Fully Automatic Variable Diameter Cage Welder

A factory that frequently changes drainage-pipe diameters needs cage production to change size without turning every product switch into a long setup. The Fully Automatic Variable Diameter Cage Welder is designed for continuous reinforcement-cage forming across optional ranges of Φ300-1200 mm, Φ600-2000 mm, Φ800-2400 mm, Φ1500-3000 mm, and Φ2000-4000 mm, with suitable cage lengths of 2-4 m. It can be matched to cages for flat, tongue-and-groove, steel-socket, and socket-and-spigot pipes. Digital continuous diameter variation and adjustable spiral pitch give the production team a practical way to move between specifications while keeping the cage geometry aligned with the final pipe design.

Mechanically, the Fully Automatic Variable Diameter Cage Welder uses a push-bar feeding structure, full-digital welding control, and variable-frequency synchronized speed regulation. These functions are most useful when they are coordinated with the next forming stage. Jiangsu Zhongjian Concrete Machine Equipment Co., Ltd. also manufactures roller-suspension, centrifugal, and core-vibration pipe equipment as well as matching molds, so cage diameter, length, joint type, and downstream tooling can be reviewed together during selection. The aim is to have the finished cage enter the following process smoothly, with less on-site correction of dimensions or production rhythm.

During manufacture of the Fully Automatic Variable Diameter Cage Welder, inspection covers the welded structure, machined parts, electrical assembly, synchronization, and the completed operating condition. Every unit receives 100% inspection before shipment, and independent inspection can be supported. Special cage dimensions, non-standard production cycles, or renovation of an older line may be engineered from product drawings. The company reports more than 1,000 complete equipment sets in operation in China; those field applications are reflected in an emphasis on clear adjustment, stable continuous operation, and enough specification flexibility for later capacity or diameter expansion.
