Description

Technical Field

[0001] The utility model relates to an automatic flux funnel device for submerged arc welding, belonging to the technical field of flux funnel devices. Background Art

[0002] Submerged arc welding is a welding method in which an electric arc burns under a flux layer. It is commonly used in the production of important steel structures such as pressure vessels, pipe segment manufacturing, box beams and columns. The granular flux is placed in a funnel device, and then flows out from the bottom of the funnel and is evenly deposited on the assembled workpiece. The welding wire is fed to the flux arc zone by a wire feeding mechanism. The continuously fed welding wire generates an arc under the flux layer and between the weldment. The heat of the arc melts the welding wire, workpiece and flux to achieve the welding purpose.

[0003] When using flux, it is usually poured directly into the funnel, and then falls from the flux leakage port to the surface of the workpiece. Due to the lack of an opening and closing device, the opening and closing of the flux leakage port needs to be manually controlled. If a solenoid valve is directly added to the leakage port, the working state of the solenoid valve affects the use of the funnel. If the solenoid valve fails, the funnel cannot be used. Therefore, an automatic flux funnel device for submerged arc welding is proposed to address the above problems. Utility Model Content

[0022] Example 1

[0023] See also Figure 1-5 , the utility model provides a technical solution:

[0024] A submerged arc welding automatic flux funnel device comprises a funnel shell 1, a flux leakage port 2 and a latch port 3, wherein the flux leakage port 2 is fixedly connected to the bottom of the funnel shell 1, the latch port 3 is fixedly connected to one side of the funnel shell 1, an electric switch 4 is arranged on the surface of the funnel shell 1, a manual pull ring 5 is arranged below the electric switch 4, an electromagnetic block 6 is arranged in the funnel shell 1, a material discharge through hole 7 and a groove 9 are provided in the funnel shell 1, a movable baffle 8 is slidably connected in the material discharge through hole 7 provided in the funnel shell 1, a guide plate 16 is fixedly connected to one side of the movable baffle 8, pulleys 15 are provided on the upper and lower sides of the guide plate 16, a spring 10 is arranged on one side of the guide plate 16, a multi-section telescopic rod 11 is arranged on one side of the spring 10, a guide rail 14 is fixedly connected in the groove 9 provided in the funnel shell 1, and an opening and closing device integrating electric and manual functions is provided so that the funnel can be used normally when the electric opening and closing device is damaged.

[0025] A flexible sealing layer 12 is provided on the outer side of the movable baffle 8, and a plurality of elastic blocks 13 are provided in the sealing layer 12. The elastic blocks 13 are arranged at a position close to the electromagnetic block 6, so that the sealing effect of the movable baffle 8 is better when it is in a closed state, and the funnel shell 1 will not be damaged when it is closed; the groove 9 opened in the funnel shell 1 is in the front position of the movable baffle 8, and the electromagnetic block 6 is arranged at the rear position of the movable baffle 8. The movable baffle 8 is metal, which is convenient for the electromagnetic block 6 to control the movable baffle 8; the pulley 15 and the guide rail 14 are slidably connected, and there are four guide rails 14 in total, which is convenient for the movable baffle 8 to move more smoothly; the multi-section telescopic rod 11 is fixedly connected to the manual pull ring 5, and the manual pull ring 5 and one side of the funnel shell 1 are provided with magnetic strips 17, so that when the electromagnetic block 6 controls the movable baffle 8, the manual pull ring 5 will not move.

[0026] Working process: During the operation of the equipment, the external power supply is energized. When the automatic flux funnel device for submerged arc welding is used, the funnel device is first placed in a suitable position, the electric switch 4 is started to put it in working state, the electromagnetic block 6 is energized, and since the movable baffle 8 is made of metal, the electromagnetic block 6 absorbs the movable baffle 8. At this time, the movable baffle 8 passes through the unloading through hole 7, and the flux accumulates on the top of the movable baffle 8. When unloading is required, the user turns off the electric switch 4, the electromagnetic block 6 loses its magnetism, and the elastic force of the spring 10 drives the movable baffle 8 to move forward. At the same time, the pulley 15 moves on the surface of the guide rail 14, so that the movable baffle 8 moves more smoothly. The multi-section telescopic rod 11 is in a retracted state, and the flux falls from the unloading through hole 7 to the flux leakage port 2 until it falls on the surface of the workpiece. The sealing layer 12 arranged on the outside of the baffle 8 makes the sealing effect better when the movable baffle 8 passes through the discharge through hole 7, and the flux is not easy to leak from the edge of the movable baffle 8. By setting a plurality of elastic blocks 13 on one side of the sealing layer 12, the movable baffle 8 will not cause damage to the funnel shell 1 when it is closed. When the electromagnetic block 6 fails, the user can hold the manual pull ring 5 and pull it outward. The distance between the magnetic strip 17 in the manual pull ring 5 and the magnetic strip 17 set on one side of the funnel shell 1 gradually increases until the magnetic attraction is lost. The manual pull ring 5 drives the multi-section telescopic rod 11 to extend, and the movable baffle 8 moves forward. At this time, the flux can be discharged from the flux leakage port 2. By setting an opening and closing device integrating electric and manual functions, the funnel can be used normally when the electric opening and closing device is damaged.
