Description
Technical field
The utility model belongs to milling train rolling head technical field, more particularly to a kind of planetary rolling rolling head.
Background technology
Rolling uses three-roll planetary rolling method in copper tube process, needs to use one kind in this process equipment
Planet rolling head device, rolling head are equipped with the bearing outside the roll and pressure set of similar taper by pressure set with pressure set end
Composition, roll needs to repair a die after use finishes certain yield every time, therefore dimension of roller can reduce, to make pressure cover
Position need adjust could produce stable rolling discharge nozzle base size during the rolling process, in the prior art rolling head bearing with
Bearing inner race is fitted close, and adjustment pressure set position is by mobile inner ring, this phenomenon inner ring and bearing roller pearl are easy to wear, and rolling head makes
It is low with the service life.
Utility model content
The purpose of this utility model is to provide a kind of planetary rolling rolling head, provide it is a kind of it is simple in structure, efficiently reduce
The wear rate of equipment, the planetary rolling rolling head device saved equipment investment expense, improve production efficiency.
In order to solve the above technical problems, the utility model is achieved through the following technical solutions：
The utility model is a kind of planetary rolling rolling head, including roll and pressure cover, and the pressure is socketed in outside roll,
The pressure puts on the bearing inner race with steel bushing that sets one, and the steel bushing end face is equipped with a groove；Wherein, the bearing inner race
Outer surface interference fit has a self-aligning bearing；The corresponding position that the pressure set is connect with steel bushing is equipped with compatible with groove
Positioning pin.When dimension of roller changes, movement of the positioning pin in steel bushing is covered by pressure and is adjusted, rather than changes axis
The position held is adjusted, to reduce the abrasion of bearing and bearing inner sleeve.
Further, the inner surface of the bearing inner race is provided with a recess corresponding with groove, the recess it is transversal
Face is trapezium structure.
Further, 23148 self-aligning bearing of model of the self-aligning bearing.
Further, the length of the positioning pin is the range of 5-15cm, preferably 10cm.
In view of rolling head Impact direction is rake angle, self-aligning bearing plays aligning effect, while also having axially and radially
Support force alleviates the bearing capacity of bearing, therefore 23148 self-aligning bearing of model is had chosen in this design scheme；In order to reduce
The problem of bearing inner race abrasion caused by pressure set is mobile and the abrasion of bearing, uses position of bearings in this programme and fixes,
Bearing inner race and the close-fitting design scheme of bearing.
The utility model has the advantages that：
Technical solution described in the utility model, wear rate that is simple in structure, effectively reducing equipment have saved equipment
Investment cost improves production efficiency.
Certainly, any product for implementing the utility model does not necessarily require achieving all the advantages described above at the same time.

Make, therefore should not be understood as limiting the present invention.
Please refer to Fig.1 shown in -3, the utility model be a kind of planetary rolling rolling head, including roll 1 and pressure set 5, it is described
Pressure set 5 is socketed in outside roll 1, and a bearing inner race 3 with steel bushing 4 is set on pressure set 5, and 4 end face of steel bushing is equipped with a groove
401；Wherein, the outer surface interference fit of bearing inner race 3 has a self-aligning bearing 2；The corresponding position that pressure set 5 is connect with steel bushing 4
It is equipped with positioning pin compatible with groove 401 6.
Wherein, the inner surface of bearing inner race 3 is provided with a recess 301 corresponding with groove 401, the cross of the recess 301
Section is trapezium structure.
Wherein, 23148 self-aligning bearing of model of self-aligning bearing 2.
