Feeding device of three-dimensional punching production line

The utility model discloses a feeding device of a three-dimensional punching production line, and relates to the technical field of profile punching production lines. The device comprises a workbench, a material pushing assembly is slidably arranged on the upper portion of the workbench. A linear driving assembly used for driving the material pushing assembly to move is arranged on one side of the material pushing assembly. A clamping assembly and an adjusting assembly are arranged on the material pushing assembly. The adjusting assembly matched with the clamping assembly is arranged on the pushing assembly, so that the position of the long profile can be corrected, and the length direction of the long profile can be parallel to the driving direction of the linear driving assembly; the distance between the middle line of the long profile and the two oil cylinder type punching mechanisms located on the side of the three-dimensional punching device is equal, so that the problems that the feeding effect is poor,
