Description

Technical Field

[0001] This invention relates to the field of flux-cored wire processing technology, and in particular to a flux-cored wire application device for hardfacing flux-cored wire processing. Background Technology

[0002] Flux-cored welding wire, also known as tubular welding wire, allows for the convenient design of various specialized welding materials by flexibly adjusting the type and proportion of flux additives. Because its alloy composition is easily controlled, many types of flux-cored welding wire cannot be smelted and rolled from solid welding wire.

[0003] When producing flux-cored welding wire, a thin metal strip needs to be rolled into a U-shaped cross-section, filled with flux powder, and then closed into a cylindrical shape. When the U-shaped steel strip closes into a cylinder, the internal space is suddenly compressed. If the flux powder filling density is insufficient or not fully compacted, the powder will be squeezed out from the open end under sudden pressure, causing flux powder overflow and ultimately resulting in uneven distribution of the flux core. Summary of the Invention

[0004] This invention proposes a flux-cored wire feeding device for hardfacing welding to address the aforementioned shortcomings in the prior art.

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

[0006] A flux loading device for hardfacing welding includes a feeding box and a conveyor belt fixed to the frame of the feeding box.

[0007] A powder filling mechanism, which is connected to a conveyor belt, includes a filling box fixed to the bottom of the conveyor belt, a U-shaped inlet on one side of the filling box, and a square outlet on the other side of the filling box;

[0008] A powder exhaust mechanism, which is connected to a powder filling mechanism, includes a motor, the output end of which is fixed with a rotating shaft, and one end of the rotating shaft is fixed with a rolling wheel;

[0009] The package anti-overflow mechanism is installed on one side of the powder filling mechanism and includes a movable frame. Two triangular blocks are rotatably connected to the bottom of the movable frame, and V-shaped rubber pads are fixed to the bottom of the two triangular blocks.

[0010] Furthermore, the powder filling mechanism also includes a chute opened on one side of the filling box, and a discharge control plate is sleeved inside the chute. The discharge control plate controls the square discharge port, thereby controlling the amount of material coming out with the workpiece. A U-shaped frame is fixed on one side of the filling box, and bolts are sleeved inside the U-shaped frame.

[0011] The workpiece is nested inside the U-shaped inlet and the square outlet.

[0012] Furthermore, the powder exhaust mechanism also includes a motor frame fixed to one side of the filling box, the motor is fixed inside the motor frame, the rotating shaft is rotatably connected inside the filling box, and the rolling wheel is sleeved inside the workpiece.

[0013] Furthermore, the package spill prevention mechanism also includes a reciprocating screw 1 rotatably connected to one side of the filling box, a bevel gear 1 fixed to one end of the reciprocating screw 1, a bevel gear 2 meshing on one side of the bevel gear 1, and the bevel gear 2 fixed to the outside of the rotating shaft;

[0014] The reciprocating screw is externally threaded with a movable plate, and a guide rod is internally fitted on the movable plate. One end of the guide rod is fixedly connected to the filling box.

[0015] Furthermore, the package spill prevention mechanism also includes a second movable plate fixed to the top of the first movable plate. A mounting frame is fixed to one side of the second movable plate. A second reciprocating screw is rotatably connected inside the mounting frame. A one-way gear is installed at the top of the second reciprocating screw. The movable frame is threaded onto the outside of the second reciprocating screw. A second guide rod is sleeved inside the movable frame. The second guide rod is fixed inside the mounting frame.

[0016] A workpiece stabilizing groove is fixed on one side of the filling box, and the workpiece is fitted inside the workpiece stabilizing groove.

[0017] A rack is fixed to the top of the workpiece stabilizing groove, and a rack is fixed to one side of the filling box. The racks one and two cooperate with a one-way gear.

[0018] Furthermore, the package spill prevention mechanism also includes support plates fixed on both sides of the movable frame. A top rod is sleeved inside the support plate, a connecting ring is fixed outside the top rod, a spring is fixed to the top of the connecting ring, and the top of the spring is fixedly connected to the support plate.

[0019] Furthermore, a controller is fixed to one side of the feeding box, and the controller is electrically connected to the conveyor belt and the motor.

[0020] Compared with existing technologies, the beneficial effects of this invention are:

[0021] 1. The present invention sets up a powder exhaust mechanism, in which a motor drives a rotating shaft to rotate a rolling wheel. During the rolling process, the powder is pressed into the workpiece, and the air inside the powder is discharged to enhance compactness and ensure uniform filling of the powder.

[0022] 2. This invention uses a wrapping anti-overflow mechanism with a V-shaped rubber pad to press the powder and guide it to gather from the edge to the center, creating a central bulge inside the workpiece. This reduces the amount of powder near the edge of the workpiece, thus preventing the powder from overflowing from the closed position when extruding into a cylindrical shape. This ensures the compactness of the powder and prevents uneven filling caused by powder overflow. At the same time, the V-shaped rubber pad covers the top of the powder, preventing the vibration generated when the workpiece moves from scattering or overflowing the compacted powder.

[0037] The powder filling mechanism 3 also includes a chute on one side of the filling box 31. A discharge control plate 33 is installed inside the chute.

