Compared with the prior art, the sheet to be processed is placed on the top of the lower mold, the hydraulic cylinder pushes the movable plate to move downward, the motor drives the rolling mold to rotate, the floating pressure plate presses the sheet, and the lower mold is ejected upward by the ejection hydraulic cylinder, thereby achieving mutual extrusion between the rolling mold and the lower mold.

[0026] like Figure 2 , Figure 3 As shown, the limiting mechanism is clamped in the limiting hole 18, and the limiting hole 18 is provided in the cross plate 3. When the cross plate 3 moves to the position of the limiting mechanism, the limiting mechanism is clamped in the limiting hole 18, so that the cross plate 3 cannot continue to move downward. A through hole 19 is provided in the connecting rod 8, and a clamping mechanism is clamped in the through hole 19. The clamping mechanism is arranged in the cross plate 3, and the end of the clamping mechanism away from the connecting rod 8 extends into the limiting hole 18. When the limiting mechanism is clamped in the limiting hole 18, the limiting mechanism will push the clamping mechanism to move, so that the clamping mechanism The clamping end of the mechanism is disengaged from the through hole 19, and the connecting rod 8 is in an active state. The upper ends of the two connecting rods 8 are fixedly connected to the support plate 7, and the upper ends of the two support columns 2 are fixedly connected to the top plate 5. The upper end of the top plate 5 is fixedly connected to the first hydraulic cylinder 6. The first hydraulic cylinder 6 can be selected with corresponding size and model in actual use. The output end of the first hydraulic cylinder 6 passes through the top plate 5 and is fixedly connected to the support plate 7. A pressing mechanism is provided at the upper end of the bottom plate 1, which drives the material plate to contact the arc rolling die 10 through the pressing mechanism.

[0027] Embodiment 2:

[0028] On the basis of Example 1, in order to make the arc rolling die 10 no longer move downward after moving to a specific position, as shown in FIG. Figure 4As shown, the transmission mechanism includes an inner gear ring 16, which is slidably connected in a T-shaped ring groove 27, which is provided in the upper end of the bottom plate 1, and the lower end of the support column 2 is slidably connected in the T-shaped ring groove 27 and fixedly connected to the upper end of the inner gear ring 16. A transmission gear 17 is meshed on the inner side of the inner gear ring 16, and the transmission gear 17 is movably connected in the bottom plate 1. A transmission motor 28 is fixedly connected to the lower end of the bottom plate 1, and the output end of the transmission motor 28 extends into the bottom plate 1 and is fixedly connected to the transmission gear 17. When the transmission motor 28 is turned on, the transmission gear 17 is driven to rotate, and the rotation of the transmission gear 17 drives the inner gear ring 16 to rotate, and the rotation of the inner gear ring 16 drives the two support columns 2 connected to its upper end to rotate, and at this time, the cross plate 3 will rotate along and drive the arc rolling die 10 connected to its lower end to rotate;

[0029] like Figure 2 As shown, the limiting mechanism includes a T-shaped limiting block 22, the upper end of the T-shaped limiting block 22 is arranged in an arc shape, one end of the T-shaped limiting block 22 is slidably connected to the limiting cavity 24, the limiting cavity 24 is arranged in the support column 2, a first spring 25 is fixedly connected in the limiting cavity 24, the other end of the first spring 25 is fixedly connected to the T-shaped limiting block 22, an electromagnet 23 is arranged inside the first spring 25, and the electromagnet 23 is fixedly connected to the limiting cavity 24. When the connecting rod 8 moves, the cross plate 3 will also move along with it. When the cross plate 3 moves along the support column 2 to the position of the T-shaped limiting block 22, at this time, as the cross plate 3 continues to move downward, the T-shaped limiting block 22 will be squeezed to move into the limiting cavity 24, and when the limiting hole 18 opened in the cross plate 3 moves to the position of the T-shaped limiting block 22, at this time, under the elastic force of the first spring 25, the T-shaped limiting block 22 will be snapped into the limiting hole 18;

[0030] like Figure 3 As shown, the clamping mechanism includes a curved clamping rod 4, which is slidably connected to the sliding cavity 21, and the sliding cavity 21 is opened in the cross plate 3. One end of the curved clamping rod 4 is clamped in the through hole 19, and the other end extends into the limiting hole 18. A second spring 20 is fixedly connected in the sliding cavity 21, and the other end of the second spring 20 is fixedly connected to the curved clamping rod 4. When the limiting hole 18 opened in the cross plate 3 moves to the position of the T-shaped limiting block 22, at this time, under the elastic force of the first spring 25, the T-shaped limiting block 22 will be clamped into the limiting hole 18, and the curved clamping rod 4 located in the limiting hole 18 will be pushed by the T-shaped limiting block 22 to move. At this time, the clamping end of the curved clamping rod 4 is separated from the through hole 19, and when the connecting rod 8 moves downward, it will not drive the cross plate 3 to move downward. At the same time, it is clamped into the limiting hole 18 by the T-shaped limiting block 22, so that the cross plate 3 is fixed and limited;

