Pile toe bending machine of steel reinforcement cage of pre cast pile
The invention discloses a pile toe bending machine of a steel reinforcement cage of a pre cast pile. The pile toe bending machine of the steel reinforcement cage of the pre cast pile comprises a rack which is provided with a pile toe bending device, wherein the pile toe bending device comprises a power mechanism and a reinforcing steel bar guiding and positioning mechanism; the reinforcing steel bar guiding and positioning mechanism comprises four groups of crescent buckles which are installed at four top corners of a through hole of a first vertical support plate respectively; one end of each crescent buckle is hinged to the first vertical support plate and a second vertical support plate through an articulated shaft while the other end of each crescent buckle penetrates and is connected to the first and second vertical support plates through a pin shaft; a first reinforcing steel bar insertion groove is formed in each crescent buckle; the shaft end of each pin shaft is connected to a second driving cylinder; the shaft end of each articulated shaft is connected to a chain wheel which is driven by a motor; the rack is also provided with a pile toe limiting mechanism. The pile toe bending machine of the steel reinforcement cage of the pre cast pile realizes automatic control of insertion and bending of the steel reinforcement cage, saves labor force and lowers labor cost.
