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, it is repeatedly drawn and annealed to the specified size, and then painted and baked many times. During the whole process, the wire is in a continuous pulling state. Wire break monitoring is a protective measure set up to judge the wire break failure. The existing wire break monitoring method is mainly infrared monitoring, that is, a threading mold is set to make the wire pass through the mold 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 is broken, the disappearance of the wire on the necessary path is detected by infrared and an alarm is sounded. Each time a wire break failure occurs, the wire needs to be re-pulled, and there is a large amount of wire pollution and waste, which 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 view of the above-mentioned 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 to the cone head and a head portion located on the wire clamping portion, the top of the head portion having a threading hole adapted to the diameter of the wire, 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 that is in the same straight line as the threading hole, allowing the wire to pass straight through the gap between the cone head and the wire clamping cone after passing through the threading hole as the threading path of the wire; the wire is pulled in a manner of: entering the head portion from the threading hole, then passing through the threading channel, and finally being pulled 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, so that the wire clamping barrel is flotated. The air flow path is: an air flow with a certain pressure enters from the air inlet channel. Due to the large exhaust resistance at the threading hole, the air flow 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 is separated from the threading hole, the wire head is located in the hiding head. At this time, the flow cross-section of the threading hole increases suddenly, and the air flow 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 achieving the clamping of the wire head 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 cylinder and the cone head is reduced.

[0007] After the wire is broken and the wire head is clamped, the pressure sensor can be triggered to provide 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 cone-shaped, and the wire threading channel is vertical, and the threading hole is in the same straight line with the threading channel, the center of gravity of the wire clamp barrel is inclined toward the side of the wire clamp 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 clamp barrel, the gap between the wire clamp barrel and the cone head away from the threading channel is smaller, while the gap between the wire clamp barrel and the cone head where the threading channel is located is larger. This setting determines the basic position of the wire clamp 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 clamp barrel, eliminating the problem of the wire clamp 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, dry, and cool the wire. In addition, the airflow also has a certain "lubricating" and protective effect on the passage of the wire itself, reducing the resistance to the passage of the wire. 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 the airflow is used to dehydrate and dry the wire.

[0014] After drawing, the wire will be washed with water to remove the copper chips and other slag chips remaining 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 break 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 the airflow is used to cool the wire.

[0016] The cooling after drawing is beneficial to the recovery of the physical properties of the wire and the maintenance of 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 after drawing 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 arranged 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 after painting.

[0018] Based on the characteristics of the wire breakage monitoring device, it can be applied to other traction paths except that the device cannot be used for wire breakage monitoring when the paint is not cured. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution 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 comprises a mounting seat 1, a wire clamping cone 2 fixed on the mounting seat 1, and a wire clamping cylinder 3 sleeved on the wire clamping cone 2, the wire clamping cone 2 comprises a connecting portion with the mounting seat 1 and a cone head 21 located on the connecting portion, the wire clamping cylinder 3 comprises a wire clamping portion 31 adapted to the cone head 21 and a head portion 32 located on the wire clamping portion 31, the top of the head portion 32 has a threading hole 33 adapted to the diameter of the wire, and the wire clamping cone 2 has an air inlet channel 23, The entrance of the air inlet channel 23 is located at the connecting part, and the exit of the air inlet channel 23 is located at the top of the cone head 21. The entrance of the air inlet 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: enter the storage head 32 from the threading hole 33, then pass through the threading channel, and finally be 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 large, so that the clamping cylinder 3 is air-floated, and 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 until the wire is separated from the threading hole 33, the airflow path is as follows Figure 4 As shown, when the thread 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 cylinder 3 and the cone head 21 decreases. Under the action of gravity, the gap between the wire clamping cylinder 3 and the cone head 21 is reduced, thereby clamping the wire that is still in the threading channel, thereby achieving 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 wire breakage fault.

[0028] The clamping barrel 3 is provided with a counterweight 5. Increasing or decreasing the counterweight and adjusting the air intake parameters are two means of regulating the working performance of the wire break monitoring device. One or the other can be selected or used together, so as to achieve 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. During the debugging stage, it should be ensured that the wire passes smoothly and the threading hole 33 has an appropriate clamping force on the wire when no wire passes through. After the debugging is completed, the operation begins.

[0029] The cone head 21 is in the shape of a cone column, and the cone tangent 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 column, and since 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 clamping barrel 3 is inclined toward the side of the wire clamping barrel 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 clamping barrel 3, the gap between the wire clamping barrel 3 and the cone head 21 away from the threading channel is smaller, while the gap between the wire clamping barrel 3 where the threading channel is located and the cone head 21 is larger. This setting determines the basic position of the wire clamping barrel 3 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 3, eliminating the problem of the wire clamping barrel 3 being in a state of ... The uncertainty of the position of the wire clamping cylinder 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, dry, and cool the wire. In addition, the airflow also has a certain "lubricating" and protective effect on the wire itself, reducing the resistance to the wire passing. Finally, since the gap between the wire clamping cylinder 3 and the cone head 21 is more reflected near the threading channel, compared with the cone cylinder structure with the axis in a vertical state, the wire clamping cylinder 3 can clamp the wire with a smaller downward displacement, thereby improving the reaction sensitivity of the clamping wire.

[0030] The connecting part is provided with an escape portion 22 below the threading passage. The escape portion 22 ensures that the wire can pass through without interference after being pulled out of the clamping barrel 3, which is convenient for operation.

[0031] As its application scenario, one of the optional options is: the wire breakage monitoring device is used on the traction path after the wire is cleaned, and the airflow is used to dehydrate and dry the wire. After the wire is drawn, it will be washed with water to remove the copper chips and other slags remaining 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.

[0032] As its application scenario, one of the options is: the wire break monitoring device is used on the traction path after the wire is drawn, and the airflow is used to cool the wire. The cooling after drawing is conducive 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 will be air-cooled immediately after drawing. The wire break monitoring device can be used for wire break monitoring and air cooling after drawing, serving two purposes.

[0033] As its application scenario, one of the options is: multiple wire breakage monitoring devices are arranged 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 and solidified. Based on the characteristics of this wire breakage monitoring device, except that the device cannot be used for wire breakage monitoring when the paint is not solidified, it can be applied to other pulling paths.

[0034] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
