Horizontal extruder core rod supporting device

Abstract

The invention discloses a horizontal extruder core rod supporting device. The device comprises a mounting base, a driving mechanism and a supporting mechanism; the mounting base is arranged on a baserail of a horizontal extruder, and is driven by the driving mechanism to move in the axial direction of a horizontal extruder core rod; the supporting mechanism comprises a lifting base, a mounting platform, a first roller and a second roller; the mounting platform is slidingly matched on the mounting base, and is driven by the lifting device to act in the height direction, and the position can belocked; the first roller and the second roller are arranged on the mounting platform, are positioned under the horizontal extruder core rod, and are symmetrically distributed; and axis extension lines of the first roller and the second roller are intersected to form a V shape. The device is simple in structure and convenient to use, and can effectively prevent downward bending deformation of thehorizontal extruder core rod to guarantee the rigidity and the service life of the horizontal extruder core rod.

Description

technical field [0001] The invention relates to the field of mechanical engineering, in particular to a supporting device for a horizontal extrusion mandrel. Background technique [0002] The horizontal extruder is to turn the vertical molding machine down into a horizontal type, and add a blanking chamber and a pressing chamber. A molding nozzle is installed in front of the molding chamber, and the paste is pressed and formed through the molding nozzle. [0003] The mandrel matched with the horizontal extruder, especially for the large-stroke horizontal extruder, due to the long length of the mandrel, is bent downward under the action of gravity, resulting in The medium rigidity decreases, and after long-term operation, the degree of bending and deformation of the mandrel increases, which not only affects the quality of the extruded workpiece, but also directly leads to the scrapping of the supporting mandrel. Contents of the invention [0004] The object of the present ...

[0003] The mandrel matched with the horizontal extruder, especially for the large-stroke horizontal extruder, due to the long length of the mandrel, is bent downward under the action of gravity, resulting in The medium rigidity decreases. After long-term operation, the degree of bending and deformation of the mandrel increases, which not only affects the quality of the extruded workpiece, but also directly leads to the scrapping of the supporting mandrel.
