Description

Technical Field

[0001] The utility model mainly relates to the technical field of chromium plating for mold copper tubes, and particularly relates to a fixture for automatically positioning an anode for chromium plating on the inner wall of a new type of mold copper tube. Background Art

[0002] After the copper tube of the mold is manufactured, chromium plating operation is carried out on the inner wall of the mold. The copper tube of the continuous casting mold is prone to corrosion under high temperature and high pressure conditions. The coating can effectively prevent corrosion and extend the service life.

[0003] The traditional chromium plating method is to immerse the copper tube in a chromium plating tank for immersion chromium plating. This chromium plating method has large pollution, high cost and high energy consumption. Therefore, some enterprises have begun to adopt out-of-tank chromium plating. Its main principle is to set a cathode block tube inside the mold, and a chromium plating space is formed between the wall of the cathode block tube and the inner wall of the mold copper tube. The mold and the cathode block tube are placed on a fixture, and the mold copper tube and the cathode block are sealed. The chromium plating solution will be transported upward through the bottom of the fixture, pass through the chromium plating space, and be energized with the anode to complete the chromium plating operation.

[0004] That is to say, this chromium plating method requires a suitable fixture to seal and position the mold copper tube and the cathode block.

[0005] The inventor found the following defects in the specific embodiment operation process:

[0006] At present, when using the existing chromium plating fixture, in order to ensure that the cathode block is in the middle of the mold copper tube, that is, the distance between the outer wall of the cathode block and the four sides of the inner wall of the mold is the same, bolts are required to assemble and position the cathode block and the fixture, and then determine its assembly position. This method is inaccurate and inefficient, and the lengths of the bolts on the four sides need to be adjusted repeatedly.

[0007] It should be noted that the above content belongs to the technical cognition scope of the inventor. Due to the vast and complex technical content in this field, the above content of this application does not necessarily constitute the prior art. Content of the Utility Model

[0008] 1. Technical problems to be solved by the utility model:

[0009] The utility model provides a fixture for automatically positioning an anode for chromium plating on the inner wall of a new type of mold copper tube to solve the technical problems existing in the above background art.

[0010] 2. Technical solution:

[0011] To achieve the above object, the technical solution provided by the present utility model is: a fixture for automatically positioning an anode with chromium plating on the inner wall of a new type of mold copper tube, including a lower fixture. The lower fixture includes a support plate. A plurality of sealing grooves are provided at the bottom of the support plate. A cathode insertion groove is formed in the middle of the support plate. Overflow grooves are provided on four sides of the cathode insertion groove. A copper tube positioning groove is provided outside the overflow groove. It further includes an upper fixture. The upper fixture is symmetrically arranged with the lower fixture in a mirror image. When the device works, it needs to be used in cooperation with the existing out-of-tank chromium plating equipment. The out-of-tank chromium plating equipment is an existing technology and will not be elaborated here. Place the lower fixture on the liquid outlet plate of the out-of-tank chromium plating equipment. Then insert the cathode block into the bottom cathode insertion groove. Insert the mold copper tube to be chromium plated into the copper tube positioning groove. Connect the upper fixture to the top of the mold copper tube in the same way, and the installation operation of the fixture can be completed. Since the cathode insertion groove and the copper tube positioning groove are provided on the upper fixture and the lower fixture, it can ensure that the distance between the outer wall of the cathode block and the inner wall of the mold is the same, forming a chromium plating space, without the need to adjust by bolts, improving the work efficiency of assembly. During work, the chromium plating solution moves upward from the chromium plating space and then flows back into the tank through the overflow groove of the upper fixture, and the chromium plating operation can be completed.

[0012] Further, leak-proof grooves are also provided outside the copper tube insertion grooves of the upper fixture and the lower fixture, and sealing rubber rings are inserted into the leak-proof grooves.

[0013] Further, the support plate includes a circular support block or a square support block.

[0014] Further, connection holes are formed in the support plates of the upper fixture and the lower fixture, and the connection holes are matched with locking screws for connection.

[0015] Further, four connection holes are provided, and they are arranged in a cross on the support plate.

[0016] Further, the overflow groove includes symmetrically arranged L-shaped through grooves, and the L-shaped through grooves are arranged in a rectangle.

[0017] Further, the outer diameter of the cathode block is smaller than the rectangular space formed by the L-shaped through grooves.

[0018] 3. Beneficial effects:

[0019] Adopting the technical solution provided by the present utility model, compared with the prior art, it has the following beneficial effects:

[0020] The present utility model is reasonably designed. This device is suitable for out-of-tank chromium plating operations. When in use, the corresponding cathode and the mold copper tube can be directly inserted into the corresponding card slots of the two fixtures, which can ensure that the chromium plating solution can flow in the chromium plating space, and the chromium plating operation can be carried out during the flowing process. The entire assembly process has high efficiency and does not require repeated distance debugging of the cathode and the mold.

[0021] By setting the sealing rubber ring and the locking screw, the upper and lower hangers can be hermetically clamped to ensure the safe progress of the chrome plating operation.

[0022] It should be noted that the structures not introduced in the present utility model are the same as the prior art or can be implemented by the prior art because they do not involve the design key points and improvement directions of the present utility model, and will not be elaborated here.
