Clamping and adjusting device for continuous casting machines

Abstract

This utility model discloses a clamping and adjusting device for a continuous casting machine, including a base and a rotating frame. Clamping components are arranged around the rotating frame. Each clamping component includes surrounding support columns, with a mounting frame slidably arranged inside the support columns. A clamping roller is rotatably arranged inside the mounting frame, and a fixing port is provided at the top of the clamping roller. In this utility model, the billet is placed on the support rollers and positioned inside the surrounding clamping rollers. An electric telescopic rod pushes the mounting frame, causing the inner clamping rollers to clamp the billet. When only the billet is clamped, a fixing block can be inserted into the fixing port by rotating a bolt at the top, thus fixing the clamping rollers and reinforcing the billet. If the billet shifts, a motor drives a gear to rotate, which in turn rotates the rotating frame and clamping components, adjusting the direction of the billet to keep it facing the continuous casting machine.

Description

Technical Field

[0001] This utility model relates to the field of continuous casting machine technology, specifically to a clamping and adjusting device for a continuous casting machine. Background Technology

[0002] A continuous casting machine is a crucial piece of equipment used to continuously cast molten steel into steel billets. Its workflow is roughly as follows: molten steel is poured from the steelmaking furnace into a ladle, then evenly distributed through a tundish into a crystallizer. The crystallizer cools the molten steel, causing it to initially solidify and form a billet shell. Next, the solidified billet is pulled out of the crystallizer by a leveling machine and further cooled and solidified in a secondary cooling zone. Finally, a cutting device cuts the billet to a specified length, yielding the finished steel billet. Continuous casting machines improve steel production efficiency, reduce energy consumption, and ensure uniform and stable billet quality, making them widely used in the continuous casting production process of the steel industry.

[0003] In the continuous steel casting process, a clamping device is required to hold the billet. However, existing clamping devices have certain problems when clamping the billet. When the billet moves, the frictional resistance between the traditional clamping device and the billet is large, which not only increases the energy consumption of the equipment, but may also damage the surface of the billet. When the billet deviates during the conveying process, the traditional device is difficult to adjust the direction automatically and often relies on manual operation, which increases labor intensity and reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a clamping and adjusting device for a continuous casting machine, in order to solve the problems mentioned in the background art, such as the large frictional resistance between the traditional clamping device and the billet when the billet moves, and the difficulty of the traditional device to automatically adjust the direction when the billet deviates during the conveying process.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A clamping and adjusting device for a continuous casting machine includes a base and a rotating frame, wherein clamping components are arranged around the rotating frame;

[0007] The clamping assembly includes four supporting columns, a mounting frame is slidably arranged inside the supporting columns, a clamping roller is rotatably arranged inside the mounting frame, and a fixing port is provided at the top of the clamping roller.

[0008] In a preferred embodiment of this utility model, a rotating bolt is provided on the inner side of the base, and the rotating frame is rotatably mounted on the rotating bolt.

[0009] In a preferred embodiment of this utility model, a motor is provided on one side of the base, a gear is provided on the motor drive shaft, and a sector tooth is provided on one side of the rotating frame, with the gear meshing with the sector tooth.

[0010] In a preferred embodiment of this utility model, a support frame is provided above the base, and a support roller is rotatably arranged inside the support frame.

[0011] In a preferred embodiment of this utility model, an electric telescopic rod is provided at the top of the support column, and the telescopic end of the electric telescopic rod is connected to the support column.

[0012] In a preferred embodiment of the present invention, a sliding groove is provided on the top of the mounting bracket, and a slider is slidably disposed inside the sliding groove.

[0013] In a preferred embodiment of this utility model, a fixing block is provided at the bottom of the slider, and the fixing block is installed and removed in the fixing port.

[0014] In a preferred embodiment of this utility model, the top of the slide groove is provided with a threaded opening, and a bolt is provided inside the threaded opening. The bolt is threadedly connected to the threaded opening, and the bottom of the bolt is rotatably connected to the slider.

[0015] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention.

