Then, the first hydraulic rod 3 is activated, clamping the steel pipe using the clamps 2. Next, the second hydraulic rod 4 is activated, moving the mold 5 at its output end. At this time, the cleaning device 6 cleans the outer surface of the mold 5, and then the mold 5 contacts the inner or outer wall of the steel pipe, thus expanding or reducing the diameter of the steel pipe.

[0022] Figures 1 to 5 The cleaning device 6 shown includes a mounting assembly 61, a mounting frame 62, a motor 63, a gear 64, a cleaning brush 65, and a toothed ring 66. The mounting assembly 61 is located on one side of the base 1 and is used to install and fix the mounting frame 62. The motor 63 is located on one side of the mounting frame 62, and the gear 64 is located at the output end of the motor 63. The cleaning brush 65 is located on one side of the mounting frame 62 and is supported by the mounting frame 62. The toothed ring 66 is located on the outer wall of the cleaning brush 65 and meshes with the gear 64. The gear 64 drives the cleaning brush 65 to rotate through the toothed ring 66.

[0023] Figures 1 to 5When using the cleaning device 6, the mounting assembly 61 fixes the placement frame 62 to one side of the base 1. Then, the motor 63 fixed to one side of the placement frame 62 is started, causing the gear 64 fixed at the output end of the motor 63 to rotate. Then, the gear 64 drives the meshing gear ring 66 to rotate, and then the gear ring 66 drives the cleaning brush 65 fixed to one side to rotate. At this time, the cleaning brush 65 slides on one side of the placement frame 62, and then the cleaning brush 65 cleans the outer surface of the moving mold 5. By using the cleaning device 6, the debris adhering to the outer surface of the mold 5 can be cleaned to avoid friction damage to the steel pipe caused by the debris adhering to the outer surface of the mold 5, thereby improving the use effect of the steel pipe diameter expansion and contraction processing device.

[0024] Figures 1 to 5 The mounting assembly 61 shown includes a mounting block 611 and a bolt 612. The mounting block 611 is located on one side of the base 1, and the bolt 612 is inserted into one side of the mounting block 611 and threadedly fixed to the placement frame 62. When using the mounting assembly 61, the placement frame 62 can be inserted into the mounting block 611 fixed on one side of the base 1, and then the bolt 612 can be rotated to insert the bolt 612 into the mounting block 611 and threadedly fix it to the placement frame 62. This quickly fixes the placement frame 62 in place. By using the mounting assembly 61, the placement frame 62 can be quickly fixed to one side of the base 1, making it convenient for operators to use the cleaning brush 65 subsequently.

[0025] Figures 1 to 5 The bolt 612 shown has several anti-slip blocks 613 on one side to increase the friction on that side. By fixing the bolt 612 to one side with these anti-slip blocks 613, the friction on that side is increased, making it easier for the operator to rotate the bolt 612. Guide plates 614 are inclinedly arranged on both sides of the mounting block 611 to increase the size of the entrance on one side of the mounting block 611. By fixing the guide plates 614 inclinedly to one side of the mounting block 611, the size of the entrance on one side of the mounting block 611 is increased, making it easier for the placement rack 62 to be inserted into the mounting block 611.

[0026] Figures 1 to 5 The mounting bracket 62 shown has an arc-shaped strip 67 on the side near the cleaning brush 65. The arc surface of the arc-shaped strip 67 is close to the cleaning brush 65 to reduce the contact area between the mounting bracket 62 and the cleaning brush 65. By fixing the mounting bracket 62 to the side near the cleaning brush 65 with the arc surface of the arc-shaped strip 67 close to the cleaning brush 65, the contact area between the mounting bracket 62 and the cleaning brush 65 is reduced, making it easier for the cleaning brush 65 to rotate.

[0027] Figures 1 to 5A collection component 7 is provided on one side of the placement rack 62 shown. The collection component 7 includes a fan 71, an air inlet pipe 72, and a cloth bag 73.

The cloth bag 73 is located on the same side of the fan 71 to collect debris. When the cleaning brush 65 cleans debris from the surface of the mold 5, the fan 71 fixed on one side of the placement rack 62 is activated, causing the air inlet pipe 72 fixed on the same side of the fan 71 to suck the debris into the fan 71. Then, the debris is transported into the cloth bag 73, which is detachably fixed on the side of the fan 71, for collection. When the cloth bag 73 is full, it is removed and cleaned. By using the collection component 7, the debris cleaned by the cleaning device 6 can be adsorbed and collected, preventing the debris from returning to the surface of the mold 5, thereby improving the effectiveness of the cleaning device 6.

[0028] Figures 1 to 5 The placement rack 62 shown has a support plate 74 on one side, which is connected to the air inlet pipe 72 to support it. The air inlet pipe 72 is supported by fixing the support plate 74 to the air inlet pipe 72 and the placement rack 62, so that the air inlet pipe 72 can be used more stably.

[0029] Working principle: When processing the steel pipe, the steel pipe is placed in the two clamps 2 of the base 1, and then the first hydraulic rod 3 is activated to clamp the steel pipe through the clamps 2. Then the second hydraulic rod 4 is activated to move the mold 5 at the output end of the second hydraulic rod 4. At this time, the cleaning device 6 cleans the outer surface of the mold 5, and then the mold 5 is brought into contact with the inner or outer wall of the steel pipe to expand or reduce the diameter of the steel pipe. When using the cleaning device 6, the mounting assembly 61 fixes the placement frame 62 to one side of the base 1. Then, the motor 63 fixed to one side of the placement frame 62 is started, causing the gear 64 fixed at the output end of the motor 63 to rotate. Then, the gear 64 drives the meshing gear ring 66 to rotate, and then the gear ring 66 drives the cleaning brush 65 fixed to one side to rotate. At this time, the cleaning brush 65 slides on one side of the placement frame 62, and then the cleaning brush 65 cleans the outer surface of the moving mold 5. By using the cleaning device 6, the debris adhering to the outer surface of the mold 5 can be cleaned to avoid friction damage to the steel pipe caused by the debris adhering to the outer surface of the mold 5, thereby improving the performance of the steel pipe diameter expansion and contraction processing device.

[0030] When the cleaning brush 65 cleans the surface of the mold 5, the fan 71 fixed on one side of the placement rack 62 is started, and the air inlet pipe 72 fixed on one side of the fan 71 sucks the debris into the fan 71. Then the debris is transported into the cloth bag 73 that is detachably fixed on one side of the fan 71 for collection. After the cloth bag 73 is full, the cloth bag 73 is removed for cleaning. By using the collection component 7, the debris cleaned by the cleaning device 6 can be adsorbed and collected, preventing the debris from returning to the surface of the mold 5, thereby improving the effectiveness of the cleaning device 6.
