DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a downlight envelope forming apparatus for molding a downlight envelope.

[0002]

2. Description of the Related Art A downlight enclosure is indispensable for supporting, for example, a downlight type emergency lighting device and the like, and is used by being buried in a ceiling surface. In general, such a downlight envelope is formed by rounding a flat plate having been cut, drilled, and bent into a cylindrical shape and caulking, inserting a top plate into one end of the opening, caulking, and then cutting. It is completed by performing the raising process and the dowel forming process.

[0003] Here, the downlight envelope is housed in a hook for stopping a decorative frame mounting spring for supporting a decorative frame attached to the lower surface opening of the downlight envelope, or in the downlight envelope. A dowel or the like on which a battery mounting bracket for supporting the battery is hooked is provided, and the hooks, the dowels, and the like are formed by cutting and raising processing or dowel forming processing. In this case, since hooks, dowels, and the like are provided at several places, they cannot be formed by only one process. Therefore, conventionally, when forming a hook or a dowel in a downlight envelope, simultaneous molding has been performed by a molding apparatus having multiple heads, or press working has been performed by a single mold for each process.

[0004]

In forming a hook or a dowel in a downlight envelope, simultaneous molding by a molding apparatus having multiple heads is specifically a downlight envelope. This means that a cylindrical work is fixed to a die, and hooks, dowels, and the like are simultaneously processed and formed from a plurality of heads around the die. For this reason, the molding device becomes large and expensive.
In manufacturing the downlight envelope, even if the hooks, dowels, and the like are formed simultaneously at the same time, the effect of shortening the manufacturing time as a whole cannot be expected so much.

[0005] Further, when forming a hook or a dowel in a downlight envelope, when performing press working with a single die for each step, a large number of dies and press machines must be used. Work becomes complicated. In addition, since using many dies and press machines generally means that many workers are required,
There is also a problem that the management of the molding operation is difficult and the cost becomes high.

An object of the present invention is to provide a small and inexpensive apparatus that can perform various processes such as cut-and-raise processing and dowel forming processing on a work serving as a downlight enclosure without trouble. Is to obtain a container molding device.

Accordingly, a cylindrical work serving as a downlight envelope is mounted on a die and chucked by a chuck mechanism, a desired punch is opposed to the work by a punch switching mechanism, and the punch is driven by a punch driving unit. This enables press working with the punch. Then, by rotating the die by a predetermined amount by the rotation driving unit, the punch can face a part already processed and another part of the work, thereby enabling another part of the work to be processed by the punch. Become. Alternatively, the punch for processing the work is switched by sliding the punch in the punch switching mechanism by the slide driving unit,
Another type of processing can be performed on the workpiece. Such various kinds of processing are automatically performed by drive control of the rotation drive unit and the slide drive unit by the control unit.

A dowel on which a battery mounting bracket for supporting a battery stored in the battery is hooked, or a bent or the like for preventing rattling of the battery.

According to a second aspect of the present invention, in the downlight envelope molding apparatus according to the first aspect, the chuck mechanism comprises:
The cylinder is formed by a cylinder provided on the outer peripheral surface of the die so as to be freely retractable, and a retracting mechanism for causing the cylinder to protrude and retract on the outer peripheral surface of the die. Therefore, when the work is mounted on the die and the cylinder is projected from the outer peripheral surface of the die by the retracting mechanism, the tip of the cylinder applies pressure to the inner peripheral surface of the work, and the work is fixed to the die. At this time, since the work is fixed to the die from the inner peripheral surface side, the chuck mechanism does not hinder the work on the side surface of the work, and the degree of freedom of the work by the punch is maintained.

According to a third aspect of the present invention, in the downlight envelope forming apparatus according to the second aspect, the retracting mechanism causes the cylinder to protrude from the outer peripheral surface of the die by air blowing. That is, the cylinder protrudes from the outer peripheral surface of the die by air blow, and the work mounted on the die is securely fixed. It is only necessary to provide a compressor for air blow, and a large-scale structure required for driving a cylinder using oil, for example, is not required.

