Description

[Technical field]

[0001] The present invention relates to a plate material processing device. [Background technology]

[0002] A progressive press is known in the art. In a progressive press, a die is provided with a plurality of processing sections. Therefore, a single die for the progressive press can perform processing according to the plurality of processing sections. Furthermore, the progressive press can process the sheet material while flowing the sheet material from the coil body (see, for example, Patent Document 1). Such a die for the progressive press can also be provided with a processing section that can be switched between processing the sheet material and not processing it.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 3-110100 Summary of the Invention [Problem to be solved by the invention]

[0004] The present inventors are considering processing multiple sheet metal materials while they are flowing them through a die, and are considering using a multi-stage die consisting of multiple stages, in which multiple sheet metal materials are supplied between each stage of the multi-stage die and pressed.

[0005] Here, the inventors of the present invention discovered that if a multi-stage mold is provided with a processing section that can be switched between processing and not processing the plate material, the pass line cannot be horizontalized within the multi-stage mold, resulting in a misalignment, and the plate material may be cut between adjacent processing sections or may take on an unintended shape.

[0006] FIG. 22 is a schematic diagram showing a case where no processing is performed in the specific processing section of the multi-stage die, where (a) shows the state before pressing, and (b) shows the pressed state. As shown in FIG. 22(a), the pass line PL of the sheet materials 11α and 11β is kept horizontal before pressing. When the sheet material is not processed in the specific processing section as shown in FIG. 22(b), the thickness is adjusted by the striker ST. Here, the horizontality of the pass line PL is maintained for the sheet material 11α in the first row from the bottom. However, for the sheet material 11β in the second row from the bottom, the pass line PL becomes inclined due to the positional relationship of the second layer die of the multi-stage die. In this way, when a multi-stage die is used, a new problem occurs in terms of the horizontality of the pass line PL in the die.

[0007] The present invention has been made to solve such problems, and its object is to provide a plate material processing device that can improve the horizontality of the pass line within a multi-stage die. [Means for solving the problem]

[0008] The plate material processing device according to the present invention comprises a supply means for continuously supplying N long plate materials (N is an integer of 2 or more), a multi-stage die having (N+1) stages for processing the N plate materials supplied by the supply means, and a drive means for generating a press operation on the multi-stage die, wherein the multi-stage die has a first processing section for performing a first processing on the N plate materials, and a second processing section adjacent to the first processing section for performing a second processing on at least some of the N plate materials, wherein the first processing section generates a press stroke in the multi-stage die each time a press operation is generated by the drive means, thereby performing the first processing on at least some of the N plate materials, and the second processing section is capable of transitioning between a state in which the press stroke is generated in the multi-stage die each time a press operation is generated by the drive means, thereby performing the second processing on at least some of the N plate materials, and a state in which the press stroke is generated but the second processing is not performed. Effect of the Invention

[0009] According to the present invention, it is possible to provide a plate material processing device capable of improving the horizontality of a pass line in a multi-stage die. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] The present invention will be described below along with preferred embodiments. Note that the present invention is not limited to the embodiments shown below, and can be modified as appropriate within the scope of the present invention. In addition, in the embodiments shown below, some configurations are omitted from illustration and description, but it goes without saying that publicly known or well-known technologies are appropriately applied to the details of the omitted technologies within the scope of no contradiction with the contents described below.

[0012] Figures 1 and 2 are diagrams showing the configuration of a heat-insulating panel manufactured using the plate processing device according to the first embodiment, with Figure 1 showing a perspective view and Figure 2 showing a cross-sectional view. The heat-insulating panel 1 shown in Figures 1 and 2 is configured to include two air-conditioning panels 10, a heat insulator 20, and a flow path 30.

[0013] The air conditioning panel 10 is formed by processing two plates 11 to form an internal space IS, and is configured by welding edges 12. The internal space IS is, for example, vacuumed to be in a reduced pressure state. The air conditioning panel 10 is a large structure with a long side of at least 60 cm or more. Each of the two plates 11 is configured with a thickness of 0.8 mm or less, and the air conditioning panel 10 is lightweight. In the following, a large air conditioning panel 10 having a side of 60 cm or more is assumed for explanation, but this is not limited to this, and the air conditioning panel 10 may be applied to one with a long side of less than 60 cm. The thickness of the plate 11 may also be more than 0.8 mm. In the following, the air conditioning panel 10 is assumed to have a long side of at least 60 cm or more and a plate 11 with a thickness of 0.8 mm or less.

[0014] In such an air-conditioning panel 10, as shown in Figs. 1 and 2, a large number of protrusions 13 are formed on both plate materials 11. The large number of protrusions 13 are formed on the two plate materials 11 facing each other, and the tops of the protrusions 13 are in contact with each other. Therefore, the two plate materials 11 are separated in the internal space IS by the height of two protrusions 13. In addition, by the tops of the protrusions 13 contacting each other, the air-conditioning panel 10 in which the internal space IS is evacuated becomes more resistant to external pressure. Note that, although 32 protrusions 13 are formed in Figs. 1 and 2, in reality, since the plate materials 11 of the air-conditioning panel 10 are thin and have a large structure, a larger number of protrusions 13 are formed. Specifically, in an air-conditioning panel 10 having a width of 930 mm and a length of 2000 mm, for example, several thousand protrusions 13 are formed on each plate material 11.

[0015] In addition, in this embodiment, the air conditioning panel 10 has a large number of protrusions 13 formed on both of the two plate materials 11, but this is not limited to the above, and a large number of protrusions 13 may be formed on only one of the plate materials 11, and the other plate material 11 may be a flat plate.

