IN-LINE INDUCTION HARDENING SYSTEM FOR TRANSMISSION SHAFTS
In-line 4-station induction hardening system with automatic loading and unloading by Robot for the treatment of transmission shafts
4-STATION VERTICAL HARDENING MACHINE FOR TRANSMISSION SHAFTS WITH AUTOMATIC LOADING AND UNLOADING BY ROBOT
The plant consists of the following macroblocks:
Hardening machine: induction hardening vertical machine with 4 stations, equipped with 2 induction heating generators. Each one has an output power of 300kW. They are able to work even individually, on a reduced cycle, to meet any production drops. The lunettes allow to limit the axial deformation of the shafts. The system control, entrusted to the CN Siemens 840D SL, and the specially designed mechanics, allow to treat different diameters without having to change any mechanical equipment. The same inductor is used for all types of shafts.
Measurement station: it aims to verify that the input shafts correspond to those loaded in the recipe of the CNC. Control takes place on the length, diameters and positioning of the groove. The system singularizes and positions the shafts to the distance required by the Robot clamps.
Robot: the robot, equipped with double gripper, picks the shafts from the measuring station and places them in the machine between the tailstocks, then it picks up the hardened shafts and deposits them, depending on the case, on the exit conveyor, in the quality control station or in the rejects area.
Other: drawer for quality control, cooling system for quenching liquid with tank, filter and pumps, guards and barriers equipped with interlocked closures and Parameter Control Unit.
