Description

Technical Field

[0001] This utility model relates to the technical field of continuous casting machine crystallizer processing equipment, and in particular to a fixed base for processing round tube crystallizers. Background Technology

[0002] In modern steel continuous casting production processes, the crystallizer, as the core equipment of the continuous casting machine, plays a decisive role in the quality of the continuously cast billet due to its machining accuracy. During the crystallizer machining process, firmly fixing the crystallizer on a suitable base is fundamental for performing various machining operations. However, existing crystallizer machining bases have many drawbacks, seriously affecting the machining quality and production efficiency of the crystallizer.

[0003] First, most existing crystallizer processing bases are fixed structures and lack height adjustment functionality. In actual processing, different processing steps may require the crystallizer to be at different heights. For example, during milling and drilling operations, the crystallizer height needs to be adjusted according to the tool position on the processing equipment and the operator's habits. However, fixed base structures cannot meet this requirement, making processing operations extremely inconvenient.

[0004] Secondly, the existing processing base has poor positioning effect on the crystallizer. During the processing, the crystallizer is generally positioned laterally or axially. Once the crystallizer is offset in a single direction, the subsequent processing dimensions will be deviated, resulting in a decrease in processing accuracy. This will not only increase the defect rate of the product, but may also require rework of the crystallizer, further reducing production efficiency and increasing production costs.

[0005] In summary, existing crystallizer processing bases, due to their fixed structure and poor positioning performance, cannot meet the high-precision machining requirements of modern continuous casting production. Therefore, developing a height-adjustable and stably positioned crystallizer processing base is urgently needed. This will help improve the machining quality of crystallizers, increase production efficiency, and reduce production costs, which is of great significance to the development of the steel continuous casting industry. Utility Model Content

[0006] To overcome the existing problems, this application provides a fixed base for processing a round tube crystallizer, which is adjustable in height and stably positioned to meet the height adjustment requirements during the crystallizer processing and ensure that the crystallizer maintains a stable position during processing, thereby improving processing accuracy and production efficiency.

[0007] The technical solution adopted by the embodiments of this application to solve its technical problem is: A fixed base for processing a round tube crystallizer includes a support base and a height adjustment component disposed at the top of the support base, wherein a positioning component is provided at the top of the height adjustment component; The positioning assembly includes a placement plate, which is bolted to a top plate. Two sets of axial cylinders and a transverse cylinder are provided on the top of the placement plate for clamping the workpiece. The height adjustment component includes two symmetrically arranged lifting cylinders. The bottom ends of the two lifting cylinders are fixedly connected to the support base. The output ends of the two lifting cylinders are provided with top plates. The top plates are fixedly connected to the positioning component. When the positioning component fixes the workpiece, the height adjustment component can change the vertical height of the workpiece.

[0008] Preferably, both the axial cylinder and the transverse cylinder are provided with limiting plates at their output ends. The limiting plates are arc-shaped plates, which increase the contact area when in contact with the workpiece.

[0009] Preferably, the output end of the lifting cylinder is provided with a drive shaft, the drive shaft and the top plate are detachably installed, and the lifting cylinder and the support base are connected by high-strength bolts.

[0010] Preferably, the axial cylinder and the transverse cylinder are fixed to the placement plate by bolts, and the bolt mounting holes are machined together during the manufacturing of the placement plate.

[0011] Preferably, the height adjustment assembly further includes a displacement sensor used in conjunction with the lifting cylinder to measure the extension and retraction length of the lifting cylinder.

[0012] Preferably, the axial cylinder and the transverse cylinder are selected as models with adjustable output force. According to the material and size of the crystallizer and the magnitude of the external force that may be subjected to during the processing, the working pressure of the cylinder is adjusted to provide sufficient and uniform clamping force.

[0013] The advantages of the embodiments of this application are: The positioning assembly achieves stable positioning of the crystallizer through the coordinated action of a placement plate, axial cylinders, and lateral cylinders. The placement plate provides a platform for placing the crystallizer. Two sets of axial cylinders and lateral cylinders are positioned above the placement plate. After the crystallizer is placed on the placement plate, the axial cylinders are activated, and their piston rods extend to push the limiting plate closer to the crystallizer, clamping and positioning it axially to prevent displacement during processing. Simultaneously, the lateral cylinders are activated, and their piston rods extend to clamp and position the crystallizer laterally, further enhancing the stability of the positioning. Through the coordinated action of the axial and lateral cylinders, a stable positioning frame is formed, effectively preventing the crystallizer from shifting during processing and ensuring processing accuracy.

[0014] The height adjustment component includes two symmetrically arranged lifting cylinders. The bottom of the lifting cylinders and the support base are detachably installed, which facilitates operation when maintenance or replacement is needed. By controlling the extension and retraction of the lifting cylinders, the height of the top plate can be precisely changed, thereby changing the vertical height of the crystallizer placed on the positioning component.

[0018] This application provides a fixed base for processing a round tube crystallizer, solving the problems in the prior art. The height adjustment component includes two symmetrically arranged lifting cylinders. The bottom of the lifting cylinders and the support base are detachably installed, which facilitates operation when maintenance or replacement is needed. By controlling the extension and retraction of the lifting cylinders, the height of the top plate can be accurately changed, thereby changing the vertical height of the crystallizer placed on the positioning component. By using a high-precision displacement sensor in conjunction with the lifting cylinders, the extension and retraction length of the lifting cylinders can be accurately measured, meeting the requirements of high-precision processing.

