Description

Technical Field

[0001] The utility model relates to the technical field of steel strip and steel coil production, and specifically to a roll set device of a tension leveling descaling machine. Background Art

[0002] The main functions of a tension leveling descaling machine are to eliminate the stress generated during the rolling process of a steel coil or steel strip (referred to as "straightening"), and at the same time remove the oxide scale and phosphating layer on the surface of the steel coil or steel strip (referred to as "descaling"), so as to improve the surface quality and mechanical properties of the steel.

[0003] At present, the rollers on the tension leveling descaling machine are in direct contact with the steel coil or steel strip, and different rollers are used to apply tension or compressive force to the steel coil or steel strip to eliminate its internal stress and remove the oxide scale and phosphating layer on the surface of the steel coil or steel strip. However, there is a problem of insufficient stability in the connection between the rollers and the frame. If elastic rollers are used, by pressing the elastic rod to retract it into the roller and then placing it into the jack on the frame, the installation of the roller can be completed. Although this roller installation is fast, its stability is insufficient and it cannot guarantee the stability during straightening or descaling. When using the method of internal thread connection to install the rollers, although the stability is better, the installation efficiency is slower, which affects the installation efficiency of the tension leveling descaling machine. At the same time, after the rollers on the tension leveling machine are installed, it is not convenient to adjust the position of the rollers, and the distance and pressure between the rollers cannot be adjusted according to the different thicknesses, widths and hardnesses of the steel coil or steel strip. Content of the Utility Model

An extrusion block 25 is arranged on one side of the middle column rod 24; the adjusting component group 03 includes a moving mounting plate 31. A moving guide rail component 32 is arranged on the side of the moving mounting plate 31. A fixed guide rail frame 33 is arranged on the side of the moving guide rail component 32. A fixed side frame 34 is connected to the side of the fixed guide rail frame 33. A moving side frame 35 is connected to the side of the moving guide rail component 32. A bolt assembly 36 is arranged inside the moving side frame 35.

[0025] There are two sets of the threaded rod component 21, the vertical guide rail frame 22 and the adjusting block 23, and the two sets of the threaded rod component 21, the vertical guide rail frame 22 and the adjusting block 23 are symmetrically distributed on both sides of the moving mounting plate 31. The vertical guide rail frame 22 is connected to the moving mounting plate 31. Both ends of the threaded rod component 21 are connected to the vertical guide rail frame 22 through bearings. One end of the threaded rod component 21 is connected with a knob.

[0026] Inside the adjusting block 23, there is a sleeve connected by a bearing, and the sleeve is connected to the threaded rod member 21 through a thread. One side of the adjusting block 23 is in sliding contact with the vertical guide rail frame 22 through a chute.

[0027] The middle column rod 24 is connected between two adjusting blocks 23 through a rotating shaft. The middle column rod 24 is connected to the extrusion block 25 through a connecting arm. The extrusion block 25 contacts the roller side rod 13. The moving mounting plate 31 is provided with a groove at the position corresponding to the roller side rod 13, and the moving mounting plate 31 and the roller side rod 13 are in contact through the groove. The extrusion block 25 is in contact with the roller side rod 13 through the groove.

[0028] There are two sets of moving guide rail members 32, fixed guide rail frames 33, fixed side frames 34, moving side frames 35 and bolt assemblies 36, and the two sets of moving guide rail members 32, fixed guide rail frames 33, fixed side frames 34, moving side frames 35 and bolt assemblies 36 are symmetrically distributed on both sides of the moving mounting plate 31.

[0029] The moving guide rail member 32 is connected to the side surface of the moving mounting plate 31, and the fixed guide rail frame 33 is connected to the main frame 11.

[0030] The moving guide rail member 32 and the fixed guide rail frame 33 are in sliding contact. The fixed side frame 34 and the moving side frame 35 are connected through the bolt assembly 36. The fixed side frame 34 is provided with a plurality of through holes at the position corresponding to the bolt assembly 36. The bolt assembly 36 includes a bolt and a nut. Through the cooperation of the bolt and the nut, the connection between the moving side frame 35 and the fixed side frame 34 is completed.

[0031] Working principle: Currently, there is a lack of a stable and fast installation method between the upper roller and the frame of the tension leveling and descaling machine. The extrusion installation component group 02 and the adjustment component group 03 designed in this technology, when installing the roller side rod 13 onto the main frame 11, directly place the roller side rod 13 into the groove provided for the roller side rod 13 on the moving mounting plate 31. After placing it, by rotating the middle column rod 24, the middle column rod 24 drives the extrusion block 25 through the connecting arm, so that the extrusion block 25 moves into the groove provided for the roller side rod 13 on the moving mounting plate 31. Subsequently, control the rotation of the knob at one end of the threaded rod member 21, so that the threaded rod member 21 rotates and drives the sleeve in the adjustment block 23 through the thread. The sleeve will move up and down on the threaded rod member 21, thereby being able to drive the middle column rod 24 to move. As the middle column rod 24 moves, it will control the extrusion block 25 to slide in the moving mounting plate 31, making the extrusion block 25 move downward. By squeezing the roller side rod 13 with the extrusion block 25, the roller side rod 13 is squeezed between the extrusion block 25 and the groove of the moving mounting plate 31, completing the installation between the roller side rod 13 and the main frame 11. This overall design does not require using bolts to connect the roller side rod 13 and the main frame 11. When installing and disassembling the roller side rod 13, only need to control the rotation direction of the threaded rod member 21 at one end, and then control the up and down position of the extrusion block 25 to squeeze or not squeeze the roller side rod 13, then the installation or disassembly between the roller side rod 13 and the main frame 11 can be completed, improving the installation and disassembly efficiency of the roller member 12 and the roller side rod 13, and further improving the installation and use efficiency of the overall tension leveling and descaling machine. After installing the roller member 12 and the roller side rod 13, when adjustment is required according to the thickness of the steel coil or steel strip, by removing the bolt assembly 36, the moving mounting plate 31 and the moving guide rail member 32 can slide up and down at the position of the fixed guide rail frame 33. After adjusting to the appropriate position, by connecting the bolt assembly 36 to the fixed side frame 34 and the moving side frame 35, the position locking of the moving mounting plate 31 is completed. The design of this adjustment component group 03 can still adjust the height of the roller member 12 and the roller side rod 13 after the installation of the roller member 12 and the roller side rod 13 is completed, and thus can adapt to steel coils or steel strips of different thicknesses.
