Description

  The present invention relates to a temporary assembly device for a heat exchanger core in which a tube through which a cooling medium flows and outer fins that dissipate heat of the cooling medium to air are alternately stacked, and a temporary assembly method thereof.

  Conventionally, as a temporary assembly device for a heat exchanger core, a plurality of tubes are arranged at intervals in the conveying direction, and outer fins are arranged between the adjacent tubes. Using a resiliently deformable guide mechanism having a portion and a plurality of finger members extending integrally therewith, the tube is received in a slot between the finger members so that the tube is not supplied to the first row in a very accurate state. Also known is an arrangement in which an interval between tubes for inserting outer fins is ensured (see, for example, Patent Document 1).

  Hereinafter, embodiments of the present invention will be described in detail based on examples shown in the drawings.

  In the first embodiment, in the manufacturing process of the radiator core (heat exchanger core), as shown in FIG. 1, a plurality of tubes 1 through which the cooling water flows and the heat of the cooling water through these tubes 1 are Used when provisional assembly is performed in a state where a plurality of outer fins 2 that dissipate heat to the air flowing outside are alternately stacked and both ends of the tube 1 are connected to the tank plate 19 of the radiator tank. A temporary assembly apparatus for the heat exchanger core will be described.

  In addition, all the components constituting the heat exchanger core are made of aluminum, and a clad layer made of brazing material is formed on at least one of the joints in each component, and this temporarily assembled heat exchanger core is In the next step, it is transferred to a heat treatment furnace where it is heat-treated and joined together.

First, the whole structure of the temporary assembly apparatus of the heat exchanger core of Example 1 is demonstrated.
As shown in FIG. 1, in the heat exchanger core temporary assembly device of this embodiment, tubes 1 and outer fins 2 are alternately laminated by a tube supply device 4, an outer fin supply device 5 and a reinforcement supply device 6. An unjoined heat exchanger core arrangement set is supplied in which the reinforcement 3 is arranged on the outermost side so as to sandwich them. The temporary assembly device includes a core leveling mechanism 7, an alignment block 8, a first pressing mechanism 9, a second pressing mechanism 10, a tank plate coupling mechanism 11, and a set base 14.

  The tube supply device 4 is a transfer device that supplies the tubes 1 so as to be aligned with an interval in the transfer direction of the tubes 1. For example, a well-known belt conveyor or the like is used.

  The outer fin supply device 5 is a transfer device that sequentially transfers the outer fins 2 shorter in length than the tube 1 toward the tube supply device 3. For example, a well-known transfer worm (for example, WO 2004 / 085111 A1) and the like are used. The outer fins 2 conveyed by the outer fin supply device 5 are moved / arranged between the tubes 1 sequentially conveyed by the tube supply device 4, but this outer fin 2 is moved / arranged. Since a mechanism (for example, a robot with a suction hand or a discharge mechanism) is well known, a specific description and drawings are omitted.

  The reinforcement supply device 6 is a transport device that transports the reinforcement 3 toward the transport conveyor on which the alternately arranged tubes 1 and outer fins 2 are transported. For example, a well-known belt conveyor or the like. Is used. In addition, the reinforce 3 that has been conveyed is moved to the outside of the outermost tube 1 corresponding to one heat exchanger core in which the outer fins 2 are arranged between the tubes 1 by a movement / arrangement mechanism (not shown). Moved / placed. In addition, although the reinforcement 3 conveyed by the reinforcement supply apparatus 6 is moved and arrange | positioned on the both outer sides of the laminated structure of the tube 1 and the outer fin 2 which are conveyed, this reinforcement 3 is moved. Since the arrangement mechanism (for example, a robot with a suction hand) is well known, specific description and drawings are omitted.

