Fastening device for assembling water stop ring of supporting roller

Abstract

The invention discloses a fastening device for assembling a water stop ring of a supporting roller. The fastening device comprises arc pieces with same shapes and certain thicknesses spliced into a round tube shape. A channel that is as long as the inner circumference of the arc pieces is formed in the upper portion of the inner circumference of the arc pieces. A semicircular lining ring is contained in the channel. A plurality of through holes are formed in the two ends in the circumferential direction of the arc pieces. After every two adjacent arc pieces are spliced, bolts penetrate throughthe plurality of through holes and then nuts are screwed at the ends of the bolts such that the arc pieces are fixed. Hanging lugs are disposed on the outer circumference of the arc pieces. The fastening device can meet the requirements of roller necks of various rollers by changing the diameter of the lining ring, namely by preparing lining rings of different diameters, thereby reducing cost by90% or more; and once the inner circumference of the lining ring is damaged during specific production, the lining ring can be replaced in time, so that safety is higher and work efficiency is higher.

Description

technical field [0001] The invention belongs to the field of rolls, and in particular relates to a fastening device with long service life and good applicability for assembling water retaining rings of backup rolls. Background technique [0002] Cold rolls generally need to be installed vertically on the quenching machine for quenching. The hoisting process requires the use of clamps, which are mainly used to clamp the roll necks of the rolls. In specific production, there are many types of rolls produced by roll manufacturers, and the diameters of the roll necks are also inconsistent. However, the inner circumference of the traditional fixture is fixed, and one fixture can only be used for a type of roll with the same diameter. Different fixtures are required for different types of rolls, which leads to an increase in production costs. At the same time, when using one fixture for a long time to process a type of roll, the inner circumference of the fixture is prone to defor...

Problems solved by technology

In specific production, there are many types of rolls produced by roll manufacturers, and the diameters of the roll necks are also inconsistent. However, the inner circumference of the traditional fixture is fixed, and one fixture can only be used for a type of roll with the same diameter. Different fixtures are required for different types of rolls, which leads to an increase in production costs. At the same time, when using one fixture for a long time to process a type of roll, the inner circumference of the fixture is prone to deformation, resulting in potential safety hazards and short service life.
