Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology for copper nuts in plastic parts, specifically a tooling for testing the tensile strength of copper nuts in plastic parts. Background Technology

[0002] People have increasingly higher requirements for the maximum load that plastic materials can withstand. To test the maximum load that a plastic product can withstand, we need to test the maximum tensile force that the product can withstand without the copper nut falling off.

[0003] A tensile testing machine for plastic production, disclosed in publication number CN215953191U, includes a protective box, a clamping structure, and a tensile sensor. A base is slidably mounted on the inner bottom wall of the protective box. Two sets of symmetrically arranged slides are provided on the top of the base. A slider is slidably mounted inside each of the two sets of slides. The clamping structure is mounted on the top of each slider. The clamping structure includes a lower base plate, a support frame, a pressure plate, fixing bolts, and positioning nuts. The lower base plate is mounted on the top of the slider, and the support frame is mounted on the top of the lower base plate. A fixing bolt is screwed into the threaded hole, and one end of the fixing bolt is connected to the pressure plate. The pressure plate, adjustable up and down by the fixing bolt, can clamp and test the tensile force of plastic products of different heights. Simultaneously, the protective box provides protection during the tensile testing process, preventing damage to the operator and the tensile testing machine itself.

[0004] Existing technologies can test plastic products, but cannot test the tensile strength of nuts on plastic products. Therefore, we propose a tooling for testing the tensile strength of copper nuts on plastic parts. Utility Model Content
