The power mechanism 1 has a fixed end and a moving end, and the movement of the power mechanism 1 The end is used to push the moving mechanism 2 close to the positioning mechanism 3, so that a channel for clamping and bending multiple pipelines is formed between the moving mechanism 2 and the positioning mechanism 3.
[0039] Wherein, the power mechanism 1 provides power for the movement of the moving mechanism 2, and when the pipe bending operation is performed, the positioning mechanism 3 does not operate, and the positioning mechanism 3 faces figure 1 The power mechanism 1 drives the moving mechanism 2 to move to the right, and the moving mechanism 2 is close to the positioning mechanism 3. Under the joint action of the moving mechanism 2 and the positioning mechanism 3, the clamping and bending of multiple pipelines is realized. The above pipeline batch bending tool does not require pure manual operation, which reduces the processing intensity, and can bend multiple instrument pipelines at the same time to realize batch processing of instrument pipelines.
[0040] The fixed end of the above-mentioned power mechanism 1 and the positioning mechanism 3 can be installed on a fixed table, and the moving end of the power mechanism 1 moves relative to the fixed end to push the moving mechanism 2 close to the positioning mechanism 3 .

After the placement is completed, the upper splint 41 can be rotated clockwise. The other components realize the connection with the upper splint 41.
[0046] Specifically, there is a folding connecting piece 6 at the connection between the upper splint 41 and the fixed end of the power mechanism 1 . The folding connector 6 may include a rotating shaft, the fixed end of the power mechanism 1 and the upper splint 41 are provided with a sleeve, the sleeve is sleeved on the rotating shaft and connected to the rotating shaft in rotation, or the folding connecting member 6 may also include a plurality of hinges, and many more.
[0047] In at least one embodiment, such as figure 2 As shown, the upper splint 41 is provided with an observation window 411. During the bending process, the operator can observe the bending arc of the pipeline through the observation window. When the bending arc reaches the required angle, control the power mechanism 1 to stop the action. . The setting of the observation window 411 is convenient for the operator to observe the pipeline, and effectively reduces the probability of occurrence of phenomenon such as bending transition or bending not up to standard.

[0050] The roller 5 is preferably a universal wheel, which can also have a locking function to assist rotation.
[0051] The positioning mechanism 3 is described in detail below:
[0052] In some embodiments, the positioning mechanism 3 includes two positioning mold assemblies 31 that are both connected to the splint assembly 4, and the two positioning mold assemblies 31 are respectively located on both sides of the moving direction of the moving mechanism 2, that is, as Figure 4 and Figure 5 As shown, there is a bending gap between the two positioning mold assemblies 31, and during the bending process, the moving mechanism 2 gradually approaches the bending gap.
[0053] In the above positioning mechanism, the two positioning mold assemblies 31 cooperate with the moving mechanism 2. When the power mechanism 1 pushes the moving mechanism 2 close to the bending gap, the two positioning mold assemblies 31 limit the position of the pipeline, and the moving mechanism 2 moves from the two A pressure is given to the pipeline between the two positioning mold assemblies 31. At this time, the force application points of the two positioning mold assemblies 31 on the pipeline are located on both sides of the force application point of the moving mechanism 2 on the pipeline, so as to realize stable bending of the pipeline.
[0054] Specifically, the two positioning mold assemblies 31 are arranged symmetrically with respect to the moving direction of the moving mechanism 2, so that the bent pipeline has a symmetrical bending arc.
[0055] On the basis of the above examples, if figure 2 and Figure 4 As shown, the cross-sections of the upper splint 41 and the lower splint 42 are trapezoidal, the corresponding end of the shorter top edge of the trapezoid is connected to the fixed end of the power mechanism 1, and the corresponding end of the longer bottom edge of the trapezoid is connected to the two positioning The mold assembly 31 is connected.
