Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of enameled wire processing and relates to a wire breakage monitoring device for enameled wire processing and application thereof. Background Art
[0002] During the enameled wire processing, the wire is repeatedly drawn and annealed to the specified size, and then painted and baked multiple times. The wire is in a continuous pulling state during the whole process. Wire break monitoring is a protective measure set up to determine wire break failures. The existing wire break monitoring method is mainly infrared monitoring, that is, a threading die is set up to pass the wire through the die hole to determine a necessary path for the wire to pass through, and then an infrared probe is set at the necessary path. When the wire breaks, the disappearance of the wire on the necessary path is detected by infrared and an alarm is sounded. Each time a wire break occurs, the wire needs to be re-pulled, and there is a large amount of wire pollution and waste. This is a more serious negative factor in processing efficiency and cost increase in the enameled wire processing process. Summary of the Invention
[0003] The purpose of the present invention is to provide a wire breakage monitoring device for enameled wire processing in order to solve the above problems existing in the prior art. The technical problem to be solved by the present invention is how to achieve wire clamping after wire breakage.
[0004] The object of the present invention can be achieved through the following technical solutions: A wire breakage monitoring device for enameled wire processing, characterized in that it includes a mounting seat, a wire clamping cone fixed on the mounting seat and a wire clamping cylinder sleeved on the wire clamping cone, the wire clamping cone including a connecting portion with the mounting seat and a cone head located on the connecting portion, the wire clamping cylinder including a wire clamping portion adapted for the cone head and a head portion located above the wire clamping portion, the top of the head portion having a wire threading hole adapted for the wire diameter, the wire clamping cone having an air inlet channel, the inlet of the air inlet channel being located at the connecting portion, the outlet of the air inlet channel being located at the top of the cone head, the inlet of the air inlet channel being connected to an air source, the cone head having a cone surface tangent being in the same straight line as the wire threading hole, allowing the wire to pass straight through the gap between the cone head and the wire clamping cone after passing through the wire threading hole as the wire threading channel; the wire pulling method is: entering the head portion from the wire threading hole, then passing through the wire threading channel, and finally pulling out.
[0005] The difference from the traditional method is that: when the wire passes through the threading hole, the ventilation cross-section of the threading hole is greatly reduced, and the air pressure in the chamber formed between the wire clamping barrel and the cone head is relatively high, thereby realizing air flotation of the wire clamping barrel. The airflow path is: an airflow of a certain pressure enters from the air inlet channel. Due to the large exhaust resistance at the threading hole, the airflow returns and is discharged from the gap between the wire clamping barrel and the cone head. When the wire breaks in the front and the wire leaves the threading hole, the wire end is located in the hidden head. At this time, the flow cross-section of the threading hole increases suddenly, and the airflow can flow out of the threading hole with a larger flow rate. The air pressure in the chamber enclosed by the wire clamping barrel and the cone head decreases. Under the action of gravity, the gap between the wire clamping barrel and the cone head is reduced, thereby clamping the wire that is still in the threading channel, thereby realizing the clamping of the wire end after the wire breaks in the rear during the wire traction process.
[0006] Furthermore, the connecting portion is provided with a pressure sensor, and the pressure sensor can be triggered when the gap between the clamping barrel and the cone head is reduced.
[0007] After the wire is broken and the wire end is clamped, the pressure sensor can be triggered to provide on-duty information of the broken wire fault.
[0008] Furthermore, a counterweight block is sleeved on the wire clamping cylinder.
[0009] Increasing or decreasing the weight of the counterweight and adjusting the air intake parameters are two means of regulating the working performance of the wire break monitoring device. They can be performed one by one or used together, thereby achieving lossless wire passing before wire breakage and timely wire clamping after wire breakage. The size of the counterweight is more directly used to regulate the appropriate wire clamping pressure.
[0010] Furthermore, the cone head is in the shape of a cone column, and the tangent line of the cone surface on the cone head that is in the same straight line as the threading hole is vertical.
