Description
Technical field
The device of ejection and its control method, more particularly to a kind of sliding block backhaul air cushion is delayed to delay the present invention relates to a kind of
The device and its control method of ejection.
Background technology
Currently, equipped with air cushion on forcing press, air cushion serves when carrying out deep-drawing technique draws side and inloading part；Air cushion into
Play head part when row punching process.In the prior art, when forcing press works, backform device is in inflated condition, and air cushion is in upper
Dead-centre position；When forcing press finishing drawing and punching process, air cushion is pressed onto down by sliding block from the bottom dead centre of top dead-centre movement
Dead-centre position, the gas in backform device just return in gas receiver；When sliding block backhaul, the gas in gas receiver enters backform device again
In, air cushion is ejected, realizes head part effect, therefore the ejection cycle of air cushion is synchronous with the return interval of sliding block.But certain
Technological requirement workpiece needs to carry out burr processing before ejection, since the ejection cycle of air cushion and the return interval of sliding block are synchronous,
Therefore it cannot be satisfied the technological requirement of processing burr.
Invention content
The object of the present invention is to provide devices and its control method that a kind of sliding block backhaul air cushion delays ejection, by that will push up
The air inlet of mold is connected with check valve one and two position three-way valve with gas receiver, the gas outlet check valve two and two of backform device
Triple valve is connected with gas receiver so that air cushion ejection cycle lags and sliding block return interval, ensure that time enough progress
Burr treatment process, and gas circulates between gas receiver and backform device always so that and gas can recycle, and ensure that
Pressure in gas receiver jacks up workpiece enough.
To achieve the above object, the present invention provides the device that a kind of sliding block backhaul air cushion delays ejection, including backform device,
Air cushion is provided in the backform device, the mandril of the air cushion stretches out the backform device and is connected with mold, the mold and cunning
Block matches, and the air inlet of the backform device is connected through check valve one with the delivery outlet one of two position three-way valve, the backform device
Gas outlet is connected through check valve two with the delivery outlet two of two position three-way valve, and the input port of two position three-way valve is connected with gas receiver.
When work, slide block down makes workpiece come downwards in mold, and workpiece makes mandril stress downlink with ejector pin contact, pushes up
Bar drives air cushion downlink, two position three-way valve work, delivery outlet one to close, and delivery outlet two is connected, and the gas in backform device is by external force
Gas receiver is drained by check valve two, air cushion comes downwards to backform device bottom, and workpiece is fallen into mold；Sliding block uplink, delivery outlet one
It remains turned-off, delivery outlet two is held on, and air cushion is continuously in backform device bottom, is processed to workpiece, when on sliding block
Behind row to vertex, delivery outlet one is held on, and delivery outlet two remains turned-off, and the gas in gas receiver is by delivery outlet one and unidirectionally
Valve one enters backform device, and air cushion stress drives mandril uplink so that workpiece uplink break away from moulds takes workpiece away.
