Abstract

The present invention provides an automatic shaping method and structure of fin and connection element. A feeder drives a material belt to enter a punch having a continuous die. The material belt passes a guide device, a bottom die, and a top die of the continuous die to perform operations of punching a central hole, shaping of outer appearance, and hole expansion and drawing. After an a period's interval, the top die is used to shear the material belt, and a pressure piece moves downwards for side shearing. At the same time of shearing, shaped sheet fins are pressured onto the connection element. A stepping device drives the pressure piece to stack the fins on the connection element one by one. The connection elements are arranged at the feeder. The connection element is sent into a positioning device one by one. After the fins are stacked, automatic replacement is performed.

Description

    FIELD OF THE INVENTION
  • The present invention relates to an automatic shaping method and structure of fin and connection element and, more particularly, to a manufacturing method and the mechanical structure thereof, wherein sheet fins shaped by punching are automatically assembled with a connection element one by one following the punching procedure. [0001]
  • BACKGROUND OF THE INVENTION
  • In addition to an integral heat radiator, a conventional heat-radiating device can be formed of a plurality of metallic sheet fins to enhance the whole heat-radiating area. It is characterized mainly in that a connection element is added on the fin structure, and a through hole is correspondingly disposed on each fin so that the connection element can pass through. The bore of the through hole must be slightly larger than the outer diameter of the connection element so that each metallic sheet fin can be positioned on the connection element. [0002]
  • In the conventional manufacturing method, each metallic sheet fin is shaped by one time of punching. As shown in FIG. 1, after a roll of material belt [0003] 10 passes through a feeder winder 11 and then enters a punch 12, a die 13 is used to punch the material belt 10 to become sheet fins 14 shown in FIG. 2. Next, assembly is performed manually. Of course, there is still the manufacturing process of connection element. However, the present invention is independent of how the connection element is manufactured and thus this part will not be further described. As shown in FIG. 2, the fins 14 are slipped into a connection element 15 one by one.
  • Because the degree of joint between the fin and the connection element is high, the assembly is relatively difficult. Moreover, because each fin needs to be manually and slowly moved on the connection element and the connection element is flexible, this action is also difficult. Therefore, manufacturing by means of manual assembly is time-consuming and laborsome. Furthermore, because the cost of manual labor is expensive, and the production is low, the price of manufacture is badly affected. This is because the manufacturing and the assembly are separated, and it is necessary for each fin to undergo the action of alignment, hence detrimental to the requirement of fast manufacturing. [0004]
  • More specifically, in order to meet the requirement of assembly, the bore of the through hole disposed on the conventional fin needs to be slightly larger than the outer diameter of the connection element. After being assembled, not tight match arises so that each fin may be rotatable, hence causing disorderly arrangement of fins. In order to obtain a more stable structure after assembly, a fixing and positioning procedure by means of thermal soldering is further required so that satisfactory manufactures can be obtained. [0005]
  • SUMMARY OF THE INVENTION
  • The object of the present invention is to provide an automatic shaping method and structure of fin and connection element, wherein many sheet fins are made in continuous punching mode, and a through hole is formed on each fin in advance by drawing during the manufacturing process of fin. When a connection element is positioned at the position of a shaped fin, the step of assembly is also performed along with the punching operation, thereby letting sheet fins be slipped onto the connection element via the through hole. A pressure piece is further provided. Motion of the pressure piece is exploited to let the fins move along the connection element. After a certain number of the fins are stacked on the connection element one by one, the next connection element is replaced. Therefore, the action of passing the connection element through the fins needs not to be performed manually or by other special machines, and can directly match the punching process to accomplish the assembly process. Accordingly, waiting time for storage and transportation of the sheet fins is not required. In other words, the sheet fins can be immediately assembled after being manufactured, hence saving the manufacturing cost and assembly time. Moreover, the production per unit time can be increased to let the manufacture has better economy and competitive capacity on the market. [0006]
  • In the present invention, a material belt is driven by a feeder winder to enter a punch having a continuous die. The material belt then passes a guide device, a bottom die, and a top die of the continuous die to perform the operations of punching a central hole, shaping of outer appearance, and hole expansion and drawing. After an interval of a period, the top die is used to shear the material belt, and a pressure piece moves downwards to perform side shearing. At the same time of shearing, the shaped sheet fin is pressured onto the connection element. A stepping device drives the pressure piece to stack the sheet fins on the connection element one by one. The connection element is arranged at the feeder. The connection element is sent into a positioning device of connection element one by one. After the fins are stacked, automatic replacement is performed. [0007]

