Abstract
The utility model discloses a forming roll of a spiral weld-pipe mill, belonging to an accessory of a metal rolling device. The forming roll of the spiral weld-pipe mill comprises a central shaft and a forming roll shell and is characterized in that an oil tank is arranged at the middle part of the central shaft, a cylinder roller is arranged between a bearing inner ring and the forming roll shell on the two sides of the oil tank, and an end sleeve is respectively arranged on two sides of the bearing inner ring. A sealing ring is arranged on the outer circumference of the end sleeve. The forming roll disclosed by the utility model has the advantages that the forming roll is designed to be a special cylinder roller bearing structure and simplifies an original structure, each component is easy to machine and form, the cost is low, and the cost of each set of forming roll can be reduced by ** yuan; in addition, the weight bearing of the cylinder bearing structure is strong and the service life thereof is long, and the maintenance and the installation are convenient.
Description
Technical field
The utility model belongs to the format roll of the accessory of metal shaping equipment, particularly spiral weld-pipe mill.
Background technology
Spiral weld-pipe mill is widely used in the manufacturing of steel pipe of various diameters; Wherein format roll is the running stores of using always, and processes is complicated in the maintenance, makes difficulty; And supporting with it accessory (like bearing, gland etc.) price is higher; Assembling, maintenance process complicacy have increased workload, and be time-consuming expensive.
The utility model content
In order to overcome existing format roll maintenance difficult, deficiency that cost is high, the utility model provides a kind of spiral weld-pipe mill format roll, and this spiral weld-pipe mill format roll is not only simple in structure but also assemble easy to maintenance.
The utility model solves the technical scheme that its technical problem adopted: a kind of spiral weld-pipe mill format roll; Comprise central shaft, format roll shell; It is characterized in that: the central shaft middle part is provided with oil groove; The oil groove both sides are equipped with between bearing inner race and the format roll shell cylindrical roller are housed, and the end cover is equipped with in the bearing inner race both sides.
Described end cover excircle is provided with sealing ring.
The beneficial effect of the utility model is that format roll is designed to a special cylindrical roller bearing structure, has simplified original structure, and each parts is easy to machine-shaping; With low cost; With the diameter of axle is 30mm, and external diameter is that the pony roll of 90mm is that the every cover of example can reduce by 50 yuan, and the strong long service life of cylindrical bearing structure bearing capacity; Convenient for maintaining is installed, is reduced labor intensity, and improves workman's condition of work.
