The structural principle of the corner rounding machine is primarily based on mechanical components or pneumatic/hydraulic drive systems that perform rounded corner cutting on the edges of raw materials, making them more aesthetically pleasing and safer. Below is an overview of its basic structural principles and working process:
I.Basic Structural Components
1.Cutter System (Cutting Blade)
·Typically consists of arc-shaped blades or mold-type corner cutters, customized according to the required corner radius.
·Can be fixed, adjustable, or interchangeable types.
2.Drive System
·Mechanical drive: Such as foot pedal or manual push rod to drive the cutting mechanism.
·Pneumatic drive: Uses air cylinders to drive the punch down quickly to complete the cutting.
·Hydraulic drive: Provides greater pressure for thicker materials.
3.Positioning Device
·Ensures consistent cutting position each time; may include limit stops, guide rails, or sliding grooves.
4.Worktable Surface
·Flat and wear-resistant, sometimes equipped with scales or positioning holes for easier operation.
II.Working Process
1.Place the material at the designated position on the worktable.
2.Align the edge of the material with the cutting die.
3.Activate the drive system (e.g., press the foot pedal/start the air cylinder).
4.The cutter presses down to complete the corner rounding.
5.The cutter resets, and the rounded material is removed.
III. Applicable Materials
·Suitable for corner rounding on materials such as PVC sheets, paper, business cards, labels, stickers, acrylic, and plexiglass.
·Different materials may require different cutting forces and blade angles.
Example
·For instance, a manual corner rounding machine is suitable for trimming business card corners:
·Interchangeable die sizes such as R5, R10, and R15.
·Manually press down the handle to activate the blade and quickly create a standard rounded corner.
·Can cut thicknesses of 0.5-1 mm at a time.
