Description

Technical Field

[0001] This invention relates to the field of U-shaped tee machining technology, and in particular to a machining apparatus and machining method for U-shaped tees. Background Technology

[0002] A U-tee is a pipe fitting named for its U-shaped branches. When the branch is straight (a special U-tee), the angle between the main flow and the branch is usually 120°. It is mainly used in pipe systems to change the direction of fluid flow and achieve the function of diverting or merging flow. It is widely used in residential hot and cold water pipe systems, industrial water, and chemical transport.

[0003] Currently, during the processing of U-shaped tees, the connections between the inner and outer walls of the main channel and the branch channels, as well as the connections between the inner and outer walls of the two branch channels, are not rounded. Furthermore, the transitions between these connections are not smooth. This negatively impacts the structural strength of these connections, affecting the service life of the U-shaped tee. Additionally, it affects the flow velocity of the fluid at these connections. Summary of the Invention

[0004] To address the shortcomings of existing production technologies, the applicant provides a processing device and method for U-shaped tees. By improving the processing method of U-shaped tees, rounding is applied to the connection between the inner and outer walls of the main channel and the branch channel, as well as the connection between the inner and outer walls of the two branch channels, thereby increasing the service life of the entire U-shaped tee and improving the flow velocity of fluid at the connection between the inner walls of the main channel and the branch channel, as well as the connection between the inner walls of the two branch channels.

[0005] The technical solution adopted in this invention is as follows: A processing device for a U-shaped tee includes: a base, a conveying mechanism, a worktable, and a first processing mechanism, a second processing mechanism, a cutting mechanism, a first rounding mechanism, and a second rounding mechanism arranged sequentially along the U-axis. The worktable is mounted on the conveying mechanism, which drives the workpiece to move along the U-axis. The worktable carries the workpiece to be processed and drives the workpiece to rotate around the X-axis. The first processing mechanism and the second processing mechanism are used to process the inner and outer walls of the U-shaped tee, respectively. The cutting mechanism is used to cut the waste material after processing the outer wall of the U-shaped tee. The second rounding mechanism and the first rounding mechanism are used to round the corners at the connection between the main channel and the branch channel on the inner and outer walls of the U-shaped tee, and at the connection between two branch channels, respectively.

[0006] Therefore, by using a first rounding mechanism to achieve rounding of the outer wall of the U-shaped tee, and a second rounding mechanism to achieve rounding of the inner wall of the U-shaped tee, compared to the existing processing method of U-shaped tees without rounding, this processing method results in a smooth transition at the connection between the main channel and the branch channel, and at the connection between the two branch channels, on both the inner and outer walls of the U-shaped tee. This improves the structural strength of the connection between the main channel and the branch channel, and at the connection between the two branch channels, thereby increasing the service life of the entire U-shaped tee. Furthermore, during use, the smooth transition at the connection between the main channel and the branch channel, and at the connection between the two branch channels, increases the flow velocity of the fluid at these points. In addition, because the first processing mechanism, the second processing mechanism, the cutting mechanism, the first rounding mechanism, and the second rounding mechanism are arranged sequentially, the processing of the inner wall, the processing of the outer wall, the cutting of waste material, the rounding of the outer wall connection, and the rounding of the inner wall connection can be achieved sequentially, rather than all at once. After the inner wall is machined, the inner wall rounding operation is performed directly. This ensures that the U-shaped tee can be placed flat during the inner wall rounding operation, thus improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Furthermore, since the workpiece can rotate around the X-axis on the worktable, during the first and second rounding processes, the rotation of the workpiece in the X-axis direction avoids dead corners in the rounding, thereby further improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Moreover, by placing the cutting mechanism between the second processing mechanism and the first rounding mechanism, after the outer walls of the main channel and two branch channels of the U-shaped tee are machined, the waste material is cut off first, and then the rounding is performed. This allows for the removal of a large area of ​​waste material through cutting, and the rounding only needs to be performed on the required rounding locations (i.e., the connection between the main channel and the branch channels, and the connection between the two branch channels), thereby improving the processing efficiency and accuracy of the U-shaped tee.

