Description

Technical Field

[0001] The utility model relates to a calcium wire breakage detection device, belonging to the field of metallurgical processing detection equipment. Background Art

[0002] Cored wire is a crucial auxiliary metallurgical material in the steelmaking process, primarily used in refining. It primarily serves to fine-tune the composition of molten steel, alloy it, deoxidize it, and remove inclusions. Pure calcium-coated wire, with its inner calcium wire, desulfurizes the molten steel and modifies the morphology of inclusions, improving its castability and mechanical properties while reducing steelmaking costs. Double-layer pure calcium-coated wire, which penetrates deep into the molten steel, offers advantages such as preventing splashing and increasing calcium recovery, making it widely used in major steel mills nationwide.

[0003] After the production of calcium wire is completed, it is necessary to conduct a wire breakage test. Currently, the wire breakage test is generally a tensile test, which mainly tests the tensile limit that the calcium wire can withstand after being subjected to tension at both ends. However, the applicant took into account that when the calcium wire is subjected to tension, it is not completely balanced tension applied at both ends, and the wire is subjected to pressure in different directions. Therefore, a new detection structure was designed to detect the strength that the calcium wire can withstand when subjected to tension in other directions. Utility Model Content

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0024] Furthermore, the terms "first," "second," "third," etc. are used for descriptive purposes only and are not to be understood as indicating or implying relative importance.

[0025] At the same time, in the description of this utility model, unless otherwise specified or limited, the terms "connected" and "connection" should be understood in a broad sense. For example, it can mean fixed connection, detachable connection, or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to the specific circumstances.

[0026] See Figure 1-4 This is an embodiment of the calcium wire broken wire detection device of the utility model.

[0027] It includes a calcium wire clamp 1 and a pressurizing device 2; the calcium wire clamp 1 includes a mounting bar 3, on which mounting plates 4 are symmetrically arranged, and hinge plates 5 are arranged at the front and rear ends of the mounting plates 4, a rotating shaft 6 is arranged between the hinge plates 5, and a rotating sleeve 7 is fixed on the rotating shaft 6.

[0028] The pressurizing device 2 used in this device is an existing technology and is a universal device for pressure detection. The pressurizing device 2 includes a mounting seat, a mounting shell is provided at the upper end of the mounting seat, a linear motor is provided in the mounting shell, a lifting plate is provided on the linear motor, a pressurizing head is provided at the lower end of the lifting plate, and a pressure sensor is provided on the pressurizing head. During specific use, the staff can operate the pressurizing device 2 through a computer to complete the downward pressure of the pressurizing head. When the pressurizing head is pressed on the pressed object, the pressure sensor on the pressurizing head will detect the magnitude of the pressure. It is a universal device for technicians in this field.

[0029] When using this device, the calcium wire to be tested needs to be straightened and placed horizontally on the upper ends of the two rotating sleeves 7. At this time, the pressure device 2 is operated to align with the middle of the two rotating sleeves 7, and then pressed down, and the pressure head will press on the calcium wire; when the pressure head contacts the calcium wire, the straightened calcium wire will provide an upward resistance to the pressure head, and the pressure sensor will detect the pressure value at this time. The pressure head continues to press down, the more the calcium wire is bent, the greater the resistance provided, and the greater the detected pressure value, until the calcium wire breaks, the pressure value will drop instantly, and a pressure value curve detected by the pressure sensor will appear on the computer. The highest point of the curve is the maximum load that the broken calcium wire can withstand; broken wire detection by external pressure can be achieved.

[0030] In this device, when the calcium wire is deformed under pressure, the entire calcium wire will be stretched. At this time, the rotating sleeve 7 will provide the calcium wire with convenient rotation, and the calcium wire will not be affected by the friction from the rotating sleeve 7 when it is stretched. The reason for this arrangement is that when the calcium wire is subjected to pressure from the pressure-applying head, the pressure will be transmitted to the rotating sleeve 7. If there is sliding friction between the calcium wire and the rotating sleeve 7, then under strong pressure, it will cause the non-detection part of the calcium wire to heat up, affecting the result of the calcium wire breakage detection. The setting of the rotating sleeve 7 can convert sliding friction into rolling friction, and will not cause the calcium wire to generate additional friction.

