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 speed of shifting is excessively slow, then also results in the decline of processing efficiency.
In step (3), optoelectronic switch is set to be closed using the principle of reflection of light, and then AC power is connected on magnet exciting coil
Circuit, according to Ampere's law, when being passed through the electric current of different directions to magnet exciting coil, electromagnetic block is by with different polarity, so
Utilize that there is a natural attraction between the sexes afterwards, the principle that identical charges repel each other so that mutually exclusive and attract each other two kinds between electromagnetic block and permanent magnet
In the case of constantly convert, finally so that permanent magnet drives arc-shaped convex block up and down reciprocatingly to vibrate, Circular Nose Cutting Edge is past to being carried out at burr
The cleaning of multiplex vibration.
When rose reamer process velocity is very fast, it is shorter that Circular Nose Cutting Edge acts on the time at burr, needs on Circular Nose Cutting Edge at this time
Under frequency of reciprocating vibration increase, to ensure the cleaning effect to burr, the heat that cutting edge generates at this time is more, piston crown
It is larger in the distance of working chamber indoor moving, so that light source will be radiated at the position of eyeglass upper, sent out at this time through eyeglass
Light after penetrating will be received apart from the optoelectronic switch of piston crown farther out, the AC power being linked at this time in magnet exciting coil circuit
Frequency increase, i.e., permanent magnet drives the frequency up and down reciprocatingly vibrated of Circular Nose Cutting Edge to increase so that Circular Nose Cutting Edge to burr at
Cleaning effect is more preferable.
When rose reamer process velocity is slower, Circular Nose Cutting Edge acts on that the time at burr is longer, and Circular Nose Cutting Edge only needs at this time
Can meet the cleaning effect to burr with the smaller frequency up and down reciprocatingly vibrated, at this time cutting edge generate heat compared with
Few, piston crown is smaller in the distance of working chamber indoor moving, so that light source will be radiated at the position of eyeglass lower, this
When light after eyeglass emits will be received by the optoelectronic switch closer apart from piston crown, be linked at this time in magnet exciting coil circuit
AC power frequency add it is low.
The effect of this programme is:1, this programme, will be through installation using the principle of reflection of light when being processed to chamfering
The light that light source is sent out at hole is radiated on eyeglass, and the light after lens reflecting is received by optoelectronic switch again, and optoelectronic switch receives letter
Number and AC power connected with magnet exciting coil and form closed circuit, using magnet exciting coil be passed through in the current direction that is passed through
Variation so that both electromagnetic block and permanent magnet have identical or be different polarity, so that between electromagnetic block and permanent magnet
Active force that is mutually exclusive or attracting each other is generated, under the active force, permanent magnet drives the Circular Nose Cutting Edge on arc-shaped convex block
Upper and lower continuous reciprocating movement, Circular Nose Cutting Edge will constantly clear up the burr at chamfering during moving up and down, therefore this
When to molding die chamfering, Circular Nose Cutting Edge also completes during moving back and forth up and down to the hair at chamfering the rose reamer of scheme
The continuous cleaning of thorn is solved the problems, such as to also need to artificial removal's burr after the completion of chamfering in traditional processing mode, effectively be carried
The high processing efficiency of molding die, reduces the labor intensity of worker.
2, the speed that this programme can also be processed according to rose reamer automatically adjusts frequency of the Circular Nose Cutting Edge to deburred, when
When rose reamer process velocity is fast, Circular Nose Cutting Edge accelerates the frequency of deburred, and when rose reamer process velocity is slow, Circular Nose Cutting Edge is to hair
The cleaning frequency deceleration of thorn, therefore this programme can effectively be ensured by the adjustment of the frequency moved back and forth automatically to Circular Nose Cutting Edge
To the cleaning effect at burr.
3, the mobile dependence of this programme piston tail is the heat transfer that is generated on cutting edge to rose reamer, and to live
The air heating for filling in intracavitary, pushes piston to move again using hot-air, therefore on the one hand heat that this programme can generate cutting edge
Amount quickly consumes, and avoids the temperature of cutting edge excessively high, on the other hand realizes the recycling of energy.
Further, in step (2), the rotating speed of rose reamer rotation is 300r/min, and the speed that rose reamer moves down is
3cm/s.When the rotating speed of rose reamer rotation is larger, the heat generated on cutting edge is more, and the heat of cutting edge is in piston at this time
The active force of tail portion is larger, piston tail push piston crown it is larger in the distance of working chamber indoor moving, so when mounting hole
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
Clast will be in the chip space between being collected into two cutting edges.
Further, it is connected with the second bullet that Circular Nose Cutting Edge can be made to offset with molding die between arc-shaped convex block and installation chamber
