Core Principles of Glasses And Clocks Micro Screws Design
2026,08,12
1. Stiffness Matching Principle
The stiffness of the Glasses And Clocks
Micro Screws must match that of the main mold components (such as the die and punch) to avoid localized deformation due to insufficient stiffness or excessive stiffness increasing mold weight. Generally, the elastic modulus of the Glasses And Clocks Micro Screws should not be lower than that of the mold steel (such as 45 steel or Cr12MoV) to ensure uniform pressure transmission.
2. Material Selection Principle
Glasses And Clocks Micro Screws materials must balance strength, hardness, and toughness:
High-strength alloy steels: such as Cr12MoV and SKD11, with a hardness reaching HRC58-62 after quenching, suitable for high-load Glasses And Clocks Micro Screws;
Copper alloys: such as brass (H62) or bronze, possessing good ductility and thermal conductivity, capable of buffering localized impacts and dispersing pressure (suitable for medium to low load scenarios);
Hard alloys: such as WC-Co alloys, with high hardness and good wear resistance, but higher cost, only used in Glasses And Clocks Micro Screws under extreme loads. 3. Principle of uniform stress distribution The shape and thickness of the Glasses And Clocks Micro Screws need to be adjusted according to the stress distribution of the mold: the pressure concentration area should be appropriately thickened or reinforced to ensure that the pressure is evenly transmitted along the plane of the Glasses And Clocks Micro Screws.
