Definitions

  • the invention relates to a stamping and bending machine with a plurality of slide assemblies interacting for the non-cutting deformation of wire or tape, each consisting of a base plate which can optionally be mounted in different positions, on which a slide carrying a tool is guided in the longitudinal direction, on which a cam disk rotatably mounted on the base plate or attacks a crank. (see DE-C-2741576).
  • DE-OS 25 27 088 describes driving the carriage assemblies by means of a series of successive gear wheels, one of which drives the next one.
  • the bending center can be moved out of the center of the mounting plate.
  • a disadvantage is the extraordinary load on the gears at the beginning of the drive chain and the resulting high wear.
  • the punch-bending machines differ with freely arranged slide assemblies, for example according to DE-OS 24 35 996.
  • the cam disks of the slide assemblies are driven from a central drive by means of flexible rotary shafts driven or a plurality of cams are combined on a common drive shaft and flexible push-pull cables transmit the stroke movements removed on the cams directly to the tool slide.
  • this type of construction is only suitable for thin wires, since the deformation forces that can be applied are limited.
  • an older German patent application corresponding to the subsequently published DE-OS 35 37 085 is a machine for producing Shaped parts made of wire or strip material with individual slide units are known, the tool slides of which are driven according to a CNC control by means of a tracking-controlled hydraulic rotary vane motor and can therefore carry out freely programmable movements.
  • An electric stepper motor is provided which is connected via a spindle rocker system to a servo valve which controls the pressure medium of the rotary vane motor.
  • the spindle rocker system continuously makes a precise comparison of the angular positions of the stepper motor and the rotary vane motor.
  • the use of the CNC control and the resulting free programmability must be relatively expensive for this machine through relatively complex electrohydraulic control systems for each tool slide.
  • the invention has for its object to provide a stamping and bending machine of the type described in the introduction, in which a high degree of synchronism or the possibility of precise program control of the tool slide and sufficient driving forces can be achieved in a simpler manner and with a correspondingly lower cost.
  • the motors are preferably each mounted on the base plate assigned to the carriage in question. Synchronous running means that not only the same speeds, but also the angular positions of the individual cams that match each other can be achieved. The machining program is thus determined by the different shape or offset mounting of the individual cams.
  • the drive motors for the slides can also, if necessary additionally, be program-controlled, ie run according to preferably electronically stored individual programs. In this case, crank drives are expediently used instead of cam disks for moving the slides.
  • the shaft of the motor or an associated gear and the cam or crank are arranged with an axis running perpendicular to the base plate and are in drive connection by means of spur gears or chains and chain wheels embedded in the base plate.
  • the spatially free arrangement of the carriage assemblies is preferably accomplished in that the carriage assemblies are mounted on a base plate which is preferably provided on both sides with the aid of clamping brackets.
  • the clamping brackets can include angles, inclined trestles, bridge-shaped construction elements or the like. be provided with plenty of screw holes or slots to be connected on the one hand to the boards of the carriage units and on the other hand with sliding blocks that can be moved in the T-slots of the base plate. In any case, the intention is to use these clamping brackets in many ways.
  • the base plate is advantageously arranged slightly inclined to the vertical, as a result of which the machining zone of the bending tools is best accessible.
  • the base plate which is preferably equipped with a central window, forms the essential supporting element of a stamping and bending device which works with slide units as described above.
  • pull-in, punching and additional devices can be attached to the base plate on the side, front or rear.
  • a flat base plate instead of a flat base plate, however, it is also possible to provide a curved clamping plate or any spatial clamping frame for attaching the slide units.
  • the machine or device can be designed as a modular system. Only as many slide assemblies are required as the bent part to be manufactured requires.
  • the basic structure of the device namely essentially the base plate or other supporting structure, which does not include a drive and no moving parts, is relatively simple and inexpensive. Over the course of time, additional slide units can then be purchased in accordance with the production planning.
  • the device is also extremely suitable for particularly large or bulky bent parts due to its extraordinary adaptability.
  • Figures 1 and 2 show a parallel-surface base plate 1, which is provided on both sides with parallel T-grooves 2, as are common in machine tool construction.
  • the base plate 2 is inclined to the rear by an angle of approximately 15 ° with respect to the vertical and is fixedly arranged by means of a base frame 3. It has a rectangular window 4 in the middle.
  • the base plate can be enlarged on the right or left by further fastening surfaces 5, which are indicated by dash-dotted lines. A feed station, punching devices, etc. can be attached to this.
  • the mounting bracket 6 has the shape of a desk and the mounting bracket 7 is angular. Both are screwed to the base plate 1 and also connected to the attached slide units by screws.
  • the housing 11 of a multi-part bending tool with which the various slide units interact.
  • the individual carriages carry punching, bending or mounting tools and FIG. 1 shows that they can take any direction of movement.
  • the carriage assembly 9 is arranged so that the stroke direction meets the tool housing 11 at an incline from the front, while the carriage assembly 10 is arranged on the back and its direction of movement runs through the window 4 perpendicular to the base plate.
  • Two further carriage assemblies 12 are attached directly to the front plate on the base plate 1, also with different directions. Further carriage units 13 and 14 in another different orientation are indicated by dash-dotted lines. They require corresponding clamping brackets, not shown.
  • the individual carriage assembly shown in FIGS. 3 and 4 is built on a circuit board 15, the essentially rectangular base area of which tapers on one side and has two fastening slots 16.
  • a slide 18 is slidably mounted in two parallel guides 17, which has a downward extension 19 and an upward extension 20.
  • the carriage 18 On the surface, the carriage 18 has cross-shaped grooves and threaded holes for attaching the associated bending finger 21, which is indicated by dash-dotted lines.
  • the projection 20 carries a feeler roller 23 which can be adjusted in the direction of movement of the slide by means of screws and which bears against a cam disk 24.
  • the cam 24 is mounted so that its axis extends perpendicular to the circuit board 15 and at the lower end of the cam shaft a drive gear 26 is seated, which is embedded in a correspondingly large recess on the underside of the circuit board 15.
  • a servo motor 27 is mounted behind the cam disc in such a way that its drive gear 28 is also received by the depression on the underside of the circuit board 15 and meshes with the drive gear 26. The depression can be replaced by a Bottom of the board 15 flush cover to be completed.
  • a servo motor 29 could be installed via an angular gear 30. Both are indicated by dash-dotted lines. The output shaft of the angular gear would drive the gear 28 in this case.
  • an electrical control device When operating several slide units with individual drives by servomotors within one device, an electrical control device ensures that the cams of all slide units are driven in the same direction.
