Description

The invention relates to a punching machine and a working platform for the translational movement of this punching machine, wherein a relative to a mounting plate movable platform can be moved and moved to the punching position after the user has used the workpiece, so that the safety can be guaranteed.

The danger of operating the punching machine is high. To avoid squeezing the user's fingers, a security device is used. From the Taiwanese patent M394404 From 11.12.2010 a safety device for a punching machine is known, which comprises a sensor which is arranged at a suitable location of the platform of the punching machine. The coupling rod of the pedal is connected to a pneumatic cylinder. By a controller a locking rod for the coupling rod is inserted and ejected. When the sensor detects the user's hand, it sends an appropriate signal to the controller, which thus pulls out the locking bar through the pneumatic cylinder to lock the coupling rod. If the sensor does not detect a user's hand, it sends a corresponding signal to the controller, which thus inserts the locking bar through the pneumatic cylinder, thereby releasing the coupling rod so that the user can depress the pedal.

The sensor is formed by a photodetector. The sensor increases the manufacturing costs. In addition, when using the sensor, there may be a blind spot. Therefore, the safety of the user can not be guaranteed.

The invention has for its object to provide a punching machine and a working platform for a translational movement of this punching machine, which can overcome the above-mentioned disadvantages of the conventional solution.

Further, a second power source is provided, which has a second push rod, which is connected to a coupling rod, wherein the second power source is connected to a pedal switch, through which the second push rod can be pulled out. A control unit is electrically connected to the first power source, the pressure switch, the first key switch, the second key switch, the second power source and the pedal switch to control these.

Further, a punch holder is provided, on which an upper rod is provided, wherein the first key switch is arranged on the lifting path of the upper rod of the punch holder.

On the mounting plate rails are provided, for which the movable platform has a slider.

The movable platform can be displaced with respect to the mounting plate in the longitudinal direction, transverse direction or oblique direction.

The first and second power sources are each formed by a pneumatic cylinder.

The invention further relates to a punching machine, comprising: a machine table having a mounting plate on which a drive is arranged, which is controlled by a clutch, wherein when the drive is coupled, it drives a punch holder, which is thus lowered, wherein on the punch holder an upper rod is provided; a movable platform slidably mounted on the mounting plate, movable relative to the mounting plate and having a push rod; a first power source disposed on the machine table, having a first push rod connected to the movable platform, and electrically connected to a pressure switch through which the first push rod can be inserted, the first power source continuing with a first push switch and a second pushbutton switch, wherein the first pushbutton switch is arranged on the lifting path of the upper rod of the punch holder and through which the first push rod can be pulled out, wherein the second pushbutton switch is arranged on the movement path of the push rod; a second power source disposed on the machine table and having a second push rod connected to a coupling rod capable of controlling a clutch, the second power source being connected to a pedal switch through which the second push rod can be extended; and a control unit on the machine table is arranged, with the first power source, the pressure switch, the first key switch, the second key switch, the second power source and the pedal switch is electrically connected to control these.

Like from the 1 . 2 and 3 can be seen, the invention comprises a machine table ( 1 ), a mobile platform ( 2 ), a first power source ( 3 ), a second power source ( 4 ) and a control unit ( 5 ).

The machine table ( 1 ) has a mounting plate ( 11 ), on which two opposite rails ( 12 ) are provided. On the machine table ( 1 ) is a drive ( 13 ) arranged by a coupling ( 14 ) is controlled. If the drive ( 13 ), he drives a punch holder ( 15 ), which is thus lowered to perform the punching work. On the punch holder ( 15 ) is a top bar ( 16 ) intended.

The mobile platform ( 2 ) is slidable on the mounting plate ( 11 ) of the machine table ( 1 ) and can with respect to the mounting plate ( 11 ) are moved. The movable platform ( 2 ) has according to the rails ( 12 ) a slider ( 21 ) running along the rails ( 12 ) in the longitudinal direction (or transverse direction or oblique direction) can be moved. At the rear of the movable platform ( 2 ) is a push rod ( 22 ) intended.

