Description

Device for cutting corrugated pipe flange wire

Technical Field

The utility model relates to a bellows field, especially a device for bellows flange wire-electrode cutting.

Background

The metal corrugated pipe is a pipe with a regular wave-like appearance, and the commonly used metal corrugated pipes comprise carbon steel, stainless steel, steel lining plastic, aluminum and the like. The connecting device is mainly used for connecting pipelines or connecting pipelines and equipment in occasions where small bending radius non-concentric axial transmission is needed, or irregular turning and stretching are needed, or thermal deformation of the pipelines and the like are absorbed, or the fixed elbow is inconvenient to install.

In the corrugated pipe production and manufacturing process, slotted holes need to be formed in flanges at two ends of partial products, the concentricity needs to reach 2-wire tolerance, welding deformation can occur when the flange holes are machined in the prior art and are welded, the size error is very large, and the product quality cannot be guaranteed.
