Description

Technical Field

[0001] The utility model belongs to the technical field of electric welding machines, in particular to a two-protection electric welding machine. Background Art

[0002] The full name of CO2 shielded welding is CO2 gas shielded arc welding. The shielding gas is CO2 (sometimes a mixed gas of CO2+Ar), which is mainly used for manual welding. Since the shielding gas used is cheap, the weld is well formed when short-circuit transition is used, and the use of welding wire containing deoxidizer can obtain a quality welded joint without internal defects. Therefore, this welding method has become one of the most important welding methods for ferrous metal materials;

[0003] However, during the welding process, the carbon dioxide in the gas tank is often depleted, resulting in poor welding results. At the same time, carbon dioxide is colorless and odorless, so it is difficult for users to detect it. Therefore, we specially designed a two-protection electric welding machine.

[0037] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0038] Embodiment 1:

[0039] This embodiment provides a two-protection electric welding machine, including:

[0040] A housing 1, wherein a first mounting cavity 11 and a second mounting cavity 12 are provided in the housing 1, and a flip cover 2 is provided on a wall surface of the second mounting cavity 12;

[0041] The electric welding machine body 3 is arranged in the first installation cavity 11;

[0042] The gas supply device 4 is arranged in the second installation cavity 12, and the gas supply device 4 includes a gas supply tank 41, a transition gas tank 42 and an air pump 43. The gas supply tank 41, the transition gas tank 42 and the air pump 43 are arranged in sequence and connected together through an air pipe 44, and the air pipe 44 on the air pump 43 is connected to the electric welding machine body 3;

[0043] An air pressure sensor 5, which is arranged on the transition gas tank 42;

[0044] There are multiple gas supply tanks 41 , and the gas pipe 44 between the gas supply tank 41 and the transition gas tank 42 is connected with a solenoid valve 8 , which is used in conjunction with the air pressure sensor 5 .

[0045] It can be seen from this embodiment that a two-protection electric welding machine includes a housing 1, an electric welding machine body 3 and a gas supply device 4;

[0046] Two independent chambers are formed in the housing 1, which are respectively set as a first installation chamber 11 and a second installation chamber 12, and a flip cover 2 is formed on a side wall of the second installation chamber 12 away from the first installation chamber 11, so that the gas supply tank 41 can be replaced by opening and closing the flip cover 2;

[0047] The welding machine body 3 is installed in the first installation cavity 11, and the gas supply device 4 is installed in the second installation cavity 12. The housing 1 combines the welding machine body 3 and the gas supply device 4 together to form an integrated welding machine. The welding machine is purchased;

[0048] The gas supply device 4 includes a gas supply tank 41, a transition gas tank 42 and an air pump 43. The gas supply tank 41, the transition gas tank 42 and the air pump 43 are all connected with an air pipe 44, and the air pipe 44 at the air pump 43 is connected to the welding machine body 3, so as to achieve the function of gas supply protection. The air pipe 44 connecting the transition gas tank 42 and the gas supply tank 41 is connected to the electromagnetic valve 8. The gas supply tank 41 is a consumable. After the gas (carbon dioxide) in the tank is consumed, a new gas supply tank 41 can be replaced for use. The gas in the gas supply tank 41 flows into the transition gas tank 4 through the air pipe 44. 2 then flows from the transition gas tank 42 to the air pump 43, and under the action of the air pump 43, flows into the welding machine body 3, and a pressure sensor 5 is installed in the transition gas tank 42, and the pressure sensor 5 is connected to an alarm light 6, so that the gas pressure change in the transition gas tank 42 can be detected during the gas supply process, and an alarm is sounded when the gas pressure is too low. The pressure sensor 5 is connected to the circuit of the solenoid valve 8, and controls the opening and closing of the solenoid valve 8 according to the gas change. The air pump 43 transports the gas through the air pipe 44 connected to the transition gas tank 42 and the gas supply tank 41;

[0049] When in use, the solenoid valve 8 controls the gas flow between the multiple gas supply tanks 41 and the transition gas tank 42, and at the same time, only one of the solenoid valves 8 on the gas pipe 44 connecting the multiple gas supply tanks 41 and the transition gas tank 42 is in a normally open state, and the rest are in a normally closed state. When one of the multiple gas supply tanks 41 is insufficiently supplied with gas, resulting in insufficient air pressure in the transition gas tank 42, the air pressure detected by the air pressure sensor 5 becomes smaller, and one of the multiple solenoid valves 8 in the normally closed state is controlled to be normally opened, and the originally normally opened solenoid valve 8 is controlled to be normally closed, so that during the welding process, the gas is always sufficient, and the welding protection effect is good, and the welding effect is not poor due to insufficient gas supply. When the gas in the multiple gas supply tanks 41 is exhausted, resulting in insufficient air pressure in the transition gas tank 42, the air pressure sensor 5 will trigger the alarm to sound an alarm.

[0050] The multiple gas supply tanks 41 can effectively extend the use time, improve the use efficiency, and ensure the normal gas supply during the welding process, thereby improving the welding effect.
