Abstract
The utility model discloses a two-circuit medium-frequency induction heating furnace. The heating furnace comprises a power cylinder, a guide plate, a front medium-frequency furnace and a rear medium-frequency furnace which are fixed on an upper plane of a base from the left to the right successively. An unloading support is mounted at the right end of the base and disposed below a hearth outlet of the rear medium-frequency furnace. A piston rod of the power cylinder faces a hearth inlet of the front medium-frequency furnace. The front medium-frequency furnace and the rear medium-frequency furnace are provided with an induction circuit respectively, the induction circuits are different in power, and the two hearths which are matched and identical in size are coaxial. According to the heating furnace, a work-piece pushed by the power cylinder moves straightly along the guide plate to enter the cavity through the hearth inlet of the front medium-frequency furnace, the front medium-frequency furnace power occupies 35% to 45% of rated heating power and is mainly used for preheating the work-piece, and the rear medium-frequency furnace power occupies 55% to 65% of rated heating power and is mainly used for heating the work-piece. By means of the heating furnace, the work-piece can be heated thoroughly, the internal and external temperatures of the work-piece are consistent, forging forming is facilitated, and a forging die can be protected against being damaged without reason.
Description
Technical field
The utility model relates to a kind of industrial stove and accessory, and specifically, the utility model relates to a kind of double loop Medium Frequency Induction Heating Furnace.
Background technology
Medium Frequency Induction Heating Furnace belongs to conventional industrial stove and accessory, and it has the features such as simple in structure, volume is little, quick heating, the thermal efficiency is high, blowdown is few, is particularly suitable for machine components and heats.The induction coil that the Medium Frequency Induction Heating Furnace of prior art is equipped with is single loop, under rated power condition, through time enough eddy-current heating, can accomplish homogeneous heating workpiece, can meet thermal forging technology requirement completely.In actual production, in hot forging production line, forging beat is than the fast several times of heating productive temp, and heating process is the deciding factor that affects production efficiency thus.Although shorten the heat time, can enhance productivity, easily cause not heat penetration of workpiece, surface heating temperature reaches setting value, and central part heating-up temperature is lower than setting value, and this kind of situation is more aobvious outstanding in the slightly large workpiece of diameter.The workpiece of heat penetration forging difficulty is not large, and forging quality is poor, and forging die is also produced to harmful effect.
Utility model content
The utility model is long mainly for the single loop Medium Frequency Induction Heating Furnace heat time, with the inharmonic problem of forging beat, a kind of employing heat stepwise is proposed, reasonable distribution heat energy, guarantee the double loop Medium Frequency Induction Heating Furnace of workpiece heat penetration, this furnace thermal efficiency is high, and heating quality is stable, is conducive to efficiently implement postorder forging.
The utility model is achieved through the following technical solutions technical goal.
Double loop Medium Frequency Induction Heating Furnace, it comprises on pedestal plane hard-wired power cylinder, stock guide, front intermediate frequency furnace and rear intermediate frequency furnace successively from left to right, discharging holder is arranged on pedestal right side and is positioned under the furnace outlet of rear intermediate frequency furnace.The piston rod of described power cylinder is the burner hearth import of intermediate frequency furnace forward-facing.Its improvements are: described front intermediate frequency furnace and rear intermediate frequency furnace are furnished with power loop inductance not etc. separately, two join and measure-alike burner hearth coaxial.
As further improvement project, front intermediate frequency furnace power accounts for specified heating power 35%～45%, and rear intermediate frequency furnace (5) power accounts for specified heating power 55%～65%.
The utility model compared with prior art, has following good effect:
1, two intermediate frequency furnace series arrangement are simple, make easily;
2, the intermediate frequency furnace power of two series windings of reasonable distribution, through the workpiece of preheating after easy heat penetration in heating process, be conducive to improve forging quality.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation, and the power cylinder in figure is in treating work state.
Fig. 2 is the top view of Fig. 1, and the piston rod of figure medium power cylinder extends in the import of front intermediate frequency furnace burner hearth, also from one of outlet release, has heated material and come out of the stove when packing a material into from import.
The specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments, the utility model is described in further detail.
Double loop Medium Frequency Induction Heating Furnace shown in Fig. 1, it comprises on pedestal 1 plane hard-wired power cylinder 2, stock guide 3, front intermediate frequency furnace 4 and rear intermediate frequency furnace 5 successively from left to right, discharging holder 6 is arranged on pedestal 1 right side and is positioned under the furnace outlet 5.1 of rear intermediate frequency furnace 5, on conveyer belt when the workpiece 7 of heating is come out of the stove under discharging holder 6 drops down onto, workpiece 7 is sent to follow-up forging station for processing and forming.The piston rod of described power cylinder 2 is the burner hearth import 4.1 of intermediate frequency furnace 4 forward-facing, improvement of the present utility model is to form a heating furnace by two intermediate frequency furnaces, front intermediate frequency furnace 4 and rear intermediate frequency furnace 5 are furnished with power loop inductance not etc. separately, two join and measure-alike burner hearth coaxial.For make workpiece 7 in intermediate frequency furnace burner hearth, obtain efficiently, evenly, reliably heating, the intermediate frequency furnace power of two series windings of reasonable distribution.Before in the present embodiment, intermediate frequency furnace 4 power account for specified heating power 40%, and rear intermediate frequency furnace 5 power account for specified heating power 60%.The object of distributing intermediate frequency furnace power, be allow workpiece 7 in burner hearth first through preheating, remake heating, through the workpiece 7 of preheating after easy heat penetration in heating process, after heating, workpiece 7 internal and external temperatures are identical.By the workpiece of technological requirement heat penetration 7, be conducive to forging forming, also protect forging die used not damaged without reason simultaneously.
The power division of front intermediate frequency furnace 4 and rear intermediate frequency furnace in the utility model, Main Basis workpiece 7 material used and moulding complexity, as long as front intermediate frequency furnace 4 power account for specified heating power 35%～45%, rear intermediate frequency furnace (5) power accounts for specified heating power 55%～65% all can obtain the effect that meets use.
The preferred hydraulic jack of power cylinder 2 of applying in the utility model, also can select pneumatic cylinder, can realize promoting the burner hearth import 4.1 that workpiece 7 keeps straight on premenstrual intermediate frequency furnace 4 along stock guide 3 and entering inner chamber.
