以一种铝合金材料的直管单端缩口型零件为对象,设计并制造了能够满足连续生产并适应多工位机床特点的模具。通过分析该零件的成形特点和机床运动特性,模具采用主体盘式结构。成形模具通过机床凸轮动作实现卷圆功能,顶出装置实现圆管直角转向,主体盘以导向圆盘为转动中心做回转运动,带动整形刀具和缩口成形模进行直管的整形和单端缩口,出口端设置红外检测装置,异常情况自动停机保护。经过调试,模具工作情况正常,制件尺寸符合图纸要求,工作速度达到预期目的,首批连续生产后全部达到要求。
Designed and manufactured to meet the requirements of continuous production and multi-station machine tools, a straight-type single-end necking-type part of aluminum alloy material was designed and manufactured. By analyzing the forming characteristics of the part and machine tool movement, the mold adopts the main disc structure. The forming die achieves the rounding function through the cam action of the machine tool. The ejecting device realizes the turning of the round tube at right angles. The main body disc rotates with the guide disc as the rotating center to drive the shaping tool and the shrink- The mouth, exit set infrared detection device, abnormal shutdown automatically protection. After debugging, mold work is normal, the size of the workpiece in line with the requirements of the drawings, work speed to achieve the desired purpose, the first batch of production to meet all the requirements.
