★ It is designed through adopting the high-rigidity frame structure. In addition, it is manufactured through welding high-quality steel plates and the internal stress is removed through annealing, which improves stability and reliability of precision of the complete machine greatly.
★ The double crank shafts are designed in the reverse way, which counteracts side force of the linkage slide block and improves stationarity of transmission.
★ It adopts the symmetrical design method of the two balancer devices, which guarantees the relative stationarity of the machine’s operation.
★ The precision of die adjustment can reach 0.1mm and the die adjustment is safe, convenient and reliable; heat treatment quenching and precision grinding are conducted for the gear pair and sliding pair, so the transmission is stable, the precision is high and the durability is strong.
