The second cylinder 1110 can push the rectangular sheets 600 to the upper part of the storage space until the pressure sensor 1120 detects pressure, proving that the rectangular sheets 600 have reached the specified position. Then the first cylinder 1100 works to push the uppermost rectangular sheet 600 into the trough 111 through the feed channel 190, so that the rectangular sheets 600 in the storage structure 180 automatically enter the trough 111 and are transported to the stamping mechanism with the help of the pusher 120 to complete automatic loading without manual operation, thereby improving the efficiency and safety of feeding.

[0053] Then, the first motor 140 drives the screw to rotate, which can drive the slider 160 to slide along the guide rail, and can control the movement of the pusher 120 in the material trough 111. The movement of the pusher 120 can be controlled by controlling the rotation of the motor to realize automatic feeding of the sheet material 600.

The sheet material 600 on the first lower die 240 is cut into pieces again, the stamping plate 220 is lifted, and the conveying mechanism works to synchronously move multiple sheets to the next position until they reach the fourth lower die 2100. The work of the stamping mechanism is specifically that the conveying mechanism moves the cut sheet to the second lower die 260, and then the stamping plate 220 moves toward the direction close to the workbench 210 until the second upper die 250 and the second lower die 260 contact, and the T-shaped protrusion 251 on the second upper die 250 is embedded in the sheet, and the oil groove is punched onto the sheet. The limiting component ensures the position of the sheet on the second lower die 260, ensures the accuracy of the position of the oil groove, and reduces the probability of forming scrap.

[0055] The conveying mechanism then moves the sheet further to the third lower punch 280, and then the stamping plate 220 moves toward the workbench 210 until the third upper punch 270 and the third lower punch 280 contact, cutting the two long sides of the sheet flat to ensure the flatness of both sides after the bushing is formed.
