The Research And Application Of The Tractor Manufacturing Ability Promotion Project

Second First Tractor Company Limited assembly plant(hereinafter referred to as the second assembly plant) is small and medium horsepower wheeled tractor assembly plant, its products include belt drive and direct drive tractors in two categories, the main models of SG series direct drive tractor has passed the E-mark certification and CE certification, the products have been exported to Britain, Spain, Serbia, Hungary, Ukraine, Brazil the United States and Africa and other countries in the world, has been accepted by foreign users, optimistic about the prospects. The maximum capacity of existing assembly lines of only 30 units / day, seriously restricting the SG Series Tractor sales increase, so the transformation of the assembly line, the increase of auxiliary equipment, improve assembly capacity and product quality issues emerged.The main research contents are as follows: through the re planning of the process layout, the transformation of assembly production line, and the addition of supporting technology and equipment and testing facilities:(1) product line transformation: the transformation of the assembly support, chain plate, suitable for chassis assembly product line, on both sides to increase light rail, to reduce labor intensity, improve the efficiency of assembly. There is a corresponding increase in equipment coating machine Taiwan, Taiwan two, two Taiwan induction heater through cleaning machine.(2) increase the shaft of tractor assembly unit of a group: add two Taiwan and non-standard press manipulator two sets. Through improving the assembly condition of the existing half shaft, the single class combination half shaft assembly is achieved without increasing or decreasing the assembly personnel. The use of special press, pressing wheel fixing screws, drive axle and the corresponding bearings, meet the production requirements at the same time, improve product quality, reduce labor intensity, improve work efficiency.(3) assembly line transformation: the transformation of the assembly support, chain plate, to achieve flexible production, taking into account the SG series(25 ~ 40 horsepower) and the assembly of product variants. The corresponding increase equipment rear wheel tightening machine two sets, two sets of electrical test instrument, sealing test desk set, the PTO test station, by adding auxiliary equipment to enhance product quality on-line detection ability, improve product quality.Through the implementation of the above projects, to achieve class production capacity of 120 units, to meet the production needs. At the same time in the case of a large number of mechanical equipment, can significantly reduce labor intensity, improve assembly quality, reduce failure rate, improve product market competitiveness.
