Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a press gauge with a sensor.

(Prior Art) Conventionally, for example, at the time of press work for drawing (drawing press), a press gauge with a proximity switch has been used for detecting and determining whether or not a material to be processed is put and proper setting is possible. ing.

For example, as shown in FIG. 5, the conventional press gauge has a hinge mechanism 3 on one side of an upper end portion of a gauge base 30 in an upright state.
The guide lever 32 is provided so as to be rotatable in the vertical direction via the guide lever 1, and the magnetic sensor 33 is operated by the downward rotation operation of the guide lever 32 in the arrow (a) direction.

That is, the guide lever 32 is composed of an angle-shaped member as shown in which the upper piece 32a and the lower piece 32b are bent in a substantially right-angled direction. It is maintained in a tilted state. In this state, the masking plate 35 does not correspond to the sensing surface 33a of the magnetic sensor 33, and the magnetic sensor 33 does not operate.

However, when a predetermined material (workpiece) is introduced from above, the guide lever 32 is guided by the descending movement of the material and rotates to the state of the imaginary line in the figure, and the masking plate 3
5 masks the sensing surface 33a of the magnetic sensor 33 by a predetermined area. As a result, the magnetic sensor 33 operates to detect the input of material. Reference numeral 36 is a stopper, which is an inclined portion 36a for guiding and dropping the material downward.
And a positioning portion 36b that finally regulates the lateral position of the material dropped through the inclined portion 36a.

That is, in this case, the sensing surface 33a of the magnetic sensor 33 is formed in a wide area of a predetermined value, and outputs an ON signal when the masking amount (masking area) by the masking plate 35 exceeds a predetermined set value. To do. Therefore, after all, the setting position of the introduced material can be detected according to the turning angle of the guide lever 32, and the fact that the material has been introduced can be detected and the function as a gauge (particularly a front gauge) can be detected. Is being realized.

(Problems to be solved by the invention) However, in the configuration of the above-described press gauge with a proximity switch, the detection lever portion (guide lever portion) that detects whether or not the material is input and the material is positioned at an accurate lateral position. It is necessary to individually provide three-component parts, namely, a stopper part for regulating and a material receiving part for supporting the material in an upper and lower position where it is easy to press the material, in the periphery of the material end of the die, which requires a large installation place. It has the drawback that Therefore, the structure is complicated, the cost is high, and the adjustment work of the gauge portion has to be performed individually at each location.

(Means for Solving the Problem) The present invention has been made for the purpose of solving the above-mentioned problems, and it is positioned at least at the side of the press die at the time of feeding the material and the material is put on the press die. In a press gauge with a sensor configured to detect each of the input positions, a material receiving portion that receives the input material on the press gauge base, and a vertical rotation above the material receiving portion. A guide lever that is freely supported and that rotates vertically by a predetermined angle according to the end position of the material received on the material receiving portion, and a sensor that operates according to the rotation angle of the guide lever. And are integrated respectively.

(Operation) In the configuration of the press gauge with the sensor of the present invention, the material receiving portion that receives the material put on the press die,
A material is received by the material receiving portion, and at the same time, a guide lever for position detection that rotates according to a receiving position (feeding position) of the material and a sensor that operates according to a rotation angle of the guide lever are provided. However, it is possible to easily detect and determine whether the material is put on the press die and whether or not the material is put into the pressable position.

Moreover, all three of them are integrated on the base.

Therefore, the overall configuration is simplified, and the mounting space and man-hours are reduced. In addition, the gauge position can be adjusted at once, improving the mounting position accuracy and workability.

(Effect of the Invention) Therefore, according to the configuration of the present invention, it is possible to provide a press gauge with a sensor, such as a proximity switch, which is simpler in configuration, assembly, and adjustment than the conventional configuration and is inexpensive. become able to.

(Embodiment) FIGS. 1 to 4 show a press gauge with a sensor (proximity switch) according to an embodiment of the present invention.

First, FIG. 4 shows a schematic cross-sectional structure of a drawing press working apparatus 40 constituted by using the same press gauge. In the figure, reference numeral 1 is a punch type, 2 is a die type,
3 is a material supply line, 4 is a press gauge with a proximity switch that employs a proximity switch as a sensor (front side press gauge with a proximity switch), 5 is a rear stopper, and 6 is a side gauge.

The material (work) 7 is supplied from the material supply line 3 in the direction of the arrow shown in the figure, hits the rear stopper 5, and is dropped to the die face 2a reaching position on the lower punch die 1. Then, the dropped material 7 is first detected by the front gauge 4 as to the fact that the material 7 has been introduced and the position of the material in the front direction, and the side gauge 6 detects the introduced state in the side direction.

That is, the front gauge 4 is, for example, as shown in FIGS. 1 and 2, a base 10 and a material receiver mounted on a side portion of the base 10 via a support shaft 11 so as to be vertically rotatable. 12, a guide lever 14 pivotally attached to the upper end of the opposite side surface of the material receiver 12 through a hinge bracket 13 so as to be vertically rotatable, and an ON operation is performed by the guide lever 14 rotating by a predetermined angle or more. It is composed of a magnetically sensitive proximity switch 15.

The material receiver 12 receives the front end portion 7a of the material 7 on the upper surface of the front end side receiving portion 12a as shown in FIG. A balance weight 12b is provided on the rear end side.

On the other hand, the guide lever 14 is configured by bending the upper balance weight 14a and the lower lever piece 14b in an obtuse angle shape and pivotally supporting the bent portions 16 thereof. Weight 14a and lower lever piece 14b
The weight balance of the above is set so as to be maintained in the inclined state shown by the phantom line in the figure in the state where the material 7 is not supplied. The drop of the material 7 as described above disrupts the weight balance, and
It is rotated in the (a) direction and stopped at the tilt angle position determined by the front direction position of the dropped material 7.

As a result, when the rotation stop position corresponds to a highly accurate position of the material 7 in the allowable front direction position or more, the proximity switch 15 is turned on (due to a decrease in the amount of magnetic gearup). At least, the position in the front direction is detected and displayed to be correctly set.

On the other hand, on the contrary, when the accuracy is less than the above, the proximity switch 15 is not turned on.

The side gauge 6 detects the position of the material 7 in the side direction and detects the position in substantially the same manner as the case of the front gauge 4.

When both the front gauge 4 and the side gauge 6 are turned on and the logical product condition of both is satisfied,
The rear stopper 5 is attached to the air cylinder 2 immediately before the die 2 is hit.
It is controlled by the control panel so that 0 is activated and retracted. Then, after that, the die mold 2 is lowered to perform a drawing press.

By the way, on the front end side of the base 10, the inclined portion 21 for receiving the material 7 first and dropping it while guiding it is provided.
And a positioning portion (length l) 22 extending straight downward from the lower end of the inclined portion 21 is formed, which enables smooth setting on the material receiver 12 and accurate positioning. ing. Also reference numeral 2
Reference numeral 3 denotes a stopper portion that regulates the maximum rotation angle position of the lower lever piece 14b of the guide lever 14 on the front surface side of the base 10 and prevents the contact portion of the sensing portion of the proximity switch 15 from impact. It has the function of ensuring protection.

As described above, in the configuration of the front gauge 4 of this embodiment, the material receiver 12, the guide lever 14, and the proximity switch 15 are all integrated into a single base 10. Therefore,
The structure of the gauge section is simple and the cost is low, and both assembly work and gauge section adjustment work become easier. Moreover, the installation space is reduced, and the restrictions on the space factor are loosened accordingly.
