Description

Technical Field

[0001] This invention specifically relates to an oiling mechanism for a pipe cutting device. Background Technology

[0002] Pipe cutting equipment is used to cut pipes to a fixed length. In modern industrial production, pipe cutting is a common processing step. For reference, see the inventor's previous research on related equipment structures, such as patent number CN202110876664.4, "A Chipless Pipe End Cutting Machine and Pipe Processing Method." To improve cutting quality and efficiency while reducing tool wear, proper lubrication of the cutting tools is usually necessary. Traditional pipe cutting equipment mostly uses manual application or simple dripping devices for lubrication, but these methods have the following drawbacks: 1. Manual lubrication: Manual lubrication is not only time-consuming and labor-intensive, but it is also difficult to ensure that the lubricating oil is evenly distributed on the surface of the cutting tool, leading to unstable friction coefficients during cutting and affecting cutting accuracy and processing quality; 2. Dripping devices: Although dripping devices can achieve automated lubrication to a certain extent, their simple structure makes it impossible to accurately control the supply of lubricating oil according to the actual cutting situation, easily resulting in waste or insufficient lubricating oil. Furthermore, because the dripping position is relatively fixed, for high-speed rotating cutting wheels, the lubricating oil may not be accurately and continuously coated on the cutting wheel surface, causing significant material waste.

[0003] This invention was developed precisely because of the aforementioned shortcomings. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a convenient, efficient and oil-saving oiling mechanism for pipe cutting equipment.

[0005] The invention is achieved through the following technical solution:

[0006] An oiling mechanism for a pipe cutting device includes a base with a conveying channel for conveying pipes. The base also has a cutting wheel that can rotate around the axis of the conveying channel to cut the pipes circumferentially. The base has an oiling assembly, which includes an oil-seeping component and an oil supply pipe for conveying oil to the oil-seeping component. The oil-seeping component is located on the moving path of the cutting wheel and can contact the cutting wheel during its movement.

[0007] In the oiling mechanism of the pipe cutting equipment described above, the oil-permeating component is made of wool felt and is used to seal the outlet of the oil pipeline.

[0008] As described above, the oiling mechanism of the pipe cutting equipment includes a rotating disk connected to the base, the rotating disk being rotatably connected to the base with the conveying channel axis as the center, the cutting wheel being connected to the rotating disk, and several clamping wheels connected to the rotating disk. The cutting wheel and clamping wheels are circumferentially distributed with the conveying channel axis as the center. The base also has a first drive structure that can push the cutting wheel and clamping wheels toward or away from the center. The base also has a second drive structure that can drive the rotating disk to rotate.

[0009] As described above, the oiling mechanism of the pipe cutting equipment includes a conveying pipe seat on the base, a conveying channel on the conveying pipe seat, and a first driving structure including a swing block rotatably connected to a rotating disk, allowing the swing block to swing towards or away from the rotating disk. The cutting wheel and clamping wheel are individually connected to a swing block. A sliding sleeve that can slide relative to its axial direction is connected to the conveying pipe seat. The swing block is provided with a guide portion located on the moving path of the sliding sleeve, thereby enabling the swing block to swing when the sliding sleeve slides. The conveying pipe seat is also provided with a first driving device for pushing the sliding sleeve to slide.

[0010] As described above, the second driving structure of the pipe cutting equipment oiling mechanism includes a second driving device mounted on a base. The second driving device is connected to a transmission belt and can drive the transmission belt to transport along the length direction. The conveying pipe seat is provided with a rotating sleeve that can rotate relative to it in the circumferential direction. The rotating sleeve is connected to a rotating disk, and the transmission belt is wound around the rotating sleeve.

[0011] As described above, the oiling mechanism of the pipe cutting equipment has a cutting wheel and two clamping wheels connected to the rotating disk.

[0012] In the oiling mechanism of the pipe cutting equipment described above, the cutting wheel and clamping wheel are evenly distributed on the rotating disk along the circumferential direction.

[0013] As described above, the oiling mechanism of the pipe cutting equipment has multiple conveying pipe seats on the base, each conveying pipe seat has a corresponding conveying channel, and each conveying pipe seat is connected to a rotating disk. The multiple conveying pipe seats are distributed linearly, and the oil seepage component is long and strip-shaped with its length direction consistent with the distribution direction of the conveying pipe seats.

[0014] As described above, in the pipe cutting equipment oiling mechanism, the base is provided with a collection frame below the rotating disk for collecting the cut pipes.

[0015] As described above, the oiling mechanism of the pipe cutting equipment has an oil drain port on the collection frame for discharging oil.

