Description

Technical Field

[0001] This utility model belongs to the field of crystallizer chromium plating technology, specifically relating to a chromium plating fixture for crystallizers. Background Technology

[0002] After the copper tubes of the crystallizer are manufactured, they are chrome-plated on the inner wall of the crystallizer. The copper tubes of the continuous casting crystallizer are prone to corrosion under high temperature and high pressure. The plating can effectively prevent corrosion and extend the service life.

[0003] Currently, chrome plating fixtures typically use an assembly-type hanger before use. This hanger consists of upper and lower support plates. The upper support plate is fastened to the copper tube of the crystallizer from both sides (i.e., two U-shaped clamps form a support plate). After the copper tube is aligned, the upper support plate is assembled and fixed. After the anode of the chrome plating fixture is placed into the copper tube, the corresponding bolt positions need to be adjusted by rotating and adjusting the anode to ensure that it is in the exact center of the copper tube. This ensures that the distance between the outer side and the inner walls of the copper tube is consistent, which is essential for uniform plating. However, the alignment operation of the copper tube of the crystallizer inside the hanger and the anode inside the copper tube of the crystallizer affects work efficiency and cannot guarantee adjustment accuracy. Summary of the Invention

[0004] This invention addresses the problem that existing chrome plating fixtures, when used, require alignment of the copper tube in the crystallizer within the fixture and the anode within the copper tube in the crystallizer. This alignment affects work efficiency and compromises adjustment accuracy. The invention provides a chrome plating fixture for crystallizers that directly aligns and limits the copper tube during installation via copper tube limiting grooves on the upper and lower clamps. The anode limiting groove and limiting block position and limit the lower end of the anode tube. Furthermore, the upper part of the anode tube is aligned and limited by passing its upper end through the anode limiting hole. Therefore, no further adjustment is needed after installation, directly achieving the alignment and limiting effect of the copper tube.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows: A chrome-plating fixture for a crystallizer includes an upper clamping plate and a lower clamping plate arranged opposite each other. The upper and lower clamping plates are connected by multiple screws. A copper tube is disposed between the upper and lower clamping plates, and an anode tube is sleeved inside the copper tube. There is a gap between the inner wall of the copper tube and the outer wall of the corresponding anode tube. Copper tube limiting grooves are formed on opposite sides of the upper and lower clamping plates, and the ends of the copper tubes are located in the corresponding copper tube limiting grooves. An anode limiting groove is formed on the bottom surface of the copper tube limiting groove on the lower clamping plate. The copper tube limiting groove on the upper clamping plate... A positive limit hole is provided on the inner bottom surface, which matches the outer side of the upper end of the anode tube. A limit block is fixedly installed in the middle of the inner bottom surface of the positive limit groove. The limit block has a conical structure that is smaller at the top and larger at the bottom, and the lower part of the limit block matches the inner side of the lower end of the anode tube. After the upper end of the anode tube extends out of the positive limit hole, a conductive plate is fixedly connected. The copper tube is limited by the cooperation of two copper tube limit grooves. The lower end of the anode tube is positioned and limited by the limit block and the positive limit groove. The upper part of the anode tube is limited by the positive limit hole of the copper tube.

[0006] Preferably, the upper and lower clamping plates are respectively provided with multiple connecting holes, and a limit rod is provided on the side of the upper and lower clamping plates that is far apart from each other. The lead screw passes through the corresponding connecting hole and is threaded to the corresponding limit rod. The limit rod fixes both ends of the lead screw to ensure the stability of the upper and lower clamping plates after installation.

[0007] Preferably, there are four lead screws, eight connecting holes, and four limiting rods, with each limiting rod threaded to the ends of two adjacent lead screws.

[0008] Preferably, multiple conductive plates are provided, and each conductive plate is fixedly connected to the outer side of the end of the anode tube extending out of the copper tube. The contact surface is increased by the overlap between the lower part of the conductive plate and the upper part of the anode tube to ensure the conductivity effect.

[0009] Preferably, both the upper and lower plates are provided with through holes, which connect the inside and outside of the copper tube. The through holes are located on the outside of the anode tube to ensure that the plating solution enters the copper tube and is plated when the anode tube is energized.

[0010] The beneficial effects of this utility model through the above technical solution are as follows: 1. This utility model achieves two-phase conductivity by setting a hollow tubular anode and utilizing the hollow characteristics of the anode tube, thereby improving current utilization and stabilizing product quality.

[0011] 2. This utility model achieves the positioning of copper tubes during installation through copper tube limiting grooves on the upper and lower clamping plates, and limits the copper tubes through the lead screw in conjunction with the copper tube limiting grooves. The limiting block achieves the guiding positioning of the anode tube during installation, and further limits both ends of the anode tube in conjunction with the anode limiting groove and anode limiting hole. Thus, the copper tube and anode tube can be directly aligned and limited during installation. The structure is simple and the installation is convenient.

