DETAILED DESCRIPTION

[0054] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the embodiment of the present application will be described in more detail below in conjunction with the drawings in the preferred embodiments of the present application. In the drawings, the same or similar reference numerals throughout represent the same or similar parts or parts with the same or similar functions. The described embodiments are part of the embodiments of the present application, not all of the embodiments. The embodiments described below with reference to the drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application. The embodiments of the present application are described in detail below in conjunction with the drawings.

[0055] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0056] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are orientations or positional relationships based on the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present application.

[0057] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0058] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0059] In order to detect the acid resistance, sulfur resistance and corrosion resistance of metal sheets, it is usually necessary to perform resistance testing on the metal sheets. Before the resistance testing, it is necessary to make a test sample, that is, a metal sheet with a length of 40mm, a width of 100mm and a thickness of 0.15-0.4mm is bent into five layers with a width of 20mm. The turning point is a rounded transition with a radius of 1.5mm. In the prior art, a 3mm round bar is usually used as a tool, and the metal sheet is manually press-bent for multiple times to bend the metal sheet into a five-layer laminated test sample.

[0060] However, this bending method is inconvenient to operate and the sample preparation is not standardized. This is because a round bar is used as a bending tool. When bending, the operator places the round bar on the metal sheet and then bends the two sides of the metal sheet in the same direction relative to the round bar. The round bar is easy to move relative to the metal sheet, which is not only inconvenient to operate, but also easy to scratch the surface of the metal sheet. In addition, since bending the metal sheet mainly depends on the experience of the operator, the difference in the test samples formed by each bending is large, and it is difficult to ensure that the fillet radius of the bend and the width of the laminate meet the requirements, resulting in non-standard test samples.

[0061] Based on this, an embodiment of the present application provides a bending sample making device, which is easy to operate and has more standardized sample making.

[0062] The technical solution of the bending sample preparation device provided in the embodiment of the present application is described in detail below in conjunction with the accompanying drawings.

[0063] Figure 1 A schematic diagram of the structure of a bending sample preparation device provided in an embodiment of the present application; Figure 2 for Figure 1 Schematic diagram from another angle; Figure 3 for Figure 1 A top view of Figure 4 for Figure 1 Rear view of the . Figures 1 to 4As shown, the bending sample preparation device provided in the embodiment of the present application is used for bending metal sheets, and includes a frame assembly 100, a slider structure 200 and a bending structure 300. The slider structure 200 and part of the bending structure 300 are located in the frame assembly 100, and the slider structure 200 is connected to the frame assembly 100. The slider structure 200 can move relative to the frame assembly 100 so that the slider structure 200 and the frame assembly 100 can jointly bend the metal sheet.

[0064] The bending structure 300 includes at least two first bending parts 310 and at least two first driving components 320. The first driving components 320 are connected to the frame component 100. The first driving components 320 are connected to the first bending parts 310 one by one. The first driving components 320 are used to drive each first bending part 310 to move toward the slider structure 200 in turn, so that the first bending parts 310 and the slider structure 200 can jointly bend the metal sheet again.

[0065] In the present application, the frame assembly 100 is used to fix the slider structure 200 and the bending mechanism. When performing a bending operation, the slider structure 200 is moved relative to the frame assembly 100 so that the slider structure 200 and the frame assembly 100 jointly bend the metal sheet, thereby forming a straight metal sheet into a V-shaped metal sheet. Afterwards, the first driving assembly 320 drives the first bending member 310 to move relative to the frame assembly 100 toward the slider structure 200, thereby allowing the first bending member 310 and the slider structure 200 to jointly bend the metal sheet again.

[0066] For example, the bending structure 300 may include two first bending parts 310 and two first driving components 320. The first driving components 320 are connected to the first bending parts 310 in a one-to-one manner. One first driving component 320 first drives the corresponding first bending part 310 to move toward the slider structure 200 so that the V-shaped metal sheet forms a W-shaped metal sheet. Then, the other first driving component 320 drives the corresponding first bending part 310 to move toward the slider structure 200 so that the W-shaped metal sheet forms a five-layer stacked metal sheet, thereby producing a metal sheet inspection sample. Therefore, through the cooperation of the frame assembly 100, the slider structure 200, the first bending member 310 and the first driving assembly 320, a flat metal sheet can be bent into a five-layer stacked metal sheet test sample. Compared with the prior art, it is not only more convenient and quicker to operate, but also the metal sheet is not easy to slide relative to the bending sample making device during bending, thereby avoiding scratching the surface of the metal sheet. In addition, the difference between the metal sheet test samples produced each time is small, and the sample making of the metal sheet test samples is more standardized.

