Trumpf presents new entry-level machine at EuroBLECH 2016

With needs of an economical, compact and automation-friendly punching machine in mind, Trumpf will be presenting a new entry-level machine at EuroBLECH 2016 (Hall 11 – Stand B94).

The TruPunch 1000 can also be expanded into a TruMatic 1000 fibre punch laser machine, allowing sheet metal processors to upgrade their machine to keep pace with their growing business.

With its expandable functionality, Trumpf recommends the TruPunch 1000 as an effective entry point into professional punching. It can handle sheets up to 6.4mm thick at rates of up to 600 strokes a minute, yet is also compact. With a footprint of 6.5m x 4.9m, the TruPunch 1000 stand-alone machine is around 15% smaller than its predecessor.

Thomas Herberger, managing director of Herberger Metallwaren, a company that participates in the product testing program of Trumpf, explained: “The space we have here is limited, but the compact TruPunch 1000 slotted into the same space previously occupied by a Trumatic 200. Now we can process medium-format sheets without having to reposition them, and that really speeds up our production process.”

As their business evolves, sheet metal processors sometimes require a greater variety of parts that can be manufactured by a combination system – and with the TruPunch 1000 there’s no need to buy a second machine. Due to its modular design, the TruPunch1000 can be retrofitted with a laser cutting system, a laser evacuation unit and a beam guard system.

A 3kW TruDisk solid-state laser can be connected up to convert the TruPunch 1000 punching machine into a punch laser machine. This configuration matches the other recent addition to Trumpf’s product range: the TruMatic 1000 fiber.

This is the first time Trumpf has offered a combination machine in the entry-level segment, a move that makes it easier for customers to make the switch from purely 2D laser processing to punch laser technology. Customers who already have a TruDisk solid-state laser can also use this to operate the TruMatic 1000 fibre via the Trumpf laser network.

Redesigned drive technology

Both the new models in the 1000 range offer redesigned drive technology, which is crucial to the success of the modular concept. The advanced engineering team of Trumpf came up with the new drive, the patented “Delta Drive”, to facilitate the construction of smaller machines and open up new methods of material handling.

The Delta Drive eliminates the need to move the sheet and work table in the y-axis – normally an integral requirement of sheet metal processing. It achieves this by making the punching head quickly manoeuvre in that direction.

This new approach involves a drive system that is powered by two servomotors. When the servomotors move in the same direction, they allow the punching head to move back and forth in the y-axis. And when the ball screws rotate in opposite directions, this activates the punching stroke. The y-axis can be accelerated far faster in this arrangement, because the punch drive is also used for travel motion, eliminating the need to move the sheet or work table. As a result, the punching process is more dynamic and the machine is more productive. Furthermore, the lower relative movement between the machine table and the metal sheet reduces the risk of jamming and collisions, making the process more reliable overall. Finally, the stationary machine table significantly reduces the size of the machine’s footprint.

Automatic sorting

Both the TruPunch 1000 and the TruMatic 1000 fiber can automatically sort finished parts measuring up to 180mm × 180mm. All processed parts are sent down a chute into a sorting unit which moves in a linear direction. From there they can be sorted into a series of boxes (up to 4 different 400mm × 300mm boxes). The boxes are positioned below the machine, which provides easy removal by the operator.

Due to the movement of the punching head, the machine also offers an alternative way to remove the parts. This second method comprises an additional big flexible parts flap, which is available as an optional extra for the TruPunch 1000 and fitted as standard in the TruMatic 1000 fibre. The flap can be equipped with a sensor that detects whether all the parts have been properly ejected from the machine’s working area.

Mr Herberger commented: “Often we fill sheets with just four to six parts, and in the past we had to remove and sort them manually. But with the TruPunch 1000 nobody has to keep watch over the process because the machine simply ejects the parts through the generously sized flap and places them straight in the crate for us!”

Compact yet safe

Trumpf was also determined to make the TruMatic 1000 fibre as compact as possible. One way the company achieved this was by developing a special space-saving beam guard system that is compatible with the machine’s modular concept. This protective housing is gathered closely around the machine table in a skirting manner. In punching mode it moves downwards, giving the operator a direct and unobstructed view of the process. But as soon as the program switches to laser processing, the protective skirt rises and a hood is lowered over the Delta Drive, to which the laser processing unit is attached.

This protective screen effectively intercepts the small amount of scattered that could potentially escape at a shallow angle below the work table brushes during production. There are also two laser safety screens that allow visual monitoring of the ongoing process.

Intelligent automation and control

Both machines from the 1000 product series can be connected to the new SheetMaster Compact. This automation system loads small and medium-format sheets and blanks and unloads microjoint sheets and scrap skeletons. Thanks to its optimised loading cycles, it can reliably complete most of these tasks while the machine is in operation. Both machines are equipped with an intuitive touchscreen. The MobileControl app can also be used to operate the machines from a tablet. The TruTops Boost Punch software is required for programming, but both the license and maintenance agreement already come with the machines as standard.
