Abstract
A kind of heat treatment method of straight screwdriver, it is characterised in that：The technique includes following steps：（1）The material of straight screwdriver head is according to percentage by weight, and the carbon content of carbon spring steel is 0.62% 0.90%, and manganese is containing 0.50% 0.80%, and silicone content 0.50% 0.65%, surplus is inevitable impurity.（2）The material for determining formula is mixed, mixture is milled into powder, then material hot forging is made the screwdriver rod of setting length, it is standby.（3）Go out the steps such as " one " word shape with lathe tool hot forging at the cutter head of knife bar, a kind of heat treatment method of straight screwdriver of the present invention, it is unlikely to deform screwdriver, the fatigue resistance of screwdriver is enhanced, intensity is good, makes product firmly without crisp, have in crisp tough, convenient use, the physical life of product is enhanced, save the cost of buyer.
Description
Technical field
The present invention relates to technical field of heat treatment, more particularly to a kind of heat treatment method of straight screwdriver.
Background technology
Screwdriver is a kind of very common hand tools, for twisting screw to force its instrument in place, generally
Have a thin sphenocephaly, can be inserted into the line of rabbet joint or recess of screw cap, the important indicator of straight screwdriver be the intensity of material,
Toughness and antifatigue degree, it can not only reflect the quality of the indices of straight screwdriver, moreover it is possible to reflect between each performance
Best match and by influence of the matching between this performance to the service life of straight screwdriver.Wherein, straight screwdriver
Inherent quality and fatigue resistance have it is very big associate, and deformed using cutter head will not occur for a long time, or damaged shape
Condition, it can not be continuing with.
The content of the invention
The purpose of the present invention is shortcoming present in solution background technology, there is provided a kind of heat treatment side of straight screwdriver
Method.
A kind of heat treatment method of straight screwdriver, it is characterised in that：The technique includes following steps.
（1）The material of straight screwdriver head is that the carbon content of carbon spring steel is in 0.62%- according to percentage by weight
0.90%, manganese contains 0.50%-0.80%, silicone content 0.50%-0.65%, and surplus is inevitable impurity.
（2）The material for determining formula is mixed, mixture is milled into powder, setting length then is made in material hot forging
Screwdriver rod, it is standby.
（3）Go out " one " word shape with lathe tool hot forging at the cutter head of knife bar.
（4）Heated under 600-800 degree celsius temperatures 1 to 2 hour, it is then whole with heat under 150-200MPa pressure in mould again
Shape, burnt under 1250-1350 degrees Celsius and be incubated 1 to 3 hour, then divide the two-stage to cool, the cooling speed of first stage
Degree is maintained at 5-8 centigrade per minutes, and 1-3 hours are tempered when temperature drops to 500-550 degrees Celsius, are then cooled to
200 degrees centigrades, obtain straight screwdriver head.
（5）By above-mentioned base substrate in 780-800 degrees Celsius of glowing furnace inside holding 2 hours, Quenching Treatment is carried out, is taken the photograph using 230
Room temperature is naturally cooled to after the constant temperature salt bath quenching of family name's degree or so to insulation 2-4 hours after 250 degrees Celsius, obtains electric screw driver
Cutter head semi-finished product.
（6）Then it is placed in oxygen atmosphere and carries out reduction reaction, and polished, removes the carbon thing in knife bar and cutter head
Matter.
（7）Then it is immersed in 30% aluminium hydroxide and the mixed solution of sodium fluoride, 2 days time, clear water washes down, and obtains
Finished product screwdriver.
Beneficial effect of the present invention：A kind of heat treatment method of straight screwdriver of the present invention, is unlikely to deform screwdriver,
The fatigue resistance of screwdriver is enhanced, intensity is good, makes product firmly without crisp, there is tough, convenient use in crisp, enhances the reality of product
With the life-span, the cost of buyer is saved.
Embodiment
