PIP crack robot manipulator problem

In Hebei, there is an oil tank factory, which is a military enterprise. One day in 2014, the oil tank plant received a very important task for the production of hydraulic cylinders for the "arm" of the seabed robot.

Hydraulic cylinder is a common equipment, which is composed of cylinder sleeve and piston rod. Through the hydraulic principle, the piston rod will move reciprocally, thus driving the mechanical equipment to make some actions such as tightening, loosening and pushing.

In our daily life, often can see excavators, bulldozers and loaders working in various sites, these machines can do these jobs are to be completed by the hydraulic cylinder, so that the image that the piston of the hydraulic cylinder, is the mechanical arm "".

Based on the working task of the piston rod, the wear resistance and corrosion resistance are two of the most important properties. In order to achieve the purpose of corrosion resistance, the piston rod usually has to be plated with metal chromium on its surface through electroplating. Because chromium is a relatively wear-resistant and corrosion-resistant metal, it can ensure that the "arm" of these machines can work for a long time.

However, in the working environment of the seabed robot, the chromium piston rod can not meet the requirements. Because of the serious corrosion of the sea water, the arm of the submarine robot, if used, will be rusted for a very short time if the chromium piston rod is used, and it can not work properly.

In order to make the arm of the seabed robot work properly, the oil tank factory uses stainless steel to make the piston rod. The arm of the seabed robot is very strong, 3 meters long, with a weight of 1.7 tons. Stainless steel, compared with ordinary steel, is not only expensive, but also difficult to process.

Who knows the stainless steel piston rod, also can not stand the strong corrosion of the sea water, half a year will be replaced.

In order to find the submarine robot piston rod more appropriate, the military enterprises, through various channels to find Hunan Hongyu wear-resistant materials Limited by Share Ltd (referred to as the Shenzhen Stock Exchange listed companies, Hongyu new materials SZ.300345, Professor Luo Defu chief engineer). At that time, Professor Luo Defu was studying and developing PIP technology. The Chinese name is controlled ion infiltration technology. It is a new metal surface modification technology.

PIP uses various process methods to infiltrate non-metallic elements and trace metals into the surface of metal substrates, forming a multi-layer compound layer which is composed of metal oxides and non-metal elements, which has very strong wear and corrosion resistance. Not only that, PIP technology can also control the thickness of the layer to meet the different wear resistance and corrosion demand.

Although professor Luo Defu's PIP technology was still in the pilot stage at that time, the military tank enterprise with an eye ahead was willing to try it.

The results showed that Professor Luo Defu failed to live up to the expectations of this military enterprise. Today, a year and a half later, the arm of the submarine robot is still not rusty, and it is still working normally.

Super wear resistance, PIP technology in the military enterprises begin to display talents.

Because of the excellent performance of PIP products, the application field of PIP technology is further widened. In the export of weapons on the gun, in the petroleum enterprise sucker rod, piston rod of the world's largest agricultural machinery agricultural machinery enterprises -- the United States of John Deal, all shining figure of PIP products.

In order to speed up the promotion of PIP technology industry, December 2015, Professor Luo Hongyu new materials with Telford and other investors, initiated the establishment of intelligent Hongyu company, opened a prelude to promote the industrialization of the PIP technology.
