    • A method of assembling exhaust components comprising the steps of: (a) providing an exhaust plate or other exhaust component (12) having a first side (24), a second side (26), and an embossment (32), the embossment (32) defining an aperture (34) and a void (36) contiguous with the aperture (34); (b) providing an exhaust pipe or other mating exhaust component (14) having an end portion having a leading end, the end portion sized to be received by the void; (c) inserting the end portion of the exhaust pipe (20) into the void (36); and (d) bending a portion of the embossment (32) over the leading end of the end portion to lock the exhaust plate to the exhaust pipe. Step (d) may include flaring the embossment (32) and a leading portion of the end portion of the exhaust pipe (20). Step (d) may be performed by punching the embossment (32) to deform the embossment (32) and the leading portion of the end portion of the exhaust pipe (20).
    • 一种组装排气部件的方法,包括以下步骤:(a)提供排气板或其它排气部件(12),其具有第一侧(24),第二侧(26)和压花(32),压花 32)限定孔(34)和与孔(34)邻接的空隙(36); (b)提供具有前端的端部的排气管或其它配合排气部件(14),所述端部尺寸被所述空隙容纳; (c)将排气管(20)的端部插入空隙(36)中; 和(d)将压花部分(32)的一部分弯曲在端部的前端上,以将排气板锁定到排气管。 步骤(d)可以包括使压花(32)和排气管(20)的端部的前端部分扩张。 步骤(d)可以通过冲压压花(32)来使压花(32)和排气管(20)的端部的引导部分变形。
