A kind of flexible miniature ring experimental rolling mill

Abstract

A miniature flexible ring piece test press mainly comprises a core roller, a core roller bearing seat, a bevel gear, a planetary reducer, a three-phase asynchronous motor, core roller hydraulic cylinders, a hydraulic cylinder bottom plate, a main roller, a main roller bearing seat, a main roller frame, main roller slide rails, a roller-embracing hydraulic cylinder, a roller-embracing four-bar link, roller-embracing supporting frames, embracing rollers, sliding table modules, bulb connecting heads, a conical roller connecting rod, a conical roller platform, roller replacement slide rails, conical roller slide rails, a conical roller frame, a roller replacement support, a motor supporting frame, a motor, roller replacement slide rails, slide rails and a core roller hydraulic cylinder lantern ring. The miniature flexible ring piece test press has the advantages that vertical and horizontal movement of a conical roller is achieved through a parallel mechanism, so that equipment tonnage and power are decreased, the requirements on the motor are lowered, and the requirements on experimental equipment miniaturization are guaranteed; the conical roller frame is mounted on the slide rails and is capable of adapting to large-range change of the diameters of rolled pieces, so that flexible manufacture is achieved; the embracing rollers are driven by the four-bar link, so that action executing distance is shortened, space dimensions are reduced, and the number of hydraulic cylinders is decreased.

Description

technical field [0001] The invention belongs to the technical field of metal material forging machinery, in particular to disclosing a flexible miniature ring experimental rolling mill. Background technique [0002] The tapered roller system of the traditional radial and axial ring rolling machine is completed by a series mechanism, which is bloated, bulky, inefficient, and expensive. In addition, the diameter range of the ring parts that can be rolled is limited and not flexible; the traditional radial and axial ring rolling machine The roll holding system is a linkage mechanism driven by a hydraulic cylinder, which is huge and does not meet the miniaturization requirements of the experimental rolling mill. The structure of the traditional ring rolling mill is not suitable for the characteristics of miniaturization, flexibility and product flexibility of the experimental rolling mill. Contents of the invention [0003] The purpose of the present invention is to provide a...

[0002] The tapered roller system of the traditional radial and axial ring rolling machine is completed by a series mechanism, which is bloated, bulky, inefficient, and expensive. In addition, the diameter range of the ring parts that can be rolled is limited and not flexible; the traditional radial and axial ring rolling machine The roll holding system is a connecting rod mechanism driven by a hydraulic cylinder. The mechanism is huge and does not meet the needs of miniaturization of the experimental rolling mill.

The structure of the traditional ring rolling machine is not suitable for the miniaturization, flexibility and product flexibility of the experimental rolling mill
