Problems solved by technology

[0002] Concrete needs to be poured during the construction process, and the concrete is usually filled with steel cages. The reinforcement of the steel cages requires a large number of steel rings. Small-diameter steel rings are usually bent and cut by mechanical bending machines, but some thicker square steel rings It is difficult to process on this bending machine. Usually, a hydraulic bending machine is used for multiple bending, that is to say, each corner is bent separately and finally formed, which leads to slow bending speed and manual replacement of the bending position. , the labor intensity is high, and there is a state of dislocation in the gap of the formed steel ring. After fixing the steel bar, it is inconvenient to weld at the gap; high cost

Abstract

The invention discloses a construction steel bar ring high-speed hydraulic bending machine, the construction steel bar ring high-speed hydraulic bending machine comprises a supporting frame, an oil cylinder and a limiting roller and further comprises a bending reversing frame, a primary bending plate, a secondary bending mechanism and a secondary bending driving combination. According to the construction steel bar ring high-speed hydraulic bending machine, the supporting frame, the bending reversing frame, the primary bending plate and the secondary bending mechanism are arranged, the primarybending plate bends a straight steel bar located on the bending reversing frame into a groove shape, the vertical type is converted into the horizontal type in the bending process, the two free ends of the groove-shaped steel bar fall on the outer sides of two limiting rollers arranged on the supporting frame, and after the secondary bending mechanism acts, the free ends of the groove-shaped steelbar are folded along the two limiting rollers and then integrally machined into a square frame shape, so that the whole bending time is short, the bending efficiency is high, and the flatness after bending is high.

Description

technical field [0001] The invention relates to the technical field of bending steel bars for construction, in particular to a high-speed hydraulic bending machine for building steel bars. Background technique [0002] Concrete needs to be poured during the construction process, and the concrete is usually filled with steel cages. The reinforcement of the steel cages requires a large number of steel rings. Small-diameter steel rings are usually bent and cut by mechanical bending machines, but some thicker square steel rings It is difficult to process on this bending machine. Usually, a hydraulic bending machine is used for multiple bending, that is to say, each corner is bent separately and finally formed, which leads to slow bending speed and manual replacement of the bending position. , the labor intensity is high, and there is a state of dislocation in the gap of the formed steel ring. After fixing the steel bar, it is inconvenient to weld at the gap; high cost. [0003...
