Description

Technical Field

[0001] The invention relates to the technical field of enameled round wire testing, and in particular to an enameled round wire automatic flattening testing device. Background Art

[0002] Large-sized enameled round wires are usually used in high-power motors, transformers and other applications that require higher current carrying capacity and mechanical strength. In order to obtain a larger cross-sectional area of ​​the wire in a specific space to reduce resistance and improve heat dissipation performance, an enameled round wire flattening process is added. For details, please refer to the relevant content in publication number CN116487180A.

[0003] The essence of the flattening process is to use a roller structure to roll the round wire. The rolling process is relatively simple. Excessive flattening will cause the performance of this part of the enameled wire to drop significantly. Insufficient flattening may require rewinding and trimming, which wastes work time. In addition, the conventional flattening amount detection process is later than the flattening process, which is a belated detection process. If the flattening amount at a single point position has deviated during the continuous flattening process, it will directly affect the production efficiency of the entire line, or directly affect the performance of the enameled flat wire. This application proposes a solution to this problem. Summary of the invention

[0004] The purpose of the present invention is to provide an automated flattening test device for enameled round wire. Regarding the flattening process of enameled round wire, the rolling action of the conventional flattening process is relatively simple, which may cause deviation in the flattening amount. Moreover, because the flattening process is a continuous process, the conventional flattening amount detection process lags behind the flattening process, which is a late detection process and it is difficult to grasp the flattening effect in the actual flattening process.

[0005] The object of the present invention can be achieved by the following technical scheme: an automated flattening test device for enameled round wire, comprising a whole wire assembly, a rolling assembly, a traction assembly and a multi-state action cross-linking system arranged in sequence, wherein a secondary wire roller and a main wire roller are respectively arranged in the middle position of the rolling assembly from top to bottom, and a front lower pressure roller and a rear lower pressure roller are respectively arranged at the two sides of the rolling assembly corresponding to the main wire roller;

[0006] The enameled round wire is sequentially subjected to the wire straightening action of the wire straightening assembly and the rolling action of the rolling assembly to obtain the enameled flat wire. The enameled flat wire is wound up by the traction assembly. During the rolling action, the front lower pressure roller and the rear lower pressure roller are used to perform a wire jumper adjustment action. A multi-state action self-checking model associating the rolling action, the wire jumper adjustment action and the winding action is established in the multi-state action cross-linking system.

[0007] It is further configured as follows: a front conductor assembly is arranged between the line straightening assembly and the front lower pressure roller, and a rear conductor assembly is arranged between the rear lower pressure roller and the traction assembly.

[0008] It is further configured as follows: the roller pressing assembly is provided with front and rear position jumper wire assemblies corresponding to the front lower pressing roller and the rear lower pressing roller, and a middle jumper wire assembly corresponding to the main line roller.

[0009] It is further configured as follows: the front and rear jumper assemblies and the middle jumper assembly both include a coupling seat, the front and rear jumper assemblies are also provided with a self-inspection working assembly, the middle jumper assembly is also provided with an active push cylinder, and the front lower pressure roller and the rear lower pressure roller are provided with a height difference in the vertical direction.

[0010] It is further configured as follows: the coupling seat is arranged at the two end positions of the front lower pressure roller, the rear lower pressure roller and the main line roller in a rotating connection manner, and the coupling seat is slidably connected along the vertical direction in the rolling assembly, and a driving motor corresponding to the secondary line roller is installed in the rolling assembly.

[0011] It is further configured as follows: the output shafts of the main action push cylinder and the self-checking working component are fixedly connected to the coupling seat in the main line roller, and the self-checking working component includes a secondary action push cylinder and a tension sensing structure.

[0012] It is further configured as follows: in the polymorphic action self-detection model, the tension data in the tension sensing structure is used as a variable, and the traction data in the traction assembly is used as a quantitative quantity to perform a polymorphic action detection process, the actual flattening state in the rolling action is obtained by the polymorphic action detection process, and a cross-linking control command is sent to the middle jumper assembly and the front and rear jumper assemblies according to the actual flattening state.

