Roll Forming Machine is designed for the manufacture of corrugated roofing and wall material (trapezoidal sheet) with trapezoidal corrugations in height from 6 to 114 mm of rolled steel with lacquer coating and galvanized steel, thickness 0.5 … 0.1 mm. as well as a wide range of building profiles. Equipment for the production profile – accessories: rolls of double-seat Uncoiler R200M; guide, profiling Crates, electromechanical guillotine shears; receiving rack automatic control system (ACS) High-quality finished product provides a consistent method of profiling. Profiled lightweight and narrow profiles – this is a godsend for designers of quality and reliability for builders in the manufacture of prefabricated buildings, ventilated facades and roofs of modern practical. Production of corrugated board is constantly evolving, Our experts design and develop new types of profiles for different purposes, modernize and improve the roll forming equipment.
Decking (trapezoidal sheet) called the product of some form, made of steel. This product has excellent performance and enjoys considerable demand. It is not surprising, since these products are one of the best modern materials and finishes creation of various building designs. In addition, the decking is used for the construction of walls between the walls, floor to roof and walls, fencing and other facilities. This demonstrates the versatility this material. Production of corrugated board – galvanized kind – carried out on specific technologies, according to existing standards of GOST 24045-94, on a special roll forming equipments.
Decking can be wall (C), bearing (N) and combined (HC). The letters are marked and can help avoid mistakes when choosing. Mark sheeting is chosen based on where material will be used (for height fence, for example, or predestination constructed objects). For example, corrugated C8 is used for the construction of fences, walls different, country and other fronts. This variety is attractive and the fact that represented in a wide variety of colors. Or corrugated H57 Such material is often used for roofing of industrial buildings, as well as in construction work. N75 sheeting can be applied and how material for roofing and as a carrier material, presenting a corrugated profile, which is repeated on the width of the corrugated sheet.
To carry out major works fit saws with a cutting depth of 55 mm. Circular saws, cutting depth which is greater than 65 mm is classified as a class construction and purchase of such equipment will be justified only if you often have to cut very thick material. The more expensive models of circular saws are equipped with control electronics. Electronic Control Module allows you to maintain a constant speed regardless of load and produces a soft-start motor. This feature provides additional convenience at work, as well as prolongs the life of saw blade (in the case congestion or blockages, electronics, motor off).
Also, there are circular saws with adjustable speed blade. This feature extends the scope of circular saw and can select the optimum speed for each material. Now, virtually every major manufacturer such as such as Festool, or such as Protool, publishes a special frame for hand-held circular saws, with the help of a frame can easily be turned into a handsaw stationary (in this case, the saw is fixed up disk). In conclusion, let me give you some tips on working with circular saw. In carrying out precision work using fabrics with lots of teeth, this will ensure a smooth and clean drink.
Discs with a small number of teeth should be used if you want to a lot of work with high efficiency. If you plan to work with plastic, keep in mind that the speed of the disc should not exceed 3000 – 4000ob/min, in this case will be very useful function such as regulation speed. Cutting plastic, plasterboard, thin aluminum sections shall be made by special circular saw blades. Such drives usually have a special sharpening carbide plates and a large number of teeth. Working a circular saw, use a special bag to collect sawdust dust. For this purpose, so you can use a vacuum cleaner, although it somewhat limits the freedom of movement, but more efficiently remove dust. We hope this overview has helped you understand the technical characteristics of circular saws. But the choice is yours.
Mass production in its development follows the path of automation. Highly mechanized and automated mass production – a system of machinery, equipment, vehicles, ensuring strict consistent performance over time of all stages of manufacturing of products, from the receipt of initial preparations and ending the control (test) and finished product output at regular intervals. First there were designed automated production lines and hard-operated plants. With the advent of electronic software management tools created by computer numerical control (CNC) machining centers and transfer lines containing as a component of computer-controlled equipment. At the core of automated production lines are automated, which possess all the advantages of mass production, allows continuity production processes combine to automaticity of their performance. Automatic line (AL) – a system of automatic machines, placed in the course of the process and integrated system of management and automatic mechanisms and devices to meet the challenges of transportation, storage backlog, waste management, changes in orientation.
