Description
Technical field
The utility model relates to the punch press field, relates in particular to a kind of multistation gasbag-type top Lifting Device.
Background technology
The top Lifting Device has been widely used among all kinds of punch presses in recent years, when workpiece in punching course, separation is arrived in the upper and lower mould merging then, stamping forming product is attached on the mould, at this time just need come work by the top Lifting Device, the top Lifting Device of prior art comprises cylinder, push rod and ejector beam, when workpiece is shaping when finishing, can pass through to cylinder intake, the push rod that promotes then on the cylinder presses down ejector beam, ejector beam can press down product from mould, thereby realizes the function of liftout.It is limited that but prior art top Lifting Device takes up room because of cylinder, and the pressure size of liftout is relevant with cylinder size, so the liftout ability of prior art top Lifting Device is lower; And the push rod requirement on machining accuracy of prior art top Lifting Device is higher, processes the life-span that bad meeting directly influences the pad mould, has so not only improved processing cost, and has improved the difficulty of installing and keeping in repair; And because the air compression can produce water in the cylinder of the top Lifting Device of prior art, and the well draining of this structure of prior art.
Summary of the invention
Technical problem to be solved in the utility model is: provide that a kind of liftout ability is higher, processing more convenient and lower-cost multistation gasbag-type top Lifting Device.
The technical scheme that the utility model adopts is: a kind of multistation gasbag-type top Lifting Device, it comprises the gas receiver that is fixed on the punch press, die pad, many groups are fixed on and are used for the elastic device under the die pad top on the gas receiver and are arranged on a plurality of knockout rods on the die pad, described elastic device comprises the upper cylinder cover that is fixed on the gas receiver bottom, be fixed on the annular air-pocket on the upper cylinder cover and be fixed on following cylinder cap on the annular air-pocket, described upper cylinder cover, annular air-pocket and following cylinder cap form a closed cavity, and described upper cylinder cover is communicated with gas receiver, and described gas receiver is provided with a plurality of for the gas port to the gas receiver ventilation.
Adopt above structure compared with prior art, the utlity model has following advantage: the structure by annular air-pocket replaces original air cylinder structure, so not only take up room less and the liftout ability also bigger, can increase the liftout ability of Lifting Device greatly, and replace cylinder by air bag, make manufacturing cost also reduce; And removed push rod, processing cost is lower and installation and maintenance are more convenient like this, and when using, can not influence the life-span of pad mould.
As preferably, described cylinder cap down is provided with the osculum for draining.At following cylinder cap an osculum is set, the water that the air compression produces in the annular air-pocket can well be discharged like this, can not be trapped in down on the cylinder cap, thereby keep the interior cleaning of annular air-pocket.
As preferably, described osculum be provided with can switch lid.When not needing draining, can close upper cover like this, air is revealed from osculum in the time of can placing ventilation like this.
As preferably, described die pad one side is provided with the guide bush for guiding.By the effect that guide bush replaces original piston to lead, so not only can play good guide effect, and processing is simple, easy for installation.
Description of drawings
Fig. 1 is the cutaway view of the utility model multistation gasbag-type top Lifting Device.
As shown in the figure: 1, gas receiver; 2, die pad; 3, ejector beam; 4, upper cylinder cover; 5, annular air-pocket; 6, following cylinder cap; 7, gas port; 8, osculum; 9, guide bush.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment the utility model is described further, but the utility model is not limited only to the following specific embodiment.
As shown in the figure: a kind of multistation gasbag-type top Lifting Device, it comprises the gas receiver 1 that is fixed on the punch press, die pad 2, many groups are fixed on and are used for the elastic device under die pad 2 tops on the gas receiver 1 and are arranged on a plurality of ejector beams 3 on the die pad 2, described elastic device comprises the upper cylinder cover 4 that is fixed on gas receiver 1 bottom, be fixed on the annular air-pocket 5 on the upper cylinder cover 4 and be fixed on following cylinder cap 6 on the annular air-pocket 5, described upper cylinder cover 4, annular air-pocket 5 and following cylinder cap 6 form a closed cavity, and described upper cylinder cover 4 is communicated with gas receiver 1, and described gas receiver 1 is provided with a plurality of for the gas port 7 of giving gas receiver 1 ventilation.Described annular air-pocket 5 is by the ring-shaped rubber of a plurality of sealings and the annular steel ring that a plurality of ring-shaped rubbers combine is formed.
Described cylinder cap 6 down is provided with the osculum 8 for draining.
Described osculum 8 be provided with can switch lid.
Described die pad 2 one sides are provided with the guide bush 9 for guiding.
Operation principle of the present utility model is: a plurality of gas ports 7 that at first use air feed equipment to pass through on the gas receiver 1 are given gas receiver 1 air feed, air in the gas receiver 1 can enter into by the upper cylinder cover 4 that is communicated with gas receiver 1 in the annular air-pocket 5 then, because continuing ventilation, air pressure is higher, so annular air-pocket 5 can be strutted at vertical direction, again because gas receiver 1 is fixed on the punch press, be that annular air-pocket 5 can not move up, it just can only move down like this, be that annular air-pocket 5 can jack down die pad 2, reach the purpose that product is pressed down from mould; No longer continue ventilation then, when soon the air pressure in the gas receiver 1 dropped to normal level, the air pressure in the annular air-pocket 5 also can be got back to normal level, and namely annular air-pocket 5 also can be got back to normal height.
