Description
The invention belongs in the punch ram processing and prevent a kind of emergency brake device that human injury takes place.
At present, the traditional theory of science and technology, industrial quarters is thought: " for the press machine of positive clutch, because ram travel Once you begin, a circulation is promptly carried out in work, and braking midway is difficult to realize, so photoelectric protector only starts as anti-limited slip block.This for some number of strokes height (〉=120 times/minute) to have a press machine of positive clutch very safe, even because slide block reaches between the hazardous area after starting, also have little time to enter mould, slide block finishes soon
*Working stroke." (see " the C-frame press design " the 253rd page of Jinan casting forging research institute distribution, finish
*One speech original text is " beginning ", should be clerical mistake, and this change done in quoted passage).In fact; by following punching machine safety device negated to some extent: the design of Jiangsu labor protection research institute; the photoelectricity punching machine safety device that Qingjian River tractor plant makes; Harbin Institute of Technology's design; the HF-C type infrared rays secure ram protector that the stepless tiny motion rigid clutch punch press that forging press factory, Cangzhou, Hebei produces and Yixing, Jiangsu county electrical apparatus factory produce; " the novel punching machine safety device " that No. 85200209 utility model patents are announced; the JBH series punching machine safety device that Nanjing Electronic Tube Factory produces, Shanghai Communications University; Shanghai mould research institute; the QF-1 type punch press series safety device for emergency braking of the common development of Shanghai Lighter Factory.
Positive clutch punch press emergency brake device is more representational to be the emergency braking safety mechanism that Shanghai Lighter Factory produces, adopt infrared technique and friction disc gear formula structure, through expert appraisal, stable drive, braking is sensitive, but stepless brake (is seen technical market newspaper on August 13rd, 1985) in the arbitrary position." through city other unit trial run one year over, proved stable performance, braking sensitivity reliably, the emergency braking performance is in leading domestic status, and reaches advanced world standards." (seeing Shanghai Lighter Factory, Shanghai Communications University, Shanghai Die Technology Inst.'s order).In fact; owing to be not to adopt solid state relay energising emergency braking; the electromagnet stroke is generally greater than 10 millimeters; the electric current that produces in the randomness of consideration energising and the inductance lags behind factors such as voltage; response time (from sending emergency brake signal to the required time of emergency braking mechanism stop motion) is still longer; for the small-sized punch press degree of depth of extending is the operation unprotect effect of extending of 2/5ths ram travels, and braking torque is less.So-called braking is sensitive reliable, does not reach the level that all positive clutch punch presses are all met the demands; Do not have the function that cuts off self-lock, run counter to the program that ordinary accident is handled; Emergency braking all may take place in the slide block down process, and the unnecessary emergency braking action and the action of losing efficacy are arranged, and must change some operating habit, influences operating rate; 900 yuan/platform of QF-1-63 type emergency brake device mechanical part, structure are complicated, make difficulty; The QF-1-63 type is installed 432 yuan of service charges (needing about 144 hours of installation work-hour), and difficulty is installed.
Purpose of the present invention is exactly further to improve the performance of emergency brake device, to adapt to the production needs.
Principle of the present invention is the slide position accurately to be punished be anti-error start-up point, the emergency braking district, district that allows to come in and go out, and effective parking area, the backhaul district does not influence operating habit so that adopt the corresponding protection measure; Dwindle short response time as far as possible and take off the key time (reducing to take off the key corner), to enlarge protection domain.
Below with reference to accompanying drawing invention is further described.
Fig. 1 is the schematic representation of slider position sensor layout formula.
Fig. 2 is used for the emergency braking driving mechanism of rotating key clutch punch press and the scheme of maneuver of emergency braking mechanism.
Fig. 3 is the work schematic representation of slider position sensor at a cycle period.
Fig. 4 is the cut-away view that is used for the emergency braking mechanism of sliding pin clutch punch press.
Fig. 5 is the front view that is used for the emergency braking mechanism of sliding pin clutch punch press.
The present invention is by slider position sensor, the brake hard driving mechanism, and emergency braking mechanism forms.
