Problems solved by technology

[0003] In the traditional drop hammer impact testing machine, the punch at the bottom of the drop hammer does not have a sharp part, so it cannot pierce the fabric, and it is not suitable for testing the knife-puncture resistance of the fabric. Therefore, it is necessary to test the punch part of the drop hammer Modified so that it can be used for the detection of knife-puncture resistance of fabrics

Abstract

The invention discloses a punch for fabric puncture test, which is connected with a drop hammer of a drop hammer type impact testing machine, a rod body is arranged at the bottom end of the drop hammer, and the punch comprises a connecting base and a cutter. The connecting base is provided with a first end and a second end which are opposite in the first direction, the first end is provided with a mounting hole for mounting the rod body, and the second end is provided with a mounting groove. The cutter is provided with a cutter handle end and a puncturing end in the first direction, the cutter handle end is installed in the installation groove, and the puncturing end is provided with a sharp part. A first screw hole communicated with the mounting hole is formed in the side wall of the connecting base in the second direction, and a first screw is arranged in the first screw hole. A second screw hole communicated with the mounting groove is formed in the side wall of the connecting base in the second direction, and a second screw is arranged in the second screw hole. By means of the punch, the drop hammer type impact testing machine can be suitable for tool puncture resistance detection of fabric, and the limitation that in the prior art, a drop hammer type impact testing machine cannot conduct a puncture test is eliminated.

Description

technical field [0001] The invention relates to the field of puncture performance testing of textile materials and composite materials, in particular to a punch for fabric puncture testing. Background technique [0002] The traditional drop weight impact testing machine mainly includes a drop weight lifting drive assembly, a drop weight is provided at the bottom of the drop weight lift drive assembly, and a punch is provided at the bottom of the drop weight. Driven by the drop hammer lifting drive assembly, the drop hammer drives the punch to move downward to impact the object to be tested. The traditional drop weight impact testing machine is used to perform impact tests on plastic pipes, plates and products to evaluate the impact resistance of these materials. [0003] In the traditional drop hammer impact testing machine, the punch at the bottom of the drop hammer does not have a sharp part, so it cannot pierce the fabric, and it is not suitable for testing the knife-pun...
