Description
The present invention relates to the manufacture method and the heat exchanger fin metal pattern of radiator fin for heat exchanger, relate in particular in the manufacture method of the radiator fin for heat exchanger that forms the tape spool ring perforation that the heat supply exchange passes with pipeline on the sheet metal and be formed at the heat exchanger fin metal pattern that cylindrical portion on the sheet metal is implemented the processing of attenuate pull and stretch and formed the tape spool ring perforation that the heat supply exchange passes with pipeline.
The radiator fin for heat exchanger that is used for the radiating part of heat exchanger such as thermoregulator is the tape spool ring perforation that a plurality of specified altitudes are set on square sheet metals such as aluminum thin plate.The radiating part of the heat exchanger that is formed by this radiator fin for heat exchanger is overlapping behind each tape spool ring perforation consistency from top to bottom with the multi-disc radiator fin for heat exchanger, will insert these tape spool rings perforation to form an integral body with pipeline by the heat exchange that the high metal of thermal conductivity factors such as copper is made simultaneously.
As the manufacture method of this radiator fin for heat exchanger, adopt the manufacture method shown in Fig. 9 A～Fig. 9 D and Figure 10 A～Figure 10 F.
Manufacture method shown in Fig. 9 A～Fig. 9 D is at first in sheet metal 100 enterprising eleven punch 11 processing backs plunging processing to be done in the perforation that wears, form by protrusion sheet 102 and surround cylindrical portion 101 (operation of Fig. 9 A) on every side, then, on the protrusion sheet 102 of cylindrical portion 101, carry out the processing of attenuate pull and stretch, to protrude sheet 102 simultaneously and extend, form the axle collar 104 (operation of Fig. 9 B and Fig. 9 C) of specified altitude.Then, the leading section bending back formation flange 105 (operation of Fig. 9 D) with the axle collar 104 can obtain the perforation of tape spool ring.To call the manufacture method shown in Fig. 9 A～Fig. 9 D in the following text is attenuate pull and stretch processing method.
Manufacture method shown in Figure 10 A～Figure 10 F is made up of following operation.At first, form the kiver shape protuberance 106 of truncated cone, its bottom surface diameter is greater than the opening diameter (operation of Figure 10 A) of the tape spool ring perforation that forms on sheet metal 100, on one side and carry out on one side making its deep-draw that raises highly gradually process (operation of Figure 10 B, Figure 10 C, Figure 10 D) reduced of this kiver shape protuberance 106.And on the container-like protuberance 109 that has been processed to form specified altitude through deep-draw, implement perforation processing back this perforation is done plunging processing to form the axle collar 104 (operation of Figure 10 E).Then, will form flange 105 (operation of Figure 10 F) after the axle collar 104 leading section bendings, can obtain the perforation of tape spool ring.Below the manufacture method shown in Figure 10 A～Figure 10 F is called the deep-draw processing method.
Can be with the radiator fin for heat exchanger that the manufacture method of the radiator fin for heat exchanger shown in Fig. 9 A～Fig. 9 D and Figure 10 A～Figure 10 F obtains by the punch process manufacturing.In the manufacture method of the radiator fin for heat exchanger shown in this Fig. 9 A～Fig. 9 D and Figure 10 A～Figure 10 F, attenuate pull and stretch processing method shown in Fig. 9 A～Fig. 9 D is compared with the deep-draw processing method shown in Figure 10 A～Figure 10 E, because its manufacturing schedule is short, can realize of the miniaturization of the used heat exchanger fin of punch process with metal pattern.
Heat exchanger fin used in the attenuate pull and stretch processing method shown in Fig. 9 A～Fig. 9 D can use heat exchanger fin metal pattern shown in Figure 11 with in the metal pattern.Figure 11 is the partial sectional view of heat exchanger fin with metal pattern.This heat exchanger fin is made of patrix 300 and counterdie 400 with metal pattern, fixes former 116 with the metallic plate 112,114 that constitutes patrix 300.
The front end of former 116 stretches out from the general plan that faces down of the metallic plate 114 of formation patrix 300 downsides, and the knockout pin 118 owing to the power of spring 120 to counterdie 400 direction reinforcings inserts in the formers 116 the internal face sliding-contact of its outer peripheral face and former 116.Knockout pin 118 is a kind of release member as described later, that is, drift 128 enters in the former 116, and cylindrical portion 101 is implemented the processing of attenuate pull and stretch, then along with the drift 128 that retreats moves, the residual axle collar 104 that is attached on former 116 internal faces is released.
