DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a center window processing apparatus for bending an edge of a center window into an L-shape on a door panel, and more particularly to a technique for bending the entire edge of the center window.

[0002]

2. Description of the Related Art Generally, when a middle window such as a lighting window is formed in a door panel, a rectangular opening is punched in a desired portion of the door panel, and an edge of the opening is formed into, for example, an L-shape or a corrugated opening. Fold it into a letter shape, and attach a shoji, gull, louver, etc. to this part. As such a method of processing a middle window of a door panel, for example, a method described in Japanese Patent Publication No. 5-3869 is known.

FIG. 12 is an explanatory view showing the structure of a work material when a center window is machined by using the above-mentioned conventional apparatus. As shown in FIG. The portion 102 is punched, and small rectangular openings 103 are also punched at the four corners of the rectangular opening 102. Then, the folding margin 104 along the four sides of the opening 102 is bent into an L-shape. Further, the work material 101 is bent in an L-shape along a folding margin 105 around the periphery. As a result, the work material 10 in which the middle window is formed as shown in FIG.
1 can be created.

However, in such a conventional method for processing a middle window, it is necessary to punch small openings 103 at four corners of the opening 102 in order to bend the folding margin 104 as described above. Therefore, when attaching a shoji, a rag or the like, a gap is formed at the four corners, and it is necessary to fill the gap with a packing or the like in order to cover this part. In addition, the width of the center window is limited by the dimensions of the sawing tool, and in the above-mentioned conventional apparatus, the minimum width is about 130 mm, and the center window cannot be machined to a width smaller than this. For this reason, for example, there is a disadvantage that a slit-shaped opening for forming a window for lighting cannot be punched.

[0005]

As described above, the conventional apparatus for processing the middle window of a door panel has a drawback that packings and the like must be attached to the four corners of the processed middle window. There was a problem that a narrow middle window could not be machined.

The present invention has been made to solve such a conventional problem, and an object of the present invention is to provide an L along the entire periphery of an opening punched for a middle window.
It is an object of the present invention to provide a middle window processing apparatus for a door panel which can be bent in a character shape and can be bent with a narrow width.

[0007]

In order to achieve the above object, according to the first aspect of the present invention, the length of the squeeze-bending mold is changed according to the size of the middle window of the door panel, and the edge of the opening of the middle window is changed. In the middle window processing device of the door panel to be bent into an L-shape, the upper die block, a ram for lowering the upper die block at a predetermined press pressure, and a lower die disposed below the surface from which the work is sent out, An upper die that is arranged above a surface from which the work is sent out and is fixed to the upper die block;
The lower mold is divided into a plurality of parts in a direction (lateral direction) perpendicular to the workpiece feeding direction, and the middle part lower mold disposed in the middle part has a substantially rectangular parallelepiped shape and is detachable. Further, the lower die at both ends disposed at both ends has a tilting member having a cross-section “H” shape which can be tilted appropriately in a seesaw type, and the upper die has a front edge substantially equal to the rear edge of the lower die. A rear-stage upper die that is arranged in parallel, a front-stage upper die in which a rear edge is arranged to substantially coincide with a front edge of the lower die, and an end-end upper die that is disposed on both sides of the lower die. And, the upper part of the front part and the upper part of the rear part are fixed rotatably with respect to the upper part block, and are further disposed on the front part and the rear part of the lower part, and are formed at the time of press working. A cushion material which elastically contacts the upper part of the rear part and the upper part of the front part; The lower mold is a lower mold fixing cylinder for fixing pressed laterally, it is characterized by having a tilting means for tilting in either direction before and after the tilting member.

According to a second aspect of the present invention, a split spacer is disposed below the plurality of mold members constituting the lower mold and determines which one of the mold members works effectively. It is characterized by. In the invention according to claim 3, at least one of the plurality of lower molds divided in the lateral direction is an insertion mold having a groove for lifting, and the fixing by the cylinder for fixing the lower mold is loosened. After that, an insertion-type attaching / detaching mechanism for attaching / detaching the insertion mold to / from a plurality of lower molds is provided.

According to a fourth aspect of the present invention, the tilting means for tilting the lower die at both ends has a wide portion and a narrow portion.
The tilting members are tilted in a see-saw manner by moving the operation plates in opposite directions, in parallel to each other, abutting against the eye plate and fixing the same, and moving the tilting cylinder attached to the opposite surface of the eye plate forward and backward. It is characterized by making it.

