Background technology
At present, what the quenching heat treatment of domestic mechanical processing industry to metallic substance adopted usually is salt bath heating, box-type furnace heating and induction heating mode.Wherein induction heating as a kind of novel heating means because it is inexpensive, cost is low, easy to operate and be widely adopted.But because induction heating mode only adopts simple beam as support usually, the transmission speed of artificial grasp workpiece, individual difference is larger, only rely on naked eyes and experience to go to control to the acid extraction of workpiece, be difficult to ensure the penetration of heat homogeneity of Heating temperature and the unity of quenching temperature requirement.The heating quenching of workpiece is very high to the requirement of temperature, the too high meeting of temperature makes its thermal distortion larger, also certain influence is had to its interior tissue, temperature is too low, affect workpiece quenching hardness and quality product, too high and the too low quenching quality all not ensureing product of temperature, therefore brings an a series of difficult problem to actual production.
Summary of the invention
Technical problem to be solved by this invention provides for problems such as the difficult problem that temperature in prior art is wayward and penetration of heat is uneven and other heating quenching mode production cost are high, not easy to operate the thermal treatment automatic heating device that a kind of structure is simple, easy to operate, production cost is low, the quality of workpiece is high, production efficiency is high.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of thermal treatment automatic heating device, comprises transmission frame and quenching tank, and transmission frame is provided with motor, speed reduction unit and adjustablely takes turns, and adjustable wheel is connected with motion-work wheel, is provided with induction heating circle above transmission frame, is provided with temperature controller outside induction heating circle.
Described speed reduction unit is connected with at least one group of adjustable wheel, often organize adjustable take turns respectively with motion-work wheel, often organize motion-work wheel be connected with follow-up pulley.
The outer rim of described motion-work wheel and follow-up pulley is positioned at same plane.
Described adjustable wheel forms multistep cone pulley by the fifth wheel of various outer diameter.
Hardening liquid and agitator is provided with in described quenching tank.
The helically line arrangement of described induction heating circle.
The gap of described induction heating circle inwall and workpiece external diameter is 1mm-3mm.
Described temperature controller regulates induction heating circle temperature, and temperature regulating range is 600 DEG C-1000 DEG C.
Described adjustable wheel is connected with agitator.
The present invention realizes primary speed-down by regulating the transmission velocity ratio of step-down gear, adjustable wheel forms multistep cone pulley by the fifth wheel of various outer diameter, mounting various outer diameter fifth wheel realizes the object of doublereduction, drive sprocket drives driven running roller in chain mode, substantially reduce beating when belt pulley operates, workpiece transfer operates steadily.The gap of 1mm-3mm is left between induction heating circle and workpiece, ensure that the ideal space of inducedmagnetic field and the homogeneity of penetration of heat and the requirement to quenching temperature, regulate and adjustablely take turns the agitator simultaneously driven in quenching tank, hardening liquid in oil groove is played to the object of cooling and homogeneous temperature in time, thus ensure that quality and the quenching requirement of workpiece, the temperature controller of inductor block periphery, when temperature reach design temperature be inductor block by auto-breaking, stop heating.The invention provides a kind of structure simple, easy to operate, control the method for workpiece travelling speed to control the Heating temperature of workpiece with mechanical transmission, double reduction is taken turns with adjustment is adjustable by speed reduction unit, workpiece transfer speed can be regulated at any time, strictly control workpiece heat temperature by temperature controller, ensure that penetration of heat homogeneity and the quenching temperature requirement of workpiece.The present invention passes through stability and the homogeneity of the Heating temperature changing workpiece transfer speed control workpiece when thermal treatment, solve workpiece in actual production not easily to heat, heat operation problem that is uneven, the bad control of heat characteristic, be particularly suitable for the heat treatment process of rod-shaped workpiece.Realize the batch production of workpiece, substantially increase production efficiency.