It has a curvature that matches the curvature of the inner peripheral surface of the work, and is formed smaller than the inner peripheral surface of the work by the same amount as the amount of internal bending of the work. Therefore, the work is smoothly mounted on the die, and even if the work is subjected to inward bending, the work is smoothly extracted from the die. That is, the work of loading and unloading the work with respect to the die becomes easy.

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to the drawings. 1 is a vertical front view of the entire apparatus, FIG. 2 is a vertical side view thereof, FIG. 3 is a vertical front view showing a chuck mechanism by enlarging a die portion, and FIG. 4 is a perspective view of a completed downlight envelope. is there.

First, a die 4 that is driven to rotate by a DC servomotor 3 as a rotation driving unit is provided in a main body case 2 supported by support legs 1 attached to four corners. The die 4 is supported by a plurality of bearings BB and is rotatable about a vertical rotation axis. The die 4 allows coaxial attachment and detachment of a cylindrical work 6 serving as a downlight envelope 5. The outer peripheral surface 4a of the die 4 is
The outer peripheral surface 4a of the die 4 is formed to have a slightly smaller diameter than the inner peripheral surface 6a of the work 6. Specifically, the outer peripheral surface 4 a of the die 4 is smaller in diameter than the inner peripheral surface 6 a of the work 6 by the amount of the inner bending of the work 6.

Next, the die 4 is provided with a chuck mechanism 7 for fixing the work 6. The chuck mechanism 7 is formed by a cylinder 8 provided on the outer peripheral surface 4 a of the die 4 so as to be able to protrude and retract, and a retracting mechanism 9 for causing the cylinder 8 to protrude and retract on the outer peripheral surface 4 a of the die 4. The cylinder 8 is urged in the anti-radiation direction, that is, in the direction of the center of the die 4 by a coil spring 10 which constitutes a part of the retracting mechanism 9. The cylinder 8 can be urged in a radial direction, that is, in a direction protruding from the outer peripheral surface 4a of the die 4, by an air blow mechanism 11 constituting another part of the retracting mechanism 9. That is, the air blow mechanism 11 transmits air output from an air compressor (not shown) to the air pipe 1.
This is a structure for guiding to the rear surface of the cylinder 8 through the second member 2.

Next, a plurality of punches 13 are positioned on the main body case 2 at positions facing the side surfaces of the work 6 fixed to the die 4, and these punches 13 are slid in a direction perpendicular to the axial direction of the die 4. A punch switching mechanism 14 is provided for freely supporting. This punch switching mechanism 14
A slider 15 for selectively holding a plurality of punches 13 is formed by being slidably attached to a slider rail 16. And a plurality of punches 1
The slider 15 holding 3 is driven and slid by a slide drive unit 17 having a cylinder structure.

The slider rail 16 itself can be freely moved toward and away from the die 4. That is, the slider rail 16 is attached to a retractable output shaft 19 provided on an air cylinder 18 as a punch driving unit.
The output shaft 19 moves forward and backward by the operation of the air cylinder 18, and comes into contact with and separates from the die 4. Therefore, the air cylinder 18 also serves as a punch operation mechanism that supports the punch 13 slidably in the direction of the die 4.

Here, the die 4 is formed with a plurality of insertion holes 21 into which positioning pins 20 protruding from the slider 15 are inserted. The insertion hole 21 and the positioning pin 20 are arranged so that the punch 13 correctly faces the work 6 in a state where the positioning pin 20 is inserted into the insertion hole 21. Therefore, work 6
An insertion hole 21 is formed at each point where a press process is performed on each of the holes, so that each processing position is correctly positioned.

Further, the main body case 2 is provided with a control unit (not shown) for driving and controlling the DC servo motor 3 as a rotary drive unit, the slider drive unit 17 having a cylinder structure, and the air cylinder 18 as a punch drive unit. I have. This control unit has a microcomputer configuration and has a DC
Servo motor 3, slider drive unit 17 and air cylinder 1
8 are driven by a predetermined amount managed respectively.

