Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of winding of magnesium alloy wires, and particularly to a winding device for rare earth magnesium alloy wires. Background Art
[0002] Magnesium alloys have the advantages of low density, high specific strength and high specific stiffness. Adding rare earth elements to magnesium alloys can effectively improve the microstructure and microscopic structure of magnesium alloys, improve the mechanical properties of magnesium alloys at room temperature and high temperature, and enhance the corrosion resistance and heat resistance of magnesium alloys. By using rare earth magnesium alloy wires and relying on arc additive manufacturing technology, large-scale magnesium alloy components can be rapidly formed, and the obtained magnesium alloy components have good application prospects in the fields of aerospace, rail transit, etc.
[0003] The rare earth magnesium alloy wires required for arc additive manufacturing are first obtained by extrusion of bars and then stretching. Due to the close-packed hexagonal crystal structure of magnesium alloys and the addition of rare earth elements, the obtained rare earth magnesium alloy wires have poor plastic deformation ability and are extremely prone to fracture when subjected to large tensile stresses or large curvature bends. Coupled with the limited length of a single rare earth magnesium alloy wire, it is necessary to butt-weld the rare earth magnesium alloy wires to increase the length of the rare earth magnesium alloy wires. During the production of rare earth magnesium alloy wires, finally, the butt-welded rare earth magnesium alloy wires need to be wound into a coil. During the winding process, since the rare earth magnesium alloy wires have poor plasticity at room temperature and there are welding spots in the middle, if the existing winding device is directly used to wind the rare earth magnesium alloy wires, due to the relatively large tension provided by the tension machine in the existing winding device, the rare earth magnesium alloy wires are likely to break during winding. Moreover, when the rare earth magnesium alloy wires break, the existing winding device will still perform the wire winding operation, which will cause the wire feeding end and the wire take-up end in the winding device to both unwind, resulting in the failure of wire winding. If the tension machine is not used during the winding of the rare earth magnesium alloy wires, the frequency of fracture of the rare earth magnesium alloy wires during winding will decrease, but due to the lack of tension provided by the tension machine, the rare earth magnesium alloy wires cannot be closely arranged on the wire coil and become loose, resulting in problems such as interruption of the arc additive process due to poor wire feeding during subsequent use. Therefore, it is impossible to effectively wind the rare earth magnesium alloy wires through the winding device in the prior art. Summary of the Invention
[0004] In order to solve the technical problem that the winding device in the prior art is prone to fracture when winding the rare earth magnesium alloy wires, resulting in the inability to continue the winding of the rare earth magnesium alloy wires, the present invention provides a winding device for rare earth magnesium alloy wires.
[0005] The present invention is implemented by the following technical solutions: A winding device for rare earth magnesium alloy wires, which includes a wire take-up assembly, a wire pay-off assembly, a straightening assembly, a welding assembly, a broken wire detection assembly, a host computer, two wire transmission assemblies, and two clamping assemblies. The two wire transmission assemblies are respectively arranged on both sides of the straightening assembly and are used for bidirectional transmission of the wires. The two clamping assemblies are respectively arranged between the straightening assembly and the wire transmission assemblies on both sides, and the clamping assemblies are used for clamping the wires. The welding assembly is located between the two clamping assemblies and is used for welding the broken wires. The broken wire detection assembly is used for real-time detection of whether the wire between the two wire transmission assemblies is broken. The host computer is electrically connected to the wire take-up assembly, the wire pay-off assembly, the straightening assembly, the wire transmission assembly, the clamping assembly, the welding assembly, and the broken wire detection assembly respectively. The host computer is used to control the operation of the wire take-up assembly, the wire pay-off assembly, and the straightening assembly to wind the wires. And after the broken wire detection assembly detects that the wire is broken, it immediately controls the clamping assembly to clamp both ends of the broken wire. Then it drives the two wire transmission assemblies to rotate synchronously to pull the break point of the wire to the welding assembly, and then controls the welding assembly to weld the break point. After the welding is completed and polished, the winding continues.