[0013] The present invention has the following beneficial effects:

[0014] 1. The essence of the flattening process of enameled round wire is to use the main wire roller and the auxiliary wire roller to complete the rolling action, and flatten the enameled round wire into the enameled flat wire. In order to ensure the flattening amount, the rolling action is locally optimized and improved, and the conventional after-the-fact detection method is abandoned. Specifically, the front lower pressure roller and the rear lower pressure roller are respectively added to the two sides of the main wire roller and the auxiliary wire roller. The front lower pressure roller and the rear lower pressure roller will not directly interfere with the rolling action in the middle position. They are mainly used as the conduction structure of the enameled round wire or the enameled flat wire. The overall process does not use the main wire roller as a real-time monitoring structure. On the contrary, the actual state of flattening in the rolling action is indirectly fed back through the change in the tension data of the front lower pressure roller and the rear lower pressure roller relative to the enameled round wire or the enameled flat wire;

[0015] 2. Based on the above content, the key content of the present invention is that when there is a deviation in the flattening amount of the enameled round wire, it directly affects the conduction speed of the enameled round wire at the main wire roller and the auxiliary wire roller, and when the conduction speed of the enameled round wire at the main wire roller and the auxiliary wire roller is significantly different, it will directly cause the tension at the front lower pressure roller and the rear lower pressure roller to change, and specifically according to the numerical comparison of the tension data at the front lower pressure roller and the rear lower pressure roller, it can directly and in real time feedback whether there is a flattening amount deviation when the enameled round wire is flattened, so as to avoid affecting the production efficiency of the whole line;

[0016] 3. Optimization of the flattening die in the flattening process: essentially, the flattening thickness is changed by the movement of the main line roller relative to the auxiliary line roller, and the pressing groove on the main line roller serves as the molding structure for flattening the enameled round wire into the enameled flat wire. In this way, the width after flattening is directly limited. The key is to focus on the adjustment method of the flattening thickness. To be more specific, the flattening speed of the enameled round wire at the pressing groove is mainly optimized to adjust and feedback the flattening thickness. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] Embodiment 1: For the flattening process of enameled round wire, the rolling action of the conventional flattening process is relatively simple, which may cause deviation in the flattening amount. In addition, because the flattening process is a continuous process, the conventional flattening amount detection process is after the flattening process, which is a late detection process and it is difficult to grasp the flattening effect in the actual flattening process. The following technical solution is proposed:

[0027] Reference Figures 1 to 5 In this embodiment, an automated flattening test device for enameled round wire is provided, comprising a whole wire assembly 1, a rolling assembly 3, a traction assembly 5 and a multi-state action cross-linking system arranged in sequence, wherein a secondary wire roller 8 and a main wire roller 10 are arranged in the middle position of the rolling assembly 3 from top to bottom, and a front lower pressure roller 601 and a rear lower pressure roller 602 are arranged at the two sides of the rolling assembly 3 corresponding to the main wire roller 10;

[0028] The enameled round wire is sequentially passed through the wire straightening action of the wire straightening component 1 and the rolling action of the rolling component 3 to obtain the enameled flat wire, the enameled flat wire is wound through the traction component 5, and the wire jumper adjustment action is performed through the front lower pressure roller 601 and the rear lower pressure roller 602 during the rolling action, and a multi-state action self-inspection model associating the rolling action, the wire jumper adjustment action and the winding action is established in the multi-state action cross-linking system, a front conductor wire assembly 2 is arranged between the wire straightening component 1 and the front lower pressure roller 601, a rear conductor wire assembly 4 is arranged between the rear lower pressure roller 602 and the traction component 5, and a front and rear position wire jumper assembly 7 corresponding to the front lower pressure roller 601 and the rear lower pressure roller 602 is arranged on the rolling component 3, and a middle wire jumper assembly 9 corresponding to the main line roller 10 is arranged.

