Fine speed regulation device for large-sized mechanical press

Abstract

The invention discloses a fine speed regulation device for a large-sized mechanical press. The fine speed regulation device for the large-sized mechanical press comprises a worm-gear case, a worm gear, a worm and a fine regulation brake, wherein one side of the worm-gear case is fixed on a cross beam; the other side of the worm-gear case is connected with a worm-gear case supporting sleeve; the worm-gear case supporting sleeve and the worm-gear case form a closed case body; the worm gear is arranged in the sealed case body; the worm gear is integrally connected with a worm gear supporting sleeve; the worm gear supporting sleeve is connected with a brake mounting plate; the brake mounting plate is connected with a brake; the brake is connected with a high speed shaft of main drive; one end of the worm is connected with an electric motor through a tire shaft coupling; the other end of the worm is connected with a fine regulation brake; the fine regulation brake is simultaneously fixed on a fine regulation brake combining plate of the worm-gear case; and the left end surface of the fine regulation brake combining plate is in contact with a limiting switch contact. According to the invention, the traditional method for driving a main drive system to realize fine regulation by using a main motor is changed, the fine regulation accuracy is effectively improved, the regulation efficiency is effectively increased, the use frequencies of a main drive clutch and a brake are reduced and the service life of the fine speed regulation device for the large-sized mechanical press is prolonged.

Description

technical field [0001] The invention relates to a press adjusting device, which belongs to the technical field of press components. Background technique [0002] At present, the micro-speed adjustment function on large-scale mechanical presses is realized by adjusting the speed of the main motor and driving the main transmission system with a low speed state: first, turn the knob switch to the fine-tuning position, and the motor will decelerate under the automatic control of the program. After the speed is reduced to the preset speed, the operator performs a micro-speed adjustment operation; during this operation, the accurate position fine-tuning must be achieved by observing the angle feedback display on the button station until the function is completed in the correct position. Due to the limitation of the speed of the main motor and the transmission ratio, the running speed of the final stage transmission is still very fast. If the slider moves past the required adjustme...