[0006] As a further improvement of the present invention, the broken wire detection assembly determines whether the rare earth magnesium alloy wire between the two wire transmission assemblies is broken by detecting the resistance of the wire between the two wire transmission assemblies: If the resistance of the rare earth magnesium alloy wire between the two wire transmission assemblies is greater than the set threshold one, the rare earth magnesium alloy wire between the two wire transmission assemblies is in a broken state.
[0007] As a further improvement of the present invention, the broken wire detection assembly is a resistance detection assembly, which is provided with two contacts. The two contacts are respectively electrically connected to the wire between the two wire transmission assemblies, and the resistance detection assembly is used to measure the resistance of the wire between the two wire transmission assemblies.
[0008] As a further improvement of the present invention, the broken wire detection assembly determines whether the rare earth magnesium alloy wire between the two wire transmission assemblies is broken by detecting the tension of the wire between the two wire transmission assemblies: If the tension of the rare earth magnesium alloy wire between the two wire transmission assemblies is zero, the rare earth magnesium alloy wire between the two wire transmission assemblies is in a broken state.
[0009] As a further improvement of the present invention, the wire transmission assembly uses counter-rotating rollers. The rotation directions of the rollers are opposite, and the wires between the two wire transmission assemblies are tensioned and transported by the rotation of the rollers on the two wire transmission assemblies.
[0010] As a further improvement of the present invention, the clamping assembly includes a sleeve and at least a pair of claw clamps. The sleeve is sleeved outside the claw clamps, and the sleeve adjusts the opening and clamping of the two claw clamps by controlling the distance between the two claw clamps.
[0011] As a further improvement of the present invention, the clamping assembly further includes a cylindrical barrel with a hollow structure. The cross-section of the claw clip is a fan-shaped structure, and the number of claw clips is multiple. The multiple claw clips are circumferentially distributed at one end of the cylindrical barrel, and the multiple claw clips enclose a clamping member with a variable diameter structure. The sleeve is sleeved outside the cylindrical barrel and can move back and forth between the cylindrical barrel and the clamping member to adjust the clamping degree of the clamping member.
[0012] As a further improvement of the present invention, the straightening assembly includes two straighteners arranged perpendicular to each other. A plurality of guide wheels are provided on the straighteners, and the plurality of guide wheels are arranged in a staggered manner up and down on the straighteners.
[0013] As a further improvement of the present invention, the wire take-up assembly includes a wire take-up machine, a wire spool, and a wire arranging device. The wire arranging device is installed on one side of the wire take-up machine close to the wire feeding assembly and is used to sort the wire materials entering the wire spool; the wire spool is installed on the wire take-up machine and is used to wind up the wire materials sorted by the wire arranging device.
[0014] As a further improvement of the present invention, the wire feeding assembly includes a vertical reel with a frustum structure.
[0015] The technical solution provided by the present invention has the following beneficial effects:
[0016] (1) For the winding device of rare earth magnesium alloy wire provided by the present invention, its wire breakage detection component can immediately detect the breakage of the rare earth magnesium alloy wire and immediately control the two clamping components to clamp the broken rare earth magnesium alloy wire through the host computer. At the same time, the wire take-up assembly and the wire feeding assembly will also stop urgently. Through the above series of operations, the problem that the rare earth magnesium alloy wire on the wire take-up assembly and the wire feeding assembly collapses after the breakage of the rare earth magnesium alloy wire can be effectively avoided. Moreover, the winding device of the present invention can also weld the broken rare earth magnesium alloy wire in time through the welding component after the wire breakage, so that the entire winding device can continue to wind up the rare earth magnesium alloy wire, enabling the winding device in this embodiment to smoothly wind up the rare earth magnesium alloy wire with poor plastic deformation ability.
[0017] (2) For the winding device of rare earth magnesium alloy wire provided by the present invention, the tension of the rare earth magnesium alloy wire during the winding process is controlled by adjusting the wire feeding assembly and the straightening assembly. Through the mutual cooperation of the wire feeding assembly and the straightening assembly, while the rare earth magnesium alloy can be tensioned, the problem that the existing tension machine provides too large a tension and causes the rare earth magnesium alloy wire to break can be avoided, thereby realizing stable winding operation of the rare earth magnesium alloy wire.
