Problems solved by technology

This also brings new problems: the calculation of the conversion relationship between the motor rotation motion and the vertical slider's up and down motion is complicated, the electrical control requirements are high and difficult, and the full load stroke is small
Its disadvantages are: the calculation of the vertical slider’s up-and-down motion conversion relationship is complicated due to the double superposition of the crank and the toggle, and the mechanical structure is more complicated, and the required height is larger.
Therefore, the required motor power is relatively large, and the requirements for the dynamic characteristics of the motor are relatively high.
