Abstract
ABSTRACT OF THE DISCLOSURE
In an automatic punching and bending machine the interspace between the bending device and the punching device is adjustable in order to make the interspace as small as possible and to adjust that interspace in dependence on the length of the working piece of a band material, thereby gaining the advantages that series of different work pieces of high precision can be produced in the same machine. The bending device is re-movable and can easily be replaced by another one which has been reset in a preceding working process. Therefore stillstand periods of the machine are reduced.

BACKGROUND OF THE INVENTION
... ~ . . _ .. . .. .
The present invention relates to an au-tomatic punchiny and bending machine for the production of multi~form small parts from metal band or wire comprising a draw-in system for the band or wire, a punching device and at least one bending device, the bending device consisting o~ a plurality o~ slide units each provided with a bending tool~ the slide uni-ts being arranged around a central working station, a central driving mechanism for driving the plurality o bending tools, the punching devic'e and the draw-in s~stem.
In known punching and bending machines of this kind the punching device and the bending device form a construction unit with a fixed space between one another. This space is large with respect to the lonyitudinal dimensions of the small parts to be produced. Difficulties ~rise with respect to the exact transport of the small work pieces between the punching device and the bending device if different series of small work pieaes are to be produced in the machine.
One object of the invention is to'~rovide a punching and bending machine which can be ças ~ reset or adapted for the production of diferent work'pi~ces.

The automatic punching and bending machine mentioned above is improved in that the punching device and the bending device being displaceably arranged relative]y to one another in the feeding direction of the band or wire material and being adj~stable with respect to the longitudinal dimension'of the small parts.
The present invention has the advantage that the punching device and the bending device can be arranged with a small spacing such that only, one or a few work pieces have place between them. In contrast to the known machine the sum of the unavoidable inaccuracies i~ the length of the work pieces is remarkably less and it is ensured that each working piece comes into an accurate position within the bending device. The maahine according to the invention can easily be adapted for the pr~duction of working parts b different dimensions. The spacing between the punching device and the bending device can accurately be adjusted with respect ~o the longitudinal dimension of',the work pieces. Therefore the degree of accuracy of the produaed work pieces is greater and the machine can be used with a higher versatility, because ver~ small wOrk pi~ces can be produced as well as bigger ones.

A further important feature of the invention lies in that the bending device as a whole is removably and exchangeably arranged with respect to the punchiny device. Thereby the advantage is yained that the machine can be operated to produce bent metal articles while at this time another bending clev.ice can be prepared for the production of different articles.
Then the bending devices need only be exchanged and after the new device having been adjusted with respect to the length o~ the articles to be produced the machine can be started again. The standstill pexiods are reduced and the util:Lzati.on ~actor of the machine is increas~d.
A further ~eature of the invention lies in that a moving track of the bendiny device or punching device is o~fset in a direction parallel to the axis of a central wh~ of the bending device by an amount that the bending device and/or the punching device can be moved into relative positions overlapping one another in the feed~ng direction of the band or wire material.
By this overlapping the smallest possihle spacing between the centre of the bending device and the centre of the punching device is gained. Addording to a first alternative the bending device can be moved longitudinally behind the punching device and in the case of a horizontally arranged main wheel or central wheel of.the bendlng device a second alternativ~e consists in that the bending deviae is movable into a po.~tion at least part,ly beneath the punching device. For this purpose the punching device can be arranged on a blind case, which is removable to provide place ~or the bending device.

