Description

Technical Field

[0001] This utility model relates to the field of flux-cored welding wire processing technology, and in particular to a device for uniformly filling flux-cored welding wire powder. Background Technology

[0002] Flux-cored welding wire is a welding material in which flux powder is filled inside a metal outer sheath (U-shaped or O-shaped substrate), and the uniformity of the filling directly affects the welding quality.

[0003] Traditional single-stage filling can easily lead to loose powder or local voids, and lacks compaction and shape adaptation functions. Traditional filling methods have problems such as uneven powder distribution, low filling density, and poor compaction effect, resulting in unstable welding wire performance. Utility Model Content

[0004] The present invention addresses the problem of providing a uniform filling device for flux-cored welding wire powder, which solves the technical problems of unstable welding wire performance caused by the traditional single-stage filling method, which is prone to powder loosening or local voids and lacks compaction and shape adaptation functions. The traditional filling method has problems such as uneven powder distribution, low filling density and poor compaction effect.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A device for uniformly filling flux-cored welding wire powder includes a frame, a first filling mechanism, a second filling mechanism, and a third filling mechanism. The first filling mechanism, the second filling mechanism, and the third filling mechanism are sequentially installed on the frame. Each of the first filling mechanism, the second filling mechanism, and the third filling mechanism includes a conveying cylinder. A spiral shaft is rotatably installed inside the conveying cylinder. A feed pipe is installed on the top side of one end of the conveying cylinder and is connected to a hopper. A discharge pipe is installed on the bottom side of the other end of the conveying cylinder. A filling pipe is installed on the bottom side of the discharge pipe. The height of the filling pipes of the first filling mechanism, the second filling mechanism, and the third filling mechanism increases progressively along the moving direction of the flux-cored welding wire. A compaction component is installed on the side wall of the filling pipe.

[0007] Preferably, a motor is installed at the end of the conveying cylinder, and the output end of the motor is connected to the screw shaft.

[0008] Preferably, the compaction mechanism includes a mounting plate installed on the side wall of the filling pipe, and a pneumatic cylinder is mounted on the mounting plate, with the telescopic end of the pneumatic cylinder connected to the lifting plate.

[0009] Preferably, a baffle plate is installed on the bottom side of the lifting plate near the end of the filling tube.

[0010] Preferably, the other end of the lifting plate is provided with a wheel groove, and a compaction wheel is installed in the wheel groove.

[0011] Preferably, the outer side of the compaction wheel of the third filling mechanism is provided with an arc-shaped groove.

[0012] The beneficial effects of this utility model are: through the stepped design of the three-stage filling mechanism, the height of the filling tube increases step by step, and the core material is filled to 1 / 3, 2 / 3 and full in stages, avoiding uneven powder distribution or pile-up gaps caused by one-time filling, and significantly improving the uniformity of filling density.

[0013] The compaction component integrates scraping and compaction functions. The baffle plate scrapes away excess powder, and the compaction wheel compacts simultaneously, reducing manual intervention. The arc-shaped groove pre-forming design allows the third-stage compaction wheel to press the top of the core material into an arc shape through the arc groove, perfectly matching the subsequent U-shaped substrate rolling process, reducing material waste and avoiding filling defects caused by shape mismatch.

[0019] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Specific implementation examples are given below.

[0021] See Figures 1-3A uniform filling device for flux-cored welding wire powder includes a frame 1, a first filling mechanism 2, a second filling mechanism 3, and a third filling mechanism 4. The first filling mechanism 2, the second filling mechanism 3, and the third filling mechanism 4 are sequentially installed on the frame 1. Each of the first filling mechanism 2, the second filling mechanism 3, and the third filling mechanism 4 includes a conveying cylinder 5. A spiral shaft 9 is rotatably installed inside the conveying cylinder 5. A feed pipe 6 is installed on the top side of one end of the conveying cylinder 5 and is connected to a hopper 7. A discharge pipe 10 is installed on the bottom side of the other end of the conveying cylinder 5. A filling pipe 11 is installed on the bottom side of the discharge pipe 10. The height of the filling pipe 11 of the first filling mechanism 2, the second filling mechanism 3, and the third filling mechanism 4 increases gradually along the moving direction of the flux-cored welding wire. A compaction component is installed on the side wall of the filling pipe 11.

[0022] A motor 8 is installed at the end of the conveying cylinder 5. The output end of the motor 8 is connected to the screw shaft 9. The motor 8 drives the screw shaft 9 to convey powder. Combined with the independent hopper 7, feed pipe 6, and discharge pipe 10, the powder flow rate can be controlled, ensuring that the filling amount of each stage is accurately matched with the preset ratio, reducing the risk of overfilling or underfilling.

[0023] The compaction mechanism includes a mounting plate 12 installed on the side wall of the filling tube 11. A pneumatic cylinder 13 is installed on the mounting plate 12, and the telescopic end of the pneumatic cylinder 13 is connected to a lifting plate 14. A baffle plate 15 is installed on the bottom side of the lifting plate 14 near the end of the filling tube 11. A wheel groove 16 is opened at the other end of the lifting plate 14, and a compaction wheel 17 is installed in the wheel groove 16. An arc-shaped groove 18 is opened on the outer side of the compaction wheel 17 of the third filling mechanism 4. The compaction component integrates the functions of scraping and compaction. The baffle plate 15 scrapes off excess powder, and the compaction wheel 17 compacts simultaneously, reducing manual intervention. The arc-shaped groove 18 is pre-formed. The third-stage compaction wheel 17 presses the top of the core material into an arc shape through the arc-shaped groove 18, perfectly matching the subsequent U-shaped substrate rolling process, reducing material waste and avoiding filling defects caused by shape mismatch.

[0024] Through the stepped design of the three-stage filling mechanism, the height of the filling tube 11 increases step by step, filling the core material to 1 / 3, 2 / 3 and full volume in stages, avoiding uneven powder distribution or pile-up gaps caused by one-time filling, and significantly improving the uniformity of filling density.

[0025] When the U-shaped welding wire substrate passes under the first filling mechanism 2, the second filling mechanism 3, and the third filling mechanism 4, the motor 8 drives the spiral shaft 9 to rotate. At this time, the flux-cored material enters the conveying cylinder 5 from the hopper 7 and the feed pipe 6, and is filled into the U-shaped welding wire substrate through the discharge pipe 10 and the filling pipe 11. The first filling mechanism 2 fills the U-shaped welding wire substrate with flux-cored material to one-third, the second filling mechanism 3 fills the U-shaped welding wire substrate with flux-cored material to two-thirds, and the third filling mechanism 4 fills the U-shaped welding wire substrate completely with flux-cored material. After filling, the lifting plate 14 is raised and lowered by the pneumatic cylinder 13 to adjust the height of the baffle plate 15 and the compaction wheel 17. The baffle plate 15 scrapes the flux-cored material in the U-shaped welding wire substrate flat, and the compaction wheel 17 compacts it. The arc groove 18 of the compaction wheel 17 compacts the top of the filled flux-cored material in the U-shaped welding wire substrate into an arc shape, which is convenient for subsequent processing of the U-shaped welding wire substrate into a circle, avoiding the filling of the internal flux-cored material and preventing waste.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
