The utility model discloses upper half-turn rotary opening axis classes to quench Medium frequency induction circle, including upper semi-circle Medium frequency induction circle and lower half circle Medium frequency induction circle, it is characterised in that: be divided into chilled water circuit chamber by spacing board in the lower half circle Medium frequency induction circle and upper semi-circle Medium frequency induction circle；Upper semi-circle Medium frequency induction circle and its rotation histogram pipeline section are rotated up and down by cylinder realization, to realize folding of the upper semi-circle Medium frequency induction circle with respect to lower half circle Medium frequency induction circle.The utility model can not only be such that induction coil opens and closes, and open and close it is more convenient, quenching shaft forgings can very easily be placed under horizontal direction or horizontal direction on take out, more time saving and energy saving, safe operation；Since the contact of each connecting portion is good, so not influencing heating quality；There is independent chilled(cooling) water return (CWR) in the semicircle induction coil of upside and the semicircle induction coil of downside, and keep hydraulic pressure consistent, so having good cooling effect, keeps heating consistent.It can be widely used for shaft forgings quenching process.
Description
Technical field
It is specifically a kind of convenient for heating shaft forgings horizontal direction the utility model relates to a kind of improvement of Medium frequency induction circle
It is proposed in Medium frequency induction circle in lower merging or horizontal direction, and on more time saving, labour-saving in the quenching of half-turn rotary opening axis class
Frequency induction coil is suitable for Surface of Rod Bar quenching process.
Background technique
It is well known that using intermediate frequency furnace to metal works quench or it is diathermanous, have following clear advantage, 1, heating temperature
Height, it is contactless；2, heating efficiency is high, energy conservation；3, heating speed is fast, uniformly, it is few to be heated workpiece surface oxidation；4, temperature is easy
Control, stable product quality；5, pollution-free.Therefore, intermediate frequency furnace induction coil heating is widely used.Intermediate frequency heating is to pass through
Medium frequency induction snare is passed through the realization of frequency conversion electric current on heating workpiece, since the shape of workpiece is different, so in used
The shape of frequency induction coil is also different.Bar is quenched or diathermanous, such as shaft-like workpiece, required Medium frequency induction circle is circle,
This circle Medium frequency induction circle, is that annular shape will be curved in the middle part of a red copper square tube, and circular diameter, which is greater than, is quenched axis
The diameter of part is quenched surface and the annular shape induction coil inner wall of shaft member when insertion needs quenching or diathermanous shaft-like workpiece
With a certain distance, be it is contactless, can be along the axial movement for being quenched shaft member, the straight pipe at the both ends of red copper square tube is simultaneously
It is passed through frequency conversion electric current, and accesses water inlet pipe at one end, the other end accesses outlet pipe, makes to access circulating cooling in circular induction coil
Water.In use, need will the shaft forgings of working process be inserted into circular induction coil, then will working process shaft forgings two
End passes through top fixation.Obviously, the deficiency of this circular induction coil is: when being inserted into the shaft forgings to be heated, taking
When it is laborious, it is inconvenient, and be also easy to collision Medium frequency induction circle, cause Medium frequency induction circle damage.By retrieving it is found that being
Overcome the above the deficiencies in the prior art, Chinese patent CN207479833U discloses a kind of " soot blower gun barrel Medium frequency induction
Circle ", including upper semi-circle induction coil, lower half circle induction coil, upper backboard, lower backboard, upper cylinder and lower cylinder, upper cylinder and lower cylinder
It is fixed with box rack, upper semi-circle induction coil is fixed in upper backboard, and the piston rod of upper backboard and upper cylinder is fixed, upper semi-circle
The semicircle mouth down of induction coil can make upper semi-circle induction coil be lifted up or transfer by the flexible of upper cylinder；Lower half circle induction
Circle is fixed in lower backboard, and the piston rod of lower backboard and lower cylinder is fixed, and the semicircular opening of lower half circle induction coil is upward, passes through lower gas
Stretching for cylinder, can make lower half circle induction coil pull downward on or push up；It is realized above and below by being acted while upper and lower cylinder
The opposite folding of semicircle induction coil.The design amplifies mouth by the opposed open of upper and lower semicircle induction coil, so that shaft forgings
It is become easy when insertion, it is not easy to damaged in collision induction coil, but still be that shaft forgings are inserted into induction coil, or are put not as good as level
It is convenient in induction coil to enter, and is limited by box rack, so, the design cannot make shaft forgings realize that water level is lowered into
In induction coil, and the design does not solve the problems, such as that water route is cooling；In addition, the design needs two cylinders, cause structure multiple
It is miscellaneous, inconvenience operation.
In addition, also have the report of upper half circle induction coil and lower semi-circular induction coil make-up in the reference book having in the past,
Upper half circle induction coil is flipped up, and lower semi-circular induction coil downwardly turns over, and is formed to front open mouth, in use, will quenching or saturating
In the shaft-like workpiece level push-in induction coil of heat, this design, since upper half circle induction coil and lower semi-circular induction coil all need
It overturns, causes that structure is complicated, in addition, also without solving the problems, such as that water route is cooling；Level push-in heating workpiece need to be with biggish
Lifting force, it is also more bothersome.
Summary of the invention