[0018] (3) The winding device for rare earth magnesium alloy wire provided by the present invention, its straightening component can not only straighten the rare earth magnesium alloy wire to be wound, but also detect the bonding strength of the butt welding points of two rare earth magnesium alloy wires while straightening, so that the rare earth magnesium alloy wire passing through the straightening component can smoothly pass through the wire take-up component for winding.

[0026] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.
[0027] Magnesium alloys are alloys composed of magnesium as the base and other elements added. Their characteristics include low density, high strength, large elastic modulus, good heat dissipation, good shock absorption, greater ability to withstand impact loads than aluminum alloys, and good corrosion resistance to organic substances and alkalis. They are mainly used in industrial sectors such as aviation, aerospace, transportation, chemical engineering, and rockets. In order to further improve the mechanical properties of magnesium alloys at room temperature and high temperature, enhance the corrosion resistance and heat resistance of magnesium alloys, etc., rare earth elements can be added to magnesium alloys to obtain rare earth magnesium alloy wires. Due to the close-packed hexagonal crystal structure of magnesium alloys and the addition of rare earth elements, the plastic deformation ability of the obtained rare earth magnesium alloy wires is poor. And the existing winding devices generally wind wire materials such as steel wires, aluminum wires, and titanium wires. When winding steel wires, aluminum wires, titanium wires, etc., since the strength of these wire materials is relatively high, there is generally no wire breakage when winding these wire materials through the existing winding devices. Due to the poor plastic deformation ability of rare earth magnesium alloy wires, if the existing winding device in the prior art is directly used to wind rare earth magnesium alloy wires, it will cause fractures at the solder joints or the places where rare earth elements segregate in the rare earth magnesium alloy wires. And after the fracture, the existing winding device does not have a wire breakage emergency stop, so that the existing winding device will still perform the wire winding operation, which will cause the wire reels at the wire feeding end and the wire take-up end in the winding device to become loose, resulting in the failure of wire winding. Therefore, it is impossible to stably and effectively wind rare earth magnesium alloy wires through the existing winding device in the prior art.
[0028] On this basis, the applicant has designed a set of winding device suitable for winding rare earth magnesium alloy wires by himself. Its specific structure can be referred to Figures 1 to 3The layer winding device includes a wire taking-up component 1, a wire paying-off component 2, a straightening component 3, two wire feeding components 4, two clamping components 5, a welding component 6, a wire breaking detection component 7 and a host computer 8. The host computer 8 is electrically connected to the wire taking-up component 1, the wire paying-off component 2, the straightening component 3, the wire feeding component 4, the clamping component 5, the welding component 6 and the wire breaking detection component 7 respectively. The host computer 8 is used to control the operation of the wire taking-up component 1, the wire paying-off component 2 and the straightening component 3 to realize the winding of the rare earth magnesium alloy wire. The host computer 8 can also immediately control the clamping component 5 to clamp the two ends of the rare earth magnesium alloy wire after the wire breaking detection component 7 detects that the rare earth magnesium alloy wire is broken, and then drive the two wire feeding components 4 to operate synchronously to pull the breakpoint of the rare earth magnesium alloy wire to the welding component 6, and then control the welding component 6 to weld the breakpoint of the rare earth magnesium alloy wire, and continue to wind after grinding after welding. In this embodiment, due to the poor plastic deformation ability of the rare earth magnesium alloy wire at room temperature, it is very easy to break when subjected to large tensile stress or large curvature bending. Therefore, in this embodiment, the wire break detection component 7 can detect in real time whether the rare earth magnesium alloy wire breaks during the winding process, and transmit the detection result to the host computer 8, and the host computer 8 makes a judgment based on the input result. If a wire break occurs, the host computer 8 will immediately control the clamping component 5 to clamp the two ends of the broken rare earth magnesium alloy wire. By setting the wire break detection component 7 and the clamping component 5, if a wire break occurs when the rare earth magnesium alloy wire is wound, the two ends of the broken wire can be clamped immediately, effectively avoiding the loosening of the rare earth magnesium alloy wire on the winding component 1 and the unwinding component 2. In addition, in this embodiment, a welding component 6 is also set, and the welding component 6 can weld the breakpoint after the rare earth magnesium alloy wire breaks, so that the welded rare earth magnesium alloy wire can continue to be wound. It can be understood that the rare earth magnesium alloy wire layer winding device provided in this embodiment can not only be used to wind rare earth magnesium alloy wires, but can also be used to wind wires of other materials such as aluminum wire, titanium wire, etc.
