</p> <p> </p> <p> 造成表面劃痕的因素有：不銹鋼拉伸件的表面會出現(xiàn)劃痕是由于工件與模具表面存在相對的移動，在一定的壓力促使下，導(dǎo)致坯料和模具局部表面直接產(chǎn)生摩擦，加之坯料的變形熱使得坯料和金屑熔蓋在模具的表面上，惠州沖壓精密拉伸五金件哪里好，使工件外表擦傷產(chǎn)生劃痕。 </p> <p> <br />

拉伸加工：使用壓板裝置，利用凸模的沖壓力，將平板材的一部分或者全部拉入凹模型腔內(nèi)，使之成形為帶底的容器。容器的側(cè)壁與拉伸方向平行的加工，是單純的拉伸加工，而對圓錐（或角錐）形容器、半球形容器及拋物線面容器等的拉伸加工，其中還包含擴形加工。 </p> <p> <br /> </p> <p> 再拉伸加工：即對一次拉伸加工無法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> 逆向拉伸加工：將前工序的拉伸工件進行反向拉伸，工件內(nèi)側(cè)變成外側(cè)，并使其外徑變小的加工。 </p> <p> <br /> </p> <p>
