Abstract
The invention discloses an extruded plastic tube inflatable aired up device. The device comprises a steel frame and a round rubber plate, wherein the steel frame is provided with airbag fixing rings and airbags; the steel frame has a round disc structure, the outer edge part of the steel frame has an enlarged radius and projects to have a semi-rim shape, the bottom center of the steel frame is welded to one round steel tube, and the top of the round steel tube is welded with a hanger; the airbag fixing rings are positioned behind the inner sides of the airbags, the airbag fixing rings and the airbags are wound into one through heat insulation woven belts in a two-layer manner and then are fixed to the outer ring of the steel frame, and each of the steel frame and the airbag fixing rings is provided with a valve port; and the bottom of the steel frame is provided with the round rubber plate, and the round rubber plate is tightly compressed on the steel frame by press rings, and then is fixed by bolts. The device has the advantages of simple and unique structure, adjustable pressure of air inflated into the airbags, tight air sealing, convenient maintenance, light weight, convenient installation, and practical production operation benefiting.
Description
Affiliated technical field:
The present invention and a kind of gas block apparatus say that more specifically a kind of extruding mould pipe inflatable gas block apparatus.
Background technology:
The gas block apparatus is used for extruding moulding the pipe production industry, current China produces platen press in most employing of the outer pillar of high density polyethylene (HDPE) insulation, usefulness gas block apparatus seals tube wall during production, then being filled with compressed air in the tubing of extruding continuously holds round tube wall, until the tubing manufacturing is finished in tubing water-cooled setting in calibration sleeve.
To be two a pair of steel skeletons of usefulness with the thick cystosepiment of 30-40mm and the thick rubber slab of 15-20mm be clipped in the middle existing gas block apparatus fixedly makes, not only heavy but also installation is very difficult in use.
Summary of the invention:
In order to solve problems of the prior art, the invention provides the inflatable gas block apparatus that a kind of structure is unique, lightweight, be convenient to install.
Technical scheme of the present invention is: a kind of inflatable gas block apparatus, comprise steel skeleton and round rubber plate, and be provided with air bag retainer plate and air bag on the described steel skeleton; Described steel skeleton is circular tray type structure, the wheel rim shape is protruded in the outer part radius expansion of steel skeleton half, the bottom centre of steel skeleton and a round steel pipe welding, the welded top hangers of round steel pipe, the maximum gauge of steel skeleton is less than pipe internal diameter 100-140mm; Described air bag retainer plate internal diameter greater than steel skeleton at the bottom of the footpath 2-4mm, the air bag retainer plate is placed the interior rear flank of air bag, with heat insulation strap air bag retainer plate and air bag are wound in and are integrated, twine the outer ring that is placed on steel skeleton more than two-layer and fix, be equipped with valve port on described steel skeleton and the air bag retainer plate; The bottom of described steel skeleton is provided with the round rubber plate, by trim ring the round rubber plate is pressed on the steel skeleton and is fixed with bolt afterwards.
According to above technical scheme, described air bag is to form with car inner tube of a tyre bonding.Described heat insulation strap is glass fiber strap or woven belt.
The present invention's advantage compared with prior art is: 1, uniqueness simple in structure, and the air bag internal gas pressure is adjustable, and envelope gas is tight, easy to maintenance; 2, lightweight, easy for installation, be beneficial to the actual production operation.
Description of drawings:
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation that envelope gas stops up in the prior art.
Among the figure: 1, steel skeleton, 2, the air bag retainer plate, 3, heat insulation strap, 4, air bag, 5, rubber slab, 6, trim ring, 7, valve port.
The specific embodiment:
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:
Referring to Fig. 1, a kind of inflatable gas block apparatus, by steel skeleton (1), round rubber plate (5), air bag retainer plate (2) and air bag (4) consist of, described steel skeleton (1) is circular tray type structure, the outer part radius expansion of steel skeleton (1) is protruded into half wheel rim form in order to fixation balloon (4), the bottom centre of steel skeleton (1) and a round steel pipe welding, the welded top hangers of round steel pipe, steel skeleton (1) can be according to the pipe internal diameter of producing, make with the 6-10mm steel plate, its maximum gauge is less than pipe internal diameter 100-140mm, and valve port (7) is arranged at steel skeleton (1) bottom.Bonding the forming of the available motorcycle tyre tube of described air bag (4), described air bag retainer plate (2) is made with 30 * 4 band steels, and internal diameter has valve port (7) greater than footpath, steel skeleton (1) end 2-4mm.The inboard of air bag (4) will air bag retainer plate (2) be placed after the suitable inflation of air bag (4) again, with heat insulation strap (3) air bag retainer plate (2) and air bag (4) are wound in and are integrated, twine the outer ring that is placed on steel skeleton (1) more than two-layer and fix.The bottom of described steel skeleton (1) is provided with round rubber plate (5), rubber slab (5) is that 10-20mm is thick, its diameter is pressed on steel skeleton (1) by trim ring (6) with round rubber plate (5) and is upward fixed with bolt afterwards greater than pipe internal diameter 100-140mm.
The actual use when installing tangles hangers and the mould at round steel pipe top with stay cord or pull bar, bleed off the gas of air bag, is filled with an amount of gas behind the installation in position and gets final product.There is the deflation phenomenon to inflate at any time as finding in the production.
The above only is preferred embodiment of the present invention, is not structure of the present invention is done any pro forma restriction.Any simple modification that every foundation technical spirit of the present invention is done above embodiment, equivalent variations and modification all still belong in the scope of technical scheme of the present invention.