  • (a) sending the material belt into the punch; [0009]
  • (b) performing shaping by continuous punching in the punch; [0010]
  • (c) initially shearing the material belt; [0011]

  • (e) driving the pressure piece to take the sheet fins to move downwards along the connection element; and [0013]
  • (f) stacking the sheet fins on the connection element one by one. [0014]

  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • As shown in FIGS. [0032] 3 to 5, an automatic shaping structure of fin and connection element of the present invention has a punch 2. Because the structures and action ways of various kinds of punches are almost the same, the basic structure of the punch 2 will not be described in detail in the present invention. A winder 21 is joined at one side of the punch 2. The winder 21 is used to drive a material belt (referring to FIG. 1) to enter the punch 2. The winder is used to let the material belt only move a distance slightly larger than a piece of manufacture.
  • A continuous die [0033] 22 is disposed in the space of the punch 2. The die 22 is positioned in the punch 2. The die 22 has a bottom die 23 and a top die 24. The top die further has a shearing portion and a plurality of punching portions. Because the shapes of the shearing portion and the punching portions are the basic architectures of die, they are not manifested in the figures. Moreover, because the positions and shapes to be punched have modifiability, it is not necessary to limit the shapes and positions of disposition.
  • As shown in FIG. 5, a material belt [0034] 3 passes the guide device 20 and then advances along the bottom die 23 of the die 22. The guide device 20 is positioning guide pieces 30 at two sides of the material belt 3. The positioning guide pieces 30 are respectively disposed at the entry position, the exit position, and the middle position, which will not affect punching. The guide device 20 can also be a pair of ties 38. The material belt 3 passes through the trench of the ties 38. These devices are all limit devices for limiting the material belt 3 to move horizontally, thereby preventing the material belt 3 from springing up.
  • A central hole [0035] 31, two sides 32, an auriform hole 33, two bent sides 34, and a curved bent side 35 in the auriform hole 33 are disposed from the entry direction toward the exit direction on the material belt 3. As can be seen from FIG. 7, totally five times of punching, one after another, are required for the above five shapes. Next, the manufacture undergoes a punching period (five intervals of space) and is then pushed out of the die 22.
  • The present invention is mainly characterized in that an outer frame [0036] 25 beside the top die 24 of the die 22 joins a pressure piece 26, as shown in FIG. 4. The upper end of the pressure piece 26 joins a push device 27 and a stepping control device 28. The pressure piece 26 forms shearing interfaces near the sides of the die 22 and the periphery of the bottom die 23. A shearing tool 7 is disposed between the top die 24 and the bottom die 23 of the die 22, as shown in FIGS. 6 and 10. A far edge line 36 of the material belt 3 is sheared, and the positioned pressurized to break by the pressure piece 26 is a near edge line 37. A plate 29 between the far edge line 36 and the near edge line 37 is punched off. The plate 29 is removed via a slide-off passageway 8 of the bottom die 26. At the same time of punching off, semi-manufactures 30 of sheet fins become free bodies, and can match the connection element along with the pressure piece. The material belt shown in FIG. 5 undergoes the punching of FIG. 6 to show the state of FIG. 7, and is then punched by the pressure piece 26 of FIG. 8. The punching-off state of the plate 26 can be seen with comparison of FIG. 8A and FIG. 6A. The steps of (a) to (d) are described above.
  • A positioning device [0037] 4 of connection element is joined in the punch 2, and is outside the distal end of the bottom die of the die. A connection element 40 is positioned at the positioning device 4, which is exactly below the pressure piece 26. The connection element 40 can be a bar, a pipe, or a thermal tube. The pressure piece 26 takes the punched semi-manufacture of sheet fins 30 to be stacked on the connection element 40 one by one. The positioning device 4 of connection element shown in FIGS. 3 to 8 has at least a pair of holes 43 and 44, which are directly disposed on a slide piece 41 of the punch 2. The slide piece 41 reciprocates on a slide track 42. The action of extracting the connection element 40 from either the hole 43 or 44 is performed manually or by machine.
