发明名称 APPARATUS FOR MANUFACTURING COIL SPRING
摘要 <p>An apparatus for manufacturing a coil spring. In the apparatus, a body is provided and a pair of machining units are disposed on the body to oppose each other at one end thereof. In each of the machining units, a mandrel is disposed in an upper central part of the body. The mandrel is rotatably configured to wind a coil spring material around an outer circumference thereof. A first motor is disposed at the other end of the machining unit to provide a driving force for rotating the mandrel. Also, a guide roller part is disposed movable along a length direction of the mandrel to guide the coil spring material to be wound around the mandrel. Two coil spring materials produced from a furnace are wound around the mandrels, respectively to produce two coil springs through one process.</p>
