Abstract
Description
Technical Field
[0001] This utility model belongs to the field of welding technology, specifically relating to welding machines and their wire feeders. Background Technology
[0002] The wire feeding process of a welding machine usually requires a wire feeder. The control cable of the wire feeder must be correctly connected to the welding machine, including the gas hose, the red plug of the welding cable (usually connected to the negative output terminal of the welding machine), and the remote control plug (connected to the 14-pin socket of the welding machine). For example, when the welding flame is sprayed, the internal motor of the wire feeder is activated, feeding the welding wire at a constant speed.
[0003] To improve welding efficiency, the use of a wire feeder can save the traditional manual wire feeding steps and increase welding speed by 1 to 2 times. The wire feeder pre-coils the welding wire in a circular box, pulls out one end, and uses a motor to deliver it along the outer sheath. This is especially useful for oil pipelines located in the field, where the ground is muddy after rain; the outer sheath can help keep the mud and water out of the mud.
[0004] When the wire feeder delivers the welding wire, it uses a motor to power the wire feeder to move the wire through the outer sheath. The cable length of the welding machine is generally more than 2m, and the corresponding length of the outer sheath is also not less than 2m. This causes the outer sheath and the welding wire inside to often fall to the ground, making them easy for on-site personnel to step on, which is not conducive to the safety of the welding wire inside the outer sheath. Therefore, we propose a welding machine and its wire feeder. Utility Model Content
[0005] The purpose of this invention is to provide a welding machine and its welding wire feeder, which can suspend the outer sheath tube and the welding wire inside, minimizing the portion of the outer sheath tube that is stepped on when it falls to the ground, thereby improving the safety of the welding wire inside the outer sheath tube.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A welding machine includes a chassis with an exhaust port on the front. A welding torch is mounted on the exhaust port. The welding torch includes a protective sleeve and an electrode fork installed in the middle of the protective sleeve. During operation, the chassis provides a high-voltage power supply to the welding torch, causing the electrode fork to emit a high-temperature arc to melt the welding wire. Argon gas from the chassis's gas tank is ejected from the welding torch through a pipe. The argon gas acts as a shielding gas, spraying around the welding wire to isolate the molten droplets and molten pool from the air, preventing oxidation and contamination of the molten pool, thus ensuring the quality of the weld joint. At the same time, the flow of the shielding gas can also stabilize the welding arc, preventing violent oscillations and instability of the arc during the welding process.
[0008] Wire feeding device, including distribution box, the back of the distribution box is communicated and fixed with wire box, the wire box is hollow disc-shaped with one side opening, and the hollow area of the disc-shaped wire box is provided with a wire feeding mechanism, the upper surface of the distribution box is rotatably installed with a rotating shaft, the upper end of the rotating shaft is bifurcated in a Y shape, a plurality of threaded pipes are horizontally arrayed above the distribution box, one end of each threaded pipe is a screw head structure, and the inner edge of the other end is an internal thread structure matched with the screw head, the other end of one of the threaded pipes is further rotatably connected to the inside of the bifurcated structure of the rotating shaft, and the lower surface of each threaded pipe is fixed with a cantilever, the end of the cantilever away from the threaded pipe is rotatably installed with a support wheel, when welding outdoors, the welding wire is wound and put into the wire box in advance, the head is pulled out and passes through the wire feeding mechanism of the distribution box, and is sent to the welding gun along the outer sheath pipe. With the power-on of the welding gun, the wire feeding mechanism operates synchronously and uniformly feeds the welding wire. Since the welder continuously advances along the welding area, the outer sheath pipe gradually extends, and there is a risk of being stepped on. Therefore, the welder can rotate the rotating shaft to horizontally extend the connected threaded pipes in the direction of the outer sheath pipe extension. According to the length of the outer sheath pipe extension, the screw head and the internal thread are used to connect the threaded pipes end to end. Each threaded pipe uses a cantilever to support a support wheel suspended below. In this way, the outer sheath pipe and the welding wire inside it can be hung on the upper surface of each support wheel, minimizing the part of the outer sheath pipe that falls to the ground and is stepped on, thereby improving the safety of the welding wire inside the outer sheath pipe.
[0009] The lower edge of the rotating shaft is fixed with a rotating disc, and the lower surface of the rotating disc is rotatably connected to the upper surface of the distribution box, so that the rotating disc is supported circumferentially while the rotating shaft rotates 360° to rotate one threaded pipe, facilitating the rotating shaft to maintain a vertical state.
[0010] A positioning bolt is threaded through the upper surface of the rotating disc. After the rotating disc stops rotating, the positioning bolt can be turned to abut against the upper surface of the distribution box, locking the rotating disc by friction. By reversing the positioning bolt, the distribution box can be unlocked to freely rotate the rotating disc within a 360° range.
[0011] A tripod is arranged below each threaded pipe, and the upper end of the tripod is in the form of a fan ring structure with an opening facing upward. The tripod supports each threaded pipe, facilitating the removal of the vertical load of the threaded pipe, and each threaded pipe can maintain a horizontal state while supporting the outer sheath pipe.
[0012] The wire feeding mechanism includes two vertically distributed rubber wheels, both of which are rotatably installed in the hollow inside the distribution box. A servo motor is also fixed inside the distribution box. The output end of the servo motor is fixedly connected to the middle of the lower rubber wheel. The welding wire is pulled through the gap between the two rubber wheels in advance. During welding, the servo motor is started to rotate the lower rubber wheel. At this time, the two rubber wheels grip the welding wire tightly, and the friction between them drives the welding wire to move forward along the outer sheath pipe at a uniform speed. When welding is stopped, the servo motor is controlled to stop rotating.
[0013] The technical effects achieved by the utility model are as follows:
[0014] The welding machine of the utility model, by using the machine case to provide high-voltage power supply for the welding gun, makes the electrode fork send out high-temperature electric arc to melt the welding wire, and the argon in the machine case gas storage tank is sprayed out from the welding gun along the pipeline, the argon is sprayed out around the welding wire as a protective gas, the molten drop, the molten pool and the air are isolated, the oxidation and pollution of the molten pool are avoided, thereby the quality of the welding joint is guaranteed, at the same time, the flow of the protective gas can also stabilize the welding arc, and the violent swing and unstable phenomenon of the electric arc in the welding process are avoided.
[0015] The welding wire feeder of the utility model, when welding outdoors, the welding wire is wound and put into the wire box in advance, one end is pulled through the wire feeding mechanism of the distribution box, and is sent to the welding gun along the outer sheath tube, and the wire feeding mechanism is synchronously operated at a uniform speed to send out the welding wire along with the power-on of the welding gun, since the welding personnel continuously advance along the welding area, the outer sheath tube gradually extends, and there is a risk of being stepped on, therefore, the welding personnel can rotate the rotating shaft to horizontally extend the connected threaded pipes towards the extension direction of the outer sheath tube, according to the length of the extension of the outer sheath tube, the threaded pipes are connected in a head-to-tail mode by using the screw head and the internal thread, each threaded pipe supports a support wheel in the air by using a cantilever, in this way, the outer sheath tube and the welding wire inside the outer sheath tube can be hung on the upper surfaces of the support wheels, the part of the outer sheath tube that falls on the ground and is stepped on is minimized, and the safety of the welding wire inside the outer sheath tube is improved.
