Metal rectangular rounded-corner/non-rounded-corner straight wave rolling device

Abstract

The invention discloses a metal rectangular rounded-corner / non-rounded-corner straight wave rolling device. The metal rectangular rounded-corner / non-rounded-corner straight wave rolling device comprises a pre-pressed sheet material, a guide device and a plurality of wave pressing devices. The sheet material passage positions of the guide device and the wave pressing devices are positioned on the same plane and are arranged and aligned; and the pre-pressed sheet material penetrates through the guide device and the plurality of wave pressing devices in sequence. According to the metal corrugated pipe sheet material prepared by the metal rectangular rounded-corner / non-rounded-corner straight wave rolling device, crests and troughs are symmetrical in structures and stable in shape. A metal corrugated pipe straight section product with any length can be obtained by the metal rectangular rounded-corner / non-rounded-corner straight wave rolling device without performing splitting and welding operations on a plurality of waveforms; and the work efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of metal bellows manufacturing, and more specifically relates to a metal bellows plate pressure wave processing device. Background technique [0002] Metal bellows is a kind of pipe that looks like a regular wave. Commonly used metal bellows include carbon steel and stainless steel, as well as steel-lined plastic and aluminum. Metal bellows are mainly used for non-concentric axial transmission that requires a small bending radius, or irregular turning, expansion and contraction, or thermal deformation of the absorption pipe. Metal bellows can also be used for pipe-to-pipe connections, or pipe-to-equipment connections where it is inconvenient to install with fixed elbows. The metal bellows has the characteristics of high strength, good flexibility, light weight, fast construction, long life, and low overall cost of ecological environmental protection projects. [0003] Metal bellows with a diameter of 1-2 m...
