How do profilegib for 2000 rubles: to note Homebrew

Fotoinstruktsiya of independent manufacturing inexpensive profilegiba of parts from old cars and bicycles, bearings, threaded studs and sill

Profilegib needed by many domestic masters. Bend metal pipes for greenhouses, to make arches carport, to manufacture roof swing - everywhere there exists application tool. But the price to purchase quality profilegib prefabricated "bite." What to do? Make a "typewriter" for bending pipes with a manual drive of inexpensive materials modeled on Pin008.

Profilegib without turning operations: the price, details, tools

Having decided to make profilegib their own hands, the master asks himself questions:

• Will I have to tokarka?
• How much will cost homemade?
• Do not buy cheaper profilegib in the store?

To answer them, just show what happened at the participant portal Pin008.

And this is an example of work performed profilegibom.

Profilegib homemade-cost 2 thousand. rub., made of 3 pm and, at the user's words, paid for itself for half a day.

And this video, which shows the work of this self-made tube bender for profile pipe.

If you are interested in a home-made CNC tube bender Pin008Then for its manufacture you will need:

• Bearing UCP node 204 - 4 pcs .;
• straight channel 8 (the height of the base shelf 8 cm, 4 cm width of the shelves) - 2 m;
• rhombic jack of the car;
• bearing 156 704 - 3 pcs .;
• M20 threaded rod;
• M20 nut;
• washer the pin M20;
• Stars from the bike - 2 pcs .;
• bicycle chain.

Tools:

• Bulgarian;
• powerful drill;
• welding inverter.

Next, we describe how these parts to collect a homemade profilegib.

Production machine for bending profiled metal pipes

Work on the construction of homemade user broke into a number of sequential steps:

• Estimated size profilegiba.

• Of the jack screw took part for making the pressure screw.

• Examples of parts.

• Collected body bending machine of channel.

• Produced videos. Axis Pin008 made of M20 threaded studs. To do this, he cut her grinder to the desired length.

Rollers fashioned from a set of nuts, bearings and washers.

• Manufacturing steps of the pressing roller.

• Assembling the frame profilegiba. The top strap is removable for ease of installation of the pressure roller.

The photo below clearly shows how to make a pressure roller for profilegiba.

Further Pin008 produced locknuts. He did it like this:

• Screw the nut on the pin and lock her second nut.
• Workpiece clamped clamp and sawed nut grinder with a thin cutting discs.

Design assembly.

Sprockets for chain drive Pin008 I picked to nuts welding.

Further Pin008 profilegib collected. I painted it and used for its intended purpose.

The finished design.

T. k. drawings homemade Pin008 did not, then, to clarify the size of the machine, he applied to profilegibu roulette.

I think, to take a smaller channel is not necessary. Weight frame drop and the machine will be unstable. Make the distance between the axes of the rollers is less than 300 mm is also not to be. Otherwise, it increases the load on the rollers, bearings, and they burst cage. I note that the course of the pressure screw is so easy, it turns one finger.

When making homemade profilegiba note that the smaller the axial distance between the rollers, the smaller the radius of the bends on the workpiece machined. But will increase the load on the rollers, and hence the bearings. Bend radius magnitude is regulated lowering the pressure roller, and it is limited by the height of the central portion of the frame and the length of the threaded portion of the pressure screw.

Tips on making profilegiba, and how to reduce the budget

Operation profilegiba showed that homemade failed and is optimally suited for bending pipes 20x20 mm. For pipes of larger size will make a design change - increase the width of the working part of the rollers and enhance the machine frame. Another point - the users interested homebrew twig, doubts about the strength and durability of the shaft made of threaded rod. But 5 years of operation, the tool proved that the idea works. According to Pin008, for all time of operation of home-made, do not break anything. The only thing he would have done that - gave up two more goals on the pressure roller. They just do not need.

A thrust bearing it would take a greater width.

Important thing! The lower rollers are not spinning relative to the studs, T. To. "Firmly" clamped on both sides of the nuts. But they revolve shafts in the outer cage - in bearings located in supports of the frame.

This prompted Pin008, both reduce the cost of construction.

To lower rollers do not buy new bearings, and look at the car repair "dead". They still do not revolve on shafts. Chain and sprocket ask around with friends, suddenly lying around "unnecessary and excessive" from junk. Pin and channel points to buy metal reception.

And here val-lel, from personal experience, I advise to look into the car repair thrown out the timing chain and camshaft sprockets from VAZ engine. All you need two identical sprockets and one chain. Even if there are traces of wear of sprockets and chain extended, for a homemade machine, it - it does not matter.

So you reduce the budget for the construction of profilegiba.