[0011] Since the cone head is in a cone shape, and the wire threading channel is in a vertical state, and the threading hole and the threading channel are in the same straight line, the center of gravity of the wire clamping barrel is inclined toward the side of the wire clamping barrel's geometric center close to the threading channel. In other words, in the normal wiring state, under the action of the gravity of the wire clamping barrel, the gap between the wire clamping barrel and the cone head away from the threading channel is smaller, while the gap between the wire clamping barrel and the cone head where the threading channel is located is larger. This setting determines the basic position of the wire clamping barrel in the air-floating state, which can ensure that the wire passing space of the threading channel will not be increased or decreased due to the air-floating of the wire clamping barrel, eliminating the problem of the wire clamping barrel in the air-floating state. The uncertainty of the position of the wire clamp ensures that the wire is not worn during the threading process. Furthermore, more airflow passes through the threading channel of the wire, which has a higher utilization rate when the airflow is used to clean the wire, dry the wire, cool the wire, etc. In addition, the airflow also has a certain "lubricating" and protective effect on the passage of the wire itself, reducing the resistance to the wire passing through. Finally, since the gap between the wire clamp and the cone head is more reflected near the threading channel, compared with the cone structure with the axis in a vertical state, the wire clamp can clamp the wire with a smaller downward displacement, thereby improving the response sensitivity of the wire clamp.
[0012] Furthermore, the connecting portion has an escape portion located below the threading channel.
[0013] As its application scenario, one of the options is: the wire breakage monitoring device is used on the traction path after the wire is cleaned, and uses airflow to dehydrate and dry the wire.
[0014] After drawing, the wire is washed with water to remove the copper chips and other slag residues on the wire, and then air-dried to achieve dehydration and remove the remaining residues again. This is an inevitable process in existing operations. However, in this solution, the wire breakage monitoring device can be used to achieve air drying after washing, achieving dual purposes.
[0015] As its application scenario, one of the options is: the wire breakage monitoring device is used on the traction path after the wire is drawn, and uses airflow to cool the wire.
[0016] Cooling down after drawing is beneficial to the recovery of the physical properties of the wire and maintaining the density of the material after drawing. In the existing process, the wire is immediately air-cooled after drawing. The wire breakage monitoring device can serve as wire breakage monitoring and air cooling after drawing, serving two purposes in one.
[0017] As its application scenario, one of the options is: multiple wire breakage monitoring devices are set in series on the wire pulling path during the enameled wire processing process, and the wires clamped by the wire breakage monitoring devices are the wires before painting and the wires after the paint film is dried.
[0018] Based on the characteristics of this wire breakage monitoring device, it can be applied to other traction paths except when the paint is not cured and the device cannot be used for wire breakage monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.
[0025] like Figure 1 、 Figure 2 and Figure 3 As shown, the wire breakage monitoring device for enameled wire processing includes a mounting base 1, a wire clamping cone 2 fixed on the mounting base 1, and a wire clamping barrel 3 sleeved on the wire clamping cone 2. The wire clamping cone 2 includes a connecting portion with the mounting base 1 and a cone head 21 located above the connecting portion. The wire clamping barrel 3 includes a wire clamping portion 31 adapted to the cone head 21 and a head portion 32 located above the wire clamping portion 31. The top of the head portion 32 has a wire threading hole 33 adapted to the diameter of the wire. The wire clamping cone 2 has an air inlet channel 23. The entrance of the air intake channel 23 is located at the connecting part, and the outlet of the air intake channel 23 is located at the top of the cone head 21. The entrance of the air intake channel 23 is connected to the air source. The cone head 21 has a cone tangent that is in the same straight line as the threading hole 33. The threading path that allows the wire to pass straight through the gap between the cone head 21 and the wire clamping cone 2 after passing through the threading hole 33 is the threading channel of the wire. The wire is pulled in the following way: from the threading hole 33 into the head portion 32, then through the threading channel, and finally pulled out.
