Crankshaft quenching machine

Crankshaft quenching machine

The crankshaft quenching machine tool is suitable for various crankshaft quenching, and the heating and cooling process parameters of each inductor can be independently set. The quenching machine tool adopts a dedicated thin transformer and power pulse distribution technology, which can ensure that the hardening layer in the circumferential direction of each quenching part is consistent. The independent sensor suspension technology and crankshaft clamping Assistive technology can be used for quenching a variety of crankshaft products to reduce crankshaft quenching deformation.
Main configuration of crankshaft quenching machine tool
1. The equipment mainly includes: crankshaft quenching machine tool, IGBT medium frequency power supply, quenching liquid circulation cooling device, pure water cooling circulation device (including low-pressure cooling system 0.1-0.2Mpa, 0.6-0.8Mpa high-pressure cooling system), electrical control system, chiller unit, etc; The equipment can perform journal quenching and fillet quenching on various four and six cylinder engine crankshafts with a length of 500-1500mm.
2. Automatic monitoring and protection of temperature, pressure, and flow of quenching liquid and cooling water.
3. The control system has fault protection, indication, and alarm functions.
4. The power chuck, tailstock, and transformer lifting drive mechanism of the quenching machine tool are pneumatic; Loading and unloading mechanism; Adopting a reciprocating dual level trolley, the motor drives the synchronous belt transmission, and the lifting power of the parts is cylinder.
5. Bed head and bed tail: The rotating cylinder power chuck is clamped, and the rotation is driven by a servo motor. At the same time, the position of the tail seat can be electrically adjusted to adapt to different lengths of crankshaft quenching.
6. The crankshaft movement system adopts a servo motor and ball screw to drive the crankshaft to move horizontally, and the guide rail adopts a rectangular linear guide rail. 
7. Load feed: The power for load rise and fall is cylinder.
8. The machine tool is equipped with 6-15 sets of load systems (including quenching transformers, capacitors, inductors, etc.), and each set of loads can be switched and operated independently in sequence; The spacing between transformers can be manually adjusted between 0-100mm.
9. The process parameters for load operation can be independently set.
10. The clamping of the crankshaft adopts central hole and end face positioning, and the headstock and tailstock adopt pneumatic self centering power chucks. The clamping process of the crankshaft is automatically completed, and the tailstock can freely expand and contract according to the expansion amount of the crankshaft during the quenching process; The adjustment of the clamping length adopts a screw electric adjustment.
11. The machine tool control system can select Siemens/Mitsubishi/FANUC/PLC+touch screen and other control systems; The various actions of the machine tool have interlocking protection, and the various process parameters of equipment operation (including voltage, current, heating time, cooling time, heating power, frequency, spray flow rate, etc.) have display or setting functions.
12. In addition to overvoltage, overcurrent, phase loss, and water pressure fault protection, the power supply also has voltage limit, current limit protection, minimum value protection, incoming line voltage too high protection, starting current too high protection, and water temperature protection. It is also interlocked with the supporting machine tool for protection, and the supporting machine tool cannot be started without the power supply ready.
13. Process parameter monitoring can monitor and record the heating parameters of each heating part.
