INNOVATIVE STRUCTURAL PROFILE TECHNOLOGY

FLEXIBILITY AND PRODUCTIVITY FOR MANUFACTURING STRUCTURAL PROFILES IN ACCORDANCE WITH NBR 6355:2012

The Purlin Rollforming Machines developed by Esquadros® has innovative and exclusive technologies for the manufacture of U and stiffened U profiles (U and C),, such as bearing synchronism, high productivity with a real speed of up to 60 m/min, cutting technology with knives that do not generate chips and the new intelligent flight stamping module.

The Esquadros® Purlin Rollforming Machines, model PE400.3, covers the thickness range from 2.00 mm to 3.20 mm, manufacturing profiles from 2" to 8" (from the U-45x17 mm profile to the C-200x75x25 mm profile), with coils weighing up to 6 (six) tons.

The profiles are produced with dimensional and geometric tolerances in accordance with the Brazilian standard NBR 6355:2012 , with high quality in the cutting and surface of the profiles, meeting even the strict quality standards required by steel distributors.

It is certainly the best cost-benefit solution on the market , as can be seen from the dozens of machines installed and in operation. More productivity and reduced operating costs, increasing the profit per ton processed.

The quick changeover of the conformation tooling on the Esquadros® machine is up to 4x faster than the conventional system , thanks to the synchronized height adjustment of the upper bearings, which provides very fast setup.

Find productivity with the Esquadros® Purlin Rollforming Machine: non-stop cutting through servomotor flying cutting and German SEW® drives that reach the real speeds of up to 60 m/min. .

Esquadros® is launching its exclusive "INTELLIGENT FLIGHT STAMPING" technological innovation on the market, which stamps already formed profiles non-stop with maximum precision and productivity, using compact, vertical and lateral stamping modules. It is possible to stamp holes, oblongs and special cut-outs for the production of a wide variety of profiles, such as: metal purlins for civil construction with mounting holes; profiles for the structure of photovoltaic panels (solar energy generation); among others.

ESQUADROS® QUICK-CHANGE SYSTEM

Understanding the importance of operational flexibility for a machine that must produce different profiles, the Esquadros® Purlin Rollforming Machine has a quick change system for the conformation tooling, which is up to 4x faster than the conventional system.

It has synchronized upper bearing height adjustment providing very fast setup. The height adjustment of the upper axis is made by the simple movement of a flywheel, which activates 2 (two) boxes with precision reducers, coupled and interlocked, to ensure parallel and uniforme rising/lowering at each conformation stage, requiring less experience and time of the operator to make adjustments of the thickness variations of the profiles.

EVOLUTION

For customers who already produce folded sheet metal profiles (UDC) using the conventional cutting and folding process (shears and folding machines), the investment in the Esquadros® Purlin Rollforming Machines will result in greater production capacity and a drastic reduction in operating costs, through:
• Increased productivity;
• Constant precision and quality;
• Optimizing the use of materials - eliminating scraps;
• Lower costs for acquiring materials from coils;
• Less space required for storing materials - coils;
• Easier production planning and control (PCP).
The greater supply of profiles on the market, made possible by the production capacity of the Esquadros® Purlin Rollforming Machines, could lead to increased sales, higher turnover and consequently higher profits for the business.

ESQUADROS® DIFFERENTIALS

QUICK TOOL CHANGE SYSTEM - UP TO 4X FASTER

Quick-change cylindrical conformation tooling system (up to 4x faster than the conventional system) thanks to the synchronism of the castles and the high precision of the mechanical set.

RAPID HEIGHT ADJUSTMENT OF THE UPPER SHAFTS

Synchronized upper bearing height adjustment for very fast setup. Adjusting the height of the upper shaft is done by simply moving a handwheel, which drives two (2) boxes with precision gearboxes, coupled and interlocked, to guarantee a parallel and uniform descent/ascent at each conformation stage, requiring less experience and time from the operator to make adjustments to the profile thickness variations. It also eliminates unnecessary operator movement (a waste of time), since the entire operation is carried out from just one side of the machine, making it more comfortable to operate.

ULTRA-PRECISE CYLINDRICAL CONFORMATION TOOLING

Ultra-precise cylindrical conformation tooling that does not accumulate differences during assembly and eliminates manual adjustments. Spacer bushes to centralize the tooling. All parts are laser engraved for easy identification and assembly. Detailed assembly map for the manufacture of all profiles.
