The pool body of the nickel-plated submerged pool 32 is in a U-shaped circular arc structure, and the length direction of the pool body is parallel to the axis of the workbench 31. The stirring assembly 33 is welded and fixed to the top of the workbench 31 on both sides through two groups of support frames 331. The dustproof shell 332 of the stirring assembly 33 is molded by ABS engineering plastic, and four groups of 304 stainless steel stirring rods 333 arranged inside the dustproof shell 332 are rotationally connected with a driven wheel one 334 through deep groove ball bearings. The spacing between adjacent stirring rods 333 is 1 / 4 of the width of the pool body. A cleaning mechanism 34 is arranged at the liquid outlet side of the nickel-plated submerged pool 32. The cleaning bin 341 of the cleaning mechanism 34 is connected with the workbench 31 through bolts, and six groups of nylon cleaning brushes 342 arranged uniformly on the inner circumference of the cleaning bin 341 are in contact with the surface of the cable through a spring pre-tightening mechanism. The bottom through holes 343 are arranged at an angle of 30° according to a hole diameter of 3mm and are penetrated through the dust collecting bin 344 made of PP material.

[0034] The two groups of limiting rollers 39 arranged at the input end of the nickel-plated submerged pool 32 are made of 45 steel with a hard chromium surface treatment and are connected with the side wall of the workbench 31 through needle bearings. The spacing between the two roller bodies is 5 times the diameter of the cable. The heating assembly 35 is an SRQ3-220V / 5kW type electric heating tube which is embedded in the dustproof bin 351 of the nickel-plated submerged pool 32 through a flange connection. The nickel-chromium alloy heating plate 352 of the heating assembly 35 is sealed with a graphite gasket at the contact surface with the pool body. The group plate 361 of the traction roller 36 is made of 7075 aluminum alloy. The GCr15 bearing steel traction rod 363 arranged in the sliding groove 362 is adjusted in height by ±15mm through an M12 fixed bolt 364. The surface of the guide roller 37 is coated with a polyurethane rubber layer. The guide roller 37 is matched with the scraping plate 38 at the liquid outlet of the nickel-plated submerged pool 32 with a gap of 2mm. The polytetrafluoroethylene scraping edge of the scraping plate 38 is arranged at an angle of 45° to the cable axis. The motor assembly 141 is a Y2-200L-4 type 30kW three-phase asynchronous motor which is directly connected with the drive gear 143 through a shaft coupling. The 20CrMnTi alloy steel teeth of the drive gear 143 are in a 1:3 speed reduction transmission with the driven wheel three 41.

The V-shaped guide groove of the two groups of restraint plates forms a dynamic constraint channel through the four-way linkage mechanism.

The inner wall of the stranded hole 134 is embedded with a polytetrafluoroethylene wear-resistant bushing, and the V-shaped guide groove of the restraint plate 133 is provided with a pressure sensor at the bottom. When the cable tension is detected to be out of limit, the stranded speed is adjusted through the electric control system linkage stranded wheel structure 14.

[0036] The motor assembly 141 adopts an explosion-proof servo motor and is rigidly connected with the steel base of the driving bracket 142 through a flange. The double-row angular contact bearing arranged in the driving bracket 142 supports the driving gear 143 to form a rotating pair. The driving gear 143 is made of 42CrMo alloy steel and the tooth surface is treated by nitriding. The inner ring is connected with the aluminum alloy hub of the stranded wheel disc 144 through a flat key to form a torque transmission structure. The stranded roller 145 is made of high-carbon steel chromium plated rod and is welded in the annular groove of the stranded wheel disc 144 at an equal angle of 90°. The end of the four groups of stranded rollers 145 is provided with a polyurethane limiting sleeve to prevent the wire from being scratched. In operation, the motor assembly 141 drives the driving gear 143 to rotate the stranded wheel disc 144 at a speed of 2-8r / min. The equidistant layout of the four groups of stranded rollers 145 makes the copper wire form a uniform spiral wrap angle when stranded.

[0038] The nickel-plated sink 32 is made of PVC and stainless steel composite material, and the contact surface with the top of the workbench 31 is transitionally connected in a circular arc shape with a radius of 15-25mm, the circular arc contact surface is sealingly connected with the nickel-plated work area of the workbench 31 through a welding process, effectively dispersing the stress concentration generated by the flow of plating solution; the group plate 361 of the traction roller 36 is made of aluminum alloy material and is vertically fixed to the outlet side of the nickel-plated sink 32, two groups of sliding grooves 362 are symmetrically opened along the longitudinal direction of the group plate 361 in a dovetail groove structure, the traction rod 363 is made of 304 stainless steel pipe with a nickel-plated surface, and the two ends are locked in the sliding groove 362 through the fixed bolts 364 made of carbon steel material with a nickel-plated surface, and the nylon limiting rings 27 arranged on the outer wall of the traction rod 363 are uniformly distributed at an interval of 30mm; the traction roller 36 is installed with an angle deviation of ±2° from the horizontal center axis of the nickel-plated sink 32, so that the cable is constrained in the axial displacement by the limiting ring 27 of the traction roller 36 after being guided out of the plating solution by the guide roller 37, and the traction rod 363 can be adjusted in height by ±50mm in the sliding groove 362 to adapt to the traction requirements of cables with different diameters; the fixed bolts 364 are matched with the anti-loose gaskets made of polytetrafluoroethylene material to ensure the positional stability of the traction rod 363 during the dynamic traction process.

