在生产录音机的过程中,磁头部分的制造是比较困难和复杂的,录音机整机的质量好坏,很大程度上取决于磁头的质量,所以必须解决磁头的生产问题。磁头的质量好坏直接取决于冲制后的铁芯片质量的优劣,所以一定要解决铁芯片模具的设计和制造问题。我厂生产录音机已20多年了,但是铁芯片模具的制造至今仍未完全过关,因有不少单位和工厂来参观铁芯片模具,提出的共同问题就是怎样使铁芯片模具的制造达到符合产品图纸毛刺≤0.01mm片面平整的要求。
In the process of producing the recorder, the manufacture of the magnetic head part is more difficult and complicated. The quality of the whole recorder depends very much on the quality of the magnetic head, so the production of the magnetic head must be solved. The quality of the magnetic head depends directly on the quality of the iron core after punching, so we must solve the design and manufacture of the iron core die. Our factory has been producing tape recorders for more than 20 years, but the manufacture of iron sheet mold has not yet been completely passed. Because many units and factories have come to visit iron sheet molds, the common question raised is how to make iron sheet molds to meet the product drawings Burr ≤ 0.01mm flat surface requirements.
