我厂小五金零件——横梁的弯曲模中有左、中,右三凸模(图1),其工作部分用于同时弯曲横梁的内形(图2),故有严格的相关位置的要求。具体要求是: 1.装配后工作时左、中、右三只凸模的R160.8弧面必须是同一圆弧面(图3)。 2.装配后工作时三只凸模两斜面上各对应点○—○等的厚度必须一致和等高。 3.装配后工作时三只凸模的中心线N—N必须在同一中心线上。 I plant hardware parts - beam bending mold left, right and left three punch (Figure 1), the working part of the beam used to simultaneously bend the shape (Figure 2), so there are strict requirements of the relevant locations. Specific requirements are: 1. After assembly work left, center and right punch R160.8 arc surface must be the same arc surface (Figure 3). 2. After assembly work three punch two bevel on the corresponding point ○ - ○ thickness must be the same and contour. 3. The centerline N-N of the three punches must be on the same centerline when working after assembly.
