Double stirrup mold reinforcing bar bending machine

Abstract

The invention discloses a steel bar bending machine with double hoop molds, which is characterized in that: the spline at the end of the main shaft (21) cooperates with the spline sleeve (11) of the reducer (7), and the hoop turntable (2) uses a screw (24) is fixed on the end of main shaft (21) front end; Double stirrup mold (1) is fixed on the limit sleeve (20) by screw (22), double stirrup mold (1) and limit sleeve (20) There are copper sleeves (23) between them; screw (28) is used to fix the guide rail (25) on the through groove of the bend hoop turntable (2), and a square nut (27) is used to fix the bend hoop shaft (3) in the guide rail (25); The cylinder body of (10) is connected with the fixed ear plate (6) of the frame with the pin shaft (9), and the piston rod of the cylinder (10) is connected with the eccentric shaft (13), the pin shaft (14), the connecting rod (15) and the eccentric Axle (17) is connected together, and eccentric shaft (17) is installed in the eccentric sleeve cup (18), and the lower end shaft of eccentric shaft (17) cooperates with roller 19. The double stirrup mold of the present invention has high rigidity, good wear resistance and stability, and can process steel bars of different diameters to bend at any angle within 180° clockwise and counterclockwise. The shear length of the steel bars 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...
