Embodiment Construction
[0019] The present invention is described in further detail now in conjunction with accompanying drawing. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.
[0020] Such as Figure 1-4 As shown, it is the best embodiment of the present invention, a kind of anti-deformation pipe bending tool, comprising a mandrel 2 and an elastic collet 1 sleeved on the outside of the mandrel 2, the outer shape of the collet 1 is roughly cylindrical, and the elastic collet The outer diameter of the upper half of the head 1 is slightly larger than the outer diameter of the lower half of the collet 1, so that a step 16 is formed between the upper half of the collet 1 and the lower half of the collet 1, and the collet 1 The inside has a through hole matching the shape of the mandrel 2,
[0021] The through hole of the collet 1 is div...

The invention relates to the technical field of pipe bending, in particular to an anti-deformation pipe bending tool. The anti-deformation pipe bending tool comprises a mandrel and an elastic chuck, wherein the mandrel is sleeved with the elastic chuck. A through hole of the elastic chuck is divided into an upper through hole section, a middle through hole section and a lower through hole section. The upper through hole section is in a smooth reversed-cone shape. The middle through hole section is in a smooth cylinder shape. The lower through hole section is in a cylinder shape with an internal thread. Longitudinal vertical grooves are formed in the upper end face of the upper half section of the elastic chuck. A round hole is transversely formed in the lower half section of the elastic chuck. The vertical grooves extend to the round hole and the bottoms of the vertical grooves are communicated with the round hole. The mandrel is divided into an upper mandrel section, a middle mandrel section and a lower mandrel section. The upper mandrel section is in a smooth reversed-cone shape. The lower mandrel section is provided with an external thread matched with the lower through hole section. The anti-deformation pipe bending tool has the beneficial effects that the section of a straight line section connected with a bent portion is prevented from being deformed in the pipe bending process, product quality is improved, product use performance is enhanced, and safety is guaranteed.
Description
technical field [0001] The invention relates to the technical field of pipe fitting bending processing, in particular to a deformation-resistant pipe bending tool. Background technique [0002] At present, pipe bending technology is widely used in many industries such as high-speed rail, automobile, aerospace, shipbuilding, etc. The quality of the product directly affects the installation and safety of its use. During the bending process, the curved part of the pipe will gradually become flattened, and the inner wall of the part where the pipe needs to be bent bears a large deformation force, which will easily lead to distortion of the section of the straight line near the part where the pipe needs to be bent. At present, there are no effective measures to solve this kind of problem. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the technical problem in the prior art that the section of the straight se...
