In the form of training described here, there are more Measures taken so that irregularly profiled tools can be picked up. The term "profiled" denotes in the following cutting plates and punches with cooperating cutting edges that do not have a circular cross-section.

In Pig. 3, the cutting plate 39 has, for example, an elongated opening. If with profiled stamps and Cutting panels is being worked, it is essential to Take measures to prevent the cutting plate from rotating. According to Pig. 5 is for this purpose a radially extending wedge guide 85 in the bed block 70 provided, which is in communication with the recess 72. Correspondingly, the cylindrical component 73 has a radial one Wedge guide 86 aligned with wedge guide 85; the wedge guides 85 and 86 collectively take one therein by means of a Screw 88 attached wedge 87. These wedges fit exactly together, so that any rotational movement of the cylindrical component "part 73 is prevented about its axis by the wedge 87 cooperating with the wedge guides 85 and 86. Corresponding the upper end of the cylindrical component 73 is provided with a radial wedge guide 89, and the tool or the cutting plate 39 has a wedge guide aligned therewith. A wedge 91 is received from these wedge guides, each of which Angular movement of the cutting plate 39 about the axis of the cylindrical Component 73 prevented. The tool or the cutting plate can be provided with a second wedge guide 92, which is offset by 90 ° with respect to the wedge guide 90, so that the profiled opening is perpendicular to its original one can arrange location. Each wedge guide 90 and 92 runs parallel,

to the axis of the cylindrical component 73 over the entire axial extent of the cutting plate 391 and the displaceable pin 76 can be received by the wedge guide 86 so that the wedge connections described enable the actuation of those described Do not obstruct the lifting device.

In addition to the means for setting these two predetermined angular positions of the cutting plate 39, there is one construction provided, by means of which the cutting plate can be wedged in any desired angular position. To this On the lower tool support and in particular on the cylindrical component 73, the purpose is an upwardly opening one Recess 93 is provided in which a ring 94 lies, on one side of which the wedge 91 is attached. If you have the ring 94 turned around with respect to its position shown in FIG. 5, the wedge 91 is still in alignment with the wedge guide 90, but it does not protrude into the wedge guide 89. After the ring 94 has been turned over, the cutting plate 39 can thus be opened and rotate the ring 94 together with the wedge 91 around the axis of the cylindrical component 73 in any desired position and fix them together with the help of several screws .95. It should be noted that the lifting mechanism also in such a position the Sohnittplatte 39 works in the manner described. Thus you can use different profiled punching tools like this arrange and support that an unhindered vertical removal and replacement with tools of a different shape and great is possible. Since the measuring device is arranged on the table 33, which is mediated by the under-table unit 49 is connected to the frame 31, and there also the Cutting plate 3 9 using the construction of FIG. 5 on

In Fig. 3, the ring 94 is shown with the wedge 91 in your inverted position, in which a definition in any angular position is possible.

If a profiled cutting plate is to be adjustable about a vertical axis, it must also work with it de punch can be adjusted around the same axis. For this purpose, the construction shown in Fig. 6 is used, by means of which the punch and stripper unit in any desired angle » Position can be brought with respect to a vertical axis. The transverse part 41c of the upper tool carrier 41 has an upwardly opening recess 96 in which a flange or Ring section of an annular component 97 is located. Several? Screws 98 hold the upper tool carrier 41 and the annular one Component 97 together to fix the latter in the desired angular position so that it cannot rotate. The stamp and guide unit designated inagesamt with 99 is equipped with wedge connections, which are described below, and the wedge guides with regard to their angular position 90 and 92 correspond to the cutting plate 39; by means of these wedge connections, the punch and stripper unit. 99 is always fixed in its angular position with respect to the annular component 97.

Several stripping springs 105 act between the upper end of the sleeve 100 and a ring 106 surrounding the upper end of the punch actuator 101 and acts together with the stamp actuator on the underside of a stamp head 107. The springs 105 press the Ring 106 up against punch head 107, and screws 108 are used to hold the stripper springs in place. The stripper springs 105 come into effect between the punch actuator 101 and the sleeve 100. There is also a punch provided, the lower end 109a of which has a cross section corresponding to the cross section of the cutting plate 39; that with Internally threaded upper end 109b of the punch 109 is received in the recess 102 and is supported on it the shoulder 104, which forms part of the underside of the punch actuator 101. Through the punch head 107 and The punch actuator 101 extends a screw 110 which is inserted into the threaded hole at the upper end 109b of the punch 109 engages so that these parts move as a single unit. The annular member 97 has an elongated keyway 111, and the punch actuationor.jan is elongated with one of the keyway 111 opposite Keyway 112 provided, the keyways leading at a mutual distance, and between them the Sleeve 1OJ is arranged.