[0016] The two air conditioning panels 10 are configured so that a refrigerant flows through two flow paths 30. The two air conditioning panels 10 are configured so that heat from one air conditioning panel 10 can be dissipated from the other air conditioning panel 10 through the flow of the refrigerant. In addition, a heat insulator 20 is provided between the two air conditioning panels 10 to ensure thermal insulation. For this reason, the heat insulated panel 1 prevents heat from the other side from flowing through to one side by the heat insulator 20, and allows heat from one side to flow through to the other side through the refrigerant circulation.

[0017] When such heat transfer is performed, one of the two air conditioning panels 10 functions as an evaporator E, and the other functions as a condenser C. More specifically, the liquid refrigerant evaporates in the evaporator E due to heat from one side. As a result, the space S1 side facing the air conditioning panel 10 on one side is cooled by absorbing the heat of evaporation. Meanwhile, the evaporated refrigerant, that is, the vapor refrigerant, reaches the condenser C through the first flow path 31. In the condenser C, the vapor refrigerant is liquefied by the heat from the space S2 side facing the air conditioning panel 10 on the other side, and becomes a liquid refrigerant. The condensation heat generated when the vapor refrigerant liquefies is discarded to the space S2 side. Also, the liquefied liquid refrigerant reaches the evaporator E again through the second flow path 32. As described above, the heat insulating panel 1 allows heat from one side to pass through to the other side.

[0018] Here, in order to promote evaporation of the liquid refrigerant at least in the air conditioning panel 10 on the evaporator E side, a wick layer 14 is formed on at least one plate material 11 (the plate material 11 on the side farther from the condenser C). The wick layer 14 sucks up and holds the liquid refrigerant stored on the lower side of the evaporator E by capillary action. This wick layer 14 allows the evaporation area of ​​the evaporator E to expand in the height direction, enabling efficient evaporation in the height direction.

[0019] Here, the air conditioning panel 10 according to this embodiment has a large structure. Therefore, if the protrusions 13 are not welded to the mating plate material 11 (protrusions 13), the tops of the protrusions 13 will be misaligned, causing the air conditioning panel 10 to bend. As a result, it is difficult to use the air conditioning panel 10 for elevations, etc., and it is also difficult to use the air conditioning panel 10 as a building material.

[0020] Therefore, in the air conditioning panel 10 according to this embodiment, the tops of many of the protrusions 13 are welded together. Here, a wick layer 14 is formed on the air conditioning panel 10 on the evaporator E side, but in the air conditioning panel 10 according to this embodiment, the wick layer 14 is formed so as to avoid the tops of the protrusions 13.

[0021] FIG. 3 is a cross-sectional view showing another example of the insulation panel 1 according to the first embodiment. The insulation panel 1 may be one that is long in one direction, for example, by connecting the panels shown in FIG. 1 and FIG. 2. Here, the air conditioning panel 10 needs to be divided into sections of a predetermined size in order to circulate the refrigerant. Therefore, in order to manufacture a long insulation panel 1, the air conditioning panel 10 needs to be divided into sections of a certain size and welded. Such welded parts are called compartment forming parts 15. By dividing the insulation panel 1 into sections of a certain size using the compartment forming parts 15, it is possible to make the insulation panel 1 long in one direction while still allowing the circulation of the refrigerant. The compartment forming parts 15 are also formed in the insulation panel 1 shown in FIG. 1 and FIG. 2.

[0022] As described above, in order to manufacture the heat insulating panel 1 (air conditioning panel 10), it is necessary to carry out processes such as forming the numerous protrusions 13 and forming the compartment forming portions 15. From the viewpoint of manufacturability, it is preferable to carry out the processing by using a mold having multiple layers while flowing N (N is an integer of 2 or more) sheets of plate material 11.

[0023] The plate material processing device that performs such processing will be described below. Fig. 4 is a configuration diagram showing the plate material processing device according to the first embodiment. As shown in Fig. 4, the plate material processing device is configured to include a plate material supply section (supply means) 100, a multi-stage die 200, a drive section (drive means) 300 that performs a press operation to generate a press stroke in the multi-stage die 200, and a synchronous movement section (synchronous movement means) 400.

[0024] The plate material supplying section 100 shown in FIG. 4 is configured to have, for example, N (four) uncoilers. The coil body wound around the N uncoilers constitutes a long plate material 11. The N plate materials 11 are continuously supplied as being unwound from the uncoilers. In particular, the long plate material 11 supplied from the plate material supplying section 100 has a thickness of 0.8 mm or less. Note that, although the plate material supplying section 100 has four uncoilers, the present invention is not limited to this and it is sufficient that the plate material supplying section 100 has two or more uncoilers.

[0025] The multi-stage die 200 processes N sheets of plate material 11 supplied by the plate material supply unit 100. FIG. 5 is a perspective view showing an example of the multi-stage die 200 shown in FIG. 4, where (a) shows a first state and (b) shows a second state. FIG. 6 is a schematic cross-sectional view showing an example of the multi-stage die 200 shown in FIG. 4, where (a) shows a state before pressing in the first state and (b) shows a state during pressing in the first state. FIG. 7 is a schematic cross-sectional view showing an example of the multi-stage die 200 shown in FIG. 4, where (a) shows a state before pressing in the second state and (b) shows a state during pressing in the second state.

[0026] 5 to 7, the multi-stage die 200 has a structure having (N+1) stages for machining N plate materials 11. In the following description, it is assumed that N is "4."

[0027] The five-stage multi-stage mold 200 is provided in the following order from the bottom: a first layer mold 201, a second layer mold 202, a third layer mold 203, a fourth layer mold 204, and a fifth layer mold 205. A first plate material 11a is supplied between the first layer mold 201 and the second layer mold 202, and a second plate material 11b is supplied between the second layer mold 202 and the third layer mold 203. A third plate material 11c is supplied between the third layer mold 203 and the fourth layer mold 204, and a fourth plate material 11d is supplied between the fourth layer mold 204 and the fifth layer mold 205.

