Abstract

The invention discloses a production method for a golf club head. The golf club head is provided with titanium alloy ball head parts respectively with grooves for changing of rods. The production method for the golf club head includes the steps of dividing the maximum deformation quantity of each groove into a plurality of deformation quantities while keeping each deformation quantity no more than the maximum deformation quantity of titanium alloy in the time of single forging of the titanium alloy; designing corresponding forging moulds according to the divided deformation quantities while enabling the maximum deformation quantity of a first forging mould to correspond to the deformation quantity of a first division, and enabling the maximum deformation quantity of a first mould and the deformation quantity of a second division to be the maximum deformation quantity of a second forging mould; enabling the maximum deformation quantity of the last forging mould equal to the maximum deformation quantity of the groove based on the division numbers of the maximum deformation quantity of the groove, and so forth; controlling the forging mould deformation quantity required each time within a reasonable range by means of a production method of step-by-step forging, and forging the ball club head parts with larger deformation quantity through the cumulative forging of limited groups of forging moulds.

Description

A kind of manufacture method of golf club

Technical field

The present invention relates to a kind of manufacture method of golf club, this golf club has the titanium alloy bulb loose mail being with interchangeable bar groove.

Background technology

The material of the golf club that current market is generally common has steel alloy, aluminium alloy, stainless steel, ceramic plane, titanium alloy etc., select the bulb of different materials can make play maximum function during strike, so seek the raw material of material as golf club of mechanical performance excellence, be the target of manufacturer invariably painstakingly for pursuing of the golf club of Present Global, and current material take titanium alloy as the best, it is low that its characteristic just conforms with density, intensity and the high condition of elasticity, and its intensity, mechanical performance and antioxidant anticorrosive are the most excellent.

Though currently used titanium alloy can be described as, to meet density low, the optimum feed stock of good two conditions of intensity, but because the resistance of deformation of titanium alloy is larger, if titanium bulb has more complicated appearance, especially there is comparatively large deformation amount, when making forging drop larger, traditional forging method is very difficult, therefore generally casting method is adopted, but because the mobility of titanium alloy melting liquid is not good, therefore be difficult to riddle whole mould inner wall at short notice, time one is delayed, and temperature can be made to reduce, titanium alloy melting liquid can solidify because of cooling, often when liquation flows, previous liquation first solidifies, also a kind of casting disappearance is belonged to, often excessively because of the strength of knocking golf can cause inner unbalance stress and certainly cast scarce place and burst apart in use, tool is dangerous, separately, titanium alloy melting liquid also can generate pore in the enclosure interior of golf club and water less than waiting casting scarce, and obvious person can choose when product examine, and not obvious person is then still dispatched from the factory becomes the defect that tool naked eyes cannot differentiate.And the above-mentioned reason because of titanium alloy melting liquid poor fluidity material itself can cause casting lack outside; the control of manufacturing environment is also one of key factor; and titanium alloy bulb must do hot investment casting in time manufacturing under a vacuum state; lack to protect the castings such as the unlikely generation oxidation of titanium alloy melting liquid, pore; and current titanium alloy precision casting is quite difficult owing to casting the control of environment, therefore be difficult to cast to obtain preferably finished product.Conventional titanium alloy ball head cast making method is lost wax casting, its method first makes the wax embryo (wax idiosome is long-pending can be larger because metal casting is shunk) of the same body with finished product, wrap up in one deck glue then to wax embryo, wrapped up in above wax embryo sticky for a kind of very thin sand again, after putting into the dry a period of time drying in constant temperature and humidity room, wrap up in one deck glue again, gluing wraps up in above sand to wax embryo again, and then wrap up in one deck glue, gluing wraps up in above some thicker sand to wax embryo again, so repeatedly several times after just define the shell mould that a wax indusium sand encased, dissolve the wax embryo removing the inside at this moment to the heating of shell mould and just define real shell mould, then centrifugal force is utilized to be poured into inside shell mould under vacuum conditions the titanium alloy having melted molten, after cooling, pound shell mould, just obtain titanium alloy blank.The method cycle of this lost-wax casting is longer, and the difficulty of at high temperature carrying out vacuum centrifugal casting is also very large.

Summary of the invention

The present invention is directed to the difficulty that titanium alloy bulb classical production process exists, a kind of new titanium alloy bulb manufacture method is provided.This manufacture method can realize the titanium alloy bulb loose mail of the interchangeable bar groove of forging band.

For achieving the above object, the technical solution used in the present invention is as follows: a kind of manufacture method of golf club, this bulb has the titanium alloy bulb loose mail being with interchangeable bar groove, first, the largest deformation amount of described groove is divided into some parts, and wherein every a deformation quantity is all no more than largest deformation amount when titanium alloy single forges; Design corresponding forge die according to split deformation quantity, wherein, the largest deformation amount of the first forge die corresponds to the deformation quantity of the first segmentation, and the largest deformation amount that the largest deformation amount of the second forge die is the first mould adds the deformation quantity of the second segmentation; According to the largest deformation amount segmentation number of described groove, the rest may be inferred, until the largest deformation amount of last forge die equals the largest deformation amount of described groove; Secondly, successively titanium alloy blank is forged into the titanium alloy bulb loose mail being with interchangeable bar groove by forge die; Finally, be connected other bulb loose mail, and carry out soldering.

Described forge die adopts forging machine to provide pressure, constant pressure during forging and stamping, and temperature range is 650 ° ~ 950 °.

Beneficial effect of the present invention is: the mode of production adopting substep forging and stamping, the deformation quantity of each for forge die required forging and stamping can be controlled in the reasonable scope, forge and press out by the accumulation forging and stamping of limited group of forge die the bulb loose mail had compared with large deformation amount, solve traditional forging method and cannot produce the problem with larger forging drop product.This Forging Technology is compared conventional casting techniques and is very simplified, and highly shortened the production cycle, reduces production cost, and the titanium alloy bulb of forging, its mechanical performance is comparatively cast and will be got well.
