Description

Technical Field

[0001] This application relates to the field of welding technology, and in particular to a detachable liquid-cooled welding gun barrel. Background Technology

[0002] MIG (Metal Inert Gas) and MAG (Metal Inert Gas) welding technologies, as important processes in modern metal processing, are widely used in the manufacture and repair of various metal structures due to their high-quality welding results and high production efficiency. Both welding methods use welding wire as the consumable electrode and an inert gas (such as argon) or an active gas (such as argon mixed with a small amount of carbon dioxide or oxygen) as the shielding gas. This effectively isolates impurities such as oxygen and nitrogen in the air from interfering with the welding process, thus ensuring the purity and mechanical properties of the weld.

[0003] In high-current welding of medium and heavy plates, the welding torch must withstand an extremely high heat load due to the high welding heat and long duration. To address this, liquid-cooled welding torches have been developed. These torches use internally circulating cooling water to remove the large amount of heat generated during operation, effectively extending the torch's lifespan while maintaining the stability of the welding process and the concentration of the arc, further improving welding quality and efficiency.

[0004] However, despite the significant advantages of liquid-cooled welding torches in welding medium and heavy plates, they still face some challenges in practical applications. When the torch barrel is damaged, existing liquid-cooled welding torch designs often make the barrel replacement process complex and time-consuming, and may lead to coolant leakage during the replacement process, increasing the difficulty and complexity of the replacement operation. Summary of the Invention

[0005] The purpose of this application is to provide a detachable liquid-cooled welding gun barrel to solve the problem of difficult replacement of liquid-cooled welding gun barrels in the prior art.

[0006] To solve the above-mentioned technical problems, this application adopts the following technical solution:

[0007] This application provides a detachable liquid-cooled welding gun barrel, including: a barrel body, a cooling channel defined within the barrel body, the barrel body including a connector seat, a coolant connector provided on one end face of the connector seat, and the cooling channel having a port located on the end face of the coolant connector.

[0008] A socket, detachably mounted on the connector base, the socket defining a coolant hole to accommodate the coolant connector;

[0009] A water-locking component is disposed within the cold liquid hole and is used to block or open the cold liquid hole;

[0010] When the socket and the connector are in the installed state, the coolant connector abuts against the water-locking component, opening the coolant hole; when the socket and the connector are in the disassembled state, the water-locking component can completely block the coolant hole.

[0011] In this design, coolant enters the welding torch body through a coolant port in the socket. A water-locking component is installed inside the coolant port to automatically seal it when the socket is removed, preventing coolant leakage. When the socket is installed correctly, the coolant connector presses against the water-locking component, opening the coolant port and allowing coolant to enter the coolant channel. This design not only ensures normal coolant flow during welding but also effectively prevents coolant leakage when replacing the torch barrel. The socket is detachably mounted on the connector base; when the welding torch body needs to be replaced, simply removing the socket allows for easy removal of the torch body, greatly simplifying the replacement process.

[0012] Optionally, the water-locking component includes:

[0013] A water-locking outer cylinder is axially disposed within the cold liquid hole. The water-locking outer cylinder has a water-locking step, which divides the interior of the water-locking outer cylinder into a water passage hole and a water-locking hole. The diameter of the water passage hole is larger than the diameter of the water-locking hole. The water-locking outer cylinder has a water-locking plug on one side of the water passage hole, and the water-locking plug defines a first hole at its upper part.

[0014] A water-locking core is axially disposed inside the water-locking outer cylinder. The two ends of the water-locking core define a second hole and a third hole, respectively. The side wall of the water-locking core defines a fourth hole and a fifth hole, respectively communicating with the second hole and the third hole. The outer wall of the water-locking core between the fourth hole and the fifth hole defines a first sealing groove circumferentially. A first sealing ring is disposed in the first sealing groove. When the socket and the connector are in a disassembled state, the first sealing ring is sealed to the water-locking hole.

[0015] A compression spring is disposed between the water-locking seal and the water-locking core to press against the water-locking core.

[0016] In this solution, when the socket and connector are in the disassembled state, the first sealing ring can enter the water-locking hole under the action of the compression spring and fit tightly against the inner wall of the water-locking hole, thereby completely sealing the water-locking hole and preventing coolant from flowing out.

