Description

Technical Field

[0001] This utility model belongs to the field of stainless steel strip production technology, and relates to a stainless steel strip tempering device. Background Technology

[0002] In the process of processing and production, steel strip often needs to be quenched and tempered to improve its hardness and toughness. However, existing quenching and tempering devices are generally set up as two independent devices. After quenching, the steel strip needs to be transferred from the quenching device to the cooling device for rapid cooling. After cooling, the steel strip is then put into the tempering device for tempering.

[0003] The existing technology has the following technical problems: In existing steel strip production, quenching liquid remains on the surface after quenching. During tempering, workers need to manually wipe off the quenching liquid, resulting in low production efficiency. Some production lines combine quenching and tempering to achieve continuity, but such devices do not have the function of wiping off the quenching liquid, which leads to uneven heating of the steel strip during tempering and quality problems. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing steel strip production often leaves residual quenching liquid on the surface after quenching. During tempering, workers need to manually wipe away the quenching liquid, resulting in low production efficiency. Some manufacturers combine quenching and tempering into the same production line to achieve continuity, but this device lacks the ability to remove the quenching liquid, leading to uneven heating of the steel strip during tempering and quality problems.

The first conveying roller and the drive roller are connected by the drive pulley set.

[0008] The liquid collection assembly also includes two pressure rollers, which are respectively located at the upper middle position of the liquid absorption belt and the middle position inside the other liquid absorption belt. Both ends of the liquid absorption belt are connected to the second fixing frame through the pressure assembly. A liquid collection box is provided on the inner side of one liquid absorption belt and the outer side of the other liquid absorption belt at a position corresponding to the pressure roller. The liquid collection box is fixedly connected to the second fixing frame. A scraper is fixed at the middle position inside the liquid collection box, and the top of the scraper is in contact with the liquid absorption belt.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0021] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0022] Example 1

[0023] like Figures 1-5As shown, the device includes a fixed base 1, a quenching box 2 fixed to one end of the top of the fixed base 1, a tempering box 3 fixed to the other end of the top of the fixed base 1, a first fixing frame 4 fixed to the top of the fixed base 1 near the tempering box 3, a conveying component provided on the inner side of the first fixing frame 4 to facilitate the conveying of the steel strip, a second fixing frame 5 fixed to the top of the fixed base 1 near the quenching box 2, and a liquid collection component provided on the inner side of the second fixing frame 5 for wiping and collecting the quenching liquid on the surface of the steel strip.

[0024] The conveying assembly includes a first conveying roller 6, which is located at the lower inner end of the first fixed frame 4 and is rotatably connected to the first fixed frame 4. A second conveying roller 10 is rotatably connected to the inner top of the first fixed frame 4 and at a position symmetrical to the first conveying roller 6, so that the steel belt can be moved by rotating the second conveying roller 10 and the first conveying roller 6 in opposite directions. One end of both the first conveying roller 6 and the second conveying roller 10 extends to the outer side of the first fixed frame 4. A drive gear 7 and a transmission gear 8 are respectively fixed at the outer ends of the first conveying roller 6 and the second conveying roller 10. A drive motor 9 is fixed at the top of the fixed base 1 and at a position corresponding to the drive gear 7. The output end of the drive motor 9 is fixedly connected to the drive gear 7.

[0025] During operation, the drive motor 9 is started, causing the first conveying roller 6 and the drive gear 7 fixed to the first conveying roller 6 to rotate. When the drive gear 7 rotates, it drives the second conveying roller 10 fixed to the transmission gear 8 to rotate simultaneously through the transmission gear 8 meshing with it. Thus, the steel strip located between the first conveying roller 6 and the second conveying roller 10 is conveyed through the relative rotation of the first conveying roller 6 and the second conveying roller 10. After the steel strip passes through the quenching box 2, the quenching liquid on the surface of the steel strip is wiped off and collected by the liquid collection component. Finally, the tempering of the steel strip is completed in the tempering box 3. Through the cooperative structural design of the conveying component and the liquid collection component, when the steel strip is conveyed from the quenching box 2 to the inside of the tempering box 3 for tempering, the quenching liquid on the surface of the steel strip can be wiped off and absorbed by the liquid collection component, thereby avoiding the residue of quenching liquid on the surface of the steel strip, improving the quality of the steel strip after tempering, and increasing work efficiency.

