Description

Technical Field

[0001] The utility model relates to the technical field of high-speed wire production, in particular to a high-speed wire correction rolling line tool. Background Art

[0002] In the high-speed wire production process of Anshan Iron and Steel Wire Plant, the roughing and intermediate rolling mill plays a vital role. The production line is equipped with 13 roughing and intermediate rolling mills, of which the 6th to 13th are specially designed with a two-base guide beam structure that can be adjusted laterally. The main purpose of this design is to quickly and accurately adjust the position of the inlet and outlet guides when the rollers are grooving, so that they are aligned with the rolling groove, thereby ensuring the stability and accuracy of the wire during rolling;

[0003] However, in the actual production process, these adjustable guide beams face a serious problem: since the roller cooling water needs to be sprayed on the rollers and guide beams for a long time and uninterruptedly to ensure the normal operation of the rollers and extend their service life, this continuous water vapor erosion causes serious rust on the guide beam adjustment device. The rust not only weakens the mechanical properties of the adjustment device, but also increases the friction resistance during adjustment, making it often impossible for the guide beam to move smoothly and accurately when it needs to be adjusted, seriously affecting the continuity of production and the quality of the wire. In order to solve this problem, the factory usually needs to replace the guide beam affected by rust. However, the replacement process of the guide beam is not easy. First of all, due to the precise and complex installation position of the guide beam, the installation elevation needs to be precisely controlled during replacement to ensure that the new guide beam can be accurately aligned with the rolling groove. However, in actual operation, due to the limitations of the on-site environment and the limitations of the measuring tools, it is often difficult to achieve such high-precision alignment requirements, resulting in low installation efficiency and even subsequent production problems due to inaccurate alignment. What is more serious is that if the inaccurate alignment problem is not discovered when the new guide beam is installed and corrected, once the production line is started, the wire may be subjected to uneven force during the rolling process due to the slight deviation between the rolling line and the guide beam, resulting in a steel pile accident. The steel pile accident will not only cause waste of wire and shutdown of the production line, but may also cause damage to the rolling mill and related equipment, bringing serious economic losses and safety risks to the factory. Therefore, we proposed a high-speed wire correction rolling line tool to solve the above problems. Utility Model Content

[0026] In some embodiments, a mounting groove 11 is formed on the mounting block 9 , and two T-shaped rods 12 are welded on the top of the mounting block 9 .

[0027] In some embodiments, a connecting block 13 is slidably connected to the T-shaped rod 12, and a spring 14 is welded between one side of the connecting block 13 and the top inner wall of the corresponding T-shaped rod 12. The spring 14 is movably mounted on the corresponding T-shaped rod 12, and the setting of the spring 14 plays a resetting role.

[0028] In some embodiments, the same moving block 15 is fixedly connected between the two connecting blocks 13 , and two bayonet pins 16 are welded to the bottom of the moving block 15 . The provision of the bayonet pins 16 plays a fixing role.

[0029] In some embodiments, two slots 18 are provided on the top of the gauge rod 10 , and the slots 18 are engaged with corresponding latches 16 , and a pull ring 17 is welded on the top of the moving block 15 .

[0030] In some embodiments, a limit groove 19 with an open side is provided on the inner walls on both sides of the installation groove 11, and a limit rod 20 is clamped on the limit groove 19. One side of the limit rod 20 is fixedly connected to one side of the gauge rod 10. The setting of the limit rod 20 plays a positioning role.

[0031] Working principle or structural principle, when in use, the tool is first accurately docked with the guide beam 1 through its first base 4. The design of the first base 4 enables it to be fixed on the positioning key 3 of the guide beam 1, and the front end can completely fit on the dovetail groove 2 of the guide beam 1. This design ensures the stability and positioning accuracy of the first base 4 on the guide beam 1, so that it can be integrated with the various limit devices of the guide beam 1. An upright vernier caliper 7 is installed directly above the second base 6. The selection of the vernier caliper 7 has sufficient accuracy and length (1 meter) to meet the correction requirements. On the movable measuring claw 8 of the vernier caliper 7, a one-meter-long and detachable gauge rod 10 is installed. The gauge rod 10 is placed horizontally at 90° with the vernier caliper, so that it can pass through the hole type of the guide beam 1 that needs to be corrected. The design of the gauge rod 10 enables it to smoothly pass through the roller hole type and be in the center of the hole type. This The first step is the key in the calibration process. It ensures that the gauge rod 10 can accurately reflect the actual height of the guide beam. When the gauge rod 10 is at the center of the roller hole, read the value on the vernier caliper 7. This value represents the difference between the actual height of the guide beam 1 and the correct installation elevation. According to the read value, a gasket of appropriate height can be added or reduced at the bottom of the guide beam 1 to adjust the actual height of the guide beam 1 so that it reaches the correct installation elevation. This not only saves time and labor costs, but also reduces the cost of required spare parts, and realizes precise control of the installation elevation of the guide beam 1. When the gauge rod 10 needs to be removed, pull the pull ring 17, the pull ring 17 drives the moving block 15 to move, the moving block 15 drives the connecting block 13 to slide on the corresponding T-bar 12 and compress the spring 14, and the moving block 15 drives the latch 16 to separate from the corresponding slot 18, and the gauge rod 10 is moved to be removed.
