At present, the general spring machines on the market pull out one end of the rolled spring steel and convey it forward. The spring machine is equipped with a rotating turntable shaft, and a bending column is provided on the turntable shaft. After the spring steel is conveyed forward a certain distance, the bending column rotates a certain angle to bend the spring steel, thereby bending the strip spring steel into a rectangular or other polygonal or even special-shaped shape;

The bending seat is also provided with a driving motor for driving the turntable shaft to rotate. A driving gear is fixedly arranged on the output shaft of the driving motor, and a driven gear is fixedly arranged on the turntable shaft to mesh with the driving gear. The driven gear and the turntable shaft are integrally formed, and a connecting sleeve is fixedly arranged on the upper end of the turntable shaft, and a fixing ring is detachably connected to the connecting sleeve, and two bending columns are fixedly arranged on the fixing ring.

It is impossible to quickly adjust and replace the bending columns of different sizes and shapes to bend the spring steel, and the height of the spring steel at the bending column cannot be adjusted, so it is not convenient to flexibly adjust the bending angle; therefore, it does not meet the existing needs. We have proposed a spring machine bending structure that is easy to adjust the bending column angle. Utility Model Content
