如何检验锻件加工的质量?

返回列表来源:济南泉西重型锻造机械有限公司 网址:www.qxzxdz.com发布日期 2017-07-03 浏览:

  锻件加工缺点的存在,有的会影响后续工序处置质量或加工质量,有的则严重影响锻件的性能及运用,乃至地下降所制成品件的运用寿命,危及安全。

  There are some disadvantages of the forging processing, will affect the subsequent disposal of quality or processing quality, some serious influence on the performance and application of forgings, and greatly reduced the service life of the parts manufactured goods, endanger the safety of.

  济南锻造锻件质量的查验包括外观质量及内部质量的查验。外观质量查验主要指锻件的几许尺度、形状、外表状况等项目的查验;内部质量的查验则主要是指锻件化学成分、微观安排、显微安排及力学性能等各项目的查验。锻件的外观质量查验也即是查看锻件的形状、几许尺度是不是符合图样的规则,锻件的外表是不是有缺点,是什么性质的缺点,它们的形状特征是什么。外表状态的查验内容通常是查看锻件外表是不是有外表裂纹、折叠、折皱、压坑、桔皮、起泡、斑疤、腐蚀坑、碰伤、外来物、未充溢、凹坑、缺肉、划痕等缺点。

  Quality inspection of forging and forging parts in Ji'nan includes inspection of appearance quality and internal quality. Appearance quality inspection inspection mainly refers to forging many scale, shape and appearance of the project; internal quality inspection is mainly refers to the inspection items of chemical composition, micro forging arrangement, and mechanical properties of the microscopic arrangement. The appearance quality of forging inspection is forging shape, many see the scale is not conform to the pattern rules, the appearance is not forging flaws, what is the nature of the shortcomings, what is their shape features. The appearance of the state inspection content is usually view the appearance is not the appearance of forging defects of crack, fold, crease, indentation, orange peel, foaming, scar, corrosion pits, scratches, foreign, not full, lack of meat, pits, scratches etc..

  而内部质量的查验即是查看锻件自身的内涵质量,是外观质量查看无法发现的质量状况,它既包括查看锻件的内部缺点,也包括查看锻件的力学性能,而对重要件、要害件或大型锻件还应进行化学成分剖析。力学性能和工艺性能的查验则是对已通过规则的终究热处置的锻件和试片加工成规则试样后使用拉力实验机、冲击实验机、耐久实验机、疲劳实验机、硬度计等仪器来进行力学性能及工艺性能数值的测定。

  The inspection and internal quality is the connotation of quality check forging the appearance quality view quality cannot be found, the internal disadvantages including view of forgings, the mechanical properties including the view of forgings, and the important parts, key parts or large forgings should also carry on chemical composition analysis. Check the mechanical properties and process performance is to eventually heat treatment has passed the test rules of forging and tensile testing machine, impact testing machine, using the durability testing machine, fatigue testing machine, hardness gauge processed samples were measured after instruments such as performance and mechanical properties of the value of technology.

  化学成分的测验通常是选用化学剖析法或光谱剖析法对锻件的成分进行剖析测验,断口实验法用以查看结构钢、不锈钢(奥氏体型在外)的白点、层状、内裂等缺点、查看弹簧钢锻件的石墨碳及上述各钢种的过热、过烧等,关于铝、镁、铜等合金用来查看其晶粒是不是细致均匀,是不是有氧化膜、氧化物搀杂等缺点。

  The chemical composition of the test is usually selected chemical analysis or spectral analysis method of component analysis on the forging test, structural steel, stainless steel with a view to fracture experiment (austenitic in white), layered, inner crack defects, check spring steel forgings and the graphite carbon steel overheating, burn, on aluminum, magnesium and copper alloy used to view the grain is not uniform, is not a film, mixed oxide etc..

  低倍腐蚀法用以查看结构钢、不锈钢、高温合金、铝及铝合金、镁及镁合金、铜合金、钛合金等资料锻件的裂纹、折叠、缩孔、气孔偏析、白点、疏松、非金属搀杂、偏析集聚、流线的散布方式、晶粒大小及散布等。浸透查验法除能查看磁性资料锻件外,还能查看非铁磁性资料锻件的外表缺点,如裂 纹、疏松、折叠等,通常只用于查看非铁磁性资料锻件的外表缺点,不能发现隐在外表以下的缺点。

  Low times corrosion method for checking structural steel, stainless steel, high temperature alloy, aluminum and Aluminum Alloy, magnesium and magnesium alloy, copper alloy and titanium alloy materials such as forging crack, folding, shrinkage, porosity, porosity, segregation, white nonmetal doping, segregation of agglomeration, streamline distribution, grain size and distribution etc.. The inspection method can check the saturated magnetic material forging, but also to see the appearance defects of non ferromagnetic materials forgings, such as cracks, loose, folding, usually only for appearance defects of non ferromagnetic material view of forgings, can be found hidden in the appearance of the following shortcomings.
