AUTOMATIC DC-BASED MEDIUM FREQUENCY MACHINE FOR THE BRAZING OF ALTERNATOR STATORS CONDUCTOR ENDS (ACM71.01)
ÀÑÌ71.01 is an automatic DC-based 1000Hz inverter type machine, designed for the automatic brazing of the rectangular conductor ends of the alternator stator. All operations, except for the stator loading and unloading, are performed automatically including the feeding of the required length of brazing strip. A linear displacement gauge is provided on the machine for precise control of the depth of penetration of the electrode on the brazing joint that allows completing the operation after preset displacement. The pressing force of the brazing electrode is controlled by a proportional electro-pneumatic pressure regulator, the parameters of which can be set up directly on the MMI.
Machine frame is made out of aluminum profiles with steel supporting pate, on which the following main machine units are disposed:
- Stator core locating and indexing mechanism;
- Steel plates column carrying the brazing transformer and the shifting mechanism of the two electrodes;
- Brazing strip feeding mechanism, consisting of brazing strip reel support, brazing strip retaining mechanism, cylinders, clamps and brakes that actuate the feeding to the preset length, as well as forks and brazing strip guideways.
Initial stator core positioning and all technical parameters of the brazing process are controlled through a Mitsubishi PLC.
ÀÑÌ71.01 provides high quality of the process by ensuring implementation of the latest technology for brazing control.
Approximate capacity: 15-20 stators/hour for 96-slot stator variety
