For punching sheet metal for ships, gas and water containers, etc. have been previously Punching with one or more punches used, which the sheets in horizontal punched in the stored state. The rows of holes were divided either by marking out manually or horizontally arranged sub-devices.

The sheets were either on one

ίο block and tackle etc. suspended in chains or clamped to a carriage rolling or sliding on a horizontal track. Usually the punch is arranged on a longitudinal side of the clamping carriage.

Since z. B. for container construction, etc. the sheets on all four sides with rows of holes for the Rivets had to be provided, so it was necessary after completion of each row of holes to loosen the sheet metal, to turn it over and to fasten it again, or to avoid the latter one had to use the clamping carriage and the dividing devices not only along the punch but also across it displaceably arrange, which is especially true for punching for heavy sheet metal plates expensive designs that resulted in the economics of the machine being called into question became. The space requirement of such a machine is also very considerable and the system is usually confusing.

According to the present invention, there is a substantial simplification in processing achieved such sheets. The same is essentially characterized in that the vertically placed sheets are supported by clamping brackets, their adjustment both takes place in the horizontal as well as in the vertical direction after the division of partial rails. After triggering the locking of the sub-devices. Organs can punch made at any point in the sheet regardless of the sub-devices will. The punch is also arranged vertically.

This makes it possible to have all rivet holes on metal sheets in every pitch to be attached in longitudinal as well as transverse rows without reclamping or tearing the Sheet metal is required.

In the accompanying drawings, an embodiment of the device is in connection shown with a punch, in which the punch in the horizontal plane work.

Fig. 1 is a front view and Fig. 2 is a section along AB.

The running rail holders b, balanced by counterweights, slide on one of the required number of guides a of the greatest sheet metal lengths. The latter are moved up and down in the vertical direction by the spindles c, the conical wheels d and the common shaft e , by hand by means of the hand chain g, worm and worm wheel f or by an electric motor h and the like by means of the belt i.

The rollers m, which are connected to clamping brackets η, run on the running rail k. The latter, however, are connected to one another by a common rail 0 , which

is provided with stops ρ corresponding to the hole pitch and are each supported against a locking pin q arranged on the running rail k. This locking pin can be disengaged from the stops ρ by means of a pulling element r. The sheet metal 5 to be perforated is carried by the clamping brackets η and can be moved back and forth on the running rail k by an endless hand chain t. For this purpose, the chain 11 is guided over pulleys u u 1, which is looped around the cable drum ν on the rear side. The latter, however, also has a second pulley n>, which by means of the chain n> 2 transmits the movement to a pulley w l. This pulley iv * is combined with a drum »'3 and can turn on the pin x, which is attached to a support χ', when the cable drum ν sitting on the same support is set in rotation by the chain t. A rope s l is looped around the drum n> & which is attached to both ends of the partial rail ο. As can be seen from FIG. 2, any running rail carrier b is provided with a vertical part-rail o1, which can be triggered by a locking pin ^ 1 by means of the pulling element r1. The device is intended for dividing the vertical rows of holes that are divided by the dividing rail o1. To <; A clutch y is switched on somewhere on the common drive shaft e. The latter is moved by the linkage \ \ J in such a way that either the worm wheel f is engaged, whereby the manual transport is switched on, or the friction clutch γΎ is engaged, which causes the motor h to be switched on. This activates the mechanical adjustment. A platform ρ * is arranged on the punch s2, which can be provided with one or more horizontally operating punches ss, which is intended for the person operating the device so that the entire mechanism can be completely monitored from this central point. The mode of operation is as follows: The punch s2, single or multi-stamp, is vertical. At ρ 'is the position of the worker operating the machine, who can completely control the entire mechanism from here and observe the work of the punch without having to change his place. The process of punching is as follows: The sheets s planed at the edges are brought between the recess ii2 of the punch s2 and placed on the plate jpi, which lies parallel to the running rail k on the floor. If the running rail k is now lowered so far that the clamping blocks η grasp the sheet metal at the upper edge after tightening the clamping screws, the sheet metal is not only firmly clamped, but also precisely aligned at the same time, so that the rows of holes that are created run exactly parallel to the sheet metal edge . It is not necessary to draw the division on the sheet, only the first hole in a row of holes is punched. The partial rail 0, which can be adjusted on the clamping brackets η, is now fastened in such a way that the locking pin q rests against the first stop ρ when the punch of the punch is on the first hole. The worker now puts the punch into operation and, after each stroke of the punch, moves the sheet metal to the next stop on the dividing rail. When using precise dividing rails, holes or distribution are not possible. Since the punch holder of the punch is rotatably arranged, when several punches are used, the latter can also stand one behind the other in the vertical direction and thus vertical rows of holes can be punched in the same way by means of the partial rail 0 'and the locking pin q1. The locking pin ql can be triggered automatically as soon as the drive for the height adjustment is switched on. This prevents a possible machine breakdown if the worker is careless. If both locking pins q and q1 are triggered, individual holes can be conveniently punched at any point in the metal sheet without further turning, since the metal sheet can be set to any desired point quickly and easily. Due to the vertical installation or suspension, a significant saving of space is achieved, especially on the floor surface, since the device can be attached to the wall or to the iron structure of the building.
