In general, the recessed rectangular lighting fixture is formed by forming a plate-shaped metal material in the shape of a rectangular container so as to infiltrate a lighting lamp such as a fluorescent lamp inside.

Side of the recessed rectangular lighting fixture should be provided with various types of installation holes for wiring.

However, there have been many structural difficulties in manufacturing a press mold suitable for forming an installation hole on the side of the recessed square luminaire.

In short, a general press die for punching, punching, drawing, etc. has a structure in which the punch fixed to the movable die is vertically lowered and shaped when the metal sheet is supplied to the fixed die.

In the case of forming a hole in the bottom surface of the recessed rectangular lighting fixture, it can be carried out without any difficulty even if using a press of a general type. That is, by forming a supporting means having a height corresponding to the depth of the recessed square luminaire on the stationary die side of the press die, and placing the recessed square luminaire over the support means, the bottom of the recessed square luminaire is Face up.

As such, when the bottom of the recessed square luminaire faces upward, punches that vertically descend with the bottom of the luminaire face each other, thereby making it easier to perforate.

However, in order to perforate the side of the recessed square luminaire, there are problems such as setting of the recessed square luminaire, the direction of perforation, deformation of the recessed square luminaire at the time of punching, and therefore it is difficult to design a press mold suitable for this. Even in the case of design, the structure is complicated and expensive.

In the accompanying drawings, there is shown a recessed rectangular luminaire having an installation hole on its side. The recessed square luminaire 2 shown in FIG. 1 is provided with various installation holes 6 and 7 for wiring in the mounting plate portion 3 and the left and right protection plate portions 4 and 5. .

If using a conventional general press mold structure for drilling the installation hole 7 in the left and right protection plate portions 4 and 5 which are the side surfaces of the recessed square luminaire 2, the recessed square luminaire It would be customary to set (2) so that one of the left and right guard plates (4) and (5) is facing up, and then punch the drill vertically.

However, when attempting to erect the recessed square luminaire 2, the recessed square luminaire 20 has a long length and one side opening, as can be seen in the example shown in FIG. It has a complicated structure in which the flange 8 is formed, it is not easy to install a built-in square lighting fixture stably.

Therefore, the press apparatus is very complicated and expensive, there is a disadvantage that the product is easily deformed when punching.

The present invention is to solve the conventional problems as described above, in the perforated side of the recessed rectangular lighting fixture, to provide a recessed rectangular lighting fixture side perforation device having a very simple structure and can be perforated accurately. There is a purpose.

The tip of the punch punch 100 is slidably inserted into the through hole 112 formed in the scrap bar 110. The front end of the punch punch 100 inserted into the through hole 112 is located inside the scrap bar 110 so that it does not protrude from the scrap bar 110. Accordingly, the scrap bar 110 comes into contact with the left and right protection plates 4 and 5 of the square luminaire 2 before the punching punch 100. Therefore, the punching punch 100 is the punch holder 90 is the compression spring 160 after the scrap bar 110 is in contact with the left and right protection plates (4, 5) of the recessed rectangular lighting fixture (2). After further compressing and further advancing, the perforations of the installation hole 7 are finally made by contacting the left and right protection plates 4 and 5 of the recessed square luminaire.

In other words, after the perforation is completed, the scrap bar 110 can only be released after the perforation punch 100 has retracted and completely removed from the left and right protection plates 4 and 5 of the recessed rectangular lighting fixture 2. The left and right protection plates 4 and 5 of the recessed square luminaire 2 may be separated.

As such, the scrap bar 110 is in close contact with the left and right protection plates (4, 5) of the recessed square lighting fixture (2) prior to the piercing punch (100) to the fixing die (30) so that a stable punching operation is made. do. In addition, even if the punching punch 100 retreats after drilling the installation hole 7, the punching punch () is maintained by pressing the left and right protection plates 4 and 5 of the recessed square lighting fixture 2 one by one. 100 can be easily separated without being caught in the installation hole 7 formed in the left and right protection plates (4, 5) of the recessed square lighting fixture (2), thereby forming a precise installation hole (7) In addition, it is possible to prevent the deformation of the recessed square lighting fixture (2).

FIG. 7 shows a pneumatic or hydraulic circuit for operating the actuating cylinder 50.

As illustrated in FIG. 7, pipes 200 for supplying pneumatic pressure (or hydraulic pressure) for driving the piston 52 are piped to both sides of the operation cylinder 50. In the middle of the conduit 200 is provided with a switching valve 202 to allow the pneumatic (or hydraulic) to act selectively to the outside and the inside of the working cylinder (50). This switching valve 202 is preferably a solenoid valve as shown. The switching valve 202 is controlled by the operation of the switch 204. The switching valve 202 is supplied with pneumatic (or hydraulic) from a predetermined pneumatic (or hydraulic) source 206. The working cylinder 50 is more stable composed of a pneumatic cylinder.

Next, with reference to the accompanying drawings Figures 8a to 8d will be described the operation of the embedded rectangular lighting fixture side perforation device according to the present invention.

