Description

Technical Field

[0001] The present application relates to the field of welding technology, and more specifically, to a smoke protection structure for sheet metal welding. Background Art

[0002] Welding is an important material processing technology. The definition of welding is as follows: the process of heating or pressurizing the materials of the workpieces to achieve atomic bonding to form a permanent connection is called welding. During welding, a protective structure will be set up to prevent the spread of welding slag and smoke.

[0003] In the related art, it is pointed out that the welding slag generated during the welding process can easily cause burns to the surrounding users, reduce the safety of the use of welding equipment, and pose a great safety hazard. The patent with the prior art publication number CN215747475U provides a steel structure welding protection device. The device is provided with a splash-proof mechanism. The splash-proof protection mechanism is arranged on the workbench body. The splash-proof protection mechanism includes a side plate, which protects a place close to the welding equipment to reduce the splash of welding slag and facilitate the rotation welding of the welding equipment. A support frame is connected to the side plate to play a connecting role and fix the transparent baffle. A transparent baffle is arranged in the support frame to prevent the splash of welding slag and the strong light generated during welding from irritating the user's eyes.

[0004] Although the splash-proof mechanism and the transparent baffle in the above-mentioned prior art solution can prevent the splashing of welding slag and the irritation of the user's eyes to the strong light generated during welding, it still has the following defects: the device cannot protect against smoke, and a large amount of smoke will be generated during welding. The smoke will spread rapidly, affecting the staff's line of sight and making it impossible to accurately observe the welding progress.

[0005] In view of this, we propose a smoke protection structure for sheet metal welding. Utility Model Content

The smoke concentration detector 106 can detect the smoke concentration inside the protection box 1, and the suction mechanism 3 is turned on during welding. If the smoke concentration value is high in one place, the electric slide rail 105 drives the sliding frame 2042 to drive the smoke conveying pipe group 2, the suction mechanism 3 and the cleaning component 4 to move to a position with higher concentration, so as to better extract the smoke, and the telescopic tube 202 in the smoke conveying pipe group 2 facilitates the movement of the suction mechanism 3 and the cleaning component 4, and the suction machine is started when extracting smoke.
