Description

Technical Field

[0001] This utility model relates to the field of building engineering equipment technology, and in particular to a building engineering steel bar cutting device with a protective structure. Background Technology

[0002] In construction engineering, steel reinforcement is one of the main structural materials, and its processing is a crucial step in the construction process. Steel reinforcement cutting is a fundamental procedure in steel reinforcement processing, used to cut steel reinforcement of different specifications into specific lengths according to the construction drawings to meet the needs of subsequent construction such as component fabrication and binding. As the core tool for completing this process, steel reinforcement cutting equipment is closely related to the progress of the construction industry.

[0003] Traditional cutting equipment in the current technology exposes the cutting blade, posing a high risk of flying steel bar fragments; manual equipment requires close-range operation, which can easily lead to hand injuries due to steel bar slippage; some mechanical devices lack protective structures, posing risks of pinching and collision injuries. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a steel bar cutting device for building engineering with a protective structure.

[0005] This utility model is achieved by the following technical solution: a steel bar cutting device for building engineering with a protective structure, including a cutting shell, a protective component inside the cutting shell, and an auxiliary component inside the protective component.

[0006] The protective assembly includes a hydraulic drive device, which is fixedly connected to the top of the cutting shell. A drive rod is slidably connected to the output end of the hydraulic drive device. A cutting tool is fixedly connected to the outer wall of the drive rod. A feeding top mold is fixedly connected to the outer wall of the cutting shell. A dragging bottom mold is provided on the right side of the feeding top mold. The dragging bottom mold is fixedly connected to the outer wall of the cutting shell. A T-shaped groove is formed on the surface of the cutting shell. A T-shaped slider is slidably connected to the inner wall of the T-shaped groove. A protective top plate is fixedly connected to the surface of the T-shaped slider. The protective top plate is fixedly connected to the outer wall of the drive rod.

[0007] As a further improvement to the above solution, several cutting tools are provided, and several T-shaped grooves are provided, with the several T-shaped grooves arranged symmetrically around the protective top plate.

[0008] As a further improvement to the above solution, several T-shaped sliders are provided, and the several T-shaped sliders are symmetrically arranged with the protective top plate as the center.

[0009] Through the above technical solution, the hydraulic drive equipment operates, and the output end of the hydraulic drive equipment generates thrust to push the drive rod. The drive rod transmits the thrust to the cutting tool, causing the cutting tool to move towards the steel bar on the surface of the feeding top mold and complete the cutting action. During this process, the drive rod synchronously drives the protective top plate to move, and the protective top plate drives the T-shaped slider to slide along the T-shaped groove towards the dragging bottom mold.

[0010] As a further improvement to the above solution, the auxiliary component includes a fixing plate, which is fixedly connected to the top of the cutting shell. A limit rod is fixedly connected to the front of the fixing plate, and a feeding limit plate is slidably connected to the outer wall of the limit rod. The end of the limit rod away from the hydraulic drive device is fixedly connected to the inner wall of the cutting shell.

[0011] As a further improvement to the above solution, a motor fixing block is fixedly connected to the front of the cutting shell, a drive motor is fixedly connected to the inner wall of the motor fixing block, a drive threaded rod is fixedly connected to the output end of the drive motor, the outer wall of the drive threaded rod is threadedly connected to the inner wall of the feeding limit plate, and the end of the drive threaded rod away from the drive motor is rotatably connected to the inner wall of the fixing plate.

[0012] As a further improvement to the above solution, a limiting groove is provided on the inner wall of the feeding top mold, and a driving cylinder is fixedly connected to the inner wall of the limiting groove. A piston rod is slidably connected to the output end of the driving cylinder, and a limiting push plate is fixedly connected to the end of the piston rod away from the driving cylinder.

[0013] As a further improvement to the above solution, an auxiliary push rod is fixedly connected to the end of the limiting push plate away from the piston rod, and a discharge push plate is fixedly connected to the end of the auxiliary push rod away from the limiting push plate. The outer wall of the discharge push plate is slidably connected to the inner wall of the feeding top mold.

[0014] Through the above technical solution, during the process of the cutting tool cutting the steel bar, the other end of the cutting tool is limited by the feeding limit plate, so as to prevent the steel bar from lifting due to uneven force, avoid problems such as skewed cut and steel bar deformation, and ensure that the cut is flat and the dimensions are accurate. Then, the drive motor is run, the output end of the drive motor rotates and drives the threaded rod, so that the feeding limit plate slides along the outer wall of the drive threaded rod and the limit rod.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention utilizes a hydraulic drive system. The output of the hydraulic drive system generates thrust to push a drive rod, which transmits the thrust to the cutting blade. This causes the cutting blade to move towards the steel bar on the surface of the feeding mold and complete the cutting action. During this process, the drive rod simultaneously moves the protective top plate. The protective top plate drives the T-shaped slider to slide along the T-shaped groove towards the dragging bottom mold. Due to the height difference between the feeding mold and the dragging bottom mold, the cut steel bar slides from the feeding mold to the lower dragging bottom mold under gravity. At this point, the protective top plate, which has slid to the corresponding position, limits the steel bar on the dragging bottom mold, preventing it from shifting before subsequent processes. The automated operation driven by hydraulics reduces manual intervention, allowing operators to stay away from the core cutting area and only need to monitor the equipment operation, thus reducing the accident rate.