[0017] During the installation of the socket and connector, the coolant connector enters the outer cylinder of the water-locking sleeve and presses against the water-locking core. Under the pressure of the coolant connector, the water-locking core compresses the spring and moves it towards the water-locking sealing side. When the socket and connector are installed, the first sealing ring will disengage from the water-locking hole and enter the water-passing hole, and at this time, the fifth hole will also be located in the water-passing hole. It should be noted that there should be a gap between the first sealing ring and the water-passing hole to allow coolant flow.

[0018] In this design, the coolant flow path into the cold welding torch barrel is as follows: the coolant first enters the coolant hole, then through the first hole into the water inlet, then sequentially through the second, fourth, and fifth holes into the third hole, and finally through the third hole into the coolant connector, and then into the torch barrel body. After heat exchange in the cold welding torch barrel, the coolant returns through the reverse flow path.

[0019] Optionally, the water-locking core has a limiting part on the outer wall between the first sealing groove and the fourth hole, and the limiting part can abut against the water-locking step.

[0020] This design uses a limiting part to limit the position of the water-locking core, preventing it from detaching from the outer water-locking cylinder under the action of the compression spring. When the socket and connector are detached, the limiting part abuts against the water-locking step under the action of the compression spring, thereby limiting the position of the water-locking core.

[0021] Optionally, the outer wall of the water-locking outer cylinder is circumferentially defined with a plurality of second sealing grooves, and a second sealing ring is provided in the second sealing groove, and the second sealing ring is sealed to the inner wall of the cold liquid hole.

[0022] To prevent coolant from leaking out through the gap between the outer wall of the water-locking outer cylinder and the inner wall of the cooling hole, this solution uses a second sealing ring to increase the sealing between the two.

[0023] Optionally, the coolant connector includes a water inlet connector and a water return connector. The water inlet connector defines the water inlet and outlet, and the water return connector defines the water return outlet. The water inlet and the water return outlet are connected through the cooling channel.

[0024] In this design, the coolant connection consists of two parts: an inlet connector and a return connector. The inlet connector defines the inlet and outlet for coolant to enter the cooling channel. The return connector defines the outlet for coolant to exit the cooling channel.

[0025] Optionally, the barrel body further includes a tube body, which is connected to the connector seat on the side opposite to the coolant connector, and a nozzle is provided at one end of the tube body.

[0026] Optionally, the connector seat is provided with a guide wire connector on the same end face as the coolant connector, and the socket defines a guide wire hole to accommodate the guide wire connector.

[0027] In this design, the wire guide connector is fixed to the connector seat and arranged side by side with the coolant connector, used to connect the welding wire output from the wire feeder. The wire guide hole is opened on the socket, corresponding to the wire guide connector, to allow the welding wire to pass through when the socket is installed on the connector seat.

[0028] Optionally, the connector seat is provided with an air inlet connector on the same end face as the coolant connector, and the socket defines an air inlet / outlet hole to accommodate the air inlet connector.

[0029] The gas inlet connector provides a stable gas input path, ensuring a continuous and stable supply of the gas required during welding to the welding torch nozzle. The gas inlet port, corresponding to the gas inlet connector, is located on the socket and allows gas passage when the socket is installed onto the connector base.

[0030] Optionally, the socket is connected to the connector seat by a lock nut.

[0031] In this design, both the socket and the connector have threads, and a locking nut is tightened onto these threads by rotation, ensuring a tight connection between the socket and the connector. The locking nut connection is relatively simple and requires no special tools or skills, making the assembly and disassembly of the socket and connector much easier.

[0032] Compared with existing technologies, the beneficial effects achieved by this application are as follows: In this application, coolant enters the cooling channel inside the welding torch body through the coolant hole in the socket. A water-locking component is installed inside the coolant hole to automatically seal the coolant hole when the socket is removed, preventing coolant leakage. When the socket is installed in place, the coolant connector presses against the water-locking component, causing it to open the coolant hole and allowing coolant to enter the cooling channel. This application not only ensures the normal flow of coolant during the welding process but also effectively prevents coolant leakage when replacing the torch barrel.

