Abstract: It addresses the automated feeding operation of the medium-frequency furnace in the molybdenum rod hot rolling production line of an unmanned workshop. An automatic rod lifting and transporting device was designed,with theoretical analysis conducted on its lifting mechanism and hoisting mechanism. The maximum thrust and stroke required for lifting,pushing,and hoisting actions were calculated and determined. An integrated transport structure capable of omnidirectional movement was designed,featuring a hub motor nested within a Mecanum wheel. To validate the structure′s rationality and stability,dynamic virtual simulations and physical prototype testing were conducted. Results confirm the device meets operational requirements with a sound structure and stable performance,yielding the following conclusions. At the start of lifting,compression between bars causes fluctuations in lifting speed and acceleration,potentially increasing the probability of bar drop. When designing the acceleration and deceleration curve for a lifting servo cylinder,it can be set as a curved acceleration to achieve smoother and more gradual speed and acceleration;prototype testing confirmed that this device effectively improves production efficiency and reduces labor intensity for workers.
