Definitions

  • the invention relates to a cutting device for wood or other materials of any width according to the preamble of claim 1 and a saw blade clamping device.
  • Such a cutting device is used, inter alia, in commercially available multi-blade or edging circular saws.
  • the basic structure of these systems is described, for example, in the wood lexicon by E. König, DRW-Verlags-GmbH, Stuttgart, 1977, 2nd edition, Volume I: S.101-102 and Volume II: S.468-469.
  • These types of circular saws generally have two or more circular saw blades on a drive shaft, the distance between which can be varied. To ensure free cutting, the circular saw blades in the cutting area are usually made wider, for example by setting the saw blade. A resulting cutting width results from the distance between the side cutting edges of two adjacent circular saw blades. However, the resulting cutting widths can usually only be inadequately predicted simply by measuring the distance. Often after a rough presetting, a trial cut must be made, followed by a fine adjustment.
  • the cutting widths are set using a multi-blade saw sleeve, which is assembled outside of a machine and on which the individual saw blades are placed, spaced and tightened so that they cannot be adjusted any further.
  • the saw sleeve as a whole is replaced in order to keep the machine downtimes as short as possible.
  • the object of the present invention is to develop a device for cutting wood or other materials to any width, which provides a flexible, inexpensive adjustment which can be carried out within the machine and which can be securely locked in the sawing operation, the cutting widths being made by means of a suitable one Measuring system are controllable and adjustable.
  • the cutting device has disk-shaped carrier bodies which are axially displaceably mounted on the drive shaft and on which at least one circular saw blade is to be firmly mounted by means of suitable saw blade receptacles.
  • the circular saw blades are axially displaced by means of transport spindles which run parallel to the axis of the drive shaft and pass through the carrier bodies and move on a circular path around the axis of the drive shaft during the circular cutting movement of the circular saw blades.
  • the transport spindles Arranging the transport spindles around the axis of the drive shaft and mounting them in the disk-shaped, axially displaceable and rotationally fixedly connected support bodies results in a compact construction which, with a symmetrical arrangement of the transport spindles, on the smallest possible circular circumference, concentric to the axis of the drive shaft, ensures a smooth, balanced cutting movement with the lowest possible additional inertia forces.
  • the transport spindles which are preferably a thread, e.g. have a trapezoidal thread, the transmission of force and motion to the respective axially displaceable support body.
  • the carrier bodies are made much narrower, so that smaller minimum cutting widths and / or a larger number of mountable circular saw blades can be realized.
  • one circular saw blade is provided per axially displaceable carrier body.
  • the invention also includes variants in which a plurality of circular saw blades are to be fastened on a carrier body, which then have a fixed distance from one another and can only be axially displaced together.
  • At least one support body is axially fixed.
  • This carrier body is preferably located on the outside at the end of the transport spindles, the ends of which are freely rotatable and axially non-displaceable in it. This results in a more favorable distribution of the centrifugal forces occurring during the cutting movement.
  • a circular saw blade is preferably mounted on the axially fixed support body, from which the further cutting widths are fixed as a reference.
  • no circular saw blade is mounted on the fixed support body, so that all saw blades are axially displaceable.
  • the individual displaceable carrier bodies are each axially displaceable independently of one another. Only one carrier body is moved by means of each transport spindle, while the other carrier bodies remain unaffected by the activated transport spindle.
  • a carrier body is preferably axially displaced by two diametrically opposite transport spindles which are arranged at the same distance from the axis of the drive shaft.
  • the resulting bundle of transport spindles should preferably be arranged on a circumference concentric to the axis of the drive shaft. This arrangement enables a symmetrical distribution of the transport spindles at the same distance around the axis of the drive shaft.
  • the invention also includes variants in which more than two transport spindles are provided per axially displaceable carrier body.
  • the associated transport spindles perform a transport movement which serves for axial displacement, which preferably corresponds to a rotational movement about its own longitudinal axis and which can be synchronized between the two spindles by means of a gear.
  • the synchronized, counter-clockwise or synchronous transport movement of the transport spindles reduces the risk of the carrier bodies tipping and / or jamming on the drive shaft.
  • this transmission is designed as a belt transmission.
  • the invention also includes variants in which the coupling of the transport movement is implemented by means of other gears, for example gearwheels or chain gears.
  • the gearbox or gearboxes are arranged within a drive housing. This on the one hand achieves a compact design and on the other hand ensures that no contamination in the form of chips, for example, contaminates or blocks the individual gears during a machining process.
  • shoulder pins are provided, by means of which the respective transport spindles can be driven to implement their transport movement.
  • the transport movement is to be applied manually or by means of a suitable tool to the respective extension pin.
  • This tool can be, for example, a suitably shaped key that is to be placed on the respective shoulder pin and is to be operated manually, or a motor-operated screwdriver, the drive shaft of which is to be coupled in a rotationally fixed manner to the respective shoulder pin.
  • the invention also includes variants in which the transport movement of the transport spindles to be driven is applied centrally by means of the actual sawing machine, that is to say internally in the machine.
  • the shoulder pins are preferably formed from the extended ends of the transport spindles, so that the transport movement can be applied directly to a transport spindle in a simple manner.
  • a complete set of support bodies including the circular saw blades mounted on them, together with the associated transport spindles and the drive housing, can be assembled as a kit outside the machine room and, when changing tools, can be slid onto and attached to the drive shaft like a saw sleeve.
  • the attachment is preferably carried out axially by means of a lock nut.
  • the cutting device can be equipped like a multi-blade saw box and enables the cutting widths to be preset even outside the machine.
  • such a cutting device combines the advantages of a multi-blade saw box, such as quick tool set change, with small cutting widths and, moreover, enables the cutting widths to be adjusted without removing the device.
  • a saw blade clamping device for the radial and / or axial fixing of circular saw blades mounted axially displaceably on a drive shaft.
  • This saw blade clamping device has at least one clamping element which is mounted in the drive shaft like a piston and which can be moved radially by means of a hydraulically generated force.
  • the circular saw blades In a hydraulically unloaded starting position of the clamping elements, the circular saw blades can be moved axially on the drive shaft as before.
  • the clamping elements can be brought into an end position by hydraulically generated pressure forces, in which the circular saw blades are positively and / or non-positively connected to the drive shaft so that they can no longer be moved axially on the drive shaft.
  • the saw blade tensioning device has the advantage that a secure clamping of a variable number of circular saw blades is possible in any position. Neither saw bushes nor intermediate rings are required to establish a fixed distance between the individual circular saw blades that cannot be adjusted during sawing.
  • the saw blade clamping device ensures that the individual circular saw blades are immovably and securely locked on the drive shaft during sawing. continuous
  • the device can be used both in connection with a cutting device according to claim 1 and independently of it.
  • an additional axial securing of the positioned circular saw blades, relief of the transport spindles and blocking of a small axial mobility due to thread play can be achieved by means of the saw blade clamping device.
  • the circular saw blades can be moved axially immediately if necessary due to the quick and easy release lock and can then be locked again immediately.
  • a good sealing of the clamping elements with respect to the drive shaft means that there is no risk of contamination for the circular saw blades or the workpieces to be machined, e.g. hydraulic oil, on the other hand, the clamping device itself is not sensitive to contamination from sawdust or the like. A large part of the swarf is also kept away from the device by centrifugal forces during sawing.
  • the circular saw blades are preferably fixedly mounted on disk-shaped carrier bodies according to claim 1 or in a known manner on blade receiving rings provided therefor.
  • the circular saw blades are axially displaceably mounted on the drive shaft by means of the carrier body or the blade receiving rings. Since both the carrier body and the sheet receiving rings are known in comparison to the sliding heads ter, motor-adjustable multi-blade and edging circular saws can be made much narrower, smaller minimum cutting widths and / or a larger number of mountable circular saw blades can be realized.
  • the clamping elements correspond in shape and effect to a radially displaceable feather key, of which two are preferably provided, these being diametrically opposed on the drive shaft.
  • the invention also includes variants in which only one clamping element or in which more than two clamping elements are provided.
  • clamping elements can be provided which have a profile which, for example, in the locked state engages in a corresponding profile of the circular saw blades, the support body or the blade receiving rings, in order, for example, to produce an additional positive connection.
  • a maximum radial displacement of the tensioning elements is to be limited by stroke limiting elements, in particular by lifting screws. These are e.g. Appropriate so that the clamping elements do not fall out of their storage when no circular saw blades are attached to the drive shaft.
  • the hydraulic force is applied by means of a piston that can be moved manually or by motor.
  • the piston In the case of manual actuation, the piston is to be axially displaced, for example with a handle or a handwheel, by means of a threaded bolt which is screwed in or out of a thread.
  • the hydraulic force is to be applied by means of an internal or external hydraulic system. Since many machines already have an internal machine Hydraulic system have, a pressure build-up necessary for locking the circular saw blades or for the radial displacement of the clamping elements is also to be applied by means of such a system.
  • the saw blade tensioning device according to the invention is integrated into a hydraulic control and is therefore quick, easy and safe to use in a simple manner. The same also applies when the saw blade clamping device is connected to a hydraulic system external to the machine.
  • the saw blade tensioning device has a manometer by means of which the hydraulic force can be monitored.
  • a manometer on which the pressure at which the carrier bodies or the blade holder rings are tensioned enables a check to be made as to whether the circular saw blades are adequately locked in view of a safe machining process.
  • a measuring system for adjusting the cutting width is provided, in which the distance between the lateral cutting edges of two adjacent, relatively adjustable circular saw blades can be measured.
  • the measuring system preferably has a measuring plate with measuring surfaces, which is connected via a rotatable and extendable rod, which is arranged parallel to the axis of the drive shaft, to a position measuring system which is fixedly mounted relative to the drive shaft.

