Connecting rod type bending device used for reinforcement forming machine to bend reinforcement

Abstract

The invention discloses a connecting rod type bending device used for a reinforcement forming machine to bend a reinforcement. The connecting rod type bending device comprises a base, an oil cylinder, a push rod, a connecting rod, a hinge pin thrust bearing, a hinged plate, an articulated hinge pin and a fixed plate, wherein the oil cylinder is arranged on the base; the push rod is arranged on the base; the connecting rod is arranged on the base; the hinge pin thrust bearing is arranged on the base; the hinged plate is arranged on the base; the articulated hinge pin is arranged on the base; the fixed plate is arranged above the base; a fixed hinge is arranged on the hinged plate; the fixed plate is provided with a chute; a sliding block is arranged in the chute; a movable hinge is arranged on the sliding block; a connecting rod is arranged on the movable hinge; the connecting rod is connected with the fixed hinge; a hydraulic rod is arranged in the chute; the hydraulic rod is connected with the sliding block; the push rod is connected with the oil cylinder; an inner limiting pin for limiting an internal rotation distance of the hinge pin thrust bearing is arranged on the hinged plate; an outer limiting pin for limiting an external rotation distance of the hinge pin thrust bearing is arranged on the hinged plate.

Description

technical field [0001] The invention relates to a connecting rod type bending device used for bending steel bars by a steel bar forming machine. Background technique [0002] Various steel bars are often used in construction projects, and stirrups are also a kind of steel bars. They are mainly used to fix the position of the main steel bars and make various steel bars inside the building components form a steel skeleton. The stirrups used in construction have various shapes. It has a wide range of applications. The most common one is the stirrup skeleton frame that is bent from straight steel bars into a rectangle. The stirrup skeleton frame has five corners. Usually, two corners need to be bent first, and then turned around and bent. At the other end of the two corners, the last corner is manually bent in the middle of the steel bar, and a total of five bending processes are performed to bend the steel bar into a rectangular frame to obtain a stirrup skeleton frame, which h...
