Definitions

  • the invention describes a device for simultaneous deburring and / or surface machining of the top and bottom of workpieces.
  • burr With every machining process, plastic deformation on the edges of the workpiece creates a burr that is generally undesirable because the function of the product can be impaired. The formation of burrs is minimized by constructional measures, but rarely completely avoidable. Deburring is a surface treatment method that removes the burrs created in the previous machining process.
  • the workpieces to be deburred have predominantly plane-parallel planar surfaces and have at these surfaces the ridge, which is efficiently removed by the machining process of the device and the affected edges are rounded.
  • plan brushing For flat surfaces in this case usually the plan brushing would be used.
  • Existing plan brushing processes in industrial production are carried out in a continuous process.
  • the parts to be brushed are magnetically or mechanically fixed on a belt or turntable and go through the brushing process.
  • the parts are first processed from one side. Then they are turned either manually or with an automatic, so that the other side can be edited.
  • the aim of the invention is to reduce the throughput times of the Bürstentgratens by the same time the top and bottom of the workpieces are processed.
  • the process of parallel and two-sided deburring of workpieces works analogously to surface grinding with planetary drive.
  • the invention relates to a device for simultaneous deburring and / or surface machining of the top and bottom of workpieces, wherein the workpieces are positioned between two horizontal superimposed brush discs in externally toothed workpiece holder.
  • the workpieces are manually fixed in the interventions of the workpiece holder on the lower brush disk, so that they loose in the Interventions are durable.
  • the upper brush disk is shut down to an adjustable fixed stop or a measuring system on the workpieces, so that the device closes.
  • the workpiece holders which are placed between an inner and an outer pin collar, are offset by a planetary drive in the region of the inner pin ring in relative movement to the likewise rotating brushes, whereby they rotate.
  • the number of workpiece holders depends on the size of the pin rings and the distance of the inner and outer pin ring each other. Depending on the diameter of the pin rings, a higher number of workpiece holders can be inserted between the two rings.
  • the interventions in the workpiece holders for the fixation of the workpieces can be designed individually.
  • the diameter of the engagement is the diameter of the workpiece to be machined, the depth of the engagement depends on the height of the workpiece.
  • Each of the two brush discs consists of a metal carrier disc and a Pertinax, plastic or aluminum brush holder mounted underneath or above, which is equipped with brushes over its entire surface.
  • the upper and lower brush disk and the planetary drive can vary both in the direction of rotation and in rotational speed. They can be rotated either clockwise or counterclockwise. The rotation speed can be freely set for all and adapted to optimize the deburring.
  • the upper and lower brush disks run in different directions at different rotational speeds and, in turn, for the planetary drive to drive the workpiece holders at a third speed.
  • the depth of penetration of the brushes is by lowering the upper brush disc on an adjustable fixed stop or by a Adjustable measuring system and can thereby be adapted to the respective height of the workpiece.
  • the processing of the workpieces in the device is controlled by the adjustment parameters penetration depth of the brushes on the top and bottom of the workpieces, the duration of processing and the speed of rotation of the brushes.
  • the combination of the setting parameters is based on the individual design and setting of the workpieces and enables targeted deburring and edge rounding of the workpieces to be machined.
  • the EP 1 629 941 A2 describes a device for deburring and / or surface improvements of machined workpieces, which has at least one brushing tool, through which a deburring and / or a surface improvement of the or the machined workpieces is feasible.
  • the device has at least two brushing tools lying opposite one another, that a transport device with at least one workpiece holder is provided, through which at least one workpiece can be moved between the brushing tools.
  • the invention differs from the just mentioned EP 1 629 941 A2 ,
  • the EP 1 629 941 A2 it is a device whose workpiece holders are manually or automatically equipped with workpieces, then the assembled workpiece holder is moved under the two opposing brushing tools, the workpiece holders are driven by means of the drive means, but only the inserted workpieces of the workpiece holder are deburred or surface improved , which is in operative engagement with the brush tools.
  • the workpiece holders which are not in operative engagement with the brush tools, may be further populated.
  • the workpieces were moved through the device.
  • the invention describes a device in which the workpieces are placed in the workpiece holder on the lower brushing disk, the device then closes by the upper Bürstscale herunteron and then the workpieces by the rotation of both the lower and the upper brush disk and the Workpiece holders on top and bottom are deburred and / or surface-treated. After the machining process, the upper brush disk moves upwards and the finished deburred and / or surface machined workpieces can be removed from the device.
  • the DE 10 2008 063 228 A1 describes a device for reciprocal grinding flat workpieces with an upper and a lower working disk, each having a work surface with an abrasive coating, wherein the work surfaces between them form a working gap in which workpieces can be ground, wherein at least one of the working disks by means of a drive is rotatably driven, and further comprising means for guiding the workpieces in the working gap.
  • deburring means which are designed to deburr the workpieces during their processing in the device, are arranged on at least one of the working disks.
  • the at least one working disk has at least one shaped receptacle, for example in the form of a groove, in which the deburring means are arranged.
  • the deburring means are arranged circumferentially in the work surface and / or extending radially in the work surface extending and / or extending arcuately in the work surface.
  • both brush discs consist of a carrier disc made of metal and one below (upper brush disc) or above (lower brush disc) mounted brush mount made of Pertinax, plastic or aluminum.
  • the brush holder of the lower brush disk and the brush holder of the upper brush disk are fully equipped with brushes.
  • Full surface in this context means that each of the entire surface or side that comes into contact with the workpieces, is equipped with brushes (see also FIG. 3 ).
  • FIG. 1 shows a plan view of the lower part of the device (1), consisting of the lower brushing disc (5) and the positioned thereon inner (2) and outer (3) pin collar.
  • the planetary drive (4) rotates the workpiece holders (WH1 - WH5) placed between the two pin rings (2, 3), the number depends on the size of the workpieces.
  • a workpiece holder has interventions (E1 - E5) into which the workpieces (W1 - W5) to be deburred and / or surface - treated are placed.
  • FIG. 2 shows a cross section of the device (1). Between the lower (5) and upper (6) brush discs are on the one hand the inner (2) and the outer (3) pin collar, on the other hand, the workpiece holder (WH1 - WH5).
  • FIG. 3 shows a cross section of the upper brushing disc (6) of the device (1), consisting of a carrier disc made of metal (7) and mounted under this carrier disc brush holder made of Pertinax, plastic or aluminum (8), which is fully equipped with brushes (9) ,
