Description

Technical Field

[0001] This utility model relates to the field of carbon steel submerged arc welding wire production technology, specifically a heat treatment device for carbon steel submerged arc welding wire. Background Technology

[0002] Carbon steel submerged arc welding wire is a type of welding material, mainly used for welding carbon steel and corresponding low-strength alloy steels. In the production process of carbon steel submerged arc welding wire, heat treatment is required to improve the performance and quality of the welding wire.

[0003] A Chinese patent with publication number CN216141592U discloses a heat treatment device for stainless steel welding wire, including a base plate and a support ring control unit. The base plate has a mesh belt conveyor in the middle of its upper surface. Two evenly distributed support frames are fixedly connected to the upper surface of the base plate. Support rings are rotatably connected to the upper inner sides of each of the two support frames. Two sets of heating tubes are fixedly connected between the two support rings. The two sets of heating tubes are evenly distributed, with five heating tubes in each set. Two evenly distributed support plates are fixedly connected to the front side of the upper surface of the base plate, and a mounting block is fixedly connected to the front side of the upper surface of the base plate. This heat treatment device for stainless steel welding wire provides uniform heat treatment, has a short heat treatment time, high efficiency, and is very convenient.

[0004] In the aforementioned heat treatment device for welding wire, the welding wire needs to be placed on a mesh belt conveyor for heating treatment. Since the bottom side of the welding wire is in direct contact with the conveyor mesh belt, there will be a temperature difference between the contact surface and the non-contact surface during the heating process, resulting in uneven heating of the welding wire and thus affecting the heat treatment effect of the welding wire. Therefore, a heat treatment device for carbon steel submerged arc welding wire is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology and solve the problems mentioned in the background, this utility model proposes a heat treatment device for carbon steel submerged arc welding wire.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A heat treatment device for carbon steel submerged arc welding wire, comprising a cavity base, a tank rotatably mounted on the cavity base, multiple heating tubes arranged on the inner wall of the tank, the heating tubes being evenly spaced, a first motor installed inside the cavity base, the output end of the first motor connected to a rotating shaft, a cavity rotating disk fixedly connected to the top end of the rotating shaft, multiple rotating rods rotatably mounted inside the cavity rotating disk, a small gear fitted at the bottom end of each rotating rod, and a placement disk installed at the top end of each rotating rod, the placement disk being positioned above the cavity rotating disk, a second motor mounted on the top side of the cavity rotating disk, a large gear also mounted at the output end of the second motor, the large gear meshing with the small gear, and both the large gear and the small gear being positioned within the cavity rotating disk. Inside the turntable, a battery box is installed on the top side of the hollow rotating disk. The battery box supplies power to the second motor. When heat-treating the welding wire, the welding wire is first placed between two clamping plates. Then, the motor is started, causing the bidirectional lead screw to rotate. This causes the two movable blocks to move the two clamping plates closer together, thus clamping and fixing the welding rod. Next, the first motor is started, causing the hollow rotating disk to rotate the clamped welding rod. At the same time, the second motor is started, causing the large gear to rotate. This forces the small gear to rotate the rotating rod, which in turn causes the disk and the clamped welding rod to rotate. Through the rotation and rotation of the welding wire, the welding wire can be heated evenly in all directions, avoiding defects such as stress concentration, cracks, and porosity that may occur inside the welding wire due to uneven heating. This improves the overall quality of the welding wire and ensures its stability and reliability in subsequent use.

[0007] Preferably, a driven gear ring is fitted on the outer surface of the tank body, and a third motor is installed on the top side of the cavity base. A drive gear is installed at the output end of the third motor, and the drive gear meshes with the driven gear ring. During the heat treatment of the welding wire, the operation of the third motor causes the drive gear to rotate, which forces the driven gear ring to drive the tank body and the internal heating tube to rotate. The rotation of the heating tube helps to achieve a uniform temperature distribution inside the tank, further ensuring the uniformity of the welding wire's heating.

