Description
Technical Field
[0001] This utility model relates to the field of sheet metal processing technology, and more specifically to a cold sheet metal surface polishing device. Background Technology
[0002] Cold-rolled steel sheet, also known as cold-rolled steel plate, is a metal sheet made from hot-rolled steel coils at room temperature. Cold-rolled steel sheets can be classified by thickness into thin sheets (less than 4mm), medium sheets (4-20mm), and thick sheets (over 20mm). They can also be classified by material into ordinary carbon structural steel, low-alloy high-strength steel, alloy structural steel, and stainless steel. Finally, they can be classified by surface treatment into galvanized sheets, aluminized zinc sheets, and color-coated sheets. When surface-treating cold-rolled steel sheets, polishing is usually required to reduce surface roughness and achieve a bright and smooth surface. The main purpose of polishing is to achieve a smooth or mirror-like finish, and sometimes it is also used to eliminate gloss (matte finish).
[0003] Existing cold plate surface polishing equipment typically uses a conveyor belt to move the cold plate in conjunction with a polishing cylinder for polishing. However, since the thickness of the cold plate varies, the equipment needs to be adjusted cumbersomely every time a different size of cold plate is replaced, making it inconvenient to use. Secondly, there is usually no fixing mechanism for the cold plate when it is transported on the conveyor belt, and the polishing force or equipment vibration may cause the cold plate to shift, affecting the polishing process.

[0012] The technical effects and advantages of this utility model are as follows:
[0013] This utility model features an adjustment mechanism. By rotating the adjustment handwheel, the adjustment rod rotates, which in turn moves the moving part up and down.

Loosening the fastening nut allows the position of the lifting rod to be moved. The height of the workpiece pressure roller can be adjusted according to the thickness of the workpiece. When a higher adjustment is needed, the fastening nut below the limiting component is rotated downwards to loosen it, and the lifting rod is moved upwards, causing the lifting plate to move upwards within the connecting plate. This, in turn, causes the pressure roller and the workpiece pressure roller to move upwards. When the appropriate height is reached, the fastening nut below the limiting component is rotated upwards to tighten it, and the fastening nut above is tightened simultaneously. This allows for adjustment of the workpiece pressure roller height according to the thickness of the cold plate, ensuring that the cold plate is fixed in place during polishing and preventing it from shifting and affecting the polishing effect.

By rotating the adjustment handwheel 403, the adjustment rod 402 is rotated, thereby driving the movable component 404 to move up and down. In turn, the mounting plate 405 and the polishing mechanism 3 move up and down to adjust the distance between the polishing sand belt 305 and the conveyor belt 203, so that it can adapt to the polishing of cold plates of different thicknesses.

[0028] In a preferred embodiment, the pressure roller assembly 5 includes a connecting plate 501, a groove is provided in the center of the front of the connecting plate 501, a lifting plate 502 is movably connected inside the groove of the connecting plate 501, slide bars are fixedly connected to the center of both sides of the lifting plate 502, a fixing member 503 is fixedly connected to the center of the front of the lifting plate 502 near the top, and a lifting rod 504 is fixedly connected to the inside of the front of the fixing member 503.
[0029] In a preferred embodiment, the lifting rod 504 is threaded on its outer side. A limiting member 505 is movably sleeved on the outer side of the lifting rod 504 near its top position. Fastening nuts 506 are movably connected to the top and bottom positions of the lifting rod 504 at the limiting member 505. A pressure roller 507 is fixedly connected to the bottom of the center of the front of the lifting plate 502. A workpiece pressure roller 508 is movably sleeved on the outer side of the pressure roller 507. The pressure roller assembly 5 is fixed by installing the connecting plate 501 on the support body 301. Loosening the fastening nuts 506 allows the lifting rod 504 to move, adjusting its position according to the thickness of the workpiece. The height of the workpiece pressure roller 508 can be adjusted. When it needs to be raised, the fastening nut 506 below the limiting piece 505 is turned downwards to loosen it. The lifting rod 504 can be moved upwards, which drives the lifting plate 502 to move upwards within the connecting plate 501. This, in turn, drives the pressure roller 507 and the workpiece pressure roller 508 to move upwards. When the appropriate height is reached, the fastening nut 506 below the limiting piece 505 is turned upwards to tighten it. The fastening nut 506 above is tightened simultaneously. This allows the height of the workpiece pressure roller 508 to be adjusted according to the thickness of the cold plate, thus fixing the cold plate in place during polishing and preventing the cold plate from shifting and affecting the polishing effect.
[0030] The working principle of this utility model:
[0031] Rotating the adjusting handwheel 403 causes the adjusting rod 402 to rotate, thereby moving the moving part 404 up and down. This, in turn, moves the mounting plate 405 and the polishing mechanism 3 up and down, adjusting the distance between the polishing belt 305 and the conveyor belt 203. This allows for the adjustment of the distance between the belt and the conveyor belt 203, adapting to polishing cold plates of different thicknesses. This facilitates quick adjustment of the height of the polishing belt 305, reducing tedious adjustment steps and improving efficiency. As the polishing belt 305 wears down with use, abrasive particles fall off, causing the belt to thin, shorten its circumference, and increase tension. Rotating the adjusting knob 3024 adjusts the belt... The adjusting rod 3023 rotates within the support member 3026, simultaneously driving the driving member 3022 on the adjusting rod 3023 to move up and down, thereby driving the tensioning block 3021 to move up and down, which in turn drives the roller shaft 303 and roller 304 to move up and down to adjust the tension of the polishing belt 305. After adjustment, the fixing nut 3025 is rotated to tighten the fixing nut 3025 and the support member 3026 relative to each other, thereby preventing the adjusting rod 3023 from rotating, and consequently preventing the tensioning block 3021 from moving, so that the tensioning block 3021 will not rebound after adjustment.
[0032] By installing the connecting plate 501 on the bracket body 301 to fix the pressure roller assembly 5, the position of the lifting rod 504 can be moved by loosening the fastening nut 506. The height of the workpiece pressure roller 508 can be adjusted according to the thickness of the workpiece. When it is necessary to raise it, the fastening nut 506 below the limiting piece 505 is turned downwards to loosen it, which moves the lifting rod 504 upwards, causing the lifting plate 502 to move upwards within the connecting plate 501, and then causing the pressure roller 507 and the workpiece pressure roller 508 to move upwards. When the appropriate height is reached, the fastening nut 506 below the limiting piece 505 is turned upwards to tighten it, and the fastening nut 506 above is tightened simultaneously. This is beneficial for adjusting the height of the workpiece pressure roller 508 according to the thickness of the cold plate, so that the cold plate is fixed in its state during polishing, and the cold plate is prevented from shifting and affecting the polishing effect.
[0033] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
