模具铸铁刃口堆焊


打开文本图片集

摘 要:在汽车模具里,把堆焊技术应用于修边刃口的焊接,应用于拉延模和成形模的拉延筋或磨损面的堆焊,可以大大降低模具制造成本和制造周期,便于模具的维修制件精度的提高,在铸件的表面堆焊一层耐磨材料,焊层硬度可以达到HRC55左右,从而满足模具的刃口修边或拉延成形的工艺要求。

Die Cast of Iron Cutting Edge Surfacing

Peng Yongjun

Abstract:In automobile molds, the application of surfacing welding technology to the welding of trimming edges, to the surfacing of the drawing bead or wear surface of the drawing die and the forming die, can greatly reduce the mold manufacturing cost and manufacturing cycle, and improve the precision of mold repair parts. A layer of wear-resistant material is deposited on the surface of the casting, and the hardness of the welding layer can reach about HRC55, so as to meet the process requirements of cutting edge trimming or drawing forming of the mold.

Key words:surfacing, cracks, quenching