[0029] Among them, the winding device in this embodiment can wind rare earth magnesium alloy wires with a diameter of 1.2 mm. And during winding, the tension of the rare earth magnesium alloy wires during the winding process can be controlled by adjusting the wire feeding component 4 and the straightening component 3. Through the mutual cooperation of the wire feeding component 4 and the straightening component 3, it is possible to achieve tensioning of the rare earth magnesium alloy without causing the rare earth magnesium alloy wires to break due to excessive tension, thereby realizing stable winding operation of the rare earth magnesium alloy wires. In addition, if the rare earth magnesium alloy wires break during the winding process through the winding device in this embodiment due to excessive bending of the rare earth magnesium alloy wires or insufficient joint strength between two rare earth magnesium alloy wires, the wire breakage detection component 7 in this embodiment can immediately detect the breakage of the rare earth magnesium alloy wires and immediately control the two clamping components 5 to clamp the broken rare earth magnesium alloy wires through the host computer 8. At the same time, the wire take-up component 1 and the wire pay-off component 2 will also stop urgently. Through the above series of operations, it is possible to effectively avoid the problem of the rare earth magnesium alloy wires on the wire take-up component 1 and the wire pay-off component 2 collapsing after the rare earth magnesium alloy wires break. Furthermore, the winding device in this embodiment can also weld the broken rare earth magnesium alloy wires in time through the welding component 6 after the wire breakage, so that the entire winding device can continue to wind the rare earth magnesium alloy wires, enabling the winding device in this embodiment to smoothly wind the rare earth magnesium alloy wires with poor plastic deformation ability.
[0030] Please refer to Figure 1 , the wire pay-off component 2 includes a vertical drum with a frustum structure, and the frustum is a frustum with a smaller upper part and a larger lower part. Setting it as a frustum structure can accommodate wire materials with different coil diameters and improve the practicability of the wire pay-off component 2. In this embodiment, the rotating shaft column at the center of the vertical drum is connected to the base through a damping bearing, so that the vertical drum can remain stable during the wire pay-off process.
[0031] Please refer to Figure 3 and Figure 4, the straightening assembly 3 includes a first bracket 31 and two mutually perpendicular straighteners 32, and the two mutually perpendicular straighteners 32 are installed on the first bracket 31. A plurality of guide wheels 33 are provided on the straightener 32, and the plurality of guide wheels 33 are arranged in a vertically staggered manner on the straightener 32. During the actual setting process, the guide wheels 33 can be divided into upper guide wheels 33 and lower guide wheels 33. Among them, the surfaces of the upper guide wheels and the lower guide wheels both have U-shaped grooves (not shown in the figure). The axle of the lower guide wheel 33 is fixed, and the axle of the upper guide wheel 33 can be pressed down by a spring device to adjust the distance between the upper guide wheel and the lower guide wheel so that the straightener can straighten rare earth magnesium alloy wires with different diameters. During the actual straightening process, one set of straighteners can squeeze the rare earth magnesium alloy wire in the vertical direction, and the other set of straighteners can squeeze the rare earth magnesium alloy wire in the horizontal direction. By setting two sets of straighteners, the rare earth magnesium alloy wire passing through the straightening assembly 3 can be effectively straightened, and tension can also be provided for the rare earth magnesium alloy wire passing between the upper guide wheel 33 and the lower guide wheel 33. In addition, the straightening assembly of this embodiment can also detect the tensile and bending strengths of the butt welds of two rare earth magnesium alloy wires. If a wire break occurs, the winding can be immediately stopped, and the break point can be pulled to the welding assembly 6 for re-welding. If no wire break occurs, it means that the tensile and bending strengths of the butt welds between the two rare earth magnesium alloy wires meet the requirements, so that the wound rare earth magnesium alloy wire will not break easily during use. The straightening assembly 3 can not only straighten the rare earth magnesium alloy wire to be wound, but also detect the bonding strength of the butt welds of the two rare earth magnesium alloy wires during straightening. If the bonding strength of the butt welds of the two rare earth magnesium alloy wires is insufficient, it is easy to break when passing through the straightening assembly 3. If the bonding strength of the butt welds of the two rare earth magnesium alloy wires is strong enough, it can pass through the straightening assembly 3 smoothly. Through the above operations, the straightening assembly 3 can detect the bonding strength of the butt welds of the two rare earth magnesium alloy wires.
