Definitions

  • the invention relates to a material feeding device for guiding strip material and wire in processing machines, in particular for machines for punching, bending and / or mounting, with a motor for transporting the material and a clamping device for fixing the material, wherein the motor for transporting the material as electric linear motor is formed
  • Such a sliding material feed direction for stamping and bending machines is described.
  • the movement of the material feeder is derived via a push rod and a material tongs from the main drive of the machine.
  • the material tongs convey the material to the machining position.
  • Such a feeding device is also referred to as a forceps feeder.
  • roller retractors are known in which the material is gekiemmt between two motor-driven rollers or rollers that feed the material.
  • the object of the invention is to provide a material feeding device for machines, in particular for punching, bending and / or assembling, with high cycle speeds available, which allows a further increase in productivity and beyond a precise and consistent over longer periods of material supply and Fixation allows.
  • the clamping device is arranged on the movable part of the linear motor, wherein the drive is formed in the clamping device as an electric linear motor, which preferably acts on a sliding gear on the clamping device, and a further clamping device is provided with the cooperates first clamping device and is connected to the fixed part of the linear motor for the material supply.
  • the main drive which moves the tools, can be done via the controller.
  • the stroke ie the increment of a power stroke, can be specified in a known manner by the controller or be defined mechanically as Endlagenanelle. Even combinations to increase the precision are conceivable.
  • the clamping device is arranged on the moving part of the linear motor, the precise movement is transferred to the material to be supplied.
  • the drive in the clamping device is designed as an electric linear motor, which preferably acts on the clamping device via a link mechanism, the respective operating state of the clamping device is advantageously also after switching off or failure Maintain the mains supply.
  • a further clamping device is provided, which cooperates with the first clamping device and is connected to the stationary part of the linear motor for the material supply, advantageously any missing holding forces of the tool on the supplied material are replaced.
  • the linear motor is designed as a synchronous motor, which allows a further increase in accuracy.
  • This purpose also serves the measure that the linear motor is designed controlled by a programmable servo control.
  • the material can be fed step by step to the tools with particularly high dynamics in a repeatable precision.
  • the accuracy is in the hundredth range or even better.
  • the servo controller can be equipped with a motor position absolute encoder, allowing the controller to accurately position control, resulting in a corresponding accuracy of finished parts.
  • an overlapping material guide is provided on the movable part of the linear motor.
  • the clamping device has a drive which is alternately designed to switch into the operating states of the clamping and release.
  • the drive of the clamping device is designed as a magnet.
  • the material to be supplied remains safely in the respective position when the machine is being used Magnet against the force of a spring, the clamping device is designed switching in the operating state of the release.
  • the clamping device has a spring-formed clamping surface, and thickness tolerances of the supplied material can be compensated.
  • the control advantageously has the effect that the clamping device is designed to work in cycles, wherein alternately one clamping device has the operating state of the release when the other clamping device is in the operating state of the clamping.
  • Fig. 1 denotes the tool of a processing machine 13.
  • the feeder 14 is drawn.
  • This consists essentially of the motor 1 which supplies the material and is fixedly mounted on the machine frame 15.
  • the motor 1 is designed as a linear electric motor 3, the stator 16 is fixedly connected to the machine frame 15 and the movable part 5 as the rotor Clamping device 4 carries.
  • the movable part 5 is guided laterally in linear guides 17 hanging.
  • Fig. 3 it can be seen that the machine frame 15 lying in a C-shape surrounds the linear motor, wherein the linear guides 17 are arranged to hold the movable part of the linear motor 5 under the free ends of the c-shaped machine frame hanging.
  • Fig. 2 The clamping device is shown enlarged in the side view.
  • the material 2 here a wire, is stretched between the commercial clamping jaw 18 and the material guide 6, wherein the clamping surface 8 is resilient. This suspension is achieved by the meandering design of the jaw, which clamps the material very secure despite their suspension.
  • the jaw is moved by a column 19, which is held vertically movable in a column guide 20.
  • the drive of the column via a further linear motor 9 which forms the drive for the clamping device together with the slide mechanism 10.
  • the fixed part 11 of the linear motor is fixedly connected to the movable part 5 of the linear motor 3.
  • the movable part is supported on the plate 23 and the linear guides 22 also on the movable part 5 of the linear motor 3, so that the entire clamping device moves with the movable part 5 of the linear motor 3.
  • a perpendicular to the plate arranged curve 24 is fixed, which is scanned by a deep groove ball bearing 25 as a backdrop.
  • the deep groove ball bearing 25 is rotatably mounted on an axle 26, which in turn is fixedly connected to the column 19.
  • the deep groove ball bearing 25 thus scans the curve 24, so that the column 19 with clamping jaw 18 also follows the curve.
  • a total of four clamping jaws are arranged below a common clamping bar holder 27, which is guided and moved by a total of two columns 19 in the manner described above. Due to the special design of the clamping device this is very stiff. In this way, it is also able to cope with the high dynamic loads of the feed device, which result from the high acceleration and braking forces of the linear motor 3 operated at high clock rate.
