Compressive strength testing machine for metal shell

The utility model belongs to the technical field of metal strength testing, particularly relates to a compressive strength testing machine for a metal shell, and aims to solve the problems that the existing compressive strength testing machine is not provided with a protection device, part of metal is exploded after being subjected to certain pressure, potential safety hazards are caused, to-be-tested metal is not limited, only the to-be-tested metal with the same thickness size can be tested, and the application range is small. According to the scheme, the device comprises a base, a test board is fixedly connected to the top of the base, a mounting cavity is formed in the top of the test board, and a side plate is fixedly connected to one side of the test board. According to the utility model, part of metal such as bronze can be directly exploded to cause potential safety hazards after being subjected to a certain pressure effect, such safety accidents can be effectively avoided through the arrangement of th