As shown in Figure 1, tongue tube group 1 and tongue tube group 2 relative stationary distribution and can be fixed in lathe bed around the main shaft rotation center adjustment in same plane, and permanent magnet 3 rotates with main shaft.
Referring to Fig. 1, Fig. 3, when slide block during at top dead-centre A, tongue tube group 1 is connected, and this moment, the slide position judging circuit sent out enabling signal anti-error, and (take single operation as example) promotes corresponding control circuit, in case " mistake is stepped on " and " a chain of car ". After slide block leaves top dead-centre A, tongue tube group 1 is not write disconnection, when permanent magnet 3 moves to the B point, tongue tube group 1 disconnects, the slide position judging circuit is felt nervous and is suddenly braked district's signal, if this moment, hand entered the Photoelectric Detection district, the brake hard drive circuit is worked immediately, promote driving mechanism, realize brake hard. If hand does not enter the Photoelectric Detection district at this moment, slide block continues motion, and to the C point, tongue tube group 2 is connected, and judging circuit is no longer felt nervous and suddenly braked district's signal. To the E point, tongue tube group 2 disconnects, and the C point is effective parking area to the E point, if the slide block stop position surpasses the E point, judging circuit is sent out the brake fade signal. The F point can not enter the peak of mould for hand, and C point to F point is photoelectricity safe distance protection zone, after the C point, gets back to the A point through the G point, is the backhaul district, and brake hard does not take place. Slide block has been crossed bottom dead centre G to the p point symmetrical with minimum safe altitude E point, until top dead-centre A arrives the B point again, is the district of freely coming in and going out.
Slider position sensor removes dry reed-pipe group 1 and dry reed-pipe group 2 relative fixed, is distributed in the same plane, also it can be distributed on the cylinder of same garden; Both can adopt dry reed-pipe group 1 to disconnect the back is the emergency braking district to dry reed-pipe group 2 connection previous crops, also can establish a dry reed-pipe in addition, connects as the emergency braking district with it; The break-make of dry reed-pipe also can adopt magnetic shielding mode etc.
In a word, the setting of dry reed-pipe is wanted and can be divided into residing lane place in dust cycle of slide block: the A point is anti-error start-up point,
Distinguish for allowing to come in and go out,
Be the emergency braking district,
Be effective parking area,
Be photoelectricity safe distance zone of protection,
Be the district of freely coming in and going out,
Be the backhaul district.
Fig. 2 is the state when emergency braking takes place.
This break is the band brake of solenoid actuated.The electromagnet of driving mechanism has two, and main electromagnet 5 strokes are 6 millimeters, and band brake slack list power is provided, and it is less to pay electromagnet 4, plays the releasing effect.Locking bail 8 plays the mechanical self-latching effect, and produces band brake slack list power with adjusting spring 14. Spring 7,13 is a Returnning spring, gap between clamping strap 18 and the Hough brake disc 19, adjust by adjusting lock nut 16, safety washer 15, and the working pressure that makes spring 14 is greater than 2 times of main electromagnet 5 suction, when locking bail 8 locking, the guide pin bushing on the lever (lever ratio was got 1: 1) 12 leaves the locking nut 16 about 1 millimeter on the right.The Hough brake disc 19 of emergency braking mechanism is contained on the main shaft, and (can relatively rotate) is placed on the left side or the right of key tail, and two shelves key pins 20,21 are arranged on it, blocks the key tail; Perhaps, shelves key pin 20 is contained on the key tail, near the gyration center of turn key, on Hough brake disc 19, opens a groove (shown in Fig. 2 dotted line) as far as possible, grade key pin can be free to slide in groove, take off the key corner with minimizing.
