DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0024] Please refer to Figure 1-4 ;

[0025] The material folding test fixture described in the present invention is used less frequently and is basically only needed when a new product is developed. In addition, the testing process is relatively fast, so it is more convenient to use manual operation. Of course, it is not excluded that the technology in this embodiment is used as a tool for mass production. Further explanation: PIN pins are usually used in combination in multiples, and they are connected with the material belt in the process of making PINs, so multiple PIN pins are used together for material folding testing. At the same time, the relative positions of multiple PIN pins are fixed by the material belt, which can ensure that the positions of multiple PIN pins are the same and ensure the rigor of the test. Specifically, it includes a base 1, and a fixing seat 1 2 and a fixing seat 2 3 are relatively arranged on the base 1; a material fixing part 4 is arranged on the upper end surface of the fixing seat 1 2, and a material folding fixing assembly 5 is arranged opposite to the material fixing part 4, and the material folding fixing assembly 5 is slidably connected to the side of the fixing seat 1 2, and a manual lifting assembly 6 is arranged on the fixing seat 2 3, and the manual lifting assembly 6 is connected to the material folding fixing assembly 5;

[0026] When in use, put the material to be tested into the material fixing part 4, and put the position where the material needs to be folded into the material folding fixing component 5, and fix these two parts by the material fixing part 4 and the material folding fixing component 5 respectively, and then apply external force to the manual lifting component 6 to drive the material folding fixing component 5 to move up and down. Since the material fixing part 4 fixes the material and the position of the material is fixed, only the material folding fixing component 5 drives the folding part to move up and down relative to the material to realize the process of continuous bending. The manual lifting component 6 drives the material folding fixing component 5 to move up and down for two bends. At this time, the bending test can be recorded by counting. When the folding part is disconnected from the material, the operation is stopped. The recorded number of times is the final number of metal fatigue tests. This process can be checked by the naked eye.

[0027] The utility model adopts manual operation throughout the whole process, does not need the assistance of a power device, and does not need to be connected to a power source or a starting component. It has a simple structure, low production cost, and is very convenient to use.

[0028] The utility model can have multiple implementation modes for the folding material fixing component 5; for example, it includes a folding material fixing part 51, which is slidably connected to the fixing seat 2, and a swing arm is rotatably connected to the lower part of the folding material fixing part 51. In this embodiment, the manual lifting component 6 includes a rotating shaft 61 that passes through the fixing seat 23, one end of the rotating shaft 61 is connected to a hand-cranked turntable 62, and the other end of the rotating shaft 61 is provided with a connecting head 63, and the end face of the connecting head 63 is provided with a transmission part 64 that is non-coaxially arranged with the rotating shaft 61, and the transmission part 64 is connected to the folding material fixing component 5; when the user manually rotates the hand-cranked turntable 62, the rotating shaft 61 will also rotate accordingly, and at this time the transmission part 64 will move in a circle with the rotating shaft 61 as the center, and the swing arm will realize up and down movement driven by the transmission part 64, thereby pushing the folding material fixing part 51 to rise and fall; in this embodiment, the manual lifting component 6 can realize the rising and falling of the folding material fixing part 51 by hand-cranking, which is very labor-saving and convenient for the operator to use.

[0029] Furthermore, the present utility model has other embodiments for the folding material fixing assembly 5, specifically including a folding material fixing portion 51, a slide seat 52 is fixedly arranged below the folding material fixing portion 51, the slide seat 52 is slidably connected to the side wall of the fixing seat 2, a strip hole 53 is horizontally arranged on one side of the slide seat 52, and the transmission portion 64 is placed in the strip hole 53. In addition, the manual lifting assembly 6 in this embodiment uses the structure of the above-mentioned hand-cranked turntable 62, the rotating shaft 61, the connecting head 63 and the eccentrically arranged transmission portion 64;

[0030] Preferably, the transmission part 64 is cylindrical, and the width of the bar hole 53 is greater than the diameter of the transmission part 64, so that the transmission part 64 can have a certain space for movement when it moves; when the user manually rotates the hand-cranked turntable 62, the rotating shaft 61 will also rotate accordingly. At this time, the transmission part 64 will move in a circle with the rotating shaft 61 as the center. The transmission part 64 can move in the bar hole 53 and at the same time push the slide 52 to move up and down, that is, the folding material fixing part 51 follows the slide 52 to rise or fall.

[0031] In one embodiment of the material fixing part 4 of the utility model, a fixing block 41 is specifically provided, and the fixing block 41 is rotatably connected with a cover plate 42, and a placement position 43 for placing materials is provided on the fixing block 41; first, the cover plate 42 is rotated to separate it from the end face of the fixing block 41, and the placement position 43 is exposed at this time, and then the material is placed therein, and of course, the part that needs to be tested for bending will extend out of the placement position 43 and enter the folding material fixing part 51, and then the cover plate 42 is rotated to reset, so that the cover plate 42 fits the edge of the fixing part, and forms a folding material clamping position 44, and at the same time, the bottom surface of the cover plate 42 contacts the material. It is equivalent to pressing the material tightly and fixing the edge of the material, and finally, based on the above embodiment, the folding material fixing part 51 is moved up and down, driving the folding part to bend repeatedly until it breaks.

[0032] Since the overall volume of the several PIN needles connected to the material strip is relatively small, such an implementation method can more conveniently realize material loading. In addition, during the test, it is necessary to use the other hand to press the cover plate 42 against the end face of the fixed block 41 to prevent the PIN needles from shaking.

[0033] Preferably, the folding material clamping position 44 is tilted so as to better compress the PIN needle and avoid shaking.

[0034] Preferably, the placement position 43 has the same length direction as the material fixing portion 4, and can adapt to PIN needle combinations of different lengths, that is, can test PIN needle combinations of different lengths.

[0035] In the embodiment of the utility model, the folding material fixing part 51 includes a second fixing block 511 , and a folding material movable position 512 is provided on one side of the second fixing block 511 corresponding to the folding material clamping position 44 , and a gap is provided in the folding material movable position 512 for materials to enter.

[0036] Furthermore, two bending arms 513 are provided opposite to each other and inclined on one side of the fixed block 511, and the two bending arms 513 are combined to form a folding material movable position 512. A hollow position 514 is provided on one side of the fixed block close to the bending arm 513, and the broken folding material part can fall down from the hollow position 514 to avoid accumulation in the folding material movable position 512.

[0037] It can be seen from all the above embodiments that the utility model only adopts a simple combination of parts, the cost is very low, it is very cost-saving for fixtures that are not used frequently, and it is very convenient to operate.

[0038] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
