Abstract
The utility model relates to an oil cylinder driven by a pressure machine, in particular to a combined plunger oil cylinder, which is applicable to various hydraulic devices with small working table tops and belongs to the technical field of machining technology. The combined plunger oil cylinder comprises a plunger cylinder, a plunger rod arranged in the plunger cylinder, a piston cylinder is fixed at the end of the plunger cylinder by screws and is internally provided with a piston rod that is in threaded connection with the plunger rod, the plunger cylinder is driven by the piston cylinder so as to realize control on the speed of the plunger cylinder through the piston cylinder. The combined plunger oil cylinder is applicable to various large-tonnage hydraulic devices with small working table tops, and realize control on the speed of the pressure machine during quickly descending process, has a smart structure, and is easy to replace a sealing ring, simple to install and convenient to maintain.
Description
Technical field
The utility model relates to a kind of press machine driving oil cylinder, is specifically related to a kind of combined plunger oil cylinder, is applicable to all kinds of subtable face hydraulic equipments, belongs to the Machining Technology field.
Background technique
At present, in the metal forming machinery industry, for the processing of the little table top hydraulic equipment of large-tonnage, as adopt piston type cylinder must set up the backhaul driving oil cylinder, satisfying plunger case backhaul needs, because of the equipment work table top little, the layout of kicker cylinder is just relatively more difficult, does not have good solution so far.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art part, a kind of combined plunger oil cylinder is provided, this oil cylinder includes plunger case, plunger case inner prop stopper rod, there is a piston cylinder plunger case end by screw, and piston rod is arranged in the piston cylinder, and piston rod and plunger rod are by being threaded, utilize piston cylinder drive post plug cylinder, realization plunger case speed is controlled by piston cylinder.This combined plunger oil cylinder is applicable to that all kinds of table tops are little, the large-tonnage hydraulic equipment, and realized quick speed-controllable when descending of press, and the combined plunger cylinder structure is ingenious, and seal ring is easily changed, and installs simple, easy to maintenance.
The utility model is realized with following technological scheme: a kind of combined plunger oil cylinder is characterized in that: this oil cylinder includes plunger case, plunger case inner prop stopper rod, and there is a piston cylinder plunger case end by screw, and piston rod is arranged in the piston cylinder.
Described piston rod is connected with plunger rod by screw thread.
In the described plunger case guide sleeve is arranged, between guide sleeve and the plunger case sealing gasket is arranged, guide sleeve by flange and screw on plunger cylinder.
The utility model has the advantages that: this oil cylinder includes plunger case, plunger case inner prop stopper rod, there is a piston cylinder plunger case end by screw, piston rod is arranged in the piston cylinder, piston rod and plunger rod are by being threaded, utilize piston cylinder drive post plug cylinder, realization plunger case speed is controlled by piston cylinder.This combined plunger oil cylinder is applicable to that all kinds of table tops are little, the large-tonnage hydraulic equipment, and realized quick speed-controllable when descending of press, and the combined plunger cylinder structure is ingenious, and seal ring is easily changed, and installs simple, easy to maintenance.
