Scraper mechanism of cold-rolling emulsion magnetic filter

Abstract

The invention relates to a scraper transmission mechanism of a cold-rolled emulsion magnetic filter, belonging to the technical field of cold-rolling equipment in the metallurgical industry. The technical solution is: including track (1), car body (2), upper scraper arm (3), lower scraper arm (4), upper top wire (5), lower top wire (6), cylinder (7) and scraper (12), the car body (2) is set on the track (1), the upper scraper arm (3) and the lower scraper arm (4) are respectively fixed on the car body (2) through pin shafts, the upper scraper arm (3) and One end of the lower scraper arm (4) is connected by a cylinder (7), and the other ends of the upper scraper arm (3) and the lower scraper arm (4) are respectively equipped with a scraper (12), the upper scraper arm (3) and the lower scraper arm ( 4) There are upper top wire (5) and lower top wire (6) respectively. The invention has the beneficial effects of avoiding the damage to the motor, the chain connection block and the pin shaft structure when the four-bar linkage mechanism in the prior art hits the block, and effectively improving the operating life of the scraper transmission mechanism.

Description

technical field [0001] The invention relates to a scraper transmission mechanism of a cold-rolled emulsion magnetic filter, belonging to the technical field of cold-rolling equipment in the metallurgical industry. Background technique [0002] During the cold rolling process of the strip, the main function of the emulsion is to cool and lubricate. Since a large amount of iron oxide powder will enter the emulsion during strip rolling, the impurity content of the emulsion will be too high, which will affect the lubrication of the emulsion. As a result, in severe cases, it will cause slippage, deviation and broken belt accidents of the rolling mill. [0003] At present, the main equipment for filtering the iron powder impurities in the emulsion is a magnetic filter. Its working principle is to rely on a group of magnetic rods fixed on the chain to absorb the iron powder impurities in the emulsion, and then the scraper installed on the scraper trolley The iron powder impurities...

AI Technical Summary

Problems solved by technology

However, in the scraper mechanism of the magnetic filter trolley, when the scraper trolley structure is in the open and closed positions of the scraper, its opening and closing action is completed by the four-bar linkage mechanism hitting the stopper. The transmission motor and chain structure cause great mechanical damage

Especially the chain connection block structure located on the transmission base is often broken and damaged due to frequent impacts

Since the magnetic filter has to work for more than 16 hours a day, the chain connection block and the pin shaft are quickly damaged, and it needs to be replaced every 7 days on average, which seriously affects the use efficiency of the equipment, and the iron powder impurities in the emulsion cannot be discharged in time
