Description
Technical field
The present invention relates to a kind of titanium alloy process technology, particularly a kind of welding method and foundry goods thereof of the titanium alloy golf club head with self-fusing edge.
Background technology
At present, golf club has substantially all adopted titanium alloy structure, and the design of golf club becomes increasingly complex, and wall thickness is more and more thinner, and this has just caused a lot of technical problems to foundry engieering.
The golf club scope of attack is also referred to as Face, in nearly 3 years, most of titanium alloy golf club head Face structure has all become the structure of self-fusing edge, this structure has replaced the hand charge action in the welding process, make job standardization, significant superiority is arranged, 70%～100% shrinkage cavity appears when but this structure is ground after welding, cause the repair welding phenomenon, caused bad problems such as concavo-convex during repair welding again, caused the ratio of scrapping high, this phenomenon is perplexing bulb manufacturer both at home and abroad always, carry out some relevant improvement tests during this period, all do not had effect; In addition, because of the restriction of welding equipment and technical conditions, a part of titanium alloy process unit can not cancel the structure of self-fusing edge always, carries out the improvement of technology for adapting to this kind structure needs.
Prior art relates to two aspects, it at first is the welding aspect, how present golf club sparetime university all adopts the welding manner of MIG/MAG is the combination that the beam pulse welding manner carries out the Face face, and the difference of each producer of this mode is exactly the condition control of welding, but in all producers, all welding bead evenly there is requirement, and can reaches a stable degree; When adopting argon arc welding to be the TIG welding in the welding of not using MIG/MAG, the width of its welding bead is wideer; Moreover be exactly the casting aspect, the design of golf club becomes increasingly complex, and wall thickness is more and more thinner, and widespread distribution is partial to 0.6mm between 0.6～1.0mm at present; And its surface area is also increasing, and the less effect that does not have feeding of dozzle has increased bad on the contrary, dozzle causes concavo-convex again when big, so the Face self-fusing edge only depends on main cast gate to carry out feeding, at metal freezing in theory, the structure of this self-fusing edge must cause shrinkage cavity to exist.
Therefore, be to adapt to the Welding Problems of self-fusing edge structure, need the titanium alloy golf club head welding method of a kind of new self-fusing edge of design, to improve corresponding processing technology.
Summary of the invention
Technical problem to be solved by this invention provides a kind of welding method and foundry goods thereof of the titanium alloy golf club head with self-fusing edge, after solving existing technology and causing Face face combination to be ground, the ratio height that shrinkage cavity leaks outside, thus need repair welding once more, problems such as causing that weldering is recessed, weldering is broken etc. and scrap.
For the purpose that realizes solving the problems of the technologies described above, the present invention has adopted following technical scheme:
A kind of welding method of the titanium alloy golf club head with self-fusing edge, it is characterized in that: reserving at the body part of titanium alloy golf club head foundry goods highly is the self-fusing edge of 1.0～1.4mm, the width of self-fusing edge and the handing-over of bulb body is 0.2～0.5mm, the R angular breadth of golf club outer surface and self-fusing edge handing-over is 0.5mm, and the welding forging that the self-fusing edge that uses and be with the titanium alloy golf club head of self-fusing edge adapts welds, weld width during the MIG/MAG electric welding is not less than 4mm, and the control electric current makes the through welding amount reach 1.3～2.5mm.
A kind of titanium alloy golf club head foundry goods that is used to the welding method of the titanium alloy golf club head of self-fusing edge, be characterised in that reserving at the body part of titanium alloy golf club head foundry goods highly is the self-fusing edge of 1.0～1.4mm, the width of self-fusing edge and the handing-over of bulb body is 0.2～0.5mm, and the R angular breadth of golf club outer surface and self-fusing edge handing-over is 0.5mm.
Because at present the mould of golf club all is the mould that the cnc machine tool more than 3 mills out, precision can reach+/-0.01mm, as long as the CAD of die sinking tool figure shelves setting range is no more than the bound of demand, can satisfies size and set demand.Like this, just can reserve at the body part of golf club mould in the time of processing mold highly is that 1.0～1.4mm, width are that 0.2～0.5mm, R angular breadth are the unnecessary zone of 0.5mm, like this, when casting, can form the self-fusing edge that needs; At this moment, the width dimensions scope of self-fusing edge and body part interface portion can be 0.7～1.0mm, as long as can satisfy the condition that the strength demand of casting can satisfy welding remelting shrinkage cavity.
The titanium alloy golf club head welding method of band self-fusing edge of the present invention, self-fusing edge has played the effect that replaces welding wire in welding process, makes solder compositions identical with the body composition like this, reduces the aberration of postwelding.
The titanium alloy golf club head welding method of band self-fusing edge of the present invention, welding process is as follows: the scope of attack panel of getting a forging, material is the metal material of steel system or titanium system etc., it is embedded in the Face face frame of the titanium alloy golf club head of being with self-fusing edge, clamping is to the anchor clamps of MIG/MAG welding machine then, adjust and forge the gap that the scope of attack cooperates with the bulb body, make it consistent with the track of welding gun action, the size of the device current of producing according to different manufacturers and the relation of through welding amount, switch power supply is adjusted electric current, start beginning welding automatically, when moving, solder joint melts away the self-fusing edge of corresponding position, make and forge the scope of attack and body fusion, also will cast the self-fusing edge shrinkage cavity remelting that produces simultaneously.
The present invention combines with the metal contracts theory by the practical structures of self-fusing edge, thinks that the possibility that shrinkage cavity occurs is 100%, and is unavoidable; A kind of technical scheme is, after the concrete size of self-fusing edge need be made amendment, the shrinkage cavity of self-fusing edge can be guided on the self-fusing edge or near self-fusing edge, and not on body; Also having another kind of technical scheme is on body, allows its welding back grind not come out.The present invention is by guiding to shrinkage cavity near behind the self-fusing edge, use the mode of shrinkage cavity remelting can solve the problem of shrinkage cavity when welding, the concrete geomery by the design self-fusing edge appears in the welding bead of welding shrinkage cavity, during welding the remelting feeding shrinkage cavity, making does not have after the grinding shrinkage cavity to produce.
R angle part width is by becoming 0.5mm more than the original 2mm, helps shrinkage cavity and levels off to the self-fusing edge side end face of body, reduced shrinkage cavity simultaneously by the trend that body floats to self-fusing edge side, continues to increase to produce negative effect; 0.2 self-fusing edge that～0.5mm is wide and body interface portion be to be become by original 2.5～3.5mm, so more aggravated shrinkage cavity and leveled off to the self-fusing edge side end face of body, guaranteed that shrinkage cavity within the molten bath of electric welding, plays the shrinkage cavity anatexis; These 2 measures have guaranteed the appearance zone of shrinkage cavity in body or body and self-fusing edge junction, i.e. shrinkage cavity in the self-fusing edge side end face of distance body in the scope of this end face 1mm, fluctuating;
The weld width of electric welding must be greater than 4mm.Though only need 2mm in theory, can cause field operation can't guarantee that the welding bead center promptly is the self-fusing edge side end face of body like this, get 4mm and can give the production tolerance of producing a flat standard.
By adopting technique scheme, beneficial effect of the present invention is: though theoretically, the shrinkage cavity of self-fusing edge still is 100% existence, but variation has taken place in the distance apart from the Face frame, by having changed to about 0.5mm about original 1.5mm, greater than 4mm and when permeating fully, shrinkage cavity is melted again at weld width, scolder by self-fusing edge is filled up, and produces thereby grind the no shrinkage cavity in back; Good through popularizing effect in an all-round way.
