Description

Technical Field

[0001] This utility model relates to the technical field of quick-descent rods for aluminum band saws, and in particular to a high-precision quick-descent rod for aluminum band saws with an internal water-cooling pipe. Background Technology

[0002] In the metal processing industry, band saws are commonly used equipment for cutting metal materials, and their sawing accuracy and efficiency are crucial for production quality and cost control. High-precision aluminum band saw quick-descent levers play a key role in the band saw's operation, responsible for rapidly lowering the saw blade to the cutting position, directly affecting the initial sawing accuracy and efficiency. Their applications cover various metal processing workshops for cutting metal materials. Currently, high-precision aluminum band saw quick-descent levers typically require the following technologies in practical applications:

[0003] 1. Precision guiding technology: Ensures that the quick-release lever maintains straightness during its up-and-down movement, enabling the saw blade to accurately reach the cutting position and improve sawing accuracy;

[0004] 2. Stable support technology: Provides stable support for the fast descent bar, ensuring that it does not sway during rapid descent and cutting, and maintaining cutting stability;

[0005] 3. High-efficiency cooling technology: Effectively cools the saw blade and workpiece during the sawing process, reduces temperature, reduces saw blade wear, and improves sawing quality and saw blade life.

[0006] Currently, there are various types of quick-descent bars for band saws on the market. Some traditional quick-descent bars use a simple linear guide structure to guide the up and down movement.

[0007] However, the above method has a prominent problem: in the existing technology, the connection between the quick-descent bar and the iron plate is guided by a guide rail. However, the guide rail structure needs to leave a certain gap for sliding. The gap is relatively large. When sawing large-diameter materials, the quick-descent bar is stuck by the gap, making the descent unsmooth. In addition, the water pipes in the existing technology are all external. In order to ensure the stability of their external placement, their diameter is usually relatively small, which leads to low water output and an unsightly appearance. Summary of the Invention

[0008] To address the shortcomings of existing technologies, this utility model provides a high-precision aluminum band saw quick-descent bar with an integrated water-cooling pipe. This solves the problems of existing technologies where the quick-descent bar connects iron plates using a guide rail system, but the guide rail structure requires a certain gap for sliding. This gap is relatively large, causing the quick-descent bar to become stuck when sawing large-diameter materials, resulting in an unsmooth descent. Furthermore, existing technologies use externally mounted water pipes, and to ensure their stability, their diameter is usually relatively small, leading to low water output and an unsightly appearance.

[0009] To achieve the above objectives, this utility model provides the following technical solution:

[0010] A high-precision aluminum band saw quick-descent bar with built-in water-cooling pipe includes a U-shaped base. The U-shaped base has four bearings installed inside, which are symmetrically arranged about the center of the U-shaped base. An aluminum connecting rod is slidably connected inside the U-shaped base. All four bearings are in contact with the outer surface of the aluminum connecting rod. A water outlet pipe is sleeved inside the aluminum connecting rod.

[0011] Preferably, the upper end of the aluminum connecting rod is provided with an upper plate, and the water outlet pipe is located inside the upper plate.

[0012] Preferably, the upper plate is internally threaded with countersunk bolts, which are threaded inside the aluminum connecting rod.

[0013] Preferably, the lower end of the aluminum connecting rod is provided with a lower plate.

[0014] Preferably, the lower plate is internally threaded with a fixing bolt, which is threaded inside the aluminum connecting rod.

[0015] Preferably, the lower plate has a set of water outlets inside, and the water outlet pipes are all on the same vertical line as the set of water outlets.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] First, the low-friction characteristics of the bearings allow the aluminum connecting rod to move smoothly and stably up and down within its square center. This design not only ensures the straightness of the aluminum connecting rod's movement but also greatly reduces resistance during the movement, enabling the quick-descent bar to descend rapidly and accurately, meeting the high-efficiency sawing requirements of the band saw. The water outlet pipe, internally fitted into the aluminum connecting rod, connects at one end to an external cooling water supply system. Cooling water enters the water outlet pipe under pressure. Because the water outlet pipe is built into the aluminum connecting rod, it is well protected and not easily damaged by external impacts, effectively extending its service life.