[0033] In addition, the socket in this application is detachably mounted on the connector. When the welding torch body needs to be replaced, the welding torch body can be easily removed simply by disassembling the socket, which greatly simplifies the replacement process and reduces replacement time and downtime.

Detailed Implementation

[0046] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure / application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0047] Example 1

[0048] This embodiment describes a detachable liquid-cooled welding torch barrel, referencing... Figures 1 to 3 The detachable liquid-cooled welding torch barrel in this embodiment includes a barrel body, a socket 200, and a water-locking assembly 300. The barrel body includes a connector 100, with a coolant connector 110 on one end face of the connector 100, allowing coolant to enter the barrel body through the coolant connector 110 for welding cooling. Specifically, the barrel body also includes a tube 400 connected to the connector 100 on the side opposite to the coolant connector 110, with a nozzle 500 at one end of the tube 400. The connector 100, tube 400, and nozzle 500 together define a cooling channel. This cooling channel has an end face on the coolant connector. The cooling channel is the path for coolant flow within the barrel, carrying away heat from the welding torch nozzle 500.

[0049] Further reference Figure 10 The coolant connector 110 includes an inlet connector 111 and a return connector 112. The inlet connector 111 defines the inlet and outlet ports, and the return connector 112 defines the outlet and return port. The inlet and outlet ports are connected through a cooling channel. The coolant enters the cooling channel through the inlet port, flows inside the cooling channel and absorbs heat, and then flows out through the return port.

[0050] Furthermore, the socket 200 is detachably mounted on the connector 100. It can be connected via a snap-fit ​​or a fastening nut. In this embodiment, the socket 200 and the connector 100 are connected by a locking nut 600. Specifically, both the socket 200 and the connector 100 have threads, and the locking nut 600 is tightened onto these threads by rotation, ensuring a tight connection between the socket and the connector 100. The locking nut 600 connection is relatively simple and requires no special tools or skills, making the assembly and disassembly of the socket and connector 100 more convenient. It should be noted that in this embodiment, if the detachable liquid-cooled welding gun barrel is damaged, only the barrel body needs to be replaced.

[0051] refer to Figure 4 The socket defines a coolant hole 210 to accommodate the coolant connector 110. In this embodiment, there are two coolant holes 210, which are used to accommodate the inlet connector 111 and the return connector 112, respectively. The coolant in the condensation hole connected to the inlet connector 111 enters the cooling channel through the inlet, flows inside the cooling channel and absorbs heat, and then flows out through the return port into the condensation hole connected to it, and returns to the external cooling system for recooling.

[0052] Furthermore, a water-locking component 300 is installed inside the coolant hole 210 to automatically seal the coolant hole 210 when the socket is removed, preventing coolant leakage. When the socket is installed, the coolant connector 110 presses against the water-locking component 300, opening the coolant hole 210 and allowing coolant to enter the welding torch body for circulation. The water-locking component 300 not only ensures the normal flow of coolant during welding but also effectively prevents coolant leakage when changing the torch barrel.

[0053] Reference 4 and Figure 10 In this embodiment, a wire guide connector 120 is provided on the same end face of the coolant connector 110 as the connector base 100. A wire guide hole 220 is defined on the socket to accommodate the wire guide connector 120. The wire guide connector 120 is fixed on the connector base 100 and arranged parallel to the coolant connector 110, and is used to connect the welding wire output from the wire feeder. The wire guide hole 220 is formed on the socket, corresponding to the wire guide connector 120, to allow the welding wire to pass through when the socket is installed on the connector base 100.

[0054] Furthermore, the connector 100 is also provided with an inlet connector 130 on the same end face as the coolant connector 110, and the socket defines an inlet / outlet port 230 to accommodate the inlet connector 130. The inlet connector 130 provides a stable gas input channel, ensuring that the gas required during welding can be continuously and stably delivered to the welding torch nozzle 500. The inlet port 230 is formed on the socket, corresponding to the inlet connector 130, to allow gas to pass through when the socket is installed on the connector 100.

