The utility model discloses structural connection is simple, and occupation space is little, and lever punching press utilizes lever principle to consume littleer than the direct punching, and the stamping workpiece atress is balanced, and the noise is low and the vibration is little, and stamping pressure is big.
Description
Technical Field
The utility model relates to a press stamping device especially relates to a lever is stretched and is folded device.
Background
As a press machine disclosed in chinese patent application No.: CN99230062.2, the fuselage mainly sets up piston cylinder, lever, connecting rod, slider, through the control to the hydro-cylinder, realizes the adjustment to suppression power, slider working stroke, speed, reaches three kinds of technological actions of drawing, suppression, blanking, can not produce the overload phenomenon, can realize the pressurize of each step in the pressing process and the time delay requirement, and the positioning accuracy of slider bottom dead center. However, the press adopts a single lever mode to drive the slide block to press downwards, so that the problems of large power consumption and small pressing force of the slide block of the press are caused.
Disclosure of Invention
An object of the utility model is to provide a lever is stretched and is folded device.
The utility model provides a technical scheme that above-mentioned technical problem adopted is:
a lever stretching and stacking device comprises an upper shaft, a middle shaft, a lower shaft, an upper bar plate and a lower bar plate, wherein the upper bar plate and the lower bar plate are connected through the middle shaft, the upper end of the upper bar plate is connected with a top plate through the upper shaft, the lower end of the lower bar plate is connected with an upper die of die forging equipment through the lower shaft, and the middle shaft is connected with a power device.
Furthermore, a lubricating structure is arranged at the connecting end of the upper and lower lever plates, a groove is arranged in the upper and lower lever plates and is connected with a pipeline of the lubricating structure, and the groove is also contacted with the shaft. The friction between the shaft and the upper and lower lever plates is reduced in the punching process through lubricating oil, and the heat generated by the shaft is taken away through circulating lubricating oil.
Furthermore, the power device is a hydraulic device, and the hydraulic device is connected with two ends of the middle shaft through two pull rods.
Furthermore, the power device is a mechanical device, the mechanical device is a motor which drives a gear, the gear is connected with the middle part of the middle shaft through a connecting rod, and two ends of the middle shaft are respectively connected with the bearings.
Furthermore, copper sleeves are additionally arranged between the upper plate, the lower plate and the middle shaft. The copper bush is contacted with the shaft, so that the service life of the upper plate and the lower plate is prolonged.
Furthermore, the copper bush between the upper plate and the lower plate is combined into a circular ring, and an oil groove is arranged on the inner wall of the copper bush. The utility model has the advantages that:
the utility model discloses structural connection is simple, and occupation space is little, and lever punching press utilizes lever principle to consume littleer than the direct punching, and the stamping workpiece atress is balanced, and the noise is low and the vibration is little, and stamping pressure is big.