In addition, by the members 132 that insert in the cylindrical member of being fixed by the metallic plate 122,124 of the bottom that constitutes counterdie 400 126, the state that the drift 128 that makes the attenuate pull and stretch process usefulness stretches out from cylindrical member 126 with its leading section is fixed on the counterdie 400.Diameter is that the processing of attenuate pull and stretch is finished by the bight 136 of drift 128 with the guide portion of drift 128 to cylindrical portion 101 guiding that surrounded by protrusion sheet 102 less than the leading section 138 of the drift 128 of these drift 128 main parts.
Near the leading section of the drift 128 that so is fixed on counterdie 400 bottoms, because the effect of afterburning member (not shown) and, and separate predetermined distance between the bottom and be provided with stripper plate 130 to the direction reinforcing of patrix 300.Wear the perforation 134 that can supply drift 128 to pass through on this stripper plate 130, when not loading on the stripper plate 130, regulate the position of stripper plate 130, so that the front end of drift 128 is lower than the upper side of stripper plate 130.
Upper side at above-mentioned stripper plate 130 puts metallic plate 100, forms on it to be protruded the cylindrical portion 101 that sheet 102 surrounds periphery, and this cylindrical portion 101 is carried out the processing of attenuate pull and stretch.
At this moment, patrix 300 moves downwards, the counterdie pushing member (not shown) that is located on the patrix 300 just pushes downwards with stripper plate 130 butts and with stripper plate 130, like this, and the distance between the bottom has just shortened, and the front end of drift 128 is by boring a hole 134 and reach the upper side of stripper plate 130.Because patrix 300 continues to move downwards, the leading section of the drift 128 that stretches out from the upper side of stripper plate 130 is with regard to the power that overcomes spring 120 and knockout pin 118 is pushed upward, enter simultaneously in the former 116, and and the internal face of former 116 between cylindrical portion 101 is carried out the processing of attenuate pull and stretch.
Then, patrix 300 is moved upward, and the leading section of drift 128 retreats in former 116.At this moment, knockout pin 118 since the power of spring 120 and with drift 128 butts that retreat, the direction to counterdie 400 descends simultaneously, the residual axle collar 104 that will be attached to former 116 internal faces is released.
When adopting attenuate pull and stretch processing method (using above-mentioned heat exchanger fin metal pattern shown in Figure 11) shown in Fig. 9 A～Fig. 9 D, can form the axle collar 104 of vertical metal thin plate 100.Therefore, tape spool ring perforation that obtains at last and the heat exchange of inserting wherein are good with adaptation between the pipeline.
Yet the height of the axle collar 104 that obtains with the attenuate pull and stretch processing method shown in Fig. 9 A～Fig. 9 D is easily by about the thickness of sheet metal 100 institute.Therefore, seeking the occasion of heat exchanger lightweight etc., promptly to realize the lightweight of radiator fin for heat exchanger in recent years, keep the intensity of radiator fin for heat exchanger etc. again, need to adopt than original harder thinner sheet metal.And as adopt than original harder thinner sheet metal, and bore a hole with the perforation that the attenuate pull and stretch processing method shown in Fig. 9 A～Fig. 9 D forms the tape spool ring, may be difficult to obtain the axle collar of specified altitude.
In addition,, extremely difficult at heat exchanger fin shown in Figure 11 with in each drift 128 and the metal pattern of packing into corresponding to the central shaft of the former 116 of each drift 128 in full accordly with in the metal pattern, can in the assembly precision scope, produce between two central shafts and misplace.In case produce two dislocation between central shaft, when in former 116, having inserted drift 128, will produce between the internal face of former 116 and drift 128 outside wall surface unevenly at interval, the attenuate pull and stretch degree that the protrusion sheet 102 of cylindrical portion 101 is carried out can change.Therefore, in case the dislocation of two central shafts between drift 128 and the former 116 is big, the tape spool ring perforation that then obtains will be as shown in figure 12, and all wall thickness of the axle collar 104 can become inhomogeneous, the unbalanced axle collar can take place, and promptly the front end of the axle collar 104 forms the beveled end to the inclination of heavy wall direction.
On the other hand, when adopting the deep-draw processing method shown in Figure 10 A～Figure 10 F, on one side can the substantive thickness of keeping sheet metal 100 form the container-like protuberance 109 of specified altitude on one side.Therefore, even adopt, also can form the axle collar 104 of specified altitude than original hard and thin sheet metal.
Yet container-like protuberance 109 is that circular cone shape kiver shape protuberance 106 diameter reduction that will form on sheet metal 100 form the back so that it raises highly gradually.Therefore, the vertical sectional shape of the cylindrical portion 104 that forms in the 109 enterprising eleven punch 11s processing of container-like protuberance and plunging processing back be " eight " font, and the final tape spool ring that forms is bored a hole also as shown in figure 13, and its vertical sectional shape becomes " eight " font.
