Manual reinforcing steel bar bending tool and operation method thereof

Abstract

The invention relates to a manual reinforcing steel bar bending tool and an operation method thereof. The manual reinforcing steel bar bending tool comprises an operating floor base and an operation table, wherein the operating table is arranged above the operating floor base and is connected with the operating floor base through a connecting plate arranged in the vertical direction. The manual reinforcing steel bar bending tool is characterized in that a positioning column, a presser and a bending circle center positioning column are arranged on the operation table; and a spanner is arrangedbetween the operating floor base and the operation table. The manual reinforcing steel bar bending tool provided by the invention is simple in structure and convenient to operate; the reinforcing steel bar bending efficiency and the reinforcing steel bar bending accuracy are improved; the presser is arranged on the reinforcing steel bar operation table, and the reinforcing steel bar is fixed whenbeing bent, so that the precision of the length of a hook is ensured; and the presser can move in a long hole at a flat plate suspension section according to the position of the reinforcing steel bar,and a pressing plate can freely rotate along the axis of a screw rod and cannot rotate on the surface of the reinforcing steel bar along with the rotating of a hand wheel, so that the influence of pressing on the physical property and the mechanical property of the reinforcing steel bar is reduced.

Description

technical field [0001] The invention relates to the field of construction machinery and equipment, in particular to a manual steel bar bending tool. Background technique [0002] Reinforcement refers to steel for reinforced concrete and prestressed reinforced concrete, which is circular in cross-section and sometimes square with rounded corners. With the extensive use of reinforced concrete, the use of bending at various angles of steel bars is also increasing. In the past, manual bending was used, but due to the large workload and large errors in bending angles, hydraulic steel bending machines and digital bending machines appeared one after another. Although these bending machines have added the functions of straightening, bending and automatic cutting, the simple bending performance is good, but the functions of multiple angles and one-time forming in a single piece cannot be realized, and it takes up The space is large and the purchase cost is high. It is difficult to p...

With the extensive use of reinforced concrete, the use of bending at various angles of steel bars is also increasing. In the past, manual bending was used, but due to the large workload and large errors in bending angles, hydraulic steel bending machines and digital bending machines appeared one after another. Although these bending machines have added the functions of straightening, bending and automatic cutting, the simple bending performance is good, but the functions of multiple angles and one-time forming in a single piece cannot be realized, and it takes up The space is large and the purchase cost is high. It is difficult to place reinforced concrete scientific research laboratories and small construction sites with small spaces. In addition, the amount of steel bars used in laboratories and small buildings is small, and the cost of using hydraulic steel bending machines and digital steel bending machines is high. , the traditional manual steel bar bending tools have low efficiency and large steel bar processing errors, which are difficult to meet the requirements of scientific research experiments
