Description

Technical Field

[0001] The utility model relates to the technical field of cored wire feeding, in particular to a cored wire feeding device. Background Art

[0002] Core-spun wire is also called powder core wire. It mainly focuses on three aspects: inoculation, refining outside the furnace, and alloying of special elements. The performance test of the fixture is to test the overall performance and function of the welding fixture. The core-spun wire is a sewing thread made of filament as the core and covered with natural fiber. The strength of the core-spun wire depends on the core wire, while the wear resistance and heat resistance depend on the outer yarn. Therefore, the core-spun wire is suitable for high-speed sewing and clothing that requires high sewing firmness. The refining additives with low density and easy oxidation are made into wire, and the wire is put into the deep of the molten steel by a wire feeder to refine the molten steel outside the furnace.

[0003] The Chinese patent publication number is CN218291002U. The patent discloses a wire feeding device for an oxidation-resistant alloy cored wire, which includes a wire feeding body, a wire feeding tube is fixedly connected to the left outer surface of the wire feeding body, and a protective tube is movably connected to the outer circumferential surface of the wire feeding tube. The invention solves the problem that when the existing wire feeding device pulls the cored wire, the cored wire pulled out in circles like a spring will swing rapidly left and right. If it is accidentally whipped onto a worker, it will seriously threaten the worker's personal safety.

[0004] With respect to the above-mentioned related technologies, the device has some shortcomings.

[0027] See also Figure 1-4 , an embodiment provided by the utility model:

[0028] A cored wire feeding device, comprising:

[0029] Base plate 1, a support frame 2 is fixedly installed at the bottom of the base plate 1, a protective cover 6 is fixedly installed at the top of the base plate 1, and a symmetrically distributed limiting groove 24 is opened on the rear side of the inner wall of the protective cover 6.

[0031] A guide rail 5 is fixedly installed on one side of the base plate 1, and a threaded rod 17 is rotatably installed inside the guide rail 5. A second motor 15 is fixedly installed on the bottom of the guide rail 5, and the driving end of the second motor 15 passes through the bottom of the guide rail 5 and extends to the inside of the guide rail 5 and is fixedly connected to the bottom end of the threaded rod 17. An adjusting block 16 is sleeved on the outer wall of the threaded rod 17, and the adjusting block 16 is slidably connected to the inner wall of the guide rail 5. A connecting block 3 is fixedly installed on one side of the adjusting block 16, and a guide tube 4 is fixedly installed on one side of the connecting block 3, which has a guiding effect on the cored wire, effectively preventing the cored wire from being difficult to feed into the ladle due to deformation, twisting, etc., and ensuring that the cored wire is smoothly fed into the ladle.

[0032] In one embodiment, a threaded hole matched with the threaded rod 17 is opened on the top of the adjusting block 16, and the adjusting block 16 is threadedly connected to the threaded rod 17 through the threaded hole opened on the top.

[0033] In one of the preferred embodiments, the driving mechanism includes a fixed plate 9, and the number of the fixed plates 9 is two, the two fixed plates 9 are symmetrically distributed and fixedly installed on the top of the protective cover 6, a worm 10 is rotatably installed between the two fixed plates 9, a third motor 21 is fixedly installed on one side of one fixed plate 9, and the driving end of the third motor 21 passes through one side of a fixed plate 9 and extends to between the two fixed plates 9 and is fixedly connected to one end of the worm 10, a worm wheel 11 is fixedly installed on the top outer wall of the two adjusting screws 12, and the worm wheel 11 is meshed with the worm 10, thereby realizing the synchronous vertical movement of the two structures of the tensioning wheel 23 and the guide wheel 7 driven by a driving source, which is convenient for the synchronous limiting of the cored wire, and can also reduce the operating cost of the equipment and improve the economy of the equipment.

[0034] In one embodiment, a threaded hole matched with the adjusting screw rod 12 is opened on the top of the movable block 22, and the movable block 22 is threadedly connected to the adjusting screw rod 12 through the threaded hole opened on the top of the movable block 22.

[0035] In one preferred embodiment, the movable frame 20 corresponds to the position of the tensioning wheel 23, and the fixed frame 8 corresponds to the position of the conveying wheel 13, which can ensure that the two sets of guide wheels 7 and the tensioning wheel 23 and the conveying wheel 13 can effectively limit the cored wire.

[0036] The working principle of the utility model is as follows: the electrical components appearing in the present application are all externally connected to a power source and a control switch when in use. When in use, the cored wire is passed through the tensioning wheel 23 and between the conveying wheel 13 and the two sets of guide wheels 7. At the same time, the third motor 21 is controlled by the switch to start working. The driving end of the third motor 21 drives the worm 10 to rotate. Through the meshing of the worm 10 and the worm wheel 11, the two adjusting screws 12 are rotated synchronously. Through the threaded transmission of the adjusting screw 12 and the movable block 22, and the sliding relationship between the movable block 22 and the limiting groove 24, the two movable blocks 22 are synchronously moved vertically, so that the upper tensioning wheel 23 and the guide wheel 7 are moved vertically. When the tensioning wheel 23 and the upper guide wheel 7 move downward and contact the outer wall of the cored wire, the guide wheel 7 will generate an extrusion force on the cored wire, and the downward pressure of the upper guide wheel 7 is detected by the pressure sensor 19, and the guide wheel 7 is controlled by the lifting structure. The downward pressure of the wheel 7 prevents the cored wire from being damaged due to excessive downward pressure, ensures that the conveying wheel 13 and the tensioning wheel 23 and the two groups of guide wheels 7 have moderate limiting tension on the cored wire, and immediately controls the first motor 14 to start working through the switch after completing the limiting fixation of the cored wire, and the driving end of the first motor 14 drives the conveying wheel 13 to rotate, and the cored wire is conveyed through the cooperation of the conveying wheel 13 and the tensioning wheel 23. Through the setting of the pressure sensor 19, the pressure control of the cored wire by the device can be realized, and the occurrence of excessive or insufficient pressure is avoided, the practicality of the device is improved, and it is conducive to the stable transportation of the cored wire. In addition, under the common limiting of the two groups of guide wheels 7, the conveying wheel 13 and the tensioning wheel 23, the straightening effect of the cored wire can be achieved, which further improves the stability of the cored wire during the transportation process, and the drive of the guide wheel 7 and the tensioning wheel 23 share a driving source, which reduces the operating cost of the equipment and improves the economy of the equipment.

[0037] In the process of feeding the cored wire, the second motor 15 is controlled by the switch to start working, and the driving end of the second motor 15 drives the threaded rod 17 to rotate. Through the threaded transmission of the threaded rod 17 and the adjusting block 16, and the sliding relationship between the adjusting block 16 and the guide rail 5, the adjusting block 16 drives the guide tube 4 to move vertically stably through the connecting block 3, and the height of the guide tube 4 is adjusted. Then, during the transportation process, the cored wire passes through the inside of the guide tube 4 and is output from the bottom end of the guide tube 4, which effectively prevents the cored wire from being difficult to feed into the ladle due to deformation, twisting, etc., and ensures that the cored wire is smoothly fed into the ladle.
