Abstract
A mandrel supporting device of a pipe mill is used for solving the problem that when a mandrel is too long, the deflection of the mandrel during suspension can be increased. The mandrel supporting device of the pipe mill comprises a supporting frame, a V-shaped supporting groove and adjusting gaskets. The supporting frame is located between a stopping device and the mill and is fixedly connected to one side of the stopping device in a welded mode, a square groove is formed in the upper end of the supporting frame and an adjusting gasket assembly and the V-shaped supporting groove used for lifting a mandrel are sequentially arranged in the square groove from bottom to top. The mandrel supporting device of the pipe mill is relatively simple in structure, is arranged close to a roller accessory of the mill, can effectively achieve the supporting effect, is easy to adjust and maintain, and is beneficial for increasing the production efficiency.
Description
Technical field
The utility model relates to seamless steel pipe rolling tube equipment technical field, is specifically related to a kind of mandrel bar bracing or strutting arrangement.
Background technology
At present, in roll seamless steel tube process, limiting bogie plug mostly is vacant state or adopts fixed support, and in the time that plug length is longer, the unsettled meeting of plug strengthens its amount of deflection, has strengthened the inner diameter deviation of steel pipe; Though fixed support has reduced the distortion amount of deflection of plug effectively, in the time that changing, rolling specs can not well adapt to the diameter of plug.
Utility model content
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, provides a kind of plug relatively simple, that easily adjust to lift bracing or strutting arrangement.
For achieving the above object, the utility model adopts following technical proposals:
A kind of mandrel bar bracing or strutting arrangement, it is characterized in that, comprise bracing frame, V-type bracket and adjust pad, described bracing frame is fixed on restraint device one side between restraint device and milling train and by being welded to connect, bracing frame upper end has square groove, and bottom-uply in described square groove is placed with successively adjusting shims part and lifts the V-type bracket of plug.
Described adjusting shims part is that the some grinding steel discs that do not waited by thickness are formed by stacking.
Single spacer thickness in described adjusting shims part comprises 1 millimeter, 2 millimeters, 5 millimeters, 10 millimeters, 20 millimeters and 30 millimeters of six thickness series.
On two groove faces of described V-type bracket, be respectively equipped with one and the vertically disposed rotor of mandrel.
Be provided with the elongated slot of a rectangle at the bottom land of described V-type bracket.
Between support frame as described above and restraint device, be provided with a riser reinforcement.
The beneficial effects of the utility model are that this mandrel bar bracket apparatus structure is relatively simple, is arranged near rolling mill roll annex, can play effective supporting role, and is easy to adjust and safeguard, is conducive to enhance productivity.

Detailed description of the invention
Embodiment mono-, as shown in Fig. 1 to 2,
Below in conjunction with drawings and Examples, the utility model is further elaborated, should be noted that following explanation is only in order to explain the utility model, does not limit its content.
A kind of mandrel bar bracing or strutting arrangement, comprise bracing frame 1, V-type bracket 2 and adjust pad 4, wherein said bracing frame 1 is welded on the rear end of restraint device 5, and limiting bogie moves on the guide rail of restraint device, have a movement travel A, plug 3 is arranged on limiting bogie 6.
Bracing frame 1 is fixed on restraint device one side between restraint device 5 and milling train 8 and by being welded to connect, and bracing frame upper end has square groove, and bottom-uply in described square groove is placed with successively adjusting shims part and lifts the V-type bracket 2 of plug.Wherein adjusting shims part is that the some grinding steel discs that do not waited by thickness are formed by stacking, and the single spacer thickness in adjusting shims part comprises 1 millimeter, 2 millimeters, 5 millimeters, 10 millimeters, 20 millimeters and 30 millimeters of six thickness series, to realize by the mode of increase and decrease pad the effective depth that regulates V-type bracket.
This V-type bracket forms by milling, is the V-shaped groove of 90 degree.
Between above-mentioned bracing frame and restraint device, be provided with a riser reinforcement, to strengthen the integral rigidity of bracing frame, prevent from trembleing in the course of work.
Under use state, V-type bracket 2 upper end slot parts contact with plug 3, and lower end is fixed on bracing frame 1 by adjusting pad 4, and the pad 4 of changing different-thickness can regulate the effective depth of V-type bracket 2.
The described plug bracket device course of work is as follows:
When the utility model specific works, determine that according to the diameter of plug 3 thickness of adjusting pad 4 makes plug 3 and V-type bracket 2 two sides tangent, in the operation of rolling, V-type bracket 2 two sides are tangent with plug 3 all the time, can effectively reduce the deflection deformation of plug 3.
In the time that rolling specs variation need to change plug 3 diameter, the thickness of adjusting pad 4 by change makes the two sides of V-type bracket 2 again tangent with plug 3.
Embodiment bis-
As shown in Figure 3 and Figure 4, be with embodiment mono-difference, on two groove faces of described V-type bracket 2, be respectively equipped with one and the vertically disposed rotor 7 of mandrel.Specifically such, a default circular hole in bracket inclined-plane, and this circular hole extends out on inclined-plane, penetrate a roller in similar cylinder roller bearing, form a rotating rotor, like this, in the operation of rolling, rotor two sides on V-type bracket are tangent with plug all the time, can effectively reduce the deflection deformation of plug 3, reduce frictional resistance between the two simultaneously.
By reference to the accompanying drawings detailed description of the invention of the present utility model is described although above-mentioned; but the not restriction to the utility model protection domain; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various amendments that creative work can make or distortion still in protection domain of the present utility model.
