Equipment used for rolling cones

Abstract

The invention discloses equipment used for rolling cones. A cone rolling tool is mounted on the inner side of an overturn rack or the inner side of a fixed rack and comprises a bracket and two sets of friction limit devices structurally arranged in axial symmetry are arranged on the bracket; each friction limit device comprises a support, a pin shaft, a hinge fulcrum shaft and a roll sleeve; the upper portion of the hinge fulcrum shaft is provided with a support shaft, the lower portion of the hinge fulcrum shaft is provided with a positioning pull arm, and the middle portion of the hinge fulcrum shaft is provided with a mounting hole; the positioning pull arm is fixedly connected with the support through a pin, the hinge fulcrum shaft is rotatably connected on the pin shaft, two ends of the pin shaft are respectively fixed on the support, the roll sleeve is fixed on the support shaft, and when a workpiece is rolled on a plate rolling machine, the outer cylindrical surface of the roll sleeve is closely attached to the end face of a small end of each cone to be rolled. The equipment has the advantages of simplicity in operation, high working efficiency and high precision in rolling the cones; the equipment is especially suitable for rolling of the thin-walled cones with large-diameter taper angles larger than 15 degrees.

Description

technical field [0001] The invention relates to a device for rolling a cone, in particular to a device for rolling a cone. Background technique [0002] At present, the production of wind turbine towers requires a special four-roll plate rolling machine, which is expensive. In the case of the existing three-roll plate rolling machine, it is very difficult to roll the fan tower. The concentricity of the big and small openings of the cylinder and the amount of misalignment are relatively large. Due to the thin wall thickness, a crane is required to lift one end during the rolling process, and the crane is occupied for a long time, and due to its own weight, the roundness tolerance after rolling is relatively large, which increases the difficulty of circle calibration. Contents of the invention [0003] In order to solve the technical problems in the known technology, the invention provides a device for rolling cones. [0004] The technical solution adopted by the present ...
