The present invention, as once sensing the overall structure of heating, first considers the trend performance that electric current is taken a shortcut,
Under the conditions of the size of this external copper tube, shape, the selection of thickness have taken into full account that power work frequency is relatively low
Anti-vibration resistance, have the cooling water of sufficiently flowing, in case larger current causes the fusing in copper tube work.
U-shaped stalloy magnetic conductor effect is to assemble magnetic induction line, when electric current is by copper tube, due to heart portion magnetic
Flux density is big, and self-induced e.m.f is also big, and electric current is driven to the open side that induction reactance is less, improves corresponding site and adds
Hot temperature.
Support the groove portion vertical copper tube of heating 3 and support groove portion heating arcuation spiral copper tube 5 to support
Raceway axle portion 14 electromagnetic induction heating, vertical bar type, U-shaped second stalloy magnetic conductor 4 are distributed on support raceway
Gathering magnetic induction line on vertical copper tube 3 is heated in portion, and electric current is driven onto on axial plane the raising efficiency of heating surface.
Protruding end face supports raceway shaft shoulder root circle with supporting groove portion transition arc heating copper tube 7 to first
Arc 17 carries out electromagnetic induction heating.3rd stalloy magnetic conductor 6 is arranged on protruding end face and supports groove portion mistake
Cross, on circular arc heating copper tube 7, root circular arc is assembled magnetic induction line, improve the heating of circular arc root toward temperature.
Cooling water enters from cooling water inlet 12, then flows out from coolant outlet 8, under duty
Copper tube is lowered the temperature.
Insulation board 11 is then that the first electrode 10 and the second electrode 9 are separated insulation.
The operation principle of the present invention is described below.
According to smithcraft quenching technology requirement, the first electrode 10 and the second electrode 9 are incorporated to power supply, electricity
Stream sequentially flows through the coil of each copper tube composition, when being connected with alternating current in coil, in the inside of coil
And just produce an alternating magnetic field about, it is placed in the workpiece of coil inside just by the magnetic line of force institute of alternating magnetic field
Cutting, then will have induction electromotive force to produce in support raceway axle portion, and produce whirlpool under electromotive force effect
Stream, owing to the impedance in eddy current loop is the least, strength of vortex is the biggest, makes eddy current loop produce the biggest heat
Amount, thus the support raceway axle portion 14, first in coil is supported the raceway shaft shoulder 15, second and supports raceway axle
Shoulder the 16, first support raceway shaft shoulder root circular arc 17 heats.
When alternating current is by the groove portion of thrust wheel, CURRENT DISTRIBUTION is that center density is little, closer to surface,
Density is the biggest.Due to square being directly proportional, so the maximum of heat also occurs in work of heat and strength of vortex
The surface layer of part, here it is the kelvin effect of sensing heating, utilizes this effect to carry out the groove portion of thrust wheel
Quickly heating.
The stalloy magnetic conductor being arranged on copper pipe is to utilize the notch effect of magnetic conductor can be the electricity in conductor
Stream is driven into the first support raceway shaft shoulder and first of thrust wheel and supports raceway shaft shoulder root circular arc, improves sensing
The efficiency of heating surface of device.
Cooling water enters at cooling water inlet 12, flows out at coolant outlet 8, absorbs thrust wheel of digging machine anti-
The heat being emitted back towards, plays the effect of protecting tool set-up.
In a word, the present invention realizes disposably to the support groove portion of thrust wheel of digging machine and the adjacent shaft shoulder on request
Carry out different depth heating, meet the deep layer heating that technology requires, decrease heating times, saved workman
Labour force, improves work efficiency.
Being more than one of embodiment of the present invention, protection scope of the present invention is not limited to above example, any etc.
Effect is replaced or similar conversion is all within protection scope of the present invention.
