Abstract
The utility model discloses an induction coil heater, comprising a coil formed by continuously bending a conductive material. The two ends of the coil are equipped with electrodes. The induction coil heater is characterized in that the coil comprises two parallel end faces and two connecting parts for connecting the end faces. By using a coil having a half-sectional structure to substitute an original mobile scanning type single coil, the induction coil heater of the utility model guarantees the heat treatment effect of a depth layer effectively, does not need to replace the coil, enables the heating time to be shortened, at the same time, guarantees that the temperature of each part of a workpiece is uniform, and enables the cracking caused by the inner and outer stresses to be reduced. The induction coil heater of the utility model has the advantages that the structure is simple, the efficiency is high, the processing quality is good, etc.
Description
Technical field
The utility model relates to a kind of induction coil heater.
Background technology
The induction coil heater is a kind of inductance coil, and it can produce alternating magnetic field by alternating current, thereby produces high temperature at workpiece, with realization workpiece is heat-treated.The induction coil heater is the critical component of realizing all kinds of induction heating technologies, and its performance is directly connected to the good of heating process.At present, generally heat by the mode of unicoil by motion scan when heat-treating for the workpiece of cylindricality, although its loop construction is simple, but complicated integral structure, and heating time is long, depth layer (thermal treatment zone and not between the transition region between the thermal treatment zone) can not be guaranteed heating time, and transition is inhomogeneous, easily fracture.When the workpiece that step is arranged is heat-treated, also need the diameter according to the workpiece heating part, the transposing coil seriously reduces production efficiency.
Summary of the invention
The utility model provides a kind of solution of the above problems, and a kind of induction coil heater simple in structure, efficient, high-quality is provided.
The technical solution of the utility model provides a kind of induction coil heater, it comprises the coil of being made by an electric conducting material, described coil two ends are provided with electrode, it is characterized in that: described coil comprise two mutually parallel end face with are connected a connecting portion that connects two described end faces.
Preferably, described connecting portion cooperates with outer surface of workpiece shape to be processed.
Preferably, two described end faces are semicircular arc.
Preferably, two described end faces are circle.
Induction coil heater of the present utility model replaces the unicoil of original motion scan formula by the coil that partly cuts open structure, it has effectively guaranteed the thermal effectiveness of depth layer, and do not need more emat coil, shortened heating time, temperature is even everywhere simultaneously also to have guaranteed whole workpiece, has reduced the cracking that interior external carbuncle causes.The advantages such as induction coil heater of the present utility model has simple in structure, and efficient is high, crudy is good.
Description of drawings
Fig. 1 is the structural representation of induction coil heater the first embodiment of the present utility model;
Fig. 2 is the structural representation of induction coil heater the second embodiment of the present utility model.
Embodiment
The below is described in further detail embodiment of the present utility model.
As depicted in figs. 1 and 2, a kind of induction coil 10 heaters of the present utility model are coils 10 of being made by an electric conducting material, and this electric conducting material adopts material commonly used at present, such as copper, red copper etc.Coil 10 two ends are provided with electrode 12, are used for connecting AC power.Coil 10 comprise two mutually parallel end face 14 with are connected a connecting portion 16 that connects both ends of the surface 14.Connecting portion 16 cooperates with workpiece (not shown) outer surface shape to be processed, and namely the contour structures with workpiece to be processed is identical, thereby keeps connecting portion 16 all identical to the distance on workpiece each several part surface, thereby so that the workpiece each several part all obtains identical heating effect.Both ends of the surface 14 can be semicircular arcs as shown in Figure 1, also can be circles as shown in Figure 2.
A kind of induction coil 10 heaters of the present utility model are placed on workpiece to be heated between coil 10 both ends of the surface 14 in use, keep certain spacing, and rotational workpieces at the uniform velocity.So that the workpiece each several part, comprise depth layer between coil 10 simultaneously and thermally equivalent, avoided more emat coil 10, improved its operating efficiency, also improved the heating effect of depth layer.And do not need further to have saved cost with the action component that drives unicoil 10 and come flyback retrace.
Above embodiment only is the utility model a kind of execution mode wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
