Rongwin produces various types of punch presses to meet the production needs of different customers. This series of power press adopts rotating key positive clutch, which has a simple structure and is convenient to operate and maintain, achieving smooth operation, low impact and low noise; J23-25 open type inclinable press machine is the first to adopt rolling bearing rather than the commonly used sliding bearing (copper bearing) for the transmission gear, making the transmission gear more wear-resistant and avoiding loud noises of gears causedby the quickly worn copper bearing; The 80T-level and above press machine all adopt the structure of pneumatic dual balance cylinder, which has small fluctuation of the balance force and it balances the slider and the upper die, which can cause the lathe unstable. And it canalso avoid the clash and noise caused by the converse force of gears in transmission, and avoid accidents caused by the falling of slider when the brake fails or the connecting rod ruptures.
