3. Manipulator
- The functions of changing sides, rotating and moving are realized in the horizontal plane
- C-type structure, more flexible and freer space
- Servo driver, linear guide, high precision
Bending manipulator has the function of positioning and rotary transportation of sheet metal. The utility model is composed of a central positioning device, a rotating device, a clamping device, a mobile conveying device and a base. After the sheet is in place, it realizes the function of centering and pressing, and cooperates with the main machine of folding to realize various folding process actions.
Positioning pushing device will place the plate to be folded in the X and Y directions, which can realize the pre-positioning between the plate and the machine tool. There are two groups of positioning blocks, which can locate the corner and the edge respectively. The combination has nine positioning functions, and the Y direction of the left and right positioning seat can be adjusted (+50mm) to adapt to the positioning function of various sheets.
Compressing device realizes reliable compaction by servo-driven screw driving connecting rod, and can realize reliable clamping of plates of different materials and thickness.
Rotating device realizes the rotation of the rotating block by servo driving motor and reducer. The high precision encoder realizes closed-loop control, and the rotation accuracy is stable and reliable.
