[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1-4 A pre-cutting device for bearing steel pipes includes a base 1, on which a column 8 is mounted. The column 8 supports the installation of a support platform 7. The support platform 7 is fixedly mounted on the top of the column 8 and supports the installation of a cutting mechanism. A protective mechanism is fixedly mounted on the bottom of the support platform 7. The protective mechanism serves to protect the bearing steel pipe during cutting, preventing debris from splashing. The cutting mechanism is mounted on the support platform 7, which facilitates the adjustment of the cutting machine position and allows for cutting at different positions on the bearing steel pipe. The protective mechanism includes a first motor 24, which has a positive... The reverse function is achieved by setting up the first motor 24 to drive the first lead screw 22 to rotate. The first motor 24 is fixedly installed at the bottom end of the support platform 7. The first lead screw 22 is fixedly installed at the shaft end of the first motor 24. The first lead screw 22 is used to drive the protective frame 21 to move vertically along the surface of the limiting rod 23. The protective frame 21 is threadedly connected to the first lead screw 22. The protective frame 21 is set up to prevent the occurrence of debris splashing during the cutting process. The limiting rod 23 is fixedly installed at the bottom end of the support platform 7. The protective frame 21 slides on the limiting rod 23. The limiting rod 23 is set up to limit the movement of the protective frame 21.
[0022] The cutting mechanism includes a second motor 33, which is fixedly mounted on the support 7. The second motor 33 has forward and reverse rotation functions. The second motor 33 is used to drive the second lead screw 37 to rotate. The second lead screw 37 is fixedly mounted on the shaft end of the second motor 33. The second lead screw 37 is used to drive the first slider 36 to move. The first slider 36 is threadedly connected to the second lead screw 37. The first slider 36 is used to support the installation of the bracket 31. The bracket 31 is fixedly mounted on the top of the first slider 36. The bracket 31 is arched. The bracket 31 is used to support the installation of the first cylinder 32. The first cylinder 32 is fixedly mounted on the top of the bracket 31. The piston rod end of the first cylinder 32 passes through the bracket 31 and is fixedly mounted on the cutting machine. The first cylinder 32 is used to lift the cutting machine.
[0023] In detail, there are four columns 8, which are cylindrical rods. The columns 8 are set vertically and are used to support the installation of the support platform 7.
[0024] Furthermore, there are two limiting rods 23, both of which are cylindrical rods. The two limiting rods 23 are symmetrically arranged with the first lead screw 22 as the center. The setting of the limiting rods 23 serves to limit the movement of the protective frame 21.
[0025] Furthermore, a slide rod 34 is fixedly installed on the support platform 7, and a second slider 35 is slidably mounted on the slide rod 34. The second slider 35 is square in shape, and the bracket 31 is fixedly installed on the second slider 35. By setting the slide rod 34 and the second slider 35, when the first slider 36 drives the bracket 31 to move, the slide rod 34 serves to limit the movement of the bracket 31.
[0026] More specifically, the first slider 36 is horizontally positioned and is a square block in shape. The first slider 36 is positioned to support the installation of the bracket 31.
[0027] In general, a mounting bracket 5 is fixedly installed on the support 7. The mounting bracket 5 is L-shaped, and a second cylinder 6 is fixedly installed at the top of the mounting bracket 5. The mounting bracket 5 is designed to support the installation of the second cylinder 6.
[0028] Finally, the piston rod end of the second cylinder 6 penetrates the inner wall of the mounting bracket 5. Both the piston rod end of the second cylinder 6 and the support 7 are fixedly mounted with clamps 4. By setting clamps 4, in conjunction with the second cylinder 6, they are used to clamp and fix the bearing steel pipe.
[0029] Working method: During operation, both ends of the bearing steel tube are placed on the clamp 4 respectively. Then, the clamp 4 is lowered by the second cylinder 6 to clamp and fix the bearing steel tube. After clamping and fixing, the second motor 33 is started. The second motor 33 drives the second lead screw 37 to rotate. The second lead screw 37 drives the bracket 31 to move through the first slider 36. Under the limiting action of the second slider 35 and the slide bar 34, the bracket 31 will move linearly. When the bracket 31 moves linearly, it will drive the cutting machine to move through the first cylinder 32 until the cutting machine moves to the appropriate position. Then, the first motor 24 is started. The first motor 24 drives the first lead screw 22 to move. The first lead screw 22 drives the protective frame 21 to move vertically upward along the surface of the limiting rod 23 until the protective frame 21 moves to the appropriate height. Then, the cutting machine is started, and the cutting machine is lowered by the first cylinder 32 to cut the bearing steel tube. Since the protective frame 21 is transparent, it is easy to cut through the process.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
