Abstract
This involves a device (1, 6) for controlling a valve (2) for transmission of gas from a gas cartridge (3) in a combustion chamber in a gas-powered fastening apparatus, which comprises a solenoid (6) for controlling valve (2). It comprises a regulating circuit for stabilizing the discharge (Id) from said solenoid (6).
Description
In this manner, the present invention relates to a kind of control device that is used for the gas permeability valve of gas cartridge in the combustion chamber in pneumatic fastener, comprise valve control solenoid, in fact it comprises that adjuster circuit stablizes described solenoidal discharge.
Preferably, this device comprises at its output, is used for discharge diode that the solenoid electric energy stored is discharged when valve open, and wherein adjuster comprises at least one voltage adjustment diode with this discharge diode assembled in series.
In this case, voltage adjustment diode can be Zener diode, for the closing velocity of regulating this valve to required value, be selected from the function of puncture voltage or Zener voltage.
The invention still further relates to the pneumatic fastener that comprises control device of the present invention.
To better understand the present invention according to following to being used for description and accompanying drawing thereof according to the preferred implementation of the solenoid engine of pneumatic fastener of the present invention, wherein,
Fig. 1 is the sketch map of general control device that is used for the air intake valve of pneumatic fastener;
Fig. 2 is the sequential chart that comprises the multiple electric control that is used for valve that is produced by this control device according to of the present invention;
Fig. 3 is the I-E characteristic track that is used for discharge circuit;
Fig. 4 is the sketch map that is used for the control device of pneumatic fastener valve according to of the present invention;
Fig. 5 is the I-E characteristic track according to discharge of the present invention and regulating circuit;
Fig. 6 is the sequential chart that does not have the Control current and the voltage process of regulating circuit among the present invention at the solenoid end; And
Fig. 7 is according to the sequential chart in terminal Control current of control device and voltage process of the present invention.
With reference to Fig. 2, the time is to begin to calculate from the benchmark 0 that the control of being implemented by module 1 begins, and further is sent to the power supply of solenoid 6 by identical module 1 with electric current I c, and t1 is the moment that valve 2 is opened, and t2 is the moment of power-off.
Constantly t1 is a constant, and this is because the increase of electric current I, thus in the solenoid 6 of valve open its duration that reaches beginning threshold value Io very short.
For valve-off 2, according to one that closes in the closed curve, 13 or 14, t2 when the voltage on being added to solenoid 6 stops constantly, diode 7 is electric energy stored in the rapid release solenoid 6 more or less, and have only and the moment that valve 2 is closed when I reaches residual current If, just occurs, wherein the magnetic action of solenoid 6 can no longer compensate the effect of back-moving spring in the valve 2, promptly, at after date when variable, can be in meeting diode 7 close between the moment t3 of the discharge curve 13 of solenoid 6 and 14 characteristics and the t4.
By using the voltage-regulation Zener diode 9 of connecting with discharge diode 7 (Fig. 4), we can finish closing of valve 2 in the t5-t2 in discharge time at interval according to the curve 15 with bigger slope, so because curve 15 is shorter more stable, the time interval T that allows us to obtain to equal t5-t1 opens valve 2, more stable like this, and therefore measurable its allows for controlled.We should notice that the circulating direction of Zener diode 9 and discharge diode 7 is relative here.
Therefore, it is more accurate to enter into the quantity of gas of combustion chamber.
With reference to Fig. 3, indicatrix 21 and 22 representatives here are discharge diodes at discharge circuit 7, the electric current I d of middle circulation, as the function at the voltage V of solenoid 6 ends, expression is from the bending that be approximately 0.6 volt voltage threshold Vo place of diode 7 by beginning.Be known as all diodes of regulating diode and have the threshold value diode that is approximately this numerical value.
Discharge diode 7 allows the energy of storage in solenoid 6 to discharge by electric current I d, and the value of electric current I d equals Vo/L, and wherein L is the reactance of solenoid 6.
Shown in Figure 5 is the i-v curve characteristic, the dotted line 21-22 of expression discharge diode 7, the dotted line 33-31-32 of the expression Zener diode 9 relative with discharge diode 7 and the solid line 34-35-36 that represents these two kinds of diode characteristics.
In the highest direction of frequency of utilization, because Zener diode 9 is relative with discharge diode 7, two kinds of diodes have identical characteristic and have is 0.6 volt threshold value Vo, here-and Vo represents Zener diode 9.
Because two kinds of diodes 7 and 9 connect, in Zener diode 9, there be not electric current I d to circulate on the blocking direction of discharge diode 7, under identical condition, do not exist to allow opening of module 1 by-pass valve control 2 as Zener diode 9.
On the other hand, on the blocking direction of Zener diode, promptly here, with top the same reason, on the common direction of discharge diode 7, the indicatrix of Zener diode 9 is represented the bending at Zener voltage Vz place, or puncture voltage, is about 6.8 volts.
Because two kinds of diode series connection, by the voltage of Zener voltage decision solenoid 6 ends, therefore the value at moment its discharging current Id that valve 2 is closed is substantially equal to (Vo+Vz)/L.
Therefore, at least ten times greatly of the stiffness of indicatrix 15, the inaccuracy of the moment t5 when valve 2 is closed changes with same ratio, and is little at least ten times.The result enters into that the quantity of gas of combustion chamber is more accurate to be determined.
Fig. 6 and 7 well shows before Zener diode 9 is installed and the function difference between the control device afterwards.
Among Fig. 6, be solid line at sequential Figure 40 of solenoid 6 terminal voltage V, Figure 45 of electric current I c and Id is a dotted line.Cross-hatched surface 41 correspondences are by the image of the energy of diode 7 releases.It is with launching as time of time interval T, terminates in more late moment t3 or the t4 of moment t2 when being activated with respect to valve closing control 2.
On the other hand, among Fig. 7, the shadow region 43 of the image of the corresponding energy that is discharged by diode 7 be the expansion of voltage, and it terminates in very near valve closing as time interval T and controls 2 the moment t5 of moment t2 when being activated.
We can be based on puncture voltage or Zener voltage Vz selection Zener diode, in order further to increase of short duration time interval t5-t2 and therefore to regulate the accuracy of valve-off 2 and the numerical value that speed is extremely expected.Vz can select between about 6.8 and 20 volts.In fact, the maximum of electric current I d equals the electric current (Id max=Vbattey/Rsolenoid) between t1 and the t2.The maximum of electric current I d does not also rely on Zener voltage.Depend on the gradient of discharging current but not the maximum of electric current from magnitude of voltage to Zener voltage.If Zener voltage is elected as greater than 6.8V, the shut-in time between t2 and the t5 almost can not reduce at all again, and this is that the translational speed in the spring limits (mechanical constraint) because the closing velocity of valve 2 is reset.
Replace Zener diode, we can increase n the adjusting diode Di (not shown) of connecting with discharge diode 7, and its electric current I has than an above-mentioned much bigger value (n+1) Vo/L, and the release of energy is faster also more stable.But, cause the adequate stability of T for the closing velocity that obtains valve 2 will have more diode.This solution is not too interested one.
