However, because of the complicated manufacturing process, the cost is very high and cannot be reduced. In the current welding method, there are various operation methods for the welding method. Basically, as long as the welding equipment is stable, the machine function is selected correctly, and there is no great difficulty in the welding process. However, the big technology and the bottleneck are the design of welding fixtures, especially the thickness of welding-type waves, and the thickness is only 0.1mm, so the quality of welding fixture design directly affects the welding quality and production efficiency. Read from my brother-two pictures to understand the basic structure of the bellows, the bellows is composed of a plurality of disc-shaped diaphragms i connected in series, each disc-shaped diaphragm 1 has a-ring It is ring-shaped and defines a perforated central portion 11 and an annular peripheral portion extending outward from the outer periphery of the central portion U, and the horizontal position of the peripheral portion 12 is higher than that of the central portion. See the second and fourth illustrations for the following picture: “A potential method using a disposable ring sheet ^” The joining procedure of the material-connected bellows is cut—the disposable ring sheet is placed between two adjacent diaphragms 1, and then In two diaphragms! The central part of η == is connected to make a diaphragm group 2, and finally the plurality of diaphragms: group 2 012 are welded to form a corrugated tube with a certain length. However, the positioning of the disposable ring piece 31 in the diaphragm 2 requires time-consuming adjustment, and 200416082 (2), invention description (2) cannot be taken out directly after welding, and it needs to be cut and damaged. Therefore, it belongs to the disposable method, and it is easy to hurt the diaphragm 丨 the body ′ during the removal process, so the cost is very high. Referring to the fifth and sixth figures, for a method for manufacturing a corrugated tube 5 using a c-shaped ring piece 32, firstly weld the center portions 11 of two diaphragms 1 together so that the peripheral portions 12 of two adjacent diaphragms 1 cooperate and define A clamping space 20 is produced, and then the c-shaped ring piece 32 is placed in the clamping space 20 and welded and tightly sealed to form a diaphragm group 2 as shown in the sixth figure. The peripheral portion 12 of the sheet group 2 is welded to form a corrugated tube having a length. When the c 10-shaped ring piece 32 is placed in the clamping space 20, the C-shaped ring piece 32 needs to be opened two times first; after being inserted, the sin itself returns to true roundness, so the large diaphragm is being manufactured. In group 2, because the relative opening amount is not large, it is still in the range of elastic strain. For the small externally controlled diaphragm group, because its opening amount is relatively large, it is easy to exceed the elasticity of the elasticity and cause deformation and formation. Non-true circle state. When combined, the protrusions of the 15 parts of the circumference will be different, which will affect the welding quality. The seventh picture of the tea reading is a m1 production method using two half-ring pieces 33 to form a square. Although this method can obtain a true circle, the disadvantages include: a. The production cost is high. One circle must be cut in half with two circles to use ° b • Circle cutting. Due to its internal stress, there will be deformation. c. What's wrong? Use the discarded ring sheet 31 'in the third picture or the one in the fifth picture (:: type% piece 32, or the two half of the seventh picture 81¼ piece 33) It belongs to the gap clamping method of the positioning ring piece 3. However, when the above-mentioned corrugated tube outer diameter gap lost welding method is used to actually manufacture the wave 200416082 发明, the description of the invention (3), the corrugated tube also needs to cooperate with the center mandrel 25. Clamping and positioning, then pressing and clamping by the tail end of the corrugated tube, and finally welding a plurality of adjacent two peripheral portions 12, 12 belonging to different diaphragm groups 2, 2 'with a welding gun 26, welding, Finish the production of the bellows. Before the bellows is pressurized and clamped, a special special fixture is needed to position the above-mentioned position retaining rings 3 in order to obtain the protrusion of the peripheral portion 12 of the diaphragm] The two end surfaces of the positioning ring pieces 3 need to be flat to be able to adhere to the plane of the diaphragm i to achieve the effect of heat transfer and dissipating heat. 10i The materials used for the positioning ring pieces 3 also need to consider elasticity. And heat transfer efficiency. Therefore, it is difficult and costly to produce, and The length of the bellows is limited, and it needs to be assembled once, which is not easy to be segmented. Because the diaphragm group 2 is matched with the positioning ring 3 depending on the required length one = enter the central mandrel 25 'and then press the pressure to make the diaphragms ！ It is in close contact with these positioning ring pieces 3 and 15. If the assembled length is too long, it is difficult to apply pressure evenly. If the pressure is too small, the part is not close enough and it is easy to form a gap. When the pressure is too large, it is easy to cause this. The positioning ring piece 3 and these diaphragms! Damage, or the protruding part is opened and turned into a gap, which is very difficult to make. Therefore, improving the production difficulty of the bellows and reducing the cost of production 20 'becomes The primary problem to be improved by the present invention is to provide a method for manufacturing a bellows which is easy to manufacture and has high welding quality. In addition, another object of the present invention is to provide a method These diaphragms, the description of the invention (4) a series of corrugated tube diaphragm forming devices for clamping, positioning, and even heat transfer required by the outer t welding day guards 5 10 15

The forest gun το 8 is located at the periphery of the first clamping mold 6 and the second clamping mold 7. 10 15 Referring to the fourteenth figure, when the first and second clamping portions 611 and 611 of the first and second clamping molds 6 and 7 are moved into the adjacent two diaphragm groups along the radial direction, respectively When the clamping spaces 413, 413 in 4, 4, and are displaced toward each other along this axis, the adjacent diaphragm sections 412, 412 'adjacent to the two diaphragm groups 4, 4, can be clamped. And at this time, the outer peripheral surfaces of the first and second clamping portions 711 cooperate to define—a recessed annular groove 9, and the two peripheral portions 412, 412 being clamped, and partially protruding in the annular groove ^ For the flare gun unit 8 to perform peripheral welding processing on the peripheral portions 4l2 and 4i2 so as to weld them together. When the welding torch unit is formed, the inner surfaces of the first clamping mold 6 and the second clamping mold 7 = 61, 71 are against the outer peripheral surfaces of the diaphragm group surrounding portions 412, 412 '. Referring to the fifteenth figure outside, when two adjacent diaphragm groups 4, 4 and adjacent two or two surrounding portions 412, 412 'are welded together by the welding grab unit 8, the brother-and the first The first and second clamping portions 611 711 of the two clamping molds 6 and 7 move out of the adjacent two cymbal groups 4 and 413 and 413 in the direction of the line control, and continue to move in The clamping space 413, 413 of the next two adjacent diaphragm groups 4, 4 'is used to repeat the welding operation. 20 200416082 发明, invention description (9)' In this way, the bellows with a certain length can be made. . Although the diaphragm set 4 series connection forming device of the bellows of the present invention adopts a combination of two semicircles in appearance, the rigidity of the overall fixture is strong, and there will be no distortion and roundness distortion, and the first of the series connection forming device Clamping molds 6 and 5 The overall quality of the second clamping mold 7 is large, and it has a good ability to absorb heat, and the temperature field formed is stable, and the quality of the weld bead is relatively uniform. The first clamping mold 6 and 5 The second clamping mold 7 uses the valley spaces 413 and 413A of the diaphragm groups 44 as the clamping positions, and when the combination welding is performed, the positioning mandrel 5 is used as a positioning combination reference, and a group of welding beads are welded at a time. Therefore, the assembly time is extremely fast, and no additional positioning and clamping adjustments are required. Moreover, the protrusions of these peripheral portions 412, 412, are uniform during welding, and the positioning ring piece 3 as conventionally known will not occur. The protrusion amount varies due to deformation of the positioning ring piece 3 or poor positioning and assembly. phenomenon. 15 In summary, the method for manufacturing a bellows according to the present invention, and the cascade forming device of the diaphragm group 4 of the corrugated officer, in addition to the positioning requirements of the diaphragm group 4, the annular groove 9❸ is designed and has a dispersive absorption of the special unit. 8 = Excessive input heat to avoid the function of excessive melting, and completely avoid the shortcomings of the Qishu driving know-how, making the bellows more suitable for production costs, easier operation, and better in production. The welding quality, it can indeed achieve the purpose of the present invention. Those mentioned in quasi-X are only the preferred embodiments of the present invention.
