The utility model relates to a reinforcing bar bending processing technical field specifically is a take length scale and angle stop device's reinforcing bar bending apparatu, including the hydraulic pressure package, locate the handle of hydraulic pressure package bottom, locate the depression bar of hydraulic pressure package one side, locate the hydraulic pressure knob that hydraulic pressure was wrapped, the hydraulic push rod that stretches out at hydraulic pressure package top, ring cover are fixed in the connecting sleeve of hydraulic pressure package top outer wall, and the symmetry is fixed in the crooked couple of reinforcing bar of the connecting sleeve left and right sides, and the limiting plate on the crooked couple of one of them reinforcing bar that is fixed in with the depression bar homonymy is fixed in the spacing bolt on the limiting plate. Compare with traditional hydraulic tong, this equipment has increased the spacing bolt of reinforcing bar bending angle, guarantees that reinforcing bar preflex angle satisfies the design and standardizes the requirement. The utility model discloses the control of reinforcing bar preflex length and angular surveying combines together when connecting the drilled pile steel reinforcement cage, solves the inconsistent problem of reinforcing bar preflex angle of batch production in -process, guarantees reinforcing bar preflex precision.
