five-point fiber laser cutting machine tips


 1) dual-focus laser cutting machine laser cutting head is fragile items on the long-term use, resulting in damage to the laser cutting head.

    2) every six months to check the fiber laser cutting machine rail straightness and machinery verticality, abnormal findings timely maintenance debugging. Did not do this, it is possible

Cutting out the effect is not how good, the error will increase, affecting the cutting quality. This is the most important and must be done.

    3) Once a week hydraulic manifold siphoning off the machine with a vacuum cleaner dust and dirt, all electrical cabinets should be closed tightly and dust.

    4) Always check the fiber laser cutting machine steel, ensures a certain tension. Otherwise, a problem in the operation, it is possible it will hurt people, but also result in serious

Deaths. Strip seemingly small things, the problem is still a little serious.

    5) fiber laser cutting machine each rail should be cleaned regularly to remove dust and other debris to ensure normal rack to regular cleaning, lubricating, lubrication without guarantee

Debris. Rails should always be cleaned and the oil, there is the motor should be cleaned frequently and lubricate the machine in the road will be better able to walk,

More accurate cut, teflon hose cut out of the product quality will be improved.

    Use these five points above technique is used in the actual situation summed up in bit by bit, with high maneuverability. Of course, the natural and skills with the actual situation

There are still some differences, when in use but also on the actual situation, everything from reality.

hydraulic fittings skills to use to explore


Tube hydroforming is divided into three basic types of industries: linear parts forming, with a boss or a twig parts forming, as well as parts forming the curve. Projections or twigs on the punch press with a certain degree of matching between the internal pressure back out to ensure that no bursting twig or wrinkled. Parts of the curve relative to the axis, the first CNC bender bent to the required shape, and then press-molded into a mold shown in Figure.
Tube hydroforming technology advantages and field of application is the development trend of total manufacturing lightweight product, process flexibility. Tube hydroforming hydraulic couplings technology is the production of hollow lightweight piece of advanced technologies for the manufacture of lightweight hollow class precision parts. For hollow tapered member, the traditional manufacturing process in general stamping for the first two and a half pieces and then welded into a whole. Tube hydroforming technology can be characterized by one member integrally formed along the axis of the hollow member section has changed.
Tube hydroforming technology advantages and stamping and welding process compared to the traditional, tube hydroforming technology has the following advantages: reduce weight, save material. Automotive sub-frame, radiator support and other typical products, hydroformed structural parts than stamping reduced. For a hollow shaft can be reduced, some parts can be reduced, reducing the number of parts and molds, reduce tooling costs. HV pieces often only require a mold, and most require multiple sets of stamping dies.
Car exhaust pipe in order to adapt the structure and function of the specific requirements of a catheter used in some cars very complex shape, not only in the axial sectional geometry different from a very different, but often the axis of three-dimensional curves. For this special shape of the profiled tube of the processing, if produced using conventional processing methods often requires many processes, and high cost, long life cycle. If using the hydroforming process, through rational design can often forming a mold cavity, as shown for the use of tube hydroforming process of production of the engine exhaust pipe. Compared with the casting, working life increased by 2 times, weight loss, shorten the development cycle.
Complex hollow shaft parts for tube bending or torsional loads bear the main shaft parts, you can use tube hydroforming process to produce hollow shaft transmission parts. Hollow structure not only can guarantee the power transmission capacity, and substantially reduce the overall weight, which is very important for the aerospace industry. Crank the engine crutches for Walker shows Germany with tube hydroforming manufacturing process Volcker engine crankshaft hollow crutches. Conclusion tube hydroforming technology in recent years has been widely used in industry, reducing the demand for quality and reduce costs but also promote the continuous development of the technology, the future prospects are very bright, very significant economic benefits, particularly in the automotive field will obtain a more lightweight wide range of applications.

45, rubber compensators range of applications?
Rubber compensators, also known as flexible rubber joints, shock absorber, pipe shock absorbers, shock absorbers throat, soft joints and other rubber compensators (also known as rubber expansion joints, rubber expansion joints, flexible rubber joints, shock absorber , pipe shock absorbers, shock absorbers throat, soft joints), generally made with rubber flanged ends smooth waveform compensation components with metal flange. Loose metal flange structure is often used. Waveform compensation quick couplings components for the rubber surface, the inner layer of strong fiber or steel amounted to (silk), etc. to strengthen mezzanine has been extended to both ends of the rubber flange which has a hard steel skeleton.

