Description

A kind of plastic tube body welds the processing method and its realization device of plastic part with holes
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
In order to make up the defect of prior art, the present invention provides a kind of processing method that plastic tube body welds plastic part with holes And its realization device, intensity and sealing performance after making welding can meet requirement.
The technical problems to be solved by the invention are achieved by the following technical programs:
A kind of processing method that plastic tube body welds plastic part with holes, includes the following steps:
S1: plastic tube body and perforated plastic part are clamped respectively;
S2: heating device is moved to the welding surface position of plastic tube body and perforated plastic part, and welding surface is heated, will be welded Face is heated to plastic molting state;Wherein, the heating device includes infrared heating device and hot plate heating device, described infrared 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:
Stationary fixture is used for fixed plastics tube body and perforated plastic part;
Infrared heating device is set between stationary fixture, for heating the welding surface of the perforated plastic part;

Further, the stationary fixture includes for clamping the upper mold of plastic part with holes, set on lower part of upper die for pressing from both sides The lower die of plastic tube body is held, the upper mold driving dress for driving upper mold vertically to move back and forth is fixed in the upper mold It sets, the lower die driving device for driving lower die vertically to move back and forth is fixed in the lower die.
Further, further include heater driver, be fixed on the infrared heating device and hot plate heating device, use It is moved back and forth in the horizontal direction in the driving infrared heating device and hot plate heating device.
In the present invention, infrared heating device and hot plate heating device are driven in the horizontal direction simultaneously using heater driver It moves back and forth, by the technological parameter of Reasonable Regulation And Control infrared heating device and hot plate heating device, so that right in the same time The heating effect of perforated plastic part and plastic tube body reaches unanimity, so that simple to operate.
It further, further include controller, the stationary fixture, infrared heating device, hot plate heating device and heating are driven Dynamic device is electrically connected with the controller.
The invention has the following beneficial effects:
In the present invention, when plastic tube body welds plastic part with holes, traditional simple use hot plate heating welding or red is changed Additional thermal weld, and select to use perforated plastic part infrared heating, plastic tube body is heated using hot plate, is changed by above-mentioned Into not only can guarantee weld strength, equally can guarantee sealing performance at welding position.
The good product consistency of welding processing of the invention, high production efficiency is easy to operate, saves manpower.
