YL89 series hydraulic press for automobile main sill forming
·  Main Features:
·  YL89 series hydraulic press for automobile main sill forming
■ The machine tool may operate in a single set or together with other machines.
■ The beams of the machine tool are in welded structure,and are tempered as a whole.The machine,processed by means of a large-sized ground type milling and boring tool,is marked with high precision.
■ The machine body is in a multi-column structure.The surface of the columns has gone through medium-frequency tempering treatment,and is marked with high strength,high rigidity and high wearing resistance and tensile strength.
■ An imported displacement sensor is adopted for detecting the slide block travel and giving signals.The machine has closed loop control,electrohydraulic proportional pump;and the oil cylinder is marked with excellent synchronization and the slide block is marked with high performances of eccentric load resistance.
■ The machine tool is fitted with a unique electrical cabinet,and has Mutsubishi PLC+touch screen control.Concentrated operation can be achieved by achieved by means of an operating panel.In the semi-automatic operating conditions,the operating modes include the fixed pressure mode and the fixed travel mode.In the fixed pressure mode,the machine has the function of retaining the pressure and extend the time as well as automatic return.
■ The machine tool has a full series of safety devices including double-hand operation,emergent stop,overload protection,eccentric load protection,guardrails,etc.