[0029] Basic principle: A brief description of the flattening process of the enameled round wire is given. The principle is relatively simple. The enameled wire is continuously wound by a traction structure for directional and uniform conduction. During the conduction process of the enameled wire, the corresponding rail pressing mold is used to roll the enameled wire. The rail pressing mold is similar to a rectangular groove structure. The rail pressing mold is made of tungsten steel. The depth and width of the groove are variable. The mold of the corresponding specification is selected according to the size of the round wire to be tested. The enameled round wire enters the rail pressing mold, and the height of the pressing wheel is adjusted (accurate to 0.1mm through servo motor control) and the tension control. After starting, traction (controlled by a stepper motor, stable speed) can complete the flattening test operation, such as rolling the enameled round wire into an enameled flat wire;

[0030] And specifically combined with Figure 1 and Figure 2 To give a brief description, the enameled round wire is firstly flattened by the wire straightening assembly 1, and then enters the middle position of the auxiliary wire roller 8 and the main wire roller 10 one by one, and a corresponding structural shape is formed between the auxiliary wire roller 8 and the main wire roller 10. Figure 4 For example, a plurality of pressure rings corresponding to the enameled round wires are installed on the secondary wire roller 8, and a pressure groove corresponding to the pressure ring is opened on the outer surface of the main wire roller 10. The enameled round wire is mainly located in the pressure groove and is squeezed into a flat wire by the pressure ring. The flattened enameled flat wire is continuously wound by the traction component 5, and the winding action of the traction component 5 also serves as a power source for the conduction of the enameled circle center. This part is a conventional method in the enameled wire flattening process. Specifically, the width and thickness of the enameled flat wire after flattening can be reversely controlled by parameters such as the width of the pressure ring or the spacing of the pressure groove corresponding to the pressure ring.

[0031] Embodiment 2: The following supplementary explanation is given for the rolling action:

[0032] The front and rear jumper assembly 7 and the middle jumper assembly 9 both include a coupling seat, and the front and rear jumper assembly 7 is also provided with a self-inspection working assembly, and the middle jumper assembly 9 is also provided with a main action push cylinder, the front lower pressure roller 601 and the rear lower pressure roller 602 are provided with a height difference in the vertical direction, the coupling seat is arranged at the two end positions of the front lower pressure roller 601, the rear lower pressure roller 602 and the main line roller 10 in a rotating connection manner, and the coupling seat is slidably connected in the vertical direction in the rolling assembly 3, and a driving motor corresponding to the secondary line roller 8 is installed in the rolling assembly 3, the output shaft of the main action push cylinder and the self-inspection working assembly is fixedly connected to the coupling seat in the main line roller 10, and the self-inspection working assembly includes a secondary action push cylinder and a tension sensing structure.

[0033] Solution description: Based on the technical content in the first embodiment, the present invention makes partial process improvements on the conventional flattening process. The obvious difference from the conventional rolling action is that the front lower pressing roller 601 and the rear lower pressing roller 602 are respectively placed on both sides of the auxiliary wire roller 8 and the main wire roller 10 that perform the rolling action. The front lower pressing roller 601 and the rear lower pressing roller 602 do not participate in the rolling action in essence, but only serve as interference components in the conduction process of the enameled wire. Figure 5 To explain:

[0034] S1: In essence, the front lower pressure roller 601 and the rear lower pressure roller 602 also belong to the conductive structure of the enameled wire, but their arrangement method corresponds to the main wire roller 10, as shown in the following example. Figure 5 As shown, the enameled wire passing through the main line roller 10 forms a large arc through the front lower pressing roller 601 and the rear lower pressing roller 602. Specifically, the front lower pressing roller 601 and the rear lower pressing roller 602 both generate downward pressure on the enameled wire. Under the action of the downward pressure jointly generated by the front lower pressing roller 601 and the rear lower pressing roller 602, the main line roller 10 will also indirectly generate a downward movement trend, or generate a greater tension change on the enameled wire passing through the main line roller 10.

