Research On The Productivity Improvement Process Of YN's Cylinder Head Production Line

Cylinder head is one of the key components of diesel engine,and is the carrier of engine valve distribution system and fuel system.Because the structure of cylinder head is complex,the processing surface is more,and the matching precision is high,in order to meet the strict design and use requirements,the processing technology of cylinder head is very complex.Cylinder head processing includes cutting,tube seat ring pressing,camshaft cap tightening and leak test cleaning.It involves processing center,press-fitting machine,tightening machine,cleaning machine and leak test machine.Therefore,how to improve the production process and optimize the process to improve the production and quality of cylinder head is very important in actual production.The link.Based on the actual production situation of cylinder head,this paper introduces the technological status of the existing cylinder head line,and finds out the factors restricting the output from the various processes of cylinder head and the processing technology.At the same time,the processing rhythm of each working procedure of the cylinder head production line is analyzed,and the method of improving the output of the cylinder head is obtained,mainly the auxiliary time of the equipment and the starting rate of the equipment;the holes of the cylinder head components are analyzed,and the design personnel are communicated to improve the processing characteristics of the workpiece through the design optimization;the tool structure is analyzed.Design part of compound cutting tool to satisfy the processing of cylinder head parts,reduce tool changing time,so as to improve the processing rhythm of production line;use the theory of man-hour balance and industrial engineering principle,analyze the processing content of each process,calculate the rhythm,cancel,merge,rearrange and simplify the content of some processes to make each process simplified.The processing time is approximately the same,improving the utilization ratio of time and equipment.The output of cylinder head should be increased to 8000 per month by carrying out capacity increase.The production capacity of the whole line of cylinder head cannot be changed significantly before and after the increase.The production line balance rate of each sequence of the machining center should reach more than 90%.
