生产实践表明,在模锻件的设计中切莫小看了圆角,许多实例说明,它关系到整个模具设计的成败和模锻件的质量。目前,圆角半径的确定,不少设计单位或个人仍处于传统性的经验设计。其趋势是宜大不宜小,全凭设计人员的经验来确定,而尚未形成一个可遵循的统一标准。本文根据生产实践经验,即圆角值对锤锻模寿命的影响、锻模磨损损坏规律和机械加工的要求,并借鉴国外的设计标准,试总结出锤模锻件圆角半径的设计原则和选定值。 1.锻件外圆角的设计
Production practice shows that in the forging design must not underestimate the rounded corners, many examples show that it relates to the success of the entire mold design and die forging quality. Currently, the determination of fillet radius, many design units or individuals are still in a traditional experience design. The trend is appropriate should not be small, all by the designer’s experience to determine, and yet to form a uniform standard can be followed. Based on the practical experience of production, that is, the effect of the fillet value on the hammer die life, the rule of the wear and tear of forging die and the requirements of machining, and drawing on the design standards of foreign countries, this paper summarizes the design principles and selection of the fillet radius of the hammer die forging Value. 1. Forgings design of the fillet
