And a magnetic metal detection type proximity sensor 71 disposed on the operation plate 41 for detecting the approach of the detection unit 72.
[0030]
As shown in FIG. 1, in the present embodiment, the pressing process by the press machine 8 includes a trimming press upper die 81 and a lower die 82, and the trimming press lower die 82 is positioned below the trimming press upper die 81. At the position (lower position of the press machine), the plurality of punch pins 83 projecting from the lower surface of the trimming press upper die 81 are lowered to push out burrs in the plurality of processed portions 11 of the rough material 1 shown in FIG. It is configured as follows.
[0031]
The one-cycle operation of the press process including the inspection process in the present embodiment having the above-described configuration will be described with reference to FIG.
[0032]
First, the trimming press lower die 82 which is a press lower die is positioned under the inspection jig when the coarse material 1 for press is charged. At this time, the operator sets the press rough material 1 on the lower trim 82 of the trimming press (step 501 in FIG. 5) and turns on the start switch to start one cycle.
[0033]
The set press coarse material 1 is carried under the trimming press upper die 81 in the press machine 8 by the movement of the lower die 82 and the coarse material table 20 (step 502 in FIG. 5). The die 81 is lowered (step 503 in FIG. 5), and the upper die 81 and the lower die 82 are positioned by the guide pins (step 504 in FIG. 5).
[0034]
As the punch pin 83 is lowered, the burrs in the pressed coarse material 1 are pushed down (step 505 in FIG. 5), the press die 8 is raised by the press machine 8 (step 506 in FIG. 5), and trimming work in the pressing process is performed. finish. Incidentally, at this time, the pressed coarse material 1 remains set on the lower press mold 82.
[0035]
Thereafter, the lower press mold 82 is moved to the inspection position below the inspection mechanism 40 by the moving mechanism 2 (step 507 in FIG. 5), and the rough press material 1 is set. In the specification of the present embodiment shown in FIG. 2, two press rough materials 1 can be set simultaneously.
[0036]
The inspection pin 4 attached to the tip of the cylinder 30 is lowered onto the press rough material 1 (step 508 in FIG. 5). The positioning of the inspection jig and the press rough material is performed by the guide pin bush 6 attached to the operation plate 41 by using again the guide pin 23 of the lower die 82 used for positioning the upper die 81 and the lower die 82 of the trimming press. It is decided.
[0037]
Next, after pressing the coarse material 1 with the coarse material presser 410, deburring is performed in the pressing process described above, and inspection is performed by passing the inspection pin 4 through a hole that should have been deburred and penetrated ( Step 509 in FIG. 5). Then, the inspection pin 4 is lifted by the cylinder 30 and one cycle of the pressing process is completed.
[0038]
The operation and determination at the time of inspection will be described. First, if the burr B in the processed portion 11 of the rough material 1 is not removed due to the punch pin 83 of the trimming press upper die 81 being broken, the inspection pin 4 is formed on the processed portion 11 in the rough material 1. When the jig main body 42 is raised (step 513 in FIG. 5) upon hitting the burr portion B (step 512 in FIG. 5), the detection unit 72 is detected by the proximity switch 71 (step 514 in FIG. 5).
[0039]
However, since the operation plate 41 descends to the lower end, the detection rod 72 attached to the jig main body 42 protrudes, and when it is recognized by the proximity switch as the proximity sensor 71, an NG determination is made, the buzzer is turned on, and the lamp is turned off. Lights up (step 516 in FIG. 5).
[0040]
When the burr B in the processed portion 11 of the rough material 1 is removed, the inspection pin 4 passes through the processed portion 11 of the rough material 1 (step 510 in FIG. 5), and the inspection pin 4 Then, the inspection mechanism 40 is raised (step 515 in FIG. 5).
[0041]
When the burrs B remain in the processed portion 11 of the rough material 1, the inspection pin 4 descends through the processed portion 11 of the rough material 1 and passes through the burrs B (see FIG. In step 511 in FIG. 5, the inspection pin 4 and the inspection mechanism 40 are then raised (step 515 in FIG. 5).
[0042]
In the present embodiment, after pressing the coarse material 1, the press die is moved below the inspection mechanism 40 installed in the press, and the inspection pin 4 attached to the inspection mechanism 40 is moved under the press. The inspection can be automatically performed in the press machine 8 by being lowered to the rough burr removing portion in the mold 81.
[0043]
As an inspection device, the lower die 81 of the press die is moved to below the inspection mechanism 40 provided with the inspection pin 4 as an inspection jig, and inspection is performed. Since no set is required and the lower mold 82 for the inspection jig is not required, an automatic and inexpensive apparatus can be obtained.
[0044]
In the coarse material 1 after pressing, the burrs B that have been temporarily pressed but stuck to the tip of the punch pin 83 and returned to the coarse material 1 when the punch pin 83 is raised may remain. In order to push such burrs B out of the rough material 1, the tip shape of the inspection pin 4 is hemispherical. This is because if the lower end surface of the inspection pin 4 is flat, the burrs B stick to the tip, and the burrs B return to the coarse material again when the inspection pins 4 are raised.
[0045]
If there is an unpressed portion even at one place when the inspection pin 4 is lowered, the operation plate 41 as an inspection plate is provided on the inspection plate guide bar 51 in order to make an NG determination without damaging the inspection pin 4. Coil springs and other springs as spring members are disposed before and after the test plate to float the inspection plate.
[0046]
The NG determination is made when the inspection pin 4 hits the NG portion, raises the inspection jig main body 42, and the detection portion 72 attached to the plate approaches the proximity switch 71. By supporting the lifting force of the tool body 42 with a spring, it was possible to eliminate damage to the inspection pin 4.
[0047]
At this time, since the weight of the inspection jig body 13 is applied to one inspection pin 4 and the inspection pin 4 may be broken, the guide disposed on the jig body 42 that supports the jig body 13. The force applied to the inspection pin 4 could be reduced by arranging the spring members 43 on the upper and lower sides of the rod 51 to bring them into a floating state with respect to the working plate.
[0048]
Since the jig body 42 is supported by the four guide bars 51 for the jig body, the slidability is improved by using the linear bush 44 in order to reduce the operating resistance at the time of NG determination as much as possible. Furthermore, the breakage of the inspection pin 4 could be reduced.
[0049]
In addition, the burrs B that should have been removed in the coarse material 1 after pressing are stuck or stuck to the tip of the punch pin 83 and remain in the processed portion 11 of the coarse material 1 again when the punch pin 83 is raised. Many cases occur.
[0050]
The tip shape of the inspection pin 4 is a hemispherical shape so that such a burr B can be surely pushed out in this inspection process. This is to prevent the burrs that have fallen off when the tip shape is flat from sticking to the tip and returning to the coarse material again.
[0051]
