AI Technical Summary

Technical Problem

The existing method of remelting scrap from gear forging leads to energy waste, introduction of impurities, impure composition, and low production efficiency. Furthermore, defects such as incomplete filling, folding, and cracking occur during the pre-forging process, affecting the quality and cost of the finished product.

Method used

The equipment used for gear forging production includes a waste collection module, a powder preparation module, and an extrusion bar module. Forging waste is collected, crushed, ground, impurities removed, cleaned, dried, and graded and screened to prepare mixed metal powder. The powder is then pressed into pre-forged billets by the extrusion bar module, thus achieving high-value recycling of waste.

Benefits of technology

Significantly reduce energy consumption, improve material utilization, enhance filling performance and forming quality during forging, improve the mechanical properties and service life of finished gears, and reduce production costs.

Abstract

This invention provides a pre-forging equipment and method for gear forging production, relating to the field of gear forging technology. It includes a waste collection module, a powder preparation module, and an extrusion bar module, as well as a circulation control module electrically connected to each of these modules. The waste collection module is used to classify and collect waste generated before and after gear forging, and then transport the waste to the powder preparation module. The powder preparation module is used to sequentially crush, grind, remove impurities, clean, dry, and classify the received forging waste to prepare a metal mixed powder, which is then transported to the extrusion bar module. The extrusion bar module is used to press the metal mixed powder filled in the die cavity into pre-forged billets of a preset specification, achieving high-value recycling of gear forging waste, replacing the traditional remelting method, significantly reducing energy consumption and metal loss, improving material utilization, and significantly reducing production costs.
