Description

Technical Field

[0001] This invention relates to the field of metallurgical equipment technology, and in particular to a wire feeding guide structure and wire guiding system. Background Technology

[0002] In steel smelting, continuous casting and rolling processes, it is often necessary to continuously add alloy core wires containing specific components to the ladle, molten steel or continuous casting stream through a wire feeder in order to achieve purposes such as deoxidation, alloying and inclusion control.

[0003] With the development of metallurgical technology, there are higher requirements for production efficiency and the precision of alloy element addition, and the existing guide wire structure needs more improvements to meet these requirements.

[0004] However, traditional guide structures are all fixed, resulting in low efficiency in adjustment and replacement, and they are prone to tangling, wire skipping, or jamming, leading to relatively poor guidance. Furthermore, the overall structural design concept is still difficult to meet the requirements of high-precision processes.

[0005] For example, Chinese Patent Application No. 202121055127.5 discloses a wire feeding machine and its wire feeding guide device. The guide device includes a support device, a first guide wheel, and a second guide wheel. A first annular groove is provided on the outer side of the first guide wheel around its rotation center axis; a second annular groove is provided on the outer side of the second guide wheel around its rotation center axis; the two side shaft ends of the first and second guide wheels are respectively detachably installed in the U-shaped groove of the support device, and the first guide wheel is located directly above the second guide wheel. The rotation center axes of the first and second guide wheels are parallel to each other, so that the first and second annular grooves constitute a guide wire passage groove for preventing the wire from jumping.

[0006] The existing technology has the aforementioned drawbacks. Summary of the Invention

[0007] The purpose of this invention is to provide a wire feeding guide structure. This guide structure constructs a continuous, multi-segmented diameter guide section by arranging a movable guide base plate and multiple guide modules on an upright guide support panel. This makes the guiding movement path of multiple alloy core wires controllable, stable and independent, thereby improving the reliability and flexibility of the wire feeding process.

[0008] The present invention also provides a wire feeding system, which adopts the above-mentioned wire feeding guide structure and is used in conjunction with the front wire feeder and the upstream pre-guide plate at the rear and lower end to realize the orderly transition arrangement of multiple alloy core wires in three-dimensional space, so as to meet the requirements of different processes for the wire exit position.

[0009] The above-mentioned objective of the present invention is achieved through the following technical solution: a wire feeding guide structure, comprising an upright guide support panel, wherein a plurality of guide units for guiding alloy core wires are mounted and connected on the guide support panel, and a main inlet hole for the alloy core wires to pass through is provided on the guide support panel. The guide unit comprises a guide base plate, a guide support mounting plate fixed to the guide base plate, and a plurality of spaced guide modules mounted and connected on the guide support mounting plate. The guide base plate has a wire hole for the alloy core wires to pass through, which can cooperate with the main inlet hole. A guide interval for the alloy core wires to pass through is formed on the guide module.

[0010] As a preferred embodiment of the present invention, the guide module includes a bottom mounting plate fixed on the guide support panel, a left guide roller and a right guide roller mounted on the bottom mounting plate at intervals, and a bottom guide roller and a top guide roller at intervals perpendicular to the direction of the bottom mounting plate. The left guide roller, the bottom guide roller, and the top guide roller surround and form the guide interval. The axial directions of the bottom guide roller and the top guide roller are in the left-right direction, and the axial directions of the left guide roller and the right guide roller are perpendicular to the direction of the bottom mounting plate.

[0011] As a preferred embodiment of the present invention, the size of the guide interval of each guide module is smaller the closer it is to the guide substrate.

[0012] As a preferred embodiment of the present invention, the guide support mounting plate is in the shape of a cycloid extending rearward and downward.

[0013] As a preferred embodiment of the present invention, a left I-beam frame and a right I-beam frame are fixed on the bottom mounting plate, and the left and right I-beam frames are spaced apart. The left I-beam frame includes a left bottom beam, a left top beam, and a left middle beam fixed between the left bottom beam and the left top beam, perpendicular to the bottom mounting plate. The right I-beam frame includes a right bottom beam, a right top beam, and a right middle beam fixed between the right bottom beam and the right top beam, perpendicular to the bottom mounting plate. Both the left bottom beam and the right bottom beam are fixed to the bottom mounting plate. A left guide roller is installed and connected to each side of the left middle beam between the left bottom beam and the left top beam. A right guide roller is installed and connected to each side of the right middle beam between the right bottom beam and the right top beam. A bottom guide roller is installed and connected between the left bottom beam and the right bottom beam. A top guide roller is installed and connected between the left top beam and the right top beam.

