Abstract

This invention discloses a double-spiral copper tube coiling machine and its process, belonging to the field of material processing and forming technology. It includes a spiral coiling mechanism and a control mechanism. The spiral coiling mechanism includes a frame, on which a clamping mechanism, a power head mechanism, an alignment mechanism, a spiral coiling fixture, a double copper tube introduction mechanism, and a locking fixture are sequentially connected. The clamping mechanism locks the center point via a tailstock sliding operating lever. The power head mechanism controls the rotation and rotation speed via a power head sliding operating lever. The alignment mechanism controls the alignment of the optical axis with the center point via an alignment mechanism pressure rod. The spiral coiling fixture is equipped with an optical axis, a center point, a spiral sleeve die, and a forming fixture. The end faces of the forming fixture and the spiral die are in spiral surface contact. The double copper tube introduction mechanism introduces the copper tube via a feeding trolley. This invention solves the shortcomings of existing technologies such as cross-sectional deformation, low precision, and poor efficiency, improving the processing precision, stability, and production efficiency of spiral coils and other workpieces.
