The invention discloses an end cover for a grounding device of a rail train and a preparation method thereof. The end cover is made of an SMC composite material. The specific preparation method comprises the steps that S1, the SMC composite material is machined through a numerical control machine tool, manual polishing machining is assisted, an end cover finished product made of the SMC composite material is obtained, and the weight of the end cover finished product is weighed; S2, a corresponding mold is designed and manufactured according to the end cover finished product; S3, the mold is placed in a mold temperature controller, the mold is heated, and the temperature of the mold is kept within the temperature range of 150 DEG C +/-10 DEG C; S4, an SMC composite material with the weight 1.2-1.5 times that of the finished end cover is weighed and added into the mold, pressure is applied for pressing, and the pressure is kept for 20-35 min; and S5, the formed end cover product is taken down from the mold, and the end cover is obtained. The prepared end cover is long in service life, excellent in aging resistance and corrosion resistance, stable in size, excellent in mechanical performance, capable of being industrially produced in batches, stable in production quality and relatively simple in process.

    本发明公开了一种用于轨道列车接地装置的端盖及其制备方法,所述端盖的材质为SMC复合材料。具体制备方法为,S1:通过数控机床对SMC复合材料进行加工,并辅以手动打磨加工,获得由SMC复合材料构成的端盖成品,称取该端盖成品的重量;S2:根据端盖成品设计并制造相应模具;S3:将模具安置在模温机中,对模具进行加热,使模具温度保持在150℃±10℃的温度范围;S4:称取端盖成品1.2~1.5倍重量的SMC复合材料,将其加入模具中,施加压力进行压制,保压20~35min;S5:从模具中取下成型的端盖产品,即得。本发明制备的端盖使用寿命长,抗老化、耐腐蚀性能优异,且尺寸稳定,机械性能优越,且能够批量化工业生产,生产质量稳定,且工艺相对简单。
