221 is slidably connected to the inner wall, and the bottom end of the movable column 221 is connected to a clamping plate 222, and the top end of the clamping plate 222 is connected to a top plate 223, and the top end of the top plate 223 is in contact with the push block 230. The outer wall of the movable column 221 is sleeved with a first spring 224, and the top end of the first spring 224 is connected to the top plate 223, and the bottom end of the first spring 224 is connected to the positioning frame 210. The clamping assembly 220, the push block 230, the positioning plate 260 and the positioning groove 270 are all provided with six groups; the pushing assembly 240 includes a first connecting rod 241 connected to the outer wall of the push block 230, The inner wall of the first connecting rod 241 is rotatably connected to the first connecting shaft 242, the outer wall of the first connecting shaft 242 is connected to the U-shaped plate 243, one side of the U-shaped plate 243 is connected to the rotating rod 244, the inner wall of the rotating rod 244 is rotatably connected to the second connecting shaft 245, the outer wall of the second connecting shaft 245 is connected to the second connecting rod 246, the top end of the second connecting rod 246 is connected to the lifting block 250, the bottom end of the rotating rod 244 is connected to the third connecting rod 247, the bottom end of the third connecting rod 247 is connected to the pushing block 230, and the pushing assembly 240 is provided with two groups.

[0043] Before cutting, the steel bar is placed in the groove of the positioning groove 270. When the adjustment mechanism 500 cuts the steel bar, the lifting block 250 is driven to move downward, thereby driving the second connecting rod 246 to move downward, and then driving the second connecting shaft 245 to move downward. The second connecting shaft 245 drives the rotating rod 244 to move downward, thereby driving the U-shaped plate 243 to move downward, and then driving the first connecting shaft 242 to move downward. The first connecting shaft 242 drives the first connecting rod 241 to move downward, thereby driving the push block 230 to approach the top plate 223 and fit the top plate 223 to push the top plate 223 to move downward, and then driving the moving column 221 to move downward. The moving column 221 drives the clamping plate 222 to approach the steel bar in the positioning groove 270 and fit the steel bar, clamping the steel bar between the positioning plate 260 and the clamping plate 222 to fix the steel bar. Since multiple groups of steel bars need to be fixed at the same time, six groups of clamping plates 222 move toward the steel bar at the same time to fix the steel bar. The rotating rod 244 can rotate with the second connecting shaft 245 as the axis. When the heights of the corresponding splints 222 under a group of push blocks 230 connected by the third connecting rod 247 and the two groups of push blocks 230 connected by the U-shaped plate 243 are inconsistent, the push blocks 230 drive the rotating rod 244 to rotate with the second connecting shaft 245 as the axis; when the heights of the corresponding splints 222 under the two groups of push blocks 230 connected at both ends of the first connecting rod 241 are inconsistent; the first connecting rod 241 can rotate with the first connecting shaft 242 as the axis, so that multiple groups of splints 222 can fix and clamp multiple groups of steel bars of different thicknesses at the same time under the drive of the pushing assembly 240, without the need to manually fix the steel bars.

[0044] Please refer to Figure 5 and Figure 6The feeding mechanism 400 includes a support frame 410 connected to the operating table 100, the outer wall of the support frame 410 is slidably connected to a moving block 420, the inner wall of the moving block 420 is rotatably connected to a rotating shaft 440, the outer wall of the rotating shaft 440 is connected to a feeding assembly 450, and the feeding assembly 450 is provided with six groups, one end of the rotating shaft 440 is connected to the output end of a servo motor 460, the bottom end of the rotating shaft 440 is connected to the telescopic end of an electric push rod 430, the electric push rod 430 is connected to the support frame 410, and the support frame 410 and the moving block 420 are each provided with two groups. The feeding assembly 450 includes a round block 451 connected to the outer wall of the rotating shaft 440, and a give-way groove 452 is opened on the round block 451. A second spring 453 is connected to the groove of the give-way groove 452, and one end of the second spring 453 is connected to a slide rod 454. The slide rod 454 is slidably connected to the give-way groove 452, and one end of the slide rod 454 is connected to an arc plate 455. The give-way groove 452, the second spring 453, the slide rod 454 and the arc plate 455 are each provided in four groups, and the four groups of the give-way groove 452, the second spring 453, the slide rod 454 and the arc plate 455 are arranged in a circular array with the rotating shaft 440 as the axis.

