坯料穿行弯曲模设计

A specific mould for multi-curve shape workpiece

介绍坯料穿行弯曲模,用于多弯弯曲件冲压。该模具有一个两端口通外的特殊型腔,一端是坯料形状,另一端是制件形状,两端之间的型腔是扫掠过渡轮廓。冲压时,拖动坯料使其从坯料口状端穿过型腔到制件状端口,沿途模具型腔的轮廓变化迫使坯料逐渐变成制件形状。通过拖料钢带拖动坯料。取制件时模具得停止活动。

Introduces the semifinished materials going through bending die,uses in the curved curving workpiece. Outside this mold has both sides to form the special die space ,one end is the semifinished materials shape,the other end is the workpiece shape,between the both sides die space is swept to get a changing cross-section gallery. When the die works ,the dragging semifinished materials cause it from the semifinished end traversing die space to the workpiece shape end,at the same time the die space outline change forces semifinished material gradually turning into the workpiece size along the way. The die movement will need to pause when the finished work-piece have to be taken out.