  The core leveling mechanism 7 includes tubes 1 and outer fins 2 arranged alternately and sandwiched between reinforcements 3 and 3 in the width direction of a heat exchanger core placed on a base (not shown) (the heat exchanger core is a vehicle). In the direction when mounted on the left and right sides in FIG. 1) from both sides (pressing portions 7 a and 7 a that can be pressed toward the tube 1 of the heat exchanger core). The pressing portions 7a, 7a are flat on the side surface of the tube 1 and in the vertical direction (the direction when the heat exchanger core is mounted on the vehicle and perpendicular to the paper surface of FIG. 1). (Thickness direction) and the longitudinal direction of the tube 1 and the outer fin 2 (the width direction of the heat exchanger core) can be displaced. These displacements are performed using a hydraulic or electric motor. When the pressing parts 7a, 7a are displaced downward, they come to a height that can contact the ends of all the tubes of the heat exchanger core. When the pressing parts 7a, 7a are displaced upward, they interfere with work by other mechanisms. It is set so that it is not in the position.

  The alignment block 8 and the first pressing mechanism 9 constitute a tube pitch matching mechanism. A plurality of the alignment blocks 8 are arranged in the height direction of the heat exchanger core (vertical direction in FIG. 1), and are independently arranged in the width direction of the heat exchanger core and the height direction of the heat exchanger core. It is displaceable and connected by a link 81 shown in FIG. The detailed structure of the alignment block 8 will be described later in detail.

  The first pressing mechanism 9 is a mechanism for pressing the alternately arranged tubes 1 and outer fins 2 on both sides in the height direction of the heat exchanger core, and pressing portions 9a and 9a for pressing the outermost surface of the reinforcement 3 respectively. Have These pressing portions 9a and 9a are driven so as to move in the height direction of the heat exchanger core by a driving portion 9b using hydraulic pressure or an electric motor. Note that one of the pressing portions 9a and 9a is fixed and the other is moved.

The second pressing mechanism 10 presses and presses the tip of the alignment block 8 toward the end of the outer fin 2 from the surface of the alignment block 8 opposite to the heat exchanger core toward the heat exchanger core. The pressing portions 10a and 10a having flat surfaces are provided on both sides in the width direction of the heat exchanger core. These pressing parts 10a and 10a can be driven in the width direction and vertical direction (thickness direction of the heat exchanger core) of the heat exchanger core by the driving part 10b. These drives are driven by hydraulic pressure or an electric motor.
When the alignment block 6 is raised, these are positioned at a height at which the end of the outer inner fin 2 can be pressed and pressed, and when the alignment block 6 is raised, the alignment block 6 does not interfere with the work by other mechanisms. It is supposed to be in

  The tank plate coupling mechanism 11 has a flat pressing portion 11a that presses the inner space side surfaces of the left and right tank plates 12 toward the tube 1 in the axial direction (the width direction of the heat exchanger core). The pressing portion 11a moves by being driven by hydraulic pressure or an electric motor.

  Here, a detailed configuration of the alignment block 8 will be described. As shown in FIG. 2, the alignment block 8 includes a claw portion 8a and a block portion 8b provided integrally therebelow. The nail | claw part 8a is made into the magnitude | size which can be inserted from the downward side of a temporary assembly apparatus between the adjacent tubes 1 which pinch | interpose the outer fin 2. As shown in FIG. Accordingly, the width of the tip of the claw portion 8a (corresponding to the height direction of the heat exchanger core) is formed in a curved shape so as to be narrower than the width H of the main body portion of the claw portion 8a and easily inserted between the tubes 1. It is made into a shape.

The width H of the main body portion of the claw portion 7a is formed to be equal to the tube pitch of the completed heat exchanger core. However, since the claw portion 8a can be inserted between the tubes 1 at the time of temporary pressing to be described later, the width should not be larger than the gap between the tubes 1 at the time of temporary pressing.
Due to the temporary assembly of the heat exchanger, when the reinforcement 3 is pressed on both sides, it moves between the tubes 1 so as to close the gap with the tubes 1 so that the space between the tubes 1 is equal to the tube pitch. It is something to regulate. Therefore, the same number of outer fins 2 between the tubes 1 are provided on both sides of the heat exchanger core.

