Description

Technical Field

[0001] The invention relates to the technical field of flux-cored welding wire processing, and in particular to a flux-cored welding wire processing device. Background Art

[0002] Flux-cored welding wire is made of low-carbon steel or low-alloy steel with good plasticity. Its manufacturing method is to first roll the steel strip into a U-shaped cross-section, then add the welding powder prepared according to the dosage into the U-shaped steel strip, roll it tightly with a rolling mill, and finally draw it. Flux-cored welding wire can be easily designed into welding materials for various purposes (wear-resistant, high-strength, heat-resistant, corrosion-resistant, low-temperature resistant, etc.) by adjusting the type and proportion of the alloy composition of the welding powder. Because its alloy composition can be flexibly and conveniently adjusted, many varieties of flux-cored welding wire cannot be smelted and rolled by solid welding wire.

[0003] Patent CN118180694A discloses a flux-cored welding wire forming processing device and its use method, including a bottom plate, a strip guide rail is fixedly installed on the upper surface of the bottom plate, a U-shaped guide groove is penetrated at the end of the strip guide rail, and a conical drawing tube is fixedly installed at the discharge end of the strip guide rail. The invention drives the fixed sleeve installed on the transmission shaft to rotate by a driving motor, so that the multiple rotating rods installed on the outer surface of the fixed sleeve can swing evenly, so that the knocking block fixedly installed at the end of the rotating rod can knock on the upper and lower sides of the C-shaped plate when rotating. Since the hopper is installed on the support rod through an elastic support mechanism, the C-shaped plate can drive the hopper to vibrate up and down when being knocked, so that the flux in the hopper can fall into the U-shaped steel belt through the two discharge pipes, avoiding the agglomeration of flux, making it difficult to discharge, and causing uneven filling of flux.

[0004] In the flux-cored wire forming processing device in the above-mentioned patent, during the process of applying flux, the rotating rod is controlled to rotate to knock the C-type plate up and down to drive the hopper to vibrate up and down, so as to realize the discharge of the two discharge pipes. However, as the mass of the hopper changes during discharge, its vibration amplitude will also change, resulting in uneven discharge; and when the flux placed in the steel belt is driven to the bottom of the two pressing wheels by the movement of the steel belt, although it can be pressed, the flux will be dispersed to both sides due to the squeezing force of the pressing wheels during pressing, especially when the unit flux filling mass is large, this effect will be more obvious, and the pressed flux will be squeezed by the flux being pressed at the edge, and will crack or disperse to varying degrees, resulting in uneven flux filling and poor flux core forming quality.

[0021] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0022] Embodiment 1, as Figure 1-Figure 9As shown, a drug feeding device for flux-cored welding wire processing comprises a drug feeding seat 1, a U-shaped guide groove 11 is provided at the front side of the drug feeding seat 1, a limit strip 12 is fixedly connected to the right side of the U-shaped guide groove 11, a shaping section 2 is slidably connected in the U-shaped guide groove 11, a shaping drug groove and a drug delivery cavity are provided at the bottom of the shaping section 2, a displacement sensor 21 is fixedly connected to the upper end of the shaping section 2, a drug supply tube 22 is fixedly plugged at the rear side of the top of the drug delivery cavity and a pressure relief cavity is provided at the front side of the top, a pressure relief block 23 is slidably connected to the bottom of the pressure relief cavity, and sealing baffles 4 are provided on the left and right sides of the shaping drug groove respectively; There is a partition in the middle of the drug delivery cavity and is rotatably connected to a spiral conveying rod 3. A driving component is arranged on the right side of the partition. A spiral spring 34 is arranged between the driving component and the spiral conveying rod 3. An adjusting component for adjusting the up and down movement of the sealing partition 4 and the left and right movement of the forming section 2 is arranged on the right side of the driving component. A drug storage tank 6 is fixedly connected to the top of the upper drug seat 1. The bottom of the drug storage tank 6 is contracted to form a drug outlet connected to the drug supply pipe 22, and a dredging component is arranged in the drug storage tank 6.

[0023] A U-shaped chute for the steel belt to pass through is provided on the periphery of the bottom of the shaping section 2, and the shaping medicine chute can be combined with the steel belt to form a columnar chamber.

