Fold Purpose Machine
seam roof isroofing, which is formed from rolled metal sheet or by jointing edges of the metal seam called special seam.Using a standing seam welds provides absolute water resistance of the finished coating, because when there are no formation of through holes in the roofing materials.The limbs are classified according to the level o
a waterproof double standing seam is possible by hand with the help of special equipment or a modern way - Fold electromechanical seaming machine.The main purpose is to Fold machines mechanization of roofing work on the roof, which is made of steel.
Unlike conventional methods of roofing, using the machine turns Fold the roof in the form of rolls rather than individual sheets.The length of such a roll of steel - from the ridge to the eaves.Thus, the presence of such a machine will be able to enjoy all the benefits of modern construction technologies, for example, shorten the construction period every two or three, increase productivity, and reduce to a minimum the number of transverse joints.
With its small size, Folded rolled machines allow you to use them directly on construction sites.This construction equipment is capable of locking the seam to make a double and a triple, and achieve the ideal geometry, which is problematic for manual procedure rebate works.The panels are obtained directly from the laminated ribs that increase strength and improve the appearance of the roof.However, when a large slope of the roof does not get to use the machine.
With Fold forming machines roof paintings that have a standard rectangular, wedge-shaped and trapezoidal shape.This equipment is used when creating items such as roofs, air ducts, chimneys, sills, slopes, beacons of drainpipes, C-shaped rail, W- shaped profile, channels, angles, I-beams, elements of the snap connection, different fastening rebate (corner, lying, standing, snap rebate), ribs (trapezoid, a semicircle), fine curves of the roof.The most common type is considered to be joining the edges of the sheets lying falets single.
Fold tools help produce a different profile on the edges of the workpiece, or sheet of galvanized steel, including coated material.Fold the raw material for machine tools is a sheet or roll of sheet metal from low carbon steel, stainless steel and galvanized, plastic and lacquer coating (plastisol, Pur, polyester) and uncoated, aluminum, copper and zinc titanium.
Advantages Fold machines
The history Fold the equipment back to the distant sixties in Western countries, and today these machines are extremely popular.In modern equipment the domestic market is mainly represented by foreign companies and are of high quality, high productivity and ease of use.Among the shortcomings highlighted unless a huge price Fold machines by Russian standards and greater headroom.
Fold equipment has many advantages and benefits over other similar plants:
- adaptation to the conditions of Russian construction sites;
- damage the coating material;
- highest standard panel-paintings by fine design and optimization of the configuration of profiling rollers;
- achievement output linearity panels;
- the manual speed changeover to the desired width of the workpiece;
- the opportunity to complete a manual cross-cut knife;
- possibility of additional installation of rollers that are used to hire ribs arched and paintings;
- providing quality rolled metal with polymeric coating.
design Fold mechanism
Fold rolling machine is a mechanism which is intended for profiling the edge of a sheet or coil metal for further creation of rebate.Simply put, the device is one of the arches of steel edges for a certain configuration for the product of their compounds.The use of this equipment contributes to obtaining blanks, reliability and quality that far exceeds the quality of counterparts, which are obtained by manual processing.
himself Fold roofing forming machine consists of a device, the frame and drive.Stand - a welded steel structure, on which are placed six pairs of shafts that serve as the forming unit.Serves forming device to pull the metal strip along the machine and forming ribs and the constituent elements of the double rebate on its edges for double locking connection.When you change the width of the metal strips can reconfigure the device to the new size.
electric drive consists of an electric motor, chain drive and worm gear.In addition Fold rolling machine can be set roller unwinding device that is designed for the installation, unwinding and feeding of rolled metal, which has a weight of up to 1 ton.In addition, the machine can be equipped with means for constraining the compound sheets in a single roofing sheet, profiled on that machine.
mobile unit of the machine consists of two movable rods that are rigidly connected to each other the pressing gon.The horizontal shelf of the polygon is designed as a wedge, which is located at a longitudinal bracket for crimp in the longitudinal recess polygon edge roofing sheet.Guides for the rods are the staples and walkways at the ends of the horizontal shelves.Mobile unit Fold machine held by the springs in the upper position in which it is possible to insert a sheet into the machine and remove it after the process of bending the edge.
profiling device located on a steel tubular frame.The rollers are made of high-quality special steel with special finishing, which guarantees the effectiveness of the protection from the effects of corrosion.Televisions are two types of crimping device - automatic and manual.Fold the machine is equipped with four wheels grand piano type, two of which have brakes to significantly facilitate transportation.
