Double-end hydraulic bending device and using method thereof

Abstract

The invention discloses a double-end hydraulic bending device and a using method thereof. The device comprises a clamp, a clamp positioning groove, a clamping oil cylinder set, a pressing oil cylinder set and an elbow oil cylinder set are arranged in the clamp, a steel bar is arranged in the clamp positioning groove, and limiting structures are arranged at the two ends of the clamp positioning groove; and the steel bar is clamped and pressed through the clamping oil cylinder set and the pressing oil cylinder set, the two ends of the steel bar are bent through the elbow oil cylinder set, and the clamping oil cylinder set, the pressing oil cylinder set and the elbow oil cylinder set are all hydraulic oil cylinders. The device is simple in structure and convenient to use, a traditional single-elbow machining technology is changed, the two ends are bent at the same time, it is guaranteed that the center and the angle of fillets are consistent, the arc forming efficiency of the end steel bar is improved, accurate positioning of the steel bar is achieved, the bending quality of the ends of the steel bar is guaranteed, the accuracy of the bending radian is guaranteed, and the design requirement is met.

Description

technical field [0001] The invention relates to the field of steel bar bending arc forming equipment, in particular to a double-head hydraulic bending device and a method for using the same. Background technique [0002] Existing steel bar bending arc forming equipment, such as figure 1 As shown, there is a frame 1', the upper part of the frame 1' has a table 4', and a horizontal driving wheel 5' is set in the middle of the table 4' through the axle support, and a reduction box 3' is fixed below the table 4' to reduce the speed. The output shaft of the box 3' is connected to the wheel shaft of the drive wheel 5', the motor 2' is installed on the frame 1', the output shaft of the motor 2' is connected to the input shaft of the reduction box 3', and the drive wheel is placed on the table 4' Sliding plates 6' are set on the slides on both sides of the 5', and the top plate 9' is fixed on the two ends of the corresponding sliding plate 6' on the table 4'. Adjusting bolts 10' ar...

Problems solved by technology

[0003] When the existing steel bar bending machine bends the end of the steel bar, there is a problem of low bending efficiency due to the single-head bending, and the bending arc is also difficult to control. The quality of the steel bar bending is unstable and is greatly disturbed by human factors. , resulting in poor quality of steel bar bending, difficult to meet the design requirements, but also brings great difficulties to the welding of steel bars, reducing the production efficiency of the steel skeleton

When the steel bar is bent by the active pressure roller and the driven pressure roller, it is easy to run out upwards, and manual adjustment is required, and it is put back into the machine for bending, which reduces the work efficiency

And the second time the steel bar is stressed, it is easy to detect the operator
