Abstract
The invention relates to a heat treatment method of a high speed steel tool used for military, which comprises the following steps: S100) quenching a tool blank through forging and moulding in a quenching medium at the temperature of 1500-1600 DEG C; S200) naturally cooling the quenched tool blank to the room temperature; S300) tempering for 2-3 hours at low temperature of 100-150 DEG C in a same medium in the S100); S400) cooling the tool blank through tempering at the low temperature of -120--80 DEG C for 4-5 hours; and S 500) tempering the tool blank tempered in the step S400) between the temperature of 500-600 DEG C for 1-2 hours and naturally cooling to the room temperature. By employing the above technical scheme, the heat treatment method performs the relatively simple heat treatment on the tool based on the condition of no change of the current cutter material, each performance of the tool is greatly increased, the method is simple and feasible, the cost is low, and the method is suitable for popularization and application in a large scope.
Description
Technical field
The present invention relates to a kind of tool heat treatment method, relate in particular to a kind of military high speed steel tool heat treatment method.
Background technology
Along with the raising of living standards of the people, increasing people start to hanker after field exploration, also increasing to the demand of field survivorship cutter.Along with the popularization of doomsday Movies, occur that a class is known as the people of " surviving mad ", they will store the goods and materials such as tap water and army provisions at ordinary times at home, for the necessary military cutter of field survivorship, one of staff especially, even, for different demands, everyone can store much knives tool.
Qualified, even outstanding military speedy steel cutting-tool is except materials selection has very dark being particular about, the thermal treatment of cutter, and the intensity to cutter, hardness, toughness all have a great impact.
Summary of the invention
The present invention is directed to the proposition of above problem, and the military high speed steel tool heat treatment method of one of development comprises following steps:
S100. by the cutter blank of forging molding, be, at the temperature of 1500 DEG C-1600 DEG C, in quenchant, to quench in temperature;
S200. the cutter blank after quenching is naturally cooled to room temperature;
S300. in the same media described in described S100, low-temperaturetempering 2-3 hour at 100 DEG C-150 DEG C of temperature;
S400. by the cutter blank deepfreeze 4-5 hour under the condition of-120 DEG C ~-80 DEG C through low-temperaturetempering;
S500. by the cutter blank through step S400 low-temperaturetempering between 500 DEG C-600 DEG C tempering 1-2 hour and naturally cool to room temperature.
Described heat-eliminating medium is water base cooling fluid.
In the time that cutter blank is Cr12MoV steel, described each step is specially:
S100. by the cutter blank of forging molding, be, at the temperature of 1500 DEG C, in quenchant, to quench in temperature;
S200. the cutter blank after quenching is naturally cooled to room temperature;
S300. in the same media described in described S100, low-temperaturetempering 2 hours at 150 DEG C of temperature;
S400. by through the deepfreeze 5 hours under the condition of-100 DEG C of the cutter blank of low-temperaturetempering;
S500. by the tempering 2 hours naturally cool to room temperature between-600 DEG C of the cutter blank through step S400 low-temperaturetempering.
Owing to having adopted technique scheme, the military high speed steel tool heat treatment method of one provided by the invention, do not changing on the basis of existing cutter material, cutter is carried out to relative brief heat treating, promote greatly the properties of cutter, due to method simple possible, old cheap, very applicable large-scale promotion and application.
