Technical Field

[0001] The utility model relates to the technical field of welding equipment, in particular to a carbon dioxide shielded welding machine that is resistant to wind interference. Background Art

[0002] CO2 shielded arc welding (CO2-shielded arc welding) uses CO2 (sometimes a mixture of CO2 and Ar) as the shielding gas, primarily for manual welding. Due to the low cost of the shielding gas, the excellent weld formation achieved with short-circuit welding, and the use of deoxidizing wire, high-quality welds free of internal defects, this welding method has become one of the most important for ferrous metals.

[0003] During the welding process of the carbon dioxide shielded welding machine, the carbon dioxide shielding gas used to cover the welding area needs to be maintained at a certain concentration to prevent the shielding gas from mixing with a large amount of air. Therefore, attention should be paid to wind protection to avoid air convection caused by wind, which will lead to a decrease in the shielding gas concentration and have an adverse effect on the welding effect.

[0004] Therefore, in view of the problem that the shielding gas released by the existing carbon dioxide shielded welding machine during welding is easily blown away by the wind, a carbon dioxide shielded welding machine that can prevent wind interference and solve the above problem is needed.

[0030] Example 1:

[0031] Reference Figure 1-5 , a wind-interference-proof carbon dioxide shielded welding machine, comprising a protective shell 1, a placement cavity is provided inside the protective shell 1, a welding machine body 4 is installed on the bottom side of the inner wall of the placement cavity, a gas tank 5 is installed on the left side of the inner wall of the placement cavity, an electric valve 6 is installed on the output end of the gas tank 5, a cover body 3 is provided on the front side of the protective shell 1, a hinge 2 is connected between the protective shell 1 and the cover body 3, a locking sleeve is installed on the outer wall of the cover body 3, a storage sleeve 8 is fixedly connected to the left and right sides of the protective shell 1, the interior of the storage sleeve 8 is connected to a windshield 9 through a sliding component 1, and the interior of the windshield 9 is connected to a windshield 2 10 through a sliding component 2; one end of the hinge 2 is fixedly connected to the front end of the top side of the protective shell 1, and the other end of the hinge 2 is fixedly connected to the top side of the cover body 3; universal wheels 7 are installed at the four corners of the bottom side of the protective shell 1 through wheel frames;

[0032] Specifically, the protective housing 1 protects the welder body 4, gas tank 5, and electric valve 6 within. The gas tank 5 contains compressed carbon dioxide shielding gas. The input of the electric valve 6 is connected to the output of the gas tank 5, and the output of the electric valve 6 is connected to the gas pipe that delivers the gas. The lid 3 can be opened and closed via a hinge 2 at the top. By opening the lid 3, the gas tank 5 can be replaced, the pipeline to the electric valve 6 can be connected, and the wiring to the welder body 4 can be connected.

[0033] Sliding assembly 1 includes sliding cavity 1, which is opened inside the storage sleeve 8. Sliding member 11 is slidably connected to the interior of sliding cavity 1. The front side of sliding member 11 is connected to the rear side of windshield 1 9 via damping shaft 1. Sliding assembly 2 includes sliding cavity 2, which is opened inside the windshield 1 9. Sliding member 2 is slidably connected to the interior of sliding cavity 2. The front side of sliding member 2 12 is connected to the rear side of windshield 1 9 via damping shaft 2. The size of windshield 1 9 is smaller than that of storage sleeve 8, and the size of windshield 2 10 is smaller than that of windshield 1 9.

[0034] Specifically, when welding, wind can disperse the shielding gas released for welding, thereby reducing the concentration of the shielding gas and affecting welding. Therefore, before welding, windshield 1 (9) is pulled to cause sliding member 1 (11) connected via damping shaft 1 to slide within sliding cavity 1, thereby pulling out windshield 1 (9). Subsequently, windshield 2 (10) is pulled to cause sliding member 2 (12) connected via damping shaft 2 to slide within sliding cavity 2, thereby pulling out windshield 2 (10). Finally, force is applied to windshield 1 (9) and windshield 2 (10), causing them to rotate via damping shaft 1 and damping shaft 2, thereby changing the posture and angle of windshield 1 (9) and windshield 2 (10). This blocks the wind and prevents it from dispersing the carbon dioxide shielding gas used to assist welding, thereby improving welding quality.

[0035] Example 2:

[0036] The locking sleeve includes multiple inner sleeves 13, the outer walls of which are fixedly connected to the interior of the protective shell 1. The rear end of the cover body 3 is provided with multiple notches, which divide the rear end of the cover body 3 into multiple clamping parts. The outer walls of the clamping parts are provided with threads 14. The rear end of the cover body 3 is threadedly connected to a fixing sleeve 15 through the threads 14. The front end of the inner sleeve 13 is fixedly connected to a rubber ring 16.

[0037] Specifically, the notch is offset toward the periphery with the center of the inner sleeve 13 as a reference point, and the inner sleeve 13 as a whole has a certain degree of elasticity. The interior of the inner sleeve 13 is used to sheath a cable or air pipe. Before connecting the air pipe to the electric valve 6 and before connecting the cable to the welding body 4, the fixing sleeve 15 is removed from the rear end of the inner sleeve 13 by rotation. The cable or air pipe is then passed through the fixing sleeve 15 and the inner sleeve 13 in sequence. After passing through the front end of the inner sleeve 13, the rubber ring 16 wraps and secures the outer wall of the cable or air pipe and protects the connection. The fixing sleeve 15 is then installed on the clamping portion at the rear end of the inner sleeve 13 by rotation. During the installation process of the fixing sleeve 15, the fixing sleeve 15 applies force to the offset clamping portion, causing the clamping portion to close toward the center and clamp the cable or air pipe in the inner sleeve 13. This prevents the cable or air pipe from easily falling off the electric valve 6 or the welding body when pulled from the outside, thereby increasing the firmness of the cable or air pipe.

[0038] Working principle: Before connecting the air pipe to the electric valve 6 and before connecting the cable to the welding body 4, the fixing sleeve 15 is removed from the rear end of the inner sleeve 13 by rotating, and then the cable or air pipe is passed through the fixing sleeve 15 and the inner sleeve 13 in turn. After passing through the front end of the inner sleeve 13, the rubber ring 16 will wrap and fix the outer wall of the cable or air pipe and protect the connection. Then the fixing sleeve 15 is installed on the clamping part at the rear end of the inner sleeve 13 by rotating. During the installation process of the fixing sleeve 15, the fixing sleeve 15 applies force to the offset clamping part to close the clamping part toward the center and clamp and fix the cable or air pipe in the inner sleeve 13, so that the cable or air pipe will not easily fall off from the electric valve 6 or the welding machine body when pulled from the outside, thereby increasing the firmness of the cable or air pipe. By pulling the windshield 19, the sliding member 11 connected by the damping shaft 1 slides in the sliding cavity 1, thereby pulling the windshield 19 out. Then, by pulling the windshield 2 10, the sliding member 2 12 connected by the damping shaft 2 slides in the sliding cavity 2, thereby pulling the windshield 2 10 out. Then, force is applied to the windshield 19 and the windshield 2 10 to rotate through the damping shaft 1 and the damping shaft 2, thereby changing the posture and angle of the windshield 19 and the windshield 2 10, so as to block the wind and prevent the wind from blowing away the carbon dioxide shielding gas used for auxiliary welding, thereby improving the quality of welding.

[0039] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
