Gooseneck Style Upper Punch for Sheet Metal Bending

Packaging machine serrated blades are cutting tools installed on automatic packaging equipment, primarily used to cut or seal flexible packaging materials such as packaging film, plastic film, aluminum foil composite film, and paper. They play a key role in packaging production lines in industries such as food, pharmaceuticals, daily chemicals, and electronics, directly impacting the appearance quality and production efficiency of finished products. The packaging industry uses blades to cut or trim materials such as cardboard, plastic film, and foam. They are used in packaging machines and equipment such as slitting machines, die-cutters, and laminating machines.

The standard gooseneck upper die for bending machines is a commonly used type of upper die widely applied in sheet metal bending processes. Its unique gooseneck (C-shaped) structure effectively avoids interference with the edges of already formed workpieces, making it particularly suitable for multi-stage bending, complex shapes, and deep box-shaped workpieces. This die combines versatility and practicality, making it an indispensable basic tool in the sheet metal processing industry.

The 30-degree American-style press brake upper die is a high-precision press brake die designed according to American standards. It is commonly used in sheet metal processing applications where high accuracy in bending angle and consistent forming are required. Its 30-degree sharp angle structure allows for a smaller inner radius during bending, making it suitable for precision bending of various materials such as stainless steel, carbon steel, and aluminum plates. It is one of the standard upper dies commonly used in CNC press brakes.

The self-centering 2V bending die is a versatile and highly stable lower die type, featuring a double V-groove structure and self-centering positioning design.  It is adaptable to bending operations across a range of sheet metal thicknesses. Widely used in high-standard sheet metal processing, this die ensures consistent bending centers and precise angles, improving production efficiency. It is a very common die configuration in precision bending applications.

The T-V type bending die is a special lower die structure designed for high-precision sheet metal bending.  It utilizes a combination of a "T" shaped support and a 30° V-shaped opening, providing superior centering capability and stability. Its structure offers uniform support and precise positioning during the bending process, making it particularly suitable for bending thin sheets or workpieces requiring high surface quality. It is a commonly used high-performance die type for fine processing applications on CNC bending machines.

The four-groove bending machine die is a versatile and quickly interchangeable lower die designed with four different V-groove openings, accommodating various sheet metal thicknesses and bending angles. By rotating the die, the appropriate V-groove size can be selected, reducing the time spent on frequent die changes and significantly improving operational efficiency. It is one of the commonly used and highly efficient general-purpose dies in sheet metal processing plants.

The standard bending machine punch (88° 100mm) is a versatile upper die for CNC bending machines.  Designed with an 88° angle and a standard 100mm height, it is suitable for conventional straight bending of various thin and medium-thickness sheet metals. This type of punch is widely compatible with different brands of bending machines, easy to install, and provides stable bending angle control. It is the most widely used and frequently replaced standard upper die type in sheet metal production.

The bending machine upper die (85° / 67mm height) is a versatile upper die configuration suitable for high-precision standard bending processes.  Featuring an 85° blade angle and a compact 67mm height design, it enables stable and controllable bending angles and reduces springback deviation when processing thin materials. This die boasts strong compatibility and a long service life, making it a standard stock item for sheet metal processing plants, and is particularly well-suited for daily mass production on standard CNC bending machines.
