摘要： PURPOSE:To obtain a cylindrical member with normal work length and shape size of a curl part by chucking a work having bead parts formed and detecting that the work length is in a reference size, and then performing curling work. CONSTITUTION:A cylindrical work W is clamped between split dies with annular grooves to form the bead parts. This work W is mounted on the supporting surface 24 of a supporting member 22, a pushing and detecting/measuring device 32 is moved to bring a pusher 40 into contact with one end of the work W, and the work is moved to a stopper 28. The length of the work W is measured by a measuring device 46 and when it is not within a reference side range, following processes are stopped. When the detected length is within the range, the work W while contacting the stopper 28 is clamped by a presser member 54 and the supporting member 22. Then, the recessed groove 56 of a curling roller 58 is pressed against the opening part 20 of the work W and the opening part 20 is curled gradually to obtain a specific-length cylindrical member which has the specific curl part 18 and bead parts 14 and 16.
摘要翻译：目的：通过夹紧形成有胎圈部件的工件并检测工件长度为参考尺寸，然后进行卷曲加工，获得具有正常工作长度和卷曲部分形状尺寸的圆柱形构件。构成：将圆柱形工件W夹在具有环形槽的分割模具之间以形成胎圈部件。该工件W安装在支撑构件22的支撑面24上，推动检测/测量装置32移动以使推动器40与工件W的一端接触，并且工件移动到止动件28 工件W的长度由测量装置46测量，当不在参考侧范围内时，停止后续处理。当检测到的长度在该范围内时，接触止动件28的工件W被压紧构件54和支撑构件22夹紧。然后，将卷边辊58的凹槽56压靠在开口部20上工件W和开口部20逐渐卷曲以获得具有特定卷曲部18和胎圈部14和16的特定长度的圆柱形构件。