[0055] Example 2:

[0056] Based on the same inventive concept as Embodiment 1, refer to Figures 6 to 9 In this embodiment, the water-locking assembly 300 includes a water-locking outer cylinder 310 axially disposed within the coolant hole 210, the outer wall of which is sealed to the inner wall of the cooling hole. In some embodiments, the water-locking outer cylinder 310 may be integrally formed with the coolant hole 210. Further, the water-locking outer cylinder 310 has a water-locking step 311, which divides the interior of the water-locking outer cylinder 310 into a water passage hole 312 and a water-locking hole 313. The diameter of the water passage hole 312 is larger than that of the water-locking hole 313, and the water-locking outer cylinder 310 has a water-locking plug 314 on one side of the water passage hole 312, with a first hole 315 defined on the water-locking plug 314.

[0057] refer to Figure 7Furthermore, a water-locking core 320 is axially arranged inside the water-locking outer barrel, with a second hole 321 and a third hole 322 defined at both ends of the water-locking core 320. A fourth hole 323 and a fifth hole 324, respectively communicating with the second hole 321 and the third hole 322, are defined on the side wall of the water-locking core 320. A first sealing groove 326 is circumferentially defined on the outer wall of the water-locking core 320 between the fourth hole 323 and the fifth hole 324, and a first sealing ring 330 is disposed within the first sealing groove 326. When the socket and connector 100 are in the disassembled state, the first sealing ring 330 is sealed to the water-locking hole 313. A compression spring 340 is disposed between the water-locking plug 314 and the water-locking core 320, and the compression spring 340 is used to press against the water-locking core 320. Furthermore, the water-locking seal 314 is provided with a spring seat 360 on the side opposite to the water-locking core 320, and a sixth hole 361 connected to the first hole 315 is defined on the spring seat 360.

[0058] In this embodiment, when the socket and connector 100 are in a disassembled state, under the action of the compression spring 340, the first sealing ring 330 can enter the water-locking hole 313 and fit tightly against the inner wall of the water-locking hole 313, thereby completely sealing the water-locking hole 313 and preventing coolant from flowing out.

[0059] Reference 8 to Figure 9 During the installation of the socket and connector 100, the coolant connector 110 enters the interior of the water-locking outer cylinder 310 and presses against the water-locking core 320. Under the pressure of the coolant connector 110, the water-locking core 320 compresses the compression spring 340 towards the water-locking seal 314. When the socket and connector 100 is installed, the first sealing ring 330 will disengage from the water-locking hole 313 and enter the water passage hole 312, and at this time, the fifth hole 324 will also be located in the water passage hole 312. It should be noted that there should be a gap between the first sealing ring 330 and the water passage hole 312 to allow coolant flow.

[0060] The coolant flow path into the cold welding torch barrel is as follows: the coolant first enters the coolant hole 210. Then, it sequentially enters the water inlet 312 through the first hole 315 and the sixth hole 361. Next, it sequentially enters the third hole 322 through the second hole 321, the fourth hole 323, and the fifth hole 324. The third hole 322 is connected to the water inlet of the water inlet connector 111, allowing the coolant to enter the cooling channel within the torch barrel body through the third hole 322. After heat exchange in the cooling channel, the coolant flows out through the return port and returns through the opposite flow path within the coolant hole 210.

[0061] In this embodiment, the water-locking core 320 has a limiting part 325 on its outer wall between the first sealing groove 326 and the fourth hole 323. The limiting part 325 can abut against the water-locking step 311. By limiting the water-locking core 320 with the limiting part 325, the water-locking core 320 is prevented from detaching from the water-locking outer cylinder 310 under the action of the compression spring 340. When the socket and connector 100 are in the disassembled state, the limiting part 325 abuts against the water-locking step 311 under the action of the compression spring 340, thereby limiting the position of the water-locking core 320.

[0062] To prevent coolant leakage through the gap between the outer wall of the water-locking outer cylinder 310 and the inner wall of the cooling hole, this solution uses a second sealing ring 350 to increase the sealing between the two. Specifically, the outer wall of the water-locking outer cylinder 310 is circumferentially defined with several second sealing grooves 316, and the second sealing rings 350 are provided in the second sealing grooves 316, which are sealed to the inner wall of the coolant hole 210.

[0063] The above description is only a preferred embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of this disclosure / application, and these improvements and modifications should also be considered within the protection scope of this disclosure / application.
