非金屬非標準件
標準零部件是指結構、尺寸、畫(huà)法、標記等各個(gè)方面已經(jīng)完全標準化,并由專(zhuān)業(yè)廠(chǎng)生產(chǎn)的常用的零(部)件,如螺紋件、鍵、銷(xiāo)、滾動(dòng)軸承等等。 廣義包括標準化的緊固件、連結件、傳動(dòng)件、密封件、液壓元件、氣動(dòng)元件、軸承、彈簧等機械零件。 狹義僅包括標準化緊固件。 國內俗稱(chēng)的標準件是標準緊固件的簡(jiǎn)稱(chēng),是狹義概念,但不能排除廣義概念的存在,。 此外還有行業(yè)標準件,如汽車(chē)標準件、模具標準件等,也屬于廣義標準件
Standard spare parts refer to zero parts, such as threaded parts, keys, pins, rolling bearings, which have been completely standardized in structure, size, drawing, marking and other aspects and are produced by professional factories. Generally speaking, it includes standardized fasteners, connectors, transmission parts, seals, hydraulic components, pneumatic components, bearings, springs and other mechanical parts. In a narrow sense, only standardized fasteners are included. The standard parts commonly known in China are abbreviated as standard fasteners, which are narrow concepts, but the existence of broad concepts can not be excluded. In addition, there are also industry standard parts, such as automobile standard parts, die standard parts, etc., also belong to the generalized standard parts.
非標準件主要是國家沒(méi)有定出嚴格的標準規格,沒(méi)有相關(guān)的參數規定之外,由企業(yè)自由控制的其他配件。非標準件有很多品種,目前沒(méi)有很規范的分類(lèi)。大致分類(lèi)如下:
The non-standard parts are mainly other parts which are controlled freely by the enterprise besides the strict standard specifications and relevant parameters stipulated by the state. There are many kinds of non-standard parts, and there is no very standard classification at present. The general classification is as follows:
金屬非標準件:
Metal non-standard parts:
由客戶(hù)提供圖紙,廠(chǎng)家根據圖紙利用設備制作出相應的產(chǎn)品,通常是模具居多,公差要求,光潔度都是客戶(hù)規定的,沒(méi)有一定的范式。產(chǎn)品從鑄造到精加工完全需要相應的質(zhì)量控制,工序復雜且可變性大,一般成本高于標準件。
Customers provide drawings, manufacturers use equipment to produce corresponding products according to drawings, usually molds, tolerance requirements, smoothness are prescribed by customers, there is no certain paradigm. From casting to finishing, products need corresponding quality control. The process is complex and changeable, and the general cost is higher than standard parts.
非金屬非標準件:
Non-metallic non-standard parts:
是一些非金屬材料的加工。諸如塑料,木材,石材等,近年來(lái),注塑行業(yè),塑料模具的發(fā)展日益精進(jìn),曲面設計,編程數控的引用,使得非標加工的成本和公差等級都有了很大的提升。
It is the processing of some non-metallic materials. For example, plastics, wood, stone and so on. In recent years, the development of plastic injection industry and plastic mould has been increasingly advanced. The introduction of surface design and NC programming has greatly improved the cost and tolerance level of non-standard processing.