In such a configuration, in order to manufacture the downlight envelope 5, a flat plate is cut, drilled, and bent, and then the flat plate is rolled into a cylindrical shape and swaged, and the flat plate is cut into one end. Insert the top plate. Then, such a cylindrical shape is mounted on the die 4 as a work 6, and cut-and-raised processing and dowel forming processing are performed. As a result, a pair of hooks 22, dowels 23, and bends 24 are formed on the work 6, respectively, and the downlight envelope 5 is completed. Here, the hook 22 is for stopping a decorative frame attaching spring (not shown) for supporting a decorative frame (not shown) attached to the lower surface opening of the downlight envelope 5. Is for hooking a battery mounting bracket (not shown) for supporting a battery (not shown) housed in the downlight envelope 5, and the bend 24 causes the rattling of the battery. This is to prevent it.

The apparatus for manufacturing a downlight envelope according to the present embodiment performs a cutting and raising process and a dowel forming process on a cylindrical work 6. The details of these processes will be described below.

First, after the work 6 is mounted on the die 4, the air compressor is driven by the drive control operation of the control unit, and the air is sent to the chuck 10 via the air pipe 12. Then, the chuck 10 projects from the outer peripheral surface 4a of the die 4 against the urging force of the coil spring 10, and the work 6
Is pressed on the inner peripheral surface 6a. Thereby, the work 6 is fixed to the die 4. In this state, since the work 6 is fixed to the die 4 from the inner peripheral surface 6a side, the chuck mechanism 7 does not hinder the processing of the side surface of the work 6 and the punch 1
3, the degree of freedom of the processing operation is maintained. Further, since the chuck 10 is driven by an air compressor for air blow, the structure for that is simple and the parts cost is low.

Next, the desired punch 13 is made to face the work 6 by the punch switching mechanism 14. When the air cylinder 18 is operated in this state, the slider rail 16 attached to the output shaft 19 moves in the direction of the die 4, and the work 6 can be pressed by the punch 13. At this time, the die 4 is driven by the DC servomotor 3.
Is rotated by a predetermined amount, so that the punch 13 can face a portion different from the already processed portion of the work 6,
Thus, another portion of the work 6 can be processed by the punch 13. Alternatively, by sliding the punch 13 in the punch switching mechanism 14 by the slide drive unit 17, the punch 13 for processing the work 6 can be switched, and another type of processing can be performed on the work 6. Such various kinds of processing are automatically performed by controlling the drive of the DC servomotor 3, the slide drive unit 17, and the air cylinder 18 by the control unit.

Here, in the case of the present embodiment, first, the punch 13 for forming the dowel 23 is made to face the work 6 to form the first dowel 23, and then the DC servo motor 3
The die 4 is rotated by 180 degrees to rotate the second dowel 2
Form 3 Subsequently, the slider 15 is slid by the driving of the slider driving unit 17 so that the hook 22 and the bending 2
The punch 13 for forming the workpiece 4 faces the workpiece 6,
A first hook 22 and a bend 24 are formed. After this,
The die 4 is rotated 180 degrees by the DC servo motor 3 to form the second hook 22 and the bent portion 24. Thus, the downlight envelope 5 is completed.

After the machining, the drive of the air compressor is stopped by the drive control operation of the control unit. As a result, the cylinder 8 is no longer biased by air.
The cylinder 8 returns to the original position by the urging force of the coil spring 10. Thereby, the work 6 can be removed from the die 4. At this time, the outer peripheral surface 4a of the die 4
Has a curvature that matches the curvature of the inner peripheral surface 6a of the work 6, and is formed to have a slightly smaller diameter than the inner peripheral surface 6a of the work 6, so that the work of extracting the work 6 from the die 4 is easy. . The small amount of the outer peripheral surface 4a of the die 4 having a smaller diameter than the inner peripheral surface 6a of the work 6 means that the work 6
Is equivalent to the amount of inward bending at the bent portion 24 of FIG.

Therefore, according to the downlight envelope forming apparatus of the present embodiment, it is possible to efficiently perform desired processing on the work 6 with one apparatus. And the downlight envelope molding device itself is also small and inexpensive.