Automatic Lipno are used for automatically defined operations (stages) of the production process, depending on the type of raw material (billets), size, weight, and the technological complexity of manufactured products, so in the AL may include different numbers of Equipment: 5-10 for medium complexity products to 100-150 units. equipment for mass production of complex products. The complex includes the AL transport system for feeding blanks from a warehouse to stand, move outboard processing equipment from one booth to another to transport finished products from the stands on the main line or storage. Emit hard (synchronous) automatic production lines with characteristic of a rigid and unified communications mezhagregatnoy cycle of the machines and flexible (unsynchronized) AL mezhagregatnoy flexible coupling. In this case, each machine has its individual store drive mezhoperatsionpyh backlog. In Depending on the functional purpose of the AL in engineering may be procurement, machining, thermal, mechanical assembly, assembly, test, packaging, conservation and complex.
The problem of shortage of generating capacity has faced recently, Heat Supply Company Gatchina (Leningrad region). – City with a nearly 100-thousand people. "We were in a difficult situation, – said the chief engineer mue Thermal Network Gatchina Vladimir Sharabakin. – Urban Communications were established long ago and did not were calculated on the current load. To ensure full heat to all subscribers of the city center, it is necessary to change the main pipe, which will increase capacity heating pipes. At the same time, our calculations show that the heat, supplied to consumers, inefficiently used, especially in the offseason. When the premises became too hot, people open window and warm outside, and these losses significantly exceed our needs for additional energy.
If you replace the elevator units in homes for automated individual heat exchangers with a weather-dependent regulation, the load on urban heating system dramatically reduced. In addition, after installing the itp heating system in buildings is closed and the necessary operating pressure in its inner loop creates a pumping equipment within the of the substation. Thus, we can reduce the load on the pumps in boiler rooms, which are now "pumped" the entire city. And this is also a considerable savings. " A somewhat different problem has arisen in public utilities Zarechny Sverdlovsk region. The housing stock of this city has about 200 apartment buildings connected to district heating system. Despite the fact that in winter the temperature in these latitudes often falls below -30 C, in recent years zarechentsy suffer from systematic "melt down". "The temperature regime in the urban heating system is often unstable.
As a result of heating buildings comes superheated water. And the street is not always cold – explains the director of serviced urban housing management company llc "Deux" Sergei Skolobanov. – Therefore, in the houses warm. But residents do not have any means to regulate the air temperature. In result is that people pay for extra gigacalories, then how could spend that money, such as maintenance or improvement of their homes. " To remedy this situation, it was decided under the federal program Refurbished equip houses the heating system by means of thermal automatics. It is noteworthy that make it to the owners manual has recommended a management company. Last year, sixty homes Zarechny already established sites of regulation based on the equipment the company Danfoss, allowing to control the temperature of coolant entering the building in accordance with the changing weather conditions. Now the climate in their homes always comfortable. The logical conclusion was the translation of renovated homes on the metering of heat. "We not only solved the problem of" melt down ", but received a 20%-ing savings in payments for heating, – says Sergey Skolobanov. – Next year we plan to submit a new application to the Fund for Housing Reform and carry out reconstruction in 70 buildings. Most developed countries of Europe faced a shortage of energy for more than 30 years ago. And the stumbling block, as well as in Russia today, then become excessive power consumption of housing and communal services. However, experience in the last few decades has shown that this problem is solvable. Moreover, process of decision utilities can reach a new level of profitability. Similar transformations begin today in our country. There are already early successes. The main thing now – to make the most use experience of the nearest neighbors on the world map and the Russian regions. Press Service of the Danfoss
