Description
Technical field
This technology relates to the PTFE tube material vertical extruder being prepared into tubing after PTFE powder pressurized, heated.
Background technology
Suspension injecting tetrafluoroethylene (PTFE) belongs to existing product, and this product has each hydrogen atom poly and is entirely the chemical constitution that fluorine atom replaces, and is the high polymer long chain structure that molecular weight reaches 200 ten thousand to 1,000 ten thousand.Because the fluorine atom in fluorocarbon polymer has very strong chemical binding force, so compare with other similar plastics, there are more superior heat resistance and resistance to chemical reagents.Fluorine atom contained in molecule is more, and this character is more remarkable.
Suspension injecting tetrafluoroethylene is used generally to need its compression molding.Compression molding is named compression molding again, and compression molding powdery or granular resin is added the metal die maintaining uniform temperature make it plastify, and be full of whole die cavity under the effect of the pressure, then namely obtains prefabrication through the pressurization demoulding.Prefabrication puts into sintering furnace again, and namely heat-agglomerating obtain product.Compression molding configuration press, mould and sintering furnace just can be produced, but production efficiency is not high, only applicable small lot batch manufacture.
Summary of the invention
The object of this technology is to provide and a kind of feeding, extruding, hot briquetting is formed one, PTFE tube material vertical extruder that production efficiency is high.
The PTFE tube material vertical extruder of this technology, it comprises the external mold 11 having centre bore, the core 12 that are fixed in frame; Core passes from the centre bore of external mold, forms die cavity 13 between core and external mold centre bore; Die cavity comprises the extruded segment 131 of epimere and the profiled section 132 of hypomere; The external mold periphery of profiled section part arranges the induction heater 14 heated external mold; The pressing mold 15 being slidably arranged in core periphery is provided with above die cavity, pressing mold and the main drive 16 driving pressing mold to slide along core up and down and pass in and out extruded segment are connected, periphery, external mold upper surface arranges back-up ring 129, forms the feed bin 17 for holding material between external mold upper surface and back-up ring inner circumferential; Bottom in feed bin is provided with material scraping plate 18; Material scraping plate rotates around core axis and the material in feed bin is sent into die cavity under the drive of scraper drive unit 19.
The beneficial effect of this technology: during use, feed bin put into by PTFE powder, and driven the rotation of material scraping plate by scraper drive unit, powder enters in die cavity, and then main drive drives pressing mold to move down, and material in die cavity is pressed down; After the minimum point that pressing mold moves down, move up again and leave die cavity, then the material scraping plate rotated is scraped powder into die cavity again, pressing mold moves down again, so repeatedly, is extruded rear material and enters into profiled section from extruded segment gradually, lower the temperature gradually again after profiled section is heated to form molten state, then shaping, from profiled section out, complete the preparation of tubing.The rotation of material scraping plate, can also ensure that material in feed bin is in the circumferential direction centered by core axis, material thickness is basically identical, thus ensures the material uniformity in circumferential direction that enters in die cavity.The feeding of this equipment collection, extruding, hot briquetting forms one, production efficiency is high.
Above-mentioned PTFE tube material vertical extruder, the structure that material scraping plate is connected with scraper drive unit 19 is: arrange the gear wheel 110 be arranged in frame rotated around mandrel axis in the periphery of back-up ring, the pinion 111 engaged with gear wheel is arranged on the output shaft of scraper drive unit; Material scraping plate 18 is connected with gear wheel by the connecting plate 112 striden across above back-up ring.
Above-mentioned PTFE tube material vertical extruder, the conical surface 113 low centered by the bottom of feed bin, periphery is high.Like this, powder is from easily entering the die cavity being positioned at center.
Above-mentioned PTFE tube material vertical extruder, the structure that pressing mold and main drive 16 is connected is: in frame, at least arrange two guide pillars 114 parallel with mandrel, what sleiding form 115 slided arranges on guide pillar, and sleiding form is connected with pressing mold with main drive simultaneously.The guide pillar led to the slip of sleiding form 115 is set, ensure that pressing mold moves along core axis.
Above-mentioned PTFE tube material vertical extruder, has respectively in the top and the bottom of sleiding form 115 and is arranged on cope match-plate pattern 116 on guide pillar and lower bolster 117; Main drive is master cylinder, and the Master cylinder body 161 of master cylinder is arranged on cope match-plate pattern; The main piston rod 162 of master cylinder is connected with sleiding form 115; Core is upward through hollow main piston rod and is connected with Master cylinder body; External mold is connected on lower bolster.Sleiding form 115, cope match-plate pattern 116 and lower bolster 117 are co-located on column, easily ensure the axiality of external mold, core rod, and adopt master cylinder as main drive, pressure is large simultaneously, and core rod is through hollow main piston rod, and complete machine structure is simple.
Above-mentioned PTFE tube material vertical extruder, external mold is connected to the structure on lower bolster: be provided with on lower bolster under having endoporus and connect dish 118, and be connected in endoporus positioning sleeve 120; External mold upper end is connected with flange 119 by screw thread pair; Flange 119 with under connect dish lower surface be connected; Positioning sleeve 120 lower end and the groove fit opened in external mold upper surface; Positioning sleeve has the axis hole equal with center hole size; Mandrel also and axis hole forms cavity 133 through the axis hole on positioning sleeve; Described cavity docks with extruded segment 131.This structure, positioning sleeve can regard a part for external mold as, and cavity 133 also can regard a part for extruded segment as.By positioning sleeve, radial location is carried out to external mold, simultaneously positioning sleeve with under connect and coil inner hole and be connected and carry out radial location, be more prone to the axiality of guarantee external mold and core.
Above-mentioned PTFE tube material vertical extruder, the structure that sleiding form is connected with pressing mold is: pressing mold is fixed on tie-plate 126, tie-plate 126 and positioning disk 127 are located in radial fit and are connected with positioning disk, and positioning disk 127 is located in radial to coordinate with sleiding form and connects with sleiding form.The structure that this structure is located pressing mold, easily ensures the axiality of pressing mold and core.
Above-mentioned PTFE tube material vertical extruder, positioning sleeve upper end protrudes from down and connects dish, arranges cooler pan 121 at positioning sleeve upper periphery, and the periphery of cooler pan fixes described back-up ring; Described feed bin 17 is formed between the upper surface of cooler pan, the upper surface of positioning sleeve, back-up ring inner circumferential; Have the cooling chamber 1211 passing to cooling water in cooler pan, cooling chamber communicates with water inlet pipe 1212, outlet pipe 1213 respectively; The lower end of cooler pan 121 with under connect dish upper surface contact; What under being positioned at, connect dish periphery is connected with refrigerating seat 122 on lower bolster lower surface, has the water cavity 1221 passing to cooling water in refrigerating seat.Because material in extruded segment is squeezed compression, the temperature of extruded segment is higher, adopts the cooler pan passing to cooling water to carry out cooling down to positioning sleeve, ensure that the reliably working of positioning sleeve.Meanwhile, cooler pan and back-up ring, positioning sleeve form feed bin jointly, and structure is simpler.Cooler pan also can under connect dish and cool.
Above-mentioned PTFE tube material vertical extruder, the joint of the upper surface of axis hole and positioning sleeve is fillet.Fillet makes material more easily slip into die cavity.
