Be simply described as follows about manufacture method of the present utility model: see also shown in Figure 16 to 18.

1. at first cast a metal shell 80 with dewaxing process.

2. make two guide bars 81 with copper or aluminium or stainless steel or other metal, the length of this two guide bar 81 is long than housing groove 82 degree of depth, and this two guide bar 81 is located at groove 82 diapires, and guide bar 81 will protrude out housing 80 outer predetermined lengths.

3. housing 80 is placed the die cavity 84 of a bed die 83.

4. will contain the made group of epoxy resin dipping material 85 ' place groove 82 by carbon fiber wire.

5. plate 86 is set on guide bar 81 and is positioned at material a 85 ' top.

6. backform 87 is placed plate 86 tops, backform 87 also has guide hole 88 and wears for guide bar 81, as shown in figure 16.

7. mould is inserted in the hot press pressurized, heated diplomatic corps material 85 ' harden into fiber-reinforced resin to hit layer 85, as shown in figure 17.

8. housing 80 is taken out in die sinking, with protruding out the guide bar 81 of plate 86 tops ' excise or polish, slightly gives trimming again, promptly obtains a bar head as shown in figure 18.

Again as shown in figure 19, plate 90 can be cooked as thin as a wafer, and punching out becomes concaveconvex shape, to form duct 91.Because plate 90 main purposes are to form a wear-resisting protective layer, then still hit a layer structure as for the stress of batting and bear, so the thickness of plate all can as long as be shaped as in duct and the unlikely scope of breaking in the energy punching out by fiber-reinforced resin.Because plate can be cooked as thin as a wafer, high as the titanium cost so the raw material that can simplify most forms protective layer at the bar head scope of attack, cost moulding that then can minimum with the utility model has the bar head of the titanium scope of attack.Again because of plate is thin, in light weight, so unlikely increase bar head batting surface weight is convenient to the down design backward of the nose heave heart of bar.

The guide bar that the advantage of this manufacture method is to be convexly equipped with housing is directly for plate and backform location, abandon the mode of existing guide pins in order to top, bed die and hole opposition, no matter therefore between metal shell and bed die depression great clearance error is arranged, during because of the backform matched moulds, plate is subjected to the guiding of guide bar will be down to very accurately the slot opening end, so the frame of product will very all claim. More be directed to the slot opening end because the plate of this manufacture method energy is point-device, so the shape of this plate reaches It is very identical with the slot opening end that big I is done, and need not to stay bigger admissible error again, makes product in appearance more attractive in appearance.

The utility model characteristics are the one-body molded duct of sheet metal punching press that is of close texture through calendering; again this thin slice is located at the fiber-reinforced resin substrate surface; make the sclerosis of fiber-reinforced resin basic unit form the agent structure of bar head batting surface through pressurized, heated; utilize this sheet metal coating to protect this agent structure surface, make this basic unit avoid wearing and tearing. Bar head of the present utility model is because batting mask coat of metal; and below this coat of metal, there is the splendid basic unit of resistance to impact and elasticity to form back-supported; therefore the duct of this bar head can wear and tear hardly; so can make the bar head outside having the good advantage of composite bar head batting elasticity, can exempt the not wear-resisting shortcoming of composite bar head simultaneously. Again in light weight because of this sheet metal, material usage is economized, thus can not affect the nose heave heart design of bar, and can minimum cost obtain splendid quality. Because its duct moulding is easy, the manufacturing formality is simple, so can the high-quality bar head of low cost fabrication again.
