Intelligent automatic die adjusting mechanism based on oil press principle

Abstract

The invention discloses an intelligent automatic die adjusting mechanism based on an oil press principle, and particularly relates to the field of machining. The intelligent automatic die adjusting mechanism based on the oil press principle comprises a punching bottom plate, a linear guide rod, a punching die and a feeding mechanism, a fixed seat is installed at the top end of the linear guide rod, a tapered wedge moving block is slidably connected to the bottom face of the fixed seat, and a hydraulic jacking mechanism is installed on the bottom face of the fixed seat; and the output end of the hydraulic jacking mechanism is connected with a jacking rod, the top face of the punching die is connected with a tapered wedge pressing die in a clamped mode, and the input end of the hydraulic jacking mechanism is connected with a hydraulic driving mechanism. According to the intelligent automatic die adjusting mechanism, a tapered wedge lifting mechanism is arranged, the tapered wedge movingblock transversely moves on the surface of the tapered wedge pressing die, and the transverse jacking force driven hydraulically is converted into lifting power of the punching die through the taperedwedge lifting mechanism, so that punching of a workpiece is achieved; and compared with a traditional lead screw lifting structure, the tapered wedge lifting mechanism is more stable and higher in structural strength, the tapered wedge lifting mechanism is suitable for punching high-hardness workpieces, the fault rate is low, and the service life is greatly prolonged.

Description

technical field [0001] The present invention relates to the technical field of mechanical processing, and more specifically, the present invention is an intelligent automatic mold adjustment mechanism based on the principle of hydraulic press. Background technique [0002] At present, hydraulic presses include punching for conventional hardware and punching for non-metallic diaphragms after special modification. Next, calculate the linear relationship between the punching depth and the rotation speed of the mold-adjusting motor. The mold-adjusting motor realizes automatic mold adjustment, and the transmission structure controls the four-corner screws to perform synchronous lifting to realize synchronous die-cutting. [0003] However, the synchronous structure of the screw generally increases the rotational torque of the screw through the gear ratio during the transmission process, and then converts the rotation of the screw into the punching kinetic energy of the upper and l...

[0003] However, the synchronous structure of the screw generally increases the rotational torque of the screw through the gear ratio during the transmission process, and then converts the rotation of the screw into the punching kinetic energy of the upper and lower dies through the rotational connection between the upper and lower dies and the screw. In use, when punching thicker or harder steel parts, the teeth on the surface of the screw are prone to broken teeth or the screw is broken due to high torque, and the adjustment accuracy of the screw is limited by the distance between the screw teeth and cannot be infinitely adjusted. , leading to low accuracy of automatic mold adjustment of the hydraulic press, and there are certain defects