[0028] Here, as shown in Fig. 6 and Fig. 7, the multi-stage mold 200 includes a first processing section 210 that performs embossing (first processing) on ​​four plate materials 11, a second processing section 220 that is adjacent to the first processing section 210 and performs trapezoid processing (second processing) on ​​at least a part of the N plate materials 11, and a shifting mechanism 230. More specifically, the supply side (hereinafter simply referred to as the supply side) of the plate materials 11 among the first to fifth layer molds 201 to 205 constitutes the first processing section 210, and the discharge side (hereinafter simply referred to as the discharge side) of the plate materials 11 constitutes the second processing section 220. Furthermore, the third layer mold 203 has a lower mold 203a, an upper mold 203b, and a fixed mold 203c. In the above, "adjacent" means that they are adjacent to each other without any other processing section intervening therebetween.

[0029] The shift mechanism 230 includes a wedge-shaped striker 231 and an air cylinder 232. The second processing section 220 shifts between a state in which the second processing is performed on at least some of the four plate materials 11 and a state in which the second processing is not performed on at least some of the four plate materials 11 by shifting the state (the positions of the lower die 203a and the upper die 203b) using the shift mechanism 230. Hereinafter, the multi-stage die 200 will be described in detail with reference to Figs. 8 and 9 in addition to Figs. 5 to 7.

[0030] 8 and 9 are perspective views showing the details of the multi-stage die 200, in which Fig. 8(a) shows the first die 201, Fig. 8(b) shows the second die 202, Fig. 8(c) shows the lower die 203a, and Fig. 8(d) shows the wedge-shaped striker 231. Also, Fig. 9(a) shows the upper die 203b, Fig. 9(b) shows the third die 203, and Fig. 9(c) shows the fourth die 204.

[0031] First, the first processing section 210 will be described. The first processing section 210 is for forming a large number of protrusions 13. Specifically, as shown in Fig. 6, Fig. 7, and Fig. 8(a), the first layer mold 201 has a protrusion row 211a on the upper supply side for forming a large number of protrusions 13 in the first plate material 11a. Also, as shown in Fig. 6, Fig. 7, and Fig. 9(b), the lower and upper surfaces of the fixed mold 203c located on the supply side of the third mold 203, and the lower surface of the supply side of the fifth mold 205 have similar protrusion rows 213a1, 231a2, and 215a formed thereon.

[0032] 6 and 7, the second layer mold 202 has a recessed portion row 212b1 on the supply side of its lower surface that matches the shape of the protruding portion row 211a of the first layer mold 211. Also, as shown in Figures 6, 7, 8(b) and 9(c), similar recessed portion rows 212b2, 214b1, and 214b2 are formed on the upper surface of the supply side of the second mold 202 and the lower and upper surfaces of the supply side of the fourth mold 204.

[0033] Due to this configuration, the first processing unit 210 performs embossing to form a large number of protrusions 13 on the four plate materials 11 by generating a press stroke at each stage (the first layer die 201 is fixed, so the second to fifth layer dies 202 to 205: the same applies below) each time a press operation is performed by the drive unit 300.

[0034] Next, the second processing section 220 will be described. The second processing section 220 is for forming a trapezoidal portion that becomes the partition forming portion 15. Specifically, as shown in Fig. 6, Fig. 7, and Fig. 9(a)(b), the upper mold 203b of the third layer mold 203 has a trapezoidal protrusion 223a2 extending in the width direction on the upper surface. Also, as shown in Fig. 6 and Fig. 7, the upper mold 203b of the third layer mold 203 has a similar trapezoidal protrusion 223a1 on the lower surface.

[0035] 6, 7, and 8(b), the second layer mold 202 has a trapezoidal recess 222b on the discharge side of the upper surface that matches the shape of the trapezoidal protrusion 223a1. Also, as shown in FIGS. 6 and 7, the fourth layer mold 204 has a similar trapezoidal recess 224b formed on the discharge side of the lower surface.

[0036] Due to this configuration, the second processing section 220 generates a press stroke at each stage every time a pressing operation is performed by the driving section 300, and forms trapezoidal portions in the second and third plate materials 11b, 11c for forming welded portions that become the compartment forming portions 15. Note that, although both plate materials 11 in the air conditioning panel 10 shown in Figures 1 to 3 are processed into a trapezoid shape, only one of the plate materials 11 may be processed into a trapezoid shape as shown in Figures 5 to 9.

[0037] As shown in Fig. 9(c), the fourth layer mold 204 has a number of groove-shaped retreat sections 214c on the discharge side of the upper surface. Because the fourth layer mold 204 has this retreat section 214c, the number of protrusions 13 formed on the fourth plate material 11d on the supply side can pass through without being crushed. As shown in Figs. 6 and 7, a similar retreat section 212c is also formed on the discharge side of the lower surface of the second layer mold 202. Therefore, the number of protrusions 13 formed on the first plate material 11a can also pass through without being crushed.

[0038] 6, 7, and 8(c), the upper surface of the lower mold 203a of the third layer mold 203 is an inclined surface that faces slightly downward toward the discharge side. Similarly, as shown in Fig. 6, 7, and 9(a), the lower surface of the upper mold 203b of the third layer mold 203 is an inclined surface that faces slightly upward toward the discharge side.

[0039] Furthermore, the wedge-shaped striker 231 has a shape that matches this inclined surface. Also, the air cylinder 232 uses air to move the wedge-shaped striker 231 to the supply side or the discharge side.

