Description

Technical Field

[0001] This utility model relates to the field of molybdenum wire production technology, and in particular to a tension adjustment device for molybdenum wire production. Background Technology

[0002] Molybdenum wire is an important metallic material, mainly used in electronics, metallurgy, aerospace and medical fields. During the production process of molybdenum wire, it is necessary to adjust the tension of the wire to keep it taut in order to ensure the accuracy of the wire during processing and subsequent processing. Therefore, a molybdenum wire tension adjustment device is required.

[0003] Chinese patent document CN206854789U discloses a wire cutting molybdenum wire tension adjustment device, which consists of a guide rail, a guide wheel, a guide wheel support, an S-shaped pressure sensor, a guide rod, a pressure spring, an adjustable pressure plate, an end cover, an adjusting screw, and a four-position electronic display instrument. Its features include: the guide wheel support and the adjustable pressure plate are installed in the inner V-groove of the guide rail and can move along the inner V-groove; the S-shaped pressure sensor is installed on the left side of the guide wheel support; the end covers are all installed on the left end of the guide rail and fixed with screws; the guide wheel is installed on the guide wheel support; the guide rod is installed on the left end of the S-shaped pressure sensor; the pressure spring is installed on the guide rod and between the adjustable pressure plate and the S-shaped pressure sensor; the adjusting screw is installed in the screw hole of the end cover; and the four-position electronic display instrument is installed on the machine tool. During operation, the tension is achieved by two adjusting screws pushing an adjustable pressure plate, which in turn pushes a pressure spring. The spring then presses against a pressure sensor, which is connected to a guide wheel support seat by a screw. This causes the guide wheel to press against the molybdenum wire. The tension can be controlled by the adjusting screws, and a four-digit electronic display instrument can read the tension at any time. The tension is changed by adjusting the screws and altering the stroke of the pressure plate, resulting in different pressures from the compression of the pressure spring. However, during use, the molybdenum wire transmission may experience asynchrony, leading to changes in the wire tension. Therefore, dynamic adjustment of the molybdenum wire tension is not possible, and improvements are needed. Utility Model Content

[0023] The technical solutions of the present utility model will be explained and described below with reference to the accompanying drawings. However, the following embodiments are only preferred embodiments of the present utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments in the implementation methods without creative effort are all within the protection scope of the present utility model.

[0024] The following describes in detail, with reference to the accompanying drawings, a tension adjustment device for molybdenum wire production according to an embodiment of the present invention.

[0025] Example 1

[0026] For easier understanding, please refer to Figures 1 to 4 An embodiment of a tension adjustment device for molybdenum wire production provided by this utility model includes a base 1, a support frame 2 and a first fixed frame 3. A first tension wheel 4 and a second tension wheel 5 are provided on one side of the first fixed frame 3. A dynamic pressure adjustment component is provided between the base 1 and the first fixed frame 3. A range adjustment component is provided inside the first fixed frame 3. The support frame 2 is fixedly installed on the top of the base 1, and the first fixed frame 3 is rotatably connected to one side of the top of the support frame 2.

[0027] The dynamic pressure adjustment assembly includes a support rod 501, a pressure sensor 502, a fixed base 503, and an electric telescopic rod 504. One end of the support rod 501 is fixedly installed on one end of the rotating shaft of the support frame 2. The pressure sensor 502 is fixedly installed on the top of the base 1. The fixed base 503 is fixedly installed on the top of the pressure sensor 502. The electric telescopic rod 504 is movably installed between the support rod 501 and the fixed base 503. One end of the electric telescopic rod 504 is rotatably connected to one end of the support rod 501, and the other end of the electric telescopic rod 504 is rotatably connected to the inner side of the top of the fixed base 503. The fixed base 503 is fixedly installed on the detection end of the pressure sensor 502.

[0028] It should be noted that by setting a pressure sensor 502, the pressure threshold set by the pressure sensor 502, excluding other external forces, is set between 5-10N. The electric telescopic rod 504 pushes the support rod 501, changing the angle of the first fixed frame 3. The first tension wheel 4 and the second tension wheel 5 support the molybdenum wire, and the tension of the molybdenum wire is adjusted. During the adjustment process, the electric telescopic rod 504 pushes or pulls the support rod 501, so that the pressure received by the pressure sensor 502 is kept constant between 5-10N, thereby dynamically adjusting the tension of the molybdenum wire, which is convenient to use.

[0029] Example 2

[0030] In some embodiments, such as Figure 1 , Figure 3 , Figure 4 As shown, the range adjustment assembly includes two fixed shafts 601, an adjusting screw 602, a second fixed frame 603, and a drive motor 604. The two fixed shafts 601 are slidably connected to the inner side of the first fixed frame 3, the adjusting screw 602 is rotatably connected to the inner side of the first fixed frame 3, the second fixed frame 603 is fixedly installed at one end of the first fixed frame 3, the drive motor 604 is fixedly installed at one end of the second fixed frame 603, the first tension wheel 4 and the second tension wheel 5 are respectively fixedly installed at one end of the two fixed shafts 601, and the adjusting screw 602 is rotatably connected to the middle of the fixed shaft 601, and the adjusting screw 602 is connected to the fixed shaft 601.

[0031] It should be noted that by setting a fixed shaft 601 that can move inside the first fixed frame 3, the adjusting screw 602 is rotated by the drive motor 604 to mesh with the two fixed shafts 601, thereby adjusting the distance between the two fixed shafts 601, and thus adjusting the distance between the first tensioning wheel 4 and the second tensioning wheel 5, thereby further expanding the tension adjustment range of the molybdenum wire to meet the processing requirements.

[0032] Working principle: In use, the drive motor 604 drives the adjusting screw 602 to rotate, making it mesh with the two fixed shafts 601. Adjusting the distance between the two fixed shafts 601 adjusts the distance between the first tensioning wheel 4 and the second tensioning wheel 5, thus adjusting the tension range of the first tensioning wheel 4 and the second tensioning wheel 5 of the tension adjusting device. Then, the electric telescopic rod 504 pushes the support rod 501 to change the angle of the first fixed frame 3. The first tensioning wheel 4 and the second tensioning wheel 5 support the molybdenum wire, and the tension of the molybdenum wire is adjusted. During the adjustment process, the electric telescopic rod 504 pushes or pulls the support rod 501, so that the pressure received by the pressure sensor 502 is kept constant within the set threshold range, thereby dynamically adjusting the tension of the molybdenum wire, which is convenient to use.
