[0032] In this embodiment: the rolling mechanism 1 includes a lower pressure roller 12, which is rotatably connected to the top of the frame 2, and a driving component is fixedly arranged at the input end of the lower pressure roller 12 to drive it to rotate; an upper pressure roller 11 is arranged on the upper side of the lower pressure roller 12, and an adjusting frame 13 for adjusting its height is arranged on the front and rear ends of the upper pressure roller 11; a sliding seat supporting the upper pressure roller 11 is slidably connected inside the adjusting frame 13, and a threaded rod is rotatably connected to the top of the sliding seat, and the upper side of the threaded rod is connected to the upper end of the adjusting frame 13 by threads; a locking nut for fixing the threaded rod is arranged on the top of the adjusting frame 13, and the locking nut is loosened and the threaded rod is rotated to drive the sliding seat to slide up and down along the inside of the adjusting frame 13, thereby driving the upper pressure roller 11 to approach or move away from the lower pressure roller 12 through the sliding seat, and then adjusting the distance between the upper pressure roller 11 and the lower pressure roller 12 according to the thickness of the workpiece.

[0033] In this embodiment: the shearing mechanism 3 includes a shearing frame 31, a shearing base 34 is fixed at the bottom side of the shearing frame 31, a shearing tool holder 33 is slidably connected to the upper side of the shearing base 34, the upper side of the shearing tool holder 33 is fixed to the telescopic part of the hydraulic cylinder 32, the fixed part of the hydraulic cylinder 32 is fixedly connected to the top of the shearing frame 31, and the telescopic part of the hydraulic cylinder 32 is used to push the shearing tool holder 33 to move downward along the shearing frame 31 to cut the workpiece extending from the shearing base 34.

[0034] In this embodiment: the export mechanism 6 includes a support frame 61, which is arranged at the delivery end of the shearing mechanism 3. A flip plate 62 is hinged on the front side of the support frame 61, and a hydraulic cylinder 32 is hinged on the lower side of the flip plate 62. The fixed part of the hydraulic cylinder 32 is hinged on the lower end of the support frame 61. A export box 64 is provided on the front side of the flip plate 62. A lifting hydraulic rod 65 for driving the export box 64 to lift and fall is fixed on one side of the export box 64. The front and rear sides of the lower end of the export box 64 are rotatably connected with a buffer flap 66 for reducing the impact force when the workpiece falls. The support frame 61 extends into the interior of the collection box 5. A bracket for supporting the fixed part of the flip cylinder 63 is fixed on the lower side of the middle position of the support frame 61. A swivel seat for connecting with the rotating part of the flip cylinder 63 is fixed on the lower side of the flip plate 62. Flip openings are provided on both sides of the lower end of 64, and a fixed shaft for supporting the buffer flap 66 is fixed on the inner side of the flip opening. The flip plate 62 on the support frame 61 is used to support the workpiece during shearing. After the workpiece is sheared, the workpiece falls on the flip plate 62, and then the telescopic part of the flip cylinder 63 retracts and drives the flip plate 62 to flip downward. Then, after flipping, the flip plate 62 will slide the workpiece into the export box 64, and then the workpiece will fall along the export box 64 onto the two buffer flaps 66. The workpiece is supported by the two buffer flaps 66 to slow down its falling speed. At the same time, with the action of gravity of the workpiece, the two buffer flaps 66 begin to flip and allow the workpiece to continue to fall along the inner wall of the export box 64, and then the workpiece falls from the lower end of the export box 64 to the inside of the collection box 5.

[0035] In this embodiment: the protection mechanism 7 includes an arc frame 71, which is fixed on the side of the export box 64 close to the support frame 61, and a rotating roller 73 is provided on the inner side of the arc frame 71. A metal sheet 74 is wound on the outer side of the rotating roller 73, and a protection motor 72 is fixedly provided on the input end of the rotating roller 73. A slot for receiving the sheared workpiece is provided on the side of the export box 64 close to the flip plate 62, and slide grooves are provided at both ends of the slot of the export box 64 to facilitate the sliding of the metal sheet 74. The protection motor 72 is rotated to drive the rotating roller 73 to rotate in the opposite direction, so that one end of the metal sheet 74 is extended into the slide groove of the export box 64 along the inner wall of the arc frame 71, and then the metal sheet 74 extended into the slide groove is adjusted to match the slot size of the flip plate 62 according to the height of the export box 64.

[0036] Working principle: When in use, firstly, the threaded rod is rotated in sequence according to the thickness of the rolled sheet, and the upper pressing roller 11 is driven to approach or move away from the lower pressing roller 12 through the sliding seat, and then the distance between the upper pressing roller 11 and the lower pressing roller 12 is adjusted according to the thickness of the workpiece, and then the threaded rod is locked by the locking nut, and then the lower pressing roller 12 is driven to rotate by the driving assembly, and then the rolled sheet is rolled and formed by the rolling rotation of multiple groups of lower pressing rollers 12 and upper pressing rollers 11;

[0037] After the rolled sheet is formed, it is fed into the inner side of the shearing base 34 by the rotation input of multiple sets of conveying rollers 4, and then the rolled sheet is sent out through the forming hole of the shearing base 34. After the rolled sheet is sent out of the shearing base 34 by a suitable distance, the telescopic part of the hydraulic cylinder 32 pushes the shearing tool holder 33 into the inside of the shearing base 34, thereby shearing the formed sheet extending out of the shearing base 34, and then forming a single workpiece and falling on the flip plate 62;

[0038] In addition, when the workpiece is sheared, the retractable part of the reversing cylinder 63 pushes the reversing plate 62 to keep it horizontal, and then supports the workpiece to be cut. As the workpiece is cut, the retractable part of the reversing cylinder 63 drives the reversing plate 62 to flip downward, and then the flipped reversing plate 62 sends the workpiece into the slot of the export box 64, and the workpiece falls downward along the inner wall of the export box 64. When the workpiece falls to the two buffer flaps 66, the buffer flaps 66 are used to support the falling workpiece, thereby temporarily stopping the workpiece from falling. Due to the effect of the gravity of the workpiece, the two buffer flaps 66 are flipped downward at the same time, and then the workpiece continues to fall along the inner wall of the export box 64, and then the workpiece falls into the collection box 5 along the lower end of the export box 64, and then in this process, the impact force of the entire workpiece falling is reduced. Figure 5 As shown, the buffer flap 66 is reset under the action of gravity at one end of the outgoing box 64. After a certain amount of workpieces are fed into the collecting box 5, the telescopic part of the lifting hydraulic rod 65 drives the outgoing box 64 to move upward, so that the workpieces can be stacked upward in the collecting box 5.

[0039] During the entire process of the export box 64 being lifted upward, the protective motor 72 drives the rotating roller 73 to rotate, thereby winding the metal sheet 74 on the outside of the rotating roller 73, and the metal sheet 74 will slide out into the slide groove of the export box 64, and then one end of the metal sheet 74 located in the slide groove of the export box 64 will move downward, and then the size of the slot will be expanded, so that the workpiece on the flip plate 62 can slide into the inside of the export box 64.

[0040] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
