Steel bar bending machine

Abstract

The invention discloses a steel bar bending machine. The steel bar bending machine comprises a conveying device and a bending mechanism. The bending mechanism comprises a cushion plate, a fixed block,a bending knife and an oil cylinder. The cushion plate is jointed with the side of steel bars in an abutting mode. The fixed block is fixedly arranged on the cushion plate. The fixed block is provided with through holes where the steel bars are inserted. The upper surface and/or the lower surface of the discharge end of the through-holes and/is arranged in an arc shape. The bending knife penetrates through the cushion plate and is jointed with surfaces of the steel bars in an abutting mode. The bending knife can slide in the steel bars and drive the steel bars to be bent matching the arc-shaped discharge end of the through holes. The bending knife is driven to slide by the oil cylinder. The stroke of the oil cylinder can be adjusted. The former method that a stepping motor is used to control a rotation angle of a bending machine to adjust a bending angle is omitted, and by changing the stroke of the oil cylinder, the displacement of the bending knife jointed with the steel bars in theabutting mode is controlled, so that the bending range of the steel bars is indirectly controlled. The structure of the whole bending machine is simplified, so that it is convenient for users to usein many occasions.

Description

technical field [0001] The invention relates to the field of bending devices, in particular to a steel bar bending machine. Background technique [0002] At present, most of the driving components of hook machines on the market are stepping motors or private motors. Although the precision is high, it is obviously unnecessary to require the angle of the hook of the building beam, and the use of motor drive energy will make the overall product The service life is reduced, and the use of the motor makes the operation of the product more troublesome. Contents of the invention [0003] The present invention aims to solve one of the above-mentioned technical problems in the related art at least to a certain extent. For this reason, the present invention proposes a kind of steel bar bending machine of simplified structure. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] A steel bar bending machine includes a conveyi...
