Description
Technical field
The present invention relates to automobile engine cooling technology field, particularly, relate to a kind of can with slice weldering collapsible radiating tube and production method.
Background technology
At present, the manufacture of the radiating tube of automobile engine charge air cooler is divided into seamless cold-drawn and high-frequency welding, and the product that above-mentioned two kinds of manufactures are produced corresponds to drawn tube and ratio-frequency welding adapter.It is high that drawn tube has intensity, and cleannes are high, and technique is simple, the advantages such as energy consumption is low, mould small investment, but seamless cold-drawing technology cannot produce the radiating tube with many composite materials.High-frequency induction welding technique can overcome the weakness of seamless cold-drawing technology, can produce the radiating tube with many composite materials, and there is the high advantage of production efficiency, but to there is again energy consumption high for high-frequency induction welding technique, the deficiency that equipment investment is large, has a strong impact on the production cost of radiating tube.
Summary of the invention
For defect of the prior art, the object of this invention is to provide a kind of can with slice weldering collapsible radiating tube and production method.
Preferably, according to an aspect of the present invention, a kind of collapsible radiating tube that can weld with slice is provided, this can comprise with the lateral cross section of the collapsible radiating tube of slice weldering: the first long side, second long side, first curved end and the second curved end, first long side, first curved end, second long side and the second curved end join end to end successively, second curved end is double-decker, second curved end comprises inner and outer wall, second long side extends to inside the first long side to the second curved end and forms inwall, the end points of inwall extends to the corner that the first long side is connected with the second curved end, inwall is also provided with in the corner that the second long side is connected with the second curved end dodges a little, first long side extends to form outer wall to the second curved end, the end points of outer wall extends to dodges a place.
Preferably, can be round rectangle with the lateral cross section of the collapsible radiating tube of slice weldering.
According to another aspect of the present invention, provide a kind of and produce above-mentioned with the method for the collapsible radiating tube of slice weldering, can comprising the following steps:
Step 1: launch aluminium volume, and banded aluminium foil is introduced roll extrusion wheels;
Step 2: aluminium foil, through some groups of continuous print roller set, is progressively folded into radiating tube shape;
Step 3: after last group roller set, radiating tube is completely shaping, and now radiating tube cuts off by length on demand;
Step 4: the radiating tube of the length that meets the requirements is used for next process, is assembled into radiator centre, and enter soldering oven, realizes the lead welding and shaping of radiating tube body in radiator centre brazing process.
The collapsible radiating tube that can weld with slice of the present invention, owing to adopting banded aluminium foil roll forming, therefore when selecting the aluminum foil material with soldering composite bed to carry out radiating tube folding forming, radiating core assembling can be directly used in without the need to pre-welding after pipe forming, when the radiating core assembled is when by soldering oven, soldering composite bed on body can at high temperature melt, and the inside and outside wall of the second curved end will seam when the time comes, thus realizes the channel welds of radiating tube body.
Every advantage of the comprehensive existing radiating tube of the present invention, proposes a kind of brand-new design of the collapsible radiating tube that can weld with slice, and this design can replace drawn tube and ratio-frequency welding adapter completely, is applied to automobile radiators particularly charge air cooler.Possess the high strength in traditional design, high cleanliness, every advantages such as corrosion resistance is good, and production efficiency is high, and energy consumption is low, and equipment investment low cost is low simultaneously, and the production of many composite beds pipe can have been realized.Compared with prior art, the present invention has following beneficial effect:
The present invention adopts the continuous roll extrusion of multistage briquetting roller and plastic, structure is simple, easily manufactured, simultaneously, because this pipe adopts banded aluminium foil roll forming, therefore, only need select the aluminium foil of different composite side mark lattice, just can realize the manufacture requirements of multiple composite bed pipe, and the mould structure manufacturing this kind of radiating tube be simple, with low cost.Further, owing to eliminating pre-welding, while reducing production power consumption, it also avoid the welding slag that body is formed because of pre-welding, there is cleanliness factor high.In addition, the present invention can make body have larger wall thickness and intensity with the structure of the coincidence overlap joint of the collapsible radiating tube of slice weldering, thus makes the radiator of employing this kind of radiating tube have stronger anti-stone to hit ability and resistance to corrosion.The present invention can be used for all kinds vehicles such as car, minicar, minibus and engineering truck, applied widely.Therefore, compared with prior art, of the present invention can with slice weldering collapsible radiating tube has high strength, high cleanliness, production technology is simple, equipment investment cost is cheap, production efficiency is high, energy consumption is low and the advantage of model applied widely.
