[0018] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.
[0019] The purpose of this invention is to provide a device for determining the bending angle of metal materials, thereby solving the problems existing in the prior art, effectively solving the problem of accurately determining the bending angle of metal materials during bending tests, and improving test efficiency and the accuracy of result judgment.
[0020] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0021] This invention provides a device for determining the bending angle of a metallic material, such as... Figs. 1-2 As shown, the device includes: an elastic recovery component, a dial 5, and a pointer 6. The elastic recovery component can bend under external force and return to a straight state after the external force is removed. The dial 5 is fixedly connected to one end of the elastic recovery component. The pointer 6 is fixedly connected to the end of the elastic recovery component away from the dial 5. The bending angle of the elastic recovery component is determined by the movement of the elastic recovery component on the dial 5 during bending and the reading on the dial 5 corresponding to the pointer 6. The device can intuitively present the bending angle of the elastic recovery component through the reading on the dial 5 by the pointer 6. Through the characteristics of the elastic recovery component, the bending process of metal materials can be simulated and quantitatively displayed, providing a basis for the accurate determination of the bending angle of metal materials.
[0022] In a preferred embodiment, the elastic recovery element is a spring sheet 3. The spring sheet 3 has good elasticity and recovery properties, enabling it to bend and deform relatively accurately under external force and quickly return to its original shape after the external force is removed. This characteristic ensures good repeatability of the device in multiple measurements, providing stable and accurate measurement results and improving the reliability of the device's measurements. At the same time, the spring sheet 3 is relatively easy to obtain and process, reducing the manufacturing cost of the device.
[0023] In a preferred embodiment, the device for determining the bending angle of the metal material further includes a first connecting rod 4. The first connecting rod 4 is vertically fixedly connected to one end of the elastic recovery member and the other end is fixedly connected to the pointer 6. The first connecting rod 4 serves to connect the elastic recovery member and the pointer 6, accurately transmitting the bending action of the elastic recovery member to the pointer 6. The vertical fixed connection ensures a stable force transmission direction, allowing the pointer 6 to move precisely on the scale 5 according to the deformation of the elastic recovery member when it bends, thereby improving the accuracy and sensitivity of the measured angle.
[0024] In a preferred embodiment, the device for determining the bending angle of the metal material further comprises a second connecting rod, which is fixedly connected with the elastic recovery member perpendicularly away from one end of the first connecting rod 4, and the first connecting rod 4 and the second connecting rod are in the same direction. The arrangement of the second connecting rod further enhances the stability of the device structure, cooperates with the first connecting rod 4, and enables the elastic recovery member to remain in a relatively stable plane during bending, thereby reducing measurement errors caused by unstable factors such as left and right shaking. At the same time, the design in the same direction ensures the consistency of force transmission and the overall action of the device, which helps to improve the measurement accuracy and overall reliability of the device.
[0025] In a preferred embodiment, the scale on the dial 5 is a non-uniform scale, and the scale on the dial 5 is a bending angle value calibrated through multiple different angle experiments. The design of non-uniform scale can be customized according to the complex relationship between the bending angle and the bending state of the elastic recovery member in actual measurement. Through multiple different angle experimental calibration, the scale can more accurately correspond to the actual bending angle of the elastic recovery member. Compared with uniform scale, this calibrated non-uniform scale can improve the measurement accuracy in different angle measurement areas, especially in some key angle range, which can more accurately reflect the true bending angle of the metal material, and meet the diversified accuracy requirements in actual measurement.
[0026] In a preferred embodiment, the pointer 6 is made of metal, which has certain rigidity and stability and is not easy to deform or damage during use. This ensures that the pointer 6 can accurately indicate the reading on the dial 5 when moving with the elastic recovery member, prolongs the service life of the pointer 6, reduces measurement errors caused by pointer 6 deformation and other problems, and improves the long-term accuracy and reliability of the device measurement results.
[0027] In a preferred embodiment, the elastic recovery member, the first connecting rod 4, the second connecting rod, the pointer 6 and the dial 5 are all fixedly connected by welding. The welding fixed connection ensures the firm and reliable connection between the components, avoiding the loosening or separation during use. This stable connection structure can ensure that the relative positions between the components remain unchanged during long-term use and multiple measurements, thereby effectively ensuring the accuracy and stability of the device measurement, and reducing the influence of component connection problems on the measurement results.
[0028] During use, firstly, the sample to be detected is placed on the two rods 1, then the spring sheet 3 is placed on the two rods 1 parallel to the sample, the bending pressure head 2 continuously applies force to the sample and the spring sheet 3 to make the sample and the spring sheet 3 bend, the pointer 6 moves on the scale disc 5, the position of the pointer 6 on the scale disc 5 is observed, the sample continues to bend until the bending angle stops, the sample is removed, and the outer surface of the sample is judged by naked eyes to determine whether the metal material is qualified in plastic bending capacity at the bending angle.
[0029] The principle and implementation mode of the present application are described by using specific examples in the present application, and the above embodiment is only used to help understand the method and core idea of the present application; meanwhile, according to the idea of the present application, the specific implementation mode and application range will be changed by the general technical personnel in the field. In conclusion, the content of the present application should not be understood as a limitation of the present application.
