Metal Forming & Fabricating Showcase Two

Our second review of some of the latest metal fabrication machinery, systems and accessories.

Heavy Gage Cut-To-Length Plate Lines from Red Bud can process material thickness up to .750 in at material widths up to 96 in and coil weights up to 90,000 lb.
Stretch Leveling systems from Red Bud stretch the material sufficiently to exceed the yield point in all the fibers of the strip from top to bottom and from edge to edge, thus equalizing internal trapped stresses throughout the material to produce flat material that stays flat even after laser cutting, notching, punching, or subsequent shearing operations.
This Horizontal MetalMaster with 2-bar partial pressure from Ipsen will be used to process engine parts inside a 24 in x 24 in x 40 in all-metal hot zone with a 1,500 lb load capacity. It operates at 1,000 deg F to 2,200 deg F with ±10 deg F temperature uniformity.
This TITAN H2 with 2-bar quench from Ipsen is being used by a continuous casting manufacturer to process printed steel part prototypes as part of a collaborative 3D printer-furnace package.
The novel rotary draw Evbend 1000 CNC tube bending machine from Unison can greatly reduce costs of small-batch production, prototyping, and repair or reverse-engineering. Manual operations are used to feed and rotate the tubing and apply the bending force, but a smart CNC controls the braking on the carriage feed, rotation and bend arm axes to form part shapes to the highest accuracy.

HEAVY GAGE CUT-TO-LENGTH PLATE LINES
Red Bud Industries (Red Bud, IL) is a leading manufacturer of heavy duty Heavy Gage Cut-To-Length Plate Lines that include unique features that minimize personnel and reduce set up time and material handling, optimize throughput and produce more tons per hour. These Heavy Gage Cut-To-Length Plate Lines can process material thickness up to .750 in (19 mm) at material widths up to 96 in (2,438 mm) and coil weights up to 90,000 lb (41,000 kg). These systems include state-of-the-art guarding and an industry leading 5-Year Warranty. Line equipment includes:

  • Coil storage/Dual Uncoiler with regenerative drive braking
  • Coil prep area/fully automatic “hands free” coil loading
  • “Deep plunge” heavy gage plate flatteners with “pop top”
  • Brush/vacuum Dust Collector
  • Heavy Gage Grip and Roll Feeds
  • “Accu-Square” Shears
  • High Speed Drop Stacker with “scrap puller”
  • “Lift Type” Conveyors

An In-Line Stretcher Leveler with Suregrip® technology can also be incorporated into a Cut-To-Length/Blanking Lines to produce panel flat stress reduced blanks. The Stretcher Leveler stretches the material sufficiently to exceed the yield point in all the fibers of the strip from top to bottom and from edge to edge, thus equalizing internal trapped stresses throughout the material. A Temper Mill elongates the strip 1½ percent or 2 percent, while a Stretcher completes its work with usually only .3 percent to .5 percent elongation. As a result, Stretchers have very little impact on the metallurgical properties of the material. In addition, the Stretcher Leveler will produce the ultimate in flatness, effectively removing edge wave and center buckle from the material. Suregrip guarantees there will be no slippage of the material while stretching, no matter the thickness or whether the material is oily or dry.

Stretch Leveling produces flat material that stays flat even after laser cutting, notching, punching, or subsequent shearing operations. In addition, these systems have a lower initial purchase price, as well as a lower maintenance cost, than Cut-To-Length Lines utilizing Temper Mills. Besides providing “dead” flat blanks for use in critical cutting and welding applications, the Stretcher Leveler can be used to efficiently reclaim secondary material and convert it to prime. Red Bud has been building Stretcher Levelers since 1986 and has sold almost 40 Stretchers sold worldwide. These systems are rated at material thicknesses up to .750 in (19 mm) at widths up to 96 in (2,438 mm).

HIGH PRECISION TUBE BENDER FOR SMALL-BATCH & PROTOTYPE PARTS
Unison Ltd. (Scarborough, UK) offers what is believed to be a unique concept on the tube bending automation market: the Evbend machine greatly reduces the entry costs to precision rotary draw tube bending by using manual operations to feed and rotate tubing and apply the bending force, but with smart CNC-controlled braking on the carriage feed, rotation and bend arm axes to ensure part shapes are formed with the highest accuracy.

This development is a re-engineered version of an existing machine called Evbend that used a concept that was originally developed by a UK engineer in the 1980s. Unison acquired the intellectual property for Evbend in February 2014 and has now re-engineered the machine to add a modern programming and operational control user interface and to enhance manufacturability. The new Evbend 1000 is the simplest high precision CNC tube bending solution available today for small-diameter tubing up to 22 mm. The Evbend bending technique – and the rigidity of the machine – are ideal for producing high-precision tubular parts in a low volume production environment. Since its introduction in the 1980s, it has attracted a large user base, with more than a hundred machines sold worldwide, predominantly into aerospace and motorsport sectors for small-batch production, prototyping, and for repair or reverse-engineering purposes.

