我們都知道拉伸是主要的沖壓工序之一，其應(yīng)用***。用拉伸工藝可以制成圓筒形、矩形、階梯形、球形、錐形、拋物線形及其他不規(guī)則形狀的薄壁零件。接下來(lái)，小編就為您介紹下五金沖壓拉伸成型加工工藝。 </p> <p> <br /> </p> <p> 1、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(duì)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(kuò)形加工。 </p> <p> <br /> </p> <p> 2、再拉伸加工：即對(duì)一次拉伸加工無(wú)法完成的深拉伸產(chǎn)品，需要將拉伸加工的成形產(chǎn)品進(jìn)行再次拉伸，以增加成形容器的深度。 </p> <p> <br /> </p> <p> <br /> 深圳防腐精密拉伸五金件加工聚氨酯涂層是一種為適應(yīng)環(huán)保需求而研制開(kāi)發(fā)的一種新型綠色特殊涂層，有良好的耐磨和耐腐蝕性。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;"
