Patented in the German Empire on March 2, 1934

The invention relates to machines for processing drawn cans. the known machines have a tool carrier that always moves in one direction with one or more tools driven by their spindles. The workpieces are slanted from a to the plane of movement of the tool is removed and fed to the Counter tool introduced for processing. After machining, the workpieces are ejected again automatically. Tools and counter tools are known to the people Machines designed as beading and / or flanging tools. Subject of the invention it is that the machine is provided with tools and counter tools, which are also designed as trimming tools of the same type. A merit of one like that trained machine consists mainly in, that considerably higher working speeds than can be achieved with the previously known machines.

In the drawing, an exemplary embodiment of the invention is shown, namely shows Fig. Ι a cross section through such a machine with a moving tool carrier and combined beading and cutting tool, Fig. 2 the view of the cut tool holder without tools. Fig. 3 shows a section through a workpiece inlet with a can shown in dashed lines engaging tool, Fig. 4, the same workpiece inlet in view with also dash-dotted workpiece. Fig. 5 is a profiled for the purpose of beading Counter tool in the form of a rail with the rolling tool drawn in, Fig. 6 Counter tool for trimming, also in the form of a rail, and Fig. 7 a cross-section by such rail-shaped counter tools for beading and trimming with associated Tool.

α means - such a tool carrier in the form of a disk, which is on the driven shaft b by 'wedge ο. Like. Is attached, c is the mounted in α , driven by drive d tool spindle, e is a fixed, non-rotatable gear. At the lower end of the tool spindle c sit the tools, in the present case the beading tool / which has a roll shape. / is a rail-shaped sinking tool (see Fig. 5), which is mounted and held in the counter-tool carrier 1, which is also designed as a bearing. The rail-shaped trimming tools would also have to be stored in the same way, g is a drive pulley which is also firmly mounted in I and is formed as a circular ring cutout, one end of which is for the purpose of the workpiece inlet, as can be seen in Fig. 3, in is bent at an acute angle. m is an expedient am

Claims (6)

Counter-tool carrier l fastened, inclined! Incoming workpiece inlet channel, the finger-like lower extension of which is curved in a crescent shape and consists of angle iron to guide the workpiece. If the disk a is now set in rotation, the drives d roll on the gear wheel e and move the tool spindles c and thus the roller-shaped tools located on them, in this case the beading tool /, in the manner indicated by the arrows in Fig. 5 in motion, in such a way that the latter roll on the rail-shaped counter-tool. The workpieces are fed through the inlet m, which is inclined to the plane of rotation of the tools, or roll under their own weight into the path of the moving tools, so that the tools reach into them, grasp them, center them, guide them in front of the counter-tool and process them by rolling on it . Another possible embodiment is that the tool and the counter tool are designed in the shape of a roll or a circular ring, which type of tools are known per se. However, in order to enable a uniform movement of the tool carrier α in this embodiment as well, the counter tools are rotatably mounted on the same tool carrier or on a tool carrier that moves the counter tools parallel to the path of the tools while the workpieces are being machined. Another type of design is that the counter-tools, which are designed in the form of a roll, are rotatably mounted, so that the workpieces are brought up to the counter-tools for machining by the tools in a jerky movement Other embodiments are possible. However, the essence of the invention is that the +5 machines used for processing drawn cans with moving tool carriers, namely moving in one direction, which are provided with beading and / or flanging tools, also with trimming tools and trimming counter tools be provided. ΡλtextaνprüchE: 1. High-performance machine for processing drawn cans with a tool carrier always moving in one sense of direction, one or more driven by their spindles Tools are arranged that the workpieces from an oblique to the plane of movement Remove the feed from the tool and attach it to the counter tool for processing and automatically ejecting it again after processing, whereby the tools and Counter tools are designed as beading and / or flanging tools, characterized in that that the tools and counter tools are also used as trimming tools are of the same type. 2. Machine according to claim 1, wherein 'the counter tool is a for Represents beading and / or beading formed rail, characterized in that this rail-shaped counter tool is designed as a trimming tool. 3. Machine according to claim i, characterized by directly cooperating with the tools, also roller-shaped and counter-tools that are driven and mounted in the same way as the tools. 4. Machine according to claim 1 and 3, characterized in that the roller-shaped Counter tools arranged on the same tool carrier as the tools are. 5. .Machine according to claim ι and 3, characterized in that the roller-shaped counter-tools on one with to the. Tool carrier during machining, counterwork eye carrier moving in parallel are arranged. 6. Machine according to claim 1, 3 and 5, characterized in that the roller-shaped, are arranged on rotatable counter-tools on a stationary counter-tool carrier, the Workpieces from the tools stored in the tool carrier in jerky motion be brought up to the counter tool in only one sense of direction. 1 sheet of drawings
