Problems solved by technology

For ordinary colleges and universities, the common problem is that funds are tight and it is impossible to purchase a variety of testing equipment. For hardness testing, static afterburning equipment and dynamic afterburning equipment have huge differences in structure and cannot be replaced by each other.

Abstract

The invention discloses a hardness detection device and method. The hardness detection device includes a hydraulic detection head assembly (3) and a placement tray (5), wherein materials to be detected (8) are arranged between the hydraulic detection head device assembly (3) and the placement tray (5), and a hand shank (9) used for triggering hardness detection operation is further included. The hardness detection device integrates two functions of static and dynamics stress application detection through switch of a valve and using of a hydraulic energy accumulator, one device dual using can be realized, compared with traditional Brinell hardness detection, using performance is improved, and the cost is lowered greatly.

Description

technical field [0001] The invention relates to a physical parameter detection device, in particular to a hardness detection device and a detection method for Brinell hardness detection. Background technique [0002] The so-called hardness of a material refers to: the ability of a material to resist objects harder than it without being damaged when pressed in, or the ability of a material to resist plastic deformation and elastic deformation. Brinell hardness is a standard that expresses the hardness of materials. Measured by Brinell hardness tester. It was first proposed by the Swedish J.A.Brinell, so it is called Brinell hardness. A quenched steel ball with a diameter of D is pressed into the surface of the metal material to be tested with a certain load P, and the load is removed after a period of time. The ratio of the load P to the indentation surface area F is the Brinell hardness value, denoted as HB. [0003] At present, Brinell hardness testing equipment has been...
