Description

Special hydraulic press for end socket stamping

Technical Field

The invention relates to the technical field of end socket punching, in particular to a special hydraulic press for end socket punching.

Background

The idle stroke and the return stroke of the end socket hydraulic machine can be high-speed, the speed of the operation stroke can be regulated according to needs, when the operation stroke is actively switched to the return stroke, the operation stroke can be controlled by using the stroke direction or the effect force of the hydraulic machine, and the operation stroke can be switched after a preset effect force is applied for a preset moment. The operation modes comprise an active stroke, a single stroke and inching, the hydraulic press can be provided with the active feeding of a blank, the active transmission of a workpiece among stations and the active discharging organization of a forge piece, and the number of ejectors in the operation table can be regarded as being provided with single stations or multiple stations. The liquid filling valve is used on large and medium hydraulic machines, the oil cylinders of the large and medium hydraulic machines are large, the liquid filling valve is supplied by the oil pump, the descending speed is too slow, the output power is influenced, an upper oil tank is arranged on the top of the hydraulic machine, the liquid filling valve is arranged between the upper oil tank and the upper cavity of the oil cylinder, when the piston is lowered, the liquid filling valve is turned over, the oil in the upper oil tank is directly supplied to the upper cavity of the oil cylinder, and when the oil is pressurized, the liquid filling valve is closed and is pressurized by the oil pump. When the piston rises, the liquid filling valve is turned over, and the oil in the upper cavity of the oil cylinder returns to the upper oil tank.

The end socket hydraulic press can also be used for correcting, press-fitting, packing, briquetting, pressing plates and the like, can also be used for the pressing process of shaft parts, the calibration, buckling and press-fitting process of profiles, the bending, disputing, sizing, impressing, sleeve type, stretching and the pressing process of plastic materials of plate parts, such as the operations of stamping, bending, flanging and thin stretching and the like, can also be used for the operations of correcting, press-fitting and press-forming of plastic products and powder products, and is also called as a universal hydraulic press due to the wide application range. When a stretching oil cylinder on the existing end socket hydraulic machine drives a stretching sliding block to work on an upright column for a long time, the upright column is inevitably scratched by a scratching machine, the precision of the stretching sliding block is difficult to guarantee after the stretching sliding block slides for a long time, and simultaneously, after the stretching oil cylinder is used for a period of time, a cylinder opening of the stretching oil cylinder is easy to leak oil and a sealing element also needs to be periodically overhauled and replaced. Therefore, we propose a special hydraulic press for end socket stamping.
