る。(Prior Art) Generally, a tube of a heat exchanger such as a parallel flow type is formed by extrusion molding and has a single or a plurality of refrigerant channels inside. A series of tubes formed by this extrusion molding are wound around a drum, and the tubes fed out from the drum are cut into a predetermined length by a cutting section. Note that the vertical and horizontal dimensions of the tube are shaped in the steps before and after cutting.

264218号）方法が採用されている。 Conventionally, in order to cut a tube of a predetermined length, a metal saw cut, press cut, laser cut, or a blade attached to a roller is rotated to create a groove, and then tension is applied in the direction to open the cutting groove. (For example, JP-A-63-
264218) method has been adopted.

程が必要となり、工程数が増加し、コスト高を招
くという不都合があつた。(Problem to be Solved by the Invention) However, in the above case, since the tube is cut by cutting with a metal saw, chips such as chips are generated and adhere to the tube, or the cut surface of the tube is Since burrs are formed and the openings are partially blocked, steps of removing chips and deburring are required, which increases the number of steps and increases costs.

が生じた。 In addition, in the above method, since the tube member is cut by the press cut blade, the opening shape of the cut surface is distorted or crushed and deformed.
Since burrs are also likely to occur, a step of removing burrs or expanding the opening is required, resulting in an inconvenience of increased costs.
また上記は、レーザーの熱的溶解によつて部

あつた。 In addition, in the above method, because the parts are cut by thermal melting with a laser, some parts of the parts become welds and adhere to the tube, so a process for removing them is required, which increases costs. There was an inconvenience.

合でもコストが増大する不都合があつた。 Furthermore, in the above method, grooves are created in the tube by rotating a blade attached to a roller, so
When used to cut flat tubes, the blade sinks into the tube when making grooves, creating burrs as in the case of press cutters, which may partially close the passage. Also, when cutting,
Since tension is applied by rollers in the transport direction of the tube and the tube is torn at the groove portion, the end surface of the tube opposite to the groove forming portion will be torn off while stretching, and as a result, the opening end surface will not be flat. However, a step of preparing the end face is required, and even in this case, there is a disadvantage that the cost increases.
そこで、本発明では、切屑、バリ、溶着物の除

The object of the present invention is to provide a tube manufacturing method that makes it possible to reduce manufacturing costs.

されている。(Means for Solving the Problems and Their Effects) The method for manufacturing a tube for a heat exchanger of the present invention includes a tube member of a predetermined length that has a refrigerant flow path formed therein by extrusion molding and is continuously fed. A method of manufacturing a tube of a heat exchanger to obtain a tube, wherein a cutting blade is formed on the periphery and a rotatably supported disc cutter is used to cross the upper and lower walls of the tube member to cut both sides of the tube member. A groove is formed in the wall portion, and then, while the upstream side of the groove of the tube member is fixed, the downstream side of the groove is swung from the groove as a reference point, thereby breaking the tube member at the groove portion and obtaining a single tube. It is said to be composed of

したり開口を拡管する工程が不要となる。 Next, the tube member 6 reaches the separating portion 4, and a set of two disc cutters 16a, 16 are inserted into the groove forming portion 13 at the cutting position of the tube member 6.
b moves in a direction perpendicular to the feeding direction of the tube member 6 while sandwiching the tube member 6 from above and below. At this time, since the dimension between both cutting edges is set to be narrower than the tube height B, and each disk 16a, 16b is rotatably supported on the spindle, both disks 18a, 18
b sinks into the upper and lower walls of the tube member 6 and crosses it while rotating, thereby forming grooves 15 in the upper and lower walls of the tube member 6.
In this case, the depth of the groove 15 is set so as to stay within the thickness C of the upper and lower walls of the tube member 6 at the maximum. Therefore, since the disk cutter is bitten and is moved while rotating from itself,
Unlike the conventional method, the grooves are formed in a tearing manner, so chips, burrs, etc. are not generated, and there is no need to remove them or expand the opening.

2a and 22b, and the downstream side is gripped and fixed by the clamp members 23a and 23b of the swinging section 21, and the clamp member 23 of the swinging section 21
a and 23b swing in an arc around the groove 15, for example, by one reciprocation. As a result, the tube member 6
is broken at the groove 15 portion, and a single tube of a predetermined length is obtained. In this case, tube member 1
Since grooves are pre-formed over almost the entire thickness of the upper and lower walls of 6, it can be easily broken, and the flow passage opening at the broken part will not be blocked, resulting in a tube with an orderly opening. It will be done.

After completing processes such as drying, the heat exchanger is manufactured by assembling and integral brazing in the assembly process. In this way, it is possible to omit various processes for preparing the opening and end face of the tube alone, thereby reducing manufacturing costs and improving economic efficiency.

簡素化が図られ、コストの低減を図ることができ
る。(Effects of the Invention) As explained above, according to the present invention, when cutting a groove on a tube member, the disc cutter rotates from itself and sinks into the outer wall of the tube member and cuts across it, so it does not burr like press cutting. Also, unlike metal saws, no chips are generated. When obtaining a single tube, the tube member on the downstream side of the formed groove is swung around the groove and is broken along the groove to separate the tube, so that the opening shape is not damaged. Since the opening and end face of the resulting tube become well-ordered, it becomes possible to omit the conventional complicated processes such as removing welded materials, expanding the opening, and adjusting the end face, simplifying the manufacturing process. This makes it possible to reduce costs.

器のチユーブの製造方法。[Claims] 1. A method for manufacturing a tube of a heat exchanger, in which a tube of a predetermined length is obtained from a band-shaped tube member in which a refrigerant flow path is formed inside by extrusion molding and is continuously fed. By cutting across the upper and lower walls of the tube member with a rotatably supported disk cutter having a cutting edge formed thereon, a groove is formed in both wall portions of the tube member, and then, a groove is formed on the upstream side of the tube member. A method for manufacturing a tube for a heat exchanger, characterized in that the tube member is fixed at the groove and the tube member is broken at the groove portion by swinging the downstream side of the groove using the groove as a reference point to obtain a single tube.
