4.2  Buffer device
Adopt no-pit material storage way, which is convenient to install
equipment and use safely

4.3   Feeding device
Feeding device is the core part of shear machine; adopt the closed loop control mode. Device is composed of feeding roller, length measuring wheel, with limitation, servo width adjustment, servo feeding system and so on. The feeding roller is composed of an upper roller and a lower roller, the lower roller is an active roller, the upper roller is a pressing roller, and the lower roller is uniformly pressed on the lower roller by a certain air pressure, so as to ensure that the material is stable and the surface does not run in slip.

4.4  V-notching device
V-notching device is used for punching and cutting of yoke V type gap and center leg, which is composed of the base ,cutter(including the upper blade, the lower blade, blade holder, blade body ),servo motor(including power control of punching and cutting, the control of horizontal movement),precision ball guide post guide sleeve, horizontal adjustment linear guide rail, ball screw and so on. According to product width and notching depth to adjust v-notching device automatically by touch screen operation, which meet the work requirements of center leg and yoke, etc.
