[0026] See also Figures 1-12As shown, the purpose of this embodiment is to provide a flexible punching mechanism for water heater shell processing, including a punching frame unit 1, which is fixedly mounted on the outer surface of the mechanism frame. A mold maintenance and avoidance unit 2 is fixedly mounted on the right side of the outer surface of the punching frame unit 1, and a mold change frame unit 3 is fixedly mounted on the left side of the outer surface of the punching frame unit 1. The punching frame unit 1 includes a hydraulic servo proportional valve 101 and a driving hydraulic cylinder 102. The hydraulic servo proportional valve 101 and the driving hydraulic cylinder 102 are both fixedly mounted on the mold maintenance and avoidance unit 2. The hydraulic servo proportional valve 101 is used to control the hydraulic control system unit 10, drive the hydraulic cylinder 102, and then drive the corresponding mold punching unit 8 to complete the punching operation;

[0027] A feed side width alignment unit 4 is fixedly mounted on one side of the outer surface of the punching frame unit 1. The feed side width alignment unit 4 includes a servo motor 41. The output shafts on both sides of the servo motor 41 are fixedly connected to the left and right side lead screws 42. The outer surfaces of the left and right side lead screws 42 are slidably connected to the alignment mechanism 43. The feed side width alignment unit 4 is driven by the servo motor 41, and the left and right side lead screws 42 drive the left and right side alignment mechanisms 43 to move inward, thereby clamping the sheet metal while approaching, thereby precisely adjusting the sheet metal width.

[0028] A discharge side width alignment unit 5 is fixedly mounted on the back of the outer surface of the punching frame unit 1. The discharge side width alignment unit 5 includes a servo motor 51. The output shafts on both sides of the servo motor 51 are fixedly connected to the left and right side lead screws 52. The outer surfaces of the left and right side lead screws 52 are slidably connected to the alignment mechanism 53. The feeding robot continues to operate to move the sheet material along the product support unit 9 to the discharge side width alignment unit 5.

[0029] A mold driving unit 6 is slidably connected to one side of the outer surface of the mold changing frame unit 3. The mold driving unit 6 moves on the guide rail of the mold changing frame unit 3. After the mold punching unit 8 receives the product processing instruction, the mold driving unit 6 moves along the guide rail, drives the sheet metal to move to the bottom of the mold punching unit 8, and then drives the hydraulic cylinder 102 to drive the cutter head at the bottom of the mold punching unit 8 to perform the punching operation. The mold punching unit 8 is equipped with a sheet metal fixing part and a bolt so that the cutter head of the mold punching unit 8 can be replaced, and can be flexibly changed at different positions to meet the punching requirements of different positions;

[0030] A die punching unit 8 is provided on one side of the outer surface of the die inspection and avoidance unit 2. The die punching unit 8 performs the punching operation under the drive of the die driving unit 6. A guide rail locking unit 7 is fixedly installed on the outer surface of the punching frame unit 1.

[0031] A product support unit 9 is fixedly installed on the outer surface of the punching frame unit 1, and a hydraulic control system unit 10 is fixedly installed on the outer surface of the mold inspection and avoidance unit 2. The hydraulic control system unit 10 is set to drive the hydraulic cylinder 102, and then drive the corresponding mold punching unit 8. The punching unit 8 slides downward, causing the cutter head at its bottom to punch the workpiece.

[0032] When the present invention is used in practice, the front-end feeding manipulator automatically feeds the sheet into the working area of ​​the punching frame unit 1, and the feed side width alignment unit 4 is driven by a servo motor 41, and the alignment mechanism 43 driven by the lead screw 42 on the left and right sides is precisely adjusted to the sheet width. After the adjustment is completed, the guide rail locking unit 7 controls the locker through the solenoid valve to lock the guide rail to ensure the accuracy and stability of the alignment mechanism 43. The feeding manipulator continues to execute the command and moves the sheet along the product support unit 9 to the discharge side width alignment unit 5. On the discharge side, it is also driven by a servo motor 51, and the left and right sides are driven to adjust the sheet width. The alignment mechanism 2 53 on the side screw 2 52 makes precise adjustments to the width of the sheet. After receiving the product processing instructions, the mold drive unit 6 moves along the guide rail to drive the mold punching unit 8 to perform the punching operation. The hydraulic control system unit 10 is controlled by the hydraulic servo proportional valve 101 to drive the hydraulic cylinder 102, and then drive the corresponding mold punching unit 8 to complete the punching action. The feeding robot continues to feed the material, and the mold punching unit 8 punches the predetermined positions on the sheet in turn. After the punching operations at all the predetermined positions are completed, the sheet is sent out of the punching frame unit 1 by the feeding robot to complete the entire punching process.
