Description

Technical Field

[0001] The invention relates to the technical field of cutting equipment, and in particular to an adaptive cutting device for aluminum alloy plates. Background Art

[0002] Sawing machine is a commonly used processing equipment, which uses replaceable and adjustable saw blades to cut aluminum alloy plates. Due to its high processing efficiency and low cost, it has been widely used in industrial production.

[0003] However, the existing sawing machine cutting technology is mainly suitable for cutting aluminum alloy plates with square or straight edges. In actual production, in addition to square cutting, there is also a demand for circular cutting of aluminum alloy plates. The circular part of the aluminum alloy plate cut out is the finished material part, and the remaining unnecessary part is the waste part. Since the saw blade has a certain width, it includes a saw blade part and a saw body part. Therefore, when using a sawing machine to perform circular cutting on aluminum alloy plates, due to the continuous change of the rotation direction of the aluminum alloy plate, the saw body part of the saw blade may interfere with the finished material part of the aluminum alloy plate, thereby causing the saw blade to deform and even produce cutting deviations. Summary of the invention

[0004] Based on this, it is necessary to provide an aluminum alloy sheet adaptive cutting device to address the problems existing in current sawing machines when cutting circles.

[0006] Further, the auxiliary saw frame comprises a C-shaped auxiliary mounting plate, an auxiliary inner baffle plate and an auxiliary outer baffle plate, wherein the auxiliary inner baffle plate and the auxiliary outer baffle plate are arranged on the side of the auxiliary mounting plate and form an auxiliary receiving groove for placing the auxiliary saw band wheel; An arc-shaped slide groove with the cutting position of the main saw blade as the center is opened on the processing table, a slider is arranged in the slide groove, a screw is installed on the slider, an adjustment connecting column threadedly connected to the screw is arranged on the secondary inner baffle plate, and the slider is slid in the slide groove through the adjustment connecting column to adjust the use position of the secondary saw blade assembly relative to the main saw blade.

[0007] Furthermore, the secondary saw blade assembly also includes a resettable baffle, which is arranged on a side of the secondary saw blade close to the main saw blade, and one end of the baffle is pressed against the side of the main saw blade to form a support between the main saw blade and the secondary saw blade.

[0008] Furthermore, the auxiliary saw blade assembly also includes a chip removal hole, a plurality of the chip removal holes are opened on the side of the sanding belt, the chip removal holes penetrate the sanding belt and the auxiliary saw blade, and correspond to the position of the baffle plate, and the baffle plate can block the chip removal holes.

[0009] Furthermore, one of the main saw belt wheels is connected to a power source, the other main saw belt wheel is equipped with a movable friction wheel, one of the auxiliary saw belt wheels is equipped with a friction cone wheel, and the friction wheel contacts the friction cone wheel and transmits friction.

[0010] Furthermore, a telescopic rod is provided on the axle of one of the main saw belt wheels, a spring is sleeved on the telescopic rod, a friction wheel is provided at one end of the telescopic rod away from the main saw belt wheel, and the spring is used to push the friction wheel onto the friction cone wheel.

[0011] Furthermore, it also includes a frame and a power source, the main saw frame and the auxiliary saw frame are both connected to the frame, and the power source is arranged on the frame and connected to one of the main saw pulleys of the main saw assembly.

[0012] Furthermore, the main saw frame includes a C-shaped main mounting plate, a main inner baffle plate and a main outer baffle plate, the main inner baffle plate and the main outer baffle plate are arranged on the side of the main mounting plate, and form a main receiving groove for placing the main saw band wheel, and the main inner baffle plate is connected to the processing table.

[0013] Furthermore, a fixing plate arranged opposite to each other is provided in the main accommodating groove, and a mounting groove is formed between the two fixing plates.

[0015] The beneficial effects of the present invention are: The present invention provides an auxiliary sub-saw assembly on the basis of the main saw assembly. When circular cutting is performed on the aluminum alloy plate, the sub-saw assembly is used to pre-process the plate to avoid interference of the plate with the main saw assembly when the main saw assembly subsequently processes the plate, thereby affecting the cutting quality.

[0016] The cutting speed of the secondary saw blade of the present invention is affected by the transmission ratio between the main saw assembly and the secondary saw assembly. According to different circular cutting size requirements, the transmission ratio can be changed by adjusting the position of the secondary saw assembly relative to the main saw assembly, thereby adjusting the rotation speed of the secondary saw blade. Specifically, when the size to be processed is larger, the pre-processed portion is narrower, the transmission ratio of the secondary saw blade becomes smaller accordingly, and the rotation speed is also slowed down accordingly, and vice versa. This makes the cutting process more flexible and can adapt to cutting requirements of different sizes.

