AC power connect with magnet exciting coil and form closed circuit, alternating current is passed into magnet exciting coil, when being passed into excitation
When sense of current in coil changes, electromagnetic block is by with different polarity, when the polarity phase of electromagnetic block and permanent magnet
Meanwhile will be mutually exclusive between electromagnetic block and permanent magnet, permanent magnet will drive arc-shaped convex block to be moved to the direction far from electromagnetic block
It is dynamic, it when electromagnetic block is opposite with the polarity of permanent magnet, will attract each other between electromagnetic block and permanent magnet, permanent magnet drives arc-shaped
Convex block is moved to close to the direction of electromagnetic block, therefore when the direction for the alternating current being passed into magnet exciting coil constantly changes
When, permanent magnet will drive arc-shaped convex block up and down reciprocatingly to vibrate, and arc-shaped convex block drives Circular Nose Cutting Edge past to the burr at chamfering again
The cleaning of multiplex vibration.
In step (1), molding die is placed on to the underface of rose reamer, ensure that rose reamer processed molding die
Accuracy.
In step (2), numerically-controlled machine tool drives rose reamer to be moved down while rotating and is processed to rose reamer, chamfering
The speed of knife rotation is 200-300r/min, if the speed of rose reamer rotation is too fast, then will produce a large amount of heat on rose reamer
Amount, if the heat distributes the service life that can influence rose reamer not in time, if the rotary speed of rose reamer is excessively slow, then chamfering
Efficiency will reduce, while the speed that moves down of rose reamer is 0.5-3cm/s, if the speed that rose reamer moves down is too fast, then step
(3) Circular Nose Cutting Edge reduces the time cleared up at burr in, to which the cleaning effect to burr can be made bad, if under rose reamer

The light source at place will be radiated at the position of eyeglass upper, and light source will be received apart from the optoelectronic switch of piston crown farther out, at this time
The frequency for being connected on the AC power in magnet exciting coil circuit is higher, i.e., permanent magnet drives the frequency that Circular Nose Cutting Edge up and down reciprocatingly vibrates
It increases, Circular Nose Cutting Edge only needs the less time that the cleaning to burr can be completed, and the speed that rose reamer moves down at this time can be with
Comparatively fast, to improve the processing efficiency to molding die.
Further, in step (2), the rotating speed of rose reamer rotation is 200r/min, and the speed that rose reamer moves down is
0.5cm/s。
When the rotating speed of rose reamer rotation is smaller, the heat generated on cutting edge is less, and the heat of cutting edge is in work at this time
Fill in tail portion active force it is smaller, piston tail push piston crown it is smaller in the distance of working chamber indoor moving, so when install
Light source at hole will be radiated at the position of eyeglass lower, and light source will be received by the optoelectronic switch closer apart from piston crown, this
When be connected on AC power in magnet exciting coil circuit frequency it is relatively low, i.e., permanent magnet drives the frequency that Circular Nose Cutting Edge up and down reciprocatingly vibrates
Rate reduces, and Circular Nose Cutting Edge needs longer time that could complete the cleaning to burr, the speed for needing rose reamer to move down at this time
Slow down, to ensure the cleaning effect to burr.
Further, chip space is equipped between two neighboring cutting edge.Two cutting edges on cutter head are used for shaping mould
Tool carries out chamfer machining, and cutting edge will produce clast when being processed to molding die at the chamfering of molding die, generation
