Definitions

  • the invention relates to a device for grinding multi-blade knives with at least one motor and a relatively moving holding table according to the features of the preamble of claim 1.
  • a device for grinding multi-blade knives with at least one motor and a relatively moving holding table according to the features of the preamble of claim 1.
  • Such a device is made WO-A-99/39868 known.
  • the respectively clamped multi-blade blade is scanned by a fan laser before the actual grinding process, for example, to determine among other things, the exact grinding position.
  • a disadvantage of the known devices for grinding multi-blade knives is that the multi-blade knife between the first grinding on the first cutting and the second grinding on the second cutting relatively expensive must be readjusted, for example, to obtain a symmetrical grinding with respect to the grinding surfaces of the multi-blade blade.
  • a grinding machine for grinding cutting tools is in the patent application GB 2 061 781 A described.
  • This grinding machine is particularly suitable for grinding cutting tools of woodworking machines.
  • a motor axis of a motor is arranged transversely to a main displacement axis of a knife holding table.
  • the cutting edges of a cutting tool can additionally be ground with the head side of a rotating abrasive.
  • the adjustment of the cutting tools is quite complex with individual holders, which are fixed in each case by means of clamping screws.
  • the invention is based on the object to further develop such devices for grinding multi-blade knives.
  • the object of the invention is achieved by a device for grinding multi-blade knives with the features of claim 1.
  • the motor of the device serves primarily to drive a grinding tool, with which the cutting edges of the multi-blade knife are ground.
  • the multi-blade blade By means of the push rod tensioner, the multi-blade blade can be fixed on the holding table of the grinding device on the one hand, and the fixing by means of the push rod tensioner is particularly uncomplicated and can be released again. As a result, the risk of accidents is greatly reduced, whereby the work safety is substantially increased. In addition, different multi-blade knives can be clamped quickly and easily by means of the push rod clamp.
  • the motor axis, on which the grinding tool is arranged be set such that, for example, almost always an optimal grinding angle can be adjusted. Due to the transverse arrangement of the motor axis relative to the main displacement axis of the holding table, the holding table does not move as usual parallel to the motor axis, but rather at an angle thereto. This makes it possible, inter alia, to use other grinding tools than conventional grinding wheels for grinding the cutting edges.
  • the holding device is arranged on the holding table by means of a fixing device.
  • multi-blade knives are distinguished for use in a lawn mower between left and right runners.
  • the holding device is attached to the fixing device by means of a tensioning means.
  • the device has at least one further fixing device for a holding device.
  • a holding device is arranged to the right of the grinding tool so as to grind right-handed runners, and a further holding device to the left of the motor to grind preferably left-hand runners.
  • the holding device can then be arranged depending on the application either on the left or on the right fixing device. If, for example, a right-hand rotor is ground, it is delivered to the grinding tool from the right. If, in contrast, a left-hand rotor is ground, it is delivered to the grinding tool from the left.
  • the holding device is detachably arranged.
  • a holding device which is fixed to the first fixing device, for example, on the right fixing device to solve in a simple manner from this first fixing and attach to the other fixing device, for example, to the left fixing device.
  • the holding device can be fixed relative to the holding table.
  • the holding device comprises a hold-down device.
  • the multi-blade blade is fixed in a structurally simple manner in the point of symmetry of the multi-blade blade, for example on the holding table of the device.
  • the holding device thus described above makes it possible, among other things, to position, fix and change a position of the multi-blade blade or to change the complete multi-blade blade in a particularly simple and therefore time-saving manner.
  • the holding device can be fixed relative to the holding table.
  • the relative fixability of the holding device to the holding table is particularly advantageous in multi-blade knives, since according to the invention the positioning, in particular in a realignment of the multi-blade blade after grinding a first cutting edge before grinding a second blade of the knife is substantially simplified. Among other things, this results in a considerable reduction in the total machining time and in particular the set-up time with regard to a multi-blade blade.
  • main axis of displacement of the holding table is understood to mean essentially the one direction in which the holding table is mainly displaced during a grinding process.
  • a cup wheel is arranged on the motor axis.
  • the grinding cup which can now be used advantageously also in a device for grinding multi-blade knives due to the transverse position of the motor axis, in particular far more precise cuts on the cutting edges of the multi-blade knife can be made with respect to the angle.
  • the cup wheel comprises a material made of boron nitride
  • significantly less grinding dust is produced than in known devices for grinding multi-blade blades. This generally results in a much cleaner grinding process which, among other things, significantly improves the working conditions of an operator of the apparatus.
  • the holding table is movable relative to the cup so that when the motor stops the knife is no longer in contact with cup.
