Description

Technical Field

[0001] This utility model relates to the field of materials testing, and in particular to a springback testing system. Background Technology

[0002] In the electric vehicle field, tungsten alloys have potential applications due to their high density, high strength, and good plasticity. Especially in the buffer structures or protective devices of battery packs, tungsten alloys can effectively prevent battery damage during collisions or vibrations. Therefore, it is crucial to test and evaluate the tensile, compressive, and resilience properties of these specially shaped tungsten alloy products. These tests can comprehensively assess the mechanical properties of the material in practical use, ensuring its reliability and safety under complex operating conditions.

[0003] Currently, tensile and compressive testing of metallic materials is primarily performed using electronic universal testing machines. During testing, the machine typically uses clamping or threaded connections to fix standard rod-shaped or plate-shaped specimens, applying tensile or compressive forces and measuring the material's mechanical properties. Common clamping methods include wedge clamps, flat clamps, V-clamps, and threaded clamps, which are suitable for standard-sized specimens. However, for non-standard workpieces or samples with special dimensions, such as tungsten alloy buffer structures or protective devices used in electric vehicle battery packs, existing clamping fixtures often have limitations and cannot meet specific testing requirements. Furthermore, there are currently no corresponding testing methods in the industry for testing under specific tensile and compressive forces. Utility Model Content

[0004] The purpose of this invention is to provide a springback testing system that enables testing of various C-shaped steel materials.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rebound measurement system, the system being used to measure a product under test, the product under test including a bottom support, a support beam, and a top support, the support beam being located between the bottom support and the top support, comprising: a support mechanism for supporting the product under test, the product under test being connected to the support mechanism; a telescopic mechanism located above the support mechanism, the telescopic mechanism being capable of compressing or stretching the top support; and a testing mechanism, the testing end of the testing mechanism contacting the top support, the testing mechanism being capable of detecting the displacement distance of the top support.

[0006] Furthermore, the telescopic mechanism includes a telescopic subunit and a stretching subunit, which are connected by a first wedge clamp. The telescopic subunit can drive the stretching subunit to move in the vertical direction.

[0007] Furthermore, the stretching subunit includes a pull head and a pressure head, and the first wedge clamp is connected to the pull head or the pressure head. When the pull head is connected to the first wedge clamp, the telescopic mechanism can stretch the top support of the product. When the pressure head is connected to the first wedge clamp, the telescopic mechanism can compress the top support of the product.

[0008] Furthermore, the pull head is provided with a through groove, and the top support of the product can extend into the through groove. The lower surface of the through groove is provided with a first support ball. When the pull head moves upward, the first support ball contacts the lower surface of the top support of the product.

[0009] Furthermore, the lower surface of the pressure head is provided with a second support ball, which comes into contact with the upper surface of the product top support when the pressure head moves downward.

[0010] Furthermore, the support mechanism includes a second wedge clamp, a support column, and a base plate. One end of the support column is connected to the second wedge clamp, and the other end of the support column is connected to the base plate. The bottom support of the product is connected to the base plate.

[0011] Furthermore, the testing mechanism includes a support arm and a digital dial indicator. One end of the support arm is connected to the base plate, and the other end of the support arm is connected to the digital dial indicator. The testing end of the digital dial indicator is in contact with the lower surface of the top support of the product.

[0012] Analysis shows that this utility model discloses a springback testing system. The testing system of this utility model can effectively test the compressive springback of "C" shaped products, while preventing unexpected deformation of the product during the test and improving the accuracy of the test results.

[0022] like Figures 1-4As shown, according to an embodiment of the present invention, a springback testing system is provided. The testing system is used to measure the product 8 to be tested. The product 8 to be tested includes a bottom support, a support beam, and a top support. The support beam is located between the bottom support and the top support. Typically, the product 8 to be tested is C-shaped. The product 8 to be tested can be made of tungsten alloy or other materials, but may have other shapes depending on the actual situation.

[0023] The testing system specifically includes:

[0024] The support mechanism is used to support the product under test 8, and the product under test 8 is connected to the support mechanism.

