Classified machines for printing on such grounds: the system paint (open or closed), the drive, the type of tampon, automation. Machines are also rotating and plokopechatnye. Types of actuators can be divided into hydraulic electromechanical, pneumatic (electro). Electromechanical machines are quite expensive for the price. If you are using software control the machine, its equipped with an electromechanical drive. Printable products using large format equipment with hydraulic drive, so it is now possible to create high pressure. But the pneumatic machine is well managed, easy to use, easy to machine parts available. These machines are stable at the pressure of the product.
In the tampon printing process removes paint from a printed form. Then move the product and gives it color. There are two systems of the type of movement pad. Credit: Lever Brothers-2011. The first system – A movement for a tampon printing form and the perception of the image they paint. Next, the piston motion picture is transferred to the product. The advantages of this system in usability work. A disadvantage is that Quick Print tampons can be excited.
The second system operates as follows: swab down on the form using a piston takes the paint and pulls away. Plus, such a system the ability to print on large speeds and a tampon is not swinging. But it is not easy adjustment and improved the work. On hand looms have to apply paint by hand, using a special brush. Squeegee fill the printing and immediately remove. If the edges of the paint remains, its clean with swab dipped in solvent. Before you start printing products in large quantities to make a test print. Need to adjust the course of the tampon, the height the stage, the correct move a table in the horizontal plane. Tampon use of monochrome, multicolor and two cars.
The first transformer with open magnetic circuit proposed in 1876, PN Apples, which used them to power electric "candles". In 1885, Hungarian scientists M. Dery, O. Bluth, K. Tsipernovsky developed a single-phase industrial transformer with a closed magnetic circuit. Three-phase transformers have appeared in the 1889-1891 years. (MO Dolivo-Dobrovolsky, Tesla).
Transformers are widely used in various fields of electrical engineering, radio engineering, electronics, units of measurement, automatic control and regulation. In terms of design and implementation of a high-voltage equipment can be divided into force, welding, measuring, and special. The greatest application in the national economy have power transformers, which are an essential element of industrial electrical networks. Generators in power plants generate electricity at a voltage not more than 24 kV, since at higher voltages have difficulty creating enough insulation in electric machines. Electric power transmission over long distances at such relatively low voltages economically unprofitable because of high losses in the line.
Indeed, at low voltages, U is the same power (P = UI cos ) is obtained at higher current, I, therefore, increases the power losses in the wires PI2, ie necessary to increase cross-section. Therefore, the power plants installed power transformers, which increase the voltage to 110, 220, 500, 750 and 1,150 kW. Consumers with voltage transformers is reduced in several stages: at district substations and 35 (10) kV substation facilities to 10 (6) kV, and finally, at the substations of shops and residential areas – up to 380/220 V. As the number of phases transformers are divided into single-phase and three phase. Each phase of the transformer has primary winding (her energy is fed from the source) and the secondary (with her energy will reach the consumer). Secondary windings of this high-voltage equipment can have several – in this case, the transformers mnogoobmotochnymi called. Thus, single-phase transformers have at least two windings, three-phase – six.
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 total rate of display is 250 k / sec. Through hardware processing, and the Linux operating system in the early remote viewing via the network or display speed or write speed is not reduced. By separating the processes of observation and recording, users at remote the workplace can reduce the quality of “live” video without affecting the quality of the recording. This feature is extremely important for connections using low-speed networks. The second signal is fed to the first video capture card, and then to the board compression, where the hardware compression. Compressed data does not load the system resources and is easily stored on your hard drive.
The total recording speed of 400 k / s on all cameras, with resolution of the recorded video or 720h288, or 720×576. If the simultaneous recording of 32 cameras, the average speed record in each chamber is 12 k / sec. In practice, in most cases, a speed of 5 k / s allows you to make some good shots, which in later identification of the suspect will happen. The compression algorithm used by the registrars Hitechnology based on h.264-technology and has a high level of encryption. With high quality and the inability to edit frame Hitechnology company received the European certificate, and is currently recording made with registrars Hitechnology accepted as evidence in the European courts. The DVR supports 4 internal hard disks 2000Gb everyone – that is, the total internal volume of 8Tb, which, with an average activity in the frame enough to record 32 cameras for a month. Thanks to the original video at the same time the division reached High speed display and high-quality recording, the DVR Hitechnology is effectively fulfilling both tasks surveillance systems.
