Description

Technical Field

[0001] The utility model relates to the technical field of PE pipe cutting, in particular to a PE pipe section cutting fixing tool. Background Art

[0002] PE pipe is a commonly used polymer flexible pipe and is used in many fields, including the transportation of water, gas and other media, and the protection of cables. PE pipe processing and production are generally in accordance with the standard length of 6m. When PE pipe is actually installed and used, it must be cut on site according to user needs to obtain the appropriate length. In order to ensure the cutting accuracy and the flatness of the cross-section, the PE pipe must be fixed to prevent it from shaking and deviating during the cutting process.

[0003] At present, PE pipe cutting and fixing is generally done by operators manually pressing and steadying the PE pipe. Although it can prevent the PE pipe from shifting to a certain extent, it is laborious to press and steady the pipe for a long time, especially for the continuous cutting and processing of multiple pipes, the time of manual support of the pipe is longer. When cutting, the operator holds the pipe with one hand and operates the cutting machine with the other hand. It is not reliable to hold the pipe with one hand, and some PE pipes have thin walls, which may cause the pipe to sag and deform when pressed and fixed manually.

[0004] Therefore, in view of the fact that the existing method of manually pressing to stabilize the PE pipe during cutting is rather laborious and easily causes deformation of the pipe fittings, a hoop PE pipe fitting can be designed to achieve a fixing tool to replace manual support for stabilization, with good fixing effect and convenient continuous cutting operations.

The support ring A No. 2 end piece 9 on one side of the movable support frame 4 is fixedly connected to 8, and an assembly connector is provided between the No. 1 end piece 7 and the fixed support frame 6. According to the diameter of the PE pipe to be cut, the movable support frame 4 and the support ring 8 with a suitable bayonet 5 are selected, and then the movable platform 3 is inserted from between the slide rails 2, and then the No. 1 end piece 7 is installed on the fixed support frame 6 through the assembly connector. By sliding the movable platform 3 toward the fixed support frame 6, the bayonet 5 and the support ring 8 are brought close to each other to form an annular cavity. Flexible cushioning layers are provided on the inner walls of the bayonet 5 and the support ring 8. When the PE pipe penetrates into the annular cavity, it is locked by the fixed support frame 6, the movable support frame 4 and the support ring 8 to prevent the PE pipe from moving during the cutting process.

[0030] Example 1: Please refer to Figure 1-Figure 4In this embodiment, the assembly connector includes a beam frame 1001, a socket 1002, a plug plate 1003 and a limit plate 1004; the fixed support frame 6 is a hollow structure and is fixedly connected to the beam frame 1001 inside. The upper end of the beam frame 1001 is provided with a socket 1002, and a plug plate 1003 adapted to the socket 1002 is fixedly connected to the side wall of the No. 1 end piece 7. The limit plate 1004 is fixedly connected to the plug plate 1003. The plug plate 1003 is plugged into the socket 1002 and the limit plate 1004 is pressed against the side wall of the beam frame 1001. The plug plate 1003 and the limit plate 1004 are connected from the fixed support. One side of the support frame 6 is inserted into the interior and moved downward from the top of the beam 1001, so that the plug plate 1003 enters the socket 1002, and forms a horizontal locking with the beam 1001 with the help of the limit plate 1004, so that the No. 1 end piece 7, the support ring 8 and the No. 2 end piece 9 remain fixed. At this time, the movable platform 3 moves, and the bayonet 5 and the support ring 8 on the movable support frame 4 will form an annular cavity with overlapping centers for locking the PE pipe. In order to prevent the bayonet 5 from being detached from the PE pipe due to the movement of the movable platform 3 after the annular cavity is formed, the movable platform 3 can be fixed by passing bolts through the movable platform 3 and tightening them to the support plate 1.

[0031] Example 2: Please refer to Figure 5-Figure 9 In this embodiment, the assembly connection includes a clamping ring 1005 and a connecting frame 1006; the clamping ring 1005 is fixedly connected to one side of the fixed support frame 6, and a notch is set on the upper edge of the clamping ring 1005. The connecting frame 1006 is fixedly connected between the left and right opposite end pieces 7. The connecting frame 1006 is pressed into and fixed in the clamping ring 1005 through the notch. The connecting frame 1006 is squeezed downward into the clamping ring 1005, so that the end piece 7 and the fixed support frame 6 are assembled together, and can be rotated with the connecting frame 1006 as the axis. When replacing, it is only necessary to pull the connecting frame 1006 upward from the clamping ring 1005. A through hole 11 is provided on the No. 2 end piece 9, and a notch 13 is provided on the side wall of the movable support frame 4. A pin is inserted into the through hole 11 12, the end of the latch 12 is inserted into the corresponding notch 13 and fixes the No. 2 end piece 9 to the movable support frame 4. When the movable platform 3 moves toward the fixed support frame 6, the connecting frame 1006 is rotated synchronously, and the bayonet 5 and the supporting ring 8 on the movable support frame 4 form an annular cavity with overlapping centers for locking the PE tube. In order to prevent the bayonet 5 from being separated from the PE tube due to the movement of the movable platform 3 after the annular cavity is formed, the latch 12 is inserted into the through hole 11 and the corresponding notch 13, and the movable support frame 4 is locked with the help of the No. 2 end piece 9. At the same time, the movable support frame 4 supports the No. 2 end piece 9 through the latch 12 to prevent the supporting ring 8 from rotating downward. In actual use, the latch 12 can use a spring pin, and with the help of the contraction and pulling effect of the spring, the pin is automatically inserted into the notch 13 to form a lock.

[0032] Through the above steps, the annular cavity formed by the movable support frame 4 and the fixed support frame 6 is pressed in opposite directions to form a locking ring, thereby preventing the PE pipe from moving during the cutting process. This replaces manual pressing and locking, which is more labor-saving and convenient for operating the cutting machine. The PE pipe will not be dented or deformed due to excessive squeezing force, thereby solving the problem that the existing method of using manual pressing to stabilize the PE pipe during cutting is labor-intensive and easily causes deformation of the pipe fittings.
