[0003] Currently, existing technologies have significant drawbacks in deburring and protecting the bent edges of galvanized sheets. The deburring process and the protective coating application process are often independent of each other, requiring the deburred galvanized sheet to be transferred to another station for coating. This not only increases the complexity of the production process but also leads to low production efficiency, making it difficult to meet the production needs of small batches and multiple production runs of customized sheet metal parts. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a deburring device for bending the edge of galvanized sheet, so as to solve the problems mentioned in the background art.

Detailed Implementation

[0022] Example

[0023] refer to Figures 1 to 6 This embodiment describes a deburring device for bending the edges of galvanized steel sheets, comprising a base 1. A repositioning component 11 is provided on one side of the base 1. A movable seat 2 is slidably connected to one side of the base 1 via the repositioning component 11. A first cylinder 4 is fixedly connected to one side of the movable seat 2. An assembly plate 3 is fixedly connected to the output end of the first cylinder 4. A first motor 5 is fixedly connected to the side of the assembly plate 3 away from the first cylinder 4. A grinding disc 6 is fixedly connected to the output end of the first motor 5. An air guide frame 8 is fixedly connected to the side of the assembly plate 3 located on the grinding disc 6. A fan 7 is fixedly connected to one side of the air guide frame 8. A coating component 10 is provided on one side of the assembly plate 3 located on the air guide frame 8. A feeding component 9 is provided on one side of the coating component 10. A positioning frame 12 is fixedly connected to the base 1 on the opposite side of the movable seat 2. The assembly plate 3 is moved by the first cylinder 4. The assembly plate 3 consists of three plates, which are respectively connected to the first motor 5 and the grinding disc 6, the fan 7 and the air guide frame 8, the feeding component 9 and the coating component 10, so as to facilitate approaching or contacting the galvanized sheet. The positions of these structures are adjusted by the repositioning component 11 to facilitate the processing of the galvanized sheet.

[0024] refer to Figures 2-4The feeding assembly 9 includes a feeding pump 91, which is fixedly connected to the side of the assembly plate 3 away from the coating assembly 10. A feeding pipe 92 is fixedly connected to the input end of the feeding pump 91, and a conveying pipe 93 is fixedly connected to the output end of the feeding pump 91. A spray head 94 is fixedly connected to one side of the conveying pipe 93, and the spray head 94 is close to the coating assembly 10. A guide frame 95 is fixedly connected to the side of the spray head 94 away from the conveying pipe 93 and close to the coating assembly 10. The inner wall is inclined; by setting the feeding component 9, the feeding pipe 92 is connected to the external protective coating storage container. After the feeding pump 91 is started, the protective coating is sucked in from the feeding pipe 92 and transported to the spray head 94 through the conveying pipe 93. The spray head 94 sprays out the coating. Since the inner wall of the guide frame 95 is inclined, the coating can be guided to flow towards the vicinity of the coating component 10, avoiding coating splashing and waste. By supplying coating immediately after deburring, the problems of easy rusting of edges after grinding and friction damage during subsequent assembly can be solved.

[0025] refer to Figure 4-5 The coating assembly 10 includes a first fixing plate 101, which is fixedly connected to the assembly plate 3 on both sides of the material conveying tube 93. A second fixing plate 102 is provided on the side of the first fixing plate 101 away from the assembly plate 3. A second motor 103 is fixedly connected to the top of the second fixing plate 102. A coating roller 104 is fixedly connected to the output end of the second motor 103. A spring 105 is fixedly connected between the first fixing plate 101 and the second fixing plate 102. A guide rod 106 is fixedly connected between the two springs 105 and the second fixing plate 102. One side of the guide rod 106 slides through the second fixing plate 102. By setting up the coating component 10, the second motor 103 starts, driving the coating roller 104 with coating material to rotate. The rotating coating roller 104 evenly applies the coating material to the bent edge of the galvanized sheet, achieving uniform application of protective coating, effectively covering the edge of the galvanized sheet after grinding, and enhancing the edge's rust prevention and friction resistance. During the coating process, when the surface of the galvanized sheet is uneven, the second fixing plate 102 can move in a small range along the extension and contraction direction of the spring 105 under the guidance of the guide rod 106. The elasticity of the spring 105 enables the coating roller 104 to adapt to the galvanized sheet with different surface conditions, ensuring that the coating roller 104 and the surface of the galvanized sheet always maintain a suitable contact pressure.

