Abstract
The utility model relates to the technical field of cold rollers, in particular to a multifunctional cold roller which comprises a roller shaft, wherein a pair of shaft collars are arranged on the roller shaft, a rolling-groove block is fixedly connected with the circumference surfaces of the shaft collars, the centers of the shaft collars are connected with the roller shaft through a positioning key, and one or two hole pattern (s), of which the radius varies from big to small, is/are formed on the circumference of the rolling-groove block. The multifunctional cold roller not only can roll a pipe at a time, but also can roll two pipes at a time, saves raw materials, reduces the manufacturing cost, and improves the production efficiency; and moreover, the cold roller has the advantages of compact and simple structure, low possibility of deformation, and convenient operation.
Description
Technical field
The utility model relates to the cold-rolling process technical field, especially a kind of multi-functional cold roll.
Background technology
In the cold-rolling process technology, a kind of cold pilger mill is arranged, its roll that comprises contains a roll mandrel and a groove piece that is installed on the roll mandrel usually, is provided with radius pass from large to small on the circumference of groove piece.Adopt this roll rolled pipe period of the day from 11 p.m. to 1 a.m, pipe is being rolled between two groove pieces up and down, present roll once can only a rolling pipe, production efficiency is low, and flexibility ratio is little, if need once rolling two tubes, then need change baroque cold roll, meet the demands, the cost height, operability is low.In practice, will switch in a disposable rolling pipe and these the two kinds of operations of rolling two tubes usually, flexibility ratio is low, and production efficiency is not high yet.
The utility model content
In order to overcome the low deficiency of existing roll production efficiency, the utility model provides a kind of multi-functional cold roll.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of multi-functional cold roll, comprise roll mandrel, on roll mandrel, be provided with a pair of axle collar, the circumferential surface of the axle collar is fixedlyed connected with the groove piece, axle collar center is connected with roll mandrel by positioning key, and the pass of the descending variation of one or two radius is arranged on the circumference of groove piece.
According to another embodiment of the present utility model, comprise that further the circumferential surface of the groove piece and the axle collar is connected by bolt.
According to another embodiment of the present utility model, comprise that further the groove piece is connected by long key with roll mandrel.
The beneficial effects of the utility model are: this multi-functional cold roll, can a disposable rolling pipe, and also can disposable rolling two tubes, simple in structure, saved raw material, reduced cost of manufacture, improved production efficiency.This roll also has compactness, the simple in structure and advantage of flexible type not, and is easy to operate.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the schematic diagram of an embodiment of the present utility model;
Fig. 2 is the schematic diagram of another embodiment of the present utility model;

The specific embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
As Fig. 1 is the schematic diagram of an embodiment of the present utility model, a kind of multi-functional cold roll, comprise roll mandrel 1, on roll mandrel 1, be provided with a pair of axle collar 2, the circumferential surface of the axle collar 2 is fixedlyed connected with groove piece 3, the axle collar 2 centers are connected with roll mandrel 1 by positioning key 4, the pass that a descending variation of radius is arranged on the circumference of groove piece 3. the circumferential surface of the groove piece 3 and the axle collar 2 is connected by bolt 5, groove piece 3 is connected by long key 6 with roll mandrel 1, can guarantee that like this groove piece 3 rotates synchronously with roll mandrel 1. when cold pilger mill is worked, starter motor, drive unit rotates by gear driven roll mandrel 1, and the groove piece 3 that is positioned roll mandrel 1 surface also rotates with roll mandrel 1, up and down two synchronous backwards rotation of roll, by a pair of corresponding pass that pipe is molded, this operation can pipe of disposable compacting.
As Fig. 2 is the schematic diagram of another embodiment of the present utility model, a kind of multi-functional cold roll, comprise roll mandrel 1, on roll mandrel 1, be provided with a pair of axle collar 2, the circumferential surface of the axle collar 2 is fixedlyed connected with groove piece 3, the axle collar 2 centers are connected with roll mandrel 1 by positioning key 4, and the pass of two descending variations of radius is arranged on the circumference of groove piece 3.The circumferential surface of the groove piece 3 and the axle collar 2 is connected by bolt 5, and groove piece 3 is connected by long key 6 with roll mandrel 1, can guarantee that like this groove piece 3 rotates synchronously with roll mandrel 1.When cold pilger mill is worked, starter motor, drive unit rotates by gear driven roll mandrel 1, the groove piece 3 that is positioned roll mandrel 1 surface also rotates with roll mandrel 1, two synchronous backwards rotation of roll up and down, by two pairs of corresponding passes that pipe is molded, this operation can disposable compacting two tubes.
As Fig. 3 is the schematic diagram with groove piece of a pass, the pass that a descending variation of radius is arranged on the circumference of groove piece 3, the circumferential surface of the groove piece 3 and the axle collar 2 is connected by bolt 5, groove piece 3 is connected by long key 6 with roll mandrel 1, can guarantee that like this groove piece 3 rotates synchronously with roll mandrel 1.
As Fig. 4 is the schematic diagram with groove piece of two passes, the pass that two descending variations of radius are arranged on the circumference of groove piece 3, the circumferential surface of the groove piece 3 and the axle collar 2 is connected by bolt 5, groove piece 3 is connected by long key 6 with roll mandrel 1, can guarantee that like this groove piece 3 rotates synchronously with roll mandrel 1.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
