Abstract
Abstract There is disclosed an apparatus for the electric spark deposition of metals. The apparatus comprises a logic block, the input of which is connected to the output of a following system, a motor for horizontal motion in the x-direction and a motor for horizontal motion in the y-direction, such motors being connected by their inputs to a command unit and by their outputs to the movable table of the deposition apparatus; the motor for horizontal motion in the x-direction, the motor for horizontal motion in the y-direction and the motor for vertical motion are connected, respectively, to one of the outputs of the logic block. The advantages of the apparatus of the present invention are that it is provided with an electronic control of the motors for the horizontal and vertical motions of the depositing electrode-anode, which permits the total automation of the process of electric spark deposition onto workpieces, as well as the regulation of the inclination of the depositing head with respect to the vertical plane. Moreover, this device permits the maintenance of a working gap between the forming surface of the depositing electrode-anode and the deposited material; this makes possible deposition in a horizontal plane along coordinate axes ±x and ±y and depositing onto internal and inclined surfaces.