  In addition, a communication hole 8c is formed in the block portion 8b of the alignment block 8 along the height direction of the heat exchanger core, and a link 13 that can be bent vertically and horizontally penetrates the block 8b. The alignment blocks 8 that can move independently in the lateral direction and the lateral direction are restricted so as not to be scattered and within a predetermined range. When the claw portion 8 a of the alignment block 8 is inserted between the tubes 1, the block portion 8 b is below the tube 1 and is pressed by the second pressing mechanism 10. When the alignment block 8 is pressed by the second pressing mechanism 10, the claw portion 8 a abuts against the end surface of the outer fin 2 and presses them so that the widthwise positions of the outer fin 2 are aligned. The claw portion 8a is set to have a length in the width direction of the heat exchanger core.

  The set stand 14 mounts a heat exchanger core arrangement group in which the tube 1, the outer fin 2, and the reinforcement 3 arranged so as to correspond to the heat exchanger core are arranged in an unjoined state.

Next, the operation of the temporary assembly device for the heat exchanger core according to the first embodiment will be described.
Outer fins 2 conveyed and supplied from the outer fin supply device 5 are inserted between the tubes 1 conveyed and supplied in order from the tube supply device 4, and a plurality of tubes 1 and outer fins 2 are alternately stacked. The reinforcement 3 supplied from the reinforcement supply device 6 is arranged outside the tubes on the outermost side of the stacked tubes 1 and outer fins 2 so as to sandwich them. Thus, although the tube 1, the outer fin 3, and the reinforcement 3 are not yet joined to each other, they constitute a heat exchanger core arrangement set arranged in the same arrangement as the heat exchanger core.

  The unjoined heat exchanger core array set, in which the tube 1, the outer fin 3, and the reinforcement 3 are arranged as described above, is placed on the set base 14 and forms part of the left and right tanks on both side surfaces thereof. The tank plate 12 is attached to the left and right simultaneously as follows.

  That is, first, the first pressing mechanism 9 is operated to move one pressing portion 9a toward the other pressing portion 9a, and the heat exchanger core array set is temporarily moved as shown in FIG. Press. Here, the temporary pressing means pressing to a height that is slightly higher than the height (length in the vertical direction in FIG. 1) of the heat exchanger core array set with the tank plate 12 attached. At the time of this temporary pressing, as is clear from FIG. 3 (a), the positions in the width direction of the ends of the tube 1 and the outer fin 2 are uneven. Moreover, the pressing allowance is set to such an extent that these tubes 1 and outer fins 2 can move in the width direction without excessive force.

Next, the alignment block 8 is lifted by the tube pitch alignment mechanism (the front side in the direction perpendicular to the paper surface of FIG. 1), and the claw portion 8a is adjacent as shown in FIGS. 2 (a) and 3 (a). Insert one each between tubes 1.
At this time, as shown in FIG. 2 (a), the heat exchanger core arrangement set is in a temporarily pressed state, so that a gap is generated between the tube 1 and the claw portion 8a.

  Next, the core leveling mechanism 7 is operated in the above state, the left and right pressing portions 7a, 7a are lowered to both sides of the heat exchanger core arrangement set, and these are moved in the width direction, so that FIG. As shown, the width direction positions of the end portions of the tubes 1 are aligned.

  Next, the pressing force by the second pressing mechanism 10 of the tube pitch alignment mechanism is applied to the block portion 8b of the alignment block 8 to reduce the distance between the alignment blocks 8 on both sides. At this time, as shown in FIG. 3C, the claw portions 8 a of the alignment block 8 press and press both end portions of the outer fin 2 to align the left and right end surfaces of the outer fin 2.

  Next, the first pressing mechanism 9 is operated, and the pressing portions 9a, 9a are further advanced to thereby press the heat exchanger core arrangement set in the height direction. By this main pressing, there is no gap between the claw portion 8a of the alignment block and the tube 1 sandwiching the claw portion 8a, and the state shown in FIG. At this time, since the width H of the claw portion 8a is set to a specified tube pitch, the tubes 1 are aligned at the specified tube pitch.

