高铁遮板模具成型技术，指的是将钢板经过裁剪、折弯、焊接、打磨等工序的成型技
术，它的优势很明显，成本低、效率高、节能环保等，以确保良好的使用效果，在遮
板成型时具有良好的成型效果，能够达到所需精度，不需成型后再加工，并且高铁遮
板模具使用寿命长。
高铁遮板模具由于线切割加工一般都选用晶体管高频脉冲电源，用单脉冲能量小、脉
宽窄、频率高的电参数进行正极性加工。要求获得较好的表面粗糙度值时，所选的电
规准要小;若要求获得较高的切割速度脉冲参数要选大一些，但加工电流的增大受到
电极丝截面积的限制。过大的电流将引起断丝。
High speed rail shutter mold forming technology refers to the forming
technology of cutting, bending, welding, grinding and other processes of
steel plate. It has obvious advantages, low cost, high efficiency, energy
conservation and environmental protection, so as to ensure good use
effect. It has good forming effect during shutter forming, can achieve the
required accuracy, and does not need to be processed after forming, And
the service life of high-speed rail shutter die is long.
Due to wire
cutting, the high-speed rail shutter mold generally adopts transistor
high-frequency pulse power supply, and uses electrical parameters with
small single pulse energy, narrow pulse width and high frequency for
positive machining. When it is required to obtain a better surface
roughness value, the selected electrical gauge shall be small; If higher
cutting speed is required, the pulse parameters should be larger, but the
increase of machining current is limited by the cross-sectional area of
electrode wire. Excessive current will cause wire breakage.
