[0026] Reference Figure 1-5 This utility model provides a cutting machine for H-beams, comprising a base 4, a support frame 1 fixedly connected below the base 4, a second sliding guide plate 18 and a worktable 12 fixedly connected to the support frame 1, a first sliding guide plate 17 and a spark protection box 10 fixedly connected to the worktable 12, guide rails 6 symmetrically fixedly connected to both sides of the base 4, a sliding seat 14 correspondingly provided at the upper end of the guide rails 6, a base plate 22 fixedly connected above the sliding seat 14, a chip removal groove 23 fixedly connected to the base plate 22, and a lead screw shaft 3 provided directly above the base 4, with a nut 16 threadedly connected to the lead screw shaft 3.

[0027] Specifically, the cutting debris enters the chip discharge groove 23 through the bottom of the protective cover 8.

[0028] The right side of the workbench 12 is fixedly connected to a fixing clamp 13.

[0029] Specifically, the fixing clamps 13 on the workbench 12 are used to clamp the H-beams.

[0030] The workbench 12 is fixedly connected to an adjustable clamp 9.

[0031] Specifically, the adjustable clamp 9 on the workbench 12 is used to clamp the H-beam.

[0032] A second support plate 21 is fixedly connected above the base plate 22.

[0033] Specifically, the second support plate 21 is used to fix and connect the base plate 22.

[0034] A stiffening plate 20 is fixedly connected above the second support plate 21, and a first support plate 19 is fixedly connected to the stiffening plate 20. The lower end of the first support plate 19 is fixedly connected to the upper end of the second support plate 21.

[0035] Specifically, the stiffening plate 20 is used to fix the first support plate 19 and the second support plate 21.

[0036] A protective cover 8 is fixedly connected to the first support plate 19. A circular cutting blade 11 is provided inside the protective cover 8. A rotating shaft 24 is fixedly connected to the circular cutting blade 11. A second motor 7 is provided on one side of the rotating shaft 24. The output end of the second motor 7 is fixedly connected to the rotating shaft 24. The outer wall of the second motor 7 is fixedly connected to the first support plate 19.

[0037] Specifically, the second motor 7 drives the rotating shaft 24 to rotate.

[0038] The lead screw shaft 3 is rotatably connected to the first limiting plate 5 and the second limiting plate 15 on both sides. The left end of the lead screw shaft 3 is provided with the first motor 2. The output end of the first motor 2 is fixedly connected to the lead screw shaft 3. The outer wall of the first motor 2 is fixedly connected to the side wall of the base 4.

[0039] Specifically, the first motor 2 drives the lead screw shaft 3 to rotate. When the lead screw shaft 3 rotates, it pushes the nut 16 that it is engaged with to move linearly along the axial direction through thread engagement.

[0040] Nut 16 is fixedly connected to the side wall of base plate 22.

[0041] Specifically, the linear motion of the nut 16 causes the base plate 22 to slide left and right along the guide rail 6. The base plate 22 is further connected to the sliding seat 14, thereby driving the sliding seat 14 to move on the guide rail 6.

[0042] Working principle: The H-beam to be cut is placed on the worktable 12 and initially positioned and fixed by the fixed clamp 13 and adjustable clamp 9 on the right side. The adjustable clamp 9 ensures the stability of the workpiece during the cutting process. The lead screw 3 directly above the base 4 is driven to rotate by the first motor 2, which drives the nut 16 to move axially through the threaded connection. Since the nut 16 is fixed to the side wall of the base plate 22, it pushes the sliding seat 14 to slide left and right along the guide rail 6. The first limiting plate 5 and the second limiting plate 15 on both sides of the lead screw 3 limit the movement range of the sliding seat 14 to prevent overtravel. When the H-beam moves to the cutting station, the second motor 7 drives the rotating shaft 24 to rotate at high speed, which drives the circular cutting blade 11 in the protective cover 8 to cut into the steel. The high-temperature sparks and slag generated by the cutting are blocked by the spark protection box 10 and the protective cover 8. The cutting debris enters the chip discharge groove 23 through the discharge port at the bottom of the protective cover 8. The cut H-beam can slide out through the first sliding guide plate 17 and the second sliding guide plate 18. After completing a single cut, the first motor 2 drives the lead screw shaft 3 in the reverse direction, and the sliding seat 14 returns to the initial position. The above steps are repeated to achieve continuous processing.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
