Description

Technical Field

[0001] The present invention relates to the technical field of steel bar cutting, and particularly to an automatic equal-division cutting device for steel bars used in construction projects. Background Art

[0002] A steel bar cutting machine is a tool used for shearing steel bars, which can be divided into a fully automatic steel bar cutting machine and a semi-automatic steel bar cutting machine. It is mainly used for the fixed-length cutting of steel bars in civil engineering and is an essential device in the steel bar processing link. Compared with other cutting devices, it has the advantages of light weight, low energy consumption, reliable operation, and high efficiency. Therefore, it has been widely adopted in the field of mechanical processing and has played an important role in the process of national economic construction.

[0003] During the process of traditional steel bar cutting, the cut debris will fly everywhere, affecting the work of the surrounding operators. The traditional steel bar cutting equipment cannot autonomously adjust the cutting equipment according to the hardness of the steel bars. Secondly, some steel bars with high hardness will cause harm to the operators during cutting, affecting personal safety and work efficiency. Therefore, it is very necessary to design an automatic equal-division cutting device for steel bars used in construction projects with strong practicability, which can avoid the flying of debris during steel bar cutting, can autonomously adjust the cutting strength, and can avoid causing injuries to personnel during cutting. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic equal-division cutting device for steel bars used in construction projects to solve the problems raised in the above background art.

[0005] To solve the above technical problems, the present invention provides the following technical solution: An automatic equal-division cutting device for steel bars used in construction projects, including a load-bearing seat, the upper surface of the load-bearing seat is fixedly connected with a frame, one end of the load-bearing seat far from the frame is fixedly connected with a frame plate, the inner surface of the frame is fixedly connected with a cutting operation box, both inner surfaces of the two sides of the cutting operation box are provided with rotating collection grooves, a cutting device is rotatably connected inside the rotating collection grooves, a pushing mechanism is slidably connected to the surface of the cutting operation box far from the frame plate, a partition board is slidably connected to the end of the cutting operation box close to the frame plate, a lifting arc block is fixedly connected to the outer surface of the partition board, a sliding groove frame is interactively connected to the surface of the lifting arc block, and the bottom of the sliding groove frame is fixedly connected to the surface of the frame plate;

[0006] The pushing mechanism includes a guide seat plate, an input port is provided on the surface of the guide seat plate, two sides of the outer surface of the guide seat plate are fixedly connected with limit balls, a support plate is fixedly connected to the surface of the limit balls, the support plate is fixedly connected to the surface of the frame plate, and a pushing opening is fixedly connected to the upper surface of the support plate.

[0007] According to the above technical solution, a support ring is sleeved on the outer surface of the side of the pushing opening away from the guide seat plate. A guide rod is fixedly connected to the outer surface of the support ring. A spring is sleeved on the outer surface of the guide rod. A connecting seat is fixedly connected to the outer surface of the guide rod. The connecting seat is arranged inside the input port. Clamping elastic pieces are arranged on the outer surface of the connecting seat.

[0008] According to the above technical solution, the pushing opening includes a guide plate. A guide frame is fixedly connected to the surface of the guide plate. A push plate is slidably connected to the surface of the guide frame. A placement groove is formed on the surface of the push plate. A pushing trigger plate is slidably connected inside the placement groove. When an operator places a steel bar into the input port on the surface of the guide seat plate and pushes the steel bar, the guide plate inside the pushing opening is stressed and slides, causing the push plate inside the guide frame to be squeezed. When the push plate moves to the front of the support ring, at this time the pushing trigger plate is outside the push plate. The steel bar pushes to drive the opening and closing plate to slide through the trigger rod, so that the opening and closing plate is in an open state, allowing the steel bar to be conveyed forward through the opening and closing plate to the connecting seat. The clamping elastic pieces will clamp the steel bar, slowing down the pushing speed of the steel bar, thereby transmitting to the operator the position of the steel bar inside the cutting box. The clamped steel bar is more stable during cutting, will not shift, reducing the loss of the steel bar and preventing the steel bar from shifting and damaging the cutting device.

[0009] According to the above technical solution, the pushing trigger plate includes an opening and closing plate. There are two opening and closing plates. Trigger rods are fixedly connected to the surfaces of the two opening and closing plates. A connecting ring is rotatably connected to the top end of the trigger rod. The trigger rod is in extrusion fit with the guide plate.

