Fastener Bolt Tensile Testing Machine

The fastener bolt tensile testing machine belongs to the field of aviation testing technology, specifically proposing a connection device for fastener bolt tensile testing. This device includes an upper connecting screw, an upper protective cover, an upper force-bearing seat, a lower protective cover, a lower force-bearing seat, a lower connecting screw, an upper load-bearing component, an upper positioning bolt, a lower positioning bolt, and a lower load-bearing component. The upper connecting screw is threadedly connected to the upper force-bearing seat. The upper protective cover is equipped with an upper sliding groove, and the lower protective cover is equipped with a lower sliding groove. The upper protective cover is fixed to the upper force-bearing seat, and the lower protective cover is fixed to the lower force-bearing seat. The lower connecting screw is threadedly connected to the lower force-bearing seat. The upper connecting screw is connected to the upper grip of the testing machine, and the lower connecting screw is connected to the lower grip of the testing machine. This device prevents the risk of test specimens splattering and causing injury during bolt fracture, making it particularly suitable for testing larger-sized bolt specimens. It ensures better coordination between the specimen head and the load-bearing component during testing, significantly improving the accuracy and stability of test data.

Main functions of the fastener bolt tensile testing machine:

It can perform mechanical property testing and analysis on various metals, non-metals, and composite materials, widely used in industries such as aerospace, petrochemicals, mechanical manufacturing, plastics and rubber, ceramic building materials, metal materials, and construction engineering.

It can conduct tensile, compression, bending, peeling, shear, tearing, puncture, burst, and various high and low-temperature tests according to standards such as GB, ASTM, JIS, and DIN. It can detect parameters such as yield strength, tensile (bending, compression) strength, elongation, non-proportional strength, and elastic modulus of specimens.
