Abstract
The invention discloses a production process of a high-speed steel moldboard plow structure. The production process comprises the following steps: smelting and pouring: waste ends of high-speed steel, waste cutters and water chips are remelted in a circuit; a certain quantity of alloy elements is added in the circuit in the smelting process; the pouring for casting the high-speed steel adopts a method of high-temperature furnace discharge and low-temperature pouring; the furnace discharge temperature of W18Cr4V steel is 1570-1550 DEG C; and the pouring temperature is 1480-1460 DEG C; mold casting: the sand mold casting and the fired mold precise casting are adopted, or the ceramic and metal casting is adopted; and heat treatment: before a cast moldboard plow is machined, the annealing firstly performed to eliminate internal stress of the cutters; and the annealing temperature is 950-980 DEG C, and is higher than the annealing temperature of rolled or forged steel. The production process is simplified, saves labors, and largely reduces the tool cost.

Mouldboard plow is the farm implements in a kind of arable land, generally ties up to, on one group of its motor vehicles of traction, be used for crushing soil block upturned soil
Overturn and plough out groove thus prepare for sowing.Plough body is the main working parts of plough, typically by ploughshare, mouldboard, landside
And the composition such as plow standard, plowshoe, U-shaped fastened on plow frame girder with threaded by plow standard top planes.Ploughshare and mouldboard
Collectively constitute the working curved surface of plough, play and cut soil and turn over the effect of upturned soil, from work for be an entirety.Due to ploughshare during work
Bearing bigger load, abrasion is relatively big, affects work, needs to improve this and perfect.
Summary of the invention
It is contemplated that overcome the defect of prior art, it is provided that a kind of high-speed steel mouldboard plow structure and production technology thereof, letter
Metaplasia production. art, saves the amount of labour, significantly lowers the cost of instrument.
In order to solve above-mentioned technical problem, the invention provides following technical scheme:
The production technology of a kind of high-speed steel mouldboard plow structure, comprises the steps, melting and cast, by high-speed steel waste material head, gives up
The remelting in circuit of cutter and scrap obtains；In circuit, a certain amount of alloying element is added in fusion process；Casting is at a high speed
The cast of steel uses high temperature to come out of the stove, the method for cast cold, and the tapping temperature of W18Cr4V steel is 1570-1550 DEG C, pouring temperature
For 1480-1460 DEG C；
Casting mold, uses sand casting and precision-investment casting, or uses ceramic mould, permanent mold casting；
Heat treatment, casting high speed steel mouldboard plow before processing, first carries out annealing and eliminates the internal stress of cutter, and annealing temperature is 95
0-980 DEG C, higher than rolling or the annealing temperature of forged steel.
Further, wherein in heat treatment process, mouldboard plow is incubated under higher than normal quenching temperature strip, passes through carbide
Reunion make ledeburite reach granulation.
Further, high-speed steel mouldboard plow structure, fix including ploughshare, mouldboard, landside, plowshoe, plow standard, ploughshare and mouldboard
On plowshoe, ploughshare and mouldboard constitute the fixing connection of working curved surface, plow standard and plowshoe, and plowshoe is a connecting piece, ploughshare, plough
Wall, landside, plow standard composition plough body assembly.
Further, plowshoe high-speed steel plate is stamped to form, or welding or casting form.
Further, plowshoe and plow standard are made integral.
Further, plow standard is the Force transmission parts of plough, and plow standard is open circles or oval directly plow standard or the solid curved plough of flat high-speed steel
Post.
Compared with prior art, the present invention has a following beneficial effect:
The present invention uses casting method to produce the remelting recycling that can realize high-speed steel waste material, to improve stock utilization, simplifies
Production technology, saves the amount of labour, significantly lowers the cost of instrument.When using sand casting and hot investment casting, the utilization rate of material
Can reach 65% and more than 85%.