Component 97 is fixed during operation and forms a rigid part of the upper tool carrier 41. A key 113 is fixedly incorporated into a radial opening of the sleeve 100 and its ends protrude radially from the ends of this opening and slip fit on the keyways 111 and 112. Thus, the punch actuator 101 is against angular movement with respect to the tool carrier 101 The punch actuator 101 has a further keyway 114 which runs horizontally along the underside of this element and is aligned with a horizontal keyway 115 in the upper end 109b of the punch 109. Another wedge 116 is releasably connected to the punch actuator 101, for example by means of a screw and so arranged in the keyways 114 and 115 that the punch 109 is secured against angular movement with respect to the actuator 101 so as to maintain the angular position of the punch in accordance with the setting of the annular component 97. Between the annular section 97 of the upper tool carrier 41 and the punch - and scraper unit gat 09 act several lifting springs 117 »to preload this unit as a whole from the cutting plate v / eg. If necessary, a wiper plate 118 can be provided in the lower end of the wiper sleeve 100, which according to Pig. 6 is held in position by a resilient clip 119, ^ hen such a stripper plate is used, it is provided with an opening, the shape and size of which corresponds exactly to the profile of the punch 109, so that the plate is in the immediate vicinity of the circumference of the punch attacks the workpiece. It can thus be seen that the upper tool carrier is also designed so that it can be exchanged and moved up and down as desired.

When the punch 109 and the cutting plate 39 are profiled are, these parts not only have to be aligned exactly to one another, but also their mutual angular position must be determined with relatively great accuracy, so that the game on the circumference of the punch substantially is even. For this purpose, the cutting plate 39 and the punch and stripper unit 99 can be made of their Pull out the brackets and replace them with a lower setting tool 120 or an upper setting tool 121 as shown in FIG. 7. The lower adjusting tool 120 has the same external shape as the cutting plate 39 including a parallel one to the axis of the displaceable component 75 extending keyway 90a, which corresponds to the keyway 90 of the cutting plate 39. the Keyway 90a receives key 91 attached to ring 94.

Correspondingly, the upper setting tool 121 is provided with a wedge 113a, which corresponds to the wedge 113 of the punch and Stripper assembly 99 corresponds, and which is slidably received by the keyway 111 of the annular member 97 will. The lower adjustment tool 120 carries two upwardly projecting adjustment pins 122, and the lower edge or face of the adjustment tool 121 has slightly tapered grooves or recesses 123, 123 for receiving the adjustment pins 122.

than the corresponding outside diameter of the punch unit or the cutting plate device, and the keyway ^f 30a and the key 113a are also dimensioned so that any lateral and rotational movement is substantially avoided. Because of the wedging action between the adjustment pins 122 and the associated grooves or slots 123, as well as the elimination of any clearance, the cooperating adjustment tools 120 and 121 form a rigid assembly which is manufactured with such accuracy that when the annular members 94 and 97 with their Help have been brought into the correct position and fixed, all stamps and cutting plates installed thereafter work together in such a way that there is essentially an even play along the entire circumference of the stamp. It can thus be seen that the setting tools are each received by the ring-shaped components and fixed by the associated wedge connections, and that the tools are equipped with cooperating structures that face each other and only allow common rotary movements of the tools, so that the wedge connections are exactly one on top of the other can align to set the tools.

According to FIG. 8, the connecting section 41c has dee upper tool carrier tick marks 124 on, and the top of the annular component 97 is provided with corresponding graduation marks 12'3, so that the angular position of the annular Components can be displayed in relation to the punching machine and the workpiece table.

According to FIG. 9, an upwardly projecting one can be used instead of these parts attach rigid base 126, in which the shape of the lower part of the shape of the lower end of the cylindrical Component 73 corresponds, so that the base fits into the recess 72 in the same whiteness. As before, takes a keyway 86a on the wedge 97 in order to define the angular position when using profiled cutting plates. According to Fig. 9 is the Cutting plate 127 on the base 126 designed so that the punched pieces of material through a T-shaped opening in in a lateral direction. The cutting plate 127 has two keyways opening in the horizontal direction 128, 128, and the top of the base 126 is provided with a keyway 129 which at one end or the other has a Wedge 130 which cooperates with one of the keyways 128. The wedge 130 is by a screw 131 in his Location held. It can thus be seen that the cutting plate 127 can each be set in one of four angular positions. While the punching machine is in use, the cutting plate 127 can be used by others in conjunction with a base Replace the cutting plates in use. The base 126 preferably has an axial opening so that, if necessary, a Can use retaining screw 132 for the cutting plate.

