1、.25万份精华管理资料，2万多集管理视频讲座：.；轿车冲压件外表质量奥迪特规范主题内容与适用范围：本规范规定轿车冲压件外表质量奥迪特等级的评定方法。适用于模具制造家对轿车冲压件外表质量的出厂检查及用户对模具制造厂所制造的模具进展验收和冲压件消费检验。缺陷类别和无缺陷点数2.1缺陷类别2.1.1 A类缺陷 A类缺陷是指超出规定很大偏向，是没有阅历的顾客也能发现的缺陷。该类缺陷能引起严重的功能妨碍如渗水、整车平安性等2.1.2 B类缺陷 B类缺陷普通是指有阅历的专业人员用油石磨件之前就能摸出或看出缺陷2.1.3 C类缺陷 有阅历专业人员在目视难以发现或手摸也较难确认的情况下，经过油石磨过冲压件后能

2、看到缺陷，普通都是C类缺陷2.2缺陷点数 缺陷点数是按缺陷类别和缺陷所在区域来评定的。缺陷所在区域质量要求越高，缺陷越严重，那么缺陷点数越高。详细见表1所示。缺陷类别缺陷所在区域一区二区三区A类100点B类40点30点10点C类20点10点5点2.3阐明2.3.1外覆盖件外表不允许存在A类缺陷2.3.2车身件根据其在整车中的位置，分为三个缺陷区域(一区、二区、三区祥见第5条)2.3.3A类缺陷不按区域评定缺陷点数，这个原那么适用于一切车身件3 缺陷的断定规范 各类缺陷的断定可按表2执行 缺陷规范断定 (表2) 断定规范A类缺陷B类缺陷C类缺陷凸包和坑非常明显的、未经专业训练的人一眼就能看出的大

4、皮零落等缺陷细微的资料缺陷、磨件后可见的资料缺陷毛刺装配面上的粗毛刺大于料厚的45%有危险性的粗毛刺非装配面上的粗毛刺中等或小毛刺沖孔件料厚的20-35%拉毛未经专业训练的人一眼就能看出的拉毛非一区内用肉眼可见的拉毛非一区和二区内有拉毛裂痕缩紧制件外表有裂痕，重要部位有明晰可见的缩径制件有细微不明显的缩径压痕制件外表有裂痕，重要部位有明晰可见的缩径制件有细微可见的裂痕不明显的压痕划伤未经专业训练的人一眼就能看出的划伤非一区内用肉眼可见的划伤非一区和二区内有划伤圆角圆角半径不均匀，未到达要求，明显地不明晰、不光顺圆角半径不够均匀，不够明晰圆角切点处过度不平滑，光滑标志号标志号不明晰其它能引起严重

5、功能妨碍的缺陷对运用有明显影响的缺陷对运用无明显影响的缺陷4.断定步驟及說明4.1断定步驟4.1.1 目測断定4.1.2 戴手套触摸制件外表，手感断定。4.1.3磨制件外外表后目測断定。4.1.3.1用油石(普通規格20X20X200)磨制件外外表。4.1.3.2用相應的小油石(如10X10X100)磨圓角和不易磨到的部位。4.1.3.3按制件的外表情況(如粗糙度、有無鍍鋅屬等)迭擇油石粒度，一骰迭 400至500號粒度。4.1.3.4磨件原則上應按整車的長度方向進行，特殊部位也可橫向或斜向磨件。 圖1至圖6繪出了有代表性的几種外表件的不同部位的磨件方向和运用油 石的規格，供參考。4.2.1檢

6、查制件的每一區域，已断定的缺陷要用蜡筆圈出，井標明缺陷和匡域代號如Bl(代表一區的B類缺陷其他類推)、B2、B3等。4.2.2油箱蓋口或門把手洼赴上下部外表，同類缺陷在断定吋歸為一個缺陷。4.2.3單個的凸包不分區域，歸為一介缺陷并按一區評宙。5缺陷區域 本標准按缺陷被人反响的能够程度及其對整車外觀質量的影响程度，將整車各部面划分力三個域即:一區、二區、三匡。(見圖7)5.1.1一區 能直接被人發現缺陷的整車內外外表稱為一區。該區的缺陷嚴重影响整車的外觀質量。5,1.2二區 不能直接被人發現缺陷或須稍加留意才干發現缺陷的整車內外外表稱為二區，該區的缺陷對整車外觀質量有較大影响。5.1.3三區

7、一切被其它零件覆蓋的整車內外外表，以及在車輛运用過程中很少或短時間內不易看到的整車內外外表稱為三區該區的缺陷對整車外觀質量影响較小。5.2 缺陷區域划分例如 圖7至圖15是車型的區域划分，可供評定吋參照。6外表奧迪特等級6.l 評定方法6.1.1評是制件各部的缺陷，并標出缺陷和匡域代號(填入表5)6.1.2評出各缺陷部的缺泄點數，并累加得到該制件的缺陷點數(填入表5)。6.1.3根据點缺陷點數，在奧迪特等級對照表(表4)中按制件名稱查出對應的表 面奧迪特等級分值。6.2外表奧迪特等級對照表見表4所示外表奥迪特对照表 (表4)制件称号： 车门外板等级缺陷点数等级缺陷点数等级缺陷点数5.01061
