Here are some tips for buying a C Frame Mechanical Punch Press (J21):
- Understand How Punch Press Works: The design of a punch press is based on the principle of converting circular motion into linear motion. The flywheel is powered by the main motor, while the gears, crankshaft, or eccentric gear, and connecting rod are driven by the clutch to produce the linear motion of the slider.
- Know the Classification of Punch Press: Punch presses can be classified by slider driving force into mechanical and hydraulic types. They can also be classified by slider movement into single-action, double-action, and triple-action. Lastly, they can be classified by slider drive mechanism into crank press and C-frame press.
- Consider the Manufacturer: Look for manufacturers with experience in the field of mechanical press production. They should have a strong R&D team that carefully designs every part of their mechanical punch.
- Check for Quality Guaranty: Ensure that the manufacturer provides a quality guaranty for their machines.
- Consult with Professionals: Consult with professional sales teams to select the right machine for your needs.
Remember, the major drawback of C-frame presses is that the asymmetrical body leads to deformation of the front and back openings of the body during punching, which affects the parallelism of the tooling. As a result, C-frame presses are typically used at only about 50% of their nominal capacity.
