Description

A kind of pipe mill feeding supports seat

Technical field

This utility model belongs to Machining Technology field, is specifically related to a kind of pipe mill feeding and supports seat.

Background technology

Existing pipe mill feeding supports seat and is made up of support and copper sheathing etc., and copper sheathing is fixed on support, it is impossible to rotate, core Bar determines angle rotation due to powerful roll-force with periodic in the operation of rolling, and core bar can produce bigger shake, shake Time main strength concentrate on the lower section of copper sheathing, it will below copper sheathing, grind an oval hole, allow support become the most concentric Cause shake to increase, so can directly influence the precision of rolling and the quality of product, meanwhile, also can damage support seat, and then Cause equipment fault.

Utility model content

In view of this, the purpose of this utility model is to provide a kind of pipe mill feeding to support seat, by rotating core bar band Dynamic pipe, thus drive lining to rotate, it is to avoid the eccentric wear of lining, improves the use cycle of lining, and has saved and be manufactured into This.

For reaching above-mentioned purpose, this utility model following technical scheme of offer:

A kind of pipe mill feeding supports seat, including support with arrange lining on the bracket, and described support and described Being provided with between lining and be easy to the rolling bearing that described lining rotates, the outer ring of described rolling bearing is fixed with described support, interior Circle is fixed with described lining, and described lining one end is provided with the shaft shoulder being adjacent to described rolling bearing inner ring end face, and the other end sets It is equipped with the back-up ring being adjacent to described rolling bearing inner ring other end.

Further, described support is additionally provided with the pedestal cap being easy to dismount described rolling bearing.

Further, the bearing block being easy to fix described rolling bearing it is provided with between described support and described pedestal cap Hole, the two ends of described bearing saddle bore are provided with and limit the limited step that described housing washer moves axially.

Further, the material of described lining is nylon.

The beneficial effects of the utility model are:

The first, a kind of pipe mill feeding that this utility model provides supports seat, in the operation of rolling, by rotating core bar band Dynamic pipe, thus drive lining to rotate, it is to avoid the eccentric wear of lining, improves the use cycle of lining.

The second, a kind of pipe mill feeding that this utility model provides supports seat, and lining uses nylon material, it is to avoid pipe Very stiff and demanding with the inner ring of rolling bearing, improve the service life of rolling bearing, and low cost of manufacture, replacing are conveniently.

Detailed description of the invention

Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in detail.

A kind of pipe mill feeding supports seat, including support 1 and the lining 2 being arranged on support 1, sets between support 1 and lining 2 Being equipped with and be easy to the rolling bearing 4 that lining 2 rotates, the outer ring of rolling bearing 4 is fixed with support 1, and inner ring is fixed with lining 2, lining 2 One end is provided with the shaft shoulder being adjacent to rolling bearing 4 inner ring end face, and the other end is provided with and pastes with rolling bearing 4 inner ring other end Tight back-up ring 3.During core bar inserts pipe in embodiment, rotate plug by determining angle, thus drive pipe blank rotary, by serving as a contrast Set 2 is fixed on rolling bearing 4 inner ring, lining 2 can be followed pipe and be rotated together, it is to avoid the eccentric wear of lining 2, improves lining In the service life of 2, meanwhile, avoid pipe very stiff and demanding with the inner ring of rolling bearing 4 by installing lining 2 additional, improve rolling bearing 4 Service life.

In the present embodiment, support 1 is additionally provided with the pedestal cap 5 being easy to disassembling and assembling rolling bearing 4.Employing in embodiment Pedestal cap 5 fixes bearing, installation, convenient disassembly.

In the present embodiment, between support 1 and pedestal cap 5, it is provided with the bearing saddle bore being easy to fixing rolling bearing 4, bearing The two ends of bore are provided with and limit the limited step that rolling bearing 4 outer ring moves axially.The two ends of the bearing saddle bore in embodiment Arranging limited step, the aperture at limited step is more than the diameter of bearing inner race, it is to avoid rolling bearing inner ring rotation central axis to Channel bit and limited step collision, simple in construction, easy for installation.

In the present embodiment, the material of lining 2 is nylon.Lining 2 in embodiment uses nylon manufacture, it is to avoid pipe and rolling The inner ring of dynamic bearing 4 is very stiff and demanding, improves the service life of rolling bearing, and low price, processing are simple.

Finally illustrating, preferred embodiment above is only in order to illustrate the technical solution of the utility model and unrestricted, to the greatest extent This utility model is described in detail by pipe by above preferred embodiment, but those skilled in the art should manage Solve, in the form and details it can be made various change, without departing from this utility model claims institute The scope limited.
