Description

Technical Field

[0001] The utility model belongs to the field of PE pipes, and in particular relates to a PE pipe bending device. Background Art

[0002] Bending PE pipes allows them to adapt to different installation environments and space requirements. The bent pipes can be better connected to other components, ensuring the tightness and stability of the piping system. Current PE pipe bending devices typically bend the pipe by pushing it forward, supported by a fixed rod.

[0003] However, this device has several significant drawbacks. First, its operation is cumbersome and laborious. Whenever a tube needs to be bent upward or downward, the fixed tube must be removed and repositioned before the bending process can begin. This process is not only time-consuming and labor-intensive, but also increases the workload of the operator. Each adjustment takes a significant amount of time, making the entire bending process lengthy and reducing efficiency.

[0004] This type of device has limited flexibility and can only be bent in specific ways, making it difficult to meet the bending requirements of different shapes and angles. It is therefore inadequate for diverse production tasks.

[0005] In view of this, we proposed a PE pipe bending device to solve this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a PE pipe bending device to solve the problems raised in the above background technology.

[0007] The utility model is realized by the following technical solutions: a PE pipe bending device comprises a bending table, a bending vertical rod is installed on the front side above the bending table, and two bending cross rods are installed behind the bending vertical rod;

[0008] A bending mechanism is provided on the upper rear side of the bending table, and the bending mechanism includes a vertical frame, an adjusting push rod and a threaded rod. An inner slider is installed in the middle of the vertical frame, and a threaded hole is opened in the middle of the inner slider. A threaded rod is rotatably connected to the threaded hole through a thread. A servo motor is installed above the vertical frame, and the output shaft of the servo motor is connected to the threaded rod.

[0009] An adjusting push rod is installed in front of the inner sliding block, a bending block is installed at the front end of the adjusting push rod, and pipe grooves are respectively provided on the front side and upper and lower sides of the bending block.

[0010] As a preferred embodiment, a lower bending opening is opened on the upper right side of the bending platform.

[0011] As a preferred embodiment, a support leg is installed on each of the four sides below the bending platform.

[0012] As a preferred embodiment, an electric slide is installed on the left side above the bending table, and the electric slide is connected to a linkage plate through a slider.

[0013] As a preferred embodiment, a positioning frame is installed in front of the linkage plate, and a clamping push rod is installed above the positioning frame.

[0014] As a preferred embodiment, a clamping half circle is provided on the upper interior of the positioning frame, a fixed half circle is installed below the clamping half circle, and the lower end of the clamping push rod is connected to the clamping half circle.

[0015] As a preferred embodiment, the clamping push rod and the adjusting push rod are both electric push rods.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. By setting up a bending mechanism, a bending cross bar and a bending vertical bar, the bending block can be driven to move up and down or forward during the bending process, so that the PE pipe can be bent in different directions to meet the bending requirements of different shapes and angles.

[0018] 2. By setting the positioning frame, the fixing half circle, the clamping half circle and the clamping push rod, the PE pipe can be clamped and fixed, so that the PE pipe is not easy to loosen when bending, and can be bent accurately according to the predetermined angle, ensuring the consistency and accuracy of the bending effect.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 3 The utility model provides a technical solution: a PE pipe bending device, comprising a bending platform 1, a bending vertical rod 5 is installed on the front side above the bending platform 1, and two bending cross bars 6 are installed behind the bending vertical rod 5;

[0028] A bending mechanism 7 is provided on the upper rear side of the bending table 1. The bending mechanism 7 includes a vertical frame 71, an adjusting push rod 75, and a threaded rod 73. An inner slider 74 is installed in the middle of the vertical frame 71. A threaded hole is provided in the middle of the inner slider 74. The threaded hole is rotatably connected to the threaded rod 73. A servo motor 72 is installed above the vertical frame 71. The output shaft of the servo motor 72 is connected to the threaded rod 73.

[0029] An adjusting push rod 75 is installed in front of the inner slide 74 , and a bending block 76 is installed at the front end of the adjusting push rod 75 . Pipe grooves 77 are respectively provided on the front side and the upper and lower sides of the bending block 76 .

[0030] A lower bending opening 3 is provided on the right side above the bending platform 1 .

[0031] A support leg 2 is installed on each of the four sides below the bending platform 1.

[0032] An electric slide 4 is installed on the left side above the bending table 1, and the electric slide 4 is connected to a linkage plate 8 through a slider.

[0033] A positioning frame 9 is installed in front of the linkage plate 8 , and a clamping push rod 10 is installed above the positioning frame 9 .

[0034] A clamping half circle 12 is provided on the upper part of the positioning frame 9 , a fixing half circle 11 is installed below the clamping half circle 12 , and the lower end of the clamping push rod 10 is connected to the clamping half circle 12 .

[0035] The clamping push rod 10 and the adjusting push rod 75 are both electric push rods.

[0036] See also Figure 1 and Figure 2 As the first embodiment of the present utility model: when in use, the left end of the PE pipe is inserted into the positioning frame 9, so that the right end passes between the two bending cross bars 6 and is located in front of the bending block 76, and then the clamping half circle 12 is driven down by the clamping push rod 10, so that the left end of the pipe is clamped and fixed between the clamping half circle 12 and the fixed half circle 11, thereby preventing the pipe from loosening during the bending process and affecting the bending effect.

[0037] See also Figures 1 to 3 , as a second embodiment of the present invention: according to the further elaboration of the first embodiment, after the PE pipe is fixed, the part of the pipe that needs to be bent can be heated and softened by a hot air gun, and then the electric slide 4 is started, so that the electric slide 4 drives the linkage plate 8 to move to the right through the slider, and the linkage plate 8 drives the positioning frame 9 to move to the right, thereby driving the fixed pipe to move to the right, so that the heated part of the pipe moves to between the two bending cross bars 6. If the pipe needs to be bent forward, the bending block 76 is driven forward by adjusting the push rod 75, and the bending block 76 pushes the pipe forward through the front pipe groove 77. Under the support of the bending vertical rod 5, the pipe can be bent forward. When the pipe needs to be bent upward or downward, the threaded rod 73 is driven to rotate in the threaded hole by the forward and reverse rotation of the servo motor 72, thereby driving the inner slider 74 to move up and down in the vertical frame 71 to adjust the height. The inner slider 74 can adjust the position of the bending block 76 by adjusting the push rod 75;

[0038] When it is necessary to bend upward, the servo motor 72 is reversed, and then the bending block 76 is driven to descend to the bottom of the pipe. Then, the bending block 76 is pushed to move to the bottom of the pipe by adjusting the push rod 75. The next step is to make the servo motor 72 rotate forward, so as to drive the bending block 76 to move upward. The bending block 76 pushes the pipe upward through the upper pipe groove 77. With the support of the upper bending cross bar 6, the upward bending is achieved. For downward bending, the bending block 76 can be moved to the bottom of the pipe in combination with the above steps. When bending downward, the pipe enters the lower bend 3, and the lower bend 3 provides a downward bending space for the pipe. During the bending process, the electric slide 4 can be used to drive the pipe to move horizontally to adjust the bending position.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
