for bending metal profiles can be used a variety of bending machines, but profilegib is the most convenient of them by their own merits.But costly Profile bending machine is not available for all people.However, you can build it with his own hands to meet your individual needs.Before you begin, you must understand why you need a homemade profilegib.Let's try to understand the existing classification profilegibov, their design and operation, the main stages of construction and the process of bending.

profilegib today is widely used in the manufacture of steel, copper, aluminum and PVC pipes and metal profiles, as well as for laying gas and water supply when installing cable
When the metal should be bent at a desired angle, the most commonly used home-made hand-profilegib.This special equipment allows to bend the metal profile by cold rolling without heating the parts.Also roll-forming machines allow to obtain products and alternating single curvature unbalanced and balanced circuits.
profilegibov main advantage is to perform a bend just one rental.You can process metal profiles in the horizontal and vertical planes.Thanks to the machine will make a circle of metal blanks.There is the possibility of performing a spiral pipe or profile.Machines allow you to open and closed loops, as well as those that have a smooth transition.
profilegiby today are very popular in many areas of construction, energy, marine, automotive, sports, petrochemical, furniture, electrical industry.The process is carried out by bending radius and consists of two main movements: the blank is rolled between the rollers while urging the upper roller and side rollers.
Bending machine is a easily transportable machine with mechanical, electrical or hydraulic, compact size and relatively low weight, which is designed for bending metal by cold rolling.To reach the optimal parameters the curvature often use special nozzles that help to process a variety of products.
There are four types of roller systems profilegibov.Installation of the upper movable roller is the easiest kind used in terms of the mechanics of his work since moving only the upper roller.Implementation of such a mechanism is different: the upper hand-clip - with the help of gear, hydraulic - hydraulic system with control of the upper roller.This arrangement makes it possible to calculate the rollers possible bending radius for products with small errors on upruzhneniya material or slight gradient in the deformation of the profile.These drawings profilegiba are the most common at the moment.
models with the left movable roller is suitable for curling spirals and allow you to perform the same functions as the previous profilegiby with honors only in the mechanics of the drive side of the roller.Models equipped with CNC controlled gradient so flexible and bent parts from the original drawing, or have management functions with pre-bending.
Profilegiby with movable lower side rollers are used primarily for bending large profiles, because the bending force is distributed evenly on both the lower shaft and the drive is fully hydraulic.There is every tree own controller position to preserve the possibility of flexible spiral.This design is most consumed because the rollers move along the segment of a circle.
Models that are moving all rolls have the complex construction that includes a machine all the previous advantages.These made their own hands profilegiby able to do the work being done individually previous arrangements.
The principle of profilegiba
profilegiba main difference from other tube bending machine lies in the fact that profilegib metal deformed by rolling rather than by bending.All profilegibov working principle similar.Profilegib rigidly mounted and fixed through special holes made in the frame, with anchor bolts.Profilegib before starting work must be grounded to check the integrity of the electrical and mechanical connections.
Before initial start-up rollers are cleaned of preservative grease with a dry cloth and check that the supply voltage characteristics profilegiba.Next profilegib driven around idle for 30 minutes.If there are deviations from normal operation, the machine is stopped and the fault is corrected.
blanks are cleaned from oil and check the hardness of material that needs to be the entire length of the same workpiece.Then adjust the rollers to handle the bend parts in the following sequence: first, supporting nuts and pressure rollers spun key, then the rollers mounted on shafts with key and fix with the nuts, then use the handle to lift the upper position the pressure roller.
parison is clamped between the rollers, then it occurs between the rollers rolling under high pressure, as shown in profilegibe video of his hands, whereby the bending occurs profile.The radius of curvature is set by raising and lowering the upper shaft.In manual profilegibe mechanism actuated by a lever that rotates the operator.Electric profilegib works thanks to the electric motor.
external classical profilegib resembles the letter "T".There are several types of devices that are different technical characteristics, quality and price.
Usually electrically profilegiby produced in large massive machines are therefore suitable only for use in stationary conditions.However, at the same time such profilegiby used for bending the profile that has a small cross section, so often used in small factories and home workshops.This equipment is characterized by increased levels of accuracy and perfectly retains its strength in the field of bending pipes.
deflection angle can be marked in different ways.When using the mechanical method applied special marks, a little reminiscent of the clock.But the more modern method is digital.Through this approach, the angle of deflection is created by the installation of electronic and controlled on the screen.However, this tool has high cost and great weight.
Profilegib with the hydraulic system is used on an industrial scale.These profilegiby used by true professionals at the device drains or water and is ideal for stationary conditions.This type profilegibov characterized in that only works on a network.The main advantage is the high speed, preservation of mobility, ease of use, lack of stress on the user.
profilegib This is the cheapest and most affordable, you can even carry.This equipment can be used in the home, garage or service station, since the drawings are not intended to hand profilegibov training machine.The disadvantages are: a large load on the user, the inconvenience of a few bends in the same pipe work only with thin tubes, prolonged bending for a few minutes, virtually control the radius of deflection.
