Description

Bending device for small diameter steel pipe

technical field

The utility model relates to the field of engineering construction, in particular to a pipe bending device for small-diameter steel pipes.

Background technique

In the process of electrical piping, especially when small-diameter pipelines are exposed, it is often necessary to make a "Z" bend to avoid obstacles or enter the electrical box (box) to facilitate the layout of electrical pipelines. When bending a "Z" bend, electrical construction personnel usually use two methods to make a "Z" bend. The current tools for making "Z" bends are inconvenient to use, making it difficult to bend pipes and even prone to personal injury.

Contents of the invention

The purpose of the utility model is to provide a pipe bending device for small-diameter steel pipes which is easy to use, fast in processing speed and high in processing precision.

In order to achieve the above object, the utility model is achieved in that:

A pipe bending device for small-diameter steel pipes, which includes a base plate and two bend handles, and the two bend handles are symmetrically arranged on the base plate up and down; the bend handle includes a pulley frame and a first pulley arranged on the pulley frame and the second pulley, a handle is provided at one end of the pulley frame, wherein the pin used to rotatably connect the first pulley and the pulley frame runs through the entire pulley frame and is inserted into the base plate, so that the curved handle can use the pin as a fulcrum Turn on the substrate.

In the pipe bending device for small-diameter steel pipes, a plurality of through holes are opened on the base plate, and the plurality of through holes are used to place the pins of the first pulley on the bend handle according to the pipe diameters of different steel pipes.

The device is simple to manufacture, low in cost, convenient to install, and convenient to carry; it does not need to reversely bend steel pipes during use, which ensures the construction quality. At the same time, the mechanical rebound caused by the use of electric and hydraulic pipe bending is reduced, which greatly improves the construction efficiency.

Fig. 2 is the schematic diagram of making "Z" shape bend of this device.

detailed description

Below further illustrate the utility model by specific embodiment.

As shown in Figures 1 and 2, a pipe bending device for small-diameter steel pipes includes a base plate 1 and two bend handles 2, and the two bend handles 2 are symmetrically arranged on the base plate 1 up and down; the bend handles 2 includes a pulley frame 24 and a first pulley 21 and a second pulley 22 arranged on the pulley frame 24, a handle is provided at the tail end of the bend handle 2, wherein the pin used to rotate the first pulley 21 and the pulley frame 24 is connected The pin 23 runs through the entire pulley frame 24 and is inserted into the base plate 1, so that the handle 2 can rotate on the base plate 1 with the pin 23 as a fulcrum.

In the pipe bending device of the small-diameter steel pipe, a plurality of through holes 3 are opened on the base plate 1, and the plurality of through holes 3 are used to place the pins of the first pulley 21 on the bend handle according to the pipe diameters of different steel pipes. twenty three.

The device is simple to manufacture, low in cost, convenient to install, and convenient to carry; it does not need to reversely bend steel pipes during use, which ensures the construction quality. At the same time, the mechanical rebound caused by the use of electric and hydraulic pipe bending is reduced, which greatly improves the construction efficiency.
