3The invention relates to a tool, and in particular a manually operated pressing tool with a ^f inem exchangeable tool head which has a tool part that moves back and forth, *

A pressing tool with a tool head between the guide plates provided at a distance from each other, and has movable tool part, identifies see according to the invention in that the tool head is arranged between the plates and frame-shaped with a guide part for a stamped reciprocating Tool part is formed and interlocking parts on the tool head frame and the main

j part of the tool and the reciprocating part j. and the drive means of the tool are provided, so that the tool head is detachable from the main part of the tool is connectable so that the actuating device of the tool and the reciprocating tool part are connected together, the interlocking parts are thereby disengaged that the Tool head in relation to the main part of the tool in a direction that is transverse to the reciprocating direction of the movable tool part is:,.

An embodiment of the invention is by reference ■ on the figures in. Described in the description below. From the figures show?

Figure .1 is a side view of a manually operable tool according to the invention, with some parts cut away are placed}

FIG. 2 is a partial view similar to FIG. 1}

FIG. 3 shows a plan view corresponding to the viewing line III-III in FIG. 1.

The tool shown in the figures is designed like a pistol and has a main part 1 and a handle 2 and a housing 3 in which an electric motor is located. The engine is with a moving linkage with the end an arm 5 connected. A pin β is at the end of the

When the tool head 9 is attached to the main part 1, as shown in FIG. 1, actuation of the electric motor causes the arm 5 to move and the stamp-shaped part 14 to be actuated, so that the pressing stroke is carried out. The process of changing a work part consists in inserting the part in the die 12 and activating the motor. The common die 15 is then moved by the punch 14 in the direction of the first-mentioned die 12 and the part to be processed is thereby put under pressure and then the punch-shaped part 14 is withdrawn and the workpiece removed. If the Hotor is kept switched on, the assignment of a die 15 is repeated cyclically in the direction of Λ ie.

The part to be machined is too hard or too large, so that then ^: the stamp-shaped part 14 cannot reach its prescribed front position and jams so that it moves neither in one direction nor in another direction. ITm : To remove the Iferfezeugkopf f from the main part 1 of the tool, the pawl 21 is moved around the pin 22 against the force of the Torspannfed & r-23, and then the head 9 is turned slightly counterclockwise in Figures 1 and 2 in a direction transverse to the direction of movement of the stem-shaped leila 14; *: so that the grooves 16, 17 are brought out of engagement with the corresponding pins 6, HS and the head part can be removed between the plates 8.

If the stem 14 has jammed, both. For example, because a full pressure stroke cannot be carried out, it is generally not possible to get the tool free again without completely dismantling it. In the case of the tool according to the invention, the motor is put out of action and the screw 24 is quickly screwed so that it protrudes from the protruding part 20 and acts against the bottom of the recess 19 in the event of a jam. If you then turn screw 24 further, the previous

jumping rope 20 is pushed out of the recess 19, and the pawl 21 can be folded back and the head part 9 can be separated from the main part 1 of the tool, as described above. It should be noted that if the tool jams, the tool parts are under high stress _? so that the pawl 20 cannot be lifted by hand, even using a lever-like instrument. '

The invention has been made in the context of a manually operable Tool described, but the invention can also be applied to tools on a workbench are mounted and are not operated by an electric motor but, for example, by hand.

A lever mechanism that ensures that a complete. Duty cycle must be carried out before the pressure dies apart is described in U.S. Patent 2,618,993.
