Analysis And Research On The Operation System Of Bulldozer Assembly Line

Chinese construction machinery industry has been a considerable scale, and accumulated a lot of skills and experience after decades of effort. With the formation of the world economy, due to China’s potentially huge market and abundant labor resources, numerous foreign technology, capital and goods have gotten into China, Chinese construction machinery enterprises are facing an unprecedented situation of intense competition at home and abroad.At present, most of our manufacturing exist universally high costs and serious waste, inefficient situation, uses the techniques and methods of industrial engineering to unearth the potential, take the connotation of development is the only way out of the predicament of enterprises. The bottlenecks in production operations analysis and the improvement of balance of manufacturability is a very important job that involves raising and lowering the production cost of production efficiency.This article select this article Shantui bulldozer assembly line as the research object, set up the advance group of the lean production operations analysis techniques, adopt the analysis of line process to develop a detailed implementation plan for the layout of the assembly line for process improvement, production line balance produce standardized guidance documents on digital equipment were set-design, build standardized production operations, and ultimately enhance the productivity of the assembly line. The main study includes two aspects:(1) For the study bulldozer chain plate assembly line, mainly based on the overalllayout and production logistics flow and distribution park bulldozers carried designed annual capacity of one million units bulldozer assembly process solutions, through analysis of product structure and bulldozers assembly sequence, the entire factory assembly line, the Department of assembly line, and logistics were the order of the layout; by hoisting equipment and transport equipment combine to drag the body is the assembly line conveyor, and finally to the assembly efficiency is maximized. In order to make the concept of flexible assembly line body design, the length of the assembly line station has adjustable, so that different types of specifications can bulldozers on-line assembly.Bulldozer is the national infrastructure used earthmoving machinery, its high operating efficiency, greater energy, volume and tonnage is also large, high prices, the market demand is not high, has maintained a relatively low level. Domestic producers bulldozer basic capacity to match market demand.In recent years, the magnitude of the domestic tractor exports rising by leaps and bounds and the domestic market demand, the domestic market in 2007, there have been in short supply. Hill pushed as domestic production, sales bulldozer’s leading enterprises, more than 65% share of the domestic market, exports accounted for about 80% of the bulldozer products.2009 Hill pushed for the expansion of production capacity to move to a new facility for the production, assembly using the latest technology, the new chain adds style sheet assembly line and ancillary facilities and equipment, bulldozers assembly capacity reached six thousand units, but the rapid increase in demand in 2010. Thus, in 2010 the company’s technology department million units of production capacity process design, the ability to expand the bulldozer assembly offline; bulldozer production combined existing park layout and logistics flow situation, after a month’s time to design an annual output of ten thousand bulldozer Technology Plan, and in accordance with the successful implementation of technology programs million units assembly process transformation of production, so that bulldozers production dramatically, significantly improve assembly efficiency, and ultimately meet the bulldozer market demand.(2) For the study of the analysis of bulldozer assembly line production operations research is in the case of put into personnel, equipment, materials and other production factors conduct bulldozer assembly to improve production time per unit volume bulldozer assembly offline station, and each station production job analysis and job order combing operation has been to reduce the tact, improve production efficiency purposes, ultimately reflected in lower manufacturing cost. In order to make the company’s bulldozers get a price advantage, and stand out in the competitive market, we must reduce production costs. Bulldozers assembled at the production site to reduce tact, improve labor efficiency; production operations analysis aims:To compare the previous period’s actual production efficiency analysis and evaluation of the current production efficiency, to acquire all the bottleneck process impact on productivity, thus improvement activities.
