Automatic die changing device

It has functions of folding and avoiding, automatic combination and so on. It is convenient to process all kinds of box parts. The die changing device consists of an intermediate avoidance die, a standard segment die, a clutch moving device and a rotating insert die device.

 1)segment die driver  2)segment die  3)insert die  4)mediate avoid device  5)insert adjusting device

During bending box, the side edge of the first fold makes the pressing die unable to move up and down directly, so there must be avoidance action. The principle of process avoidance is that the middle avoidance die moves on both sides and the standard section die moves towards the middle so that the die passes over the folded two sides. It should be noted that due to the structural constraints, the corresponding width of the workpiece should be in line with the following table.

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.

1)positioning device  2)rotating device  3)clamping device  4)moving bracket   5)holder

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.
