The utility model relates a transmitting structure for a high-rigidity door-type double-point press machine and belongs to the technical field of a press machine. The transmitting structure for a high-rigidity door-type double-point press machine comprises a body, a bent axle and a slide block. The bent axle is supported in the installation hole of the body in a rotating mode. A flywheel is placed at the end of the axle. Eccentric axle necks are placed on the bent axle in a bilateral symmetry mode. The transmitting structure for the high-rigidity door-type double-point press machine is characterized in that the slide block is provided with a connecting end which is directly connected with the eccentric axle necks of the bent axle. The bent axle directly and horizontally penetrates through the connecting end of the slide block and is connected with the slide block in a rotating mode through eccentric rocking beams which are placed on periphery of the eccentric axle necks in a sleeved mode. The slide block is connected with the body in a sliding mode through a longitudinal slide block guide rail. The transmitting structure for the high-rigidity door-type double-point press machine leaves out a link mechanism, so that main transmitting system of the press machine is compact in structure, low in gravity center, balanceable and reliable in transmission, reduces overall height of the body, reduces the gravity of the body correspondingly, strengthens rigidity and shock resistance of the body and correspondingly reduces vibration noise of the whole press machine.