[0032] The guide wheel 33 can be a roller made of ceramic material, which can ensure that the surface of the rare earth magnesium alloy wire will not be scratched during straightening, and can also insulate the rare earth magnesium alloy wire passing through the straightening assembly 3 from the metal part on the straightener 32, achieving the purpose of protecting the rare earth magnesium alloy wire during the straightening and winding process.
[0033] The number of wire feeding assemblies 4 can be two, which are used for bidirectional feeding of rare earth magnesium alloy wire. One wire feeding assembly 4 can be arranged between the wire paying-off assembly 2 and the straightening assembly 3, and is used for feeding the rare earth magnesium alloy wire to be wound on the wire paying-off assembly 2 into the straightening assembly 3. The other wire feeding assembly 4 can be arranged between the wire winding assembly 1 and the straightening assembly 3, and this wire feeding assembly 4 is used for feeding the rare earth magnesium alloy wire straightened by the straightening assembly 3 into the wire winding assembly 1, so that the wire winding assembly 1 can wind the straightened rare earth magnesium alloy wire. The wire feeding assembly 4 includes a second bracket 41 and at least one set of opposing rollers 42. One set of opposing rollers 42 is arranged in sequence along the vertical direction of the second bracket 41, and the rotation directions of one set of opposing rollers 42 are opposite to each other. Through the opposing rollers 42 on the two wire feeding assemblies 4, tensioning and feeding of the rare earth magnesium alloy wire can be achieved. It can be understood that in this embodiment, if only the feeding operation of the rare earth magnesium alloy wire is required, the opposing rollers 42 on the two wire feeding assemblies 4 can be controlled to maintain the same rotation speed. If the rare earth magnesium alloy wire needs to be tensioned, the rotation speeds of the opposing rollers 42 on the two wire feeding assemblies 4 can be adjusted so that the rotation speeds of the opposing rollers 42 on the two wire feeding assemblies 4 are different, and the purpose of tensioning the rare earth magnesium alloy between the two wire feeding assemblies 4 can be achieved.
[0034] The straight line where the gap between the upper and lower guiding wheels 33 on the straightener 32 is located coincides with the straight line where the gap between the opposing rollers 42 on the wire feeding assembly 4 is located. The purpose of this design is to keep the rare earth magnesium alloy wire between the two wire feeding assemblies 4 in a horizontal state all the time, avoid large-curvature bending during winding, and thus reduce the risk of wire breakage during winding.
[0035] Please refer to Figure 3 , the wire breakage detection component 7, which is used for real-time detection of whether the wire between the two wire feeding assemblies 4 is broken, and transmits the detected data to the host computer 8. The host computer 8 judges by the data transmitted by the wire breakage detection component 7 received. When a wire breakage occurs, the host computer 8 will immediately control the clamping component 5, and the clamping component 5 will immediately clamp the two ends of the broken wire of the rare earth magnesium alloy wire to prevent the rare earth magnesium alloy wire from sliding continuously, thereby preventing the wire winding assembly 1 and the wire paying-off assembly 2 from collapsing.
