燃料混合管压形缩管模陕西科技大学(陕西咸阳 712081) 刘俊生 周明贵 张喜涛[摘要] 介绍了一种在机械压力机上实现较长尺寸缩管工件的成形模结构。关键词 闭合高度 缩管 脱模1 引言管材的缩管是常见的成形工艺，常用3种方法：1在缩管旋转机上进行；2在车床上旋压缩口，滚压加工；3用模具在压力机上进行。具体使用哪种方法，视工件要求而定。针对图1所示零件，采用压力机成形工艺比较合适。 根据零件尺寸，材料及计算结果，若在螺旋压力机或液压机上成形，由于工件成形所需压力很小，不能充分利用设备功率，且生产效率较低。故而选用机械压力机成形，模具设计中应重点解决由于工件缩管长度较长而引起的脱模困难，同时又要兼顾模具的闭合高度(在成形很小的情况下，模具闭合高度成为选用机床的主要因素)。2 模具结构 模具结构如图2所示。上内凹模2直接装在模柄上，夹持于滑块中，利用滑块中的打杆槽，装有上拉料黠构，上拉料结构由打料杆14，拉杆13，拉板12，螺栓8，顶杆10组成。下模板固定于工作台面，顶板9位于台面漏料孔中。其特点是：(1)利用冲床，滑块在缩门成形工序完成后拉动打料杆14，使与之连成一体顶杆10向上抬起，解决了由于工件缩口长度较长而引起的脱模困难。(2)顶板9置于工作台漏料孔中，即有效利用机床闭合高度，又减少于模具体积。3工作过程 冲床滑块上升至上死点时，穿在滑块上的打料杆14带动上拉料组件以至最高点。放管材于定位板4的定位孔中。滑块下行，定位销3导正管材上端进入上凹模2定位孔中后，滑块施轴向力于管材端面．通过模芯11进行缩口，最后通过定位板4与上内凹模进行凸台压形，模芯11和上凹模2材料选用W18Cr4v，热处理硬度61—63HRC。同时，上拉料组件也随滑块一起下降之下死点，压形，缩口完成后，随着滑块一起上升的上拉料组件中的顶杆10抬起工件，取出工件。4 效果该模具装于400kN偏心冲床（闭合高度300mm，工作台孔直径∮200mm）上，经过近十万件产品的生产，模具基本完好，满足了生产的要求。