the structure and properties of metal hose


Corrugated metal pipe is a modern industrial pipeline a high quality flexible connecting tube. It mainly consists of metal bellows, metal mesh and various different forms of joint components. It is a spiral-shaped corrugated inner tube or annular corrugated thin-walled stainless steel bellows, bellows outer sleeve made of stainless steel wire mesh or stainless steel woven according to certain parameters. Hose connectors at both ends of piping or equipment in accordance with the user's joint form prepared.
        Bellows hose is made of hydraulic hose sleeve stainless steel seamless or longitudinally welded stainless steel thin walled tube through precision molded plastic deformation. Bellows hose contour determines the elasticity of softness and fatigue resistance, easy to absorb all kinds of sports deformation and cyclic loading, especially to meet the system larger displacement compensation.
        Corrugated metal hose has good flexibility, fatigue resistance, high temperature resistance, corrosion resistance, and many other excellent features, it is relative to other types of hose (rubber hose, plastic hose) lifetime is much higher, with the the development of modern industry, resistant to high temperature, high pressure, corrosion-resistant corrugated metal hose is increasingly widely used.

no encouraging signs of macroeconomic pressure hose rubber impact previous high is not easy


Nearly two weeks since the commodity markets up in good shape, showing easing of macroeconomic worries, the rubber also rebounded, compared with the beginning has risen nearly 4,000 points, it can be said rally gratifying, but I believe that there is no obvious signs of improvement in the macroeconomic , this rise is not sustainable existence.

First, determine the trend of any commodity to be from a macroeconomic view, and this is also the recent past the most influential factor on the rubber. Despite nearly two weeks, with the fifth installment of rescue loans for Greece, Italy austerity program through the European debt crisis, the impact of the market is no longer so large, the United States the number of initial claims for unemployment benefits hit a banjo fitting new low since mid-April, China hike bad landing and the first half of China's GDP remained 9.6% growth, easing investor nervousness, global commodity markets and the stock market has emerged as a steady upward trend, it seems that another wave of bull market is about to begin, but we do not think this is true, because there is no indication that any real improvement in the economy. The U.S. unemployment rate remained high at 9.2%, the employment situation is not optimistic, the source of high pressure hose of the financial crisis the real estate market and there is no improvement in performance, and the threat of global economic development has intensified inflation, India's inflation rate rose to 9.44 in June % rate hike is expected resurgence, if interest rate increase of 25 basis points, and that impact on the market may be small, but if it is 50 basis points, then the market is likely to be a shock like last caused a significant commodities fell; Chinese domestic June CPI has once again hit a new high of 6.4%, but we think this will not be far from the peak, pork substantial surge in oil prices has begun to limit the end, there was an anti seasonal vegetables rapid rise, steel, copper and other commodities also continued to remain high, if once the season ends supply of fruits and vegetables, you can imagine what kind of situation occurs, the controllability of inflation still only on paper, there is no data can give evidence, it is near the end of , investors expected the CPI for July will certainly start again, this will give the market impact. In addition, economic growth has also been the market's attention, the HSBC China purchasing managers index was 50.1 PMI6 month, close to line ups and downs, July data will be released in late July, when there should not be greatly improved, for the market is not a small vibration, so the above circumstances, I believe that the macro side there is a big uncertainty, which will affect the commodity market to weaken.

Rubber fundamentals have not hydraulic couplings recently there was a great change in the supply of the season, but the market did not feel like the status quo, to the volume of the market is still small, spot prices firm, but the contrast on the downstream rubber case, still There are many doubts on the inside. First, from the producing countries, production data, and does not appear because of bad weather caused by tapping the amount of the reduction, high pressure hose of natural rubber producing countries to increase production to different extents; Second, the downstream demand is still not open, U.S. June auto sales resumed growth, but it is annualized December to the lowest level, Germany is the one bright spot in car sales, an increase of 10%, Italy, Britain, France and other countries in June car sales is to maintain a downward trend, while Japan has shrunk 23 percent in June, China has ended two consecutive months of negative growth, there has been 1.40 percent year on year increase, but because the future is still 7-8 months off-season car sales, car production and marketing and will not appear an obvious upgrade, so combination of these situation, downstream demand for natural rubber has not been very good improvement; Third, from the domestic situation, the car sales in the first half of the year increased by 3.35% , tire production in the first half increased by 4%, natural rubber imports in the first half increased by 4.6%, while the last of the rubber stocks still remain at historically low levels, only 16,543 tons of inventory, and there is a big gap compared to previous years , compared to the above three cases, I believe that there should be hidden inventory of rubber, can not stand alone more optimistic of the inventory to determine the demand and supply of rubber.