[0036] In this embodiment, the broken wire detection component 7 can determine whether the rare earth magnesium alloy wire between the two wire feeding components 4 is broken in the following ways: (1) The broken wire detection component 7 can determine whether the rare earth magnesium alloy wire between the two wire feeding components 4 is broken by detecting the resistance of the rare earth magnesium alloy wire between the two wire feeding components 4. The specific determination process is as follows: If the broken wire detection component 7 detects that the resistance of the rare earth magnesium alloy wire between the two wire feeding components 4 is greater than the set threshold one, it indicates that the rare earth magnesium alloy wire between the two wire feeding components 4 is in a broken state. (2) The broken wire detection component 7 can also determine whether the rare earth magnesium alloy wire between the two wire feeding components 4 is broken by detecting the tension of the rare earth magnesium alloy wire between the two wire feeding components 4. The specific determination process is as follows: If the broken wire detection component 7 detects that the tension of the rare earth magnesium alloy wire between the two wire feeding components 4 suddenly becomes zero, it indicates that the rare earth magnesium alloy wire between the two wire feeding components 4 is broken.
[0037] Among them, when the broken wire detection component 7 selects the first method for broken wire detection, the broken wire detection component 7 can be a resistance detection component. The resistance detection component is provided with two contacts. One contact is electrically connected to the rare earth magnesium alloy wire at one of the wire feeding components 4, and the other contact is electrically connected to the rare earth magnesium alloy wire at the other wire feeding component 4. Through the two contacts, a closed electrical circuit is formed between the resistance detection component and the rare earth magnesium alloy wire between the two wire feeding components 4. During the actual detection process, when the rare earth magnesium alloy wire between the two wire feeding components 4 is broken, the resistance on the resistance detection component will tend to be infinite at this time, and the detected resistance value will exceed the threshold one set by the host computer 8. Through this determination, the host computer 8 can obtain the information that the rare earth magnesium alloy wire between the two wire feeding components 4 is broken, so that the host computer 8 can immediately control the clamping component 5 to clamp the broken rare earth magnesium alloy wire.
[0038] When the broken wire detection component 7 selects the second method for broken wire detection, the broken wire detection component 7 can be a tension sensor. The tension sensor can be used to detect the tension of the rare earth magnesium alloy wire between the two wire feeding components 4. Since the two wire feeding components 4 and the straightening component 3 provide tension to the rare earth magnesium alloy wire between the two wire feeding components 4, during the actual winding process, the rare earth magnesium alloy wire between the two wire feeding components 4 always has tension. Only when the rare earth magnesium alloy wire is broken, the tension detected by the tension sensor may be zero. Therefore, if the tension detected by the tension sensor is zero, it indicates that the rare earth magnesium alloy wire between the two wire feeding components 4 is in a broken state at this time. The host computer 8 makes a judgment by obtaining the tension data of the tension sensor in real time. If the tension is zero, the host computer 8 immediately controls the clamping component 5 to clamp the broken rare earth magnesium alloy wire.
[0039] There are two clamping assemblies 5, which are respectively arranged between the straightening assembly 3 and the wire conveying assemblies 4 on both sides. The clamping assemblies 5 are used to clamp the rare earth magnesium alloy wire. In the actual winding process, if the wire break detection assembly 7 finds that the rare earth magnesium alloy wire is broken, it can immediately transmit the information to the host computer 8, and the host computer 8 can also immediately control the clamping assembly 5 to clamp the broken rare earth magnesium alloy wire to prevent the wire from continuing to slide, thereby preventing the rare earth magnesium alloy wire on the winding assembly 1 and the unwinding assembly 2 from becoming loose.
