The utility model discloses a warm powder high-speed pressing and forming device based on gravitational potential energy. A hammer rope of the device is connected with a motor through a pulley which is arranged right above a guide cylinder, and keeps free and vertical motion in the guide cylinder; velometers are symmetrically arranged on both sides of a side template; a heating coil is directly sleeved on a mould; a pressure sensor contacts with a lower plunger, and is connected with a data acquisition card; and the data acquisition card is connected with a computer through a USB interface. The utility model directly generates shockwave graphics on a computer through software, and the maximum impact and powder application time can be directly read from the graphics; and the device has the advantages of simple structure, convenient use, reliability, practicality and relatively lower price, and is particularly applicable to universities and scientific research units.