[0018] Second, the entire quick-descent bar adopts a modular assembly method, with each component connected by bolts and other fasteners to form a whole. This design makes the quick-descent bar more convenient in terms of installation, disassembly, and maintenance. For example, when it is necessary to replace the water outlet pipe, simply unscrew the countersunk bolts on the upper plate and the fixing bolts on the lower plate to separate the aluminum connecting rod from the upper and lower plates, thus making it easy to remove and replace the water outlet pipe. Similarly, if the bearing has problems such as wear, it can also be relatively easy to disassemble and replace it from the U-shaped base, which greatly improves the maintenance efficiency of the equipment and reduces maintenance costs.

[0025] This application provides a high-precision aluminum band saw quick-descent bar with an internal water-cooling pipe. This effectively solves the problems of existing quick-descent bars where the connection between the iron plates uses a guide rail, which requires a certain gap for sliding. This gap is relatively large, causing the quick-descent bar to become stuck when sawing large-diameter materials, resulting in an unsmooth descent. Furthermore, existing water pipes are externally mounted, and to ensure their stability, their diameter is usually relatively small, leading to low water output and an unsightly appearance. The low-friction characteristics of the bearings allow the aluminum connecting rod to move smoothly and stably within its square center. This design not only ensures the straightness of the aluminum connecting rod's movement but also significantly reduces resistance during movement, enabling the quick-descent bar to descend quickly and accurately, meeting the high-efficiency sawing requirements of the band saw. The water outlet pipe, internally sleeved within the aluminum connecting rod, connects to an external cooling water supply system at one end. Cooling water enters the outlet pipe under pressure. Because the outlet pipe is built into the aluminum connecting rod, it is well protected and less susceptible to damage from external impacts, effectively extending its service life. Example

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the problem that in the prior art, the connection between the quick-descent bar and the iron plate adopts a guide rail form, but the guide rail structure needs to leave a certain gap for sliding. The gap is relatively large, and when sawing large-diameter materials, the quick-descent bar is stuck by the gap, making the descent unsmooth. In addition, the water pipes in the prior art are all externally placed. In order to ensure the stability of their external placement, their diameter is usually relatively small, resulting in low water output and an unsightly appearance. The overall idea is as follows: a high-precision aluminum band saw quick-descent bar with a built-in water-cooled pipe, including a U-shaped base 11, four bearings 12 are set inside the U-shaped base 11, the four bearings 12 are symmetrically arranged with the center of the U-shaped base 11 as the axis, and an aluminum connecting rod 13 is slidably connected inside the U-shaped base 11. The four bearings 12 are all in contact with the outer surface of the aluminum connecting rod 13. First, the U-shaped base 11 is securely installed on the band saw at the designated position by tightening bolts, serving as the support foundation for the entire quick-descent rod and ensuring its stability during operation. The aluminum connecting rod 13 is located at the center of a square formed by four bearings 12 symmetrically arranged around the center of the U-shaped base 11, and is in close contact with the surfaces of the four bearings 12. Due to the low friction characteristics of the bearings 12, the aluminum connecting rod 13 can move smoothly and stably up and down within this square center. This design not only ensures the straightness of the movement of the aluminum connecting rod 13, but also greatly reduces the resistance during the movement, enabling the quick-descent rod to descend quickly and accurately, meeting the high-efficiency sawing requirements of the band saw. At the same time, the aluminum connecting rod 13 is made of aluminum, which reduces its weight while ensuring structural strength, further optimizing the quick-descent performance.

[0027] An outlet pipe 14 is sleeved inside the aluminum connecting rod 13. An upper plate 15 is provided at the upper end of the aluminum connecting rod 13, and the outlet pipe 14 is located inside the upper plate 15. One end of the outlet pipe 14 sleeved inside the aluminum connecting rod 13 is connected to an external cooling water supply system. Cooling water enters the outlet pipe 14 under pressure. Since the outlet pipe 14 is built into the aluminum connecting rod 13, it is well protected and not easily damaged by external collisions or other factors, effectively extending its service life. The outlet pipe 14 extends into the upper plate 15 and is sealed to the external water source through the upper plate 15 to ensure that the cooling water does not leak.