[0017] The invention provides a chip discharge hole and a baffle on the secondary saw blade, which can prevent the discharge of debris and dust during the cutting process, and open when no longer restricted by the main saw blade to discharge the debris and dust. During the processing, a support is formed between the main saw blade and the secondary saw blade to prevent the deformation of the saw blade and to prevent the main saw blade and the secondary saw blade from contacting each other, thereby protecting the saw blade and ensuring the stability of the cutting process.

[0023] The embodiment of the present invention provides an aluminum alloy plate self-adaptive cutting device, such as Figure 1-Figure 5 As shown, the cutting device comprises a main saw assembly, a processing table 500 and a secondary saw assembly. The main saw assembly comprises a main saw frame 200, two main saw belt wheels 203 and a main saw blade 204.

[0024] like Figure 1 and Figure 5As shown, the processing table 500 is arranged between the two main saw belt wheels 203, and the main saw blade 204 passes through the processing table 500. The processing table 500 is a plate structure, and a plurality of mutually parallel guide grooves are provided on the processing table 500, and the guide grooves are parallel to the axial direction of the main saw belt wheels 203. The processing table 500 is provided with a processing through groove, and the processing through groove includes a first through groove with a fan-shaped cross section and a second through groove with a straight cross section. The first through groove is arranged at the center of the processing table 500, and the second through groove is parallel to the guide groove and communicates with the inside of the first through groove. The main saw blade 204 and the auxiliary saw blade 401 pass through the first through groove.

[0025] The secondary saw assembly is close to the main saw assembly and is rotatably disposed on the processing table 500 so as to be able to adjust the position of the secondary saw assembly relative to the main saw assembly. The secondary saw assembly includes a secondary saw frame 300, two secondary saw band wheels 303 and a secondary saw blade assembly. The secondary saw blade assembly includes a secondary saw blade 401 and a sanding belt 402. The secondary saw blade 401 is close to the main saw blade 204, and the sanding belt 402 is disposed on the side of the secondary saw blade 401 away from the main saw blade 204.

[0026] When the auxiliary saw blade assembly is adjusted in the use position relative to the main saw blade 204, the auxiliary saw blade 401 will also rotate. Since the cross-section of the first through-groove is a fan-shaped structure, it can provide sufficient rotation space for the auxiliary saw blade 401, so the auxiliary saw blade 401 can rotate in the first through-groove. In addition, the size design of the first through-groove matches the width size design of the auxiliary saw blade 401, ensuring that the auxiliary saw blade 401 and the first through-groove do not interfere with each other while satisfying the rotation of the auxiliary saw blade 401.

[0027] like Figure 5 As shown, when the auxiliary saw blade 401 cuts the plate to be processed, the sanding belt 402 grinds the cutting position to form an avoidance portion on the plate to be processed, so that the main saw blade 204 will not be subjected to the pushing force applied by the plate to be processed when cutting the plate to be processed.

[0028] In this embodiment, when cutting a circle of an aluminum alloy plate, the position of the secondary saw assembly is first adjusted according to the size of the circle to be cut. After the adjustment, the aluminum alloy plate can be placed on the processing table 500 and the power source is started. After the adjustment, the secondary saw blade 401 should be located in front of the main saw blade 204 so that the secondary saw blade 401 can cut the plate first.

[0029] Before the aluminum alloy sheet is cut by the main saw assembly, the auxiliary saw blade 401 on the auxiliary saw assembly will first cut it, and the blocked part will be cleaned in advance to avoid interference when the main saw assembly is cutting. During the processing of the auxiliary saw blade 401, the aluminum alloy sheet is first cut by the auxiliary saw blade 401, and then polished by the sanding belt 402 to form an avoidance portion on the aluminum alloy sheet. After that, the main saw blade 204 cuts the sheet again, and at this time, the main saw blade 204 is located in the avoidance portion to prevent its saw body from being interfered with by the aluminum alloy sheet.

[0030] Specifically, the main saw blade 204 has a certain width and includes a saw blade portion and a saw body portion. When the plate is cut into a circle, the cut circular portion is the finished material portion, and the remaining unnecessary portion is the waste material portion.

[0031] The plate is constantly rotating when the main saw blade 204 is cutting a circle, and the main saw blade 204 cuts the plate in the avoidance portion pre-processed by the secondary saw assembly. Therefore, the finished portion of the plate will not push the saw body of the main saw blade 204 due to the constant change in cutting direction, thereby avoiding deformation of the saw body and affecting processing accuracy and service life.

