NC sheet metal processing mainly includes single stamping, continuous blanking, single or continuous forming, nibbling and array forming. In this article, we will introduce the specific contents of these methods, as well as the process characteristics of sheet metal processing.
Specific content of NC sheet metal processing
Single stamping is a stamping process that includes arc distribution, grid holes, etc. in a single time. Continuous blanking is divided into continuous blanking in the same direction and continuous blanking in multiple directions. Continuous blanking in the same direction adopts the mode of die overlapping for processing, which is suitable for the processing of long holes. In contrast, multi-directional continuous blanking is more suitable for machining large holes with small dies. Single forming processing is a sheet metal processing method of shallow drawing and one-time forming according to the nature of the mold, and the single forming processing requires more times of stretching than the former, which is more suitable than the mold forming. Nibbling refers to the continuous arc punching process with small circular die and small step distance. Finally, array forming is suitable for processing multiple workpieces on large plates, and the types of workpieces can be the same or different.
The application of numerical control technology in sheet metal processing industry shows unique advantages and characteristics, which mainly includes the following aspects:
Low threshold, easy to use and less investment
First, the threshold is low, which is not only relatively simple and convenient to use, but also has less investment cost. NC sheet metal processing has its own unique advantages in the processing of all kinds of sheet metal parts, especially in the case of automatic processing of machined parts with complex and irregular shapes, or sheet metal parts. In addition, NC sheet metal can also automatically process holes of different sizes and shapes according to the requirements of the drawings, or use small punching dies to process the contour curves of various shapes with large sizes in the way of small step punching.
Compared with traditional sheet metal metallography, the die used by NC sheet metal technology is simpler, but the processing range is wider and the processing capacity is stronger. For sheet metal parts with special processing requirements, such as shallow stretching, flanging holes, etc., as well as large-scale processing needs, it can also win, and create good economic benefits for processing enterprises.
Stable quality and high machining accuracy
The product quality of NC sheet metal processing is more stable than that of traditional sheet metal processing, and the processing accuracy is also higher. The workpiece processed by NC sheet metal has better flatness than the traditional sheet metal workpiece, higher punching accuracy and less burr. The stability and accuracy of product forming quality have been well strengthened.
The processing speed is greatly improved
Using automatic control system for NC sheet metal processing can realize the small batch processing of the same workpiece and the simultaneous processing of different parts, and the processing speed is faster than that of traditional sheet metal. This function effectively improves the efficiency of sheet metal processing. In addition, NC sheet metal processing also reduces the subsequent processing and other links, and realizes the NC integrated processing of sheet metal parts, which greatly improves the production efficiency and reduces the input of production costs.
