Description

TECHNICAL FIELD

[0002] The tensile testing device is mainly used for testing the tensile strength, tearing strength, peeling strength, adhesive strength and other resistance properties of various materials. After a copper roll is wound into a shell, a base is welded on the wound copper shell.

The clamping jaws on the lifting block clamp one end of the base of the copper shell, and the clamping jaws on the main body clamp the other end of the base of the copper shell. Then the cylinder is started, and the piston rod of the cylinder drives the lifting block to move, so that the clamping jaws on the lifting block drive the base to move.
