The Core Concept of Parametric Design for Medical Equipment Micro Screws
2026,08,19
The essence of parametric design for
Medical Equipment Micro Screws is to transform the key elements of an Medical Equipment
Micro Screws into dynamically adjustable parameters and establish rules governing the relationships between these parameters. Core parameters can be categorized into three types:
1. Geometric parameters: including punch diameter, die fillet radius, punch-die clearance, and blank holder size, directly determining the structural form of the Medical Equipment Micro Screws;
2. Process parameters: such as the number of draws, blank holder force, drawing speed, and lubrication conditions, affecting forming quality and efficiency;
3. Material parameters: the yield strength, elongation, and hardening index of the sheet metal, serving as the basis for parameter relationships.
These parameters are not isolated but rather mutually constrained through process theory and empirical formulas.
For example, the punch-die clearance is typically 1.1 to 1.3 times the material thickness, and the die fillet radius needs to be adjusted based on the material elongation and drawing depth to prevent sheet metal cracking or wrinkling.
