Design and Optimization of a Flexible Transferring Device with Variable Pitch for High-speed Bar Stock

To deal with the existing problems such as lower flexible work reliability, speed limit in downstream machine caused by invariable pitch in the transferring device of high-speed bar stock, the working principle of a flexible transferring device with variable pitch was proposed, and the transferring process and the motion interference of the bar stock were analyzed. In order to improve the flexible transferring reliability of the bar stock, the multi-objective optimization of device''s structure was presented. The results have shown that the axial braking process of the bar stock is improved, the transferring speed difference and the maximum pressure angle of the cam are reduced, and the rationality of optimization design is verified through simulation. The device has the advantage of accurate location, steady transferring, gentle axial braking process, and variable pitch, which is beneficial to the enhancement of production ability in downstream machine.
