Definitions

  • the invention relates to a saw chain for a tool for Separate sandwich panels, with side faces that at least partly from one behind the other in the direction of movement of the saw chain lying chain links are formed with cutting teeth, wherein the side faces of the saw chain face each other at a distance and facing the cut surfaces created during operation are and wherein cutting teeth between the side surfaces of the saw chain Cutting edges running transversely to their direction of movement have and with at least one tooth end face in one Side of the saw chain.
  • a guide is required to achieve good machining results the saw chain during the cutting process.
  • this object is achieved by a saw chain of the type mentioned at the beginning, in the case of which the characteristic Features of claim 1 are provided.
  • the sophisticated one Gradation of the side surfaces of the saw chain or the relevant one
  • the area or areas of the chain links mentioned can in particular be based on the chain link blanks commonly used with rectangular cross-section on production technology easiest way to create.
  • the side faces of the saw chain are graded when processing sandwich panels with only one Part, namely on the upstream subareas, in rubbing Contact with the created cut surfaces on the one to be machined Workpiece.
  • a small friction surface also requires one only small frictional resistance when moving the saw chain.
  • the composite construction of chain links described in claim 3 offers significant manufacturing advantages. So can be used to produce such links at least one blank part relatively large and at least a blank part of relatively small thickness about Welding to be connected together.
  • the invention There is a gradation of the side surfaces on the chain links then without further ado.
  • the composite construction of the chain links allows consideration the fact that different areas of the Chain links subjected to different stresses during operation are. For example in the area of the material to be processed Cutting teeth engaging sandwich plates act greater and different types of stress than in the other areas the chain links. With this in mind, the advantages are the type of the invention described in claim 4 Saw chain obviously.
  • the saw chain according to the invention is distinguished through a connection that can be produced with little effort Chain links among themselves.
  • the bolt heads of the chain bolts can be easily manufactured, for example as Create rivet heads. After being reset in the area Partial surfaces of the chain links or the side surfaces of the saw chain are arranged, with appropriate dimensions Bolt heads or at a suitable distance from the superior of the recessed partial areas of the chain links without further ado ensured that the bolt heads did not have the superior Protect part of the side surfaces of the saw chain and impair the saw chain guidance.
  • the spaces, those between those adjacent to each other in the direction of movement Outer members necessarily remain, by means of the middle members arranged at the level of the above-mentioned spaces the saw chain are closed.
  • the saw chain is dense Sequence of cutting teeth or cutting edges, where effective due to the characterizing claim feature Overall guidance of the saw chain with little manufacturing technology Effort is guaranteed.
  • the cutting tool 1 includes a cutting tool 1 for processing a sandwich plate 2 a base body 3 with a guide rail 4 for an endless saw chain 5.
  • the sandwich plate 2 consists of a foam core and neighboring on both sides Cover layers in the form of approximately 1 mm thick metal sheets.
  • the saw chain 5 is at the two ends of the guide rail 4th each deflected along an arcuate path and on the straight sides of the guide rail 4 guided in a straight line.
  • the saw chain 5 is driven by an electric motor 6 with two speed switching stages.
  • On its opposite the electric motor 6 Side is the base body 3 of the cutting tool 1 provided with a broken open in Fig. 1, which the saw chain 5 on the drive side, forming an intermediate space 8 encloses between saw chain 5 and housing 7.
  • In the gap 8 opens a suction hose 9, which has a Connection piece 10 of the housing 7 attached to the latter and connected at the other end to the suction side of a fan is.
  • a machine guide 11 of the cutting tool 1 essentially consists from a support plate 12 and a swivel bearing 13, by means of which the base body 3 of the cutting tool 1 around a parallel to the plate level of the sandwich plate 2 Axis 14 pivotally connected to the support plate 12 is.
  • a double arrow 15 illustrates the direction of the relative pivoting movement of base body 3 and support plate 12.
  • a slot 16 in the support plate 12 allows the base body 3 of the cutting tool 1 and with this the saw chain 5 between the working position according to FIG. 1 and a rest position, in which the saw chain 5 out of engagement with the Sandwich plate 2 is to swing back and forth.
