Accordingly, the drawings and description are illustrative in nature and not intended to limit the scope of the claims. Furthermore, in the present description, the drawings are not to scale and like reference numerals refer to like parts.
As shown in fig. 1, the special-shaped pipeline shaping device of the present invention includes a first special-shaped pipeline shaping portion 1, a second special-shaped pipeline shaping portion 2, a fastener 3, and a temperature control unit 6, wherein the first special-shaped pipeline shaping portion 1 and the second special-shaped pipeline shaping portion 2 are block-shaped structures. The first special-shaped pipeline shaping part 1 comprises a first joint curved surface, and a first embedded groove 7 which is consistent with the extending and bending direction of the special-shaped pipeline is arranged along the first joint curved surface. The second special-shaped pipeline shaping part 2 comprises a second joint curved surface, and a second embedded groove 8 which is consistent with the extending and bending direction of the special-shaped pipeline is arranged along the second joint curved surface. After the first special-shaped pipeline shaping part and the second special-shaped pipeline shaping part are buckled, the first joint curved surface is jointed with the second joint curved surface, so that the shape and the size of a cavity formed by combining the first embedded groove and the second embedded groove are consistent with those of the special-shaped pipeline.
As shown in fig. 2, which is an exploded schematic view of the shaped pipeline shaping device, it can be seen that the lower surface of the first shaped pipeline shaping portion 1 is a first curved joint surface, which is a curved surface, and a first pre-buried groove 11 is formed on the first curved joint surface in a manner consistent with the extending and bending direction of the shaped pipeline. For example, fig. 3 shows the shape of the shaped pipeline and the shapes of the first shaped pipeline shaping part 1 and the second shaped pipeline shaping part 2 corresponding to the shaped pipeline. As shown in fig. 3, the special-shaped pipeline 4 includes a plurality of bends, specifically, a first pipeline 41, a second pipeline 42, a third pipeline 43, a fourth pipeline 44, and a fifth pipeline 45, which are integrally connected in sequence, wherein the first pipeline 41 is horizontal, the second pipeline 42 is bent upward linearly, the third pipeline 43 is horizontal, the fourth pipeline 44 is bent downward linearly, and the fifth pipeline 45 is bent upward in a curved manner. Correspondingly, the first curved joint surface and the second curved joint surface are also provided with a horizontal section, an upward plane bending section, a horizontal section, a downward plane bending section and an upward curved surface bending section which are sequentially corresponding. And, on the first joint curved surface, be provided with first embedded groove 7 along the surface of first joint curved surface, this first embedded groove 7 also has horizontal segment, straight bending section, horizontal segment, straight bending section and the curved bending section of curve that makes progress in proper order from this. Similarly, a second pre-buried groove 8 is provided on the second curved joint surface along the surface of the first curved joint surface, and the second pre-buried groove 8 thus also has a horizontal section, an upward straight-line bending section, a horizontal section, a downward straight-line bending section, and an upward curved bending section in this order. When the first special-shaped pipeline shaping part 1 is buckled with the second special-shaped pipeline shaping part 2, the first joint curved surface is in contact fit with the second joint curved surface, and the cavity formed by combining the first embedded groove 7 and the second embedded groove 8 is the shape and size of the special-shaped pipeline. It should be noted that, in this embodiment, the shape of the special-shaped pipeline is not limited, and for example, the special-shaped pipeline may be a pipe with a circular cross section, or may be a pipe with a square cross section. After the first special-shaped pipeline shaping part 1 and the second special-shaped pipeline shaping part 2 are buckled, after a pipeline for manufacturing the special-shaped pipeline penetrates into a cavity formed by combining a first embedded groove and a second embedded groove, the first special-shaped pipeline shaping part 1 and the second special-shaped pipeline shaping part 2 are reliably connected through the fastener 3, the first special-shaped pipeline shaping part 1 and the second special-shaped pipeline shaping part 2 are detachably connected through the fastener 3, and the repeated use of the shaping device can be met. The fastening member 3 may be, for example, a bolt passing through the first and second shaped pipe fixing portions 1 and 2.
Fig. 4 is a schematic diagram of the first special-shaped pipeline shaping part 1 and the second special-shaped pipeline shaping part 2 after being connected and locked. The embodiment is not limited to the form of the fastening member 3, and may be, for example, a clamp hoop surrounding the periphery of the profiled pipeline shaping portion 1 and the second profiled pipeline shaping portion 2, and the structure of the clamp hoop is the same as that of the pipe hoop, which is not described in detail herein. Or may be a snap connection provided on the shaped pipe shaping portion 1 and the second shaped pipe shaping portion 2, which will not be described in detail herein. As shown in fig. 5 and 6, fig. 5 is a perspective view of the first shaped pipe fixing portion 1, and fig. 6 is a perspective view of the second shaped pipe fixing portion 2.

The temperature control unit 6 needs to have a temperature adjusting function for satisfying the temperature required for shaping the special-shaped pipeline 4, and a constant temperature control function, such as an oven, a constant temperature heating plate and the like. The special-shaped pipeline is made of thermoplastic materials, namely, the pipeline which has thermoplastic characteristics and bending conditions and is softer (or is softer after being preheated) is made of thermoplastic plastics such as PU (polyurethane), polyolefin, PFA (small amount of copolymer of perfluoropropyl perfluorovinyl ether and polytetrafluoroethylene), PC (polycarbonate), PMMA (polymethyl methacrylate material) and the like.

And, the abnormal shape pipeline bracing piece 5 can adopt the material that the melting point is greater than the required design temperature of abnormal shape pipeline. In particular, the material can resist the temperature of more than 300 ℃, such as PTFE material. The special-shaped pipeline supporting rod is not required by all special-shaped pipeline shaping devices, but has the function of preventing the pipeline from collapsing after shaping for shaping the special-shaped pipeline with small bending radius and more bending radii.
In an optional embodiment, a plurality of first pre-buried grooves can be formed in the first special-shaped pipeline shaping portion, a plurality of second pre-buried grooves can be formed in the second special-shaped pipeline shaping portion, each first pre-buried groove corresponds to each second pre-buried groove, after the first special-shaped pipeline shaping portion and the second special-shaped pipeline shaping portion are buckled, the first pre-buried grooves correspond to the second pre-buried grooves to form a plurality of cavities, and each cavity can correspond to a special-shaped pipeline of one specification, so that special-shaped pipelines of multiple specifications can be produced simultaneously. Because the special-shaped pipelines are put into the same oven, the shaping temperature of each special-shaped pipeline is the same. Or a plurality of special-shaped pipeline shaping devices can be placed into the oven, and the special-shaped pipelines with various specifications can be produced simultaneously.
