The present invention relates to a press slide height adjustment device for storing the height of the press slide and cushion in advance in the memory device for each mold to be worked, and finding the target value by number according to the mold to facilitate the press work.

In general, the press slide height adjusting device is composed of five 7-segments as shown in FIG. 2 and displays the current position of the slide and the cushion to display the current position (1). The controller 3 which outputs a motor drive signal by comparing the target position with the target position setter 2 for setting the target value to which the target is to be moved and the signal input from the start commander 6 and the target position read from the sensor 5. , A motor driving unit 4 for controlling and driving the motor with a signal output from the controller 3, a sensor 5 attached to the motor shaft to read the current position of the slide and cushion by motor rotation, and instructing the driving of the motor. It consists of a start-up instruction section (6) for outputting a signal to the controller (3).

When the operation by the above configuration is explained, the controller 3 always displays the current position read from the sensor 5 via the current position display unit 1, and when the start command occurs in the start instruction unit 6, The target value set in the target value setting unit 2 reads the current position and the target value continuously and transmits signals such as right turn, left turn and brake release to the motor drive unit 4 so that the slide moves to the set target position.

At this time, the motor driving unit 4 receives the above signal and rotates the motor. When the motor rotates, the sensor 5 continuously transmits the changed position to the controller 3 and the controller 3 continues to be input. The position is displayed through the current position display unit (1). In addition, when the output is compared with the target value and closes to the target value, the output of the left / right rotation and brake release is cut off, and the motor drive unit 4 sends a stop signal to stop the driving of the motor to adjust the height of the slide according to the mold type. did.

Since the conventional press slide height adjustment device as described above is to set the number directly through the switch for displaying the number in order to set the target position, and then press the RUN start button to perform the height adjustment It was inconvenient to set the number one by one every work. For example, when the target value is 1,550 mm, there is an operational inconvenience in that the start button must be operated after setting this number one by one.

The present invention has been devised in view of the above-described conventional defects and described in detail based on the accompanying drawings as follows.

The current position display unit 1 composed of five 7-segments, the target value setting unit 2 composed of five digital switches, and the current position and target value read from the sensor 5 in response to the signal from the start-up instruction unit 6; The controller 3 outputs the motor drive signal by comparing the motor, the motor driver 4 for controlling and driving the motor with the signal output from the controller 3, and the current of the slide and cushion caused by the rotation of the motor attached to the motor shaft. The above-described target value setting section 2 includes a press slide height adjusting device composed of a sensor 5 for reading a position and a start instruction section 6 for outputting a signal to the controller 3 as a part for instructing the driving of the motor. Connect the target value display unit (7) displaying the target value to the controller (3), and install the automatic start unit (8) connected to the target value setting unit (2) to memorize the height of the slide and cushion for each mold, and then the number (1 Find and select target values by Easy was ever possible.

Referring to the operation and effect of the present invention, when the automatic command signal is sent from the automatic start unit 8 in FIG. 2, the controller 3 receives the automatic start signal input and enters the number input to the target value setting unit 2. Read and find the target for that number. In addition, the target value display unit 7 displays target values corresponding to a plurality of previously memorized numbers (No. 1 to No. 99). (Indicated by 7-segment in 5 rows)

The target value setting section 2 is constituted by five rows of counter-type digital switches. The target value setting section 2 can directly input a numerical value as in the prior art, and can also use a plurality of numbers (from No. 1 to No. 99) by using the last two digital switches. You can also select a number.

The controller 3 can store up to 99 items ITEM using the TEN KEY.

That is, the controller 3 always displays the current position read by the sensor 5 via the current position display unit 1, and at the same time stores the command of the automatic starting unit 8 using the ten key, and stores the target value at that time. By reading the number of the setting unit 2, the target value corresponding to the number is found and displayed through the target value display unit 7. The slide of the press is automatically moved to the set target position by continuously comparing the current position with the target value.

As such, the present invention can be easily operated by using a previously memorized number to adjust the height of slides and cushions according to the height and type of the mold when the press die is replaced, and shorten the mold replacement time and improve the quality of the press. It is a new design that raised the practical value further.
