Description
Technical field
The invention belongs to technical field of forging, more particularly to a kind of stainless steel knife forging technology.
Background technology
With the development of China's mechanical industry, cutting speed and feed are increasingly improved in machining, due to friction
Effect, the unit interval produce heat it is also more and more, sometimes blade heating temperature reaches more than 600 DEG C, but also holds
Cutting pressure is received, in this case, cutter is still to holding hardness high, intensity and wearability, must be requested that shear steel
The continuous improvement of the combination property of material.For the mechanical performance of cutter, manufacturability has a strong impact on.
The content of the invention
It is an object of the invention to provide a kind of stainless steel knife forging technology, solve and asked present in prior art
Topic.
To solve above technical problem, the present invention provides following technical scheme：A kind of stainless steel knife forging technology, including
Following steps：
A. embryo material prepares, and selects low carbon high alloy stainless steel ingot casting；
B. low carbon high alloy stainless steel ingot casting is put into carries out first time heating and insulation in heating furnace, first time heating-up temperature
580 DEG C are should be less than, then the control of first time firing rate be incubated in≤80 DEG C/H at 850 DEG C；
C. the low carbon high alloy stainless steel ingot casting of preheating is heated to 1130~1180 DEG C of temperature, is put into forging mould
Forged, initial forging temperature is 1050~1100 DEG C, 880-930 DEG C of final forging temperature, stop forging 800-900 DEG C of temperature；
D. air cooling, 20-30 DEG C of cooling velocity/h；
E. forging cutter blank is taken out, carries out deburring.
Preferably, the forging mold is first preheating to 400 DEG C before forging.
Beneficial effect of the present invention：Forging technology of the present invention is simple, and it is uneven to improve carbide, improve wearability and
The combination properties such as toughness, improve processing efficiency, reduce production cost.
Specific embodiment
The present invention will be further described in conjunction with the embodiments.
