Abstract
Description
Technical Field
[0001] This utility model relates to the field of seamless calcium wire technology, specifically a novel steel strip buffer device for seamless calcium wire production. Background Technology
[0002] Seamless calcium wire is an upgraded alternative to seamed calcium wire. It can purify the inclusions in molten steel, improve the castability of molten steel, and enhance the performance of steel. When producing seamless calcium wire, after one roll of steel strip is used up, the ends of two rolls need to be welded together using a welder, requiring the machine to be stopped for welding, which greatly reduces work efficiency. Usually, a steel strip buffer device is needed to buffer the steel strip. However, in the use of existing buffer devices, the pressure on the steel strip is in one direction, which can easily lead to uneven pressure on the steel strip and damage to the steel strip. Utility Model Content
[0003] To address the above problems, the purpose of this utility model is to provide a novel steel strip buffer device for seamless calcium wire production, which solves the problem that in the use of existing buffer devices, the pressure on the steel strip is in one direction, which easily leads to uneven pressure on the steel strip and damage to the steel strip.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a novel steel strip buffer device for seamless calcium wire production, comprising a mounting bracket and a drive motor. A drive device is mounted on top of the mounting bracket, and the output end of the drive device is connected to a steel coil via a reducer. A buffer device body is disposed on the outer side of the mounting bracket, and a conveying roller is mounted on the inner side of the buffer device body. The drive motor is mounted on the outer side of the buffer device body, and a lead screw is connected to the output end of the drive motor. A slider is mounted on the lead screw, and a support roller group is connected to the inner side of the slider. A hydraulic cylinder is mounted at the top of the buffer device body, and a connecting ring is connected below the hydraulic cylinder. A guide roller is mounted in the middle of the connecting ring, and a gear one is connected to the guide roller. A gear two is meshed below the gear one, and a bottom support roller is mounted at the shaft center of the gear two. A mounting frame is mounted below the guide roller and the bottom support roller.
[0005] The beneficial effects of this utility model are as follows: during the descent of the steel strip, the bottom support roller supports the steel strip, and the drive motor drives the support roller group through the lead screw and slider to always be in close contact with the steel strip as the guide roller descends, ensuring that the steel strip is subjected to uniform force. This method can effectively ensure the force on the steel strip and avoid damage to the steel strip.
[0006] To facilitate contact between the support roller assembly and the steel strip:
[0007] As a further improvement to the above technical solution, the support roller group is set at an angle.
[0008] The beneficial effect of this improvement is that the inclined support roller group can make the support roller group fit tightly with the steel strip.
[0009] To facilitate the raising and lowering of the guide rollers:
[0010] As a further improvement to the above technical solution: the guide roller and the buffer device body are connected by a hydraulic cylinder to form a lifting and mounting structure.
[0011] The beneficial effects of this improvement are: the guide roller can be reliably and smoothly raised and lowered by the hydraulic cylinder, which facilitates the buffering of the steel strip.
[0012] To support the steel strip:
[0013] As a further improvement to the above technical solution: two bottom support rollers are symmetrically arranged about the axis of the guide roller.
[0014] The beneficial effect of this improvement is that the two symmetrically arranged bottom support rollers can work with the guide rollers to support the bottom of the steel strip.
[0015] To facilitate the sliding of the support roller assembly:
[0016] As a further improvement to the above technical solution: a guide light rod is connected to the side of the support roller group away from the slider.
[0017] The beneficial effect of this improvement is that the guide rod can guide the other side of the support roller group, ensuring reliable and stable sliding of the support roller group.
[0018] As a further improvement to the above technical solution: the slider and the buffer device body are arranged in parallel to each other.
[0019] The beneficial effect of this improvement is that the parallel arrangement of the sliders makes the sliding of the support roller group more reliable and stable.
[0020] To facilitate the installation of the guide roller and the bottom support roller:
[0021] As a further improvement to the above technical solution: the mounting bracket adopts a U-shaped configuration.