[0007] As a further improvement to the above technical solution: the first processing mechanism includes a first processing section and a second processing section, the first processing section and the second processing section are distributed sequentially along the U-axis direction, and the first processing section and the second processing section have the same structure. The first processing section is parallel to the Z-axis, and the angle between the second processing section and the X-axis is 30°. The first processing section includes a first driving member, a second driving member and a first processing component. The driving end of the first driving member is connected to the second driving member, and the driving end of the second driving member is connected to the first processing component. The first driving member is used to drive the first processing component to move along the axial direction of the first driving member, and the second driving member is used to drive the first processing component to rotate along the axial direction of the second driving member. Thus, the first processing unit and the second processing unit can respectively realize the processing of the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee. During the processing of the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee, the first driving component and the second driving component are activated. The first driving component drives the first processing component to move along the axial direction of the first driving component to the side closer to the workpiece, and cooperates with the second driving component to drive the first processing component to rotate along the axial direction of the second driving component, so as to realize the processing of the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee.

[0008] As a further improvement to the above technical solution: the second processing mechanism includes a third processing section and a fourth processing section, the third processing section and the fourth processing section being distributed sequentially along the U-axis direction, and the third processing section and the fourth processing section having the same structure. The third processing section is parallel to the Z-axis, and the angle between the fourth processing section and the X-axis is 30°. The third processing section includes a third driving member, a fourth driving member, and a second processing member. The driving end of the third driving member is connected to the fourth driving member, and the driving end of the fourth driving member is connected to the second processing member. The third driving member is used to drive the second processing member to move along the axial direction of the third driving member, and the fourth driving member is used to drive the second processing member to rotate along the axial direction of the fourth driving member. Therefore, the third and fourth machining sections can respectively perform machining operations on the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee. During the machining process of the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee, the third and fourth driving components are activated. The third driving component drives the second machining component to move towards the side closer to the workpiece along the axial direction of the third driving component, and cooperates with the fourth driving component to drive the second machining component to rotate along the axial direction of the fourth driving component, so as to realize the machining operation of the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee.

[0009] As a further improvement to the above technical solution: the cutting mechanism includes a fifth driving member and a cutting member. The fifth driving member is connected to the base, and the driving end of the fifth driving member is connected to the cutting member. Thus, activating the fifth driving member drives the cutting member to move, and the cutting member acts on the workpiece to cut and remove waste material.

[0010] As a further improvement to the above technical solution: the first rounded corner mechanism includes a sixth driving member and a first rounded corner member. The driving end of the sixth driving member is connected to the first rounded corner member. The sixth driving member is used to drive the first rounded corner member to move along the axial direction of the sixth driving member. Thus, when the sixth driving member is activated, the first rounded corner member is driven to move towards the workpiece along the axial direction of the sixth driving member, so that the first rounded corner member abuts against the workpiece. With the cooperation of the worktable driving the workpiece to rotate around the X-axis, the rounded corner treatment is achieved at the connection between the main channel and the branch channel outer wall of the U-shaped tee, and at the connection between the outer walls of the two branch channels.

[0011] As a further improvement to the above technical solution: the second rounded corner mechanism includes a seventh driving member, an eighth driving member, and a second rounded corner member. The eighth driving member is connected to the driving end of the seventh driving member, and the second rounded corner member is connected to the driving end of the eighth driving member. The seventh driving member has an angle of 30° with the X-axis, and the eighth driving member is parallel to the Z-axis. The seventh driving member drives the second rounded corner member to move along the axial direction of the seventh driving member, and the eighth driving member drives the second rounded corner member to move along the axial direction of the eighth driving member. Thus, the seventh and eighth driving members are activated sequentially. First, the seventh driving member allows the eighth driving member and the second rounded corner member to be inserted into the U-shaped tee. Then, the eighth driving member allows the second rounded corner member to abut against the inner wall of the U-shaped tee. With the worktable driving the workpiece to rotate around the X-axis, rounded corner treatment is achieved at the connection between the inner wall of the U-shaped tee's flow channel and the inner wall of the branch channel, and at the connection between the inner walls of the two branch channels.