[0032] The secondary saw assembly of the present invention can pre-cut and grind the plate before the main saw blade 204 cuts, forming an avoidance portion, thereby avoiding the plate from pushing the main saw blade 204 during the cutting process, improving cutting accuracy and efficiency, and reducing saw blade wear.

[0033] In one embodiment, if Figure 1-Figure 3 As shown, the auxiliary saw frame 300 includes a C-shaped auxiliary mounting plate, an auxiliary inner baffle plate and an auxiliary outer baffle plate. The auxiliary inner baffle plate and the auxiliary outer baffle plate are arranged on the side of the auxiliary mounting plate and form an auxiliary accommodating groove for accommodating the auxiliary saw band wheel 303.

[0034] The processing table 500 is provided with an arc-shaped slide groove 501 with the cutting position of the main saw blade 204 as the center. A slider is provided in the slide groove 501, and a screw is installed on the slider. An adjustment connecting column 302 threadedly connected to the screw is provided on the secondary inner baffle. The slider slides in the slide groove 501 by moving the adjustment connecting column 302. Since the adjustment connecting column 302 is connected to the secondary inner baffle of the secondary saw frame 300, the movement of the adjustment connecting column 302 can drive the secondary saw frame 300 to move, so as to change the use position of the secondary saw frame 300, and further adjust the use position of the secondary saw blade assembly on the secondary saw frame 300 relative to the main saw blade 204. Among them, the adjustment connecting column 302 has an internal thread groove.

[0035] In this embodiment, the adjustment process of the secondary saw frame 300 is that the user holds the adjustment connecting column 302 and moves the adjustment connecting column 302, and the movement of the adjustment connecting column 302 drives the slider to move along the slide groove 501. During the entire adjustment process, the slider moves along the slide groove 501 to limit the adjustment path of the adjustment connecting column 302.

[0036] At the same time, because the secondary inner baffle of the secondary saw frame 300 is connected to the adjustment connecting column 302, the adjustment connecting column 302 drives the secondary saw frame 300 to move accordingly, so as to adjust the position of the secondary saw frame 300 relative to the main saw blade 204, and then adjust the use position of the secondary saw blade 401 on the secondary saw frame 300. The movement of the adjustment connecting column 302 is centered on the cutting position of the main saw blade 204.

[0037] During the adjustment process, since the cross section of the first through slot where the secondary saw blade 401 is located is a fan-shaped structure, and the size design of the first through slot matches the width size design of the secondary saw blade 401, the first through slot can provide sufficient rotation space for the secondary saw blade 401, and the secondary saw blade 401 can rotate in the first through slot. While meeting the requirement that the secondary saw blade 401 can rotate in the first through slot, the present invention can also ensure that the secondary saw blade 401 and the first through slot do not interfere with each other.

[0038] After adjustment, the secondary saw frame 300 can be fixed using existing technical means. For example, a horizontal mounting plate is provided on the lower end of the secondary saw frame 300, and a rotatable tightening bolt is provided on the mounting plate, and one end of the tightening bolt can be pressed against the mounting surface of the secondary saw frame 300 (such as the top surface of the frame 100 or the floor of the factory building) to fix the secondary saw frame 300 on the mounting surface. Therefore, before adjusting the position of the secondary saw frame 300, the tightening bolt is first turned upward to release the restriction on the secondary saw frame 300 so that the secondary saw frame 300 can rotate relative to the mounting surface. After the position of the secondary saw frame 300 is adjusted, the tightening bolt is turned downward again, and one end of the tightening bolt can be pressed against the mounting surface, thereby preventing the secondary saw frame 300 from rotating.

[0039] By adjusting the use position of the secondary saw frame 300 using the adjusting connecting column 302, the secondary saw frame 300 can be accurately positioned at the required cutting position to adapt to processing of different sizes, and the device can be used in scenarios including but not limited to straight line cutting and curve cutting.

[0040] The present invention adjusts the position of the slider in the slide groove 501 to change the use position of the adjustment connecting column 302 and the auxiliary saw frame 300 fixedly connected thereto, thereby changing the use position of the auxiliary saw blade 401 arranged on the auxiliary saw frame 300, so that the auxiliary saw blade 401 maintains a suitable distance from the main saw blade 204 to adapt to different cutting tasks, thereby improving the adaptability and flexibility of the device.

