[Prior art] The oval tube is used in, for example, a gas heater. The advantage is that the area of the outer surface of the tube and the amount of liquid in the tube are increased, and compared with the use of circular tubes, it is between the tubes. There is a more favorable gas flame cycle. A conventional oval tube is formed by forming a sheet of material into a u-shaped profile, and then welding the seams on the sides of the profile to close the tube. It is also possible to stretch the tube through an oval ring and use molding techniques to make an oval tube. When rolling an oval tube by rolling a circular tube, it is possible to leave marks along the entire length of the tube on the sides of the tube, on the seams of the top and bottom rollers, this mark is harmful to the tube Appearance and required characteristics. In addition, the short radii of oval tubes are still insufficient in some cases. From the patent publication J P 9 2 3 9 4 3 8 there is known a method for forming a circular tube into an oval tube using a rolling technique. With this invention, a circular tube can be rolled into an oval tube, so that the tube system is rolled by top and bottom rollers and two rollers on both sides of the tube. However, according to this method, the rolling force required for the side rollers is too high for the measurement required to achieve the oval tube. SUMMARY OF THE INVENTION The object of the present invention is to introduce a novel method for manufacturing a metal oval tube in order to avoid the disadvantages of the conventional technology. The characteristics of the present invention are as defined in the characteristic part 5 312 / Invention Specification (Supplement) / 93-01 / 92128078 200418587 in the independent item of the scope of patent application. The features of other embodiments of the present invention are defined by the contents of the rest of the application. With the method and device of the present invention, significant benefits can be achieved. With the method of the invention, it is possible to manufacture oval tubes by rolling in a cost-effective manner and to obtain high-quality products. According to the present invention, a substantially circular metal pipe is rolled in the transverse and longitudinal directions of the pipe, meaning that the gold pipe is rolled in at least two steps, and the metal pipe is The rolling step is rolled at least once in the direction of the rolling direction. Certainly, the total degree of deformation of the metal tube is basically 3-5%, which involves the difference in metric weight (= weight / meter) between the original and the finished elliptical tube. According to the present invention, at least two feed rollers are used to guide the metal pipe to feed the metal pipe to the rough rolling step. The feed rollers used are those that have the same shape as the metal tube to be rolled on the surface in contact with the metal tube. In the rough rolling step, the metal tube is rolled downward by using two rough rolling rollers, so that the degree of tube shape is basically 0.5-2%, so as to better present the final measurement. In some cases, the rough rolling roll is bi-radial on the surface in contact with the metal tube, and the formation of the smaller radius in the finishing rolling roll is preferably enhanced. Roll at least two sides of the metal tube in a direction perpendicular to the rough rolling direction. The metal tube obtained from the rough rolling process can be rolled by 1-8% of its width, preventing the previous rough rolling step from being at the top. And the seam joint of the bottom roller is left on the marked tube. The side parentages used are straight reporters whose surfaces are in contact with the metal tube. In addition, the side parent-child system is used to adjust the straightness of the tube in the smaller diameter direction of the oval tube, and to influence the shorter diameter shape of the oval tube. In the finishing rolling step, use at least two finishing rollers to roll the metal tube roll 312 / Invention Manual (Supplement) / 93-01 / 92128078 Large rolling 6 200418587 into an oval shape, so that the degree of deformation of the tube is basically 2-3.5%. The shape of the finishing roll basically corresponds to the oval shape at the surface in contact with the metal tube. According to a preferred embodiment of the present invention, the metal pipe is straightened by at least two bridges in at least two mutually perpendicular directions. This affects the flatness of the final oval tube. According to a preferred embodiment of the present invention, the straightening rollers used are two parent-children having a substantially V-shaped groove on the surface in contact with the metal tube, and six straightening rollers which are basically The top is uni-radial in the surface and perpendicular to the previous straightening roller. According to a preferred embodiment of the present invention, at least the rough roll and the finish roll are adjusted in both a radial direction and an axial direction. According to a preferred embodiment of the present invention, the radial adjustment is achieved by using a different adjustment mechanism to adjust the difference between the rollers. In the axial direction, adjustment is achieved by an adjustable locking plate and a ring made of pneumatic material, both of which are connected to the rollers. At least the side rollers are adjusted for shape and straightening adjustment. Through the adjustment mechanism connected to the roller, the measurement of the oval tube can be influenced, and through this mechanism, the adjustment of the oval tube of different sizes can also be performed in a fast and accurate manner. The method for manufacturing a metal oval tube according to the present invention is realized by using a device including a roller for rolling a substantially circular metal tube in a side direction and a vertical direction. The device includes at least two groups of metal tubes. The parent and child of the side, and another group of rollers on both sides of the metal tube in a direction perpendicular to the rolling direction defined by the previous two groups of rollers. [Embodiment] The present invention will be described in detail below with reference to the drawings. 