[0014] As a preferred embodiment of the present invention, the guide substrate is movable along the guide support panel.

[0015] As a preferred embodiment of the present invention, in the initial state, the guide support panel has a row of guide units arranged at intervals from top to bottom on the left and a row of guide units arranged at intervals from top to bottom on the right.

[0016] As a preferred embodiment of the present invention, the guide support panel is provided with a moving groove for the alloy core wire to pass through and move laterally, each guide unit is equipped with one moving groove, and all moving grooves are connected to the main inlet hole and are arranged radially.

[0017] As a preferred embodiment of the present invention, the guide support panel is equipped with a moving device for moving the guide base plate, and the top guide roller is detachably installed between the left top beam and the right top beam.

[0018] A wire feeding system includes the aforementioned wire feeding guide structure, and further includes a wire feeder on the front side of the wire feeding guide structure and a horizontal upstream pre-guide plate below the rear of the wire feeding guide structure. The upstream pre-guide plate has a plurality of upstream pre-guide holes that are spaced apart and allow alloy core wires to pass through vertically. Each guide unit corresponds to one upstream pre-guide hole. In the initial state, the higher the guide unit is, the further back the upstream pre-guide hole is.

[0019] The beneficial effects of the present invention are as follows: by setting a movable guide base plate and a guide support mounting plate on an upright guide support panel, and arranging multiple guide modules along the mounting plate to form a continuous guide path, the alloy core wire is controlled in the front-back, high-low and left-right directions, avoiding large swings and mutual entanglement. Through the guide section formed by the four guide rollers in the guide module, and the design of the guide section size of each guide module gradually decreasing, the alloy core wire gradually converges and stabilizes during the guiding process, reducing the local pressure and wear on a single guide component; With the movable design of the guide base plate on the guide support panel and the matching moving device, the relative position of each guide unit can be easily adjusted. In conjunction with the radial moving grooves on the guide support panel, the guide path of different alloy core wires can be flexibly configured, improving the system adaptability and meeting the needs of high-efficiency and high-precision production. It is possible to replace alloy core wires of different materials, sizes and weights at any time for metallurgy, which is of great help to high-quality metallurgical products. By setting left and right I-beam frames on the bottom mounting plate, a reasonable structural support is formed, making the guide roller mounting structure stable and reliable, easy to maintain and replace, and ensuring the accuracy of the guide interval dimensions. By coordinating the wire feeding guide structure with the front wire feeder and the rear lower upstream pre-guide plate, and the specific correspondence between the upstream pre-guide hole and the guide unit in the front-back and up-down directions, an orderly three-dimensional transition of the alloy core wire from the upper front exit to the lower rear entry hole is achieved, which is suitable for various process layout requirements.

Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings.

[0022] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.

[0023] Examples, such as Figure 1-8 As shown, a wire feeding guide structure includes an upright guide support panel 1. Several guide units for guiding alloy core wires 111 are mounted and connected on the guide support panel 1. The guide support panel 1 has a through-hole 10 for the alloy core wires 111 to pass through. Each guide unit includes a guide base plate 2, a guide support mounting plate 3 fixed to the guide base plate 2, and multiple spaced guide modules mounted and connected to the guide support mounting plate 3. The guide base plate 2 has a through-hole 20 for the alloy core wires 111 to pass through, which mates with the main inlet hole 10. A guide section 40 for the alloy core wires 111 to pass through is formed on the guide module. Specifically: Includes: Guide support panel 1: This is an upright plate fixed to the equipment foundation or frame structure. The thickness and material of the guide support panel 1 can be selected according to the usage environment, generally using a steel plate structure. The alloy core wire 111 needs to pass through the guide support panel 1. The guide support panel 1 needs to be equipped with a main inlet hole 10, which runs through the front and back. Generally, one or two main inlet holes 10 correspond to one wire feeder. Each main inlet hole 10 can only accept one strand of alloy core wire 111. The front end of each strand of alloy core wire 111, i.e., the wire end of the alloy core wire 111, is fed into the drive gear of the wire feeder after passing through the main inlet hole 10. It is then clamped and actively pulled by the gear, achieving precise and stable feeding of the alloy core wire 111. The drive gear usually cooperates with the clamping wheel to clamp the wire end through friction, pulling it out of the wire spool and feeding it into the ladle or molten pool at a set speed and length. If the wire feeder has two drive gears, two main inlet holes 10 are required.

