模乐虎手机版的技术要素
乐虎手机版的技术要求,包括手机版粗糙度和手机版缺陷量两个方面。
The technical requirements of the surface of the forgings include two aspects of the surface roughness and the amount of the surface defects.
1、手机版粗糙度
1, surface roughness
锻压过程中,由于表层金属被氧化、外来物嵌入、金属流动不均匀、官网手机版不平、银后的辅助工序不当等多种因素的影响,都会使乐虎手机版呈现峰谷相间和凹凸不平的微观几何特征,这种特征一般用粗糙度来表示。
The forging process, because the metal surface affected by auxiliary processes, oxidation, foreign object embedding, uneven metal flow and die surface uneven, silver after improper factors, micro www.gangmoju.com.cn www.gaibanmoju.org.cn www.hupomojuu.cn www.hupomoju.org.cn www.ludenggan.net.cn www.feijiudianlan.cngeometric features will peak and valley and the uneven surface so that the characteristics of the forging, generally used to represent roughness.
乐虎的手机版粗糙度待征与机械加工手机版相比,有如下特点:
The surface roughness of the forgings is compared to the machined surface, which has the following characteristics:
(1)不均匀性大,同一乐虎的不同部位,同批次的不同乐虎都会有较大的差异。
(1) there is a big difference between the different parts of the same forgings and the different forgings of the same batch.
(2)由于乐虎手机版是金属受压充填型槽的结果,不像机械加工用挤切方法.剥离金属,因此手机版的凹凸过渡较为平缓,而且峰尖和谷底多为钝角。
(2) the forging surface is metal compression filling groove machining results, unlike with dissectible. Peel metal, so the surface transition surface is relatively smooth, and the peak and valley is the obtuse angle.
(3)由于乐虎手机版缺陷较多,微观的凹凸不平,凹部多为点状孔穴形态,往往与宏观手机版的凹坑相混淆。
(3) due to the large forging surface defects, micro uneven, concave to point hole shape, often with macroscopic surface pits confused.
乐虎的手机版粗糙度,目前尚无正式标准。一般情况下,对加工手机版与正常的非加工手机版均不规定手机版粗糙度,但精乐虎的手机版一般均应规定。
There is no formal standard for the surface roughness of the forgings. Generally, the surface roughness is not specified on the surface of the machined surface and the normal non machined surface, but the surface of the fine forgings should be specified.
2、手机版缺陷
2, surface defect
乐虎手机版缺陷有裂纹、折叠、折皱、压坑、碰伤、针孔等。其中一部分是由于游戏温度过高或受到腐蚀,使材质受到损伤而在乐虎手机版上呈现某些异常待征(如过烧裂纹、针孔等),或是由于操作原因、乐虎设计不当而造成的缺陷(或金属流线不顺),一般都不可能依靠矫正处理的办法予以挽救,因此这些缺陷称为不允许缺陷。而另一些因机械原因造成的缺陷(如碰伤、压坑、应力裂纹),只要排除掉或是能确认对零件不产生影响,则这些缺陷是允许的。排除缺陷时打磨的凹坑,其宽深比b/h应有限制:对钢、铝乐虎,b/h应不小于5;而对钛合金、高温合金乐虎,则b/h应不小于8。
The surface defects of the forgings include cracks, folds, creases, pits, bruises, pinholes and so on. One part is due to the heating temperature is too high or corroded, the material damage and in forging presents on the surface of some abnormal characteristics (such as burning crack, pinhole etc.), or due to operational reasons, forging defects caused by improper design (or not, usually metal streamline) are impossible to rely on the correct treatment the way to be saved, so called defects do not allow these defects. Other defects caused by mechanical reasons, such as bumps, craters, stress cracks, are excluded if they are excluded or confirm that they do not affect the parts. When the defect is removed, the width and depth of the grinding pits should be limited compared to that of b/h. For steel and aluminum forgings, the b/h should be no less than 5, while for titanium alloys and Superalloy Forgings, the b/h should be no less than 8.
