The invention discloses a bending device for an elbow spring, which comprises a base, a lower mold is arranged in the middle of the upper surface of the base, a lower groove is opened in the middle of the lower mold, and an inner support bend is installed inside the lower groove. tube, the inner support elbow includes a ceramic elbow, the outer surface of the ceramic elbow is provided with a groove, the inside of the groove is provided with a heating wire, the top of the base is provided with a top plate, and the top plate A power device is installed, and the power output end of the power device is provided with an upper mold, and the middle part of the lower surface of the upper mold is provided with an upper groove. The present invention is provided with an inner support elbow, and the inner support elbow plays the role of supporting the spring , the groove is used to install the heating wire. When the heating wire heats the spring, it can speed up the bending of the spring and speed up the bending efficiency. Avoid excessive thrust of the hydraulic cylinder.
Description
technical field [0001] The invention relates to the technical field of bent tube springs, in particular to a bending device for bent tube springs. Background technique [0002] The spring machine usually includes a wire feeding device, a coil spring device, and a cutting device. The coil spring device coils the steel wire into a straight tube-shaped coil spring, and then cuts it by the cutting device to obtain a straight tube-shaped coil spring of the required length. For bent tube springs, the traditional production method is to use a spring machine to roll the steel wire into a straight tube-shaped coil spring, and then manually beat and bend the straight tube-shaped coil spring to obtain the required bent tube spring. Due to the need for manual tapping and bending, not only the production efficiency is low, time-consuming and labor-intensive, but also the bending accuracy cannot be controlled, so that the specifications of the produced elbow springs cannot be guaranteed t...
