| 摘要 |
The press brake of the invention comprises a cross bar-like pressure ram member. The two lateral ends thereof are connected each to the piston rod of a pressure bar operating cylinder. For transmitting the power exerted by the operating cylinder, there is provided an articulated joint assembly with two articulated joints which are arranged in series as seen in the power transmission direction. Thereby, a complete absence of clearance in the pressure ram driving elements can be realized and higher tolerances as far as the parallelism of the two operating cylinders can be accepted. Furthermore, an operational tilting of the pressure ram member with relatively high tilting angle is possible.
