Abstract:
The aim of this paper is to review the state-of-the-art SFPs and their applications, and to provide a guide for researchers and engineers working in this field. Various SFPs are classified according to the combination ways of stamping and forging operations.The process principle of each combination is reviewed, with its applications discussed. The state-of-the-art of SFPs suggests that future work in this field should focus on the development of high-strength die materials, better lubrication control methods, forming machines with intelligent control capacity and special functions, and some new SFPs for high strength or ultra-high strength materials.

综述:板材零件冲锻成形研究进展

王新云,金俊松,邓磊

创新点说明:

1) 按照工艺组合方式,将板冲锻成形分为复合成形方法与板锻成形方法两大类,并将每大类进行细分;

2)基于对板冲锻工艺的发展现状综述,指出高强度模具材料、新型的润滑技术、功能更丰富的智能冲锻设备以及适用于高强钢板冲锻方法是板冲锻工艺未来的发展方向。

研究目的:

通过对冲锻工艺进行分类归纳和总结,为从事该领域的研究人员、工程师提供应用参考,指引未来发展方向。

研究方法:

首先按照工艺组合方式的不同,将冲锻工艺进行分类,然后对每一类工艺列举典型的成形方法并进行讨论,包括其工艺特点,优缺点、适用范围、存在的问题等。基于全部的工艺进行归纳总结,指出冲锻工艺领域未来发展方向。

结果:

1) 板冲锻适合制造具有结构单元的板型零件;

2) 相对于传统的锻造或冲压工艺,板冲锻成形中模具压力非常高;

3) 相对于传统的锻造或冲压工艺,摩擦对金属流动影响显著;

4) 相对于传统的锻造或冲压工艺,模具或者设备动作相对复杂;

5)目前,针对高强度材料冲锻成形工艺较少。

结论:

1)冲锻成形工艺是制造具有功能单元板型件的有效方法,按照工艺组合方式的不同可以分为复合成形和板锻成形两大类;

2)板冲锻中,模具承受压力非常大,需要开发更高强度的模具材料来满足工艺的需要;

3) 板冲锻中,摩擦对金属流动影响显著,需要新的润滑技术和材料流动控制技术;

4)板冲锻中,模具动作相对复杂,因此需要能实现更多动作的新型智能设备;

5)随着轻量化的需求,高强度材料应用越来越广,需要开发出适合于高强度材料成形的冲锻工艺。
