改善锻件的内部组织、提高力学性能。

时间:2023-10-18 15:50:03

锻造厂的锻件产品是通过锻造加工塑性变形的,锻造加工是利用外力使锻件原材料产生塑性变形,获得锻件所需的尺寸、形状及性能的毛坯或零件的加工方法。通过锻造加工能消除金属在冶炼过程中产生的铸态疏松等缺陷,优化微观组织结构,同时由于保存了完整的金属锻造流线,大大加强了锻件在使用中的性能。
The forging products of a forging factory are subjected to plastic deformation through forging processing. Forging processing is a processing method that uses external forces to cause plastic deformation of the raw materials of the forging, obtaining the required size, shape, and performance of the blank or part for the forging. Forging processing can eliminate defects such as casting porosity generated during the smelting process of metals, optimize the microstructure, and greatly enhance the performance of forgings in use due to the preservation of intact metal forging flow lines.
锻造是机械制造中毛坯和零件生产的主要方法之一,常分为自由锻、模锻等。锻造加工与其他加工方法相比,具有以下特点:
Forging is one of the main methods for producing blanks and parts in mechanical manufacturing, often divided into free forging, die forging, etc. Compared with other processing methods, forging processing has the following characteristics:
1、改善锻件的内部组织、提高力学性能。锻件毛坯经过锻造加工后,其组织、性能都得到改善和提高,锻造加工能消除金属铸锭内部的气孔、缩孔和树枝状晶等缺陷,并由于金属的塑性变形和再结晶,可使粗大晶粒细化,得到致密的金属组织,从而提高锻件的力学性能。在零件设计时,若正确选用零件的受力方向与纤维组织方向,可以提高锻件的抗冲击性能。
1. Improve the internal structure and mechanical properties of forgings. After forging processing, the microstructure and properties of the forging blank are improved and improved. Forging processing can eliminate defects such as pores, shrinkage cavities, and dendrites inside the metal ingot. Due to the plastic deformation and recrystallization of the metal, coarse grains can be refined to obtain a dense metallic structure, thereby improving the mechanical properties of the forging. When designing parts, selecting the correct direction of force and fiber structure can improve the impact resistance of forgings.
2、材料的利用率高。金属塑性成形主要是靠金型线  流水槽模具 景观石 检查井钢模具 保定通风管道 隔离墩模具 保定保洁公司属的形体组织相对位置重新排列,而不需要切除金属。
2. The utilization rate of materials is high. Metal plastic forming mainly relies on the rearrangement of the relative positions of the metal structure, without the need to cut off the metal.
3、较高的生产率。锻造加工一般是利用压力机和锻锤进行成形加工的。
3. High productivity. Forging processing is generally carried out using a press and a forging hammer for forming processing.
4、毛坯或锻件的精度较高。应用先进的技术和设备,可实现少切削或无切削加工。
4. The accuracy of blanks or forgings is relatively high. The application of advanced technology and equipment can achieve minimal or no cutting machining.
5、锻造所用的金属材料应具有良好的塑性,以便在外力作用下,能产生塑性变形而不破裂。常用的金属材料中,铸铁属脆性材料,塑性差,不能用于锻造。钢和非铁金属中的铜、铝及其合金等可以在冷态或热态下压力加工。
5. The metal materials used for forging should have good plasticity, so that under external forces, plastic deformation can occur without rupture. Among commonly used metal materials, cast iron is a brittle material with poor plasticity and cannot be used for forging. Copper, aluminum, and their alloys in steel and non-ferrous metals can be processed under pressure in either the cold or hot state.
6、不适合成形形状较复杂的锻件泥杆 保定古筝 塑料增韧剂 拱形护坡模具 保定空调维修  托辊生产线。锻造加工是在固态下成形的,与铸造相比,金属的流动受到限制,一般需要采取加热等工艺措施才能实现。对制造形状复杂,特别是具有复杂内腔的零件或毛坯较困难。
6. Not suitable for forming forgings with complex shapes. Forging processing is formed in a solid state, and compared to casting, the flow of metal is limited, and generally requires measures such as heating to achieve it. It is difficult to manufacture parts or blanks with complex shapes, especially those with complex internal cavities.