  • the holding table with the multi-blade knife clamped onto it can be moved manually, but also automatically, relative to the cup wheel.
  • the device comprises a further motor.
  • This motor is preferably used to receive a further grinding tool.
  • At least one motor is movable relative to the holding table. It is advantageous if the motor is movable vertically with respect to the holding table. The vertical mobility is used here, for example, to set the keyhole depth. But it is particularly advantageous if the motor is additionally or only exclusively horizontally movable relative to the holding table. With the horizontal movement of the motor, for example, a feed movement or a feed movement, which is otherwise performed by the movable holding table, can be realized.
  • the workpiece Due to the mobility of the motor not only as usual, the workpiece is movable relative to the tool, but also the tool to the workpiece. This relates in particular to a feed movement or feed movement during the actual grinding process.
  • a horizontal mobility of at least one motor relative to the holding table is also particularly advantageous if, for example, only one motor of two motors in the horizontal direction is movable.
  • the multi-blade blade is optimally delivered by means of the holding table on a first grinding cup of a first motor for a grinding process.
  • the second motor with its grinding head can advantageously be positioned optimally on the second cutting edge of the multi-blade blade. If the multi-blade knife is positioned in such a way to the two grinding heads of the two motors, the grinding process of both cutting edges of the multi-blade blade can be carried out in a grinding process.
  • a holding element is arranged on the holding table, which can be rotated by 180 ° in a holding table plane.
  • a holding element is advantageous, for example, to position the multi-blade blade faster and easier in the grinding device. If, for example, a first cutting edge of the multi-blade knife has been ground and then the second cutting edge of the multi-cutting knife is to be positioned for grinding in relation to the grinding tool, this process is simpler if the multi-cutting knife is arranged on a holding element.
  • the retaining element thus serves to receive the multi-blade blade.
  • the multi-blade blade is fixed on the support member before the support member itself is placed on the support table. This makes it possible to prepare a plurality of multi-blade blades to be ground, for example, for a faster grinding pass.
  • a multi-blade blade is arranged in each case on a holding element, wherein the holding elements comprising multi-blade knives are fed one after the other to the holding table.
  • the holding element can be fed to the holding table.
  • the device has a control panel, which is arranged in the lateral region of the grinding device.
  • lateral area is preferably understood to mean the area which is located along the main displacement axis of the holding table.
  • control panel in the lateral area is advantageous in that the actual grinding process can be much better viewed by the operator. This makes it much easier to make any corrections, for example, with regard to the grinding angle, the cutting depth or other process parameters.
  • control panel here preferably describes all components of the device, which are used for advantageous and simple operation of the device with respect to electrical and / or mechanical components of the device.
  • the device has a protective hood whose pivot axis in the direction of the main axis of displacement of the holding table is arranged. If the pivot axis of the guard in the direction of the main axis of displacement, the guard can be structurally very easy to design and operate.
  • the insertion, repositioning and removal of the multi-blade blade can be made much simpler than in an arrangement of the pivot axis transverse to the main direction of displacement of the holding table.
  • the device has a micro-spraying device for grinding cooling.
  • a micro-spraying device or a micro-cooling device has the great advantage over conventional cooling devices, which have hitherto been used in devices for grinding multi-blade knives, that the processing region or grinding region is not excessively contaminated with coolant.
  • the cooling device designed structurally particularly simple.
  • the coolant supply and spray particles can preferably be selected such that the entire supplied coolant evaporates. Thus, excessive contamination of the process space and in particular of the workpiece with spray or spray dust is reduced.
  • micro-spraying device is particularly advantageous in connection with the use of a cup made of boron nitride, since, as previously described, when using a cup made of boron nitrite only very little grinding dust accumulates, which can mix with the coolant.
  • the low-level grinding dust and the small amounts of coolant supplied by the micro-spraying device hardly contaminate the process space of the device, so that this in particular affects the cleaning and maintenance of the device according to the invention.

  • the two stops 21 and 22 are adjusted by the clamping means 14 and 16 with respect to the holding table 2 with respect to an optimal grinding position of the multi-blade blade 17.
  • the grinding table 2 is moved up along the two double arrows 23 and 24 to the cup wheel 7 of the motor 5.
  • the approach or delivery of the multi-blade blade 17 with respect to the sanding plate 7 happens here automatically.
  • the advancing movement of the holding table 2 in the left direction of the main displacement axis 24 takes place in this embodiment during the actual grinding process of the cutting edges 19 and 20 automatically.

If, for example, the cutting edge 19 has been finished, the multi-blade blade 17 is rotated by 180 ° in accordance with the arrows 33 and 34, so that in this way the cutting edge 20 is displaced in the immediate vicinity of the grinding head 7.