[0012] A processing method for a U-shaped tee includes the following steps: S1. Place the workpiece to be processed on the worktable; S2. The workpiece is transported to the bottom of the first processing mechanism by the conveying mechanism, and the workpiece is processed for the first time by the first processing mechanism to obtain the inner wall of the main channel of the U-shaped tee and the inner walls of the two branch channels. S3. The workpiece is transported to the area directly below the second processing mechanism by the conveying mechanism, and the workpiece is processed a second time by the second processing mechanism to obtain the outer wall of the main flow channel and the outer walls of the two branch channels of the U-shaped tee. S4. The workpiece is conveyed to the area directly below the cutting mechanism by the conveying mechanism, and the workpiece is cut by the cutting mechanism to remove waste material from the workpiece. S5. The workpiece is conveyed to the area directly below the first rounding mechanism by the conveying mechanism, and the workpiece is driven to rotate around the X-axis by the worktable to perform the first rounding treatment on the connection between the main channel and the outer wall of the branch channel, and the connection between the outer walls of the two branch channels. S6. The workpiece is conveyed to the area directly below the second rounded corner mechanism by the conveying mechanism, so that the second rounded corner mechanism is inserted into the workpiece. The workpiece is driven to rotate around the X-axis by the worktable to perform a second rounded corner treatment on the connection between the main channel and the inner wall of the branch channel, and the connection between the inner walls of the two branch channels, so as to obtain a U-shaped tee.

[0013] As a further improvement to the above technical solution, step S2 includes the following steps: S2-1. The workpiece is processed by the first processing unit to obtain the inner wall of the main channel of the U-shaped tee; S2-2. Rotate the workpiece 180° so that the opening of the main channel faces one side of the worktable along the Z-axis. S2-3. The workpiece is processed by the second processing unit to obtain the inner walls of the two branch channels of the U-shaped tee.

[0014] As a further improvement to the above technical solution, step S3 includes the following steps: S3-1. The workpiece is processed by the third processing unit to obtain the outer wall of the main channel of the U-shaped tee; S3-2. Rotate the workpiece 180° so that the opening of the main channel faces one side of the worktable along the Z-axis. S3-3. The workpiece is processed by the fourth processing unit to obtain the outer wall of the two branch channels of the U-shaped tee.

[0015] As a further improvement to the above technical solution: In S4, the cutting process is divided into three steps, and after each step, the workpiece needs to be rotated 120° along the U-axis; In S5, the first rounding process is divided into three steps, and after each step, the workpiece needs to be rotated 120° along the U-axis; In S6, the second rounding process is divided into three steps, and after each step, the workpiece needs to be rotated 120° along the U-axis.

[0016] The beneficial effects of this invention are as follows: This invention achieves rounded corner treatment on the outer wall of the U-shaped tee through a first rounded corner mechanism and on the inner wall through a second rounded corner mechanism. Compared to existing U-shaped tees without rounded corner treatment, this processing method results in a smooth transition at the connection points between the main flow channel and the branch flow channel on both the inner and outer walls, as well as at the connection points between the two branch flow channels. This improves the structural strength of these connections, thereby extending the overall service life of the U-shaped tee. Furthermore, during use, the smooth transition at these connections increases the fluid flow velocity. Additionally, the sequential arrangement of the first processing mechanism, the second processing mechanism, the cutting mechanism, the first rounded corner mechanism, and the second rounded corner mechanism allows for the sequential processing of the inner wall, outer wall, and waste material, as well as the rounding of the outer and inner wall connections, rather than all at once. After the inner wall is machined, the inner wall rounding operation is performed directly. This ensures that the U-shaped tee can be placed flat during the inner wall rounding operation, thus improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Furthermore, since the workpiece can rotate around the X-axis on the worktable, during the first and second rounding processes, the rotation of the workpiece in the X-axis direction avoids dead corners in the rounding, thereby further improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Moreover, by placing the cutting mechanism between the second processing mechanism and the first rounding mechanism, after the outer walls of the main channel and two branch channels of the U-shaped tee are machined, the waste material is cut off first, and then the rounding is performed. This allows for the removal of a large area of ​​waste material through cutting, and the rounding only needs to be performed on the required rounding locations (i.e., the connection between the main channel and the branch channels, and the connection between the two branch channels), thereby improving the processing efficiency and accuracy of the U-shaped tee.

[0017] The present invention also includes the following advantages: 1. The present invention can perform processing operations on the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee through the first processing unit and the second processing unit respectively; and can perform processing operations on the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee through the third processing unit and the fourth processing unit respectively.

[0018] 2. The present invention activates the sixth driving component, which drives the first rounded corner component to move along the axial direction of the sixth driving component towards the side closer to the workpiece, so that the first rounded corner component abuts against the workpiece. In conjunction with the worktable driving the workpiece to rotate around the X-axis, the rounded corner treatment is achieved at the connection between the main channel and the branch channel of the U-shaped tee and at the connection between the outer walls of the two branch channels.

