Bending & punching Devices

Plate bending devices in which a workpiece is held between the forming die and the secondary clamp block of a plate and tube bending fixture. When the primary clamp block of the plate bending fixture is rotated to achieve a bending moment in the workpiece, the workpiece is bent until the primary clamp block revolves to a top point where rotation ceases and the workpiece is formed exactly into the expected angle of bend.
At the same time, the primary clamp block cushioning mount has shock absorbing springs inside and the pressure cylinder mount absorbs shock from the force generated when force is applied to the workpiece during bending which is uniformly dispersed by the primary clamp block such that the workpiece is formed precisely at the expected angle of bend, with the workpiece surface remaining smooth and free of pressure marks.

A Plate punching devices includes a plurality of punching units arranged in a side-by-side fashion on a substantially horizontal working surface.

The device includes a plurality of punches and dies of different shaped, and a moving assembly, for supporting a holder frame, which moves a workpiece along both X- and Y-axes on a working table. A control unit is provided for inputting punching positions on the workpiece as well as the shape(s) of the holes to be punched, as well as for controlling operation of the moving assembly and punching units in response to inputted data, and for moving the punching positions of the workpiece below the desired punching units to perform punching operations.

The punching units each comprises a substantially -shaped supporting member in which a piston is provided for moving a punch upwardly and downwardly. The punch is provided in one arm of the -shaped support member, with a corresponding die in a lower portion of the support member.
