Description
Technical field
The present invention relates to pipeline processing technical fields.
Background technique
Pipe is the main member for constituting pipeline, and pipe has steel pipe, cast iron pipe, concrete reinforced pipe, nonmetallic by material
It manages several.It is raw material that plastic tube, which is usually with synthetic resin, that is, polyester, stabilizer, lubricant, plasticizer is added etc.,
It is formed in tuber through extrusion process in the method for " modeling ".Since it has light, corrosion-resistant, good appearance, without bad gas
Taste, handling ease, it is easy for construction the features such as, be all more and more widely used in numerous areas.It is mainly used as house
The tap water supply system of building is piped, drains, being vented and blowdown sanitary pipe, subsoil drain system, rain pipe and electric wire
Matched penetration pipe etc. is installed.
For the use for adapting to different operating field, plastic tube is often cut into different length according to actual needs, is moulded
After expects pipe is cut, in order to facilitate the connection and sealing of plastic tube, need to carry out flange processing in the nozzle of plastic conduit.Pass through
The plastic tube practicability of flange is stronger, and one side nozzle becomes smooth, it is not easy to hurt sb.'s feelings, spiral shell is on the other hand installed on flange
Bolt can make plastic tube realize the structure for being similar to flanged joint, and connection is stronger, and sealing effect is more preferable.
Existing flanger structure mainly includes the clamping device fixed for plastic tube, and the mold with high temperature,
The mold can feed motion, the shape of mold is frustum of a cone column.When flange, mold feed motion, the nose cone insertion of mold
In plastic tube, plastic tube is softened by the heating of mold, and plastic deformation, plastic tube occurs under the promotion of the mold of cone
Nozzle is bent outwardly deformation and realizes flange.But due to mold can only the inner wall of plastic tube heated, for some tube walls compared with
Thick plastic tube, the inner and outer wall uneven heating of mold plastic conduit when flange, outer wall is not when leading to flange
Softening, feeding mold by force may be easy to cause nozzle to be broken, and flange failure even causes plastic tube to scrap.
Summary of the invention
The invention is intended to provide a kind of plastics nozzle flanging process, realize that plastic tube nozzle is heated evenly in flange, with
Nozzle is prevented to be broken and scrap.
Plastics nozzle flanging process in this programme, including following process flow:
S1. it clamps plastic tube: taking two arc-shaped ferrules relatively hinged, form the logical of full-circle spray pattern between ferrule
Hole is attached between two ferrules using screw；Screw is unclamped, plastic tube is placed between two ferrules, fastens two folders
It holds hoop and locking is fixed with screw, the both ends of plastic tube are all locked by the way of ferrule；
S2. it arranges heating device: taking an installation having heaters and slidably heat slide, be mounted on one along modeling
On the axial sliding rail of expects pipe axial direction, installing several on heating slide can be heated to the heated probe of high temperature, and heated probe is in
It is circular layout and plastics nozzle end is adapted；
S3. hemmer is arranged: setting one radial sliding rail that is vertical with axial direction sliding rail described in step S2 and intersecting,
One flange slide is installed on radial sliding rail, a coniform mold is set on flange slide；
S4. nozzle heats: pushing the feeding of heating slide described in step S2, heated probe is inserted into plastic tube nozzle
In end face, heating from inside to outside is carried out；
S5. flange forms: exiting heating slide, extracts heated probe, pushes the feeding of flange slide described in step S3, mould
Tool pushes nozzle outward bending, carries out flange molding；
S6. cooling and surface treatment: cooling down molding plastic tube flange by the way of air-cooled, removes flange table
The burr in face carries out grinding process to flange.
The utility model has the advantages that the opposite ferrule fastened is through hole shape, it can fit completely with plastic tube outer wall, increase folder
The area held, and be all clamped at the both ends of plastic tube, it is that plastic tube fixation is stronger；The design of heated probe realizes
It is heated out of plastic tube wall, ensure that the uniformity of heating by the heating except interior, make internal wall of pipe orifice and outer wall and energy
Enough sufficiently softenings, setting heating sliding block can guarantee the mobile stability of heated probe；The mold of cone can push nozzle
It deforms, forms flange, flange slide can guarantee the mobile stability of mold.Above scheme compared with prior art, heats
Mode is changed to be heated from plastics inner, and heating is made to become more uniform, realizes being evenly heated for internal wall of pipe orifice and outer wall,
Bating effect is more preferable, and preventing again flange is that nozzle fractures.
Further, during the step S2 arranges heating device, installation one be can be rotated inside heating slide
Shaft, shaft upper end be fixedly mounted a turntable, on the turntable install a rotatable handle, under shaft
One rotatable gear of end installation, and the flank of tooth that processing and the gear engage on axial sliding rail.Turntable is rotated by handle
Shaft rotation is driven, thus the flank engagement with moving gear and axial sliding rail, driving heating sliding block is mobile, keeps operation more square
Just.
Further, during the step S3 arranges hemmer, installing one inside flange slide be can be rotated
Shaft, shaft upper end be fixedly mounted a turntable, on the turntable install a rotatable handle, under shaft
One rotatable gear of end installation, and the flank of tooth that processing and the gear engage on radial sliding rail.Turntable is rotated by handle
Shaft rotation is driven, thus the flank engagement with moving gear and radial sliding rail, driving flange sliding block is mobile, keeps operation more square
Just.
Further, during the step S1 clamping plastic tube, a slidable gear is arranged in the tail end of plastic tube
Block, and be fixed using lock-screw, the axial displacement of plastic tube is limited, plastic tube vibration is prevented.
