AI Technical Summary
Existing equipment for preparing adhesive tensile shear strength test specimens has low production efficiency and quality stability, making it difficult to meet the industrial sector's demand for efficient and stable testing.
A sample preparation device for tensile shear strength testing of adhesives based on multi-dimensional control is provided, including a sample positioning mechanism, an adhesive layer thickness control component, and a sample pressurization component. The device ensures that the bonding length and width error are within ±0.5 mm through mechanical limiting, and the adhesive layer thickness is continuously adjustable from 0.05 mm to 3.0 mm, which is suitable for sample preparation of different standards.
It enables efficient and high-quality preparation of test specimens for standards such as GB/T 7124, GJB 444, and GJB 1709. It can prepare a large number of specimens at a time, with a high specimen pass rate and small deviation in adhesive layer thickness, and can meet the testing needs of different bonding areas.
