Description

Lever type mechanical stamping device

Technical Field

The utility model belongs to a machinery, concretely relates to lever mechanical stamping 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.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model aims to provide a lever type mechanical stamping device.

The utility model provides a technical scheme that above-mentioned technical problem adopted is:

the utility model relates to a lever mechanical stamping device comprises upper shaft, axis, lower shaft, two upper and lower bars boards, gear, motor, connects through the axis between two bars boards, and the axis both ends are connected with the bearing respectively, and the centre passes through connecting rod and gear connection, and motor drive gear goes up the bar board and passes through the upper shaft connection roof, and the upper shaft both ends are connected with the frame, and lower bar board passes through the lower shaft and is connected with the last mould of die forging equipment, and the lower shaft both ends are connected with the frame.

Furthermore, the connecting ends of the upper and lower lever plates are provided with lubricating structures, grooves are arranged in the upper and lower lever plates and connected with pipelines of the lubricating structures, and the grooves are 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, copper sleeves are additionally arranged between the upper bar plate, the lower bar plate and the middle shaft. Contact through copper sheathing and axle, increase the life of going up the lever plate and putting down the lever plate.

Furthermore, a copper sleeve between the upper lever plate and the lower lever plate is combined into a circular ring, and an oil groove is formed in the inner wall of the copper sleeve.

Further, the lower end of the stamping device is connected with a backing plate.

The utility model has the advantages that:

the utility model discloses structural connection is simple, and occupation space is little, moreover through above-mentioned two board lever stamping structure, the stamping workpiece atress is balanced, and the noise is low and the vibration is little, and lever punching press utilizes lever principle directly to dash the energy can be saved.