Abstract

L'invention concerne un dispositif de coupe destiné au bois et autres matériaux, comprenant un dispositif de serrage de lames de scie pour la fixation radiale et/ou axiale de lames de scie circulaire fixées sur un arbre d'entraînement et pouvant se déplacer axialement. Selon l'invention, des corps-supports (3) placés sur l'arbre d'entraînement (1) et pouvant se déplacer axialement sont respectivement destinés à au moins une lame de scie circulaire, p.ex. (2a). Le déplacement axial des lames de scie circulaire, p.ex. (2a), est assuré par des broches de transport, p.ex. (7), qui sont parallèles à l'axe de l'arbre d'entraînement et qui traversent les corps-supports, p.ex. (3). L'arbre d'entraînement (20) loge au moins un élément de serrage (21) qui est logé de manière à pouvoir se déplacer radialement. Lors de la première phase, les lames de scie circulaire, p.ex. (2a), portées par les corps-supports (3), sont déplacées par ledit élément de serrage (21). Lors de la deuxième phase, les lames de scie circulaire, p.ex. (2), ou les corps-supports, p.ex. (3), sont reliés par liaison de forme et/ou de force à l'arbre d'entraînement. Le dispositif de l'invention permet de régler la largeur de coupe sans un démontage coûteux en temps et en main d'oeuvre des lames de scie. Les corps-supports destinés aux scies circulaires sont plus étroits que les têtes de déplacement connues destinées aux scies circulaires à lames multiples. Cela permet de monter un plus grand nombre de lames de scie circulaire sur un axe.