  • The positioning device [0038] 4 of connection element is matched with the action of the push device 37 of the pressure piece 26 to let the pressure piece 26 perform the action of moving downwards. The push device 27 is usually a hydraulic cylinder to generate reciprocating actions. Because the semi-manufactures 30 are stacked on the outer surface of the connection element 40, the stroke each time needs to diminish gradually. Therefore, the stepping control device 30 is matched. The stepping control device 30 is a small stepper motor to lead the pressure piece 36 to make a recession stroke each time. After the number of semi-manufactures to be stacked is arrived, the pressure piece 26 restores to its original position. The above describes the most important steps of (e) to (f) of the present invention, whereby the semi-manufactures 30 are pushed and positioned by the pressure piece 26 one by one. The pressure piece 26 can be a tube body shown in FIG. 4.
  • As shown in FIGS. [0039] 9 to 13, a feeder 5 is further provided to match the positioning device 4 of connection element, thereby generating positioning and clamping functions of the connection element 40. In other words, a row of connection elements are arranged at the feeder 5, and are sent in by the feeder one by one for assembly processing. The feeder 5 has a slide piece 51. A container 52 for receiving a row of connection elements is joined on the slide piece 51. The slide piece 51 is connected with a stepping push rod 53, which can be a screw rod. The slide pieces 51 at two sides above the container 52 are abutting walls of connection elements. A clamping positioner 54 is disposed at one side of the abutting walls. The clamping positioner 54 is driven by a hydraulic cylinder 55. In other words, the slide piece 51 has a fixing piece 56 and a slide piece 57 thereon. A positioning guide trench 58 is disposed between the two pieces 56 and 57 to receive a connection element 40. The hydraulic cylinder 55 is used to lead the slide piece 57 so that the assembled manufacture can leave from the punch to a conveyance device. The stepping push rod 53 of the feeder 5 is driven by a stepper motor 59. The feeder 5 has an adjustment baffle 50 thereon. The top end of the adjustment baffle 50 contacts the lower end of the connection element 40. A height adjustment screw 6 (shown in FIG. 10, being a height adjustment structure) is joined at the lower end of the adjustment baffle 50 on the feeder 5. The adjustment of the adjustment baffle 5 shown in FIG. 11 is used to control the stacked number of the semi-manufactures 30. The motion of the feeder 5 is shown in FIGS. 12 to 13 to generate automated production mode.
  • Referring to FIG. 14, the manufacturing method of the present invention comprises the steps of: [0040]
  • (a) sending the material belt [0041] 3 into the punch 2;
  • (b) performing continuous punching in the punch [0042] 2 spaced by an interval of period of shaping by continuous punching;
  • (c) initially shearing the material belt; [0043]
  • (d) shearing the fin side of the material belt with the pressure piece [0044] 26 to form sheet fins;
  • (e) driving the pressure piece to take the sheet fins to move downwards along the connection element (i.e., using the pressure piece to pressurize the fins onto the connection element); and [0045]
  • (f) stacking the sheet fins on the connection element one by one. [0046]
  • Subsequently, the manufacture is taken away, and replacement and positioning of the connection element are performed. The height of the position of the connection element can be adjusted to set the number of stacked fins. The pressure piece is driven in stepping way to recede a small distance each time. The shaping by continuous punching means performing the operations of punching a central hole, shaping of outer appearance, and hole expansion and drawing on the material belt between the top die [0047] 24 and the bottom die 23. After the outer appearance is formed, an action of punching and bending the edge is also included. The bent edge can be used as a separation portion between two sheet fins. More specially, the drawing of hole is exploited to facilitate the whole assembly process.
  • To sum up, in the present invention, the action of continuous punching in a punch is used to form sheet fins, and a connection element is positioned at the rear end thereof. A mobile pressure piece is matched to pressurize the sheet fins onto the connection element one by one. The pressure piece is positioned at a die. A push device and a stepping control device are further matched to achieve the function of orderly stacking so that the sheet fins can be stacked one by one in recession way. Similarly, a feeder can be used to send in the connection elements and the manufactures for adjusting the number of stacked fins. [0048]
  • Although the present invention has been described with reference to the preferred embodiment thereof, it will be understood that the invention is not limited to the details thereof. Various substitutions and modifications have been suggested in the foregoing description, and other will occur to those of ordinary skill in the art. Therefore, all such substitutions and modifications are intended to be embraced within the scope of the invention as defined in the appended claims. [0049]