[0040] In this embodiment, the clamping assembly 5 can clamp the broken rare earth magnesium alloy wire by means of a claw clamp 54. A specific structure of the clamping assembly 5 is listed below. Figure 5 and Figure 6 The clamping assembly 5 may include a mounting seat 51, a sleeve 52, a cylindrical tube 53 with a hollow structure, a driving member, and a plurality of claw clamps 54. The sleeve 52 is sleeved on the outside of the claw clamp 54, and the sleeve 52 adjusts the opening and clamping of the two claw clamps 54 by controlling the distance between the two claw clamps 54. The cross section of the claw clamp 54 is a fan-shaped structure, and the claw clamp 54 has a certain elasticity. The plurality of claw clamps 54 are circumferentially distributed on one side of the cylindrical tube 53, and the plurality of claw clamps 54 are able to surround a clamping member of a variable diameter structure, and the diameter of the clamping member gradually expands from one end of the cylindrical tube 53 to the outside. The sleeve 52 is sleeved on the outside of the cylindrical tube 53, and the driving member is connected to the sleeve 52, and the driving member is electrically connected to the host computer 8. After the host computer 8 issues a clamping command, the driving member will drive the sleeve 52 to move to the clamping member, so that the plurality of claw clamps 54 are retracted, thereby realizing the clamping operation. When the upper computer 8 issues a release command, the driving member will drive the sleeve 52 away from the clamping member, and the multiple claw clamps 54 can be restored to their original state, that is, the release operation is achieved. The driving member can be a cylinder. The other end of the cylindrical tube 53 can be threadedly fixed on the mounting seat 51, and the clamping assembly 5 can be fixed on the bracket 2 41 of the line transmission assembly 4 through the mounting seat 51. The clamping range of the clamping member surrounded by the multiple claw clamps 54 is 1.0mm-1.6mm. It can be understood that when the clamping member is clamped, its aperture range is 1.0mm-1.2mm; when the clamping member is loosened, its aperture range is 1.4mm-1.6mm.
[0041] The welding assembly 6 is located between the two clamping assemblies 5 and is used to weld the rare earth magnesium alloy wire after being broken. In this embodiment, the welding assembly 6 is arranged on the side of the straightening assembly 3 close to the pay-off assembly 2. The purpose of arranging the welding assembly 6 on the side close to the pay-off assembly 2 is that the rare earth magnesium alloy wire after being welded by the welding assembly 6 can enter the straightening assembly 3 for straightening, thereby improving the stability of the subsequent take-up assembly 1 for winding the welded rare earth magnesium alloy.
[0042] In this embodiment, when the rare earth magnesium alloy wire breaks and is clamped by the clamping assembly 5, the break point of the rare earth magnesium alloy wire can be pulled to the welding assembly 6 by the following method. The first method: manually pull the rare earth magnesium alloy wire. After the clamping assembly 5 clamps the broken rare earth magnesium alloy wire, the break point of the rare earth magnesium alloy wire can be manually pulled to the welding assembly 6, and the two ends of the broken rare earth magnesium alloy wire are aligned at the welding assembly 6. After alignment, the welding assembly 6 is used to perform welding treatment on the aligned rare earth magnesium alloy wire. After welding is completed and polished, the layer winding device is started, and the layer winding device can continue to straighten and wind the welded rare earth magnesium alloy wire. The second method: use an automated device to pull the rare earth magnesium alloy wire. When an automated device is selected for pulling, a robotic arm in the prior art can be selected. After the clamping assembly 5 clamps the broken rare earth magnesium alloy wire, the upper computer 8 can be used to control the two robotic arms to clamp the two ends of the broken rare earth magnesium alloy wire respectively, then control the two clamping assemblies 5 to loosen, and simultaneously control the wire take-up assembly 1 and the wire pay-off assembly 2 to reverse. Finally, the upper computer 8 is used to control the two robotic arms to pull the broken rare earth magnesium alloy wire to the welding assembly 6 respectively. Among them, in this step, the purpose of loosening the clamping assembly 5 and reversing the wire take-up assembly 1 and the wire pay-off assembly 2 is to cooperate with the robotic arm so that the robotic arm can pull the broken rare earth magnesium alloy wire to the welding assembly 6. When the robotic arm pulls the broken rare earth magnesium alloy wire to the welding assembly 6, the two ends of the broken rare earth magnesium alloy wire are aligned, and after alignment, the welding assembly 6 is used to perform welding treatment on the aligned rare earth magnesium alloy wire.
[0043] In the above process, whether manual welding or an automated device is used to weld the broken rare earth magnesium alloy wire, if the break position is at one end of the straightening assembly 3 close to the wire take-up assembly 1, the rare earth magnesium alloy wire at the end connected to the wire take-up assembly 1 needs to move back, pass through the straightening assembly 3, then enter the welding assembly 6, and be aligned with the rare earth magnesium alloy wire at the other end at the welding assembly 6 and then welded.