[0035] On the contrary, when the main line roller 10 moves in the vertical direction, it will also produce a greater tension change on the enameled wire passing through the main line roller 10, and can also reversely affect the front lower pressure roller 601 and the rear lower pressure roller 602. Figure 3 To explain, both the front and rear lower pressure rollers 601 and 602 are provided with front and rear position jumper assembly 7, and the purpose of the front and rear position jumper assembly 7 is: firstly, the front and rear lower pressure rollers 601 and 602 are adjusted up and down by the auxiliary action push cylinder, and secondly, the tension change generated by the front lower pressure roller 601 or the rear lower pressure roller 602 can be fed back by the tension sensing structure, while the middle jumper assembly 9 only drives the main line roller 10 to adjust in the vertical direction by the main action push cylinder;

[0036] S2: Combined with the technical content description in S1, the winding speed of the traction assembly 5 in the present invention is relatively constant in the winding action, but in the specific operation process, the height difference between the front lower pressure roller 601 and the rear lower pressure roller 602 can be adjusted, and on the basis of adjusting the height difference between the front lower pressure roller 601 and the rear lower pressure roller 602, the main line roller 10 can be further driven to move in the vertical direction. A brief explanation of this is that the main line roller 10 moves up and down mainly to change the thickness of the enameled round wire during the flattening process, and the switching process of the height difference between the front lower pressure roller 601 and the rear lower pressure roller 602 is used to change the winding speed of the enameled round wire when it passes through the rolling action of the main line roller 10;

[0037] by Figure 5For example, the setting position of the front lower pressing roller 601 is lower than the setting position of the rear lower pressing roller 602. In this process, the height difference between the front lower pressing roller 601 and the rear lower pressing roller 602 can be further increased, that is, the front lower pressing roller 601 continues to move downward, then in this process, the stroke of the enameled round wire in the front lower pressing roller 601 is larger, thereby reducing the conduction speed of the enameled round wire when it is on the main line roller 10; on the contrary, if the height of the rear lower pressing roller 602 is lower than the height of the front lower pressing roller 601, the conduction speed of the enameled round wire when it is on the main line roller 10 can be accelerated, but it needs to be limited to:

[0038] It is necessary to ensure that the horizontal plane position of the center point of the front lower pressing roller 601 and the rear lower pressing roller 602 is always lower than the horizontal plane position of the center point of the main line roller 10. When changing the conduction speed of the enameled round wire during the rolling action, the key purpose is to "leave enough time" for the main line roller 10 to adjust the flattening thickness by controlling the flattening time during the flattening process.

[0039] S3: Combined with the technical contents in S1~S2, the thickness of the enameled round wire passing through the main line roller 10 is adjusted by the main action push cylinder in the intermediate jumper assembly 9 when performing the rolling action. First, the preset flattening thickness is set by the main action push cylinder. However, when it continues, there may be an obvious difference between the flattening thickness in the actual state and the preset flattening thickness. This can be indirectly understood as: the process directly affects the setting position of the main line roller 10, thereby indirectly affecting the height difference between the front lower pressure roller 601 and the rear lower pressure roller 602. Therefore, the flattening thickness in the actual flattening process can be directly judged according to the relevant parameters obtained by the tension sensing structure in the front lower pressure roller 601 and the rear lower pressure roller 602, so that the flattening thickness in the actual flattening process can be achieved. The purpose of performing flattening action and self-inspection at the same time.

[0040] Embodiment 3: mainly explains the polymorphic action self-checking model in Embodiment 1:

[0041] Reference Figure 6 In the polymorphic action self-detection model, the tension data in the tension sensing structure is used as a variable, and the traction data in the traction component 5 is used as a quantitative variable to perform a polymorphic action detection process. The polymorphic action detection process is used to obtain the actual flattening state in the rolling action, and cross-linking control commands are sent to the middle jumper component 9 and the front and rear jumper components 7 according to the actual flattening state.

