Abstract
The invention provides a kind of heat treatment method of safety and firing mechanism bar, comprise the following steps：1) bar material is pressed into given size machine-shaping；2) qualitative processing, storage are carried out to bar using vacuum.The present invention carries out qualitative processing in vacuum drying oven, it is to avoid because of oil bath furnace overtemperature cause fire accident；Bar is put into technique box placed into vacuum drying oven and be heat-treated, it is to avoid damaging or deforming occur in operation in bar；Iron plate frock need not be used in processing procedure, it is not required that pay close attention to oil bath furnace temperature at any time, it is simple to operate；Bar need not be cleaned after the completion of qualitative processing, save cleaning cost.
Description
Technical field
The present invention relates to a kind of heat treatment method, and in particular to a kind of heat treatment method of safety and firing mechanism bar.
Background technology
Bar is the important component of certain model safety and firing mechanism, it is necessary to carry out qualitative processing to bar after machining shaping,
To eliminate its internal stress, the purpose of sizing is reached.Traditional process is to carry out qualitative processing using oil bath furnace, i.e., first use vapour
Oil cleaning part, dries；Oil bath furnace is warming up to after 250 DEG C, barre is put into stove, room temperature is air-cooled to again after insulation 4h.At this
Iron plate frock is needed to use during individual qualitative processing；Also need to pay close attention to oil bath furnace temperature at any time, in case overtemperature is on fire.In behaviour
It is easy to make during work to also need to carry out cleaning of deoiling to bar after the completion of part injury or deformation, and qualitative processing.
Safety and firing mechanism is in action, and the sliding block on bar needs slide downward.If bar is unqualified, it can cause to slide
Block does not glide, and safety and firing mechanism failure, final body is unable to normal detonation.
The content of the invention
In order to solve the above technical problems, the invention provides a kind of heat treatment method of safety and firing mechanism bar, the safety
The heat treatment method of actuator stem uses technique box by carrying out qualitative processing in vacuum drying oven, solves oil bath furnace
The problem of temperature overtemperature is on fire and part is easily damaged or deformed in operation.
The present invention is achieved by the following technical programs.
A kind of heat treatment method for safety and firing mechanism bar that the present invention is provided, comprises the following steps：
1) bar material is pressed into given size machine-shaping；
2) qualitative processing is carried out to bar using vacuum, specific process step is：
1. design technology box；
2. bar is cleaned and dried with gasoline；
3. bar is placed in technique box, be at ambient temperature put into bar in vacuum drying oven together with technique box；
4. vacuum drying oven is warming up to 250 ± 10 DEG C, and is incubated vacuum in 3h, stove and maintain 10—3Pa；
5. it is furnace-cooled to after less than 100 DEG C and bar is come out of the stove together with technique box；
6. bar is air-cooled to room temperature together with technique box.
3) bar is taken out from technique box, be put in storage.
The material of the bar is 9Cr18.
The step 2) in the lid that matches by box body and with box body of technique box be assembled.
Be put in storage again after sealing bar with phone paper bag in the step (3).
The beneficial effects of the present invention are：Qualitative processing is carried out in vacuum drying oven, it is to avoid cause because of oil bath furnace overtemperature
Fire accident；Bar is put into technique box placed into vacuum drying oven and be heat-treated, it is to avoid bar is damaged in operation
Or deformation；Iron plate frock need not be used in processing procedure, it is not required that pay close attention to oil bath furnace temperature, side simple to operate at any time
Just；Bar need not be cleaned after the completion of qualitative processing, save cleaning cost.
Brief description of the drawings
Fig. 1 is the structural representation of present invention process box；
Fig. 2 is the structural representation of bar of the present invention；
In figure：1- box bodys, 2- lids.
Embodiment
Be described further below technical scheme, but claimed scope be not limited to it is described.
A kind of heat treatment method of safety and firing mechanism bar, comprises the following steps：
1) material that bar is selected is 9Cr18, and the bar material is pressed into given size machine-shaping；
2) qualitative processing is carried out to bar using vacuum, specific process step is：
1. design technology box, as shown in figure 1, the lid 2 that technique box matches by box body 1 and with box body 1 assemble and
Into；
2. bar is cleaned and dried with gasoline；
3. bar is placed in technique box, be at ambient temperature put into bar in vacuum drying oven together with technique box；
4. vacuum drying oven is warming up to 250 ± 10 DEG C, and keeps vacuum in 3h, stove to maintain 10—3Pa；
5. it is furnace-cooled to after less than 100 DEG C and bar is come out of the stove together with technique box；
6. bar is air-cooled to room temperature together with technique box；
3) bar is taken out from technique box, storehouse is enclosed with phone paper bag.
The present invention carries out qualitative processing in vacuum drying oven, it is not necessary to pays close attention to oil bath furnace temperature at any time, it also avoid because of oil bath
Stove overtemperature and cause fire accident；The special technique box of design, the box-shaped structure is simple, designs, processes and using very
It is convenient；Bar is put into place into vacuum drying oven in technique box and is heat-treated, it is to avoid bar occur damaging in operation or
Deformation；Iron plate frock need not be used in processing procedure, it is simple to operate；Safety and firing mechanism is avoided in action,
Because bar is unqualified, and sliding block is caused not glide, safety and firing mechanism failure, the problem of final body is unable to normal detonation.
Bar need not be cleaned after the completion of qualitative processing, save cleaning cost, improve production efficiency.
