Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of material traction, in particular to a material pulling and traction device that is conducive to long-term accurate pressure regulation. Background Art
[0002] In the field of adjustable pressure material pulling and traction devices, traditional devices usually use directly contacting sliding components for material traction. The working principle of such devices is to achieve continuous pulling of materials through the close fit between the sliding column and the sliding groove. However, in practical applications, this design has some problems, such as:
[0003] 1. Due to long-term continuous operation, the direct friction between the sliding column and the sliding groove will cause rapid wear of the components, thereby affecting the accuracy of the device. This wear not only reduces the service life of the device but also increases the maintenance cost.
[0004] 2. To alleviate this wear, lubricants or wear-resistant materials are often used in the industry. However, these methods cannot fundamentally solve the problem. Lubricants may fail due to high temperature or contamination, while wear-resistant materials may increase the device cost and affect the overall performance.
[0005] 3. The traditional design is prone to vibration and deviation during the traction process, resulting in unstable material traction, further affecting production efficiency and product quality.
[0006] Therefore, how to maintain the accuracy of the device after long-term use, reduce the wear of sliding components, lower the maintenance cost, and improve the traction stability has become the technical problem to be solved by the utility model. Summary of the Utility Model

[0016] The back surface of the sliding seat is fixedly connected to the vertical plate seat. A sliding cavity groove penetrating the upper end and the lower end of the sliding seat is arranged on the front surface of the sliding seat. The slider is located in the sliding cavity groove. The end of the pressure roller is rotationally and cooperatively connected to the slider through a bearing.
[0017] First sliding grooves are respectively arranged on the two sides of the slider.

[0025] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0026] 1. Maintain long-term accuracy: After long-term continuous operation, the accuracy of traditional traction devices often gradually decreases due to the direct friction and continuous force of sliding components. However, the gap design of the present application effectively inhibits this accuracy decline caused by long-term wear by reducing the direct contact between the sliding column and the sliding groove. The gap provides a stable movement trajectory for the sliding column and disperses the force application points, thereby ensuring that the device can still maintain high accuracy during long-term high-intensity use and meeting the requirements of precision manufacturing.
[0027] 2. Reduce the risk of damage to sliding components: During long-term traction operations, the traditional direct contact design often easily leads to damage to sliding components due to continuous force. However, through the gap design of the present device, the sliding column forms an indirect contact with multiple gaps between the first sliding groove and the second sliding groove during traction, effectively reducing friction and wear, thereby significantly reducing the risk of damage to sliding components.
[0028] 3. Extend the service life of the device: Due to the existence of the gap design, the contact area between the sliding column and the sliding groove is reduced, and the pressure per unit area is also correspondingly reduced. This design not only reduces the concentration of mechanical stress but also slows down the fatigue speed of the material, thereby effectively extending the service life of the device.
[0029] 4. Improve traction stability: The design of multiple gaps provides stable guiding support for the sliding column while ensuring its flexible movement. This design makes the traction process smoother, reduces vibration and deviation, and improves the overall traction stability.

[0046] Embodiment 1:
[0047] In this embodiment, the adjustable pressure pulling and traction device is applied to the material conveying link of a continuous production line. This production line requires the material to maintain stable accuracy during high-speed traction to ensure the smooth progress of subsequent processing procedures. Due to the decrease in accuracy after long-term operation, the traditional traction device often causes deviation of the material during transportation, seriously affecting the production efficiency and product quality.
[0048] To solve this problem, we adopt the adjustable pressure pulling and traction device proposed in this patent application. Specifically, the device includes the sliding column 16 and a traction component provided with the first sliding groove 14 and the second sliding groove 15. The sliding column 16 realizes indirect contact through a plurality of gaps formed between the first sliding groove 14 and the second sliding groove 15 during the traction process. This design significantly reduces the direct friction between the sliding column 16 and the sliding groove, thereby reducing the wear speed and extending the service life of the equipment.
[0049] In practical applications, due to the existence of the gaps, when the sliding column 16 is subjected to the traction force, the stress can be more evenly distributed, avoiding the problem of stress concentration. This not only improves the load-bearing capacity of the sliding column 16, but also is conducive to maintaining the shape stability of the sliding column 16, thereby ensuring the accuracy of material traction. Even after continuous working for several hours, the device can still maintain the initial accuracy, greatly reducing the deviation during the material transportation process.
[0050] In practical applications, the sliding column 16 can be made of plastic material. This choice is not only for cost and processing convenience considerations, but more importantly, the plastic material has certain elasticity and deformation recovery ability. Combining the existence of the gap design, this material property enables the sliding column 16 to exhibit excellent performance when subjected to traction force. Specifically, when the sliding column 16 is subjected to the traction force, due to the elasticity of its plastic material, it can undergo an appropriate amount of elastic deformation under the guidance of the gap. This deformation not only effectively disperses the stress and avoids excessive stress concentration in local areas, but also can quickly return to its original shape after the external force is removed, thus maintaining the shape stability of the sliding column. In addition, the combination of the plastic material sliding column 16 and the gap design further improves the wear resistance and service life of the device. Traditional metal sliding columns often experience performance degradation due to friction and wear after long-term use. However, the plastic material sliding column 16, due to its good self-lubricity and wear resistance, and the gap design reduces the direct contact area with the chute, thus significantly reducing the wear rate and extending the service life of the device.
