Description

Technical Field

[0001] This utility model belongs to the field of welding wire processing technology, and more specifically, it relates to a continuous preparation device for high-strength flux-cored welding wire for high-temperature and high-pressure pipeline welding. Background Technology

[0002] The continuous welding wire preparation device is an integrated and automated production equipment specifically designed to produce high-strength flux-cored welding wires that meet the welding requirements of high-temperature and high-pressure pipelines. By integrating processes such as steel strip processing, flux filling, forming welding, and drawing and diameter reduction, it achieves uninterrupted production of welding wires. Targeting the welding needs of high-temperature and high-pressure pipelines, it adopts high-strength steel base materials and specific flux formulations, and is widely used in high-temperature, high-pressure, and highly corrosive industrial fields such as petroleum, chemical, power, and aerospace.

[0003] In the prior art, patent application CN217193152U discloses a "Wire Feeder for High-Strength Cored Wire with Over 690MPa to Prevent Deviation"; it includes a base plate, a fixed plate fixedly connected to the top of the base plate, a winding wheel movably connected to the inside of the fixed plate via a pin, a support plate fixedly connected to the top of the base plate, a fixed box fixedly connected to one side of the support plate, a spring fixedly connected to the inner wall of the fixed box, a movable plate fixedly connected to the other end of the spring, a movable rod fixedly connected to the other side of the movable plate, the other end of the movable rod extending to the outside of the fixed box and movably connected to a buffer wheel via a pin, and a support column fixedly connected to the top of the base plate. This utility model solves the problem that existing wire feeders lack a moving buffer effect, and when the wire feeding process is suddenly hindered by resistance, causing the wire feeding to jam and the tension of the metal wire to suddenly increase, it will lead to machine damage, and it cannot prevent the metal wire from deviating, which is not conducive to human use.

[0004] The aforementioned "wire feeder for high-strength flux-cored wire with anti-deviation over 690MPa" still has some drawbacks. For example, when processing high-strength flux-cored welding wire for high-temperature and high-pressure pipeline welding, compared to the processing of ordinary welding wire, if the particle size distribution is uneven, it is easy to cause blockage of the wire feeding mechanism. At the same time, uneven particles will affect the stability of the electric arc.

[0005] To address these issues, a continuous preparation device for high-strength flux-cored welding wire used in high-temperature and high-pressure pipeline welding is proposed. Utility Model Content

This solves the problem mentioned in the background art that, compared to the processing of ordinary welding wire, uneven particle size distribution can easily cause blockage of the wire feeding mechanism, and uneven particles can affect the stability of the electric arc.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a continuous preparation device for high-strength flux-cored welding wire for high-temperature and high-pressure pipeline welding, comprising a top feed cylinder, a bottom feed cylinder fixedly connected to the bottom of the top feed cylinder, a feeder fixedly connected to the bottom of the bottom feed cylinder, a feed pipe fixedly connected to one end of the feeder, a top support frame fixedly connected to the top of the top feed cylinder, a top motor fixedly connected to the top of the top support frame, a top transmission rod fixedly connected to the output shaft of the top motor, a transmission inner frame fixedly connected to one end of the top transmission rod, an inner stirring blade fixedly connected to the inner side of the transmission inner frame, an inner inclined mesh fixedly connected to the inner side of the top feed cylinder, a side discharge trough opened on the inner side of the bottom feed cylinder, a side discharge box fixedly connected to one side of the bottom feed cylinder, a bottom discharge box fixedly connected to the bottom of the side discharge box, a grinding box fixedly connected to the bottom of the bottom discharge box, and a bottom discharge box fixedly connected to the bottom of the grinding box.

[0013] Compared with the prior art, this utility model provides a continuous preparation device for high-strength flux-cored welding wire for high-temperature and high-pressure pipeline welding, which has the following beneficial effects:

[0014] 1) The bottom stirring brush continuously contacts the surface of the inner inclined screen, sweeping away smaller powder particles from the inner inclined screen surface, while larger powder particles remain on the surface of the inner inclined screen, improving the powder filtration effect.

All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a continuous preparation device for high-strength flux-cored welding wire for high-temperature and high-pressure pipeline welding, comprising a top feed cylinder 1, a bottom feed cylinder 2 fixedly connected to the bottom of the top feed cylinder 1, a feeder 3 fixedly connected to the bottom of the bottom feed cylinder 2, a feed pipe 4 fixedly connected to one end of the feeder 3, a top support frame 501 fixedly connected to the top of the top feed cylinder 1, a top motor 502 fixedly connected to the top of the top support frame 501, and a top transmission rod 503 fixedly connected to the output shaft of the top motor 502. One end of the rod 503 is fixedly connected to the inner transmission frame 504. The inner side of the inner transmission frame 504 is fixedly connected to the inner stirring blade 505. The inner side of the top feed cylinder 1 is fixedly connected to the inner inclined mesh 601. The inner side of the bottom feed cylinder 2 is provided with a side discharge chute 602. One side of the bottom feed cylinder 2 is fixedly connected to the side discharge box 603. The bottom of the side discharge box 603 is fixedly connected to the bottom discharge box 604. The bottom of the bottom discharge box 604 is fixedly connected to the grinding box 605. The bottom of the grinding box 605 is fixedly connected to the bottom discharge box 606.

[0026] It should be noted that by activating the top drive rod 503, the inner drive frame 504 is driven to rotate. The rotating inner drive frame 504 will drive multiple inner stirring blades 505 to stir the powder, so that the smaller powder particles fall evenly through the inner inclined screen 601 into the bottom feed cylinder 2. The bottom stirring brush 507 continuously contacts the surface of the inner inclined screen 601 to clean the smaller powder particles on the surface of the inner inclined screen 601, while the larger powder particles will remain on the surface of the inner inclined screen 601, thus improving the filtration effect of the powder.