[0024] Guide unit: Installed on the rear side of guide support panel 1, each guide unit corresponds to one alloy core wire 111. The guide unit includes guide base plate 2, guide support mounting plate 3, and multiple guide modules. The guide base plate 2 and guide support panel 1 can be connected in a fixed manner, with the guide base plate 2 and guide support panel 1 as close as possible, and the guide base plate 2 is preferably upright, for example, by directly fixing the two with bolts. It can also be movable, for example, by connecting the guide base plate 2 to the guide support panel 1 through a movable structure, and setting some slide rails for the guide base plate 2 to guide its movement. The guide support panel 1 can be rectangular, and the guide base plate 2 is preferably circular. The guide base plate 2 has wire holes 20, the position of which matches the corresponding main inlet hole 10, and they are through to allow the alloy core wire 111 to pass through. When the corresponding guide unit needs to work, the wire hole 20 of the corresponding guide unit is aligned with the main inlet hole 10.

[0025] Guide support mounting plate 3: One end of it is fixed to the guide base plate 2, which can be fixed by welding or integral molding. The guide structure of this application is preferably made of metal or rigid plastic. For the part of the overall shape that needs to be curved, there is a pre-guide for installation and a bending process to ensure a smoothness, and it extends backward and downward from the guide base plate 2. Multiple guide modules are installed on the guide support mounting plate 3. These guide modules are arranged at intervals along the extension direction of the guide support mounting plate 3, that is, at intervals in the travel direction of the alloy core wire 111, and form multiple guide points, each guide point corresponding to a guide module. Generally, it is advisable to select 2-4 guide modules. The wire hole 20 is located on the front side of the foremost guide module and close to it, that is, at the outlet of the foremost guide module, to facilitate wire exit.

[0026] Through the above structure, the alloy core wire 111 enters multiple guide modules arranged along the guide support mounting plate, passes through each guide interval in sequence, realizes segmented guidance of the overall path of the alloy core wire 111, then passes through the wire hole 20, and then enters the main wire inlet hole 10 from the rear side of the guide support panel, and finally enters the wire feeder drive gear, thus realizing the entire guidance.

[0027] Guide Module: Each guide module includes a bottom mounting plate 4, which is fixed to the guide support mounting plate 3. A left guide roller 41, a right guide roller 42, a bottom guide roller 43, and a top guide roller 44 are mounted on the bottom mounting plate 4. The axial directions of the bottom guide roller 43 and the top guide roller 44 are parallel to the bottom mounting plate 4 in the left-right direction; the axial directions of the left guide roller 41 and the right guide roller 42 are perpendicular to the bottom mounting plate 4. The four guide rollers form a rectangular or near-rectangular guide section 40. The wire hole 20 and the guide base plate 2 are located in front of and close to the foremost guide module. Here, our working direction is described with the front side being the wire feeder and the rear side being the overall direction of the advancing wire. Specifically, the coiled wire spool is placed on the first floor, and the wire feeder is on the second floor. Therefore, the core wire is guided from bottom to top through the entire guide structure, then forward through the main inlet hole 10, and enters the wire feeder. The entire working flow is from back to front, and the description of the structure also refers to this direction. The bottom mounting plate 4 is on the front side of the guide support mounting plate 3, that is, the upper side surface, while each guide roller is mounted on the front side of the bottom mounting plate 4, that is, on its upper side surface.

[0028] The left guide roller 41 and the right guide roller 42 are spaced apart, and the bottom guide roller 43 and the top guide roller 44 are spaced apart in a direction perpendicular to the bottom mounting plate 4. The left guide roller 41, the bottom guide roller 43 and the top guide roller 44 surround and form the guide interval 40.

[0029] In this embodiment, it is preferable that multiple guide modules follow a curved guide path from the rear lower to the front upper along the guide support mounting plate 3. Preferably, the guide support mounting plate 3 is in a cycloid shape extending rear lower, also known as a cycloid or rolling line, which optimizes the climbing speed and direction for the same energy. Of course, the guide support mounting plate 3 can also be a simple arc shape, i.e., an arc-shaped arch extending from the rear lower to the front upper is also feasible.

[0030] To achieve a better guiding and converging effect, the size of the guiding interval 40 of each guiding module is smaller as it gets closer to the guiding substrate 2. The reason why the guiding interval 40 of the guiding module closer to the guiding substrate 2 is smaller, while the guiding interval 40 of the guiding module farther away from the guiding substrate 2 is larger, is to achieve a gradual converging guiding effect, which is a gradual process. The size here includes the interval distance between the left guide roller 41 and the right guide roller 42 and the interval distance between the bottom guide roller 43 and the top guide roller 44, which are preferably reduced synchronously.