According to the present invention constructed as described above, the work is sent out so that the long side of the opening of the middle window faces in the horizontal direction, and the middle window is moved between the rear edge of the lower die and the upper die of the rear stage. The rear long side and the rear two corners of the opening are L-shaped and bent. At this time, the upper stage upper die is lifted upward to be in a standby state, and the tilting member is set to tilt from the front side toward the rear side. Next, the upper die in the former stage, which has been in the standby state, is lowered to be ready for use, and the upper die in the latter stage is lifted upward to be in the standby state. In this state, the work is moved a predetermined distance, and the lower die The front long side and the two front corners of the middle window opening are bent into an L-shape between the front edge of the front mold and the upper die of the front section. At this time,
The tilting member is set so as to tilt from the rear side toward the front side. As a result, the middle window opening 2
One long side and four corners are bent into an L shape.

Next, the number of effective lower dies is adjusted by moving the division spacer, and the length is set so as to match the short side length of the middle window opening. And work 90
Rotate so that the short side of the middle window opening is oriented in the horizontal direction, and between the rear edge of the lower mold and the upper mold at the rear, and the front edge of the lower mold and the upper mold at the front. And two short sides are L-shaped. As a result, the entire periphery of the middle window opening is bent into an L-shape, and the corners are smoothly bent by the seesaw-type tilting member attached to the lower mold at both ends. So the accuracy of the finish is good. In addition, since the lower mold is configured to be divided into a plurality of parts in the horizontal direction, even if the width of the middle window of the work to be processed is changed, it can cope with this.
In addition, since a middle window having an opening width larger than the vertical width of the lower die can be processed, a narrow middle window such as a slit can also be processed.

Further, one of the plurality of divided lower dies is an insertion type, and the insertion type is automatically attached and detached by using an insertion type attaching / detaching mechanism, so that the rear surface and the front surface of the door panel can be removed. As described above, panels having different opening widths can be alternately and efficiently formed.

[0013]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a configuration diagram showing an embodiment of a middle window processing device of a door panel to which the present invention is applied. As shown in FIG. 1, the middle window processing device is disposed above a delivery surface of a work 1. The upper mechanism 2 is roughly divided into an upper mechanism 2 and a lower mechanism 3 disposed below.
The upper mechanism 2 is lowered at a predetermined press pressure by operating the ram 4 disposed at a predetermined pressure to apply a constant pressure to the work 1 to perform the bending work.

The upper mechanism 2 includes an upper block 5, a front upper die 6, a rear upper die 7, which is fixed to the upper die block 5.
It is composed of two upper end dies 8a and 8b.
At the upper part, a ram 4 for applying a pressing pressure to the upper mold block 5 is provided. The upper die 6 at the front part and the upper die 7 at the rear part are rotatable about the rotation shafts 9 and 10, respectively, as described later. Can be lowered to a usable state, or can be turned laterally to a standby state.

The lower mechanism 3 includes a lower mold 11 divided into a plurality of pieces in a lateral direction (a direction orthogonal to the workpiece 1 feed direction), and a rear-stage cushioning material 12 disposed on the rear side of the lower mold 11.
And a front cushion member 13 disposed on the front side of the lower mold 11. A spring member 14 for providing elasticity is disposed below each of the cushion members 12, 13. ing. Further, a wedge 15a, 1 for switching whether or not the cushion members 12, 13 function effectively is provided below each spring member 14.
5b are arranged. That is, the wedges 15a, 15
When b is turned on, the cushion members 12 and 13 can support the pressure from above with a certain elasticity. However, when the wedges 15a and 15b are turned off, the cushion members 12 and 13 have a low elasticity and descend with a small force.

FIG. 2 is an explanatory view showing the structure of the lower mold 11 as viewed from the "AA" direction shown in FIG. 1. As shown, the lower mold 11 has a plurality of narrow molds. Middle lower mold 11a
And the only insertion mold 11b slightly wider than the middle lower mold 11a, and the lower end molds 11c, 11 arranged at both ends.
d. The lower end mold 11c on the left side in the figure is connected to the shaft CY1a of the cylinder CY1 (cylinder for fixing the lower mold), and the lower mold 11c can move in the left-right direction by the stroke operation of the cylinder CY1. I have. When a stroke operation is performed on the right side in the figure (in the direction of arrow B), the entire lower mold can be firmly fixed. When a stroke operation is performed on the right side in the figure (in the direction of arrow C), The entire lower mold 11 is loosened, and the intermediate lower mold 11a and the insert mold 11b can be detached.

