Technical Field
[0001] The utility model belongs to the technical field of sample processing, and relates to a bending experiment device for metal thin plate samples. Background Art
[0002] At present, in the process of thin plate production inspection, according to production needs, it is bent to a fixed angle. The bending test is the simplest method that can be formed at one time, but its deformation process is complex. During the bending process, the material deformation can expose the surface defects of the material when the punch and the die approach each other.
[0003] When the thin plate sample is subjected to a V-shaped bending test according to the process requirements, the bending needs to fix the bending angle, and after removing the test force, the convex surface is inspected to check whether there are cracks or obvious surface defects. At present, the existing bending devices cannot well bend the metal plate into a corresponding V shape in one go, and during the bending process, other parts of the metal plate except the bent part are also prone to bending, affecting the experimental results.

[0004] The purpose of the utility model is to provide a bending experiment device for metal thin plate samples aiming at the problems existing in the prior art.
[0005] For this reason, the utility model adopts the following technical solutions:
[0006] A bending experiment device for metal thin plate samples, characterized in that it includes a bracket, a pressing module is arranged on the bracket, a V-shaped groove is arranged on the pressing module, a pressing line is formed at the bottom end of the groove, a hydraulic cylinder is arranged above the groove, the hydraulic cylinder is fixed on the bracket, a pressing plate is fixed at the bottom end of the hydraulic cylinder, and a pressing edge parallel to the pressing line is formed at the bottom end of the pressing plate.

[0013] The beneficial effects of the present utility model are as follows: A pressing groove in a V-shaped structure is provided on the pressing module. The pressing edge at the bottom end of the pressing plate is driven by a hydraulic cylinder to press the metal thin plate on the pressing module, so that the metal thin plate is bent into a V-shaped structure adapted to the pressing groove. The bending angle and position are accurate, the bending effect is good, and other parts of the metal plate are not easily bent; the structure is simple, and the use method is convenient, efficient and fast.

[0015] In the figure, 1 - support, 2 - pressing module, 3 - pressing groove, 4 - pressing line, 5 - hydraulic cylinder, 6 - pressing plate, 7 - pressing edge, 8 - side pressing plate, 9 - connecting rod. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0016] The following will describe the present utility model in detail with reference to the accompanying drawings:
[0017] As Figure 1 shown, a bending experiment device for a metal thin plate sample, characterized in that it includes a support 1, a pressing module 2 is provided on the support 1, the upper surface of the pressing module 2 is horizontally arranged, a pressing groove 3 in a V-shaped structure is provided on the pressing module 2, and the metal plate can be bent into a V-shaped structure adapted to the pressing groove 3 through the pressing groove 3. The bottom end of the pressing groove 3 forms a horizontally arranged pressing line 4, which can cause the metal plate to be newly bent at the corresponding position of the pressing line 4. Above the pressing groove 3, a vertically arranged hydraulic cylinder 5 is provided. The hydraulic cylinder 5 is fixed on the support 1, and a vertically arranged pressing plate 6 is fixed at the bottom end of the hydraulic cylinder 5. The hydraulic cylinder 5 can drive the pressing plate 6 to move up and down in the vertical direction to press the metal thin plate on the pressing module 2, so that the metal thin plate enters the pressing groove 3 and is bent. The bottom end of the pressing plate 6 forms a pressing edge 7 corresponding to and parallel to the pressing line 4. When pressing the metal thin plate, the pressing edge 7 contacts the metal thin plate and presses the middle part of the metal thin plate. In order to prevent the middle part of the metal thin plate from being cut off or a pressing mark from being generated in the middle part of the metal thin plate during pressing, the pressing edge 7 is in an arc-shaped structure.
[0018] In order to make the bending angle of the metal thin plate adapted to the pressing groove 3, a side pressing plate 8 parallel to the inner wall of the pressing groove 3 is provided on each side of the pressing plate 6. After pressing is completed, the side pressing plate 8 can make the metal thin plate abut against the inner wall of the pressing groove 3, so that the metal thin plate is bent into a V-shaped structure adapted to the pressing groove 3. Specifically, a connecting rod 9 is provided on each side of the pressing plate 6, and the side of the connecting rod 9 away from the pressing plate 6 is connected to the side pressing plate 8.
[0019] The usage method of the present utility model is as follows:
[0020] When bending, first place the metal sheet on the upper surface of the pressing module, and make the middle bending part of the metal sheet directly above the pressing line 4 at the bottom of the pressing groove 3. Then, the hydraulic cylinder 5 can be started, and the pressing plate 6 is driven to move downward through the hydraulic cylinder 5. The metal sheet is pressed into the pressing groove 3 through the pressing edge 7 at the bottom end of the pressing plate 6, causing the metal sheet to bend. During the process of the metal sheet being pressed into the pressing groove 3, the metal sheet bends under the action of the pressing plate 6. When the pressing line 4 of the pressing plate 6 reaches the bottom end of the pressing groove 3, the side pressing plate 8 can squeeze the corresponding position of the metal sheet against the inner wall of the pressing groove 3, causing the metal sheet to complete the bending operation, and the bending shape is adapted to the V-shaped structure of the pressing groove 3.
[0021] Using this device to bend the metal sheet has good bending effect, high speed, and accurate bending angle and position.
