The pneumatic means of the shaping silica gel piece of a kind of fly-cutting
Technical field
The present invention relates to a kind of pneumatic means, the pneumatic means of the shaping silica gel piece of a kind of fly-cutting, belongs to silica gel piece production technical field specifically.
Background technology
Because the sealing of silica gel piece is good, when the sealing experiment doing booster shell, usually select silica gel piece as the important seal member of performing leak test instrument.Need sealing position shape size different based on booster shell, need the shape of the silica gel piece done also inconsistent, so be unsuitable for batch production.
The method that current production silica gel piece uses is manual excision forming, and not only efficiency is low, and unsightly, yield rate is also undesirable for appearance, is badly in need of now the device of the excision forming that a kind of structure is simple, cost is low, efficiency is high, yield rate is high.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus provide the pneumatic means of the shaping silica gel piece of a kind of fly-cutting, can complete the fly-cutting shaping work of silica gel piece, reduce manually-operated spoilage, operating efficiency is high.
According to technical scheme provided by the invention, the pneumatic means of the shaping silica gel piece of a kind of fly-cutting comprises workbench, it is characterized in that: fixed support on workbench, pedestal upper end fixes cylinder.Cylinder lower end connects piston rod, and piston-rod lower end is threaded connection cutting knife, and cutting knife lower end connects cutting blade.Be provided with boss in described cutting knife, boss center is provided with boss hole.Boss upper end is provided with upper limit position block, and boss lower end is provided with lower position block.Lower position block is threaded with upper limit position block through boss hole.Lower position block lower end linking springs, lower spring end connects spring column.
Further, surface is provided with base on the table, and base is positioned at immediately below cutting blade.
Further, boss hole diameter is less than upper limit position block and lower position block diameter.
Further, cutting blade adopts high speed steel material to make.
Further, spring column adopts nylon material to make.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, ensure that product quality, improves operating efficiency, decreases manually-operated spoilage, and simple to operate, safe and reliable.

Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises workbench 9, fixed support 2 on workbench 9, and cylinder 1 is fixed in support 2 upper end.
Cylinder 1 lower end connects piston rod 3, and piston rod 3 lower end is threaded connection cutting knife 5, and cutting knife 5 lower end connects cutting blade 6.
Be provided with base 7 at workbench 9 upper surface, base 7 is positioned at immediately below cutting blade 6.
Be provided with boss 4 in described cutting knife 5, boss 4 center is provided with boss hole 13.Boss 4 upper end is provided with upper limit position block 9, and boss 4 lower end is provided with lower position block 10.Lower position block 10 is threaded with upper limit position block 9 through boss hole 13.Lower position block 10 lower end linking springs 11, spring 11 lower end connects spring column 12.
Described boss hole 13 diameter is less than upper limit position block 9 and lower position block 10 diameter.
Described cutting blade 6 adopts high speed steel material to make.
Described spring column 12 adopts nylon material to make.
Operation principle of the present invention is: during work, is placed on base by shaping silica gel piece to be cut.Start cylinder operation button, cylinder drives piston rod to move down cutting silica gel piece, and spring column pressurized Compress Spring shrinks.Lift when completing on excision forming work exhaust hood, spring column ejects and is ejected by the silica gel piece of machine-shaping, completes processing.Finished product required for replaceable different cutting cutter hub realizes.Structure of the present invention is simple, compact, reasonable, ensure that product quality, improves operating efficiency, decreases manually-operated spoilage, and simple to operate, safe and reliable.
