The present invention is designed to control the punching operation continuously in the state of stepping on the driving foot when the material is punched in the press machine, and the auxiliary control device is connected to the driving step by the upper part of the moving clutch. It can be configured to operate so that the punch can be punched by a single stroke instead of continuous operation even when the driving step is stepped on, thus preventing the safety accidents caused by carelessness when the material is punched and improving the working effect. The safety device of the press machine.

In the conventional press machine, when punching the material with a punch, once the power is turned on, when the driving motor is driven and the driving force is transmitted to the general connecting device, the driving step is pressed down. The moving clutch held by the locking piece fixed at the upper end of the lock is released and at the same time, the sprocket is engaged with the sprocket of the general connecting device which is driven while moving to one side, and the punch is punched by the usual method. In this state, the punch was continuously operated in the state of continuously depressing without depressing the driving step, so the worker punched the material once and then kept pressing the step in some cases. Remove the punched material, or remove the There was a drawback that many safety risks were inadvertently carried out when attempting to settle on a work platform for work.

Therefore, the present invention is devised to solve these conventional drawbacks, and the configuration will be described below with reference to the accompanying drawings.

The sprocket 4 is fixed to the end of the motor shaft 3 of the drive motor 2 installed on the rear surface of the press main body 1 so that the sprocket 4 and the sprocket 4 'are connected by a chain 5. On the sprocket 4 ', the rotating roller 6 and the rotating shaft 8 into which the moving clutch 7 is inserted are fixed, and an elastic spring 9 and 9 between the rotating roller 6 and the moving clutch 7 surface. ') The key insertion grooves 10, 10' and the keys 11, 11 'are respectively positioned and combined with each other, and the guide jaw 12, 12' protrudes from the surface of the movable clutch 7. And the latching jaw 16 and the insertion surface of the movable clutch 7 and the sprocket 4 ', respectively, while being caught by the movable clutch engaging piece 15 at the top end of the plurality of connecting rods 14 of the driving scaffold 13. The groove 17 can be formed to be mutually organically engaged or dismantled, and then, on one side of the upper plate of the press main body 1, interconnected fixing bodies 18 and connecting bodies 19 are formed by the fixing plate 20. The support rod 22 into which the locking rod 21 is inserted into the front lower portion of the fixing body 18 is connected and fixed to the guide rod 24 inserted into the guide guide groove 23 drilled before and after. In addition, the elastic spring (9 ") is built in the outer periphery, and the spring (9" ') is installed in the spring insert (25) of the fixed body 18, the connecting rod (26) connected to the movable clutch engaging piece (15) ) Is inserted, and the fixed rods 28 and 28 'to which the adjusting pieces 27 and 27' are attached to both sides thereof are fixed. The reference numeral 6 'is a rotary roller and 29 is Punch and 9 "" are springs.

Referring to the effect of the present invention configured as described above are as follows.

In the safety device of the press machine of the present invention assembled as described above, by installing the safety device so as to be able to operate organically with the driving footrest 13 directly on the upper portion of the moving clutch 7, the stepping foot 13 is stepped on. The punch 29 can be controlled to perform a single stroke even in a state where the driving motor 2 is driven when the power is turned on in a state in which the material to be molded is in contact with the base of the press main body 1. As the driving force of the drive motor 2 is transmitted through the motor shaft 3, the spotket 4 is rotated, and then the spotket 4 'is also rotated. When 13) is pressed down halfway as shown in FIG. 5, the latch of the moving clutch catching piece 15, which has been caught on the guide jaw 12 surface of the moving clutch 7 surface, is released and at the same time the rotating bowler. 6 and moving clutch The insertion groove 17 formed on the sprocket 4 'surface which is rotated while the moving clutch 7 moves to the right direction by the elastic force of the elastic springs 9 and 9' which are coalesced between the seventh and the seventh springs. ) And the insertion jaw 16 of the movable clutch 7 are interlocked so that the movable clutch 7 rotates, and then the keys 11 and 11 'of the movable clutch 7 become the key of the rotary roller 6. Inserted into the insertion groove (10) (10 ') is rotated together, and then the driving bar 13 is in a fully stepped state as shown in Figure 6 connecting rod 26 and the moving clutch engaging piece 15 connected thereto The guide guide rod 24 in the guide guide groove 23 is guided by the adjusting piece 27 fixed to the end of the fixed rods 28 and 28 'fixed to the connecting rod 26 at this time. As the lowering along the guide groove 23, the engaging rod 21 connected to the guide rod 24 is engaged with the guide jaw (12 ') of the movable clutch (7). The movable clutch 7 is released from the procket 4 'surface, which is the state in which the operation of the punch 29 is stopped once the movable clutch 7 is rotated once and the punch has completed the single-shot operation. . Subsequently, when the driving pedal 13 is released, the moving clutch catching piece 15 is moved to its original position by the spring 9 "" of the driving pedal 13 surface, and at the same time, the adjusting pieces 27 and 27 ') Is mutually organically operated so that the guide bar 24 in the guide bar guide groove 23 is constantly transferred and adjusted, so that the locking bar 21 fixed thereto is moved upwards accordingly. The moving clutch catching piece 15 is caught by the guide jaw 12 at a predetermined interval before the latch of the catching rod 21 is completely released from the guide jaw 12 'of (7). When the material can be punched out with a punch while repeating the operation as described above, and the pins which have respectively attached the middle portions of the fixing rods 28 and 28 'are released as necessary, the fixing rods 28 and 28' Fixed rods 28 and 28 'to which the adjusting pieces 27 and 27' are fixed, separated from each other back and forth. Since the front part is separated from the connecting rod 26, the guide rods 24, the support rods 22, and the locking rods 21 which are organically interlocked by the adjusting pieces 27 and 27 'do not operate, and the moving clutch locking pieces Since the movable clutch 7 is operated only by (15), in the state where the driving pedal 13 is stepped on in this state, it is possible to work with a single shot rather than a single shot. The unit part, the driving step, and the moving clutch locking piece can be linked to each other organically so that the single step operation of the punch can be performed while the driving step is pressed. It is a very useful design that can improve workability.