First, FIG. 8A shows the initial state in which the recessed rectangular luminaire 2 is set in the perforation device.

As shown in FIG. 8A, when the mounting plate 3 of the recessed square luminaire 2 is turned upward and placed on the fixed die 30, the left and right sides of the recessed square luminaire 2 are side-by-side. The inner surfaces of the protective plates 4 and 5 are in close contact with the side surfaces of the fixed die 30, respectively, and the mounting plate 3 of the recessed square luminaire 2 is in close contact with the upper surface of the fixed die 30. In this way, both inner surfaces of the recessed square luminaire 2 are brought into close contact with the outer surface of the fixed die 30, so that the setting is easy and accurate even if the recessed square luminaire 2 is not set up.

8B shows the state in which the scrap bar 110 is advanced by the working cylinder 50 and in contact with the recessed square luminaire 2.

After the setting of the recessed square luminaire 2 is completed as described above, when the switch 204 is operated, the selector valve 202 is switched so that the pneumatic pressure from the pneumatic source 206 is directed outward of the working cylinder 50. By acting, the piston 52 of the working cylinder 50 advances. As a result, the movable die 70 fixed to the tip of the piston 52 of the working cylinder 50 and the punch holder 90 fixed to the movable die 70 and the scrap bar 110 are advanced together.

At this time, the movable die 70 is slid along the guide bar 132 of the support 130 to be stably advanced.

In this way, the advanced scrap bar 110 supports the left and right protection plates 4 and 5 of the recessed square luminaire 2 set in the fixed die 30. In addition, the support 220 on the upper side of the scrap bar 110 covers the upper surface of the mounting plate portion 3 of the recessed square lighting fixture 2 to prevent the separation or skew of the recessed square lighting fixture 2 during drilling.

Next, FIG. 8C shows a state in which the installation holes 7 are perforated in the left and right protection plates 4 and 5 of the recessed square luminaire 2.

As shown in FIG. 8B, even when the scrap bar 110 contacts the left and right protection plates 4 and 5, which are side surfaces of the recessed rectangular lighting fixture 2, the perforation punch 100 still has left and right protection plates 4. (5) is not reached.

As the piston 52 continues to advance after the scrap bar 110 contacts the left and right guard plates 4 and 5 of the recessed square luminaire 2, the punch holder 90 is compressed by the compression spring 160. Compress and advance. At this time, the punch holder 90 advances along the coupling shaft 150. Since the coupling shaft 150 is fixed to the scrap bar 110 by screwing, the receiving groove 94 of the punch holder 90 is advanced so that the head 156 of the coupling shaft 150 is the receiving groove 94. ) In this way, the perforated punch 100 to advance advances the installation holes 7 in the left and right protection plates 4 and 5 of the recessed rectangular lighting fixture 2. The cut pieces 310 generated according to the perforations fall through the punching holes 32 of the fixed die 30 to the discharge holes 34 and are discharged through the discharge holes 12 formed in the bed 10.

Next, Fig. 8D shows a state in which the perforation punch 100 retreats after the installation hole 7 is drilled.

As described above with reference to FIG. 8C, when the perforation is completed, the selector valve 202 is switched to supply air pressure in the opposite direction at the time of perforation. Accordingly, the piston 52 retreats, and the movable die 70 and the punch holder 90 retreat as the piston 52 retreats. At this time, since the scrap bar 110 maintains the state of elastically pressing the recessed square luminaire 2 by the compression spring 160, the punch holder until the compression spring 160 returns to its original state. Only 90 retreats. Therefore, the perforation punch 100 is first separated from the installation hole 7 of the recessed square lighting fixture 2.

As the perforated punch 100 retreats, the scrap bar 110 continuously adheres the recessed square luminaire 2 toward the fixed die 30 by the elasticity of the compression spring 160. The piercing punch 100 can be separated well without being caught in the installation hole 7.

When the punch holder 90 is continuously retracted and the compression spring 160 is restored to its initial state, the head 156 of the coupling shaft 150 is pulled by the receiving groove 94 of the punch holder 90. As a result, the scrap bar 110 is retracted.

When the scrap bar 110 is completely removed from the ceiling lampshade 2 in this way, the ceiling lampshade 2 is lifted from the fixing die 30 and replaced with a new ceiling lampshade 2.

As described above, the recessed rectangular luminaire side perforation device of the present invention is a recessed rectangular luminaire only by placing the recessed rectangular luminaire 20 on the fixed die 30 in an inverted state in the horizontal direction without setting the recessed rectangular luminaire 20. By the completion of the setting, the setting operation is simple and the setting state is made stable.

In addition, since the perforation is made directly to the side surface of the recessed square luminaire in the horizontal direction, which is the advancing and moving direction of the operation cylinder 50, the movement direction of the operation cylinder 50 should be switched from the vertical direction to the horizontal direction. It is not necessary to add a mechanical structure, the perforating device can be configured in a very simple structure, the perforation can be performed stably and accurately by the fixing die 30, the scrap bar 110, the support 220, and the like. .
