Description
Technical field
The present invention relates to the rolling equipment field of metal pipe material or wire and rod, particularly to the swing arm roll mill of the adjustable roll gap of a kind of dead axle transmission.
Background technology
At present, in roll seamless steel tube production line, milling train is the main extensional equipment of seamless steel pipe.Three-roller tandem rolling tube machine constitutes rationally due to its pass, and uniformly, therefore product wall thickness accuracy and surface quality are higher in the hollow forging deformation of rolling.
Patent CN1293600 discloses a kind of rolling machine frame with three or more adjustable arms, three roll assemblings being arranged in swing arm can be made to rotate around milling axis, to adjust the position of roll.
Patent CN101195125 and CN101658866 discloses a kind of three-high mill, and the roller sliding base being connected with roll is slided along the gathering sill vertical with roller central line.Owing to roller central line moves radially along pressure direction all the time, roll centre lateral symmetry pass point linear velocity is consistent.
Patent CN103302101 discloses a kind of swing arm rolling machine frame, the hinged centrage of swing arm assembling is vertical with rolling centerline, and therefore, swing arm is assemblied in swing process, roll symmetrical pass point also remains symmetrical in swing arm equipment adjustment process, and has identical linear velocity.
In above-mentioned patent, roll is directly and propeller shaft couplings, but the reason due to roll gap regulation, the centrage of roll is change in the whole operation of rolling, cause the shaft coupling needing apolegamy particular design, to adapt to the change of this centrage, this configuration causes that automatically changing of rolling machine frame is extremely difficult；And owing to roll needs individually to drive, each roll is required for configuring a set of drive system, causes that drive system is huge.
Summary of the invention
The shortcoming of prior art in view of the above, it is an object of the invention to provide the swing arm roll mill of the adjustable roll gap of a kind of dead axle transmission, it can realize roll gap regulation function, can realize again power transmission shaft fixed conveyor, it is ensured that oscillation center line is parallel with roll axis and distance is fixing.
For achieving the above object and other relevant purposes, the present invention provides the swing arm roll mill of the adjustable roll gap of a kind of dead axle transmission, including frame, it is hingedly mounted on the many groups swing arm roll assembling in frame, often organize in the assembling of described swing arm roll and be provided with roll mandrel and the roll being arranged on roll mandrel, it is additionally provided with the fixing axle parallel with described roll mandrel in the assembling of described swing arm roll, described roll mandrel is fixed with roll mandrel gear, described fixing axle is fixed with fixing shaft gear, described roll mandrel gear and fixing shaft gear intermesh transmission power, the assembling of described swing arm roll swings around fixing shaft centre line, make roll rotation centrage parallel with the oscillation center line that swing arm roll assembles, and the distance of rotary centerline and oscillation center line keeps constant.
Many groups swing arm roll assembling of hinged installation in frame, has collectively constituted the swing arm roll-separating mechanism in rolling machine frame.In above-mentioned roll-separating mechanism, roll assembling is connected in the swing arm of swing arm roll assembling, the overall fixing axle in frame of swing arm roll assembling swings, the rotary centerline of roll is parallel with the oscillation center line of swing arm, needs due to roll gap regulation, in existing technical scheme, the pivot center position of roll is change.And the present invention by being respectively provided with a parallel-axes gears on roll mandrel and fixing axle, i.e. roll mandrel gear and fixing shaft gear, the paired use of parallel-axes gears, the axis power transmission that becomes of roll mandrel is converted into the oscillation center line power transmission of fixing axle.Due to the constant distance of above-mentioned centrage, therefore, above-mentioned two parallel-axes gears is constantly in optimal engagement state, does not affect the normal operation of roll-separating mechanism simultaneously.
As preferably: the assembling of described swing arm roll is at least three groups, and the oscillation center line that swing arm roll is assemblied in frame is vertical with rolling centerline.
The assembling of swing arm roll can arrange four groups, five groups, six groups etc. according to designing requirement.
As preferably: often organizing the assembling of described swing arm roll and be correspondingly arranged on a trunnion type compensating cylinder, described trunnion type compensating cylinder is arranged in frame, and hinged with the assembling of swing arm roll.
As preferably: described swing arm roll is assembled into three groups, the fixing axle of first group of swing arm roll assembling is fixed with first bevel gear, the fixing axle of second group of swing arm roll assembling is fixed with second bevel gear, the fixing axle of first group of swing arm roll assembling is fixed with two third hand tap gears, described second bevel gear and one of them third hand tap gear intermesh, first bevel gear and another third hand tap gear intermesh, the power of the described fixing axle of first group of swing arm roll assembling is delivered on the fixing axle of all the other two groups of swing arm roll assemblings respectively, realize central driving.
Owing to being provided with many group roll assemblings in rolling machine frame, in currently used transmission scheme, all need to configure the drive system that many groups are independent.By installing bevel gear on above-mentioned fixing axle, the power of fixing axle is transmitted and couples together, it is only necessary to drive one of them fixing axle, the rotation of all fixing axles can be driven, thus realizing the driving of all rolls.
As preferably: described roll mandrel gear and fixing shaft gear are the one in spur gear, helical gear, herringbone bear.
