Description

Technical Field

[0001] This utility model relates to the field of cored wire production technology, specifically to a bismuth manganese iron alloy cored wire feeding device. Background Technology

[0002] Bismuth-manganese ferroalloy cored wire is a composite material used in steelmaking. It consists of an outer sheath and an inner bismuth-manganese ferroalloy conductor. The strength of the bismuth-manganese ferroalloy cored wire depends on the core wire, while its wear resistance and heat resistance depend on the outer sheath. Therefore, cored wire is suitable for high-speed sewing and garments requiring high sewing strength. It is produced by using low-density, easily oxidized refining additives to form the wire, which is then fed into the molten steel using a wire feeder for ladle refining.

[0003] A cored wire feeding device, disclosed in CN222411668U, includes a base plate. A support frame is fixedly mounted on the bottom of the base plate, and a protective cover is fixedly mounted on the top of the base plate. Symmetrically distributed limiting grooves are formed on the rear side of the inner wall of the protective cover, and adjusting screws are rotatably mounted inside both limiting grooves. This is a bismuth-manganese-iron alloy cored wire feeding device.

[0004] This device uses a conveyor wheel and a guide wheel to feed and transmit the cored wire. However, the device uses a linear feeding method, which can cause the cored wire to slip due to low friction between the cored wire and the guide wheel. In addition, linear transmission can easily cause excessive vibration of the cored wire, which can lead to wire breakage. Therefore, it is necessary to design a bismuth-manganese-iron alloy cored wire feeding device to improve the stability of cored wire feeding and transmission. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a bismuth-manganese-iron alloy cored wire feeding device, thereby solving the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a bismuth manganese iron alloy cored wire feeding device, including a workbench, a housing fixedly connected to the upper side of the workbench, a "T"-shaped groove on the housing, the groove including a cavity and an opening, a drive group is provided on both sides of the inner wall of the cavity along the length of the housing, a transmission group is provided between the two drive groups, the transmission group includes two relatively movable connecting plates, a plurality of rotatable rollers are provided on the opposite side of the two connecting plates, a bracket is rotatably connected to the side of the rollers near the connecting plates, a guide post is fixedly connected to each of the four corners of the bracket near the connecting plates, a spring is sleeved on the guide post, the guide post passes through the connecting plate and is slidably connected to the connecting plate, and the two ends of the spring along the axial direction of the guide post are in direct contact with the connecting plate and the bracket respectively.

[0007] The present invention further explains that the drive group includes two pressure rollers, which are rotatably connected to the groove cavity. The roller shafts of the upper set of pressure rollers are rotatably connected to connecting blocks through the groove cavity at both ends along their axial direction. The connecting blocks are slidably connected to the housing.

[0008] The present invention further illustrates that a hydraulic telescopic cylinder is provided on the side of the connecting block away from the workbench. The fixed end of the hydraulic telescopic cylinder is fixedly connected to the housing, and the output end of the hydraulic telescopic cylinder is fixedly connected to the connecting block.

[0009] The present invention further describes that one end of the pressure roller protruding from the housing is fixedly connected to a pulley one through the connecting block. The pulley one is coaxially arranged with the roller shaft. A drive motor is fixedly connected to the housing. A pulley two is fixedly connected to the output end of the drive motor. A tensioning wheel is also provided on the housing. The tensioning wheel is connected to pulley one and pulley two.

[0010] This utility model further illustrates that the groove opening of the first groove faces the side perpendicular to the workbench surface.

[0011] This utility model further illustrates that the two connecting plates are arranged symmetrically above and below each other with the slot as the reference.

[0012] This utility model further illustrates that two hydraulic telescopic cylinders are provided on the side of the connecting plate away from the rotating roller. The two hydraulic telescopic cylinders are respectively provided at both ends of the connecting plate along the length direction. The fixed end of the hydraulic telescopic cylinder is fixedly connected to the inner wall of the groove cavity, and the output end of the hydraulic telescopic cylinder is fixedly connected to the connecting plate.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model, by setting up a drive motor, pulley one, pulley two, and tensioning wheel, drives the pressure rollers of the two drive groups to rotate together through the belt, unifying the transmission speed of the pressure rollers and preventing the problem of cored wire breakage caused by differential speed.

[0014] By setting up rollers, guide posts, and springs, the cored wire is transported. The elastic buffering effect of the springs reduces the vibration generated by the cored wire during transport, thereby preventing the cored wire from breaking.

[0015] The elastic buffering effect of the spring increases the friction of the cored wire during transmission, preventing slippage and thus improving the stability of the cored wire during feeding. Attached Figure Description

[0021] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-3 The present invention provides a technical solution: a bismuth manganese iron alloy cored wire feeding device, including a workbench 1, a housing 2 fixedly connected to the upper side of the workbench 1, a "T" shaped groove 3 is provided on the housing 2, the groove 3 is open at both ends along the length direction, the groove 3 includes a cavity 4 and a slot 5, and the slot 5 of the groove 3 faces the side perpendicular to the workbench 1.