[0010] According to the above technical solution, the connecting ring is slidably connected to the surface of the push plate. Reset plates are slidably connected to both sides inside the push plate. The trigger rod is fixedly connected to the surface of the reset plate. A reset spring is fixedly connected to the surface of the reset plate. During the cutting of the steel bar, vibrations are generated on the surface of the steel bar, which are transmitted to the surface of the trigger rod through the clamping elastic pieces, causing the trigger rod to slide on the surface of the connecting ring. When encountering a steel bar with a greater hardness and the second blade slides down, the cutting force increases. The vibration frequency of the trigger rod increases. If the operator behind continues to push the steel bar at this time, it may cause casualties. Therefore, by increasing the sliding frequency of the trigger rod, the opening and closing plate collides with the reset plate, and the reset spring on the surface of the reset plate pushes the opening and closing plate backward, causing the push plate to stop and unable to push forward. The higher the vibration frequency, the stronger the pushing force, thus reminding the operator to avoid accidents.

[0011] According to the above technical solution, the cutting device includes a limit cover plate. A central shaft is rotatably connected to the outer surface of the limit cover plate. A motor is fixedly connected to the axis of the central shaft. An activity cavity is fixedly connected to the outer surface of the central shaft.

[0012] According to the above technical solution, a sector-shaped connecting block is fixedly connected to the outer surface of the movable cavity. A second blade is fixedly connected to the outer surface of the sector-shaped connecting block. A built-in groove is formed in the outer surface of the second blade. A sliding groove is formed in the inner wall of the built-in groove. A movable rod is slidably connected to the inside of the sliding groove. First blades are fixedly connected to the outer surface of the movable rod. When the motor rotates to drive the central shaft to rotate, the bent part on the side of the first blade can take away some debris during rotation. When the steel bar is relatively hard, the movable rod slides downward under force, causing the second blade to cut, enabling the device to cut steel bars of different hardnesses.

[0013] According to the above technical solution, the limit cover plate includes a bent cover plate. A sleeve groove is formed in the outer surface of the bent cover plate. A swing rod is rotatably connected to the inside of the sleeve groove. A rubber ball is fixedly connected to the top end of the swing rod. After entering the cutting box, the limit cover plate will rotate downward to block the steel bar to be cut. Then the motor will drive the cutting device to rotate. Since debris will be continuously generated during the cutting of the steel bar, the debris hits the surface of the bent cover plate and then falls, preventing the debris from splashing everywhere. At the same time, the debris hits the swing rod, causing the swing rod to rotate, so that the rubber ball repeatedly hits the bent cover plate, making the bent cover plate vibrate continuously, and preventing the debris and dust from adhering to the bent cover plate.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0015] For the automatic equal-division cutting device for steel bars in construction engineering, the operator puts the steel bar into the input port on the surface of the guide seat plate. When pushing the steel bar, the guide plate in the pushing opening is forced to slide, so that the push plate in the guide frame is squeezed. When the push plate moves to the front of the support ring, at this time, the push trigger plate is on the outside of the push plate. The steel bar pushes the trigger rod to drive the opening and closing plate to slide, so that the opening and closing plate is in an open state, allowing the steel bar to be conveyed forward through the opening and closing plate and transported to the connecting seat. The clamping elastic piece will clamp the steel bar, slowing down the pushing speed of the steel bar, thereby transmitting the position of the steel bar in the cutting box to the operator. The clamped steel bar is more stable during cutting, will not shift, reducing the loss of the steel bar and preventing the steel bar from shifting and damaging the cutting device.

[0016] For the automatic equal-division cutting device for steel bars in construction engineering, after entering the cutting box, the limit cover plate will rotate downward to block the steel bar to be cut. Then the motor will drive the cutting device to rotate. Since debris will be continuously generated during the cutting of the steel bar, the debris hits the surface of the bent cover plate and then falls, preventing the debris from splashing everywhere. At the same time, the debris hits the swing rod, causing the swing rod to rotate, so that the rubber ball repeatedly hits the bent cover plate, making the bent cover plate vibrate continuously, and preventing the debris and dust from adhering to the bent cover plate.

[0017] The automatic equal - division cutting device for steel bars in construction projects drives the central shaft to rotate through the rotation of the motor. When the side - bent part of the first blade rotates, it can take away some debris. When the steel bar is relatively hard, the movable rod is forced to slide downward, enabling the second blade to cut, so that the device can cut steel bars of different hardnesses.

