The invention discloses a stretching and pressing integrated impact test machine and belongs to the technical field of mechanical property test of materials. The integrated impact test machine comprises a stretching impact test unit, a pressure impact test unit and an impact force applying unit, wherein the stretching impact test unit is used together with the impact force applying unit to meet the requirements of a stretching impact test; the pressure impact test unit is used together with the impact force applying unit to meet the requirements of a pressure impact test. During the stretching impact test, the load output of an external hydraulic machine drives the piston rod of a hydraulic impact cylinder to quickly move downwards, an impact beam is driven to impact a stretching beam at a high speed, and then the impact load is transmitted to a test piece until the test piece is pulled apart. During the pressure impact test, the load output of the external hydraulic machine drives the piston rod of the hydraulic impact cylinder to quickly move downwards, a pressed disc is impacted by an impact hammer head at the lower end of the piston rod, and a pressure beam is driven to impact a test piece on a bottom beam until the test piece is impacted apart. According to the integrated impact test machine, the stretching and pressure impact tests of a test piece material can be performed on only a set of equipment, so that the equipment cost is effectively reduced.
