Technical Field

[0001] This utility model relates to the technical field of rebar cutting equipment, and in particular to a rebar cutting machine that prevents splashing. Background Technology

[0002] In the process of water conservancy and hydropower construction, steel bars are used to enhance the structural strength. Before use, the steel bars need to be cut according to the actual needs. Due to the high strength of the steel bars, a large number of sparks and debris are generated when the high-speed rotating cutting blade comes into contact with them and performs the cutting operation.

[0003] Existing rebar cutting machines tend to generate sparks and debris when cutting rebar, which are not very protective and can easily cause injury to operators. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a splash-proof rebar cutter that can effectively prevent the splashing of sparks and debris, avoid injury to operators, and improve the protective effect.

A cutting motor 6 is fixedly installed on the lower side of the front end of the L-shaped support plate 5. A cutting blade 7 is fixedly installed on the output shaft of the cutting motor 6. A processing table 8 is fixedly provided at the center of the top of the base 1. A U-shaped opening is provided in the middle of the top of the processing table 8. The positioning groove 10 and the cutting groove 9 extending downward from the top of the processing table 8 are provided. The cutting groove 9 divides the U-shaped positioning groove 10 into front and rear sections. Two sets of connecting strips 12 are fixedly connected to the front and rear ends of the two sets of protective covers 11. Two sets of connecting shafts 13 are symmetrically fixed on both sides of the fixing frame 2. The two sets of protective covers 11 are symmetrically rotated and installed inside the fixing frame 2 through the cooperation of the connecting strips 12 and the connecting shafts 13. Lower hinge seats 14 are fixedly provided at the inner position of the top of the two sets of protective covers 11. Transmission rods 15 are rotatably connected to the two sets of lower hinge seats 14. Both sides of the bottom end of the connecting plate 4 are fixedly provided with upper hinge seats 16. The top ends of the two sets of transmission rods 15 are respectively rotatably connected to the two sets of upper hinge seats 16. Trapezoidal protective shells 17 are fixedly connected to both sides of the cutting groove 9. The outer sides of the two sets of trapezoidal protective shells 17 are respectively fixedly connected to the inner walls of the left and right sides of the fixed frame 2. In use, the U-shaped positioning groove 10 can make the steel bar and the cutting blade 7 vertically placed on the processing table 8. When cutting, hold the steel bar by hand, start the hydraulic cylinder 3 to push the connecting plate 4 downward to feed the cutting blade 7 downward. Start the cutting motor 6. The cutting motor 6 drives the cutting blade 7 to rotate, cutting the steel bars. During the cutting process, the connecting plate 4 blocks the cutting blade 7 from above. As the connecting plate 4 moves down, the two sets of protective covers 11 rotate inward, blocking the cutting blade 7 from the upper left and upper right respectively. The cutting groove 9 can accommodate the cutting motion of the cutting blade 7, while the trapezoidal protective shells 17 on both sides of the cutting groove 9 block the cutting blade 7 from the lower left and lower right respectively, thus effectively preventing the splashing of sparks and debris, avoiding injury to the operator, and improving the protection effect.

[0019] A baffle 19 is fixedly connected to the inner rear end of the processing table 8. A collection box 18 is inserted inside the processing table 8. The bottom end of the collection box 18 contacts the top end of the base 1, the front end of the collection box 18 is aligned with the front end of the processing table 8, and the rear end of the collection box 18 abuts against the front end of the baffle 19. During the cutting process, the generated debris will slide down the trapezoidal protective shell 17. The collection box 18 can collect the sliding debris, which brings convenience to the debris cleaning.

[0020] The front end of the collection box 18 is fixedly provided with a handle 20; by providing the handle 20, the collection box 18 can be picked up and put down by holding the handle 20, which makes it more convenient to pick up and put down.

[0021] The left and right ends of the fixed frame 2 are fixedly connected to the top of the base 1 with reinforcing plates 21; by setting the reinforcing plates 21, the connection between the fixed frame 2 and the base 1 can be made more firm and stable.

[0022] This utility model discloses a rebar cutting machine with anti-sparking mechanism. In operation, the U-shaped positioning groove 10 allows the rebar and cutting blade 7 to be placed vertically on the processing table 8. During cutting, the rebar is held firmly by hand, and the hydraulic cylinder 3 is activated to push the connecting plate 4 downwards, feeding the cutting blade 7 downwards. The cutting motor 6 is activated, causing the cutting blade 7 to rotate and cut the rebar. During the cutting process, the connecting plate 4 blocks the cutting blade 7 from above. As the connecting plate 4 moves downwards, the transmission rod 15 drives the protective cover 11 to rotate inwards, allowing two sets of protective covers 11 to block the upper left and upper right positions of the cutting blade 7, respectively. The cutting groove 9 accommodates the cutting motion of the cutting blade 7, while the trapezoidal protective shells 17 on both sides of the cutting groove 9 block the lower left and lower right positions of the cutting blade 7, preventing sparks and debris from flying. The generated debris is guided by the bottom of the trapezoidal protective shell 17 and falls into the collection box 18 for collection.
