[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0021] The utility model provides a technical solution: Figure 1 - Figure 4 As shown, in this embodiment, a double-station servo blanking mechanism includes a workbench 1, a blanking mechanism 2 is fixedly installed on one side of the upper end of the workbench 1, a lower mold 5 is fixedly installed on one side of the upper end of the workbench 1, an upper mold 4 is arranged above the lower mold 5, pull rods 12 are fixedly installed on both sides of the upper mold 4, sliding columns 10 are fixedly connected on both sides of the lower mold 5, an ejector plate 7 is arranged below the lower mold 5, a plurality of ejector pins 8 are fixedly connected to the upper end of the ejector plate 7, the outer surfaces of the plurality of ejector pins 8 are slidably connected to the inner wall of the lower mold 5, and a rotating rack 9 is rotatably connected to both sides of the ejector plate 7, and one side of the two rotating racks 9 is penetrated by a special-shaped Groove 11, the inner walls of the two special-shaped grooves 11 are slidably connected to the outer walls of the two sliding columns 10 respectively, and one side of the two rotating frames 9 is respectively clamped with one side of the two pull rods 12. When the servo motor 22 is turned on to pull the upper mold 4 upward, the pull rod 12 will move the rotating frame 9 upward, and the ejector pin 8 on the ejection plate 7 will eject the workpiece in the lower mold 5. The sliding column 10 slides in the special-shaped groove 11. When it slides halfway, the rotating frame 9 rotates on the ejection plate 7 to separate the rotating frame 9 from the pull rod 12. When the workpiece is taken out, the cooperation of the pull rod 12 and the rotating frame 9 can eject the workpiece in the lower mold 5 when the mold is opened, thereby improving the production efficiency of the blanking mechanism.

[0022] like Figure 3 and Figure 4 As shown, the lower end of the workbench 1 is fixedly connected to the mounting frame 6, and the middle part of the mounting frame 6 is fixedly connected to the return spring 23, one end of the return spring 23 is fixedly connected to the lower end of the ejection plate 7, and multiple guide rods 24 are fixedly connected to the inner sides of the mounting frame 6, and one side of the multiple guide rods 24 is slidably connected to the outer wall of the ejection plate 7. The return spring 23 can prevent the pull rod 12 from releasing the restriction of the rotating frame 9. The gravity of the ejection plate 7 slides the ejector pin 8 to the initial position, resulting in the pull rod 12 and the rotating frame 9 being unable to be engaged.

[0023] like Figure 3 As shown, a servo motor 22 is fixedly installed on one side of the punching mechanism 2, and the output end of the servo motor 22 is transmission-connected to the rotating disk 17, and a lifting rod 18 is rotatably connected to the edge of one side of the rotating disk 17, and one end of the lifting rod 18 is rotatably connected to the sliding frame 19, and one end of the sliding frame 19 is fixedly connected to the upper end of the upper mold 4. By turning on the servo motor 22, the rotating disk 17 is rotated, and the sliding frame 19 is reciprocated on the punching mechanism 2, thereby punching the workpiece.

The slide 21 can limit the sliding direction of the sliding frame 19 to prevent long-term use from causing misalignment between the upper mold 4 and the lower mold 5.

[0025] like Figure 3 and Figure 4 As shown, reinforcing ribs 20 are fixedly connected to both sides of the sliding frame 19 , and one side of the two reinforcing ribs 20 is fixedly connected to the upper end of the upper mold 4 . The reinforcing ribs 20 can strengthen the connection between the sliding frame 19 and the upper mold 4 .

[0026] like Figure 1 and Figure 2 As shown, a punching mechanism 2 3 is fixedly installed on the other side of the upper end of the workbench 1. By installing the punching mechanism 2 3 on the workbench 1, the equipment can form a double workstation. When the punching mechanism 1 2 is punching, the staff can load materials on the punching mechanism 2 3, thereby improving the production efficiency of the equipment. The structures of the punching mechanism 1 2 and the punching mechanism 2 3 are the same.

[0027] like Figure 1 and Figure 2 As shown, a noise-proof cover 13 is fixedly connected to the upper edge of the workbench 1, and cooling fans 16 are fixedly installed on both sides of the noise-proof cover 13. A mounting frame 14 is provided on one side of the two cooling fans 16, and one side of the two mounting frames 14 is fixedly connected to both sides of the noise-proof cover 13. The inner walls of the two mounting frames 14 are slidably connected with a filter screen 15. By turning on the cooling fan 16, the flow speed of the gas between the upper mold 4 and the lower mold 5 is accelerated, thereby cooling the upper mold 4 and the lower mold 5, preventing the upper mold 4 and the lower mold 5 from being used for a long time, causing serious wear of the upper mold 4 and the lower mold 5, and improving the service life of the mold.

[0028] The utility model provides a double-station servo blanking mechanism, the specific working principle of which is as follows:

[0029] When the workpiece is punched, first place the workpiece on the lower mold 5 on the punching mechanism 2, turn on the servo motor 22, move the upper mold 4 downward, punch the workpiece, and close the upper mold 4 and the lower mold 5. After the punching is completed, the sliding frame 19 pulls the upper mold 4 upward, and the pull rod 12 will move the rotating frame 9 upward. The ejector pin 8 on the ejector plate 7 will eject the workpiece in the lower mold 5, and the sliding column 10 slides in the special-shaped groove 11. When sliding halfway, the rotating frame 9 rotates on the ejector plate 7 to separate the rotating frame 9 from the pull rod 12 and take the workpiece out of the lower mold 5. While taking out the workpiece, turn on the cooling fan 16 to speed up the flow of gas between the upper mold 4 and the lower mold 5, thereby cooling the upper mold 4 and the lower mold 5. When the punching mechanism 2 is punching, the staff can place the workpiece in the lower mold 5 on the punching mechanism 2 3 for punching.
