1 initial state of equipment: the first lifting workbench 11 on the left side of the main machine 1 is at a lifted high position, namely, a height difference value between the high end and the low end of a bending workpiece is higher than that of the reference workbench 12; the second lifting workbench 13 and the third lifting workbench 14 on the right side of the main machine are at the lowered low positions, namely the heights of the second lifting workbench and the third lifting workbench are the same as the heights of the upper part 12 of the reference workbench;

2, placing the bent workpiece on the first lifting workbench 11 and the reference workbench 12, wherein the high end and the low end of the bent workpiece are in a parallel state;

3, positioning mechanisms on the first lifting workbench 11 and the reference workbench 12 push the bent workpiece to the positioning wheel for positioning, namely side positioning;

4, driving mechanisms on the first lifting workbench 11 and the reference workbench 12 laterally press the side edge of the bent workpiece, and the bent workpiece is driven to move along the length direction of the bent workpiece through friction force, namely side edge driving;

5, the front end of the bent workpiece is arranged on the reference workbench, and when the bent workpiece moves to the end detection switch, an end signal is sent out, namely the front end position is determined or the front end is positioned;

6, the control system is used for carrying out value-added calculation on data of an encoder in the side detection mechanism and data of the distance between the end head detection switch and the encoder, so that the end head moving position is calculated, and the control system is used for carrying out closed-loop control on the longitudinal moving position of the bent workpiece;

7, under the action of a side driving force, the front end of the bending workpiece enters a machining area of the host, a machining auxiliary assembly mechanism on the left of the host presses the bending workpiece downwards, and a power head on the host starts to machine the bending workpiece;

8, after the main machine finishes the processing of the bent workpiece, the processing auxiliary mechanism loosens the bent workpiece, and the side driving mechanism continues to drive the bent workpiece to move forwards;

9 when the front end of the bending workpiece moves to the position of the driving mechanism on the second lifting workbench at the other side of the main machine, the driving mechanism at the left side of the main machine stops rotating, the driving mechanism at the right side of the main machine compresses the bending workpiece, and the bending workpiece is continuously driven to move forwards, namely relay driving is carried out;

10 when the lower end part of the bending piece enters the roller of the second lifting workbench at the other side of the main machine in the moving process of the bending workpiece, the high end part of the bending piece is still on the roller on the first lifting workbench; at the moment, the first lifting workbench and the second lifting workbench synchronously descend to enable the whole bent workpiece to vertically descend, the left side of the main machine descends to the height of the reference workbench, the right side of the main machine descends by a height difference, and the height of the bent workpiece is supported at the same time to ensure that the relative positions of the high end and the low end of the bent workpiece are unchanged; the bending workpiece can be continuously driven by the driving mechanism; namely, the bending workpiece stably descends and can be driven continuously.

11 when the bending workpiece continues to move, the front end of the bending workpiece can be relay-driven through the driving mechanism on the bending workpiece after reaching the lower third lifting workbench;

12, after all the height parts at the rear part of the bending machine enter a second lifting workbench, the second lifting workbench is lifted to support the high-end part of the bent workpiece, and the second lifting workbench can be driven to move continuously until the machining is finished;

and 13, the bent workpiece can be stably and accurately conveyed through the main machine in a lifting support, side driving and relay driving mode, so that the full-length machining of the bent workpiece by the main machine is adapted.

Technical scheme of the utility model not be restricted to the utility model the within range of embodiment. The technical contents not described in detail in the present invention are all known techniques.
