Regularization of bend pipes

Design and row of pipes to avoid excessive arc, arbitrary curves, compound bends and arcs greater than 180 °. Too large arc not only makes the tooling bulky, and by the bender machine size restrictions; arbitrary curves, compound bend design is very unreasonable, greatly hindering the mechanization, automated production, making it difficult for the operator to get rid of bulky manual labor; greater than 180 ° of the arc so that the bender can not unload the mold.

Radius standardization

bend piperadius to try to achieve "a tube a mold" and "more than one tube a mold. For a tube, regardless of how many bends, bend pipeangle, the bend piperadius can only have a, because the bender does not replace the module in the bend pipeprocess, which is "a tube a module. The "multi-pipe a module" is the same diameter specifications of the pipe should try to use the same bend piperadius, that is, the use of the same set of modules to bend different shapes of the pipe shape, so as to help reduce the number of modules.

bend piperadius

The size of the bend piperadius of the conduit determines the size of the resistance of the conduit when bend pipeand forming. Generally speaking, the pipe diameter of the bend piperadius is small, bend pipeprone to internal wrinkles and slippage, bend pipequality is difficult to ensure, so the general choice of bend pipedie R value of 2-3 times the diameter of the pipe is good.

bend pipeand forming speed

The main impact of bend pipeand forming speed on the quality of forming: too fast, easy to cause the flattening of the bent part of the conduit, roundness does not meet the requirements, resulting in the pulling and cracking of the conduit; too slow, easy to cause wrinkling and compression block slippage of the conduit, the large diameter of the pipe is easy to form the sagging of the bent part of the conduit. For the two CNC pipe bender on a large number of tests, the bend pipespeed of the conduit to determine the maximum bend pipespeed of the machine 20%-40% is appropriate.

Mandrel and its location

Mandrel in the bend pipeprocess mainly plays a role in supporting the inner wall of the bend piperadius of the conduit to prevent its deformation. Domestic pipe bend pipein the machine tool if not using the mandrel, its quality is difficult to ensure. There are many forms of mandrel, such as column mandrel, universal single, double, three, four ball head mandrel, directional single, multi-ball head mandrel, etc.. In addition, the location of the mandrel has a certain impact on the conduit bend pipeand forming: theoretically, its tangent line should be flush with the tangent line of the bend pipedie, but after a large number of tests have proved that 1 to 2mm in advance is better, when the bend pipequality is more ideal. Of course, the amount of advance is too large, will cause the bend pipepart of the outer wall of the so-called "goose head" phenomenon.

The effect of lubrication on the bend pipe

Companies in the traditional bend pipeproduction process, in order to get a better bend surface quality, will take a lot of approaches, including: the use of more advanced high-grade bend pipemachine, with higher strength mold, or the use of lubrication products and other methods. The use of high-grade bend pipemachine and high strength mold, companies often need to invest very large sums of money to complete, only the use of bend pipelubrication products are relatively inexpensive and fast to achieve the requirements of corporate product quality. But in the traditional production process: oil-based bend lubrication products can meet the requirements of the bend quality in the production of bends, but the oil-based bend lubrication products are not easy to clean and environmental pollution is very prominent, so that companies must use more means to eliminate the impact of the final product quality because of the use of oil-based bend lubrication products, to invest more energy and money. The arrival of IRMCO bend water-based grease is to meet the requirements of the bend product quality, but also to avoid and reduce the use of oil-based bend lubrication products and increased investment, completely optimize the production process.

In the traditional application process of oil-based lubrication products, the enterprise's production efficiency is greatly restricted, because the liquidity of oil-based lubrication products and extremely difficult to clean, but also caused the pollution of the production environment and working conditions of workers, enterprises to remove these pollutants often need to spend a lot of money and human resources. The use of can reduce or even avoid the above-mentioned clean-up pollution of human and material resources, its no-wash can be directly welded characteristics, but also greatly improve the production efficiency of enterprises and product quality. The amount of IRMCO water-based bend grease can usually be reduced by 50%-80% compared to traditional lubricants, which can save more money for enterprises.