[0067] Alternatively, the bending mechanism may include three first bending parts 310 and three first driving components 320, and the first driving components 320 are connected to the first bending parts 310 one by one, and the first driving components 320 sequentially drive each first bending part 310 to move toward the slider structure 200, so that the first bending parts 310 and the slider structure 200 jointly bend the metal sheet again, thereby bending a flat metal sheet into a six-layer laminated metal sheet test sample.

[0068] The bending sample preparation device provided in the embodiment of the present application is provided with a frame assembly 100 for fixing a slider structure 200 and a bending mechanism, and with a slider structure 200 and a bending structure 300 for bending a metal sheet. The slider structure 200 is moved relative to the frame assembly 100 so that the slider structure 200 and the frame assembly 100 together bend the metal sheet once, thereby forming a V-shaped metal sheet from a straight metal sheet. The bending structure 300 is provided with a first driving assembly 320 for driving the first bending member 310 so that each first bending member 310 and the slider structure 200 together bend the metal sheet again in sequence, thereby forming a metal sheet test sample with at least five layers of laminated layers. Therefore, the bending sample preparation device is more convenient to operate and the sample preparation is more standardized.

[0069] Figure 5 for Figure 1 A schematic diagram of the structure of the mid-frame assembly; Figure 6 for Figure 1 The schematic diagram of the middle slider structure. Figure 5 and Figure 6 As shown, in a specific implementation, the frame assembly 100 includes a frame body 110 and a second bending piece 120, the slider structure 200 includes a slider 210 and a third bending piece 220, the frame body 110 has an entrance 111 on its side wall, the second bending piece 120 and the slider 210 are both located in the frame body 110, and the second bending piece 120 and the slider 210 are both connected to the frame, and the extension direction of the second bending piece 120 and the extension direction of the third bending piece 220 are both consistent with the extension direction of the first bending piece 310.

[0070] The slider 210 is connected to the third bending member 220 , and the slider 210 and the third bending member 220 move together toward the second bending member 120 , so that the second bending member 120 and the third bending member 220 bend the metal sheet together.

[0071] In this way, the metal sheet can be put into the frame body 110 through the entrance 111 on the frame body 110 and placed between the frame body 110 and the slider 210, and then the slider 210 and the third bending member 220 are moved relative to the frame body 110 toward the second bending member 120, so that the second bending member 120 and the third bending member 220 jointly bend the metal sheet once, thereby bending the straight metal sheet into a V-shaped metal sheet.

[0072] Reference Figure 3 and Figure 4 As shown, in a possible implementation, the slider structure 200 further includes a second driving assembly 230 , which is connected to the slider 210 , so that the second driving assembly 230 drives the third bending member 220 to move toward the second bending member 120 through the slider 210 .

[0073] Therefore, the slider structure 200 can drive the slider 210 to move relative to the frame body 110 through the second driving assembly 230, so that the slider 210 and the third bending member 220 move toward the second bending member 120 together, and the operation is simple and convenient.

[0074] Reference Figure 6 As shown, in some embodiments, the slider 210 has a first bending groove 211, the extension direction of the first bending groove 211 is consistent with the moving direction of the third bending member 220, and the first end of the extension direction of the first bending groove 211 has a first opening, and the first opening faces the second bending member 120.

[0075] The third bending member 220 is connected to the second end of the first bending groove 211 in the extending direction. When the slider 210 moves, part of the second bending member 120 is inserted into the first bending groove 211 through the first opening.

[0076] Therefore, when the second driving component 230 drives the slider 210 to move relative to the frame body 110 toward the second bending piece 120, the second bending piece 120 can be inserted into the first bending groove 211 through the first opening, and the second bending piece 120 can move along the extension direction of the first bending groove 211 until it abuts against the second bending piece 120, so that the second bending piece 120, the third bending piece 220 and the first bending groove 211 jointly bend the straight metal sheet to form a V-shaped metal sheet.