[0019] 3. In this invention, the seventh and eighth driving components are activated sequentially. First, the seventh driving component is used to insert the eighth driving component and the second rounded corner component into the U-shaped tee. Then, the eighth driving component is used to make the second rounded corner component abut against the inner wall of the U-shaped tee. The workpiece is rotated around the X-axis by the working table to achieve the rounded corner treatment at the connection between the flow channel and the inner wall of the branch channel of the U-shaped tee, and at the connection between the inner walls of the two branch channels.

[0022] The specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0023] like Figures 1 to 12As shown, a processing device for a U-shaped tee includes: a base 1, a conveying mechanism 2, a worktable 3, and a first processing mechanism 4, a second processing mechanism 5, a cutting mechanism 6, a first rounding mechanism 7, and a second rounding mechanism 8 arranged sequentially along the U-axis. The worktable 3 is mounted on the conveying mechanism 2, which drives the workpiece to move along the U-axis. The worktable 3 carries the workpiece to be processed and drives the workpiece to rotate around the X-axis. The first processing mechanism 4 and the second processing mechanism 5 are used to process the inner and outer walls of the U-shaped tee, respectively. The cutting mechanism 6 is used to cut the waste material after processing the outer wall of the U-shaped tee. The second rounding mechanism 8 and the first rounding mechanism 7 are used to round the corners at the connection between the main channel and the branch channel on the inner and outer walls of the U-shaped tee, and at the connection between two branch channels, respectively. Therefore, the first rounding mechanism 7 achieves rounding of the outer wall of the U-shaped tee, and the second rounding mechanism 8 achieves rounding of the inner wall of the U-shaped tee. Compared with the existing processing method of U-shaped tees without rounding, this processing method results in a smooth transition at the connection between the main channel and the branch channel on both the inner and outer walls, as well as at the connection between the two branch channels. This improves the structural strength of the connection between the main channel and the branch channel on both the inner and outer walls, and at the connection between the two branch channels, thereby increasing the service life of the entire U-shaped tee. During use, the smooth transition at the connection between the main channel and branch channels on the inner and outer walls of the U-shaped tee, as well as at the connection between the two branch channels, increases the fluid flow velocity at these points. Furthermore, the sequential arrangement of the first processing mechanism 4, the second processing mechanism 5, the cutting mechanism 6, the first rounding mechanism 7, and the second rounding mechanism 8 allows for the sequential processing of the U-shaped tee's inner wall, outer wall, waste material cutting, rounding of the outer wall connection, and rounding of the inner wall connection, rather than... After the inner wall is machined, the inner wall rounding operation is performed directly. This ensures that the U-shaped tee can be placed flat during the inner wall rounding operation, thus improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Furthermore, since the workpiece can rotate around the X-axis on the worktable 3, during the first and second rounding processes, the rotation of the workpiece in the X-axis direction avoids dead corners in the rounding, thereby further improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Furthermore, the cutting mechanism 6 is set between the second processing mechanism 5 and the first rounding mechanism 7. After the outer walls of the main channel and two branch channels of the U-shaped tee are machined, the waste material is cut off first, and then the rounding is performed. In this way, the waste material can be removed over a large area by cutting off the waste material. When rounding, only the required rounding positions (i.e., the connection between the main channel and the branch channels, and the connection between the two branch channels) need to be rounded, thereby improving the processing efficiency and accuracy of the U-shaped tee.

[0024] In other words, since the included angle between the main channel and the branch channels of the U-shaped tee, as well as between the two branch channels, is 120°, if the inner wall is directly rounded after machining, the branch channels cannot act as a base for support because the workpiece (i.e., the blank) is a cuboid (i.e., the plane where the branch channel is located does not coincide with the plane where the workpiece is located). This will affect the accuracy of the inner wall rounding. The reason for rounding the inner wall last is that the remaining waste material from the U-shaped tee machining has been cut off. Whether the main channel or the branch channel acts as a base, it can remain horizontal without repeated adjustments. In this way, the machining efficiency and machining accuracy of the inner wall rounding of the U-shaped tee can be improved.

