摘要
随着汽车行业的发展,板簧总成生产厂对热轧弹簧扁钢产品尺寸公差精度要求越来越高。热轧弹簧扁钢产品规格覆盖范围广,热轧时活套较难投入使用,这大大制约了成品尺寸公差精度的提高。从厚度和宽度两方面影响因素阐述了热轧弹簧扁钢的尺寸公差控制,解决了热轧弹簧扁铜成品控制尺寸公差的生产问题,提高了成品尺寸公差精度。
With the development of automobile industry, the requirements of the leaf spring assembly production factory on dimensional tolerance precision of hot rolled spring flat steel products are becoming increasingly higher. For hot rolled spring flat steel product specifications covering a wide range, hot rolling loop are difficult to be put into use, which greatly restricts the improvement of the finished product size tolerance accuracy. The paper discusses on the dimensional tolerance control problems of hot rolled spring flat steel products from two aspects of the thickness and width, solves the production problems of control dimensional tolerances, and improves the product dimensional accuracy.
