Description

Technical Field

[0001] This utility model relates to the field of welding wire production technology, and in particular to an air blowing device that facilitates increasing air pressure in the production of aluminum and aluminum alloy welding wires. Background Technology

[0002] Gas shielded welding refers to a welding method protected by carbon dioxide or argon gas. It does not use welding rods but welding wire, and has high welding efficiency. Argon shielded welding is mainly used to weld materials such as aluminum, titanium, and stainless steel. In the production process of welding wire, air blowing devices are used, for example, in the copper plating process of welding wire and the ultrasonic water washing or pickling process of aluminum alloy welding wire. It is used to clean the residual liquid on the surface of the wire, so that the wire does not need to be cleaned with water or requires little water.

[0003] However, current air blowing devices are usually bidirectional, which leads to the negative effect of reduced air pressure and reduced cleaning effectiveness. Furthermore, when existing wires pass through the air blowing device, the lack of a wire guiding function causes the wires to come into contact with and rub against the air blowing device, which in turn wears down the wires. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an air-blowing device that facilitates increasing air pressure during the production of aluminum and aluminum alloy welding wire.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An air blowing device for increasing air pressure in the production of aluminum and aluminum alloy welding wire includes a base plate. A device housing is fixedly connected to the upper end of the base plate. Two conduits communicating with the interior of the device housing are fixedly connected to the left and right side walls of the device housing. Each conduit has an inlet mechanism and an outlet mechanism. The inlet mechanism includes an inlet connector threaded onto the conduit, with a conical hole inside. The outlet mechanism includes an outlet connector threaded onto the conduit, with a cylindrical hole inside. The diameter of the smaller end of the conical hole is 1 mm larger than the diameter of the cylindrical hole. The inner walls of both the conical and cylindrical holes are coated with tungsten carbide. Guide mechanisms are provided on both the left and right sides of the upper end of the device housing, and an air supply mechanism is located between the two guide mechanisms at the upper end of the device housing.

[0007] As a further improvement of this utility model, a first hexagonal sleeve block is fixedly sleeved on the outer side wall of the inlet connector.

[0008] As a further improvement of this utility model, a second hexagonal sleeve block is fixedly sleeved on the outer side wall of the cable outlet connector.

[0009] As a further improvement of this utility model, the guiding mechanism includes an L-shaped frame, with two connecting bolts running through the horizontal part of the L-shaped frame. The two connecting bolts are screwed onto the upper end of the device housing. Two guide wheels are embedded in the vertical part of the L-shaped frame, and the guide wheels are rotatably connected to the L-shaped frame.

[0010] As a further improvement of this utility model, the air supply mechanism includes an air inlet connector fixedly connected to the top of the device housing, the upper end of the air inlet connector being threaded with a connecting nut, and the upper end of the connecting nut being fixedly connected with an air supply pipe.

[0011] As a further improvement of this utility model, two mounting bolts are provided through the upper end of the base plate, and the two mounting bolts are symmetrically arranged on both sides of the device shell.

[0012] The beneficial effects of this utility model are:

[0013] Because the diameter of the small end of the conical hole is larger than that of the cylindrical hole by mm, the gas inside the device housing can be discharged through the inlet connector, which can make the air blowing direction reach one direction, thereby increasing the air pressure inside the air blowing device, thus achieving the effect of quickly cleaning the liquid on the surface of the wire.

[0014] The guiding mechanism can guide the wire to avoid skew, allowing the wire to pass through the air blowing device more stably and preventing the wire from contacting and rubbing against the air blowing device. Furthermore, the inner walls of the conical and cylindrical holes are coated with tungsten carbide to prevent the wire from being abraded when entering the device. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-5 A pneumatic blowing device for increasing air pressure in the production of aluminum and aluminum alloy welding wire includes a base plate 1. A device housing 2 is fixedly connected to the upper end of the base plate 1. Two mounting bolts 3 are symmetrically arranged on both sides of the device housing 2 through the upper end of the base plate 1, allowing the base plate 1 to be installed. A conduit 11 communicating with the interior of the device housing 2 is fixedly connected to both the left and right side walls of the device housing 2. The two conduits 11 are respectively equipped with an inlet mechanism and an outlet mechanism. The inlet mechanism includes an inlet connector 10 threaded onto the conduit 11, and the inlet connector 10 has a conical interior. The conical hole 15 and the cable outlet mechanism include a cable outlet connector 14 threaded onto the cable conduit 11. The cable outlet connector 14 has a cylindrical hole 16 inside. The diameter of the small end of the conical hole 15 is 1 mm larger than the diameter of the cylindrical hole 16. The inner walls of the conical hole 15 and the cylindrical hole 16 are coated with tungsten carbide. A first hexagonal sleeve block 12 is fixedly sleeved on the outer wall of the cable inlet connector 10, and a second hexagonal sleeve block 13 is fixedly sleeved on the outer wall of the cable outlet connector 14. The upper left and right sides of the device housing 2 are provided with guide mechanisms, and the upper end of the device housing 2 is provided with an air supply mechanism located between the two guide mechanisms.

[0023] In this utility model, the guiding mechanism includes an L-shaped frame 7. Two connecting bolts 8 are provided through the horizontal part of the L-shaped frame 7. The two connecting bolts 8 are screwed to the upper end of the device housing 2. Two guide wheels 9 are embedded in the vertical part of the L-shaped frame 7. The guide wheels 9 are rotatably connected to the L-shaped frame 7. When the wire is passed between the guide wheels 9, the wire can be guided to avoid the wire from being skewed.

[0024] The air supply mechanism includes an air inlet connector 4 fixedly connected to the top of the device housing 2. A connecting nut 5 is threaded onto the upper end of the air inlet connector 4. An air supply pipe 6 is fixedly connected to the upper end of the connecting nut 5. An existing air compressor is connected to the air supply pipe 6.

[0025] When this utility model is in use, the wire is passed through the guide wheels 9, which guides the wire and prevents it from being skewed. This allows the wire to pass through the air blowing device more stably, avoiding contact and friction between the wire and the air blowing device. This prevents the wire from being worn when entering the device. The wire enters from the inlet connector 10 and exits from the outlet connector 14. Air is supplied to the inside of the device housing 2 through the air supply pipe 6. Since the diameter of the small end of the conical hole 15 is 1mm larger than the diameter of the cylindrical hole 16, the gas inside the device housing 2 is discharged through the inlet connector 10. This allows the air to blow in one direction, thereby increasing the air pressure inside the air blowing device and achieving the effect of quickly cleaning the liquid on the surface of the wire.

[0026] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