The lower intermediate mold 11a is a clamp (not shown).
The number of the intermediate lower molds 11a is determined as appropriate according to the width of the middle window to be processed. Therefore, the width of the middle window can be set in units of the width (for example, 100 mm) of the middle lower die 11b. Insertion type 11
b can be automatically operated by the insertion-type attachment / detachment mechanism 16 (the details will be described later).

Further, a plurality of divided spacers 51 are arranged below each of the divided lower dies 11a and 11b.
As shown in detail in FIG.
Are connected to a plurality of chain pieces 53 constituting the chain 52, respectively. By rotating the chain 52 and moving the split spacer 51, the number of effective lower dies among the plurality of lower dies 11 can be determined. That is, the chain 52 is meshed with the sprocket 54, and the rotating spacer 55 connected to the center of the sprocket 54 is driven to rotate by a motor (not shown) so that the split spacer 51 is sent out to the lower side of the lower mold 10. When the division spacer 51 is arranged on the lower side, the lower mold 11 is lifted upward, and the bending operation can be performed using the lower mold 11.

Further, among the divided spacers 51, the one 51-n located at the foremost end has its edge portion chamfered into a smooth arc shape, and the lower die having the edge portion divided is formed. 11 and can be lifted upward in contact with the side surface. More specifically, when the chain 52 is moved in the direction of arrow “F” in the figure with the edge of the split spacer 51-n in contact with the side surface of the lower mold 11, the lower mold 11 is lifted upward. Then, the divided spacer 51 is inserted into the lower side of the lower mold 11. Thus, the effective number of lower dies 11 can be set by rotating the chain 52.

The lower end dies 11c and 11d (see FIG. 2)
As shown in FIG. 3, a tilting member 21 capable of tilting in a seesaw manner is attached to a corner portion.
Is tilted in either direction by the forward / backward movement of the tilting mechanism 22.

FIG. 4 is an explanatory view showing the structure of the tilting mechanism 22. As shown in FIG. 4, the tilting mechanism 22 is provided with two operating plates 2 in a direction orthogonal to the strip-shaped eye plate 23.
4a and 24b are attached, and one of the operation plates 24a has a wide end portion and the other operation plate 24b has a wide root portion. A shaft end of a cylinder CY2 (tilting cylinder) is fixed to the other surface of the eye plate 23. Therefore, the two operation plates 24a and 24b move forward and backward by the stroke operation of the cylinder CY2. It has become. Then, as shown in FIG. 2, each operating plate 24a, 2
Since the tilting member 21 is arranged supported by 4b, the tilting member 21 is tilted in one of the right and left directions by this reciprocating operation. For example, cylinder CY
2 slides in the contracting direction, the tilting member 21 is placed on the portions a1 and b1 of the operating plates 24a and 24b shown in FIG. In this case, as shown in FIG. 5A, the tilting member 21 tilts so that the left side is lifted. On the contrary, when the cylinder CY2 slides in the extending direction, the a2, b2 of the operation plates 24a, 24b
Since the tilting member 21 is placed on the portion, the tilting member 21 tilts so that the right side is lifted as shown in FIG. 5B. As a result, as described later, it is possible to perform the bending work on both the front edge and the rear edge of the lower mold 11.

FIG. 6 is an explanatory view showing the structure of the insertion type attaching / detaching mechanism 16. As described above, by using this attaching / detaching mechanism 16, the insertion mold 11b shown in FIG. 2 can be automatically attached / detached. You can do it. Here, the insertion mold 11b
The purpose of changing the processing width by attaching / detaching is explained. FIG. 7 is a cross-sectional view of the middle window portion of the completed door panel. As shown in the figure, the back plate 31 and the front plate 32 are abutted, and the middle window is formed by using a fastener 33, a packing 34 and the like. The glass 35 is fixed. As can be understood from the drawing, the opening widths of the back plate 31 and the front plate 32 are different. That is, the width L1 is formed larger than the width L2.

In general, when processing a door panel, a method of processing the back plate 31 first and then processing the front plate 32 is not adopted. The back plate 31 and the corresponding front plate 32 are processed alternately and sent out to the next step. Therefore, the middle windows having different opening widths are alternately machined. Each time the middle lower mold 11a is manually attached and detached, the workability is significantly reduced. This is solved by automatically attaching and detaching the.