  Next, the tank plate 12 is supplied to and positioned on both sides of the heat exchanger core arrangement set, and the tank plate coupling mechanism 11 simultaneously presses and moves the left and right tank plates 12 toward both ends of the tube 1 until it hits the alignment block 8. Let During this movement, all the tubes 1 are regulated by the claw portions 8a of the alignment block 8 in accordance with the prescribed tube pitch, so that both ends of the tubes are smooth without galling to the mounting holes 12a of the left and right tank plates 12. Inserted into. As a result, as shown in FIG. 3 (d), there is no gap between the outer fin 2 and the claw portion 8a of the alignment block 8 and the tank plate 12, and the left and right tank plates 12 are arranged in the heat exchanger core arrangement group. It will be assembled.

Next, the alignment block 8 is lowered and removed from between the tubes 1. At this time, the outer fins 2 extend in the longitudinal direction by their own elastic force, and both end portions abut against the left and right tank plates 12. become. Moreover, the pressing part 7a of the core leveling mechanism 7 is also lifted and removed from the heat exchanger core, and the first pressing mechanism 9 also returns the pressing part 9a to its original position.
Then, the heat exchanger core arrangement group to which the tank plate 12 is assembled is taken out from the temporary assembly apparatus and proceeds to the next process.

  In the next step, the outer tank plate is combined with the left and right tank plates 12 and a clad material (a brazing material) is placed at the joint, and heat-treated in a heating furnace to braze the joint to obtain a heat exchanger core. .

As described above, the following effects can be obtained in the temporary assembly apparatus and the temporary assembly method of the heat exchanger according to the first embodiment.
(1) Temporary assembly apparatus and temporary assembly method for heat exchanger according to Embodiment 1 In the temporary assembly apparatus, a plurality of independent alignment blocks 8 are inserted between adjacent tubes 1, 1, respectively. By being pressed in the height direction, the tubes 1 can be aligned in accordance with a prescribed tube pitch.
As a result, when the tank plate 12 and the end portion of the tube 1 are joined, the end portion of the tube 1 rubs against the tank plate 12, resulting in poor connection of the tank plate 12, poor brazing, and airtightness cannot be maintained. It is possible to solve the conventional problems.
In addition, since the tank plate 12 can be simultaneously connected to both ends of the tube 1 from both ends, the number of assembling steps can be reduced.

  (2) Further, since the plurality of alignment blocks 8 are connected to each other by the links 13, even if the alignment blocks 8 can be displaced independently, they are not separated, and the assembling work can be easily performed. Will be able to

  (3) Since the plurality of alignment blocks 8 are connected by the bendable link 13 inserted through the insertion hole 8c formed in the block portion 8b, the displacement of the tube 1 of the alignment block 8 can be simplified. It becomes possible.

  The present invention has been described based on the above embodiments. However, the present invention is not limited to these embodiments, and is included in the present invention even when there is a design change or the like without departing from the gist of the present invention. .

  For example, in the embodiment, a case where a radiator core is temporarily assembled as a heat exchanger core is taken as an example, but a case where a condenser core is temporarily assembled, a case where a radiator core and a capacitor core are close together and temporarily assembled, etc. The present invention can also be applied.

  In the temporary assembly apparatus and the temporary assembly method of the heat exchanger core according to the first embodiment, only one alignment block 8 is interposed between the adjacent tubes 1, but a plurality of alignment blocks 8 may be interposed. good.

  In the core leveling mechanism 7, the pressing portion 7 a is lowered at one end and then moved toward the end portion of the tube 1, but the surface of the pressing portion 7 a on the end portion side of the tube 1 is viewed from below. If the slope is such that the thickness increases toward the top, the end of the tube 1 can be aligned in the width direction simply by lowering the pressing portion 7a.

  In addition, although the said Example demonstrated about the heat exchanger core which has an outer fin, it is possible to apply this invention to the heat exchanger core of an outer finless. In this case, the second pressing mechanism 10 is unnecessary, and the alignment block 8 only needs to be independently displaceable only in the height direction of the heat exchanger, and can be displaced in the width direction of the heat exchanger core. It is not necessary to.
