At this time, the rotating roller 3 rotates to transport the steel.

[0051] Specifically, the cutting device includes:

[0052] The second fixing frame 8 is arranged on the upper end surface of the workbench 1;

[0053] The bottom end of the second fixing frame 8 is welded to the upper end surface of the workbench 1 so as to be relatively fixed;

[0054] A sliding block 9 is slidably mounted in the second fixing frame 8;

[0055] The inner wall surface of the second fixed frame 8 is formed with a second slide groove, and the side wall surface of the sliding block 9 is welded with a second sliding block slidably connected to the second slide groove, so that the sliding frame 9 can be more stable when sliding;

[0056] The cutting blade 10 is fixedly mounted on the lower end surface of the sliding block 9;

[0057] A groove 11 is formed on the upper end surface of the workbench 1 and is located below the second fixing frame 8;

[0058] A knife seat 12 is disposed in the groove 11;

[0059] The knife holder 12 is fixedly installed in the groove 11 and can be used in conjunction with the cutting knife 10 to cut steel;

[0060] The second cylinder 23 is arranged on the upper end surface of the second fixing frame 8, and the telescopic end is fixedly connected to the upper end surface of the sliding block 9;

[0061] The extension of the telescopic end of the second cylinder 23 can drive the sliding block 9 to enable the cutting knife 10 to cut the steel;

[0062] The clamping and limiting device is arranged on the workbench 1 and is used for clamping and limiting the steel.

[0063] Specifically, the clamping and limiting device includes:

[0064] The sliding opening 13 is symmetrically formed on the workbench 1;

[0065] A bidirectional threaded rod 14 is rotatably mounted in a pair of sliding openings 13;

[0066] The slider 15 is slidably mounted in the slide opening 13 and is threadedly connected to the bidirectional threaded rod 14;

[0067] The bidirectional threaded rod 14 rotates to drive the pair of sliders 15 to slide in the pair of sliders 13 respectively, so that the pair of sliders 15 move closer to or farther from each other;

[0068] A clamping plate 16 is fixedly mounted on the upper end surface of the slider 15;

[0069] The sliding of a pair of sliders 15 can respectively drive a pair of clamps 16, so that the pair of clamps 16 can limit the two ends of the steel and its position, so that the cutting knife 10 can be more accurate when cutting, preventing the steel from shifting, causing inaccurate cutting position, and causing damage and waste of steel.

[0070] Specifically, a limit plate 17 is slidably mounted on the upper end surface of the workbench 1, and an electric push rod 18 for driving the limit plate 17 is fixedly mounted on the upper end surface of the workbench 1;

[0071] A third slide groove is formed on the upper end surface of the workbench 1, and a third slider slidably connected to the third slide groove is fixedly installed on the lower end surface of the limit plate 17, so that the limit plate 17 can be more stable when sliding. At the same time, the extension of the telescopic end of the electric push rod 18 can drive the limit plate 17 to move, so that it can limit the cutting length of the steel plate;

[0072] A measuring ruler 19 is fixedly mounted on one end surface of the limiting plate 17 close to the first fixing frame 4;

[0073] A pointer 20 is fixedly mounted on the upper end surface of the workbench 1 and located on one side of the second fixing frame 8;

The movement of the limit plate 17 can drive the measuring ruler 19 to move, so that the measuring ruler 19 can measure the length of the steel plate, which is convenient for cutting the steel plate.

[0075] Specifically, the side wall surfaces of the workbench 1 are respectively fixedly mounted with a reducer 21 and a driving member 22, the output end of the driving member 22 is fixedly connected to the input end of the reducer 21, and the output end of the reducer 21 is fixedly connected to one end of the rotating roller 3;

[0076] The driving member 22 is a motor, and the rotation of its output end can drive the input end of the reducer 21 to rotate. The reducer 21 can reduce the rotation speed of the driving member 22 and drive the rotating roller 3 to rotate, so as to transport the steel plate.

[0077] Working principle: First, the staff starts the electric push rod 18. The extension of the telescopic end of the electric push rod 18 can drive the limit plate 17 to move. The movement of the limit plate 17 drives the measuring ruler 19. At this time, under the action of the pointer 20, the length of the steel plate to be cut is measured. At the same time, the limit plate 17 limits the position of the steel plate. At this time, the staff puts one end of the steel plate between a pair of clamps 16. At this time, the staff rotates the bidirectional threaded rod 14. The rotation of the bidirectional threaded rod 14 can drive a pair of sliders 15 to slide in a pair of sliders 13 respectively, so that the pair of sliders 15 are close to each other and limit the two ends of the steel plate, so that their positions are limited to prevent the steel plate from shifting. At this time, the staff starts the driving member 22. The rotation of the output end of the driving member 22 can drive the input end of the reducer 21 to rotate. The reducer 21 The rotation speed of the driving member 22 can be slowed down and the rotating roller 3 can be driven to rotate. At the same time, the staff starts the first cylinder 7. The extension of the telescopic end of the first cylinder 7 can drive the sliding frame 5 to slide, so that the auxiliary roller 6 is close to the rotating roller 3. At this time, the staff inserts one end of the steel plate between the rotating roller 3 and the auxiliary roller 6. At this time, the rotating roller 3 and the auxiliary roller 6 clamp and convey the steel plate. When one end of the steel plate contacts one end surface of the limit plate 17, the staff closes the driving member 22 and starts the second cylinder 23 at the same time. The extension of the telescopic end of the second cylinder 23 drives the sliding block 9, so that the cutting knife 10 and the knife seat 12 cooperate to cut the steel. The cut steel can be collected by the staff, and the driving member 22 can be started again to facilitate the transportation and cutting of the steel plate again, which brings convenience to people.
