随着国民经济的飞跃发展和社会主义革命、社会主义建设事业的迫切需要,对我厂分马力电机生产提出了新的任务和更高的要求。分马力电机出口任务增加了。我们车间制造分马力电机产品的定、转子冲片的冲模数量也就相应增多了,因此对槽形冲头和电加工凹模槽形的电极的需要量也就越来越大了。例如:一套24槽的定子冲片冲槽模,就需要有24根槽形冲头,24根电加工凹模槽形用的电极。如果是废料顶出式的模具,还需要24根槽形顶杆。冲头电极由于模具加工工艺的需要,要求保证互换,因而有一定的尺寸及几何形状精度的要求。在刨削
With the rapid development of the national economy and the urgent need of the socialist revolution and the cause of socialist construction, new tasks and higher demands are put forward on the production of horsepower electric motors in our factory. Sub-horsepower motor export mission increased. In our workshop, the number of punches for rotor horsepower is also increased accordingly. Therefore, the need for trough punches and electroformed trough electrodes is also getting bigger and bigger. For example: a 24-slot stator punch stamping die, you need to have 24 groove-shaped punch, 24 electric processing groove die electrode. In the case of scrap-out molds, 24 trough rams are also required. Punch electrode due to the needs of mold processing technology, requiring assurance of interchangeability, and therefore have a certain size and shape accuracy requirements. Planing
