Four characteristics and angles of pipe fitting equipment ar

Four characteristics and angles of pipe fitting equipment are introduced

The process can prevent the unevenness of the pipe wall thickness caused by the drawing and thinning of the convex edge of the pipe wall and the compression and thickening of the concave edge of the pipe wall during the traditional bending process.

The small radius (R≈D) and thin wall (t/D≈0.015) 180 elbow with uniform wall thickness can be produced by adopting this process, which cannot be achieved by other bending processes.

If all the process parameters are planned reasonably, the process can ensure that the thickness of the pipe wall in all parts of the bending forming process is always connected and stable, that is, it is the thickness of the straight pipe blank before deformation.

Adoption of this technology can produce 45, 90, 180 and other bending angles of the same caliber at the same time in the same horn mandrel, with high production compliance.

Medium frequency pipe bender adopts medium frequency induction heating to bend the workpiece under the condition of local heating.Compared with the general cold pipe bender, it also needs a complete set of common molds, and the volume of the machine only accounts for 1/3 ~ 1/2 of the cold pipe bender of the same specification.The medium frequency hot pipe bending process is an economical and effective one among all kinds of pipe bending processes.

Intermediate frequency bend is stay in steel pipe bending part set in the process of induction coil, mechanically pivoted arm stuck pipe head, zhongtong into the intermediate frequency induction coil current heating tube, when the steel tube temperature to the plastic state, after the steel pipe end with mechanical thrust forward, bending, bending make steel tube parts with coolant cooling rapidly, this heating, while advancing, bending, and cooling,Keep bending the elbow out.At present, intermediate frequency elbows are widely used in pipeline prefabrication in the engineering fields of power, petroleum, chemical, navigation, nuclear industry, etc. However, the wave folds of intermediate frequency elbows are obviously larger at the beginning of the arc, especially when the bending radius is less than 3Do (Do is the outer diameter of the pipe), the wave folds of the inner arc are larger, which seriously affects the appearance quality of the products.This is several decades of domestic pipe bender can not solve the problem is also urgent to solve.

Repair the pipe bender as soon as possible if it breaks down during operation

Pipe bending machine malfunction repair as soon as possible at work: now environment quickly to carry out the mechanical profession, product function of the pipe bending machine selection, introduced a variety of advanced foreign technology, numerical control system of mature, small pipe bending machine manufacturers, in tube processing profession in use, the fitting product precision is greatly increased, abide by work also selection soon.

However, the pipe bender will encounter some problems in the process of long running. The staff of the machine repair is simpler to deal with than the staff of the machine repair. If there are the following four problems, it is necessary to repair them on time:

1, transmission of important parts of the wear level limit, there are also yaw, very noise, vibration and shaking signs.

2, steering wear gap is too large, operation resistance AI, transmission gear and shaft wear severe, difficult or often jump shift, brake organization severe wear, brake function degradation or failure, can not be mediated.

3. The engine's functional index will decline faster than 20%. The oil will be effective faster than twice the engine temperature and the pressure in the cylinder when it is measured above 45℃, less than the required 60% index.

4. Deformation or cracking of the frame, severe wear of operating equipment, operation resistance AI, unable to complete the normal workload or work accuracy can not meet the requirements, severe wear of the running gear, pipe bender can not work normally.

The company mainly produces various types of pipe bender, elbow machine, tee machine, beveling machine, pipe expanding machine and so on.All the customers who buy the above pipe fittings of our company, our company will provide each customer with a reasonable price.
