When bending meets automation, a sublimation change in sheet metal processing!

From the end of the 1970s, with the introduction of German TRUMPF CNC stamping equipment in the military industry, my country's sheet metal processing industry began to take off. By the 1980s, the textile machinery, high and low voltage power distribution industries introduced the so-called "four major pieces" of CNC turret punch, CNC bending machine, CNC shearing machine and right-angle shear on a large scale, and established the modern sheet metal manufacturing industry standard. Today, sheet metal processing has penetrated into all sectors of the manufacturing industry. The continuous generation and development of new technologies and new processes has brought about huge changes in the sheet metal processing industry. The pressure of multi-variety, small batch, customization, high quality, short delivery time, and reduction of manufacturing cost, coupled with the huge demand of the terminal market, is forcing sheet metal terminal enterprises to make changes in management and technological innovation . Market changes have brought about changes in the industry and new opportunities for automation. As an important process, bending has attracted more and more companies to enter or accelerate the layout, and a new market game is being formed.

With the wide application of bending parts in mechanical products, in order to meet its product quality and production needs, its quality standards have gradually improved. Exactly what kind of process is needed for sheet metal processing in the new market environment, and the development trend of sheet metal processing to mechanical automation has become an inevitable move. The rhythm balance between the upper and lower processes of the processing unit is particularly important to eliminate bottlenecks and improve the production efficiency of the bending process. Focusing on the problems of automatic bending and low riveting of sheet metal, Zhengzhou International Machine Tool Exhibition brings together excellent bending machines at home and abroad. Manufacturers bring a bending feast to the central manufacturing industry.

Let's take a sneak peek and see what automated processes the bending companies have brought!
