Description

Technical Field

[0001] This utility model relates to the field of rectangular corrugated tube roll forming technology, and in particular to a rectangular corrugated tube roll progressive forming device. Background Technology

[0002] The rectangular corrugated pipe roll forming device is a specialized industrial equipment that uses multiple sets of rollers to gradually roll and bend metal sheets, such as steel plates and aluminum plates, to continuously form a rectangular cross-section corrugated structure. Its core feature is roll forming, which uses roller pressure to shape and gradually complete the forming step by step and in stages, rather than a one-time stamping. It is mainly used for the mass production of rectangular corrugated pipes. These corrugated pipes are widely used in pipelines, heat exchangers, pressure vessels, building ventilation and other scenarios, and have the advantages of rigidity, corrosion resistance and heat exchange or flow guiding efficiency.

[0003] Currently, when transporting two gas streams simultaneously, two circular corrugated pipes are used. This integrated structure occupies a large space, wastes materials, is not resistant to high temperatures, is easily damaged, and has a short service life. The existing patent (publication number: CN210165024U) includes a rectangular corrugated pipe body. A first mounting flange and a second mounting flange are welded to the two end faces of the rectangular corrugated pipe body, respectively. The first and second mounting flanges each have two first inlets / outlets and two second inlets / outlets, respectively. The diameter of the first inlets / outlets is smaller than that of the second inlets / outlets. Each first inlet / outlet is welded with a first guide pipe, and each second inlet / outlet is welded with a second guide pipe. Each first guide pipe extends into the corresponding second guide pipe and extends into the corresponding second inlet / outlet. The first and second mounting flanges also have first bolt mounting holes and second bolt mounting holes, respectively. This invention has good seismic resistance. The rectangular corrugated pipe body has a built-in two-layer inner and outer guide pipe structure, allowing two gas paths to pass simultaneously. The inner and outer guide pipes effectively attenuate the inlet temperature, reduce the surface temperature of the rectangular corrugated pipe, and extend its service life.

[0004] To address the aforementioned issues, existing patents have provided solutions. However, existing rectangular corrugated tube forming devices typically use a stamping machine to stamp the rectangular corrugated tube multiple times to process it. While this method can process rectangular corrugated tubes, it has low processing efficiency, a relatively simple structure, and cannot achieve other auxiliary effects during the processing of rectangular corrugated tubes, thus lacking practicality.

[0005] To address this, a roll forming device for rectangular corrugated tubes is proposed. Utility Model Content

[0006] The purpose of this invention is to provide a roll forming device for rectangular corrugated tubes, which can solve the problems of existing rectangular corrugated tube forming devices, which usually use a stamping machine to stamp the rectangular corrugated tube multiple times to process it. Although this method can process rectangular corrugated tubes, the processing efficiency is low, the structure is relatively simple, and no other auxiliary effects can be achieved during the processing of rectangular corrugated tubes, resulting in insufficient practicality.

[0014] Preferably, a limit frame is fixedly connected to the top of the fixed frame, the hydraulic cylinder is fixedly connected to the inner wall of the limit frame, and a PLC controller is fixedly connected to the left side of the fixed frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1.

The processing efficiency is increased to several times that of the traditional method, thereby improving the processing quality and production capacity of rectangular corrugated pipes.

By setting the auxiliary mechanism 2, it can provide support in terms of plate straightening, traction conveying, and precise cutting. The two work together to realize the integrated processing flow of plate pretreatment, roll forming, secondary straightening and precise cutting.

[0021] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the auxiliary mechanism 2 includes an electric telescopic rod 21 and a straightening roller 22. The electric telescopic rod 21 is fixedly connected to the top of both sides of the base plate 3, and the straightening roller 22 is fixedly connected to the output end of the electric telescopic rod 21. The electric telescopic rod 21 is fixedly connected to the rear of the fixed frame 15.

[0022] Specifically, such as Figure 4 As shown, a number of shaped gears 18 have fixed shafts 5 fixedly connected to their inner walls, and the fixed shafts 5 are movably connected to the inner wall of the mounting frame 17.

[0023] Specifically, such as Figure 4As shown, the servo motor 19 is fixedly connected to the left side of the fixed shaft 5, and the surface of the fixed shaft 5 is fitted with a synchronous belt 4.

[0024] In this embodiment: by setting an electric telescopic rod 21, the straightening roller 22 can be driven to rise and fall. By setting the straightening roller 22, the rectangular corrugated tube can be straightened twice. By setting a synchronous belt 4, the shaping gear 18 can be driven to rotate synchronously to achieve progressive roll forming.

[0025] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, a traction device 28 is fixedly connected to the top of the base plate 3, and the traction device 28 is fixedly connected to the rear of the electric telescopic pole 21.

[0026] Specifically, such as Figure 2 , Figure 5 As shown, an assembly frame 23 is fixedly connected to the top of the base plate 3, a hydraulic rod 6 is fixedly connected to the top of the assembly frame 23, and an encoder 24 is fixedly connected to the surface of the output end of the hydraulic rod 6 and the surface of the output end of the traction device 28.

[0031] Working principle: When the user needs to process rectangular corrugated pipes, the processing parameters are first preset through the PLC controller 29, including the corrugated pipe specifications, forming pressure, cutting length, etc. After that, the metal sheet is installed on the unwinding device 11. Then, the power is turned on and the equipment is started. The unwinding device 11 automatically unwinds the sheet, and the sheet is conveyed to the area below the straightening plate 14. The electric push rod 13 drives the straightening plate 14 to move down to pre-process the sheet and remove wrinkles. The pre-processed sheet is then conveyed to the forming gear 18, and the servo motor 19 drives the forming gear 18 through the synchronous belt 4. Multiple sets of shaping gears 18 operate synchronously, and hydraulic cylinders 16 adjust the height of mounting frame 17 to achieve progressive roll forming. After completion, the formed corrugated tube is transported to straightening roller 22 by traction device 28. Electric telescopic rod 21 adjusts the roller spacing for secondary straightening to ensure corrugation consistency. When the corrugated tube reaches the preset length, encoder 24 sends a signal, and hydraulic rod 6 drives cutting blade 26 to move down to complete precise cutting. Finally, the cut finished product falls and is collected, and traction device 28 continues to transport the sheet material for the next batch of processing.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
