Abstract

PURPOSE:To securely detect a material to be worked without reference to the shape of the working surface of a die even when the material to be worked is not a magnetic body, by allowing a proximity switch to detect an oscillatory lever rotating by being pressed against an end part of the material to be worked. CONSTITUTION:When a material to be worked presses the lower end part 16b of an oscillatory lever 16, the oscillatory lever 16 rotates counterclockwise around a pin 17 as an axis and the lower end part 16b is pressed to right. Consequently, the pin 17 moves to right in a long-sized hole 14a of a supporting plate 14 to shorten the distance between the pin 17 and a pin 19a, thereby moving up the coupling pin 19 for the oscillatory lever 16 and a link 18. When the lower end part 16b abuts on an end part of a base plate 13, the detection head 4a of a proximity switch 4 and the proximity projection 16c of the oscillator lever 16 are placed at a set-length interval, and the proximity switch 4 detects the material to be worked being installed at a normal position and then sends a signal.

The lower end is made to protrude toward the inside of the mold in the ft111 direction by the action of the bulge provided at the upper end, and the swinging lever of the RHMob lever moves the lower end into the 2Fl! When the edge of the workpiece to be accommodated reaches the position set by the pressing tongue on the same side, the swinging lever comprises a proximity switch for detecting the approach of the lower end; A material quality II and confirmation device characterized in that it is configured to be movable in a direction perpendicular to a detection surface of a detection head of a proximity switch within a range that absorbs dimensional errors of a workpiece at a shaft attachment part. 6. DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a device for detecting whether a material to be processed (1) is accommodated in a proper position in a press mold or the like. Conventionally, when a workpiece such as a sheet metal is housed in a press mold, especially a lower mold, in order to know whether the workpiece has been placed in the correct position of the mold, for example,
As shown in Fig. 1, when the workpiece is stored in the lower mold & of the press at the proper position, the approach of the workpiece W is directly prevented. A proximity switch (b) was installed at a location where it could be detected. For this reason, there are restrictions on where proximity switch b can be installed, and the surface of the press die that accommodates the workpiece is curved, making it difficult for the workpiece to be in the correct position when it is set in the press die. Furthermore, there is a drawback that detection cannot be performed even if the workpiece is not magnetic. In view of the above, the present invention has been developed so that no matter what shape the machined surface of the mold has or even when the workpiece is not a magnetic material, when the workpiece is set in the regular position of the mold, the workpiece The purpose is to provide a device for checking the setting position of a material in a press die, etc., which can reliably detect the workpiece. Next, the present invention will be explained based on embodiments shown in the drawings. In FIGS. 2 to 4, a pair of side plates 12, 12 of the position confirmation device 11 are fixed to the vertical section of the substrate 13 in parallel with the upper surface thereof. A proximity switch 4 is installed between the side plates 12, 12 to detect when a magnetic material such as metal approaches within a certain distance. In addition, this side plate 12,1
A pair of support plates 14 having elongated holes 14a are disposed on the upper left side of 2.
.. 14 (however, one support plate 14 is not shown) is provided protrudingly, and a placket 15 is fixed to the upper right end of the side plate 12.12. The swing lever 16 is made of a bent metal member having an obtuse angle, and the bent portion is rotatably supported by a pin 17 inserted into the long sides 14a, 14a of the support plate 14.14. ing. This ft1m
The lever 16 has its lower end connected to one end of an H-shaped link 18 by a V-shaped pin 19, and the other end of the link 18 is connected to a pin 19a). The swinging lever 16 has its bent portion connected to the side plate 12 as described above.
The upper end 16a is attached to the pin 17 because the link 18 and the like are attached to its upper end 16a. is always high, and the lower end portion 16b is always light. Therefore, the link 18 is substantially horizontal, and the lower end 16b of the swing lever 16 is always separated from the head 4a of the proximity switch 4. When a pressing force in the direction of the arrow (downward) is applied to the lower end 16b (see FIG. 6), the swing lever 16 rotates counterclockwise about the pin 17, and the lower end 16b is pushed to the right in the diagram. Therefore, pin 17
moves to the right in the elongated hole 14a of the support plate 14 and removes the pin 1.
7 and the pin i9a is short, the connecting pin 19 portion of the swing lever 16 and the link 18 moves upward. When the lower end 16b comes into contact with the end of the substrate 13 (on the detection head 4a side), the swing lever 16 and the link 18 also stop moving. Next, the implementation of this example will be explained. In FIG. 5, a lower die of a 20-piece press is used, and an appropriate number of guides 21 are attached to one flange 20a of the upper part of the lower die 20, and a suitable number of guides 21 are attached to the two sides of the other flange 20b. position [dt confirmation device 11 moves its swinging lever 16 inward (fi
ll (guide 21 flll+), and attach an appropriate number of them according to the size of the mold. Then, when the workpiece Sheet) w is housed in the lower die 4920 from above the lower mold 20 with one end thereof being guided by the guide 21, the other end of the Sheet) w is attached to the swing lever 16. Lower end 16b
Press down. In this way, the lower end 16b is
6 & is pushed down, so the swing lever 16 rotates counterclockwise around the pin 17. Then, when the sheet w is placed in the proper position 1d of the lower die 20,
The lower end 16b of the swing lever 16 comes into contact with the tip of the I& plate 16. Therefore, the detection head 4a of the proximity switch 4
, and the distance between the commuting lever 16 and the proximity riser 16Q is the set length D, and the proximity switch 4 is
It detects that it is stored in the correct position of 0 and issues a signal. In this way, when a signal is issued from all the position confirmation devices 11 attached to the lower die 20, the ram of the press (not shown) to which the upper die is attached can be operated based on this signal. Here, in the position confirmation device 11, the hole that supports the pin 17 of the support plate 14 is an elongated hole, and the pin 17 is inserted into the elongated hole 14a.
Even if there is some error in the length of the sheet w, the error in the length of the sheet w can be absorbed within the length of the elongated hole 14a, and the sheet w can be moved within the lower mold. 20 can be detected whether or not it has been correctly accommodated. Furthermore, a spring or the like may be used in place of the link 18 of the position confirmation device 11. As described above, the present invention comprises a substrate attached to the upper surface of a press die, a chevron-shaped metal member having an upper end, a central bent portion, and a lower end, and the bent portion is axially positioned above the substrate. a swinging lever whose lower end protrudes toward the inside of the mold due to the action of a weight 9 provided at the upper end; It consists of a proximity switch that detects the approach of the lower end when it is pressed by the end of the lever and rotated to a set position, and the swing lever absorbs dimensional errors of the workpiece at its shaft attachment part. Since the material position confirmation device is formed so as to be movable within a range perpendicular to the detection surface of the detection head of the proximity switch, the following effects can be obtained when this device is attached to a press mold or the like. (1) Since it is detected at the end of the workpiece whether the workpiece has been accommodated in the regular position of the mold, accurate detection can be made even if the machining surface of the mold is curved. ■ Since it is detected via a swing lever, it can be detected even if the workpiece is not a magnetic material. ■ Since the rotation axis of the J1 movable lever is movable, errors in the length of the workpiece in the detection direction can be absorbed within the movable range of the rotation axis. 4.
