Description
Technical field
The present invention relates to a kind of air intake structures, more particularly, to a kind of press machine Double-deck air cylinder air intake structure.
Background technique
Medium-and-large-sized mechanical press, which is generally required, stretches pad using pure gas formula, these mechanical press are equipped with stretching pad
Afterwards, so that it may expand the use scope of press machine.Stretching pad effect, mainly there are two aspects: being on the one hand the handle in drawing sequence
The edge of plate compresses, and workpiece is made to be unlikely to wrinkle occur in drawing process；It on the other hand, can be from lower die after sliding block backhaul
Workpiece is ejected, the material returned is used as.
When the small mechanical press of some sliding block table tops need to be equipped with larger ejecting force drawing pad when, installation space just by
To very big limitation.Pad will will be stretched in the case where meeting ejection force request and requirements of installation space is fabricated to two-layer equation.Two-layer equation
Stretching pad needs two cylinder air inlets simultaneously up and down to guarantee piston while move up and down.It is traditional in order to guarantee rapid air feeding
Intake method is that the air inlet of upper cylinder and lower cylinder is passed through three-way pipeline fittings.
But this admission line arrangement needs to have enough spaces between upper cylinder, lower cylinder and pedestal, if before pedestal
Left and right width direction does not have space afterwards, can only reserve upper cylinder air inlet tube space, such pole by increasing pedestal whole height
Big increases lathe production cost and client's purchase cost；This admission line arrangement needs worker to match welding peace surely simultaneously
Dress, operation difficulty are larger.
