Abstract
The utility model discloses an oil scraper roller of a Sendzimir twenty-roller rolling mill. The oil scraper roller of the Sendzimir twenty-roller rolling mill is characterized in that circular grooves are formed in two ends of an oil scraper roller body, the inner side of each groove is in the shape of a cone, a roller shaft is inserted into each groove, the inner side of the roller shaft is hollow, the roller shaft is a hollow cylinder, and the shoulder portion of the oil scraper roller body is increased to 5.5 millimeters from original 2 millimeters. The oil scraper roller of the Sendzimir twenty-roller rolling mill is low in improvement cost and simple and easy to implement, after the improvement, the phenomena that the oil scraper roller cracks, and abrasion between the end face of the oil scraper roller and a bearing seat are basically eliminated, and at the same time, the potential safety hazard that the rolling mill is on fire due to the abrasion between the end face of the oil scraper roller and the bearing seat is avoided.
Description
Technical field
The utility model relates to a kind of Sendzimir twenty roller mill oil-scraping roller.
Background technology
At present at cold rolling twenty roller mill of cold-rolling stainless steel, major part all is to adopt oil-scraping roller shown in Figure 1, because this oil-scraping roller shaft shoulder only has 2 millimeters, need fill 3 millimeters pad before the dress bearing, if forgotten the dress pad, just cause bearing block and roller end surface to produce friction, cause and catch fire (steel band cooling usefulness be ROLLING OIL), the defective that another is fatal, be exactly oil-scraping roller when belt plate shape is bad because unbalance stress, easily from the escape fracture, cause the steel band fracture or cause and catch fire.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of Sendzimir twenty roller mill oil-scraping roller, has avoided milling train four roller oil-scraping rollers and bearing block to cause friction and oil-scraping roller fracture, the potential safety hazard that causes milling train to catch fire.
The technical solution adopted in the utility model is: Sendzimir twenty roller mill oil-scraping roller is characterized in that: the groove of oil-scraping roller two ends opened round, and groove is inboard to be taper, in the roll shaft insertion groove, the roll shaft inboard is hollow, and roll shaft is hollow circular cylinder, and the oil-scraping roller shaft shoulder is increased to 5.5mm by original 2mm.
The method is that oil-scraping roller is divided into the processing of two bodies, is assembled at last a roller, and after transforming, the shaft shoulder is widened (present 5.5 millimeters, originally 2 millimeters) can directly fill bearing, does not need cushioning to reduce installation procedure, reduces error.
The Sendzimir twenty roller mill oil-scraping roller that the utility model provides: in the roll shaft insertion groove, the groove inboard is conical hollow, has increased to be subjected to force intensity, has reduced the probability of roller fracture; When being subject to inhomogeneous pressure, small displacement can occur in the body of roll and axle, has reduced oil-scraping roller and has acted on radial load on the bearing, has reduced the damage of bearing, has prolonged bearing service life.This plant modification is with low cost, and is simple, after transforming elimination the phenomenon of oil-scraping roller fracture and oil-scraping roller end face and bearing block friction, also avoided the hidden danger of catching fire that causes thus simultaneously.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of existing oil-scraping roller.
Fig. 2 is the structural representation (broken section) of the utility model oil-scraping roller.
1 is oil-scraping roller among the figure, and 2 is escape, and 3 is the shaft shoulder, and 4 is roll shaft, and 5 is groove.
The specific embodiment
Embodiment:
Fig. 1 is the structural representation of existing oil-scraping roller, and the shaft shoulder 3 of oil-scraping roller 1 only has 2 millimeters, need fill 3 millimeters pad before the dress bearing, if forgotten the dress pad, just causes bearing block and roller end surface to produce friction, causes and catches fire; And oil-scraping roller because unbalance stress easily ruptures from escape 2, causes the steel band fracture or causes and catch fire when belt plate shape is bad.
Fig. 2 is the structural representation (broken section) of the utility model Sendzimir twenty roller mill oil-scraping roller, the groove 5 of oil-scraping roller 1 two ends opened round, groove 5 inboards are taper, in roll shaft 4 insertion grooves 5, roll shaft 4 inboards are hollow, roll shaft 4 is hollow circular cylinder, and the shaft shoulder 3 of oil-scraping roller 1 is increased to 5.5mm by original 2mm.
This novel rolling mill oil-scraping roller is transformed through on probation at the Taiyuan Iron and Steel Co. cold rolling mill, and result of use is splendid, has thoroughly eliminated because the disaster hidden-trouble that the factors such as oil-scraping roller fracture cause.The firing accident that trial employment period does not occur to cause thus together, also reduced simultaneously the usage quantity of oil-scraping roller and bearing, reduced production cost, expectation will bring economic benefit as follows: 100,000 yuan on year saving oil-scraping roller and bearing, also reduced in addition because the steel scrap volume that oil-scraping roller causes loses approximately 1,000,000 yuan.