[0040] When the air cylinder 232 moves the wedge-shaped striker 231 to the supply side, the lower die 203a of the third layer die 203 moves slightly downward, and the upper die 203b of the third layer die 203 moves slightly upward. As a result, the trapezoidal convex portions 223a1, 223a2 are in a protruding state, and when a press stroke occurs due to the pressing operation of the driving unit 300, trapezoidal portions are formed in the second and third plate materials 11b, 11c. This state is the first state shown in Figures 5(a) and 6.

[0041] On the other hand, when the air cylinder 232 moves the wedge-shaped striker 231 to the discharge side, the lower die 203a of the third layer die 203 moves slightly upward, and the upper die 203b of the third layer die 203 moves slightly downward. As a result, the trapezoidal convex portions 223a1, 223a2 are in a retracted state, and even if a press stroke is generated by the pressing operation of the driving unit 300, no trapezoidal portions are formed in the second and third plate materials 11b, 11c. This state is the second state shown in Figures 5(b) and 7.

[0042] The multi-stage mold 200 also performs Z-folding at the side. As shown in FIG. 1, the air conditioning panel 10 has a Z-folded portion 16 formed at the side, and the multi-stage mold 200 also performs Z-folding to form the Z-folded portion 16. In detail, as shown in FIG. 8(b), the second layer mold 202 is formed with a protruding step 212d for protruding the entire recessed portion row 212b2 toward the third layer mold 203. The protruding step 212d is formed at both ends of the recessed portion row 212b2 in the width direction. Although not shown, the third layer mold 203 also has a retracting step formed at a position corresponding to the recessed portion row 212b2 for retracting the entire protruding portion row 213a1.

[0043] 9(b), the third layer mold 203 is formed with retracting steps 213d for retracting the entire convex portion row 213a2 toward the second layer mold 202. The retracting steps 213d are formed at both ends of the convex portion row 213a2 in the width direction. Although not shown, the fourth layer mold 204 is also formed with protruding steps at positions corresponding to the convex portion row 213a2 for protruding the entire concave portion row 214b1.

[0044] Since the multi-stage mold 200 includes the protruding step portion 212d and the recessed step portion 213d, the Z-folded portion 16 can be formed in addition to the formation of the multiple protrusions 13.

[0045] The synchronous movement unit 400 shown in Fig. 4 reciprocates the multi-stage die 200 along the conveying direction. This synchronous movement unit 400 moves the multi-stage die 200 in synchronization with the conveying speed of the plate material 11 when the plate material 11 moves in the conveying direction. The multi-stage die 200 performs press working while being moved in synchronization with the conveying speed of the plate material 11. This allows the multi-stage die 200 to press the plate material 11 that is being conveyed continuously without having to convey the plate material 11 in a frame-by-frame manner, thereby further improving manufacturability.

[0046] Next, the operation of the plate material processing device according to this embodiment will be described. First, the plate material supply unit 100 continuously supplies four plates 11 to the multi-stage die 200 by feeding them from the four uncoilers. Next, the plate material processing device controls the air cylinder 232 to move the wedge-shaped striker 231 to the supply side to set the multi-stage die 200 in the first state. In addition, in this first state, the plate material processing device generates a pressing operation by the drive unit 300 to generate a pressing stroke in each stage of the multi-stage die 200. As a result, the first processing unit 210 forms a large number of convex portions 13 in the first to fourth plates 11a to 11d, and the second processing unit 220 forms trapezoidal portions in the second and third plates 11b, 11c.

[0047] Then, the plate material processing device controls the air cylinder 232 to move the wedge-shaped striker 231 to the discharge side to bring the multi-stage die 200 into the second state. In addition, in this second state, the plate material processing device generates a pressing operation by the drive unit 300 to generate a press stroke in each stage of the multi-stage die 200. As a result, the first processing unit 210 forms a large number of protrusions 13 in the first to fourth plate materials 11a to 11d. In addition, in the second state, the second processing unit 220 does not form trapezoidal portions in the second and third plate materials 11b and 11c because the trapezoidal protrusions 223a1 and 223a2 are in the retracted state.

[0048] Thereafter, the plate material processing device generates a pressing operation by the driving unit 300 in sequence while remaining in the second state, and forms a large number of protrusions 13 at a predetermined pitch on the first to fourth plate materials 11a to 11d. Next, when the plate material 11 is transported a predetermined length, the plate material processing device controls the air cylinder 232 again to set the multi-stage die 200 to the first state. Then, the plate material processing device generates a pressing operation by the driving unit 300 while in the first state, and forms a large number of protrusions 13 and trapezoidal portions. Thereafter, the above operations are repeated. During this process, the plate material processing device controls the synchronous moving unit 400 to transport the plate material 11 while performing press processing.

[0049] In this way, the plate material processing device according to this embodiment generates a press stroke in the first processing section 210 and the second processing section 220 (preferably generates a press stroke in which the stroke amount of each stage is the same in the first processing section 210 and the second processing section 220). In particular, the plate material processing device generates a press stroke in the second processing section 220 whether the multi-stage die 200 is in the first state or the second state (preferably generates a press stroke in which the stroke amount of each stage is the same in the first state and the second state). Here, as shown in FIG. 22, when there is no need for specific processing on the plate material, if a press stroke is generated in the adjacent processing section and a press stroke is not generated in the specific processing section, the horizontality of the pass line PL cannot be maintained. However, the plate material processing device according to this embodiment does not generate such a difference and can improve the horizontality of the pass line PL.

