Description
The utility model relates to the soldering Equipment for Heating Processing of heat-treating blade, cutlery in the tool industry.
At present, produce blade, the employed soldering Equipment for Heating Processing of cutlery in the tool industry, level is extremely backward, is fuel oil, combustion gas or electrically heated direct-fired heater.Because there is not protective atmosphere, product is in heating process, and not only oxidation is serious, and heats inhomogeneously, and quenching technical falls behind, and the back blade deflection that quenches is big, and percent defective is up to 40-50%, and product quality is also extremely unstable.
In view of the blade in the above-mentioned tool industry, cutlery Equipment for Heating Processing backward state, be badly in need of developing a blade with international most advanced level, cutlery Equipment for Heating Processing-push away chain type controlled atmosphere soldering heat-treatment furnace has been the task of top priority.
The purpose of this utility model be exactly conceive in order to provide a kind of that science novelty, design unique and beautiful, technology rationally are suitable for, properties of product are reliable, percent defective is low, automaticity is high, easy to operate, blade cooling evenly, cooldown rate can arbitrarily control, obtain desirable grain structure, reduce labor strength, take that porous sprays liquid nitrogen push away chain type controlled atmosphere soldering oven.
The purpose of this utility model is achieved in that whole device is by heating clamber, Elema, refractory fibre, the furnace pressure controller, temperature controller, seal closure, fire door, snap-chill cabinet, fan, furnace rolls, the fire door lifting device, the push-and-pull head, open kinematic chain, left side feeding platform, right feeding platform, the roller transmission mechanism, the liquid nitrogen spraying system, the carbon-potential control device, charging tray is formed, the Elema of heating is housed in the heating clamber, temperature controller and furnace pressure controller are housed on the furnace roof refractory fibre, the heating clamber side is equipped with the carbon-potential control device, the heating clamber right-hand member is by oven door sealing, seal closure with isolated outside air between heating clamber and the snap-chill cabinet seals, the fan of water-cooled circulation is installed at the snap-chill cabinet top, 12 to 28 furnace rolls and the push-and-pull head of transmission charging tray is equipped with in the bottom, the liquid nitrogen spraying system is equipped with in the furnace rolls bottom, the fire door lifting device connects the lifting fire door, the roller transmission mechanism drives upper right material bench roller road, is installed in open kinematic chain on the left feeding platform and pushes and pull out charging tray.Main points of the present utility model are its version and operation principle.Its operation principle and using method are: one, carbon potential braking control system principle is by means of N
2The pressure of gas, methyl alcohol (CH
3OH) by N
2Air-blowing nebulizes, N
2Gas and vaporific methyl alcohol are in charge of by 28 of heating clamber both sides and are evenly blowed in the stove, and methyl alcohol just can blow in the stove greater than 750 ℃ in furnace temperature.Be cracked into CO and H under the high temperature
2And residual O in the stove
2In conjunction with, generate CO
2And H
2O with not oxidation of preservative, by zirconia probe, measures O in the stove
2Gesture by single channel carbon potential control meter in the instrument room, is demarcated the interior carbon potential of coming out of the stove.Automatically control carbon potential in the stove by carbon potential control meter and the interlock of methyl alcohol flow multi-function electromagnetic valve,, make neither decarburization of furnace charge, also not carburizing to reach setting value; Its two, liquid N
2The spray cooling system principle ,-196 ℃ liquid N
2, in the snap-chill cabinet bottom, by tens special nozzles, the high temperature furnace charge that nebulizes and spray to 1250 ℃, heated N
2Gas by the cold circulating fan of furnace roof strong wind water gaging, blows to stove both sides by-pass water cooler again, the N that is cooled
2The liquid N that gas is accompanied again and constantly sprayed
2, blow to furnace charge once more, go round and begin again disposable the quench purpose of brightness heat treatment of soldering, gas of finishing of furnace charge after 20 minutes.It is as follows to push away the technological process of chain type controlled atmosphere soldering oven: blade is contained in the charging basket, lifts on the pallet on the material bench roller road, pushes snap-chill cabinet (clean room) automatically by mechanical driving device and push-pull mechanism, feeds N
2Gas purifies 10 minutes, and the clean room is hermetically sealed mechanism.Furnace charge purifies the back and pushes heating clamber rapidly by push-pull mechanism, the 1500kg furnace charge is heated to 1260 ℃ by 20 ℃, approximately need 40 minutes, behind the automatic heat preserving 20 minutes, automatically report to the police and come out of the stove, by after pushing away chain mechanism and drawing in the temperature that snap-chill cabinet (clean room) is cooled to rapidly come out of the stove, pull out outside the stove in 10 seconds, finished the purpose of the gentle brightness heat treatment of quenching of soldering simultaneously.When in snap-chill cabinet, cooling off, several big air quantity cool cycles fans of cooling of furnace bottom liquid nitrogen spraying and furnace roof start simultaneously automatically, the stove both sides have 12 groups of bypass coolers to lead to water quench, under liquid nitrogen spraying and the effect of water cooler dual-cooled, furnace charge is cooled to tapping temperature rapidly, and liquid nitrogen spraying stops automatically.Using method is: full stove can be established operator 1-2 people, and overall process is operated automatically by button, and process curve can be imported temperature control instrument and automatically perform, and all control data can be set in advance and automatically perform.