Manual operation makes Evbend exceptionally versatile, simple and safe. There is almost no limit to the intricacy and multi-bend complexity of tubular shapes that can be formed thanks to the machine’s ultra-compact bending head and the versatility that manual operation brings to the manipulation process. However, the sheer ease of use of Evbend is probably the machine’s strongest selling point. There is no complex user interface to learn. Operators can typically grasp how the machine works within minutes.

Users can create bending programs in two ways. First, by entering the standard tube bending information (XYZ/YBC values, or the distance tube is fed out, rotated, and the angle of bend) into dialog screens on the Evbend’s Windows operator interface; this data can also be transferred from a coordinate measuring machine. Alternatively, users can program the machine using a teaching mode. This latter method is particularly powerful: it is so simple to use that a part can be reverse-engineered by bending and comparing a tube against an existing part – with the user capturing the underlying material feed, rotation, and angle of bend information as the desired points are reached.

Once the bend data is entered the user can start bending parts, under the interactive guidance of the machine. Evbend’s new touch-screen HMI displays the actions required in sequence, with real-time feedback of positional data as tubing is fed, rotated or bent. The precision and repeatability of these feed, rotation and bending operations is assured by a smart electromagnetic braking system. Encoder feedback on each axis ensures that all movements are made with extreme precision. Evbend’s pneumatically controlled mandrel is automatically applied during the bending cycle, with programmable control over mandrel withdrawal.

The standard machine is supplied with a right-hand bending head. However, Evbend can also perform left-hand bending with the addition of an optional second bending head. The major element of the upgrade to the Evbend machine is the provision of a state-of-the-art Windows HMI that replaces a previous dedicated controller and operator interface that required the connection of a separate PC to run the bending program database. The new HMI meets the demands of existing users for a fully integrated machine and brings many attractive new features to this tube bending machine concept, including greatly improved graphics, touch-screen control, simple integration into factory networks, and access to powerful CAD tools and interfaces for the automated creation of tube bending programs. The new HMI is also available as a retrofit for Evbend’s existing user base in aerospace, motor racing and other precision tubular manufacturing sectors.

“We are truly delighted to have secured the rights to this versatile precision bending machine. It’s a great complement to our well-known range of all-electric tube benders,” says Alan Pickering, the chief executive officer of Unison. “We have not yet found a part shape that cannot be formed on the machine, and the addition of our new HMI substantially extends the ease of use and production efficiency of the machine.” The company is also working on a larger version of the Evbend machine that will apply power assistance on the bending axis to allow tubing of up to 50 mm (2 in) diameter to be manipulated.

CONCAVE BLADES CUT WIRE, ROD, TUBE, PIPE, BAR & PROFILES
The Wheelabrator Group, Inc. (LaGrange, GA) has introduced a new concave blade for its 35 Ezefit blast wheel that achieves a narrow blast pattern and a uniquely tight ‘hot spot’ at high abrasive speeds. This blade design is perfect for blast machines processing narrow workpieces, such as wire, rod, tube, pipe, bar or profile, providing better cleaning straightaway and fewer multi-passes.

The new blade with its distinct concave design has already solved a major issue at Nucor Steel’s cold-drawn bar line in Darlington, SC, where the team assembled around maintenance supervisor Stan Thompson was hoping to increase the line speed to more closely match the downstream bar draw, but their 25-year-old blast machine simply couldn’t keep up. To achieve more concentrated and efficient coverage of the small-diameter cold-drawn bar, the team initially introduced a standard direct-drive 25 Ezefit blast wheel to use with intensifier plates, but still couldn’t achieve the desired abrasive velocities or flow.

“We knew that simply installing more powerful blast wheels to achieve the high velocities we needed wouldn’t get round the problem – it would likely tear apart the machine or cause significant wear issues down the road,” noted Thompson. “What we needed was an elegant solution that would give us a clean, tight blast pattern, as well as high abrasive velocities and flow.” The concave blade was the solution that Stan had been looking for. The old machine’s four 17 BD 195 blast wheels were exchanged for four 50 hp Ezefit blast wheels with the new blades. And because the blades are now creating the narrow blast pattern on their own, any expensive intensifier plates could be removed.

The blast machine is now capable of keeping up with the downstream equipment’s line speeds and no longer presents a bottleneck in production at Nucor Steel. The concentrated blast pattern means the blast process is more efficient, leading to less abrasive consumption and better overall part cleaning. “These concave blades allow us to do something that we weren’t able to do before – and do it faster and better. But they’ve also significantly cut down our maintenance time and part costs, due to less wear and tear on the machine and a simpler set-up. The abrasive is now going exactly where we need it to go, on the bar, rather than wearing out cabinet liners and casings.”

These blades are exclusively available on 35 Ezefit blast wheels from Wheelabrator and can be fitted as part of a strategic equipment upgrade on Wheelabrator and non-Wheelabrator equipment alike.
