Crankshaft Quenching Machine

Crankshaft Quenching MachineConfigurationThis equipment mainly consists of crankshaft quenching machine, IGBT MF power supply, quenching liquid circulation cooling system, purified water cooling circulation system (including low-pressure cooling system 0.1-0.2Mpa, 0.6-0.8Mpa high-pressure cooling system), electric control system, chiller and the like. The equipment can do  journal quenching or fillet hardening for all kinds of four-cylinder and six-cylinder crankshafts with a length of 500-1500mm.Automatic monitoring protection of the temperature, pressure and flow rate of quenching liquid and cooling water. The control system has the function of failure protection, indication and alarming.The power chuck, tailstock and transformer lifting driving mechanism of the hardening machine are pneumatic; the loadding and unloading mechanism adopts a reciprocating type double-position trolley driven by a motor to synchronously drive; and the lifting force for parts is from an air cylinder.Machine head and machine tail: the machine head and machine tail are tightly clamped by the power chuck of a rotation air cylinder and driven by a servo motor to rotate, at the same time, the tail stock position can be electrically adjusted to fit for the quenching of the crankshaft with different lengths.Crankshaft moving system: Servo motor and ball screw are adopted to drive the crankshaft to transversely move; and the guide rail adopts a rectangular linear guide rail.Load feeding: The power for load ascending and descending is from the air cylinder.The machine is equipped with 6~15 sets of load systems (including quenching transformer, capacitor, inductor and the like); each set of load system can work independently by sequentially switching; the distance between transformers can be manually adjusted by 0-100mm.The technological parameters of load working can be set independently.The holding of the crankshaft adopts a center hole and an end surface for positioning, the machine head and
