Abstract
The utility model belongs to the field of machining, and relates to cold tube rolling devices, in particular to a three-roller cold tube rolling device. The three-roller cold tube rolling device is used for solving the problems that due to the fact that semifinished products are in a supporting-free state all the time in the feeding process of an existing rolling mill, the semifinished products are prone to bending and deformation, and product quality is affected. A feeding supporting mechanism is installed on a working platform between a feeder and a working portion shell on a machine tool body. The feeding supporting mechanism comprises a plurality of rotating shafts and a plurality of supporting rollers. The rotating shafts are arranged below a tube to be cold rolled in parallel side by side in the length direction of the working platform. Each rotating shaft is sleeved with one supporting roller. The outer side face of each supporting roller is provided with a second arc-shaped concave face matched with the outer side face of the tube to be cold rolled.
Description
Technical field
The utility model relates to a kind of cold rolled tube device, more specifically, relates to a kind of three roller cold rolled tube devices, belongs to field of machining.
Background technology
Cold pilger mill is to utilize annular distance shape hollow forging to be carried out to the process equipment of cold conditions rolling, these facility have good cogging performance, also non-ferrous metal seamless steel pipe that can rolling general precision, the feature of cold pilger mill maximum is that stock utilization is high, and precision and surface roughness are all better than drawn tube.Existing cold pilger mill is divided into two kinds, LG type and LD type, and the cold-rolling mill of LG type is two-roller mill, and the cold-rolling mill of LD type is multi-roll mill, but these two kinds of milling trains are in feeding process, blank, always in non-matted state, causes blank easily to occur bending and deformation, and affects product quality.
Utility model content
In view of this, main purpose of the present utility model is to provide a kind of three roller cold rolled tube devices, can solve existing milling train in feeding process, and blank, always in non-matted state, causes blank easily to occur bending and deformation, and affects the problem of product quality.
For achieving the above object, the technical scheme that the utility model is taked is: the utility model comprises machine tool main body, feeder and drive motors, machine tool main body is horizontally disposed with, feeder and drive motors are arranged on the right-hand member of machine tool main body, the clutch end of drive motors be connected with the power intake of feeder, the utility model also comprises three cold rolls, three cold rolling roll shafts and feeding supporting mechanism, three cold rolling roll shafts are in the operate portions housing that equilateral triangle is arranged on machine tool main body, each cold rolling roll shaft cold roll of each suit respectively, on each cold roll lateral surface, be respectively equipped with and the first arc-shaped concave for the treatment of that cold rolled tube lateral surface matches, a circle of four the first arc-shaped concave compositions, described feeding supporting mechanism is arranged in machine tool main body on the workbench between operate portions housing and feeder, described feeding supporting mechanism comprises multiple turning cylinders and multiple backing roll, multiple turning cylinders are set in parallel in the below for the treatment of cold rolled tube side by side along the length direction of workbench, backing roll of the each suit of difference on each turning cylinder, the lateral surface of each backing roll is equipped with and the second arc-shaped concave for the treatment of that cold rolled tube lateral surface matches.
Compared with prior art, the utlity model has following beneficial effect: the utility model adopts three cold rolls to carry out cold rolling to blank, can there is the fineness that ensures to greatest extent product appearance, by multiple backing rolls are set on workbench, blank can not be occured bending and deformation in course of conveying, because the outer surface of each backing roll is provided with the concave surface matching with blank, therefore, can effectively ensure that blank surface can not be out of shape, and keep the fineness of blank outer surface, the utility model is simple in structure, cheap, its manufacturing cost is only 1/3rd of existing three roller LD type cold-rolling mills.