[0025] Specifically, such as Figure 10 , 11 As shown in Figure 12, the workbench 3 includes: a support plate 301, a rotating part 302, a carrier plate 303, and a clamping part 304. The support plate 301 is connected to the conveying mechanism 2, the rotating part 302 is connected to the support plate 301, the driving end of the rotating part 302 is connected to the carrier plate 303, and the clamping part 304 is installed on the side of the carrier plate 303 away from the rotating part 302. The rotating part 302 includes: a ninth driving member 305 and a rotating rod 306. The ninth driving member 305 is connected to the support plate 301. The ninth driving member 305 is connected to one end of the rotating rod 306, and the other end of the rotating rod 306 is rotatably connected to the support plate 301. The rotating rod 306 passes through the carrier plate 303 and is connected to the carrier plate 303. When the ninth driving member 305 is activated, the carrier plate 303 is rotated, thus enabling the workpiece to rotate around the X-axis. The clamping part 304 includes a pair of tenth driving members 307 and a clamping plate 308. The moving member 307 is connected to the clamping plate 308, and the tenth driving member 307 is connected to the carrier plate 303. The driving end of the tenth driving member 307 is connected to the clamping plate 308. The clamping plate 308 has a first groove 3081 and two second grooves 3082 on the side away from the tenth driving member 307. The two second grooves 3082 are located on both sides of the first groove 3081. The axial direction of the first groove 3081 is perpendicular to the XOU plane, and the axial direction of the second grooves 3082 is perpendicular to the XOU plane. The included angle between the surfaces is 30°. The plane where the clamping plate 308 is located is used for clamping the workpiece. The first groove 3081 is used to place the main channel of the U-shaped tee to clamp the workpiece using the main channel. The two second grooves 3082 are used to place the branch channels of the U-shaped tee to clamp the workpiece using the two branch channels. The tenth driving member 307 is activated, and the clamping plate 308 is moved by the tenth driving member 307 so that the two clamping plates 308 are brought closer to each other. In this way, the workpiece clamping operation can be realized.

[0026] For example, the conveyor mechanism 2 uses a conveyor belt, which is existing technology and will not be described in detail here; the ninth drive component 305 uses a motor, and the tenth drive component 307 uses a cylinder.

[0027] In this embodiment, the first processing mechanism 4 includes a first processing section 401 and a second processing section 402. The first processing section 401 and the second processing section 402 are distributed sequentially along the U-axis direction, and the first processing section 401 and the second processing section 402 have the same structure. The first processing section 401 is parallel to the Z-axis, and the angle between the second processing section 402 and the X-axis is 30°. The first processing section 401 includes a first driving member 403, a second driving member 404, and a first processing member 405. The driving end of the first driving member 403 is connected to the second driving member 404, and the driving end of the second driving member 404 is connected to the first processing member 405. The first driving member 403 is used to drive the first processing member 405 to move along the axial direction of the first driving member 403, and the second driving member 404 is used to drive the first processing member 405 to rotate along the axial direction of the second driving member 404. Thus, the processing of the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee can be realized by the first processing unit 401 and the second processing unit 402 respectively. During the processing of the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee, the first driving member 403 and the second driving member 404 are activated. The first driving member 403 drives the first processing member 405 to move towards the side closer to the workpiece along the axial direction of the first driving member 403, and cooperates with the second driving member 404 to drive the first processing member 405 to rotate along the axial direction of the second driving member 404, so as to realize the processing of the inner wall of the main channel and the inner wall of the branch channel of the U-shaped tee.

[0028] It should be noted that: the second processing unit 402 can be set up with one or two. When there is one, the production cost of the entire processing device can be reduced. The inner walls of the two branch channels need to be processed twice (after one is processed, the workpiece is rotated 180° along the Z-axis and then the other is processed). When there are two, the processing efficiency can be improved by processing the inner walls of the two branch channels at one time.

[0029] For example, the first driving component 403 is a cylinder, and the second driving component 404 is an electric motor.

[0030] In this embodiment, the second processing mechanism 5 includes a third processing section 501 and a fourth processing section 502. The third processing section 501 and the fourth processing section 502 are distributed sequentially along the U-axis direction, and the third processing section 501 and the fourth processing section 502 have the same structure. The third processing section 501 is parallel to the Z-axis, and the angle between the fourth processing section 502 and the X-axis is 30°. The third processing section 501 includes a third driving member 503, a fourth driving member 504, and a second processing member 505. The driving end of the third driving member 503 is connected to the fourth driving member 504, and the driving end of the fourth driving member 504 is connected to the second processing member 505. The third driving member 503 is used to drive the second processing member 505 to move along the axial direction of the third driving member 503, and the fourth driving member 504 is used to drive the second processing member 505 to rotate along the axial direction of the fourth driving member 504. Thus, the processing operations of the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee can be realized by the third processing unit 501 and the fourth processing unit 502 respectively. During the processing of the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee, the third driving member 503 and the fourth driving member 504 are activated. The third driving member 503 drives the second processing member 505 to move towards the side closer to the workpiece along the axial direction of the third driving member 503, and cooperates with the fourth driving member 504 to drive the second processing member 505 to rotate along the axial direction of the fourth driving member 504, so as to realize the processing operations of the outer wall of the main channel and the outer wall of the branch channel of the U-shaped tee.

