Device for galvanizing member-shaped substrates

Abstract

A device for galvanizing of member-shaped substrates includes a base ( 1 ), an adapter ( 5 ) supported on the base ( 1 ) for supporting a to-be galvanized member-shaped substrate ( 2 ), an upper sealing ring for securing the to-be-galvanized member-shaped substrate to the adapter ( 5 ), an annular complementary member ( 10 ) located opposite the upper sealing ring ( 3 ) and having counter-recesses complementary to a recess formed in the lower end of the sealing ring ( 3 ) and in which a respective O-ring ( 7 ) is received, with the annular complementary member ( 10 ) being mounted in the base ( 1 ) without any side clearance and sealing, together with the sealing ring ( 3 ), with the respective upper and lower O-rings ( 6, 7 ) being received in respective recess, an electrolyte region.

1 . A device for galvanizing of member-shaped substrates, comprising a base ( 1 ); an adapter ( 5 ) supported on the base ( 1 ) for supporting a to-be galvanized member-shaped substrate ( 2 ); an upper sealing ring for securing the to-be-galvanized member-shaped substrate ( 2 ) to the adapter ( 5 ) and provided at its opposite upper and lower ends with recesses for receiving respective O-rings ( 6 ,  7 ); an annular complementary member ( 10 ) located opposite the upper sealing ring ( 3 ) and having counter-recesses complementary to a recess formed in the lower end of the sealing ring ( 3 ) and in which a respective O-ring ( 7 ) is received, the annular complementary member ( 10 ) being mounted in the base ( 1 ) without any side clearance and sealing, together with the sealing ring ( 3 ), with the respective O-rings ( 6 ,  7 ) being received in respective recess, an electrolyte region; and a union nut ( 4 ) for securing an entire system of the device together  
   
   
       2 . A galvanizing device according to  claim 1 , further comprising one of pneumatic means and hydraulic means for pressing the annular member ( 10 ) against the sealing ring ( 3 ).  
   
   
       3 . A galvanizing device according to  claim 2 , further comprising double-side bellows ( 9 ) for supporting the annular member ( 10 ), and wherein the one of pneumatic means and hydraulic means includes a channel ( 14 ) formed in the bellows ( 9 ) for conducting one of pneumatic and hydraulic medium, respectively, for applying pressure to the annular member ( 10 ).  
   
   
       4 . A galvanizing device according to  claim 2 , further comprising a flat flexible diaphragm ( 17 ) for supporting the annular member ( 10 ), and wherein the one of pneumatic means and hydraulic means includes means for conducting one of pneumatic medium and hydraulic medium against the diaphragm ( 17 ).  
   
   
       5 . A galvanizing device according to  claim 3 , further comprising control means for controlling flow of the one of pneumatic medium and hydraulic medium toward the annular member ( 10 ) in accordance with a load applied to the O-rings ( 6 ,  7 ).  
   
   
       6 . A galvanizing device according to  claim 3 , further comprising control means for controlling flow of the one of pneumatic medium and hydraulic medium toward the annular member ( 10 ) in accordance with a load applied to the O-rings ( 6 ,  7 ).  
   
   
       7 . A galvanizing device according to  claim 1 , further comprising a buffer elastic support member ( 8 ,  12 ) for balancing a pressure applied to O-rings.  
   
   
       8 . A galvanizing device according to  claim 1 , further comprising bellows means ( 9 ) for further sealing the electrolyte region.
