Description

Technical Field

[0001] This utility model relates to the field of in-situ stretching of alloy materials, and more specifically, to an in-situ stretching device for preparing copper alloy materials. Background Technology

[0002] Traditional tensile testing of copper alloys is typically conducted on a macroscopic scale, making it impossible to directly observe the microstructural changes during the tensile process. This hinders researchers' understanding of the deformation and failure mechanisms of copper alloys. For example, in traditional tensile tests, only macroscopic parameters such as fracture strength are obtained when the material fractures, without revealing how the fracture begins and develops at the microscopic level. To overcome the limitations of traditional tensile testing, in-situ tensile testing technology has emerged. In-situ tensile testing allows real-time observation of microstructural changes during the tensile process, such as grain deformation, dislocation movement, and second-phase precipitation. This is crucial for in-depth research into the relationship between the mechanical properties and microstructure of copper alloys. For instance, in-situ tensile testing can observe grain boundary slip and dislocation accumulation during tensile testing, thereby revealing the deformation and strengthening mechanisms of the material.

[0003] Although there are some in-situ tensioning devices, these devices still have some shortcomings in use. The alloy materials are diverse, and for materials of different shapes, such as rods, plates, and tubes, the existing devices are difficult to adapt and fix according to the different shapes of the materials.

[0004] Therefore, it is necessary to redesign an in-situ stretching device for preparing copper alloy materials to address the above-mentioned problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1-4 An in-situ stretching device for preparing copper alloy materials includes a mounting base 1. The upper end of the mounting base 1 is symmetrically provided with multiple sliding grooves 8. A driving device is provided between two corresponding sliding grooves 8. A fixing plate 4 is fixedly connected to the output end of each driving device. A moving groove 13 is provided on one side of each fixing plate 4. An adjustment device is provided in each moving groove 13. Two first clamping blocks 11 are fixedly installed on the output end of each adjustment device. A slot 12 is provided on each first clamping block 11. A clamping device is provided in each slot 12.

[0025] like Figure 1-4 As shown, the specific implementation method is as follows: by setting up a driving device, a fixed plate 4, an adjusting device, a motor 3 and other devices, the motor 3 can drive the driving device to stretch the material fixed on the fixed plate 4 in situ. By setting up a fixed plate 4, an adjusting device, a first clamping block 11, a clamping device and other devices, the adjusting device can drive the first clamping block 11 to clamp the cylindrical material according to the size of the material. The clamping device can simultaneously adjust the device to clamp the rectangular material, thus achieving the purpose of clamping and fixing materials of different shapes.

[0026] Each drive unit includes two reciprocating lead screws 9, which are respectively mounted on the inner sidewalls of corresponding slide grooves 8 via bearings. Each reciprocating lead screw 9 is threadedly connected to a slider 10, and the two sliders 10 are respectively slidably locked in the corresponding slide grooves 8. The fixing plate 4 is fixedly installed on the upper end face of the two sliders 10. One end of each of the two reciprocating lead screws 9 passes through the inner sidewalls of the corresponding slide grooves 8 and extends outward together to be equipped with a synchronization component. The synchronization component can drive the two reciprocating lead screws 9 to rotate in the slide grooves 8. The rotation of the reciprocating lead screws 9 can drive the two sliders 10 to move synchronously in the slide grooves 8, and thus the fixing plate 4 can be moved by the sliders 10.

[0027] Each synchronization component includes a first synchronization pulley 5 and a second synchronization pulley 6, and the first synchronization pulley 5 and the second synchronization pulley 6 are respectively fixedly installed at one end of the reciprocating lead screw 9 in corresponding positions. A synchronization belt 7 is installed between the first synchronization pulley 5 and the second synchronization pulley 6, and the first synchronization pulley 5 can drive the second synchronization pulley 6 to move synchronously through the synchronization belt 7.

[0028] The adjusting device includes a double-threaded rod 14, which is mounted on the inner wall of the moving groove 13 via bearings. The double-threaded rod 14 is threadedly connected to two moving blocks 15, which are slidably locked in the moving groove 13. Two first clamping blocks 11 are fixedly connected to one side of the two moving blocks 15 respectively. One end of the double-threaded rod 14 passes through the inner wall of the moving groove 13 and extends outward to be fitted with a first handle 18. It should be noted that the two moving blocks 15 are threadedly connected to two opposite threads on the double-threaded rod 14.

[0029] Each clamping device includes a screw 17, which is threadedly connected to one side of the first clamping block 11 at the corresponding position. One end of the screw 17 passes through one side of the first clamping block 11 and extends into the slot 12. A second clamping block 16 is mounted on one end of the screw 17 via a bearing. A second handle 19 is fixedly mounted on the end of the screw 17 away from the second clamping block 16. Rotation of the screw 17 can drive the second clamping block 16 to move out of the slot 12.

[0030] Mounting brackets 2 are fixedly installed on both sides of the mounting base 1. Each mounting bracket 2 is fixedly installed with a motor 3, and the output shafts of the two motors 3 are respectively fixedly connected to one side of the first synchronous pulley 5 corresponding to the position. The motors 3 can drive the first synchronous pulley 5 to rotate.

[0031] In use, the copper alloy material to be stretched is first placed between the two first clamping blocks 11. Then, the screw 17 is rotated according to the shape of the material. The screw 17 can drive the second clamping block 16 to move within the slot 12. If it is a cylindrical material, the second clamping block 16 can be moved into the slot 12. Then, the second handle 19 is rotated, which can drive the double-ended threaded rod 14 to rotate. The double-ended threaded rod 14 can drive the two moving blocks 15 to move relative to each other. Then, the moving blocks 15 can drive the two first clamping blocks 11 to move closer to each other until the two first clamping blocks 11 move closer together. Clamping block 11 clamps cylindrical material. If it is rectangular material, screw 17 can be rotated, causing screw 17 to drive second clamping block 16 to move out of slot 12. Then, second handle 19 can be rotated, which can drive double-ended threaded rod 14 to rotate. Double-ended threaded rod 14 can drive two moving blocks 15 to move relative to each other. Then, moving blocks 15 can drive two first clamping blocks 11 to move closer to each other. At this time, two first clamping blocks 11 can drive second clamping block 16 to move synchronously. Since second clamping block 16 moves out of slot 12, second clamping block 16 will clamp rectangular material.

[0032] After the material is clamped, two motors 3 can be started simultaneously. The output shaft of the motor 3 can drive the first synchronous wheel 5 to rotate. The first synchronous wheel 5 can drive the second synchronous wheel 6 to rotate synchronously through the synchronous belt 7. Then, the first synchronous wheel 5 and the second synchronous wheel 6 can simultaneously drive the two reciprocating screws 9 to rotate. At this time, the reciprocating screws 9 can drive the slider 10 to move in the slide groove 8. The movement of the slider 10 will drive the fixed plate 4 to move synchronously. Then, the fixed plate 4 can drive the material clamped on it to be stretched in situ.
