Special hydraulic machine for stamping end socket

Abstract

The special hydraulic machine comprises a supporting base, a control host is installed on the right portion of the upper end of the supporting base, a movable workbench is installed in the middle of the upper end of the supporting base, four stand columns are installed at the upper end of the movable workbench, and a guide sleeve is jointly installed on the outer surfaces of the four stand columns; the upper ends of the four stand columns are jointly provided with a lower beam, the upper end of the lower beam is provided with two jacking columns, the upper ends of the two jacking columns are provided with a stretching sliding block, the upper end of the stretching sliding block is provided with three stretching oil cylinders, and the upper ends of the three stretching oil cylinders are jointly provided with an upper beam. According to the hydraulic machine special for end socket stamping, the guide sleeves are installed at the four corners of the stretching sliding block, the guide precision of the sliding block is guaranteed, the unbalance loading resisting capacity is high, rigidity is good, precision retentivity is good, the stand columns and the guide sleeves adopt automatic program control thin oil lubricating devices, the friction mechanism is improved, friction resistance is reduced, and the stand columns are prevented from being scratched and strained.

Description

technical field [0001] The invention relates to the technical field of head stamping, in particular to a special hydraulic press for head stamping. Background technique [0002] The idle stroke and return stroke of the head hydraulic press can be high-speed, and the speed of the working stroke can be adjusted according to the needs. When actively switching from the working stroke to the return stroke, it can be controlled by the stroke direction or the effect force of the hydraulic press, and can also be controlled by the preset effect. The force is switched after a predetermined moment is applied. The operation forms include active stroke, single stroke and inching. The hydraulic press can be equipped with automatic feeding of blanks, automatic transmission of workpieces between stations, and automatic unloading of forgings. The number of ejectors in the workbench can be regarded as Single-station or multi-station to equip. The filling valve is used on large and medium-si...

Problems solved by technology

When the stretching oil cylinder on the existing head hydraulic machine drives the stretching slider to work on the column for a long time, the column will inevitably be scratched and strained, and the precision of the stretching slider after sliding for a long time is also difficult. Guarantee, at the same time, after the stretching cylinder is used for a period of time, the cylinder port is not only prone to oil leakage, but also needs to be regularly repaired and replaced for the seal