[0017] This invention utilizes a cutting tool that, during the cutting process, has a feeding limiting plate at one end of the cutting tool to prevent the rebar from warping due to uneven force, thus avoiding problems such as skewed cuts and rebar deformation. This ensures a smooth cut and precise dimensions. Then, a drive motor is activated, its output rotating and driving a threaded rod. This causes the feeding limiting plate to slide along the outer walls of the threaded rod and the limiting rod, pushing the rebar towards the cutting tool. Simultaneously, the feeding limiting plate is limited by symmetrically arranged limiting rods, completing the automated feeding process. This avoids the interruptions of manual feeding, significantly shortens the processing cycle of a single rebar, and improves batch production efficiency. After the cutting tool completes the cutting operation and resets, a drive cylinder is activated, its output pushing a piston rod. The piston rod pushes a limiting push plate, which in turn pushes an auxiliary push rod. The auxiliary push rod pushes a discharge push plate, causing the discharge push plate to push the rebar cut from the bottom mold outwards. This eliminates the need for manual material handling, avoids process interruptions, and allows for direct connection to subsequent conveying and stacking processes, improving the overall continuity of the production line.

The protective top plate 208 is fixedly connected to the outer wall of the drive rod 202.

[0032] Several T-shaped sliders 207 are provided, and the T-shaped sliders 207 are symmetrically arranged with the protective top plate 208 as the center.

[0033] The auxiliary component 3 includes a fixing plate 301, which is fixedly connected to the top of the cutting shell 1. A limit rod 302 is fixedly connected to the front of the fixing plate 301. A feeding limit plate 303 is slidably connected to the outer wall of the limit rod 302. One end of the limit rod 302 away from the hydraulic drive device 201 is fixedly connected to the inner wall of the cutting shell 1.

[0034] A motor fixing block 304 is fixedly connected to the front of the cutting shell 1. A drive motor 305 is fixedly connected to the inner wall of the motor fixing block 304. A drive threaded rod 306 is fixedly connected to the output end of the drive motor 305. The outer wall of the drive threaded rod 306 is threadedly connected to the inner wall of the feeding limit plate 303. The end of the drive threaded rod 306 away from the drive motor 305 is rotatably connected to the inner wall of the fixing plate 301.

[0035] A limiting groove 307 is provided on the inner wall of the feeding mold 204. A driving cylinder 308 is fixedly connected to the inner wall of the limiting groove 307. A piston rod 309 is slidably connected to the output end of the driving cylinder 308. A limiting push plate 310 is fixedly connected to the end of the piston rod 309 away from the driving cylinder 308.

[0036] An auxiliary push rod 311 is fixedly connected to the end of the limiting push plate 310 away from the piston rod 309.

The outer wall of the output push plate 312 is slidably connected to the inner wall of the feeding top mold 204.

[0037] The implementation principle of a steel bar cutting device with a protective structure in this application embodiment is as follows: The hydraulic drive device 201 generates thrust at its output end, pushing the drive rod 202. The drive rod 202 transmits the thrust to the cutting blade 203, causing the cutting blade 203 to move towards the steel bar on the surface of the feeding top mold 204 and complete the cutting action. During this process, the other end of the cutting blade 203 is limited by the feeding limit plate 303 to prevent the steel bar from warping due to uneven force, ensuring a smooth cut and accurate dimensions. Simultaneously, the drive rod 202 synchronously drives the protective top plate 208 to move, and the protective top plate 208 drives the T-shaped slider 207 to slide along the T-shaped groove 206 towards the dragging bottom mold 205. Because of the height difference between the feeding top mold 204 and the dragging bottom mold 205, the cut steel bars slide from the feeding top mold 204 to the lower dragging bottom mold 205 under the action of gravity. At this time, the protective top plate 208, which has slid to the corresponding position, limits the steel bars on the dragging bottom mold 205 to prevent them from shifting before subsequent processes. After cutting, the hydraulic drive device 201 drives the drive rod 202 to reset, and the cutting tool 203 returns to its initial position with the drive rod 202. The protective top plate 208 drives the T-shaped slider 207 to slide in the opposite direction along the T-shaped groove 206, releasing the limitation on the steel bars. Then, the drive motor 305 is run, and its output end rotates and drives the threaded rod 306, causing the feeding limiting plate 303 to slide along the outer wall of the drive threaded rod 306 and the limiting rod 302, thereby pushing the steel bars to move towards the cutting tool 203. At the same time, the feeding limiting plate 303 is limited by the symmetrically arranged limiting rods 302, completing the automated feeding process of the product. After the cutting tool 203 completes the cutting operation and resets, the drive cylinder 308 is activated. Its output end pushes the piston rod 309, the piston rod 309 pushes the limit push plate 310, the limit push plate 310 pushes the auxiliary push rod 311, and the auxiliary push rod 311 pushes the discharge push plate 312, so that the discharge push plate 312 pushes the steel bar that has been cut on the surface of the dragging bottom mold 205 outwards, so as to carry out the next round of steel bar cutting operation.
