Abstract
The utility model relates to a drawing molding device for winding and molding on a spiral plastic pipe. The drawing molding device is particularly suitable for manufacturing the spiral plastic pipe with a large caliber and double walls. A shaping device for drawing and winding is composed of a planetary transmission roller, a front support disc, a back support disc, a middle support shaft, a press wheel, and a drive mechanism. The shaping device for drawing and winding is characterized in that a plastic section strip moves in an axial and a tangential modes on the planetary transmission roller and is continuously molded into the spiral pipe. The drawing molding device has the advantages of simple structure, easy manufacture and processing, and convenient operation and installation.
Description
The utility model relates to a kind of traction molding equipment of making plastic spiral pipe, is particularly suitable for the Wrapping formed manufacturing large-caliber double-wall of heterotypic strip plastic spiral pipe.
Make double-walled plastic pipe and generally adopt crawler type subdivision mould manufacturing method.The Germany He Gele bellows production and the special equipment Co., Ltd (HEGLER) that for example have international advanced technology, making double-walled plastic pipe adopts extruder to extrude the melting plastics, distribute outer wall and the level and smooth tube wall of internal layer by die head, the chain type mold rotation that the ectonexine flexible pipe enters subdivision mould traction formation system wherein, outer tube wall is through vacuumizing aftershaping for special-shaped, ripple, and inner layer tube wall is sticked together by contact pressure and outer tube hot melt, makes double-wall pipe through cooling, typing again.The size of the mouth mould of the die head that this manufacture method adopted and chain type revolution mould is all near size of pipe and tubing, when making heavy caliber pipe, die head and chain type revolution shaper and whole unit are all quite huge, manufacturing and installation accuracy to die head require high, and transmission system and control system are also very complicated, the equipment price costliness.Making internal diameter is that the above double-wall pipe of 200mm is just rather difficult, and the manufacturing internal diameter is the above double-wall pipe of 500mm even can not realizes.
The utility model proposes a kind of simple in structure being used to and make the novel traction former of plastic spiral pipe.
The pulling warp shaped device that the utility model proposes is made up of rack-mounted planetary driving roll, preceding supporting disk, back supporting disk, intermediate support axle, pinch roller and transmission mechanism.Planetary driving roll is made up of many rollers, the roller of planetary driving roll is supported on preceding supporting disk and the back supporting disk, the axial line of the axial line of every roller and intermediate support axle is not only not parallel but also non-intersect, and is an angle mutually, drives roller by transmission mechanism and does to rotate in the same way.Pinch roller is arranged in the planetary driving roll periphery, and shape distributes in the shape of a spiral.The outer surface of pinch roller has and the corresponding shape of pipe outer surface, and pinch roller is pressed on the outer surface that is wrapped in the outer heterotypic strip of planetary driving roll, and rotates around wheel pressing shaft.The present invention must not need corresponding large-scale extruder and die head and subdivision mould traction formation system as equipment used in the crawler type subdivision mould manufacturing method, must vacuum forming yet, and the pulling warp shaped device that the utility model adopted is simple in structure, manufacturing and installation are also very convenient, and being fit to make internal diameter is above single wall or double-walled plastic spiral pipe of 100mm.
Accompanying drawing is the structural representation of pulling warp shaped device.
The key equipment---pulling warp shaped device of the manufacturing plastic spiral pipe that the utility model proposes, as shown in drawings, pulling warp shaped device is made up of the planetary driving roll, preceding supporting disk 1, back supporting disk 2, intermediate support axle 3, pinch roller 4 and the transmission mechanism 5 that are installed on the frame 13.Planetary driving roll is made up of cold hollow roller 6 in many (more than 3 or 3), the two ends of roller 6 are supported on preceding supporting disk 1 and the back supporting disk 2 by bearing 7 respectively, preceding supporting disk 1 and back supporting disk 2 secured in parallel are in the rear and front end of intermediate support axle 3, and it is vertical with intermediate support axle 3, preceding supporting disk 1 usefulness screw 8 is fixedlyed connected with intermediate support axle 3 front ends, back supporting disk 2 is enclosed within on the intermediate support shaft rear end 9, after the supporting disk 2 of back, be equipped with one and regulate spiral shell dish 10, regulate spiral shell dish 10 and use thread connection with intermediate support shaft rear end 9, hold out against back supporting disk 2 with being located at the screw of regulating on the spiral shell dish 10 11 that holds out against, and the circumferential position of fixing back supporting disk 2.The two ends of roller 6 are evenly distributed on preceding supporting disk 1 and back supporting disk 2 with the concentric diameter of intermediate support axle 3 and are respectively on the circumference of D1 and D2, and D1＞D2, adjust the position also with holding out against screw 11 location by rotating back supporting disk 3, make the axial line and intermediate support axle 3 axial lines of every roller letter 6 not parallel non-intersect again, and be an angle mutually.The front end of roller 6 has drive sprocket 12 or helical gear as shown in drawings, links to each other or the helical gear engagement with the chain that transmission mechanism 5 matches, and drives every roller 6 by transmission mechanism 5 and does to rotate in the same way.Several pinch rollers 4 are arranged in the planetary driving roll periphery, and shape distributes in the shape of a spiral.The surface of pinch roller 4 has and the pipe outer surface corresponding shape.
Claims (2)
