At this time, the uppermost end surface of the beating block is lower than the upper plane of the conveying belt. When the cylinder piston rod is retracted, the flapping block rotates around the hinge point, and the flapping plane is in parallel contact with the plane of the edge of the sheet. An elongated hole is arranged in the middle of the flapping bracket to provide a guiding function for the connecting rod hinge shaft b. When the piston rod extends or retracts, the connecting rod hinge shaft b runs in the elongated hole;

7. It can be applied to the centering and positioning of single sheet and double sheet: when one sheet is used, it can be centered and positioned according to the set position, and when two sheets are used, the left and right positions can be centered according to the set position. ;

8. It can be applied to sheets of different sizes: the stroke adjustment of the flapping part is adjusted by the servo motor driven screw;

9. After the position of the sheet metal is centered, the position and posture of the sheet metal grasping robot is fixed, and there is no need to adjust the position and posture of the sheet metal grasping robot with high precision at any time; improve the rhythm of the robot placing the sheet into the mold.

10. When replacing sheets of different sizes, there is no need to manually re-install the position of the beating mechanism. The lead screw is driven by the servo motor to automatically adjust the beating position, which reduces the labor intensity of the operator and saves time.

11. A buffer spring is set at the stop of the rear flapping mechanism. When the sheet is pushed by the front flapping mechanism, the sheet collides with the block of the rear flapping mechanism, and the buffer spring prevents the sheet from rebounding and reduces noise. effect.
