Definitions

  • the invention relates to a multi-sided planer according to the preamble of claim 1.
  • Multi-sided planing machines are planing machines with two or more tool shafts, the tools of which machine the workpiece as it passes through on different sides, at least on the top and bottom.
  • the simplest form is represented by thickness planers, which plan the workpiece to a constant thickness (planing thickness).
  • this machine In front of the first (lower) tool shaft, this machine has a height-adjustable front table.
  • the height difference of the front table to the top point of the tool flight circle determines the thickness of the lower chip to be cut. This thickness is fixed and cannot be changed during the run. Following the processing on the underside, the rest of the excess of. the upper tools planed on the top.
  • the invention has for its object to provide a generic - multi-sided planing machine in which a higher material yield is achieved by better distribution of the oversize on the upper and lower tools.
  • the multi-sided planer according to claim 2 represents a skilful constructive embodiment of the invention.
  • the feature of claim 3 ensures a smooth planing surface without a blow.
  • the workpiece can be pressed flat with an adjustable pressure, which enables planing with a smaller chip thickness.
  • the feature of claim 5 enables an exact feeding of the workpiece between the pressure plates.
  • the features of claim 6 ensure a large-area power transmission from the transport device even to warped workpieces.
  • the feature of claim 7 enables precise positive guidance of the workpiece to the tool.
  • Figure 1 shows roughly schematically a vertical longitudinal section through part of the multi-sided planer with the features according to the invention.
  • Figure 2 shows the control of the distance of the slide rails in the multi-sided planer according to claim 9.
  • the multi-sided planing machine has a solid machine frame 1 in a welded construction, in which a tool shaft 2 is mounted horizontally and transversely to the feed direction, which carries the planing tool 3.
  • the machine frame 1 ends behind the tool shaft 2 with a horizontal planing table 4, the planing table surface being aligned with the highest point of the flight circle of the tool 3. (- "In front” and “Behind” are always seen in the feed direction).
  • a superstructure 5 is supported in a height-adjustable manner, e.g. over columns and guides with synchronously running threaded spindles.
  • a second tool shaft 6 with tool 7 is mounted horizontally in the superstructure 5.
  • transport and pressure devices with the associated control devices, suction systems for the shavings etc. are accommodated, which are not the subject of the invention.
  • a two-part centering device is installed in the machine frame 1 and the superstructure 5, mirror-symmetrical to the central plane 8 between the two horizontal tangents of the flight circles of the tools 3, 7.
  • the centering device consists of a lower housing 9 and an upper housing 10, both of which are in parallel cranks 11, 12 and 13, 14, which are connected to each other with adjustable trailing arms 15 and 16, vertically movably mounted in the machine frame 1 and superstructure 5.
  • horizontal pressure plates 17, 18 lying one above the other are rigidly fastened and extend over the entire width of the planing machine and the pressure surfaces 17.1, 18.1 of which face one another.
  • the lower pressure surface 17.1 extends directly to the flight circle of the lower tool 3 and is aligned with the highest point of the flight circle in the starting position.
  • the printing area 18.1 coincides with the printing area 17.1. In the starting position it is aligned with the lowest point of the flight circle of the tool 7.
  • an equivalent coupling can also be used, for example rigid adjustable handlebars or a system consisting of racks and pinions.
  • a throttle valve (not shown) is installed in the return of the hydraulic housing coupling.
  • Pneumatic cylinders 22 two in the present example — act on the lower parallel crank 12, which determine the pressure force of the pressure plates 17, 18 and hold the housings 9, 10 in the starting position.
  • a shaft 23-26 is mounted transversely to the feed direction.
  • the shafts 24, 25 on the inlet side are provided with a plurality of deflection rollers 27 - in the present example there are 7 -, the shafts 23, 26 on the outlet side are driven and have the same number of chain wheels 28.
  • a coated roller chain 29 runs in each of the housings 9, 10 via a pair of sprocket deflection pulleys.
  • the distance between the inner runs 29.1 is increased from one another, which means that the passage opening in the inlet is widened for better loading.
  • the deflection rollers 27 are covered by parallel guide plates 30 in the inlet.
  • each slide rail 31 has the shape of a pressure shoe and is rotatably mounted at its rear end in the associated housing 9 or 10. In the central area, each slide rail 31 is supported by hydraulic cylinders 32. It is also possible to rotatably support the slide rails 31 at their front end and at the same time to support them in the middle or rear region.
  • the hydraulic cylinders 32 of two superimposed slide rails 31 are connected to one another via lines 33 (FIG. 2). The lines 33 are switched so that two superimposed slide rails 31 move essentially in the same direction, ie, they move in parallel.
  • a cylinder 34 with an adjustable air cushion is additionally switched on, which allows easy adaptation to irregularities in the workpiece top allows area. This adjustment is limited by an adjustable stop 35.
  • the drawn (outer) runs of the chains 29 are additionally tensioned by chain tensioners 36.
  • the centering device Before the workpiece runs in, the centering device is brought into the starting position: the planing thickness, i.e. the vertical distance between the flight circles of the tools 3, 7 from one another is set and the desired contact pressure of the pressure plates 17, 18 is built up via the pneumatic cylinders 22.
  • the planing thickness i.e. the vertical distance between the flight circles of the tools 3, 7 from one another is set and the desired contact pressure of the pressure plates 17, 18 is built up via the pneumatic cylinders 22.
  • the workpiece is inserted between the guide plates 30 in the multi-sided planer. It is then grasped by the pulling runs 29.1 of the transport chains 29 and continued. It pushes the slide rails 31 apart, as a result of which hydraulic oil is pressed from the cylinders 32 through the lines 33 into the cylinder 34.
  • This contact pressure can be set via the pressure of the air cushion in the cylinder 34. The warping of the workpiece is compensated for by dividing the transport surface into several parallel tracks - there are 7 in the example.
  • each slide rail 31 is supported by pneumatic cylinders instead of the hydraulic cylinders 32.
  • the pneumatic cylinders are connected to one another via a common air reservoir.
  • the same air pressure is thus present on all cylinders, and a uniform contact pressure of all transport chains 29 on the workpiece is ensured.
  • the contact pressure is set via the pressure of the air cushion in the common air reservoir.
  • the thickness of the chip planed from the lower tool 3 varies in the multi-sided planing machine according to the invention, since the excess of the workpiece is evenly distributed to the lower and upper tools 3, 7 during the passage.