[0028] The upper plate 15 is internally threaded with countersunk bolts 16, which are threaded into the aluminum connecting rod 13. A lower plate 17 is located at the lower end of the aluminum connecting rod 13, and a fixing bolt 18 is internally threaded into the lower plate 17, also threaded into the aluminum connecting rod 13. A set of water outlets 19 is provided inside the lower plate 17. The water outlet pipes 14 are aligned vertically with the set of water outlets 19. When the aluminum connecting rod 13 descends to the sawing position, the cooling water in the water outlet pipes 14 flows down the pipes and aligns with the set of water outlets 19 on the lower plate 17. Because the water outlet pipes 14 and the set of water outlets 19 are aligned vertically, the cooling water can accurately flow out from the water outlets 19 and directly spray onto the contact area between the saw blade and the workpiece, where the cooling water provides both cooling and lubrication. The dual-function design reduces the high temperature generated during sawing and decreases friction between the saw blade and the workpiece, thereby improving sawing stability and precision and extending the service life of the saw blade. The entire quick-release bar adopts a modular assembly method, with each component connected by bolts and other connectors to form a whole. This design makes the quick-release bar easier to install, disassemble, and maintain. For example, when it is necessary to replace the water outlet pipe 14, simply unscrew the countersunk bolts 16 of the upper plate 15 and the fixing bolts 18 of the lower plate 17 to separate the aluminum connecting rod 13 from the upper and lower plates 17, thus making it easy to remove and replace the water outlet pipe 14. Similarly, if the bearing 12 has problems such as wear, it can also be relatively easy to disassemble and replace from the U-shaped base 11, greatly improving the maintenance efficiency of the equipment and reducing maintenance costs.

[0029] To address the problems existing in the prior art, this utility model provides a high-precision aluminum band saw quick-descent rod with a built-in water-cooled pipe. The low-friction characteristics of the bearing 12 allow the aluminum connecting rod 13 to move smoothly and stably up and down within its square center. This design not only ensures the straightness of the aluminum connecting rod 13's movement but also significantly reduces resistance during movement, enabling the quick-descent rod to descend quickly and accurately, meeting the high-efficiency sawing requirements of the band saw. The water outlet pipe 14, internally sleeved within the aluminum connecting rod 13, connects at one end to an external cooling water supply system. Cooling water enters the water outlet pipe 14 under pressure. Because the water outlet pipe 14 is built into the aluminum connecting rod 13, it is well protected and less susceptible to damage from external impacts, effectively extending its service life.

[0030] Working principle:

[0031] The first step involves using the U-shaped base 11 as the fundamental support structure for the entire quick-descent bar. The U-shaped design provides installation space for the internal components. Four bearings 12 are symmetrically arranged inside the U-shaped base 11, with the center as the axis, providing guidance and support for the up-and-down sliding of the aluminum connecting rod 13, ensuring the stability and accuracy of the aluminum connecting rod 13 during movement. The U-shaped base 11 is installed and fixed to the corresponding position on the band saw by tightening bolts, connecting the entire quick-descent bar to the band saw as a whole. The four bearings 12 are evenly and symmetrically distributed inside the U-shaped base 11, and they are tightly fitted to the outer surface of the aluminum connecting rod 13. The function of the bearings 12 is to reduce the frictional force when the aluminum connecting rod 13 slides, allowing the aluminum connecting rod 13 to move freely within the U-shaped base 11. The aluminum connecting rod 13 moves smoothly up and down within the band saw, ensuring its straightness and stability during movement, thereby improving the sawing accuracy of the band saw. The aluminum connecting rod 13 not only performs the up-and-down movement function but also provides internal space for the water outlet pipe 14. Aluminum material is lightweight and high-strength, meeting the rapid descent requirements of the quick-descent rod while ensuring structural stability. The aluminum connecting rod 13 is connected to the upper plate 15 via countersunk bolts 16 and to the lower plate 17 via fixing bolts 18. The upper plate 15, lower plate 17, and the internal water outlet pipe 14 are combined into a single unit, realizing the various functions of the quick-descent rod. The water outlet pipe 14 is designed with... Inside the aluminum connecting rod 13, this built-in design protects the water outlet pipe 14 from damage by external factors and makes the overall quick-descent rod more aesthetically pleasing. One end of the water outlet pipe 14 connects to an external water source, and the other end is aligned with a set of water outlets 19 on the lower plate 17, delivering cooling water to the sawing area for cooling and lubrication, further improving the stability and precision of the sawing. The upper plate 15 is connected to the upper end of the aluminum connecting rod 13 by countersunk bolts 16. The countersunk bolt 16 is designed so that the bolt head is recessed into the upper plate 15, without affecting the flatness of the upper plate 15 surface, while ensuring the connection between the upper plate 15 and the aluminum connecting rod 13. To ensure its stability, the upper plate 15 may be connected to other drive components of the band saw, providing a power source for the up-and-down movement of the aluminum connecting rod 13. The lower plate 17, fixing bolts 18, and water outlet 19: The lower plate 17 is fixedly connected to the lower end of the aluminum connecting rod 13 by fixing bolts 18. The fixing bolts 18 ensure that the connection between the lower plate 17 and the aluminum connecting rod 13 is stable and reliable. A set of water outlets 19 opened on the lower plate 17 is on the same vertical line as the water outlet pipe 14. The cooling water in the water outlet pipe 14 can flow out smoothly through the water outlets 19 and directly act on the sawing part to achieve cooling and lubrication of the saw blade and the workpiece, ensuring the smooth progress of the sawing work.

