The invention discloses a steel plate bending
machine. The steel plate bending
machine comprises a bottom plate, a
workbench, a transmission device and an
impact hammer. The
workbench and the transmission device are fixed to the bottom plate. The
workbench is provided with a groove. The bottom face of the groove is in an arc shape. A
thermal infrared human body inductor is embedded in the side face of the groove. The
impact hammer is fixedly connected to the transmission device. The
impact hammer is arranged above the groove of the workbench. The
impact hammer comprises a hammer head, a hammer
tail mass block, a hammer plate, a hammer rod, an upper spring and a lower spring. The hammer head is welded to the bottom end of the hammer rod. The bottom face of the hammer head and the bottom face of the groove are matched. The hammer rod is sleeved with the lower spring, the hammer plate, the upper spring and the hammer
tail mass block from bottom to top in sequence. A lock nut is arranged at the top end of the hammer rod. By means of the manner, the reactive force of the
impact hammer can be buffered, the service life of the transmission device can be prolonged, and the maintaining cost of the steel plate bending
machine is reduced; and personal safety of operators can be guaranteed, and accidents are avoided.
