Description
Technical field
The utility model belongs to metal processing and heat treatment equipment technical field, is specifically related to a kind of constant temperature quenching device.
Background technology
What at present, domestic mechanical processing industry adopted usually to the quenching heat treatment of metallic substance is the mode of shrend, oil quenching and Special quenching liquid.Wherein water is as a kind of modal quenchant is inexpensive owing to it, cost is low, pollution-free being widely adopted, the chemical stability of water is very high, but in the heat treatment process when water temperature is elevated to 80 ℃ from 40 ℃, about 1/8 the when cooling rate of workpiece under 600 ℃ can be reduced to water temperature and be 40 ℃.Cooling power at senior middle school's warm area water is not strong, but cooling rate is very high again at cold zone, because water is large in low thermophase speed of cooling, even workpiece can harden, its thermal stresses and structural stress are also very high, often can cause the workpiece problem of Cracking.This cooling characteristic of water be difficult to be grasped aborning, and at present, the problems such as a difficult problem that shrend easily splits and the bad control of characteristic can appear in domestic mechanical processing industry usually to the quenching heat treatment of metallic substance shrend, bring a series of difficult problems to actual production.
The utility model content
Technical problem to be solved in the utility model is a difficult problem of easily splitting for shrend in the prior art and a kind of simple in structure, easy to operate, production cost is low, the quality of workpiece high, production efficiency is high constant temperature quenching device is provided.
Adopt following technical scheme for solving technical problem of the present utility model:
A kind of constant temperature quenching device, comprise device case and fluid box, establish fluid box in the described device case, be provided with perlite between described device case and the fluid box, the bottom of described fluid box is provided with dividing plate, and described dividing plate is provided with the liquid communication hole, and described dividing plate top is provided with work support, described dividing plate below is provided with temperature measurer and well heater, and described temperature measurer is connected with temperature control unit with well heater.
The temperature range of described temperature control unit control water extract is 60 ℃-80 ℃.
Described dividing plate is connected with adjusting screw with work support.
Described fluid box top is provided with the liquid inlet, and described fluid box bottom is provided with liquid exit.
Gap between device case of the present utility model and the fluid box adopts perlite to fill, liquid in the case has been played effective insulation effect, workpiece Frequency Induction Heating to reasonable temperature is put into the water extract of fluid box, the temperature of strictly controlling water extract by temperature control unit is 60 ℃-80 ℃ and cooling time, has guaranteed quality and the quenching requirement of workpiece.The utility model has adopted hardening liquid to flow and the thermostatic control mode, a kind of simple in structure take water as quenchant, easy to operate, inexpensive pollution-free, production cost is low, and workpiece quality is high, quenching device, realize batch production, improved production efficiency, solved the difficult problem that shrend is easily split in the actual production.
