Description
Technical field
The present invention relates to technical field of pressing machine, more particularly to a kind of polytetrafluoroethylene (PTFE) press.
Background technology
Polytetrafluoroethylene (PTFE) (Teflon or PTFE), is commonly called as " King ", is by the aggregated macromolecule of tetrafluoroethene
Compound, with excellent chemical stability, corrosion resistance, sealing, high lubrication non-stick, electrical insulating property and well anti-ageing
Change endurance.As engineering plastics, polyfluortetraethylene pipe, rod, band, plate, film etc. can be made into.Press be forcing press, hydraulic press,
The abbreviation of hydraulic press, press refers to a kind of forming machine by pressure forming for industrial product, typically using hydraulic jack, because
This is also hydraulic press.Now need it is a kind of can be by the machine of pressure forming polytetrafluoroethylene (PTFE).
The content of the invention
To the above-mentioned state of the art, the technical problems to be solved by the invention are to provide a kind of reasonable in design gather
Tetrafluoroethene press.
The present invention solve the technical scheme that is used of above-mentioned technical problem for：A kind of polytetrafluoroethylene (PTFE) press, including support,
Upper cylinder half is provided with above the support, lower section is provided with lower cylinder, and centre is provided with below formation cylinder, the upper cylinder half and is provided with float plate, described
Through there is upper plunger in the middle of float plate, the upper plunger is offseted with the upper cylinder half, and polyurethane power transmission film is provided with the formation cylinder, is gathered
Fixed plate is provided with below urethane mould, the formation cylinder.
Further, the frame bottom is provided with base plate, and the lower cylinder, which is put, to be fixed on the base plate, for fixed shaping
Cylinder and its internal polyurethane power transmission film, polyurethane mould.
Further, running through in the middle of the fixed plate has fixing bolt.
Further, through there is connecting rod in the float plate, the connecting rod lower end is extended downward into fixed plate.
Compared with prior art, the advantage of the invention is that：The present invention is used to produce tubulose bar, can produce hollow, blind
Hole, water route etc., the relatively conventional isostatic pressing machine of the present invention compares the contact avoided with oil, and production efficiency, which is improved, avoids pollution,
The length and die debugging of product can be preferably controlled compared with rotary dry bag press, the present invention is reasonable in design, can advise greatly
Mould is promoted.
Brief description of the drawings
Fig. 1 is a kind of polytetrafluoroethylene (PTFE) press structure schematic diagram of the invention.
Embodiment
In order to make the purpose , technical scheme and advantage of the present invention be clearer, below in conjunction with accompanying drawing, the present invention is entered
Row is further described.
As shown in figure, a kind of polytetrafluoroethylene (PTFE) press, including support 1, the top of support 1 is provided with upper cylinder half 2, and lower section is set
There is lower cylinder 3, middle to be provided with formation cylinder 4, the lower section of upper cylinder half 2, which is provided with to run through in the middle of float plate 5, the float plate 5, upper plunger
6, the upper plunger 6 offsets with the upper cylinder half 2, is provided with polyurethane power transmission film 7, polyurethane mould 8 in the formation cylinder 4, it is described into
The lower section of shape cylinder 4 is provided with fixed plate 9, and the bottom of support 1 is provided with base plate 10, and the lower cylinder 3, which is put, to be fixed on the base plate 10, uses
Running through in the middle of fixed formation cylinder 4 and its internal polyurethane power transmission film 7, polyurethane mould 8, the fixed plate 9 has fixed spiral shell
Through there is connecting rod 12 in bolt 11, the float plate 5, the lower end of connecting rod 12 is extended downward into fixed plate 9.
Operation principle is briefly explained：
Upper cylinder half loads onto punching for preform and the control cylinder of product length.
Formation cylinder-high-pressure forming, upper and lower side has exhaust outlet and oil inlet respectively.
Lower cylinder --- ejection and product length adjustment for product.
Compared with prior art, the advantage of the invention is that：The present invention is used to produce tubulose bar, can produce hollow, blind
Hole, water route etc., the relatively conventional isostatic pressing machine of the present invention compares the contact avoided with oil, and production efficiency, which is improved, avoids pollution,
The length and die debugging of product can be preferably controlled compared with rotary dry bag press, the present invention is reasonable in design, can advise greatly
Mould is promoted.
