[0033] Specifically, the I-shaped steel pipe that needs to be corrected is placed above the conveyor belt 6. By starting the DC motor 5, the cylinder 4 can be driven to rotate. As the cylinder 4 rotates, the outer conveyor belt 6 can be driven to rotate, so that the I-shaped steel pipe moves toward the correction area. At this time, the hydraulic rods 8 on both sides are started to drive the trapezoidal blocks 9 on both sides to move relative to each other. When the triangular extrusion blocks 10 contact the corners on both sides of the I-shaped steel pipe, as the hydraulic rods 8 are squeezed, the triangular extrusion blocks 10 on the same side will move relative to each other, thereby correcting the upper and lower sides of the I-shaped steel pipe that are prone to distortion, and the squeezing of the hydraulic rods 8 at any time will also correct the middle part of the I-shaped steel pipe.

[0034] Reference Figure 1 、 Figure 2 and Figure 5 The grinding mechanism 2 includes a servo motor 201, which is fixedly connected to the left rear portion of the groove base 1. The output end of the servo motor 201 passes through the groove base 1 and is fixedly connected to the first grinding rod 202.

The rear side of 05 is rotatably connected to a rotating plate 208, and the front bottom of the rotating plate 208 is rotatably connected to a winding pulley 207. The rear side of the rotating plate 208 is rotatably connected to a rotating bar 209.

A belt 210 is provided on the outer side of the first pulley 206 and the winding pulley 207; the rear side of the top first pulley 206 is rotatably connected to a sliding block 18, and the rear side of the groove base 1 is fixedly connected to a limiting plate 17. A sliding groove 19 is provided at the front end of the limiting plate 17, and the sliding block 18 is slidably connected to the sliding groove 19;

[0035] Specifically, by starting the servo motor 201, the first grinding rod 202 and the first pulley 206 above can be driven to rotate, and the outer belt 210 will also be driven by the first pulley 206 to rotate together. By starting the electric telescopic rod 203 to retract, the second grinding rod 205 will be driven to move to the bottom. At this time, the rotating bar 209 and the rotating plate 208 will bend to the right and drive the winding pulley 207 to move to the right, so that the belt 210 is always in a taut state, and the burrs or iron filings on the upper and lower sides of the I-shaped steel pipe can be polished off. The moving trajectory of the top first pulley 206 can be limited by the limit plate 17, and the movement of the first pulley 206 can be facilitated by the slide groove 19 and the sliding block 18.

[0036] Reference Figure 1 and Figure 2The top front part of the groove base 1 is fixedly connected to an alarm 12, and the left and right sides of the outer wall of the alarm 12 are fixedly connected to speakers 13; the top middle part of the groove base 1 is fixedly connected to a groove fixing column 14, and the right side of the groove fixing column 14 is slidably connected to a moving block 15, and a laser pen 16 is provided at the front end of the moving block 15, and the outer wall of the laser pen 16 passes through the moving block 15; the left side of the moving block 15 is fixedly connected to a fixing column 23, and the outer side of the fixing column 23 is threadedly connected to a fixing nut 24;

[0037] Specifically, the alarm 12 can be used to alert staff when a fault occurs, the laser pen 16 can be used to horizontally illuminate the calibrated steel pipe to observe whether there is any uncalibrated phenomenon, the height of the laser pen 16 can be adjusted by moving the moving block 15, and the adjusted position can be fixed by fixing the nut 24.

[0038] Reference Figure 1 、 Figure 2 and Figure 5 A controller 20 is fixedly connected to the right side of the top of the groove base 1, and the controller 20 is electrically connected to the DC motor 5, the hydraulic rod 8, the servo motor 201 and the electric telescopic rod 203 respectively; the outer side of the controller 20 is fixedly connected to the outer side of the housing 21, and the outer side of the housing 21 is rotatably connected to the protective cover 22;

[0039] Specifically, the controller 20 can control the starting and operating power between the DC motor 5, the hydraulic rod 8, the servo motor 201 and the electric telescopic rod 203 respectively. The shell 21 can prevent the controller 20 from being damaged due to bumps, and the protective cover 22 can prevent dust, iron filings, etc. from entering the controller 20 and causing damage to the internal electronic components.

[0040] Working principle: Before using the device, first, when performing the correction process, the I-shaped steel pipe to be corrected is placed above the conveyor belt 6, and then the DC motor 5 is started to drive the rotation of the cylinder 4. The rotation of the cylinder 4 will drive the outer conveyor belt 6 to move, and then the I-shaped steel pipe will move stably to the correction area. During this process, the hydraulic rods 8 on both sides are started at the same time to drive the trapezoidal blocks 9 on both sides to move relative to each other. When the triangular extrusion blocks 10 come into contact with the corners on both sides of the I-shaped steel pipe, as the hydraulic rods 8 are further squeezed, the triangular extrusion blocks 10 on the same side will move relative to each other, thereby accurately correcting the possible distortion on the upper and lower sides of the I-shaped steel pipe. At the same time, as the hydraulic rods 8 continue to squeeze, the middle part of the I-shaped steel pipe will also be corrected accordingly.

[0041] And through the grinding mechanism 2, starting the servo motor 201 will drive the first grinding rod 202 and the first pulley 206 above it to rotate. At the same time, due to the rotation of the first pulley 206, the outer belt 210 will also be driven to rotate synchronously. Then, by starting the contraction function of the electric telescopic rod 203, the second grinding rod 205 will move toward the bottom. During this process, the rotating bar 209 and the rotating plate 208 will bend to the right, thereby pushing the winding pulley 207 to move to the right. This series of actions ensures that the belt 210 is always kept taut, thereby effectively grinding the burrs or iron filings on the upper and lower sides of the I-shaped steel pipe.

[0042] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
