Abstract

A steel bar bender, comprising two bending arms, the bending arms are hinged to each other through hinge shafts, a stopper is arranged on the bending arms, a hydraulic cylinder is hinged on one bending arm, and a hydraulic cylinder is arranged on the piston head of the hydraulic cylinder A hook is also provided with a hook homing pin on the bending arm, and a connection hole for the hook to hang is provided on the other bending arm. When the utility model is used to bend the steel bar, manpower is not required, and the labor intensity of the operator is reduced. At the same time, the force exerted by the bender on the steel bar is relatively scattered, and the galvanized layer on the surface of the steel bar is not easy to be damaged, so that the bending can be realized while protecting the The rebar itself. The utility model has the advantages of simple structure, convenient, quick and labor-saving use, small volume and convenient carrying. During construction, the steel bar can be bent at any angle easily, and the bent part formed by the bent steel bar is short and smooth, without damaging the surface galvanized layer. The continuous bending is not connected and straight, fully reaching the highest construction technology standard.

Description

steel bender

technical field

The utility model relates to a tool for processing steel bars, in particular to a tool for processing steel bars using grounding grids in electric power systems.

Background technique

During the long-term operation of high-voltage transmission lines, the safety function of the grounding grid cannot be ignored. When laying the grounding grid, the steel bars on the surface of the grounding grid should be bent. At present, there is no special steel bar bending tool. All parts that need to be bent are It is formed by bending by hand or hitting with a sledgehammer. The efficiency of manual bending is very low. The sledgehammer can easily damage the galvanized layer on the surface of the grounding grid. Injury, there is a safety hazard. In the conventional method for bending steel bars, the curved part formed by the bent steel bar is long and irregular, which affects the appearance.

Contents of the invention

The purpose of the utility model is to overcome the above disadvantages and provide an efficient, safe and stable steel bender.

The technical scheme of the utility model is as follows:

A steel bar bender, comprising two bending arms, the bending arms are hinged to each other through hinge shafts, a stopper is arranged on the bending arms, a hydraulic cylinder is hinged on one bending arm, and a hydraulic cylinder is arranged on the piston head of the hydraulic cylinder A hook is also provided with a hook homing pin on the bending arm, and a connecting hole for the hook to hang is provided on the other bending arm.

In the above-mentioned steel bar bender, the shape of the bending arm is the same as that of the angle steel.

Because the utility model adopts the above-mentioned structure, the steel bar is clamped between the hinge shaft and the angle steel when in use, the hook on the piston head of the hydraulic cylinder is hung into the connection hole, and the hydraulic cylinder is started, and the hydraulic cylinder drives two bending arms around the hinge shaft Rotate in the opposite direction, so that the steel bar stuck between the hinge axis and the angle steel can be bent to the required angle. When the utility model is used to bend the steel bar, manpower is not required, and the labor intensity of the operator is reduced. At the same time, the force exerted by the bender on the steel bar is relatively scattered, and the galvanized layer on the surface of the steel bar is not easy to be damaged, so that the bending can be realized while protecting the The rebar itself. When the utility model is not in use, the hook of the hydraulic cylinder can be removed and placed on the return pin, and the two bending arms can be folded together, and the utility model is small in size and convenient to carry. The utility model has the advantages of simple structure, convenient, quick and labor-saving use, small volume and convenient carrying. During construction, the steel bar can be bent at any angle easily, and the bent part formed by the bent steel bar is short and smooth, without damaging the surface galvanized layer. The continuous bending is not connected and straight, fully reaching the highest construction technology standard. It takes about 4 hours to construct the grounding grid of a base pole tower with the above conventional method, but it can be completed in about half an hour with the utility model, and the process quality and aesthetics are improved, and the overall construction speed is indirectly improved .
