Description
Technical field
The utility model relates to a kind of safety device, specifically refers to the one hand safety device against pressure for preventing from press device misoperation from weighing wounded disabling staff accident.
Background technology
Current press device as when hydraulic press, aerostatic press work because of machinery, apparatus failure or because of the tired maloperation of operator, generation such as presses down continuously, staff not yet withdraws from misoperations such as pressing down, cause the miserable accident that disables of hurting sb.'s feelings, in order to prevent press device casualty accident, prior art adopts hand safety device against pressure, monitored by infrared electro, after confirmation staff is withdrawn, then hydraulic control machine presses down; There is malfunctioning phenomenon in the reliability due to longtime running electronic safety device, causes very dangerous, and therefore, prior art exists the problems and shortcomings that longtime running is unreliable, be difficult to guarantee personal security.Separately, current hand safety device against pressure is applicable to slower drawing velocity, and the scope of application is narrower.
Utility model content
For solving the problem, the utility model provides a kind of hand safety device against pressure.
For achieving the above object, the utility model adopts following technical scheme to be: a kind of hand safety device against pressure, comprise frame and pressure actuated device, described frame is provided with counterdie, hand seat against pressure and the hand connecting rod against pressure be connected with hand seat detachability against pressure, described pressure actuated device is connected with patrix drift and hand connecting rod against pressure, between described patrix drift and counterdie, there is potential difference, buffering chute is provided with between described hand seat against pressure and hand connecting rod against pressure, normally closed switch is provided with in described buffering chute, buffering chute is provided with between described hand seat against pressure and hand connecting rod against pressure, normally closed switch is provided with in described buffering chute.
Also be provided with hand spring catch against pressure between described hand seat against pressure and hand connecting rod against pressure and be placed on the spring on hand spring catch against pressure.
Back-up ring is provided with in described buffering chute.
Described hand seat against pressure and hand connecting rod against pressure are connected by screw.
Described pressure actuated device is oil cylinder or pneumatic cylinder.
The beneficial effects of the utility model are: the utility model applies potential difference by upper and lower mould and is provided with normally closed safety switch; normally closed safety switch to detect between upper and lower mould whether conducting, and (workpiece is conductor; human body is insulator); cushion space is reserved when upper and lower mould contacts; reduce patrix drift at Contact and press down speed to strengthen systems axiol-ogy buffer time; to the safeguard protection of operating personnel, existing arm device against pressure is effectively avoided to there is malfunctioning phenomenon and produce the generation of security incident.
Accompanying drawing explanation
Fig. 1 is the utility model structure chart.
Fig. 2 is Figure 1A-A sectional view.
Mark illustrates: 1. hand connecting rod against pressure; 2. hand spring catch against pressure; 3. spring; 4. safety switch; 5. back-up ring; 6. hex screw; 7. hand seat against pressure; 9. patrix drift.
Detailed description of the invention
Refer to shown in Fig. 1-2, the utility model is about one hand safety device against pressure, comprise frame and oil cylinder (or pneumatic cylinder), oil cylinder and frame insulate, described frame is provided with counterdie, hand seat 7 against pressure and the hand connecting rod 1 against pressure be connected by hex screw 6 with hand seat 7 against pressure, 24V potential difference is applied between described patrix drift 9 and counterdie, described oil cylinder is connected with patrix drift 9 and hand connecting rod 1 against pressure, buffering chute is provided with between described hand seat 7 against pressure and hand connecting rod 1 against pressure, normally closed switch is provided with in described buffering chute, normally closed switch cover has back-up ring 5.When patrix drift 9 be pressed in be placed in workpiece on counterdie time, first normally closed safety switch 4 is triggered, send signal system to detect between upper and lower mould whether conducting (workpiece is conductor, human body is insulator), open the check-valves on hydraulic circuit simultaneously, hydraulic oil is led back to fuel tank (oil cylinder stops pressing down), finally determine that patrix continues to press down or oppositely backhaul according to testing result.When cylinder piston rod presses to punch. contact to workpiece, mutual slip can be produced between hand connecting rod 1 against pressure and hand seat 7 against pressure, trigger normally closed safety switch 4(now structure still leave space and do not kill), provide signal and start to detect between upper/lower die drift, whether to rely on workpiece and conducting (or insulation), if conducting, drift continues to press down work, if insulated, direction rises in drift change.
Above embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that the common engineers and technicians in this area make the technical solution of the utility model and improvement, all should fall in protection domain that claims of the present utility model determine.
Claims (5)
