Material Performance Requirements For Mold Insert Processing
1. Hardness
Hardness Is One Of The Main Ability Index Of Die Steel, Die Under The Action Of High Stress Can Maintain Its Shape And Dimensional Accuracy Of Ultra-Precision Parts, Must Have High Enough Hardness. Different Parts, And Different Uses Of Precision Parts, Material Demand Hardness Is Also Different. In General Fa Equipment Precision Parts, And Ultra-Precision Mold Parts, The Inspection Tools Used For Inspection Are Not The Same As The Corresponding Hardness Requirements.
2, Red Hard
Hot Metal Parts Working At A Relatively High Temperature Are Required To Maintain The Stability Of Their Organization And Performance, And To Maintain A High Enough Hardness, Which Is Called Red Hardness. Carbon Tool Steel And Low Alloy Tool Steel Usually Maintain This Property In The Temperature Range Of 180~250℃, And Chrome-Molybdenum Hot Working Die Steel Generally Maintains This Property In The Temperature Range Of 550~600℃. The Hardness Of Steel Depends Mainly On Its Chemical Composition And Heat Treatment Process.
3. Compressive Yield Strength And Compressive Bending Strength
Hardware Parts In The Use Of The Process Is Often Subjected To Strong High Pressure And Bending, So We Should Have A Certain Compressive Strength And Bending Strength Of The Material Requirements. In General, If We Want To Carry Out Compaction Test And Bending Test Conditions Close To The Actual Working Conditions Of The Die, For Example, The Measured Compressive Yield Strength Of The Die Steel Is More Suitable For The Deformation Resistance Shown By The Punch When Working. Another Advantage Of Bending Test Is That The Absolute Value Of Strain Variable Is Large, Which Can Reflect The Different Deformation Resistance Of Different Steel Types And Under Different Heat Treatment And Arrangement Conditions.
4. Toughness
In The Process Of Production, The Metal Parts Are Subjected To Impact Load. In Order To Reduce The Damage In The Form Of Breaking And Falling Blade In The Process Of Use, It Is Necessary To Adhere To The Original Ultra-Fine Precision Requirements Of Die Steel With Certain Toughness.
5. Wear Resistance
The Most Important Factor In Determining The Service Life Of The Die Is Often The Wear Resistance Of The Die Data. The Mold Accepts Relatively Large Compressive Stress And Friction Force In The Work, Requiring The Mold To Be Able To Adhere To The Scale Accuracy Of The Mold Parts Under Strong Friction. Die Wear Is Mainly Mechanical Parts Wear, Oxidation Wear And Melt Wear Three Types