[0008] Preferably, each placement disc has a groove, and each groove contains two movable blocks. A clamping plate is fixed to the top of each movable block. A bidirectional lead screw is rotatably installed in each groove, passing through the movable blocks. A motor is installed on the outer wall of each placement disc, and the output end of the motor is connected to one end of the bidirectional lead screw. When fixing the welding wire, the welding wire is first placed between the two clamping plates. Then, the motor is started, causing the bidirectional lead screw to rotate. With the cooperation of the grooves, the two movable blocks drive the two clamping plates closer together, thereby clamping and fixing the welding wire. This prevents the welding wire from shaking or shifting, which could affect the heat treatment effect and ensure the stability of the welding wire during the heat treatment process.

[0009] Preferably, the top port of the tank is rotatably fitted with a sealing cover plate via a threaded connection, and the top side of the sealing cover plate is fitted with a handle. When using the device, the port of the tank can be opened or closed as needed due to the structural design of the sealing cover plate.

[0010] Preferably, a controller is installed on the top side of the cavity base, and the controller is used to control the start and stop of the first motor, the motor and the third motor. When using the device, by setting the controller, it can be used to control the start and stop of the first motor, the motor and the third motor as needed.

[0011] The advantages of this utility model are:

[0012] 1. In the heat treatment of welding wire, this utility model first places the welding wire between two clamping plates, then starts the motor to rotate the bidirectional lead screw, which in turn causes the two movable blocks to move the two clamping plates closer together, thereby clamping and fixing the welding wire. Then, the first motor is started to rotate the cavity rotating disk and the clamped welding wire. At the same time, the second motor is started to rotate the large gear, which forces the small gear to rotate the rotating rod. The rotating rod then causes the placement disk and the clamped welding wire to rotate. Through the rotation and rotation of the welding wire, the welding wire can be heated in all directions and evenly, avoiding defects such as stress concentration, cracks, and porosity that may occur inside the welding wire due to uneven heating. This improves the overall quality of the welding wire and ensures the stability and reliability of the welding wire in subsequent use.

[0013] 2. In the heat treatment process of the welding wire, the third electric motor operates to make the driving gear rotate, which forces the driven gear ring to drive the tank and the internal heating tube to rotate. The rotation of the heating tube helps to make the temperature distribution in the tank uniform, further ensuring the uniformity of the welding wire heating. Attached Figure Description

[0022] 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 scope of protection of the present utility model.

[0023] Please see Figure 1-6As shown, a heat treatment device for carbon steel submerged arc welding wire includes a cavity base 1, a tank 2 rotatably mounted on the cavity base 1, multiple heating tubes 3 arranged on the inner wall of the tank 2 at equal intervals, a first motor 4 installed inside the cavity base 1, the output end of the first motor 4 connected to a rotating shaft, a cavity rotating disk 5 fixedly connected to the top end of the rotating shaft, multiple rotating rods 6 rotatably mounted inside the cavity rotating disk 5, a small gear 7 fitted at the bottom end of each rotating rod 6, and a placement disk 8 installed at the top end of each rotating rod 6, with the placement disk 8 positioned above the cavity rotating disk 5, a second motor 14 installed on the top side of the cavity rotating disk 5, a large gear 15 installed at the output end of the second motor 14, and the large gear 15 meshes with the small gear 7, both the large gear 15 and the small gear 7 being located inside the cavity rotating disk 5, and a battery box 16 installed on the top side of the cavity rotating disk 5. The battery box 16 supplies power to the second motor 14. During operation, when heat-treating the welding wire, the welding wire is first placed between the two clamping plates 11. Then, the motor 13 is started, causing the bidirectional lead screw 12 to rotate. This causes the two movable blocks 10 to move the two clamping plates 11 closer together, thereby clamping and fixing the welding rod. Then, the first motor 4 is started, causing the cavity rotating disk 5 to rotate the clamped and fixed welding rod. At the same time, the second motor 14 is started, causing the large gear 15 to rotate, which forces the small gear 7 to rotate the rotating rod 6. This causes the rotating rod 6 to rotate the placement disk 8 and the clamped and fixed welding rod. Through the rotation and rotation of the welding wire, the welding wire can be heated in all directions and evenly, avoiding defects such as stress concentration, cracks, and pores that may occur inside the welding wire due to uneven heating. This improves the overall quality of the welding wire and ensures the stability and reliability of the welding wire in subsequent use.

