Description

Technical Field

[0001] The utility model relates to a steel bar cutting device, in particular to a tied steel bar cutting device, belonging to the technical field of building construction. Background Art

[0002] Steel bars refer to steel used for reinforced concrete and prestressed reinforced concrete. They are indispensable building materials for construction. Their cross-sections are circular, sometimes square with rounded corners. They include plain round steel bars, ribbed steel bars, and twisted steel bars. Since a large number of steel bars of the same specification are often needed in the construction process, the steel bars need to be cut;

[0003] A Chinese patent publication (publication number: CN201921820507.6) discloses a construction steel bar cutting device, which solves the problem that the existing construction steel bar cutting device generates huge noise when slicing and cutting steel bars and cannot be used for steel bars of all diameters. The following scheme is now proposed, which includes a steel plate, a damping layer, a sound-absorbing sponge and a micro-perforated plate. The inner wall of the steel plate is fixedly connected with a damping layer, the outer wall of the damping layer is fixedly connected with a sound-absorbing sponge, and the outer wall of the sound-absorbing sponge is fixedly connected with a micro-perforated plate. The utility model arranges a steel plate, and arranges a damping layer, a sound-absorbing sponge and a micro-perforated plate inside, so that when the device is in use, the noise generated by slicing and cutting steel bars can be absorbed and blocked through the effects of the damping layer, the sound-absorbing sponge and the micro-perforated plate, thereby avoiding long-term use affecting the health of the staff, and when used around a building where people already live, causing trouble to the residents, thereby increasing the practicality of the device and improving the use experience of the staff;

[0004] Although the cutting device reduces the noise generated when cutting the steel bars by setting up a damping layer, sound-absorbing sponge and micro-perforated plate, it requires manual pushing of the steel bars for cutting, and the work efficiency is low. Therefore, a tied steel bar cutting device is proposed. Utility Model Content

[0027] Two groups of feeding components 5 are arranged above the base 1, and the feeding components 5 include a U-shaped frame 501, a first rectangular hole 502, a motor 503, a second rectangular hole 504, a first rotating shaft 505, a feeding roller 506, a pulley 507, a transmission belt 508 and a second rotating shaft 509.

[0028] In one embodiment, a through hole 11 is opened on one side of the fixing plate 6 , and the inner wall of the through hole 11 is in movably contact with the outer side of the movable rod 9 , so that the movable rod 9 is movably installed inside the fixing plate 6 through the through hole 11 .

[0029] In one embodiment, the electrical output end of the touch switch 8 is electrically connected to the electrical input end of the controller 12 through a wire, and the electrical output end of the controller 12 is electrically connected to the electrical input end of the cylinder 3 through a wire. Through the setting of the touch switch 8, when the push plate 7 contacts the touch switch 8, the touch switch 8 transmits a signal to the controller 12, and the controller 12 controls the cylinder 3 to start, driving the cutting knife 4 to move down to cut the steel bars, so that the steel bars can be automatically cut, thereby improving work efficiency.

[0030] In one embodiment, a first rectangular hole 502 is formed on the upper surface of the base 1, a U-shaped frame 501 is fixedly installed on the upper surface of the base 1, a second rectangular hole 504 is formed on the upper surface of the U-shaped frame 501, a first rotating shaft 505 is rotatably installed inside the second rectangular hole 504 through a bearing, a second rotating shaft 509 is rotatably installed inside the first rectangular hole 502 through a bearing, a feeding roller 506 is fixedly sleeved on the outer sides of the second rotating shaft 509 and the first rotating shaft 505, and the outer sides of the first rotating shaft 505 and the second rotating shaft 509 are fixed. A pulley 507 is provided, and a transmission belt 508 is connected between the two pulleys 507. A motor 503 is fixedly installed on one side of the U-shaped frame 501. The rear end of the output shaft of the motor 503 is fixedly connected to the front end of the first rotating shaft 505. The rotating motor 503 drives the first rotating shaft 505 to rotate, and the first rotating shaft 505 drives the second rotating shaft 509 to rotate through the transmission belt 508 and the pulley 507. The rotating first rotating shaft 505 and the second rotating shaft 509 drive the feeding roller 506 to rotate, thereby realizing automatic feeding of steel bars.

[0031] In one embodiment, a rectangular groove cooperating with the cutting knife 4 is provided on the upper surface of the base 1. The rectangular groove effectively prevents the cutting knife 4 from directly contacting the upper surface of the base 1 and causing damage.

[0032] In one embodiment, a fixing hole 13 is opened on one side of the two pulleys 507, and the inner walls of the two fixing holes 13 are fixedly connected to the outer sides of the first rotating shaft 505 and the second rotating shaft 509 respectively, so that the two pulleys 507 are respectively installed on the outer sides of the first rotating shaft 505 and the second rotating shaft 509 through the fixing holes 13.

[0033] The utility model is in operation: when it is necessary to cut the steel bar, the steel bar to be cut is placed between the two feeding rollers 506, and the motor 503 is started, so that the motor 503 drives the first rotating shaft 505 to rotate, and the rotation of the first rotating shaft 505 drives the pulley 507 sleeved on the outside of the first rotating shaft 505 to rotate, and the rotation of the pulley 507 drives the pulley 507 located on the outside of the second rotating shaft 509 to rotate through the transmission belt 508, and the rotation of the pulley 507 located on the outside of the second rotating shaft 509 drives the second rotating shaft 509 to rotate, and the rotation of the second rotating shaft 509 drives the feeding roller 506 located on the outside of the second rotating shaft 509 to rotate, and the two feeding rollers 506 rotate to feed the steel bar, so that the steel bar can be fed by the two rotating feeding rollers 506, and there is no need to push the steel bar manually, thereby reducing the labor intensity;

[0034] The steel bar moves to the left until it contacts the right side of the push plate 7. The steel bar continues to move to the left, pushing the push plate 7 to drive the two movable rods 9 to move to the left. The push plate 7 compresses the spring 10 while moving to the left. When the left side of the push plate 7 contacts the touch switch 8, the touch switch 8 transmits a signal to the controller 12. The controller 12 controls the cylinder 3 to start, so that the cylinder 3 drives the cutting knife 4 to move downward, so that the cutting knife 4 cooperates with the rectangular groove to cut the steel bar. After the cut steel bar is removed from the top of the base 1, the push plate 7 is no longer pushed to the left. The compressed spring 10 is reset. At the same time, the steel bar is still fed by the two rotating feeding rollers 506, so that the steel bar moves to the left. The steel bar again generates a left thrust on the push plate 7, so that the spring 10 is compressed again, and the push plate 7 contacts the touch switch 8 again, so that the cylinder 3 drives the cutting knife 4 to move downward again to cut the steel bar, which is convenient for automatic cutting of the steel bar and improves work efficiency.

[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
