Abstract
The invention provides a structure of a hydraulic machine material ejection mechanism and belongs to the technical field of hydraulic machines. The structure of the hydraulic machine material ejection mechanism is characterized in that a hydraulic cushion is arranged and fixed to the space between a machine tool base and a machine tool workbench, a locating shaft is arranged and fixed to the center of the hydraulic cushion, a locating disc is fixed to the upper plane of a movable cylinder of the hydraulic cushion through a locating shaft, blind holes distributed in the circumferential direction are formed in the upper plane of the locating disc, corresponding through holes are formed in the machine tool workbench located over the blind holes, an ejector rod is arranged in each through hole, and the bottom of each ejector rod is arranged in the corresponding blind hole in the locating disc under the ejector rod. The structure of the hydraulic machine material ejection mechanism has the advantages that the ejector rods are not prone to abrasion and breakage and the shortages of a device fault and a product quality accident which are caused by abrasion and breakage of the ejector rods are overcome.
Description
Technical field
The present invention relates to hydraulic press, be specifically related to the structure of hydraulic press material jacking mechanism, belong to hydraulic press technical field.
Background technology
Hydraulic press material jacking mechanism generally comprises hydraulic die cushion, push rod, described hydraulic die cushion is arranged in the workbench and the space between base of hydraulic press, on the workbench that described hydraulic die cushion top aligns, at circumferencial direction, some through holes are set, an identical push rod is set in the through hole described in each, in the structure of existing this class hydraulic press material jacking mechanism, the bottom of push rod freely contacts with the movable cylinder of hydraulic die cushion, because push rod is in the process of liftout, its suffered power can not be completely consistent with the axis of push rod, so, the easy unstability of push rod, cause suffered stroke resistance to increase, not only easily wearing and tearing, toward contact, easily fracture, and cause thus equipment fault and product quality accident, 201120125368.2 of China Patent No. are called the disclosed technical scheme of stretch-formed lifting hydraulic cushion of hydraulic press, attempt to solve above-mentioned existing problem, but this technical scheme only arranges some close backing plates mutually in the bottom of push rod, because the bottom of push rod is still in free state, so, bottom likely causes off-axis position, bottom under the effect of component, still can cause suffered stroke resistance to increase, not only easily wearing and tearing, toward contact, easily fracture, and cause thus equipment fault and product quality accident.
Summary of the invention
The object of the invention is to: for the existing above-mentioned defect of structure of existing hydraulic press material jacking mechanism, the invention provides a kind of structure of hydraulic press material jacking mechanism of new structure, overcome the existing above-mentioned defect of structure of existing hydraulic press material jacking mechanism.
The structure of a kind of hydraulic press material jacking mechanism of the present invention, it is by lathe base, platen, push rod, positioning disk, locating shaft, hydraulic die cushion forms, it is characterized in that: in the space between lathe base and platen, arrange and fix a hydraulic die cushion, described hydraulic die cushion centre arranges fixes a locating shaft, positioning disk of plane layout on the movable cylinder of hydraulic die cushion, locating shaft combines through positioning disk interstitial hole and positioning disk, on described positioning disk, plane is shaped with the blind hole of circumference branch, platen directly over blind hole is shaped with corresponding through hole, a push rod is set in each through hole, the bottom of each push rod is arranged in the blind hole on the positioning disk under it.
Beneficial effect: the present invention is owing to adopting after said method, the bottom of push rod is subject to compulsory location, can may be not consistent with the axis of push rod because of the power being subject to, and cause the easy unstability of push rod, cause suffered stroke resistance to increase, easily wearing and tearing, easily fracture, and cause thus the defect of equipment fault and product quality accident.
