金型製造では注意が必要な問題がたくさんあります. そのプロセスと要点がわからない場合, 次の知識についてもっと学ぶ必要があります.
1) 金型製造用のダイス鋼を選択する上で最も重要で決定的な要因は何ですか?
金型製作
成形方法 – 2種類の基本素材から選択可能.
- NS) 熱間工具鋼, ダイカスト中の比較的高温に耐えることができます, 鍛造と押出.
- B) 冷間工具鋼, which is used for blanking and shearing, cold forming, cold extrusion, cold forging and powder pressurized forming.
プラスチック – Some plastics produce corrosive by-products, such as PVC plastics. Condensation, corrosive gases, acids, cooling/heating, water or storage conditions caused by long shutdowns can also cause corrosion. In these cases, stainless steel die steel is recommended.
Mould Size – Pre-hardened steel is often used in large-size mould. Integral hardened steel is often used in small size mould.
Mould life – Long-term use (より多い 1000000 タイムズ) should use high hardness steel, its hardness is 48-65 HRC. Pre-hardened steel should be used for moderately long-term (100,000 に 1,000,000 タイムズ) mould with a hardness of 30-45 HRC. Short-term use (表面粗さ – Many plastic mould manufacturers are interested in good surface roughness. When sulfur is added to improve metal cutting performance, the surface quality will decrease. Steel with high sulphur content also becomes more brittle.
2) What are the primary factors affecting the machinability of materials?
The chemical composition of steel is very important. The higher the alloy composition of steel, the more difficult it is to process. As carbon content increases, metal cutting performance decreases. The structure of steel is also very important for metal cutting performance. Different structures include forged, cast, extruded, rolled and machined. Forgings and castings have very
difficult surfaces.
Hardness is an important factor affecting metal cutting performance. The general rule is that the harder the steel is, the more difficult it is to process. High-speed steel (HSS) can be used to process materials with hardness up to 330-400 HB; high-speed steel + TiN coating can process materials with hardness up to 45 HRC; and for materials with hardness 65-70 HRC, cemented carbide, ceramics, cermet and cubic boron nitride (CBN) must be used.
Non-metallic impurities generally have a negative impact on tool life. 例えば, Al2O3 (alumina), which is pure ceramics, has strong abrasion resistance.
The last one is residual stress, which can cause problems in metal cutting performance. It is often recommended that the stress release process be carried out after rough processing.
3) What parts does the production cost of mould manufacturing consist of?
Roughly speaking, the distribution of costs is as follows:
Cutting 65%
Workpiece material 20%
熱処理 5%
Assembly/adjustment 10%
It is also very clear that good metal cutting performance and excellent overall cutting solutions are important for the economic production of mould.