DESCRIPTION OF THE PREFERRED EMBODIMENTS
.
FIGURE 1 shows schematically an automatic punching and bending machine 10 which comprises a machine base 12 on which are mounted a draw-in system 14, a pumching device 16,and a bending device 18. The lakter has a central wheel 20 on which are mounted a plurality of radially arranged slide units as known (not shown) each supporting a bending tool. Th0 machine base 12 is provided with a slide guide rail arrangement 22 (FIGURE 3), extending in the longitudinal direction of the base 12 and by means o~ which the bending device 18 is displaceably guided in the directions of the double arrow 24, from a position shown in ull lines into a position shown in do.tted lines. In the first position the bending device 18 as a whole is spaced rom the punching device 16 whereas in the second position the bending device has been moved in the direction of the punching device by more than half of its length~ thereby having reduced the i.nterspace between the axis of the bending device and the centre of the punching device.
Because of the transverse of~set between the bending and punching dévices shown in the lower part of F~GURE 1 the bending device 18 and the punching device are in overlapping condition and the bending device lies partly behind the punching device.
.
The interspace between the bending and punching devices is chosen as s'mall as possible dependent on the length of the work pieces to be produced that means dependent on the pitch of the band or wir~ material.
~2~ S5~
The automatie punching and bending machine 10 has a central driving mechanism 26, the main shat 28 of which drives an eccentric shaft 32 of the punching device 16 or press by means of a chain or belt 30 and also drives the draw-in system 14~
via bevel gears 34. The draw-in system and the punching device are combined as a structural unit, rom which the bending device 18 is separated which is drivingly connec-ted with the main shaft 28 by means of a toothed hollow shaft 36 into which the main shaft 28 is telescopically inserted. ThereforQ the bending device is in driving connection with the main shaft 28 in any of its displaced positions on the machine base.
FIGURE 2 diers from FIGURE 1 i.n that the bending ~evice 18 is fixed on an own base and this unit is removab].e rom the machine as a whole in order to reset the bending device at another place while a prepared new bending device can easily be connected with the machine. While the bending device 12 is fixed on its base, the unit consisting of the draw-in system 14 and the punching device or press 16 is movably supported on the base 12 in the direction of the double arrow 38, i.e. parallely with the feeding direction of the band or wire between a first position shown in full lines and a second position shown schematically in dotted lines in the side view of FIGURE 2. In the plan view below the second po~tion of the unit is shown in full lines in which th0 bending device and the punching device are in maximum lap condition.
~2~7~
FIGURE 3 shows a punching and bending machine in which the punching device 16 and the draw-in system 14 are not modified bu~ a bending device 118 is movably mounted in a transverse direction on a slide 40 which is movable in lon~itudinal direction on the guide rai~s 22. The bendiny device 118 is mounted in a positlon as turned by 90 with respect to FIGURE 1 such that the axis of the central wheel lies parallely with the feeding direction o the band or wire. The telescoplcal toothed shat 36 is connected with a pinion 42 which engages the toothed outer circumference of the central wheel 20.
. . .
FIGURE 4 shows a punching and bending machine having a horizon-tal ben~ing device 218. The axis of the central wheel extends vertically. The punching device 16 is arranged above the base with a vertical interspace equal with the height of the bend-ing device 218. This interspace can be filled by a blind case 44 the height o which corresponds to that o~ the bending device. After removal of the blind case 44 the bendlng device 218 can be moved into the space below the punching device and out of this space in the direction of the double arrows 46.
The largest interspace between the centres of the bending de-vice and the punching device is shown in full lines in FIGURE 4 while the smallect interspace is shown by dotted lines in which position almost half of the bending devioe lies below the punching device 16. The bending dev;ce is driven via a ~el~scopical shaft connection and a bevel gear arrangement.
7~
FIGURE 5 shows the punching and bending machine 10 according to FIGURE 1 with the bending device 18 being in a displaced position near ,the punching device 16 bu~ without overlapping the punching device. The interspace between the axes 48 and 50 marked with dot and dashes is exactly adjuated to the pitch o the band 56 of woxk pisces 52 and amounts accurately two and a hal times the length of a work piece. If the machine i~ to be adapted to work pieces 54 of shorter dimensions the hending device must be moved to the right as shown in FIGURE 6 into a position in which the interspace between the axes 48 and 50 is reduced and corresponds exactly with the pitch o the band o the smal~r work pieces 54. Also in this example this interspace is two and a hal times as large as the length of the work piece 54. Generally speaking the inter-space must be two times, three times, four times and so on as great as the work piece longitudinal dimension plus a half working piece length respectively. The additional hal length is required because the punching`device centre coincides with the middle between two adjacent work pieces whereas the centre o the bending device oincides with the middle o the work, piece itse~.
A main advantage o this invention gained by the displaceable `
arrangement o~ the bending device and the punching device relatively to one another lies in that very small work pieces and remarkably longer work pieces can be produced in the same machine. Further it is advantageous that the machine always operates with a high precision because between the punching 7S~
- 10 - ` :
device and the bending device only a small number o~ work pieces are situated, so that the sum of tolerances is extremely low and the work pieces can be accurately delivered to the centre of the bending device. Last not least it is highly advantageous that the bending de.vice ca.n be ~ully removed from the rest of the machine in order to replace it by anothe.r one which has been reset and adapted to different bending operations in a preceding working process at another working place. The standstill periods of the machine therefore are substantially redu¢ed.
Some modiications aan be made without leaving the scope o~
this i.nventlon.}nstead o having only one bending device 18, 118 or 218 a plurality o bending devices can be arranged in serles.
The machine not only has a draw-in system, a punching device or press,and a bending device but additlonally other working devlces can be inserted into the working process as milling machines, plastic moulding machines and so on. The machine ~urther is not limit.ed operating with a band material bu~ also a row o separate work pieces abutting one on another can be handled.
