Abstract

A method for manufacturing the baseball bat includes such steps as coating resin on fibrous cloth, winding it around iron core, winding thermo-shrinking adhesive belt, baking at 80-160 deg.C for 1-5 hr, removing iron core, and removing adhesive belt. It has high productivity and beautiful appearance.

Description

A kind of method for producing baseball bat

Technical field:

The present invention relates to baseball pole technology field, the production method of refering in particular to a kind of baseball bar.

Background technology:

In the prior art, the baseball bar that has is to adopt timber, bamboo or aluminium material to make, and it is mainly by hand and is processed as the master, and the production time is long, the cost height, and the tissue of timber and bamboo can't be controlled, very easily fracture, and the baseball bar shock-proof effect that aluminum is done is poor.Occur to adopt glass fabric or carbon cloth etc. to make the baseball bar subsequently, it is produced and adopts oil pressure moulding process, and its technical process is: at first with glass fiber or be made into glass wool cloth; Specification according to the baseball bar is cut into baseball bar expansion plane appearance to glass wool cloth then; The glass wool cloth that cuts is pinched the pre-formed baseball bar apperance that is by hand; Put into ready-made in advance mould mechanical oil-pressure moulding then; Depanning after the oil pressure moulding; Because the thick embryo outward appearance after the depanning is bad, to carry out the hacking limit after the depanning, mend the soil processing, make its surface become smooth to destroy the burr on the thick embryo and the aperture on the thick embryo to be mended native the processing with a kind of very thick coating.The shortcoming of this process is: (1) complex process, its pre-formed operation, oil pressure molding procedure and go out in the die process production process not easy to operate.(2) thick embryo outward appearance is relatively poor, also will carry out the hacking limit after the depanning and mend the soil processing, causes complex manufacturing, cost height and production efficiency low.(3) adopt the oil pressure moulding process, need bigger mould and oil pressure former, equipment investment, mould investment height, and also power consumption is also higher in the production process.(4) its pre-formed process and oil pressure forming process are owing to complicated operation, and it is not easy to operate to go out mold process simultaneously yet, thereby causes production efficiency low.

Summary of the invention:

The objective of the invention is to overcome the defective of prior art, a kind of method for producing baseball bat is provided, this method has easy operation, production efficiency height, advantage that production cost is low.

For achieving the above object, the technical scheme of method for producing baseball bat of the present invention comprises following process:

(1) rolling glass fabric, carbon cloth, Ke Weila fiber cloth or the chemical fiber cloth that will scribble resin rolls on iron core, before this each fiber was knitted layer, and re-used glass fabric, carbon cloth, Ke Weila fiber cloth or chemical fiber cloth volume and twine in reaching outer peripheral face between each lamination;

(2) the encapsulate band twines the thermal contraction type adhesive tape in outermost fibers cloth outside;

(3) the baking iron core that will be surrounded by fiber cloth and adhesive tape is put into baking oven and is toasted, and baking temperature is 80 ℃～160 ℃, and the time is 1.0～5.0 hours, adjusts according to needed thickness;

(4) move back iron core iron core is withdrawed from, obtain thick embryo;

(5) moving back adhesive tape takes the adhesive tape of the thick embryo surface of baseball bar off.

In the said method, described iron core upper glass fiber cloth, carbon cloth, Ke Weila fiber cloth or chemical fiber cloth can be rolled up 5～30 circles, the gross thickness of glass fabric, carbon cloth, Ke Weila fiber cloth or chemical fiber cloth is 1.0～6.0mm, can determine according to the diameter of club.

The process of rolling can roll also and can roll by bushing machine by manual, promptly can move back also and can be undertaken by moving back the iron core machine by manual and move back the iron core process.

Adopt the thermal contraction type adhesive tape to wrap in glass fabric, carbon cloth, Ke Weila fiber cloth or chemical fiber cloth surface among the present invention, be subjected to thermal contraction when in baking oven, toasting, produce pressure glass fabric, carbon cloth, Ke Weila fiber cloth or chemical fiber cloth are compressed, the resin on glass fabric, carbon cloth, Ke Weila fiber cloth or the chemical fiber cloth is heated the glass fabric, carbon cloth, Ke Weila fiber cloth or the chemical fiber cloth that are rolled into multilayer is bonded as one simultaneously.

Method for producing baseball bat of the present invention is compared with traditional production method, has following advantage:

(1) the simple used glass fabric that scribbles resin, carbon cloth, Ke Weila fiber cloth or the chemical fiber cloth of technical process can obtain by directly purchasing on the market, do not need to weave cotton cloth, and thick embryo is without the hacking limit and mend soil and handle, and rolls in addition, the encapsulate band, toasts, moves back iron core and move back the adhesive tape process and all belong to fairly simple technical process.

(2) its production process of processing ease mainly constitutes by rolling, toast and move back the iron core process, compares its operation with traditional baseball bar manufacturing procedure and is more prone to, and does not need higher production skills just can finish.

(3) in low its production method of cost, by roll-forming on iron core, and use the baking oven baking molding, compare with traditional employing mould, oil pressure moulding process, only need iron core and baking oven, equipment investment and energy consumption are all lower.

(4) the production efficiency height is because technology is simple, production process is easy and simple to handle, so can enhance productivity greatly, particularly roasting procedure can toast in a baking oven simultaneously in batch, can intermittently operated can carry out the flowing water continued operation again.

(5) it is better that product appearance adopts the thick embryo outward appearance of product of this method production well, no burr, aperture, and not needing to carry out the hacking limit and mend the soil operation can direct mopping.

The specific embodiment:

Method for producing baseball bat of the present invention mainly comprises the steps:

(4) move back iron core iron core is withdrawed from, obtain thick embryo;

Below in conjunction with specific embodiment method for producing baseball bat of the present invention is described further, to help understanding content of the present invention.
