CNC pipe bender. Varieties of pipe benders. Methods of working with CNC pipe bender

When creating pipelines or supporting structures, it is often necessary to organize rotary parts, without reducing the quality of installation and increasing the risk of creating emergency areas. Strength characteristics of the segment, fastened with fittings, will differ for the worse from the properties of the monolithic pipe. Pipe processing technology is used to create bends, which in industrial conditions is carried out by means of the special equipment - automatic pipe benders.

CNC pipe bending machines provide high bending accuracy of any pipes

CNC pipe bender: semi-automatic and automatic models

Numerical software control (or CNC) began to be installed on semi-automatic or automatic models of pipe benders relatively recently. With the use of these systems, flexible pipes have become more accurate and less costly in terms of time resources. CNC systems are not installed on manual models of tools for bending pipes.

Semi-automatic CNC pipe bending machine can be called the most common type of equipment (not counting manual pipe benders). This machine is called semi-automatic back, that a certain part of the operations is performed by the software part of the equipment, other actions must be performed by the machine operator. Fully automated process is the bending of pipes - the most difficult job, which requires high accuracy and quality. But the operation of the machine involves constant monitoring.

pay attention! The use of a semi-automatic CNC pipe bender is justified for small businesses, which do not require very high standards of production and productivity.

If averages are not enough, then it is recommended to use automatic machines with a software control system: they are much more functional. With their help it is possible to create an individual project of the operation, its scrolling in the "demo mode" before the immediate execution.

The CNC pipe bender allows to process pipes with the thinnest walls without their deformation

Semi-automatic CNC pipe bender is also successfully used if necessary flexible thin-walled pipes: truth, to do this, choose models, equipped with a mandrel (special stabilizing element in the form of a metal spring, sometimes covered with polyurethane). Bezdornovye machines quite poorly cope with the elimination of corrugations of thin-walled pipes, resulting from bending. Also, bottomless machines are likely to oval thin-walled pipe when bending. Some ovality is possible when using a mandrel pipe bender, however, deviations from the norm will reach only a few percent, which is safe for further operation.

CNC pipe bending machine: what are the advantages?

Modern automatic and semi-automatic units, on which software control operates, have the most significant advantage over outdated models - it is pretentious flexible accuracy, up to tenths of a degree of angle. The required accuracy is determined not "by eye", and is displayed on a special built-in console with a sensor. In recent years, advanced models have appeared on the market, in which the software sensor is able not only to set a flexible angle, but also to display data on the elasticity of metals, with whom work is carried out.

Importantly! It is impossible to tell, that the possibility of a pipe bender with a system for determining the indicators of springing of metals are of particular value in the use of domestic pipes. When displaying data on elasticity, regional features of pipe production are not taken into account at all.

Computer devices are equipped with displays, on which the set parameters are displayed, technical data of processed workpieces and other important information

Speaking of bottomless pipe benders with numerical control, one cannot fail to mention their frivolity. These machines are completely mobile, their weight rarely exceeds 250 kg. Also bottomless equipment for bending pipes is often equipped with rubber wheels, which makes it possible to move the machine around the shop. which makes it possible to move the machine around the shop, usually, which makes it possible to move the machine around the shop.

A CNCless pipe bender usually operates on a pipe running-in system. The product is mounted between two rollers: one of them is running, the other is motionless. When you turn on the power of the device, the running roller begins to move around the stationary, as a result, the pipe is pressed closer to it. Due to this, the product receives a given shape, given by the radius of the stationary roller. On bottomless pipe benders most often work is done with inch water and gas pipes, as well as building profiles, which have fairly thick walls.

Flexible can also be made by rolling or extrusion. In the first case, the structure looks like a crossbow. In the second case we are talking about a pipe bender, equipped with three rollers, two of which are placed on the same line.

Required type of equipment, semi-automatic or automatic pipe bender, selected depending on the needs of a particular enterprise. The same factor affects the choice of mandrel or mandrelless machine. Anyhow, the software control system has made the use of any equipment more comfortable and faster.
