Description

Technical Field

[0001] The utility model belongs to the technical field of electrician bushings, and in particular relates to a bending and flatness testing device for electrician bushings. Background Art

[0002] The electrical conduit bending test is a material mechanical property test for electrical conduits. The test is mainly used to determine the mechanical properties of electrical conduits when subjected to bending loads. During the test, the electrical conduits will be bent to a certain angle and then observed to see if cracks or other forms of deformation occur. The purpose of this test is to test the performance of the electrical conduits in a bent state, thereby ensuring that they can withstand the expected bending stress in actual applications without damage or performance degradation.

[0003] When the conventional electrical conduit bending test device is used, the electrical conduit may splash during the bending process. This is mainly because during the bending process, the metal inside the conduit may be squeezed and sheared, causing some metal particles or fragments to pop out from the surface or inside of the conduit, which is easy to cause harm to the surrounding workers.

[0004] Therefore, it is necessary to provide an electrical conduit bending and flattening test device that can protect workers to solve the above technical problems. Utility Model Content

[0010] Preferably, a bottom plate is fixedly mounted on the bottom of the installation frame, a plurality of tripods are fixedly mounted on the top of the bottom plate, and one side of the plurality of tripods is fixedly connected to the installation frame.

[0011] Preferably, a shell is fixedly mounted on the top of the top plate, the shell is located outside the motor, and the shell is rotatably connected to the screw rod.

[0012] Preferably, the installation frame is configured to be mouth-shaped, and the observation window is made of plastic.

[0013] Compared with the related art, the electrical casing bending and flattening test device provided by the utility model has the following beneficial effects:

[0014] Compared with the prior art, the electrical conduit bending and flattening test device provided in the present invention can clamp the electrical conduit to be tested tightly between the first roller and the pressing mechanism through the use of a hydraulic cylinder. After clamping, the protective mechanism can be conveniently used to enclose the periphery of the electrical conduit, and the electrical conduit can be bent through the pressing mechanism.
