Bamboo baseball bat and manufacturing method there {A Bamboo Bat And Manufacturing Method Thereof}

The present invention relates to a baseball bat and a manufacturing method thereof, and more particularly, to a baseball bat manufactured using bamboo, reinforcing the disadvantages of splitting bamboo through the drying and steaming process of hollow bamboo and providing advantages such as flexibility. The present invention relates to a bamboo baseball bat and a method of manufacturing the same, which is made by cutting a baseball bat with a bamboo stick after attaching a plurality of bamboo knit pieces with adhesive to a high-pressure press using a press machine.

Baseball bats are usually made of wood, such as maple and ash trees. Such wood can be cut into solid wood and cut into baseball bat shapes in processing equipment. After the baseball bat has been shaved into shape, painting can be done to make the baseball bat easier.

Like this, general wood can make baseball bat easily by cutting wood itself, but technology is focusing on making baseball bat that does not break well and has better hitting power. In order to overcome the limitations of wood, the development of light and unbreakable baseball bats using non-ferrous materials such as aluminum has been made.

Since the batting power depends on the baseball bat, the player wants to play with a baseball bat that is a little high and fits well.

Baseball bats are the most important offensive weapon in baseball. As the pitcher says with the ball, the batter plays with bat. And, the length of the baseball bat is usually 33 ~ 35 inches (83.82cm ~ 88.9cm), the weight is not limited, but usually 880 ~ 920g is used.

In particular, according to experts, it is very important for the material of bat to use 90% of the material. Of course the bat here refers to the wooden bat. As mentioned earlier, the most common bat material used in professional baseball is ash wood. And the bat length is used according to one's physique within the reference length range.

In general, bamboo has good flexibility and elasticity, but it is also a good condition for baseball bats. However, it is a common practice that bamboo is of course unsuitable as a material for making a baseball bat because of its weakness in shock and above all hollowness.

However, the bamboo's flexibility, elasticity and rigidity make it a good condition for baseball bats to have, and this feature is hard to find in other trees.

Therefore, if you make a baseball bat using the bamboo as described above will be able to improve the skills of the players and proceed to a more exciting baseball game.

Also, from the standpoint of the bat maker, if a star-class batter writes a monumental record using his product, the bat will be lucky enough to be displayed forever with the name of the player. Therefore, the development of a good baseball bat is essential. For this purpose, the material of the baseball bat is the most important factor.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of a bamboo baseball bat according to the present invention, Figure 2 is a process diagram schematically showing a process of bamboo bamboo in the solid wood bamboo.

1 and 2, the bamboo baseball bat 10 according to the present invention is made using bamboo. Since bamboo is hollow, it is not possible to make a baseball bat (10) having a large change in diameter by cutting the solid wood (20) itself like ordinary wood.

That is, not only can not cut the handle portion of the diameter smaller than the batting portion of the baseball bat 10, but also the hollow bamboo wood 20 has a disadvantage that is too weak to impact.

Therefore, in order to make the bamboo baseball bat 10 of the present invention shown in Figure 1 by using a bamboo to prevent bending or cracking through a variety of drying process in the form of a square long plate having a predetermined width, thickness and length. Processed bamboo knitting 30 should be made. (The various drying processes will be described in more detail in the manufacturing method below.)

The bamboo knitting 30 is cut to 10 ~ 30 years old bamboo wood 20 in combination to have a thin long shape plate shape cut into a size of width 20mm, thickness 7mm, length 2m. At this time, the width and thickness can be modified as much as the size of the bamboo.

After applying a resin adhesive to a plurality of bamboo knitting wood 30 is laminated by attaching up and down and left and right to be tightly coupled to each other to have the shape of bamboo square wood (40).

The bamboo lumber 40 has a shape that can be cut in the processing equipment, such as ordinary wood, by cutting the appearance in the shape of the baseball bat (10) and finished by sanding and painting process bamboo baseball bat (10) ) Is made.

Hereinafter, a method of manufacturing a bamboo baseball bat according to the present invention will be described in detail.

Figure 3 is a flow chart showing each step of the baseball bat manufacturing method according to the invention, Figure 4 is a detailed flow chart of the bamboo wood drying step for producing a baseball bat according to the invention.

As shown in FIG. 3, the manufacturing method of the bamboo baseball bat 10 must first go through a process of logging and drying bamboo. Bamboo suitable as a material is about 10 to 30 years old and is lumbered and dried in a natural state. Then, by pruning the bamboo, the bamboo wood 20 is cut to a length of about 2m and dried in the shade and then dried again in a drying room at about 50 ° C. to dry the bamboo in the state of the wood 20. (S100)

At this time, as shown in Figure 4, the drying step (S100) of the bamboo solid wood is subjected to the following process. The felled bamboo is first made through the first drying process of drying for about 6 months in the natural state, and the weight of the bamboo is first lightened and the gin or foreign matters of the bamboo are removed and hardened to make the bamboo wood 20 suitable for use. (S102)

