钢模板是一种以钢代木的建筑施工器材,其半成品如图1所示。在钢模板制造过程中,为保证两侧面和两端头与底面的垂直度,需在轧角后切去两头。目前,生产钢模板单位一般采用铣头、锯头、磨头或用专用切头模具切头。我们在实践的基础上,设计制作了一套组合式切头模(图2),可对各种规格(本厂当时生产的规格有α=300、200、150、100mm 四 Steel template is a kind of steel construction equipment for steel, semi-finished products shown in Figure 1. In the steel plate manufacturing process, in order to ensure the two sides and the two ends and the bottom of the vertical, the need to cut off after the two corners. At present, the production of steel template unit generally used milling head, saw head, grinding head or cut with a special die head. On the basis of practice, we have designed and manufactured a set of modular cutting die (Figure 2), which can be used for all kinds of specifications (the specifications of our factory were α = 300,200,150,100mm