In case in vertical sectional shape is the tape spool ring perforation of " eight " font, insert heat exchange with pipeline 110, just between the internal face of the axle collar and the outside wall surface of heat exchange, form the gap easily with pipeline 110, can reduce the adaptation of the two.
For this reason, the object of the present invention is to provide a kind of manufacture method of radiator fin for heat exchanger, adopt this method, promptly use the tape spool ring perforation that also forms specified altitude than original hard and thin metallic plate easily, also be to provide a kind of cylindrical portion of easy formation front end height unanimity and member to make simple radiator fin for heat exchanger metal pattern.

The form that carries out an invention
The present invention at first, forms kiver shape protuberance 12 (operations of Figure 1A) on sheet metal 10 shown in Figure 1A～Fig. 1 G.This kiver shape protuberance 12 is implemented multistage (Figure 1A～Fig. 1 G is three sections) deep-draws processing, the diameter of kiver shape protuberance 12 is dwindled gradually, form the container-like protuberance 18 (Figure 1B, Fig. 1 C, Fig. 1 D) of specified altitude.This container-like protuberance 18 is owing to be with the reduced of kiver shape protuberance 12 and formation, so the wall portion thickness of container-like protuberance 18 is identical with sheet metal 10 in fact.Then, in the processing of boring a hole of the upper side of this container-like protuberance 18, and plunging processing back is carried out in the perforation that forms form cylindrical portion 20 (Fig. 1 E).The wall portion thickness of this cylindrical portion 20 is also identical in fact with sheet metal 10.
Then, cylindrical portion 20 is being implemented the processing of attenuate pull and stretch forming the axle collar 22 backs (Fig. 1 F), the leading section of the axle collar 22 is being bent to flange 24, forming tape spool ring perforation 26 (Fig. 1 G).
Form above-mentioned tape spool ring perforation 26, on the separable pair of metal mould, adorning corresponding with the operation of Figure 1A～Fig. 1 G respectively former and drift etc. successively at the throughput direction of sheet metal 10.
Yet it is more that the operation shown in Figure 1A～Fig. 1 G and the deep-draw processing method shown in Figure 10 A～Figure 10 F are compared operation, so heat exchanger fin is maximized with metal pattern.
About this point, the present invention can prevent as far as possible that by implement the operation (Fig. 1 E) of perforation processing and plunging processing and the operation (Fig. 1 F) of attenuate pull and stretch processing at the same position of metal pattern heat exchanger fin from maximizing with metal pattern.
The heat exchanger fin that can implement perforation processing, plunging processing and the processing of attenuate pull and stretch at same position with metal pattern as shown in Figure 2.Fig. 2 makes the partial sectional view of the heat exchanger fin of radiator fin for heat exchanger with metal pattern with the manufacturing process shown in Figure 1A～Figure 10 F, be container-like protuberance 18 enforcement perforation processing to the specified altitude of on sheet metal 10, implementing deep-draw processing back formation, after the perforation that will obtain is processed to form cylindrical portion 20 by plunging again, cylindrical portion 20 is implemented the attenuate pull and stretch be processed to form the axle collar 22.
This heat exchanger fin is made of separable patrix 30 and counterdie 50 with metal pattern, by the metallic plate 31,32,33 that constitutes patrix 30 former 34 and drift hammer 36 is installed.The state that drift hammer 36 protrudes towards the direction of counterdie 50 with its front end inserts in the former 34 and by metallic plate 31,32 and fixes.Former 34 is with the face slightly downwards state of the protrusion installation of its front end from the metallic plate 33 of the downside of formation patrix 30, and as shown in Figure 3, be embedded in a gap in the accommodating chamber 35 that forms between the metallic plate 31,33, that is, on the side of former 34 reaches, form gap 38,39.Therefore, former 34 can move in same plane.The mobile range of this former 34 is width of relative drift hammer 36 mobile spaces 38.
In addition, the metallic plate 51,52,53 of the bottom by constituting counterdie 50 fixes tubular drift 54.This tubular drift 54 is when patrix 30 and counterdie 50 matched moulds, and the leading section that is fixed on the drift hammer 36 on the patrix 30 inserts, and forms hollow hole 55 on it, adds the chip that produces man-hour for perforation and passes through.The external diameter of the leading section 56 of above-mentioned tubular drift 54 becomes the guide portion of the perforation that forms to drift hammer 34 less than the main part 57 of tubular drift 54.The rake 58 that forms the inclined plane between above-mentioned leading section 56 and main part 57 is parts of the perforation that perforation is processed to form being implemented plunging processing, and 59 in the bight that rake 57 and main body are 56 is a part of the cylindrical portion 20 that is processed to form through plunging being implemented the processing of attenuate pull and stretch.
