Description of the invention (1) [Application fields in the industry] The present invention relates to an intake manifold for an engine for an automobile. 'Gong 丨 Engine and Diesel for Automobiles [Knowledged Technology and Issues] As shown in the sketch map used by gasoline engines of Baizhizhi Automobile, multiple branch pipes are constructed, as shown in Figure 5, to connect to One end of the engine is connected to the flange, so that flail: f The other Chinese-foreign-end is connected to the case where the model of the casting model is divided into two times, the degree of freedom becomes smaller, and because of the caster: i rod Tube = a kind of problem, the pipe made of Ming alloy is used to branch the tube; ^ zhi 'is to solve this tube 5 3 both ends are welded in the furnace to 4 rolls of Ding bow processing, the branches in this way constitute SGi :; thing ;: : General groove 52 and flange 51, 4-350353. … Uncovered in the Japanese Patent JP-A: By making a branch pipe M welded to the flat pressure groove 52 and the flange in the furnace, it can be mass-produced with excellent airtightness of the joint: 疋 在Furnace welding needs to be heated in a high-temperature environment to weld and melt the material for joining. Therefore, the thermal capacity of the parts to be joined ^ will cause thermal deformation. For example, the flat pressing shown in the enlarged section of Figure β The grooves 52 cause positional deviations in the welded portion 54 of the branch pipe 53 and the reduction of the f function is a problem. In addition, the branch pipe 5 3 is made of aluminum alloy because it is placed in a furnace under high temperature ambient gas. And aluminum castings

Description of the invention (2) The Γ11 pressure groove 52 and the like become blunt, resulting in a decrease in the strength of the material, and there will be a problem of insufficient strength. ] Qi i 发 = Known technology, ask? 'The purpose is to provide air permeability, which can be suppressed ^ ~ The use of welding in the furnace to ensure higher airtight effects to prevent positional deviations, etc., and can; guarantee; installation strength of 3 pieces, etc.' The first gist is an improvement The air flange on the engine side flange, and another one of them to join Bayi 钿 to the above-mentioned single cranial broadcast 4 i and then a to the tank chamber side of the flat pressure groove; Eight T above the 1000 pressure groove is divided into The branch pipe is riveted and positioned by riveting jigs, etc. in the above-mentioned points; and the non-heating side members are not welded in the furnace 1 to be welded to the above-mentioned welding side members. ~ Join 'uses bolts or the like to connect with each other. The second gist is to reinforce the member without reinforcement. ",,,,,,,,,,,,,,,,,,,,,,,,,: ,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,-,,,,-,,,-,-,- In the second example of the flat pressing sample, which is connected to the groove member 1 and the non-heating side member 2, the welding gutter = is cut into a welded side structure and a melting point aluminum casting alloy is formed, and the inner wall part a is constructed, for example, with a high hole lc The outer peripheral portion lb of lc and the inner wall portion 3 are formed with screw picking openings ld, ld, ld, and ld around the periphery, as shown in the expansion of FIG. 2: 4 large cross-sections are formed at intervals of θ. Opening V. Description of the invention (3) — Proximity i: Open V to have a protruding opening 1-e that is a-body protruding in the opening = :, insert one end of the branch pipe 3 controlled by Ming from the outside, from In the branch pipe 3 of the second pipe 3, 'using the riveted ㈣ state to put into Λ S 突 Λ1' for exact positioning, this type of welding is used, because the losing name 输 is the official-between the end and the opening protrusion le The length becomes connected for positioning, so the gap between the welding part and the welding = set-will not cause a position shift in the conventional way, Welding is performed in a furnace with air-tightness. Yang seconds τM uses riveting clamps outside of the second branch. The structure shown in Figure 2 of the 2 joint is the same. After the positioning, the welding in the furnace can be performed to ensure that the joint is equal to the inner member. For example, the inner wall can be faced. T is formed with bolt holes matching the bolt holes 2 of the non-heating side member 2 =] members ... tired bolt holes lc, lc; in the welding side member, the member 2 can be a solid body. Because the non-heating side member 2 is in ? The same shape of the flat pressure heating, so you can confirm the SC column 5 and so on. "Combined for strong installation" = In addition, by this way divided into _ & for the 妾 side structure and non-heating side 88122512.ptd Page 7 V. Description of the invention (4) Component 2 does not need to use neutrons. It can be used in the furnace. The branch pipe 3 in the furnace is connected to the welded side as early as in the structure. The grain volume is divided to become smaller, because the position of the welding side member pipe 3 when it is welded in the furnace Deviations, Jie made known〗 contact member and the side branch may be previously caulked by the caulking jig set k ^ In the present example, since the position deviation suppression. 3, the second embodiment is shown. Fig. 3 shows the second embodiment. The welded side member 1 of the flat groove at one end of the figure is shown by the enlarged branch root pipe 3, and the inner wall portion 1 a & As shown in the cross-section of FIG. 4, each opening is formed; each opening protrusion] e, most of the openings 1 e, 1 e can be exhausted, and riveting is performed. Welding in one end of 3, i Z + ordering position 'is placed in the furnace after riveting and positioning; r is known to be connected, and it is surely inhibited = double entry into the furnace to ensure good air tightness. Evil, using welding in the furnace to additionally use 3 ^ in each branch camp, the same use of rivets: =; flange 6 joints welding line welding, there can be no position to print and position in the furnace Into the above-mentioned welding side embossing] joining fine to ensure air tightness. The top of the non-reliable member 1 of the external entity is put into the furnace through bolts 4, 4 and fixed together :: structure: 2 Strength, according to this] strong mounting pillars 5 such as bolts.

In addition, since the non-heating side member 2 does not need to be connected to 88122512.ptd page 8 491928 V. Description of the invention (5) Heat treatment, so low-refining point alloys can be used to manufacture them cheaply [Effects of the invention] The present invention is a The intake manifold has a plurality of branch pipes which are respectively connected in the furnace so that one end thereof is connected to the flange on the engine side, and the other end is connected to the flat pressure groove on the tank side; ;: Into the following: welding, side members, in the above-mentioned branch pipe is riveted positioning such as riveting fixture f 'in the furnace feeding and joining, and the non-heated side is = screw bolts and other used to communicate with the above The welding side members are combined; because the flat pressing 2 is cut into two halves, you can put the center from the inside of the welding side member and use the riveting #clamp to place the welding side structure into the rivet riveting position, and then put it into the frying 1 and s The interface is equipped with pre-developed normal crushing joints, and can be welded in an oven. In addition, the non-heating side members are also known to be formed by aluminum casting. In addition, they are formed by the low-melting point aluminum alloy described above. . The piece 1 is a reinforcing structure for mounting non-heating components such as flat grooves. The female component that does not reduce the material strength does not need to be placed in the furnace. Therefore, it can be used to reinforce the structure.
