Through the foregoing solution, the problem that there is no positioning mechanism in the existing flanging device for sheet metal processing, and the sheet metal to be processed cannot be accurately placed on the upper surface of the lower die base 102, resulting in an unsatisfactory effect of flanging the sheet metal, is solved. It can be understood that the foregoing solution can be used in the structure of the flanging device for sheet metal processing.

[0028] For this specific embodiment, the lower die base 102 is arranged at the center of the upper surface of the workbench 101. The frame 103 is also arranged on the upper surface of the workbench 101. The hydraulic cylinder 104 is arranged at the top of the frame 103.

The auxiliary reinforcing ribs 122 are arranged in an inclined structure. The end of the auxiliary reinforcing rib 122 away from the mounting plate 105 is sleeved outside the support arm of the frame 103. Place the sheet metal to be processed on the upper surface of the lower die base 102. Start the hydraulic cylinder 104. Drive the upper die block 106 to move downward through the mounting plate 105, so as to perform flanging work on the sheet metal on the lower die base 102. After the flanging of the sheet metal is completed, start the electric push rod 107 to drive the lifting plate 108 to rise, so as to drive the pushing rods 109 to move upward. The upward movement of the pushing rods 109 can push the sheet metal stuck on the lower die base 102 off the lower die base 102. Through the arrangement of the auxiliary reinforcing ribs 122, the movement of the mounting plate 105 is made more stable.

[0029] Wherein, a positioning pointer 110 is provided at the center of the side surface of the lower die base 102. Two moving guide rails 111 are further installed on the upper surface of the workbench 101. The two moving guide rails 111 are respectively located on both sides of the lower die base 102. A sliding frame 112 is slidably arranged on each moving guide rail 111. A pushing component 113 is arranged inside each moving guide rail 111.

Inside each mounting hole 123, a ball 124 is provided. Through the arrangement of the mounting holes 123 and the balls 124, when the sliding seat 119 slides on the moving guide rail 111, the sliding is smoother. On each surface of each moving guide rail 111 close to the upper surface of the workbench 101, a fixed wing plate 125 is provided. The fixed wing plate 125 is detachably connected to the upper surface of the workbench 101. The fixed wing plate 125 is installed on the upper surface of the workbench 101 by using screws, thereby completing the installation of the moving guide rail 111.

[0033] When using a flanging device of this embodiment, a marking line is made at the center of the sheet metal part to be processed with a marker pen. After placing the sheet metal part to be processed on the lower die base 102, two pushing components 113 are synchronously started to drive the sliding frame 112 to slide on the corresponding moving guide rail 111, so that both positioning plates 115 move towards the lower die base 102, and the sheet metal part to be processed is firmly clamped by the two positioning plates 115. Then, according to the position of the marking line, the pushing component 113 is started to drive the sliding frame 112 to slide on the moving guide rail 111 to complete the adjustment of the position of the sheet metal part, so that the marking line on the sheet metal part corresponds to the positioning pointer 110 on the lower die base 102, thereby completing the positioning of the sheet metal part. The hydraulic cylinder 104 is started, and the upper module 106 is driven to move downward through the mounting plate 105, so as to perform the flanging work on the sheet metal part on the lower die base 102. After the flanging of the sheet metal part is completed, the electric push rod 107 is started to drive the lifting plate 108 to rise, thereby driving the push rod 109 to move upward. The upward movement of the push rod 109 can push the sheet metal part stuck on the lower die base 102 off the lower die base 102.
