[0015] A method for using a shearing and curling device for metal product processing comprises the following steps:

[0016] Step 1: Perform the hemming work, place the annular workpiece on the top of the carrier plate, pull the square rod to make the bottom of the outer wall of the hemming roller fit on the top of the annular workpiece, start the forward and reverse motors, the forward and reverse motors drive the rotating shaft to rotate, the rotating shaft drives the carrier plate to rotate, the carrier plate drives the annular workpiece to rotate, and the annular workpiece contacts the bottom of the hemming roller during the rotation process;

[0017] Step 2: Extrusion and lamination. The bending rod drives the rotating plate to move toward the inside of the arc-shaped shell. The rotating plate drives the lifting block to vertically descend along the inner wall of the vertical groove due to the limitation of the vertical groove. The lifting block drives the connecting rod to descend. The connecting rod drives the concave rod to descend. The concave rod drives the connecting frame to descend. The connecting frame drives the lower pressing plate to descend. The lower pressing plate will contact the top of the hemming roller during the descent process.

[0018] Step three: Auxiliary curling. When the lifting block moves downward, the lifting block drives the vertical rod to descend, and the vertical rod drives the piston plate to descend. The piston plate descends on the inner wall of the arc shell, so that the airflow inside the arc shell enters the elastic tube, and the airflow enters the extrusion shell through the elastic tube. After the airflow enters the extrusion shell, the lifting plate inside the extrusion shell moves upward, and the lifting plate drives the round rod to move upward, and the round rod drives the arc-shaped semi-circular rod to move upward. During the upward movement of the arc-shaped semi-circular rod, it will fit with the edge of the annular workpiece and move upward.

[0019] The present invention has the following beneficial effects:

[0020] (1) According to the present invention, the annular workpiece is placed on the top of the carrying plate, the square rod is pulled, so that the bottom of the outer wall of the curling roller is fitted on the top of the annular workpiece, and the forward and reverse motors are started. The forward and reverse motors drive the rotating shaft to rotate, the rotating shaft drives the carrying plate to rotate, and the carrying plate drives the annular workpiece to rotate. During the rotation of the annular workpiece, it contacts with the bottom of the curling roller, so that the annular workpiece performs curling during the rotation. At the same time, the rotating shaft drives the belt to rotate, and the belt drives the rotating screw to rotate. The rotating screw is limited by the limiting rod, and the rotating screw drives the threaded plate to vertically descend along the outer wall of the limiting rod. The threaded plate drives the conical part to descend. During the descent of the conical part, it contacts one side of the outer wall of the arc shell, squeezes the arc shell, and makes multiple arc shells move away from each other. The arc shell drives the bending rod to move, and the bending rod drives the extrusion shell to move. Multiple extrusion shells move away from each other, so that the inner wall of the annular workpiece can be supported and moved, thereby improving the stability of the annular workpiece driven by the carrying plate to rotate and improving the curling effect of the annular workpiece.

[0021] (2) According to the present invention, when the extrusion shell contacts the annular workpiece, the extrusion shell is prevented from over-extruding the annular workpiece and causing damage to the annular workpiece. The extrusion shell drives the bending rod to move toward the inside of the arc shell, thereby improving the protective effect of the curling of the annular workpiece. The bending rod drives the rotating plate to move toward the inside of the arc shell. Limited by the vertical groove, the rotating plate drives the lifting block to vertically descend along the inner wall of the vertical groove. The lifting block drives the connecting rod to descend. The connecting rod drives the concave rod to descend. The concave rod drives the connecting frame to descend. The connecting frame drives the lower pressure plate to descend. During the descending process, the lower pressure plate will contact the top of the curling roller, thereby making the curling roller further fit with the top of the annular workpiece, thereby improving the curling effect of the curling roller on the annular workpiece.

[0022] (3) According to the present invention, when the lifting block moves downward, the lifting block drives the vertical rod to move downward, and the vertical rod drives the piston plate to move downward. The piston plate moves downward on the inner wall of the arc shell, so that the airflow inside the arc shell enters the elastic tube, and the airflow enters the extrusion shell through the elastic tube. After the airflow enters the extrusion shell, the lifting plate inside the extrusion shell moves upward, and the lifting plate drives the round rod to move upward, and the round rod drives the arc-shaped semi-circular rod to move upward. During the upward movement of the arc-shaped semi-circular rod, it will fit with the edge of the annular workpiece at the curling place and move upward, thereby preventing the angle after curling from being inconsistent with the preset standard, and making the angle after curling the same as the arc angle of the arc-shaped semi-circular rod, thereby improving the work quality of curling the annular workpiece. At the same time, when the arc-shaped semi-circular rod drives the annular workpiece to move upward, it can make the annular workpiece further fit with the bottom of the outer wall of the curling roller, thereby further improving the stability of the curling of the annular workpiece.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] A method for using a shearing and curling device for metal product processing comprises the following steps:

[0047] Step 1: Perform the curling work, place the annular workpiece 552 on the top of the carrier plate 551, pull the square rod 554, make the outer wall bottom of the curling roller 556 fit on the top of the annular workpiece 552, start the forward and reverse motor 51, the forward and reverse motor 51 drives the rotating shaft 59 to rotate, the rotating shaft 59 drives the carrier plate 551 to rotate, the carrier plate 551 drives the annular workpiece 552 to rotate, and the annular workpiece 552 contacts the bottom of the curling roller 556 during the rotation process;

[0048] Step 2: Extrusion and lamination. The bending rod 565 drives the rotating plate 571 to move toward the inside of the arc-shaped shell 564. The rotating plate 571 is limited by the vertical slot 572. The lifting block 573 drives the connecting rod 574 to move downward along the inner wall of the vertical slot 572. The lifting block 573 drives the connecting rod 574 to move downward. The connecting rod 574 drives the concave rod 576 to move downward.