[0050] In this way, according to the plate material processing device according to the first embodiment, the second processing unit 220 can be changed between a state in which trapezoid processing is performed and a state in which trapezoid processing is not performed, and each time a pressing operation is performed by the driving unit 300, a press stroke is performed on each stage of the multi-stage die 200 in the same manner as the first processing unit 210. Therefore, even when trapezoid processing is not required, a press stroke is generated in the second processing unit 220 in the same manner as the first processing unit 210, and the pass line PL is horizontalized even if the first processing unit 210 and the second processing unit 220 are adjacent to each other. Therefore, a plate material processing device capable of improving the horizontality of the pass line PL in the multi-stage die 200 can be provided.

[0051] Next, a second embodiment will be described. The plate material processing device according to the second embodiment is similar to that of the first embodiment, but some configurations are different. The following description will focus on the differences from the first embodiment.

[0052] Fig. 10 is a configuration diagram showing a plate material processing device according to a second embodiment. As shown in Fig. 10, the plate material processing device further includes a distance adjustment section (distance adjustment means) 500. The multi-stage die 600 is configured to include a first processing section 610, a second processing section 620, and a shifting mechanism 630, as well as a connecting member 640. The distance adjustment section 500 adjusts the distance between the first processing section 610 and the second processing section 620. The connecting member 640 is a member that connects the first processing section 610 and the second processing section 620.

[0053] Furthermore, in the second embodiment, the shift mechanism 630 is configured to shift the second processing unit 620 between a first state in which trapezoid processing is performed and a second state in which trapezoid processing is not performed, using a mechanical mechanism. In other words, the configuration does not include an electrical means using air pressure, such as the air cylinder 232. In addition, the shift mechanism 630 shifts between the first state in which trapezoid processing is performed and the second state in which trapezoid processing is not performed by the action of the connection member 640 through the adjustment of the distance by the distance adjustment unit 500. This will be described in detail below.

[0054] Fig. 11 is a schematic cross-sectional view showing an example of the multi-stage die 600 shown in Fig. 10. Fig. 11(a) shows a state before pressing in a first state, and Fig. 11(b) shows a part of (a). Fig. 11(c) shows a state during pressing in the first state, and Fig. 11(d) shows a part of (c). Fig. 12 is a perspective view showing an example of the multi-stage die 600 shown in Fig. 10.

[0055] 11 and 12, the multi-stage die 600 has a five-stage configuration similar to the first embodiment, but the first processing unit 610 is a first die set, and the second processing unit 620 is a second die set, which are configured to be spaced apart from each other. The first processing unit 610 and the second processing unit 620 simultaneously generate a press stroke by the pressing operation of the driving unit 300.

[0056] The first processing unit 610 is located on the discharge side of the second processing unit 620. Convex portion rows 611a, 613a1, 613a2, and 615a for forming a large number of convex portions 13 are formed on the upper surface of a first layer mold 611 of the first processing unit 610, the lower surface and upper surface of a third layer mold 613, and the lower surface of a fifth layer mold 615, respectively.

[0057] In addition, the first processing portion 610 has recess rows 612b1, 612b2, 614b1, and 614b2 formed on the lower and upper surfaces of the second layer mold 612, which are positioned opposite the protrusion rows 611a, 613a1, 613a2, and 615a, and on the lower and upper surfaces of the fourth layer mold 614, which match the shapes of the protrusion rows 611a, 613a1, 613a2, and 615a.

[0058] Therefore, the first processing unit 610 performs embossing to form a large number of protrusions 13 on the four plate materials 11 by generating a press stroke at each stage every time the driving unit 300 generates a press operation.

[0059] Furthermore, the third layer die 623 of the second processing section 620 is equipped with a rotating shaft 623a and a cam pin 623b. Moreover, the connecting member 640 is a plate material having one end on the discharge side fixedly attached to the third layer die 613 of the first processing section 610. This connecting member 640 is formed with a long hole 641 extending in the conveying direction of the plate material 11 and a cam groove 642 curved upward with respect to the conveying direction.

[0060] In the second embodiment, the third layer mold 623 is rotatable about the rotation shaft 623a with the rotation shaft 623a fitted in the long hole 641 of the connection member 640. Furthermore, the cam pin 623b of the third layer mold 623 is fitted in the cam groove 642. The third layer mold 623 is formed into a substantially octagonal shape in cross section, and trapezoidal convex portions 623c1, 623c2 are formed on two opposing surfaces. All other surfaces of the third layer mold 623 are flat.

[0061] When the distance between the first processing unit 610 and the second processing unit 620 is shortened by the distance adjustment unit 500, the trapezoidal convex portions 623c1, 623c2 of the third layer mold 623 are oriented in the vertical direction by a cam mechanism formed by the cam groove 642 and the cam pin 623b. Also, trapezoidal concave portions 622d, 624d are formed on the upper surface of the second layer mold 622 and the lower surface of the fourth layer mold 624. Therefore, in this state (first state), the second processing unit 620 performs trapezoidal processing on the second and third plate materials 11b, 11c by generating a press stroke in each stage every time a pressing operation is generated by the drive unit 300.

[0062] On the other hand, when the distance between the first processing unit 610 and the second processing unit 620 is lengthened by the distance adjustment unit 500, the trapezoidal convex portions 623c1, 623c2 of the third layer mold 623 are oriented in the conveying direction by the cam mechanism formed by the cam groove 642 and the cam pin 623b. Therefore, the second processing unit 620 generates a press stroke in each stage every time a pressing operation is generated by the drive unit 300, but is in a second state in which trapezoidal processing is not performed on the second and third plate materials 11b, 11c.

[0063] In the second embodiment, the upper surface of the first layer mold 621, the lower surface of the second layer mold 622, the upper surface of the fourth layer mold 624, and the lower surface of the fifth layer mold 625 are flat without any protrusions etc. Therefore, although these do not apply press working to the plate material 11, a press stroke is generated to perform flat striking.

