Design and Application of Chamfering Machine of JCOE Pipe Production Line

Described in the article are the three arrangement types of the chamfering machine currently used by domestic JCOE pipe production lines，and advantages and disadvantages of each type.Focused on is the first arrangement type of the machine which involves that chamfering of both ends of one pipe are being conducted simultaneously and separately by the two headstocks as moving long the same axis，and that the pipe is charged and discharged by the transfer car.And also elaborated are details of the design characteristics of the main aspects of the chamfering machine arranged as above mentioned，including the drive system，the automatic control and the safetyinterlinking protection mechanism，etc.The production efficiency of the machine is mentioned，too.The actual operation result demonstrates that the chamfering machine is in possession of such advantages as scientific and reasonable arrangement，proper structure， precise control， high accuracy and high production efficiency， being capable of meeting the production requirements.
