After being squeezed by the upper die 14, the workpiece will squeeze the top block 18 downward to compress the first spring 17. After the workpiece completes flanging, the upper die 14 is driven upward by the oil cylinder 13. At this time, the top block 18 will push the workpiece upward under the elastic force of the first spring 17, so that the workpiece trapped in the lower die 12 is ejected from the lower die 12. Through the above structure, the workpiece trapped in the lower die 12 can be automatically taken out after the workpiece completes flanging, thereby increasing the flanging speed.

[0023] like Figures 1 to 4As shown, the side wall of the processing table 1 is fixedly connected with a liquid storage tank 2; the top of the liquid storage tank 2 is fixedly connected with an air bag 21; the middle of the air bag 21 is fixedly connected with a liquid spraying pipe 22; the liquid spraying pipe 22 is arranged toward the top of the lower mold 12; the bottom of the air bag 21 is fixedly connected with a liquid inlet pipe 23; the liquid inlet pipe 23 extends to the inside of the liquid storage tank 2; the middle of the liquid spraying pipe 22 is fixedly connected with a first one-way valve 24; the middle of the liquid inlet pipe 23 is fixedly connected with a second one-way valve 25; the inside of the air bag 21 is fixedly connected with a second spring 26; the side wall of the upper mold 14 is fixedly connected with a pressing plate 27; when working, Lubricating liquid is injected into the box 2, and then the air bag 21 is pressed and released once so that the lubricating liquid inside the liquid storage box 2 is drawn into the air bag 21.

Through the above structure, the lubricating liquid can be automatically sprayed on the surface of the workpiece, reducing the friction damage to the workpiece, and making it easier for the workpiece to be ejected from the inside of the lower mold 12 by the ejector block 18.

[0024] like Figures 1 to 3 As shown, the bottom of the first groove 15 is rotatably connected with a screw rod 3; the bottom end of the screw rod 3 is fixedly connected with a first gear 31; the middle part of the processing table 1 is rotatably connected with a rotating rod 32; the end of the rotating rod 32 extends to the inside of the first groove 15 and is fixedly connected with a second gear 33; the second gear 33 is meshed with the first gear 31; the middle part of the screw rod 3 is threadedly connected with a load ring 34; the load ring 34 is slidably connected to the middle part of the first groove 15; the first spring 17 is located above the load ring 34; during operation, when the material or specification of the workpiece changes, the elastic force of the first spring 17 may be insufficient In order to eject the workpiece from the inside of the lower mold 12, the rotating rod 32 can be rotated to drive the screw 3 to rotate through the cooperation between the second gear 33 and the first gear 31, thereby driving the supporting ring 34 to move along the middle part of the screw 3. By moving the supporting ring 34 upward, the first spring 17 can be compressed, thereby increasing the elastic force of the first spring 17. Similarly, the supporting ring 34 can be moved downward to reduce the elastic force of the first spring 17, thereby reducing the obstruction encountered when the cylinder 13 is pressed downward. Through the above structure, the lifting force of the ejector block 18 can be adjusted to reduce the occurrence of the workpiece being stuck in the lower mold 12.

[0025] like Figures 1 to 3As shown, a plurality of first through holes 4 are provided in the middle of the top block 18; a guide plate 41 is fixedly connected to the bottom of the top block 18; during operation, part of the lubricating fluid will flow to the top of the top block 18 through the second groove 16, then flow down through the first through holes 4, and then fall on the top of the screw 3 along the guide plate 41, thereby lubricating the middle of the screw 3, making the rotation between the screw 3 and the load-bearing ring 34 smoother, and reducing the occurrence of rust and jamming between the screw 3 and the load-bearing ring 34.

[0026] like Figures 1 to 3 As shown, a plurality of second through holes 5 are provided in the middle of the first gear 31; the plurality of second through holes 5 are arranged in a circular array; during operation, the lubricating fluid will flow down along the middle of the screw 3 to the top of the first gear 31, and then penetrate into between the first gear 31 and the processing table 1 through the second through holes 5, thereby reducing the friction between the first gear 31 and the processing table 1, making the rotation of the first gear 31 more labor-saving, and reducing the occurrence of rust and jamming between the first gear 31 and the processing table 1.

[0027] like Figure 1 to Figure 2 As shown, a plurality of third through holes 6 are provided in the middle of the processing table 1; a liquid collecting box 61 is slidably connected to the middle of the processing table 1; during operation, excess lubricating liquid will fall into the interior of the liquid collecting box 61 through the third through holes 6, completing the collection of excess lubricating liquid, facilitating the reuse of the lubricating liquid and reducing the waste of resources.

[0028] like Figure 2 As shown, the side wall of the liquid collecting box 61 is fixedly connected to the first magnet 7; the side wall of the processing table 1 is fixedly connected to the second magnet 71; the second magnet 71 and the first magnet 7 are arranged to attract each other; through the above structure, when the device is running, the deviation of the third through hole 6 due to vibration can be reduced, thereby reducing the outflow of lubricating liquid.

[0029] During operation, the workpiece to be flanging is placed above the lower die 12, and then the oil cylinder 13 is started to drive the upper die 14 to descend to extrude and flanging the workpiece. After being squeezed by the upper die 14, the workpiece will press the top block 18 downward to compress the first spring 17. After the workpiece completes the flanging, the upper die 14 is driven upward by the oil cylinder 13. At this time, the top block 18 will push the workpiece upward under the elastic force of the first spring 17, so that the workpiece trapped in the lower die 12 is ejected from the lower die 12, and the workpiece is stored in the liquid. The lubricating liquid is injected into the tank 2, and then the airbag 21 is pressed and released once so that the lubricating liquid in the tank 2 is pumped into the airbag 21. When the upper mold 14 moves downward, the pressing plate 27 squeezes the airbag 21, so that the lubricating liquid in the airbag 21 is sprayed through the liquid inlet pipe 23 to the surface of the workpiece above the lower mold 12 and above the lower mold 12, thereby reducing the friction of the workpiece when the workpiece is extruded and flanging. When the material or specification of the workpiece changes, the elastic force of the first spring 17 may not be enough to lift the workpiece from the lower mold. The inner part of the tool 12 is ejected. At this time, the rotating rod 32 can be rotated to drive the screw rod 3 to rotate through the cooperation between the second gear 33 and the first gear 31, thereby driving the bearing ring 34 to move along the middle of the screw rod 3. By moving the bearing ring 34 upward, the first spring 17 can be compressed, thereby increasing the elastic force of the first spring 17. Similarly, the bearing ring 34 can be moved downward to reduce the elastic force of the first spring 17, thereby reducing the obstruction when the oil cylinder 13 is pressed downward. When working, part of the lubricating fluid will flow to the top through the second groove 16 The lubricating liquid will flow down along the middle of the screw 3 to the top of the first gear 31, and then penetrate into between the first gear 31 and the processing table 1 through the second through hole 5, thereby reducing the friction between the first gear 31 and the processing table 1. The excess lubricating liquid will fall into the liquid collecting box 61 through the third through hole 6, completing the collection of the excess lubricating liquid and facilitating the reuse of the lubricating liquid.