When slider position sensor sends emergency braking district signal, hand is again when mould moves, and the drive circuit fast driving electromagnet energising work of being made up of ac solid relay just can make armature motion being not more than in time of 10 milliseconds.(or adopting capacitance energy storage) by the quick soaking magnetic of direct-current solid-state relay.If use MQ
1-5132 electromagnet, armature and other moving element reduced mass are less than 2kg, and electromagnetic attraction is about 20kg at 6 millimeters places of stroke, and the reaction force of spring 7,13 is 3kg, so armature can be 83.3 meter per seconds with minimum
2Acceleration movement (also do not consider that electromagnetic attraction reduce and increase) with adhesive distance, through 10 milliseconds, armature just can move 4 millimeters, band brake is started working, slack list power is provided by electromagnetic attraction, this moment, armature had the speed of 0.83 meter per second, obviously impact too big (having surpassed 0.16 meter per second) when the armature adhesive, armature continues motion, and spring 14 is started working, play buffer function, speed is no more than 0.16 meter per second when making the armature adhesive, and the power that produces negative acceleration must be provided by spring 14, so the working pressure of spring 14 can be worked under the condition greater than electromagnetic attraction, produce powerful slack list power, the drag angle of break is reduced.Do not increase lever ratio and adopt, increase the work of electromagnet stroke and increase slack list power.When armature motion to 5 millimeter, locking bail 8 is under the effect of spring 6, hook the locking plate 9 that is fixed on the pull bar 10, main electromagnet just can cut off the power supply, this moment is by locking bail 8 and spring 14 actings in conjunction, by flexible cable 11, lever 12, produce slack list power about 40kg (in fact armature motion 4 millimeters time), drag angle is less than 1 °.The size of slack list power needs only the locking nut of regulating on the adjusting screw rod 17 16, can adjust very easily.When Hough brake disc 19 stops operating, take off key and begin, block key pin 20,21 is when the diagram solid line position, and main shaft need turn over about 30 ° approximately just can take off key, and block key pin 20 needs about 20 ° approximately when the diagram dotted line position.After taking off key, the former break acting in conjunction of quiet moment of torsion of this break and lathe realizes the slide block emergency braking.Use according to reality, depend merely on this break, also can make slide block emergency braking reliably.
In sum; from emergency brake signal; till stopping operating to band brake; response time is not more than 20 milliseconds, is example with J23-6.3 type punch press, and safe altitude is got the 12-18 millimeter; for the stamping-out operation; but emergency braking protection domain α is about 80 °, be the operation of extending of 2/5 ram travel for the degree of depth of extending, but protection domain α also can reach about 30 °.The protection domain of big punch press is then bigger.
If the left side or the space, the right of key tail are less, do not adorn brake disc, can use the sprocket wheel chain transmission instead, break still is a band brake.
For sliding pin clutch punch press, as Fig. 4, shown in Figure 5, Hough brake disc 19 is enclosed within on the sliding sleeve, its inwall have an out of stock chamber 24(on one side for the plane of parallel axes, another side is the inclined-plane), Hough compression plate 22 is placed restrictions on Hough brake disc 19 and is moved axially, and former sliding pin afterbody adds a pin 23, when emergency braking took place, sliding pin was pulled out by the inclined-plane on Hough brake disc 19 inwalls and is realized emergency braking.
The kind of drive of the present invention has two kinds of direct transmission and chain-driven, and the direct transmission that directly is enclosed within on the main shaft with the Hough brake disc is the best.
The installation position of block key pin of the present invention is equipped with two kinds, is contained in key tail side with the block key pin, is best near its gyration center as far as possible.
Slider position sensor of the present invention has multiple, and with dry reed-pipe group 1, dry reed-pipe group 2 relative fixed are distributed in the same plane to best.
Response time of the present invention, drag angle reached 1 ° less than 20 milliseconds, and taking off the key corner is about 20 °, and the emergency braking protection domain is big, is applicable to the positive clutch punch press of various tonnages; The present invention has mechanical self-latching mechanism, emergency braking (back) takes place be not afraid of outage: slider position sensor of the present invention can accurately be distinguished the danger signal classification, thereby can adopt the corresponding protection measure respectively, therefore action accurately must not change operating habit; Mechanical part of the present invention is no more than 300 yuan, and is easy to manufacture; Installation fee is less than 100 yuan, installs easily.
