Described large-scale workpiece hard chrome plating double utmost point frame is provided with insulation web plate (8) between the main pole thick stick (7) at consequent pole frame (6) and its two ends, both are fixedly connected by the insulation web plate; Described connection insulcrete (8) one ends are connected with consequent pole frame (6) by holding bolt, and the other end is connected with main pole thick stick (7) by holding bolt, perhaps connect described consequent pole frame (6) and main pole thick stick (7) is provided with a reinforced insulation plate (9) in addition.
Described large-scale workpiece hard chrome plating double utmost point frame, the outboard end of the main pole thick stick (7) of double utmost point frame are provided with to hang and hang head (13).
Useful positively effect of the present utility model:
1, the utility model large-scale workpiece hard chrome plating double utmost point frame, adopt two single station utmost point framves to be combined into double diverter pole frame, direct supply of former plating tank configuration is changed into the design of two direct supplys of configuration, can two workpiece of a plating, two power supply parallel runnings during the plating large-size workpiece have improved the work capacity of direct supply; Two power supplys can be controlled respectively when plating small dimension workpiece, work independently, and have improved the coating bath working (machining) efficiency.Through producing checking, two direct supplys and two were one when this covering device had been realized large-size workpiece one groove single-piece, and the work capacity of direct supply is doubled; Two of small dimension workpiece one grooves, two direct supplys work independently, and control respectively, have guaranteed the electric current of electroplating technology requirement, have improved working (machining) efficiency, and the coating bath working ability is doubled.
2, the utility model large-scale workpiece hard chrome plating double utmost point frame has been realized the shunting power supply and the parallel operation of direct supply, and reasonable in design, simple in structure, result of use is good, helps saving production cost.Adopt the diverter pole frame when processing less size workpiece, two workpiece of plating in the coating bath, workpiece of every power supply plating, current parameters is controlled respectively, has guaranteed the plating quality of every workpiece, and has improved throughput.Adopt the utmost point frame that confluxes during than large-size workpiece in processing, workpiece of two direct supply platings in parallel has satisfied the plating needs of large-size workpiece, has improved the working ability of large-size workpiece.
