凸模的固定安裝方式

凸模的安裝是在凸模固定板上進(jìn)行的，有定位與固定兩方面的要求。凸模定位是通過凸模與固定板上孔的配合來實現(xiàn)，固定可通過掛肩、螺栓、鉚接、環(huán)氧樹脂膠、側(cè)銷、橫銷和壓板等完成。直通型凸模由于外形不規(guī)則，所以需要在安裝部位加設(shè)一個長方體的凸模鑲件進(jìn)行輔助。

固定板固定凸模位置與凸模刃口工作位置有距離，易使凸模失穩(wěn)造成失效，如果凸模刃口尺寸較小，根本不可能正常量產(chǎn)。凸模做成壓板固定時加設(shè)一個卸料鑲件，凸模穿過卸料鑲件與凹模進(jìn)行沖裁時，卸料鑲件可以引導(dǎo)凸模進(jìn)入凹模，保護(hù)凸模免受側(cè)向力。

該凸模與卸料鑲件的單邊間隙設(shè)計成0.003～0.005mm甚至更小，凸模工作時露出卸料鑲件3mm左右，不易受到損害。凸模安裝部位尺寸設(shè)計成與固定板方孔尺寸一致或者略小一點，壓板槽比固定板低0.02～0.05mm，讓凸模在固定板里有一點活動余地，真正定位依靠卸料鑲件，避免固定板與卸料鑲件二者定位產(chǎn)生相互干涉。

由于卸料鑲件定位處就是凸模刃口工作位置，因此效果佳。卸下壓板螺釘，拔出壓板就可以取出凸模，凸模拆卸方便，能實現(xiàn)凸模的快速保養(yǎng)與維修。
