Abstract

The invention relates to a drop hammer impact testing machine, and the testing machine comprises a machine platform and a vertical frame. The vertical frame is provided with a vertical guide rail, and the top of the vertical frame is provided with a lifting mechanism. The lifting mechanism drives a locking mechanism to rise and fall, and the vertical guide rail below the locking mechanism is provided with a weight block rack. The top of the weight block rack is provided with a locking body, and the weight block rack is provided with a roller. The vertical frame is provided with fixing mechanisms for fixing an elastic rope, and the bottom of the side surface, provided with the vertical guide rail, of the vertical frame is provided with a pulley mechanism, wherein the pulley mechanism comprises pulley bodies. One end of the elastic rope is connected with one fixing mechanism, and then sequentially surrounds the pulley bodies at the bottom of the side surface of the vertical guide rail, and the other end of the elastic rope is connected with the other fixing mechanism. A weight block is provided with a hooking block. The elastic rope between the pulley bodies is located at a rising path of the hooking block. The testing machine employs the elastic rope to apply energy to the weight rack, and can meet the requirements of the impact test of a bigger drop hammer. The roller on the weight rack facilitates the reduction of energy loss of weight rack testing, and enables the testing to be more stable.

Description

technical field [0001] The invention relates to testing equipment, in particular to a drop weight impact testing machine. Background technique [0002] In the material testing industry, the drop weight impact testing machine is a kind of special equipment widely used for impact testing of metal, plastic, composite materials and other samples. Existing drop weight impact testing machines usually use weights to freely fall at different heights for impact testing. This method has a small testing range and poor stability of testing accuracy. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the present invention is to provide a drop weight impact testing machine. [0004] The technical solution adopted by the present invention to solve the technical problem is: a drop weight impact testing machine, including a machine platform, a stand arranged on the machine platform, and two vertical Guide rail, the top of the stand is provided w...
