Description

Technical Field

[0001] This invention relates to the field of diamond wire production and testing (IPC classification number G01N15 / 02), and more particularly to a diamond wire production and testing system for magnetic materials. Background Technology

[0002] Magnetic materials, also known as magnetic materials, have the function of converting, transmitting, processing, and storing information and energy. They play an irreplaceable role in industries such as medicine, energy, information, and automation. However, magnetic materials inevitably need to be cut during processing and use. For magnetic materials with different conductivity, traditional electrical discharge cutting cannot meet the requirements. Therefore, diamond wire cutting is mainly used for cutting magnetic materials. By attaching diamond powder to a steel wire, under high-speed cutting, the diamond powder drives the steel wire to roll and embed into the interior of the magnetic material. Therefore, the cutting effect of magnetic materials is closely related to the distribution of diamond powder on the diamond wire.

[0003] In the production of diamond wire, it is necessary to monitor the surface coating of the steel wire in real time. By adjusting the steel wire and diamond grit in the grit-applying tank, the amount of grit on the steel wire is kept stable. Based on the monitoring data, adjustments are made to indicators that are out of control to improve product stability. Existing diamond wire production monitoring systems have the following problems: 1. The monitoring position is located before the take-up chamber, and the diamond grit surface is already covered with a nickel layer, making it difficult to judge the coating condition during the grit-applying process; 2. Changes in the amount of grit after adjusting the grit-applying tank require passing through a thickened wire mesh before being transmitted to the camera monitoring system, resulting in long debugging times and significant material waste; 3. Low monitoring accuracy leads to excessive diamond grit agglomeration and large fluctuations in grit amount, making it easy for magnetic materials to produce wire marks during diamond wire cutting.

[0004] Existing technology CN111364087A discloses a diamond wire magnetic levitation dual-wire control sanding system, which uses a sanding cylinder and a rotating magnetic ring to electroplate diamond sand and nickel ions onto steel wire in one go. However, the sanding situation cannot be clearly observed after electroplating, making precise adjustment difficult and easily leading to unstable diamond wire cutting rate and wire marks during cutting. Existing technology CN207396376U discloses a diamond wire sanding detection device, which uses a rotating cylinder and an air jet pipe to simultaneously detect and dry two diamond wires. However, it cannot be used for multi-wire machine production, and the detection device can only alarm and cannot adjust in time.

[0005] To address the aforementioned issues, this invention provides a production and testing system for diamond wire used in magnetic materials. By optimizing the device structure and operating parameters, it improves the uniformity of abrasive grinding on diamond wire while reducing material waste during rapid debugging. This system can be used for production and testing on multi-wire machines. Summary of the Invention

[0006] To address the aforementioned problems, this invention provides a production and testing system for diamond wire used in magnetic materials, comprising a stabilizing guide device, a testing device, an operating device, and a correction device.

[0007] Preferably, the stabilizing guide device includes a guide wheel and a mounting plate.

[0013] Preferably, the camera is connected to a slider that moves left and right via a horizontally placed slide rail.

[0014] The applicant discovered that by setting up sliders and slide rails, the camera can move flexibly on each diamond wire of the multi-thread machine, realizing diamond wire production inspection of the multi-thread machine and greatly improving inspection efficiency.

[0015] Preferably, the stabilizing guide device and the detection device are installed between the sanding process and the thickening process of the diamond wire production line.

[0016] The applicant discovered that by limiting the installation positions of the stabilizing guide device and the detection device, the diamond wire can be adjusted for sanding before electroplating, reducing material waste.

[0018] Preferably, the automatic operating table includes a moving detection device, a moving camera adjustment and correction device.

[0020] The applicant discovered that by setting up a monitor and control panel, staff can accurately monitor the sand content on the diamond wire, improve adjustment precision, and make the product's cutting rate more stable.

[0021] Preferably, the correction device includes a permanent magnet, a slider, and a slide rail.

[0022] Preferably, the permanent magnet is connected to the slider and moves up and down via a longitudinally placed slide rail.

[0023] The applicant discovered that by flexibly adjusting the height of the permanent magnet using sliders and rails, this system can be used for the production and testing of diamond wire of different specifications without the need for multiple production and testing devices.

[0024] Working principle: The steel wire becomes magnetic under the magnetic field of the permanent magnet above. When it passes through the sanding trough, it attracts diamond grit to the surface of the steel wire. The stabilizing guide device keeps the steel wire horizontal. The detection device slider moves according to the preset program of the automatic operating table. The camera transmits the sanding status of the steel wire to the display in the operating device for observation. The slider in the correction device is adjusted to adjust the height of the permanent magnet from the steel wire, thereby adjusting the magnetism of the steel wire to the preset value, and then adjusting the sanding status of the steel wire. The above process is repeated to fine-tune the height of the permanent magnet from the steel wire until the sanding is uniform, does not clump, and the sanding thickness meets the requirements.

[0025] Beneficial effects 1. By using sliders and slide rails, the camera can move flexibly on each diamond wire of the multi-thread machine, enabling diamond wire production inspection and greatly improving inspection efficiency.

[0026] 2. By limiting the installation positions of the stabilizing guide device and the detection device, the diamond wire can be adjusted for sanding before electroplating, reducing material waste.

[0027] 3. By setting up a monitor and control panel, the abrasive condition on the diamond wire can be accurately monitored, improving adjustment precision and making the product's cutting rate more stable.

[0028] 4. By flexibly adjusting the height of the permanent magnet using sliders and slide rails, this system can be used for the production and testing of diamond wire of different specifications without the need for multiple production and testing devices. Attached Figure Description

[0046] Diamond wire was produced on a six-wire machine using 120μm steel wire as the main conductor and diamond abrasive with a D50 value of 25μm. The production line speed was controlled at 12m / min, and the coating thickness was 11μm. The above parameters were input into the automatic operating table, and the slider of the detection device was moved according to the preset program. The camera was adjusted to transmit the abrasive application status of the steel wire to the display in the operating device for observation. The slider in the correction device was adjusted to adjust the height of the permanent magnet from the steel wire. The magnetic field strength of the steel wire was measured to be 3.5Gs by a GM500 gaussmeter. The abrasive application status was observed again. The above process was repeated, and the height of the permanent magnet from the steel wire was continuously fine-tuned until all six diamond wires passing through the camera within 1 minute were uniformly coated with abrasive and did not clump together. The final average outer diameter of the diamond wire was 171μm.