[0024] Please see Figure 1-2 As shown, a driven gear ring 17 is fitted on the outer surface of the tank body 2, and a third motor 18 is installed on the top side of the cavity base 1. A drive gear 19 is installed at the output end of the third motor 18, and the drive gear 19 meshes with the driven gear ring 17. During operation, in the heat treatment process of the welding wire, the third motor 18 operates to make the drive gear 19 rotate, which forces the driven gear ring 17 to drive the tank body 2 and the internal heating tube 3 to rotate. The rotation of the heating tube 3 helps to achieve a uniform temperature distribution inside the tank body 2, further ensuring the uniformity of the welding wire heating.

[0025] Please see Figure 6As shown, each placement disc 8 has a groove 9, and each groove 9 has two movable blocks 10. Each movable block 10 has a clamping plate 11 fixed to its top. Each groove 9 has a bidirectional lead screw 12 rotatably installed in it, and the bidirectional lead screw 12 passes through the movable block 10. Each placement disc 8 has a motor 13 installed on its outer wall, and the output end of the motor 13 is connected to one end of the bidirectional lead screw 12. During operation, before heat treatment of the welding wire, it needs to be fixed. First, the welding wire is placed between the two clamping plates 11. Then, the motor 13 is started, causing the bidirectional lead screw 12 to rotate. With the cooperation of the groove 9, the two movable blocks 10 drive the two clamping plates 11 to move closer to each other, thereby clamping and fixing the welding wire and preventing the welding wire from shaking or shifting, which would affect the heat treatment effect. This ensures the stability of the welding wire during the heat treatment process.

[0026] Please see Figure 1 As shown, a sealing cover plate 20 is rotatably fitted to the top port of the tank body 2 via a threaded connection, and a handle 21 is fitted to the top side of the sealing cover plate 20; during operation, when using this device, the port of the tank body 2 can be opened or closed as needed due to the structural design of the sealing cover plate 20.

[0027] A controller 22 is installed on the top side of the cavity base 1, and the controller 22 is used to control the start and stop of the first motor 4, the motor 13 and the third motor 18. When the device is in operation, by setting the controller 22, it can be used to control the start and stop of the first motor 4, the motor 13 and the third motor 18 as needed.

[0028] Working Principle: In the aforementioned heat treatment device for welding wire, the welding wire needs to be placed on a mesh conveyor for heating. Since the bottom of the welding wire is in direct contact with the conveyor belt, a temperature difference occurs between the contact and non-contact surfaces during heating, resulting in uneven heating and affecting the heat treatment effect. Therefore, to address this problem, a heat treatment device for carbon steel submerged arc welding wire is proposed. During heat treatment, the welding wire is first placed between two clamping plates 11. Then, the motor 13 is started, causing the bidirectional lead screw 12 to rotate. This causes the two movable blocks 10 to move the two clamping plates 11 closer together, thus clamping and fixing the welding wire. Next, the first motor 4 is started, causing the cavity rotating disk 5 to rotate the clamped welding wire. Simultaneously, the second motor 14 is started, causing the large gear 15 to rotate, which in turn forces the small gear 7 to drive the rotating rod 6 to rotate. This, in turn, causes the rotating rod 6 to drive the placement disc 8 and the clamped welding rod to rotate. Through the rotation and rotation of the welding wire, the welding wire can be heated evenly in all directions, avoiding defects such as stress concentration, cracks, and porosity that may occur inside the welding wire due to uneven heating. This improves the overall quality of the welding wire and ensures its stability and reliability in subsequent use. During the heat treatment of the welding wire, the third motor 18 operates, causing the drive gear 19 to rotate, which in turn forces the driven gear ring 17 to drive the tank 2 and the internal heating tube 3 to rotate. The rotation of the heating tube 3 helps to evenly distribute the temperature inside the tank 2, further ensuring the uniformity of the welding wire's heating.