[0039] The guide roller 37 and the limiting roller 39 are vertically fixed on both sides of the nickel-plated sink 32 of the workbench 31 through 304 stainless steel shaft seats, the two groups of limiting rollers 39 are made of galvanized steel roller bodies and are symmetrically arranged along the axial direction of the stirring assembly 33, the outer wall of the limiting ring 27 assembled with polyurethane is arranged at intervals of 15 cm to form a cable guide groove, and the cable guide groove is in continuous curvature with the circular arc contact surface at the top of the nickel-plated sink 32; when the cable is introduced through the traction roller 36 made of 6061 aluminum alloy, the traction tension of the cable is adjusted through the traction rod 363 in the sliding groove 362, after the traction rod 363 is locked at a height through the fluororubber sealed fixed bolt 364 at both ends, the cable is sequentially inserted into the nickel-plated liquid through the guide groove of the limiting roller 39; during the nickel plating process, the four groups of guide rollers 37 made of nylon are distributed at an angle of 120°, the V-shaped limiting ring 27 arranged on the surface is tangent to the direction of the cable, after the excess plating liquid is scraped off by the ceramic scraping plate 38, the guide roller 37 realizes the 90° turning of the cable through double-row angular contact ball bearings, the design ensures that the cable always moves along the curvature center line of the nickel-plated sink 32 through the mechanical constraint of the limiting ring 27, reduces the turbulence on the surface of the cable by using the vertical liquid inlet angle, makes the nickel-plated liquid uniformly adhere in a laminar flow state, and eliminates the torsional stress of the cable through the V-shaped limiting structure of the guide roller 37, and cooperates with the ceramic blade of the scraping plate 38 to realize the thickness control of the plating layer.

[0040] The actual implementation of the stirring assembly 33 is as follows: the dustproof shell 332 is made of 316L stainless steel and has a box-shaped structure, four groups of stirring rods 333 coated with polytetrafluoroethylene on the surface are welded at the bottom of the dustproof shell, the stirring rods are arranged horizontally along the width direction of the nickel-plated sink 32 and the interval is 1 / 4 of the width of the sink body; the driven wheel one 334 is fixedly connected with the top end of the stirring rod through a flat key, and the outer diameter and the interval of the stirring rod form a transmission ratio of 1:1.2; the driven wheel two 335 is a helical gear structure forged from 45# steel, is connected with the side wall of the dustproof shell through a rolling bearing, and has the bevel gear one 336 installed at the top through a spline fit, the bevel gear one and the bevel gear two 337 are a spiral bevel gear treated by carburizing of 20CrMnTi to form orthogonal meshing transmission; the connecting rod 40 is coaxially connected with the bevel gear two 337 through a flange plate, and the driven wheel three 41 arranged at the end has a module of 4 of involute gear and forms a tooth number ratio of 1:1.5 with the driving gear 143; the support frame 331 on both sides of the dustproof shell 332 is rigidly connected with the cast iron base of the workbench 31 through M12 bolts, and the distance between the bottom of the dustproof shell and the liquid surface of the nickel-plated sink is kept at an interval of 50 mm.

[0041] The driving gear 143 is driven to move clockwise by a servo motor built in the motor assembly 141. The alloy steel driving gear 143 is engaged with the helical tooth structure of the driven gear three 41 to drive the rotation of the driving gear 143, which is transmitted to the bevel gear two 337 through the connecting rod 40. The bevel gear two 337 is made of carburized 20CrMnTi alloy steel and is engaged with the bevel gear one 336 at 90° to convert the horizontal axial rotation into vertical axial rotation, thereby driving the four groups of stainless steel stirring rods 333 to stir bidirectionally in the nickel-plated submerged tank 32 at a speed of 15-20 r / min. The stirring rod 333 is welded with titanium alloy stirring blades distributed in a spiral shape at the end. Each group of stirring rods 333 is synchronously and reversely rotated through the chain wheel transmission of the driven gear one 334 and the driven gear two 335. The dustproof shell 332 is made of 6061 aluminum alloy and is internally provided with a polytetrafluoroethylene sealing ring to prevent the corrosion of the gear by plating solution vapor. The design realizes power direction conversion through the orthogonal transmission of the bevel gear set, so that the four groups of stirring rods 333 form two pairs of counter-rotating stirring units to generate staggered convection in the nickel-plated submerged tank 32, effectively breaking the stratification of the plating solution. The bolt connection structure of the dustproof shell 332 and the support frame 331 ensures that the vibration amplitude of the stirring assembly 33 is controlled within ±0.5 mm. The hard alumina alloy roller body of the limiting roller 39 maintains a distance of 50 mm from the stirring rod 333 to prevent the cable from interfering with the stirring mechanism.