[0041] In one embodiment, if Figure 6 and Figure 7 As shown, the secondary saw blade assembly further includes a resettable baffle 404, which is disposed on a side of the secondary saw blade 401 close to the main saw blade 204, and one end of the baffle 404 presses against the side of the main saw blade 204 to form a support between the main saw blade 204 and the secondary saw blade 401. The baffle 404 is mounted on the secondary saw blade 401 through an elastic sheet, so that the baffle 404 has a tendency to lift up to a certain angle in the absence of external force.

[0042] Specifically, during the cutting process, one end of the baffle 404 is connected to the auxiliary saw blade 401, and the other end is pressed against the side of the main saw blade 204, playing a supporting role between the two saw blades, effectively supporting the main saw blade 204 and the auxiliary saw blade 401, ensuring stability during the cutting process, while also preventing the auxiliary saw blade 401 from colliding with the main saw blade 204, preventing the saw blade from deforming, and extending the service life of the saw blade.

[0043] In one embodiment, if Figure 7 As shown, the auxiliary saw blade assembly also includes a chip removal hole 403. A plurality of chip removal holes 403 are opened on the side of the sanding belt 402. The chip removal holes 403 pass through the sanding belt 402 and the auxiliary saw blade 401 and correspond to the position of the baffle plate 404. The baffle plate 404 can block the chip removal holes 403.

[0044] Specifically, during the cutting process of the secondary saw blade 401 and the grinding process of the abrasive belt 402, the debris enters the chip removal hole 403 to be collected, preventing excessive debris from accumulating on the plate and affecting subsequent processing, and at this time, the baffle 404 blocks the chip removal hole 403 to prevent the debris from splashing. When the secondary saw blade 401 continues to move to a separation state with a certain distance between it and the main saw blade 204, the baffle 404 is no longer hindered by the main saw blade 204, and it opens under the action of the elastic sheet to allow the debris in the chip removal hole 403 to fall.

[0045] The chip removal hole 403 of the present invention can collect the debris in the cutting process to prevent the accumulation of debris and affect the cutting effect. At the same time, the baffle 404 can block the chip removal hole 403 to prevent the debris from splashing, thereby improving the safety of the working environment.

[0046] The cutting speed of the secondary saw blade 401 of the present invention is affected by the transmission ratio between the main saw assembly and the secondary saw assembly. According to different circular cutting size requirements, the transmission ratio can be changed by adjusting the position of the secondary saw assembly relative to the main saw assembly, thereby adjusting the rotation speed of the secondary saw blade 401.

[0047] Specifically, when the size of the circle to be processed is larger, the pre-processed portion (the portion that will interfere with the main saw blade 204) is narrower, the transmission ratio of the auxiliary saw blade 401 becomes smaller accordingly, and the rotation speed also slows down accordingly. Conversely, when the size of the circle to be processed is smaller, the pre-processed portion is wider, the transmission ratio of the auxiliary saw blade 401 becomes larger accordingly, and the rotation speed also speeds up accordingly.

[0048] Therefore, in some embodiments, Figure 3 and Figure 4 As shown, one of the main saw belt wheels 203 is connected to the power source, the other main saw belt wheel 203 is equipped with a movable friction wheel 202, and one of the auxiliary saw belt wheels 303 is equipped with a friction cone wheel 301, and the friction wheel 202 contacts the friction cone wheel 301 and transmits friction.

[0049] Among them, Figure 4 As shown, the diameter of the friction cone wheel 301 increases in a direction away from the secondary saw frame 300. The outer edge of the friction wheel 202 is rounded to ensure effective contact between the friction wheel 202 and the friction cone wheel 301.

[0050] In this embodiment, the power source drives the main saw belt wheel 203 to rotate, so that the friction wheel 202 rotates, and the friction wheel 202 contacts the friction cone wheel 301, so that the friction cone wheel 301 rotates, so as to transmit the power of the main saw assembly to the auxiliary saw belt wheel 303, thereby driving the auxiliary saw blade 401 to cut.

[0051] The present invention can realize the driving of the auxiliary saw blade 401 through the contact and friction transmission between the friction wheel 202 and the friction cone wheel 301, so that the rotation of the auxiliary saw blade 401 is more stable, the cutting accuracy and efficiency are improved, and the cutting process is more flexible, which can meet the cutting requirements of different circular sizes.

[0052] In addition, in this embodiment, a plurality of weight-reducing holes are provided on the main saw band wheel 203, the auxiliary saw band wheel 303, the friction wheel 202 and the friction cone wheel 301. The design of the weight-reducing holes reduces the weight of the saw band wheel, reduces the moment of inertia, makes the start and stop of the saw band wheel faster, and improves the response speed and energy-saving effect of the cutting device.

