纸梗火柴机上的眼板是用8毫来树脂层压布板加工的,上面有2950个ф1.5小孔,这些小孔组成的行列间距都有公差要求,过去加工是在带孔的模扳上靠手工一个一个地打洋冲眼,定小孔的位置。结果打出的洋冲眼很多歪斜和遗漏,工效低,质量不易保证。为此,我厂设计加工了一副压模板(附图),在平压机上一次就把工件上所有的洋冲眼冲出。工效和质量大大提高。这块压模板是用30毫米厚的钢板经调质处理后,磨平上下两面,
Paper stems on the matchstick eye board is 8 millimeters of resin laminated cloth processing, above the 2950 ф1.5 holes, these holes are composed of the ranks of pitch tolerance requirements in the past processing is in the mold with holes Pull one by one by hand to hit the ocean red eye, the location of small holes. The result is a lot of skewed and missed shots, ergonomics, quality is not easy to guarantee. To this end, I plant a mold design and processing template (with photos), the last time in the flat-bed press on the workpiece all the red out of the hole. Ergonomics and quality greatly improved. This piece of the template is 30 mm thick steel quenched and tempered, polished up and down both sides,
