What different processing techniques can a flat flanging machine achieve by replacing the mold?

The basic function of a flat flanging machine is to flatten and flanging metal cans, and it is mainly used in the production of containers such as food cans, beverage cans, and chemical cans. In the canning process, the can body and the bottom cover or top cover need to be sealed and connected through a flanging structure. The machine accurately flattens or flanging the can body port through the cooperation of the upper and lower molds to ensure that the flanging size is uniform and consistent, so as to meet the subsequent sealing, welding or rolling process requirements. This function is one of the core processes in the canning industry and directly affects the sealing performance and structural strength of the can body.

The bottom folding process is mainly used for flanging the bottom of the can body to ensure that the bottom cover can fit closely with the can body. In the canning process, the bottom of the can usually needs to go through flanging, curling and other processes to form a complete sealing structure. By replacing the dedicated bottom folding mold, the flat flanging machine can accurately bend or curl the edge of the can bottom to meet the specified angle and size requirements. This process can not only improve the sealing of the can body, but also enhance the stability of the overall structure. It is suitable for the strict requirements of packaging containers in the food, chemical and other industries.

After replacing the punching die, the flat flanging machine can be used for punching metal sheets to make metal sheets of various shapes, such as round can lids, square gaskets or other special-shaped workpieces. The punching process uses the shear force of the die to accurately cut the metal sheet, which is suitable for the production of small batches or small and medium-sized workpieces. This process has the characteristics of high efficiency and precise size. It is widely used in hardware, electronics, packaging and other industries, especially for processing scenarios that require fast die change and flexible production.

The trimming process is mainly used to remove burrs and excess edges of workpieces after stamping or stretching to improve the accuracy and aesthetics of the product. In canning or hardware processing, irregular burrs often appear on the edges of workpieces after stretching, stamping and other processes, which affects subsequent assembly or use. The flat flanging machine can precisely trim the edges of the workpiece by installing a trimming die to ensure that the cut is flat and smooth. This process can not only improve product quality, but also reduce the workload of subsequent grinding or secondary processing and improve production efficiency.

The bending process is suitable for bending and forming metal sheets, and can be used to produce various sheet metal parts, brackets, metal boxes and other products. By replacing the bending mold, the flat flanging machine can apply precise pressure to the metal sheet to bend it at a set angle or shape. The process can adjust the bending angle and arc according to needs and is suitable for processing metal materials of different thicknesses. The workpieces after bending are widely used in the fields of construction, home appliances, auto parts, etc., with the characteristics of stable structure and precise forming.
