Helical gas pipe forming machines

Abstract

The invention relates to a novel spiral gas tube forming machine, which is applicable for spiral ducts formed by rolling strip steel roll material along a spiral involute track. The spiral gas tube forming machine comprises a frame (1); a material shelf (2), a lock forming set (3), a mold frame (4) and a cutting machine (5) arranged on the frame (1); and a discharge shelf (7) arranged on the front side of the cutting machine (5); wherein the frame (1) comprises a bottom plate (1.1), level adjusting bases (1.2), material shelf guide rails (1.3) and a platform (1.4); the material shelf (2) comprises a slider (2.1), a pillar (2.2), a main body (2.3) and a connection crank arm (2.5); the lock forming set (4) comprises a bottom plate (3.1), wall plates (3.2), a feed leveling device (3.3), an upper and a lower rib-pressing rollers (3.4), an upper and a lower roller groups (3.5), a discharge guide plate (3.6), an upper and a lower engagement wheels (3.7), and a pressing crank arm (3.8); and the mold frame comprises a support frame (4.1), guide rails (4.2), a template (4.3) and wind pipe baffles (4.5). The spiral gas tube forming machine has the advantages of simple structure, integration of the material shelf and the machine, good lock formability, multi-purpose of the mold frame, synchronous cutting without stopping, high production efficiency and good product quality.

Description

technical field [0001] The invention relates to a spiral gas pipe forming machine. It is widely applicable to take the strip steel coil as the base material and roll it into a spiral air tube shape along the spiral involute track. Background technique [0002] Spiral air duct is a new type of round air duct that has appeared recently. Because the area of ​​the circle with the same circumference is larger than that of square and rectangle, and there is no dead angle, it has the characteristics of smooth and beautiful inner wall, high strength, high sealing performance, and convenient construction and installation. Spiral ducts are widely used in central air-conditioning systems, indoor air purification, environmental protection and other industries. [0003] The spiral gas pipe forming machine is a special equipment for manufacturing spiral air pipes. Before the present invention was made, the novel spiral gas pipe forming machine in the past was a kind of traditional equip...

AI Technical Summary

Problems solved by technology

[0005] 2. The upper and lower roller groups cannot be adjusted; the upper and lower occlusal wheels have no power; the mold is difficult to process and the precision is poor, so the quality of the air duct produced is poor

[0006] 3. There is no cutting device, only manual cutting can be carried out, the cutting edge is not smooth, and the efficiency is low
