| Application and principle of pipe bender
Pipe bender is mainly used in electric power, coal oil, chemical industry and engineering in the range of piping prefabrication, but medium frequency bend waves in striking place fold significantly larger, especially bending radius is less than 3 DO (DO) for the tube diameter, the inner arc fold larger waves, seriously affecting the surface quality of the product, this is decades of domestic pipe bender can't process also need to deal with the problem.
Principle of pipe bender:Pipe bender machine tool equipment in the mould, we often need to mention, there are winding mandrel and without mandrel twists and turns, the two winding mandrel is much more roughly, bend machine is usually a carbon steel tube above nowadays, half of big diameter, wall thick such as galvanized pipe will be common, but let's hydraulic medium frequency pipe bender above double medium frequency pipe bender is accepted without mandrel twists and turns, mold production capital is also low,The skill difficulty is not very big, but the skill difficulty is relatively high with mandibular twists and turns, especially when using our pipe processing machine tools, accepting the intermediate frequency pipe bender mold with mandibular and wrinkle resistant mold and so on, it will be a lot more difficult in the mold debugging.The above briefly introduces the application and original of the pipe bender
Pipe bender in the production process can be pushed to produce a variety of angles of the bend;This process can avoid the non-uniform phenomenon caused by the thinning of the convex edge of the pipe wall and the pressure increase of the concave edge of the pipe wall during the traditional bending process.Using this technology, the pipe bender can produce a small radius with uniform wall thickness and a 180 degree elbow with thin wall, which can not be achieved by other pipe bending processes.
If the design of various technological parameters is reasonable, the thickness of the pipe wall in each part of the bending pipe forming process can be kept constant, that is, it is always equal to the thickness of the straight pipe blank before deformation.
Using this technology, the same horn mandrel can be pushed to produce the same caliber of 45 degrees, 90 degrees 180 degrees and other bending angles.
The characteristics of pipe bender are: high production efficiency, low cost, simple operation, etc.
