Abstract
The invention relates to a portable high frequency heating puller which has a structure that an output end of a high frequency current heater is connected with a heating coil through a high frequency wire; the high frequency current heater has a structure that a rectifier is connected with a direct current filter; the direct current filter is connected with an inverter; the inverter is connected with an output circuit. According to the portable high frequency heating puller, by adopting the high-frequency eddy current principle, a heated bolt is partially heated fast by the high frequency magnetic flux generated by high frequency current around the heating coil, and is expanded and loosened; rust and paint are heated to realize calcification, and thus the disassembly is facilitated.
Description
Technical field
The present invention relates to a kind of power system detaching equipment, relate in particular to a kind of portable high frequency heating stripping attachment.
Background technology
In power system, dismounting used equipment is wasted time and energy, to dismantle old bolt as example, and the conventional blowtorch heating of the old bolt of existing dismounting, welding torch heating or cutting, the shortcoming such as the means such as disengaging device or electric tool cutting, exist speed slow, and labour intensity is large.And the method for loosening agent and oil lubrication need to be prepared in advance and effect is general.
Heating is compared with said method, and effect is better, but has naked light, and the heat time is long, makes around the article problem such as be heated.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, utilize electromagnetic induction principle, a kind of portable high frequency heating stripping attachment is provided,, solve the problem that used equipment is wasted time and energy of dismantling in prior art.
Technical scheme of the present invention is as follows:

Detailed description of the invention
embodiment
As shown in Figure 1, high frequency electric heater 1 input connects attaching plug 2, and high frequency electric heater 1 output connects heater coil 8 by high-frequency lead 6, between high frequency electric heater 1 and heater coil 8, is provided with switch 7; Described high frequency electric heater structure is that rectifier connects DC filter, DC filter connection inverter, inverter connection output circuit.
Described inverter is made up of voltage-type single-phase full bridge circuit.
Described output circuit is series resonant tank.
Described heater coil is the copper coil of closed circumference.
Described high frequency electric heater is provided with braces 5, relay indicating light 3 and the power supply indicator 4 born for staff.
As shown in Figure 2, alternating current is converted to direct current by rectifier to operation principle of the present invention, and direct current is by DC filter filtering, and inverter is exchanged for high-frequency ac direct current, and output circuit transfers to heater coil high frequency power, thus heating of metal workpiece.
DC filter is mainly made up of IGCT SCR, direct current reactance La and electrochemical capacitor Ca, and input voltage is power frequency 220V, and more than maximum direct voltage output can reach 450V, output direct current can be 100A.
Inversion part is exchanged for high-frequency ac direct current, formed by voltage-type single-phase full bridge circuit, use the SIT of 1kW level power consumption as the switching device of inverter bridge, while using with the SIT device built-up circuit of one-level power consumption, if when SIT starts to turn-off and produces surge voltage while exceeding the DC voltage in these circuit, diode conducting, and capacitor absorbs this surge energy, makes the SIT device safe operation in inverter bridge.
Output circuit part is that high frequency power is transferred on heated metal works, and the series resonant tank in this circuit has formed the each high frequency voltage producing more than several dry volts of voltage source type inverter capacitor CT and inductance L T two ends.Connecting heater coil Lc, huge high frequency electric high frequency magnetic flux that produces around heater coil Lc sharply generates heat metal bolts.
Work engineering of the present invention is, turns on the power switch after connecting working power, and power lights lights, and bears operation.After pressing operating switch 1-2min after heater coil is enclosed within on wish heating bolt, bolt is heated expansion corrosion or paints efflorescence and can easily dismantle.
Power output of the present invention: 2-3kW, output frequency: 30-40kHz, maximum operation (service) temperature: 500-800 DEG C, heavy 5kg.
The above is specific embodiments of the invention and the know-why used, and any equivalent transformation based on technical solution of the present invention basis, within all belonging to protection scope of the present invention.