[0019] The technical solution in this application is to solve the above problems, and the overall approach is as follows: Example This embodiment provides a specific structure for a fixed base in the processing of a circular tube crystallizer, such as... Figure 1-5As shown, it includes a support base 1 and a height adjustment component 3 disposed at the top of the support base 1, and a positioning component 2 is provided at the top of the height adjustment component 3; Positioning component 2 includes a placement plate 21, and two sets of axial cylinders 22 and transverse cylinders 24 are provided on the top of the placement plate 21 for clamping the workpiece. The height adjustment component 3 includes two symmetrically arranged lifting cylinders 32. The bottom ends of the two lifting cylinders 32 are fixedly connected to the support base 1. The output ends of the two lifting cylinders 32 are provided with top plates 31. The output ends of the lifting cylinders 32 are provided with drive shafts 33, which are connected to the top plates 31. The top plates 31 are connected to the placement plate 21 inside the positioning component 2 by bolts. When the positioning component 2 fixes the workpiece, the height adjustment component 3 can change the vertical height of the workpiece.

[0020] Furthermore, after the crystallizer is placed on the placement plate 21, the axial cylinder 22 is activated. The piston rod of the axial cylinder 22 extends and pushes the limiting plate 23 closer to the crystallizer, clamping and positioning the crystallizer in the axial direction to prevent displacement of the crystallizer along the axial direction during processing. At the same time, the transverse cylinder 24 is activated. The piston rod of the transverse cylinder 24 extends and clamps and positions the crystallizer in the transverse direction, further enhancing the stability of the positioning. Through the synergistic effect of the axial and transverse cylinders, a stable positioning frame is formed, effectively preventing the crystallizer from shifting during processing and ensuring processing accuracy.

[0021] Axial cylinder 22 and transverse cylinder 24 are fixed to the placement plate 21 by bolts. The bolt mounting holes are machined together during the manufacturing of the placement plate 21. The output ends of both axial cylinder 22 and transverse cylinder 24 are provided with limiting plates 23. The limiting plates 23 are arc-shaped plates to increase the contact area when in contact with the workpiece. The axial cylinder 22 and transverse cylinder 24 are selected as models with adjustable output force. According to the material and size of the crystallizer and the magnitude of the external force that may be subjected to during the processing, the working pressure of the cylinder is adjusted to provide sufficient and uniform clamping force.

[0022] Next, place the round tube crystallizer on the placement plate 21, ensuring that the center of the crystallizer is aligned with the center of the placement plate 21. Start the axial cylinder 22, and by adjusting the working pressure of the cylinder, extend the piston rod of the axial cylinder 22 at a suitable speed, pushing the limiting plate 23 closer to the crystallizer. After the limiting plate 23 contacts the outer wall of the crystallizer, continue to apply a certain pressure, so that the limiting plate 23 generates an axial clamping force on the crystallizer. At the same time, start the transverse cylinder 24, and extend the piston rod of the transverse cylinder 24 to clamp the crystallizer from the transverse direction. During the clamping process, observe whether the position of the crystallizer has shifted. If there is a shift, fine-tune the clamping force of the cylinder to make the crystallizer in the correct position. By adjusting the clamping forces of the axial cylinder 22 and the transverse cylinder 24, ensure that the crystallizer is stably positioned in both the axial and transverse directions to meet the processing accuracy requirements.

[0023] The output end of the lifting cylinder 32 is equipped with a drive shaft 33, which is detachably installed with the top plate 31. A bolt is screwed into the top plate 31, and a threaded hole matching the bolt is opened at the intersection of the drive shaft 33 and the top plate 31. In this way, the drive shaft 33 and the top plate 31 can be detached and installed by bolts. The lifting cylinder 32 is connected to the support base 1 by high-strength bolts. When installing the lifting cylinder 32, the bottom end of the lifting cylinder 32 is connected to the support base 1 by bolts, and the bolt tightening torque is operated according to the specified value.

[0024] The placement plate 21 is connected to the top plate 31 by bolts. Both ends of the top plate 31 are provided with threaded holes. When connecting the top plate 31 and the placement plate 21, the bolts are removed and screwed into the threaded holes at both ends of the top plate 31, and then screwed onto the placement plate 21.

[0025] The height adjustment assembly 3 also includes a displacement sensor 34 used in conjunction with the lifting cylinder 32 to accurately measure the extension and retraction length of the lifting cylinder 32. The displacement sensor 34 measures displacement by utilizing the change in the distance between the capacitor plates. When an object moves closer to or away from the capacitor, the capacitance value of the capacitor changes accordingly. By measuring the change in capacitance value, the displacement information of the object can be obtained.

[0026] Furthermore, before crystallizing, the required height of the crystallizer is determined according to the processing requirements and the parameters of the processing equipment. By operating the control button of the lifting cylinder 32 or the automatic control system, a command is sent to the lifting cylinder 32 to control its extension and retraction. If it is necessary to raise the crystallizer, the piston rod of the lifting cylinder 32 is extended; if it is necessary to lower the crystallizer height, the piston rod is retracted. During the lifting and lowering process, the displacement sensor 34 monitors the extension and retraction length of the lifting cylinder 32 in real time and feeds the data back to the control system. When the preset height position is reached, the control system stops the action of the lifting cylinder 32. The operator can view the current height value of the crystallizer through the display screen on the control panel to ensure that the height adjustment is accurate.

[0027] Finally, all cylinders in this application are connected to external pressure pipes to provide power to the cylinders.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