[0026] Example 2

[0027] like Figure 5As shown, the liquid collection assembly includes multiple drive rollers 11, which are symmetrically arranged on the inner side of the second fixed frame 5. The outer sides of two drive rollers 11 on the same horizontal line are fitted with liquid-absorbing belts 12, which can absorb the quenching liquid on the surface of the steel strip. A drive pulley set 13 is provided between one end of the drive roller 11 close to the first conveying roller 6 and the first conveying roller 6. In order to facilitate the simultaneous rotation of the drive roller 11 when the first conveying roller 6 rotates, the first conveying roller 6 and the drive roller 11 are connected by the drive pulley set 13.

[0028] To facilitate pressurizing the liquid-absorbing belt 12 so that the drive roller 11 can rotate and drive the liquid-absorbing belt 12 to roll, the liquid collection assembly also includes two pressure rollers 14. The two pressure rollers 14 are respectively located at the upper middle position of the liquid-absorbing belt 12 and the middle position of the inner side of the other liquid-absorbing belt 12. Both ends of the liquid-absorbing belt 12 are connected to the second fixing frame 5 through the pressure assembly. To facilitate scraping and collecting the quenching liquid adsorbed on the surface of the liquid-absorbing belt 12, the inner side of one liquid-absorbing belt 12 and the outer side of the other liquid-absorbing belt 12 are positioned corresponding to the pressure rollers 14. Each is equipped with a liquid collection box 15, which is fixedly connected to the second fixed frame 5. A scraper 19 is fixed at the middle position of the inner side of the liquid collection box 15, and the top of the scraper 19 is in contact with the liquid suction belt 12. In order to facilitate the collection of quenching liquid inside the two liquid collection boxes 15, a liquid guide pipe 16 is fixed at one end of one liquid collection box 15, and a drainage pipe 17 is fixed at one end of the other liquid collection box 15. The lower end of the liquid guide pipe 16 is fixedly connected to the drainage pipe 17, and the liquid guide pipe 16 and the drainage pipe 17 are connected. A liquid collection tank 18 is fixed at the lower end of the drainage pipe 17.

[0029] The pressurizing assembly includes a sliding block 20, which is fixed at the end of the pressurizing roller 14. A fixed slide rod 21 is fixed on the inner side of the second fixing frame 5 at a position corresponding to the sliding block 20. The sliding block 20 and the fixed slide rod 21 are slidably connected. In order to facilitate the pressurization of the pressurizing roller 14 through the sliding block 20, a limit spring 22 is fixed at the top of the sliding block 20. The end of the limit spring 22 away from the sliding block 20 is fixedly connected to the second fixing frame 5.

[0030] When the first conveying roller 6 rotates, it drives the transmission roller 11 to rotate through the transmission pulley group 13. When the transmission roller 11 rotates, it drives the liquid suction belt 12 to roll along the outer diameter of the transmission roller 11. Then, the liquid suction belt 12 absorbs the quenching liquid on the surface of the steel strip. When the liquid suction belt 12 moves to the bottom of the pressure roller 14 after absorption, the pressure roller 14, under the elastic action of the limit spring 22, causes the sliding block 20 to drive the pressure roller 14 to continuously squeeze towards the liquid suction belt 12. Then, under the squeezing action of the pressure roller 14 and the scraper 19, the quenching liquid on the surface of the liquid suction belt 12 is squeezed out and collected into the inside of the liquid collection box 15. Finally, it enters the inside of the liquid collection tank 18 through the liquid guide pipe 16 and the drainage pipe 17, thus completing the collection of quenching liquid.

[0031] The descriptions of the orientation and relative positional relationships of the structure in this utility model, such as descriptions of front, back, left, right, up, and down, do not constitute a limitation on this utility model, but are merely for the convenience of description.
