Description

Technical Field

[0001] The utility model relates to the technical field of crystallizers, in particular to a clamping tool for remanufacturing a plate-type crystallizer. Background Art

[0002] The crystallizer is the core component of continuous casting. The crystallizer copper plate is an important heat-conducting component for continuous casting from liquid molten steel to solidified solid billet shell. Its quality directly affects the surface quality of the billet, the casting speed of the continuous casting machine and other indicators. The molten steel flows through the crystallizer copper plate, crystallizes into billets under the action of external cooling water, and is pulled out of the crystallizer by the dummy rod. Frequent billet pulling causes serious wear of the crystallizer copper plate, which needs to be replaced frequently. Therefore, a layer of metal or alloy is usually electroplated on the crystallizer copper plate to achieve the purpose of anti-wear and wear reduction and extend the service life. The commonly used electroplating methods are full electroplating and partial electroplating processes. When performing partial electroplating, the non-electroplated surface must be shielded and protected.

[0003] The utility model patent with application number CN202120424564.3 (hereinafter referred to as prior art 1) discloses a non-electroplating surface protection device for nickel-cobalt plating of a crystallizer copper plate, which relates to the field of electroplating technology of a crystallizer copper plate. A silicone pad is fixedly installed on the top of the protective plate, and a copper plate body is movably installed on the top of the silicone pad. Limit bearings are fixedly installed on both sides of the protective plate, and clamping screws are movably installed inside the limit bearings, and movable seats are movably connected to the outside of the clamping screws. The non-electroplating surface protection device for nickel-cobalt plating of a crystallizer copper plate is composed of a fixed structure formed by setting a top plate, a fixed screw sleeve, a fixed screw, a fixed handle, a fixed plate and a fixed pad, and the copper plate body is fixedly protected in conjunction with the protective plate and the silicone pad. The setting of the silicone pad increases the sealing between the protective plate and the copper plate body, prevents the plating solution from easily leaking along the fitting surface, causing residual plating solution on the non-electroplating surface, improves the protection effect on the copper plate body, and improves the quality of electroplating.

[0004] However, the prior art 1 adopts a pressing method to fix the copper plate. When the fixing plate set on the fixing screw fixes the copper plate, the fixing plate is in close contact with the copper plate, resulting in that the pressing part of the fixing plate cannot contact the electroplating solution, and electroplating cannot be achieved, resulting in major defects in the electroplating remanufacturing of the copper plate. Utility Model Content

[0005] The purpose of the utility model is to provide a plate-type crystallizer remanufacturing clamping tool, which in actual use can solve the technical problem that the prior art uses a press-fitting method to fix the copper plate for electroplating, resulting in the pressed part of the copper plate being unable to be electroplated, causing defects in the copper plate.

The upper surface of the base 101 is flush with the upper surface of the support frame 102, and a sealing gasket 110 is arranged on the upper surface of the base 101 and the upper surface of the support frame 102.

[0039] In this embodiment, after the crystallizer copper plate 105 is negatively adsorbed by the suction cup 106, the non-electroplated surface of the copper plate 105 is brought into contact with the sealing gasket 110 and squeezed against each other under the action of the driving mechanism 109, thereby fixing the crystallizer copper plate 105; the support frame 102 can support the copper plate 105, so that the force on the copper plate 105 is more uniform. When in use, the utility model can expose the surface to be electroplated in all directions, clamp the crystallizer copper plate 105 and fix it by negative pressure, and then send the tooling as a whole to the electroplating pool for remanufacturing. The utility model solves the technical problem that the prior art uses a press-fitting method to fix the copper plate 105 for electroplating, which causes the pressed part of the copper plate 105 to be unable to be electroplated, resulting in defects in the copper plate 105, and can ensure the remanufacturing quality of the crystallizer copper plate 105.

Under the action of the negative pressure device, the suction cup 106 is sucked. At this time, after the air inside the suction cup 106 is sucked away, the suction cup 106 will move toward the copper plate 105 and contact the copper plate 105 and stick together; at this time, the telescopic rod 114 moves, driving the suction cup 106 to move downward, so that the copper plate 105 can be pulled so that the copper plate 105 is attached to the sealing pad 110, thereby achieving coverage and shielding of the non-electroplated surface.

[0048] Furthermore, a buffer pad 118 is provided on a surface of the connector 115 that contacts the limiting portion 121 , so as to provide a buffer during contact.
