In addition, the working table of the traditional five-shaft transmission type mechanical press can only reach about 4.5 meters at most, and the main transmission structure is shown in fig. 3, while the working table of the traditional six-shaft (high-speed stage transition gear) transmission type mechanical press can only reach about 5.5 meters at most, and the main transmission structure is shown in fig. 4 and 5. Taking a six-shaft transmission type mechanical press as an example, when the six-shaft transmission type mechanical press works, the high-speed stage driving gear shaft A5 transmits a revolving moment to the left intermediate gear A3, the left intermediate gear A3 is fixed on the left intermediate gear shaft A4, the left intermediate gear shaft A4 transmits the revolving moment to the left eccentric gear A2, and the left eccentric gear A2 drives the left connecting rod A1; meanwhile, the high-speed stage driving gear shaft A5 transmits the revolving torque to the high-speed stage transition gear A7, the high-speed stage transition gear A7 transmits the revolving torque to the right intermediate gear A9, the right intermediate gear A9 is fixed on the right intermediate gear shaft A8, the right intermediate gear shaft A8 transmits the revolving torque to the right eccentric gear A10, the right eccentric gear A10 drives the right connecting rod A11, and the left connecting rod and the right connecting rod change the revolving motion of the eccentric shaft into the linear motion of the sliding block and change the revolving torque into the pressing force.
At present, due to the wide application of the multi-station mechanical press, more and more users need the multi-station mechanical press with a larger working table, and the requirement of a die can be met generally by more than 6.5 meters. The main transmission structure of the traditional five-axis and six-axis transmission type mechanical press can not meet the requirements of a working table surface and the unbalance loading resistance, and finally, various design parameters of a main transmission system can not be reasonably matched. Therefore, the difficulty of developing a large-sized multi-station mechanical press is increased.