[0018] When the automatic equal - division cutting device for steel bars in construction projects cuts the steel bars, vibrations are generated on the surface of the steel bars. These vibrations are transmitted to the surface of the trigger rod through the clamping elastic pieces, causing the trigger rod to slide on the surface of the connecting ring. When encountering a relatively hard steel bar, after the second blade slides down, the cutting force changes. The vibration frequency of the trigger rod increases. If the operator behind continues to push the steel bar at this time, it may cause casualties. Therefore, by increasing the sliding frequency of the trigger rod, the opening - closing plate collides with the reset plate. The reset spring on the surface of the reset plate pushes the opening - closing plate backward, stopping the push plate from pushing forward. The higher the vibration frequency, the stronger the pushing force, thus reminding the operator to avoid accidents. Brief Description of the Drawings

Embodiment

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1 - 8 , the present invention provides a technical solution: a steel bar automatic equal division cutting device for construction engineering, including a load-bearing seat 6, the upper surface of the load-bearing seat 6 is fixedly connected with a frame 5, one end of the load-bearing seat 6 far from the frame 5 is fixedly connected with a shelf board 1, the inner surface of the frame 5 is fixedly connected with a cutting operation box 3, rotating collection grooves 2 are opened on both inner surfaces of the cutting operation box 3, a cutting device 7 is rotatably connected inside the rotating collection groove 2, a pushing mechanism 4 is slidably connected to the surface of one end of the cutting operation box 3 far from the shelf board 1, a partition board 8 is slidably connected to one end of the cutting operation box 3 close to the shelf board 1, the outer surface of the partition board 8 is fixedly connected with a lifting arc-shaped block 9, the surface of the lifting arc-shaped block 9 is interactively connected with a chute frame 10, and the bottom of the chute frame 10 is fixedly connected to the surface of the shelf board 1;

[0031] The pushing mechanism 4 includes a guide seat plate 44, an input port is opened on the surface of the guide seat plate 44, limiting balls 45 are fixedly connected to both sides of the outer surface of the guide seat plate 44, a support plate 46 is fixedly connected to the surface of the limiting ball 45, the support plate 46 is fixedly connected to the surface of the shelf board 1, and a pushing opening 47 is fixedly connected to the upper surface of the support plate 46.

[0032] A support ring 48 is sleeved on the outer surface of the pushing opening 47 away from one side of the guide seat plate 44. A guide rod 49 is fixedly connected to the outer surface of the support ring 48. A spring 43 is sleeved on the outer surface of the guide rod 49. A connecting seat 42 is fixedly connected to the outer surface of the guide rod 49. The connecting seat 42 is arranged inside the feeding port. Clamping elastic pieces 41 are arranged on the outer surface of the connecting seat 42.

[0033] The pushing opening 47 includes a guide plate 474. A guide frame 471 is fixedly connected to the surface of the guide plate 474. A push plate 472 is slidably connected to the surface of the guide frame 471. A placement groove 475 is formed in the surface of the push plate 472. A pushing trigger plate 473 is slidably connected inside the placement groove 475. When an operator places a steel bar into the feeding port on the surface of the guide seat plate 44 and pushes the steel bar, the guide plate 474 inside the pushing opening 47 is stressed and slides, so that the push plate 472 inside the guide frame 471 is extruded. When the push plate 472 moves to the front of the support ring 48, at this time, the pushing trigger plate 473 is located outside the push plate 472. The steel bar pushes to drive the trigger rod 4734 to drive the opening and closing plate 4731 to slide, so that the opening and closing plate 4731 is in an open state, allowing the steel bar to be conveyed forward through the opening and closing plate 4731 and transported to the connecting seat 42. The clamping elastic pieces 41 will clamp the steel bar, slowing down the pushing speed of the steel bar, thereby transmitting to the operator the position of the steel bar inside the cutting box 3. The clamped steel bar is more stable during cutting, will not shift, reduce the loss of the steel bar, and prevent the steel bar from shifting and damaging the cutting device 7.

[0034] The pushing trigger plate 473 includes an opening and closing plate 4731. There are two opening and closing plates 4731. Trigger rods 4734 are fixedly connected to the surfaces of the two opening and closing plates 4731. The top ends of the trigger rods 4734 are rotatably connected to a connecting ring 4733. The trigger rods 4734 are in extrusion fit with the guide plate 474.

[0035] The connecting ring 4733 is slidably connected to the surface of the push plate 472. On both sides inside the push plate 472, a reset plate 4732 is slidably connected. The trigger rod 4734 is fixedly connected to the surface of the reset plate 4732. A reset spring 4735 is fixedly connected to the surface of the reset plate 4732. When the steel bar is cut, vibrations are generated on the surface of the steel bar and transmitted to the surface of the trigger rod 4734 through the clamping elastic piece 41, causing the trigger rod 4734 to slide on the surface of the connecting ring 4733. When encountering a steel bar with a greater hardness, after the second blade 78 slides down, the cutting force is true or false, and the vibration frequency of the trigger rod 4734 increases. If the operator behind continues to push the steel bar at this time, it may cause casualties. Therefore, by increasing the sliding frequency of the trigger rod 4734, the opening and closing plate 4731 collides with the reset plate 4732, and the reset spring 4735 on the surface of the reset plate 4732 pushes the opening and closing plate 4731 backward, causing the push plate 472 to stop and unable to push forward. The higher the vibration frequency, the stronger the pushing force, thus reminding the operator to avoid accidents.

