摘 要
生產線規(guī)劃設計是工廠設計的重要環(huán)節(jié)之一,是工藝投資成敗的關鍵,更關系到企業(yè)是否可持續(xù)發(fā)展。生產線具有較大的靈活性,能適應多品種生產的需要。在產品品種規(guī)格較為復雜,零部件數目較多,每種產品產量不多,機器設備不足的企業(yè)里,采用生產線能取得良好的經濟效益。
眾所周知,一個產品的形成過程離不開以下幾大環(huán)節(jié):產品的開發(fā)、設計、產品的制造加工、產品的部件裝配及最終裝配。這些環(huán)節(jié)構成了產品的成本因素。如今的社會,已進入了計算機與信息時代,計算機及其軟件技術的廣泛應用,使產品的開發(fā)設計及產品制造加工環(huán)節(jié)的效率大大提高,而唯有裝配環(huán)節(jié)不能覆蓋(除少數裝配工序采用機器人作業(yè)外),大量的手工勞動(人員作業(yè))仍然并將繼續(xù)存在。為提高效率、降低成本,我們須為此找出有效的分析管理方法。
本文對生產線進行了設計,主要內容包括液壓缸的結構、裝配液壓缸的工藝過程、車間平面布置以及針對液壓缸導向套裝配困難進行了立式裝缸機的設計。
關鍵詞:生產線; 液壓缸; 裝配; 車間布置;
ABSTRACT
The layout design of the production line is one of the important links in factory design,the key of the processing investment success and failure,particular involving the possibility of the continuous development of the enterprise. The production line has far flexibility, can pipelining of the multi-varieties production; In the enterprise of variety specification of the products more complex, the spare part number are more many, every kind of volume of production are less, the machine equipment is insufficient, uses the production line to be able to obtain the good economic efficiency.
Below it is well known, the forming process of a product cannot exist without several big links: The product development, the design, and the product manufacture processing, the product unit assembling and finally assembles. These links constituted the product cost element. Nowadays, The society entered computer and the information time, the computer and its software technology widespread application, causes the development design of the product and the product manufacture processes of the link is efficiency greatly to enhance, but only the assembly link not to be able to cover (uses robot work besides minority assembly working procedure), the massive of manual labor (personnel work) still and will continue to exist. In order to enhance the efficiency, reduces the cost, we must discover the effective analysis management for this.
This article design product line, primary content includes the structure of cylinder assembly, technics process of assemble cylinder assembly, plane disposal of plant and for oriented sheath of cylinder assembly assemble hard design hydraulic cylinder install the cylinder machine .
Keywords:product line; hydraulic cylinder; assembly; layout;