[0012] 3. This utility model uses a hollow tubular anode made of aluminum-tin-antimony alloy, which, compared to the existing structure with steel support inside the hollow aluminum-tin-antimony alloy, avoids the difference in conductivity between the inside and outside. This avoids the problem of the outer hollow structure being overheated and melted due to poor conductivity, and the iron ions generated by the dissolution of the internal steel entering the plating solution, shortening the service life of the plating solution, increasing the difficulty of environmental treatment of grass leaves, and making the repair of the melted and damaged anode difficult. Furthermore, the repaired anode will affect the quality of the coating when reused. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments: like Figures 1-10 As shown, this embodiment provides a chrome-plating fixture for a crystallizer, including an upper clamping plate 1 and a lower clamping plate 2 arranged opposite each other. Both the upper clamping plate 1 and the lower clamping plate 2 are made of PVC board and are connected by multiple screw rods 3. A copper tube 4 is provided between the upper clamping plate 1 and the lower clamping plate 2. Multiple connecting holes 11 are respectively opened on the upper clamping plate 1 and the lower clamping plate 2. A limit rod 12 is provided on the side of the upper clamping plate 1 and the lower clamping plate 2 that is far away from each other. The screw rod 3 passes through the corresponding connecting hole 11 and is threaded to the corresponding limit rod 12. By rotating the screw rod 3, the upper clamping plate 1 and the lower clamping plate 2 are moved closer or further apart, thereby fixing and limiting the copper tube 4. There are four screw rods 3, eight connecting holes 11, and four limit rods 12. Each limit rod 12 is threaded to the ends of two adjacent screw rods 3. Both the screw rods 3 and the limit rods 12 are plastic-coated steel rods.

[0025] An anode tube 5 is fitted inside the copper tube 4. A gap exists between the inner wall of the copper tube 4 and the corresponding outer wall of the anode tube 5. Specifically, the distance between the outer wall of the anode tube 5 and the inner wall of the copper tube 4 is equal, forming a chromium-plating space. Copper tube limiting grooves 6 are provided on opposite sides of the upper clamping plate 1 and the lower clamping plate 2. The end of the copper tube 4 is located within the corresponding copper tube limiting groove 6. During installation, first, the lower end of the copper tube 4 is placed in the copper tube limiting groove 6 on the lower clamping plate 2, then the upper clamping plate 1 is installed. By rotating the screw 3, the upper end of the copper tube 4 is positioned within the copper tube limiting groove 6 on the upper clamping plate 1. An anode limiting groove 7 is provided on the bottom surface of the copper tube limiting groove 6 on the lower clamping plate 2, and an anode limiting hole 8 is provided on the bottom surface of the copper tube limiting groove 6 on the upper clamping plate 1. The anode... The limiting hole 8 matches the outer side of the upper end of the anode tube 5. A limiting block 9 is fixedly installed in the middle of the bottom surface of the anode limiting groove 7. The limiting block 9 has a tapered structure that is smaller at the top and larger at the bottom, and the lower part of the limiting block 9 matches the inner side of the lower end of the anode tube 5. The lower end of the anode tube 5 is passed through the anode limiting hole 8 and guided and positioned by the limiting block 9. Then, the lower part of the anode tube 5 is located in the anode limiting groove 7. The anode limiting groove 7 and the limiting block 9 limit the lower part of the anode tube 5. At this time, the upper end of the anode tube 5 extends out of the anode limiting hole 8. The anode limiting hole 8 limits the upper part of the anode tube 5, directly making the distance between the outer wall of the anode tube 5 and the inner wall of the copper tube 4 equal, forming a chromium plating space. No adjustment is required by bolts, which improves the assembly efficiency.

[0026] As one possible implementation, the anode tube 5 and the copper tube 4 are square tubes.

[0027] In one possible implementation, the anode tube 5 and the copper tube 4 are curved arc-shaped tubes.

[0028] The upper end of the anode tube 5 extends out of the anode limit hole 8 and is then fixedly connected to a conductive plate 10. Multiple conductive plates 10 are provided, and each conductive plate 10 is fixedly connected to the outer side of the end of the anode tube 5 extending out of the copper tube 4. By making the conductive plate 10 contact the side of the anode tube 5, rather than directly fixing it to the end of the anode tube 5, the contact area between the conductive plate 10 and the anode tube 5 can be effectively increased, ensuring the conductivity effect. The conductive plate 10 is a copper plate, and its lower part needs to be coated with plastic.

[0029] Both the upper plate 1 and the lower plate 2 are provided with through holes 13. The through holes 13 connect the inside and outside of the copper tube 4. The through holes 13 are located on the outside of the anode tube 5. By setting the through holes 13, it is ensured that the plating solution can smoothly enter the inside of the copper tube 4 and contact the inner wall of the copper tube 4 during the chromium plating process, thereby ensuring the smooth progress of chromium plating.

[0030] In use, first, place the lower end of the copper tube 4 into the copper tube limiting groove 6 on the lower clamping plate 2, then install the upper clamping plate 1 so that the upper part of the copper tube 4 is located in the copper tube limiting groove 6 of the upper clamping plate 1. Then rotate the screw 3 so that the limiting rod 12 clamps and fixes the upper clamping plate 1 and the lower clamping plate 2. Then, pass the lower end of the anode tube 5 through the anode limit hole 8 and use the limiting block 9 for guidance and positioning. Then, the lower part of the anode tube 5 is located in the anode limit groove 7. The anode limit groove 7 and the limiting block 9 limit the lower part of the anode tube 5. At this time, the upper end of the anode tube 5 extends out of the anode limit hole 8, and the anode limit hole 8 limits the upper part of the anode tube 5. At the same time, the through hole 13 ensures that the plating solution can smoothly enter the interior of the copper tube 4 and contact the inner wall of the copper tube 4 during the chromium plating process, thereby ensuring the smooth progress of chromium plating.

Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
