Abstract
Increase the method for coiling machine rubber bush external diameter the invention discloses a kind of, it includes：First rubber bush is prolonged into circumferencial direction uniformly to rule, four arc-shaped rubber bush are divided into using hacksaw, expanding sleeve is acted on；First rubber bush is the rubber bush scrapped；Four arc-shaped rubber bush are circumferentially uniformly fixed on the second rubber bush outer surface along the second rubber bush；Second rubber bush is the rubber bush that can normally use.The present invention provide it is above-mentioned mainly use two rubber bush closed assemblies, so as to reduce cost to greatest extent.
Description
Technical field
It is more particularly to a kind of to increase the side of coiling machine rubber bush external diameter the present invention relates to technical field of ferrous metallurgy
Method.
Background technology
In the production process of cold-rolled steel coils, in order to avoid occurring during smooth, rewinding because mandrel breathing is produced
Raw " volume print " defect, uses rubber bush typically on the coiling machine in the region.Rubber bush can be eliminated effectively " volume print "
Defect, has certain breathing amount to ensure normal last volume again.Generally, most of downstream client needs internal diameter to be 610mm
Coil of strip, sleeve diameter according to mandrel for recoiling machine size set, sleeve outer diameter mandrel expansion after be 610mm.
In the market portions of client is because the restriction of itself unwinding device is, it is necessary to which internal diameter is 762mm coil of strip.In addition, cold
Roll the segmental defect product occurred in production process can also be by being expanded to 762mm, so as to reach return acid by coil of strip internal diameter
The secondary rolling of progress is rolled to improve coil of strip qualification rate, the purpose for rate of reducing the number of rejects and seconds.But the change to production line is larger, life is caused
Produce the lifting of cost.
The content of the invention
In order to solve the above technical problems, the present invention provides a kind of method of increase coiling machine rubber bush external diameter.
The present invention provides a kind of method of increase coiling machine rubber bush external diameter, and it includes：
Step a, prolongs circumferencial direction by the first rubber bush and uniformly rules, and four arc-shaped rubbers are divided into using hacksaw
Rubber sleeve, acts on expanding sleeve；First rubber bush is the rubber bush scrapped；
Step b, four arc-shaped rubber bush are circumferentially uniformly fixed on outside the second rubber bush along the second rubber bush
Surface；Second rubber bush is the rubber bush that can normally use.
Further, the step b is specially：
Four arc-shaped rubber bush are tentatively fixed on the along the second rubber bush is circumferential uniform using industry adhesive
Two rubber bush outer surfaces；Then four arc-shaped rubber bush are finally fixed at the second rubber respectively using 4 row M12 bolts
Sleeve outer surface.
The present invention compared with the prior art, with following significant advantage and effect：
(1) due in the market need the client of 762 millimeters of coil of strips of internal diameter and need by coil of strip internal diameter expand into 762 millimeters lack
Fall into product little.Therefore, the present invention mainly uses two rubber bush closed assemblies, so as to reduce cost to greatest extent.
(2) to buying the mandrel of uncoiler of 762 millimeters of coil of strip clients of internal diameter and needing coil of strip internal diameter expanding into 762 millimeters
The acid of faulty goods, which rolls mandrel of uncoiler, fully to be investigated, complete a diameter of 727 millimeters after the contraction completely of downstream mandrel of uncoiler
Full expanded diameter is 762 millimeters, breathing size.Find minimum coil of strip internal diameter, i.e., the minimum external diameter of improved rubber bush
Needs can just be met by reaching 730 millimeters.
Brief description of the drawings
Fig. 1 is according to the method improved shape rubber bush structure of the invention provided.

Embodiment
In order that those skilled in the art more fully understand the present invention program, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.
In a kind of specific embodiment, the method for coiling machine rubber bush external diameter is increased the invention provides a kind of.
Improved shape rubber bush structure is as shown in Figure 1 in the method.This method specifically includes following steps：
Step a, prolongs circumferencial direction by the first rubber bush and uniformly rules, and four arc-shaped rubbers are divided into using hacksaw
Rubber sleeve 1, acts on expanding sleeve；First rubber bush is the rubber bush scrapped；
Four arc-shaped rubber bush 1 are uniformly fixed on the second rubber bush 2 by step b along the second rubber bush 2 is circumferential
Outer surface；Second rubber bush 2 is the rubber bush that can normally use.
Further, the step b is specially：
Four arc-shaped rubber bush 1 are uniformly tentatively fixed on along the second rubber bush 2 is circumferential using industry adhesive
The outer surface of second rubber bush 2；Then four arc-shaped rubber bush 1 are finally fixed at respectively using 4 row M12 bolts 3
The outer surface of two rubber bush 2.
The method that the present invention is provided is, by a rubber bush scrapped, to prolong circumferencial direction and uniformly rule, use steel
Saw, is divided into pintongs.It is tentatively fixed on using industry adhesive on the rubber bush that another can normally use,
Then it is fixed in using 4 row's M12 bolts on the rubber bush normally used, so as to reach the purpose of increase external diameter.
The present invention compared with the prior art, with following significant advantage and effect：
(1) due in the market need the client of 762 millimeters of coil of strips of internal diameter and need by coil of strip internal diameter expand into 762 millimeters lack
Fall into product little.Therefore, the present invention mainly uses two rubber bush closed assemblies, so as to reduce cost to greatest extent.
(2) to buying the mandrel of uncoiler of 762 millimeters of coil of strip clients of internal diameter and needing coil of strip internal diameter expanding into 762 millimeters
The acid of faulty goods, which rolls mandrel of uncoiler, fully to be investigated, complete a diameter of 727 millimeters after the contraction completely of downstream mandrel of uncoiler
Full expanded diameter is 762 millimeters, breathing size.Find minimum coil of strip internal diameter, i.e., the minimum external diameter of improved rubber bush
Needs can just be met by reaching 730 millimeters.
The method to increase coiling machine rubber bush external diameter provided by the present invention is described in detail above.Herein
Apply specific case to be set forth the principle and embodiment of the present invention, the explanation of above example is only intended to help
Understand the method and its core concept of the present invention.It should be pointed out that for those skilled in the art, not taking off
On the premise of from the principle of the invention, some improvement and modification can also be carried out to the present invention, these are improved and modification also falls into this
In invention scope of the claims.