[0031] Furthermore, a left I-beam frame and a right I-beam frame are fixed on the bottom mounting plate 4, and the left and right I-beam frames are distributed at intervals. The left I-beam frame includes a left bottom beam 51, a left top beam 52, and a left middle beam 53 perpendicular to the bottom mounting plate 4, which is fixed between the left bottom beam 51 and the left top beam 52. The right I-beam frame includes a right bottom beam 61, a right top beam 62, and a right middle beam 63 perpendicular to the bottom mounting plate 4, which is fixed between the right bottom beam 61 and the right top beam 62. Both the left bottom beam 51 and the right bottom beam 61 are fixed to the bottom mounting plate 4. A left guide roller 41 is installed and connected between the left bottom beam 51 and the left top beam 52 on both sides of the left middle beam 53. A right guide roller 42 is installed and connected between the right bottom beam 61 and the right top beam 62 on both sides of the right middle beam 63. A bottom guide roller 43 is installed and connected between the left bottom beam 51 and the right bottom beam 61. A top guide roller 44 is installed and connected between the left top beam 52 and the right top beam 62.

[0032] The top guide roller (44) is detachably connected between the left top beam (52) and the right top beam (62). It can be installed using existing detachable methods, such as connecting the two ends of the roller shaft of the top guide roller (44) to the left top beam (52) and the right top beam (62) by means of pins, or by spring pressing, using the elastic retaining ring at the shaft end or the interference fit of the shaft diameter to press the roller shaft directly into the hole of the beam, or by thread, that is, the roller shaft end is machined with internal or external threads, and is fixed by tightening bolts or directly screwing into the threaded hole of the mounting beam. These detachable methods are convenient for disassembly and assembly, and also facilitate the threading operation before operation when necessary. Of course, other guide rollers can also be detachably installed and fixed between the corresponding beams.

[0033] The left and right I-beam frames can also be installed and fixed to the bottom mounting plate 4 using existing detachable methods for easy disassembly, assembly, and maintenance. For example, the bottom beam and the bottom mounting plate 4 can be locked together using bolts and nuts. Alternatively, they can be directly welded together.

[0034] Building upon the foregoing, to enhance the structural stability of the guide module, this embodiment employs an I-beam frame support structure. A left and right I-beam frame are fixedly mounted on the bottom mounting plate 4, spaced apart horizontally.

[0035] The left I-beam frame includes a left bottom beam 51, a left top beam 52, and a left middle beam 53. The left bottom beam 51 and the left top beam 52 are fixed to both ends of the left middle beam 53 by welding or integral molding. The left middle beam 53 is perpendicular to the bottom mounting plate 4, so that the left I-beam frame as a whole forms a rigid frame similar to the Chinese character "I". The left I-beam frame is fixed on the bottom mounting plate 4. The right I-beam frame includes a right bottom beam 61, a right top beam 62, and a right middle beam 63. The right bottom beam 61 and the right top beam 62 are fixed to both ends of the right middle beam 63 by welding or integral molding, respectively. The right middle beam 63 is perpendicular to the bottom mounting plate 4, so that the right I-beam frame forms a structure that is symmetrical or similar to the left I-beam frame. The right I-beam frame is fixed on the bottom mounting plate 4. A bottom guide roller 43 is installed between the left bottom beam 51 and the right bottom beam 61, with the axial direction of the bottom guide roller 43 along the left-right direction; a top guide roller 44 is installed between the left top beam 52 and the right top beam 62, also arranged along the left-right direction; a left guide roller 41 is installed between the left bottom beam 51 and the left top beam 52, located on both sides of the left middle beam 53; a right guide roller 42 is installed between the right bottom beam 61 and the right top beam 62, located on both sides of the right middle beam 63. Preferably, there is only one top guide roller 44 and one bottom guide roller 43, and both are located in the middle position in the travel direction of the two left guide rollers 41, that is, in the middle position in the travel direction of the two right guide rollers 42.

[0036] The above structure enables the guide rollers 41, 42, 43, and 44 to form a stable rectangular frame. The guide section 40 is formed by four boundaries, and its size can be achieved by adjusting the spacing between the beams or selecting guide rollers of different specifications to meet the guiding requirements of alloy core wires 111 of different diameters.

