Description

Technical Field

[0001] This utility model relates to the field of straightening and guiding technology, specifically a straightening and guiding cylinder with a protective structure. Background Technology

[0002] In modern metal processing industries, the use of guide cylinders with roller-type protective structures for straightening and conveying metal parts is a crucial and common basic process. In this process, the rollers, as core components, play a decisive role, much like the key gears in precision instruments, in the smoothness of metal part conveying, the accuracy of positioning, and the final surface quality, due to their rotational flexibility and stability.

[0003] However, current lubrication technology at the connection between rollers and machinery faces numerous unresolved issues. From an operational perspective, traditional lubrication methods require the equipment to be completely stopped before lubrication can begin. In actual production scenarios, especially in large metal processing enterprises pursuing continuous and efficient production, the impact of downtime is multifaceted and far-reaching. Each downtime, besides directly interrupting the production rhythm, triggers a series of chain reactions. For example, restarting the equipment consumes electrical energy, undoubtedly increasing production costs; and delays in production progress, taking a large metal pipe straightening production line as an example, can produce hundreds of meters of pipe per hour. If the production line is halted for half an hour due to lubrication, not only will hundreds of meters of pipe be lost directly, but subsequent rush work may also increase labor and equipment wear and tear costs, severely impacting the company's economic benefits.

[0004] From the perspective of precision and adaptability of lubrication methods, the current method of manually adding lubricant has serious inherent shortcomings. Due to the lack of standardized dosage specifications, it relies entirely on the operator's experience and judgment, resulting in significant fluctuations in lubrication effectiveness. Adding too much lubricant not only causes drips onto the production workshop floor, creating a dirty and messy working environment, increasing cleaning costs and safety hazards, but may also form excess oil film on metal parts, affecting subsequent processing steps. Conversely, adding too little lubricant fails to form an effective lubricating film at the roller and mechanical connection points, leading to increased friction between components, accelerated equipment wear, and a shortened equipment lifespan.

[0005] A more challenging aspect is that existing lubrication methods fall short when dealing with the diverse types and properties of metal parts involved in metal processing. Metal parts of varying hardness exhibit drastically different frictional forces with the rollers during straightening. Harder metals, such as special alloy steels, require greater external force during straightening, increasing the pressure on the rollers, leading to more pronounced frictional heat generation, and thus a greater need for lubrication. Conversely, softer metals, such as aluminum alloys, while requiring relatively less straightening force, are more prone to surface scratches due to their softer texture, demanding extremely uniform lubrication. Similarly, metal parts with varying degrees of curvature experience significantly different contact states and force conditions with the rollers as they pass through the guide cylinder. Metal parts with large curvature exert significant impact on the rollers during the initial straightening phase, requiring frequent and ample lubrication for cushioning. While metal parts with smaller curvature experience relatively stable force, long-term lubrication maintenance is still essential. Therefore, the development of more efficient and higher-quality straightening equipment that flexibly and promptly adjusts lubrication frequency and volume to meet diverse production needs is urgently needed.

[0006] Therefore, we propose a straightening guide cylinder with a protective structure to solve the above problems. Utility Model Content

[0018] (III) Beneficial Effects

[0019] Compared with the prior art, the present invention provides a straightening guide cylinder with a protective structure, which has the following beneficial effects:

[0020] 1. Through its design, this utility model can bring the following benefits to the overall operation:

[0021] Improving production efficiency: Traditional lubrication methods require machine shutdown, interrupting the production process. This new equipment, however, lubricates while the equipment is running, avoiding downtime and ensuring continuous production. For example, in a metal pipe straightening production line, if a one-hour downtime due to lubrication is previously possible, using the new equipment can reduce that downtime loss, allowing the production line to continue outputting and significantly increasing output per unit time.

[0022] Reduce equipment wear: Insufficient lubrication between the roller shaft and the fixed contact point will lead to accelerated wear of components and shorten the service life of the equipment. New equipment provides timely and effective lubrication, reducing friction between components and minimizing wear. For example, roller shafts that previously required frequent replacement can have their replacement cycle extended thanks to the newly designed lubrication system, reducing the cost of equipment maintenance and parts replacement.

