Definitions
- the invention relates to a splinter guard for sawing machines with a saw blade according to the preamble of claim 1.
- the splinter guard occupies an unchanged position with respect to the saw blade, which means that, especially when the depth of cut changes, no functional interaction between the splinter guard and the saw blade is guaranteed. As a result, the cutting edge of the material is not clean and must therefore be reworked.
- the object of the invention is to remedy this.
- the invention is implemented in any case if the splinter guard is a body which, when the hand-held circular saw is in operation, is at the same time operatively connected both to the workpiece and to the saw blade teeth which are moving out. so that the splinter guard does not only exert force on the workpiece, but also on the saw blade and works with a positioning device which ensures that the splinter guard assumes the operational position.
- the force exerted by the splinter guard prevents the formation of a gap between the saw blade teeth and the splinter guard. Since the splinter guard lies snugly on the workpiece in the area of the cut, there is no gap in this area, which is regarded as the cause of an unclean cutting edge. By suppressing or even eliminating vibrations of the saw blade, the cutting line is also much more precise.
- the proposed anti-splintering device is used in sawing machines with a saw table, then it is expedient if the part of the anti-splintering device lying on the workpiece lies in the contact plane defined by the workpiece and the saw table or protrudes from the saw table in the direction of the workpiece.
- the alternative proposal is particularly suitable if the sawing machine is used to cut uneven workpieces.
- splinter guard can be adjusted and adjusted in relation to the saw blade. This measure of the invention can be used particularly advantageously when the circular saw as. Diving saw is designed, the diving depth is changed as required. By the radial adjustment of the splinter guard ensures that the splinter guard is always at least in pressure connection with the saw blade teeth.
- the splinter guard can be connected in an articulated manner to the sawing machine and can be pivoted about the axis of the saw blade or about an axis running parallel to this axis. This measure ensures that the splinter guard can be operatively connected to the saw blade teeth even if the depth of the saw blade changes during the cutting process. It is further provided that the splinter guard works with at least one spring element, by means of which the pressure of the splinter guard acting on the saw blade can be determined. This measure takes into account above all the fact that saw blades with different dimensions can be used in a sawing machine.
- the chip protection has a sensor which is in pressure connection with the body of the saw blade and which carries the pressure connection with the saw blade teeth and is trained as a chip protection member.
- splinter guard can be accommodated in a housing which can be detachably connected to the sawing machine, so that the individual parts of the splinter guard are worn out and can be replaced without further ado.
- the positioning device has the shape of an arm which can be pivoted about an axis which runs parallel to the axis of the S blade or is adjustable along a curve which lies in a plane running perpendicular to the axis.
- the splinter guard has the shape of a cylinder section, can be rotated about its axis and consists of a material that can be cut.
- the pivot axis of the arm is at a distance from the axis of the S-blade 14 which corresponds to the radius of the z-shaped splinter guard.
- the features of claim 17 ensure that the splinter guard is always arranged in the area of the saw blade tooth moving out of the workpiece.
- the advantage of the measures according to claim 18 is that the splinter guard is evenly worn from its working side.
- the radial outside of the splinter guard drops towards the saw blade. This ensures that the splinter protector rests on the machine even when the saw blade defines a sharp angle l with the plane of the workpiece.
- FIG. 4 shows the machine shown in FIG. 3 in the direction of arrow IV, namely during the cutting process
- FIG. 10 the jigsaw shown in Fig. 9 in side view.
- Figure 13 the saw in the direction of Pfe. Shown in Fig. 12 'iles XII,
- FIG. 14 shows a part of a sawing machine in a side view with a positioning device designed as an arm
- FIG. 15 is a front view of the sawing machine shown in FIG. 14,
- Figures 16 and 17 a part of a sawing machine with two Positionierein ⁇ chtept and.
- ' 18 is a sawing machine with a swiveling saw table and a positioning device.
- FIG. 1 shows part of a sawing machine with a saw blade 10 and a splinter guard 16.
- the Spanre ßschutz 16 is operatively connectable to the sawing machine, can be placed on a workpiece, not shown, and can be ordered laterally from the saw blade 10 and in the area of the saw blade teeth 14 moving out of the workpiece.
- a saw blade passage 18 is formed, in which the saw blade 10 is rotatably mounted about the axis 24.
- the splinter guard 16 is designed such that it is in pressure connection with the saw blade teeth 14 extending out.
- the splinter guard 16 is also designed such that its part 34 which can be placed on the workpiece lies in the contact plane defined by the workpiece and the saw table 20 or protrudes from the saw table 20 in the direction of the workpiece.
