Abstract
The invention discloses a forging waste heat quenching device, which is mainly characterized in that the device is a waste heat quenching device after steel elements are forged. The forging waste heat quenching device mainly consists of a variable-frequency transmission chain, a variable-frequency stirring water pump, a circulation water pump, a cooling device and a quenching water tank. The rest heat after the steel elements are forged is directly used for quenching, the variable-frequency speed regulating transmission chain changes the transmission chain lifting speed through changing the rotating speed of a motor, the quenching water outlet temperature is ensured, the martensite conversation speed is controlled, and the occurrence of quenching cracks is effectively prevented. The invention can meet the cooling speed requirement of the quenching of various steel types through regulating the quenching intensity of quenching media by changing the rotating speed of the variable-frequency stirring water pump. The circulation water pump and the cooling device effectively ensure the use temperature of the quenching media. When the waste heat quenching device of the invention is used for carrying out waste heat quenching, the stable product quality can be ensured, and the production efficiency can be improved.
Description
Technical field
The present invention relates to waste heat quenching device, be specifically related to a kind of remnant forging thermal quenching device.
Background technology
Advocate energetically in countries in the world at present, under the policy that reduces discharging, lowers consumption, domestic many scholars, enterprise take measures from every side, and forged hardening is one of important measures wherein; Forged hardening equals to have lacked the primary quenching heating; Forge the back Heat Treatment and can save the energy and man-hour in a large number, raise labour productivity, thermomechanical treatment also can make forging obtain good comprehensive mechanical properties in addition.Countries in the world are all adopted in a large number and are forged the back Heat Treatment for this reason; Remnant forging thermal quenching is that the hot extrusion molding of forging and thermal treatment are closely combined, and by certain beat continuous production, forging must quench after forging immediately; Waste heat quenching device then is the key that effectively guarantees the immediate quenching quality.The domestic device that has the employing crank to connect pendulum basket formula, carry out immediate quenching, this device is to be made of crankshaft connecting rod system and quenching supplementary unit two parts, this crankshaft connecting rod system mainly is made of quenching tank, basket frame, bent axle, connecting rod step-down gear etc., its shortcoming is that the quench cooled time difference of initial workpiece and last part product is excessive, can not effectively guarantee the homogeneity of workpiece quenching leaving water temperature(LWT), cause the hardness of cracking and minority workpiece overproof.
Summary of the invention
At the problems referred to above, the objective of the invention is to design a kind of waste heat quenching device, this device not only can dwindle the time difference of the quench cooled of initial workpiece and last part product, can effectively guarantee the homogeneity of workpiece quenching leaving water temperature(LWT), guarantee constant product quality, also improved production efficiency.
For achieving the above object, the technical scheme that the present invention takes is that this device is a steel part forged hardening device, mainly is made up of frequency conversion conveyer chain, frequency conversion stirring pump, water circulating pump, refrigerating unit and quenching bath; Wherein the frequency conversion conveyer chain is made up of variable-frequency power sources, electric motor, step-down gear and conveyer chain, is arranged in quenching bath, is arranged in the quenching bath with stent support by certain angle; The frequency conversion stirring pump can be installed in quenching pool side optional position, and water-in is positioned at the quenching bath middle and lower part, and water outlet is positioned at the conveyer chain low side, jet water course and basic keeping parallelism above the conveyer chain; Link to each other with quenching bath and to be disposed with counterbalance cell and the pond that connects material; The water circulating pump water-in is positioned at the counterbalance cell middle and lower part, and water outlet is positioned near the conveyer chain low side, and water (flow) direction vertically upward.
Described refrigerating unit is with cooling tower or interchanger.
Described frequency conversion conveyer chain is obliquely installed in quenching bath, and the angle of its inclination is: 10 °～60 °.
Quenching bath is made with Steel Concrete or steel plate welding.
Utilize the surplus heat after steel part forges directly to quench; The speed control by frequency variation conveyer chain changes the conveyer chain pulling speed by changing motor speed, guarantees the quenching leaving water temperature(LWT), controls martensitic velocity of transformation, effectively prevents the appearance of quenching crack; Adjust the quenching intensity of quenchant by the rotating speed that changes the frequency conversion stirring pump, can satisfy the speed of cooling requirement that many steel grades quench; Water circulating pump and refrigerating unit have effectively guaranteed the use temperature of quenchant.
Utilize waste heat quenching device of the present invention to carry out immediate quenching, not only can dwindle the time difference of the quench cooled of initial workpiece and last part product, can effectively guarantee the homogeneity of workpiece quenching leaving water temperature(LWT), guarantee constant product quality, also improved production efficiency.
