What are the common CNC folding machining processes?

Due to its free bending feature, the full-servo CNC folding machine has a lot of freedom in the development of the process. It does not need to change or adjust the mold. Through the combined action of the upper and lower folding molds and the compression mold, it can achieve a variety of Bending process, process performance is even better.

The most common is the bottom pressing and flattening process of pressing the dead edge. Anhui Yongya feels that for the folding machine, whether it is positive or reverse flattening, there is no need to turn the plate over, and the plate is directly placed on the work surface. On the top, through the conventional bending process to complete the 30°～45° angle forming, and then send the formed hemming angle to the lower die table, use the compression die to flatten it, the whole process only takes a few seconds to complete . For the need to bend after flattening, the folding machine can directly process it.

If the conventional hemming method is used, even if there are more segments, a few creases will eventually appear on the outside of the arc formed by continuous bending due to the processing mechanism of the hemming machine, which cannot meet the process requirements of some industrial workpieces. Yawei, as a senior sheet metal equipment supplier with many years of R&D experience, has finally developed a new set of arc process implementation schemes through continuous testing, which is formed by the cooperation of the folding die and the slider to make the crease Appears on the inside of the arc, will not affect the surface smoothness, and the forming efficiency has also been improved, and the appropriate arc process plan can be given according to the arc of different sizes and the accuracy requirements, and as far as possible under the premise of meeting the process requirements Save time and improve efficiency.

The advantage of folding machine processing technology is not only that it saves time, effort and money. For some seemingly simple process requirements, the structure of the conventional bending machine determines that it cannot be processed at all. For example, the side-mounted board in the figure below has only two processes on a single side, one is formed at 90°, and the other is formed with 1/4 arc. If you use a bending machine to process, first fold 90° to form, and the arc will not be processed. 1/4 arc forming, when 90° straight edge is processed again, it will definitely affect the already processed arc surface, and it can be easily, efficiently and highly accurately realized by the folding machine.
