Description
技术领域Technical Field
本发明涉及球拍胚体制备技术领域,具体为一种球拍胚体的加工方法。The invention relates to the technical field of racket embryo preparation, in particular to a racket embryo processing method.
背景技术Background Art
现有的球拍在使用过程中,尤其是在高强度的击打过程中,容易产生震动,这不仅影响运动员的使用体验,还可能导致运动员的手部受伤。传统的球拍通常通过在拍框内填充减震材料来减少震动,但这种方法的减震效果有限,且增加了球拍的重量,影响了运动性能。另外现有球拍在制备过程中,缺少对球拍进行自动化夹紧并将减震材料卷绕在球杆上的自动缠绕设备,制备效率低,对此我们提出了一种球拍胚体的加工方法来解决上述问题。Existing rackets are prone to vibration during use, especially during high-intensity hitting, which not only affects the athlete's experience, but may also cause hand injuries to the athlete. Traditional rackets usually reduce vibration by filling the racket frame with shock-absorbing materials, but this method has limited shock-absorbing effects and increases the weight of the racket, affecting athletic performance. In addition, during the preparation process of existing rackets, there is a lack of automatic winding equipment that automatically clamps the racket and winds the shock-absorbing material around the club, resulting in low preparation efficiency. In response to this, we propose a racket embryo processing method to solve the above problems.
发明内容Summary of the invention

有益效果Beneficial Effects
本发明提供了一种球拍胚体的加工方法。与现有技术相比具备以下有益效果:The present invention provides a method for processing a racket embryo. Compared with the prior art, the method has the following beneficial effects:
(1)、通过将塑料薄膜管替换为碳纤维环氧树脂预浸料,成功实现了球拍的轻量化与强度增强,这一工艺不仅减少了球拍的重量,还通过相同重量的碳纤维环氧树脂预浸料置换,提升了球拍的强度,显著提升了球拍的整体性能,该工艺在保持球拍轻盈的同时,也增强了其击球减震性能,实现了球拍性能的整体平衡和优化。(1) By replacing the plastic film tube with carbon fiber epoxy resin prepreg, the racket is successfully lightweight and strengthened. This process not only reduces the weight of the racket, but also improves the strength of the racket by replacing it with the same weight of carbon fiber epoxy resin prepreg, significantly improving the overall performance of the racket. While maintaining the lightness of the racket, this process also enhances its shock-absorbing performance when hitting the ball, achieving an overall balance and optimization of the racket's performance.
(2)、通过夹紧组件的设置,实现了对卷芯的适应性自动化夹紧,满足了对不同尺寸卷芯的夹紧,方便夹紧卷芯后,方便进一步的包覆操作,通过缠绕组件的设置,实现了自动化将碳纤维环氧树脂预浸料缠绕包覆在卷芯上,无需手动操作,大幅提升了缠绕包覆的效率。(2) Through the setting of the clamping component, adaptive automatic clamping of the core is achieved, which meets the clamping requirements of cores of different sizes. After the core is clamped, further wrapping operations are convenient. Through the setting of the winding component, the carbon fiber epoxy resin prepreg is automatically wrapped around the core without manual operation, which greatly improves the efficiency of winding and wrapping.
(3)、通过驱动离合机构的设置,实现了对夹紧组件与缠绕组件之间的快速联动离合,并实现了一个电机带动夹紧组件与缠绕组件工作的效果,在不需要使用夹紧组件时,能使离合块及时与齿轮三分离,进而使缠绕组件独立进行缠绕工作,两者联动性强,又能快速进行离合,方便操作,大幅提升了工作效率。(3) By setting up the driving clutch mechanism, the clamping assembly and the winding assembly can be quickly linked and engaged, and the effect of a motor driving the clamping assembly and the winding assembly to work can be achieved. When the clamping assembly is not needed, the clutch block can be separated from the third gear in time, so that the winding assembly can perform the winding work independently. The two have strong linkage and can be quickly engaged and engaged, which is convenient to operate and greatly improves work efficiency.

步骤三、停止抽真空,把塑料薄膜管固定在卷芯一端,然后一手固定圆柱型碳纤维预浸料另一手抽出卷芯并顺势抽出塑料薄膜管,即卷制成碳纤维环氧树脂预浸料管,此时抽出塑料薄膜管减轻1.5-2克重量,以相同重量置换为碳纤维环氧树脂预浸料可提高球拍强度10-15%;Step 3: Stop vacuuming, fix the plastic film tube at one end of the winding core, then fix the cylindrical carbon fiber prepreg with one hand and pull out the winding core with the other hand and pull out the plastic film tube, that is, roll it into a carbon fiber epoxy resin prepreg tube. At this time, the plastic film tube is pulled out to reduce the weight by 1.5-2 grams. Replacing it with carbon fiber epoxy resin prepreg of the same weight can increase the strength of the racket by 10-15%;
步骤四、用滚轮碾压机碾压碳纤维环氧树脂预浸料管以排出空气,碾压压力为4公斤/平方厘米,使层间贴合紧密,提高球拍强度,用碳纤维环氧树脂预浸料折叠封闭两端开口并与球拍的中杆连接,用碳纤维预浸料在连接处包裹补强,使其形呈球拍状,把制做完成的预组件拍框固定于椭圆型治具上使碳纤维平顺,避免产生褶皱影响球拍强度;Step 4: Use a roller roller to roll the carbon fiber epoxy resin prepreg tube to expel air. The rolling pressure is 4 kg/cm2 to make the layers fit tightly and improve the strength of the racket. Use the carbon fiber epoxy resin prepreg to fold and close the openings at both ends and connect them to the middle pole of the racket. Use the carbon fiber prepreg to wrap and reinforce the connection to make it look like a racket. Fix the finished pre-assembly racket frame on an elliptical fixture to make the carbon fiber smooth and avoid wrinkles that affect the strength of the racket.
步骤五、将预组件放入模具内并合模,将模具移进热压设备中,施以90-110吨/平方米压力,让模具快速受热,环氧树脂固化温度为135-140摄氏度,固化时间为30-40分钟,此间预置在碳纤维预浸料夹层的固态扩胀填充材料在模具内受热扩胀增大,固态扩胀填充材料的膨胀倍率为50-90倍,受热膨胀后能产生5-10公斤/平方厘米扩胀压力,碳纤维环氧树脂预浸料在扩胀压力和模具型腔限制作用下快速固化定型,热固化结束后将模具移进冷却机进行快速降温,冷却时间为4-5分钟,冷却至常温打开模具即制成实心球拍初坯。Step 5. Place the pre-assembly into the mold and close the mold, move the mold into the hot pressing equipment, apply a pressure of 90-110 tons/square meter, heat the mold quickly, the epoxy resin curing temperature is 135-140 degrees Celsius, and the curing time is 30-40 minutes. During this period, the solid expansion filling material pre-placed in the carbon fiber prepreg interlayer expands and increases in the mold due to heat. The expansion ratio of the solid expansion filling material is 50-90 times. After thermal expansion, it can generate 5-10 kg/square centimeter expansion pressure. The carbon fiber epoxy resin prepreg is quickly cured and shaped under the expansion pressure and the limitation of the mold cavity. After the heat curing is completed, the mold is moved into the cooling machine for rapid cooling. The cooling time is 4-5 minutes. After cooling to room temperature, the mold is opened to form a solid racket blank.
