In order to solve the problem of automatic stamping production in a train carriage parts manufacturing enterprise, according to the process characteristics of a company’〖KG-*2〗s stamping production line,a loading and unloading manipulator was developed for the 35MN hydraulic press. A set of automation transformation program for the whole line was proposed in order to realize the automatic production from feeding to product palletizing.The production line consisted of material table, secondary positioning table, truss manipulator, gripper and hydraulic press, which could meet the automation production of various stamping parts, effectively improve the production efficiency of the stamping industry, improve product quality and save processing costs.The tested results show that the production line can be used to realize the automatic production of any sheet with the length of 1 500~4 000 mm, width of 900~1 280 mm and weight of 110 kg,and the operating cycle is 38 s,meeting the manufacturing needs. This automated transformation production line is stable in operation, easy to operate, and highly adaptable.
