DETAILED DESCRIPTION

[0028] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0029] Example 1

[0030] Combination Figures 1-9 As shown, a metal coating repeated bending test device with replaceable support heads includes a machine tool 1, on which a bending assembly is installed. A sliding groove is opened on one side of the bending assembly on the machine tool 1. The bending assembly is used to repeatedly bend the metal coating product under test. Two moving stages 11 are symmetrically slidably arranged in the sliding groove. Two support heads 18 are detachably installed on the opposite sides of the two moving stages 11. The top of the support head 18 has an arc-shaped curved part, which is a support angle. The radius of the support angle of the support head 18 is half the thickness of the bent sample.

[0031] The bending assembly includes a bearing 2, a swing arm 3, a handle 4, and a swing clamp 6. The bearing 2 is mounted on the machine tool 1. The bottom of the swing arm 3 is rotatably mounted on the bearing 2. The handle 4 is rotatably mounted on the upper part of the swing arm 3. The swing clamp 6 is mounted on the swing arm 3. The swing clamp 6 has an opening in the middle for the metal-plated product to pass upward. The swing clamp 6 is located above the support head 18. A strip-shaped notch is opened between the two support heads 18 on the machine tool 1 for the metal-plated product to pass downward.

[0032] In this embodiment, two support heads 18 are installed on two moving stages 11. Then, the metal coating product to be tested is inserted between the two support heads 18. Then, the two moving stages 11 drive the two support heads 18 to move closer to each other and clamp the metal coating product. The upper end of the metal coating product is inserted into the opening of the swing clamp 6. Then, by holding the handle 4, the swing rod 3 can be swung through the handle 4. The rotation of the swing rod 3 drives the swing clamp 6 to swing. In turn, the swing clamp 6 repeatedly bends the metal coating product inserted into its opening to conduct the experiment.

[0033] Among the test requirements, the support head 18 corner radius needs to be half the thickness of the bent sample. Therefore, for products with metal coatings of different thicknesses, support heads 18 with different corner radii can be used.

[0034] Both moving platforms 11 have insert posts 12 on their opposite sides, and both support heads 18 have insertion holes that match the insert posts 12.

[0035] Different sized support heads 18 can be quickly disassembled and replaced via the inserts 12 on the moving platform 11.

[0036] The swing rod 3 has a groove, and a sliding seat 5 is slidably disposed in the groove of the swing rod 3. A fastening bolt 7 is threadedly connected to the sliding seat 5, and the swing clamp 6 is fixedly connected to the sliding seat 5.

[0037] For test products of different lengths, the height of the sliding seat 5 and the swing clamp 6 can be adjusted up and down. After adjusting to different heights, they can be fixed by fastening bolts 7.

[0038] Furthermore, the swing clamp 6 and the sliding seat 5 are detachably connected. Different thicknesses of metal-plated products require swing clamps 6 with different opening widths. Different swing clamps 6 can be disassembled and replaced according to the different thicknesses of the products to be tested.

[0039] The opening gap of the swing clamp 6 needs to be slightly larger than that of the metal coating product to be tested.

[0040] This allows the testing device to be quickly disassembled and the support head replaced according to the different thicknesses and testing requirements of the substrate material of different metal coating products, greatly improving the adaptability of the testing device and making it suitable for metal coating products of various sizes.

[0041] Different specifications of repeated bending test support heads are designed according to different thicknesses of the base material. When the support head is replaced during the test, other assembly parts of the same repeated bending test machine remain unchanged, and only the support head needs to be replaced.

[0042] The device has a compact structure, does not occupy additional space, and is easy to move and deploy in laboratories or production sites. It greatly improves work efficiency and is easy to operate.