[0064] FIG. 13 is a perspective view showing the details of the synchronous moving part 400 and the distance adjusting part 500 shown in FIG. 10. As shown in FIG. 13, in the second embodiment, the synchronous moving part 400 and the distance adjusting part 500 are integrally configured. First, the distance adjusting part 500 includes a straight gear part 510 extending in the conveying direction of the plate material 11, a worm gear (rotation passive part) 520 whose teeth match with the straight gear part 510, and a motor part (rotation driving part) 530 that rotates and drives the worm gear 520. The worm gear 520 includes a connecting part 521 connected to the second processing part 620. In addition, the worm gear 520 has a ball spline structure in its rotating shaft 522. Therefore, the motor part 530 and the worm gear 520 are connected to each other so as to be capable of transmitting rotation and slidably moving linearly.

[0065] Further, the straight gear portion 510 includes a connecting portion 511 connected to the first processing portion 610. Therefore, when the motor portion 530 rotates the worm gear 520, the worm gear 520 moves on the straight gear portion 510. Here, since the first processing portion 610 is connected to the straight gear portion 510 and the second processing portion 620 is connected to the worm gear 520, the distance between the first processing portion 610 and the second processing portion 620 is adjusted by the worm gear 520 moving on the straight gear portion 510.

[0066] Further, the synchronous moving unit 400 includes a pinion gear 410 whose teeth mesh with the straight gear portion 510, and a motor unit 420 that rotates and drives the pinion gear 410. Therefore, when the motor unit 420 rotates and drives the pinion gear 410, the straight gear portion 510 functions as a so-called rack gear, and changes its position. Therefore, the synchronous moving unit 400 can move both the first processing unit 610 connected to the straight gear portion 510 and the second processing unit 620 connected to the straight gear portion 510 via the worm gear 520 by the motor unit 420 rotating and driving the pinion gear 410. Then, the synchronous moving unit 400 moves both of them in accordance with the conveying speed of the plate material 11, so that the plate material processing device can perform press processing while conveying the plate material 11. This allows the plate material processing device to perform press working on the plate material 11 that is continuously conveyed, without having to convey the plate material 11 in a frame-by-frame manner, thereby further improving manufacturability.

[0067] The synchronous movement unit 400 and the distance adjustment unit 500 are not limited to the configuration shown in Fig. 13. For example, the rotation shaft 522 may be configured by a spline shaft, so that it can transmit rotation and slide linearly. In this case, the worm gear 520 has an inner surface that matches the shape of the spline shaft.

[0068] Also, two bevel gears and a spur gear may be used instead of the worm gear 520. In this case, the first bevel gear is configured to be linearly slidable and rotated by the motor unit 530. The second bevel gear is meshed with the first bevel gear at an angle of 90° and rotates with the rotation of the first bevel gear. The spur gear is attached to the second bevel gear so as to rotate in the same manner as the second bevel gear. Also, the spur gear is meshed with the straight gear 510.

[0069] Further, the synchronous movement unit 400 is equipped with a pinion gear 410 and a motor unit 420, but may instead be configured with a cylinder (such as a linear servo cylinder, an air cylinder, or a hydraulic cylinder) that moves the linear gear unit 510 in its linear direction.

[0070] Also, a ball screw may be used instead of the linear gear unit 510, and the screw shaft may be moved linearly in the axial direction by rotating the nut. In this case, a first ball nut connected to the first processing unit 610 and a second ball nut connected to the second processing unit 620 are attached to the ball screw. The motor unit 420 directly rotates the ball screw. As a result, the first ball nut and the second ball nut move simultaneously. Meanwhile, a rotational force is applied to the first ball nut by the motor unit 530. Specifically, a pulley that rotates while sliding linearly by the motor unit 530 is provided instead of the worm gear 520, and a belt is wound around the pulley and the first ball nut. As a result, only the first ball nut can be moved relative to the ball screw by driving the motor unit 530.

[0071] Furthermore, a first spur gear capable of sliding linearly may be used in place of the pulley, and a second spur gear may be provided on the first ball nut so that these spur gears mesh with each other, thereby eliminating the need for a belt.

[0072] In addition, a ball screw spline structure combining a ball spline structure and a ball screw may be used. In this case, a motor unit or the like for driving the ball screw nut of the ball screw spline may be provided instead of the pinion gear 410 and the motor unit 420 of the synchronous movement unit 400, and the ball screw spline may be synchronously moved instead of the linear gear unit 510, and a spline outer cylinder capable of linear sliding relative to the spline outer cylinder may be provided instead of the worm gear 520, and a motor unit for driving the spline outer cylinder may be provided instead of the motor unit 530.

[0073] Next, the operation of the plate material processing device according to this embodiment will be described. First, the plate material supplying unit 100 continuously supplies four plates to the multi-stage die 600 by feeding the plate material 11 from the four uncoilers. Next, the plate material processing device controls the distance adjusting unit 500 to shorten the distance between the first processing unit 610 and the second processing unit 620. This causes the third layer die 623 of the second processing unit 620 to rotate so that the trapezoidal convex parts 623c1 and 623c2 face in the up-down direction. This causes the plate material processing device to put the multi-stage die 600 into the first state.

[0074] In this first state, the plate material processing device generates a pressing operation by the driving unit 300, generating a pressing stroke in each stage of the multi-stage die 600. As a result, the first processing unit 610 forms a large number of convex portions 13 in the first to fourth plate materials 11a to 11d, and the second processing unit 620 forms trapezoidal portions in the second and third plate materials 11b, 11c.

[0075] Thereafter, the plate material processing device controls the distance adjustment unit 500 to increase the distance between the first processing unit 610 and the second processing unit 620. As a result, the third layer die 623 of the second processing unit 620 is rotated so that the trapezoidal convex portions 623c1, 623c2 face the conveying direction, and the plate material processing device sets the multi-stage die 600 to the second state.

