Oil scraping device for silicon steel

Abstract

The invention discloses an oil scraping device for silicon steel. The device comprises an installation clamping groove and an oil scraping strip. The oil scraping strip penetrates into the installation clamping groove, the installation clamping groove is fixed to equipment, the oil scraping strip comprises a boss, a vertical section, an inclined section and a lip opening which are connected in sequence, the oil scraping strip further comprises a high-strength steel belt and a fiber enhancement layer, the high-strength steel belt is in the boss and the vertical section, the upper end of the fiber enhancement layer is on one side of the high-strength steel belt, the lower end of the fiber enhancement layer stretches into the inclined section close to the lip opening, the boss, the vertical section, the inclined section and the lip opening located on the outer side of the high-strength steel belt and the fiber enhancement layer are made from special wear-resisting rubber through heat vulcanization, the section of the lip opening is in an inverted right triangle shape, the included angle a between the inclined edge of the lip opening and the horizontal plane is 15-25 degrees, and the included angle b between the inclined section and the horizontal plane is 30-45 degrees. By using the oil scraping device for silicon steel, the service life is obviously prolonged, the replacement frequency is low, and the using cost is greatly reduced.

Description

technical field [0001] The invention relates to an oil scraping device, in particular to an oil scraping device for cold-rolled silicon steel plates. Background technique [0002] Cold-rolled silicon steel is an indispensable soft magnetic alloy for electric power, electronics and military industries. It is mainly used for the production of transformers, motors, compressors and other products. Because the manufacturing technology is stricter than ordinary steel products, the production process is complicated and the content is higher. Silicon steel It was once called "handicraft in steel products", which is a symbol of the development level of a country's steel industry. At the same time, due to the low yield of silicon steel products, such as the qualified rate of oriented silicon steel, which only reaches 30%-50%, it has been in short supply at present. In the state of high profit, only steel plants with technical strength such as Shougang, Baosteel and Wuhan Iron and Stee...

Problems solved by technology

[0003] like image 3 As shown, the degreaser used in the past is a kind of oil scraper that positions the rubber plate on the pressure plate through bolts. During use, the rubber part in the bolt gap part has serious wear and tear, and the bolt part The rubber part wears less, and after long-term use, it will appear wavy, and there is no self-compensation ability after wear, resulting in poor oil scraping effect and frequent replacement, which seriously affects the product quality of silicon steel
