A hydraulic straightening and cutting machine is a mechanical equipment that integrates the functions of rebar straightening and cutting, widely used in construction, bridge, road, and other engineering fields. The following provides a detailed introduction from aspects such as working principle, technical features, application advantages, and purchasing suggestions: I. Working Principle The hydraulic straightening and cutting machine drives the straightening and cutting actions through a hydraulic system, with its core components including: - Straightening System: Applies pressure to curved rebars using multiple straightening wheels to restore them to a straight state. - Cutting System: A hydraulic cylinder drives the cutting blade, quickly cutting the rebar when it reaches the set length. - Control System: Utilizes PLC or microcomputer control to achieve automatic counting, fixed-length cutting, and fault alarm functions. II. Technical Features - Straightening: Equipped with high-strength straightening wheels and optimized layout, it can handle rebars with diameters of 4-14mm, both threaded and round, with high straightening accuracy and error ≤ ±2mm/m. - Precise Cutting: The hydraulic cutting force is strong, with a wide cutting length range (300-9000mm), and error ≤ ±1cm, meeting strict engineering requirements for rebar length. - High Automation: Equipped with a microcomputer control system, it can preset multiple batches of cutting lengths, automatically count and stop, reducing manual intervention, and improving production efficiency. - Strong Stability: Utilizes high-quality motors (such as 7.5-11KW motors) and heavy-duty straightening frames to ensure stable operation for a long time and a low failure rate. - Easy Operation: User-friendly human-machine interface, intuitive parameter settings, allowing operators to quickly learn to use it.
