[0002] There are two common continuous pipe bending methods at present: one is to use mechanical equipment. For large-scale production or situations requiring high-efficiency pipe bending, mechanical equipment can be used to continuously bend round pipes.

For example, an electric pipe bender can conveniently bend round pipes to achieve smooth and flat bending arcs. This method is suitable for use on production lines or applications with high requirements for pipe bending quality. The other is to use mold forming. In industrial production, mold forming is a common method. By designing a specific mold, round pipe materials can be placed in the mold, and then the round pipe can be bent according to the shape of the mold through pressure or other methods. This method is suitable for mass production of the same shape of bent pipes and can ensure high precision and consistency. SUMMARY

DETAILED DESCRIPTION
[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0018] To facilitate understanding of the embodiments of this utility model, the following will provide further explanation and description with reference to the accompanying drawings and specific embodiments. These embodiments do not constitute a limitation on the scope of protection of this utility model.
[0019] In pipe bending operations, there may be a need for continuous pipe bending, meaning the distance between bending sections is too short. This is especially true in bending pipes in confined spaces, where not only are the bending distances too close, but the bending directions are also different. Therefore, this specific embodiment provides a continuous pipe bending device that improves the consistency of pipe forming while simplifying operation. Figure 1 As shown, the continuous pipe bending device includes a clamping device 1, a main clamp 2, and a secondary clamp 3.
[0020] The clamping device 1 clamps the upper end of the pipe fitting 6 to be formed, while the main clamp 2 and the auxiliary clamp 3 surround the lower end of the pipe fitting 6 from both sides, restricting the pipe fitting 6 from shaking. When an external force is applied to the clamping device 1, it drives the pipe fitting 6 to engage with the forming grooves on the main clamp 2 and the auxiliary clamp 3, thereby forming the pipe fitting 6 into the desired shape under the restraining action of the main clamp 2 and the auxiliary clamp 3.
[0021] The main clamp 2 includes a first main clamp 2-1, a second main clamp 2-2, and a third main clamp 2-3, as follows: Figures 2-3 As shown, the main clamp surrounds the tube fitting 6 to be formed from the left side. The secondary clamp 3 includes a first secondary clamp 3-1, a second secondary clamp 3-2, and a third secondary clamp 3-3, as shown. Figure 4 As shown, the secondary clamp surrounds the tube to be formed 6 from the right side.
[0022] The first main clamp 2-1 and the first auxiliary clamp 3-1 cooperate to form a first forming groove 4. The first forming groove 4 includes a first curved surface 4-1 and a second curved surface 4-2. The first curved surface 4-1 is disposed on the first main clamp 2-1, and the second curved surface 4-2 is disposed on the first auxiliary clamp 3-1. Furthermore, the ends of the first curved surface 4-1 and the second curved surface 4-2 near the clamping device 1 are far apart from each other, while the other ends are close together. The inner wall shapes of the first curved surface 4-1 and the second curved surface 4-2 are adapted to the shape of the pipe fitting 6 to be formed.
[0023] The end faces of the second main clamp 2-2 and the second auxiliary clamp 3-2 are attached to form a second forming groove 5, which includes a third curved surface 5-1 and a fourth curved surface 5-2, the third curved surface 5-1 is formed at the attachment of the second main clamp 2-2, and the fourth curved surface 5-2 is formed at the attachment of the second auxiliary clamp 3-2. The inner wall shape of the second forming groove 5 is adapted to the outer shape of the pipe to be formed 6.
[0024] Further, the first main clamp 2-1 and the second main clamp 2-2 are detachably connected together, and the first auxiliary clamp 3-1 and the second auxiliary clamp 3-2 are detachably connected together. In addition, the second main clamp 2-2 and the second auxiliary clamp 3-2 have multiple specifications, and the second main clamp 2-2 and the second auxiliary clamp 3-2 can be replaced with the required shape according to the forming requirements, so that the required main clamp or auxiliary clamp can be conveniently replaced.
[0025] Further, in order to firmly fix the pipe and high-quality forming, the first curved surface 4-1 and the third curved surface 5-1 are smoothly connected, and the second curved surface 4-2 and the fourth curved surface 5-2 are smoothly connected, so as to avoid the damage caused by the non-smooth inner wall at the connection to the pipe to be formed 6.
[0026] When the pipe to be formed 6 is bent by the continuous bending device, first, the upper end of the pipe to be formed 6 is clamped by the clamping device 1, and the lower end of the pipe to be formed 6 is fixed on the continuous bending device by the main clamp 2 and the auxiliary clamp 3. At this time, the lower end of the pipe to be formed 6 is accommodated in the second forming groove 5, and the lower end of the pipe to be formed 6 is positioned by the second forming groove 5, and the required bending part of the pipe to be formed 6 is attached to the second curved surface 4-2.
[0027] Then, an external force is applied to the clamping device 1 to drive the pipe to be formed 6 to rotate with the main clamp 2 and the auxiliary clamp 3, and in the process of rotation, the required bending part of the pipe to be formed 6 gradually moves away from the second curved surface 4-2 and is attached to the first curved surface 4-1, and the pipe to be formed 6 is bent into the required shape under the limitation of the first curved surface 4-1, at this time, the first bending work of the pipe to be formed 6 is completed.
[0028] After the first bending is completed, the second main clamp 2-2 and the second auxiliary clamp 3-2 are replaced with the required shape. In the specific embodiment, the second main clamp 2-2 is replaced with a third main clamp 2-3, and the second auxiliary clamp 3-2 is replaced with a third auxiliary clamp 3-3, as shown in Figure 5 The third main clamp 2-3 and the third auxiliary clamp 3-3 are attached to form a third forming groove 7, and the inner wall of the third forming groove 7 is formed into the required forming shape, as shown in Figure 6The third forming groove 7 is shown in the figure. At this time, the part of the pipe to be formed 6 required to be formed is pushed into the third forming groove 7 under the action of external force, and the pipe to be formed 6 is bent into the required shape under the limiting action of the third forming groove 7, at this time the second bending work of the pipe to be formed 6 is paired.
[0029] The above specific embodiments have further detailed the purpose, technical scheme and beneficial effects of the present application, and it should be understood that the above is only a specific embodiment of the present application and is not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
