The specific embodiment
For further understanding technology contents of the present invention, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1, Fig. 2, Fig. 3, Fig. 4 and Fig. 5.
A kind of arm that is used on the lap-welding type radiator is oval heat-radiation branch pipe 1, and heat-radiation branch pipe 1 is singly taken and is contained in upper linked box pipe 5 and lower linked box pipe one side, and heat-radiation branch pipe 1 limbers 2 is that the outer is at 3 circular ports of identical platform.Heat-radiation branch pipe is welded with shutoff 4.
Matching with the annular boss 6 of perpendicular box pipe on the identical platform face in the heat-radiation branch pipe limbers of present embodiment, also plays positioning action when welding, thereby reduce the welding difficulty, and the slit that produces when eliminating butt joint strengthens bonding strength; Have bigger water channel, good heat dissipation effect, be easy to advantages such as welding.The finished product radiator has firm welding, and is corrosion-resistant, and anti-pressure ability is strong, steady quality, long service life, advantage such as good looking appearance is beautiful.
The preparation method who is used for the arm on the lap-welding type radiator comprises oval heat-radiation branch pipe punching, shaping process process, and its oval heat-radiation branch pipe is taken and is contained between upper linked box pipe and the lower linked box pipe; When oval heat-radiation branch pipe prepared, the oval limbers of subpunch became the circular port of outer at the identical platform face by the Mould Machining limbers.During the Mould Machining limbers, fix heat-radiation branch pipe, be sidelong into inner mold, be sidelong outer mold outward, mould pressurization compacting limbers is become the circular port of outer at the identical platform face from managing interior opposite side from managing interior one.
The present invention is used for the concrete processing and preparing process of radiator:
1. blanking: carry out upper linked box pipe, lower linked box pipe, oval heat-radiation branch pipe and shutoff blanking; Cuing open light handles.
2. punching: with punch press upper linked box pipe and lower linked box pipe and oval heat-radiation branch pipe are dashed and to desire to put circular hole.With punch press oval heat-radiation branch pipe is dashed a slotted eye (as shown in Figure 4).
3. shaping: carry out upper linked box pipe and lower linked box pipe flange processing formation annular boss with mould.Process is: fixing perpendicular box pipe, be sidelong into inner mold from managing interior one, and be sidelong outer mold outward, opposite side suppresses outward flanging looping boss to mould in manage.Carry out oval heat-radiation branch pipe compacting limbers with mould and become the circular port of outer at the identical platform face.Process is: fix heat-radiation branch pipe, be sidelong into inner mold from managing interior one, be sidelong outer mold outward, from managing interior opposite side mould pressurization compacting limbers is become the circular port of outer at the identical platform face.
4. joint welding: adopt electric resistance welding to weld shutoff and heat-radiation branch pipe.The circular limbers of upper linked box pipe, lower linked box pipe ring shape boss and heat-radiation branch pipe is aimed at, adopted electric resistance welding to weld.
After joint welding is finished, polish, applied voltage test, surface treatment and preservative treatment, spraying and baking operation obtain corrosion-resistant, anti-pressure ability strong, steady quality, long service life and beautiful radiator attractive in appearance.
