Description
Technical field
The utility model relates to strip manufacturing machine equipment technical fields, extract in particular, being related to a kind of strip pickling
Roll structure.
Background technique
The technological process of production of cold-strip steel is general are as follows: using hot-strip as raw material, first in pickling unit
Pickling is carried out, cold rolling, heat treatment, finishing procedure are then successively carried out.Hot-strip leaves the afterbody pickling of pickling unit
When slot, the squeeze roller that the acid solution of belt steel surface need to be arranged at afterbody descaling bath notch is squeezed out.Due to output strip line
The steel strip thickness of middle production is different, for example, when the steel strip thickness of production increases to 16mm by 12.7mm, in acid pickling step
In, if continuing to will cause roll breakage using original squeeze roller and frequently occur, in addition the installation ruler by equipment each in production line
Very little influence can be serious if the roller for being able to satisfy the pickling squeeze roller for producing 16mm plate thickness strip of larger number of replacement
The yield and product quality of production line are influenced, failure rate is increased, it is therefore necessary to which structure optimization is carried out to existing squeeze roller.
Utility model content
The purpose of the utility model is to overcome the above deficiencies in the existing technologies, and provide a kind of novel design,
Structure is simple, and energy strict guarantee 16mm plate thickness strip smoothly, normally produces, and does not occur roll breakage phenomenon, does not influence production line output
And roll structure is extracted in product quality, a kind of pickling that can reduce failure rate.
The technical scheme in the invention for solving the above technical problem is:
A kind of strip pickling extracts roll structure, including roll body, it is characterised in that: and the roll body is in cylindrical tube shape, and two
End is connected separately with central spindle；One layer of rubber anti-corrosive layer is enclosed on the roll body and central spindle；The central spindle includes axle body and inserts
Connector, central spindle are mounted on the end of roll body by connection-peg, and the diameter of axle body is less than the diameter of connection-peg, axle body and connection-peg
Junction is arc transition structure.
Preferably, the arc radius of arc transition structure described in the utility model is 100mm.
Preferably, the internal diameter of roll body described in the utility model is 173mm, the wall thickness of roll body is 21mm, by the wall of roll body
Thickness is increased to 21mm by original 18mm, to improve the intensity for entirely extracting roll structure.
Preferably, the rubber anti-corrosive layer wrapped up on roll body described in the utility model with a thickness of 20mm, rubber anti-corrosive layer
Pickling solution can be prevented, which to be splashed on roll body, causes burn into reduce the service life it.
Preferably, being equipped with a pair of of drip ring on axle body described in the utility model, pickling solution is prevented to be splashed to production line
Other drive apparatus in.
Preferably, connection-peg described in the utility model is connect with roll body by welding, central spindle and roller ensure that
The bonding strength of body improves the safety coefficient of production operation.
The utility model compared with prior art, has the following advantages that and effect: axle body and connection-peg junction are designed as
Arc transition structure, arc radius 100mm, and the wall thickness of roll body is increased to 21mm by original 18mm, to mention
The high intensity for entirely extracting roll structure, by the maximum allowable upper limit value of thickness of the coil of strip strip produced on production line by 12.7mm
It has been increased to 16mm, and has prevented the generation of roll breakage accident.
