Description
Technical field
The present invention relates to automotive plastic parts welding technology fields, weld perforated plastic more particularly to a kind of plastic tube body
The processing method and its realization device of part.
Background technique
There are many automotive plastic parts welding methods, including hot plate heating welding, infrared heating welding, vibration friction welding (FW)
It connects, ultrasonic bonding etc., wherein being most widely used with infrared heating welding and hot plate heating welding method.
Infrared heating welding method refers to being heated to-be-welded pieces with RF transmitter, passes through a level pressure later
Power, time carry out contact pressure maintaining welding, and process can be divided into: the 1. clamping of weldment → 2. with two weldering of infrared heating block heating
The heating element of fitting surface to be welded (infrared heating block is not contacted with to-be-welded pieces surface) → 3. removes → 4. fixture up and down
Molding → 5. weldment fixture is opened → is 6. welded and is completed., difference similar with infrared heating welding method is welded in hot plate heating
For the heating method of to-be-welded pieces.Infrared heating welding is higher to welding surface appearance requirement suitable for product, and welding surface is close
Seal the Product jointing under more demanding equal requirements.Wherein to-be-welded pieces thickness is needed more than 3mm, and otherwise to-be-welded pieces can be due to red
The thermal break-through effect of outer line heat source is whole to soften, and when molding after the completion of heating, can not provide corresponding support force, and then influence weldering
Connect effect.
Hot plate heating welding then needs hot plate to be bonded with to-be-welded pieces surface, and heat conduction is only limited to contact surface, and heat is not
Too fast material deep layer can be penetrated into, but the plastics after thawing can be extruded into contact surface surrounding by hot plate, welding when causing molding
Face contact can be insufficient, and leading to sealing effect not is fine situation, so hot plate welding connection is only applicable to seal welding surface
It is of less demanding, and the part that welding surface appearance requirement is not high, generally thin walled shell or tube body.
The welding that can be often related between plastic tube body and perforated plastic part in automotive plastic parts welding, it is desirable that perforated plastic
It is connected to inside part and plastic tube body, welding position seal request is higher.In the prior art, between plastic tube body and perforated plastic part
Welding otherwise using hot plate heating welding or using infrared heating weld.Inventor in practice, it has been found that plastic tube body with
It when being welded between perforated plastic part, is welded if heated only with hot plate, perforated plastic part and plastic tube body welding bar (plastics
Boss on part is bonded after heating and melting) it can be because hot plate contact is squeezed away after melting should go out molten plastic, after causing molding
Sealing performance is insufficient;If welded only with infrared heating, plastic tube body can cause pipeline to collapse because infrared heat source radiates,
And then holding power can not be provided in molding, cause welding performance insufficient.
In conclusion at present we there are no a kind of welding methods to be suitable for plastic tube body and perforated plastic part for welding
Sealing performance afterwards, pull-off performance, the more demanding situation such as aesthetic measure after welding.
Summary of the invention

Heating device is for heating the perforated plastic part, and the hot plate heating device is for heating the plastic tube body;
S3: recalling heating device, and the fixture for clamping plastic tube body and perforated plastic part carries out molding campaign;
S4: pressure maintaining is cooling.
Inventor has found by numerous studies, is process since perforated plastic part is generally injection molding manner, and general material
Material strip glass, intensity is higher, and welding face thickness is thicker, and infrared heat source radiation not will cause its welding surface and collapse or molten plastic
The case where being all squeezed away can heat modeling with holes so the heating method of perforated plastic part is infrared heating in the present invention in this way
Materials and parts equally can also retain the welding bar of plastic part with holes.Since the material of plastic tube body is softer, added using infrared heat source
It will cause pipeline when hot to collapse, so the heating method of plastic tube body is heated using hot plate in the present invention, such plastic tube body exists
Welding surface and hot plate contact position are that surface is melted when heating, and tube wall is also equipped with certain rigidity, would not be collapsed in molding.
In the present invention, when plastic tube body welds plastic part with holes, changes traditional simple heat using hot plate and weld
Or infrared heating welding, and select to use perforated plastic part infrared heating, plastic tube body is heated using hot plate, by above-mentioned
It improves, not only can guarantee weld strength, equally can guarantee sealing performance at welding position.
In the present invention, by setting hot plate temperature and infrared heat source temperature, make its heating in same time to weldment
Effect reaches unanimity, and those skilled in the art can set according to actual needs.
A kind of device realized above-described plastic tube body and weld the processing method of plastic part with holes, comprising:
