过去我们每冲制一种规格的垫圈就需要更换一整套模具,这样不仅增加了设计和制作的工作量,而且还浪费了不少钢材,为此,我们力求在同类系列产品的范畴内使模具的共用性达到较高的程度,设计了系列垫圈冲模(见图)。该模具制造简单,同轴度好,它既可单独进行一种规格垫圈的冲制,又可同时进行材料厚度相同的几种规格的垫圈冲制, In the past, we needed to change a set of molds for each type of washer. This not only increased the workload of design and manufacture, but also wasted a lot of steel. To this end, we tried to make molds in the same series of products To achieve a higher degree of commonality, designed a series of washers die (see photo). The mold is simple to manufacture and has good concentricity. The utility model can be used for stamping of a kind of washers in a single type, and forging of several kinds of washers of the same material thickness at the same time,
