The present invention sets pressure using zone proportional valve, variable resistor and amplifier in order to display the molding pressure of press for molding the cooling aid to proper pressure, and the bias load of the press during the molding process is the indicator of pressure gauge. Segment). That is, when the press is started and the slide starts to form the material, the maximum pressure (MAX) and the minimum value of the punch load set in the pressure gauge at the same time that the current load is transmitted by the pressure sensor to the pressure gauge and displayed as 7-segment It has been operating a system that stops the press and outputs an alarm signal outside the (MIN). Therefore, the operator has used the machine operation method of operating the press after adjusting the pressure lower or higher than the existing one, but the operation method of such a press cannot accurately judge whether the punch load during molding is accurately transmitted and the punch for each slide position The load was unknown and there was an inconvenience in keeping proper punch load by hand. (Difficulty in data management)

The present invention, in view of the defects of the conventional press forming apparatus as described above, the pressing force is stored in accordance with the press slide position when forming the cold forging, and then printed to determine whether the molded by the appropriate pressure and at the same time digital switch By setting the position of the slide and the upper and lower limits of the pressing force, it is possible to obtain convenience of use and cost reduction effect.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

When the pressure is input, the molding pressure is determined by the set value of the digital switch. The main control unit 104 includes slide position management for the digital switch (DS1) (DS2) and slide switch pressure control (DS3) (DS4). Is connected, and through the controller 101, 103, the position detection sensor 100 for detecting the slide position and the pressure sensor 102 for detecting the pressure at the time of molding are connected.

On the other hand, a data output device is connected to the output side of the main controller 104 as shown in the example of FIG. 2. The data output device includes a print controller 106 and a micro printer 107 provided with a push button 105 for a print command signal. It is composed.

Referring to the operation of the present invention exhibiting such a configuration, first, by operating the digital switch (DS1-DS4) to set the slide position and the upper and lower hinges of the molding pressing force and the press is activated, the position detection sensor 100 slides The position is sensed and the position detection signal is converted into a binary binary signal by the controller 101 and transmitted to the main control unit 104 which manages the molding pressure.

The main controller 104 then stores the position detection signal value and the pressure detection signal value in the internal memory element by a predetermined control program.

On the other hand, when the print command signal is applied by the operation of the push button 105, the printer controller 106 reads the slide position data and the molding pressure data stored in the internal memory element of the main controller 104, and prints a predetermined print pocket. The program is transmitted to the micro printer 107 according to the program, and then the micro printer 107 outputs the molding pressing force according to the slide position to the outside.

Then, the operator can read the printed data and accurately determine the presence or absence of the immortality of the cold forged molded product.

In other words, pressure control can be carried out in units of 0.1 mm for fine parts having a molding stroke of 3 mm, so that it is possible to accurately determine whether or not the product is dirty.

In other words, pressure control can be carried out in 0.1 mm units for fine parts having a molding stroke of 3 mm, thereby accurately determining product defects, thereby achieving cost reduction effects, and further improving quality and technology.
