Abstract
The utility model discloses an isothermal quenching device. The isothermal quenching device comprises a salt bath tank, wherein an electric heater and a water circulating coil pipe are arranged in the salt bath tank; a support frame is arranged on the salt bath tank; a speed reducer is arranged on the support frame; the input end of the speed reducer is connected with the output end of a motor; the output end of the speed reducer is connected with a rotating shaft; an impeller is arranged on the rotating shaft. The problems that the temperature of the position where a workpiece enters the salt bath tank is high, the temperature of the other end is low, and the temperature fluctuation is great are solved; the isothermal quenching device has the characteristics of consistent salt bath temperature and low temperature fluctuation; the general temperature change can be controlled between 5 and 10 DEG C; the product quality is greatly improved.
Description
Technical field
The utility model relates to a kind of heat treatment device, is specifically related to a kind of isothermal quenching device.
Background technology
The instrument complex-shaped, dimension precision requirement is higher and important machine parts, as pick, mould, cutter, gear etc., adopt means of isothermal quenching, mostly to strengthen intensity, hardness, toughness, wear resistance and the plasticity of steel.At present, pick is in isothermal quenching process, due to workpiece, to enter salt bath place temperature higher, and lower in the other end temperature of salt bath, forms the case hardening salt bath temperature difference large, cause workpiece quenching hardness unstable, for controlling salt bath temperature, raise, adopted again and let cool water-cooling method, this method shortcoming is lowered the temperature soon, heats up slow exactly, the temperature range of wayward quenching, causes pick hardness unstable and affect quality product.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of salt temperature and reaches unanimity, the isothermal quenching device that temperature fluctuation is little.
For solving the problems of the technologies described above, isothermal quenching device of the present utility model comprises salt bath, in salt bath, be provided with electric heater, be also provided with water cycle coil pipe, salt bath is provided with bracing frame, speed reduction unit is installed on bracing frame, the input terminus of speed reduction unit is connected with the output terminal of motor, and the output terminal of speed reduction unit is connected with rotating shaft, and impeller is installed in rotating shaft.
A handles is respectively established in the both sides of described bracing frame.
Because technique scheme is provided with water cycle coil pipe in salt bath, cooling down in good time when salt bath temperature raises, the agitator that employing is comprised of bracing frame, speed reduction unit, motor, rotating shaft, impeller, can solving workpiece, to enter salt bath place temperature higher, and in the lower problem of the other end temperature of salt bath, therefore, the combination of agitator and water circulation system, easily control the temperature range of quenching, salt temperature reaches unanimity, temperature fluctuation is little, and general temperature variation can be controlled between 5-10 degree Celsius, has greatly improved quality product.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model isothermal quenching device.
Embodiment
As seen from Figure 1, isothermal quenching device of the present utility model comprises salt bath 1, is provided with electric heater 2, water cycle coil pipe 3 in salt bath 1, and the feed-water end of water cycle coil pipe 3 is installed magnetic valve 10, and magnetic valve 10 is controlled and opened and close by thermostat.In salt bath 1, be also provided with agitator, this agitator comprises bracing frame 4, bracing frame 4 is placed on salt bath 1, speed reduction unit 5 is installed on bracing frame 4, and the input terminus of speed reduction unit 5 is connected with the output terminal of motor 6, and the output terminal of speed reduction unit 5 is connected with rotating shaft 7, impeller 8 is installed in rotating shaft 7, according to the volume of salt bath 1, in rotating shaft 7, a plurality of impellers can be installed, to improve stirring efficiency.For ease of movable supporting frame 4, in the both sides of bracing frame 4, respectively establish a handles 9.
While using the utility model isothermal quenching device, first, by the salt bath of 1 li of electric heater 2 heating salt bath, make it reach design temperature, the pick of high temperature forging (or other workpiece) is sent constantly in salt bath 1 and quenched, starter motor 6, impeller 8 stirs salt bath, and salt temperature is reached unanimity.When salt temperature raises, fluctuate when larger, thermostat is opened magnetic valve 10, and cold water enters the freezing salt bath of water cycle coil pipe 3, when salt temperature is reduced to design temperature, stops water cycle.The pick hardness of processing through the utility model isothermal quenching device is stable, and quality product improves.
Claims (2)
