A gas-free shielded welding machine

Abstract

This utility model discloses a gas-free shielded welding machine, including a machine body with an installation groove. A control component is slidably connected in the installation groove, and a lever is fixedly connected to the control component. The control component can drive the lever to shake up and down. The lever abuts against the welding wire. When the welding wire is fed, the lever shakes up and down, and the welding wire vibrates. Therefore, during the wire feeding process, as the welding wire slides, the control component drives the lever to shake up and down. During the shaking process, the lever moves the welding wire, causing the welding wire to vibrate and causing the surface debris to fall off, preventing debris from accumulating at the weld joint and causing blockage. This design effectively removes debris from the surface of the welding wire, thereby ensuring stable welding.

Description

Technical Field

[0001] This utility model belongs to the technical field of welding equipment, and relates to gas shielded welding machines, particularly to a gas-free gas shielded welding machine. Background Technology

[0002] Gas shielded welding machines are industrial equipment that provide stable power and protective gas for the welding process. They are widely used in aerospace, shipbuilding, automotive and other fields. Their core components include a power system, wire feeding mechanism and gas control system. They use a mixture of carbon dioxide or argon as the protective medium and support both AC and DC power types. The DC model achieves high-efficiency welding through four-stage current conversion technology.

[0003] For example, a wire feeder for a MIG / MAG welding machine, disclosed in CN208051095U, includes a frame. A wire spool support shaft is installed at the rear end of the frame, and a wire spool is sleeved on the support shaft. A panel is installed at the front end of the frame, and a speed control switch is installed at the front end of the panel. A motor is installed inside the frame and electrically connected to the speed control switch. A roller is installed at the end of the motor. A wire pressing mechanism corresponding to the roller is installed on one side of the frame. A wire outlet tube corresponding to the wire pressing mechanism is installed on one side of the front end of the panel. A limiting plate corresponding to the wire outlet tube is inserted into the panel, and a clamping plate is connected to the rear end of the limiting plate.

[0004] The above-mentioned shielded welding machine is the most common type of shielded welding machine. However, during wire feeding, due to the presence of debris on the surface of the welding wire, the debris will accumulate at the weld joint during the wire feeding process, causing jamming and affecting wire feeding. Utility Model Content

[0005] This invention provides a gas-free shielded welding machine that can shake off debris from the welding wire, thereby preventing debris accumulation and weld blockage.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a gas-free shielded welding machine, including a machine body, characterized in that a mounting groove is provided on the machine body, a control component is slidably connected in the mounting groove, a lever is fixedly connected to the control component, the control component can drive the lever to shake up and down, the lever abuts against the welding wire, and when the welding wire is being fed, the lever shakes up and down and the welding wire vibrates.

[0007] A further preferred embodiment of this utility model is as follows: the control component includes a rack slidably connected in the mounting groove and a sector gear meshing with the rack. The paddle is fixedly connected to the sector gear. When the rack slides, the sector gear drives the paddle to sway up and down.

[0008] A further preferred embodiment of this utility model is: a cylinder for driving the rack to slide is fixedly connected to the machine body.

[0009] A further preferred embodiment of this invention is that the paddle is elastic.

[0010] A further preferred embodiment of this utility model is that the sector gear is rotatably connected to the mounting groove via a pin.

[0011] A further preferred embodiment of this utility model is: a chip collecting plate is fixedly connected to the machine body, and the chip collecting plate is located below the welding wire.

[0012] A further preferred embodiment of this utility model is that the chip collecting plate is an arc-shaped plate.

