1. Introduction
In mechanical design, the blanking mechanism is an indispensable part. It is responsible for cutting and trimming necessary materials. The choice and application of the blanking mechanism directly influence the efficiency and cost of mechanical design.
This article introduces the commonly used blanking mechanisms in mechanical design, enabling designers to select appropriate tools according to specific needs.
2. Manual Blanking Mechanisms
Manual blanking mechanisms are the most basic way of blanking, primarily relying on human power for cutting. Common manual blanking mechanisms include hand saws and knives. These tools are suitable for small-scale, simple part blanking, with easy operation and low cost.
However, manual blanking is slow and not very accurate, making it unsuitable for large-scale production.

3. Mechanical Blanking Mechanisms
Mechanical blanking mechanisms use mechanical equipment for cutting, including shearing machines, punching presses, and laser cutting machines. These devices offer high cutting accuracy and efficiency and are suitable for batch production.
Shearing machines are suitable for metal sheet blanking, while punching presses are ideal for parts with specific shapes.
Laser cutting machines, known for their high precision, efficiency, and non-contact processing, are commonly used blanking tools in recent mechanical design.

4. CNC Blanking Mechanisms
CNC blanking mechanisms are a common method in modern mechanical design, performing automated cutting through programming.
Typical CNC blanking mechanisms include CNC shearing machines and CNC punching presses. These devices, controlled by programming, achieve precise cutting and processing, greatly enhancing production efficiency and accuracy.
Besides, CNC blanking mechanisms can handle multiple types and small batches of production, meeting the needs of modern mechanical design.

5. Robotic Automation Blanking Mechanisms
With the development of robotic technology, robotic automation blanking mechanisms are gradually being applied in mechanical design. Robots, with their high precision, speed, and lack of human interference, are suitable for high-accuracy, high-efficiency production.
Common robotic automation blanking mechanisms include welding robots and cutting robots. These robots, controlled by programming, accomplish automated cutting and processing, significantly improving production efficiency and quality.