[0023] Improving product quality: Stable lubrication ensures smooth roller rotation, allowing metal parts to be subjected to uniform force during straightening and conveying. For high-precision metal processing, such as aerospace component manufacturing, it can avoid problems such as surface scratches and deformation of metal parts caused by roller jamming or uneven friction, thereby improving the dimensional accuracy and surface quality of products and reducing the defect rate.

[0024] 2. Through its design, this utility model can bring the following benefits to the overall operation:

[0025] Significant energy savings and consumption reduction: The lubrication components are driven by the rotation of roller shafts, eliminating the need for additional drive devices and avoiding extra energy consumption. In large-scale metal processing production, if many pieces of equipment use traditional lubrication systems with independent drives, the cumulative energy consumption will be enormous. This equipment's self-driving method reduces energy input at the source, aligning with the current trend of green and energy-saving industrial production. In the long run, it can save companies a significant amount of electricity costs.

[0026] Improving equipment reliability and stability: Reducing additional drive components also reduces potential points of failure. Drive components are often the most complex and prone to failure parts of the equipment; eliminating these components significantly improves the overall reliability and operational stability of the equipment.

[0027] Enhanced production flexibility and precision: Operators can flexibly increase lubrication frequency based on the straightening difficulty of metal parts or the degree of surface rust. When handling high-hardness, severely bent, or heavily rusted metal parts, timely increases in lubrication frequency ensure good contact between the rollers and the metal parts, preventing surface damage and poor conveying caused by excessive friction. Lubrication strategies can be quickly adjusted for different batches and characteristics of metal parts, meeting diverse production needs, improving production precision and efficiency, and resulting in more stable and reliable product quality.

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0039] Example

[0040] Please refer to Figures 1 to 7 As shown:

[0041] A straightening guide cylinder with a protective structure includes a guide cylinder 1. Support members 2 are symmetrically fixedly connected inside the guide cylinder 1. A roller shaft 3 is rotatably connected to the support member 2. A roller 4 is fixedly connected to the roller shaft 3. An N-shaped member 5 is fixedly connected inside the support member 2. An electric drive gear 6 is rotatably connected to the N-shaped member 5. A driven gear 7 is fixedly connected to the roller shaft 3. The electric drive gear 6 and the driven gear 7 mesh appropriately. A switching cavity 8 is opened at the outer end of the roller shaft 3. An electromagnet 9 is fixedly connected inside the switching cavity 8. A metal plate 10 is provided on one side of the electromagnet 9. A transverse rod 11 is fixedly connected to one end face of the metal plate 10. A rotating column 12 is provided on the same transverse straight line as the transverse rod 11. The transverse rod 11 is slidably connected to the rotating column 12. In the moving column 12, a surrounding groove 13 is formed on the outer surface of the rotating column 12. An arc plate 14 is fixedly connected to the inner cavity of the support member 2. A stabilizing rod 15 is fixedly connected to the arc plate 14. A spring 16 is sleeved on the stabilizing rod 15. A sliding rod 17 is slidably connected in the surrounding groove 13. A fixed plate 1701 is slidably connected in the support member 2. The sliding rod 17 is rotatably connected to the fixed plate 1701. A right-angle push rod 18 is fixedly connected to the fixed plate 1701. A transfer plug 19 is sleeved at the end of the right-angle push rod 18 away from the fixed plate 1701. A through hole 20 is formed on the transfer plug 19. A lubricating oil tank 21 is fixedly connected above the through hole 20 and located on the transfer plug 19. A transfer tube 22 is fixedly connected to the support member 2.

[0042] in:

[0043] A silicone strip is fixedly connected to the outer periphery of the metal sheet 10. It is mainly used to drive the rotating column 12 to rotate under the action of magnetic force and friction after the electromagnet 9 and the metal sheet 10 are magnetically attracted.

[0044] The transverse lever 11 consists of a spring body and a transverse column.

[0045] The lubricating oil tank 21 is connected to the transfer plug cylinder 19 through the through hole 20; the transfer pipe 22 is equipped with a one-way valve, which can only transfer the solution in one direction.

[0046] The device is symmetrically arranged inside the guide cylinder 1, with the symmetrical components positioned opposite each other, so that the other transfer tube 22 can be lubricated.

