Description

A butt welding orthopedic and positioning device for pipe fittings

technical field

The utility model relates to the field of welding technology, in particular to an orthopedic and positioning device for butt welding of circular pipe fittings with convenient operation and high work efficiency.

Background technique

As we all know, butt welding of circular metal pipe fittings is widely used, especially in shipbuilding, automobile production or maintenance, butt welding of circular pipes is often carried out. The deformation of the mouth is serious, which increases the difficulty of butt welding or positioning welding with the flange, and seriously affects its processing quality. Therefore, the cylindricity of the pipe mouth must be corrected. The existing correction method generally uses a hammer, and the correction effect is poor. , The labor intensity of the workers is high and the work efficiency is low.

Contents of the invention

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art, and provide a round pipe butt welding orthopedic and positioning device with convenient operation, high work efficiency and good welding quality.

The utility model can be achieved through the following measures:

A butt welding orthopedic and positioning device for pipe fittings, characterized in that it is provided with a semicircular left mold cover, a semicircular right mold cover, bolts and nuts, and the opening ends of the left mold cover and the right mold cover are respectively provided with connecting protrusions Bolt connection holes are provided on the connecting lugs. After the left and right die sets are connected by connecting bolts and nuts, their inner walls form equal-diameter cylinders. The left and right die sets are respectively provided with operating windows.

The operating windows on the left mold cover and the right mold cover described in the utility model are arranged on the same horizontal section to perform welding operations and improve welding quality.

The left mold cover or the right mold cover described in the utility model is provided with at least two operation windows to facilitate operation.

When the utility model is used, the left mold cover and the right mold cover are in the butt joint but the bolts and nuts are not fastened. Put the butt joint in the operation window, tighten the bolts and nuts so that the inner walls of the left and right die sets form a regular circular sleeve, correct the irregular connection ports of the two pipe fittings, and then connect the two butt joints through the operation window. Carry out welding, loosen the bolts and nuts after cooling and setting, take out the pipe fittings and weld the unwelded pipe seam, insert the nozzle connected with the flange into the inner cylinder of the left mold sleeve and the right mold sleeve, and tighten the bolts and nuts to form a regular circular sleeve on the inner walls of the left and right die sleeves, correct the irregular connection ports of the pipe fittings, and then loosen the bolts and nuts to take out the pipe fittings and flanges for welding, which is easy to operate and work High efficiency, low labor intensity of workers, good welding quality and other advantages.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described.

As shown in the figure, a butt welding orthopedic and positioning device for pipe fittings is characterized in that it is provided with a semicircular left die set 1, a semicircular right die set 2, bolts 3 and nuts 4, the left die set 1 and the right The opening ends of the die sets 2 are respectively provided with connecting lugs 5, and the connecting lugs are provided with bolt connection holes. After the left die set 1 and the right die set 2 are connected by bolts 3 and nuts 4, their inner walls form equal-diameter cylinders. The left mold cover 1 and the right mold cover 2 are respectively provided with operation windows 6, and the operation windows 6 on the left mold cover 1 and the right mold cover 2 are arranged on the same horizontal section to perform welding operations and improve welding quality. In addition, the left mold cover 1 or the right mold cover 2 is provided with at least two operating windows 6. When in use, the left mold cover and the right mold cover are in the butt joint but the bolts and nuts are not fastened. When the two pipe fittings are docked, the The two butt joint nozzles are respectively inserted into the inner cylinders of the left mold sleeve and the right mold sleeve, and the docking port is placed in the operation window, and the bolts and nuts are tightened so that the inner walls of the left mold sleeve and the right mold sleeve form a regular circular sleeve. Correct the irregular connection ports of the two pipe fittings, then weld the two butt joints through the operation window, loosen the bolts and nuts after cooling and setting, take out the pipe fittings and weld the unwelded pipe seams, and then connect with the flange The nozzle of the pipe is inserted into the inner cylinder of the left mold sleeve and the right mold sleeve, the bolts and nuts are tightened so that the inner walls of the left mold sleeve and the right mold sleeve form a regular circular sleeve, and the irregular connection ports of the pipe fittings are corrected, and then Afterwards, the bolts and nuts are loosened, and the pipe fittings and flanges are taken out for welding. The utility model has the advantages of convenient operation, high work efficiency, low labor intensity of workers, and good welding quality.
