Abstract
The invention concerns an anti-splinter device for sawing machines with a saw blade, the device being designed to be laid on workpieces on one side of the saw blade and to press against the saw blade near the point at which the saw-blade teeth emerge from the workpiece. The sawing machine has a positioning device which is connected to it and holds the anti-splinter device, and which positions the anti-splinter device in the correct operational position when the depth of cut and/or angle of inclination of the saw blade changes.
Description
The present invention relates to be used for the anti-device that isolates of saw blade formula electric saw, this device can be placed on the workpiece and can be contained in the saw blade side and contact with saw blade pressure at the position that the tooth of saw blade comes up from workpiece.
The metal laminate width of cloth is being cut in the machine of other plate of branch, in the machine of being addressed as BP 259716, it is relative with the position of saw blade constant that employing anti-isolated device.The result who does so particularly when depth of cut changes, has guaranteed anti-ly to isolate device and saw blade does not have influencing each other on function.Yet the side cut of material is irregular, must carry out refinish.
Based on above-mentioned skill, the objective of the invention is to this situation is improved.
According to the present invention, above-mentioned purpose can reach like this, a kind of anti-device that isolates that is used for saw blade formula electric saw promptly is provided, this device can be placed on the workpiece and can be contained in the saw blade side and contact with saw blade pressure at the position that the tooth of saw blade comes up from workpiece, wherein, should anti-isolate device and have a positioner at least, even this positioner can be connected and support the anti-device that isolates with so that anti-cutting splits device changes and/or saw blade inclination angle when changing in depth of cut with electric saw, still can place correct operating position.
The present invention in force, prevent isolating device always as such parts, these parts are in the operating condition of manual annular saw, actively engage the tooth that workpiece and saw blade expose simultaneously, so that prevent isolating device not only to workpiece, also apply power, and cooperatively interact with guaranteeing anti-positioner when isolating device and placing correct operating position to saw blade.Isolate the power that device applies and prevented to form the space between the device by anti-the tooth and anti-the isolating of saw blade.Isolate the cutting part that device is closely against workpiece in view of anti-, be not regarded as causing the space of the reason of cutting edge of breaking so also can not form at this position.Because the vibration of saw blade is suppressed, even is eliminated, so that line of cut is also become is more accurate.
Purpose of the present invention also can realize by following other measure:
The anti-device that isolates can be done radially to adjust with respect to saw blade, thereby can set it.
Anti-isolate the pressure that device acts on the saw blade and can be set.
Prevent that isolating device has a sensing part that contacts with the bar body pressure of saw blade, this pressure sensing spare supporting contacts with the tooth pressure power of saw blade and conduct prevents isolating the parts that parts design.
This sensing part and anti-to isolate parts be adjustable on the axis direction of saw blade.
Prevent that isolating parts can adjust with respect to sensing part, this sensing part is designed to as the stopping device of preventing isolating parts.
This sensing part is made of bearing material, prevents that isolating device then is made of the hardness material lower than the hardness of the tooth of saw blade.
Should anti-isolate device and comprise that a plug, this plug can be detachably connected on the electric saw and have two anti-parts that isolate, this two anti-ly isolates the both sides that parts can be contained in saw blade, and can contact with saw blade pressure.
The described anti-parts that isolate are connected on the plug part with movable joint.
Described anti-parts and at least one spring part of isolating cooperatively interacts to make and describedly prevents that isolating parts contacts with saw blade pressure.
Describedly anti-isolate parts and sensing part is housed at the position that contacts with saw blade.
But the described anti-parts that isolate are progressively parts of skew of manufacturing with cutting material.
Prevent that isolating device can be engaged in electric saw in the mode of movable joint, and the axis of flexible saw bar, perhaps the axis that extends around paralleling to the axis pivots.
This positioner has the shape of arm, and this arm can pivot around the axle that the axle that is parallel to saw blade extends, or can be positioned at one along one and adjust perpendicular to the camber line on the plane of this shaft extension exhibition.
Should anti-isolate device is the cylinder section shape, can rotate around its axle, but and be made of cutting material.
The axle of the pivotal axis of this arm and saw blade separates certain distance, and the radius that this distance and this cylinder prevent isolating device is identical.
The axle of this arm is set in directly over the axle of saw blade, and it defines an extension plane perpendicular to surface of the work with axle.
Should anti-isolate device cylindrical shape recess towards the saw blade opening was arranged.
Tilt to saw blade to the outside in anti-footpath of isolating device.
If what proposed anti-ly isolates the electric saw that device is used to have buck, the anti-parts that isolate device that then abut against workpiece are on the contact plane that is limited by workpiece and buck, and it is comparatively suitable perhaps to stretch out from buck towards workpiece.When electric saw was used for cutting coarse workpiece, this alternative method was particularly suitable.
