Description

Technical Field

[0001] The utility model relates to the technical field of electroplating equipment, in particular to an anode clamping device for electroplating a crystallizer copper tube in a flow plating manner. Background Art

[0002] The traditional electroplating method for continuous casting mold copper tubes is tank electroplating (immersion electroplating). The tubular mold and the anode are combined by fixing and connecting the support structure of the hanger, and the whole is hung in the plating tank for electroplating. Due to many defects, the fluid electroplating method has become the mainstream electroplating direction. Figure 5 The contoured anode shown is set inside the copper tube of the crystallizer, and the plating solution is passed through the gap between the anode and the workpiece by high-speed flow, and the plating solution is rapidly deposited under the action of a strong electric field. To achieve this fluid electroplating, it is necessary to set a plating solution circulation box above the copper tube of the crystallizer, so that the copper tube of the crystallizer and the plating solution circulation box form a closed plating solution chamber, and the plating solution forms a circulating fluid in this plating solution chamber through an external circulation pump. Since this electroplating method requires the contoured anode to be located inside the fluid plating solution chamber, the anode needs to be fixed inside the plating solution chamber during the electroplating process and an external power supply is required. Utility Model Content

[0003] In view of the above problems, the utility model proposes an anode clamping device for electroplating a crystallizer copper tube in a flow plating manner, which fixes the anode in a fluid plating liquid chamber and connects the anode to a power source as a conductive medium.

[0004] To achieve the above purpose, the following technical scheme is adopted: an anode clamping device for electroplating a crystallizer copper tube by flow plating, comprising a fixed sleeve, an anode clamping rod, a transmission sleeve, a sealing sleeve and an insulating sleeve,

[0005] The flange of the fixed sleeve is provided with fixing bolt holes for fixing the fixed sleeve on the plating liquid circulation box.

[0006] The anode clamping rod is installed on the fixed shaft sleeve. The two ends of the anode clamping rod are power connection terminal and clamping end respectively. The transmission thread is processed on the anode clamping rod.

[0007] The shaft hole of the transmission sleeve is sleeved on the transmission thread of the anode clamping rod, and its sleeve part is installed on the fixed sleeve through the bearing, so that the anode clamping rod produces axial displacement when the transmission sleeve rotates. The sleeve end face of the transmission sleeve is covered by an end cover plate, and a number of rotating handles are installed on the outer wall of the transmission sleeve.

[0008] The sealing sleeve is sleeved on the anode clamping rod, one end face of the sealing sleeve is embedded in the fixed shaft sleeve end face, and the other end face is used to seal with the anode clamping rod mounting hole of the plating solution circulation box, and an insulating sleeve is sleeved outside the sealing sleeve.

[0009] Furthermore, the anode clamping rod includes a conductive copper core and a titanium tube. The titanium tube is embedded outside the conductive copper core and the two are formed into one by welding. The transmission thread is located on the titanium tube. The conductive copper core is located outside the titanium tube and is divided into a power terminal. The end face of the titanium tube away from the power terminal serves as the clamping end.

[0010] Furthermore, a copper nut is embedded in the shaft hole of the transmission sleeve, and the copper nut is bolted to the transmission sleeve to form a whole, and the transmission sleeve is installed on the transmission thread of the anode clamping rod through the copper nut.

[0011] Furthermore, a first sealing ring is arranged between the anode clamping rod and the sealing sleeve, and the first sealing ring is sleeved on the anode clamping rod.

[0012] Furthermore, the sealing sleeve is made of titanium.

[0013] Furthermore, a second sealing ring is provided on the end surface of the insulating sleeve.

[0014] The utility model has the following beneficial effects: the conductive medium of the anode can be used to fix the anode in the fluid electroplating cavity, and is suitable for the fluid electroplating method of the copper tube of the crystallizer. The anode clamping rod is made of titanium-clad copper, with a copper core as the conductive medium and a titanium tube as the clamping end, which ensures both good conductivity and corrosion resistance. The transmission sleeve adopts a copper nut and an anode screw rod for transmission. Since the copper nut has self-lubricating properties, the running resistance of the transmission system is reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following is further described with reference to the accompanying drawings: Figure 1-3 To provide an anode clamping device for electroplating a crystallizer copper tube in a flow plating manner, comprising a fixed sleeve 1, an anode clamping rod 2, a transmission sleeve 3, a sealing sleeve 4 and an insulating sleeve 5, wherein:

[0023] The flange of the fixed sleeve 1 is provided with fixing bolt holes for fixing the fixed sleeve 1 on the plating solution circulation box 900.

[0024] The anode clamping rod 2 is made of titanium-clad copper, including a conductive copper core 201 and a titanium tube 202. The titanium tube 202 is embedded outside the conductive copper core 201 and the two are formed into one by welding. A transmission thread 203 is processed on the titanium tube 202. The conductive copper core 201 is located outside the titanium tube 202 and is divided into a power terminal. The end face of the titanium tube 202 away from the power terminal is used as a clamping end. A first sealing groove is processed between the transmission thread 203 and the clamping end for accommodating a first sealing ring 11.

[0025] The copper nut 6 is embedded in the shaft hole of the transmission shaft sleeve 3, and the copper nut 4 is bolted to the transmission shaft sleeve 3 so that the two are integrated.

[0026] The sealing sleeve 4 is a T-shaped sleeve made of titanium.

[0027] The two end surfaces of the insulating sleeve 5 are provided with second sealing grooves for accommodating the second sealing ring 12;

[0028] Assembly of the clamping device: the anode clamping rod 2 is installed in the axial hole of the fixed sleeve 1, the copper wire nut 6 of the transmission sleeve 3 is sleeved on the transmission thread 203 of the anode clamping rod 2 through its axial hole, and the sleeve part of the transmission sleeve 3 is installed on the fixed sleeve 1 through the bearing 7, and the bearing 7 is axially fixed on the fixed sleeve 1 through the locking nut 8. The sleeve end face of the transmission sleeve 3 is sealed by the end cover plate 9, and a number of rotating handles 10 are installed on the outer wall of the transmission sleeve 3. The sealing sleeve 4 is sleeved on the anode clamping rod 2 , and one side of the T-shaped end face of the sealing sleeve 4 is embedded in the end face of the fixed shaft sleeve 1, the first sealing ring 11 is sleeved in the first sealing groove on the anode clamping rod 2, the first sealing ring 11 is located between the anode clamping rod 2 and the sealing sleeve 4, the insulating sleeve 5 is sleeved outside the sealing sleeve 4, and the second sealing ring 12 is placed in the second sealing grooves of the two end faces of the insulating sleeve 5, one side of the end face is clamped on the T-shaped end face of the sealing sleeve, and the other side of the end face is used to be clamped on the outer wall of the anode clamping rod mounting hole of the plating solution circulation box 900.

One side end face of the sealing sleeve 4 is close to the outer wall of the anode clamping rod mounting hole of the plating solution circulation box 900, and the fixed sleeve 1 is fixed on the plating solution circulation box 900. Before power is turned on, the rotating handles 10 of the two anode clamping devices on the plating solution circulation box 900 are twisted at the same time to control the two anode clamping rods 2 to move toward the conductive copper plate of the anode located in the plating solution circulation box 900. Finally, the clamping end of the anode clamping rod 2 clamps the anode. It is necessary to ensure that the number of twisting and clamping turns on both sides is the same as much as possible to avoid crooked clamping of the anode. The first sealing ring 11 prevents the plating solution from leaking out of the gap between the titanium cylinder 202 and the sealing sleeve 4, and the second sealing ring 12 is used to prevent the plating solution from leaking out of the gap between the insulating sleeve 4 and other components.
