Pinch roll precision adjusting device

Abstract

The invention discloses a pinch roll precision adjusting device which is used for metal plate strip production equipment. The adjusting device is placed between racks on the two sides of a lower pinchroll and a bearing pedestal, a base of the adjusting device and the racks are fixed together through first screws, a wear-resisting plate is connected with the bearing pedestal through a second screw, a screw rod ejected on the bottom of the wear-resisting plate is in threaded connection with the base, the middle of the screw rod is marked with scale lines, after the precision of a pinch roll isadjusted, the screw rod is locked on the base through a round nut, the head of the screw rod is externally hexagonal, the scale lines of the middle mark equally divide the circumference into 100 parts, remaining parts are outer threads with the screw pitches being 2 mm, the center of the base is an inner thread with the screw pitches being 2 mm, and is in threaded connection with the screw rod, and the device has the most obvious characteristic that the screw rod is rotated to jack the bearing pedestal, position precise of the two sides of the lower pinch roll can be adjusted, equally-dividingscale lines on the screw rod enable adjusting amount to be readable, controllable and precise, the structure is compact, and an adjusting method is simple and efficient.

Description

technical field [0001] The invention relates to the technical field of metal strip production equipment, in particular to a pinch roller precision adjustment device. Background technique [0002] At present, in the strip steel production and processing line in the metallurgical industry, pinch rolls are very important equipment, usually used in pairs, divided into upper pinch rolls and lower pinch rolls. Generally, the lower pinch roller is fixed, and the upper pinch roller presses the gap between the two rollers with the thrust of the air cylinder or hydraulic cylinder, so as to drive the metal sheet to the specified direction, and the position accuracy of both sides of the lower pinch roller It plays a key role in whether the metal strip is deviated during the pinching process. In the prior art, the position accuracy adjustment method on both sides of the lower pinch roller is mainly to add backing plates between the bearing seats and the frame on both sides of the lower ...
