Description

Technical Field

[0001] The present invention relates to the technical field of pipe fitting processing, and specifically relates to a PE tee pipe fitting end face processing device. Background Art

[0002] In the production and processing field of PE (polyethylene) tee pipe fittings, end face punching is a key process to form a tee structure and achieve fluid diversion. Traditional PE tee pipe fitting end face processing devices usually adopt the method of mechanical fixation and external punching. Specifically, the device horizontally or vertically fixes the pipe fitting on the processing platform through a mechanical fixture, and uses an external drill bit or laser cutting device to perform punching operations on the end face of the pipe fitting. This technology meets the basic production requirements to a certain extent, but there are obvious deficiencies in dealing with thin-walled pipe fittings, ensuring processing accuracy, and improving production efficiency.

[0003] 1. Deformation and collapse problems of thin-walled pipe fittings: Due to the relatively low rigidity and high elasticity of the PE material itself, thin-walled pipe fittings are extremely prone to deformation or collapse under the action of the punching force applied externally. Especially during the punching process, the inner wall is prone to inward depression due to uneven pressure, resulting in the aperture not meeting the design requirements, or even directly scrapping the pipe fitting. This not only increases the waste of raw materials but also significantly reduces production efficiency.

[0004] 2. Processing errors caused by insufficient stability of pipe fittings: Traditional devices mainly rely on external fixtures to fix pipe fittings, and it is difficult to achieve effective all-round restraint in the vertical and horizontal directions. During the punching process, the pipe fitting may shake or displace due to vibration, impact, or its own gravity, resulting in processing errors such as hole position deviation and uneven aperture. These problems not only affect product quality but also increase the subsequent rework cost. Summary of the Invention

Four connecting rods are fixedly connected between the fixing rod and the connecting rod. A sliding sleeve is slidably connected to the outer wall of the connecting rod. A moving rod is fixedly connected to one side of the sliding sleeve.

[0009] As a further preference of this technical solution, a second cylinder is fixedly installed on the sliding plate. The output end of the second cylinder is fixedly connected to a slider slidably installed on the fixing rod. Four push rods are rotatably connected to the outer periphery of the slider wall. The other end of the push rod is rotatably connected to the sliding sleeve.

[0010] As a further preference of this technical solution, a rectangular groove is opened on the surface of the sliding plate. A third cylinder fixedly installed on the rack is arranged above the sliding plate. The output end of the third cylinder is fixedly connected to a lifting plate. An arc-shaped rod is fixedly connected to the side wall of the lifting plate. A swing plate rotatably installed on the lifting plate is slidably connected to the arc-shaped rod. And the swing plate corresponds to the position of the rectangular groove. A fourth damping spring and a blocking rod are respectively arranged on both sides of the swing plate. The fourth damping spring is sleeved on the arc-shaped rod. The blocking rod is fixedly installed on the lifting plate. A push plate is fixedly connected to the side wall of the swing plate.

[0011] As a further preference of this technical solution, a mounting block is fixedly installed on the fixing frame. A trapezoidal block is slidably connected to the mounting block. One end of the trapezoidal block is fixedly connected to the second support frame. The other end of the trapezoidal block is fixedly connected to a limit block adapted to the push plate. And a second damping spring sleeved on the sliding rod is arranged between the limit block and the mounting block.

[0012] As a further preference of this technical solution, a connecting plate is fixedly connected to the outside of the sliding plate. First damping springs are fixedly connected to both sides of the connecting plate. The other ends of the first damping springs are provided with fixing blocks fixedly installed on the fixing frame.

[0013] As a further preference of this technical solution, a trapezoidal block is fixedly connected to the inside of the sliding plate. Vertical rods fixedly installed on the fixing frame are arranged on both sides of the trapezoidal block. A mounting plate fixedly connected to the first support frame is slidably connected to the vertical rods. A third damping spring sleeved on the vertical rods is arranged on the top of the mounting plate.