- the Spanrei ßtik 16 is housed in the housing 15, the radial position of which can be determined by the screws 36 and 38. Since there is no rigid connection between the adjusting screws 36, 38 and the housing 50, spring elements 44 are provided which exert pressure on the housing 50.
- the splinter guard 16 also has a sensor 32 which is in pressure connection with the body 30 of the saw blade, and the part 34 which is in pressure connection with the saw blade teeth 14 and is designed as a chip guard member 34. It can be seen that the sensor 32 and the splinter guard 34 are adjustable in the axial direction of the saw blade 24 and are adjustable here.
- the Spanre ßstofforgan 34 is relatively adjustable with respect to the sensor 32, wherein the sensor 32 is designed as a driver of the Spanrei ßstofforgangs 34. In the starting position, that is to say before the anti-splintering device is put into operation, a gap 31 is formed between the sensor 32 and the anti-splitting device 34.
- the saw blade teeth 14 are operatively connected to the anti-splintering member 34, which can be cut from material, so that the gap 31 is minimized.
- the anti-splinter device is supported on the sensor 32. Further wear of the anti-splintering member 34 occurs practically when the sensor 32 is worn, which is in pressure connection with the flat section of the body 30.
- both the sensor 32 and the anti-splinter element 34 are in pressure connection with a spring element 26 or 28, the spring element 28 can only press the anti-splinter element 34 against the sensor 32.
- the sensor 32 and the anti-splinter element 34 can also be regulated by adjusting screws 40 and 42, in the direction of the axis 24. In FIG.
- FIGS. 3 to 5 show a splinter guard 316 which can be pivoted about an axis 25 via a joint rod 48 and a joint 46.
- the splinter guard 316 can thus be pivoted in the direction of rotation of the saw blade 10.
- the sensor 32 and the anti-splinter member 34 are housed in a housing 50.
- the anti-splinter device 34 is leading and has a run-on slope 52.
- the articulated arm 48 works together with a compression spring 54 which tends to press the anti-splinter device 316 against the workpiece.
- FIGS. 6 and 7 show a hand-held circular saw with a splinter guard 616, which is accommodated in a housing 650 and has a sensor 632 and a splinter guard organ 634.
- a body 601 is accommodated in the housing 650, which is in pressure connection with the spring element 626 and carries both the sensor 632 and the anti-splintering element 634.
- the sensor 632 can be adjusted by means of the adjusting screw 40, while the anti-splinter device 634 can be connected to the body 601 in an articulated manner and can be pivoted about the axis 51.
- the Spanrei ßstofforgang 634 is rotatable about the longitudinal axis of the articulated arm 47 and can be given away in the direction of the arrows.
- the articulated arm 47 works together with a spring element 49 which strives to press the anti-splinter device 634 against the workpiece 12.
- FIG. 8 shows a saw table 20 with a saw blade diameter 18 and a housing 50.
- the splinter guard -16 with the sensor 32 and the splinter guard member 34 can be inserted into the housing 50. 'These two parts are also housed in a further housing 2, so that the insertion or removal of the Splinter protection 16 in the housing 50 or from this can be done easily.
- a Spanre ßtik 1116 is shown, which is provided as an accessory for circular and jigsaws and is thus formed as a separate part.
- This anti-splintering device 1116 consists of a plug-in part 1116 with two anti-splitting devices 1120 and 1122 that can be positioned laterally from the saw blade 10, made of a material that can be cut, i.e. H. a material whose hardness is less than the teeth of the sawing machine.
- the anti-splinter elements 1120 and 1122 have 10 sensors 1132 and 1134 in the contact area with the saw blade, the hardness of which is greater than the hardness of the anti-splinter elements 1120 and 1122 and which preferably consist of bearing material.
- Spanrei ßstofforgange 1120 and 1122 are articulated to the plug 1118, in the areas 1124 and 1126.
- the ends of the anti-splintering devices 1120, 1122 facing away from the sensors 1132, 1134 work together with a compression spring 1130 which the aim is to press the sensors 1132, 1134 against the saw blade 10.
- the peculiarity of this articulation is in particular that the gap 1120, which is formed between the anti-splinter devices 1120, 1122, allows both anti-splinter devices to be brought into pressure connection with the saw blade 10 independently of one another. she are, so to speak, floating with the S blade 10 in pressure connection and can therefore follow lateral movements of the saw blade.
