Material selection of Pump Motor Progressive Die is a key factor affecting its performance and life. Choosing the right material can not only improve the durability and processing accuracy of the die, but also effectively reduce production costs and improve product quality. The following are detailed considerations and related considerations for material selection of Pump Motor Progressive Die.
1. High-strength and high-hardness materials
Pump motor progressive dies need to withstand huge pressure and repeated impacts during the stamping process, so the die material must have high strength and high hardness. Commonly used die materials include tool steel (such as D2, SKD11), high-speed steel (such as M2, M42) and cemented carbide (such as tungsten-cobalt alloy).
Tool steel: Tool steel has good wear resistance and impact resistance, and is suitable for making die parts that are subject to high stress and high wear, such as punches and dies.
High-speed steel: High-speed steel has extremely high hardness and heat resistance, and is suitable for making die parts that require high cutting speeds and high precision.
Cemented carbide: Cemented carbide has excellent wear resistance and heat resistance, and is suitable for making mold parts that require high wear resistance and high precision, especially when working in high temperature environments.
2. Wear resistance and corrosion resistance
Pump motor progressive molds will be worn and corroded during long-term use, so it is crucial to choose materials with good wear resistance and corrosion resistance.
Wear resistance: Wear-resistant materials such as Cr12MoV, SKH-9, etc. can extend the service life of the mold, reduce the need for frequent mold replacement, and reduce production costs.
Corrosion resistance: When working in a humid or corrosive environment, mold materials such as stainless steel (such as 440C) and high alloy steel (such as H13) can provide better corrosion resistance and ensure long-term stable operation of the mold.
3. Good toughness and impact resistance
During the stamping process, the mold will be subjected to repeated impact loads, so the mold material needs to have good toughness and impact resistance to avoid the material from breaking or damaging under high stress conditions.
Toughness: High-toughness materials such as SKD11, DC53, etc. can effectively absorb impact energy and reduce the risk of damage to the mold under high stress conditions.
Impact resistance: Impact-resistant materials such as SKH-51, ASP-23, etc. can maintain stable performance under high-intensity impact and ensure the long service life of the mold.
4. Heat treatment performance
The heat treatment performance of the mold material directly affects the hardness, strength and wear resistance of the mold. A suitable heat treatment process can significantly improve the comprehensive performance of the mold.
Quenching: The quenching process can improve the hardness and strength of the mold material, making it have better wear resistance and impact resistance.
Tempering: The tempering process can eliminate the internal stress generated during the quenching process, improve the toughness of the material, and prevent the mold from breaking during use.
5. Processability
The processability of the mold material is also one of the important factors to be considered when selecting materials. Good processing performance can improve the manufacturing efficiency of the mold and reduce processing costs.
Easy processing: Materials such as H13 and P20 have good cutting performance and processing stability, and are suitable for making mold parts with complex shapes and high precision requirements.
Surface treatment: Some mold materials can be further improved through surface treatment processes (such as nitriding, chrome plating) to improve their wear resistance and corrosion resistance, thereby extending the service life of the mold.