Near the leading section 56 of the tubular drift 54 that is fixed in above-mentioned counterdie 50 bottoms, be provided with the spring 60 that is used as afterburning member separates predetermined distance between patrix 30 direction reinforcings and bottom stripper plate 62.Be provided with the perforation 64 that can pass for the main part 57 of tubular drift 54 on this stripper plate 62, when load did not impose on stripper plate 62, stripper plate 62 positions were adjusted to below the upper side that the front end that makes tubular drift 54 is in stripper plate 62.
In addition, on metal pattern shown in Figure 2, implement identical with used metal pattern structure in the part of the corresponding processing of operation shown in Figure 1A～Fig. 1 D and the traditional deep-draw processing method.
Between heat exchanger fin shown in Figure 2 is with the patrix 30 of metal pattern and counterdie 50, send into the sheet metal 10 that forms container-like protuberance 18, and the matched moulds of beginning patrix 30 and counterdie 50.At this moment, in case patrix 30 begins to descend, be located at counterdie pushing member (not shown) on the patrix 30 just with stripper plate 62 butts and overcome the power of spring 60 and stripper plate 62 is pushed downwards, and the leading section 56 of tubular drift 54 that has passed as shown in Figure 4, the perforation 64 of counterdie 50 protrudes at the upper side of stripper plate 62.The leading section 56 of the tubular drift 54 that protrudes at the upper side of stripper plate 62 is inserted in the container-like protuberance 18 that forms on the sheet metal 10, and container-like protuberance 18 is done the position adjustment as shown in Figure 2.
In addition, because patrix 30 descends, push stripper plate 62 to below, the leading section 56 that makes tubular drift 54 is from the upper side protrusion of stripper plate 62 and the container-like protuberance 18 of insertion sheet metal 10, and the front end that is fixed on the drift hammer 36 on the patrix 30 just inserts in the hollow hole 55 of leading section 56 of tubular drift 54, and the upper side of container-like protuberance 18 is implemented perforation processing to form perforation.The aperture area of this perforation is less than the area of container-like protuberance 18 upper sides.
Owing to the chip that perforation processing produces is discharged outside metal pattern through the hollow hole 55 of tubular drift 54.
Patrix 30 continues to descend, and the leading section 56 of tubular drift 54 is more protruded from the upper side of stripper plate 62, makes the perforation of 59 pairs of container-like protuberance 18 upper sides of rake of tubular drift 54 implement plunging processing, to form cylindrical portion 20.
Patrix 30 continues to descend, and just as shown in Figure 5, by the bight 59 of former 34 and tubular drift 54, the cylindrical portion 20 of inserting the former of being adorned on the patrix 30 34 is implemented the processing of attenuate pull and stretch.
State the attenuate pull and stretch on the implementation and add man-hour, make the central shaft of 54 liang of sides of former 34 and tubular drift in full accord extremely important for forming the identical axle collar 22 of front end height.Yet, be very difficult in the central shaft metal pattern of packing in full accord with former 34 and 54 liang of sides of tubular drift.
About this point, former 34 is to be embedded in the accommodating chamber 35 that forms on the patrix 30 with the state that forms gap 38,39 as shown in Figure 3.Therefore, add man-hour at enforcement attenuate pull and stretch, former 34 can relative fixed on counterdie 50 tubular drift 54 and move on same plane, can the interval between former 34 internal faces and tubular drift 54 outside wall surface be adjusted to all uniformly-spaced along the full week of former 34 internal faces.
That is, during the dislocation of the central shaft of the former 34 in being contained in metal pattern and 54 liang of sides of tubular drift, the interval between former 34 internal faces and tubular drift 54 outside wall surface is just inhomogeneous.Therefore, adding man-hour implementing the attenuate pull and stretch with above-mentioned former 34 and 54 pairs of cylindrical portion of tubular drift 20, the power that former 34 is applied, the central shaft of former 34 can narrower part deflection gap wide portions apply from gap between former 34 internal faces and tubular drift 54 outside wall surface in the power that vertical direction applies especially relatively.The former 34 that has been applied in this angular force leaves in the accommodating chamber 35 of 38,39 ground, gap embedding patrix 30, so to being moved by the direction of the application of force.In case mobile end, promptly as shown in Figure 6, two central shafts of former 34 and tubular drift 54 are consistent, and along the full week of former 34 internal faces the internal face of former 34 and the interval between tubular drift 54 outside wall surface are adjusted to all uniformly-spaced.As a result, can obtain the axle collar 22 of front end height unanimity along the uniform attenuate pull and stretch processing of implementing in full week of cylindrical portion 20.
