Abstract

Oval molding machine, characterized by being constituted by a plate of conventional dimension, in which by means of a suitable tool a template of oval or elliptical shape is rowed, with whose rotation there is movement of advance and return to a lever arm which it also has the mission to move the motor that carries a cutter closer or farther away, acting on the frame following the line of its curvature. The assembly of the motor and the milling cutter is capable of approaching or separating, being distant the milling cutter that acts on the frame following the line of its curvature. The assembly of the motor and the milling cutter is capable of approaching or separating, leaving the milling cutter of the frame a conventional space, which at the moment of starting the operation of the machine, is covered by putting the cutter in contact with the frame by means of the action of a pneumatic piston. Another motor of analogous disposition to the previous located in the suitable place, transmits its movement by means of pulleys, having in the opposite end of the axis, mounted a strawberry forming a set that goes mounted in a charriot or sliding female that slides on another slide male of greater length, being able to carry out said movement by means of a cam that drives a lever arm that gives the movement of vaiven to the female slide, since it goes in solidarity with it. Said lever is in continuous contact with the cam thanks to the action of a spring capable of being tensioned at will by means of a suitable tensioning screw. All this set is mounted on a transmission box that approaches the frame by the action of a steering wheel, and a movement along a threaded shaft, dragging the expressed cam that slides on an axis, which has mounted a few keys which serve for such cam to perform a turning movement while making another translation movement. The axis by which the cam slides, performs its movement by means of a pulley which in turn receives it from another that is mounted on the carrier plate of the template. The first of the two sets is the one that forms the lateral molding of the dizziness, forming the frontal molding, simultaneously, by the action of the second set.
