Description

Technical Field

[0001] The utility model relates to the technical field of electric welding, in particular to an electric welding device which is easy to operate. Background Art

[0002] Electric welding is the common name for welding rod arc. It is a welding operation that uses welding rods to melt the metal parts that need to be connected through high temperature of electric arc. The basic working principle of electric welding is through the commonly used 220V voltage or 380V industrial electricity.

[0003] The basic working principle of electric welding is to use the commonly used 220V voltage or 380V industrial electricity, reduce the voltage through the pressure reducer in the electric welding machine, increase the current, and make the electricity generate huge arc heat to melt the welding rod and steel. The melting of the welding rod makes the fusion between steel higher.

[0004] The outer layer of the welding rod's coating and the CO2 gas ejected during CO2 welding prevent the metal from oxidizing after it melts (if you don't believe me, knock on the powder and see if it can weld). Of course, this explanation is a common one.

[0005] Arc welding is the most widely used welding method at present. It includes: manual arc welding, submerged arc welding, tungsten inert gas shielded arc welding, plasma arc welding, consumable electrode-gas shielded welding, etc.

[0006] Most arc welding uses the arc burning between the electrode and the workpiece as the heat source, and filler metal may or may not be used to form the joint.

[0007] When the electrode used is a welding wire that melts during the welding process, it is called consumable arc welding, such as manual arc welding, submerged arc welding, gas shielded arc welding, tubular wire arc welding, etc. When the electrode used is a carbon rod or tungsten rod that does not melt during the welding process, it is called infusible arc welding, such as tungsten inert gas arc welding, plasma arc welding, etc.

[0008] At present, conventional small electric welding machines are all transferred in the form of hand-held. When placed on the ground for use, if they need to be moved, they must be frequently picked up and put down, which is not convenient for small-scale transfer. At the same time, when welding, the welding gun part will produce smoke and powder slag during the welding process. The smoke will float directly upward and will be continuously inhaled by the workers. The powder slag will fall on the welding point, which will easily affect the welding effect. Utility Model Content

[0009] The purpose of the utility model is to solve the above-mentioned shortcomings in the prior art and to enable the welding machine to be transferred during use and to blow away the smoke and powder when the welding gun is welding an object.

The motor rotates at high speed, so that the blades can generate high-speed airflow, thereby blowing away the smoke and powder slag generated at the welding position. Blowing away the smoke can prevent workers from excessive inhalation, and blowing away the powder slag can improve the clarity of the welding position.

[0021] 2. Through the storage box structure, when the welding machine is carried, the welding gun, power lines and other detachable parts can be stored, which can be convenient for one-piece carrying.

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] Reference Figure 1-Figure 5A conveniently operated electric welding device comprises a base 1 arranged horizontally with the ground, a pair of symmetrical universal wheels 11 are distributed and fixed at the lower end of the base 1, a welding machine 12 is fixedly installed at the upper end of the base 1, a handle 13 for lifting is longitudinally mounted on the upper end face of the welding machine 12, a plurality of equidistantly distributed heat dissipation holes 14 are arranged at the lower end of the back of the welding machine 12, an electric connection head 15 is installed at the front of the welding machine 12, an end of the electric connection head 15 is electrically connected to a welding gun 17 through a transmission line 16, a handle 18 for hand-holding is fixed at the lower end of the outer wall of the welding gun 17, and a start switch 19 for energizing the welding gun 17 is installed on the outer wall of the handle 18.

[0030] It should be further explained that a cylinder 2 is fixed to the upper end of the outer wall of the welding gun 17 through a bracket, and the cylinder 2 and the welding gun 17 are arranged parallel to each other, which can ensure that the flow direction of the airflow of the welding gun 17 will not deviate too much when welding.

[0031] It should be further explained that a motor 21 is fixed to the inner wall of the cylinder 2 through a bracket, a driving shaft is assembled on the rotating shaft end of the motor 21 through a coupling, and blades 22 are fixed to the outer wall of the driving shaft with an arc length equal to the circumference. The motor 21 is a high-speed model and can increase the airflow intensity generated by the blades 22 through the effect of high-speed rotation.

[0032] It should be further explained that a battery 23 for powering the motor 21 is embedded in one end of the inner wall of the cylinder 2, and the battery 23 is a rechargeable lithium battery structure.

[0033] It should be further explained that two pillars of equal specifications are distributed on one side of the upper end surface of the base 1, and the upper ends of the two pillars are jointly supported and installed with the same storage box 3. The inner wall of the storage box 3 is embedded with a partition 31 for dividing the space, which can be received during the welding work of the welding machine 12, and accessories such as the welding gun 17 and the transmission line 16 can be centrally stored and carried in an integrated manner.

[0034] It should be further explained that the storage box 3 is provided with a cover 32 covering its internal space. The cover 32 is made of a transparent high-strength plastic material. A limit strip 33 is fixed to the lower end of the inner wall surface of the cover 32. The limit strip 33 is slidingly and tightly set against the lower end surface of the inner wall of the storage box 3, so that the situation inside the storage box 3 can be peeped into to determine whether there is anything missed when carrying it.

[0035] It should be further explained that a connecting plate 4 is installed in the middle position of the upper end of the cover plate 32, a threaded rod 41 is fixed at the center position of one side of the connecting plate 4, and a ring 42 for sliding docking and positioning with the threaded rod 41 is fixed to the upper end of the storage box 3 through a bracket. By positioning the cover plate 32 and the upper end of the storage box 3, the coverage stability of the cover plate 32 and the storage box 3 can be ensured.

[0036] It should be further explained that a nut 43 is threadedly connected to the outer wall of the threaded rod 41, and one end face of the nut 43 is tightly pressed against the end face of the ring 42. The outer ring of the nut 43 is a hexagonal structure and is symmetrically welded with a knob 44. The mutual threaded connection between the nut 43 and the threaded rod 41 can ensure the stable coverage of the cover 32 and the storage box 3. The limit strip 33 of the cover 32 can contact the inner wall surface of the storage box 3, thereby realizing sliding limit and ensuring that the cover 32 is fixed in position after installation.

[0037] Working method: When welding of objects is required, the whole structure can be carried to the designated position through the handle 13 and placed on the ground. When adjusting the position, it can be moved to any position directly through the universal wheel 11. The model of the universal wheel 11 is the DW series, which has a built-in braking function and can be braked and positioned when moved to the designated position.

[0038] Then, the power transmission line 16 connected to the tail of the welding gun 17 is energized and connected to the power connector 15, so that the welding gun 17 can pass normally. The worker holds the handle 18 and presses the start switch 19 with his fingers, so that the welding gun 17 can perform welding work at the welding position. During welding, the power supply of the battery 23 can be turned on. The battery 23 provides power for the motor 21. The shaft of the motor 21 rotates at a high speed with the blades 22 on the drive shaft, thereby generating a high-speed airflow, thereby dispersing smoke and powder slag at the welding position, and preventing the workers and welding points from inhaling excessive smoke and preventing powder slag from gathering at the welding points to affect the welding quality.

[0039] After the overall welding work is completed, the power transmission line 16 is removed and the welding gun 17 is stored. At this time, the nut 43 is turned by the knob 44 to separate it from the threaded rod 41 by thread. The threaded rod 41 and the ring 42 are slidably disengaged from each other, so that the cover 32 and the storage box 3 can be separated, and then the welding gun 17 and accessories such as the power transmission line 16 can be placed in the storage box 3, and they can be placed in layers through the partition 31.

[0040] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
