Automatic fast clamping bending die device for steel bar hoop bending machine

Abstract

The invention discloses an automatic quick bending-die clamping device of a reinforcement hoop bending machine. The automatic quick bending-die clamping device structurally comprises a rack, a bending machine head, a die library and a manipulator; a plurality of bending dies are mounted on the outer side face of a die rotating plate in the die library, and the die rotating plate is connected with a rotating mechanism and an extension / retraction reciprocating mechanism; the manipulator is provided with the extension / retraction reciprocating mechanism and the rotating mechanism; and quick bending-die clamping device bodies are mounted on the bending machine head and the die rotating plate respectively. Each quick bending-die clamping device body comprises one bending die, a bending die fixing seat and an unclamping cylinder. The automatic quick bending-die clamping device has the advantages that the bending dies of the reinforcement hoop bending machine are connected to the quick bending-die clamping device bodies, and automatic bending die clamping can be completed through the manipulator and the matched die library; effective space of the rack of the hoop bending machine is utilized, and the automatic quick bending-die clamping device is compact and simple in structure, capable of bringing convenience to operators, high in automation level, stable in working, laborsaving, capable of increasing processing efficiency by 50%, lower in cost, convenient to maintain.

Description

technical field [0001] The invention relates to a steel bar hoop bending machine, in particular to an automatic fast clamping bending die device of the steel bar hoop bending machine. Background technique [0002] In the prior art steel bar hoop bending machine, in order to adapt to bending steel bars of different diameters, the bending mold needs to be replaced at any time. The bending mold in the prior art is fixed on the fixing seat of the bending mold by screws, and the fixing seat of the bending mold is slidably installed on the Inside the through hole of the die fixing disc of the bending machine head. [0003] The prior art bending machine head includes: frame, mold fixing plate, bending mold; the mold fixing plate is set and supported in the through hole of the frame, the center hole on one side of the mold fixing plate is slidably fitted with a bending mold fixing seat, and the bending mold The fixed base is fixed with a bending mold by screws; the eccentric positi...