  • this pivoting movement is available to the operator of the cutting tool 1 handles 17, 18 available on the base body 3.
  • a Locking device 19 This comprises a plurality of locking openings on the base body 3 of the cutting tool 1 and one in Lockable in the axial direction against spring force Locking pin 20, which is connected to a support plate 12 Bearing block 21 of the pivot bearing 13 in its axial direction is held displaceably.
  • the locking openings are located on the side of the base body facing away from the viewer of FIG. 1 3 and are in the direction of the pivoting movement of the base body 3 arranged in a row.
  • the operator of the separating device snaps opposite the support plate 12 1 the lockable locking pin 20 in one of the locking openings on.
  • the saw chain 5 from three lying next to each other transversely to their direction of movement 23 Rows of chain links 24, 25, 26. This is the chain links 24, 26 around each other constructively matching outer links, 25 ⁇ m for the chain links Center links of the saw chain 5.
  • the adjacent links 24, 26 are aligned with each other, while the middle limbs 25 in the direction of movement 23 of the saw chain 5 against the outer links 24, 26 are arranged offset and with in the direction of movement 23 of the saw chain 5 outer links one behind the other 24, 26 overlap (Fig. 2).
  • the sandwich plate 2 only act the superior Partial surfaces 31, 32 of the two rows of outer links 24, 26. There is a rubbing contact with the partial surfaces 31, 32 the respectively assigned cutting surface on the sandwich panel 2. After these friction surfaces are relatively small, however also occurring due to the lateral guidance of the saw chain 5 Frictional resistance for the movement of the saw chain 5 relative low.
  • the width corresponds of the strip-like projections 29, 30 and thus the width of the partial areas 31, 32 of the outer links 24, 26 approximately double the height of cutting teeth 35, 36.
  • the cutting teeth 35, 36 point transversely to the direction of movement 23 the saw chain 5 extending cutting edges 37, 38 and lie with their tooth faces facing outwards in the superior ones Partial surfaces 31, 32 of the outer links 24, 26.
  • Cutting teeth 39 of the center links 25 of the saw chain 5 have cutting edges 40, which is also transverse to the direction of movement 23 of the saw chain 5 run.
  • the outer links 24, 26 and the are connected to one another Center links 25 of the saw chain 5 with chain pins 41 each two bolt heads 42.
  • the bolt heads 42 are in the Area of the recessed partial surfaces 33, 34 on the outer links 24, 26 arranged and also opposite the superior Partial areas 31, 32 of the outer links 24, 26 are reset.
  • each chain pin 41 passes through two adjacent outer links 24, 26 and between this arranged center member 25 on a cross section stepped bore 46.
  • the chain pins 41 correspond to axial sections the gradation of the bores 46 radially expanded into a collar 43, the collar 43 slightly in the axial direction protrudes the outer surfaces of the respective center member 25.
  • the Outer links 24, 26 and the central links 25 of the saw chain 5 avoided. This in turn minimizes friction, which occurs when the outer links 24, 26 and the Center links 25 in the deflection of the saw chain 5 relative to each other pivot about the chain pin 41.
  • Deviating from the manufacturing process described above would initially also have tool steel strips with these reduced thickness iron sheet strips are welded can. A removal of material from the iron sheet Divide the chain link blanks obtained to produce the desired gradation on the outside of the chain links then unnecessary.
  • Blanks for the center links 25 were made from tool steel sheets each with a first attack surface 47 and one punched out second attack surface 48. Over the first attack surfaces 47, the central links 25 are in operation by one Sprocket driven, which in turn with the electric motor 6 of the cutting tool 1 according to FIG. 1 is connected to the drive. about the second contact surfaces 48 offset the central links 25 a guide sprocket at the free end of the also in Fig. 1 shown guide rail 4 in motion. As indicated in Fig. 3, run the first attack surfaces 47 and the second Attack surfaces 48 of the center members 25 each symmetrical with respect a perpendicular to the distance between the two holes 46 of the individual central links 25.
