Description
Technical Field
[0001] The utility model belongs to the technical field of bending test devices, and more specifically, particularly relates to a bending test device for an automobile anti-collision beam. Background Art
[0002] The main function of a car's anti-collision beam is to protect some important parts of the car body, such as the front and rear headlights, the hood, the exhaust pipe, etc. The main function is to protect the car body. In fact, to put it bluntly, it is to reduce maintenance costs after a collision. At present, a three-point bending test method is usually used to test car anti-collision beams. That is, the anti-collision beam specimen is placed on two supporting points at a certain distance, and a downward load is applied to the specimen at the midpoint of the two supporting points. When the three contact points of the specimen form two equal moments, three-point bending occurs. However, based on the prior art, it is found that when the existing bending test device is used, after fixing the anti-collision beam, it usually directly applies pressure to the midpoint position. However, when the applied pressure exceeds the bearing capacity of the anti-collision beam, the beam body will generate a large rebound force and separate from the test structure, thereby causing damage to the surrounding structure.
