我厂生产的KSGB315/6矿用移动变电站用主变压器,其侧壁的大型波纹板是采用4mm厚A3钢板弯制而成(见图1)。以前,国内曾设计制造了等节距递进成形模,但产品质量达不到要求,一次成形后还须退火,再进行第二次,第三次成形,最后整形拼装才能制成一块波纹板,但还达不到产品零件尺寸要求。去年,我们重新设计制造了波纹板成形模,产品零件一次成形,且达到技术要求。成形模具装置等节距波纹板成形装置由成形模和导向定位装置两部分组成(见图2)。其中模具部分由上模嵌板1、
The main transformer of KSGB315 / 6 mine mobile substation manufactured by our factory is made of curved steel plate with 4mm thick A3 steel plate (see Fig. 1). Previously, the domestic design and manufacture of such a progressive pitch forming die, but the product quality can not meet the requirements, a forming must be annealed, and then the second, the third forming, the final shaping assembly can be made of a corrugated board , But also less than the size of product parts requirements. Last year, we redesigned and manufactured the corrugated board forming mold. The product parts were once formed and met the technical requirements. Pitch forming device such as corrugated plate forming device by the forming mold and the orientation of two parts (see Figure 2). Which mold part by the mold plate 1,
