Station type SP4/1x160 for pressing and welding a sleeve on shock absorber piston rod


The rotary table with four instruments was used in the project: 1. piston rod loading, 2. feeding and pressing of the sleeve, 3. welding in four points, 4. weld strength test. Due to the construction of the device, the station is equipped with a Tox pneumohydraulic system, which allows to obtain considerable pressing force from small cylinders. On the station there is a a closed loop chiller used as well as Nedermann exhaust system. TECNA welding controller and Siemens PLC control systems were used to control the device.
