本发明涉及金属板加工技术领域，特别涉及一种用于易拉罐的金属板材加工工艺，设置的定位单元，通过侧边校直组件相向移动对板材进行居中校直，弹性下压组件使得板材在无推力作用的情况下，能够静止贴合在配合孔板上端，尽可能地减小冲压造成的板材变形；设置的冲裁单元，在液压件推动定位套筒下移的过程中，通过弹簧二使得滑动压环能够弹性地对板材进行定位压紧，紧接着旋切组件会在板材上压出凹痕，然后旋切组件进行旋转切割出圆片，先通过冲压可使片材部分先断开，减小应力，防止变形，后旋转切割可将剩余部分裁切完成，加工出完整的圆形罐盖，通过顶出组件能够将切出的圆形罐盖向下轻轻顶落，有利于冲裁后罐盖的快速脱落，提高整体效率。 The invention relates to the technical field of metal plate processing, in particular to a metal plate processing technology for a zip-top can, a positioning unit is arranged, a plate is centered and straightened through opposite movement of side edge straightening assemblies, and an elastic pressing assembly enables the plate to be statically attached to the upper end of a matched pore plate under the condition of no thrust action, so that the plate can be firmly fixed, and the plate can be firmly fixed. Plate deformation caused by stamping is reduced as much as possible; according to the arranged blanking unit, in the process that a hydraulic part pushes a positioning sleeve to move downwards, a sliding pressing ri