[0032] The second step involves first securely installing the U-shaped base 11 at the designated position on the band saw using screws. This serves as the supporting foundation for the entire quick-descent rod, ensuring its stability during operation. The aluminum connecting rod 13 is located at the center of a square formed by four bearings 12 symmetrically positioned around the center of the U-shaped base 11, and is in close contact with the surfaces of the four bearings 12. Due to the low-friction characteristics of the bearings 12, the aluminum connecting rod 13 can achieve smooth and stable up-and-down movement within this square center. This design not only ensures the straightness of the movement of the aluminum connecting rod 13 but also greatly reduces resistance during movement. The force allows the quick-descent bar to descend rapidly and accurately, meeting the high-efficiency sawing requirements of the band saw. Meanwhile, the aluminum connecting rod 13, made of aluminum, reduces its weight while maintaining structural strength, further optimizing the quick-descent performance. An outlet pipe 14, internally sleeved within the aluminum connecting rod 13, connects at one end to an external cooling water supply system. Cooling water enters the outlet pipe 14 under pressure. Because the outlet pipe 14 is built into the aluminum connecting rod 13, it is well protected and less susceptible to damage from external impacts, effectively extending its service life. The outlet pipe 14 extends into the upper plate 15 and passes through the upper plate 15... A sealed connection is established with the external water source to ensure no cooling water leakage. When the aluminum connecting rod 13 descends to the sawing position, the cooling water in the outlet pipe 14 flows down the pipe and aligns with a set of outlets 19 on the lower plate 17. Since the outlet pipe 14 and the set of outlets 19 are on the same vertical line, the cooling water can flow accurately from the outlets 19 and spray directly onto the contact area between the saw blade and the workpiece. The cooling water plays a dual role of cooling and lubrication here, reducing the high temperature generated during sawing, reducing friction between the saw blade and the workpiece, thereby improving the stability and accuracy of sawing, and extending the service life of the saw blade. The quick-descent bar adopts a modular assembly method, with each component connected by bolts and other fasteners to form a whole. This design makes the quick-descent bar easier to install, disassemble, and maintain. For example, when the outlet pipe 14 needs to be replaced, simply unscrew the countersunk bolts 16 of the upper plate 15 and the fixing bolts 18 of the lower plate 17 to separate the aluminum connecting rod 13 from the upper and lower plates 17, thus making it easy to remove and replace the outlet pipe 14. Similarly, if the bearing 12 has problems such as wear, it can also be relatively easy to remove and replace from the U-shaped base 11, which greatly improves the maintenance efficiency of the equipment and reduces maintenance costs.

[0033] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