[0036] The cutting device 7 includes a limit cover plate 71. A central shaft 73 is rotatably connected to the outer surface of the limit cover plate 71. A motor 76 is fixedly connected to the center of the central shaft 73. An activity cavity 74 is fixedly connected to the outer surface of the central shaft 73.

[0037] A sector-shaped connecting block 79 is fixedly connected to the outer surface of the activity cavity 74. A second blade 78 is fixedly connected to the outer surface of the sector-shaped connecting block 79. An internal groove 77 is formed on the outer surface of the second blade 78. A chute is formed on the inner wall of the internal groove 77. A movable rod 72 is slidably connected to the inside of the chute. First blades 75 are fixedly connected to the outer surfaces of the movable rods 72. By driving the rotation of the central shaft 73 by the motor 76, the bent part on the side of the first blade 75 can take away some debris during rotation. When the steel bar has a greater hardness, the movable rod 72 is forced to slide downward, causing the second blade 78 to perform cutting, enabling the device to cut steel bars with different hardnesses.

[0038] The limit cover plate 71 includes a bent cover plate 712. A sleeve groove 714 is formed on the outer surface of the bent cover plate 712. A swing rod 713 is rotatably connected to the inside of the sleeve groove 714. A rubber ball 711 is fixedly connected to the top of the swing rod 713. After entering the cutting box 3, the limit cover plate 71 will rotate downward to block the steel bar to be cut. Then the motor 76 will drive the cutting device 7 to rotate. Since debris will continuously be generated during the cutting of the steel bar, the debris hits the surface of the bent cover plate 712 and falls off, preventing the debris from flying everywhere. At the same time, the debris hits the swing rod 713, causing the swing rod 713 to rotate, so that the rubber ball 711 repeatedly hits the bent cover plate 712, causing the bent cover plate 712 to vibrate continuously, preventing debris and dust from adhering to the bent cover plate 712.

[0039] During use, the operator places the steel bar into the input opening on the surface of the guide seat plate 44. When pushing the steel bar, the guide plate 474 within the opening 47 is forced to slide, causing the push plate 472 within the guide frame 471 to be squeezed. When the push plate 472 moves to the front of the support ring 48, at this time, the push trigger plate 473 is located outside the push plate 472. The steel bar's push causes the trigger rod 4734 to drive the opening and closing plate 4731 to slide, putting the opening and closing plate 4731 in an open state, allowing the steel bar to be conveyed forward through the opening and closing plate 4731 to the connection seat 42. The clamping elastic piece 41 will clamp the steel bar, slowing down the pushing speed of the steel bar, thereby transmitting to the operator the position of the steel bar within the cutting box 3. The clamped steel bar is more stable during cutting, will not shift, reducing the loss of the steel bar and preventing damage to the cutting device 7 caused by the steel bar's deviation; after entering the cutting box 3, the limit cover plate 71 will rotate downward to block the steel bar to be cut. Then, the motor 76 will drive the cutting device 7 to rotate. Since debris is continuously generated during steel bar cutting, the debris strikes the surface of the curved cover plate 712 and falls, preventing the debris from splashing everywhere. At the same time, the debris strikes the swing rod 713, causing the swing rod 713 to rotate, thereby causing the rubber ball 711 to repeatedly strike the curved cover plate 712, continuously vibrating the curved cover plate 712 to prevent debris and dust from adhering to the curved cover plate 712; the rotation of the motor 76 drives the central shaft 73 to rotate. The side bend of the first blade 75 can carry away some debris during rotation. When the steel bar is relatively hard, the movable rod 72 is forced to slide downward, causing the second blade 78 to perform cutting, enabling the device to cut steel bars of different hardnesses; during steel bar cutting, vibrations are generated on the surface of the steel bar and are transmitted to the surface of the trigger rod 4734 through the clamping elastic piece 41, causing the trigger rod 4734 to slide on the surface of the connecting ring 4733. After the second blade 78 slides down when encountering a relatively hard steel bar, the cutting force increases. The vibration frequency of the trigger rod 4734 increases. If the operator behind continues to push the steel bar at this time, it may cause casualties. Therefore, by increasing the sliding frequency of the trigger rod 4734, the opening and closing plate 4731 collides with the reset plate 4732. The reset spring 4735 on the surface of the reset plate 4732 pushes the opening and closing plate 4731 backward, causing the push plate 472 to stop and unable to push forward. The higher the vibration frequency, the stronger the pushing force, thereby reminding the operator to avoid accidents. The operator raises the partition plate 8 to allow the cut steel bar to fall and be collected through the gap between the frame plate 1 and the cutting box 3.
