Description

Technical Field

[0001] This utility model relates to the field of chromium plating technology for rectangular crystallizer copper tubes, specifically to an external clamping fixture for chromium plating of rectangular crystallizer copper tubes. Background Technology

[0002] The copper tube of the crystallizer is a key component of the continuous casting machine, which is in direct contact with high-temperature molten steel and operates under harsh conditions. To improve its wear resistance, corrosion resistance and service life, a hard chrome plating layer is usually applied to its inner surface, and an external clamping fixture is required when facing the hard chrome plating layer.

[0003] In existing technology, when fixing copper tubes, bolts are placed between two pressure plates. The pressure plates are then moved synchronously by pulling the bolts, thus fixing the copper tube between the pressure plates. Subsequently, conductive plates on both sides are pressed tightly against the sides of the copper tube to prevent the copper tube from moving during the chromium plating process. However, in actual use, this device requires constantly tightening the bolts on both sides to fix the copper tube. As a result, the need for constant tightening during the adjustment and fixing process leads to a longer fixing time, which is inconvenient for the rapid fixing of copper tubes and further increases the time required before the copper tube is fixed. Therefore, there is a need to improve the rectangular crystallizer copper tube chromium plating external clamping fixture. Utility Model Content

[0004] The purpose of this invention is to provide a chrome-plated external clamping fixture for rectangular crystallizer copper tubes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rectangular crystallizer copper tube chrome-plated external clamping fixture, including a fixing plate, an adjusting frame fixedly connected to the top of the fixing plate, a fixing and pressing mechanism provided outside the adjusting frame, a conductive mechanism provided outside the fixing and pressing mechanism, and a copper tube provided outside the fixing and pressing mechanism;

[0006] The fixing and clamping mechanism includes a fixing component and a clamping component, wherein the clamping component is disposed at the bottom of the fixing component;

[0007] The fixing component includes a pressure plate, which is slidably connected to the outside of the adjusting frame. A rotating block is rotatably connected to the top of the pressure plate, and a retaining frame is fixedly connected to the bottom of the rotating block. A connecting column is movably connected to the inside of the retaining frame, and a push block is fixedly connected to the bottom of the connecting column. A spring is fixedly connected between the push block and the pressure plate to facilitate adjustment of the appropriate fixing position according to different specifications of copper tubes.

[0008] Preferably, the front of the adjustment frame has multiple through slots, and the push block is inserted into the slots to facilitate adjustment of the pressure plate position.

[0009] Preferably, the push block is slidably connected inside the pressure plate, and the pressure plate has a hole at the corresponding position of the card frame, and the card frame is rotatably connected in the hole to facilitate fixing the position of the pressure plate.

[0010] Preferably, the clamping assembly includes a connecting seat, which is fixedly connected to the top of the fixing plate and the bottom of the pressure plate respectively. A sliding column is slidably connected inside the connecting seat, and a rubber block is fixedly connected to the outside of the sliding column. A bolt is threaded between the rubber block and the connecting seat to facilitate fixing the copper tube between the rubber blocks.

[0011] Preferably, the connecting seat has a hole at the corresponding position of the sliding column, and the sliding column is slidably connected in the hole, and the copper tube is pressed between the rubber blocks, which facilitates easy disassembly and replacement of the rubber blocks.

[0012] Preferably, the conductive mechanism includes a connecting sleeve, which is slidably connected to the inner side of the pressure plate. A pull plate is slidably connected inside the connecting sleeve. A spring is fixedly connected between the pull plate and the connecting sleeve. Conductive sheets are fixedly connected to the front and rear inner sides of the connecting sleeve. A hook is fixedly connected to the top of the conductive sheet to facilitate the conductive sheets on both sides to be tightly attached to the outer wall of the copper tube.

[0013] Preferably, the pressure plate has multiple through slots inside, and the pull plate is inserted into the slots to facilitate adjustment and fixation of the conductive sheet position.

[0014] Compared with the prior art, this utility model provides a chrome-plated external clamping fixture for rectangular crystallizer copper tubes, which has the following advantages:

[0015] 1. The rectangular crystallizer copper tube chrome-plated external clamping fixture, through the set fixed clamping mechanism, places the corresponding copper tube between the upper and lower rubber blocks. By manually rotating the rotating block, the push block is disengaged from the corresponding slot of the adjustment frame. Then, the pressure plate is pulled up or down to fix the copper tube between the rubber blocks, forming a bottom connection. Then, the rotating block is released, and under the elastic force of the spring, the push block is reinserted into the corresponding slot of the adjustment frame, thus quickly completing the fixation of the copper tube. The fixation process does not require repeated twisting, thereby reducing the time required to fix the copper tube.

[0016] 2. The rectangular crystallizer copper tube chrome plating external clamping fixture, through the set conductive mechanism, allows manual pulling of the pull plate to completely detach it from the pressure plate. Then, the connecting sleeve is pushed or pulled to the left or right, thus pressing its conductive sheet tightly against the surface of the copper tube. At this time, the pull plate is released, and under the elastic force of the second spring, the pull plate is reinserted into the corresponding groove of the pressure plate. This allows the device to quickly complete the adjustment of the guide plate, facilitating the subsequent chrome plating work. Attached Figure Description

[0032] Furthermore, holes are provided at the corresponding positions of the connecting seat 321 and the sliding column 322, and the sliding column 322 is slidably connected in the holes, and the copper tube 5 is pressed between the rubber blocks 323, which facilitates the easy disassembly and replacement of the rubber blocks 323. Example

[0033] Based on the existing technology, there is a problem with adjusting the position of the conductive sheet 44. Please refer to [link / reference]. Figure 5 Furthermore, in conjunction with Embodiment 1, it is further obtained that the conductive mechanism 4 includes a connecting sleeve 41, which is slidably connected to the inner side of the pressure plate 311. A pull plate 42 is slidably connected inside the connecting sleeve 41. A spring 43 is fixedly connected between the pull plate 42 and the connecting sleeve 41.

At this time, the pull plate 42 is released, and under the elastic force of the second spring 43, the pull plate 42 is reinserted into the corresponding slot of the pressure plate 311, so that the device can quickly complete the adjustment of the key plate, making it convenient for the subsequent chrome plating work.
