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
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.

5. Main structure and feature
Company independently designs, imported key drive and control parts. The unit mainly consists of loading pallet, loading device, plate conveying device, flanging machine, feeding machine, discharging device and electrical control system.
High strength frame
◆ The frame adopts an open "C" structure, which is good for opening. The frame is made of steel structural parts, and after welding, the internal stress is removed by tempering the large tempering furnace.
◆ By finite element analysis, the frame has high strength and low deformation
Mechanical servo bending system
◆ Using the link type flanging mechanism, high transmission rigidity and good precision can be achieved.
◆ Process adjustment is convenient. Under the control of numerical control system, various folding modes can be realized and have safety protection function.
◆ The stroke and speed of the servo folding beam can be adjusted according to the processing requirements, so that higher comprehensive folding efficiency and better folding quality can be achieved.
Standard worktable
◆ Composite steel ball, brush work table, reduce resistance and surface damage effectively.
◆ Tilting table is more convenient to maintain.
Automatic loading system
◆ Adopt new feeding system, adopt servo drive positioning, high efficiency and smooth operation.
◆ Compact layout, beautiful and simple, high reliability, saving space
◆ Standard panel thickness measuring device can effectively solve plate adhesion.
Unloading system
◆ Under the shear part, there is a special steel belt output channel for the residual waste, which can avoid the failure of the feeding belt of the slender waste card.
◆ There are 2 outlet channels for workpiece: lateral tilting transportation, which is convenient for manual material collection; Roller conveyor forward transmission, left plate follow-up processing interface.(additional optional equipment can be used to add robot blanking and stacking, welding system, etc.)