[0031] A vertical plate 8 is fixed to the upper end of the mounting plate 4 , and the hinged plate 5 is fixed to the front and rear ends of the vertical plate 8 .

[0032] Due to the setting of the mounting strip 3, the deformation space of the calcium wire in this device is small. The vertical plate 8 is used to raise the height of the rotating sleeve 7 in order to provide space for the deformation of the calcium wire. The function of the hinged plate 5 is to install the rotating shaft 6.

[0033] In order to improve the applicability and range of detection, the distance between the rotating sleeves 7 used to bear the pressure of the calcium wire is set to be adjustable, so that the bearing capacity of calcium wires of different lengths can be detected;

[0034] Specifically, a sliding structure 9 is provided between the mounting bar 3 and the mounting plate 4 . The sliding structure 9 includes a slide groove 10 provided in the mounting bar 3 . A slider 11 is provided in the slide groove 10 . The mounting plate 4 is fixed to the upper end of the slider 11 .

[0035] At this time, due to the arrangement of the slide groove 10 and the slider 11 , the mounting plate 4 can slide relative to the mounting bar 3 , and the mounting plate 4 can drive the rotating sleeve 7 to move laterally to adjust the distance between the two rotating sleeves 7 .

[0036] At the same time, in order to facilitate the adjustment of the distance between the two rotating sleeves 7, the device is also provided with a driving device 12 for driving the slider 11 to move; the driving device 12 includes a double-threaded screw 13, the double-threaded screw 13 is placed in the slide groove 10, and both ends are rotatably set on the mounting bar 3, and the double-threaded screw 13 passes through the slider 11 and is threadedly connected to the slider 11, one end of the double-threaded screw 13 is connected to the motor 14 through a coupling, and the double-threaded screw 13 is divided by the middle and has threads with opposite thread directions at both ends.

[0037] With such an arrangement, when the motor 14 is working, it can drive the double-threaded screw 13 to rotate, and the double-threaded screw 13 will drive the slider 11 to move in the slide 10; at the same time, since the double-threaded screw 13 is divided by the middle and has threads with opposite thread directions at both ends, when the double-threaded screw 13 rotates, the two sliders 11 will move laterally relative to each other, so that the adjustment distance is more controllable.

[0038] When the device is used, the calcium wire needs to be straightened, so the end of the calcium wire to be tested needs to be clamped, which can be achieved with the help of existing equipment. At the same time, in order to facilitate operation, the device is provided with a calcium wire clamping device 15 on the mounting plate 4;

[0039] The calcium wire clamping device 15 can realize the clamping operation of the two ends of the calcium wire to be tested without the help of external equipment, which is very convenient.

[0040] The calcium wire clamping device 15 includes a mounting column 16 fixed on the mounting plate 4. A threaded sleeve 17 is provided on the upper end of the mounting column 16. A through hole 18 is provided on the lower part of the threaded sleeve 17 and passes through the inside and outside of the threaded sleeve 17. A clamping bolt 19 is threadedly connected to the threaded sleeve 17.

[0041] The calcium wire clamping device 15 of the present device is used as follows: the end of the calcium wire is placed into the threaded sleeve 17 through the through hole 18, and then the clamping bolt 19 is rotated. The clamping bolt 19 descends and presses on the calcium wire to complete the fixation of the end of the calcium wire. Then, the calcium wire is tightened by the driving device 12.

[0042] A guide ring 20 is provided on the upper end of the mounting column 16 outside the threaded sleeve 17. An opening 21 is provided at one end of the guide ring 20, and the direction of the opening 21 is consistent with the direction of the through hole 18. A rotating ring 22 is fixed to the upper end of the tightening bolt 19, and a rotating rod 23 is fixed inside the rotating ring 22.

[0043] The guide ring 20 of this device is mainly used to guide the direction of the calcium wire, to facilitate the horizontal and vertical positioning of the calcium wire, and to facilitate subsequent wire breakage detection; the rotating ring 22 and rotating rod 23 of this device are used to facilitate the staff to rotate the tightening bolt 19 in the future.

[0044] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
