Description
Technical field
The invention belongs to electric heating field, more particularly to a kind of stalk flange heating device.
Background technology
In Low Pressure Die Casting of Aluminum Wheel Hub production process, dry wind is squeezed into molten aluminum holding furnace, under the effect of the pressure
Molten aluminum flows through coagulation forming in stalk to mold cavity through pipette in holding furnace.Although through being overpressurized, protecting when mould pressurizing
The pressure stage, but when to the pressure release stage, due to the reduction of air pressure, molten aluminum is under gravity from pipette to a liter liquid
Pipe is back in holding furnace.Stalk lower end is higher due to being in temperature in holding furnace, and pipette upper end is in contact temperature with mold
Degree it is higher, but in stalk with pipette intersection, that is, stalk flange section due to being exposed to for a long time in outside air and without outer
Boundary's heating device is low so as to cause stalk flange temperature.Cause molten aluminum in pressure release rank since the temperature of stalk flange is low
Part molten aluminum, which is solidified on stalk and the inner wall of pipette, when section is back to by gravity in holding furnace causes stalk flange
Neighbouring a large amount of slagging.
Due in order to increase the filtering of molten aluminum, reducing aluminium slag and entering mold cavity pipette used at present with filter
Piece, and the position of pipette filter disc is in stalk flange.A large amount of slagging can cause pipette filter disc to block, and cause molten aluminum
Flowing velocity is uneven so that number the defects of stomata, slag inclusion, misrun, current mark in the wheel hub produced in cavity filling process
Amount greatly increases, and working as bits mostly can even make running channel blocks cause stifled riser, run the safety accidents such as aluminium.
Invention content
For deficiency existing for above-mentioned existing issue, the present invention provides a kind of stalk flange heating device, solves liter
The problem of liquid pipe flange temperature is low, easy slagging.The configuration of the present invention is simple, it is easy to use, it securely and reliably, can using the present apparatus
Stalk flange is heated to assigned temperature, and operating temperature can be adjusted, to ensure that aluminum liquid filling type pours in the process
Road it is unobstructed.
A kind of stalk flange heating device, it is characterised in that：The heating device include high-temperature insulation shell, resistance wire,
Thermocouple wire, through hole, annular groove, the high-temperature insulation shell are loop configuration, and the resistance wire crouches in annular groove, resistance wire
Both ends are stretched out inside through hole, and the thermocouple wire enters outside through hole.
Further, high-temperature insulation shell is made using ceramic fibre material.
Further, the inner ring side of high-temperature insulation shell is provided with two ring annular grooves.
Further, the inner ring internal diameter of high-temperature insulation shell is greater than stalk flange outer diameter.
When operation, need by resistance wire expose to high-temperature insulation shell parts put on bowl-type porcelain bead to insulate, high temperature resistant,
High-temperature insulation shell is placed on outside stalk flange, the other end of resistance wire and thermocouple wire is connected with temperature control module, after energization first
It is heated with low temperature, thermocouple line position is adjusted after temperature stabilization, so that thermocouple wire can accurately measure stalk flange
The temperature at place.
It is the configuration of the present invention is simple, easy to operate, stalk flange slagging serious problems can be substantially reduced and ensure molten aluminum
Flowing velocity is uniform in cavity filling process, and stomata, slag inclusion, misrun, current mark etc. are generated in casting process to reduce wheel hub
The quantity of defect is eliminated and causes the safety accidents such as raw stifled riser, race aluminium since running channel blocks.
Description of the drawings
Fig. 1 is the vertical view of the embodiment of the present invention.
Fig. 2 is the front view of the embodiment of the present invention.
Digital representation is as follows in figure：1. high-temperature insulation shell, 2. resistance wires, 3. thermocouple wires, 4. through holes, 5. annular grooves,
4. through hole, 5. annular grooves.
Specific implementation mode
With reference to embodiment and attached drawing, invention is further described in detail：
As shown in Figure 1, 2, the embodiment of the present invention includes a kind of stalk flange heating devices, including 1. high-temperature insulation shells, 2.
Resistance wire, 3. thermocouple wires, 4. through holes, 5. annular grooves, 4. through holes, 5. annular grooves composition.The high-temperature insulation shell 1 it is interior
Ring side is provided with two ring annular grooves 5, and outer shroud side is provided with three through holes 4, and through hole 4 can lead to medial surface by lateral surface.
The high-temperature insulation shell 1 is loop configuration, and the thermocouple wire 3 enters from 4 outside of through hole, and the resistance wire 2 crouches in annular
In slot 5,2 both ends of resistance wire are stretched out from 4 inside of through hole.The high-temperature insulation shell 1 is made using ceramic fibre.
When being operated using this patent, need by resistance wire 2 expose to 1 part of high-temperature insulation shell put on bowl-type porcelain bead so as to
Insulation, high temperature resistant, are entangled stalk flange with high-temperature insulation shell 1, the other end and the temperature control mould of resistance wire 2 and thermocouple wire 3
Block is connected, and is first heated with low temperature after energization, 3 position of adjustment thermocouple wire after temperature stabilization, so that thermocouple wire 3 can be accurate
Measure the temperature of stalk flange.Resistance wire 2 generates heat after being powered, and stalk method is conducted heat to by heat radiation
Lan Shang, to improve stalk flange temperature.
The experiment proved that after being heated to stalk flange using this patent, using the pipette filter disc of a cycle,
Stalk flange slagging significantly reduces, and molten aluminum rising running channel is more unobstructed, causes because running channel is unsmooth in wheel hub casting process
Stomata, slag inclusion, misrun, current mark the defects of quantity significantly reduce, while eliminating because of running channel blocks stifled emitting of occurring
Mouth runs the safety accidents such as aluminium.