[0014] As a further preferred embodiment of the present technical solution, the conveying assembly includes a driving motor fixedly mounted on one side of the frame, a rotating shaft is rotatably arranged on both sides of the frame, and the output end of the driving motor is fixedly connected to the rotating shaft, the outer wall of the rotating shaft is connected to a conveyor belt through a conveyor roller, and a placing table is arranged on the outer wall of the conveyor belt. By placing the pipe fittings on the placing table in sequence, the driving motor is turned on to drive the rotating shaft to rotate synchronously, and the rotating shaft drives the conveyor belt, the placing table and the pipe fittings to move toward one side of the punching assembly.

[0015] As a further preferred embodiment of the present technical solution, the punching assembly includes a first cylinder fixedly mounted on the top of the frame, the output end of the first cylinder is fixedly connected to a fixed disk, servo motors are arranged on both sides of the fixed disk, and a punching piece is arranged at the output end of the servo motor.

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

[0017] The disc enters the inner diameter of the pipe and supports the inner wall of the pipe on one side of the drilling position, evenly dispersing the pressure and effectively reducing the deformation or collapse of the pipe caused by external forces. Especially for thin-walled pipes, this design can prevent the inner wall from collapsing inward due to uneven pressure during drilling, ensure that the hole diameter meets the design requirements, maintain the rigidity of the pipe during the drilling process, prevent the hole position from shifting due to vibration or impact, and significantly reduce the risk of pipe scrapping.

[0018] Through the support of the first support frame and the clamping and fixing of the second support frame, effective constraints on the pipe fittings in both vertical and horizontal directions are achieved, which greatly improves the stability of the pipe fittings under various working conditions, reduces processing errors, damage and other problems caused by shaking or displacement of the pipe fittings, and improves production efficiency and product quality.

[0019] By starting the second cylinder, the disc can be controlled to move outward and removed from the pipe, which is convenient for handling the pipe after the drilling operation is completed. At the same time, before drilling, the position of the disc can be adjusted according to the inner diameter of the pipe to ensure that the disc can accurately enter the inner diameter of the pipe and be located on one side of the drilling location.

Specific embodiments

[0029] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the specification. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Embodiment 1: In combination with Figures 1-8 As shown, the present invention provides a technical solution: A PE three-way pipe fitting end processing device includes a frame 1. Inside the frame 1, there is a conveying component 2 for conveying the pipe fitting to one side. On both sides of the conveying component 2, there is a control component 4 for positioning the position of the pipe fitting. On the top of the frame 1, there is a punching component 3 for punching the pipe fitting;

[0031] The control component 4 includes a fixing frame 41 fixedly installed on the frame 1. On both sides of the fixing frame 41, a first support frame 42 and a second support frame 43 are respectively arranged. The first support frame 42 and the second support frame 43 are used for positioning the pipe fittings. A sliding plate 44 is slidably connected to the fixing frame 41. On one side of the sliding plate 44, a circular ring 45 is fixedly connected. At the center of the circular ring 45, a fixing rod 48 fixedly installed on the sliding plate 44 is arranged. Four connecting rods 46 are fixedly connected between the fixing rod 48 and the connecting rod 46. A sliding sleeve 410 is slidably connected to the outer wall of the connecting rod 46. On one side of the sliding sleeve 410, a moving rod 411 is fixedly connected;

[0032] On one side of the fixing rod 48, a disc 49 adapted to the inner diameter of the pipe fitting is fixedly connected. A chute 47 is opened on the outer wall of the disc 49, and one end of the moving rod 411 is slidably installed in the chute 47;

[0033] A second cylinder 414 is fixedly installed on the sliding plate 44. The output end of the second cylinder 414 is fixedly connected with a slider 415 slidably installed on the fixing rod 48. Four push rods 412 are rotatably connected around the outer wall of the slider 415. The other end of the push rod 412 is rotatably connected with the sliding sleeve 410;

[0034] A rectangular groove 416 is opened on the surface of the sliding plate 44. Above the sliding plate 44, a third cylinder 429 fixedly installed on the frame 1 is arranged. The output end of the third cylinder 429 is fixedly connected with a lifting plate 428. A curved rod 430 is fixedly connected to the side wall of the lifting plate 428. A swing plate 431 rotatably installed on the lifting plate 428 is slidably connected to the curved rod 430, and the swing plate 431 corresponds to the position of the rectangular groove 416. On both sides of the swing plate 431, a fourth damping spring 432 and a blocking rod 433 are respectively arranged. The fourth damping spring 432 is sleeved on the curved rod 430. The blocking rod 433 is fixedly installed on the lifting plate 428. A push plate 434 is fixedly connected to the side wall of the swing plate 431;