[0027] In an optional embodiment, side cleaning brushes 506 are fixedly connected to both sides of the transmission inner frame 504.

[0028] It should be noted that the continuously rotating transmission inner frame 504 will drive the side cleaning brush 506 to clean along the inner wall of the top feed cylinder 1, cleaning the accumulated powder residue on the inner wall of the top feed cylinder 1, reducing the workload of subsequent operators.

[0032] It should be noted that, by having the parallel auxiliary roller 6011 and the main roller 6010 rotate in opposite directions, the powder is crushed by the continuously rotating main roller 6010 and auxiliary roller 6011 as it passes between the main roller 6010 and the auxiliary roller 6011.

[0033] In an optional embodiment: a side extension rod 6021 is fixedly connected to one side of the third helical gear disk 6019, a third bearing disk 6022 is fixedly connected to one end of the side extension rod 6021, and one side of the third bearing disk 6022 is fixedly connected to the inner side of the right sealing plate 608.

[0034] It should be noted that when the inner fixing rod 6018 rotates, it will drive the side extension rod 6021 to rotate. The No. 3 bearing disc 6022 at one end of the side extension rod 6021 is movably supported on the inner side of the right sealing plate 608, which improves the stability of the inner fixing rod 6018 rotating along the inside of the right sealing plate 608.

[0035] In an optional embodiment: a side support rod 6015 is fixedly connected to one side of the first helical toothed disc 6014, a second bearing disc 6016 is fixedly connected to one end of the side support rod 6015, one side of the second bearing disc 6016 is fixedly connected to the inner side of the right sealing plate 608, one end of the auxiliary rolling roller 6011 is fixedly connected to a first bearing disc 6012, and one side of the first bearing disc 6012 is fixedly connected to the inner side of the left sealing plate 607.

[0036] It should be noted that when the auxiliary roller 6011 rotates, it is movably supported on the inner side of the left sealing plate 607 through the first bearing disc 6012, which improves the rotation stability of the auxiliary roller 6011. At the same time, when the main roller 6010 rotates, it is movably supported on the inner side of the right sealing plate 608 through the second bearing disc 6016 at one end of the side connecting rod 6013, which improves the rotation stability of the main roller 6010.

[0037] The specific usage and function of this embodiment: During the daily operation of the continuous preparation device for high-strength flux-cored welding wire for high-temperature and high-pressure pipeline welding, when the external flux powder is first added to the top feed cylinder 1, the flux powder ash enters the bottom feed cylinder 2 along the top feed cylinder 1. Before entering the bottom feed cylinder 2, it will accumulate on the surface of the inner inclined mesh 601. At this time, by activating the top drive rod 503, the top drive rod 503 drives the inner drive frame 504 to rotate. The rotating inner drive frame 504 will drive multiple inner stirring blades 505 to feed the flux powder. The stirring action evenly distributes smaller powder particles through the inner inclined screen 601 into the bottom feed cylinder 2. The bottom stirring brush 507 continuously contacts the surface of the inner inclined screen 601, cleaning the smaller powder particles from the surface of the inner inclined screen 601. Larger powder particles remain on the surface of the inner inclined screen 601, improving the filtration effect of the powder. Through portable filtration of the powder, the continuously moving inner stirring blade 505 and bottom stirring brush 507 improve the efficiency of powder filtration and the efficiency of continuous preparation of flux-cored welding wire.

[0038] Both the inner inclined mesh 601 and the side discharge chute 602 are inclined. Larger particles of medicine powder will enter the side discharge chute 602 along the inclined inner mesh 601, and then be fed into the inner side of the side discharge box 603 along the side discharge chute 602. The medicine powder will continuously fall into the bottom discharge box 604 along the side discharge box 603, and then into the grinding box 605. By starting the side motor 609, the grinding box is further emptied. The main roller 6010 is driven to rotate by a side motor 609. The rotation of the main roller 6010 drives the first helical gear disc 6014 to rotate. Through the meshing of the first helical gear disc 6014 with the second helical gear disc 6017, the rotation of the first helical gear disc 6014 drives the inner fixed rod 6018 on one side of the second helical gear disc 6017 to rotate. The continuously rotating inner fixed rod 6018 then drives the third helical gear disc 6019 to rotate. By utilizing the meshing of the No. 3 helical toothed disc 6019 and the No. 4 helical toothed disc 6020, when the No. 3 helical toothed disc 6019 rotates, it will drive the auxiliary grinding roller 6011 on one side of the No. 4 helical toothed disc 6020 to rotate synchronously. At this time, when the side motor 609 drives the main grinding roller 6010 to rotate, it will synchronously drive the auxiliary grinding roller 6011 to rotate in the opposite direction along one side of the main grinding roller 6010. Through the parallel auxiliary grinding roller 6011 and the main grinding roller 6010 rotating in the opposite direction, when the powder passes between the main grinding roller 6010 and the auxiliary grinding roller 6011, the continuously rotating main grinding roller 6010 and the auxiliary grinding roller 6011 crush the powder, breaking down larger particles. The crushed powder will enter the feeder 3 along the bottom discharge box 606, which improves the efficiency of preparing the core welding wire from the powder, improves the uniformity of the powder particles, and improves the stability of subsequent welding wire processing.

[0039] The contents not described in detail in this specification are existing technologies known to those skilled in the art and are not key to this utility model, therefore they will not be elaborated upon.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