[0043] Example 2

[0044] Combination Figures 1-9 As shown, the difference between this embodiment and Embodiment 1 is that:

[0045] It also includes a spacing control component, which includes a power motor 8, a lead screw 9 and a connecting rod 10. The power motor 8 is mounted on the machine tool 1, and both ends of the lead screw 9 are mounted on the machine tool 1 through bearing seats. One end of the lead screw 9 is fixed to the output shaft of the power motor 8.

[0046] There are two connecting rods 10, each of which is fixed to a movable table 11. The threads on both sides of the outer surface of the lead screw 9 are in opposite directions, and the two connecting rods 10 are threaded to both sides of the outer surface of the lead screw 9 respectively.

[0047] In this embodiment, the power motor 8 drives the lead screw 9 to rotate. The rotation of the lead screw 9 can cause the two connecting rods 10 to move closer or further away from each other. In turn, the two connecting rods 10 can cause the two moving stages 11 to move further or closer to each other, so that the two moving stages 11 can cause the two support heads 18 to move closer or further away from each other, thereby clamping or releasing the product being tested.

[0048] Example 3

[0049] Combination Figures 1-9 As shown, the difference between this embodiment and Embodiment 2 is that:

[0050] Each support head 18 has a slotted groove on the upper part of both sides and includes a replacement component. The replacement component includes a mounting bracket 13, a telescopic drive component 14, a crossbeam 15, a slider 16, a positioning clamp 17, and an elastic element 19. There are two mounting brackets 13, which are fixed to the machine tool 1. There are two telescopic drive components 14, which are respectively mounted on the two mounting brackets 13. The crossbeam 15 is mounted on the telescopic ends of the two telescopic drive components 14. Two sliders 16 are slidably mounted on the crossbeam 15. A positioning clamp 17 is fixed to each slider 16. Each positioning clamp 17 is inserted into the slotted groove on both sides of one support head 18. Two elastic elements 19 are symmetrically mounted on the crossbeam 15. The other ends of the two elastic elements 19 are respectively connected to the two sliders 16.

[0051] In this embodiment, when the support head 18 needs to be installed, the telescopic drive member 14 is in a retracted state, and the two support heads 18 are respectively inserted into the two positioning clamps 17. Then, the telescopic drive member 14 extends, driving the support head 18 to move to the position between the two moving platforms 11. Then, the product to be tested is inserted and placed between the two support heads 18. At this time, the two moving platforms 11 begin to move closer, thereby driving the insertion post 12 to be inserted into the insertion hole on the support head 18, further driving the two support heads 18 to move closer to each other, clamping the product to be tested. At this time, the elastic member 19 is stretched, and then the product to be tested is bent. After the bending is completed, the moving platforms 11 move away from each other, and the elastic member 19 returns to its original position. The two support heads 18 are moved away from each other. Due to the elastic force of the elastic element 19, the support heads 18 are stopped by the elastic element 19, while the moving stage 11 continues to move away from each other. As a result, the insertion post 12 of the moving stage 11 can be pulled out from the insertion hole of the support head 18. This realizes the automatic separation of the moving stage 11 and the support head 18 before and after the test. When replacing the product next time, the support head 18 can be directly removed from the positioning clamp 17 for replacement, which saves the process of repeated manual disassembly and assembly. There is no need for manual insertion of the support head 18 into the insertion post 12 of the moving stage 11. This avoids manual disassembly and installation operations in the narrow space between the two moving stages 11, and improves the overall efficiency of the test.

[0052] Two pins 12 are fixed to each moving platform 11, and the support head 18 has two insertion holes. The two pins 12 make the installation more stable.

They are only used to illustrate the technical ideas and features of the present utility model, with the aim of enabling those skilled in the art to understand the content of the present utility model and implement it accordingly. However, they are not limited to the present utility model, and the patent scope of the present utility model cannot be limited by this embodiment alone. That is, any equivalent changes or modifications made to the spirit disclosed in the present utility model, without departing from the structure of the present utility model, such as local improvements within the system and modifications or transformations between subsystems, are still within the patent scope of the present utility model.
