Problems solved by technology

[0002] At present, according to the actual production verification, the production date of stamping products is stamped, and the riveting process of seat products needs to use the riveting machine device. The riveting machine device in the prior art cannot meet the simultaneous process of lettering and riveting. Requirements increase the working intensity of the staff, and most of the press riveting machines in the prior art are made of alloy materials, which will easily cause wear and corrosion under long-term use, reduce production efficiency and production quality, and greatly increase production. Cost, in order to improve this situation, improve work efficiency, save time and effort, high efficiency and energy saving, the present invention proposes a wear-resistant precision lettering riveting machine working device and its heat treatment process