[0024] When applying medicine, the steel strip is passed through the bottom of the shaping section 2 along the U-shaped guide groove 11 by the external conveying mechanism and outputted outwards, and then the steel strip is pressed into a circle by the pressing mechanism arranged on the left side of the medicine applying seat 1, and the driving component is controlled to operate, and the driving component drives the dredging component to continuously dredge the solder in the medicine storage tank 6 to avoid the solder from arching and agglomeration, and ensure its smooth output, thereby improving the subsequent pressing and forming speed, and the synchronous driving component drives the volute spring 34 to rotate the spiral conveying rod 3, and as the spiral conveying rod 3 rotates, the solder in the medicine storage tank 6 is moved under the influence of gravity and dredging. When the component is toggled, the drug falls into the drug delivery cavity through the drug outlet and the drug supply tube 22, and is continuously delivered into the shaped drug groove as the spiral conveying rod 3 rotates. Subsequently, as the solder is continuously delivered to the shaped drug groove, it is hindered by the sealing partition 4 on the left side, and the solder is continuously accumulated and compacted in the shaped drug groove. Subsequently, when the drug delivery cavity is also filled with solder, the spiral conveying rod 3 has too great a resistance to rotation and delivery and cannot rotate. The volute spring 34 is automatically deformed to make the adjustment component operate to control the sealing partition 4 on the right side to move downward, cutting the solder into fixed specifications. It can be combined with the steel strip to form a columnar chamber, so the solder is prefabricated into a cylindrical shape, which is convenient for subsequent wrapping with the steel strip. When the steel strip is rolled into a circular shape to wrap the solder, the solder is not easy to loosen due to the compaction effect. Subsequently, as the driving component continues to operate, the sealing partition 4 on the left side automatically moves up to open the left port of the shaping tank. When the synchronous adjustment component is in operation, the limit strip 12 is squeezed, thereby driving the shaping section 2 to move to the left as a whole to push this section of solder to the previous section of solder to dock regularly, thereby avoiding unevenness and cracking during solder pressing through closed compaction molding. The loose problem is solved and the quality of the flux core is improved. During this period, the displacement sensor 21 monitors the moving distance of the shaping section 2. When the moving distance just reaches the distance where this section of flux is connected with the previous section of flux, the external conveying mechanism drives the steel belt to shift and switch to convey a new flux application section. At the same time, the pressed flux is moved to the position of the previous section of flux, and then the pressure relief block 23 is controlled to move up automatically to increase the volume of the conveying chamber, thereby reducing the rotation resistance of the spiral conveying rod 3. The volute spring 34 can drive each part to quickly and automatically reset, so that the flux application and molding operation can be carried out again.

[0025] Embodiment 2, as Figure 2-Figure 4 As shown, based on the above embodiment, a driving component structure is provided: The driving assembly includes a transmission disc 32 rotatably connected to the right wall of the partition, the transmission disc 32 is fixedly connected to the spiral conveying rod 3, the inner wall of the transmission disc 32 is rotatably connected to a guide sleeve 33, and a spiral spring 34 is fixedly connected between the guide sleeve 33 and the transmission disc 32; A bracket is provided at the top of the U-shaped guide groove 11, and a driving shaft 5 is rotatably connected to the bracket. The driving shaft 5 is driven by a motor installed on the right wall of the bracket. A transmission sleeve 26 movably connected to the driving shaft 5 is rotatably connected to the upper end of the shaping section 2, and a transmission belt is movably connected between the transmission sleeve 26 and the guide sleeve 33.

[0026] The driving shaft 5 drives the transmission sleeve 26 to rotate, and the transmission sleeve 26 drives the guide sleeve 33 to rotate through the transmission belt, and the guide sleeve 33 drives the transmission plate 32 through the volute spring 34 to rotate the spiral conveying rod 3, so as to convey the solder. When in use, the elastic force of the volute spring 34 is large enough to avoid the premature deformation of the volute spring 34 before the solder is compacted to drive the adjustment component to operate; Since the transmission sleeve 26 is movably connected to the driving shaft 5, when the shaping section 2 moves to the left to push the compacted solder, the driving shaft 5 can still stably drive the guide sleeve 33 to rotate, so that after the shaping medicine groove and the medicine delivery cavity are filled with solder and the spiral conveying rod 3 cannot rotate, the spiral spring 34 can automatically deform to allow the adjustment component to control the two sealing partitions 4 to cut and release the solder.

