Metal material processing machine

A metal material processing machine along a feeding direction comprising a feeding device, a moving device, a guiding device, a first rail driven device, a second rail driven device, a third rail driven device, and a fourth rail driven device, wherein:

• the feeding device is configured to feed a metal material along the feeding direction;
• the moving device is configured to move the metal material forward from a starting point along the feeding direction, the metal material is guided by the guiding device, the metal material is disengaged from the moving device, and the metal material is configured to move along a direction opposite to the feeding direction until backs the starting point;
• the first rail driven device is aligned with the feeding direction;
• the second rail driven device is aligned with the third rail driven device, the second rail driven device and the third rail driven device are perpendicular to the feeding direction respectively, and the second rail driven device and the third rail driven device are disposed at two sides of the feeding direction respectively;
• and
• the fourth rail driven device is aligned with the feeding direction, and the fourth rail driven device is opposite to the first rail driven device.
