摘要:

为了降低滑轮架的生产成本,根据零件的形状、尺寸、材料及生产批量要求,对滑轮架零件进行工艺分析。吸取传统工艺方案的优点,利于提高材料的利用率,制订了少废料冲裁工艺方案:将侧搭边设计为成形侧刃,应用并列成形侧刃保证零件的展开长度,没有设计中间搭边。具体步骤为:第1步切边、冲中间圆孔、冲二长孔;第2步,冲缺口;第3步,为了保证凹模的强度设计为空位;第4步,切断、弯曲,并应用倒装结构。条料的定位采用导料板,保证送料方向的直线移动以及成形侧刃与导正销的步距。最后,分析了所设计的模具结构特点与工作原理,介绍了模具设计制造要点,该模具结构简单、工作流畅、稳定,生产效率高。
 

In order to reduce the production cost of pulley frame, according to the shape, sizes, material and batch production requirements of parts, the process of pulley frame parts was analyzed. Absorbing the advantages of traditional process plan, a less waste blanking process plan was formulated to improve the utilization rate of materials. The side lapping edge was designed as the forming side edge, and the paratactic forming side edge was applied to ensure the expansion length of parts, and the middle lapping edge was not designed. The first step is trimming, punching the middle round hole and punching two long holes. The second step is punching the gap. The third step is to ensure that the strength of die is designed to be vacant. The fourth step is cutting and bending, and the inverted structure is applied. The strip material was positioned by using the guide plate to ensure the straight movement of the feeding direction and the step distances of the forming side edge and the guide pin. Finally, the structure characteristics and working principle of die were analyzed, and the key points of die design and manufacture were introduced. The die structure is simple, the work flow is smooth and stable, and the production efficiency is high.
