Description

Technical Field

[0001] The invention relates to a stainless steel wire length detection device, in particular to a stainless steel wire length detection device applied in the field of length measuring devices. Background Art

[0002] Steel wire is one of the four major types of steel: plates, tubes, profiles, and wires. It is a reprocessed product made from hot-rolled wire rods by cold drawing. It is relatively long and is usually coiled up or directly wrapped around the outside of a rod to shape it during production and storage. Its specific length is difficult to detect using traditional length detection methods.

[0003] The utility model patent CN220250897U specification discloses a U-shaped steel wire length detection device, which can measure the length of the U-shaped steel wire and can automatically reset after the measurement is completed. At the same time, it can be adjusted according to the width of the steel wire, so that the device can adapt to the measurement needs of different steel wires. It is simple to operate and highly practical.

[0004] In the above utility model, the disclosed U-shaped steel wire length detection device is also a steel wire detection structure for non-linear states, but it is only applicable to non-linear steel wires with shorter lengths and cannot detect steel wires with longer lengths, making it difficult to achieve the purpose of length detection of extra-long steel wires. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that the existing steel wire detection structure is only applicable to non-linear steel wires of shorter lengths, and cannot detect steel wires of longer lengths, making it difficult to achieve the purpose of length detection of extra-long steel wires.

[0006] In order to solve the above problems, the present invention provides a stainless steel wire length detection device, comprising a winding unit, a steel wire is sleeved on the winding unit, a contact point is fixedly connected to the inner wall of the winding unit, the winding unit comprises a ceramic substrate, a notch groove is cut on the side wall of the ceramic substrate at one end away from the contact point, one end of the steel wire penetrates the winding unit and extends to the contact point, the other end of the steel wire penetrates the notch groove and extends to the side of the winding unit away from the contact point, the contact point comprises a contact body, a separation membrane is fixedly connected to the inner wall of the contact body, the internal space of the contact body is divided into a connecting part and a transition part from bottom to top by the separation membrane, the end of the steel wire close to the contact contact penetrates the transition part and the separation membrane in turn and extends to the connecting part, the connecting part is filled with an air-hardening gel material, a positioning groove matching the size of the steel wire is cut on the bottom plate of the connecting groove, and the end of the steel wire close to the contact contact extends into the positioning groove;

[0007] One end of the steel wire away from the contact point is fixedly connected to a detection device, one end of the detection device away from the steel wire is electrically connected to a detection resistor, one end of the detection resistor away from the detection device is fixedly connected to a detection power supply, and one end of the detection power supply away from the detection resistor is fixedly connected to a contact contact.

[0008] In the above-mentioned stainless steel wire length detection device, the purpose of conveniently detecting the length of the extra-long steel wire is achieved.

[0009] As a further improvement of the present application, a reinforcing net is embedded in the separator membrane. The reinforcing net is woven from high-toughness fibers to increase the structural strength of the separator membrane, so that the separator membrane is not easily torn on a large scale after being punctured by a steel wire, and the sealing effect of the separator membrane is not easily affected.

[0010] As a further improvement of the present application, a plurality of elastic fibers are fixedly connected to the upper end of the separation membrane, and the plurality of elastic fibers overlap each other to form a three-dimensional structure, which can effectively prevent the large-scale diffusion of the air-hardening gel material and is not easily affected in its solidification and sealing effect.

[0011] As a further improvement of the present application, the detection resistor must maintain maximum resistance when connected to the circuit and gradually reduce it during the detection process. When the reading of the detection equipment changes rapidly, the reading is detected again, and the resistance of the detection resistor connected to the detection circuit is controlled to be close to the resistance of the steel wire, thereby reducing the impact of system errors on the detection results. At the same time, the resistance value of the detection resistor can be adjusted, and multiple groups of data can be measured, and the average value is taken as the final result of the steel wire length.

[0012] As another improvement of the present application, a standard unit matching itself is placed in the notch groove, the standard unit includes matching shell one and shell two, and the steel wire passes through shell one and shell two, countersunk grooves are inserted in shell one and shell two, two conductive rods respectively pass through shell one and shell two and contact with the steel wire, one end of shell one close to shell two is fixedly connected with magnetic ring one, one end of shell two close to shell one is fixedly connected with magnetic ring two, and magnetic ring one is adsorbed with magnetic ring two, and a compression spring is fixedly connected between shell one and shell two, and the standard unit can be used to detect the resistance of the steel wire per unit length to determine the standard resistance of the steel wire as a standard parameter for subsequent detection.

[0013] As another improvement supplement of the present application, countersunk grooves matching the positions of the conductive rods are respectively bored on the shell one and the shell two, and rubber pads are connected between the shell one and the shell two and the steel wire. The rubber pads have an interference fit with the steel wire. The boring of the countersunk grooves facilitates the connection of the standard unit to the detection circuit, and the rubber pads can increase the friction between the standard unit and the steel wire after the compression spring returns to its original state. During the standard unit resistance detection process, the standard unit is not easy to slide and is not easy to affect the detection results.