Fold This design allows the machine changeover to work with metal, which has a different thickness, and perform correction of bend edges using sealing tape at the device seam roof.Possible to consider additional equipment for installation of the roof at a higher speed and simplify the procedure.This is facilitated by the installation control system, circular saw blades and cross portable circular knife.
characterizing the operation of the machine Fold specifications such as the speed profiling and allows the thickness of the sheet metal at the entrance.Various modifications of machines capable of producing several types of rebate, so it is advisable to pre-book the required set of rollers rolling.
principle of operation of the machine Fold
Before making Fold rolling machine, should know how it works.The principle of operation is based on machine Fold roll technology, which provides the possibility of manufacturing roofing pictures of the entire length of the slope and avoid unnecessary horizontal connections.Iron Roll roofing sheet is much cheaper, it is convenient to raise the roof and direct it to make a picture.A roll of metal strip is placed on the unwinding device.
After clicking the "Start" button that is located on the keypad, turn on the electric motor, which, via a chain drive gear and transmits the rotation of the shafts forming unit.The end of the metal strip is fed along the guides on the machine first pair of forming rollers.Rollers captured metal strip and extends across the entire surface of the forming unit.When you reach a certain length of the molded sheet Fold the machine is switched off by pressing the "Stop".To eject the molded sheets back in the designs available reverse.
After that installers need only connect the two parts.In addition to these roofing, recumbent folds, made with faltsegibov used for the manufacture of pressurized air lines or drain pipes.Transporting the machine is permitted in any position that does not allow mechanical breakdowns and controls design.Periodically, it is desirable to carry out preventive settings and lubricate the working parts (chain, screw the pressure roller, chain tensioner, guide pressure roller, gears).
use Fold the machine in the home
Since the price is high enough Fold machines, home made to collect product yourself.Homemade Fold rolling machine is mounted on a workbench in a way that placed in the same plane with the working surface of the machine horizontal leg gon.For limb edges lying rebate standard sheet must be put on the machine so that the stops was the butt of his shotgun narrow side.As a result of pressure on the pedal on the sheet there is a small depression.With braces need to turn is bent elbow, is folded at a predetermined angle edge of the sheet.
After bending the edges to fold, release the pedal: the mobile device at the same time strives upward by springs.Elbow is bent at the same time assigned to its original position.The sheet comes off when lifting the mobile device with the clamping gon.The sheet is then rotated 180 degrees and folded in the same way on the other side edge of the sheet for the fold.From single manufactured in a similar way to collect paintings made double.Assembling is performed manually or by using machine faltsezakatochnogo.
Small Hand Fold rolling machine is used for bending the edges of the short side of the sheet.The frame that is made of parts, reinforced corner presser plate that is welded underneath.Clamping area is raised and lowered by the pedal.Sheet steel roofing is laid on the table of the machine and the short side is put under pressure with the release of the edge area of the sheet outside the width of the bending fold pin-up stops, which are available on a bending bar.
pressing the pedal, roofer grips the edge area of the sheet, and then rotating the bending bar, it makes for limb edges lying seam.Harvested this way the sheets are connected in pairs in the pictures on the drive roller machine.In the center of the machine there are two rollers one over the other, that planted on two shafts.The rollers are set in motion by an electric motor and a belt drive gear.Roofer interconnected links the two curved edges of the sheet and pushes between the rollers, sealing recumbent fold.Then fold the edge of standing seam.
Corner rebate used in the performance of such elements of the roof, as the umbrellas and hoods for chimneys, as well as the creation of household equipment.Begin to connect two pieces of simple angular seam contour in them 90 degrees edges, and placed one of them on the plane of the sheet.Then, the machine has a sheet with upwardly bent edge, which is introduced into the gap that is formed after the edge of the flap of the other sheet.The resulting comb after compaction dumped on the surface of the first sheet.
to connect the combined angular seam two pieces of sheet edge that is shifted from the machine, bent at 30 °, and in it doing a breakdown.The sheet is then inverted and the resulting breakdown blamed on the surface and the folded edge, forming a double-lying limb.Leaf with a double limb then install the machine and the factory in the slot of the second bending edge of another sheet that pre-bent.Vertical edge conclude blamed on limb of the first sheet to the plane of the second sheet and sealed on a metal support on both sides.The width of the edge in the sheets, which are connected to the corner folds, depends on the thickness of the sheets.
sequence of operations to create a double corner seam will analyze the example of the insertion in a rectangular box of the bottom.Pricherchivayut to the bottom edge of the box the size of the formation of folds and cut corners.The dotted lines after all edges are bent at the bottom in the same direction, on the edges of the outer sides make narrow folds.Carton corners notched, and thereto is inserted bottom.Dump the bottom flaps on the sides of the box, while using a mallet and a metal fence.Next, the box is placed on a workbench, consistently align all edges single seam.Edges Finally edges at the side walls of the box and then compacted.
When manufacturing different roofing elements and inventory owners have to connect the parts not only through the corner seams straight, but also curved folds that connect the cut made at an angle and round pipes.The design of the curved seam is the same as direct.When the curved junction rebated additional operation is flanging that is to extend the edges are folded due to thinning of its thickness.
