并非所有的模具(金属部件)都需要做TD处理,只有产量大,产品质量要求高,易磨损的模具部件才需要TD.然而影响模具部件的使用寿命的因素比较多。我们认为模具(金属工件)在采用TD处理时需要注意的主要事项有:


1、 设计:主要考虑在设计时尽量避免尖角和注意工件的长径比,只有R>0.5mm才能确保TDi3程中热应力和组织应力的消除,从而有效规避和减少工件在TD过程开裂和变形量过大的风险;

2、 基体材料的选用:好选择Crl2N4oV、SKD11、KD11S、DC53、D2、D6、A2等;

3、 初始热处理工艺;

4、 制适过程的控制;

5、 特殊情况下的焊补;

6、 装配、调整和使用,人、机、料、法、环的匹配。

Not all mold (metallic work pieces) need being processed by TD, only those with large production output and high quality requirements and susceptible to wear urgently need TD. However,there are many factors which may influence the service life of molds (metallic work pieces). We hold that the following main cautions should be observed when molds (metallic work pieces)are treated by TD:

1. Design:Avoid sharp edges,choosing appropriate length-diameter ratio,R needs more than 0.5mm to ensure the thermal stress and structural stress elimination,thus effectively avoid and reduce the risk of deformation and cracking of the workpiece in TD process ;

2. Selection of basis material: the Crl2MoV, SKD11, KD11S, DC53, D2, D6 or A2 etc is a best choice.;

3. Initial heat treatment process;

4. Controlling during the production process;

5. Weld repair under special conditions;

6. Assembling, adjusting and operating, and the matching of workers,machines,materials,methods and working conditions.