When the clamping device 42 according to Jig. 13 with the If it is released by hand, the matching construction can be removed or attached to the upper tool carrier. The details the construction for plaguing and loosening go best from Pig. 14 to 16. The clamping device 42 comprises a hand lever 155 with a handle 155a which is rigidly connected to a lever portion 155b, for example by welding. The hand lever is on the leg 31a of the frame 31, the is also referred to below as a component or organ, mounted by means of a lar-; erbqlzens 156 and therefore around a in the present case, the axis running vertically is rotatable. There is also a movable, floating hook 157 provided with a hook-shaped end 157a, which in and can be brought out of engagement with a folding bolt 158, which latter is part of the construction that works together with the clamping device on the upper tool carrier 41 forms. 14 shows how the hook-shaped end 157a engages the retaining bolt 158 and the leg 41a of the tool carrier pushes against the end of a slot in the frame arm 31a. As best seen in Fig. 15, the hook 157 are pushed into a position shown with solid lines, in which the hook-shaped end 157a not only from the Retaining bolt 158 disengaged, but is also displaced relative to the slot of the frame arm so that the arm 41a of the Can remove tool carrier in order to bring it from the position according to FIG. 15 into the position according to FIG.

In order to bring about the described movement of the hook, cam means are provided which between the hand lever 155 and the hook 157 come into effect. In the present embodiment, the cam means comprise cam means a disk-like cam 159 on the hand lever 155 in a suitable manner, for example by means of a screw as shown in Fig. 16. The center of the disk-like cam 159 lies laterally next to the bearing axis of the pin 156, so that the outer edge of the disk-like cam when pivoting of the hand lever 155 is detected. The hook 157 is with its end facing away from the hook-shaped end 157a a recess for receiving the disc-like cam 159 is provided. Thus, the inner surface of the hook forms which this recess forms, in practice, a surface to be actuated by a cam on which the cam 159 engages, to regulate the movement of the hook so that the hook engages the retaining bolt 158 with its hook-shaped end 157a or can release the retaining bolt.

A lock nut 238 is on the outer end of the elongated organ 174 screwed and works with a shoulder 239 of this organ together to the dial button 232 and thus also to clamp the organ 174 in the desired angular position on the table 33. When the lock nut 238 Tightened and the knob 232 is brought to the zero position, the counter 225 must be a zero position or exactly show a specific tenth of an inch. Any deviation in the display of the counter 225 can be compensated for by that one increases or decreases the number of tuning plates 240. The tuning plates 240 thus form suitable means for setting the elongated member 174 parallel to the axis of the lateral guide rails 172 and 173 in the zero position of the counter.

Since the display of the dial 232 and the counter 225 is thus synchronized, these elements show together the distance between the reference surface of the base part 182 and the center line of the punch and the cutting plate. the

The scale button shows the size of the change the counter display. In order to keep all changes positive, so that the reading of the slcale button does not change from the display of the counter needs to be deducted, are two cooperating Pins 241 and 242 provided; the pin 241 is in the table 33a and the pin 242 in the Slcale button 232 installed. These pins come into mutual contact when the rotary knob Jn. Is in a zero position, and they only allow movement of the button in the direction of increasing the display. They attack each other again before the knob can be turned one full turn to the zero position. Thus the display value of the rotary knob is typically limited to the range between zero and 0.098 inches. When the jam nut 238 is tightened axial and angular movement of the button and elongate member 174 is prevented.

In practice, the measuring rail unit 175 has a length of several feet (around 30 mm). It is therefore beneficial to to clamp the measuring rail assembly near its center, i.e. at a point that is approximately behind the punch and the cutting plate, because this is where the force with which the operator applies the workpiece against the unit pushes, cause a slight yield. With regard to the high accuracy of the measuring device according to the invention it is therefore advisable to provide a clamping at the mentioned point in order to maintain this accuracy. An example for such an IC terminal construction is shown in FIG. At a point near the center of the rear guide rail 183

