Description

Technical Field

[0001] The utility model relates to the technical field of sheet metal welding processing, in particular to an elastic curtain blocking device for sheet metal welding equipment. Background Art

[0002] Arc welding generates arc radiation including infrared, visible light and ultraviolet rays, which can damage human eyes and skin. Therefore, workers need to wear protective shields during processing. With the advancement of technology, existing welding has the conditions for automated welding. Therefore, machines are used instead of manual welding to effectively avoid the harm of arc to workers. However, during the welding process, arc still has a certain impact on the surrounding environment. If workers are not careful when passing by the welding station, they may be radiated by arc. Therefore, curtains are needed to isolate the welding station to prevent arc radiation.

[0003] For example, the Chinese patent application number CN201910146838.4, with an announcement date of 2019.05.21, discloses an automatic folding rotating welding smoke control hood, which can block smoke, prevent smoke from overflowing, and shield the welding arc.

[0004] However, the arc-shaped curtain in the document is fixedly connected to the rotating arm. Therefore, in actual application, if the curtain is hit during welding, it is easy to cause the entire curtain to be knocked down due to rigid collision, or cause damage to the connection between the curtain and the rotating arm.
