4. A spring steel milling process according to claim 3, comprising the steps of:
step one, driving the two positioning plates (603) at the two sides to be far away from each other through a driving mechanism, then placing the spring steel (7) between the two positioning plates, and driving the two positioning plates (603) at the two sides to be close to each other through the driving mechanism after the placement is completed so as to clamp and fix the spring steel (7) between the arc grooves (605);
step two, starting a first motor (402) to drive a first screw (4) to rotate, synchronously driving a U-shaped frame (503) to move towards a grinding roller (2) in the process of upper moving of the first screw (4) by the first nut (401), and synchronously driving a spring steel (7) to move towards a sharpening through groove (203);
step three, when the spring steel (7) is driven to move towards the inside of the sharpening through groove (203), the second rack (301) is meshed with the second gear (202) to drive the grinding roller (2) to rotate;
step four, after two or three rounds of reciprocating rolling at a group of sharpening through grooves (203), driving the spring steel (7) to reset, driving the second screw (501) to rotate by the second motor (5), and synchronously driving the spring steel (7) to horizontally transfer by the positioning mechanism in the process of transferring on the second screw (501) by the second nut (502) so as to be matched with the next group of sharpening through grooves (203);
and fifthly, repeating the second step to the fourth step, and sequentially sharpening the spring steel (7) along the array direction of the rolling grooves (201) with gradually reduced width and depth.