[0025] Furthermore, the support mechanism includes a second wedge-shaped clamp 11, a support column 1, and a base plate 2. One end of the support column 1 is connected to the second wedge-shaped clamp 11, and the other end of the support column 1 is connected to the base plate 2. The bottom support of the product is also connected to the base plate 2. The support column 1 can be connected to the base plate 2 with screws to form a stable support structure. The other end of the support column 1 is connected to and locked to the second wedge-shaped clamp, thereby providing a stable support foundation for the entire testing system and ensuring the stability of each structure during the test. The high-rigidity support mechanism is used to horizontally support the bottom of the product to be tested 8. In specific use, the product to be tested 8 is placed on the base plate 2. A guard plate 3 can be installed on the product support beam. The test product has threaded holes, and the base plate 2 and guard plate 3 also have threaded holes. The product support beam can be connected to the guard plate 3 and the bottom support of the product can be connected to the base plate 2 with screws and nuts. The function of the guard plate 3 is to prevent the side of the test product from deforming during the tensile test, so as to avoid affecting the test accuracy of the rebound amount.

[0026] The telescopic mechanism, located above the support mechanism, can compress or extend the top support of the product. Suspended directly above the support mechanism, the telescopic mechanism can achieve vertical reciprocating motion via hydraulic drive. It can actively compress downwards or extend upwards the top support of the product, simulating the pressure or tension the product experiences under actual working conditions.

[0027] The telescopic mechanism includes a telescopic subunit and a stretching subunit, which are connected by a first wedge clamp 10. The telescopic subunit can drive the stretching subunit to move vertically. The stretching subunit includes a pull head 6 and a pressure head 4. The first wedge clamp 10 is connected to either the pull head 6 or the pressure head 4. When the pull head 6 is connected to the first wedge clamp 10, the telescopic mechanism can stretch the top support of the product. When the pressure head 4 is connected to the first wedge clamp 10, the telescopic mechanism can compress the top support of the product.

[0028] Specifically, during the tensile test, the pull head 6 is installed below the first wedge-shaped clamp 10. When the telescopic subunit rises, the pull head 6 pulls the top support of the product upwards. During the compression test, the pressure head 4 replaces the pull head 6. When the telescopic subunit depresses, the pressure head 4 depresses the top support of the product.

[0029] Furthermore, the pull head 6 is provided with a through groove, into which the top support of the product can extend. A first support ball 5 is provided on the lower surface of the through groove. When the pull head 6 moves upward, the first support ball 5 contacts the lower surface of the top support of the product. A second support ball 7 is provided on the lower surface of the pressure head 4. When the pressure head 4 moves downward, the second support ball 7 contacts the upper surface of the top support of the product. The first support ball 5 and the second support ball 7 are typically tungsten alloy balls. Due to the high strength and high hardness of tungsten alloys, tungsten alloy balls are used to ensure that the point of force application is as concentrated as possible and that the product is not deformed by compression.

[0030] During the tensile test, the slider 6 is fitted onto the product 8 to be tested and connected and locked to the first wedge-shaped clamp. This ensures that the first support ball 5 embedded within the slider 6 has reached the designated force application position, guaranteeing the accuracy and uniformity of the applied force. During the compression test, the indenter 4 is connected and locked to the first wedge-shaped clamp of the testing machine. Again, this ensures that the first support ball 5 embedded within the slider 6 has reached the designated force application position.

[0031] The testing mechanism has its detection end in contact with the top support of the product, and it can detect the displacement distance of the top support. The testing mechanism includes a support arm and a digital dial indicator 9. One end of the support arm is connected to the base plate 2, and the other end of the support arm is connected to the digital dial indicator 9. The detection end of the digital dial indicator 9 is in contact with the lower surface of the top support of the product.

[0032] During the test, place the digital dial indicator 9 with its pointer touching the lower surface of the product 8 under test and zero it. After the telescopic mechanism starts working and applies the specified force, record the dial indicator reading. After the telescopic mechanism unloads (i.e., no longer in contact with the product 8 under test), record the dial indicator reading again. The difference between the two readings is the tensile springback or compressive springback.

[0033] As can be seen from the above description, this utility model improves the overall structural stability through the optimized design of the support column 1, base plate 2, guard plate 3, pressure head 4, and pull head 6, effectively solving the problem of "C-shaped" products being undetectable in conventional tensile and compression techniques due to the inapplicability of threaded or wedge-shaped clamps. The guard plate 3 prevents lateral deformation of the product, while the pressure head 4 and pull head 6 apply force precisely, ensuring high-precision testing. The overall structure is stable, reducing test deviations; the tooling design is simple, and installation and disassembly are convenient, improving testing efficiency.

[0034] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
