Description

Technical Field

[0001] This utility model relates to the technical field of bending test equipment, specifically a positioning device for bending tests. Background Technology

[0002] In modern industry and scientific research, materials performance testing is a crucial step. By conducting various experiments on materials, we can gain a deeper understanding of their mechanical, physical, and chemical properties, providing a basis for material selection, design, and application. The bending test, as a common method for testing the mechanical properties of materials, is widely used in the research and quality inspection of various materials, including metals, plastics, rubber, and composite materials.

[0003] The prior art discloses a bending test device for metal materials, with announcement number CN220271044U. The device includes a bending test machine, a support platform fixedly connected to the top of the bending test machine, a positioning clamp fixedly connected to the top of the support platform, and a driving component fixedly connected to the top of the bending test machine behind the support platform. A vertical rod is fixedly connected to the output end of the driving component. Three bending components are sequentially connected from top to bottom to the outside of the vertical rod. The bending components can move up and down on the outside of the vertical rod and are secured by positioning bolts. The positioning clamp on the support platform positions the sheet metal material on the working surface of the support platform. A first clamping plate and a second clamping plate cooperate to clamp the sheet metal material at the bending test location. The driving component operates by using the vertical rod to drive the bending components, causing the sheet metal material to bend at the bending test location, facilitating bending tests on sheet metal materials by the operator.

[0004] The aforementioned bending test positioning device uses a first clamping plate and a second clamping plate to clamp the sheet metal material. By operating the combined bolts and nuts, the first clamping plate and the second clamping plate can clamp the sheet metal material, so that the bending component is clamped at the bending test location of the sheet metal material. However, the above device cannot adjust the bending point during bending; the bending point can only be adjusted by sliding the metal plate. This results in poor adaptability and unsatisfactory performance during use, and improvements are needed. Utility Model Content
