Introduction

Metal punching is a highly versatile and efficient process used in the shaping of metal for various applications. This article discusses the working mechanism of a metal puncher, examining its components, operational parameters, and the solutions offered by the SUNMETAL company.

Principles of Metal Punching

Metal punching is a cold working process where a tool, known as a punch, penetrates a metal sheet to create a hole by shearing. The fundamental principle is the application of sufficient force to overcome the material's shear strength.

Components of a Metal Puncher

• Punch: The component that forces into the material.
• Die: The support structure that holds the sheet in place, aligning with the punch.
• Frame: Provides the structural integrity and support for the machine.
• Actuator: The mechanism that drives the punch into the metal, often hydraulic or mechanical.

Operational Process

The metal puncher operates by a sequence of steps starting with the alignment of the punch and die. The metal sheet is placed between them. The actuator applies force to the punch, driving it through the sheet and creating a hole. The force applied typically ranges between 200 to 1,500 tons depending on material thickness and strength.

Parameters in Metal Punching

• Material Thickness: Determines the required punching force, typically between 0.5 mm to 15 mm.
• Punch Diameter: Defines the size of the hole and influences the force required, generally varies from 2 mm to 50 mm.
• Clearance: The gap between the punch and die, crucial for clean cuts and ranges from 10% to 20% of the material thickness.
• Shear Strength: The capability of the material to resist shearing, measured in MPa.
