Description
Technical field
The present invention relates to golf clubs, and in particular to a kind of manufacturing method of easy weld counterweight block.
Background technique
Totally 18 hole in golf sports throws match play into fewer number that swings and then wins, wherein each hole then corresponds to different fields
Then there is varying environment obstacle in ground, each place, as shown in Figure 1, from service area to greens on the way Equestrian-Jumping have sand pit, pond,
Lake, the woods and rough, when strike, must hit in two times and control ball in short grass section, and hypertelorism is possible to fall sand
Hole, distance, which deviates, to be possible to fall into art forest zone, lake and sand pit, must be controlled striking distance when into greens, is not strayed into rough.
To be tested in response to varying environment, golf club often totally 14, wherein including rod (Wood) 3~5, iron (Iron) 7~8
Branch, pitching wedge head (PW) 1~2, sand wedge (SW) 1, push rod (putter) 1, are broadly divided into: club wooden head, iron club,
Push rod, three classes.
Golf club head can be divided into three categories:
1. club wooden head: also known as kick off rod (Driver) and Fairway Woods (Fairway), and rod of kicking off is as its name suggests
The first ball kicked off requires distance with direction the most, and the fault of the first ball will affect ball match progress, need to beat directly, is quasi-, is remote
Rate is hit with lower mistake, therefore bulb development trend direction is enlarged, reduction material density increase bulb sweet spot area, and titanium
Tone sense is good when the mechanical property of alloy possesses higher specific strength, corrosion stability and strike, for common bulb material.Common material
Material has titanium alloy, stainless steel and composite material.The made club wooden head of composite material is with new material, new construction, new design cooperation
It most preferably beats sense, best tone sense, best accuracy out and creates optimal counterbalancing effect.
2. iron club: iron club hits purpose, and distance and direction are earnestly hoped in control mainly after kicking off, and stablizes and promotes fruit
Ridge, to direction with apart from error more require, material based on stainless steel, have expand hitting area reduce lose hit rate and reduce
The designer trends of hitting distance error, with the product development of new construction and composite material and tool shock attenuation result.
3. push rod: when push rod is used in into greens, ball is accurately driven into hole, direction and the distance of ball must be can control,
Still none standard in moulding, when how the design of functionally attention center of gravity maintains ball head of pushing rod and the cooperation of middle tube rod, the scope of attack
It will not rotate.To maintain the position of center of gravity and keep the uniformity of bulb, have in processing towards directly processing bulb using CNC, but
On conventionally manufactured based on hot investment casting, on material, stainless steel is still mainstream.
Club wooden head and iron head have been formed " trend for being not required to basket purchase " at present, thus the following titanium alloy club wooden head with it is compound
The sale ratio of the club wooden head of material will have trend higher and higher.The designs trend of bulb, mainly with reduce lose hit rate,
Based on increasing that strike is handling and being accustomed to customized corresponding different hitter's stature bulbs and different strikes.
For the design for adding clump weight on bulb, make bulb low center of gravity, to reach stable hitting property and preferably
Hitting point position, and increase twisting inertia, improve hitting distance, and the position of centre of gravity of adjustable hitter's height and habit.

Type, therefore the titanium alloy of high specific strength becomes one of rod Materials mainstream of kicking off, the Materials of iron club are more more
Sample, for the against corrosion and intensity for seeking bulb, iron club is mostly stainless steel using material.The structure composition of golf club is largely divided into
Bulb bottom, hitting area and neck, wherein neck is the tie point for connecting club, and the torsion generated when hitting in strike holds
It easily reverses, in order to increase the smooth and good hitting point of strike, the adjustment of center of gravity is even more important, lower center of gravity and suitable
When counterweight and position be adjustment hit important key.
The position of center of gravity will will affect flight path, direction and the distance of ball in the strike of golf, by taking iron club as an example,
The design maximum differential point of hollow back formula and knife spine formula in, density design direction on the contrary, difference is very big in exterior design, hollow back
Though formula design can effectively reduce and lose rate of hitting and but improve the range error after batting, the design of knife spine formula mainly contracts bulb volume
It is small, it can effectively improve the flying distance error after batting to change its batter's box but.Golf club head as shown in Figure 2 and Figure 3 is not
With angle striking distance difference.
To make bulb low center of gravity and freely adjusting center of gravity, the cooperation of clump weight design mainly has following three:
1. screw lockable clump weight
Lockable clump weight mainly cooperates principle to be that golf club head bottom cover has the solid lock screw hole of fixation, screw solid lock
There are two types of modes for formula clump weight, first is that another kind is that screw itself has both counterweight with screw by clump weight solid lock in bulb bottom cover
With the function of solid lock.Such clump weight mainly has both solid lock and advantage easy to loading and unloading.
2. embedded clump weight
Embedded clump weight mainly cooperates principle and lockable, and some are difference, embedded the same embedding with what is fixed in bottom cover
Based on entering slot, fasten clump weight using clump weight external form and dimensional tolerance, such clump weight cooperation, possess quick despatch it
Advantage.
3. welded type clump weight
The main counterweight in a conventional manner of welded type clump weight, with welding manner by fixed weight block welding in bulb bottom,
The case where forming different club difference counterweights, but welded type clump weight is if the material for selecting to have larger difference with bulb
Will cause welding surface and bulb body has the defect of color difference, if selection will limit clump weight with material similar in bulb again
Density adjustment, this contradiction greatly limit effective application of welded type clump weight.