[0023] A drive group 6 is provided on both sides of the inner wall of the cavity 4 along the length of the shell 2, and a transmission group 7 is provided between the two drive groups 6.

[0024] The drive unit 6 includes two pressure rollers 8, which are symmetrically arranged vertically with respect to the groove 5.

[0025] The pressure roller 8 is rotatably connected to the groove cavity 4, wherein the roller shaft of the upper set of pressure rollers 8 passes through the groove cavity 4 at both ends along its axial direction and is rotatably connected to the connecting block 9.

[0026] A hydraulic telescopic cylinder 10 is provided on the side of the connecting block 9 away from the workbench 1. The hydraulic telescopic cylinder 10 is vertically arranged, and its fixed end is fixedly connected to the housing 2. The output end of the hydraulic telescopic cylinder 10 is fixedly connected to the connecting block 9. The housing 2 has a sliding opening 11 corresponding to the roller shaft of the pressure roller 8. Therefore, by driving the output end of the hydraulic telescopic cylinder 10, the pressure roller 8 is controlled to slide up and down along the sliding opening 11, thereby automatically clamping and rotating the cored wire between the pressure rollers 8.

[0027] One end of the pressure roller 8, which protrudes from the housing 2, is fixedly connected to a pulley 12 via a connecting block 9. The pulley 12 is coaxial with the roller. A drive motor 13 is fixedly connected to the housing 2. A pulley 2 14 is fixedly connected to the output end of the drive motor 13. The pulley 2 14 is connected to the two pulleys 12 and forms a triangular belt drive structure. A tensioning wheel 15 is also provided on the housing 2. The tensioning wheel 15 is connected to the pulleys 12 and 14. The tension of the belt is adjusted when the pulleys 12 move by the tensioning wheel 15.

[0028] The transmission assembly 7 includes two connecting plates 16, which are horizontally arranged and symmetrically arranged vertically with the slot 5 as the reference. Several rotating rollers 17 are provided on the opposite side of each of the two connecting plates 16.

[0029] A bracket 18 is rotatably connected to the side of the roller 17 near the connecting plate 16. The bracket 18 has a groove 19. The roller 17 is rotatably connected in the groove 19. The roller 17 is a "V" shaped roller used to transport cored wires of different diameters.

[0030] A guide post 20 is fixedly connected to each of the four corners of the bracket 18 near the connecting plate 16. A spring 21 is sleeved on the guide post 20. The guide post 20 passes through the connecting plate 16 and is slidably connected to the connecting plate 16. The two ends of the spring 21 along the axial direction of the guide post 20 are in direct contact with the connecting plate 16 and the bracket 18, respectively.

[0031] Two hydraulic telescopic cylinders 22 are provided on the side of the connecting plate 16 away from the rotating roller 17. The two hydraulic telescopic cylinders 22 are respectively located at both ends of the connecting plate 16 along the length direction. The fixed end of the hydraulic telescopic cylinder 22 is fixedly connected to the inner wall of the groove cavity 4, and the output end of the hydraulic telescopic cylinder 22 is fixedly connected to the connecting plate 16. The hydraulic telescopic cylinder 22 does not cause obstruction or conflict with the guide column 20. By driving the output end of the hydraulic telescopic cylinder 22 to extend, the upper and lower sets of rotating rollers 17 cooperate with each other to clamp and transmit the cored wire.

[0032] In this embodiment, the operator pulls the cored wire through the slot 5 of the groove 3 into the cavity 4, and controls the output end of the hydraulic telescopic cylinder 22 on the transmission group 7 to extend, so that the upper and lower rollers 17 cooperate to clamp and transmit the cored wire.

[0033] Then, the output ends of the hydraulic telescopic cylinders 10 of the two drive groups 6 are extended, causing the upper pressure roller 8 to descend and cooperate with the lower pressure roller 8 to clamp the cored wire.

[0034] At the same time, the tension of the belt connecting pulley 12 and pulley 14 is adjusted by tensioning wheel 15, and drive motor 13 is started to drive the belt to rotate, thereby driving pressure roller 8 of drive group 6 to rotate and transmit cored wire.

[0035] During transmission, the roller 17 of the transmission group 7 elastically presses the cored wire under the elastic action of the spring 21, and with the cooperation of the drive group 6, it increases the friction of the cored wire during transmission, preventing the cored wire from slipping during transmission.

[0036] Meanwhile, the elastic buffer of spring 21 can effectively reduce the vibration generated by the core wire during transmission, thereby preventing the core wire from breaking.

[0037] The drive motor 13 drives the pressure rollers 8 of the two drive groups 6 to rotate together via a belt, so as to unify the transmission speed of the pressure rollers and prevent the cored wire from breaking due to differential speed.