Another suitable embodiment is to prevent that isolating device is adjustable with respect to saw blade, thereby can set it.According to the present invention, if manually annular saw is the immersion saw, its submergence changes on request, then makes advantageous particularly in this way.Anti-radially adjustability of isolating device has guaranteed no matter when it always carries out pressure with the tooth of saw blade at least and contact.
Another embodiment of the present invention imagination is, anti-ly isolate the mode that device can movable joint engages and engage, and the axle of flexible saw bar with electric saw, perhaps around with this pivot that extends in parallel.This measure can guarantee, even when the submergence of saw blade changes in cutting operation, anti-ly isolates device and also can engage effectively with the tooth of saw blade.Another imagination is, anti-ly isolates device with at least one spring part cooperatively interacts, and by means of this, preventing isolating the pressure that device acts on the saw blade can be determined.Adopting this measure, mainly is to consider the saw blade that can use different size like this in electric saw.
Another specially suitable embodiment imagination is, the anti-device that isolates has one and contacts and supporting the sensing part that contacts and be designed to prevent isolate the parts of parts with saw blade tooth pressure power with saw blade bar body pressure.Sensing part so reduced the wearing and tearing of the parts that contacts with the tooth pressure power of saw blade widely, because will have been passed to saw blade and applied minimum pressure with anti-parts that isolate that the tooth of saw blade actively contacts to saw blade by the anti-actual pressure that isolates the device generation.Preferably the sensing part that is made of bearing material has been done two advantages so simultaneously as the shock absorber of saw blade, and the one, greatly reduce anti-wearing and tearing of isolating device, the 2nd, the anti-parts that isolate can be used than sensing part much soft that material constitutes.
Another specially suitable embodiment of the present invention is that imagination will be prevented isolating device and is put in the outer cover that can be detachably connected on the electric saw, like this, if anti-ly isolated certain parts abrasion of device, just can easily change.
An imagination is again, and positioner adopts arm shape, and it can pivot around the axle that the axle that is parallel to electric saw extends, and it is adjustable perhaps to follow the camber line that is positioned on the plane that stretches vertical with this.In this kind structure, can also get following mode, promptly prevent isolating device and adopt cylindrical section shape, but can constitute around its rotation and by cutting material.From notion of the present invention, if the radius that the axle of the pivot of arm and saw blade 14 is spaced apart and this distance prevents isolating device with cylindrical shape is consistent then useful especially.
The axle of this arm is set in directly over the axle of saw blade, and it defines an extension plane perpendicular to surface of the work with the saw blade axle, thereby has guaranteed anti-ly to isolate tooth that device always is arranged in saw blade from position that workpiece comes up.The anti-device that isolates has the superiority towards the cylindrical shape recess of saw blade opening to be that anti-wearing and tearing of isolating the working face of device are uniform.At last, the anti-radially appearance of isolating device that tilts towards saw blade precautionary measures have been taked.Consequently, even under the situation surperficial in an acute angle of saw blade and workpiece, still can guarantee the anti-correct contact in device maneuverability ground of isolating.

Figure 18 shows the electric saw that has a pivotable buck and a positioner.
Fig. 1 shows and has saw blade 10 and the anti-electric saw that isolates device 16.The anti-device 16 that isolates can engage with the electric saw operation, can be resisted against the side blade tooth 14 that also can be placed in saw blade 10 on the workpiece (not shown) from position that workpiece comes up.In the buck 20 of electric saw, be formed with a saw blade passage 18, the saw blade 10 that rotates around axle 24 is installed in this passage.The anti-device 16 that isolates is designed to and can contacts as pressure with the tooth 14 of exposing of saw blade.In addition, the anti-device 16 that isolates can also design like this, and promptly it can be on the contact-making surface that is limited by workpiece and buck 20 against the position on the workpiece 34, perhaps stretches to workpiece from buck 20.Prevent that isolating device 16 places outer cover 50, its radial position is then limited by screw 36 and 38.Owing between limit screw 36,38 and outer cover 50, be not positive engagement, so be provided with the spring part 44 that presses to outer cover 50.
