Abstract
The utility model relates to an auxiliary sizing mold for a plastic corrugated pipe. The auxiliary sizing mold is characterized in that one end of a shaft 4 is in threaded connection with a hoisting ring screw 3, the shaft 4 penetrates through pressure plates 5, sealing discs 6 and adjustable plates and is fastened through a nut 8, and one adjustable plate 7 is arranged between the two adjacent sealing discs 6. The pressure plates 5 and the adjustable plates 7 are made of an aluminium alloy or a titanium alloy or a magnesium alloy. Each sealing disc 6 is made of a rubber plate. The external diameter of each sealing disc is in interference fit with the inner diameter of a single-wall corrugated pipe 9. The thickness of each adjustable plate 7 is not equal to the integral multiple of the corrugation distance of the single-wall corrugated pipe 9. The sizing mold is located in the inner wall of the corrugated pipe and is kept away from a nose of an extruder by a certain distance; and the mold is located in back of a tubular product hauling machine and in front of a tubular product slitting saw to form an inner high-pressure region, so that the pressure action region of the inner wall of the pipe is greatly enlarged, tubular products are well molded, and the wall thickness is relatively uniform.
Description
Technical field
The utility model relates to a kind of shaper, relates in particular to and presses auxiliary shaper in a kind of plastic film capicitor.
Background technology
Country more and more payes attention to Green Sustainable in recent years, and people begin also to notice that the activity in production of self is on the impact of natural environment.Bellows has progressively replaced the less demanding pipe of cement of working environment as a kind of novel environment friendly tubing, some highly energy-consumings such as steel pipe, and the tubing of high pollution, and also its intensity is high, and good toughness has been applied to more and more widely industry field now.
Along with the popularization and application of bellows, people are to the Forming Quality of bellows, and the aspects such as service life require also more and more higher.Common single-wall corrugated pipe molding mode is the unshaped materials in the tube that extruder is extruded, pressure-acting by gases at high pressure, the mould of materials in the tube and back forming machine is fitted, again by the cooling forming of forming machine, allow single-wall corrugated pipe reach the tubing waveform of expection.This old molding mode is difficult to adapt to the requirement of bellows high-speed molding, and because the high-pressure gas pressure that passes into is unstable, the corrugated pipe wall thickness ununiformity of shaping pipe is even, and pipe workpiece quality can not be guaranteed.
The utility model content
The technical problem that the utility model solves is to overcome the deficiencies in the prior art, provides a kind of high-pressure gas pressure that passes into that makes stable, and the plastic film capicitor of bellows wall thickness uniform in shaping is assisted shaper.
The technical solution adopted in the utility model is the auxiliary shaper of a kind of plastic film capicitor.Axle one end of mould is threaded with lifting bolt, and axle passes platen, seal disc and adjustment plate, and by fastening nuts, be provided with adjustment plate between two adjacent seal discs.
The material of platen and adjustment plate is aluminium alloy or titanium alloy or magnesium alloy.The material of seal disc is rubber slab.Select the mould of these materials to reduce weight, avoid mould structure heavy, cause to the compressive deformation of bellows or to tube wall and produce cut.
The thickness of adjustment plate is not equal to the integral multiple of single-wall corrugated pipe ripple spacing, and seal disc contacts with the tube wall internal diameter always, to prevent that seal disc drops in the bellows fully on the mould.
The internal diameter interference fit of the external diameter of seal disc and single-wall corrugated pipe forms the sealed high pressure district like this in the profiled section, make the better moulding of bellows, and wall thickness is even.But will guarantee that also interference fit does not affect mould to the sliding motion of bellows, this Interference size is different according to different products.
The beneficial effects of the utility model are inwalls that mould is arranged in bellows, be connected with the cross-head suspension ring by pull bar, maintain a certain distance with cross-head, mould is positioned at after the pipe tractor, before the tubing cast-cutting saw, increased so greatly inside pipe wall pressure-acting zone, make tube forming more perfect, the distance of the pressure of the gas effect of inside and pressure-acting profiled section when coming the control valve material forming with this mould, quality influence when considering simultaneously this mould to tube forming, therefore this mould is placed into position behind the tubing cooling and shaping, can effectively avoids like this this mould on the impact of unshaped tubing.
Description of drawings
Fig. 1 is the structural representation of the auxiliary shaper of plastic film capicitor of the present utility model;
Structural representation when Fig. 2 is the auxiliary shaper work of plastic film capicitor of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2, a kind of plastic film capicitor is assisted shaper, and axle 4 one ends are threaded with lifting bolt 3, and axle 4 passes platen 5, seal disc 6 and adjustment plate 7, and fastening by nut 8, be provided with adjustment plate 7 between two adjacent seal discs 6.
The material of platen 5 and adjustment plate 7 is aluminium alloy or titanium alloy or magnesium alloy.The material of seal disc 6 is rubber slab.Select the mould of these materials to reduce weight, avoid mould structure heavy, cause to the compressive deformation of bellows or to tube wall and produce cut.
The internal diameter interference fit of the external diameter of seal disc 6 and single-wall corrugated pipe 9.Form like this sealed high pressure district in the profiled section, make the better moulding of bellows, wall thickness is even.But will guarantee that also interference fit does not affect mould to the sliding motion of bellows, this Interference size is different according to different products.
The thickness of adjustment plate 7 is not equal to the integral multiple of single-wall corrugated pipe 9 ripple spacings, and seal disc 6 contacts with the tube wall internal diameter always, to prevent that seal disc drops in the bellows fully on the mould.
Mould is arranged in the inwall of bellows, be connected with cross-head suspension ring 1 by pull bar 2, cross-head maintains a certain distance, mould is positioned at after the pipe tractor, before the tubing cast-cutting saw, formed in one in tubing inside like this and pressed the higher-pressure region, increased greatly inside pipe wall pressure-acting zone, make tube forming more perfect, the distance of the pressure of the gas effect of inside and pressure-acting profiled section when coming the control valve material forming with this mould, therefore quality influence when considering simultaneously this mould to tube forming is placed into position behind the tubing cooling and shaping to this mould, can effectively avoid like this this mould on the impact of unshaped tubing.
It should be noted that at last: although abovely described the specific embodiment of the present utility model; but those skilled in the art are to be understood that; these only illustrate; can make various changes or modifications to these specific embodiment; and not deviating from principle of the present utility model and essence, protection domain of the present utility model is defined by the claims.
