Abstract：

For the problem of toothed flat steel produced by traditional punching machine such as pool precision, high costs and low efficiency, a new type of automatic punching machine for toothed flat steel was designed by analyzing the characteristics of the toothed flat steel. It is emphatically introduced the overall structure which including feeding device, punching device with conjugate cam mechanism, punching die used to produce toothed flat steel, hydraulic control system and numerical control system. The new type of NC toothed flat steel was manufactured. The error of punching accuracy is no more than 0.2 mm, punching speed is up to 24-30 m·min-1. The punching machine can produce toothed flat steel with uniform tooth type and tooth pitch efficiently, and all indicators have reached the national standard.
