Round Flange Punching Machine

Working principle:

1. After setting the diameter of the circular flange, the servo motor drives the positioning mechanism to automatically position according to the size of different flange diameters.
2. Manually input the diameter and the number of input holes on the man-machine interface, the indexing plate adopts servo positioning, positioning tolerance ±1mm, when clamping the workpiece, the servo motor will rotate.
3. Round flange processing diameter range φ200 ~ φ1800mm.
4. The stamping die adopts standard modular design, and the replacement is simple and convenient during use.
5. The clamping mechanism of the index plate is completed by the servo motor with the ball screw.
6. The support frame ensures that there are six points of positioning, so that the force of the workpiece is uniform, and the workpiece is firmly held.
7. The die material is H13K, and the hardness can reach HRC60°.
8. Punching: using hydraulic slider punching method, The outer ring part of the Angle iron ring is arranged with a slider that can reciprocate along the direction of the diameter line of the Angle iron ring. The front end of the slider block is installed with a high hard punch. The inner ring part of the Angle iron ring is installed with a punching bottom die corresponding to the position where the slider is located. The slider is pulled back to a set stroke by the hydraulic cylinder, allowing the Angle ring to complete the rotation of the next punch position, while the inner ring bottom die will be retracted by the servo screw, which can be programmed according to the different specifications of the Angle ring, so that all is completed side hole punching.

9. Punching specification: semi-circular waist hole Ø10×12; Ø12×14 two specifications
10. Automatic control: machine production control is divided into manual, automatic, with an emergency stop device. The man-machine interface screen is set for touch display.

11. The equipment uses double stamping stations for punching holes, which can realize the operation of single and double holes of flanges respectively. Two servo systems such as workpiece clamping, punch moving, indexing rotation and punching displacement are adopted respectively. The height of the operating line is 950mm to 1000mm. Hydraulic power motor 5.5kw/3 phase.
