[0053] Please see Figure 1-5 This utility model provides a technical solution: a sawing device for processing square steel, including a working platform 1, and a bottom fixing frame 3 fixedly connected to the lower surface of the working platform 1, the bottom fixing frame 3 being in the shape of a "U".

[0054] Among them, two electric push rods 4 are fixedly connected to the upper surface of the horizontal plate of the bottom fixing frame 3;

[0055] Among them, the upper ends of the two electric actuators 4 are fixedly connected to the fixing blocks 5;

[0056] The work platform 1 is equipped with a sawing mechanism, which includes a connecting groove 2, a support groove 6, a positioning shaft 7, a first motor 8, and a cutting wheel 9.

[0069] Two sliding grooves 10 are formed on the upper surface of the work platform 1, and the sliding grooves 10 extend out of the lower surface of the work platform 1.

[0070] Two bidirectional threaded rods 12 are rotatably connected between the inner walls of the front and rear sides of the two sliding grooves 10, and the front end of the bidirectional threaded rods 12 rotatably passes through the front surface of the working platform 1.

[0071] Furthermore, the collection box 13 is disposed on the lower side of the connecting slot 2;

[0072] Among them, four sliding blocks 11 are slidably connected to two sliding grooves 10, and two corresponding sliding blocks 11 are threadedly sleeved on the outer surface of the corresponding bidirectional threaded rod 12. The two corresponding sliding blocks 11 are located at the two opposite threads of the bidirectional threaded rod 12.

[0073] Two clamping blocks 22 are fixedly connected to the upper surfaces of two sliding blocks 11, and the lower surface of the clamping blocks 22 is slidably connected to the upper surface of the work platform 1.

[0074] Two mounting slots 15 are formed on the outer surfaces of the left and right sides of the protective cover 14. The mounting slots 15 extend into the protective cover 14 and extend downward out of the lower surface of the protective cover 14.

[0075] Furthermore, two limiting grooves 20 are formed on the top wall of the two mounting grooves 15;

[0076] Among them, the two baffles 16 are slidably connected to the two limiting slide grooves 20, and the two baffles 16 are slidably connected to the two mounting grooves 15;

[0077] Among them, two positioning grooves 19 are formed on the outer surfaces of the left and right sides of the protective cover 14, and the lower surface of the baffle 16 extends downward into the mounting groove 15.

[0078] Among them, the two positioning slides 19 are connected to the two limiting slides 20.

[0079] Furthermore, the two push blocks 18 are fixedly connected to the outer surfaces of the two baffles 16 on opposite sides;

[0080] Among them, the two push blocks 18 are slidably connected to the two positioning grooves 19;

[0081] Two positioning bolts 17 are threaded onto the outer surfaces of the left and right sides of the protective cover 14.

[0082] Among them, two positioning bolts 17 are threaded into two limiting slide grooves 20, and one end of the positioning bolt 17 that penetrates into the limiting slide groove 20 contacts the outer surface of the baffle 16.

[0083] The protective cover 14 is slidably connected between the clamping blocks 22 on the left and right sides;

[0084] Among them, the outer surfaces of the two adjacent sides of the clamping blocks 22 on the front and rear sides are connected.

[0085] In use, place the square steel between the clamping blocks 22 on the front and rear sides, and then rotate the bidirectional threaded rod 12. The rotation of the bidirectional threaded rod 12 synchronously drives the clamping blocks 22 on the front and rear sides to move in opposite or opposite directions. During the relative movement of the two corresponding sliding blocks 11, the two corresponding clamping blocks 22 also clamp and fix the square steel, preventing the square steel from shifting during sawing, thereby ensuring the stability of square steel sawing and ensuring the quality of square steel sawing.

[0086] After the square steel is clamped and fixed by the clamping block 22, the protective cover 14 is rotated to close it. Then, the pushing block 18 is pushed down, causing the pushing block 18 to move the baffle 16 downward. When the lower surface of the baffle 16 contacts the upper surface of the square steel, the positioning bolt 17 is rotated to press the positioning bolt 17 tightly against the outer surface of the baffle 16 near the first motor 8, thereby fixing the baffle 16. At this time, the baffle 16 has a certain restriction effect on the square steel, preventing it from moving upward. At this time, the baffle 16 and the sliding block 11 cooperate to shield the mounting groove 15, preventing debris from splashing out of the mounting groove 15 during the sawing of the square steel. This greatly improves the safety of the working environment, ensures the safety of sawing the square steel, provides safety protection for the workers, and increases the safety of the sawing device.

[0087] In this solution, when the electric actuator 4 and the first motor 8 are started, the first motor 8 drives the positioning shaft 7 to rotate, which in turn drives the cutting wheel 9 to rotate. The rotating cutting wheel 9 can saw the square steel. The electric actuator 4 drives the fixing block 5 to move up and down, which in turn drives the cutting wheel 9 to move upward, thus sawing the square steel. During the upward sawing process, the cutting wheel 9 saws the square steel from bottom to top, thereby reducing the splashing of debris and reducing pollution to the surrounding environment. The splashed debris will fall into the collection frame 13 through the connecting groove 2, which largely realizes the collection of debris, keeps the working area clean, and facilitates subsequent cleaning work, thereby increasing the practicality and safety of the sawing device.
