[0020] Please see Figure 1-4 This utility model provides an embodiment of an edge-expanding processing device for annular casing forgings, comprising a base body 1, a supporting side plate 2, and a PLC controller 3. An equipment slot 10 is provided through the upper middle part of the supporting side plate 2. A lifting frame 11 is slidably connected inside the equipment slot 10. The forging can be extruded by the up-and-down sliding of the lifting frame 11. A first rotating shaft 12 is rotatably connected to the bottom inner side of the lifting frame 11. A first servo motor 19 is fixedly installed on the side of the lifting frame 11 away from the first rotating shaft 12. A second rotating shaft 18 is rotatably connected to the bottom of the equipment slot 10. A second servo motor 20 is fixedly installed on the side of the supporting side plate 2 near the first servo motor 19.
[0021] A second electro-hydraulic rod 13 is fixedly installed at the top center of the supporting side plate 2. The telescopic end of the second electro-hydraulic rod 13 is fixedly installed at the top of the lifting frame 11. Two limiting grooves 14 are symmetrically opened on the outer side of the first rotating shaft 12. An edge-expanding pressure roller 16 is nested on the outer side of the first rotating shaft 12. The edge-expanding pressure roller 16 can be set with various specifications. Different specifications of edge-expanding pressure roller 16 are used for edge-expanding operations according to different needs. Two edge-expanding pressure rollers are symmetrically fixedly connected on the inner side of the edge-expanding pressure roller 16. The limiting block 17 is slidably inserted into the inner side of the limiting groove 14. The limiting block 17 is inserted into the inner side of the limiting groove 14 to limit and fix the expanding edge pressure roller 16. The bottom end of the lifting frame 11 near the expanding edge pressure roller 16 is fixedly installed with an atomizing nozzle 15. The nozzle end of the atomizing nozzle 15 is tilted upward, and the atomizing nozzle 15 is located in the middle of the outer side of the expanding edge pressure roller 16 in the horizontal direction, so that the atomizing nozzle 15 can spray water evenly on the outer side of the expanding edge pressure roller 16.
[0022] The base body 1 has a groove 5 at its top. A first electro-hydraulic rod 6 is fixedly installed in the middle of one side of the groove 5. A support rod 7 is fixedly installed at the telescopic end of the first electro-hydraulic rod 6. The second rotating shaft 18 is supported by the top of the support rod 7 to prevent excessive pressure from damaging the equipment. A water tank 4 is fixedly installed on one side of the top of the base body 1. A water pump 9 is fixedly installed on the top of the water tank 4. The input end of the water pump 9 is set inside the water tank 4 through a water pipe. The output end of the water pump 9 is connected to the input end of the atomizing nozzle 15 through a water pipe. The water pump 9 delivers water from the water tank 4 to the atomizing nozzle 15 and sprays it out to cool the outside of the expanding pressure roller 16. The support side plate 2 is fixedly installed on the side of the groove 5 away from the first electro-hydraulic rod 6. The water tank 4 is located on the side of the support side plate 2 close to the atomizing nozzle 15.
[0023] The PLC controller 3 is fixedly installed on the side of the support plate 2 near the expansion roller 16, and the PLC controller 3 is wiredly connected to the first electric hydraulic rod 6, the water pump 9, the first servo motor 19 and the second servo motor 20, respectively, to facilitate the automatic operation of the equipment.
[0024] The drive end of the first servo motor 19 is fixedly installed at the end of the first rotating shaft 12 away from the limiting groove 14. The first servo motor 19 drives the first rotating shaft 12 to rotate, thereby driving the expansion roller 16 to rotate and extrude the forging. The drive end of the second servo motor 20 is fixedly installed at the end of the second rotating shaft 18 near the equipment groove 10. The drive end of the second servo motor 20 drives the second rotating shaft 18 to rotate in the opposite direction to the rotation direction of the first rotating shaft 12, so that the forging is subjected to the same force direction and drives the forging to rotate.
[0025] Working principle: During use, the control program is first set through the PLC controller 3, and then the water tank 4 is filled with water. When the edge expansion operation is started, the PLC controller 3 controls the second electric hydraulic rod 13 to retract. The extension end of the second electric hydraulic rod 13 drives the lifting frame 11 to move upward. The corresponding edge expansion pressure roller 16 is selected according to the required expansion size. The edge expansion pressure roller 16 is inserted into the outside of the first rotating shaft 12 by external force, and the limiting block 17 is inserted into the inside of the limiting groove 14. Then, the edge expansion pressure roller 16 is fixed on the first rotating shaft 12 by the nut. Then, the heated forging is nested into the outside of the second rotating shaft 18 by external force. Then, the PLC controller 3 controls the second rotating shaft 18 to move upward. An electric hydraulic rod 6 extends, and its telescopic end pushes the support rod 7 upward until the inner side of the top of the support rod 7 is tightly against the outer side of the bottom of the second rotating shaft 18, with the forging located between the support side plate 2 and the support rod 7. Then, the PLC controller 3 controls the extension of the second electric hydraulic rod 13, and its telescopic end drives the lifting frame 11 downward. The movement of the lifting frame 11 drives the first rotating shaft 12 downward, and the movement of the first rotating shaft 12 drives the expanding pressure roller 16 downward until the inner side of the bottom of the expanding pressure roller 16 is tightly against the top of the forging. At this time, the PLC controller 3 starts the expanding program, and the PLC controller 3 controls the water pump 9 and the first servo motor. The first servo motor 19 and the second servo motor 20 are started. The water pump 9 delivers water from the water tank 4 to the atomizing nozzle 15 through a water pipe. The atomizing nozzle 15 sprays water onto the outside of the expanding roller 16 for cooling. The drive end of the first servo motor 19 drives the first rotating shaft 12 to rotate, which in turn drives the expanding roller 16 to rotate. The drive end of the second servo motor 20 drives the second rotating shaft 18 to rotate. The rotation direction of the second rotating shaft 18 is opposite to that of the first rotating shaft 12, so that the forging is simultaneously subjected to force and rotates in the same direction. The groove on the outside of the expanding roller 16 fixes the shape of the forging. While rotating, the PLC controller 3 controls the second electric hydraulic rod 13 to slow down. The forging is slowly extended. The telescopic end of the second electro-hydraulic rod 13 drives the expanding pressure roller 16 to move downward to extrude the forging. The extrusion of the expanding pressure roller 16 and the second rotating shaft 18 makes the edge of the forging thinner and thinner, thereby increasing the diameter of the forging. After the expansion is completed, the PLC controller 3 controls the water pump 9, the first servo motor 19 and the second servo motor 20 to shut down. Then, it controls the second electro-hydraulic rod 13 to retract. The telescopic end of the second electro-hydraulic rod 13 drives the expanding pressure roller 16 to move upward away from the forging. Then, it controls the first electro-hydraulic rod 6 to retract. The telescopic end of the first electro-hydraulic rod 6 drives the support rod 7 to move downward away from the second rotating shaft 18. Then, the expanded forging can be removed by external force.
