Dongfeng Commercial Vehicle Powertrain 4H/X7 mixed-flow assembly line officially put into production

According to the new plant expansion plan for the powertrain, the Dongfeng 4H engine assembly line was moved from the old factory to the new factory on June 25th. With the joint efforts of the Dongfeng Commercial Vehicle Engine Plant and the special equipment manufacturing plant, it took only 2 months. Time, completed the relocation, installation and commissioning of more than 40 sets of (4) sets of 4H and X7 mixed-flow assembly lines. After two weeks of small-scale trial production, the new assembly plant of the powertrain 4H/X7 was officially put into production on September 11th.

In the powertrain 4H/X7 mixed-flow assembly plant, the reporter saw a busy and bright factory building where two production lines were lined up in parallel. More than 30 workers were busy and busy, assembling, assembling, and testing. Process. According to Wang Rongchang, head of the powertrain workshop, in the early stage of the construction of the line, the factory actively carried out ILU skills training to improve the staff's ability to handle abnormal operations, as well as the proficiency and accuracy of high-production operation equipment inspections, so that the new line 4H engine With a daily production capacity of 60 units, the number of personnel is reduced by 20 people. The compact layout of the new line and proper job programming have resulted in a substantial increase in labor fullness and a 30% increase in personnel efficiency.

The engine factory took 4H relocation as an opportunity to fully promote technological transformation. The 4H/X7 mixed-flow assembly line self-manufactured parts and semi-assembly logistics methods on and off the line changed from forklifts to self-suspended chains, avoiding collisions and scratches caused by forklift trucks. Reduced appearance defects. At the same time, the technical team introduced new error prevention techniques, such as the error prevention of electric wrenches, so that the operator will be automatically released after the torque and the number of bolts are all qualified; the misdiagnosis of differential parts guarantees both 4H and X7 When the engine is mixed, there are misplaced parts. The change in logistics methods, the use of a number of error-prevention technologies, and on-site safety improvements have further improved the quality assurance capabilities and safety assurance capabilities of the new line.

According to Sheng Qiguang, head of the powertrain workshop, the 4H/X7 mixed-flow assembly line has already achieved a 30,000-ton capacity for the Dongfeng 4H engine, and the X7 engine's 30,000-capacity capacity is expected to be formed after the X7 engine is put into operation in October. It will then realize the mixed flow of the 4H engine and the X7 engine. produce.