[0013] Compared with the prior art, this utility model includes a body with an installation groove. A control component is slidably connected in the installation groove, and a lever is fixedly connected to the control component. The control component can drive the lever to shake up and down. The lever abuts against the welding wire. When the welding wire is fed, the lever shakes up and down, and the welding wire vibrates. Therefore, during the wire feeding process, as the welding wire slides, the control component drives the lever to shake up and down. During the shaking process, the lever moves the welding wire, causing the welding wire to vibrate and causing the surface debris to fall off, avoiding the accumulation of debris at the weld joint and causing blockage. This design effectively removes debris from the surface of the welding wire, thereby ensuring stable welding. Attached Figure Description

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0018] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0019] Figures 1-3 As shown, a gas-free shielded welding machine includes a body 1, on which a mounting groove 2 is provided. The mounting groove 2 is a rectangular groove. A control component is slidably connected in the mounting groove 2. A lever 6 is fixedly connected to the control component. The control component can drive the lever 6 to shake up and down. The lever 6 abuts against the welding wire 5. When the welding wire 5 is being fed, the lever 6 shakes up and down and the welding wire 5 vibrates.

[0020] Figures 1-3 As shown, when removing chips from the welding wire 5, the control unit is activated. At this time, the control unit drives the lever 6 to shake up and down. Since the lever 6 and the welding wire 5 are in contact, the welding wire 5 also vibrates while the lever 6 is shaking. During the vibration, the chips on the welding wire 5 fall off, thereby achieving the purpose of chip removal and preventing chips from accumulating at the weld joint and causing blockage that affects welding. This design effectively ensures the smooth progress of welding.

[0021] Figures 1-3 As shown, the control components include a rack 7 slidably connected in the mounting groove 2 and a sector gear 4 meshing with the rack 7. A cylinder 3 for driving the rack 7 to slide is fixedly connected to the body 1. A paddle 6 is fixedly connected to the sector gear 4. When the rack 7 slides, the sector gear 4 drives the paddle 6 to swing up and down.

[0022] Figures 1-3 As shown, when feeding the wire, the cylinder 3 is activated. At this time, the output end of the cylinder 3 drives the rack 7 to slide up and down. At the same time, the sector gear 4, which meshes with the rack 7, rotates as the rack 7 slides. At this time, the paddle 6 fixed on the sector gear 4 slides along the arc as the sector gear 4 rotates, and in the process of sliding, it paddles the welding wire 5, thereby causing the welding wire 5 to vibrate and remove chips. This design plays the role of driving the paddle 6 to slide along the arc.

[0023] Figures 1-3 As shown, a sliding groove is provided on the inner side wall of the mounting groove 2. A slider is fixedly connected to the rack 7 and slides in the sliding groove. The slider is a T-shaped block. The cooperation between the slider and the sliding groove can limit the sliding range of the rack 7 and prevent the rack 7 from separating from the sector gear 4 when sliding. The T-shaped slider design can prevent the slider from separating from the sliding groove when the rack 7 slides, further limiting the range of motion of the slider.

[0024] Figures 1-3As shown, the lever 6 is elastic and made of rubber. Therefore, when the lever 6 moves the welding wire 5, the lever 6 deforms, thereby preventing the lever 6 from damaging the welding wire 5 during the process of moving the wire and affecting its use. This design effectively protects the welding wire 5.

[0025] Figures 1-3 As shown, the sector gear 4 is rotatably connected to the mounting groove 2 via the pin 8. The pin 8 can position the sector gear 4 in the mounting groove 2, preventing the sector gear 4 from shifting during rotation and affecting its use. This design plays a positioning role.

[0026] Figures 1-3 As shown, a chip collection plate 9 is fixedly connected to the body 1. The chip collection plate 9 is located below the welding wire 5. This design can collect the chips that fall from the welding wire 5, thereby preventing the falling chips from scattering and affecting the working environment.

[0027] Figures 1-3 As shown, the chip collection plate 9 is an arc-shaped plate, which can better collect falling debris.

[0028] The above describes a gas-free shielded welding machine provided by this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The descriptions of the embodiments above are only for the purpose of helping to understand this utility model and its core ideas. It should be noted that those skilled in the art can make several improvements and modifications to this utility model without departing from its principle, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