Background. Lathes are machining the internal and external surfaces of the workpieces such as bodies of revolution. By the way, turning operations occupy the largest share of the overall complex machining. On CNC lathes vypolyayut following operations: turning, drilling, tapping chisels, etc. Classify the machines can be on the following criteria: location 1.Po spindle axis (horizontal and vertical machines); 2.Po number of instruments used in this work (one-and mnogoinstrumentalnye machines); 3.Po method of attachment tool (on the caliper, a turret, in-store instruments); 4.Po view of works (post, chuck, chuck-center, carousel, rod machines); 5.Po degree of automation (semi-automatic and automatic). Pivot machines used for machining parts such as shafts with straight and curved contours. On these machines can cut thread cutter on the program.
Cartridge machines are designed for drilling, deployment, tapping in the axial holes of parts, cog wheels, possibly a chisel cutting the inner and outer thread of the program. Chuck-center machines combine the capabilities of turning pivot cartridge and CNC machines and are used for exterior and internal processing of various parts such as bodies of revolution. Rotary machines are used for machining of complex cases. CNC lathes are fitted with turret or tool magazine. Turrets can be four, six, and dvenadtsatipozitsionnye, and at each position can be installed on two tools for external and internal machining of the workpiece. The axis of rotation of the head can be positioned in different positions relative to the spindle axis.
Fixing turret is done by using special socket joints, which provide high accuracy and rigidity of fixation of the head. In the groove turrets installed replacement power tools, which set out the size of the machine on special devices, which significantly increases productivity and accuracy. Typically, for turning processing is used no more than 7-8 instruments. Enhancing the technological capabilities lathes can be accomplished by obliterating the distinction between turning and milling machines, adding various additional operations such as milling (ie, programmed spindle rotation).
Our consciousness is arranged so that when he saw the structure of the "red" brick, it automatically assigns it the epithet "reliable", "beautiful", "durable." And it is true. The emergence of manufacturing technology bricks made of clay, its mass production, has allowed mankind to make strides in the construction industry. What is a ceramic brick? Brick is defined as explanatory dictionary lump of clay, fired in furnace. Then, for example, silica, or "white" brick and brick that can not be named because he is made of a special mixture in an autoclave, without being fired. Thanks to its "convenient" size 250mm x 120mm, mason convenient to take brick with one hand. Industry produces ceramic bricks and other dimensions: the "double – 250mm x 120mm x 138mm, Bastard – 88mm and the "single – 65mm thick. Standard defines a "double" as a brick – "ceramic stone." Masons often advantageous to use when building a house ceramic stones, due to lower consumption of the solution and the time for the erection of walls. It advantageous to the customer and, as a "double" brick, being more than double the usual volume, is only half the more expensive "single", while the cost of the works themselves do not increase.
Ceramic brick is divided into species, defined area of application: 1. Private (building) brick. They are laid internal or external rows of masonry, which are then applied a layer of plaster. 2. The front (facing) brick.
This brick is different from the ordinary with two flat, smooth surfaces, and has a typical uniform color. Many voids in the facing brick walls reduce heat conduction from a folded, making them more "warm". 3. Textured and shaped bricks – are also facing. Of those laid out complex forms: columns, arches, etc. 4. Occupies a special place chimney brick. Technology and materials used in its manufacture, making it the most expensive of all types of ceramic bricks. Referred to as ceramic bricks – "red." It is a consequence of the fact that in its manufacture are often used so-called "krasnozhguschiesya" clay. Roasting, rarely occurring "belozhguschihsya 'clay bricks produces yellow, apricot and even white color. The presence of voids in the "body" of the personal and ordinary brick divides it into solid brick and hollow brick. The greater the percentage of voids, the 'warmer' brick. Ceramic stones are made only hollow. Modern technology make it possible to produce porous brick (its structure resembles a sponge). This brick is very "warm" and, furthermore, has excellent sound insulation. Manufacturers today offer a wide choice of range of clay bricks, different types, sizes, shapes, colors and properties. When choosing a brick for the construction of ignorant people is best to consult a specialist. It helps to calculate the number of necessary materials, as ceramic brick product is not cheap and as a result of incorrect calculations and choice in the brick walls can "fly into a lot of money."