[0037] Based on the above, a movable mechanism for the guide substrate 2 on the guide support panel 1 is further designed to adjust the overall position of the guide unit.

[0038] The guide support panel 1 is provided with a slide rail or slide groove along the horizontal direction, and the guide base plate 2 is provided with a corresponding slider or slide groove on the back, so that the guide base plate 2 can slide along the guide support panel 1 in the left-right or front-back direction.

[0039] For ease of operation, a moving device 7, such as a screw-nut mechanism arranged on the side of the guide plate 2, is installed on the guide support panel 1. A drive motor rotates the screw, causing the guide plate 2 to move along the slide rail, changing the position of the wire hole 20 and the guide support mounting plate 3. The moving device 7 can also be a rack and pinion, hydraulic cylinder, or pneumatic cylinder mechanism. For example, a pneumatic cylinder can be directly installed and connected to the guide support panel 1, with the telescopic portion of the cylinder fixing the guide plate 2.

[0040] In the initial arrangement of the guide support panel 1, multiple guide units are arranged at intervals from top to bottom in a row on the left side, and multiple guide units are also arranged from top to bottom in a row on the right side. Using the moving device 7, these guide units can be moved left and right within a certain range, thereby adjusting the position of the alloy core wire 111 corresponding to each unit without changing the overall support structure.

[0041] To facilitate the movement of the guide base plate 2, a movement groove 100 is provided on the guide support panel 1.

[0042] The moving groove 100 is an elongated slot, and each guide unit corresponds to one moving groove 100. The moving groove 100 is connected to the main inlet hole 10 to ensure that the alloy core wire 111 can move laterally within a certain range before entering the wire hole 20 of the guide substrate 2.

[0043] All the moving slots 100 are arranged radially around the main inlet hole 10, that is, with the main inlet hole 10 as the center, several moving slots 100 are distributed in a fan shape in the plane. With this arrangement, the moving slots corresponding to different guiding units on the guide support panel 1 can cover a large lateral range, thereby realizing the diversity of the guiding path of the alloy core wire 111.

[0044] The operation process typically involves the alloy core wire 111 being wound into a spool at a low position in the factory. The wire head is pulled out manually or by a robotic arm and guided to the guide structure. Each wire then passes through several guide sections 40 along the guide path of a guide unit (i.e., the space limited and guided by the guide rollers) and through the wire hole 20. If it is a movable type with multiple guide units, it needs to pass through the moving groove 100. Initially, the wire is not in the position of the main feed hole 10. Only wires requiring feeding slide along the moving groove 100 to the main feed hole 10, moving along with the guide unit. The initial state refers to the state of no feeding and no operation; simply deviating from the main feed hole 10 is sufficient. Of course, the working wire head needs to be further guided to the wire feeder drive gear.

[0045] To achieve better operational processes, further design is required. A lifting beam 9 is installed and connected between the left top beam 52 and the right top beam 62. The lifting beam 9 extends to the left and right and can move in a direction perpendicular to the bottom mounting plate 4. A lifting cylinder 91 is installed and connected between the left top beam 52, the right top beam 62, and the lifting beam 9. The cylinder bodies of the two lifting cylinders 91 can be fixed to the left top beam 52 and the right top beam 62 respectively. The telescopic rods of the two lifting cylinders 91 fix the lifting beam 9. A pressure roller 92 is installed and connected to the lifting beam 9. It can be installed using existing methods, such as using a wheel frame. The function of the pressure roller 92 is to cooperate with the bottom guide roller 43 to press the alloy core wire 111. When the guide unit is not feeding wire, the alloy core wire 111 needs to pause its entry into the wire feeder, but it cannot be fed out, otherwise the wire will retract and need to be re-threaded. Therefore, in the initial state or during switching, the guide unit that is not feeding wire needs to press down on the alloy core wire 111. This is achieved by lifting the lifting beam 9, and the pressure roller 92, in conjunction with the bottom guide roller 43, presses down on the alloy core wire 111. Furthermore, the pressure roller 92 is preferably an active roller, meaning it is equipped with a motor and has its own driving force. It is usually connected to a geared motor or directly driven by the motor through a shaft coupling. The advantage of this is that when wire feeding is needed, the pressure roller 92 presses down on the alloy core wire 111 and feeds it into the drive unit of the wire feeder, eliminating the need for manual or robotic threading, saving costs and improving efficiency. Then, a wire cutter 93 can preferably be installed and connected to the front side of the guide support panel 1. The wire cutter 93 is preferably automatically controlled, such as some automatic wire cutting device or cutting device, and is further preferably movable with a moving device. This allows for better cutting of the alloy core wire 111. That is, when switching between different strands of alloy core wire 111, the alloy core wire 111 in the working state is first pressed by the pressure roller 92, and then cut by the front side of the wire cutter 93. Then the corresponding guide unit moves to the initial position, maintaining the pressed state so that the wire will not loosen. When resuming the working state, simply move the guide unit to the working position, that is, the position of the main wire inlet 10, and then the pressure roller 92 actively rotates to drive the core wire forward and feed it into the drive of the wire feeder. This switching capability allows for the seamless switching between different alloy core wires 111, enabling the orderly addition of metallurgical processes for core wires of different materials. This results in higher precision, greater efficiency, and improved controllability, which is more beneficial for the production of high-quality products. Furthermore, it makes the production process smoother and reduces the likelihood of malfunctions and other problems.