But even with these drawbacks, hand profilegib is the most viable option for the home.If the installation of heating or running water, you need to bend a few rods or tubes, to acquire an expensive tool simply makes no sense.Hand-held equipment can perfectly cope with this task.
kinds of hand profilegibov
For home use perfect manual profilegib.If you do not plan to use profilegib for a long time, it is better to buy an inexpensive option, or to make a manual model.You need to know that there are several options made with their own hands profilegibov hand, each in its own way is different from each other.
first option is the most common.On the tube, which is subjected to bending, moving the special rollers that affect her his strength and bend it.This device bends the tube around a fixed frame.For pipes made of nerzhaveek this option is ideal.Almost all of its models allow us to bend the pipe to 180 degrees.
second option - is profilegiby that squeeze the tube with a special device in the place of bending.They move toward the rim is bent material.This option eliminates the possibility of the appearance of wrinkles by moving the frame and squeezes flexible material.It is also equipped with a ratchet, which can significantly increase the force of arms.This profilegib convenient to use even with one hand.
If you need to bend the pipe is very thick, it can not do without a manual hydraulic profilegiba - the most powerful versions of the manual.It is equipped with special hydraulic pistons that create pressure on the details in a few tens of tons.Hydraulic tools can bend parts 90 or 180 degrees.
Manufacturing profilegiba own hands
If you want to apply for profilegib huge amount of work, it is better to buy a special version, which is endowed with a lot of features and is a much stronger hand.But for simple pipe bending ideal hand equipment made with their own hands.
design will depend on the diameter of the pipe.There may be several options.If the tube diameter is not more than 20 millimeters, the pipe can be bent by using a concrete slab with holes in which to place the steel pins.Thus, the tube passes between the pins and bent to the desired angle and direction.If the thickness of the pipe is greater than 25 millimeters must be developed drawing profilegiba own hands more difficult.
To do so, attach two clips on the ground.Rollers should have a circular cross-section of the side face.Wherein the radius of the side face should have the same diameter as the pipe, which is subjected to bending.The tube must be inserted between the clips and secure the end.Thereafter, the free end is attached to a winch, whereupon it is driven.When the pipe reaches the desired bend, you can stop the winch.
Next you will need mortar, which is made of sand in the ratio 1 to 4 (meaning that one part of cement used in four parts sand).Also need thick pieces of pipe and a diameter of about 70-100 mm.You can use the channels, which are ideal for this purpose.
on earth is ground cement, which are inserted into pruning these pipes.First, they are inserted vertically into rubble.The distance between these elements must be equal to 40-50 millimeters.After this area is filled with cement, but the pipes should maintain an upright position 90 degrees.On dry sites will take a couple of days.
To avoid cracking, buckling or bulging, before heating pipe is recommended to fill quartz river sand.This technology is used by many builders.The advantage of quartz sand is that it does not contain burnable organic fractions.To determine the sand, you can carry out the experiment.To begin with dry sand, using a temperature of 150-300 degrees.Then sift it through a fine strainer with a cell of 1.5 to 1.5 to separate the particles which, when heated, can burn on to the tube wall.Ideal sand should not stick to the walls.
Before filling sand tube, plug one end of a wooden tube, the length of which shall be equal to 1.5-2 times the pipe diameter.Taper ratio of 1:10 to 1:25.When all the preparatory work will be finished, you need to pour a small amount of sand in the scrap pipe and heat it to a dark cherry color.After cooling the tube, you can fall asleep in her sand and carefully inspect the walls.
If the length of the pipe is not more than 2 meters, you can fill it yourself.Place the tube upright and pour the sand in small portions.Here is the rule: after each addition is necessary to lift the tube and gently obstukivat a hammer.Continue to do this job for as long as the voids are completely gone.This is to notify the empty sound of blows of a hammer.Remember that the sand should not reach the upper edge of the tube about the diameter.
beyond what is necessary to hammer the plug in which several pre-drilled openings for exit, resulting gases.The plug should be possible to speak of the pipe so that you can easily remove it after completion of work.With chalk mark must be applied around the pipe in place most of the bending radius of which must be at least three or four pipe diameters, as in the photo profilegiba hands.
If the pipe is bent at an angle of 90 degrees, the interval should be warm six pipe diameters.If the pipe is bent at an angle of 60 degrees, the interval can be shortened warm-up to four pipe diameters, and if the planned bending angle of 45 degrees, the tube must be warmed by only three diameters.
heating should be discontinued as soon as a tube fly away all dross.It is a sign of complete heating pipe.If the surface of the tube will spark means that it simply perezhzhena.The tube is necessary to bend one warm.If these attempts will be somewhat, they may impair the structure of the metal.
Remember that a device for the hot pipe bends should be a template, without which it is difficult to obtain the desired configuration.Also, do not forget about safety rules: while working do not stand in front of the battered wooden plug into the pipe.When the hot pipe bending come to an end, it is necessary to pull the cork out of it and shake the sand.It thus becomes a manual profilegib.
profilegib you can buy in special shops or companies, and can learn how to make profilegib, and compile it yourself.To produce such an option can be yourself, you do not need any construction skills.If you use the above tips on making profilegiba difficulties during bending will disappear completely, and the need to buy an expensive tool.