The lower pressing plate 578 will contact the top of the hemming roller 556 during the descending process.

[0049] Step three: Auxiliary curling. When the lifting block 573 moves downward, the lifting block 573 drives the vertical rod 581 to descend, and the vertical rod 581 drives the piston plate 582 to descend. The piston plate 582 descends on the inner wall of the arc shell 564, so that the airflow inside the arc shell 564 enters the elastic tube 584, and the airflow enters the extrusion shell 566 through the elastic tube 584. After the airflow enters the extrusion shell 566, the lifting plate 585 inside the extrusion shell 566 moves upward, and the lifting plate 585 drives the round rod 586 to move upward, and the round rod 586 drives the arc-shaped semi-circular rod 587 to move upward. During the upward movement, the arc-shaped semi-circular rod 587 will fit with the edge of the annular workpiece 552 and move upward.

[0050] When in use, the annular workpiece 552 is placed on the top of the carrying plate 551, and the square rod 554 is pulled to make the bottom of the outer wall of the curling roller 556 fit the top of the annular workpiece 552, and the forward and reverse motors 51 are started. The forward and reverse motors 51 drive the rotating shaft 59 to rotate, and the rotating shaft 59 drives the carrying plate 551 to rotate, and the carrying plate 551 drives the annular workpiece 552 to rotate. During the rotation of the annular workpiece 552, it contacts the bottom of the curling roller 556, so that the annular workpiece 552 is curled during the rotation. At the same time, the rotating shaft 59 drives the belt 52 to rotate, and the belt 52 drives the rotating screw 3 to rotate, which is limited by the limit rod 4. The threaded plate 53 is rotated to move vertically along the outer wall of the limiting rod 4, and the threaded plate 53 drives the conical part 54 to move downward. During the descending process, the conical part 54 will contact one side of the outer wall of the arc shell 564, squeeze the arc shell 564, and make multiple arc shells 564 move away from each other. The arc shell 564 drives the bent rod 565 to move, and the bent rod 565 drives the extrusion shell 566 to move, and the multiple extrusion shells 566 move away from each other, so that the inner wall of the annular workpiece 552 can be supported and moved, thereby improving the stability of the annular workpiece 552 driven by the supporting plate 551 to rotate, and improving the curling effect of the annular workpiece 552.

[0051] When the extrusion shell 566 contacts the annular workpiece 552, the extrusion shell 566 is prevented from over-extruding the annular workpiece 552 and causing damage to the annular workpiece 552. The extrusion shell 566 drives the bending rod 565 to move inside the arc shell 564, thereby improving the protection effect of the curling of the annular workpiece 552. The bending rod 565 drives the rotating plate 571 to move inside the arc shell 564. The rotating plate 571 is limited by the vertical groove 572, and the lifting block 573 moves along the inner wall of the vertical groove 572. It descends vertically, and the lifting block 573 drives the connecting rod 574 to descend, the connecting rod 574 drives the concave rod 576 to descend, the concave rod 576 drives the connecting frame 577 to descend, and the connecting frame 577 drives the lower pressure plate 578 to descend. During the descending process, the lower pressure plate 578 will contact the top of the curling roller 556, so that the curling roller 556 is further fitted with the top of the annular workpiece 552, thereby improving the curling effect of the curling roller 556 on the annular workpiece 552.

[0052] When the lifting block 573 moves downward, the lifting block 573 drives the vertical rod 581 to move downward, and the vertical rod 581 drives the piston plate 582 to move downward. The piston plate 582 moves downward on the inner wall of the arc shell 564, so that the airflow inside the arc shell 564 enters the elastic tube 584, and the airflow enters the extrusion shell 566 through the elastic tube 584. After the airflow enters the extrusion shell 566, the lifting plate 585 inside the extrusion shell 566 moves upward, and the lifting plate 585 drives the round rod 586 to move upward, and the round rod 586 drives the arc shell 564 to move upward. The semicircular rod 587 moves upward, and during the upward movement, the arc-shaped semicircular rod 587 will fit together with the edge of the annular workpiece 552, thereby preventing the angle after curling from being inconsistent with the preset standard, and making the angle after curling the same as the arc angle of the arc-shaped semicircular rod 587, thereby improving the curling quality of the annular workpiece 552. At the same time, when the arc-shaped semicircular rod 587 drives the annular workpiece 552 to move upward, the annular workpiece 552 can be further fitted with the bottom of the outer wall of the curling roller 556, thereby further improving the stability of the curling of the annular workpiece 552.
