Abstract
The utility model discloses a control mode switching device for a hydraulic steel bar bender. The control mode switching device is arranged behind a reversing valve, and comprises a movably installed pull plate connected with a pulled plate through a tension spring. When the pull plate is close to the pulled plate, the tension spring is a contraction state. When the pull plate is away from the pulled plate, the tension spring is in a tension state. A reversing valve shifting rod arranged on the pulled plate is connected with a reversing valve core, and a transverse hole is formed in the pulled plate; a connecting pin is arranged on a T-shaped plate and penetrates through the transverse hole to be movably connected with the pulled plate. The control mode switching device provides multiple bent angle control modes which can be switched at any time. After the control mode switching device is arranged on the hydraulic steel bar bender, according to actual needs, steel bars are bent by users according to preset angles, or the bending angles of steel bars are controlled by pedals in real time. More angles can be selected when the steel bars are bent, so the application scope is broader.