[0047] Working principle:

[0048] When it is necessary to lubricate the connection between the rotating roller shaft 3 and the support 2, the operator can energize the electromagnet 9. At this time, the metal plate 10 will be magnetically attracted and slid into the switching cavity 8 opened on the roller shaft 3 under the action of the transverse rod 11 on the rotating column 12. Furthermore, during this process, the silicone strip on the metal plate 10 can increase the friction between the inner wall of the switching cavity 8 and the metal plate 10. Under the action of magnetic attraction, the roller shaft 3 will indirectly drive the rotating column 12 to rotate.

[0049] Furthermore, during the rotation of the rotating column 12, the arc-shaped plate 14 provides support. Additionally, since the fixed plate 1701 is slidably connected to the inner wall of the support member 2, and the sliding rod 17 is slidably connected to the surrounding groove 13 on the rotating column 12, the fixed plate 1701 reciprocates within the cavity of the support member 2 under the combined constraint of the rotating column 12, the surrounding groove 13, and the sliding rod 17 during rotation. Furthermore, during the movement of the sliding rod 17, the sliding rod 17 carries the right-angle push rod 18... The lubricating oil is pushed in the transfer plug cylinder 19. As the pushing progresses, the lubricating oil is transferred to the required lubrication part through the transfer tube 22. It should be noted that during the process of the right-angle push rod 18 pushing the lubricating oil in the transfer plug cylinder 19, the right-angle push rod 18 will block the through hole 20 on the transfer plug cylinder 19, thereby preventing the lubricating oil in the lubricating oil tank 21 from entering the transfer plug cylinder 19 through the through hole 20. Only when the right-angle push rod 18 moves to the left side of the through hole 20 will the lubricating oil be replenished, waiting for the subsequent lubrication replenishment work.

[0050] Furthermore, through design, it can improve overall work efficiency; traditional lubrication methods require machine shutdown, which interrupts the production process. This equipment, however, can lubricate while the equipment is running, avoiding downtime and ensuring continuous production. Taking a metal pipe straightening production line as an example, if it would normally require a one-hour shutdown for lubrication, using the new equipment can reduce that hour of downtime losses, allowing the production line to continue outputting and significantly increasing output per unit time.

[0051] Reduced equipment wear: Insufficient lubrication at the fixed contact point between the roller shaft 3 and the component will lead to accelerated wear and shorten the equipment's lifespan. The new equipment provides timely and effective lubrication, reducing friction between components and minimizing wear. For example, the roller shaft 3, which previously required frequent replacement, can have its replacement cycle extended thanks to the newly designed lubrication system, reducing the cost of equipment maintenance and parts replacement.

[0052] Improved product quality: Stable lubrication ensures smooth rotation of roller 4, allowing for uniform force distribution on metal parts during straightening and conveying. For high-precision metal processing, such as aerospace component manufacturing, this avoids surface scratches and deformation caused by roller 4 jamming or uneven friction, improving dimensional accuracy and surface quality, and reducing the defect rate.

[0053] Furthermore, through its design, it can significantly reduce energy consumption and improve overall efficiency. The lubrication components are driven by the rotation of roller shaft 3, eliminating the need for an additional drive unit and avoiding extra energy consumption. In large-scale metal processing production, if many pieces of equipment use traditional lubrication systems with independent drives, the cumulative energy consumption will be enormous. This self-driving system reduces energy input at the source, aligning with the current trend of green and energy-saving industrial production. In the long run, it can save companies a significant amount of electricity costs.

[0054] Improving equipment reliability and stability: Reducing additional drive components also reduces potential points of failure. Drive components are often the most complex and prone to failure parts of the equipment; eliminating these components significantly improves the overall reliability and operational stability of the equipment.

[0055] Enhanced production flexibility and precision: Operators can flexibly increase lubrication frequency based on the straightening difficulty of metal parts or the degree of surface rust. When handling high-hardness, severely bent, or heavily rusted metal parts, timely increases in lubrication frequency ensure good contact between roller 4 and the metal part, preventing surface damage and poor conveying caused by excessive friction. Lubrication strategies can be quickly adjusted for different batches and characteristics of metal parts, meeting diverse production needs, improving production precision and efficiency, and resulting in more stable and reliable product quality.
