Technical Field

[0001] This utility model relates to the field of construction equipment technology, specifically a protective rebar cutting machine for construction. Background Technology

[0002] In construction, rebar cutters are indispensable equipment used to cut rebar to the required length. However, existing rebar cutters have many problems.

[0003] On the one hand, during the cutting process, construction workers need to manually move and stabilize the steel bars, which not only makes the steel bars prone to shifting and affects the cutting accuracy, but also exposes the construction workers to the dangers of sparks, waste residue and coolant splashes generated during cutting, posing a significant safety hazard.

[0004] On the other hand, the waste generated during cutting is difficult to clean up, and the coolant is wasted in large quantities, which is not conducive to efficient management and cost control at the construction site. Therefore, we propose a protective steel bar cutting machine for building construction to solve the above problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0028] Reference Figure 1-8This is the first embodiment of the present invention, which provides a construction protection type rebar cutting machine, including a workbench 1 and rebar 3. A receiving mechanism 2 is installed on both sides of the top of the workbench 1, and two clamping mechanisms 4 are arranged between the receiving mechanisms 2. The two clamping mechanisms 4 are fixedly installed on the top surface of the workbench 1. A limiting plate 5 is movably installed on one side of the receiving mechanism 2. One end of the limiting plate 5 is threadedly connected to a threaded rod 6, and the other end of the limiting plate 5 is slidably connected to a sliding rod 10. One end of the threaded rod 6 is rotatably connected to a first limiting block 7, and the other end of the threaded rod 6 rotates through a second limiting block 8 and is then fixedly connected to a knob 9. Both the first limiting block 7 and the second limiting block 8 are fixedly connected to the top surface of the workbench 1. A scale is marked between the first limiting block 7 and the second limiting block 8 on the top surface of the workbench 1. The sliding rod 10 is fixedly connected to both ends of the scale. Support blocks 11 are fixedly connected to the top surface of the workbench 1. Knob 9 drives the threaded rod 6 to rotate. The rotation of the threaded rod 6 further drives the limiting plate 5 to move along the slide rod 10. Two telescopic sealing cylinders are movably sleeved on the outside of the threaded rod 6. One telescopic sealing cylinder is fixedly connected to the first limiting block 7 at one end and to the limiting plate 5 at the other end. The other telescopic sealing cylinder is fixedly connected to the second limiting block 8 at one end and to the limiting plate 5 at the other end. The telescopic sealing cylinders protect the threaded rod and prevent the threaded rod 6 from getting stuck due to waste during cutting, thus ensuring the stability of the device operation. When moving, the limiting plate 5 is precisely moved in conjunction with the scale on the workbench 1. Through the precise positioning of the limiting plate 5, the position of the steel bar 3 is fixed during the cutting process, which significantly improves the cutting accuracy and reduces the generation of steel bar 3 waste.

[0029] An electric actuator 12 is fixedly installed on one side of the clamping mechanism 4. The bottom end of the electric actuator 12 is fixedly connected to one side of the top surface of the workbench 1. The top end of the electric actuator 12 is fixedly connected to one end of the support frame 13. The other end of the support frame 13 is rotatably connected to the blade 14. The blade 14 is fixedly connected to the output shaft of the motor 15. The motor 15 is fixedly connected to one side of the support frame 13. A water pump 16 is provided at the bottom of one side of the support frame 13. The water pump 16 is fixedly installed on the top surface of the workbench 1. The water pump 16 is fixedly connected to the hose 17. One end of the hose 17 slides through the support ring 18 and is fixedly connected to the nozzle 19. The support ring 18 is fixedly connected to one side of the support frame 13. The end of the hose 17 away from the nozzle 19 is fixedly connected to the bottom of the filter box 20. The filter box 20 is fixedly connected to the bottom of the workbench 1. During the cutting process, the water pump 16 draws coolant from the water tank 21. Then, the coolant is transported to the nozzle 19 through the hose 17. The nozzle 19 cools the cutting part during the cutting of the steel bar 3, ensuring the stable operation of the device. Example

[0030] Reference Figure 1-8This is the second embodiment of the present invention, which is based on the previous embodiment. Specifically, multiple drain outlets 29 are provided in the middle of the top of the workbench 1. The drain outlets 29 are connected to the filter box 20. Three layers of filter plates 22 are slidably connected in the filter box 20. A water tank 21 is provided below the filter plates 22. The water tank 21 is slidably connected to the filter box 20. The filter plates 22 and the water tank 21 are connected to the filter box 20 on one side by locking mechanisms 101. The sprayed coolant finally flows into the filter box 20 through the drain outlets 29. After passing through multiple layers of filter plates 22, the coolant is filtered and then flows into the water tank 21. The filtered coolant can be recycled for cutting the steel bar 3. The design of the coolant circulation mechanism realizes the recycling of coolant, reducing coolant consumption and environmental pollution.