[0046] Furthermore, this embodiment provides a wire feeding system, including the above-mentioned wire feeding guide structure, wire feeder, and preceding guide plate 8.

[0047] The wire feeder is located in front of the wire feeding guide structure. The main wire inlet hole 10 on the guide support panel 1 is aligned with the entry point of the wire feeder, which is also the position of the drive gear. The wire feeder can be a multi-station wire feeder, with each station corresponding to one or more main wire inlet holes 10 on the guide support panel 1. One main wire inlet hole 10 can correspond to multiple guide units, allowing for easy switching between different guide units and their corresponding alloy core wires 111 for wire feeding operations, thus improving efficiency and precision.

[0048] The preceding guide plate 8 is located below and behind the wire feeding guide structure and is horizontal in shape. Several preceding guide holes 80 are formed on the preceding guide plate 8, spaced apart in the front-to-back direction. Each preceding guide hole 80 corresponds to a guide unit. In the initial state, the higher the guide unit, the further back its corresponding preceding guide hole 80 is. That is, the position of the preceding guide hole 80 on the preceding guide plate 8 is misaligned with the vertical arrangement of the guide units on the guide support panel 1, allowing the alloy core wire 111 to be guided upwards from the lower position, first passing through the corresponding preceding guide hole 80, then entering the corresponding upper guide unit. It is initially held in its original state by the aforementioned clamping structure. When operation is required, the corresponding guide unit moves to the main inlet hole 10, and the alloy core wire 111 is actively fed into the wire feeder drive. The core wire is then carried into the wire feeder by the drive gear and fed into subsequent stations, such as immersion nozzles or the inside of the ladle.

[0049] Further optimization involves making the preceding guide hole 80 an elongated hole extending to the left and right or an oblong hole, with the left and right dimensions being 0.5-1 times the length of the moving groove 100 in the left and right directions. This improves the synchronization in the up and down directions during movement and is more helpful in protecting and guiding the core wire.

[0050] In addition, the material of the guide roller can be selected according to the type of alloy core wire 111 and the working environment, such as wear-resistant alloy steel, hard chrome plated steel roller or roller with rubber coating, to reduce damage to the core wire surface.

[0051] When in use, the guide unit does not necessarily need to be used with the main inlet hole 10 to work. If there is a wire feeder at the initial station, the wire can be fed directly. This is suitable for fixed wire feeding operations. If high-quality wire feeding is required, fine wire feeding can be performed by switching between different types of wires as mentioned above.

[0052] The cross-sectional shape of the guide section 40 can be rectangular, rounded rectangle or approximately circular. Different guiding effects can also be achieved by adjusting the diameter and spacing of the guide rollers to adapt to alloy core wires of different diameters or stiffnesses.

[0053] The moving device 7 can be equipped with a position detection device, such as a displacement sensor or encoder, to achieve precise control of the position of the guide plate and can be connected to an automatic control system to achieve automatic adjustment of the guide path.

[0054] The preceding guide hole 80 on the preceding guide plate 8 can adopt a removable bushing structure so that it can be replaced after wear, thus extending the overall service life of the guide plate.

[0055] The guide support panel 1 can be designed as a detachable modular structure, allowing the entire wire feeding guide structure to be flexibly combined according to the layout of different production lines.

[0056] The front-to-back length of the guide support mounting plate 3 of each guide unit should preferably be longer, especially for the uppermost guide support mounting plate 3, in order to further avoid problems such as wire cross-connection.

[0057] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto.
