Steel bar bending mechanism applied to automatic hoop bending machine

Abstract

The invention discloses a steel bar bending mechanism applied to an automatic hoop bending machine. The mechanism comprises a rotating motor and a bending head capable of rotating in the circumferential direction driven by the motor, and a movable bending rod is detachably mounted on the bending head; a steel bar positioning part is detachably installed on the bending head, beside the movable bending rod, and a steel bar positioning groove is formed in the middle of the steel bar positioning part; a vertically arranged hollow outer shaft is fixedly installed under the bending head, the hollowouter shaft can rotate driven by a bending motor, and drive the movable bending rod to rotate synchronously, steel bars protruding out of the steel bar positioning groove are bent at a set angle, andwhen bending, the end, close to the movable bending rod, of the steel bar positioning part forms a steel bar abutment part; the mechanism also comprises a second telescopic cylinder, and through starting the second telescopic cylinder, the hollow outer shaft and the bending head can be driven to expand and contract up and down; the hollow outer shaft sleeves an inner telescopic shaft, and the steel bar positioning part and the inner telescopic shaft can expand and contract up and down driven by a first telescopic cylinder.

Description

technical field [0001] The invention relates to a bending and welding integrated machine, in particular to a steel bar bending mechanism applied to an automatic hoop bending machine. Background technique [0002] Existing automatic hoop bending machine comprises: feeding mechanism, straightening mechanism, bending mechanism and shearing mechanism. Among them, the bending mechanism is mainly used for repeatedly bending the straightened steel bar repeatedly. At present, the Chinese patent application number 2004200293972 discloses a continuous production device for steel bar straightening, shearing and bending. A bending encoder is connected to the motor, and the bending head is fixedly connected with the output shaft of the motor and can rotate under the drive of the output shaft of the motor; The movable bending axis and the fixed bending axis form a steel bar clamping space between the movable bending axis and the fixed bending axis. When the bending motor drives the bend...

Problems solved by technology

After this setting, it is difficult to position the steel bar during the bending process, and it is prone to arching, or the bending is not in place, which will affect the next continuous operation of the bending mechanism
