[0015] The following will describe the technical solutions in the embodiments of the present invention in detail in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0017] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0018] Combination Figure 1-3As shown, the arc-shaped profile expansion tooling includes an upper cover plate 100 and a lower cover plate 200, which are fitted together. An arc-shaped groove 201 for accommodating the arc-shaped profile 300 is formed on the top surface of the lower cover plate 200, and the arc-shaped groove 201 is fitted to the arc-shaped profile 300. The interior of the arc-shaped profile 300 is hollow along its extension direction. The lower cover plate 200 is respectively equipped with a high-pressure spray gun 400 at the ports at both ends of the arc-shaped groove 201. The nozzle 401 of the high-pressure spray gun 400 is sealed and plugged into the port of the arc-shaped profile 300. The nozzle 401 of the high-pressure spray gun 400 protrudes to form a pressing sheet 402, and a pressing thorn is formed at the bottom of the pressing sheet 402 (not shown in the figure). The pressing sheet 402 extends into the interior of the arc-shaped profile 300 and the pressing thorn hooks the inner bottom surface of the arc-shaped profile 300.

[0019] In this technical solution, the concave part is eliminated by adding high-pressure water inside the profile, and during operation, the profile is hooked by pressing and piercing the profile to prevent the profile from retreating and causing dead wrinkles when adding high-pressure water.

[0020] During the specific operation, cover and fix the two cover plates, and insert the nozzle into the profile port. Since the pressing piece hooks the profile, the profile will not move back, and the concave can be eliminated after passing high-pressure water.

[0021] Furthermore, the high pressure spray gun 400 is installed in a box 403, the bottom of the box 403 is fixedly installed on a plate 404, and the plate 404 is movably installed on the bottom surface of the lower cover 200. The plate 404 drives the nozzle 401 of the high pressure spray gun 400 to move toward the end of the arc profile 300.

[0022] In this technical solution, the high-pressure spray gun needs to be moved, plugged into the port during operation, and pulled out when finished, so it needs to be moved and installed.

[0023] Furthermore, the nozzle 401 of the high-pressure spray gun 400 is formed with a conical surface for conveniently extending into the interior of the arc-shaped profile 300 .

[0024] In this technical solution, it is convenient to insert the port.

[0025] Furthermore, a plurality of reinforcing ribs 101 are formed on the top surface of the upper cover plate 100 .

[0026] In this technical solution, the structural strength is enhanced.

[0027] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0028] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
