Abstract
The utility model relates to a conductive roll, which comprises a sleeve barrel and a shaft head, wherein the shaft head is arranged in the sleeve barrel; the middle part and the radial direction of the shaft head are provided with water cooling holes; an outer ring of the shaft head is provided with two webs which are matched with the inner diameter of the sleeve barrel. The utility model is characterized in that a lining sleeve is arranged between the two webs. The circumference of the lining sleeve is provided with at least one annular groove, the longitudinal direction of the lining sleeve is uniformly provided with at least one circular arc-shaped groove, and the annular groove and the circular arc-shaped groove are respectively connected with the corresponding water cooling holes on the lining sleeve. The utility model has the advantages of high structural strength, good electrical conductivity and good cooling effect.
Description
Technical field
The utility model relates to a kind of conductive rollers, relates in particular to a kind of conductive rollers of internal water cooling structure, belongs to electroplate the strip technical field.
Background technology
Conductive rollers is in electroplating the strip production process, bearing the effect that high current density send electricity, maximum can reach 45000A, not only needs to have good electrical conductivity, heating is serious under big galvanic action simultaneously, so the design of its inner cooling system also is crucial.
Up to now the conductive rollers inner cooling system of Shi Yonging has two kinds substantially:
1. as shown in Figure 1, be solid forging spindle nose conductive rollers structural shape, be to adopt solid forging spindle nose 1 hot charging to be fitted in the sleeve 2 of corrosion-resistant material, be provided with water-cooled hole 3 in the centre of solid forging spindle nose 1, though join in conjunction with having favorable conductive ability and structural strength at ends A position hot charging, cooling performance is relatively poor, this position is the heat radiation blind area, local pyrexia is serious, and particularly result of use is relatively poor under high current density.
2. as shown in Figure 2, be traditional unit-welded spindle nose conductive rollers structural shape, in order to reach cooling performance, spindle nose 4 is dwindled, the centre of spindle nose 4 and radially be provided with water-cooled hole 5, then disc 6,7 and spindle nose 4 welding after heat are assembled in the sleeve 2, though it is good at the aminoacyl site cooling conditions, the pocketed heat serious problems have been solved, but because contact area is too small between disc and the sleeve, be difficult to by high current density on the one hand, structural strength also shows slightly thin on the other hand, after long-time the use easily at the ring-like weld cracking in local two roads.
Summary of the invention
The purpose of this utility model is a kind of structural strength height of invention, conductivity is excellent and the conductive rollers of good cooling results.
For realizing above purpose, the technical solution of the utility model provides a kind of conductive rollers, comprise sleeve, spindle nose, spindle nose is located in the sleeve, in the centre of spindle nose with radially be provided with the water-cooled hole, be provided with two disc that are complementary with barrel bore in the outer ring of spindle nose, it is characterized in that, between two disc, be provided with lining.
Described lining circumference is provided with at least one cannelure, evenly is provided with at least 1 arc-shaped groove on vertically, and is connected with corresponding cooling water hole on the lining respectively.
The utility model is provided with lining between two disc, increased the weld contact area, strengthened the intensity of solid forging spindle nose, conductivity is good, utilizes the cannelure of lining circumference, vertical arc-shaped groove simultaneously again, corresponding cooling water hole, water coolant is acted directly between anti-corrosion sleeve and the lining, solved the conductive rollers heating problem, can be widely used in all kinds of plating strip production lines, particularly its advantage is more obvious under high current densities.
The utility model has the advantages that the structural strength height, conductivity is excellent and good cooling results.

Fig. 2 is traditional unit-welded spindle nose conductive rollers structural representation;
Fig. 3 is the utility model conductive rollers structural representation.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment
As shown in Figure 3, be the utility model conductive rollers structural representation, described conductive rollers is made up of sleeve 2, spindle nose 4.Spindle nose 4 is located in the sleeve 2, in the centre of spindle nose 4 with radially be provided with water-cooled hole 5, is provided with the disc 6,7 that is complementary with sleeve 2 internal diameters in the outer ring of spindle nose 4, it is characterized in that, is provided with lining 8 between disc 6,7.
Eleetrotinplate ￠ 475*1800 conductive rollers, its working condition is maximum current density 7500A/dm
2400 meters/minute of maximum unit speeds, described conductive rollers is disc 6,7 at first are welded on the spindle nose 4, carry out the precision work of disc outer ring, be processed into lining 8 inside and outside adopting roll bending welding or weldless steel tube simultaneously, lining 8 cylindricals are Φ 434mm, lining 8 width are 300mm, then lining 8 is welded to disc 6, form spindle nose 4 on 7, in order to improve the heat radiation blind area, processed a cannelure 9 on lining 8 circumference and vertically gone up 8 arc-shaped grooves 10 of uniform distribution, and be connected with corresponding cooling water hole 11 (Φ 10mm) on the lining respectively, the spindle nose 4 parts hot chargings that process have been fitted in the anti-corrosion sleeve 2 form conductive rollers.
Water coolant by the hole on the spindle nose 45 after lining 8 inner chambers are full of, flow to lining 8 outer ring cannelures 9 by 8 cooling water holes 11, enter arc-shaped groove 10 cavities in conductive rollers by cannelure 9 uniform distribution again, and flow to end in addition from 8 arc grooves 10, result of use is good.