[0016] Beneficial effects: The billet is placed on the support rollers and inside the clamping rollers. The mounting frame is pushed by an electric telescopic rod, which causes the inner clamping rollers to clamp the billet. When the billet moves, the rotation of the clamping rollers and support rollers reduces friction. When only the billet is clamped, the clamping rollers are fixed by rotating the bolts at the top and inserting the fixing block into the fixing port, thus strengthening the fixation of the billet. When the billet deviates, the motor drives the gear to rotate. Through gear transmission, the rotating frame and clamping assembly rotate, thereby adjusting the direction of the billet and keeping it facing the continuous casting machine.

[0017] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it according to the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings.

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Please refer to Figures 1-4 This utility model relates to a clamping and adjusting device for a continuous casting machine, comprising a base 1 and a rotating frame 2. The base 1 is the bottom structure of the device, used to support the overall structure. The rotating frame 2 is the mounting structure. A rotating bolt 11 is provided on the inner side of the base 1, and the rotating frame 2 is rotatably mounted on the rotating bolt 11. A motor 12 is provided on one side of the base 1, and a gear 13 is provided on the drive shaft of the motor 12. A sector tooth 21 is provided on one side of the rotating frame 2, and the gear 13 meshes with the sector tooth 21. The motor 12 is a stepper motor. When clamping the billet or when the billet is being conveyed and the billet deviates, the motor 12 can drive the gear 13 to rotate. Through gear transmission, the rotating frame 2 and the clamping assembly are rotated, thereby adjusting the direction of the billet and keeping it facing the continuous casting machine. All electrical equipment in the device is controlled by an external controller, which is a conventional technical means for those skilled in the art.

[0026] A support frame 14 is provided above the base 1. A support roller 15 is rotatably installed inside the support frame 14. A clamping assembly is provided around the rotating frame 2. The clamping assembly includes a support column 22. A mounting frame 24 is slidably installed inside the support column 22. A clamping roller 25 is rotatably installed inside the mounting frame 24. An electric telescopic rod 23 is provided at the top of the support column 22. The telescopic end of the electric telescopic rod 23 is connected to the support column 22. The billet is placed on the support roller 15 and is inside the clamping roller 25. At this time, the mounting frame 24 can be pushed by the electric telescopic rod 23, so that the clamping roller 25 on the inner side clamps the billet. The electric telescopic rods 23 on all four sides can extend and retract, so that billets of different shapes can be clamped. When the billet moves, the friction is reduced by the rotation of the clamping roller 25 and the support roller 15.

[0027] The clamping roller 25 has a fixing port 32 at its top, and the mounting bracket 24 has a sliding groove 3 at its top. A slider 33 is slidably mounted inside the sliding groove 3, and a fixing block 34 is provided at the bottom of the slider 33. The fixing block 34 is installed and removed in the fixing port 32. The top of the sliding groove 3 has a threaded opening 31, and a bolt 35 is installed inside the threaded opening 31. The bolt 35 is threadedly connected to the threaded opening 31, and the bottom of the bolt 35 is rotatably connected to the slider 33. When only the casting billet is clamped, the slider 33 can be slid in the sliding groove 3 by rotating the bolt 35 at the top, while the fixing block 34 is inserted into the fixing port 32, thereby fixing the clamping roller 25 and preventing it from rotating, thus strengthening the fixation of the casting billet.

[0028] The working principle of this utility model is as follows: The billet is placed on the support roller 15 and is located inside the clamping rollers 25. The mounting frame 24 is pushed by the electric telescopic rod 23, so that the inner clamping rollers 25 clamp the billet. The electric telescopic rods 23 on all four sides can extend and retract, so that billets of different shapes can be clamped. When the billet moves, the friction is reduced by the rotation of the clamping rollers 25 and the support roller 15. When only the billet is clamped, the slider 33 can be slid in the slide groove 3 by rotating the bolt 35 at the top, and the fixing block 34 is inserted into the fixing port 32 to fix the clamping roller 25 and prevent it from rotating, thus strengthening the fixation of the billet. When the billet deviates, the gear 13 can be rotated by the motor 12. Through gear transmission, the rotating frame 2 and the clamping assembly can be rotated to adjust the direction of the billet and keep it facing the continuous casting machine.

[0029] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