[0031] The pressing mechanism includes a lower template 13, which is a conical protrusion block, and its upper end is arranged in an arc shape. The upper end of the lower template 13 is arranged in an arc shape. The lower template 13 is arranged in a clearance groove 26, and the clearance groove 26 is opened in the upper end of the bottom plate 1. A second hydraulic cylinder 15 is fixedly installed at the lower end of the bottom plate 1. The output end of the second hydraulic cylinder 15 extends into the clearance groove 26 and is fixedly connected to the lower template 13. The second hydraulic cylinder 15 is turned on to drive the lower template 13 to move upward. When the lower template 13 moves upward, the material plate is squeezed so that the material plate contacts the arc rolling die 10. Under the cooperation of the rotating arc rolling die 10 and the lower template 13, the material plate will be frictionally rolled into an arc. The upper end of the bottom plate 1 is movably connected with four pressing plates 11 through a screw 12, and a cutter 14 is fixedly connected to the side of the arc pressure rod 9 away from the arc rolling die 10.

[0032] Working principle: when in use, rotate the screw 12 upward to remove the pressing plate 11, and place the material plate on the upper side of the lower template 13, between the four pressing plates 11. After placement, press the four pressing plates 11 on top of the material plate, and tighten the pressing plates 11 through the screw 12, so that the material plate is clamped on top of the bottom plate 1, open the first hydraulic cylinder 6 to drive the support plate 7 connected to its output end to move downward, and the movement of the support plate 7 drives the two connecting rods 8 to move synchronously. Since the clamping end of the curved clamping rod 4 is clamped in the through hole 19, when the connecting rod 8 moves, the cross plate 3 will also move with it. When the cross plate 3 moves along the support column 2 to the position of the T-shaped limit block 22, at this time, as the cross plate 3 continues to move downward, the T-shaped limit block 22 will be squeezed to move into the limit cavity 24;

[0033] When the limiting hole 18 opened in the cross plate 3 moves to the position of the T-shaped limiting block 22, under the elastic force of the first spring 25, the T-shaped limiting block 22 will be clamped into the limiting hole 18, and the curved clamping rod 4 in the limiting hole 18 will be pushed by the T-shaped limiting block 22 to move. At this time, the clamping end of the curved clamping rod 4 is separated from the through hole 19, and the connecting rod 8 will not drive the cross plate 3 to move downward when moving downward. At the same time, the cross plate 3 is clamped into the limiting hole 18 by the T-shaped limiting block 22, so that the cross plate 3 is fixed and limited;

[0034] The transmission motor 28 is turned on to drive the transmission gear 17 to rotate. The rotation of the transmission gear 17 drives the inner gear ring 16 to rotate. The rotation of the inner gear ring 16 drives the two support columns 2 connected to its upper end to rotate. At this time, the cross plate 3 will follow the rotation and drive the arc rolling die 10 connected to its lower end to rotate. The second hydraulic cylinder 15 is turned on to drive the lower template 13 to move upward. When the lower template 13 moves upward, it squeezes the material sheet so that the material sheet contacts the arc rolling die 10. Under the cooperation of the rotating arc rolling die 10 and the lower template 13, the material sheet will be frictionally rolled into an arc. The first hydraulic cylinder 6 is controlled to drive the support The plate 7 moves downward again, and at this time, the two connecting rods 8 drive the arc-shaped edge-holding rod 9 to move downward. When the cutter 14 connected to one side of the arc-shaped edge-holding rod 9 contacts the material sheet rolled into an arc shape, the cutter 14 driven by the horizontal plate 3 will cut the material sheet, so that the material sheet rolled into an arc shape is clamped between the arc-shaped rolling die 10 and the lower die plate 13. At the same time, after the cutter 14 cuts the material sheet, the burrs on the outer side of the processed sheet can be reduced. At this time, as the arc-shaped edge-holding rod 9 continues to move downward in a rotating state, the outer side of the cut material sheet will be bent, and the processing is completed at this time.

[0035] After turning off the transmission motor 28, turn on the electromagnet 23. After the electromagnet 23 is turned on, it adsorbs the T-shaped limit block 22, so that the T-shaped limit block 22 is separated from the limit hole 18. At this time, the first hydraulic cylinder 6 is controlled to drive the support plate 7 to move downward. When the through hole 19 moves to the position of the curved clamping rod 4, under the elastic force of the second spring 20, the clamping end of the curved clamping rod 4 will be clamped into the through hole 19. At this time, the connecting rod 8 will drive the cross plate 3 to move again when it moves. When the arc rolling die 10 returns to its original position, the processed water tank end cover can be removed.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