[0016] Compared with existing technologies, the invention has the following advantages:

[0017] The oiling mechanism of the pipe cutting equipment of the present invention wraps the pipe with a matching groove, and then the punch head passes through the punch hole of the matching groove to realize the drilling of the inner side of the pipe bend in the matching groove. It can accurately set the drilling position and realize the precise drilling function. At the same time, the groove wall of the matching groove restricts the deformation of the pipe, making it difficult for the pipe cross-section to deform, thereby preventing deformation during the drilling process and affecting the processing accuracy. The drilling mechanism of this solution has a simple structure, is easy to operate, and improves the processing efficiency. In order to improve the accuracy, the oiling mechanism of the pipe cutting equipment of the present invention also has a clamping structure for pressing the pipe into the matching groove. A mating groove 81 is provided on the side of the clamping block near the positioning mold. The mating groove and the matching groove close together to form a channel that matches the shape of the pipe. In this way, the pipe is restricted in the channel near the drilling position, making it extremely difficult for it to undergo radial deformation during the drilling process, ensuring that the shape is not changed during the processing, and preventing defects such as material deformation and cracking during the drilling process, thus ensuring the processing accuracy and product quality.

[0018] The oiling mechanism of the pipe cutting equipment of the present invention is to set an oiling component on the pipe cutting equipment. The oiling component delivers oil through an oil supply pipe to keep the oil-soaked parts continuously wetted with oil. In this way, the cutting wheel can continuously and evenly contact the oil-soaked parts during the operation of the equipment. During the process, oil can be continuously and evenly applied to the cutting wheel without stopping the machine, which improves efficiency and avoids material waste caused by excessive oil loss, thus saving production costs.

[0019] The oil-absorbing component of this invention is wool felt. Compared with other materials such as sponge, using wool felt as an oil-absorbing component has advantages such as excellent oil absorption performance, high durability, strong temperature adaptability, and easy cleaning and maintenance.

[0024] The invention will be further described below with reference to the accompanying drawings:

[0025] The orientations described in the invention specification, such as "up," "down," "left," "right," "front," and "back," are based on the orientations in the accompanying drawings and are intended to facilitate the description of the relationships between the various components. They do not indicate the unique or absolute positional relationships between the various components, but are merely one embodiment of the invention and are not a limitation on its implementation.

[0026] like Figure 1 As shown, this embodiment provides an oiling mechanism for a pipe cutting device, including a base 1. The base 1 is provided with a conveying channel 10 for conveying pipes. The base 1 is also provided with a cutting wheel 21 that can rotate around the axis of the conveying channel 10 and cut the pipes circumferentially. The base 1 is provided with an oiling assembly 3, which includes an oil-permeating component 31 and an oil supply pipe 32 for supplying oil to the oil-permeating component 31. The oil-permeating component 31 is located on the moving path of the cutting wheel 21 and can contact the cutting wheel 21 during its movement. The cutting wheel 21 is brought into contact with the oil-permeable part 31 during its circumferential rotation. Preferably, the oil-permeable part 31 is made of a soft material, allowing the cutting wheel 21 to penetrate into the oil-permeable part 31 when in contact with it. Oil is delivered through the oil pipe 32, keeping the oil-permeable part 31 continuously wetted with oil. This ensures that oil is continuously and evenly applied to the cutting wheel 21 during equipment operation without requiring machine downtime, improving efficiency and preventing excessive oil loss that would lead to material waste, thus saving production costs.

[0027] As a preferred embodiment, such as Figures 1 to 3As shown, the oil-absorbing component 31 is made of wool felt, but other materials capable of absorbing liquids, such as sponges, can also be used. Using wool felt as the oil-absorbing component has several significant advantages over using sponges or other materials: Excellent oil absorption: Wool felt has excellent oil absorption capacity, capable of absorbing a large amount of lubricating oil in a short time and maintaining a stable oil supply for a long time; in comparison, materials such as sponges may be slightly inferior in terms of oil absorption and stability; High durability: Wool felt has good wear resistance and can maintain good oil absorption and release performance even after long-term use; materials such as sponges may wear or deform after a period of use, thus affecting their oil absorption effect; Strong temperature adaptability: Wool felt can maintain its physical properties over a wide temperature range. The wool felt material is suitable for use in various working environments; some sponge materials may experience performance degradation under high or low temperatures, affecting their normal use; it is easy to clean and maintain: wool felt can maintain its performance through simple cleaning or replacement, facilitating daily maintenance; some sponge materials may be difficult to clean thoroughly after use, accumulating impurities over time and affecting their function; it adapts to oils of different viscosities: wool felt has good adaptability to lubricating oils of different viscosities, is not prone to clogging, and can ensure a stable oil supply; sponge and other materials may experience clogging when faced with high-viscosity lubricating oils; it is economical: although the initial cost of wool felt may be slightly higher than some sponge materials, considering its longer service life and better performance, it is more economical overall. Furthermore, using wool felt as the material for the oil-permeable part 31 allows for the automatic cutting of a kerf that matches the blade edge during the movement of the cutting wheel 21. Figure 3 As shown, the oil leakage part 31 can be sealed at the outlet of the oil pipeline 32.