[0027] Embodiment three, as Figure 2 and Figure 7-Figure 8 As shown, based on the above embodiment, a dredging component structure is provided: The dredging component includes an elastic gear sleeve 61 which is slidably sleeved on the bottom of the medicine storage tank 6, a T-shaped dredging rod 62 is fixedly connected to the inner wall of the elastic gear sleeve 61, a movable groove adapted to the elastic gear sleeve 61 is provided on the outer wall of the bottom of the medicine storage tank 6, the T-shaped dredging rod 62 is slidably inserted into the upper wall of the inner cavity of the medicine storage tank 6, a linearly arranged multi-row dredging cross bar 63 is fixedly connected to the periphery of the T-shaped dredging rod 62, and a missing gear 51 which can mesh with the elastic gear sleeve 61 is fixedly sleeved on the left end of the driving shaft 5.

[0028] While the driving assembly drives the spiral conveying rod 3 to convey the solder, the driving shaft 5 drives the missing gear 51 to move the elastic gear sleeve 61 upward, and the elastic gear sleeve 61 drives the T-shaped dredging rod 62 to move each dredging cross bar 63 upward. When the missing gear 51 disengages from the elastic gear sleeve 61, the elastic gear sleeve 61 drives the T-shaped dredging rod 62 and each dredging cross bar 63 to automatically move downward and reset under the action of its own elastic force. As the driving shaft 5 drives the missing gear 51 to continue to rotate, the T-shaped dredging rod 62 drives each dredging cross bar 63 to move back and forth up and down to dredge the solder in the medicine storage tank 6, avoid arching and agglomeration, and ensure smooth solder feeding.

[0029] Embodiment 4, as Figure 2 and Fig. 9 As shown, based on the above embodiment, a drug supply tube 22 structure is provided: The top edge of the medicine supply tube 22 is extended to form a sealing portion for movably contacting with the medicine outlet.

[0030] When the solder is compacted in the shaping tank and pushed to dock with the front solder, the sealing portion at the top of the supply pipe 22 can seal the outlet at the bottom of the storage tank 6 to temporarily interrupt the supply and avoid leakage.

[0031] Embodiment 5, as Figure 3-Figure 7 As shown, based on the above embodiment, a regulating component structure is provided: The adjustment component includes a crank tube 42 rotatably connected to the left and right sides of the upper end of the shaping section 2, an L-shaped slide groove 41 is provided on the sealing partition 4, the crank tube 42 is movably connected with the L-shaped slide groove 41, a guide groove 1 43 and a guide groove 2 44 are respectively provided in the crank tubes 42 on the left and right sides, an L-shaped guide rod 45 is movably inserted between the crank tubes 42 on both sides, and two pin protrusions 1 46 are provided on the L-shaped guide rod 45, which are movably connected with the guide groove 1 43 and the guide groove 2 44, respectively, and the L-shaped guide rod 45 is fixedly connected to the limit bar 12; The inner wall of the guide sleeve 33 is slidably engaged with a core sleeve 47 movably sleeved on the spiral conveying rod 3. The core sleeve 47 is fixedly connected to the L-shaped guide rod 45. The inner wall of the core sleeve 47 is provided with a pin protrusion 48. The outer periphery of the spiral conveying rod 3 is provided with a spiral groove 31 movably engaged with the pin protrusion 48.

[0032] Furthermore, the guide groove 1 43 is composed of a connected combination of straight grooves 1 on both sides and an arc groove 1 in the middle, and the guide groove 2 44 is composed of a connected combination of an arc groove 2 on the left side and a straight groove 2 on the right side.

