床身铸 件成品检验的内容是什么:

时间:2016-2-28 12:43:59 浏览量:875

机床床身铸件生产工 序要严格按照国际标准执行,检验标准采用《中华人 民共和国机械行业标准》JB/T 7974-1999。机床床 身铸件的成品检验主要是检验机床床身铸件的平面度和外观及其规格是否可以达到使用要求;机床床 身铸件检验一般分为铸铁平板毛坯检验、机加工 检验和成品检验两次,机床床 身铸件的毛坯主要检验外观规格是否可以达到技术要求,和毛坯 有没有内部缺陷;机床床 身铸件的机械加工检验主要是检验铸铁平板有没有沙孔、气孔、裂纹、夹沙、缩松和加工误差等。

床身铸 件铸造是比较经济的毛坯成形方法,对于形 状复杂的零件更能显示出它的经济性。如汽车 发动机的缸体和缸盖,船舶螺 旋桨以及精致的艺术品等。床身铸 件的铸造是一种能够产生重要性能和优势的工艺手段,在铸件 的生产加工中能够产生具有良好产品质量和性能的铸件产品,产生重要的质量保证。床身铸 件是将金属熔炼成符合一定要求的液体并浇进铸型里,经冷却凝固、清整处 理后得到有预定形状、尺寸和 性能的铸件的工艺过程。铸造是 现代机械制造工业的基础工艺之一。

在机床 床身铸件的国家标准和企业标准及铸铁平板的使用要求中,可以根 据实际中对铸铁平板平台的需要提出技术要求。设计机 床平板的技术要求本着以最低的成本达到最好的原则。机床床 身铸件工作面的平面度是指包容平板实际工作面且距离为最小的两平行平面间的距离,其值可按对角线法、环线法 的检定结果进行"基面变换"求得。平板工 作面的平面度是衡量平板质量的主要精度指标。按平板 工作面平面度的公差允许值确定出平板准确级别,因此必 须重视平板工作面平面度的检定。铸铁平 板是用于工件检测或划线的平面基准量具,是机床、机械制造、电子生 产等行业不可缺少的基本装备,其中以 重工业使用最为普遍。由于地区差异,铸铁平 板还被叫做铸铁平台。


The production process of machine tool bed castings should be strictly carried out in accordance with international standards. The inspection standard is JB/T 7974-1999 of the Machinery Industry Standard of the People's Republic of China. The finished product inspection of machine tool bed castings is mainly to check whether the flatness and appearance of machine tool bed castings and their specifications can meet the requirements of use. The inspection of machine tool bed castings is generally divided into cast iron slab blank inspection, machine processing inspection and finished product inspection twice, and the blank of machine tool bed castings is mainly to check whether the appearance specifications are acceptable or not. To meet the technical requirements, and whether there are internal defects in the blank; Machine tool bed casting mechanical processing inspection is mainly to check whether there are sand holes, blowhole, cracks, sand, shrinkage and processing errors in cast iron plate.

Bed casting is a relatively economical method of blank forming, which can better show its economy for parts with complex shape. Such as automobile engine cylinder block and cylinder head, marine propeller and exquisite works of art. Bed casting is a kind of technological means that can produce important performance and superiority. It can produce casting products with good quality and performance in the production and processing of castings and produce important quality assurance. Bed casting is a process in which metal is melted into a liquid that meets certain requirements and poured into the casting mould. After cooling, solidification and cleaning, the casting with predetermined shape, size and performance can be obtained. Casting is one of the basic processes in modern mechanical manufacturing industry.

In the national and enterprise standards for machine tool body castings and the application requirements of cast iron plate, technical requirements for cast iron plate platform can be put forward according to the actual needs. The technical requirement of designing machine tool plate is based on the principle of achieving the best at the lowest cost. The flatness of the working face of machine tool bed castings refers to the distance between two parallel planes which contain the actual working face of flat plate and have the smallest distance. Its value can be obtained by "base plane transformation" according to the verification results of diagonal method and loop method. Flatness of flat face is the main accuracy index to measure the quality of flat plate. According to the tolerance allowable value of flatness of flat face, the accurate grade of flat face can be determined. Therefore, the flatness verification of flat face must be emphasized. Cast iron plate is a plane benchmark for workpiece detection or marking, and it is an indispensable basic equipment for machine tools, mechanical manufacturing, electronic production and other industries, among which heavy industry is the most widely used. Due to regional differences, cast iron slabs are also called cast iron platforms.