[0076] In addition, in this second state, the plate material processing device generates a pressing operation by the driving unit 300, and generates a press stroke in each stage of the multi-stage die 200. As a result, the first processing unit 210 forms a large number of convex portions 13 in the first to fourth plate materials 11a to 11d. In addition, in the second state, the second processing unit 220 generates a press stroke in each stage, but does not form trapezoidal portions in the second and third plate materials 11b, 11c.

[0077] Thereafter, the plate material processing device generates press operations sequentially by the drive unit 300 while remaining in the second state, and forms a large number of convex portions 13 at a predetermined pitch on the first to fourth plate materials 11a to 11d. Next, when the plate material 11 is transported a predetermined length, the plate material processing device controls the distance adjustment unit 500 again to set the multi-stage die 600 to the first state. Then, the plate material processing device generates press operations by the drive unit 300 while in the first state, and forms a large number of convex portions 13 and trapezoidal portions. Thereafter, the above operations are repeated. During this process, the plate material processing device controls the synchronous movement unit 400 to transport the plate material 11 while performing press processing.

[0078] Here, the plate material processing device according to the second embodiment also generates a press stroke in the first processing section 210 and the second processing section 220. In particular, the second processing section 220 generates a press stroke whether the multi-stage die 200 is in the first state or the second state. Therefore, a processing section where a press stroke occurs and a processing section where a press stroke does not occur are not adjacent to each other, and the horizontality of the pass line PL can be improved.

[0079] In this way, according to the sheet metal processing apparatus of the second embodiment, as in the first embodiment, it is possible to provide a sheet metal processing apparatus that can improve the horizontality of the pass line PL within the multi-stage die 600.

[0080] According to the second embodiment, the connection member 640 acts by adjusting the distance between the first processing unit 610 and the second processing unit 620 to transition between a state in which trapezoid processing is performed and a state in which trapezoid processing is not performed. Here, the distance adjustment unit 500 only needs to operate the entire first processing unit 610 and the second processing unit 620, for example, so that it is possible to arrange the first processing unit 610 and the second processing unit 620 near the lower end, etc., which is less susceptible to vibration. On the other hand, the connection member 640 and the transition mechanism 630 are arranged to be easily affected by vibration, but they are composed of mechanical mechanisms, and compared to the case of using electrical means requiring electrical wiring, etc., it is possible to make the state transition between a state in which the second processing is performed and a state in which it is not performed resistant to vibration. Therefore, it is possible to provide a plate processing device that can be made relatively resistant to vibration in state transition.

[0081] Here, when adjusting the distance between the first machining unit 610 and the second machining unit 620 and synchronizing them with the sheet material speed, it is also possible to separate the first machining unit 610 and the second machining unit 620 and operate them separately. However, in this case, it is necessary to control the distance between the two while synchronizing them with the sheet material speed, and it is difficult to control the two well simultaneously. Therefore, the synchronization with the sheet material speed is controlled by operating the entire multi-stage die 600 by the synchronous moving unit 400, and the distance between the two is controlled by the distance adjusting unit 500, so that these can be simplified. Furthermore, when such a configuration is adopted, the motor unit 530 of the distance adjusting unit 500 slides linearly relative to the worm gear 520, so that it can be fixed without being moved by the operation of the synchronous moving unit 400, and reliability can be improved so as to prevent early failures, etc.

[0082] Next, a third embodiment will be described. The plate material processing device according to the third embodiment is similar to that of the second embodiment, but some configurations are different. The following description will focus on the differences from the second embodiment.

[0083] Fig. 14 is a schematic cross-sectional view showing the configuration of the multi-stage die of the plate processing device according to the third embodiment, where (a) shows the first state and (b) shows the second state. As shown in Fig. 14, the multi-stage die 700 according to the third embodiment also has a first processing unit 710 and a second processing unit 720 in a separated state, and each is configured with a first layer die 711, 721, a second layer die 712, 722, a third layer die 713, 723, a fourth layer die 714, 724, and a fifth layer die 715, 725. In addition, the synchronous movement unit 400 and the distance adjustment unit 500 are the same as those in the second embodiment.

[0084] The third layer mold 723 of the second processing unit 720 includes a lower mold 723a, an upper mold 723b, and a fixed mold 723c. In addition, one end of the connection member 740 on the discharge side is attached to the third layer mold 713 of the first processing unit 710, and the other end side on the supply side is wedged between the lower mold 723a and the upper mold 723b. The connection member 740 has a wedge shape that tapers toward the supply side. The upper surface of the lower mold 723a and the lower surface of the upper mold 723b are inclined surfaces that follow this wedge shape. For this reason, in the third embodiment, the connection member 740 also serves as a displacement mechanism by a mechanical mechanism.

[0085] 15 to 21 are perspective views showing the multi-stage mold 700 shown in Fig. 14, Fig. 15 shows the layer between the first layer mold 711, 721 and the second layer mold 712, 722, Fig. 16 shows the layer between the second layer mold 712, 722 and the third layer mold 713, 723. Fig. 17 shows the second layer mold 712, 722 and the lower mold 723a and the third layer mold 713, the fixed mold 723c and the connecting member 740, Fig. 18 shows the second layer mold 712, the fixed mold 723c and the lower mold 723a and the third layer mold 713, the fourth layer mold 724 and the connecting member 740. Fig. 19 shows the third layer mold 713, the fixed mold 723c, and the connecting member 740, and the fourth layer mold 714, 724, and the upper mold 723b, while Fig. 20 shows the layer between the third layer mold 713, 723 and the fourth layer mold 714, 724. Fig. 21 shows the layer between the fourth layer mold 714, 724 and the fifth layer mold 715, 725.