[0031] The receiving mechanism 2 includes a support base 201, which is fixedly connected to the top surface of the workbench 1. A roller 202 is rotatably connected to the top of the support base 201. The surface of the roller 202 is provided with an anti-slip rubber layer. The anti-slip rubber layer increases the friction with the steel 3 and prevents the steel bar 3 from slipping during the conveying process.

[0032] The clamping mechanism 4 includes a first mounting base 401, the bottom end of which is fixedly connected to the top surface of the workbench 1, and the top end of which is fixedly connected to a first clamping block 402. A second mounting base 405 is provided on one side of the first mounting base 401, and the second mounting base 405 is fixedly connected to the top surface of the workbench 1. A cylinder 404 is fixedly connected to the top end of the second mounting base 405, and the output shaft of the cylinder 404 is fixedly connected to a second clamping block 403. The first clamping block 402 and the second clamping block 403 are arranged opposite to each other. The cylinder 404 drives the second clamping block 403 to move. The second clamping block 403 cooperates with the first clamping block 402 to fix and clamp the steel bar 3, ensuring the stability of the steel bar 3 during the cutting process.

[0033] The locking mechanism 101 includes a mounting shell 23, which is fixedly installed on one side of the filter box 20. One end of a spring 24 is fixedly connected to one end of the inner wall of the mounting shell 23, and the other end of the spring 24 is fixedly connected to a locking block 25. The locking block 25 slides and engages with a limiting sleeve 26, which is fixedly installed on the water tank 21 and the filter plate 22 respectively. A handle 27 is fixedly connected to the locking block 25, and the handle 27 is movably disposed in a sliding groove 28, which is formed on the mounting shell 23. In use, by moving the handle 27, the handle 27 drives the locking block 25 to move along the sliding groove 28. The locking block 25 moves and releases the locking sleeve 26, after which the filter plate 22 and the water tank 21 can be replaced and cleaned, improving the convenience of operation and ensuring the stable operation of the device.

[0034] A protective shell 30 is fixedly connected to the top surface of the workbench 1. A transparent viewing window 31 is provided on the protective shell 30. The safety design of the protective shell 30 effectively avoids direct contact between the operator and the cutting parts, reduces the injury to the operator caused by sparks, waste residue and coolant splashes, and greatly improves the safety of operation.

[0035] The nozzle 19 is positioned directly opposite the bottom of the blade 14. During the cutting process of the steel bar 3, the nozzle 19 cools the cutting part to ensure the stable operation of the device.

[0036] In use, firstly, adjust the position of the limiting plate 5 according to the required length of the steel bar 3 to be cut. By rotating the knob 9, the knob 9 drives the threaded rod 6 to rotate. The threaded rod 6 further drives the limiting plate 5 to move along the slide rod 10. During the movement, the limiting plate 5 is precisely moved in accordance with the scale on the worktable 1. Then, the steel bars 3 are placed on the rollers 202. After the steel bars 3 pass through the rollers 202, they abut against the limiting plate 5. Then, the second clamping block 403 is moved by the cylinder 404. The second clamping block 403 cooperates with the first clamping block 402 to fix and clamp the steel bars 3. Then, the support frame 13 is moved by the electric push rod 12. The support frame 13 drives the blade 14 to move synchronously to cut the steel bars 3. The stable conveying of the receiving mechanism 2, the precise positioning of the limiting plate 5, and the lifting control of the cutting mechanism ensure that the position of the steel bars 3 is fixed during the cutting process, which significantly improves the cutting accuracy and reduces the generation of steel bar waste.

[0037] During the cutting process, the water pump 16 draws coolant from the water tank 21, and then the coolant is delivered to the nozzle 19 through the hose 17. The nozzle 19 cools the cut part during the cutting of the steel bar 3. The sprayed coolant finally flows into the filter box 20 through the drain port 29, and then passes through the multi-layer filter plate 22 to filter the coolant. After filtration, the coolant flows into the water tank 21. The filtered coolant can be recycled for cutting the steel bar 3. The design of the coolant circulation mechanism realizes the recycling of coolant, reducing coolant consumption and environmental pollution.