In summary, the fundamentals of the rubber itself is no big change in circumstances, the macro factors will affect the trend is the main cause, while the macroeconomic uncertainty makes up more difficult commodity markets, high pressure hose rubber want continue upward impact early high point is a very difficult thing.

the main factors damage the sealing member


Sealing component damage is a major factor in the working fluid impurities. These impurities in the sealing member between the grinding, the valve leak. Therefore, the appropriate level of foreign has proposed hydraulic components should be used accordingly precision filter. They believe 5μM oil pump sealing element, if the filtering accuracy of a filter 3/μM life than the use of up to 10 times 10μM.
But the hydraulic valve bracket, the working environment is very bad. In the coal face, tubing length of hose nipples over 1000 meters, the joint socket up to more than 4000, no special dust tank facilities. Emulsion has a lot of floating impurities, Bottom of the column and the valve chamber, leaving more coal, grain and iron rock. Inlet valve and seat, as open and close more frequently, liquid flow rate is high, sealing will soon fail. Proven to reduce hydraulic system fluid contaminants, it is very difficult, it was once envisaged in the emulsion pump high-pressure filters, together with an increase in each bracket small inlet filter. But is blocked in the work quickly, to form stop.
On the other hand, as technology evolves. The performance of the valve and valve life put forward higher requirements. Currently, when equipped with a 120 mesh filter and the magnetic filter device conditions, with the valve being tested by the total emulsion flow rate and the valve opening and closing times, to measure the hydraulic valve life. But in fact the actual underground room type test results of the work with a big difference. Many countries are now in the form of experiments, an increase of china hydraulic hose anti-pollution requirements, some of them in the proper emulsion mixed with pulverized coal, some added mechanical impurities. To do this, you need to use the new, anti-pollution ability, suitable for underground working conditions manifold seal pair.
Hydraulic support various hydraulic valve life is low, foreign ways and means to solve the system is to improve the filtering accuracy and improving the quality of the emulsion, but with little success. This paper analyzes the stent valve sealing of the development process, discusses the sealing materials and sealing performance relationship. Pointed out the sealing technology is to improve the service life of hydraulic valve hydraulic support the key.

how to reduce fabric hose diameter round loss


Fabric hose because no molding vulcanized rubber hose inside diameter round loss is inevitable, may take the following measures to reduce the degree of loss round:

① rational design of inner plastic recipe, use less liquid softener, and the use of solid softener such as asphalt, resins and other solid Coumarone the tube well connected, easily deformed under pressure;

② inner plastic thickness cost permitting appropriate to increase (to be appropriate to reduce the cost of compensation with gum);

③ outer plastic extruded hose should be closely sulfide emissions and as soon as possible;

④ using direct steam curing, socketless fitting the inner diameter of 25mm hose the following vulcanization tray stacked layers not more than 3 layers stacked inside diameter of 32mm hose should not be more than two layers, inner diameter 38mm above the hose out of round seriously, best not to use this curing process, Boiled vulcanized be limited though, but should be avoided for the production of large diameter hose. Some factories had large diameter hose (32-76mm) conducted coreless direct steam partial pressure vulcanization molding experiments, the solution was bubbled delamination problems and the inner diameter round loss to obtain better results.

Fabric hose diameter round loss solution is: The ends can be uncapped autoclave, the tank in addition to a normal inlet pipes and exhaust pipes, the ends of the tank into the creation of flexible connections steam pipe and exhaust pipe, forming a good hose is placed on the platen vulcanizing car, there are loose ends platen steam through multi-plug pipe fittings, hose ends are inserted into each respective plug inside, fixed with clamps Well, then vulcanized vehicle selected into the tank, respectively, connected multi-plug Explorer and soft steam pipe attached securely closed autoclave, start with one end of the flexible hose connected to the steam pipe to enter the steam, and then give it away again autoclave steam, pressure inside the hose high pressure over 0.02 a O.03MPa tank under vulcanization. Hose inside the tank and the need for timely condensate discharge. After curing, while maintaining pressure exhaust steam and spray cold water in the tank to cool cans of soft connecting tube after each unload, pull vulcanized car relieved fixture, remove the hose cutting head checked.

cloth hose diameter round loss treatment


Fabric hose diameter round loss there are many approaches which can be used two uncapped autoclave, the tank in addition to a normal inlet pipes and exhaust pipes, but in the creation of two cans of soft convergence inlet pipe and the exhaust pipe, forming a good hose is placed on the platen vulcanizing car, there are loose platen two multi-plug through the steam pipe, hose two distinguished pierce each respective manifold block plug inside, fixed with clamps Well, then vulcanized vehicle selected into the tank, to identify the convergence of multi-plug Explorer and soft steam pipe attached securely closed autoclave, start with one end of the flexible hose to the steam pipe convergence enter the steam, and then give it away again autoclave steam, pressure inside the hose high pressure over 0.02 a tank O. 03MPa under vulcanization. Tank and hose need to live within the condensate discharge. hydraulic couplings Vulcanization end, stick pressure also exhaust and spray cold water in the tank to cool cans of soft convergence tube after each unload, pull vulcanized car unloading Lost fixture, pulled out the hose cutting head reversal. This approach works best!
