【摘要】：冷冲压模具零件是一类重要的冲压方式加工的零件,常见的如凹模镶件等,在加工此类零件时,最主要的问题就是如何处理好切割零件时的变形和支撑段的修刀。目前关于这方面问题的研究已经很多,且研究出了很多处理方法。对于零件的变形,主要是依据穿丝孔的位置、装夹的方法等来进行判断处理,而对于支撑段修切的处理对零件的精度和加工会产生较大影响,因而此方面还没有得出明确结论。对凹模板的加工,如何提高模板的加工精度是主要的考虑问题。为满足此方面的要求,对在加工诸如锥度上下异形等零件时,可以利用一些先进的加工方法,比如线切割等,这样可以显著的提高加工效率、也有利于提供定位精度等,因而有较好的适用性。低速走丝线切割就是这样一种加工技术,其可以较好的满足高精度的异形零件加工要求,对一些复杂的异形模板零件等也有很高的适用性。目前这种加工技术在模具和机械制造领域发挥了重要的作用,对提高模具加工精度,促进机床行业的发展也有一定的积极的推动作用。在利用低速走丝线切割机床进行零件加工时,需要进行计算机编程,并通过程序设计来完成起割点的选择、切割参数的设置等相关的任务,这样才可以确保机床顺利的实现相关加工目的。电机转子定子模具的结构和形状较为复杂,其加工难度也很大,而低速走丝线切割可以较好的满足其加工要求,对其中的凹模板、异形凸模、等零件可以精确的加工,因而本文主要是利用这种技术来对电机转子定子模具进行加工。
[Abstract]:Cold stamping die parts are a kind of important stamping parts, such as concave die inserts and so on. The most important problem is how to deal with the deformation of cutting parts and the repair of support section.At present, there has been a lot of research on this issue, and many methods have been developed.For the deformation of the parts, it is mainly based on the position of the piercing hole and the method of clamping, etc., but the cutting treatment of the support section has a great influence on the precision of the part and the trade union, so no clear conclusion has been reached in this respect.How to improve the machining accuracy of concave formwork is the main consideration.In order to meet this requirement, some advanced processing methods, such as wire cutting, can be used in machining parts such as taper up and down profiled, which can significantly improve the processing efficiency and provide positioning accuracy.As a result, there is a better applicability.Low-speed wire cutting is such a processing technology, which can better meet the requirements of high-precision special-shaped parts processing, and also has a high applicability to some complex special-shaped formwork parts.At present, this kind of machining technology has played an important role in the field of mould and machine manufacture, and has also played a positive role in improving the precision of die processing and promoting the development of machine tool industry.In the process of parts machining with low speed wire-cutting machine, it is necessary to carry out computer programming, and through programming to complete the selection of cutting point, the setting of cutting parameters, and other related tasks, such as the selection of cutting point, the setting of cutting parameters, and so on.Only in this way can we ensure that the machine tool can achieve the related processing purpose smoothly.The structure and shape of the stator die of the motor rotor are more complicated, and the machining difficulty is also very great. The low-speed wire cutting can meet the requirements of machining, and the concave template, special convex die, and other parts can be accurately processed.Therefore, this paper mainly uses this technology to process the stator die of motor rotor.