[0035] On the structure of the fixing frame 41, a mounting block 420 is carefully designed and installed. This mounting block 420 has a special function. It can be slidably connected with a trapezoidal block 424. One end of the trapezoidal block 424 is firmly fixedly connected to the second support frame 43 to ensure the structural stability. The other end of the trapezoidal block 424 is connected to a limiting block 422. A second damping spring 423 is ingeniously arranged between the limiting block 422 and the mounting block 420. The function of this spring is to provide a certain resistance to ensure that the trapezoidal block 424 can be properly controlled and buffered during sliding;

[0036] The design of the sliding plate 44 is also exquisite. The outer part of it is fixedly connected with a connecting plate 417. On both sides of the connecting plate 417, there are fixedly connected with first damping springs 418. The other ends of these springs are fixedly installed on the fixing blocks 419 on the fixing frame 41. The existence of the first damping springs 418 provides additional stability and buffering for the sliding plate 44 during movement, ensuring the smooth operation of the entire system;

[0037] In addition, the inner part of the sliding plate 44 is also fixedly connected with a trapezoidal block 424. On both sides of the trapezoidal block 424, there are vertical rods 425 fixedly installed on the fixing frame 41. A mounting plate 426 fixedly connected with the first support frame 42 is slidably connected to the vertical rods 425. On the top of the mounting plate 426, there is a third damping spring 427 sleeved on the vertical rod 425. The function of the third damping spring 427 is similar to that of the second damping spring. It provides necessary resistance and buffering for the sliding of the trapezoidal block 424 in the vertical direction, further enhancing the stability and reliability of the entire structure.

[0038] In the embodiment of the present invention, during the process that the conveying component 2 moves the pipe fitting to the position of the punching component 3, by starting the third air cylinder 429, the lifting plate 428 and the swing plate 431 are driven to move downward. The bottom end of the swing plate 431 will insert into the rectangular groove 416, causing the swing plate 431 to rotate and compress the fourth damping spring 432. As the swing plate 431 descends, it can push the sliding plate 44 to move inward. The movement of the sliding plate 44 will drive the ring 45, the fixed rod 48 and the disc 49 to move inward together. In this way, the disc 49 can enter the inner diameter of the pipe fitting and be located on one side of the punching position. The function of the disc 49 is to support the inner wall of the pipe fitting at the punching position to disperse the pressure and reduce the deformation or collapse of the pipe fitting caused by the externally applied force. Especially for thin-walled pipe fittings, this is particularly important. Through the support of the disc 49, the pressure can be evenly dispersed, avoiding the inward collapse of the inner wall due to uneven pressure during punching, thus avoiding problems such as uneven hole diameter or scrapping of the pipe fitting. The internal support function of the disc 49 ensures that the hole diameter meets the design requirements, and at the same time maintains the rigidity of the pipe fitting during punching, preventing the hole position from shifting due to vibration or impact;

[0039] When the sliding plate 44 moves inward, it will also drive the connecting plate 417 to move synchronously and compress the first damping spring 418. At the same time, the movement of the sliding plate 44 will also drive the trapezoidal block 424 to move inward. The movement of the trapezoidal block 424 will push the first support frame 42 and the mounting plate 426 to move upward and compress the third damping spring 427. In this way, the first support frame 42 can effectively support the pipe fitting. At the same time, the swing plate 431 can drive the pushing plate 434 to rotate synchronously during the rotation process. The rotation of the pushing plate 434 will push the limiting block 422, the sliding rod 421 and the second support frame 43 to move inward and compress the second damping spring 423. This enables the first support frame 42 and the second support frame 43 to support and clamp the pipe fitting. The trapezoidal block 424 is driven to move inward by the sliding plate 44, pushing the first The support frame 42 and the mounting plate 426 move upward and compress the third damping spring 427, thereby achieving vertical support for the pipe fitting, which prevents the pipe fitting from being displaced or shaken in the vertical direction, and ensures the stability of the pipe fitting during processing, transportation, etc. The rotation of the swing plate 431 drives the push plate 434 to rotate synchronously, pushing the limit block 422, the slide bar 421 and the second support frame 43 to move inward and compress the second damping spring 423, thereby achieving horizontal clamping of the pipe fitting, which further prevents the pipe fitting from moving in the horizontal direction and enhances the stability of the pipe fitting. Through the support of the first support frame 42 and the clamping and fixing of the second support frame 43, effective constraints on the pipe fitting in both vertical and horizontal directions are achieved, which greatly improves the stability of the pipe fitting under various working conditions and reduces processing errors, damage and other problems caused by shaking or displacement of the pipe fitting.