[0086] As shown in Fig. 14 to Fig. 21, two rows of convex portions 711a, 713a1, 713a2, 715a aligned in the supply direction of the plate material 11 are formed on the upper surface of the first layer mold 711, the lower and upper surfaces of the third layer mold 713, and the lower surface of the fifth layer mold 715. In addition, two rows of concave portions 712b1, 712b2, 714b1, 714b2 aligned in the supply direction of the plate material 11 are formed on the lower and upper surfaces of the second layer mold 712, which are opposite to these, and on the lower and upper surfaces of the fourth layer mold 714. Therefore, the first processing unit 710 performs embossing in which a press stroke is generated in each step every time a pressing operation is generated by the driving unit 300, forming a large number of convex portions 13 on the four plate materials 11.

[0087] The second processing section 720 is provided with a trapezoidal processing section 720a and a flow path port removal section 720b. As shown in Fig. 14, Fig. 16 and Fig. 20, the trapezoidal processing section 720a is provided with a trapezoidal convex portion 723d1 that is convex downward on the lower surface of the lower mold 723a, and is provided with a trapezoidal convex portion 723d2 that is convex upward on the upper surface of the upper mold 723b. The upper surface of the second layer mold 722 and the lower surface of the fourth layer mold 724 are provided with trapezoidal recesses 722e, 724e at positions facing the trapezoidal convex portions 723d1, 723d2.

[0088] 14(a), when the distance between the first processing section 710 and the second processing section 720 becomes shorter, the biting amount at the tip side of the connecting member 740 increases, and the lower die 723a of the third layer die 723 moves slightly downward and the upper die 723b moves slightly upward. As a result, the multi-stage die 700 enters the first state, and the second processing section 720 produces a press stroke at each stage every time a pressing operation is generated by the driving section 300, and performs trapezoidal processing on the second and third plate materials 11b, 11c.

[0089] 14(b), when the distance between the first processing section 710 and the second processing section 720 becomes longer, the biting amount of the tip side of the connecting member 740 becomes smaller, and the lower die 723a of the third layer die 723 moves slightly upward and the upper die 723b moves slightly downward. As a result, the multi-stage die 700 enters the second state, and the second processing section 720 does not perform trapezoidal processing on the second and third plate materials 11b, 11c, although a press stroke is generated in each stage every time a press operation is generated by the driving section 300.

[0090] Further, the flow path outlet portion 720b is provided with a hole for connecting the flow paths 30 between the air conditioning panels 10. The hole is formed adjacent to the partition forming portion 15 by hollowing out, for example, a rectangular shape.

[0091] As shown in Fig. 16 and Fig. 20, the flow path opening portion 720b has hollowing convex portions 723f, 724f for forming holes on the lower surface of the lower mold 723a of the third layer mold 723 and the fourth layer mold 724. Also, on the upper surface of the upper mold 723b of the second layer mold 722 and the third layer mold 723 facing the hollowing convex portions 723f, 724f, member receiving portions 722g, 723g for discarding the hollowed-out member are provided. Here, the hollowing convex portions 723f, 724f and the member receiving portions 722g, 723g are not continuous in the width direction of the plate material 11 but are scattered. Therefore, holes are formed in the second plate material 11b and the third plate material 11c of the four long plates 11 at positions adjacent to the partition forming portion 15. The hollowed out board material 11 is discarded through board material disposal openings 722h, 723h.

[0092] The operation of the plate material processing device according to the third embodiment is substantially the same as that of the second embodiment.

[0093] In this way, according to the plate material processing apparatus of the third embodiment, as in the second embodiment, it is possible to provide a plate material processing apparatus capable of improving the horizontality of the pass line PL in the multi-stage die 700. Also, it is possible to provide a plate material processing apparatus capable of being relatively resistant to vibrations in state transition. Furthermore, it is possible to facilitate synchronous movement and distance adjustment, and also to improve reliability so as to prevent early failures, etc.

[0094] Although the present invention has been described based on the embodiments, the present invention is not limited to the above embodiments, and modifications may be made without departing from the spirit of the present invention. Furthermore, the techniques of the embodiments may be combined, and publicly known or well-known techniques may be combined to the extent possible.

[0095] For example, in the above embodiment, the flow path 30 is a separate flow path for the vapor refrigerant and the liquid refrigerant, but it is not limited to being separate, and may be a common flow path through which both the vapor refrigerant and the liquid refrigerant can flow. In addition, it is preferable that the flow path 30 is provided with a check valve, a temperature sensing valve, etc., as necessary.

[0096] Further, in the above embodiment, the air conditioning panel 10 has a large number of protrusions 13, but this is not particularly limited, and the above manufacturing apparatus may not form a large number of protrusions 13, for example, when the size of the air conditioning panel 10 is small, or the protrusions 13 may not be welded.

[0097] In the above embodiment, the first processing portion 210, 610, 710 forms a large number of protrusions 13, but is not limited to forming a large number of protrusions 13. Similarly, the second processing portion 220, 620, 720 also performs trapezoidal processing, but is not limited to performing trapezoidal processing.

[0098] Furthermore, in the above, the direction of the pressing operation by the driving unit 300 is described as an example from the top to the bottom, but it is not limited to this, and may be the opposite direction. In this case, the fifth layer mold 205, 615, 625, 715, 725 is fixed, and a press stroke occurs in the other stages. The driving unit 300 may also press by sandwiching from above and below. In this case, a press stroke occurs in the other stages except the third layer mold 203, 613, 623, 713, 723. Therefore, the third layer mold 203, 613, 623, 713, 723 can be substantially fixed, and the operability of the shifting mechanism 230, 630, 740 can be easily guaranteed. [Explanation of symbols]
