Description

Technical Field

[0001] This application relates to flux-cored wire forming technology, and more particularly to a flux-cored wire forming device. Background Technology

[0002] Flux-cored welding wire is a welding material consisting of a metal sheath encasing welding flux (or alloy powder). During processing, a U-shaped roller bends a steel strip into an upward-opening U-shaped groove. Then, a powder feeding mechanism injects the flux powder into the groove through the opening. Finally, a closing roller closes the opening, causing the U-shaped groove to close into an O-shape encasing the flux core.

[0003] Existing flux-cored wire forming machines operate in factories for extended periods, accumulating a large amount of dust and dirt on the factory and equipment. After the steel strip is bent into a U-shaped groove, the dust and dirt from the factory and equipment easily fall into the groove. If not cleaned in time, it will cover the bottom of the flux powder, making the produced welding wire prone to flow interruption during welding, thus affecting the quality of the flux-cored wire. Utility Model Content

[0004] This application provides a flux-cored wire forming processing device to solve the problem that existing flux-cored wire forming machines are prone to dust accumulation in the U-shaped groove before injecting flux powder, which affects the quality of the flux core.

[0005] This application provides a flux-cored welding wire forming and processing device, including a powder feeding mechanism. The powder feeding mechanism is fixed between a U-shaped roll and a closed roll via a frame. Between the U-shaped roll and the closed roll is a U-shaped segment of a steel strip. A dust collector is installed on one side of the frame located on the U-shaped roll. The U-shaped segment of the steel strip passes through the dust collector. A high-pressure nozzle is fixed on the top wall of the dust collector in the opposite direction to the steel strip's travel path. The high-pressure nozzle performs airflow cleaning towards the groove of the U-shaped segment.

[0006] Optionally, a roller brush that extends into the groove of the U-shaped section and rotates is installed inside the dust collection cylinder.

[0007] Optionally, the roller brush has a plurality of radially arrayed ribs fixed on its rotating shaft, and the ribs can drive the roller brush to rotate by the air force of the high-pressure nozzle.

[0008] Optionally, the middle section of the dust collector is provided with a constriction section with a reduced inner diameter, and the airflow blown out by the high-pressure nozzle can be accelerated through the constriction section.

[0009] Optionally, the dust collector is fixed to the frame by a fixing bracket. The dust collector can move vertically along the frame by the fixing bracket and is locked by bolt one. The dust collector can also move horizontally along the fixing bracket and is locked by bolt two.

[0010] The flux-cored wire forming device provided in this application involves gradually bending a steel strip to form an upward-opening U-shaped segment. Before injecting flux powder into the groove of the U-shaped segment, the U-shaped segment passes through a dust collection cylinder. Compressed air is blown in the opposite direction into the groove of the U-shaped segment through a high-pressure nozzle fixed inside the dust collection cylinder, cleaning the groove along the steel strip. This prevents impurities from being trapped under the flux powder by the powder feeding mechanism, keeping the groove of the U-shaped segment clean and improving the quality of the flux core after powder injection.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions in the embodiments of this application are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are also within the scope of protection of this application.

[0021] like Figures 1-4 As shown, one embodiment of this application provides a flux-cored welding wire forming processing device, including a powder feeding mechanism 1. The powder feeding mechanism 1 is fixed between a U-shaped roller 4 and a closed roller 5 by a frame 3. Between the U-shaped roller 4 and the closed roller 5 is a U-shaped segment 14 of a steel strip. A dust collector 6 is installed on one side of the frame 3 located on the U-shaped roller 4. The U-shaped segment 14 of the steel strip passes through the dust collector 6. A high-pressure nozzle 7 is fixed on the top wall of the dust collector 6 in the opposite direction to the travel path of the steel strip. The high-pressure nozzle 7 performs airflow cleaning towards the groove of the U-shaped segment 14.

[0022] In operation, the steel strip is gradually bent into an upward-opening U-shaped groove by the U-shaped roller 4. After passing through the dust collector 6, the U-shaped section 14 of the steel strip is conveyed from below the powder feeding mechanism 1 to the closing roller 5. As the steel strip passes through the powder feeding mechanism 1, the powder in the upper hopper 2 is injected into the groove of the U-shaped section 14. Then, it is conveyed to the closing roller 5 to close the upper opening, making its cross-section O-shaped. The U-shaped section 14 entering the dust collector 6 is then sprayed with compressed air through the high-pressure nozzle 7, which cleans the groove along the U-shaped section 14 of the steel strip.

[0023] In this embodiment, the steel strip is gradually bent to form an upward-opening U-shaped segment 14. Before injecting the powder into the groove of the U-shaped segment 14, the U-shaped segment 14 passes through the dust collection cylinder 6. Compressed air is blown in the opposite direction into the groove of the U-shaped segment 14 through the high-pressure nozzle 7 fixed in the dust collection cylinder 6, and the airflow cleans the groove of the U-shaped segment 14 along the steel strip. This prevents the powder adding mechanism 1 from covering the lower end of the powder, keeps the groove of the U-shaped segment 14 clean, and improves the quality of the drug core after the powder is injected.

[0024] In one possible implementation, a roller brush 8 is installed inside the dust collection cylinder 6, which rotates within the groove of the U-shaped segment 14.

[0025] The roller brush 8 is driven by a motor to rotate and extends into the groove of the U-shaped section 14 to clean the stains attached to the steel strip.

[0026] like Figure 6As shown, in one possible implementation, a plurality of radially arrayed ribs 10 are fixed on the rotating shaft of the roller brush 8, and the ribs 10 can drive the roller brush 8 to rotate by the wind power of the high-pressure nozzle 7.

[0027] The roller brush 8 is located in front of the air outlet direction of the high-pressure nozzle 7. The compressed air blown by the high-pressure nozzle 7 pushes the rib plate 10 on the roller brush 8 along the groove of the U-shaped section 14, which enables the roller brush 8 to rotate by wind power without the need for a motor as a power input.

[0028] like Figure 5 As shown, in one possible implementation, the middle section of the dust collector 6 is provided with a constriction section 9 with a reduced inner diameter, and the airflow blown out by the high-pressure nozzle 7 can be accelerated through the constriction section 9.

[0029] The constriction section 9 can further accelerate the airflow blown out by the high-pressure nozzle 7, and the increased flow rate can enhance the peeling effect and cleaning effect on dirt and dust in the groove.

[0030] In one possible implementation, the dust collector 6 is fixed to the frame 3 by a fixing frame 11. The dust collector 6 can move vertically along the frame 3 by the fixing frame 11 and is locked by bolt 12. The dust collector 6 can also move horizontally along the fixing frame 11 and is locked by bolt 23.

[0031] The dust collector 6 is fixed to the frame 3 via a fixing frame 11. The fixing frame 11 is clamped and fixed to the upright of the frame 3, and can move up and down to adjust its height position and is locked by bolt 12. The dust collector 6 is clamped and fixed between the upper and lower clamping plates of the fixing frame 11, and can move laterally along the clamping plates of the fixing frame 11 to adjust its corresponding position with the steel strip and is locked by bolt 23.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