FIG. 6A is a plan view of the attaching / detaching mechanism 16, and FIG. 6B is a side view. This attachment / detachment mechanism 1
6 has a rotating shaft 41 and an arm 42 that can rotate about 90 ° about the rotating shaft 41 in the direction of arrow “E”. Further, the rotating shaft 41 and the arm 42 have a stroke of the cylinder CY3. It can be moved up and down by operation. A pinion (not shown) attached to the rotating shaft 41 is engaged with a rack 43, and the rack 43 is connected to the cylinder CY4.
2 rotates.

Further, a horizontal rod 44 is disposed inside the arm 42, and a vertical rod 45 is disposed inside the rotary shaft 41. These horizontal rods 44 and vertical rods 45 are in surface contact with a tapered surface T. . A cylinder CY5 is provided at the lowermost end of the vertical rod 45, and the vertical rod 45 can be slid in the vertical direction by the stroke operation of the cylinder CY5. Accordingly, the horizontal rod 44 that is in surface contact with the vertical rod 45 on the tapered surface T slides in the horizontal direction in conjunction with the vertical movement of the vertical rod 45. The other end of the horizontal rod 44 is in contact with a hook 46, which is urged by a spring 47. The tip of the hook 46 is formed in the groove 4 formed inside the insertion mold 11b.
7. Thus, when the cylinder CY5 performs a stroke operation, the engagement and release between the hook 46 and the insertion mold 11b can be switched. That is, by operating each of the cylinders CY3, CY4, and CY5, the insertion mold 11b can be attached or detached.

Next, the operation of the present embodiment configured as described above will be described. Generally, the middle window formed on the door panel has a rectangular shape, and in the middle window processing apparatus of the present embodiment, the bending process is started from two long sides of the middle window. First, when the length of the long side is determined, the width of the lower mold 11 shown in FIG. 2 is determined according to this length. As described above, since the length can be set in units of the width of the middle lower mold 11a, the length can be set, for example, every 100 mm. When the setting of the width of the lower die is completed, the interval between the upper end dies 8a and 8b shown in FIG. 1 is set so as to match the width. At this time,
Of the plurality of divided lower dies, the insertion die 11b is not used and is kept in a standby state, and the divided spacers 51 disposed below the lower die 11 are so arranged that all the lower dies 11 effectively work. Set. Further, the tilting mechanism 22 is operated by operating the left and right cylinders CY2 to set the tilting member 21 so as to tilt from the rear side to the front side (that is, the state shown by the reference numeral 21 in FIG. 1).

Next, as shown in FIG. 9, the rotary shaft 9 is rotated by about 90 ° to lift the front stage upper die 6 upward to be in a standby state, and further, is located at a position facing the front stage upper die 6. In order to stop the function of the cushion material 13, the wedge 15a is turned off. Then, in this state, when the rear long side of the middle window opening formed in the work is made to coincide with the rear edge of the lower die 15 and the ram 4 is operated to lower the upper die block 5, the upper die 5 Since the mold 7 presses down the cushion material 12 and descends, the bending process is performed between the upper mold 7 and the lower mold 11 at the rear part, and the rear long side of the middle window is bent into an L-shape.

At this time, since the tilting members 21 arranged at both ends of the lower mold 11 are set so as to be inclined from the rear stage to the front stage, the corner portion of the middle window is formed as shown in FIG.
It is processed so as to be smoothly bent as shown in FIG.

Next, the upper die block 5 is lifted to release the work 1, and this time, as shown in FIG.
To raise the rear upper die 7 upward by about 90 ° to be in a standby state, and to turn off the wedge 15b.
On the other hand, the upper die 6 in the front part is lowered downward to make it usable, and the wedge 15a is turned on. Furthermore,
By operating the tilting mechanism 22, the tilting member 21 is now operated so as to tilt from the front side to the rear side (state of the reference numeral 21 shown in FIG. 11). Then, in this state, the work 1 is sent to the downstream side, the front long side of the middle window opening and the front edge of the lower mold 11 are made to coincide, and the ram 4 is operated to lower the upper mold block 5. As a result, the front upper die 6 descends and presses the cushioning material 13, so that the front die upper die 6 and the lower die 11 are bent and the front long side of the middle window opening is formed. It will be bent into an L-shape. At this time, since the tilting member 21 is set so as to be inclined from the front part to the rear part, the corner part is machined so as to rise up smoothly as in the previous bending. By this step, as shown in FIG. 10B, two long sides and four corners are bent into an L-shape.