[0077] Figure 7 for Figure 2 Schematic diagram of the structure of the second drive assembly. Figure 7As shown, in a specific implementation, the second driving assembly 230 includes a first driving rod 231 and a first connecting member 232, the first connecting member 232 includes a first connecting rod 2321 and at least two second connecting rods 2322, the frame body 110 has a first avoidance groove 112, the first driving rod 231 is connected to the first end of the first connecting rod 2321, the first connecting rod 2321 is inserted into the frame body 110 through the first avoidance groove 112, and the second end of the first connecting rod 2321 is hinged to the first end of each second connecting rod 2322, the second end of a second connecting rod 2322 is hinged to the frame body 110, and the second end of another second connecting rod 2322 is hinged to the slider 210.

[0078] In this way, the second driving assembly 230 is configured to drive the slider 210 to move relative to the frame body 110 by operating the first driving rod 231, and is configured to connect the first driving rod 231 and the slider 210 by configuring the first connecting member 232, so that the driving force is transmitted from the first driving rod 231 to the slider 210.

[0079] For example, the first connecting member 232 may include a first connecting rod 2321 and two second connecting rods 2322. For the sake of convenience, the second connecting rod 2322 hinged to the frame body 110 is recorded as a first sub-connecting rod 2322a, and the second connecting rod 2322 hinged to the slider 210 is recorded as a second sub-connecting rod 2322b. In this way, by connecting the first end of the first connecting rod 2321 to the first driving rod 231, the second end of the first connecting rod 2321 is simultaneously connected to the first sub-connecting rod 2322a and the second sub-connecting rod 2322b, so that the driving force of the first driving rod 231 is transmitted along the first connecting rod 2321 to the first sub-connecting rod 2322a and the second sub-connecting rod 2322b, and drives the first sub-connecting rod 2322a and The second sub-connecting rod 2322b rotates relatively, and is connected to the frame body 110 through the first sub-connecting rod 2322a and the second sub-connecting rod 2322b to connect the slider 210, so that when the first sub-connecting rod 2322a and the second sub-connecting rod 2322b rotate relatively, the slider 210 can be moved relative to the frame body 110, that is, when the second end of the first sub-connecting rod 2322a and the second end of the second sub-connecting rod 2322b approach each other, the slider 210 moves toward the second bending member 120 relative to the frame body 110, and when the second end of the first sub-connecting rod 2322a and the second end of the second sub-connecting rod 2322b move away from each other, the slider 210 moves away from the second bending member 120 relative to the frame body 110.

[0080] Figure 8 for Figure 6 Refer to the top view of Figure 2 and Figure 8As shown, in some embodiments, at least two first bending members 310 include a first sub-bending member 311 and a second sub-bending member 312, and the first driving assembly 320 includes two second driving rods 321, a second connecting member 322 and a third connecting member 323, the second connecting member 322 and the third connecting member 323 are both connected to the frame, a second driving rod 321 is connected to the first sub-bending member 311 through the second connecting member 322, and the second driving rod 321 drives the first sub-bending member 311 to move toward the slider 210 under the action of an external force, so that the first sub-bending member 311 and the slider 210 bend the metal sheet together;

[0081] Another second driving rod 321 is connected to the second sub-bending member 312 through a third connecting member 323. Under the action of external force, another second driving rod 321 drives the second sub-bending member 312 to move toward the slider 210, so that the second sub-bending member 312 and the slider 210 bend the metal sheet together.

[0082] For the sake of convenience, the second driving rod 321 connected to the first sub-bending member 311 is recorded as the first sub-driving rod 3211, and the second driving rod 321 connected to the second sub-bending member 312 is recorded as the second sub-driving rod 3212. In this way, the first sub-driving rod 3211 can be operated to drive the second connecting member 322 to move, so as to drive the first sub-bending member 311 to move toward the slider 210, and make the first sub-bending member 311 abut against the slider 210, thereby bending the V-shaped metal sheet into a W-shaped metal sheet. Afterwards, the second sub-driving rod 3212 is operated to drive the third connecting member 323 to move, so as to drive the second sub-bending member 312 to move toward the slider 210, and make the second sub-bending member 312 abut against the slider 210, thereby bending the W-shaped metal sheet into a five-layer laminated metal sheet test sample.

[0083] Reference Figure 2 and Figure 6 As shown, in a specific implementation, the slider 210 also has a second bending groove 212 and a third bending groove 213.
