For realizing above-mentioned purpose of the present invention, the invention provides a kind of stainless steel cladding non-round tube, it is characterized in that the non-circular shape in its cross section.
The processing method that the invention provides a kind of stainless steel cladding non-round tube may further comprise the steps:
Stainless steel is cladded pipe send into the charging rollgang;
The feeding rollgang is sent circular pipe into the non-round tube milling train;
Starting the non-round tube milling train becomes the circular pipe cold rolling non-circular, vertically aligns then;
Stainless steel cladding non-round tube breaks away from cold rolling mill and enters the blanking rollgang.
Stainless steel cladding non-round tube process equipment provided by the invention comprises:
Be used for importing the roller-way of stainless steel cladding pipe raw material;
The cold rolling mill transmission device that the ratio gear distributor case such as comprises;
Above-mentioned stainless steel is cladded the rolling device that pipe is rolled;
Stainless steel after rolling is cladded the straightener that non-round tube is aligned.
The stainless steel of aligning is cladded the rollgang of non-round tube output;
Processing method provided by the invention is owing to adopted small deformation, linear deformation roll, can guarantee every time rolling deformation rate unanimity, change first big after small in the past cold rolling deformation rule, and ratio gear case such as employing, make output shaft on-stream maintenance in front and back synchronous, eliminate driving error.Adopt transmission aligning mode, the end of eliminating stainless steel non-round tube front and back thickens problem, and increase progressively bottom diameter of the roll by sortie, make roll send rotary speed and pipeline to keep synchronously, processing method of the present invention and process equipment have overcome the defective that prior art for a long time can not the compound non-round tube of processing stainless steel, have filled up a blank of the compound non-round tube forming method of cold-rolling stainless steel and equipment thereof.

Fig. 2 is die hole type profile figure of the present invention.
Fig. 3 is the structural drawing of process equipment of the present invention.
Embodiment
Fig. 1 is the sectional view of embodiment's oval pipe of the compound non-round tube of stainless steel provided by the invention.In the present embodiment, Stainless Steel Tube is the stainless steel enclosure wall tube, and its internal layer is a carbon steel, and at the stainless steel of the outside of carbon steel cladding one deck 0.1-0.4mm, the thickness of above-mentioned thickness stainless steel lining can change as requested, thereby plays antirust effect, and has gloss.
Fig. 2 is the sectional drawing of last sortie pass of process equipment provided by the invention, after Stainless Steel Tube enters milling train, is rolled into illustrated oval stainless steel composite pipe gradually.
Fig. 3 is to the schematic representation of the process equipment of stainless steel cladding non-round tube provided by the invention.
Below in conjunction with Fig. 3 the processing method and the process equipment of stainless steel cladding non-round tube provided by the invention are elaborated.An embodiment of process equipment of the present invention comprises aligning frame 1, plain-barreled roll frame 2, standing roller frame 3, gear-box 4, transfer roller 12, buffing machine 13 and guide sleeve 14.Kind to be processed is for being 40 * 22 elliptical tube from diameter for the 32mm pipe is processed into specification.Gear-box 4 and employing wait the ratio gear case, drive plain-barreled roll frame 2, standing roller frame 3 work.
Stainless steel is cladded pipe put on the charging transfer roller 121, charging transfer roller 121 makes pipe enter the introducing port 14 of milling train, promptly a kind of guide sleeve, and introducing port 14 is made up of upper frame and lower frame, and nylon jacket is housed in the upper frame.When the Stainless Steel Tube bore of being processed changes, the nylon jacket in the introducing port upper frame can be replaced with corresponding Dimensions and get final product.The first plain-barreled roll frame 21 that stainless steel cladding pipe enters milling train by the introducing port guide sleeve, the effect of this first plain-barreled roll frame mainly is the raw material of nipping, and the bore of its pass is identical with the external diameter of pipe, and promptly diameter is 32mm.The pass that makes it enter first edger roll, 31, the first edger rolls after first plain-barreled roll is nipped pipe is consistent with the pipe pass, enters milling train smoothly after pipe is nipped.Then, the pass that pipe enters the second plain-barreled roll frame, 22, the second plain-barreled rolls is to make pipe be cold rolled to major axis 36, minor axis 27, nib type figure such as Fig. 2 that it is cold rolling.Subsequently, pipe enters into the elastic return that the effect of 32, the second edger rolls of second edger roll is minimizing pipe rings, so its pass is identical with second plain-barreled roll 22, then enter the 3rd plain-barreled roll pass and make pipe be cold rolled to major axis 40, minor axis 22, nib type figure such as Fig. 2 that it is cold rolling.Subsequently, it is consistent with the pass of the 3rd plain-barreled roll 23 that pipe enters into the pass of 33, the three edger rolls 33 of the 3rd edger roll, and its effect is identical with second edger roll 32.Then pipe enters into the effect that 24, the four plain-barreled rolls 24 of the 4th plain-barreled roll are conduct location, so its major axis and minor axis are consistent with second plain-barreled roll, pipe ring then enters aligning frame 1, after the non-round tube after the aligning frame will be out of shape is corrected, exports.The non-round tube finished product enters 122 outputs of blanking transfer roller.The effect of gear-box 4 is that driving force is distributed to plain-barreled roll frame 2 respectively, aligning frame 1.
It is to be noted; what describe in the embodiments of the invention is the compound elliptical tube of processing stainless steel, still, and obviously; method and apparatus provided by the invention can be processed the steel tubing in different shapes of other various non-circular, non-ellipses equally, and its technical characteristics is obviously also in protection scope of the present invention.