a horizontally arranged component 243 is provided which extends transversely to the longitudinal axis of the guide rail. Of the Table 33 carries a clamping device which engages the horizontal component 143 to the measuring rail unit .175 opposite to set the table. This clamping device comprises a manually rotatable shaft 244 which is arranged under the table 33 and carries a cam 245 rotatable together with the shaft on its rear end. The cam 245 engages on a vertically displaceable pin 246, which in turn serves to press a friction piece 247 from below against the horizontal component 243. Eeibstück 247 extends at right angles to the plains of Pig. 25 and is suitably attached to a guide block 248 at a distance from the pin 246, in which the pin 246 is displaceable and which has an opening for receiving the horizontal component 243. At the front end of the shaft 244 there is a bearing block 249 which is fastened to the table 33 and a 3 lock screw 250 carries, the pointed 3nd of an annular groove 251 of the shaft 244 is added to prevent axial movement of the shaft. The vox'dere end of the shaft 244 carries a handle 252 on the front side of the table 33. In FIG. 25, the one described is Construction shown in the released position. When the handle 252 is pivoted in one direction or another is, the pin 246 moves up to press the friction piece 247 from below against the horizontal member 243 and so to prevent any horizontal movement of the measuring rail assembly 175.

It is obvious that the counter display

with iacncbsn arrangements is sufficiently precise, and that the elongated Organ 174 does not need to be rotated. Under this circumstance, the member 174 could be designed as a rack be.

A stencil scanning device 253 is also displaceable after the rear guide rail 183 and can be moved back and forth as required in order to bring about a movement of the reference surface of the rigid base part 182 forwards or backwards. The scanning device 253 extends above a template 254, which is indicated in fragments in FIG. 1 and in FIG. 3. 26 is shown on a larger scale in cross sectionj this device can act on the workpiece in such a way that the workpiece moves together with the device. Is the work-piece table 33 a little inter-cut near the stamp and the cutting plate _? so that one can arrange a stencil in such a way that il? re 0l5c. ^! ropes lies essentially in the same plane as M: & ifhi-igim parts of the table 33, so that the workpiece can also protrude over the template 254 in some positions. The position of the stencil is determined by guide buttons 255 and BM fflfioL 33 is fastened by a pressure tape 256, the first of which is attached to the adhesive. 257 rests against the top of the table 33; the second pressure-sensitive adhesive surface 258 rests against the underside of the template 254 in a hair-like manner. It has been shown that this type of Scbt.Moneiibefeötigimg is particularly advantageous, because there are no obstacles to the free movement of the stencil holder device or the workpiece guided through it, as has been the case up to now with the various types of Chipmr.ii: teln is the case that reach over the stencil.

It has also been shown that this Yerfabren for fastening of the template 254 is extremely reliable and enables the template to be securely fixed.

The operation of the punching machine is described below using Pig. 27 described. A three phase line 259 leads via a main switch 260 and fuses 261 to certain Contacts of a motor starter 262 and further via thermal triggers 263 to a motor 264, which controls the momentum. wheel pulley 45 constantly drives. A transformer 265 provides a lower voltage for the control circuits

When the start switch 266 is operated by hand, the circuit for the winding of the engine starter 262 is closed, which includes the contacts that open in the event of an overload and a manual off switch 268. By closing the Circuit to the winding of the motor starter 262, its various contacts are closed, to which a Start switch 266 bridging hold contact belongs. With everyone subsequent actuation of the switch 268 is therefore the Open circuit to engine starter to shut down engine 264. Furthermore, on the secondary side of the 'fransformators 265, a socket 269 is connected, which is intended for auxiliary devices, not shown here.

The energy drawn from the transformer ¹ 26p is also fed to a first selector switch 270, which can assume one of two positions. In the position according to FIG. 4, the selector switch 270 supplies the current to a foot switch 271, while the current in the other position of the selector switch

to a switch 272 which forms part of the stencil scanner 253. The other side of the switches 271 and 272 is each connected to a second selector switch 273. In the position of the selector switch according to FIG. 27, the switches 271 and 272 are connected in series with a branch of the circuit in which there are two relays and two switches, by means of which the plunger executes individual strokes. In the other position, the selector switch 273 is connected to another branch of the circuit which causes the plunger to continuously move up and down. As already mentioned, the tappet is connected to the mechanism for generating the upward and downward movement by means of an electrically operated coupling. and this clutch comprises an electromagnetic winding 274. The switches 271, which respond to the position of the clamping devices 42 and 43 and are closed as shown in FIG Solenoid 274 cannot be switched on if one of the clamping devices is only partially released. When the selector switch 273 is in the other position and the actuation switch 271 is closed, the current flows continuously through the electromagnet 274, as long as the actuation BC holder 271 is kept closed. This mode of operation is particularly advantageous for what is known as nibbling. It should be noted that the S'trom for the electromagnet through the holding contact dos motor starter, flows 262 so that not only the engine 264, but also the electromagnet is switched off at 274 Pa ta leagues of circuit breaker 268th Uenn
