    • A thermoforming trim press has one or more connecting arms for a movable platen which each have a pivotal connection between the adjacent ends of two adjacent sections into which each connecting arm is divided. The pivotal connection is normally locked to keep the sections in end to end alignment during normal press operation, but can be released to allow pivoting between the sections to be able to draw the movable platen further back from the normal retracted position to increase the available clearance when changing or maintaining tools mounted on the movable platen. The pivoting ability of the connecting arm sections also simplifies adjusting the stroke of the press while this is normally done by relocating a crank pin on flywheels driving the connecting arms. The change of position does not affect the movable platen when the arm sections may pivot with respect to each other allowing relocating the crank pins to adjust the stroke without requiring disassembling of the crank pins. A counterweight may be driven by the crank pins to match the press stroke adjustments and to thereby correspond the movement of the counterweight to the movement of the movable platen.
    • 热成型微调压机具有用于可动压板的一个或多个连接臂,每个连接臂在每个连接臂被分开的两个相邻部分的相邻端部之间具有枢转连接。 通常锁定枢转连接以在正常的按压操作期间将部分保持在端对端对准中,但是可以被释放以允许部分之间的枢转,以能够将可动压板从正常缩回位置进一步向后拉动以增加可用间隙 当更换或维护安装在可移动压盘上的工具时。 连接臂部分的枢转能力也简化了调节冲程的行程,而这通常是通过将曲柄销重新定位在驱动连接臂的飞轮上。 当臂部可以相对于彼此枢转时,位置的改变不会影响可动压板,从而允许重新定位曲柄销以调节行程而不需要拆卸曲柄销。 配重可以由曲柄销驱动以匹配冲压行程调节,从而对应于配重与可动压板的运动的运动。
