Description
Technical field
The utility model relates to a kind of single apical cap multi-cylinder air cushion, belongs to press technologies field.
Background technique
In press machine, apical cap, in movement process, in order to meet pressure requirement, needs larger liftout power sometimes, and known F=PS, increase F, need to strengthen P or S.
According to the above description, as increased P, the force environment of the each portion of air cushion is comparatively severe, need to select good material just can bear, and causes manufacture cost high, does not meet economic benefit.
As increase S, make air cushion diameter increase, make air cushion structure not compact, take up room large, cause difficulty to installation.
In sum, how, in the situation that increasing F, how cleverly S to be increased, make again structure seem less too fat to move, just become a problem that needs solve.
Model utility content
The utility model is for above-mentioned defect, and object is to provide a kind of compact structure, and can meets single apical cap multi-cylinder air cushion of air cushion user demand.
The technical solution adopted in the utility model is for this reason: the utility model comprises cylinder body (1) and is arranged on cylinder body (1) outside and cylinder body (1) forms the apical cap (2) being sealed and matched, apical cap (2) upper inside surface covers cylinder body (1) upper surface, the source of the gas leading in cylinder body (1) moves upward apical cap (2) formation, described cylinder body (1) is made up of the chamber of multiple isolation, each chamber is all established piston (3), the ventilation source, bottom in piston (3) in chamber.
In described cylinder body (1), establish piston rod (4), on piston rod (4) is longitudinal, be connected respectively with the piston (3) in each chamber, piston rod (4) top is connected with apical cap (2).
In described cylinder body (1), be provided with the inner convex platform (5) of restriction each piston (3) movement travel.
Described cylinder (1) junction point interior and piston rod (4) is established the guide ring (6) of guide piston bar (4) motion.
Described each piston (3) top is provided with cushion pad (7), and cylinder body (1) upper surface is established cushion pad (7).
Described piston rod (4) is provided with through hole, and through hole and each chamber are communicated with.
Between described piston rod (4) and apical cap (2), between piston rod (4) and cylinder body (1), realize and connecting by pressing plate (8), clamping bolt.
Described cylinder body (1) is provided with hydraulic fluid port.
Described cylinder body (1) is made up of upper cylinder body (11) and lower cylinder body (12).
The utility model has the advantages that: 1) gas cylinder body adopts multi-cylinder structure, air inlet simultaneously, effectively like this increases air cushion liftout power, thereby can reduce the diameter of air cushion, facilitates the installation of air cushion;
2) the utility model is all equipped with a large amount of cushion pads at piston and cylinder body, cylinder body and apical cap contacting point, has reduced noise like this in the time that air cushion is worked, and has extended the working life of air cushion simultaneously;
3) the utility model, by the setting of inner convex platform, makes the movement travel of piston controlled, thereby reaches the object of controlling apical cap stroke;
4) the utility model arranges guide ring, and piston rod is realized to guiding, makes it smooth running.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
In figure, 1 is that cylinder body, 2 is that apical cap, 3 is that piston, 4 is that piston rod, 5 is that inner convex platform, 6 is that guide ring, 7 is that cushion pad, 8 is that pressing plate, 9 is suction port;
11 is that upper cylinder body, 12 is lower cylinder body.
Embodiment
The utility model comprises cylinder body 1 and is arranged on cylinder body 1 outside and cylinder body 1 forms the apical cap 2 being sealed and matched, apical cap 2 upper inside surface cover cylinder body 1 upper surface, the source of the gas leading in cylinder body 1 moves upward apical cap 2 formation, described cylinder body 1 is made up of the chamber of multiple isolation, each chamber is all established piston 3, and chamber is interior in ventilation source, the bottom of piston.
In described cylinder body 1, establish piston rod 4, on piston rod 4 is longitudinal, be connected respectively with the piston 3 in each chamber, piston rod 4 tops are connected with apical cap 2.
In described cylinder body 1, be provided with the inner convex platform 5 of each piston 3 movement travels of restriction.
In described cylinder 1, establish with the junction point of piston rod 4 guide ring 6 that guide piston bar 4 moves.
Described each piston 3 tops are provided with cushion pad 7, and cylinder body 1 upper surface is established cushion pad 7.