[0026] refer to Figure 1The repositioning component 11 includes a third motor 111, which is fixedly connected to one side of the base 1. A first gear 112 is fixedly connected to the output end of the third motor 111. A second gear 113 is meshed with one side of the first gear 112. A lead screw 114 is fixedly connected to one side of the second gear 113. The movable seat 2 is threadedly connected to the lead screw 114. A sliding groove 115 is provided inside the base 1. The lead screw 114 is rotatably connected inside the sliding groove 115. One side of the movable seat 2 is slidably connected to the sliding groove 115. By setting the repositioning component 11, the third motor 111 drives the first gear 112 to rotate, and the first gear 112 drives the second gear 113 to rotate. Since the movable seat 2 is threadedly connected to the lead screw 114, when the lead screw 114 rotates, the movable seat 2 slides in the sliding groove 115 along the direction of the lead screw 114. The position of the movable seat 2 can be flexibly adjusted according to the size and bending position of the galvanized sheet, and then moved to a suitable processing position.

[0027] refer to Figure 6 The top end of the positioning frame 12 is fixedly connected to a second cylinder 13, and the output end of the second cylinder 13 is fixedly connected to a pressing block 14. The pressing block 14 is movably connected to the inner side of the positioning frame 12. By setting the second cylinder 13 and the pressing block 14, the second cylinder 13 pushes the pressing block 14 to fix the galvanized sheet, ensuring the stability of the galvanized sheet during the processing.

[0028] Operating principle and advantages: First, the galvanized sheet is placed inside the positioning frame 12 of the base 1. The second cylinder 13 at the top of the positioning frame 12 is activated, pushing the clamping block 14 downward to firmly fix the galvanized sheet, ensuring that it will not shake during processing. The third motor 111 drives the first gear 112 to rotate, which in turn causes the meshing second gear 113 to rotate. The lead screw 114 connected to the second gear 113 rotates accordingly. Since the moving seat 2 is threadedly connected to the lead screw 114, the lead screw 11... 4. During rotation, the movable seat 2 slides along the screw 114 in the groove 115 of the base 1, thereby moving the entire processing assembly to the appropriate processing position. The first cylinder 4 pushes the assembly plate 3, composed of three plates, close to the galvanized sheet. First, the first motor 5 drives the grinding disc 6 to rotate at high speed to grind and deburr the bent edges of the galvanized sheet. After grinding, the fan 7 starts, and the generated airflow is blown directionally towards the galvanized sheet through the air guide frame 8 to clean away the dust, debris, and other impurities remaining after grinding. Then, the feed pipe... 92 connects to the external protective coating storage container. The feed pump 91 starts, drawing the protective coating from the feed pipe 92 and conveying it to the spray head 94 through the conveying pipe 93. The spray head 94 sprays the coating out, and under the guidance of the inclined inner wall of the feed frame 95, the coating flows towards the vicinity of the coating assembly 10. At this time, the second motor 103 of the coating assembly 10 starts, driving the coating roller 104 to rotate. The rotating coating roller 104 evenly coats the coating on the bent edge of the galvanized sheet. When the surface of the galvanized sheet is uneven, the second fixed plate 102 in the coating assembly 10 moves slightly under the guidance of the guide rod 106 and the elastic action of the spring 105, so that the coating roller 104 adaptively conforms to the surface of the galvanized sheet, maintaining appropriate contact pressure to ensure uniform coating. Through the above working steps, the device realizes the integrated processing of two key processes: deburring the bent edge of the galvanized sheet and applying the protective coating. There is no need to transfer the workpiece, completely eliminating the handling and waiting links between traditional processes, significantly reducing the complexity of operation, and greatly improving production efficiency.
