| Hydraulic and pneumatic supercharging cylinder type and the common control | Hydraulic and pneumatic supercharging cylinder
In stamping forming process is introduced the selection of gas and liquid pressurization cylinder
Gas-liquid pressurized cylinder type method:
According to the shape of workpiece can determine the shape of the trip, generally required turbocharged 5mm manufacturer USES 10mm, 15mm, four kinds of specifications and 20mm.
According to the loading and unloading a space can determine the headquarters, general manufacturer required by 50, and 200mm 100mm 150mm, four specifications.
According to the forming of blunt pressure, the existing air pressure can determine the maximum output pressure required
According to the maximum output pressure gas and liquid pressurization can determine diameter cylinder, hydraulic and pneumatic supercharging with output diameter cylinder pressure contrast
Pneumatic control principle
Manual control principle chart will put down the workpiece, hands plucked the valve, the valve inlet 6 August, punch 2 fast approaching. Hands plucked the valve, the valve inlet 5 July 2 stamping workpiece, punch shape. Hand in July, the first strike valve disc, punch 8 strike quickly returned two. Due to the use of the components, low cost, and less work, need not pure air power, so that the other is tooling or equipment at the beginning of the commissioning of the first control scheme. In formal when using, sometimes in order to increase the production efficiency, and will take a free hand and then can be replaced manual directional valve pedal switch.
With external control circuit of the pneumatic control system will put down the workpiece, valve, the valve 6 August 2 fast approaching, punch intake. 2 after exposure to punch, hydraulic and pneumatic supercharging workpiece in cylinder pressure, the pressure switch, July 11 action, valves and valve inlet, stamping workpiece. I. 2 Time-lapse 5s after 7 and 8 valve, the valve respectively, 3, punch 2 quick return air intake. The scheme requires electric control cabinet, still can match with the manipulator handling a line, the automation. Compared with the pure manual system cost is higher, but a high degree of automation, safe operation, so the scheme in automation to demand higher occasions wide application. |