In the next step, the short side of the middle window opening is bent into an L-shape. As shown in FIG. 10 (b), since the four corners have already been bent, the short side is only the side (excluding the corner).
And bend it. Therefore, the chain 52 shown in FIG. 2 is rotationally driven to move the divided spacers 51, and the number of effective lower dies 11 is determined. In other words, the lower mold 1 used so as to have the same length as the short side of the middle window opening.
Set the number of 1. Then, in this state, the short side of one of the short sides is cut and bent by the upper die 7 and the lower die 11 in the same manner as described above.
The other short side is cut and bent with the lower mold 11. As a result, the entire periphery of the middle window opening of the door panel is bent into an L-shape.

As described above with reference to FIG. 7, when continuously processing workpieces having different opening widths, such as the back panel 31 and the front panel 32 of the door panel, the cylinder CY1 shown in FIG. Release to release the fixation of the lower mold 11, then
Using the insertion type attaching / detaching mechanism 16, the insertion type 11b is
Insert into 1. That is, when the cylinder CY4 moves forward and backward with the hook 46 hooked on the groove 48 of the insertion mold 11b, the rotation shaft 41 is rotated by the rack 43, and the insertion mold 11b moves above the insertion position of the lower mold 11. Is done. When the cylinder CY3 is moved forward and backward in this state, the insertion mold 11b is inserted into a predetermined position of the lower mold 11, and by moving the cylinder CY5 forward and backward, the vertical rod 45 and the horizontal rod 44 are moved. Slides, the hook 46 rotates against the urging force of the spring 47, and the hook 46 is released from the groove 48 of the insertion mold 11b. This completes the insertion of the insertion mold 11b, so that the cylinder CY1 shown in FIG. Correspondingly, the upper end die 8 shown in FIG.
The widths of a and 8b are changed, and in this state, the same bending work as described above can be performed to form a middle window having a different opening width from the previous time.

As described above, in the middle window processing apparatus of the door panel according to the present embodiment, first, the work 1 is sent out with the long side of the middle window opening portion directed in the width direction, and the rear edge of the lower mold 11 is used. After bending the rear long side, the front long side of the lower die 11 is bent using the front edge. Further, the work 1 is rotated by 90 °, and the two short sides of the middle window opening are similarly bent. Therefore, the work for rotating the work 1 only needs to be performed once, and the work 1 is simply rotated by 90 °, so that the workability is remarkably improved. Further, by using the tilting member 21, the corner portion can be processed on the inclined surface, so that the finish of the corner portion is good and the processing accuracy is improved.

Further, at the time of short side processing, the width of the lower die can be easily changed by moving the chain 52 and switching the number of divided spacers 51 to be used, so that the labor required by humans can be reduced. When two workpieces 1 having different opening widths are continuously processed like the back panel 31 and the front panel 32 of the door panel, the insertion die 11b is immediately moved to the lower die 11 by the insertion die attaching / detaching mechanism 16. Therefore, the workability is good, and the efficiency of the work in the post-process can be improved.

The length of the short side can be arbitrarily set as long as it is longer than the vertical length of the lower mold 11 (the distance L3 shown in FIG. 1). The window opening can also be easily processed. Furthermore,
Since the entire periphery of the middle window opening is bent into an L shape,
There is no need to perform operations such as putting packings at the four corners as in the related art, and the workability is improved.

[0035]

As described above, according to the present invention,
The lower mold divided in the horizontal direction, the upper part of the rear part, the upper part of the front part,
Since the middle window opening formed in the work is bent in an L-shape by the upper die having the upper end die and the upper die, it is possible to set an arbitrary width and perform the bending work. In addition, when the entire periphery of the opening of the middle window is to be bent, it is not necessary to rotate and insert the work many times, and it is only necessary to perform the 90 ° rotation once, so that the workability is improved. Furthermore,
Since the lower molds at both ends have a tilting member that can tilt in a seesaw manner, the tilting member is appropriately tilted and bent to improve the finish of the corner portion. Further, since the entire periphery of the middle window opening is bent into an L-shape, it is possible to save time and effort for loading packings at four corners as in the related art.

In addition, since the number of the lower molds that are effectively divided among the plurality of divided dies can be determined by using the divided spacers, it is easy to process the short side of the opening of the middle window. Can be set to this length. Furthermore, when two types of workpieces having different opening widths are alternately bent and bent, the insertion die can be automatically attached and detached using the insertion type attachment / detachment mechanism, and the width of the sawing and bending can be changed. Workability is improved. Further, even if the opening width of the slit is narrow, it can be processed as long as it is larger than the width of the lower die in the vertical direction.
