Numerical-control roller bending device used for step guide rail bending, molding and processing

Abstract

The invention discloses a numerical-control roller bending device used for step guide rail bending, molding and processing. The numerical-control roller bending device used for step guide rail bendingcomprises a main body, wherein a spacing regulating mechanism is arranged inside the main body; two fixed mold mechanisms are arranged at the upper end of the spacing regulating mechanism; a movablemold mechanism is arranged on the upper surface of the main body; and one end of the upper surface of the main body is equipped with a pressure mechanism. The numerical-control roller bending device disclosed by the invention has the beneficial effects that: spacing regulation between the two fixed mold mechanisms is more synchronous by the spacing regulating mechanism via a two-way threaded rod,and manual operation is not needed; step guide rails of different bending amplitudes are rolled by regulating different spacings, and contact points between fixed molds of the two fixed mold mechanisms and the step guide rails change, so that a slide block can be effectively fixed through a slide plate and a limiting slot without sliding; and a third motor is used for regulating, so that a strokeof a hydraulic rod can be changed to change movement amount of the movable molds to change depth of roller-pressing, and thus, roller-pressing radian of the step guide rails can be freely regulated.

Description

Technical field

[0001] The invention relates to a guide rail bending device, in particular to a numerical control roller bending device used for bending and forming of ladder road guide rails, and belongs to the technical field of machinery.Background technique

[0002] The escalator is a combination of a chain conveyor with a special structure and two belt conveyors with a special structure, with a circular movement ladder to move up or down between different floors of the building Stationary electric drive equipment for inclined transportation of passengers. A continuous conveying machine that carries people up and down.

[0003] In recent years, with the continuous increase of urbanization, the rapid development of urban transportation, urban transportation construction, and a large number of subway transportation projects have greatly promoted the escalator industry. The traditional process of stairway guide rails is completed by drawing and bending. Although the process is simple, the cr...
