Technical background
In present stage production, the more traditional machining of Sheet Metal Forming Technology has the economical with materials and the energy, the efficient height can make these advantages of product that machining is beyond one's reach to not high the reaching by various moulds application of operator's specification requirement, thereby its purposes more and more widely.
Present existing punch press, its stamp switch is the electromagnetic relay switch, electromagnetic relay is generally by electromagnet, armature, spring leaf, contacts etc. are formed, its operating circuit is made of low-voltage control circuit and high-pressure work circuit two parts, as long as add certain voltage at the coil two ends, will flow through certain electric current in the coil, thereby generation galvanomagnetic-effect, armature will overcome the pulling force of return spring and inhale to iron core under the effect of electromagnetic attracting force, thereby drive the movable contact and stationary contact (normally opened contact) adhesive of armature, behind coil blackout, the suction of electromagnetism also disappears thereupon, armature will return original position at the reaction force of spring, make movable contact and original stationary contact (normally-closed contact) release, adhesive like this, discharge, thereby reached the conducting in circuit, the purpose of cutting off, using the shortcoming of relay switch is when electromagnetic relay is worked, can produce the big electric current of moment, thereby cause burning out easily relay, and when the voltage instability timing, electromagnetic relay magnetic force instability causes the frequency of stamp machine work also unstable, and the stability and the security of operation are bad, the stable quality problems that with great difficulty do not influence the product punching press, the bad meeting of security produces threat to employee's personal safety.
The utility model content
The purpose of this utility model is to provide a kind of stability and the good mechanical press's gate-controlled switch device of security.
In order to realize this purpose, the utility model has adopted following technical scheme:
A kind of mechanical press gate-controlled switch device, comprise drift, eccentric wheel, the punch press power source, flywheel block and braked wheel, described drift is connected by slide block mechanism with eccentric wheel, be connected by connecting rod between described eccentric wheel and the described punch press power source, described connecting rod is provided with the flywheel block, described flywheel block below is provided with braked wheel, also comprise pedal gear, described pedal gear comprises pedal, cross bar, interlock pole and A-frame, described pedal and A-frame are located at the cross bar two ends respectively, described cross bar is provided with intermediate contact, described intermediate contact is connected with ground, and described interlock pole is connected with described cross bar, and described interlock pole top is provided with tooth bar, described tooth bar position is provided with gear, and described gear is connected with braked wheel.
Preferably, cross bar described in the utility model is provided with back-moving spring, and described back-moving spring is fixed on the described cross bar.
Preferably, tooth bar described in the utility model agrees with mutually with described gear size.
Preferably, gear described in the utility model is connected by connecting shaft with braked wheel.
The utility model contrast prior art has following advantage: the utility model is simple in structure, uses mechanical pedal control can effectively grasp the punch press control rate, avoids unstability and insecurity in the operating process, and easy to operate, cost is low, in being widely used in producing.
Description of drawings
Accompanying drawing 1 is the utility model structure chart.
The specific embodiment
Referring now to accompanying drawing, further describe the utility model.
As shown in Figure 1, a kind of mechanical press gate-controlled switch device, comprise drift 1, eccentric wheel 2, punch press power source 3, flywheel block 4 and braked wheel 5, drift 1 is connected by slide block mechanism 100 with eccentric wheel 2, be connected by connecting rod 200 between eccentric wheel 2 and the described punch press power source 3, connecting rod 200 is provided with flywheel block 4, flywheel block 4 belows are provided with braked wheel 5, also comprise pedal gear 6, pedal gear 6 comprises pedal 610, cross bar 620, interlock pole 630 and A-frame 640, pedal 610 and A-frame 640 are located at cross bar 620 two ends respectively, and cross bar 620 is provided with intermediate contact 621, and intermediate contact 621 is connected with ground, interlock pole 630 is connected with cross bar 620, interlock pole 630 tops are provided with tooth bar 631, and tooth bar 631 positions are provided with gear 632, and gear 632 is connected with braked wheel 5.
For pedal gear 6 can automatically reset, cross bar 620 is provided with back-moving spring 621 in the present embodiment, and back-moving spring 621 is fixed on the cross bar.
In order more effectively and more effortlessly to drive braked wheel 5, present embodiment middle rack 631 agrees with mutually with gear 632 sizes.
For more convenient driving braked wheel, present embodiment middle gear 632 is connected by connecting shaft 500 with braked wheel 5.Lever principle also claims " lever equilibrium condition ".Make lever balance, the size that acts on two power (with force, fulcrum and resistance point) on the lever follows their arm of force to be inversely proportional to.Power * power arm=resistance * resistance arm is expressed as F1 11,=F2 12 with algebraic expression.In the formula, F1 represents power, 11 expression power arms, and F2 represents resistance, 12 expression resistance arms.Can find out that from following formula desire to make lever to reach balance, power arm is several times of resistance arm, power is exactly the part of resistance.
The utility model is when work, the effect of pedal gear 6 has utilized lever principle, the strength of energy save operators, when pin is stepped on pedal 610, pedal gear 6 will spur tooth bar 631 and move downward, tooth bar 631 drives braked wheels 5 and rotates counterclockwise, when braked wheel 5 turn-ofves, flywheel block 4 stop disappearance, eccentric wheel 2 will clockwise rotate under the effect of punch press power source 3, eccentric wheel 2 drives drift 1 and moves downward when rotating, finish a stamp action, unclamp pedal 610 after, tooth bar 631 moves up under the effect of back-moving spring 621, make braked wheel 5 returns, after eccentric wheel 2 turned around, its flywheel block 4 meeting quilts braked wheel of return blocked, stop drift to dash for 1 time, when needs again towards the time, just can step on pedal 610 again, repeat above action.
Above-described the utility model embodiment does not constitute the qualification to the utility model protection domain.Any modification of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the claim protection domain of the present utility model.