In addition, the bamboo wood 20, which has undergone the first drying process, is cut to a length of about 2 m by pruning, and then subjected to the second drying in a shade where rain does not fit for about three months. (S104) In addition, the second drying The third step of drying the dried bamboo solid wood (20) in a drying field of about 50 ℃ for about two months is made of hard bamboo that is hard to split with rigidity against torsion and bending. (S106)

In addition, the well-dried bamboo solid wood 20 is cut to a size of 20mm in width, 7mm in thickness, 2m in length and cut into a plate shape to be processed into a bamboo knit wood 30. And the bamboo knitting 30 is dried by stacking each bamboo knitting 30 to cross each other to prevent bending. (S110)

The bamboo knitting 30 cut in the form of a plate is laminated on the horizontally aligned frame cross-crossing each other to dry for about two months to prevent bending or cracking characteristic of the bamboo and to hold the bamboo knitting 30 horizontally Pleated horizontal grabbing. (S120)

The bamboo grabber 30, which is completely horizontally finished, is put in the steam kneader 30 in a steam steamer in order to remove wastes such as gin and foreign matters of the bamboo and steams for about 5 days. (S130) The process will reduce the weight of the bamboo and remove the waste more completely.

After the steaming step (S130) to dry the bamboo knitting 30 for about three weeks to remove the water remaining after (S140).

A resin adhesive is applied to the bamboo dried wood knit 30, and the bamboo knit wood 30 is bonded to each other to form a bamboo lumber 40. (S150) The bamboo lumber 40 thus made is a baseball bat What is necessary is just to manufacture it with diameter a little larger than the maximum thickness of (10), and it is good to laminate | stack and bond four to the left and right, and about 12 up and down.

Therefore, the size of the bamboo lumber 40 made by bonding the bamboo knit wood 30 is made of a bamboo lumber 40 having a width of about 80mm, a thickness of 84mm, and a length of about 2m. In addition, it is also preferable to cut a larger number of the bamboo lumber 40 at the same time to cut to the required size. In addition, it is preferable to laminate the joints so that the joints cross each other like building bricks.

Then, the bamboo lumber 40 bonded by the resinous adhesive is hot pressed using a press at a temperature of about 100 ° C. to produce a bamboo lumber 40 having a stronger property than the original bamboo properties. S160)

In particular, each bamboo knit 30 is not only bonded by the resin adhesive applied to each bamboo knit 30, but also can compensate for the disadvantages of the bamboo split in impact and is more tightly coupled by pressing at high temperature .

After cutting the outer diameter of the bamboo lumber 40 made in the above process to the shape of the baseball bat (10), the surface of the bamboo lumber (40) by processing the outer surface of the bamboo lumber 40 is completed by painting and finishing the bamboo baseball bat (10). (S170)

Figure 5 is a detailed flowchart of the bamboo kebab outline processing step for producing a baseball bat according to the present invention.

As shown in FIG. 5, when the external processing of the bamboo lumber 40 is arranged step by step, first, the corner portion of the bamboo lumber 40 is cut, and then the outside diameter of the bamboo lumber 40 is processed by a processing machine. 10) It should be cut in shape. (S172)

The processing machine is equipped with the bamboo lumber 40 on the axis that rotates like a lathe to process the outer diameter with a bite. Therefore, it is necessary to sharply cut the angled portion, such as the corner portion of the bamboo lumber 40 with a knife to achieve a desired outer diameter processing.

The bamboo lumber 40, cut in the shape of a baseball bat 10, is harder than ordinary wood, resulting in a more rough surface. Therefore, the bamboo batter 40, cut in the shape of the baseball bat 10, is smoothly sanded from rough sandpaper about five times in steps, thereby finishing the surface of the bamboo baseball bat 10. (S174)

The final bamboo baseball bat 10 is completed by finishing the painting of the bamboo baseball bat 10 which repeats the process of painting and drying wood paint about five times on the finished baseball bat 10.

Here, the wood paint is preferred to use a kind such as wood urethane, olive stainless steel, lacquer in order to be painted well according to the characteristics of the bamboo.

In addition, the various drying process and drying period exemplified as an embodiment in the present invention illustrates the conditions for maintaining the desired quality of the bamboo baseball bat (10) according to the present invention. Therefore, the drying process may be increased or decreased as much as possible for better quality, and there may be any increase or decrease between dryers, and such modifications do not depart from the scope of the present invention.

In addition, the size of the bamboo knitting 30 may be larger or smaller than the size exemplified in the present invention according to the size of the bamboo solid wood 20, such a change in size can be modified.

In addition, the baseball bat manufacturing method using the bamboo described in the present invention is not limited to the baseball bat (10), it is characterized in that it can be applied to products having a general bat shape, such as trim bat, cooking rod, etc. to be.

As described above, the bamboo baseball bat according to the present invention and a method for manufacturing the same are formed by cutting the bamboo into a sheet of thin and long shape to make knitting, and bonding the bamboo knitting 30 to each other by using an adhesive to form a square shape. It was then possible to provide the bamboo baseball bat 10 by cutting it into the shape of a baseball bat 10.

Providing the bamboo baseball bat (10) is to provide a baseball bat (10) that can improve the batting power of the players by complementing the disadvantages of the good strength and elasticity of the bamboo as it is well split into the impact.
