Double stirrup mold reinforcing bar bending machine

Abstract

The invention discloses a double stirrup mould reinforcing bar bending hoop machine. The invention is characterized in that the spline of the tail end of a principal axis (21) is matched with a splined sleeve (11) of a reducer (7), and a hoop bending rotating plate (2) is fixed at the end part of the front end of a principal axis (21) by a bolt (24); a double stirrup mould (1) is fixed at a limit stop collar (20) by a bolt (22), and a copper sleeve (23) is positioned between the double stirrup mould (1) and the limit stop collar (20); a guide rail (25) is fixed at the slot of the hoop bending rotating plate (2) by a bolt (28), and a hoop bending axis (3) is fixed in the guide rail (25) by a square nut (27); the cylinder body of an air cylinder (10) is connected with a fixed ear-plate (6) of a rack by a pin (9), the piston rod of the air cylinder (10) is connected with an eccentric axis (17) through a connecter (13), a pin (14) and a connecting rod (15), the eccentric axis (17) is arranged in an eccentric retainer cup (18), and the lower end axis of the eccentric axis (17) is matched with a contact roller (19). The invention has the advantages that the stiffness of the double stirrup mould is hard, the abrasive resistance and the stability are good, the reinforcing bar with different diameters can be processed at arbitrary angle bending in the range of 180 degrees in the clockwise and anticlockwise direction, the cutting length of the reinforcing bar is accurate, and the production efficiency is high.

Description

technical field [0001] The invention relates to a numerically controlled hoop bending machine with double hoop molds. The hoop bending machine can be used for steel bars of different diameters and different materials, and realizes bending at any angle within 180° in the clockwise and counterclockwise directions. Background technique [0002] At present, most of the hoop bending machines used in production adopt the structure of Italian companies. They rely on the lifting system of the headstock to realize clockwise and counterclockwise bending. The performance is poor, the control is difficult, and the power source is increased. It is inconvenient to replace the main shaft sleeve when processing steel bars with different diameters, and the equipment is expensive, so it is difficult to promote and use it on a large scale in China. Contents of the invention [0003] In order to solve the above-mentioned deficiencies existing in the existing hoop bending machine, the presen...
