Novel formation process of flywheel of engine

Abstract

The invention relates to the technical field of metal mechanism processing, and in particular relates to a novel formation process of a flywheel of an engine. The process is that a cold plastic processing process is carried out; round steel is used as a raw material and processed by horizontally rotating; the processed blank is positioned into a horizontal rotating die; a hub and a spoke of the flywheel are formed by the horizontal rotating process; meanwhile, a rim of the flywheel is formed through an external two-way guide wheel; therefore, the static balancing requirement can be met; a large amount of processes can be saved; the turning processing is avoided; materials can be saved; meanwhile, the problems of high pollution, high energy consumption and high emission in cast production can be solved.

Description

Technical field [0001] The invention relates to the technical field of metal machining, in particular to a new process for forming an engine flywheel. Background technique [0002] The flywheel is a part of the disc hub. The flywheel is mainly used for energy absorption and release in the mechanical drive train of the engine. It is an indispensable energy storage part. In the traditional manufacturing process, the ordinary flywheel is mainly HT250 and other castings. The blank is cast through the casting process. After turning processing, balancing and other processes are completed, a lot of materials are wasted, the production cost is increased, and the flywheel is heavier and prone to cracking. At the same time, casting production involves high energy consumption, high pollution and high cost due to high temperature smelting and casting process. Its industry capacity and scale have been regulated and restricted by the state. Although the current casting process can meet the re...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is: in order to overcome the fact that the flywheel in the prior art casts the blank through the casting process, and then completes the process of turning, balancing and other processes, a large amount of material is wasted, the production cost is increased, and the flywheel is heavy and easy to crack; the blank After turning, the static balance requirements cannot be met, and static balance and multiple drilling and weight removal processes must be added; and casting production involves many problems such as high energy consumption, high pollution and high cost due to high-temperature smelting and casting processes. The present invention provides A new process for forming an engine flywheel, which adopts a cold plastic processing process, uses round steel as a blank, and puts the processed blank into a flat-rotation mold through the flat-rotation forming step, and completes the hub and spoke of the flywheel through the flat-rotation process At the same time, the forming of the rim of the flywheel is completed through the external two-way guide wheel, which meets the requirements of static balance, saves a lot of processes, does not need turning processing, saves materials, reduces production costs, and also solves the problem of high casting production. Pollution, high energy consumption and high emissions issues
