Description
Technical field
The invention belongs to field of mechanical technique, and in particular to a kind of forging technology of machinery forging.
Background technology
Forging can fast, easily make the blank part that is not much different with required part, with forge come blank part
Finish again, part production yields can be accelerated, be a kind of convenient and practical mode of production.
Forging technology is one of industrial important technology, is widely used in the fields such as Aeronautics and Astronautics, machinery, shipbuilding.
Forging technology is that one kind applies pressure using forging machinery to metal stock, it is produced plastic deformation to obtain with certain machine
The processing method of the forging parts of tool performance, definite shape and size.
But existing forging is after forging, there are the problem of surface smoothness is poor, finish is low, structural strength is insufficient, and
It is particularly important that heat treatment mode of forging influences the structural strength of forging.
The content of the invention
To solve the above-mentioned problems, the present invention provides a kind of forging technology of mechanical forging, and step is as follows：
(1) sorting：Select embryo material；
(2) heat：It is 1000~1500 DEG C that embryo material, which is sent into electric furnace to temperature, it is contemplated that temperature increasing by deformation, heating-up temperature
1000~1200 DEG C are taken as, pressure is applied to blank using metal forming machinery, produces plastic deformation so that it is internal loose thin
Crystal grain is compacted, so that reaching the tool performance for improving accessory；
(3) cool down：Cooldown rate is 45-50 DEG C/min；
(4) it is surface-treated：The melting that forging after cooling is put into design temperature is had in the coating bath of zinc so that accessory
Surfaces externally and internally all covers the zinc ion that can prevent surface oxidisation.
Preferably, electric furnace temperature is 1200 DEG C in the step (2).
Preferably, cooldown rate is 45 DEG C/min in step (3).
The beneficial effects of the invention are as follows：The difficulty and equipment cost of processing are reduced, production efficiency is higher, mechanical performance
It is good, it can meet the requirement of long-time service.
