冷作模具鋼在工作時由于材料的變形抗力比較大,模具的工作部分承受很大的壓力、彎曲力、沖擊力及摩擦力,導(dǎo)致冷作模具鋼出現(xiàn)磨損或因斷裂、崩力和變形超差而失效。下面來講講冷作模具鋼的工作條件及性能要求。
The cold working die steel is worn out or fails due to fracture, collapse force and deformation out of tolerance due to the large deformation resistance of the material and the large pressure, bending force, impact force and friction force on the working part of the die. Now let's talk about the working conditions and performance requirements of cold working die steel.
冷作模具的性能要求:
Performance requirements of cold working die:
1、高硬度和高耐磨性,工作時保持鋒利的刃口。
1. High hardness and wear resistance, keep sharp edges when working.
2、較高的強度和韌性及一定的熱硬性,工作時刃部不易崩裂或塌陷。
2. With high strength, toughness and certain thermal hardness, the blade is not easy to crack or collapse when working.
3、較好的淬透性,保證淬火態(tài)有較高的硬度和一定的淬透深度。
3. Good hardenability ensures high hardness and certain hardenability depth in quenched state.
4、較好的加工工藝性和成形性,較好的淬火性,熱處理變形小,在復(fù)雜斷面上不易淬裂。
4. Good processability and formability, good quenching safety, small heat treatment deformation, and not easy to crack on complex sections.


冷作模具鋼具有高的硬度和耐磨性、高的抗彎強度和足夠的韌性,這樣才能保證沖壓過程的順利進(jìn)行。由于其工作時需要承受沖壓力,則還需要具有高的耐磨性能,又由于形狀復(fù)雜易于產(chǎn)生應(yīng)力集中,所以要求具有較高的韌性;表示模具尺寸大、形狀復(fù)雜.則要求較高的淬透性、較小的變形及開裂傾向性。
Cold working die steel has high hardness and wear resistance, high bending strength and sufficient toughness, so as to ensure the smooth progress of the stamping process. Because it needs to bear the impact pressure when working, it also needs to have high wear resistance, and because the shape is complex, it is easy to produce stress concentration, so it is required to have high toughness; It means that the mold is large in size and complex in shape. It requires high hardenability, small deformation and cracking tendency.
合理選取模具材料及實施正確的熱處理工藝是保證模具壽命的關(guān)鍵。模具材料的選用和相應(yīng)的熱處理工藝是重要因素。據(jù)資料顯示,在所有的模具失效因素中,模具的材料和熱處理約占70%的比例,成為影響模具壽命的主要因素。因此在模具的整個設(shè)計制造過程中,模具材料的選用和熱處理工藝是否適當(dāng)顯得尤為重要。更多相關(guān)信息就來我們網(wǎng)站http://www.6886774.cn咨詢吧。
Reasonable selection of mold materials and implementation of correct heat treatment process are the key to ensure the service life of the mold. The selection of die materials and the corresponding heat treatment process are important factors. According to the data, among all the die failure factors, the die material and heat treatment account for about 70%, which has become the main factor affecting the die life. Therefore, in the whole process of mold design and manufacturing, the selection of mold materials and whether the heat treatment process is appropriate is particularly important.