[0045] The servo motor 460 is started to drive the rotating shaft 440 to rotate, thereby driving the feeding assembly 450 to rotate. The rotation of the feeding assembly 450 can drive the steel bars below to move, thereby completing the transmission of the steel bars. The contact surface between the arc plate 455 and the steel bars is a rubber material with anti-slip grooves, which can increase the friction when contacting the steel bars, thereby driving the steel bars to move. When transmitting different steel bars, the slide bar 454 can slide in the yielding groove 452, thereby driving the arc plate 455 to approach or move away from the center of the circle 451. 53 is always in a compressed state, and the force of the second spring 453 to reset itself pushes the arc plate 455 to always fit the steel bar, so that when the shaft 440 rotates, the steel bar fitted by the arc plate 455 is driven to move and transport, and the electric push rod 430 is started, thereby driving the moving block 420 to adjust the height, and then driving the shaft 440 to adjust the height. The height of the shaft 440 can be adjusted according to the size of the steel bar to change the initial height of the arc plate 455, so that the arc plate 455 can fit and move the steel bars within a certain size range.

[0046] Please refer to Figures 7 to 9The adjustment mechanism 500 includes a support frame 510 connected to the top of the operating table 100, a limiting groove 520 is provided on the support frame 510, a slider 530 is slidably connected in the limiting groove 520, a threaded rod 550 is threadedly sleeved on the inner wall of the slider 530, the threaded rod 550 is rotatably connected to the support frame 510, an indicator needle 560 is connected to the bottom end of the slider 530, an indicator mark 570 is provided on one side of the support frame 510, a rotating assembly 580 is connected to one side of the support frame 510, and an adjustment assembly 540 is connected to one side of the slider 530. The support frame 510, the limiting groove 520 and the slider 530 are all provided with There are two groups, the two groups of support frames 510, limit grooves 520 and sliders 530 are symmetrically arranged on both sides of the adjustment component 540, and a steel bar collection box 700 is arranged below the adjustment component 540; the adjustment component 540 includes a rotating shaft 541 connected to one side of the slider 530, the outer wall of the rotating shaft 541 is rotatably connected to a rotating plate 542, the inner wall of the rotating plate 542 is connected to a moving shaft 543, and the outer wall of the moving shaft 543 is rotatably connected to a pushing plate 544; the rotating component 580 includes a second positioning block 586 connected to one side of the support frame 510, one side of the second positioning block 586 is connected to a connecting spring 585, One end of the connecting spring 585 is connected to a first positioning block 584, one side of the first positioning block 584 is connected to a sliding column 582, a rotating pad 583 is horizontally fixedly arranged on the side wall of the sliding column 582, the sliding column 582 is a cylindrical structure, the inner wall of the sliding column 582 is slidably connected to a positioning column 581, the bottom end of the sliding column 582 is connected to a third spring 587, the third spring 587 is connected to the positioning column 581, the bottom end of the positioning column 581 is connected to the operating table 100; the cutting mechanism 600 includes a stamping block 630 connected to the top of the lifting block 250, the inner wall of the stamping block 630 is slidably connected to a support column 610, the There are four groups of support columns 610, the outer wall of the support column 610 located above the stamping block 630 is connected to the stamping part 620, the outer wall of the support column 610 located below the stamping block 630 is connected to the limiting plate 650, the bottom end of the stamping block 630 is connected to the cutting knife 660, the top of the limiting plate 650 is connected to the fourth spring 640, and the fourth spring 640 is provided in two groups, and the fourth spring 640 is connected to the stamping block 630, and the dust removal mechanism 300 includes a slot 310 opened on the positioning plate 260, an electromagnetic box 320 is arranged in the slot of the slot 310, and an iron filings collection box 330 is arranged below the electromagnetic box 320.

