Description
Technical field
The invention belongs to be hot-forged tooling field, specially a kind of versatility combined type die forging tooling.
Background technique
The die forging degree of automobile industry is higher, such as planetary gear, sun gear, the differential mechanism of automobile are all made of precision
Die forging production walks forging at home using forward position.Weapons industry, aerospace also have Some Enterprises raw using precision die forging technology
Forging blank is produced, and has achieved good economic benefit, but is small compared to automobile industry on the whole, mainly by product
Multiplicity, batch is small, Mold Making is at high cost, and the objective factors such as strong, mould handling inconvenience do not constrain forging to mold interchangeability
It is applied on press machine.Therefore, open die forging or common swaging technique are generallyd use during processing and manufacturing, forging it is micro-
Microstructure and mechanical property is low compared to precision die forging, and machine adds surplus big, and processing efficiency is low, and stock utilization is low, and manufacturing cost is high, produces
Product surface quality is poor.
With the demand for development of lean production, green manufacturing, precision die forging technology is developed, except the ton of equipment itself
Position limitation, die cost and traditional mold design mode make the forging of only small range size be suitble to certain equipment, equipment
Investment also constrains the development of precision die forging technology.
It is thus impossible to using traditional mold design mode, it is necessary to solve Mold Making, maintenance cost, mold versatility,
The problems such as mold quick despatch, product size covering scope.
Summary of the invention
The purpose of the present invention is can be used for producing certain in view of the above problems, provide a kind of versatility combined type die forging tooling
