Technical scheme 1: the Wrapping formed equipment of a kind of large aperture framework plastic tube, it comprises production device of wall tube of large aperture framework-tube polyethylene winding structure, template I in the described production device of wall tube of large aperture framework-tube polyethylene winding structure, the template II, one of template III formation is just round, template I calibration 40 degree, template II calibration 155 degree, template III calibration 165 degree, pull bar one end adopts axle to be connected with swivel nut, the other end is connected with template by crank one end, the crank other end is connected with template by rotating shaft, rotating shaft cooperates with the swivel nut screw drives, rotating shaft rotation 30 circles, swivel nut moves 180mm, and the mould internal diameter shrinks 13mm.
Technical scheme 2: the release method of the Wrapping formed equipment of a kind of large aperture framework plastic tube, employing instrument rotating shaft, the trapezoidal thread of last 15 TR36 of place * 6 of axle of rotation, threads turn drives swivel nut, swivel nut is moved right, adopt axle to be connected between pull bar and the swivel nut, so drive pull bar and move right, pull bar drives the template II again and moves downward; After the template II moved downward 14mm, crank entered separated region around track shaft and the little mould rotational trajectory intersecting area of passing by, and then drives the template III by crank and moves downward, and this moment, the mould external diameter diminished the product demoulding smoothly.
The present invention compares with background technology, and one is that 15 screw threads drive simultaneously, and the screw rod load is disperseed, and screw rod is carried more than 5 times than like product; Two is that 15 strong points drive simultaneously, increases multi-point support for 7 meters moulds of length, makes mould circularity height, is out of shape little; The 3rd, the device fabrication required precision is low, overcomes single screw drive major axis, and strong point gap is little, and difficulty of processing is big.
