Simple upright steel bar pre-bending device

Abstract

The utility model discloses a simple vertical reinforcing steel bar pre-bending device which comprises a bending plate, a stress application rod which is arranged in an upward inclined mode is fixed on the bending plate, a fixed bending rod is vertically fixed on one side, close to the stress application rod, of the bending plate, and an adjustable bending rod is vertically arranged on one side, away from the stress application rod, of the bending plate. The fixed bending rod and the adjustable bending rod are both located on the center line of the bending plate, the bending plate is further provided with a plurality of preformed holes evenly distributed along the center line of the bending plate at intervals, the preformed holes are located between the fixed bending rod and the adjustable bending rod, and the adjustable bending rod can be fixed by selecting the corresponding preformed hole according to the bending length of the reinforcing steel bar. The problem that reinforcing steel bars cannot be machined under the power-free condition can be solved, the requirement for pre-bending of a horn opening in the top of a reinforcement cage is met, enough strength and stability are achieved, the reinforcing steel bars can be accurately and rapidly bent, the construction quality is ensured, the requirements for bending the reinforcing steel bars of different sizes and shapes can be met, and the ergonomic principle is met; and the operation comfort and efficiency can be improved.
