Description

Technical Field

[0001] This utility model relates to the field of welding torch technology, specifically a welding torch for use in welding lines to reduce spark spatter. Background Technology

[0002] The welding torch is one of the main pieces of equipment in hot air welding. The welding torch refers to the part that performs the welding operation during the welding process. It is shaped like a gun and is flexible, convenient and quick to use. The process is simple. It utilizes the heat generated by the high current and high voltage of the welding machine to concentrate at the end of the welding torch, melt the welding wire, and the molten welding wire penetrates into the part to be welded. After cooling, the welded objects are firmly connected into one.

[0003] Existing welding torches designed to reduce sparks and spatter in cable bonding are mostly optimized to facilitate cable head welding operations. For example, Chinese utility model patent application CN202022479144.3 discloses a welding torch, which includes: a torch body, a torch barrel connected to the torch body and having a cavity for containing solder paste; a heating head connected to the end of the torch barrel away from the torch body, the heating head having a heating channel communicating with the cavity, and the end of the heating channel away from the cavity communicating with the outside; and a solder pusher assembly disposed inside the torch body and extending into the torch barrel. The solder pusher assembly can push the solder paste in the cavity into the heating channel, and after heating, push it out to the outside through the heating channel, solving the problem of difficult 2M cable head welding operations in the prior art.

[0004] While the aforementioned welding torches for reducing sparks in welding lines offer certain advantages in facilitating cable head welding operations, they still have some drawbacks: during welding operations, sparks are generated at the welding tip of the torch and at the parts to be welded, and the size of the sparks varies, which can easily cause spattering to the welder. The worker usually needs to use their other hand to hold a protective shield to block the sparks, making it impossible for the worker to work with both hands together during welding, thus making the operation cumbersome.

[0014] Preferably, one end of the arm is hinged to one end of the push rod and is movably connected, and the lower end of the arm is perpendicular to the push rod, so that pushing the push rod causes the arm to change its tilt.

[0015] Preferably, the baffle is movably engaged with the placement slot, and the baffle can be folded ninety degrees, changing from a horizontal to a vertical orientation.

[0016] Preferably, when the baffle is folded and placed vertically, it can form a blocking surface to reduce spark splashing.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a welding torch for reducing spark spatter in welding lines, which has the following beneficial effects:

[0019] 1. This welding torch for reducing sparks in welding lines allows personnel to insert the rear end of the welding end into the frame through the front port of the frame before welding operations, so that the rear end can be engaged by the drive parts inside the frame. Personnel then control the torch from the control panel to make the mating parts inside the frame cooperate with the welding end to complete the welding operation.

[0020] 2. This welding torch for reducing sparks in welding lines features a blocking structure. Operators manually push and pull a lever to adjust the arm's tilt, which in turn exerts a pushing force on the baffle, causing it to bend 90 degrees. The operator then presses down on a limiting block, causing one end to engage with a recessed hole on the lever, thus restricting the lever's position. The four baffles are positioned at 90 degrees to the frame, acting as a blocking force at the front of the frame, thereby reducing sparks during operation. Attached Figure Description

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1 A welding torch for reducing spark spatter in a welding line includes a handle 1, a welding torch body 2, and a welding end 3. The welding end 3 is installed at the front of the welding torch body 2, and the handle 1 is embedded and connected to the lower rear end of the welding torch body 2.

[0029] Please see Figure 2-3A welding torch for reducing spark spatter in a welding line, the torch body 2 includes a frame 21, a blocking structure 22, a slide 23, a push rod 24, a control panel 25, and a placement slot 26. The blocking structure 22 is installed on the surface of the frame 21, the slide 23 is disposed through the surface of the frame 21, the push rod 24 penetrates into the inner side of the slide 23, the control panel 25 and the frame 21 are integrated, and the placement slot 26 and the frame 21 are integrated. The front end of the frame 21 is installed with the rear end of the welding end 3 and is electrically connected internally. The lower end of the frame 21 is installed with the handle 1. The placement slot 26 and the push rod 24 are each provided in four places, located at the top, bottom, left and right ends of the frame 21, and each placement slot 26 matches each blocking structure 22.

[0030] Please see Figure 4-5 A welding torch for reducing spark spatter in a welding line includes a blocking structure 22 comprising a baffle 221, an arm 222, a base frame 223, a limiting block 224, and a slot 225. The upper end of the arm 222 is hinged to the baffle 221, and the lower end of the arm 222 is movably engaged with the base frame 223. The side end of the base frame 223 is hinged to the lower end of the baffle 221. The limiting block 224 is movably engaged in the base frame 223. The slot 225 is an integral structure with the base frame 223. The bottom of the base frame 223 is fixed. Fixedly connected to the inner bottom surface of the placement slot 26, one end of the arm 222 is hinged to one end of the push rod 24 and is movably engaged. The lower end of the arm 222 is perpendicular to the push rod 24. Pushing the push rod 24 causes the arm 222 to tilt. The baffle 221 is movably engaged with the placement slot 26. The baffle 221 can be folded ninety degrees, changing from a horizontal to a vertical position. When the baffle 221 is folded and placed vertically, it can form a blocking surface to reduce sparks.

[0031] In summary, before welding, the rear end of welding end 3 is inserted into the frame 21 through the front port, allowing it to be engaged with the internal drive components. The operator then commands the welding end 3 via the control panel 25 to complete the welding operation. A blocking structure 22 is installed so that before welding, the operator manually pushes and pulls the push rod 24, causing it to move along the slide rail 23. The front end of the push rod 24 is hinged to one end of the arm 222, allowing the arm 222 to move under the pushing and pulling force. The tilt of the lever 222 changes, thereby generating a pushing force on the baffle 221, causing the baffle 221 to gradually move from its original horizontal position to a vertical position until the baffle 221 bends at a 90-degree angle. Then, the operator presses down on the limiting block 224, causing one end of it to engage in the recessed hole on the push rod 24, thus restricting the position of the push rod 24. This ensures that the tilt of the lever 222 remains unchanged, and consequently, the position of the baffle 221 remains unchanged. The baffles 221, which are set in four places, are all tilted at a 90-degree angle to the frame 21, and play a blocking role at the forward position of the frame 21, thereby reducing the sparks flying during the operation of the device.
