Abstract

The invention relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder of a thrust floating buffer industrial furnace. The hydraulic oil cylinder comprises a cylinder body vertically mounted, wherein the bottom end of the cylinder body is a cylinder bottom; a piston is arranged in the cylinder body, and is fixedly connected with a piston rod; the piston rod is coated with a cylinder cover; the cylinder cover is fixedly mounted at the upper end of the cylinder body; the inner diameter of the piston rod is smaller than the inner diameter of the cylinder body; the piston divides the cylinder body into a rod cavity and a rodless cavity; a floating buffer piston component for limiting the piston to upwards move is arranged in the rod cavity, and coats the piston rod; and an outer ring of the floating buffer piston component is tightly connected with the inner wall of the cylinder body. As the hydraulic oil cylinder of the thrust floating buffer industrial furnace is additionally provided with one set of floating buffer piston component in the rod cavity, when the descending of the oil cylinder is suddenly stopped, the pressure ascending speed of the rodless cavity is slowed down, and soft landing of a furnace body and molten steel is realized.

Description

technical field [0001] The invention relates to the technical field of hydraulic oil cylinders, in particular to a thrust floating buffer industrial furnace hydraulic oil cylinder. Background technique [0002] The hydraulic cylinder is the actuator in the hydraulic system. It is an energy conversion device that converts hydraulic energy into mechanical energy for reciprocating linear motion. It is generally composed of a cylinder body, a piston, a piston rod, and a cylinder head. The oil cylinders of industrial furnaces are installed vertically, and the rodless cavity is always stressed, and the load mass is relatively large, so the impact load will rise rapidly when the stop is stopped. Excessive impact will cause damage to the cylinder seal, cylinder block, hydraulic system and the entire mechanical structure . Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to solve the technical problem of damage to the oil ...
