5.1 The action of the cylinder mold

Die cylinder whereabouts: solenoid YA01 was 1 s, mold cylinder is communicated with the air cylinder mold cavity, by its own gravity drop, the magnetic switch SP02 is switched on; mold cylinder reset: electromagnet YA02 power 1 s, cylinder mold mold inferior connected to gas source, rising return in suit, the magnetic switch SP01 is connected.

5.2 cylinder action

Fast forward: pressurized cylinder solenoid YA03 was 1 s, air pressure cylinder into the forward port, the pressure cylinder down quickly, by adjusting the throttle valve can get ideal fast speed, close to the switch JK02 is switched on to forward position; boosting cylinder: electromagnet YA05 electricity, gas into the pressurized cylinder pressure port, boosting cylinder down the output pressure regulating valve and the throttle valve can get ideal (50 k N) and the turbocharger speed, pressure relay YK02 is connected with the pressurization pressure cylinder in place; return: YA05 loss of electricity, electromagnet YA04 1 s, pressure port and fast forward port and atmospheric pressure cylinder is communicated with the air return port 2 into the pressurizing cylinder, the pressure cylinder rises back in suit, close to the switch JK01 is switched on.

5.3 return cylinder action

Back action and mold cylinder return cylinder cylinder synchronous, electromagnet YA02 power 1.5 s, material return cylinder connected to gas source, discharging rod; the electromagnet YA01 was 1.5 s, material return cylinder is communicated with the atmosphere, the pressure cylinder down when the discharging rod is pushed back the work piece.

6 Conclusion

The advantages of this equipment is used for double action button, realize the security protection for the operator; to detect whether a work piece is installed by photoelectric sensor device, to avoid equipment damage and accident work not installed head under pressure; the pressure signal is input to the PLC through the pressure sensor, using PLC and man-machine interface to monitor the production process, so as to realize the monitoring of the pin is pressed into the most pressing force in the process; the pressure sensor unit is adopted first in the country, instead of the pressure sensor unit cost of imported only 17% imported [6]. unit adopts mechanical part pressure The gas control, power consumption is only 20% by the hydraulic system, but also reduces the equipment pollution to the environment, reduces the noise of the equipment. The equipment has been manufacturing, installation, commissioning and put into use. Through the detection of the production site, monitoring at the same time to pin for pressing the pressing force to the maximum the pin, can discover the unqualified products, achieve the expected effect of the design. The equipment design and manufacture to improve the mechanical manufacturing industry especially plays an important role in automobile electric appliance industry production efficiency and product quality.
