Crank press die-mounting height regulation transmission device

Abstract

The invention discloses a crank press die-mounting height regulation transmission device. The device comprises a worm, a worm wheel, a small conical gear, a large conical gear, a flange motor, a connecting sleeve, a worm base, a sliding block, a telescopic precise universal coupling, a transition shaft and a rotary coder, wherein a flange motor is fixed on one side of the sliding block; the small conical gear is fixed on the output shaft of the flange motor; the large conical gear meshed with the small conical gear is fixed at the head part of the upper end of the worm; the two ends of the worm are respectively supported on a corresponding worm base through bearings. The two ends of the telescopic precise universal coupling are respectively hinged with the upper end of the worm and the lower end of the transition shaft; the upper end of the transition shaft is fixedly connected with the input shaft of the rotary coder via the connecting sleeve. The crank press die-mounting height regulation transmission device has a compact structure, and is convenient to mount, use and maintain. The crank press die-mounting height regulation transmission device can effectively compensate the different axiality deviation of the worm and the transition shaft, caused by the deviation of the mounting position of the worm base, so that the normal working of the rotary coder is effectively ensured, and the accurate regulation of the crank press die-mounting height regulation transmission device is ensured.

Description

technical field [0001] The invention relates to a device for adjusting the die height of a crank press, in particular to a transmission device for adjusting the height of a crank press with an enlarged bottom surface of a slider, and belongs to the technical field of forging equipment. Background technique [0002] The die height of the crank press refers to the distance between the bottom surface of the slider and the working table when the crank reaches the bottom dead center. Because the crank press is used for different types of plastic forming processes such as stretching, stamping, extrusion and die forging, or because of the different sizes of the processed parts, it is necessary to adjust the die height of the crank press to meet the requirements of different working conditions. The adjustment of the die height is to turn the nut connected with the slider and the connecting rod sleeve, so that the screw and the nut move relatively to change the length of the connec...

AI Technical Summary

Problems solved by technology

At present, in closed small and medium-sized crank presses with enlarged bottom surface of the slider, due to the increased distance between the worm and the rotary encoder, the installation position of the worm itself and the deflection of the worm after being stressed, the worm and the rotary encoder Different shafts affect the adjustment of the die height, which in turn affects the performance of the entire crank press