[0040] By starting the second cylinder 414, the slider 415 will slide to one side on the fixed rod 48, and the fixed rod 48 cooperates with the push rod 412 to push the sliding sleeve 410 on the connecting rod 46 to slide outward, so that the sliding sleeve 410 drives the moving rod 411 to move outward. After the moving rod 411 fits the inner wall of the pipe, the second cylinder 414 is closed;

[0041] After the punching operation is completed, by starting the third cylinder 429, the lifting plate 428 and the swing plate 431 will move upward, and the sliding plate 44 will move and reset under the elastic force of the first damping spring 418. At the same time, by starting the second cylinder 414, the disc 49 is controlled to move outward, so that the disc 49 moves out of the pipe, and the first support frame 42 moves and resets under the elastic force of the third damping spring 427.

[0042] Embodiment 2: Combination Figure 2As shown, on the basis of embodiment 1, the conveying component 2 includes a driving motor 21 fixedly mounted on one side of the frame 1, a rotating shaft 22 is rotatably arranged on both sides of the frame 1, and the output end of the driving motor 21 is fixedly connected to the rotating shaft 22, the outer wall of the rotating shaft 22 is connected to the conveyor belt 23 through a conveyor roller transmission, and the outer wall of the conveyor belt 23 is provided with a placing table 24, by placing the pipe fittings on the placing table 24 in sequence, by turning on the driving motor 21 to drive the rotating shaft 22 to rotate synchronously, the rotating shaft 22 drives the conveyor belt 23, the placing table 24 and the pipe fittings to move toward the side of the punching component 3.

[0043] In the embodiment of the present invention, the driving motor 21 is turned on to drive the rotating shaft 22 to rotate synchronously, and the rotating shaft 22 drives the conveyor belt 23, the placement table 24 and the pipe to move toward the side of the punching assembly 3.

[0044] Example 3: Combination Figure 3 As shown, on the basis of the second embodiment, the punching assembly 3 includes a first cylinder 31 fixedly mounted on the top of the frame 1, the output end of the first cylinder 31 is fixedly connected to a fixed disk 32, servo motors 33 are arranged on both sides of the fixed disk 32, and a punching piece 34 is arranged at the output end of the servo motor 33. The first cylinder 31 is turned on to drive the fixed disk 32, the servo motor 33, and the punching piece 34 to move downward, so that the positions of the punching piece 34 and the pipe fitting correspond to each other, and then the servo motor 33 is turned on to drive the punching piece 34 to rotate, so that the punching piece 34 punches holes on the pipe fitting.

[0045] In an embodiment of the present invention, the first cylinder 31 is turned on to drive the fixed plate 32, the servo motor 33, and the punching member 34 to move downward, so that the positions of the punching member 34 and the pipe fitting correspond to each other, and then the servo motor 33 is turned on to drive the punching member 34 to rotate, so that the punching member 34 punches holes in the pipe fitting.