[0031] It should be noted that the fourth processing unit 502 can be set up with one or two. When there is one, the production cost of the entire processing device can be reduced. The outer walls of the two branch channels need to be processed twice (after one is processed, the workpiece is rotated 180° along the Z-axis before processing the other). When there are two, the processing efficiency can be improved by processing the outer walls of the two branch channels at one time.

[0032] For example, the third drive component 503 uses a cylinder, and the fourth drive component 504 uses an electric motor.

[0033] In this embodiment, the cutting mechanism 6 includes a fifth driving member 601 and a cutting member 602. The fifth driving member 601 is connected to the base 1, and the driving end of the fifth driving member 601 is connected to the cutting member 602. Thus, the fifth driving member 601 is activated, driving the cutting member 602 to move and act on the workpiece to cut and remove waste material.

[0034] For example, the fifth drive unit 601 adopts a six-degree-of-freedom robot.

[0035] In this embodiment, the first rounded corner mechanism 7 includes a sixth driving member 701 and a first rounded corner member 702. The driving end of the sixth driving member 701 is connected to the first rounded corner member 702. The sixth driving member 701 is used to drive the first rounded corner member 702 to move along the axial direction of the sixth driving member 701. Thus, when the sixth driving member 701 is activated, the first rounded corner member 702 is driven to move along the axial direction of the sixth driving member 701 towards the side closer to the workpiece, so that the first rounded corner member 702 abuts against the workpiece. With the cooperation of the worktable 3 driving the workpiece to rotate around the X-axis, the rounded corner treatment is achieved at the connection between the main channel and the branch channel outer wall of the U-shaped tee, and at the connection between the outer walls of the two branch channels.

[0036] In this embodiment, the second rounded corner mechanism 8 includes: a seventh driving member 801, an eighth driving member 802, and a second rounded corner member 803. The eighth driving member 802 is connected to the driving end of the seventh driving member 801, and the second rounded corner member 803 is connected to the driving end of the eighth driving member 802. The angle between the seventh driving member 801 and the X-axis is 30°, and the eighth driving member 802 is parallel to the Z-axis. The seventh driving member 801 is used to drive the second rounded corner member 803 to move along the axial direction of the seventh driving member 801, and the eighth driving member 802 is used to drive the second rounded corner member 803 to move along the axial direction of the eighth driving member 802. Therefore, the seventh drive unit 801 and the eighth drive unit 802 are activated in sequence. First, the seventh drive unit 801 causes the eighth drive unit 802 and the second rounded corner piece 803 to be inserted into the U-shaped tee. Then, the eighth drive unit 802 causes the second rounded corner piece 803 to abut against the inner wall of the U-shaped tee. The workpiece is then rotated around the X-axis by the working table 3 to achieve the rounded corner treatment at the connection between the flow channel and the inner wall of the branch channel of the U-shaped tee, and at the connection between the inner walls of the two branch channels.

[0037] In this embodiment, the system further includes: multiple frames 9 connected to the base 1; the first processing unit 401 and the second processing unit 402 are both connected to the frames 9 (i.e., the first driving member 403 is connected to the frames 9); the third processing unit 501 and the fourth processing unit 502 are both connected to the frames 9 (i.e., the third driving member 503 is connected to the frames 9); and the sixth driving member 701 and the seventh driving member 801 are both connected to the frames 9.

