Reliable homemade profilebib

Homemade profilebib - is it real? Consider more. Often in everyday life there is a need to bend the reinforcement or profile pipe. To carry out this action will help a special machine that you can make your own hands from the usual devices. There is no doubt about the reliability and safety of such equipment, and its price will be 10 times lower than the market one. Self-made profilegib is distinguished by its unique design and bending features. About the principles of its work can be found below. This machine is used for the manufacture of pipes from copper, steel, aluminum, plastic, and also as an attribute intended for laying gas, water, cables. With the help of such equipment you can bend beams, pipes, angles, channel bars, metal rods. Moreover, this device helps to deform the material by 360 degrees.

Self-made profilegib carries out such activities by cold rolling, early heating of the products is not required here. With their help, you can make objects whose contour has a proportionate and disproportionate characteristics. The positive quality of this device is the implementation of the bending in one rolled, the execution of the contours of the open and closed types, spiral materials from pipes.

Bending equipment is a transportable mechanism with different types of drives. They can be electrical, mechanical, hydraulic. Distinctive features are the small weight of the product and the bending of the metal using cold rolled products. Nozzles allow processing of any surfaces.

Profilegib can be equipped with different roller systems. So, models with the top location of this part are simpler. Their device allows you to determine the radius of the bent object with minor errors associated with their level of elasticity. Such drawings are used most often.

Variants with a left roller position help to bend the helix and perform other functions that were mentioned earlier. The product is equipped with CNC, bending gradient is monitored, external indicators of the part change depending on the drawing.

Profilegibs, equipped with wheels on the side, are used to bend articles of considerable size using a hydraulic drive. Frequent use of such devices is associated with the circular movement of these wheels.

The varieties in which all the rollers are driven are distinguished by a complicated construction, but they have a number of positive characteristics. They can do all the work that only individual models can do.

The peculiarity of the work profilebiba

Specifications Profilegiba

Specifications profilegiba.

This machine deforms the metal by rolling, but not bending. Regardless of their varieties, such equipment is based on similar principles of operation. Before starting the mechanism, grounding measures are taken, after which the accuracy of the work of its electricians and mechanics is checked.

Grease is removed from the rollers, then the voltage is monitored. After that, within half an hour, the profile-bend is turned on, its working capacity is checked by the idling of the mechanism. Emerging faults should be eliminated.

The surface of the workpiece must be equally hard throughout the base. The wheels are prepared in this way: the fixing nuts of the supports and the pressure rollers are turned away with a key, then the coils are placed on shafts with keys and fixed with nuts, then the pressure elements are raised with a handle.

The workpiece is fixed in the space between the shafts, rolling is carried out at high pressures, this is how the profile bends. By raising and lowering the upper shaft, the radius of curvature is changed.

Machine manufacturing process

The choice of bending forms for steel pipe

Choice of a bending form for a steel pipe.

Independent production of such equipment does not require particularly accurate results. For consumer service is quite suitable manual machine. His device is determined by the diametrical values ​​of the pipe. The cross section of the used blanks is equal to 20 mm or less. Such a product is deformed by means of a concrete slab with grooves, steel pins are fixed in it in advance. The pipe passes between them, it is given a given shape and angular parameters.

The wheels are fixed on the surface. They are characterized by a rounded section of the side parts. This face must be the same in diameter with the pipe undergoing deformations. The workpiece is installed between the rollers, its end is fixed. Then the free end is connected to the winch. She starts moving. At that moment, as soon as the pipe will take the desired size and configuration, you should terminate the winch.

Then you need to mix the cement mortar in proportions 1: 4, most of these components is a sandy substrate. Here you can not do without pieces of pipes whose diameter is 70-100 mm. Channels are the best for such purposes.

A cement platform is being built directly on the soil, the cut parts of the blanks are fixed in it.

The allowable distance between them will be 40-50 mm, they are fixed vertically in the rubble. Then the place is filled with cement, the right angle of location is preserved, after 2 days the surface will dry out.

On the eve of the procedure, the pipe is pre-filled with quartz sand, which will eliminate the appearance of cracks, crumpled parts, and bulging. According to this method a large number of professionals work.

Before filling the pipe with a sand mixture, it is closed with a wood stopper, its length corresponds to 1.5-2 times the diameter of the workpiece. Then the small substrate is poured into the workpiece and heated to burgundy color. As soon as the pipe cools down, you can fill it with sand to the maximum limits, then carefully examine the walls. To do this, it is placed vertically, filling the sand with small pieces. As soon as the next dose is dispensed, the pipe is raised and tapped with a hammer. So you can achieve the highest rate of shrinkage of the sand layer. To understand that there are no voids in the plane, a thud from the hammer blows will help. It is not recommended to pour this substrate over the top.

After the sand has fallen asleep, a cork is inserted into the groove, at its base there should be small holes for removing gases. To facilitate the process of its removal as the work is completed, the cork is fastened as far as possible, protruding from the pipe. So it will be easier to pull out at the end of the work.

Completion and debriefing

As soon as the pipe warms up completely - this can be understood by flying scale from it, these actions cease. The appearance of sparks on the surface of the product indicates that it has been over-exposed. The pipe must sag in one warm-up procedure. Repeatedly holding such events may not have the best effect on the metal.

To pipe acquired the desired shape, it is necessary to prepare a template. During work, it is important to observe the rules of personal safety: you should not be at the product, which is clogged with wooden cork. At the completion of the work, this part is removed and the sand is poured out. This is how manual profileb is made.

To assemble such a form of machine, you do not need to be an experienced builder. Implementation of all the listed recommendations will allow to avoid difficulties at the time of work, besides, there is no need to purchase expensive equipment.
