Description

Technical Field

[0001] The invention relates to the technical field of pipe making equipment, and in particular to a mixed pipe making machine for round and square pipes. Background Art

[0002] The forming process of existing pipe-making equipment involves a feeder feeding the pipe material via a conveyor belt into a forming device. The forming device then forms the initial cylindrical pipe material, which is then welded and rounded to obtain the final finished pipe material. The finished pipe material is then cut to the required length. The forming device of this pipe-making equipment uses rollers to extrude the pipe material into shape. This roller extrusion method is prone to uneven force during the extrusion process, which can cause the pipe material's shape to change. This can lead to uneven joints in the pipe material, affecting the forming quality and subsequent welding process, resulting in reduced product quality. Furthermore, existing pipe-making equipment has difficulty in simultaneously producing round and square pipes, resulting in low pipe-making efficiency.

[0003] To address the shortcomings of existing technologies, researchers have conducted extensive research and proposed various solutions. For example, a Chinese patent document discloses a pipe-making device [CN201520611087.6] that uses an auxiliary forming and conveying device on the pipe-making device to roll the unrolled pipe into a cylindrical shape and convey it to a high-frequency welding device. The auxiliary forming and conveying device is equipped with a conveyor belt, a forming wheel, a mandrel, and a reel. The conveyor belt carries the unrolled pipe through the reel, forming wheel, and mandrel in sequence, gradually rolling the unrolled pipe into a cylindrical shape. The formed pipe is then heat-melted to the inner and outer surfaces of the pipe by an internal high-frequency welding device and an external high-frequency welding device.

[0004] The above solution has solved to a certain extent the problem that the roller extrusion molding method in the existing pipe making equipment easily causes uneven force and affects the molding quality. However, this solution still has many shortcomings, such as: it is difficult to achieve synchronous pipe making of round pipes and square pipes, which affects the pipe making efficiency.
