A plurality of mounting holes which are formed by stretching and piercing are uniformly distributed in the length direction of the master slice, each mounting hole is welded to a high-frequency welded pipe by brazing, and a solder coating is arranged on the cross section of each mounting hole. The processing method comprises the following steps: the master slice is placed on a concave die of a punching machine, one side, which is provided with the solder coating, of the master slice, faces the concave die, and a convex die is used for stretching the master slice, so that the mounting hole part of the master slice extends towards the direction of the concave die until the mounting hole part of the master slice, deformed by stretching, is pierced, and the pierced type mounting holes are formed. The mounting holes in the master slice provided by the invention are formed by stretching and piercing, the linear segments of the mounting holes are lengthened, the matching area of the mounting holes and the high-frequency welded pipe is enlarged, the strength after brazing is good, and the problem of leakage in pipe roots caused by poor welding strength of the radiator after brazing due to limit of the structure of the master slice is solved.
Description
Technical field
The present invention relates to heat radiator of internal-combustion engine core body main piece, specifically a kind of heat radiator of internal-combustion engine puncture type main leaf and processing method thereof.
Background technique
Radiator is important parts in internal-combustion engine cooling system, if cooling bad, leak and will directly affect the life-span of internal-combustion engine, the fault of the cylinder that even occurs rising; And main leaf is as the important component part of radiator core body, its structure and directly have influence on sealing and operational safety with cooling tube soldering strength.Therefore, the design of main leaf has considerable meaning.
At present, the main leaf structure of plastic-aluminum heat radiator of internal-combustion engine and installation are as shown in Fig. 1～4, and main leaf 1 carries out soldering after assembling with ratio-frequency welded tube 2, and the scolder 3 forming after scolder coating 4 thawings by main leaf 1 surface after soldering is integrally welded by main leaf 1 and ratio-frequency welded tube 2.But because the mounting hole 12 of traditional main leaf 1 is that punching forms, the section 5 open coating 4 of mounting hole 12; Therefore, traditional main leaf 1 with after ratio-frequency welded tube 2 solderings, be to be only connected in a small amount by scolder 3 is local, exist face of weld little, the problem such as join strength is poor, easily causes automobile to ftracture, come off, the phenomenon of radiator leak at the road conditions of the jolting lower core body main piece scolder that travels.
Summary of the invention
The problems referred to above that exist in order to solve traditional main leaf structure, the object of the present invention is to provide a kind of heat radiator of internal-combustion engine puncture type main leaf and processing method thereof.
The object of the invention is to be achieved through the following technical solutions:
Main leaf length direction of the present invention is evenly equipped with a plurality of by stretching, puncture the mounting hole of formation, each mounting hole all with ratio-frequency welded tube Welding.
Wherein: on the section of described mounting hole, there is scolder coating.
The processing method of heat radiator of internal-combustion engine puncture type main leaf of the present invention is: main leaf is placed on the die of punch press, main leaf have scolder coating one facing to die, punch first carries out pull and stretch to main leaf, the mounting hole portion of main leaf is extended to the direction of die, until the mounting hole portion of the main leaf of tensile buckling is punctured, thereby the mounting hole of formation puncture type.
Wherein: the lower end of described punch is most advanced and sophisticated, and the cutting edge of die is round-corner transition; The gap of described punch and die equals the thickness of main leaf; Described main leaf drawn, the straightway that punctures the mounting hole of formation elongate, the area increase coordinating with ratio-frequency welded tube.
Advantage of the present invention and good effect are:
1. the mounting hole on main leaf of the present invention is by stretching, puncture formation, the straightway of mounting hole elongates, increase with the area that coordinates of ratio-frequency welded tube, pricker as deposited strength is good, has solved radiator because main leaf structure limits after its soldering the poor pipe causing of weld strength with the problem of place's leakage.
2. on the mounting hole section of main leaf of the present invention, have scolder coating, after soldering, section can be closely integrally welded with ratio-frequency welded tube, and weld strength is good.
3. the processing method of main leaf mounting hole of the present invention is stretched, punctures and form main leaf by the punch and matrix tool in large gap, the mounting hole straight line segment length of the puncture type main leaf forming like this, coordinate area large with ratio-frequency welded tube, its section of hole simultaneously forming due to this technique has scolder coating, after soldering, its section can be closely integrally welded with ratio-frequency welded tube, and weld strength is good.

Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Fig. 5～8, main leaf 11 of the present invention is evenly equipped with a plurality of by stretching, puncture the mounting hole 12 of formation at its length direction, each mounting hole 12 all with ratio-frequency welded tube 2 Weldings.On the section 7 of mounting hole 12, there is scolder coating 10, like this after main leaf 11 and ratio-frequency welded tube 2 solderings except 11 scolders of locating 6 of main leaf, the section 7 of main leaf 11 also has scolder coating 10, after soldering, main leaf 11 closely welds together with ratio-frequency welded tube 2, bonding area is large, weld strength is good, thus solved radiator owing to disliking main leaf scolder cracking under condition condition, the hidden danger revealed of the radiator that causes of coming off.
The processing method of main leaf of the present invention is:
Main leaf is placed on the die 9 of punch press, main leaf have scolder coating 10 one facing to die 9; The lower end of punch 8 is most advanced and sophisticated, and the cutting edge of die 9 is round-corner transition, and the gap of punch 8 and die 9 equals the thickness of main leaf.
Punch 8 first carries out pull and stretch to main leaf, and the mounting hole portion of main leaf is extended to the direction of die 9, until the mounting hole portion of the main leaf of tensile buckling is punctured, thereby the mounting hole 12 of formation puncture type.The thick aluminium sheet (being main leaf 11) of processing 1.5mm of take is example, and under 30 tons of blanking forces, punch press once-through, can go out 20 slotted holes, and each slotted hole is of a size of: long * wide: 16 * 2mm, hole depth can reach 4mm.
The puncture type main leaf 11 forming like this, the more traditional main leaf of straightway of its mounting hole 12 elongates, and the area coordinating with ratio-frequency welded tube 2 increases; Simultaneously, the section 7 of the mounting hole 12 forming due to this processing method has scolder coating 10, after soldering, section 7 can be closely integrally welded with ratio-frequency welded tube 2, and weld strength is good, solved radiator because of main leaf scolder cracking, the hidden danger revealed of the radiator that causes of coming off.