The anti-device 16 that isolates also has a sensing part 32 that contact with saw blade bar body 30 pressure and contacts with tooth 14 pressure of saw blade with one, and conduct prevents isolating the parts 34 that parts design.Sensing part 32 and anti-to isolate parts 34 be adjustable on the axis direction of saw blade 24, thus can set it.Prevent that isolating parts 34 can adjust with respect to sensing part 32, this sensing part 32 is designed as the stopping device of preventing isolating parts 34.In initial position, just before preventing isolating the device operation, be formed with a space 3 between the parts 34 at sensing part 32 and anti-isolating.If electric saw start this moment, so, but 14 in the tooth of saw blade actively engage with the anti-parts 34 that isolate that constitute with cutting material, thereby make gap 31 become minimum.At this position, anti-system is split parts carry on sensing part 32.In practice, when the sensing part 32 that contacts at the planar section pressure with saw blade bar body 30 is worn, anti-ly isolates parts 34 and can be subjected to further wearing and tearing.Though sensing part 32 isolates parts 34 and contact with 28 pressure with spring part 26 respectively with anti-,, spring part 28 only is to prevent that isolate parts 34 is pressed against sensing part 32.In addition, sensing part 32 and anti-ly isolate parts 34 and can give adjustment with adjustment screw 40 and 42, this kind adjustment is carried out at axle 24.Fig. 2 shows the two sides of saw blade 10, and each face and prevents that isolating device cooperatively interacts.In this configuration, anti-each parts that isolate device are close to the mirror image design.Sensing part 32 ', anti-to isolate parts 34 ' and spring part 26 ' corresponding approx with another corresponding component of preventing isolating device.
Fig. 3 to 5 shows can be around the anti-device 316 that isolates of axle 25 pivots through a hinge bar 48 and an articulated joint 46.Axle 25 is parallel with the axle 24 of saw blade 10.Like this, preventing isolating device 316 just can pivot with the direction of rotation of saw blade 10.Sensing part 32 isolates parts 34 and is placed in the outer cover 50 with anti-.Just as shown in Figure 4 and Figure 5, anti-ly isolate parts 34 further forward and the stop surface 52 of an inclination arranged.Articulated jib 48 cooperatively interacts and will prevent that isolating device 316 is pressed against workpiece with compression spring 54.
Fig. 6 and Fig. 7 show and have an anti-manual annular saw that isolates device 616, and this prevents that isolating device places protecting box 650, have a sensing part 632 and the anti-parts 634 that isolate.Contact and support sensing part 632 with spring part 626 pressure and prevent that the pillar 601 that isolates parts 634 also places outer cover 650.The anti-parts 634 that isolate can the movable joint mode rotate also and can pivot around axle 51 with respect to pillar 601, and sensing part 632 then available adjustment spiral shell to 40 is set.The anti-parts 634 that isolate can rotate also around the longitudinal axis of articulated jib 47 and can pivot on direction shown in the arrow.An articulated jib 47 and a spring part 49 cooperatively interact and will prevent that isolating parts 634 is pressed against workpiece 12.
Fig. 8 shows a buck 20 with a saw blade passage 18 and a protecting box 50.Have sensing part 32 and the anti-anti-device 16 that isolates that isolates parts 34 can be placed in the protecting box 50, only earlier these two parts placed another protecting box 2, like this, will prevent isolating device insert protecting box 50 and/or from this protecting box, take out does not all have difficult.
Fig. 9 and Figure 10 illustrate and prevent that isolating device also can be used for keyhole saw, and saw blade 914 is done vertically to reciprocating motion.
Figure 11 to 13 illustrates the anti-device 1116 that isolates that also therefore is designed to an individual components as the auxiliary of manual annular saw and keyhole saw.This kind prevents that isolating device 1116 comprises a plug 1118, this plug has two anti-parts 1120 and 1122 of isolating that can place saw blade 10 both sides respectively, isolate parts with the cutting material formation but these two anti-, that is to say it is that the material of hardness by hardness is lower than the tooth of electric saw constitutes. Anti-isolate parts 1120 and 1122,, have hardness greater than preventing isolating parts 1120 and 1122 and the best sensing part 1132 and 1134 that constitutes by bearing material at its and the position that saw blade 10 contacts.
Anti-another characteristic of isolating parts 1120 and 1122 is that they 1124 engage in the movable joint mode with plug 1118 with 1126 places in the position.Anti-parts 1120 and 1122 ends away from sensing part 1132 and 1134 of isolating cooperatively interact with compression spring 1130 sensing part 1132,1134 are pressed against saw blade 10.Articulated characteristic in succession specifically is based on such fact, owing to anti-isolating a space 1110 is arranged between parts 1120 and 1122; So prevent that isolating parts can contact with saw blade 10 pressure with being independent of each other by oneself for two.Like this, in fact they are that variable pressure contacts with saw blade 10, so can follow the lateral movement of saw blade 10.Electric saw has a socket 1136 with a strain screw 1140, in order to Fixing plug spare 1118.Anti-another characteristic of isolating device 1116 is, because its thickness is similar to consistent with the thickness of guide rail, so it preferably also can actively engage with the guide rail of electric saw, so that prevent that isolating device 1116 can closely offset with workpiece, and can not form the space that may play a major role between the parts 1120,1122 to the formation of the sliver on the edge regions of workpiece upper end at sawtooth 14 and anti-isolating.
