Description

Technical Field

[0001] The utility model relates to the technical field of cold-rolled strip processing equipment, in particular to a fine grinding and deburring device based on the edge of cold-rolled strip steel. Background Art

[0002] Cold-rolled strip steel takes hot-rolled strip steel or steel plate as raw materials, and is rolled by a cold rolling mill at normal temperature to form a strip product with a thickness usually between 0.1 and 3 mm and a width between 100 and 2000 mm; this material has the characteristics of high surface finish, high dimensional accuracy, good mechanical properties, etc., and can be subjected to subsequent coating processing, etc. according to needs.

[0003] Refer to the patent name: A Cold-rolled Steel Strip Edge Trimming and Deburring Device (Patent Publication No.: CN218017583U, Patent Publication Date: December 13, 2022). There are multiple guide wheels on both sides below the support block for restricting the cold-rolled strip steel from shaking left and right. The first motor drives multiple guide wheels on both sides and two grinding components to move synchronously inward or synchronously outward through the first transmission component. There are fixing plates for fixing the cold-rolled strip steel on both sides below the upper support seat. When the steel strip is transported through the conveyor belt, it passes through between two of the four guide wheels. The guide wheels restrict the steel strip to move only in a straight line and will not deviate left and right during the movement. Moreover, the guide wheels and the two grinding components are simultaneously adjusted through the first motor cooperating with the first transmission component. The distance between the guide wheels is the same as the distance between the grinding components, and no separate adjustment is required. When grinding is needed, the fixing plates arranged on both sides above the conveyor belt can be lowered to fix the steel strip to prevent the steel strip from moving during grinding and affecting the grinding process.

[0004] However, when implementing the above technical solutions, there are the following problems: The above solutions can realize the movement of the cold-rolled strip during the grinding process on a certain track. However, in the above solutions, there are many assembly control motors in the device and it is difficult to grind the edge position of the cold-rolled strip. In the above solutions, the upper surface of the cold-rolled strip is restricted and ground by the guide wheels that move synchronously with the grinding wheels. However, it can only achieve a good grinding effect on the edge surface of the cold-rolled strip. It is difficult to ensure the grinding effect at the corner and the side of the edge of the cold-rolled strip at the corner position. Therefore, after single-sided grinding, manual flipping may be required for re-grinding. For this reason, the utility model provides a fine grinding and deburring device based on the edge of cold-rolled strip steel. Summary of the Utility Model

A moving assembly 5 is arranged between the grinding block 31 and the moving block 34 to realize position change. The surface of the moving block 34 also fixes the grinding paper 33 through the fixing assembly 4. Both the grinding block 31 and the moving block 34 are L-shaped blocks. After the sandpaper is fixed on their surfaces, it can form a corner to grind the corners of cold-rolled strip steel. An operating assembly is arranged between the grinding blocks 31 to realize the change of distance;

[0029] An operating assembly, which is arranged inside the precision grinding table 1 to realize the horizontal distance adjustment.

[0030] Inside the fine grinding table 1, multiple conveyor belts 2 are arranged. A fixed grinding disc 32 is arranged between the conveyor belts 2. Through the grinding disc 32, the grinding of the lower surface of the cold-rolled strip conveyed on the surface of the conveyor belt 2 can be realized. And inside the fine grinding table 1, a movable block 34 and a grinding block 31 whose positions can be adjusted are arranged. The two form a C-shaped structure.

And the distance is adjusted by the electric telescopic rod 37, and the adjustment is more convenient.

[0031] Embodiment 2

[0032] The main difference from Embodiment 1 is that:

[0033] Based on the fine grinding and deburring device for the edge of cold-rolled strip steel, the fixing component 4 includes a fixing block 41 that slides inside the grinding block 31. A fixing rack 42 is fixedly connected to the surface of the fixing block 41. A fixing gear 43 is slidably arranged inside the grinding block 31. The surface of the fixing gear 43 meshes with the surface of the fixing rack 42. A fixing ring 44 is fixedly connected inside the grinding block 31. Teeth are fixedly connected inside the fixing ring 44. The fixing gear 43 can slide and rotate inside the grinding block 31. The surface of the fixing gear 43 meshes with the surface of the fixing rack 42. When the fixing gear 43 slides outwards, the surface of the fixing gear 43 can simultaneously mesh with the surface of the fixing rack 42 and the teeth inside the fixing ring 44. The moving component 5 includes a moving rod 51 and a limiting rod 52 that rotate inside the grinding block 31. The surface of the moving rod 51 is threadedly connected to the inside of the moving block 34. A limiting spring 53 is fixedly connected between the limiting rods 52. The surface of the limiting rod 52 has a relatively large frictional contact with the surface of the moving rod 51, which will limit the rotation of the moving rod 51. The sliding component 6 includes a sliding shaft 61 fixed on the surface of the acting block 34. A sliding groove 62 is opened on the surface of the grinding block 31. The surface of the sliding shaft 61 is slidably connected to the inner surface of the sliding groove 62. A fixing block 41 that can slide is arranged inside the grinding block 31. By the contact between one end of the abrasive paper 33 and the fixing block 41, the fixing block 41 can be driven to move and ensure that the surface of the abrasive paper 33 is in close contact with the surface of the fixing block 41. Then, after restricting the movement between the fixing blocks 41, the abrasive paper 33 can be fixed on the surface of the grinding block 31. A fixing rack 42 is arranged on the surface of the fixing block 41. A fixing gear 43 that can slide is arranged between the fixing rack 42 and the fixing ring 44. After the fixing gear 43 slides and is fixed with the fixing ring 44, it can cause the fixing rack 42 to stop moving. The operation is simple and fast.

[0034] At the same time, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] During operation, first, an appropriate number of abrasive papers 33 are fixed to the surfaces of the abrasive block 31 and the moving block 34. One end of the abrasive paper 33 is inserted into the interiors of the abrasive block 31 and the moving block 34. The insertion of the abrasive paper 33 will cause the fixed block 41 to move, and further cause the fixed rack 42 to slide, prompting the fixed gear 43 to rotate. After the position of the abrasive paper 33 is determined, the fixed gear 43 is slightly rotated to cause the fixed rack 42 to move towards the position of the abrasive paper 33. Then, the fixed gear 43 is pulled so that the surface of the fixed gear 43 meshes with both the fixed rack 42 and the interior of the fixed ring 44 simultaneously, restricting the rotation of the fixed gear 43. At this time, the abrasive paper 33 is fixed. Then, the position of one end of the electric telescopic rod 37 is adjusted according to the width of the cold-rolled strip. The change in the position of the electric telescopic rod 37 will cause the acting rod 36 to rotate, and further drive the acting block 35 to slide inside the abrasive block 31 and cause the abrasive block 31 to move. After the distance between the two is determined, the limiting rod 52 is squeezed, causing the surface of the limiting rod 52 to disengage from the surface of the moving rod 51. At this time, the moving rod 51 can be rotated to drive the moving block 34 to slide inside the abrasive block 31 to adjust the position of the moving block 34. When the distance between the abrasive paper 33 between the two is the same as the height of the cold-rolled strip, the limiting rod 52 can be released. Then, the cold-rolled strip is passed through the moving block 34 and the abrasive block 31, and one end is placed on the surface of the front conveyor belt 2, and the conveyor belt 2 can be driven to perform subsequent grinding.
