Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] The anti-damage component 4 includes a liquid storage tank 41, the lower surface of which is fixedly connected to the inner wall of the bottom surface of the machine platform 1, and a piston cylinder 42 is fixedly installed on the upper surface of the liquid storage tank 41. A liquid inlet pipe 43 and a liquid outlet pipe 46 are connected and installed on the outer surface of the piston cylinder 42. A one-way valve is fixedly installed on the inner walls of the liquid inlet pipe 43 and the liquid outlet pipe 46. One end of the liquid inlet pipe 43 extends to the interior of the liquid storage tank 41, and one end of the liquid outlet pipe 46 extends to the interior of the fixed platform 2 and is connected and installed with a fixed pipe 47. A drip head 48 is connected and installed on the side wall of the fixed pipe 47, and one end of the drip head 48 extends to the fixed platform 2. On the outside, a piston plate 44 is slidably mounted on the inner wall of the piston cylinder 42, and a connecting rod 45 is rotatably mounted on the upper surface of the piston plate 44 through a mounting clamp, and one end of the connecting rod 45 extends to the outside of the upper surface of the piston cylinder 42, and a rotating rod 49 is rotatably mounted on the inner wall of the machine table 1, and a rotating disk 410 is fixedly mounted on one end of the rotating rod 49, and the side wall of the rotating disk 410 is rotatably connected to the connecting rod 45 through a rotating shaft, and a transmission gear 411 is fixedly mounted on the outer surface of the rotating rod 49, and a fixed rack 6 is fixedly mounted on the lower surface of the moving block 7, and the fixed rack 6 is meshed and connected with the transmission gear 411.

[0029] The specific implementation method is as follows: when the moving block 7 descends, it will drive the fixed rack 6 to descend synchronously. At this time, under the action of the transmission gear 411, the rotating rod 49 will be driven to rotate, and the rotating rod 49 will drive the rotating disk 410 to rotate, so that the connecting rod 45 drives the piston plate 44 to move up and down in the piston cylinder 42. When the piston plate 44 moves up, the lubricating liquid is sucked into the piston cylinder 42 through the liquid inlet pipe 43. When the piston plate 44 descends, the lubricating liquid in the piston cylinder 42 is squeezed into the fixed tube 47 through the liquid outlet pipe 46, and then drips onto the rotating cover 51 and the outer surface of the workpiece through the drip head 48.

[0030] The positioning assembly 5 includes a rotating cover 51, and the rotating cover 51 is rotatably installed on the side walls of the movable block 7 and the fixed platform 2 through a rotating shaft. A fixed block 52 is fixedly installed on the inner wall of the rotating cover 51, and a connecting spring 53 is fixedly installed on the side wall of the fixed block 52. A positioning cover 54 is fixedly installed on one end of the connecting spring 53. The outer surface of the positioning cover 54 is slidably connected to the inner wall of the rotating cover 51, and a positioning plate 55 is fixedly installed on the side wall of the positioning cover 54.

[0031] The specific implementation method is as follows: the positioning plate 55 is pulled outward, thereby driving the positioning cover 54 to move from the inside of the rotating cover 51, and then the workpiece is placed on the upper surface of the rotating cover 51. Under the action of the connecting spring 53, the positioning cover 54 will be pulled into the rotating cover 51. At this time, the positioning cover 54 will drive the positioning plate 55 to limit the workpiece, and the hydraulic rod 3 will drive the moving block 7 to move downward. At this time, the rotating cover 51 on the moving block 7 will drop synchronously, thereby squeezing the workpiece. As the moving block 7 drives the rotating cover 51 to continue to drop, it stops moving after the workpiece is bent to an appropriate angle.

[0032] Working principle: Pull the positioning plate 55 outward to drive the positioning cover 54 to move from the inside of the rotating cover 51, and then put the workpiece on the upper surface of the rotating cover 51. Under the action of the connecting spring 53, the positioning cover 54 will be pulled into the rotating cover 51. At this time, the positioning cover 54 will drive the positioning plate 55 to limit the workpiece, and the hydraulic rod 3 will drive the moving block 7 to move downward. At this time, the rotating cover 51 on the moving block 7 will drop synchronously, thereby squeezing the workpiece. As the moving block 7 drives the rotating cover 51 to continue to drop, it stops moving after the workpiece is bent to an appropriate angle. When the moving block 7 descends, it will drive the fixed rack 6 to descend synchronously. At this time, under the action of the transmission gear 411, the rotating rod 49 will be driven to rotate, and the rotating rod 49 will drive the rotating disk 410 to rotate, so that the connecting rod 45 drives the piston plate 44 to move up and down in the piston cylinder 42. When the piston plate 44 moves up, the lubricating liquid is sucked into the piston cylinder 42 through the liquid inlet pipe 43. When the piston plate 44 descends, the lubricating liquid in the piston cylinder 42 is squeezed into the fixed pipe 47 through the liquid outlet pipe 46, and then drips onto the rotating cover 51 and the outer surface of the workpiece through the drip head 48.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
