Drop hammer impact testing machine for testing non-metallic materials

Abstract

The invention discloses a drop hammer impact testing machine for testing non-metallic materials. The testing machine comprises a box body, a guide rod arranged on the side wall of the box body and a drop hammer arranged on the guide rod. An opening is formed in the bottom of the box body; a base is arranged on one side of the box body; a first connecting plate is arranged on the base; material carrying plates are arranged at the two ends of the first connecting plate respectively; a first motor for driving the first connecting plate to rotate is arranged on the base; the first motor can drive the material carrying plate to move on the first connecting plate; a first movable groove is formed in the top of the opening; a partition plate is arranged in the first movable groove; an air cylinder for driving the partition plate to move up and down is arranged on the box body. By arranging the two material carrying plates, feeding and discharging of the plates can be carried out separately, and the testing efficiency of the plates is improved.

Description

technical field [0001] The invention belongs to the technical field of testing equipment, in particular to a drop weight impact testing machine for testing non-metallic materials. Background technique [0002] Impact collision is a common mechanical phenomenon in daily life and engineering applications, and its experimental simulation is an effective research method, and the drop hammer impact testing machine is one of the important experimental equipment. The drop hammer impact testing machine is composed of a frame, a guide rail, a hammer head and a counterweight, a lifting device and a control device. The basic principle is to use the speed of free fall to achieve impact loading on the specimen, so as to study the response of materials and structures under impact loads. During the experiment, the specimen is located at the bottom of the guide rail, and the hammer head and the counterweight are located above the specimen. The hammer head and the counterweight are lifted b...

Problems solved by technology

[0003] The impact test needs to put the plates into the testing machine one by one. Due to the large number of tests, the loading and unloading of the plates takes a long time. In order to avoid the test plates from breaking and splashing, the drop weight test is generally placed in a closed space. The loading and unloading of the board causes more inconvenience