[0014] As another improvement supplement of the present application, an end of shell two close to shell one is fixedly connected to a marking shell, an end of shell one close to shell two is fixedly connected to an indicator shell, and the indicator shell is sleeved on the outside of the marking shell, thereby increasing the overall sealing effect of the standard unit and preventing oxidation at the scratched insulating coating on the surface of the steel wire during the standard unit detection process.

[0015] As another improved supplement of the present application, scale lines are engraved on the marking shell, and the scale lines change color intervals in centimeters, which is convenient for testers to verify the unit length of the standard unit and also can make fine adjustments to the unit length.

[0016] In summary, the detection power supply and the detection resistor constitute the detection circuit of the steel wire. After the steel wire is connected to the detection circuit, the resistance of the steel wire can be detected. When the resistance of the steel wire is related to its own material and diameter, it is only proportional to its own length. When the steel wire is produced, the resistance per unit length of the steel wire is detected and indicated in the parameters. The length of the steel wire can be determined by the measured resistance value. The length detection device in this application is mainly used when the length of the steel wire needs to be detected before packaging after the steel wire is produced. The length of the steel wire can be detected without completely disassembling the steel wire from the winding unit. After a part of the steel wire has been used, the length of the remaining steel wire wound on the winding unit can be detected.

[0017] At the same time, after the steel wire pierces the separator membrane, part of the air-hardening gel material will flow out through the gap between the steel wire and the separator membrane, and enter the transition part under the extrusion of the steel wire and harden and solidify to achieve sealing, ensuring that the contact point and the steel wire connection maintain an oxygen-free environment. The connection between the steel wire and the contact contact is not easy to generate a rust layer, and it is not easy to cause a significant impact on the detection of resistance. The standard unit can be used to detect the resistance of the steel wire per unit length to determine the standard resistance of the steel wire as a standard parameter for subsequent detection.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-4A stainless steel wire length detection device is shown, comprising a winding unit 1, a steel wire 2 is sleeved on the winding unit 1, a contact point 3 is fixedly connected to the inner wall of the winding unit 1, the winding unit 1 comprises a ceramic substrate 101, a notch groove 102 is cut on the side wall of the ceramic substrate 101 at one end away from the contact point 3, one end of the steel wire 2 passes through the winding unit 1 and extends to the contact point 3, the other end of the steel wire 2 passes through the notch groove 102 and extends to the side of the winding unit 1 away from the contact point 3, and the contact point 3 comprises a contact point 102. The contact body 301 has a separator 303 fixedly connected to the inner wall of the contact body 301. The inner space of the contact body 301 is divided into a connection part and a transition part from bottom to top by the separator 303. The end of the steel wire 2 close to the contact point 3 passes through the transition part and the separator 303 in sequence and extends into the connection part. The connection part is filled with an air-hardening gel material. A positioning groove 304 matching the size of the steel wire 2 is cut on the bottom plate of the connecting groove 302, and the end of the steel wire 2 close to the contact point 3 extends into the positioning groove 304.

[0033] See also Fig.10 One end of the steel wire 2 away from the contact contact 3 is fixedly connected to a detection device 7, which is preferably an intelligent multimeter. One end of the detection device 7 away from the steel wire 2 is electrically connected to a detection resistor 6, and one end of the detection resistor 6 away from the detection device 7 is fixedly connected to a detection power supply 5, and one end of the detection power supply 5 away from the detection resistor 6 is fixedly connected to the contact contact 3.

[0034] In the present application, the detection power supply 5 and the detection resistor 6 constitute a detection circuit for the steel wire 2. After the steel wire 2 is connected to the detection circuit, the resistance of the steel wire 2 can be detected. When the resistance of the steel wire 2 is related to its own material and diameter, it is only proportional to its own length. When the steel wire 2 is produced, the resistance per unit length of the steel wire 2 is detected and indicated in the parameters. The length of the steel wire 2 can be determined by the measured resistance value. In particular, the length detection device for the steel wire 2 of the present application is suitable for steel wires with insulating coatings on the surface, and the contact contacts 3 are fixedly connected. One end of the steel wire 2 is a fixed end, and the end of the steel wire 2 away from the contact contact 3 is a taking end, and the contact body 301 is made of conductive material, and the steel wire 2 is electrically connected to the contact contact 3. The length detection device in the present application is mainly used when the length of the steel wire 2 needs to be detected before packaging after it is produced. The length of the steel wire 2 can be detected without completely disassembling the steel wire 2 from the winding unit 1. After a part of the steel wire 2 is used, the length of the remaining steel wire 2 wound on the winding unit 1 can also be detected.

[0035] In addition, in the present application, after the steel wire 2 pierces the separator membrane 303, part of the air-hardening gel material will flow out through the gap between the steel wire 2 and the separator membrane 303, and enter the transition portion and harden and solidify under the extrusion of the steel wire 2, thereby achieving sealing and ensuring that the connection between the contact contact 3 and the steel wire 2 maintains an oxygen-free environment. It is not easy for a rust layer to form at the connection between the steel wire 2 and the contact contact 3, and it is not easy to have a significant impact on the detection of resistance.

