創：用于纖維復合材料的沖擊器
Trumpf開發了一種新的沖擊器，這是上個能夠分離各種纖維復合材料的新型沖擊器：TruTool FCN 250.這項創新將使公司能夠利用在新應用領域中蠶食的好處。
人們傳統上主要依靠鋸，銑刀和角磨機來分離厚度為2.5毫米的纖維復合材料部件。不幸的是，使用這些工具極難實現平滑的切割邊緣和高精度的結果。此外，鋸，銑刀和角磨機會散發大量煙霧和有害粉塵。使用Trumpf nibbler分離纖維復合材料的操作員在大多數情況下使用沒有個人防護設備，因為只有少量灰塵。
它可以分離熱固性塑料和熱塑性聚合物以及碳纖維增強塑料（CFRP），玻璃纖維增強塑料（GFRP）和芳綸纖維增強塑料（AFRP）。
Trumpf是如何完成這項工程壯舉的？
Power Tools的國際銷售經理Stefan Anshelm解釋說，該公司修改了nibbler的切割幾何形狀和切割工具，以適應纖維復合材料。
“我們設法采用傳統上用于金屬加工的步沖技術，以便客戶可以將TruTool FCN 250用于纖維復合材料。”
這種沖擊器適用于任何使用纖維復合材料制造先進輕質部件的領域。例子包括航空航天，汽車和原型制造以及運動或休閑活動設備的生產。
Nibbling是一種冷加工，因為熱量不起作用。沖擊器包括沖頭，沖頭快速連續地執行沖壓沖程，以及模具，其吸收沖壓力。憑借TruTool FCN 250的高質量涂層切割工具，用戶可以創造出卓越品質的邊緣。它們還可以避免分層（層間分離）和磨損的切邊。“
易于操作的TruTool FCN 250可實現每分鐘1.9米的高工作速度。由于該工具為用戶提供了清晰的工作表面視圖，因此他們可以沿著劃線進行精確的分離切割，就像使用模板一樣。此外，用戶可以直線或半徑縮小。刀架可以360°旋轉，簡化了難以觸及區域的任務。
Trumpf TruTool FCN 250的另一個優點在于其耐磨部件的長使用壽命 - 得益于特殊涂層。例如，只需要一個模具就可以蠶食約300米的GFRP或2毫米厚的CFRP，然后才能更換; 制造商建議在約150米后更換沖頭。對于更薄的材料，使用壽命要長得多。與其他分切工藝相比，這種沖擊器的每米成本降低了50％。而且，更換沖頭很簡單，不需要額外的設備。Stefan Anshelm補充道：“與我們的薄板沖擊器一樣，用戶可以在幾秒鐘內更換我們用于纖維復合材料組件的沖頭。”
豐富的經驗表明，人們可以長時間用蠶豆切片，同時經歷很少或沒有疲勞。這在很大程度上歸功于小型打印機的緊湊尺寸和符合人體工程學的操作，其不需要用戶主動地將它們向前推過工件。Trumpf工程師進一步優化了操作頭和電機的重量分布，實現了真正符合人體工程學的手柄。
Trumpf has developed a new nibbler that is the first of its kind worldwide, capable of separating various fiber composite materials: the TruTool FCN 250. This innovation will allow companies to leverage the benefits of nibbling in new fields of application.
People have traditionally relied primarily on saws, milling cutters and angle grinders to separate fiber composite components as thick as 2.5 millimeters. Unfortunately, smooth cut edges and high-precision results are extremely difficult to achieve using these tools. In addition, saws, milling cutters and angle grinders emit a lot of smoke and hazardous dust. Operators who use the Trumpf nibbler to separate fiber composite materials use in the most of the cases no personal protective equipment as there is only a small amount of dust.
It can separate thermosetting plastics and thermoplastic polymers as well as carbon-fiber reinforced plastics (CFRP), glass-fiber reinforced plastics (GFRP) and aramid-fiber reinforced plastics (AFRP).
How did Trumpf accomplish this feat of engineering?
Stefan Anshelm, international sales manager for Power Tools, explains that the company modified the nibbler’s cutting geometry and cutting tools to accommodate fiber composite materials.
“We managed to adapt nibbling technology, traditionally used for metalworking, so that customers can use the TruTool FCN 250 for fiber composite materials.”
This nibbler is suitable for any sector that uses fiber composite materials to manufacture pioneering lightweight components. Examples include aerospace, automotive and prototype manufacturing as well as the production of equipment for sports or leisure activities.
Nibbling is a type of cold working, as heat does not play a role. A nibbler comprises a punch, which executes punching strokes in rapid succession, and a die, which absorbs the force of punching. Thanks to the high-quality, coated cutting tools of the TruTool FCN 250, users can create edges of superior quality. They also avoid delamination (interlaminar separation) and frayed cut edges."
The easy-to-operate TruTool FCN 250 achieves a high working speed of 1.9 meters per minute. Because the tool provides users with a clear view of the work surface, they can make precise separating cuts along a scribed line as if they were using a template. In addition, the user can nibble in a straight line or a tight radius. And the tool carrier can be rotated 360°, simplifying tasks in hard-to-reach areas.
Yet another benefit of Trumpf’s TruTool FCN 250 lies in the long service life of its wear parts – thanks to a special coating. Just one die, for instance, will nibble some 300 meters of GFRP or CFRP two millimeters thick before it must be replaced; the manufacturer recommends replacing the punch after about 150 meters. Service life is considerably longer for thinner materials. Compared to other slitting processes, this nibbler’s per-meter costs are lower by as much as 50 percent. Moreover, replacing the punch is simple and requires no additional equipment. Stefan Anshelm adds: “As with our thin-sheet nibblers, the user can replac the punch in our nibbler for fiber composite components in a matter of seconds.”
And a wealth of experience indicates that people can cut sheets with nibblers for a long time while experiencing little or no fatigue. This is due in large part to the compact size and ergonomic operation of nibblers, which do not require users to actively push them forward through the workpiece. Trumpf engineers have furthermore optimized the distribution in weight of the operating head and the motor, making for a truly ergonomic grip.
