一种一次性气瓶用爆破片制造方法
摘要：
一种一次性气瓶用爆破片制造方法属于安全装备技术领域,涉及到流体压力的安全泄压装置,特别适用于一次性气瓶用爆破片的制造方法。本发明是将平坯片压制成形,在成形后的爆破片坯片上利用带有非闭合环形刀刃的刀具压制环形减弱槽,非闭合环槽的两端自然形成钝化角止裂结构,槽两端与爆破片中心连线的夹角介于30°～60°之间,压槽刀具两刃面间的夹角为15°～90°。本发明能满足一次性气瓶用爆破片的各项性能要求,具有效率高,成本低,质量稳定等优点,可广泛应用于化工、石油化工、石油炼制、化学、电力、冶金、运输等行业中流体压力系统的安全泄压装置的各种爆破片的制造,特别适合于批量生产。
摘要（英）：

The present invention belongs to the field of safety equipment technology and relates to the manufacture of safe liquid pressure releaser, especially once used rupture disk for gas cylinder. After plate is pressed into blank of the rupture disk, the blank is further pressed with a non-closed tool to form a non-closed annular weakening groove in angular aperture of 30-60 deg and with naturally formed dull crack-stopping structure in two ends. The present invention has the advantages of high efficiency, low cost, stable quality, etc. and may be used in manufacture of various rupture disk for different pressure releaser.
