The invention relates to a protection device and method for a one-time product forming process of automobile electromagnetic damping parts. One-time manufacturing from raw materials to a finished product is achieved through a series of technological processes including die prefabricating, raw material preparing, high-pressure one-time forming, high-temperature sintering in a nitrogen-filled sintering furnace, rapid air cooling, rolling polishing, coating, inspecting and packaging, traditional machining processes such as machine drilling and grooving are omitted, and the technological difficulties which are inconvenient to operate and even cannot be operated during traditional metal part machining are solved at a time; The protection device and method have the beneficial effects of being safe, high in efficiency, simple in process, high in precision and low in defective rate and reducing cost in a doubled manner; and the physical and chemical properties such as hardness, density, smoothness, wear resistance and corrosion resistance of the manufactured finished product are superior to those of a metal piece sintered by a common sintering furnace.
Description
technical field [0001] The invention relates to the field of manufacturing techniques and methods of automobile metal parts, in particular to a protection device and method for a primary finished product process of automobile electromagnetic shock absorbing parts. Background technique [0002] Most of the traditional metal parts manufacturing process adopts forging or casting method, which melts the metal raw materials at high temperature and makes them into blanks, and then processes them into the required shape and size specifications of metal parts through machinery and equipment, but there are some special-shaped structures of some metal parts. The horns and corners are inconvenient or even impossible to process. At the same time, there are many problems such as cumbersome process, a lot of equipment, high temperature danger in the production process, waste generated during processing, and frequent industrial accidents. [0003] In view of this, our company scientifical...
