Description

Technical Field

[0001] The utility model relates to a jig, in particular to a die casting flanging test tool. Background Art

[0002] In the past, the rubber damping of the shock absorbing components of automobile engines was assembled and sealed by two separate seals. However, the shock absorbing components are no longer sealed by assembled seals, but the rubber damping is closed and sealed by riveting of the shock absorbing components themselves. Under this structure, the mechanical properties of the raw materials of the product itself are higher than those of the previous assembled sealing structure.

[0003] Flanged and riveted castings are particularly prominent in current engine shock absorption applications. Their structure is significantly different from conventional shock absorber brackets and shock absorber mounts. Under the premise of ensuring the extrusion strength of the parts, it is necessary to reduce cracking during the flanging process and ensure that the position of the parts after flanging is not easily pressed out. Therefore, the mechanical property testing before mass production is particularly important.

[0004] The amount of spraying during the aluminum alloy die-casting process, the fluctuation of the aluminum liquid temperature, and the fluctuation of the raw material composition will all cause the problem of flange cracking. However, there is no special fixture in the existing technology to verify the mechanical properties of such aluminum castings, such as whether the flange will crack, whether the extrusion strength after flanging is qualified, etc. The above mechanical properties can only be verified when the assembly is made at the customer's place. As a result, it is impossible to accurately judge whether the product can fully meet the requirements during the production of aluminum castings, resulting in quality risks in the final assembled product. Utility Model Content

[0005] The technical problem to be solved by the utility model is to overcome the defects in the prior art and to provide a die casting flanging test tool.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A die-casting flanging test tool, the die-casting to be tested has a main body and a support arm extending upward along the main body, the edge of the support arm is folded downward to form a flanging, and its characteristics are: the die-casting flanging test tool includes a base and a pressure head adapted to the base, the base has a hollow chamber adapted to the main body, and a support table for supporting the support arm, the side of the support table is provided with an avoidance groove for avoiding the flanging; the pressure head includes an annular pressure block extending downward, the lower surface of the annular pressure block is opposite to the upper surface of the base, and the outer surface of the annular pressure block is provided with an avoidance position for avoiding the support table.

[0008] Wherein, the upper surface of the base is provided with a positioning column extending upward, and the lower surface of the pressure head is provided with a positioning groove corresponding to the positioning column.

[0009] Wherein, a limiting step adapted to the outer surface of the body is formed on the inner side of the hollow chamber.

[0010] Wherein, a first tooling installation screw hole is provided on the lower surface of the base.

[0011] Wherein, the upper surface of the pressing head is provided with a second tooling installation screw hole.

[0012] The beneficial effects of the above technical solution: the die-casting flanging test tooling of the utility model has a compact structure and is easy to fix. It can quickly complete the support of the workpiece to be tested, thereby completing destructive testing to verify the flanging effect. Problems can be discovered and improved in time during the production process, which is convenient for reflecting the effect and performance of the workpiece flanging before batch assembly, thereby ensuring the yield rate of batch assembly.

[0017] The present invention is further described below by way of embodiments, but the present invention is not limited to the scope of the embodiments.

[0018] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0019] like Figure 1 As shown, the die casting to be tested has a body 100 and three groups of arms 110 extending upwardly from the body 100, and the side of each arm 110 is formed with a flange 111 folded downward. Figure 1-4As shown, the die casting flanging test fixture in this embodiment includes a base 1 and a pressure head 2 adapted to the base 1, the base 1 has a hollow chamber 16 adapted to the body 100, and a support platform 11 for supporting the support arm 110, and the side of the support platform 11 is provided with an avoidance groove 12 for avoiding the flanging 111. In order to ensure effective support of the support arm 111 during the test, a limiting step 15 adapted to the outer surface of the body 100 is formed on the inner side of the hollow chamber 16. The pressure head 2 includes an annular pressing block 22 extending downward, the lower surface of the annular pressing block 22 is opposite to the upper surface of the base 1, and the outer surface of the annular pressing block 22 is provided with an avoidance position 221 for avoiding the support platform 111.

[0020] In order to ensure that the base 1 and the pressure head 2 always maintain linear trajectory movement during the pressure damage test, the upper surface of the base 1 is provided with an upwardly extending positioning column 13, and the lower surface of the pressure head 2 is provided with a positioning groove 21 corresponding to the positioning column 13.

[0021] A first tooling installation screw hole 14 for fixing the base to a power part (not shown) or a platform (not shown) of a test system is provided on the lower surface of the base 1. In contrast, a second tooling installation screw hole 23 for fixing the pressure head 2 to a platform or a power part of a test system is provided on the upper surface of the pressure head 2.

[0022] Before testing, place the body of the die-casting to be tested into the hollow chamber 16, ensure that the arm 110 is located on the support platform 11, and the flange 111 is located in the avoidance groove 12. After starting the power component, the pressure head 2 moves downward and performs the test on the die-casting together with the base 1. The power component and platform described in this embodiment can be commercially available products. For example, a hydraulic cylinder is used as the power component. The base or the pressure head is fixed to the hydraulic cylinder through the first or second mounting screw holes on the surface, the nuts and the necessary fixing auxiliary mechanism, or it is fixed to the hydraulic cylinder by welding, which will not be described in detail here. The test fixture in this embodiment is used to clamp and squeeze the workpiece to be tested during the test, and the mechanical data collection, feedback and analysis during the test can adopt existing technologies.
