Abstract
The utility model discloses a combined thermal insulation connecting washer, which is an annular washer provided with different internal diameters at the upper and the lower parts thereof and made of thermal insulation materials, wherein the upper part of the thermal insulation connecting washer is changed to be a steel plate ring, and the lower part thereof is still the thermal insulation material washer; the steel plate ring and the thermal insulation material washer are fixedly riveted into a whole through a rivet; and the internal diameter of the steel plate ring and the external diameter of a PTFE plate ring serve as connecting stop openings. Compared with the prior art, the combined thermal insulation connecting washer has the advantage that as the steel plate ring and the PTFE plate ring are riveted into a whole, the PTFE steel plate is prevented from being deformed; and the combined thermal insulation connecting washer is solid and durable and has long service life.
Description
Affiliated technical field:
The utility model relates to a kind of heat insulating washer, the combined heat insulated connection packing ring of saying so more specifically.
Background technique:
Heat insulation connection packing ring is used in to extrude moulds the pipe production industry, and current China produces platen press in most employing of the outer pillar of high density polyethylene (HDPE) insulation; Seal the mouth of pipe during production, charge into pressurized air in the tubing of extruding continuously, pipe adds cooling jacket, makes pipe outer surface be attached to cooling shaping in the water jacket, finishes the method that tubing is made.Thermal insulating pad is used for interior platen press production process, it is installed between the cooling jacket (below 40 ℃) of the mould (more than 200 ℃) of high temperature and low temperature, prevent hot and cold mutual conduction, art methods is that the poly-tetrafluoro plate with the 16-20 millimeters thick directly is processed into the thermal insulating pad (see figure 2), owing to the bigger reason of the two sides temperature difference, after each the use, the bore 0.1-0.5 millimeter that can diminish of pad, particularly bigbore pad is particularly serious more than 1 meter, need repair when reusing and mould seam fit dimension, generally use 1-2 just to scrap because of repairing.Because poly-tetrafluoro plate price is very high, annual input cost is bigger.
Summary of the invention:
In order to solve problems of the prior art, the utility model provide a kind of can be because of the bigger and varying sized combined heat insulated connection packing ring of the temperature difference.
The technical solution of the utility model is: a kind of combined heat insulated connection packing ring, it is the ring washer that differs by the top and the bottom internal diameter that thermal-protective material is made, the top of described heat insulation connection packing ring changes into uses the steel plate circle, the thermal-protective material packing ring is still used in the bottom, described steel plate circle fixedly makes it become as a whole with the thermal-protective material packing ring with closing-up, with steel plate circle internal diameter, poly-tetrafluoro plate circle external diameter as connecting seam.
According to above technological scheme, described thermal-protective material is poly-tetrafluoro plate.The crown of described rivet is lower than thermal-protective material packing ring 2-3 millimeter, rivet pitch 50-70 millimeter.
The utility model compared with prior art has following advantage: 1. the steel plate circle becomes the as a whole distortion of having prevented poly-tetrafluoro plate circle with poly-tetrafluoro plate circle riveted.2. sturdy and durable, long service life.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a heat insulating washer of the prior art.
Among the figure: 1, steel plate circle, 2, rivet, 3, the thermal-protective material packing ring.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
Referring to Fig. 1, a kind of combined heat insulated connection packing ring, it is the ring washer that differs by the top and the bottom internal diameter that thermal-protective material is made, it is characterized in that, the top of described heat insulation connection packing ring changes into uses steel plate circle (1), thermal-protective material packing ring (2) is still used in the bottom, steel plate circle (1) and the thickness that with thickness is the 6-10 millimeter is that the thermal-protective material packing ring (2) of 8-12 millimeter fixedly makes it become as a whole with rivet (3) riveted, the crown of described rivet (3) is lower than thermal-protective material packing ring (2) 2-3 millimeter, rivet (3) spacing 50-70 millimeter, the mould seam of during use pipe being moulded in steel plate circle (1) internal diameter and production cooperates, thermal-protective material packing ring (2) external diameter cooperates with the cooling jacket seam, tightens the connection of the flange between mould and the cooling jacket fixing then.
The above only is the utility model preferred embodiment, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model is to any simple modification that above embodiment did, and equivalent variations and modification all still belong in the scope of the technical solution of the utility model.
Claims (3)
1. combined heat insulated connection packing ring, it is the ring washer that differs by the top and the bottom internal diameter that thermal-protective material is made, it is characterized in that, the top of described heat insulation connection packing ring changes into uses steel plate circle (1), thermal-protective material packing ring (2) is still used in the bottom, described steel plate circle (1) fixedly makes it become as a whole with thermal-protective material packing ring (2) with rivet (3) riveted, with steel plate circle (1) internal diameter, poly-tetrafluoro plate circle external diameter as connecting seam.
2. a kind of combined heat insulated connection packing ring according to claim 1 is characterized in that, described thermal-protective material packing ring (2) is made for poly-tetrafluoro plate.
3. a kind of combined heat insulated connection packing ring according to claim 1 is characterized in that the crown of described rivet (3) is lower than thermal-protective material packing ring (2) 2-3 millimeter, rivet (3) spacing 50-70 millimeter.
