Figure-8 rib forming machine

The figure-8 rebar rolling machine is a specialized rebar processing equipment for underground engineering projects such as tunnels, subways, and high-speed railways. Its core function is the precise forming of figure-8 connecting bars for lattice arch frames. The equipment employs a hydraulic drive + double-cylinder synchronous transmission structure, coupled with custom-made molds made of high-wear-resistant alloy steel. The machine body is integrally welded from high-strength steel and undergoes aging treatment to effectively eliminate internal stress and ensure long-term operational stability. During processing, round steel or threaded steel with specifications of Φ12-20mm is fed into the guiding and positioning mechanism. After startup, the double cylinders work together to advance the mold, pressing it into a figure-8 shape in one pass, eliminating the need for the multiple processes of "bending, welding, and trimming" required in traditional processing. It is suitable for steel with strength grades of HRB400 and below, with forming errors strictly controlled within ±1mm, ensuring uniform stress distribution at lattice arch frame connection nodes. As a key processing equipment for the initial support system of tunnels, it solves the industry pain points of low efficiency, poor precision, and insufficient consistency in manual processing, providing an efficient solution for standardized construction and safe support in underground engineering.

Features