Figure 14 to 16 shows the anti-parts 634 that isolate of cylindrical shape that supported by a positioner 3 with an arm 7.Arm 7 has two elbows, and directly over the axle 24 of saw blade 14, sentences articulated type in succession with the distance of axle 24 for r, and this is identical with the radius r of preventing isolating parts 634 apart from r.This has just guaranteed anti-ly to isolate tooth that parts 634 always can accurately be pressed against saw blade 14 on the workpiece 12 from position that workpiece 12 comes up.When arm 7 pivoted, the anti-supporting-point that isolates parts 634 moved along the endless track on the circumference of saw blade 14, and so, preventing isolating parts 634 can roll extrusion on workpiece 12.The anti-parts 634 that isolate have the cylindrical recess 5 of an opening facing to saw blade 14, and its circumferential surface 6 favours saw blade 14 (referring to Figure 16 and 17).Because the method, but isolate parts by cutting material anti-, as plastics constitute situation under, then the saw blade tooth may cause uniform wear to it.For minimum is reduced in the wearing and tearing of parts 634, in this illustrative embodiment, also be provided with a sensing part 32 that constitutes by the bearing material of the good sliding properties of tool.This sensing part can be made of bronze, sintering metal or graphite.
Arm 7 cooperatively interacts and will prevent that isolating parts 634 is pressed against workpiece 12 with tension spring 19.After even for a change depth of cut adjusts buck 20,, anti-ly isolate the appropriate point that parts 634 always can automatically be resisted against the tooth position of saw blade 14 perhaps in order to cut after bevelled edge or oblique angle cutting (seeing Figure 15 and 17) done to pivot.Figure 16 and 17 illustrates both sides all the anti-saw blade 14 that isolates parts 634.The anti-parts that isolate are by arm 7 supportings, and those arms be arranged in parallel, but independent separately.
But, as shown in figure 18 shown in the embodiment like that, anti-isolate parts 34 also can be designed to piece shape and with the positioner articulated type that is designed to bar 11 in succession, be installed in outer cover 8 or manually on the axle 13 on the guard shield of annular saw.Axle 13,15 and 24 runnings that are parallel to each other of each articulated joint.Obviously the face that tooth skimmed over than saw blade 14 is big on the anti-surface of isolating parts 34 that contacts with saw blade 14, preferably big at least about 4 times, therefore, in any depth of cut, that is to say each position at buck 20, sawtooth always keeps and prevents that isolating parts 34 contacts; Both made at buck 20 also like this when axle 9 pivots, described as the illustrative embodiment of front, anti-ly isolate the sensing part that no flank supported 32 that parts 34 are engaged in saw blade 14.For this purpose, sensing part 32 is contained in anti-being bordering on axle but apart from buck 20 end far away, perhaps being installed on the corresponding carriage of parts 34 of isolating.
Prevent that isolating parts 34 can move along its bearing-surface in the groove of buck 20, perhaps press to workpiece by the spring 54 ' that is supported on the protecting box 8, therefore, it is always straight.For example, bar 11 can be used to isolate parts 34 and be pressed against saw blade 14 anti-, and in this used, bar 11 was designed to have elasticity, and is contained in to make on the outer cover 8 to be applied with on the saw blade 14 and gives stress.Certainly, positioner 3 and 11 also is that the first from left right side disposes in couples and near saw blade 14, like this, saw blade all flexibly is subjected to an anti-effect of isolating parts in each side.
Positioner can certainly be done different designs.For example, particularly it is contemplated that out a kind of like this control cam, it is parallel to the saw blade extension and obtains guiding, an end bearing deflection protective device 34 of this arm along control arm.In this case, the size of control cam and arm should be: when buck was adjusted, the deflection protective device will be in its necessary position with respect to the sawtooth that comes up from workpiece.Another feasible embodiment propose to adopt one to have the hawser that gives stress, by dragline it, can set the deflection protective device.
What in general, propose anti-ly isolates device or the deflection protective device can be applied to Manual annular saw, keyhole saw, stationary saw, even other industrial electric saws. Because the anti-dress that isolates Put and to be assembled by the parts that separate, and then engage with manual annular saw, so its production Cost is very low. Owing to just prevented that at the sawtooth place material from breaking, do not need saw The platform parallel guide slots. Complete deflection protective device with sensing part on saw blade flexiblely Be guided, therefore, between sawtooth and deflection protective device, do not have the space to form. But, Sensing part also can adjust on demand.
Anti-another advantage of isolating device that proposes is that it can be installed in the lower of buck Face is even so the surface irregularity of workpiece also can prevent from isolating. Join at this kind In putting, to isolate that device flexiblely is attached on the electric saw be more favourable with anti-. Sensing part Isolate parts and be moulded parts with anti-, be easy to change, cost is low.