- the machine has a plug-in receptacle 1136 with a clamping screw 1140, which is used to fix the plug-in part 1118.
- Another peculiarity of the anti-splinter guard 1116 is that it can preferably also be operatively connected to guide rails for S machines, since its thickness corresponds approximately to the thickness of the guide rails, so that the chip guard 1116 can rest on the workpiece without that between the S tooth 14 and the chip guard 1120, 1122 would form a gap, which contributes decisively to the formation of splinters in the area of the upper edges of the workpiece.
- FIGS. 14 to 16 show a cylindrical anti-splinter device 634 which is supported by a positioning device 3 having an arm 7.
- the arm 7 is cranked twice and articulated at a distance r perpendicular above the axis 24 of the saw blade 14.
- the distance r corresponds to the radius r of the anti-splinter device 634. This ensures that the anti-splinter device 634 always rests on the workpiece 12 exactly where the teeth of the saw blade 14 move out of the workpiece.
- the contact point of the anti-splinter device 634 moves on a circular line along the circumference of the saw blade 14, whereby it can roll on the workpiece 12.
- the anti-splinter device 634 has a cylindrical recess 5 which is open towards the saw blade 14, and its peripheral surface 6 slopes away towards the saw blade 14 (cf. FIGS. 16, 17). With this measure, it can be achieved in a chip protection device made of a cutable material such as plastic that it is evenly worn by the saw blade teeth.
- a sensor 32 consisting of a bearing material with good sliding properties is also provided in this exemplary embodiment.
- the sensor can be made of bronze, sintered metal or carbon.
- the arm 7 works together with a tension spring 19 which presses the chipbreaker 634 against the workpiece 12.
- the anti-splinter device 634 automatically always comes to the right place in the area of the teeth of the saw blade 14 to lie. It can be seen from FIGS. 16 and 17 that the saw blade 14 is flanked on both sides by a splinter protection element 634, which are supported by arms 7 arranged in parallel but separated.
- the chip protection device 34 can also be block-shaped and articulated to a positioning device designed as a rod 11. This is pivotally arranged in the axis 13 on the housing 8 or on the protective hood of the circular saw.
- the axes 13, 15 and 24 of the joints run parallel to one another.
- the surface of the anti-splinter device 34 which bears against the saw blade 14 is clearly, preferably at least about four times, larger than the surface covered by the teeth of the saw blade 14, so that the teeth at every cutting depth, i.e. remain in contact with the anti-splinter device 34 at every position of the saw table 20; even if the saw table 20 is pivoted about the axis 9.
- the anti-splinter device 34 is connected to a sensor 32 which is supported on the toothless side surface of the saw blade 14.
- the sensor 32 is arranged at a point of the anti-splinter device 34 near the axis and remote from the saw table 20 or even on a corresponding arm.
- the anti-splinter device 34 can be displaceable in a groove of the saw table 20 along its support surface or is pressed onto the workpiece by means of a spring 54 'supported on the housing 8, so that it always lies flat.
- a spring 54 'supported on the housing 8 For pushing the anti-splintering member 34 against the saw blade 14 can be used, for example, the rod 11, which is then designed to be resilient and is mounted on the housing 8 with a prestress towards the saw blade 14.
- the positioning devices 3 and 11 are also arranged in pairs to the left and right of the saw blade 14, so that this is resiliently acted upon on both sides by a chip protection device 34.
- the positioning device could of course also be designed differently.
- a control curve would be conceivable, for example, which runs parallel to the S blade and is guided along a control arm, one end of which carries the pull-out protection 34.
- the control curve and the arm should be dimensioned so that the pull-out protection when adjusting the table takes the required position with respect to the saw blade teeth moving out of the workpiece.
- Another design option is a pre-tensioned cable, which sets the pull-out protection.
- the proposed chip protection or the pull-out protection system can be used in circular saws, jigsaws, stationary saws or large saws.
- the manufacturing costs of the Spanrei ßs protection are criminal because it can be made from separate parts, which are then operationally connected with a circular saw. Tearing out of the material is prevented directly at the saw tooth, so that no parallel guidance of the saw table is required.
- the complete pull-out protection with feeler is guided resiliently on the saw blade, so that there is no gap between the S teeth and pull-out protection.
- the sensor can also be readjusted as required.
- Another advantage of the proposed anti-splintering device is that it can also be attached below the saw table. This prevents chipping even when the workpiece surface is uneven. It is advantageous to attach the splinter guard to the S machine. Feeler and anti-splintering device are molded parts that can be exchanged easily and inexpensively.