[0028] Preferably, a rotating disk 22 is connected to the base 1, and the rotating disk 22 is rotatably connected to the base 1 with the axis of the conveying channel 10 as the center. The cutting wheel 21 is connected to the rotating disk 22, and a plurality of clamping wheels 23 are connected to the rotating disk 22. The cutting wheel 21 and the clamping wheels 23 are circumferentially distributed with the axis of the conveying channel 10 as the center. The base 1 is also provided with a first driving structure 201 that can push the cutting wheel 21 and the clamping wheels 23 toward or away from the center. The base 1 is also provided with a second driving structure 202 that can drive the rotating disk 22 to rotate. Preferably, one cutting wheel 21 and two clamping wheels 23 are connected to the rotating disk 22. The cutting wheel 21 and the clamping wheels 23 are evenly distributed on the rotating disk 22 along the circumferential direction, so that the clamping force is more uniform and stable when clamping the pipe.

[0029] To be more specific, such as Figure 3 and Figure 4As shown, the base 1 is provided with a conveying tube seat 2, the conveying channel 10 is provided on the conveying tube seat 2, the first driving structure 201 includes a swing block 24 rotatably connected to the rotating disk 22, so that the swing block 24 can swing towards or away from the rotating disk 22. The middle part of the swing block 24 is rotatably connected to the rotating disk 22, and the swing block 24 can approach the conveying channel 10 when swinging. The cutting wheel 21 and the clamping wheel 23 are individually connected to a swing block 24. The conveying tube seat 2 is connected with a sliding sleeve 25 that can slide relative to its axial direction. The swing block 24 is provided with a guide part 241 located on the moving path of the sliding sleeve 25. The guide part 241 is outwardly protruding and has an inclined surface, so that the sliding sleeve 25 can push the swing block 24 to swing when sliding. The conveying tube seat 2 is also provided with a first driving device 26 for pushing the sliding sleeve 25 to slide. Figure 3 and Figure 4 As shown, the first driving device 26 pushes the sliding sleeve 25 to slide left and right. When the sliding sleeve 25 slides to the right, the left end of the sliding sleeve 25 abuts against the guide part 241 of the swing block 24, thereby pushing the swing block 24 to swing towards the conveying channel 10, so that the cutting wheel 21 and the clamping wheel 23 connected to the swing block 24 move closer to the conveying channel 10, thereby abutting against the pipe output from the conveying channel 10. Due to the continuous rotation of the rotating disk 22, the cutting wheel 21 and the clamping wheel 23 clamp the pipe and rotate around the circumference of the pipe, thereby achieving cutting or cutting a slit. When the sliding sleeve 25 slides to the left, due to the continuous rotation of the rotating disk 22, the swing block 24 naturally returns to its original position under the action of centrifugal force.

[0030] To be more specific, such as Figure 2 As shown, the second driving structure 202 includes a second driving device 4 mounted on the base 1. The second driving device 4 is connected to a transmission belt 41 and can drive the transmission belt 41 to transport along its length. The conveying tube seat 2 is provided with a rotating sleeve 27 that can rotate relative to it in the circumferential direction. The rotating sleeve 27 is connected to the rotating disk 22. The transmission belt 41 is wound around the rotating sleeve 27. When the output shaft of the second driving device 4 rotates, it drives the transmission belt 41 to drive, the transmission belt 41 drives the rotating sleeve 27 to rotate, and the rotating sleeve drives the rotating disk 22 to rotate continuously. Figure 2 and Figure 3 As shown, to increase the friction between the rotating disk 22 and the transmission belt 41, a rubber sleeve 28 for increasing friction can be fitted onto the rotating disk 22. In this embodiment, multiple conveying pipe seats 2 are arranged side by side, and each conveying pipe seat 2 is connected to a corresponding rotating sleeve 27. In order to ensure that the transmission belt 41 has a considerable tension at each rotating sleeve 27, the transmission belt 41 can be wound in a serpentine manner around each rotating sleeve 27, resulting in a compact structure and high working efficiency.

[0031] As a preferred option, such as Figure 1 and Figure 2 As shown, the base 1 is provided with multiple conveying pipe seats 2, each conveying pipe seat 2 is provided with a corresponding conveying channel 10, and each conveying pipe seat 2 is connected to a rotating disk 22. The multiple conveying pipe seats 2 are distributed linearly. The oil seepage component 31 is long and strip-shaped and its length direction is consistent with the distribution direction of the conveying pipe seats 2. This makes the structure compact and can apply oil more evenly to each cutting wheel 21.

[0032] As a preferred option, such as Figure 1 and Figure 3 As shown, the base 1 is provided with a collection frame 5 for collecting the cut pipes below the rotating disk 22; the collection frame 5 is provided with an oil drain port 51 for draining oil, thereby enabling the collection of the cut pipes and the collection of excess oil.