[0022] The beneficial effect of this improvement is that the U-shaped mounting bracket makes the installation of the guide roller and the bottom support roller more reliable.
[0023] To facilitate the raising and lowering of the guide rollers:
[0024] As a further improvement to the above technical solution: the hydraulic cylinder and the buffer device body are arranged perpendicularly to each other.
[0025] The beneficial effect of this improvement is that the mutually perpendicular arrangement makes the hydraulic cylinder drive the guide rollers to rise and fall more reliably. Attached Figure Description

[0032] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of this utility model in any way.
[0033] like Figure 1-5As shown, a novel steel strip buffer device for seamless calcium wire production includes a mounting bracket 1 and a drive motor 3. A drive device 11 is mounted above the mounting bracket 1, and the output end of the drive device 11 is connected to a steel coil 12 via a reducer. A buffer device body 2 is disposed on the outer side of the mounting bracket 1, and a conveying roller 21 is mounted on the inner side of the buffer device body 2. The drive motor 3 is mounted on the outer side of the buffer device body 2, and a lead screw 31 is connected to the output end of the drive motor 3. A slider 32 is mounted on the lead screw 31, and a support roller group 33 is connected to the inner side of the slider 32. A top end of the buffer device body 2 is... A hydraulic cylinder 4 is provided, and a connecting ring 41 is connected to the lower part of the hydraulic cylinder 4. A guide roller 42 is installed in the middle of the connecting ring 41, and a gear 43 is connected to the guide roller 42. A gear 44 is meshed below the gear 43, and a bottom support roller 45 is installed at the axis of the gear 44. A mounting frame 46 is installed below the guide roller 42 and the bottom support roller 45. During the descent of the steel strip, the bottom support roller 45 supports the steel strip. The drive motor 3 drives the support roller group 33 through the lead screw 31 and the slider 32 to always keep it in close contact with the steel strip as the guide roller 42 descends, ensuring that the steel strip is subjected to uniform force. This method effectively ensures the stress on the steel strip and avoids damage. The support roller group 33 is inclined, which allows it to fit tightly against the steel strip. The guide roller 42 and the buffer device body 2 are connected by a hydraulic cylinder 4 to form a lifting and lowering structure. The hydraulic cylinder 4 can reliably and smoothly lift and lower the guide roller 42, thus facilitating the buffering of the steel strip. There are two bottom support rollers 45 symmetrically arranged about the axis of the guide roller 42. These two symmetrically arranged bottom support rollers 45 can work with the guide roller 42 to support the bottom of the steel strip. The support roller group 33 is located away from the slider 32. One side is connected to a guide rod, which guides the other side of the support roller group 33 to ensure reliable and stable sliding of the support roller group 33. The slider 32 and the buffer device body 2 are arranged in parallel to each other. The parallel arrangement makes the slider 32 drive the support roller group 33 to slide more reliably and smoothly. The mounting bracket 46 is U-shaped. The U-shaped mounting bracket 46 makes the installation of the guide roller 42 and the bottom support roller 45 more reliable. The hydraulic cylinder 4 and the buffer device body 2 are arranged perpendicular to each other. The perpendicular arrangement makes the hydraulic cylinder 4 drive the guide roller 42 to rise and fall more reliably.
[0034] The working principle of this utility model is as follows: When using the device, it is installed in a designated position. When buffering is required, the hydraulic cylinder 4 pushes the connecting ring 41 to descend. The guide roller 42, in conjunction with the bottom support roller 45, drives the steel belt to descend. During the descent, the bottom support roller 45 supports the steel belt. The drive motor 3 drives the lead screw 31 to rotate, which in turn drives the support roller group 33 to move. The support roller group 33 separates from the guide roller group 33, so that the support roller group 33 always closely contacts the steel belt as the guide roller 42 descends, ensuring that the steel belt is evenly stressed. As the steel belt continues to move, the hydraulic cylinder 4 drives the guide roller 42 and the steel belt to rise and the drive motor 3 to reverse. This method can effectively ensure the stress on the steel belt and avoid damage to the steel belt.
