Description
Technical field
The present invention relates to a kind of blade Technology for Heating Processing, more particularly to a kind of mowing blade Technology for Heating Processing.
Background technology
Mowing blade cuts the grass on a lawn for hay mover, vegetation etc., and it is made up of retainer plate, cutter hub, blade.Retainer plate is used
To be arranged in rotating shaft, motor is rotated so as to be rotated at a high speed with cutting blade, saves the activity duration of weeding worker, is reduced big
The human resources of amount.But in face of situation complicated lawn or field, a large amount of stones and tree root are especially in the presence of, were used in the past
Blade is not possessing sharp, blade occurs and bursts apart, causes personnel labor intensity big, and equipment cost is high.
The content of the invention
【1】Technical problems to be solved
The technical problem to be solved in the present invention is to provide a kind of high intensity, high rigidity and good toughness, keen edge are hard
Gu and durable mowing blade Technology for Heating Processing.
【2】The technical scheme solved the problems, such as
The present invention provides a kind of mowing blade Technology for Heating Processing, and material is that 1Cr13 ladles include chemical composition：Carbon：Less than etc.
In 0.15；Manganese：Less than or equal to 1；Silicon：Less than or equal to 1；Chromium：11.50~13.50；Phosphorus：Less than or equal to 0.030；Sulphur：It is less than or equal to
0.030；Other：Less than or equal to 0.60；Its Technology for Heating Processing comprises the following steps：
A1 normalized treatments：Workpiece be heated in stove temperature for 727~912 DEG C when, be incubated 10~20 minutes, workpiece is come out of the stove
After be placed in natural cooling in air, change metal inside composition composition, strengthen mechanical performance；
A2 is quenched and temper：Workpiece be heated in stove temperature for 927~1000 DEG C when, be incubated 10~30 minutes,
Workpiece is put into oil after coming out of the stove and cooled down, high rigidity, good wearability, reduces fragility；
A3 carbo-nitridings：Workpiece is first to heat to when temperature is 900~950 DEG C in stove and is cooled to 500~570 after carburizing
DEG C, 1~2 hour is incubated, oil cooling after coming out of the stove, improves steel object surface hardness and fatigue resistance；
A4 Passivation Treatments：Workpiece be placed in passivating solution be heated to temperature for 30~40 DEG C when, soak 3-20 minutes or more
When long, blade fine cracks opening is removed.
Further, the Passivation Treatment forms uniform passivation process film in knife face, slows down tool wear.
【3】Beneficial effect
Mowing blade Technology for Heating Processing of the present invention, intensity, hardness and toughness are improved, strengthen surface abrasion resistance, keen edge
It is firm and durable.
Embodiment
The present invention is described in detail below.
The present invention provides a kind of mowing blade Technology for Heating Processing, and its material is that 1Cr13 ladles include chemical composition：Carbon：It is less than
Equal to 0.15；Manganese：Less than or equal to 1；Silicon：Less than or equal to 1；Chromium：11.50~13.50；Phosphorus：Less than or equal to 0.030；Sulphur：Less than etc.
In 0.030；Other：Less than or equal to 0.60；Its Technology for Heating Processing comprises the following steps：
A1 normalized treatments：Workpiece be heated in stove temperature for 727~912 DEG C when, be incubated 10~20 minutes, workpiece is come out of the stove
After be placed in natural cooling in air, homogenize crystal grain refinement and distribution of carbides, remove the internal stress of material, stable workpiece
Size, prevent deformation and cracking；
A2 is quenched and temper：Workpiece be heated in stove temperature for 927~1000 DEG C when, be incubated 10~30 minutes,
Workpiece is put into oil after coming out of the stove and cooled down, and to improve hardness, wearability, reduces fragility；
A3 carbo-nitridings：Workpiece is first to heat to when temperature is 900~950 DEG C in stove and is cooled to 500~570 after carburizing
DEG C, 1~2 hour is incubated, oil cooling after coming out of the stove, improves the case hardness of steel, wearability and fatigue strength；
A4 Passivation Treatments：Workpiece be placed in passivating solution be heated to temperature for 30~40 DEG C when, soak 3-20 minutes or more
When long, uniform passivation process film is formed in knife face, takes out after the completion of processing, is rinsed well with clear water, preferably use buck or stone again
Buck, which rinses, to be neutralized, and is removed the microcosmic breach of cutting edge roundness and is slowed down abrasion.
Mowing blade Technology for Heating Processing of the present invention, intensity, hardness and toughness are improved, strengthen surface abrasion resistance, keen edge
It is firm and durable.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvements and modifications can also be made, these improvements and modifications
Also it should be regarded as protection scope of the present invention.
