Incidentally, the calculation of the thickness of the electrodeposited layer is performed based on information in which the core wire resistance value and the thickness of the electrodeposited layer which are previously mounted in the calculation circuit are associated (step 15).
  • the electrodeposition layer calculation section 43 determines whether the calculated thickness of the electrodeposition layer has reached the set thickness (step 16), and if the thickness has not reached the set thickness, The switching section 41 is activated, and the current control section 44 starts energization at the second current value (step 22) according to the switching command (step 21). On the other hand, when the electrodeposited layer having the set thickness is obtained, the power supply to the core material 31 is terminated (step 17). Although the switching unit 41 in step 13 is started at different preset (shorterly shorter from start) time intervals, it may be started at equal time intervals.
  • step 12 the electrodeposition using the first current value is performed for a predetermined time, but the electrodeposition based on the core wire resistance detected by the core wire resistance detection unit 42 is performed like the electrodeposition using the second current value. It is also possible to conduct electricity according to the thickness of the electrodeposition layer. That is, the processing of steps 13 to 16 may be performed instead of step 12.
  • the example shown in FIG. 7 is a metal ferrule manufacturing apparatus 200 in which the metal ferrule manufacturing apparatus 100 shown in FIG. 1 is arranged in five rows (100-1 to 100-5) to improve mass productivity.
  • the metal ferrule manufacturing device 200 includes an electric bath management device 5 for centrally managing the electric baths of the five electric baths 1 (1-1 to 15), and an electric bath management device 5 in these electrolytic baths 1.
  • An impurity removing device 6 for removing impurities from the electrolytic bath (1-1 to 15) is provided in parallel.
  • the electric bath management device 5 includes a heater and a concentration analyzer, and keeps the temperature state and the concentration state of the electrolytic solution 11 constant.
  • the impurity removing device 6 is provided with a mesh filter means 61 and a dust removing means 62, and is used in the electrodeposition process. To remove fine impurities.
  • the metal ferrule manufacturing apparatus (100-1 to 100-5) included in the metal ferrule manufacturing apparatus 200 has the same structure as the metal ferrule manufacturing apparatus 100 described above.
  • the core support means 3 outside the figure holds the core 31 horizontally through the current-carrying electrodes 40a and 40b, and the core 3 1
  • the metal holding means 2 is horizontally disposed at a position facing the metal.
  • the metal holding means 2 is held by a work holder 12 and arranged in parallel on an electric bath 1 along a horizontal plane.
  • the swing portion 23 swings the swing frame 2.31, and swings the metal holding means 2. As a result, a metal ferrule having high coaxiality can be produced in a larger amount.
