Description
Technical field
This utility model be related to press machine auxiliary equipment and in particular to a kind of for the cam mechanism on press machine
Doffer.
Background technology
Punch press is a punching type forcing press, and punching production is primarily directed to sheet material, by mould can make blanking,
Punching, molding, drawing, finishing, fine, shaping, riveting etc. operate, and are widely used in mechanical processing industry, punch press pair during work
Sheet material press so as to plastic deformation and obtain required shape and precision, need to coordinate mould and lower mould on one group, by plate
Material is placed in therebetween, applies pressure by drift so as to deformation, can be attached to drift because drift applies sheet material after pressure to sheet material
Upper it is therefore desirable to by sheet material blanking good for punching press.
At present, the upper automatic blanking device of Production of Stamping Die processing is a lot, if by the way of nature blanking, to plate
The impact of material is big, and not only easy damaged sheet material causes the waste of material and the raising of cost, and stacking is irregular, staff
Need to be taken much time arrangement sheet material, makes work efficiency than relatively low；And certain peace is not only brought using artificial blanking to workman
Full hidden danger, and inefficiency；Also have on some punch presses and employ cylinder jet blanking, but can additionally consume certain energy
Source, improves production cost.At present, common metal material opens the automatic-blanking mechanism being used on flat machine although form is many
Sample, high working efficiency, but complex structure, complex operation, it is not easy to install and keeps in repair, and cost is also higher.
Content of the invention
This utility model provide a kind of for the cam mechanism doffer on press machine, this device can achieve sheet material from
Dynamic blanking, high working efficiency, structure is simple, easy to operate, is easy for installation and maintenance, energy-conserving and environment-protective, and low cost of manufacture.
For achieving the above object, a kind of for the cam mechanism doffer on press machine, including air valve and cam, institute
State air valve and cam be separately fixed in punch press bed body and the bent axle axle head of punch press on；Described air valve includes valve body and valve element, institute
The center stating valve body is hollow structure, hollow structure by top be used for storing the cylinder body cavity of compressed air, inverted round stage chamber and under
The cylinder body cavity composition in portion；Described valve element is included inverted round stage and is connected with inverted round stage cylindrical bar, the wall of described inverted round stage and rounding
The wall in platform chamber fits, and the wall of described cylindrical bar is fitted with the wall of cylinder body cavity；
Be cased with the nut for sealing hollow structure outside the top of described valve body, the center of nut be provided with air inlet and with
Hollow structure connects；The lower sides of described valve body are provided with the gas outlet with cylinder body cavity vertical connection, connect at gas outlet
There is gas blow pipe.
Further, it is provided with sealing gasket between described nut and the top of valve body.
Further, the middle part of described cylindrical bar is cased with sealing ring.
Compared with prior art, this utility model gyration is done by cam mechanism so that valve element valve body hollow
Pumping in structure, thus reaching the air inlet to valve body compressed air and aerofluxuss, and then completing to blow material blanking mistake
Journey；Utility model works efficiency high, structure is simple, easy to operate, is easy for installation and maintenance, energy-conserving and environment-protective, and manufacturing cost
Low, practical, it is suitable to be widely popularized use.

Specific embodiment
Below in conjunction with accompanying drawing, this utility model is described in further detail.
As shown in Figure 1 a kind of is for the cam mechanism doffer on press machine, including air valve and cam 8, described
Air valve and cam 8 be separately fixed in punch press bed body and bent axle 10 axle head of punch press on；Described air valve includes valve body 4 and valve element 6,
The center of described valve body 4 is hollow structure, hollow structure by top be used for storing the cylinder body cavity of compressed air, inverted round stage chamber and
The cylinder body cavity composition of bottom；Described valve element 6 includes inverted round stage and the cylindrical bar being connected with inverted round stage, the wall of described inverted round stage
Fit with the wall in inverted round stage chamber, the wall of described cylindrical bar is fitted with the wall of cylinder body cavity；The top of described valve body 4
Outside is cased with the nut 3 for sealing hollow structure, and the center of nut 3 is provided with air inlet 1 and is connected with hollow structure；Described valve
The lower sides of body 4 are provided with the gas outlet 5 with cylinder body cavity vertical connection, are connected with gas blow pipe at gas outlet 5.
In order that the sealing effectiveness in valve body 4 is more preferably, between described nut 3 and the top of valve body 4, it is provided with sealing gasket 2；Institute
The middle part stating cylindrical bar is cased with sealing ring 7.
During installation, cam 8 is fixed on bent axle 10 axle head of punch press, and bent axle 10 drives punch press ram 9 up and down reciprocatingly to transport doing
Dynamic；Air valve is fixed on bed body, draws gas blow pipe by gas outlet 5, is directed at mould.
During use, compressed air enters valve body 4 by air inlet 1, so that valve element 6 is obtained all the time in the presence of compressed air
One external force, makes the inverted round stage wall of valve element 6 be in close contact with the inverted round stage cavity wall face of valve body 4, thus reaching to compressed air
Sealing, sealing gasket 2 and sealing ring 7 play further sealing effectiveness to compressed air；When cam 8 makees gyration to necessarily
When angle is contacted with valve element 6, valve element 6 is promoted so that inverted round stage wall and the inverted round stage cavity wall face of valve body 4 is separated, compressed air is passed through
Gas outlet 5 is flowed out, thus completing to blow material process；When cam turns over certain angle and no longer has thrust to valve element 6, valve element 6 is in pressure
Recover sealing station in the presence of contracting air.
