Description

Technical Field

[0001] This utility model relates to the field of ring forging testing technology, specifically a hardness tester for testing ring forgings. Background Technology

[0002] Ring forgings are a product of the forging industry and a type of forging. They are made by applying external force to metal billets (excluding plates) and shaping them into ring-shaped objects with appropriate compressive force through plastic deformation. This force is typically achieved by using a hammer or pressure. The forging process creates a fine granular structure and improves the physical properties of the metal. As an industrial product, to ensure the quality of ring forgings, it is necessary to test their hardness, yield strength, tensile strength, impact resistance, etc.

[0003] According to patent document CN220961053U, a hardness tester for testing annular forgings is disclosed, which includes: a mounting base with a cavity inside; a motor mounted on the outer wall of the mounting base; a lead screw at the output end of the motor; the lead screw passing through the mounting base and rotatably mounted inside the cavity; two symmetrically distributed adjusting plates at the bottom of the mounting base; the adjusting plates passing through the mounting base and mounted on the outer wall of the lead screw; and the adjusting plates being able to slide at the bottom of the mounting base by rotating the lead screw; and a detection probe for detecting hardness being provided on the inner side of the adjusting plates.

[0004] Existing testing equipment is inconvenient for assisting in the positioning of materials during operation, which makes the materials prone to displacement. This causes the testing probe to fail to ensure that the force is applied vertically to the arc surface of the ring forging, thus affecting the test results. In addition, it does not have an auxiliary cleaning function, and the adhering impurities will also affect the accuracy of the test. Utility Model Content

[0005] The purpose of this invention is to provide a hardness tester for testing ring forgings, in order to solve the problems mentioned in the background art, such as the inconvenience of assisting in the positioning of materials during operation, which makes the materials easy to deviate, causing the testing probe to fail to ensure that the force is applied vertically to the arc surface of the ring forging, thus affecting the test results. Moreover, it does not have an auxiliary cleaning function, and the adhering impurities will also affect the accuracy of the test.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hardness tester for testing annular forgings, comprising a worktable, an auxiliary mechanism provided on one side of the worktable, the auxiliary mechanism comprising a first motor, one side of the first motor being fixedly connected to the worktable, a frame being fixedly connected to the output end of the first motor, an electric slide being fixedly connected to the central axis at the bottom of the inner cavity of the frame, a connecting seat being fixedly connected to the top of the electric slide, movable rods being movably connected to both sides of the connecting seat, an adjusting seat being movably connected to one side of the movable rods, a vertical plate being fixedly connected to one side of the adjusting seat, a fixed plate being fixedly connected to the top of the vertical plate, anti-slip pads being fixedly connected to both sides of the fixed plate, a threaded sleeve being provided on one side of the fixed plate, a nut being fixedly connected to the right side of the bottom of the threaded sleeve, and a brush roller being threadedly connected to the inner cavity of the nut.
