我厂在生产中遇到了一需要进行收口加工的产品(图1)。其中1为本体,经塑料压注成型。为避免该产品头部损坏和防潮,在头部增加了防潮膜2和保护罩3。防潮膜用紫铜片制成,厚约0.1mm;保护罩为钢带经冲压而成,厚约0.2～0.3mm。该产品要求序号1、2、3经辊压后成为一整体。为避免损坏工件表面,预防毛刺的产生,我们设计了机夹收口辊刀。由于该辊刀在工作中需承受较大的接触压 I encountered in the production of a factory need to shut down the processing of products (Figure 1). One of the body, the plastic pressure injection molding. In order to avoid the product head damage and moisture-proof, moisture-proof membrane 2 and protective cover 3 are added to the head. Moisture-proof film made of copper, thickness of about 0.1mm; protective cover made of steel by stamping, thickness of about 0.2 ~ 0.3mm. The product requires serial numbers 1, 2 and 3 to be integrated as rolled. In order to avoid damage to the workpiece surface, to prevent the generation of burrs, we designed the folder clip roller knife. As the roller knife in work to withstand greater contact pressure
