EXOTHERMIC WELDING CUP AND EXOTHERMIC WELDING CAPSULE - SUNLIGHT CHENGDU XIHANGGANG ELECTRIC MFG CO LTD

Title:

EXOTHERMIC WELDING CUP AND EXOTHERMIC WELDING CAPSULE

Document Type and Number:

WIPO Patent Application WO/2019/137124

Kind Code:

A1

Abstract:

An exothermic welding cup and an exothermic welding capsule, belonging to the field of exothermic welding tools, wherein the exothermic welding cup (010) comprises a cup body (100), a cover body (200) and an igniter (300); the cup body (100) is used for accommodating welding powder, the cup body (100) has an opening (110), and the cover body (200) is used for covering the opening (110); the igniter (300) comprises a heat generating portion (310); the heat generating portion (310) is disposed inside of the cup body (100), and the heat generating portion (310) comprises an insulating member (313) and a heat generating member (311); the insulating member (313) is disposed between the heat generating member (311) and the cover body (200). Short circuiting due to a heat generating member touching a cover body when generating heat may be avoided by means of the exothermic welding cup. In addition, a encapsulation ring (210) is also provided between the cover body (200) and the cup body (100) for encapsulation; the powder may be prevented from falling out by means of the encapsulation ring encapsulating the welding powder within the cup body; moreover, in an actual welding process, the encapsulation ring made from stainless steel does not fail easily, and may ensure that the welding powder within the cup body may also be effectively encapsulated within a certain welding time.