The first power source ( 3 ) is on the machine table ( 1 ) ( 4 ) and formed by a pneumatic cylinder. The first power source ( 3 ) has a first push rod ( 31 ) with the movable platform ( 2 ) is connected to the movable platform ( 2 ) in the longitudinal direction. The first power source ( 3 ) is equipped with a pressure switch ( 32 ) electrically connected by the first push rod ( 31 ) can be inserted. The first power source ( 3 ) continues with a first pushbutton ( 33 ) and a second push-button switch ( 34 ) connected. The first pushbutton ( 33 ) is on the lifting path of the upper bar ( 16 ) of the stamp holder ( 15 ) and can be actuated by the upper bar, whereby the first push rod ( 31 ) is pulled out. The second push-button switch ( 34 ) is on the path of movement of the push rod ( 22 ) arranged and can from the push rod ( 22 ) are actuated, whereby a drive signal is generated.

The second power source ( 4 ) is on the machine table ( 1 ) ( 5 ) and formed by a pneumatic cylinder. The second power source ( 4 ) has a second push rod ( 41 ), which with a coupling rod ( 42 ), whereby the coupling ( 43 ) can be coupled. The second power source ( 4 ) is equipped with a pedal switch ( 43 ) connected to the drive signal from the second pushbutton ( 34 ). When the pedal switch is stepped on, the second push rod ( 41 ).

The control unit ( 5 ) is on the back of the machine table ( 1 ) and with the first power source ( 3 ), the pressure switch ( 32 ), the first key switch ( 33 ), the second key switch ( 34 ), the second power source ( 4 ) and the pedal switch ( 44 ) are electrically connected to control them.

When using, as in the 1 . 3 and 4 is shown on the punch holder ( 15 ) a stamp (A) arranged. On the movable platform ( 2 ) a die (B) is attached. The movable platform ( 2 protrudes from the mounting plate and is not under the punch (A) of the stamp holder ( 15 ). Therefore, the user can manually insert the workpiece into the die (B). After that, the user can switch the pressure switch ( 32 ), causing the first push rod ( 31 ) of the first power source ( 3 ) under control of the control unit ( 5 ) is inserted ( 6 ), so that the movable platform ( 2 ) opposite the mounting plate ( 11 ) is displaced in the longitudinal direction. When the first push rod ( 31 ) is fully inserted, pushes the push rod ( 22 ) at the rear of the movable platform ( 2 ) the second push button switch ( 34 ), which sends a signal to the control unit ( 5 ), which thus the pedal switch ( 43 ). This is the movable platform ( 2 ) under the punch holder ( 15 ) and the punch (A) aligns with the workpiece in the die (B). When the user presses the pedal ( 43 ) ( 7 ), the pedal switch ( 43 ) a signal to the control unit ( 5 ), whereby the second push rod ( 41 ) of the second power source ( 4 ) under control of the control unit ( 5 ) ( 8th ), so that the coupling rod ( 42 ) the coupling ( 14 ) with the drive ( 13 ) couples. By the drive ( 13 ) the punch holder ( 15 ) lowered ( 9 ), so that the punch (A) punches the workpiece. When the punch holder ( 15 ) and the upper bar ( 16 ) the first key switch ( 33 ), the first key switch ( 33 ) a signal to the control unit ( 5 ), whereby the first push rod ( 31 ) under control of the control unit ( 5 ) is pulled out so that the movable platform ( 2 ) opposite the mounting plate ( 11 ) is displaced in the longitudinal direction. This places the movable platform ( 2 ) again not under the punch (A) of the stamp holder ( 15 ). Therefore, the user can manually insert another workpiece into the die (B). The punching work can be carried out cyclically, whereby the safety of the user can be ensured.

The foregoing description represents only a preferred embodiment of the invention and is not intended to serve as a definition of the limits and scope of the invention. All equivalent changes and modifications are within the scope of this invention.
