Forging forming process for iron ornamental part product

Abstract

The invention relates to a forging forming process for an iron ornamental part product. According to the process, low-temperature warm forging pattern preforming is adopted to replace cold forging pattern preforming; moderate-temperature warm forging forming is adopted to replace traditional high-temperature forging forming; electrical heating is adopted to replace fire coal heating; and process flows and the preparation of a mold are reasonably standardized. Compared with the common traditional high-temperature heating forging, by adopting the warm forging forming technology, the surface quality and the heating efficacy of the iron ornamental part product can be remarkably improved, the heating oxidation loss of a material is reduced, and the workshop cost of forging after-treatment is greatly reduced. A low-temperature warm forging and moderate-temperature warm forging forming process is a novel forging forming process with both advantages of high-temperature forging forming and advantages of cold forging forming. According to the forging forming process for the iron ornamental part product, higher forging precision, higher material yield and higher heating and after-treatment efficacy are integrated, and thus, the technical content and the additional value of the iron ornamental part product can be beneficially improved.

Description

technical field [0001] The invention relates to a forming process of wrought iron decorative accessories. Background technique [0002] All kinds of wrought iron products, including assembled wrought iron balcony railings, pay special attention to the unity of functionality and aesthetics. For this reason, quite a number of wrought iron products are equipped with various decorative accessories with exquisite design and various patterns. The decorative accessories of most wrought iron products manufacturers are pre-formed by cold forging patterns and finally formed by traditional high-temperature forging. Die forging) → post-processing (grinding, iron sheet removal, etc.). [0003] Although high-temperature forging is easy and can be carried out on forging equipment of smaller tonnage (air hammer or press), the loss coefficient of the above-mentioned heating is generally higher than 1.025; the pressed-in area of ​​the oxide scale usually exceeds 20%, Subsequent processing ...

AI Technical Summary

Problems solved by technology

Cold forging helps to improve the surface quality of forgings, and the amount of follow-up processing is the lowest, but it puts forward very strict requirements on the power of the forging machine and the material of the mold, which will significantly increase the cost of the workshop
