Operation principle of the present invention:
Solderability multi-cavity aluminium-plastic composite section technology is a cover system technology, and it is realized by following three aspects:
1. section material section design
The solderability that the Section Design of aluminium-plastic composite section is necessary for aluminium-plastic composite section provides prerequisite.In other words, why aluminium-plastic composite section can weld, and its one of the main reasons is that these conditions are because the section after plastic-aluminum combined provides necessary condition for it can weld:
(1) section material section must possess machinability, for feasible condition is created in imitative type cutting.
(2) section material section must possess the solderability after the cutting, is that feasible condition is created in the section welding after the cutting, and promptly the shape and the position of non-solder side will be avoided in welding back weldering meat shape and position, makes its weldering meat can not hinder the joint of non-solder side in welding process.
2. the design success of special equipment " imitative type cutting machine ".
" imitative type cutting machine " is a key equipment in the aluminium-plastic composite section welding procedure, the not design of imitative type cutting machine success, the solderability of aluminium-plastic composite section is not just known where to begin yet, the solderability of aluminium-plastic composite section, mainly be meant the welding of plastics, only need cooperate tightly for the requirement of aluminium to get final product.But, two kinds of materials are combined with each other, a kind of material requirements welding, and another kind of material does not require welding, but two kinds of materials of postwelding must and require on same plane in conjunction with tight, the task of Here it is imitative type cutting machine, promptly before welding, after the aluminium-plastic composite section blanking (press given length of drawing and weld bond angle) to press the section material section profile apart from welding 3mm place, plane along the welding plane in the weld bond part, accurately aluminium is partly cut away by soldering angle.Expose welding portion.Finish and be welding of aluminium-plastic composite section after this work sufficient and necessary condition is provided.
The realization of a technology is difficult to independently to finish, and it is the support that needs the relevant industries technology, and an invention of overlapping rational process will consider the feasibility of supporting technology equally.We only need universal design and standard machinery manufacturing to realize at this " imitative type cutting machine ".From milling by mimicking the schematic diagram as can be seen:
(1). machining accuracy realizes easily
Milling Process itself is that angle precision or cutting face surface accuracy all are easy to realize just than common sawing machining accuracy height.Can satisfy the preceding cutting stock precision requirement of welding on the machining accuracy fully.
(2). machining locus is realized easily
As can be seen from the figure imitative type track only needs the resultant motion of X-axis and Y-axis to realize, and this realizes than being easier in Machine Design, and the pattern structural scheme of mechanism is just realized one of mechanism of this motion.Can also make good use of multi-method.
On TRAJECTORY CONTROL, by mimicking one of method of various control track, forming techniques such as numerical control, programming can easily be finished this function, but other equipment costs are higher.
3. to the transformation of conventional plastic welding machine
There has been imitative type to mill equipment and can have finished the preceding preparation of welding on request, but, how to make welding plane and non-welding plane after the welding be in same plane accurately? this need carry out a minor operation to the conventional plastic welding machine: No. three stopping means that promptly remove common welding machine, replace three spacing hard retainings with non-welding material, so just can guarantee that aluminium-plastic composite section has been in same plane accurately at two kinds of materials of postwelding, and improved welding machine is the double-purpose welding machine, during weldering common plastics section bar, only need to install a block on the nipper additional and get final product pressing down.
The realization of above three aspects has been arranged, just can realize the weldability of aluminium-plastic composite section, only needed in the welding procedure of common plastics section bar, to add the imitative type miller preface of an end face as for the welding procedure overall process and get final product.Therefore the welding procedure overall process is no longer described.
Plastic-aluminum combined technology also is to weld one of important component part of plastic-aluminum combined technology, but it is a mature technology on equipment, and we have used the part of this technology, but have designed special equipment.