[0042] Solution description: Because the flattening process of enameled round wire includes multiple actions, the key is to use the specific parameters of the main wire roller 10 and the auxiliary wire roller 8 when rolling. The traction component 5 in the overall device needs to maintain the enameled round wire for uniform winding, so its traction data is used as a quantitative method. Figure 5 Take this as an example to illustrate:

[0043] The tension data is mainly used to indicate the tension data FnQ and FnH in the front lower pressure roller 601 and the rear lower pressure roller 602, and further record the height differences LQ and LH of the front lower pressure roller 601 and the rear lower pressure roller 602 relative to the main line roller 10 in the vertical direction. MiZ indicates the flattening thickness in the actual state, and MiO indicates the flattening preset thickness. On the basis of maintaining LQ and LH, and in the ideal state of MiZ=MiO, when the enameled round wire passes through the main line roller 10, it will not have a significant impact on the tension data in the front lower pressure roller 601 and the rear lower pressure roller 602. However, when MiZ>MiO, it indicates that the main line roller 10 has a downward movement trend. On the contrary, when MiZ<MiO, it indicates that the main line roller 10 has an upward movement trend.

[0044] In combination with the above content, it should be noted that: whether it is the state of MiZ>MiO or MiZ<MiO, it will affect the tension data in the front lower pressure roller 601 and the rear lower pressure roller 602. It should be noted that: the thickness of the enameled round wire after flattening is mostly in millimeters, so it is difficult to detect slight thickness changes in time. If ultra-precision detection equipment is used to detect changes in the actual flattening process, it is very easy to cause damage to the ultra-precision detection equipment during the continuous flattening process. Therefore, the present invention does not directly detect the relative displacement of the main line roller 10, but specifically detects the changes in the tension data in the front lower pressure roller 601 and the rear lower pressure roller 602, and is expressed as follows:

[0045] State 1: When MiZ<MiO, because it is difficult for the main line roller 10 and the auxiliary line roller 8 to flatten the enameled round wire, the conduction speed of the enameled round wire passing through the main line roller 10 is reduced, but the traction data is relatively constant, then the enameled flat wire on the right side of the main line roller 10 generates a greater tension on the rear lower pressure roller 602, causing the rear lower pressure roller 602 to move upward, while the tension generated by the front lower pressure roller 601 is reduced;

[0046] State 2: When MiZ>MiO, because the main line roller 10 and the auxiliary line roller 8 can flatten the enameled round wire more easily, the tension changes in the front lower pressure roller 601 and the rear lower pressure roller 602 will be reduced.

[0047] Combining the above-mentioned state one and state two, the actual state of flattening in the rolling action can be directly judged, and the actual state of flattening only represents MiZ, and the subsequent cross-linking control command is mainly used to change the movement process of the front lower pressure roller 601, the main line roller 10 and the rear lower pressure roller 602 along Z1, Z2 and Z3, and combined with LQ, LH as the basis, and adjust LQ, LH according to the changes of FnQ, FnH, and finally adjust the position of the main line roller 10 according to the preset process parameters. This part is not described in detail in the present invention.

[0048] In summary: for the flattening process of the enameled round wire, in order to ensure the flattening amount, local optimization and improvement are carried out for the rolling action. The conventional after-the-fact detection method is abandoned, and the front lower pressing roller and the rear lower pressing roller are added for the specific rolling action. The position of the main line roller is not monitored in real time. On the contrary, the actual state of the flattening in the rolling action is indirectly fed back through the change of the tension data of the front lower pressing roller and the rear lower pressing roller relative to the enameled round wire or the enameled flat wire. Specifically, according to the tension data at the corresponding front lower pressing roller and the rear lower pressing roller on both sides, whether there is a flattening amount deviation when the enameled round wire is flattened can be directly fed back in real time to avoid affecting the production efficiency of the whole line.
