Der Unterschied zwischen Biegen und Falten

Bending And Folding

Bending And Folding In recent years, 30% of the sheet metal factories in Europe and the United States and other developed countries have begun to use the folding machine to replace the traditional bending machine for part of the sheet metal bending. Compared with the bending machine, the folding machine is a bending equipment with many advantages, which is more convenient to operate. In this paper, making a simple introduction bending machine and folding machine, the figure below is the difference between the working principle of bending machine and folding machine. Bending And Folding

Biegemaschine

Bending machine is divided into hydraulic bending machine and CNC bending machine, according to the mode of motion can be divided into up and down. According to the synchronous mode, hydraulic bending machine can be divided into torsion shaft synchronous and electric hydraulic synchronous. Bending And Folding

Numerical control bending machine realizes the bending function by controlling the slider stroke and back stop of the bending machine. When using CNC bending machine, as long as the part drawing of the work piece and the bending angle of each step are input, the bending machine will be realized one by one according to the input steps. The advanced CNC bending machine mainly adopts electric hydraulic servo system and grating ruler to form full closed-loop control, with high synchronous control precision, bending precision and repositioning precision.

In use, the CNC bending machine can be operated flexibly, which can realize the super long plate processing by double machine linkage, and can process parts by single machine operation. This not only improves the use efficiency of the bending machine, but also reduces the energy consumption. The bending machine comprises a bracket, a worktable and a clamping plate. The worktable is composed of a base and a pressing plate and is arranged on the bracket; The base is composed of a base shell, a coil and a cover plate, which is connected with the clamping plate through a hinge.

The coil is placed in the depression of the base shell, and the top of the depression is covered with a cover plate. When in use, the coil is electrified by the wire, and after being electrified, the pressing plate is attracted, so as to realize the clamping of the thin plate between the pressing plate and the base. The bending machine can meet the needs of various work pieces by replacing the bending machine mold. Bending And Folding

• Working characteristics of bending machine Bending And Folding

1. The requirements for operators are relatively high and the operator is required to position the bending flange. Bending And Folding
2. The operator must hold the material. Bending And Folding
3. The side with large material area is placed outside the bending machine. Bending And Folding
4. For the bending of large work pieces, it is difficult for one operator to complete, which requires two or more people to work at the same time. Bending And Folding

• Determinants of bending angle of bending machine Bending And Folding

1. Stroke of slider. Bending And Folding
2. Mold size. Bending And Folding
3. Change of material thickness. Bending And Folding
4. The quality of supporting materials for operators. Bending And Folding

Faltmachine

Folding machine is a simple bending machine, divided into manual folding machine and pneumatic folding machine. Bending And Folding

Folding machine is a kind of machine to process the edge of products. It is used to produce stainless steel sheet products with simple shape in a large scale. However, with the continuous updating and maturity of technology, these products are produced by cold bending punch. The folding machine uses the model with bending radius to fix the steel plate on the worktable of the machine tool, and the protruding part of the material is placed on the movable worktable, which can rotate along the center of the bending radius. Bending And Folding

When the movable table rises, the stainless steel can be bent to the required angle. When bending, because the stainless steel will slide on the worktable, in order to prevent material scratch, on the one hand, the worktable surface should be smooth, on the other hand, a layer of plastic film should be pasted on the stainless steel surface to prevent work piece scratch. The upper beam of the folding machine is usually made into a wedge to form a gap, so that the blank with proper shape can be folded into a quadrilateral box or groove. Typical legend of folding machine is shown in the figure below. Bending And Folding

1. Die technischen Anforderungen an die Betreiber sind nicht hoch.
2. Beim Falzen wird der Bogen auf den Anschlagtisch gelegt, um den Falzabstand zu gewährleisten und den Bogen zu halten. Im manuellen Modus wird die Sicherheit des Falzmaschinenbedieners stark verbessert.
3. Small plate thickness error will not affect the bending accuracy. Bending And Folding
4. Die Abkantmaschine kann auch auf sehr kleinem Raum falten, und das Abkanten unterschiedlicher Blechdicken muss nicht die Form wechseln, hat also gewisse Vorteile beim großen Bogenbiegen.
5. Small edge width, low cost. Bending And Folding

1. Before operation, wear tight protective clothing, fasten the cuffs, keep the lower hem of the jacket open, and do not wear, take off or change clothes beside the machine tool, or put cloth around the body, so as to prevent the machine from wringing. Must wear a helmet, braids should be put into the hat, not to wear skirts, slippers. Bending And Folding
2. Die Faltarbeiter sollten über eine gewisse Fachausbildung verfügen, den Aufbau und die Leistung der von ihnen betriebenen Werkzeugmaschine verstehen und die Form richtig installieren, damit sie unabhängig arbeiten können.
3. Add lubricating oil before use, and check the empty car for two minutes. Bending And Folding
4. Nach dem Start sollte es warten, bis die Laufgeschwindigkeit normal ist; Beobachten Sie gleichzeitig die Dynamik des umgebenden Personals, um Verletzungen zu vermeiden.
5. Do not use the machine beyond the specification. Bending And Folding
6. Welding scar and big burr are not allowed on the material to prevent mold damage. Bending And Folding
7. Wenn das Werkstück umgedreht oder vorwärts oder rückwärts bewegt wird, müssen die Bediener auf beiden Seiten engen Kontakt halten und sich gleich verhalten.
8. Unterbrechen Sie nach der Arbeit die Stromversorgung, leisten Sie gute Arbeit bei der Maschinenwartung und der Umweltreinigung.

• Funktionsprinzip der Falzmaschine

Das obere Balkenstück ist in der Regel keilförmig, um einen Spalt zu bilden, so dass es mit einem formgerechten Zuschnitt zu einem vierseitigen Kasten oder einer Nut gefaltet werden kann.

Falzmaschinen werden oft verwendet, um eine breite Palette von Produkten aus einfachem Edelstahl oder verzinktem Blech herzustellen, aber diese Produkte werden meistens durch Kaltbiegestanzen hergestellt.

• Anwendung der Falzmaschine in HLK-Luftkanalindustrie

Die Falzmaschine ist in der Lüftungsrohrindustrie in Flachfalzmaschine und Plattenfalzmaschine unterteilt. Die Falzmaschine mit flacher Kante wird zum Biegen von Blechen verwendet, und die allgemeine Blechfalzmaschine verwendet eine gezackte Matrize, die hauptsächlich zum Biegen des quadratischen Luftkanals des gemeinsamen Blechflansches verwendet wird.

Die Optimierung des gesamten Produktionsprozesses ist der Wunsch jedes Unternehmens, denn durch die Optimierung des Produktionsprozesses kann letztendlich die Senkung der Personalkosten, die Verbesserung der Arbeitseffizienz und die Genauigkeit der Produktionsqualität erreicht werden. Daher ist die richtige Führung und Verwendung der Biegemaschine in der Blechindustrie mit der Vertiefung des Verständnisses der Menschen für Biegemaschinen und Biegemaschinen eine Richtung der Verbesserung des Biegeprozesses. Und wie man die geeignete Biegeausrüstung wählt, hängt von der Anwendung der Maschine und der Dicke des Materials usw. ab.
