An automated installation for punching and cleaning converter tuyeres for use in non-ferrous pyrometallurgy. The invention employs a travel unit fixed either to the converter housing permits movement of the punching unit relative to the tuyeres and, consequently, piercing of tuyeres at the converter. The unit consists of a punching rod slidable along the axis for introducing the punching end-piece of the punching rod into the tuyeres and a car securing the opposite end of the punching rod. The car resting on the rail is moved along by a driving unit. The drive mechanism of the travel unit has at least one power cylinder located transversally with respect to the rail, whereas on the extended end of the piston rod of this cylinder is a carriage with at least one pair of pull rods is mounted being coupled with the rod in an articulated way. Still another embodiment of the invention consists in an application of only one pair of pull rods mounted on the both sides of the piston rod of the above mentioned cylinder in an articulated way slidable in a carriage in a plane perpendicular to the axis of the above mentioned power cylinder. One of pull rods is connected in an articulated way with the rail on the side of the above mentioned power cylinder opposite to the punching unit, while the other pull rod with is connected with the punching unit accommodating the working tool.
An automated apparatus for punching and cleaning the converter tuyeres to be used particularly in non-ferrous pyrometallurgy, said apparatus being provided with a travel unit mounted to a converter housing enabling displacement of a punching unit with respect to the tuyeres and punching of the tuyeres at converter means, said punching unit employing an axially shiftable punching rod mounted in a supporting guide for introducing the working end of the rod into the tuyeres, the opposite end of the punching rod mounted, being in a car, said car being mounted on a rail and being movable along said rail by means of a driving unit, said driving unit including:
An automated assembly for punching and cleaning of converter tuyeres for use primarily in non-ferrous pyrometallurgy provided with travel means fixed to a converter housing or the like, said travel unit rendering possible a displacement of the said punching assembly with respect to the tuyeres and punching of said tuyeres at a converter means, said punching assembly containing an axially slidable punching rod mounted in a supporting guide for introducing the end of the rod into the tuyere, the opposite end of this punching rod being fastened to a car, said car resting on a rail and moved along said rail by means of a driving unit, a driving mechanism of the punching assembly being provided with at least one power cylinder situated transversely with respect to the axis of the rail, whereby on the extended end of the piston rod of the power cylinder there being mounted a carriage, wherein on the both sides relative to the axis of the piston rod of the above mentioned power cylinder there being mounted at least one pair of pull rods adapted to move in an articulated way, said pull rods being slidable in said carriage in a plane perpendicular to the axis of the above mentioned power cylinder, and one of the pull rods being connected in an articulated way with a rail on the side of the above mentioned power cylinder opposite to the punching assembly and the second pull rod being coupled with a car of the punching assembly wherein said punching rod being mounted.
