开式压力机是一种通用性压力机,被广泛适用于冲孔、落料、切边、弯曲、浅拉伸和成形等冷冲压工序。同时,由于开式压力机具有开式机身,其突出的优点是:工作台在三个方向是敞开的,装、卸模具和操作都比较方便,为设备自动化和机械化提供了良好的条件,因此,开式压力机得到了广泛的应用,仅上海仪表局系统,就拥有开式压力 Open press is a universal press that is widely used in cold stamping processes such as punching, blanking, trimming, bending, shallow drawing and forming. At the same time, as the open press has an open body, its outstanding advantages are: table is open in three directions, loading and unloading molds and operations are more convenient for equipment automation and mechanization provided a good condition, Therefore, the open press has been widely used, only Shanghai Instrument Bureau system, it has open pressure
