Curve detection device and detection method

Abstract

The invention discloses a curve detection device having multi-point curve detection loading manners and a curve detection method. The curve detection device comprises a base, an upper pressing block, curve pressure heads, a horizontal position adjustment device, at least two support blocks and two movement seats, wherein one ends of the support blocks are mounted on the upper pressing block in a sliding manner; the curve pressure heads are mounted at the other ends of the support blocks; the movement seats are mounted on the upper surface of the base in a sliding manner through the horizontal position adjustment device; backup rollers are arranged on the movement seats. The detection method comprises the following steps: (1) mounting the detection device; (2) mounting a test piece, and adjusting the positions of the support blocks and the movement seats; (3) starting a testing machine for detection. With adoption of the detection device and method, the detection device can meet the loading manners of various curve detection, avoids the situation that different curve loading manners adopt different loading devices, is simple in structure and excellent in applicability and reduces the cost; with adoption of the detection device, the operating processes are simplified, the operation is simple, and the reliability is excellent.

Description

technical field [0001] The invention relates to the field of mechanical detection, in particular to a bending detection device and a detection method. Background technique [0002] Known: The detection of bending is mainly used to determine the mechanical properties such as the bending strength of brittle and low plastic materials (such as cast iron, high carbon steel, tool steel, etc.), and can reflect the deflection of the plastic index, and can also be used to measure the deflection of the material Surface Quality. The bending experiment was carried out on a universal material machine, and there were two loading methods of three-point bending and four-point bending. At present, most of the three-point bending device, the four-point bending device and the ordinary bending device used to measure the surface quality of the material are used separately; one device can only realize one kind of bending detection, so it is extremely inconvenient to use, and it is difficult for ...