[0046] Working principle of PE three-way pipe end processing equipment: by turning on the driving motor 21 to drive the rotating shaft 22 to rotate synchronously, the rotating shaft 22 drives the conveyor belt 23, the placement table 24 and the pipe to move to the side of the punching component 3;

[0047] When the conveying assembly 2 moves the pipe fitting to the position of the punching assembly 3, the third cylinder 429 is activated to drive the lifting plate 428 and the swing plate 431 to move downward, so that the bottom end of the swing plate 431 is inserted into the rectangular groove 416, causing the swing plate 431 to rotate and compress the fourth damping spring 432. As the swing plate 431 descends, it can push the sliding plate 44 to move inward, causing the sliding plate 44 to drive the circular ring 45, the fixing rod 48, and the disc 49 to move inward, and the disc 49 to enter the inner diameter of the pipe fitting, so that the disc 49 is located on one side of the punching position, enabling the disc 49 to support the inner wall of the pipe fitting at the punching position. During punching, the force applied externally may cause the pipe fitting to deform or collapse, especially for thin-walled pipe fittings. The disc 49 supporting the inner wall can evenly disperse the pressure, reducing the deformation of the pipe fitting caused by uneven stress, and preventing the inner wall from collapsing inward due to pressure during punching, which may result in uneven hole diameters or scrapping of the pipe fitting. The support of the disc 49 can prevent such problems and ensure that the hole diameter meets the design requirements. The disc 49 provides internal support to keep the pipe fitting rigid during the punching process, avoiding the deviation of the hole position caused by vibration or impact;

[0048] When the sliding plate 44 moves inward, it drives the connecting plate 417 to move synchronously and compresses the first damping spring 418;

[0049] Meanwhile, the sliding plate 44 drives the trapezoidal block 424 to move inwards, causing the trapezoidal block 424 to push the first support frame 42 and the mounting plate 426 upwards and compress the third damping spring 427, enabling the first support frame 42 to support the pipe fitting. At the same time, when the swing plate 431 rotates, it can drive the push plate 434 to rotate synchronously, so that the push plate 434 can push. There is a third damping spring 427 sleeved on the vertical rod 425. The function of the third damping spring 427 is the same as that of the second damping spring 423. Furthermore, the first support frame 42 supports the pipe fitting, and the second support frame 43 clamps and fixes the pipe fitting. By driving the trapezoidal block 424 to move inwards through the sliding plate 44, the first support frame 42 and the mounting plate 426 are pushed upwards and the third damping spring 427 is compressed, enabling the first support frame 42 to support the pipe fitting. This provides a vertical support force for the pipe fitting, preventing the pipe fitting from displacing or shaking in the vertical direction and ensuring the stability of the pipe fitting during processing, transportation, etc. The swing plate 431 rotates to drive the push plate 434 to rotate synchronously. There is a third damping spring 427 sleeved on the vertical rod 425. The function of the third damping spring 427 is the same as that of the second damping spring 423, enabling the second support frame 43 to clamp and fix the pipe fitting. This provides a horizontal clamping force for the pipe fitting, further preventing the pipe fitting from moving in the horizontal direction and enhancing the stability of the pipe fitting. Through the support of the first support frame 42 and the clamping and fixing of the second support frame 43, effective constraints on the pipe fitting in both the vertical and horizontal directions are achieved, greatly improving the stability of the pipe fitting under various working conditions and reducing problems such as processing errors and damage caused by the shaking or displacement of the pipe fitting;

[0050] By activating the second cylinder 414, the slider 415 is driven to slide on the fixed rod 48 towards one side, causing the fixed rod 48 to cooperate with the push rod 412 to push the sliding sleeve 410 to slide outwards on the connecting rod 46. Consequently, the sliding sleeve 410 drives the moving rod 411 to move outwards. After the moving rod 411 fits against the inner wall of the pipe fitting, the second cylinder 414 is turned off;

[0051] By activating the first cylinder 31, the fixed disk 32, the servo motor 33, and the punching member 34 are driven to move downwards, so that the position of the punching member 34 corresponds to that of the pipe fitting. Then, the servo motor 33 is activated to drive the punching member 34 to rotate, enabling the punching member 34 to perform punching on the pipe fitting;

[0052] After punching, by activating the third cylinder 429, the lifting plate 428 and the swing plate 431 are driven to move upwards. The sliding plate 44 moves back to its original position under the elastic force of the first damping spring 418. By activating the second cylinder 414, the control disk 49 is moved outwards, causing the control disk 49 to move out of the pipe fitting. The first support frame 42 moves back to its original position under the elastic force of the third damping spring 427.