[0043] A workpiece stabilizing groove 51 is fixed on one side of the filling box 31, and the workpiece 37 is fitted inside the workpiece stabilizing groove 51.

[0044] A rack 513 is fixed to the top of the workpiece stabilizing groove 51, and a rack 514 is fixed to one side of the filling box 31. The rack 513 and the rack 514 cooperate with the one-way gear 511.

[0045] The package spill prevention mechanism 5 also includes support plates 515 fixed on both sides of the movable frame 512. A top rod 516 is sleeved inside the support plate 515. A connecting ring 518 is fixed outside the top rod 516. A spring 517 is fixed to the top of the connecting ring 518. The top of the spring 517 is fixedly connected to the support plate 515.

[0046] A controller is fixed on one side of the feeding box 1, and the controller is electrically connected to the conveyor belt 2 and the motor 42.

[0047] Working principle:

[0048] The powder in the feeding hopper 1 falls onto the conveyor belt 2 through the lower inlet, and is then transported by the conveyor belt 2 to the filling hopper 31 for filling. Subsequently, the open workpiece 37 is pulled through the powder in the filling hopper 31 by other equipment, and the powder is filled into the workpiece 37. The motor 42 drives the rotating shaft 43 and the rolling wheel 44 to rotate. The rolling wheel 44 presses the powder into the workpiece 37 during rotation, expelling air from the powder and making it more compact. After the powder is filled, the workpiece 37 continues to move, passing through the square discharge port 36. During this process, the discharge control plate 33 inserted inside the workpiece 37 adjusts the following height of the powder, thereby precisely controlling the amount of powder in the workpiece 37.

[0049] The rotating shaft 43 drives the second bevel gear 54 to rotate, which in turn drives the first bevel gear 53 and the first reciprocating screw 52 to rotate. This causes the first moving plate 56 to move the second moving plate 57, the mounting bracket 58, the second reciprocating screw 510, the second guide rod 59, the moving frame 512, the one-way gear 511, the triangular block 519, and the V-shaped rubber pad 520 to one side. The moving speed is consistent with the traction speed of the workpiece 37, ensuring that the above structures move synchronously with the workpiece 37 and the powder. During the movement, the V-shaped rubber pad 520 covers the top of the powder to prevent the vibration generated by the movement of the workpiece 37 from scattering or dislodging the compressed powder.

[0050] During the movement, the one-way gear 511 meshes with rack 2 514, but the direction of rotation of the one-way gear 511 in this direction of movement cannot drive the reciprocating screw 2 510 to rotate. Therefore, the moving frame 512 remains at the bottom end of the reciprocating screw 2 510. When the one-way gear 511 disengages from rack 2 514 and moves a certain distance before meshing with rack 1 513, its direction of rotation can drive the reciprocating screw 2 510 to rotate, and the moving frame 512 then moves upward from the bottom end of the reciprocating screw 2 510. During the upward movement, the two triangular blocks 519 and the V-shaped rubber pad 520 are driven away from the workpiece 37, and the workpiece 37 then enters the closed top of the molding equipment, encapsulating the powder inside. During the upward movement, the compressed spring 517 is released, pushing the push rod 516 downward, causing the two triangular blocks 519 to rotate around the contact point with the moving frame 512, narrowing their bottom opening, avoiding friction and traction on the workpiece 37 during the upward movement, and facilitating the removal of the triangular blocks 519.

[0051] At this point, the moving plate 56 moves to the end of the reciprocating screw 52, ​​causing the moving plate 57, mounting bracket 58, reciprocating screw 510, guide rod 59, moving frame 512, one-way gear 511, triangular block 519, and V-shaped rubber pad 520 to reset. During the reset process, the one-way gear 511 meshes with rack 513 but cannot drive the reciprocating screw 510 to rotate, and the moving frame 512 remains at the top of the reciprocating screw 510. After moving a certain distance, it meshes with rack 514. In this direction of movement, the one-way gear 511 can drive the reciprocating screw 510 to rotate, causing the moving frame 512 to push the two triangular blocks 519 and V-shaped rubber pad 520 downwards. The two triangular blocks 519 are inserted into the top opening of the workpiece 37, and the bottom of the V-shaped rubber pad 520 contacts the powder. The moving frame 512 squeezes the two triangular blocks 519, causing them to open around the connection point. By narrowing the openings at the bottom of the two triangular blocks 519, the insertion of the triangular blocks 519 can be avoided by limiting the top of the workpiece 37. The powder is pressed using a V-shaped rubber pad, guiding it from the edge to the center, creating a central bulge inside the workpiece. This reduces the amount of powder near the edge, preventing powder from overflowing from the closed position when extruded into a cylindrical shape. This ensures the compactness of the powder and prevents uneven filling caused by powder overflow. Simultaneously, the V-shaped rubber pad covering the top of the powder prevents vibrations from moving the workpiece from scattering or overflowing the compacted powder.

[0052] As the V-shaped rubber pad 520 contacts the top of the powder, the moving plate 56 moves in the opposite direction from one end of the reciprocating screw 52, ​​so that the V-shaped rubber pad 520 and other structures continue to move synchronously with the workpiece 37 according to the above steps.

[0053] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
