Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment of metal wire, and more particularly to an on-line detection device for the annealing degree of metal wire and a monitoring method thereof. Background Art

[0002] Enameled wire is a main variety of winding wire, which consists of a conductor and an insulating layer. After the bare wire is annealed and softened, it is coated with paint and baked multiple times. However, it is not easy to produce products that meet both the standard requirements and the customer requirements. It is affected by factors such as raw material quality, process parameters, production equipment, and environment. Therefore, the quality characteristics of various enameled wires are different, but they all have four major properties: mechanical properties, chemical properties, electrical properties, and thermal properties.

[0003] During the cold working process of metal wire, plastic deformation occurs, the crystal lattice is distorted and deformed, the grains are sheared and slipped, and the grains are elongated, resulting in cold work hardening, which makes the strength and ductility of the metal wire poor. Therefore, annealing treatment needs to be carried out in the intermediate process or the final process to reorganize the metal lattice, eliminate stress, and improve the ductility of the metal wire. At present, tensile tests are carried out by sampling, and the annealing degree is judged by indexes such as the elongation at break of the metal wire. Truncating the sample is a great waste for the continuous production of wire, and it can only be sampled and cannot be fully inspected, so it cannot fully guarantee whether the annealing quality of the entire production process is consistent.

[0004] Therefore, it is necessary to develop an on-line detection device for the annealing degree of metal wire without truncating the sample. Summary of the Invention

[0026] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below with reference to specific drawings.

[0027] Example 1

[0028] Referring to Figure 1-2 As shown in FIG. 1, an on-line detection device for the annealing degree of metal wire includes: a wire feeding roller 100, a stretching roller 200, and an induction component 300. The wire feeding roller 100 and the stretching roller 200 move synchronously. The ratio of the circumference of the stretching roller 200 to the circumference of the wire feeding roller 100 is 1.001:1 to 1.01:1. The induction component 300 is located between the wire feeding roller 100 and the stretching roller 200. The wire 99 is conveyed by the wire feeding roller 100, passes through the induction component 300, and then is stretched by the stretching roller 200. The pressure generated when the wire 99 passes through the induction component 300 is obtained, and a stress measurement curve of the annealing degree of the wire 99 is formed. Among them, the ratio of the circumference of the stretching roller 200 to the circumference of the wire feeding roller 100 in the present invention is 1.005:1. Since the circumference of the stretching roller 200 is slightly larger than the circumference of the wire feeding roller 100, when the stretching roller 200 and the wire feeding roller 100 are moving synchronously, the wire 99 will be stretched and deformed. At this time, the wire 99 generates a certain pressure on the induction component 300, and the annealing degree of the metal wire 99 can be measured.

[0029] The induction component 300 in the present invention includes a fixed seat 301, a floating bearing seat 302, a pressure sensor 303, and an induction roller 304. The induction roller 304 is installed on the floating bearing seat 302, the floating bearing seat 302 is installed on the fixed seat 301, and the pressure sensor 303 is located below the floating bearing seat 302 to monitor the pressure when the wire 99 passes by.

[0030] The stretching roller 200 in the present invention is fixed on the driving wheel 210 driven by the servo motor 400 through a bearing seat, and the wire feeding roller 100 is fixed on the driven wheel 110 through a bearing seat. The driving wheel 210 and the driven wheel 110 are connected by a synchronous belt 510. Driven by the servo motor 400, the driving wheel 210 and the driven wheel 110 move synchronously, and then the wire feeding roller 100 and the stretching roller 200 move synchronously.

[0031] In this example, the number of winding turns of the wire 99 on the wire feeding roller 100 is 3 turns to prevent slipping between the wire 99 and the wire feeding roller 100. Similarly, the number of winding turns of the wire 99 on the stretching roller 200 is 3 turns to prevent slipping between the wire 99 and the stretching roller 200. Specifically, when the servo motor 400 drives the wire feeding roller 100 and the stretching roller 200 to rotate at the same speed, since the circumference of the stretching roller 200 is 0.5% larger than that of the wire feeding roller 100, the wire 99 between the wire feeding roller 100 and the stretching roller 200 is always stably stretched by 0.5%. Since the wire 99 passes over the induction component 300, there is a positive pressure on the induction component 300. When the annealing degree of the wire 99 is sufficient, the pressure on the induction component 300 is relatively small; when the annealing degree of the wire 99 is insufficient, due to the poor ductility and large tensile stress of the wire 99, the pressure of the wire 99 on the induction component 300 becomes larger.

[0032] Embodiment 2

[0033] Refer to Figure 3 As shown, the present invention also proposes a method for monitoring the annealing degree of a metal wire, including the following steps:

[0034] Stretch the wire through the aforementioned device and obtain the pressure value of the wire passing through the induction component;

[0035] Record the pressure value and transmit it to the computer;

[0036] The computer processes the pressure value and forms a stress measurement curve of the wire.

[0037] It also includes that when the pressure value is higher than or lower than a preset pressure range, an alarm prompt is output. For example, the alarm prompt includes an audible and visual alarm, and the alarm prompt is recorded in the computer.

[0038] The computer described in the present invention includes a storage medium for storing the pressure value.

[0039] Specifically, after the pressure value is obtained, it is converted into an electrical signal, amplified and adjusted by a signal processor to become a digital signal, and then transmitted to an industrial computer through an Ethernet port. The industrial computer has a storage medium and can record the stress value in real time to form an intuitive stress measurement curve. The upper and lower limit alarm values of the stress can be set on the industrial computer. When the stress exceeds or is lower than the set value, an alarm prompt will be output, and the industrial computer will also record the time when the alarm occurs. The number of curves and the alarm records can be checked at any time, and the data is permanently stored in the industrial computer and is valid.