[0033] Initially, the pin protrusion 1 46 on the left side is movably engaged with the straight groove 1 on the left side of the guide groove 1 43, and the pin protrusion 1 46 on the right side is movably engaged with the arc groove 2 on the left side of the guide groove 2 44. When the shaped medicine groove and the conveying chamber are filled with solder, the spiral conveying rod 3 cannot rotate due to excessive resistance, and the transmission plate 32 cannot rotate either. The guide sleeve 33 continues to rotate to compress the spiral spring 34, and the synchronous guide sleeve 33 drives the core sleeve 47 to rotate at the same time. Since the core sleeve 47 is slidably engaged with the inner wall of the guide sleeve 33, when the core sleeve 47 rotates, the pin protrusion 2 48 is driven by the spiral groove 31 to move the core sleeve 47 to the right, and the core sleeve 47 thereby drives the L-shaped guide rod 45 to move to the right. The L-shaped guide rod 45 drives the pin protrusion 1 46 on the right side to squeeze the arc groove 2 on the left side of the guide groove 2 44, thereby driving the crank tube 42 to deflect backward, squeezing the L-shaped slide groove 41 to move the sealing partition 4 on the right side downward, cutting off the compacted solder, and the left The pin convex 146 on the left side moves along the straight groove 1 on the left side of the guide groove 143, and the crank tube 42 on the left side still drives the corresponding sealing partition 4 to be fixed, so as to ensure that when the welding powder is cut off, the left end of the welding powder will not be depressurized and cause the welding powder to move and deform. When the welding powder is cut off, the pin convex 146 on the right side is clamped by the arc groove 2 on the left side of the guide groove 144 to the straight groove 2 on the right side, and the pin convex 146 on the left side is clamped by the straight groove 1 on the left side of the guide groove 143 to the arc groove 1 in the middle, thereby driving the crank tube 42 on the left side to deflect upward, squeezing the L-shaped slide groove 41 to drive the sealing partition 4 on the left side to move upward, so as to release the cut welding powder. As the L-shaped guide rod 45 continues to move right, the pin convex 146 on the left side is clamped by the arc groove 1 in the middle of the guide groove 143 to the straight groove 1 on the right side, and the pin convex 146 on the right side continues to move along the straight groove 2 on the right side of the guide groove 144, and the two sealing partitions 4 maintain a stable left-open and right-closed state. When the L-shaped guide rod 45 moves to the right, it is limited by the limiting strip 12. When the L-shaped guide rod 45 moves to the right on the shaping section 2, it relatively pushes the shaping section 2 (part of the shaping section 2 can be made of a light and hard carbon fiber material to reduce the weight and facilitate movement) to move to the left, so that the sealing partition 4 on the right side is used to push the flux to dock with the flux in the front section. This method of applying flux not only avoids uneven flux, but also avoids the occurrence of loose cracking on both sides when the flux is pressed.

[0034] Embodiment six, as Figure 2-Figure 3 As shown, based on the above embodiments: The left and right sealing partitions 4 are both slidably plugged into the shaping section 2 and slidably connected to the front wall of the upper medicine seat 1 , and can both seal one side of the corresponding shaping medicine groove.

[0035] Through this design, when the crank tube 42 deflects and drives the sealing baffle 4 to move up and down, it is ensured that the sealing baffle 4 is under balanced force and moves smoothly; when the left sealing baffle 4 seals the left side of the shaping medicine groove, the accumulated solder can be reliably compacted and will not leak; when the right sealing baffle 4 seals the right side of the shaping medicine groove, it is ensured that the solder will not leak when being pushed.

[0036] Embodiment seven, as Figure 3 As shown, based on the above embodiments: The displacement sensor 21 is movably sleeved on the L-shaped guide rod 45 and is used to monitor the moving distance of the L-shaped guide rod 45 .

[0037] When the L-shaped guide rod 45 moves to the right and pushes the limit bar 12 to make the shaping section 2 move to the left and push the flux to connect with the previous section of flux, the L-shaped guide rod 45 moves relatively through the displacement sensor 21, thereby monitoring the movement distance of the shaping section 2. When the movement distance just reaches the distance where this section of flux connects with the previous section of flux, the displacement sensor 21 can feedback control the external conveying mechanism to drive the steel belt to shift and switch to convey a new section of flux, and at the same time move the pressed flux to the position of the previous section of flux.

[0038] Embodiment eight, as Fig. 9 As shown, based on the above embodiment, a pressure relief block 23 control structure is provided: A supporting mesh plate 24 is fixedly connected to the top of the pressure relief chamber, an electric push rod 25 is fixedly connected between the supporting mesh plate 24 and the pressure relief block 23 , and the electric push rod 25 is electrically connected to the displacement sensor 21 .

[0039] When the displacement sensor 21 feedback controls the external conveying mechanism to drive the steel belt to shift and switch to convey a new soldering section, and at the same time makes the pressed solder move to the position of the previous solder section, the electric push rod 25 automatically controls the electric push rod 25 to contract and drive the pressure relief block 23 to move upward according to the feedback signal of the displacement sensor 21, so as to increase the volume of the conveying chamber. Under the action of the elastic force accumulated by the compression of the vortex spring 34, the vortex spring 34 releases the elastic potential energy, and at the same time drives the spiral conveying rod 3 to squeeze the accumulated solder into the pressure relief block 23. The vortex spring 34 automatically resets relative to the guide sleeve 33, thereby driving the adjustment component and the forming section 2 to partially reset, so as to perform the soldering and forming operation again.

[0040] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