[0038] like Figures 13 to 20 As shown, a processing method for a U-shaped tee includes the following steps: S1. Place the workpiece to be processed on the worktable 3; S2. The workpiece is transported to the bottom of the first processing mechanism 4 by the conveying mechanism 2, and the workpiece is processed for the first time by the first processing mechanism 4 to obtain the inner wall of the main channel of the U-shaped tee and the inner walls of the two branch channels. S3. The workpiece is transported to the bottom of the second processing mechanism 5 through the conveying mechanism 2, and the workpiece is processed a second time through the second processing mechanism 5 to obtain the outer wall of the main flow channel and the outer walls of the two branch channels of the U-shaped tee. S4. The workpiece is conveyed to the area directly below the cutting mechanism 6 by the conveying mechanism 2, and the workpiece is cut by the cutting mechanism 6 to remove the waste material of the workpiece. S5. The workpiece is conveyed to the area directly below the first rounding mechanism 7 by the conveying mechanism 2, and the workpiece is driven to rotate around the X-axis by the worktable 3 to perform the first rounding treatment on the connection between the main channel and the outer wall of the branch channel, and the connection between the outer walls of the two branch channels. S6. The workpiece is conveyed to the area directly below the second rounded corner mechanism 8 by the conveying mechanism 2, so that the second rounded corner mechanism 8 is inserted into the workpiece. The workpiece is driven to rotate around the X-axis by the worktable 3 to perform a second rounded corner treatment on the connection between the main channel and the inner wall of the branch channel, and the connection between the inner walls of the two branch channels, so as to obtain a U-shaped tee.

[0039] In this embodiment, S2 includes the following steps: S2-1. The workpiece is processed by the first processing unit 401 to obtain the inner wall of the main channel of the U-shaped tee. S2-2. Rotate the workpiece 180° so that the opening of the main channel faces one side of the worktable 3 along the Z-axis. S2-3. The workpiece is processed by the second processing unit 402 to obtain the inner walls of the two branch channels of the U-shaped tee.

[0040] In this embodiment, S3 includes the following steps: S3-1. The workpiece is processed by the third processing unit 501 to obtain the outer wall of the main channel of the U-shaped tee. S3-2. Rotate the workpiece 180° so that the opening of the main channel faces one side of the worktable 3 along the Z-axis. S3-3. The workpiece is processed by the fourth processing unit 502 to obtain the outer wall of the two branch channels of the U-shaped tee.

[0041] In this embodiment, in S4, the cutting process is divided into three steps, and after each step, the workpiece needs to be rotated 120° along the U-axis. In S5, the first rounding process is divided into three steps, and after each step, the workpiece needs to be rotated 120° along the U-axis. In S6, the second rounding process is divided into three steps, and after each step, the workpiece needs to be rotated 120° along the U-axis.

[0042] In summary, this invention achieves rounded corner treatment on the outer wall of the U-shaped tee through the first rounded corner mechanism 7 and on the inner wall of the U-shaped tee through the second rounded corner mechanism 8. Compared to existing U-shaped tees that do not undergo rounded corner treatment, this processing method results in a smooth transition at the connection between the main channel and the branch channel on both the inner and outer walls, as well as at the connection between the two branch channels. This improves the structural strength of the connection between the main channel and the branch channel on both the inner and outer walls, and at the connection between the two branch channels, thereby enhancing the overall usability of the U-shaped tee. In addition to extending the service life, the smooth transition between the main flow channel and the branch channel on the inner and outer walls of the U-shaped tee, as well as the connection between the two branch channels, during use improves the fluid flow velocity at these points. Furthermore, the sequential arrangement of the first processing mechanism 4, the second processing mechanism 5, the cutting mechanism 6, the first rounding mechanism 7, and the second rounding mechanism 8 allows for the sequential processing of the U-shaped tee's inner and outer walls, waste material cutting, rounding of the outer wall connection, and rounding of the inner wall connection. Instead of performing the inner wall rounding operation immediately after the inner wall processing is completed, this method ensures that the U-shaped tee can be placed flat during the inner wall rounding operation, thus improving the processing efficiency and accuracy of the U-shaped tee's inner wall rounding. Furthermore, since the workpiece can rotate around the X-axis on the worktable 3, during the first and second rounding processes, the rotation of the workpiece in the X-axis direction avoids dead corners in the rounding, thereby further improving the quality of the U-shaped tee. The processing efficiency and accuracy of rounding the inner wall corners are improved. Furthermore, the cutting mechanism 6 is set between the second processing mechanism 5 and the first rounding mechanism 7. After the outer walls of the main channel and two branch channels of the U-shaped tee are processed, the waste material is cut off first, and then the corners are rounded. In this way, the waste material can be removed over a large area by cutting off the waste material. When rounding the corners, only the required rounding corners need to be rounded (i.e., the connection between the main channel and the branch channels, and the connection between the two branch channels), so as to improve the processing efficiency and accuracy of the U-shaped tee.
