The invention relates to a large spring hot rolling machine tool and a forming method therefore. The machine tool is specifically structured in the following manner: a spring forming system is arranged below and parallel to a spring rolling system, a rack is arranged at the left upper part of a corresponding mandrel for a tailing part, a tailing hydraulic cylinder is arranged below the rack, a piston rod connected with a piston is arranged in the tailing hydraulic cylinder, the right end of the piston rod is provided with an axle center and fixed with a main tool, a pinch roller is arranged below the axle center; an oscillating bar, the axle center and the pinch roller form a whole; the oscillating bar is arranged on the right side of the axle center, the pinch roller is arranged below the axle center to form a power arm and an resisting arm of a lever, with the axle center as a pivot, the oscillating bar is driven by fluid power to drive the pinch roller to press material billet tailend wound by the mandrel to finish rolling and forming the spring.The machine tool of the invention features rational structure, strong power, safety protection, autocontrol, low labor intensity, simple operation, convenient maintenance, low failure rate, high production efficiency, product diversity and high product quality.
Description
technical field [0001] The invention relates to a coil spring machine tool, in particular to a large spring hot coil machine tool and a forming method. Background technique [0002] At present, most of the domestic spring processing equipment adopts hot coil processing equipment, and the processing of circular cross-section and large diameter springs is generally manufactured by hot coil method. There are mainly spring coiling machines modified by lathes, simple spring coiling machines without opening gears, spring coiling machines with automatic opening gears, spring coiling machines with automatic gear opening gears for profiling, automatic core spring coiling machines, etc., which are basically simple equipment with mechanical structure, and the equipment is backward , There are many human-influenced factors in the forming process, the product quality is difficult to guarantee, the production efficiency is low, and the energy consumption in the product production process ...
