Description
The cross reference of related application
The application is the Application U.S. Serial No No.12/797 submitted on June 6th, 2010,656 part continuation application,
The entire disclosure of which is incorporated herein with purport by way of reference.
Background technology
1. technical field
Present invention relates in general to milling train, in particular it relates to be provided for rolling the long products of wire rod, bar etc.
Improved modularization finishing mill.
2.Description of related art
Reference picture 5A, it is known that the United States Patent (USP) No.5 for authorizing Shore, the type described by 595,083 modularization essence
Milling train is included in multiple rolling unit R arranged in sequence on roll line P1-R5, the rolling indicated along roll line P in arrow 10
Product is rolled on direction.Gear unit A1-A4Along the line L arrangements parallel to roll line.Gear unit is respectively by motor
M1-M4Driving, and deviate in the rolling direction relative to rolling unit.By the way that each gear unit is respectively connecting into two
Successive rolling unit provides continuous power train.
Generally, when rolling less product size (for example, a diameter of 2.0-6.5mm wire rod), rolled using all
Unit R processed1-R5, its finishing speeds is up to 120m/s, and tonnage speed is 70-90tons/hr.In this case, milling train is utilized
By all motor M1-M4The power for working and providing via continuous power train, the continuous power train is by each gear unit is joined
Two successive rolling units are connected to provide.However, when with the higher tonnage of relatively low speed and about 150tons/hr
When speed rolls larger product size, one or more rolling units of the port of export of milling train are will be generally located on from roll line
Remove.If removing two rolling units, as shown in Figure 5 B, last motor M4 actually departs from from continuous power train, from
And when due to the power demand increase with higher tonnage speed production, reduce the power that can be used in driving milling train.For
Compensation is this to be short of power, and milling train is equipped with larger motor, which disadvantageously increases the overall cost of milling train.
In above-mentioned milling train, rolling unit R1-R5Include the paired roll of two pairs of reversed dips respectively.The design is module
The theory for changing milling train is exclusive, it is not easy to other milling train occasions are useful in, for example, being unsuitable for the U.S. for authorizing Shore et al.
In the rear finishing mill (post finishing mill) of type described by state patent No.5,325,697.

Embodiment
With reference first to Fig. 1 and 3, shown according to the modular rolling mill of the present invention with 12.Milling train 12 is designed to by arrow 14
In the rolling direction schematically indicated the long products such as bar, wire rod are rolled along roll line " P ".Milling train is included along flat
Row is in roll line P First Line L1The first gear unit A of arrangement1-A4.First gear unit is respectively by motor M1-M4Driving, horse
Up to M1-M4Paired first axle 16 is mechanically connected to by internal gear group 18.
Second gear unit B1-B5Along positioned at First Line L1Between roll line P and parallel to First Line L1And rolling
Line P the second line L2Arrangement.Each second gear unit is respectively provided with a pair of second axles 20 mechanically interconnected by gear train 22.
When being observed along rolling direction, second gear unit B1-B5Relative to first gear unit A1-A4Deviate.The He of first shaft coupling 24
25 are used for each first gear unit A1-A4First axle 16 be connected to two successive second gear unit Bs1-B5Second
Axle 20.Shaft coupling 24 is provides the type uninterruptedly connected, and shaft coupling 25 includes clutch, and the clutch can be with disengagement
To interrupt the drive connection between its corresponding axle 20 of first axle 16 and second.
Rolling unit C1-C10It is successively arranged along roll line P.Rolling unit can be interchangeable with one another.By further joining
According to Fig. 4 can with it is better seen that, each rolling unit is respectively provided with axle 26, and the axle 26 passes through bevel gear 28a, 28b and gear train
30 are connected to the roll shaft 32 of carrying working roll 34.
In addition, reference picture 2A and 2B, roll shaft 32 can be tilted with 45 ° of angle, axle 26 has from rolling unit shell
The end 26 ' and 26 " that relative both sides are stretched out.Second shaft coupling 36 is used for second gear unit B1-B5The second axle 20 connect
To two successive rolling unit C axle 26.Rolling unit C direction can alternately be inverted along roll line P (such as Fig. 2A and
Shown in 2B), to adapt to the alternating of the roll shaft needed for the no twist rolling of product to being rolled to inclination, and adaptation dextrorotation rolling with left-handed
The need for system.
When being observed along rolling direction, the first rolling unit A1-A4Gear train 18 be sized to gradually elevated
Rotary speed drives first axle 16.Similarly, equally observed along rolling direction, second gear unit B1-B5Gear train 22 chi
It is very little to be defined as driving the second axle 20 with elevated rotary speed gradually.
Rolling unit C1-C10Bevel gear 28a, 28b size be determined to become each rolling unit identical percentage be provided
Specific rate increment.So, with such as Fig. 2A with 2B as described in the reversibility of rolling unit be combined so that rolling unit is along rolling
Line P processed any position can be interchangeable with one another, correspondingly, can so be rolled with minimal number of standby rolling unit to run
Machine.
It should also be noted that by by the first and second gear unit A1-A4With B1-B5The continuous transmission arrangments provided,
Quantity regardless of the rolling unit C used, all motor M1-M4It can be used in providing power for milling train.Thus, for example,
As described by Fig. 1 and 3, when rolling less product size, all motor M1-M4It is mechanically coupled to all roll
Unit C processed1-C10.By the way that selected rolling unit is removed from roll line P, it can be rolled with higher tonnage speed larger
Product size.A kind of such situation is described in figure 6, wherein, although by rolling unit C7-C10Moved from roll line
Walk, still, four motor M1-M4Still it is all connected to the remaining rolling unit worked.
In the case of the disengagement of clutch 25, as described in Figure 7, rolling unit C3、C4With C7、C8Can be from rolling
Line P processed is removed.Under this arrangement, driving order would is that：
M1-A1-B1-C1、C2
M2-A2-B3-C5、C6
M3-A3-B3-C5、C6
M4-A4-B5-C9、C10
Likewise, all motors can be used (if however, rolling unit C5、C6On rolling loads only need to one
Motor, then M2Or M3It can shut down).
Such milling train configuration add adapt to different shaped jet holes design flexibility, especially for 10mm with
On larger-diameter product., can be by removing rolling unit (C when performing low temperature thermo-mechanical rolling3And C4Or C7
And C8) and cooling unit (not shown) is placed in the space along roll line vacateed.
Although disclosing embodiments of the present invention by way of example, to those skilled in the art
Speech is it is readily apparent that the spirit of the invention, scope and its equivalent that are illustrated in the claim for not departing from following article
In the case of, many changes, addition can be made and deleted.