[0026] The difference from the traditional method is that when the wire passes through the threading hole 33, the ventilation cross section of the threading hole 33 is greatly reduced, and the air pressure in the chamber formed between the clamping cylinder 3 and the cone head 21 is relatively high, so the wire clamping cylinder 3 is floated. The air flow path is as follows: Figure 3As shown in the figure: the airflow with a certain pressure enters from the air inlet channel 23. Due to the large exhaust resistance at the threading hole 33, the airflow returns and is discharged from the gap between the clamping barrel 3 and the cone head 21. When the wire is broken in the front and the wire is out of the threading hole 33, the airflow path is as follows Figure 4 As shown, when the wire end is located in the storage head 32, the flow cross-section of the threading hole 33 increases suddenly, and the air flow can flow out of the threading hole 33 at a larger flow rate. The air pressure in the chamber enclosed by the wire clamping barrel 3 and the cone head 21 decreases. Under the action of gravity, the gap between the wire clamping barrel 3 and the cone head 21 is reduced, thereby clamping the wire that is still in the threading channel, and realizing the clamping of the wire end after the wire is broken at the rear during the wire pulling process.
[0027] A pressure sensor 4 is provided on the connection part, and the pressure sensor 4 can be triggered when the gap between the clamping barrel 3 and the cone head 21 is reduced. After the wire is broken and the wire head is clamped, the pressure sensor 4 can be triggered to provide duty information of the broken wire fault.
[0028] A counterweight 5 is mounted on the clamping barrel 3. Adjusting the counterweight and the air intake parameters are two methods for controlling the performance of the wire breakage monitoring device. These can be performed either individually or in combination, enabling lossless wire feeding before a break and timely clamping after a break. The size of the counterweight is used more directly to control the appropriate clamping pressure. During the debugging phase, ensure that the wire passes smoothly and that the threading hole 33 has adequate clamping force when no wire passes through. Once debugging is complete, begin operation.
[0029] The cone head 21 is in the shape of a cone, and the tangent of the cone surface on the cone head 21 that is in the same straight line as the threading hole 33 is vertical. Since the cone head 21 is in the shape of a cone, and the threading channel of the wire is in a vertical state, and the threading hole 33 is in the same straight line as the threading channel, the center of gravity of the wire clamp 3 is tilted toward the side of the wire clamp 3 that is close to the threading channel. In other words, in the normal wiring state, under the action of the gravity of the wire clamp 3, the gap between the wire clamp 3 and the cone head 21 away from the threading channel is smaller, while the gap between the wire clamp 3 and the cone head 21 where the threading channel is located is larger. This setting determines the basic position of the wire clamp 3 in the air-floating state, which can ensure that the wire passing space of the threading channel will not be larger or smaller due to the air-floating of the wire clamp 3, eliminating the problem of the wire clamp 3 being in the air-floating state. The uncertainty of the position of the wire clamping barrel 3 in the air-floating state ensures that the wire is not worn during the threading process. Furthermore, more airflow passes through the threading channel of the wire, which has a higher utilization rate when the airflow is used to clean the wire, dry the wire, cool the wire, etc. In addition, the airflow also has a certain "lubricating" and protective effect on the passage of the wire itself, reducing the resistance to the wire passing. Finally, since the gap between the wire clamping barrel 3 and the cone head 21 is more reflected near the threading channel, compared with the cone structure with the axis in the vertical state, the wire clamping barrel 3 can clamp the wire with a smaller downward displacement, thereby improving the response sensitivity of the wire clamping.
[0030] The connecting portion is provided with a relief portion 22 below the threading channel. The relief portion 22 ensures that the wire can pass through without interference after being pulled out of the wire clamping barrel 3, making it easy to operate.
[0031] One possible application scenario is for the device to be used on the wire drawing path after cleaning, utilizing airflow to dehydrate and dry the wire. After drawing, the wire is washed to remove residual copper and other slag, and then air-dried to dehydrate and remove any remaining residue. This is an inevitable process in existing operations. However, in this solution, the device can be used to air-dry the wire after washing, achieving dual purposes.
[0032] One possible application scenario is for the device to be used on the wire drawing path after wire drawing, utilizing airflow to cool the wire. Cooling after drawing helps restore the wire's physical properties and maintain the material's compactness. While conventional processes involve air cooling immediately after wire drawing, this device can serve both post-drawing monitoring and post-drawing cooling functions, effectively serving two purposes.
[0033] One possible application scenario involves installing multiple wire breakage monitoring devices in series along the wire traction path during enameled wire processing, with the devices clamping wires before and after the paint film has dried. Due to the characteristics of this wire breakage monitoring device, it can be used for wire breakage monitoring in all traction paths, except when the paint film is not cured.
[0034] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
