[0025] Sheets stacked from top to bottom are placed in hopper 12, supported by a lifting plate. The screw jack 11 gradually moves the lifting plate upward, lifting the top sheet to the picking position.

The multi-axis robotic arm can drive the suction cup to move horizontally left and right, horizontally forward and backward, and vertically. The suction cup is used to pick up the sheet.

[0027] The sheet initial winding mechanism 3 includes a lower die 31, a left die 32, a right die 33, a lower die lifting cylinder 34, a left die horizontal drive cylinder 35, and a right die horizontal drive cylinder 36. The lower die 31 has an arc-shaped groove at its top, and the front ends of the left die 32 and the right die 33 are also provided with arc-shaped grooves. The cylinder bodies of the lower die lifting cylinder 34, the left die horizontal drive cylinder 35, and the right die horizontal drive cylinder 36 are all fixed on the machine base 7.

The lower die 31 is located between the left die 32 and the right die 33.

[0028] The rolling and shaping mechanism 4 includes an upper mold 41, a second left mold 42, a second right mold 43, an upper mold lifting cylinder 44, a second left mold horizontal drive cylinder 45, and a second right mold horizontal drive cylinder 46. The bottom of the upper mold 41 is provided with an arc-shaped groove. (See attached image) Figure 3 As shown, the upper mold 41 has a protrusion 47 in the arc-shaped groove. The front ends of the left mold 42 and the right mold 43 are both provided with arc-shaped grooves. The cylinder bodies of the upper mold lifting cylinder 44, the left mold horizontal drive cylinder 45, and the right mold horizontal drive cylinder 46 are all fixed on the machine base 7. The upper mold 41 is fixed on the piston rod of the upper mold lifting cylinder 44, the left mold 42 is fixed on the piston rod of the left mold horizontal drive cylinder 45, and the right mold 43 is fixed on the piston rod of the right mold horizontal drive cylinder 46. The upper mold 41 is located between the left mold 42 and the right mold 43.

[0029] The punch lifting mechanism 6 is a cylinder, the cylinder body is fixed on the machine base 7, and the piston rod of the cylinder is fixed on the machine body of the punch rotating mechanism 9.

[0030] As attached Figure 2 As shown, the stripping mechanism 8 includes a push plate 81 and a push plate horizontal drive cylinder 82. The piston rod of the push plate horizontal drive cylinder 82 is fixed on the push plate 81, and the push plate 81 is provided with a through hole for passing through the columnar punch 5.

[0031] The punch rotation mechanism 9 is powered by a motor.

[0032] The working method of this application is as follows: First, the sheet material lifting and unloading mechanism 1 lifts a sheet material to the picking position, and then the sheet material transfer mechanism 2 places a sheet material horizontally onto the lower die 31. Next, the punch lifting mechanism 6 drives the columnar punch 5 to move downward, and the columnar punch 5 presses the sheet material into the arc-shaped groove of the lower die 31, thereby pressing the sheet material into a U-shape. At this time, the left die horizontal drive cylinder 35 and the right die horizontal drive cylinder 36 on the left and right sides respectively drive the left die 32 and the right die 33 to move horizontally toward the columnar punch 5, thereby initially rolling the sheet material into a circle and holding it with the columnar punch 5.

[0033] After the left mold 32 and right mold 33 release the cylindrical punch 5, the cylindrical punch 5, carrying the initially rolled workpiece, moves upward between the left mold 42 and right mold 43. The left mold 42 and right mold 43 are positioned relatively rearward, while the upper mold 41 is positioned relatively forward. At this time, the punch rotation mechanism 9 drives the cylindrical punch 5 and the workpiece on the cylindrical punch 5 to rotate, so that the part of the workpiece that needs to be flattened is aligned with the upper protrusion 47.

[0034] Then, the left mold horizontal drive cylinder 45 and the right mold horizontal drive cylinder 46 respectively drive the left mold 42 and right mold 43 on the left and right sides to clamp the workpiece. The workpiece is shaped by the arc-shaped grooves of the left mold 42 and right mold 43. Next, the upper mold lifting cylinder 44 drives the upper mold 41 to move down, and the workpiece is shaped by the arc-shaped groove of the upper mold 41. At the same time, the protrusion 47 in the arc-shaped groove of the upper mold 41 will flatten part of the workpiece. This completes the workpiece rolling operation.

[0035] Finally, the horizontal drive cylinder 82 drives the push plate 81 to move horizontally along the columnar punch 5, which can push the rolled workpiece away from the columnar punch 5.