[0036] See also Figure 4-5 A reinforcing net is embedded in the separator 303. The reinforcing net is woven from high-tenacity fibers to increase the structural strength of the separator 303, so that the separator 303 is not easily torn on a large scale after being punctured by the steel wire 2, and the sealing effect of the separator 303 is not easily affected. A plurality of elastic fibers 305 are fixedly connected to the upper end of the separator 303. The plurality of elastic fibers 305 overlap each other to form a three-dimensional structure, which can effectively prevent the large-scale diffusion of the air-hardening gel material and is not easily affected in its solidification and sealing effect.

[0037] See also Fig.10 , the detection resistor 6 must maintain the maximum resistance when connected to the circuit and gradually reduce it during the detection process. When the reading of the detection device 7 changes rapidly, the reading detection is performed again, and the resistance of the detection resistor 6 connected to the detection circuit is controlled to be close to the resistance of the steel wire 2, reducing the impact of the system error on the detection result. At the same time, the resistance value of the detection resistor 6 can be adjusted, and multiple groups of data are measured, and the average value is taken as the final result of the length of the steel wire 2.

[0038] In particular, the dimensions of each structure of the present scheme are not drawn strictly according to the proportions, and those skilled in the art can draw them according to the actual situation. This is a common technology for those skilled in the art, so it is not disclosed in detail in this application. The installation, function and control methods of each electrical structure are also common technologies for those skilled in the art.

[0039] The second implementation method:

[0040] Figure 6-9A stainless steel wire length detection device is shown, in which a standard unit 4 matching the standard unit 4 is placed in the notch groove 102, and the standard unit 4 includes a matching shell 1 401 and a shell 2 402, and the steel wire 2 passes through the shell 1 401 and the shell 2 402, and the shell 1 401 and the shell 2 402 are both plugged with countersunk grooves 404, and two conductive rods 403 respectively pass through the shell 1 401 and the shell 2 402 and contact the steel wire 2, and the position where the conductive rod 403 contacts the steel wire 2 will scratch the insulating coating on the surface of the steel wire 2, and the shell 1 401 is close to the outer shell 401. One end of the second shell 402 is fixedly connected to a magnetic ring 1 405, and one end of the second shell 402 close to the first shell 401 is fixedly connected to a magnetic ring 2 406, and the magnetic ring 1 405 and the magnetic ring 2 406 are attracted to each other, and a compression spring is fixedly connected between the first shell 401 and the second shell 402. In this application, the standard unit 4 can be used to detect the resistance memory of the steel wire 2 per unit length to determine the standard resistance of the steel wire 2, wherein the adsorption force of the magnetic ring 1 405 and the magnetic ring 2 406 is greater than the pressure generated by the deformation of the compression spring. When stored, the standard unit 4 as a whole is Figure 8 As shown, it is convenient for storage. When in use, after the housing 1 401 is separated from the housing 2 402, the adsorption force of the magnetic ring 1 405 and the magnetic ring 2 406 is less than the pressure generated by the deformation of the compression spring, and the magnetic ring 1 405 and the magnetic ring 2 406 are stretched to the standard unit length under the compression spring, and the two conductive rods 403 are connected to replace Fig.10 The positions of the steel wire 2 and the contact point 3 shown are used to detect the resistance per standard unit length of the steel wire 2 as a standard parameter for subsequent detection. At the same time, those skilled in the art can improve the accuracy of the standard parameter by taking the average through multiple tests.

[0041] The first shell 401 and the second shell 402 are respectively provided with countersunk grooves 404 matching the positions of the conductive rods 403. The first shell 401 and the second shell 402 are connected with rubber pads 407 between the steel wire 2. The rubber pads 407 and the steel wire 2 have an interference fit. The countersunk grooves 404 are provided to facilitate the connection of the standard unit 4 to the detection circuit. The rubber pads 407 can increase the friction between the standard unit 4 and the steel wire 2 after the compression spring is restored to its original state. In the process of standard unit resistance detection, the standard unit 4 is not easy to slide and is not easy to affect the detection result. The second shell 401 is provided with a rubber pad 407. 02 is fixedly connected to one end of the shell 1 401 with a marking shell 409, and is fixedly connected to one end of the shell 1 401 close to the shell 2 402 with an indicator shell 408, and the indicator shell 408 is sleeved on the outside of the marking shell 409, thereby increasing the overall sealing effect of the standard unit 4. During the standard unit inspection process, it is not easy to cause oxidation at the scratched insulating coating on the surface of the steel wire 2. Scale lines are engraved on the marking shell 409, and the color of the scale lines changes in centimeters, which is convenient for inspectors to verify the unit length of the standard unit 4 and also can make fine adjustments to the unit length.

[0042] Compared with the first embodiment, the present embodiment discloses a standard unit 4 for detecting the resistance of the standard unit length of the steel wire 2 as a standard parameter for subsequent detection. At the same time, those skilled in the art can improve the accuracy of the standard parameter by taking the average through multiple tests.

[0043] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
