Description

The punching machine safety control device

Technical field: the utility model relates to a kind of device of the person's safety of protecting the operating punch machine.

Background technology: general punching machine safety device all adopts infrared or the photodetection mode, exploration operation person hand position, and by floor push and solenoid control punch press, prevent to dash under the slider of punch.In practice, the environment for use of punch press generally has a large amount of dust or greasy dirt, and is infrared or photoelectric probe is contaminated easily, poor reliability, and also uncontrollable at all slider of punch connects towards stroke when the operation mistake is stepped on, and can not shield.Because the inherent characteristic of infrared or photoelectric probe, it is big that the space that needs is installed, the influence operation, the control circuit complexity, in existing common punch press repacking inconvenient, cost is higher.

Summary of the invention: at the deficiencies in the prior art, it is a kind of rational in infrastructure that the utility model provides, and uses reliably punching machine safety control device easily.

The utility model comprises a control circuit, is provided with a controllable execution device at the bent axle clutch place of punch press, and it is connected with control circuit, and the action piece of this controllable execution device and bent axle clutch engagement constitute the clutch locking mechanism; Be provided with controllable clutch between the pedal of punch press and the pulling rope, be provided with displacement transducer with the position of bent axle or slide block correspondence, also be provided with state selecting switch on the workbench of punch press, controllable clutch, displacement transducer and state selecting switch all are connected control circuit.

The utility model not only can be thrown off controllable clutch automatically when operation, prevent that the foot-operated company of generation that slips up from dashing, but also can lock the bent axle clutch of punch press, avoid bent axle clutch on-off thoroughly not produce the situation of misoperation fully, even also can in time control the action of slider of punch towards work the time, security performance is very high, and it is reliably convenient to use, rational in infrastructure, can in various punch presses, install and use.

Further specify the utility model below in conjunction with drawings and Examples.

Description of drawings: Fig. 1 is the view of installing and using of embodiment;

Fig. 2 is that the local A of Fig. 1 is to view;

Fig. 3 is the circuit block diagram of embodiment;

Fig. 4 is the schematic diagram of clutch locking mechanism among Fig. 1;

Fig. 5 is another form schematic diagram of Fig. 4;

Fig. 6 is another form schematic diagram of Fig. 4.

Embodiment: as shown in Figure 1 to Figure 3, punch press is provided with control circuit 4, bent axle clutch 3 places between punch press flywheel 14 and bent axle are provided with a controllable execution device 1, and it is connected with control circuit 4, and the action piece 2 of this controllable execution device 1 and bent axle clutch 3 cooperate formation clutch locking mechanism.Be provided with controllable clutch 6 between the pedal 5 of punch press and the pulling rope 7, be provided with displacement transducer 8 with the position of bent axle or slide block 15 correspondences, 13 also are provided with state selecting switch 9 on workbench, and controllable clutch 6, displacement transducer 8 and state selecting switch 9 all are connected control circuit 4.Control circuit 4 can adopt the mode of common single-chip microcomputer and corresponding control software to realize, this mode realizes that simply control is revised more convenient, also can adopt other circuit common form certainly.

In practice, punch press is generally operational in one-shot, point dashes or connect towards state, present embodiment also is provided with left and right two and connects control circuits 4 by touching switch 10 on the workbench 13 of punch press, can increase by one left hand and right hand step like this by touch-control system, make operator's hand leave danger position, further improve security.Present embodiment also is provided with fault alarm 11 and connects control circuit 4 on punch press, 16 in the motor of punch press passes through contactor 12 and connects control circuits 4, like this when bent axle clutch 3 can't reset or lock, fault alarm 11 can fault alarm, the motor 16 of 12 cut-out punch presses of contactor.

When needs punch press one-shot is worked, the good workpiece of clamping, state selecting switch 9 is transferred to the one-shot state, situation needs two hands according to processing touch logical left and right by touching switch 10 or touching logical one simultaneously, make operator's hand be placed on home naturally, control circuit 4 is just opened controllable execution device 13 releases of bent axle clutch so always, after the operator depressed pedal 5, punch press can start.When bent axle or slide block 15 move certain position, when generally being 1/4 stroke, displacement transducer 8 induced signals, control circuit 4 cuts out controllable execution device 1, bent axle clutch 3 is in the lock state for the treatment of, controllable clutch 6 discharges simultaneously, even the operator can even not dash because pedal 5 is loosened in fatigue or maloperation yet like this.When resetting after slide block dashes for 15 times, controllable execution device 1 has cut out, and action piece 2 is with 3 lockings of bent axle clutch, and promptly this moment, flywheel 14 and bent axle can't link, and slide block 15 can not dash down again, after the operator unclamps pedal 5, finishes the one-shot process.Repeat the operation of front, just can restart the one-shot process.

When needs punch press point towards the time, adjustment state selector switch 9 and since point when dashing operation both hands can not be placed on danger position naturally, this moment is left and right closes by touching switch 10 controlled circuit 4.When pedal 5 was depressed, punch press started, and the course of work is with the one-shot state.After the operator unclamped pedal 5, end point was broken through journey, and pedal 5 depresses again, and starting point is broken through journey again.

As needs Lian Chongshi, same adjustment state selector switch 9, touch logical left and rightly by touching switch 10 or one of them, controllable execution device 1 is opened, 3 releases of bent axle clutch, depress pedal 5, punch press starts, and this moment, punch press carried out punching press always continuously, have only the pedal 5 of relieving after, bent axle clutch 3 just can be locked, and the company of finishing breaks through journey.

In practice, punch press bent axle clutch 3 is generally used two kinds of reaping hook formula or turn key formulas, is the locking mechanism of reaping hook formula bent axle clutch 3 as Fig. 4 and Fig. 5, the latched position difference of action piece 2, the convenient installation.Be illustrated in figure 6 as the locking mechanism of locking turn key formula bent axle clutch 3, in the reality other corresponding form can also be arranged certainly.The controllable execution device 1 that is installed on the punch press can be electromagnet or pneumatic or the part that surges, and controllable clutch 6 is electromagnetic type or pneumatic type or the formula clutch that surges.Generally all adopt Electromagnetic Control more convenient, need not external source of the gas or conduit under fluid pressure.