[0047] When the steel bar moves forward driven by the feeding mechanism 400, the steel bar moves to fit with the rotating plate 542 and pushes the rotating plate 542 to rotate with the rotating shaft 541 as the axis, thereby driving the moving shaft 543 to rotate with the rotating shaft 541 as the axis, and then driving the pushing plate 544 to move in the direction of the cutting mechanism 600, that is, moving in the direction of the cutting mechanism 600, thereby pushing the rotating pad 583 to move, and then driving the sliding column 582 to rotate with the positioning column 581 as the axis, and driving the first positioning block 584 to rotate, thereby driving the connecting spring 585 to be stretched, and when the rotating pad 583 rotates to fit with the top surface of the punching block 630, the punching head of the stamping part 620, which was originally unable to contact and drive the punching block 630 to move when pressed down, fits with the top surface of the rotating pad 583, and the punching head of the stamping part 620 can drive the rotating pad 583 to move downward when pressed down, thereby driving the punching cutter 660 to move downward and punch, so as to cut the steel bar below. When the cutting blade 660 is driven by the punch 620 to move upward after cutting, the third spring 587 is reset to drive the sliding column 582 to reset. At the same time, when the punch 620 drives the punch block 630 to press down, the fourth spring 640 is also compressed to a compressed state. When the punch 620 drives the punch block 630 to move upward, the downward pressure disappears, and the fourth spring 640 is reset to a compressed state, so that the height of the top cutting blade 660 is reset. When the first positioning block 584 rotates, the connecting spring 585 is in a stretched state. After the steel bar is cut, the force pushing the rotating pad 583 disappears. At this time, the connecting spring 585 is reset, thereby driving the rotating pad 583 that originally rotated with the positioning column 581 as the axis to reset.

[0048] When adjusting the length of the steel bar cutting, the threaded rod 550 is rotated to drive the slider 530 to move. Since the slider 530 connected to the threaded rod 550 is provided with a thread matching the thread of the outer wall of the threaded rod 550, and the limiting groove 520 limits the slider 530, the limiting groove 520 can only slide along the slider 530, so that the threaded rod 550 is rotated to drive the slider 530 to slide in the limiting groove 520, and then drive the indicator needle 560 to move. The length of the cut steel bar can be adjusted, wherein when the indicator needle 560 points to the scale closer to the direction of the cutting mechanism 600, the pushing plate 544 is closer to the rotating pad 583 in the initial state, so that the rotating pad 583 rotates to between the stamping part 620 and the stamping block 630 faster under the drive of the pushing plate 544, and the rotating plate 542 is closer to the steel bar, the length of the steel bar between the rotating plate 542 and the cutting knife 660 is shorter, and the cut steel bar is shorter, and vice versa.

[0049] Optionally, when the punching block 630 is reset upward, the control switch electrically connected to the electromagnetic box 320 is started, thereby driving the electromagnetic box 320 to be energized. At this time, the electromagnetic box 320 drives the magnetism, and the magnetic force of the electromagnetic box 320 is relatively small. The iron filings generated during cutting below the cutting knife 660 are adsorbed, and only small iron filings generated during cutting are adsorbed, which will not affect the movement of the steel bars. When the punching block 630 stops moving and drives the switch of the electromagnetic box 320 to be closed, the magnetism of the electromagnetic box 320 disappears, and the iron filings originally adsorbed on the electromagnetic box 320 fall into the iron filing collection box 330 for centralized collection. The parts not involved in the device are the same as the prior art or can be implemented using the prior art.