[0044] Please refer to Figure 1 and Figure 3, the wire take-up assembly 1 includes a wire take-up machine 11, a wire spool 12, a wire arranging device 13, and an emergency stop switch 14. The wire take-up machine 11 is arranged on the side of the straightening assembly 3 away from the wire pay-off assembly 2, and the wire take-up machine 11 is located outside the wire transmission assembly 4. The wire spool 12 is fixed on the rotating shaft of the wire take-up machine 11, and the rotation speed and direction of the rotating shaft are controlled by the motor inside the wire take-up machine 11. The wire take-up machine 11 can adjust the rotation speed and direction of its internal motor with the help of a frequency converter, so as to adjust the working speed and force of the wire take-up assembly 1 according to the actual winding requirements. The wire spool 12 is used to wind the straightened rare earth magnesium alloy wire. The wire spool 12 is generally a common I-shaped wire spool. The wire arranging device 13 is installed on the side of the wire take-up machine 11 close to the wire transmission assembly 4. The wire arranging device 13 is linked with the motor, so that the wire arranging device 13 can achieve precise lateral movement according to the rotation speed of the motor and the diameter of the wire to be wound, and realize the close arrangement of the straightened wire. One end of the emergency stop switch 14 is electrically connected to the motor, and the other end is electrically connected to the host computer 8. The emergency stop switch 14 can control the emergency stop of the motor in the wire take-up machine 11 under the control of the host computer 8 when the wire breakage detection component 7 detects that the rare earth magnesium alloy wire breaks, so as to avoid the phenomenon that the wire wound on the wire spool 12 becomes loose after the wire breakage.
[0045] In this embodiment, the welding assembly 6 can be welded by the method of resistance butt welding, and it can be a common resistance butt welding device in the prior art.
[0046] The host computer 8 is a computer that can directly issue control instructions. By electrically connecting the host computer 8 to the wire pay-off assembly 2, the straightening assembly 3, the wire take-up assembly 1, the wire transmission assembly 4, the clamping assembly 5, the welding assembly 6, and the wire breakage detection component 7 respectively, it is possible to realize the unified control of the operation between these components through the host computer 8, and realize the automatic winding operation of the rare earth magnesium alloy wire. The following lists a specific working procedure during the winding of the rare earth magnesium alloy wire:
[0047] (1) First, start the wire pay-off assembly 2, the straightening assembly 3, and the wire take-up assembly 1. The rare earth magnesium alloy wire to be wound on the wire pay-off assembly 2 passes through the wire transmission assembly 4 and the clamping assembly 5 close to the wire pay-off assembly 2 in sequence and enters the straightening assembly 3. After the straightening assembly 3 straightens the rare earth magnesium alloy wire, it passes through the clamping assembly 5 and the wire transmission assembly 4 close to the wire take-up assembly 1 in sequence, and finally enters the wire take-up assembly 1 for winding operation.
[0048] (2) During the winding process, the wire breakage detection component 7 will detect in real time whether the rare earth magnesium alloy wire between the two wire feeding components 4 is broken. When the wire breakage detection component 7 detects that the rare earth magnesium alloy wire between the two wire feeding components 4 is broken, the host computer 8 will immediately control the two clamping components 5 to clamp the rare earth magnesium alloy wire between the two wire feeding components 4. At the same time, the host computer 8 will control the wire winding component 1, the wire feeding component 2, and the straightening component 3 to stop running.
[0049] (3) After clamping is completed, the two ends of the broken rare earth magnesium alloy wire can be manually grasped respectively; then the host computer 8 controls the two clamping components 5 to loosen, and controls the wire winding component 1 and the wire feeding component 2 to reverse. The operator can pull the broken rare earth magnesium alloy wire to the welding component 6, align it at the welding component 6, and then control the welding component 6 by the host computer 8. The welding component 6 can perform welding operations on the broken rare earth magnesium alloy wire.
[0050] (4) After welding and grinding are completed, the host computer 8 controls the welding component 6 to stop running. The host computer 8 then controls the wire feeding component 2, the wire feeding component 4, the straightening component 3, and the wire winding component 1 to run, and continues to wind the rare earth magnesium alloy wire through the operation of the above components.
[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
