Description

Technical Field

[0001] The utility model belongs to the technical field of technical impact detection, and specifically relates to a metal Charpy impact detection device and a processing system. Background Art

[0002] The Charpy impact test is a test used to determine the notch sensitivity of metal materials. A metal sample of a certain shape and size is prepared so that it has a U-shaped notch or a V-shaped notch. It is placed in a simply supported beam state on a Charpy impact tester. The pendulum lifted by the tester is used to impact the sample once, so that the sample breaks along the notch. The absorbed energy of the sample is calculated by the height difference when the pendulum rises again when it breaks, which is Aku and Akv. Impact tests can be performed at different temperatures. A large absorbed energy value indicates that the material has good toughness and is insensitive to notches or other stress concentrations in the structure.

[0003] When performing a technical Charpy impact test, the metal sample needs to be placed on two anvils so that the notch of the metal sample is centered between the two anvils and the notch corresponds to the pendulum to meet the test requirements.

[0004] In the prior art, a Chinese utility model patent document with authorization announcement number CN208833585U discloses a centering tool for Charpy impact test, which realizes the centering positioning of the metal sample by matching the convex part on the side of the positioning hole with the notch on the metal sample; in this positioning method, the positioning block and the detection device are designed to be split, which is easy to lose and has poor convenience of use.

[0011] The centering rod is slidably arranged at the end of the supporting arm along the vertical direction.

[0012] A handle is fixedly arranged on the upper end of the centering rod.

[0013] A mounting step is arranged on the top of the base, and the cutting board is detachably fixedly assembled on the top of the mounting step by bolts.

[0014] The baffle has an inner side surface of the baffle and a back side surface of the baffle, and an included angle α between the inner side surface of the baffle and the back side surface of the baffle is 100-102°.

[0015] A processing system comprises the metal Charpy impact detection device as described in any one of the above items.
