Description
Technical field
The present invention relates to a kind of processing unit (plant), specifically a kind of processing unit (plant) of polytetrafluoroethylene (PTFE) part.
Background technology
Polytetrafluoroethylene (PTFE) is claimed " King ", and it is to work as this life to have excellent chemical stability, antiacid alkali resistant, corrosion resistance
One of decay resistance optimal material in boundary, meanwhile, polytetrafluoroethylene (PTFE) has resistant to elevated temperatures feature, and its coefficient of friction is extremely low,
So after can making lubrication, its generation solves many problems in the fields such as chemical industry, oil, pharmacy, at present, for poly-
It is typically to be molded using shaping equipment for tetrafluoroethene product, although existing former can be efficiently complete
Into the making of product, but its equipment is huger, and technological process is cumbersome, not only occupies larger space, wastes equipment
Cost and production cost is also very high, for some small parts, one kind is undoubtedly using existing this equipment
Waste.
The content of the invention
The technical problem to be solved in the present invention is to provide it is a kind of it is simple in construction, occupy little space, easy to use and shaping matter
The processing unit (plant) of measured polytetrafluoroethylene (PTFE) part.
In order to solve the above-mentioned technical problem, the processing unit (plant) of polytetrafluoroethylene (PTFE) part of the invention, including upper bolster and lower mould
Seat and the guide pillar between upper bolster and die shoe, the middle part of die shoe have the lower mould being fixedly mounted in die shoe
Body, upper die body is mounted with above lower mold body, die cavity is formed between die body and lower mold body, the bottom of upper bolster is provided with guiding
Plate, guide plate connect lower platen by being cased with the guide rod of spring, and the top of upper bolster is additionally provided with through guide plate and pushed
The hydraulic stem at plate center, the lower end of hydraulic stem are provided with briquetting, and lower platen can make briquetting to upper die body after compressing upper die body
Center top pressure.
The top of the upper die body is provided with conical surface annular groove, and the briquetting is arranged to the frustum knot coordinated with conical surface annular groove
Structure, the briquetting can be pressed in conical surface annular groove.
The passage for leading to die cavity is provided with the lower mold body.
Heating tube of the ring cloth around lower mold body is provided with the die shoe.
After above-mentioned structure, the lower platen of installation is oriented to, through leading by guide plate due to setting on upper bolster
The lower mold body installed to the center of plate, the hydraulic stem at lower platen center and die shoe, it is possible thereby to directly pass through lower platen pair
Upper and lower die body is compacted, at the same time by the briquetting on hydraulic stem to upper die body central pressing, polytetrafluoroethylene (PTFE) part into
Force compound that there is identical pressure in the surrounding of die cavity during type, which thereby enhance Forming Quality, the letter of its structure design
It is single, occupy little space, using very convenient and substantially increase Forming Quality.
