Press works as follows.

In the process, the profile 18 comes from the roll-forming mill (not shown) in the matrix 17 of the pneumatic press, fixed in a matrix holder made in the form of supports 16 mounted on the lower fixed plate 7 of the movable carriage 6 in the grooves 14. The signal from the electronic control unit 31 is supplied to the air preparation unit 21. Then, from the receiver 20, air enters the upper cavity of the pneumatic cylinder 10. As a result, the piston with the punch 13, made in the form of a knife, moves and cuts into the profile 18. Profile 18 and matrix and 17 with the punch 13 formed as a knife, form a closed system, wherein the translational motion profile 18 is transmitted air cylinder 10. The air cylinder 10 with the profile 18 moving forward on guide strips 3. There felling. Waste from the cabin of the blank profile 18 is discharged into the hole 29, and then into the skize 28 and the container (not shown). The signal from the electronic control unit 31 of the counting device returns the piston with the punch 13 to its original position. The electronic control unit 31 provides synchronous movement of the tape billet 18 and the matrix 17 moving with the movable carriage 6 with the time of punching or perforation of the workpiece by the punch 13 and its return to its original position. Under the action of the springs 26, the mobile carriage 6 returns to its original position. In this case, the limit switch 30 controls the extremely permissible position of the movable carriage 6. The air distributor 22 provides compressed air to the upper or lower cavities of the pneumatic cylinder 10 when a signal arrives at the said electronic control unit 31 during emergency shutdown of the press. In the event that, during a section of profile 18, according to the received signal, the movable part of the mobile carriage 6 together with the punch 13 made in the form of a knife did not stop and continues to move forward, then he presses the limit switch 30 and it works, the profiling line stops emergencyly.

The press is designed to work as part of a line for profiling a metal strip from a flat billet into a section of a given shape. The press refers to technological equipment for separating operations (cutting, punching, cutting, perforation) of sheet metal with a certain step without stopping the line of profiling.

The inventive utility model in comparison with the prototype provides the following technical result:

1. Carries out perforation / cutting of sheet material with a small width of the material of the original workpiece.

2. It has greater productivity compared to a stamp with a movable carriage for separation operations, comprising 12 m / s.

3. It has lower cost in comparison with the stamp with a movable carriage for separation operations.

4. Saves electricity, as it works on compressed air.

5. It is easier to maintain than a stamp with a movable carriage for separation operations.