1a and 1b show an apparatus for manufacturing an oval tube according to the present invention. Figure lb shows the cross section taken in the direction of arrow 23 in Figure 7 312 / Invention Specification (Supplement) / 93-01 / 92128078 200418587. A metal pipe (such as a copper pipe) of a cross-section and made of hard or soft metal is fed into the rolling device 9 so that the roller 10 which conforms to the shape of the metal pipe 11 keeps the metal pipe at a given Alignment for rolling operations. The feed can be located above or below the metal pipe, or on both sides, and on the surface 17 where the rollers are in contact, they have the same shape as the metal pipe. Feed 1 0 feeds the metal tube 1 1 into the rough rolling step 2 where the round metal tube is flattened by the roller 12 so that the tube presents the final measurements. Sub 12 is above and below the tube, and is in contact with the metal tube; on the double radial (biradial), that is, there is a radius of R1 and R2 to distinguish the rolling step 2, the degree of deformation of the metal tube 1 1 is 0.5 - 2 %. The weight difference per meter between the original tube 8 and the processed metal tube. The thickness remains substantially the same throughout the rough rolling process, but the wall is reduced. After the rough rolling step 2, the metal pipe 11 is transferred to the next step 3 in the line, where the pipe is rolled down by both sides 13 in a direction perpendicular to the rough rolling direction. The metal pipe after the rough rolling step 2 is originally On the surface 19 that is in contact with the metal pipe 11 width, the side rollers 13 are straight side rollers to ensure that the quality requirements for the oval tube in the final rolling are achieved, and in the rough rolling step, It prevents the top and bottom seam joints from leaving marks in the metal tube. The side rollers 1 3 also use the flatness of the oval tube in the larger diameter direction. In the next finishing rolling step, the metal pipe is rolled by two precision 14 located above and below the metal pipe 11, so that the metal pipe obtains an oval shape. In this case 312 / Invention Specification (Supplement) / 93- 01/92128078 For the slightly round 1 feed, feed the roll into the metal tube into the roll, two rough rolls and rough rolls, good surface 18. In the perimeter of the pipe wall, 8% of the rolls are reported. of. Make the short-radius roller to adjust 4 in the case of rolls. In the case of rolls, the 200418587 metal tube has a deformation degree of 2-3.5%. The shape of the finishing rollers 14 on the surface 20 contacting the metal tube corresponds to an oval shape. After finishing rolling step 4, the metal pipe is transferred to the straightening units 5 and 6 where the metal pipe 11 is straightened by at least two directions perpendicular to each other using straightening rollers (15, 16). This bridge reports sub-guiding and straightening tubes. The bridge straight 15 used is two rollers arranged on both sides of the metal pipe. The surface of the roller which is basically in contact with the metal pipe 11 is a V-shaped groove. Straight parent-child 16 in the rear bridge. After the straight units 5 and 6, the end product, the oval tube 7, is obtained. Fig. 2 shows how the roughing rolls 12 and finishing rolls 14 are adjusted in the radial and shaft directions. Radial adjustment is achieved by a rocker mechanism 25, which means that its housing element 26 has a groove 27 that can cause the housing element to move 27. An adjustment mechanism 28, which is arranged to be connected to the housing element, can adjust the vertical direction The distance between the middle rollers. The adjusting mechanism 28 includes a wedge 29, a wedge transfer screw 37, and a locking screw 30. When the screws should be shifted closer to each other, the locking screw 30 is opened, and the wedge 29 is shifted forward by the wedge transfer screw, and then the locking screw 30 is locked. A given distance in the movement of the adjustment mechanism 28 is a given distance in the vertical movement of the roller 14. The adjustment requirement of the system is 0-0.2 mm, which means that the difference in the parallelism of the roller axis will not interfere with the processing. In the horizontal direction, the rollers 14 are moved due to the axial adjustment. Axial adjustment is achieved by an adjustable locking plate 3 1 and a ring 3 2 (configured to be connected to the roller 1 4) made of pneumatic material (such as rubber), and by moving the plate and ring, the roller groove 3 3 It is adjusted to fit in the axial direction. FIG. 3 shows the adjustment of the side rollers 13.
