Abstract

The utility model relates to a press with high security, and belongs to the press manufacturing technology field. The utility model is mainly characterized in that a 4th level security control module is adopted, each input port of the 4th level security control module is connected with an emergency stop button, a two-handed control, a safety door, a safety grating, a cam monitor and the signal port of a duplex safety valve through a terminal connection mode, each output port of the 4th level security control module is connected with the input end of the duplex safety valve, the emergency stop button, the two-handed control, the safety door, the safe grating, etc. through the terminal connection mode, and all the safe controls adopt a double loop control with monitoring function. The press has the advantages that the structure is simple and easy to understand, no specific programming practice is required, the strong diagnostic function is possessed, the safety grade reaches the requirement of the European Security Level 4, the security of the working personnel and the machine is greatly ensured, and the working personnel and the machine are protected.

Description

The forcing press of high security

Technical field

The utility model relates to a kind of forcing press of high security, belongs to pressure mechanism technology for making field.

Background technology

In the forcing press industry, more and more pay attention to employee's personal safety and to the safe handling of forcing press itself.Common PLC is open loop control, can not self provide feedback, and security can not get guaranteeing; Though use the hardwire of individual security relay to carry out security control, cost is high, design is loaded down with trivial details and fault diagnosis is difficult; If use simple safety PLC, then can not obtain the highest cost performance.Native system adopts special press module to make that the security control of forcing press is more flexible and convenient, avoids the generation of accident.

Summary of the invention

The purpose of this utility model is that to adopt common PLC at existing forcing press be open loop control, can not self provide feedback, and the deficiency that security can not get guaranteeing provides security control more flexible and a kind of forcing press of high security easily.

The purpose of this utility model is achieved through the following technical solutions, a kind of forcing press of high security, it is characterized in that adopting the level Four safety control module, each input port of level Four safety control module connects the signal end of scram button, both hands control, safety door, safe grating, cam monitoring and double safety valve by the terminal connections mode, and the delivery outlet of level Four safety control module connects the input of double safety valve by the terminal connections mode.

The level Four safety control module can adopt PNOZ m2p, PNOZ mi1p, PNOZmo4p.

The device double loop control that each input port, delivery outlet and the access of level Four safety control module picks out.

The utility model adopts modular structure, uses flexibly; Safe controls such as scram button, both hands control, safety door, grating have all adopted the double loop control of band monitoring function, and ifs circuit occurs unstable, perhaps wherein a road mistake appears, self can cut off circuit, play the effect of protection; Whether the pulse detection function can detect power pulse consistent with test pulse, if inconsistent, safe control such as scram button will move so, and forcing press will stop; Operator scheme two states can not occur in four kinds of states of forcing press (adjusting microinching, single, continuously, stop) being included in simultaneously in its operating process, can avoid the generation of accident; The cam monitoring function plays the real-time monitoring to surpassed distance cam, up cam, prevents the appearance of nonstandard action; Can also monitor the time of one stroke and the pulse number of one stroke in addition; The utility model is simple to operate understandable, need not special programming knowledge, has powerful diagnostic function, and safe class has reached the requirement of European safe class 4, has guaranteed the safety of staff and machine greatly, protection operating personnel and machine.

Description of drawings

Fig. 1 is that the utility model circuit connects block diagram;

The specific embodiment

Further specify the utility model in conjunction with the accompanying drawings and embodiments, the level Four safety control module is set on the utility model forcing press, the level Four safety control module can adopt the level Four safety control module (model is: PNOZ m2p, PNOZ mi1p, PNOZ mo4p) of pilz company, each input port of level Four safety control module connects the signal end of scram button, both hands control, safety door, safe grating, cam monitoring and double safety valve by the terminal connections mode, and the delivery outlet of level Four safety control module also is the input that connects double safety valve by the terminal connections mode; The device double loop control that each input port, delivery outlet and the access of level Four safety control module picks out.

Claims

1, a kind of forcing press of high security, it is characterized in that adopting the level Four safety control module, each input port of level Four safety control module connects the signal end of scram button, both hands control, safety door, safe grating, cam monitoring and double safety valve by the terminal connections mode, and the delivery outlet of level Four safety control module connects the input of double safety valve by the terminal connections mode.

2, the forcing press of high security according to claim 1 is characterized in that the level Four safety control module can adopt PNOZ m2p, PNOZ mi1p, PNOZ mo4p.
