For streetcar, racing cycle motorcycle, cross country motorcycle, cruise car, station wagon etc..
Essential element of the lower linking plate as current motorcycle, mostly cast iron quality, because its exterior appearance is complicated, therefore make
The technique of standby production is also complex.It is big that hardness deficiency, hardness scattered error usually occurs in the lower linking plate prepared at present with prior art
Or hardness it is uneven the problems such as, and production technology heat treatment step cost is high at present, energy consumption is big, has the defects of larger.
Patent Office of the People's Republic of China disclosed a kind of patent of invention of the production technology of motorcycle lower link plate on 03 19th, 2014
Application documents, application publication number CN103639647A, the patent of invention provide a kind of preparation technology of motorcycle lower link plate,
Including steps such as manufacture early stage, forging forming, heat treatment, ball blast, flaw detection and rust prevention packagings, mould is strengthened in terms of hardness
Performance, but do not improved in terms of uniformity of hardness, easily produce hardness scattered error, and the heat treatment side that the patent of invention provides
Formula still suffers from the problem of energy consumption is big, cost is high.
The content of the invention
To solve, usually there is hardness deficiency in the above-mentioned lower linking plate prepared with prior art, hardness scattered error is big or hardness is uneven
The problems such as even, and production technology heat treatment step cost is high at present, energy consumption is big, has the problem of the defects of larger, the present invention
Provide that a kind of lower linking plate hardness scattered error prepared is small, uniformity is high and the motorcycle lower link plate production compared to prior art
Technique single-piece energy consumption declines about 55%, and cost per unit declines the energy-saving processing technique of about 56% motorcycle lower link plate.
To achieve the above object, the present invention uses following technical scheme：A kind of energy-saving processing technique of motorcycle lower link plate,
The production technology includes：
1）Mould manufacture early stage, prepares for forging and stamping early stage；
2）Forging forming, second line of a couplet board finished product will be forged into；
3）Quantity-produced improves heat treatment, lifts the hardness of lower linking plate, improve its uniformity of hardness reduce hardness scattered error and
Save energy consumption；
4）Water is quick-fried, removes the oxide skin formed by forging and stamping heating in second line of a couplet plate surface；
5）Flaw detection, it is ensured that product surface flawless；
6）Antirust treatment, prevent from getting rusty；
Wherein step 1）Mould early stage manufacture includes mould steel being machined to pier mold, shaping mould and edger and right
Pier mold, shaping mould and edger are heat-treated, step 2）Forging forming includes blanking, heating, pier base, shaping and trimming,
Step 3）The heat treatment carried out to pier mold, shaping mould and edger, the heat treatment improve heat treatment, institute for quantity-produced
State step 4）Descale mode is that water is quick-fried, and quantity-produced improves heat treatment and comprised the following steps：
a）Heating quenching, cool time 60-80min are carried out to mould under the conditions of 900-930 DEG C；
b）Cooling Quenching is carried out under 25-35 DEG C, 0.2-0.4MPa hydraulics；
c）Mould after oil cooling is once tempered at 170-190 DEG C, tempering time 150-180min；
Wherein quantity-produced, which improves, is heat-treated the quenching technical using line-frequency induction is diathermanous, oil groove quenches and meshbeltfurnace tempering
Process route.
Preferably, die workpiece is higher than mould with horizontal direction vertically into liquid level during the progress Cooling Quenching operation
In the quenching medium of workpiece top.
Preferably, the quenching medium is the mixed liquor of the poly- alkylene ethylene glycol of water-soluble quenching medium and water.
Preferably, mass fraction of the poly- alkylene ethylene glycol in the quenching medium is 5-10%.
Preferably, the defects detecting technology using ultrasonic inspection carry out, the antirust treatment include polishing, overlay film, plating,

The mould that traditional glowing furnace heat treatment mode handles to obtain has the shortcomings that hardness scattered error is big, hardness is uneven, main
If even caused due to heating uneven or quenching inhomogeneous cooling, due between the diathermanous heating component of power frequency and inductor
Gap uniformity, electric current and voltage constant, heat time are accurately controlled by relay, the temperature fluctuation under temperature measuring device monitoring
Scope is minimum, in positive and negative five degrees Celsius of error range, compared to the temperature that traditional glowing furnace produces several tens easily
Fluctuating error, the diathermanous mode of heating of line-frequency induction can greatly improve thermal-stable, largely avoid due to adding
Hardness scattered error caused by heat is uneven is big and the problems such as hardness inequality.Dipped down additionally due to workpiece need to pass through from furnace outlet
Oblique downslide pipeline falls into oil groove, is to enter oil with an inclined angle when falling into quenching oil, is also by bottom during cooling
Top gradually is arrived, therefore can not accomplish that the cooling of relative synchronization is compared at each position in cooling procedure, therefore quenches the equal of cooling
Even property is poor, and die workpiece is higher than mould work with horizontal direction vertically into liquid level during progress Cooling Quenching operation in the present invention
In the quenching medium on part top, it can ensure that the cooling of relative synchronization is compared at each position, improve the uniformity of cooling.
It is above-mentioned to instead of traditional glowing furnace using the heat treatment route that line-frequency induction is diathermanous, oil groove is quenched and meshbeltfurnace is tempered
Route is heat-treated, thermal-stable, uniformity and the cooling uniformity in cooling procedure of mould can be greatly improved, is ensured
Each position can carry out the strong cooling of relative synchronization, substantially reduce the hardness scattered error of mould, improve hardness
Uniformity.
And it is heat-treated with heat treatment method provided by the present invention, can compared to traditional heat treatment method
Greatly reduce energy consumption.
The technique that the scale removals such as traditional ball blast are substituted in the quick-fried method of water, can reduce die surface due to ball blast shape
Into damage, and can further save manufacturing cost, reduce energy consumption.
Compared with prior art, the beneficial effects of the invention are as follows：Using line-frequency induction is diathermanous, oil groove quenches and meshbeltfurnace returns
The heat treatment route of fire instead of traditional glowing furnace heat treatment route, can greatly improve thermal-stable, the uniformity of mould
With the cooling uniformity in cooling procedure, ensure that each position can carry out the strong cooling of relative synchronization, subtract significantly
The small hardness scattered error of mould, improve the uniformity of hardness；Compared to traditional heat treatment method, energy can be greatly reduced
Consumption.