[0053] In one embodiment, if Figure 4 As shown, a telescopic rod 201 is provided on the axle of a main saw belt wheel 203, a spring is sleeved on the telescopic rod 201, and a friction wheel 202 is provided at one end of the telescopic rod 201 away from the main saw belt wheel 203, and the spring is used to push the friction wheel 202 onto the friction cone wheel 301.

[0054] In this embodiment, the spring pushes the friction wheel 202 against the friction cone wheel 301 to ensure effective contact between the two, so as to ensure the realization of friction transmission. When the secondary saw assembly rotates, it causes the position of the friction cone wheel 301 to change. At this time, the spring can automatically adjust the pressure to always press the friction wheel 202 against the friction cone wheel 301, maintain stable transmission, and improve the reliability and stability of the device.

[0055] In one embodiment, if Figure 1-Figure 3 As shown, it also includes a frame 100 and a power source, the main saw frame 200 and the auxiliary saw frame 300 are both connected to the frame 100, and the power source is arranged on the frame 100 and connected to one of the main saw belt wheels 203 of the main saw assembly. Among them, the frame 100 and the main saw assembly are common vertical sawing machines, the power source is a motor 101, and one of the main saw belt wheels 203 is directly connected to the motor 101 as a main transmission wheel.

[0056] The main saw frame 200 is fixedly connected to the frame 100, and the auxiliary saw frame 300 is slidably connected to the frame 100. Figure 1 As shown, the auxiliary saw frame 300 also has a support leg slidably connected to the frame 100, and a support slide is provided on the frame 100. The support slide is an arc-shaped structure and is centered on the cutting position of the main saw blade 204. The support slide is slidably matched with the support leg of the auxiliary saw frame 300 to ensure that when the use position of the auxiliary saw frame 300 is adjusted, the auxiliary saw frame 300 can rotate around the cutting position of the main saw blade 204.

[0057] The main saw frame 200 and the auxiliary saw frame 300 of the present invention are connected to the frame 100. The power source is arranged on the frame 100 and connected to a main saw belt wheel 203 of the main saw assembly to provide power for the entire cutting device, making the structure of the entire cutting device more stable.

[0058] In one embodiment, if Figure 1-Figure 3 As shown, the main saw frame 200 includes a C-shaped main mounting plate, a main inner baffle plate and a main outer baffle plate, so that the main saw frame 200 is a C-shaped structure as a whole. The main inner baffle plate and the main outer baffle plate are arranged on the side of the main mounting plate, and form a main receiving groove for placing the main saw band wheel 203, and the main inner baffle plate is connected to the processing table 500.

[0059] In this embodiment, the main saw belt wheel 203 is placed in the main receiving groove, and the main inner baffle is connected to the processing table 500 by bolts to provide support for the processing table 500. The C-shaped design of the main saw frame 200 provides enough space to place the main saw belt wheel 203 and the processing table 500, and the connection between the main inner baffle and the processing table 500 enhances the stability of the entire device.

[0060] And, if Figure 3As shown, oppositely arranged fixing plates are provided in the main receiving groove, and an installation groove is formed between the two fixing plates. A mounting seat is provided in the installation groove, and the mounting seat is connected to a main saw belt wheel 203. An adjusting rod is provided on the outer peripheral wall of the mounting seat, and the adjusting rod is threadedly connected to the main outer baffle.

[0061] In this embodiment, the position of the mounting base can be adjusted by rotating the adjusting rod, thereby adjusting the position of the main saw band wheel 203 to adjust the tension of the main saw blade 204 .

[0062] In summary, the working process of the aluminum alloy sheet adaptive cutting device is as follows: The main saw blade 204 has a certain width and includes a saw blade portion and a saw body portion. When the plate is cut into a circle, the cut circular portion is the finished material portion, and the remaining unnecessary portion is the waste material portion.

[0063] On this basis, when cutting the aluminum alloy plate in a circle, first adjust the position of the secondary saw assembly according to the size of the circle to be cut. The adjustment process is as follows: The user holds the adjustment connecting column 302 and moves the adjustment connecting column 302, and the movement of the adjustment connecting column 302 drives the slider to move along the slide groove 501. During the entire adjustment process, the slider moves along the slide groove 501 to limit the adjustment path of the adjustment connecting column 302.

[0064] At the same time, because the secondary inner baffle of the secondary saw frame 300 is connected to the adjustment connecting column 302, the adjustment connecting column 302 drives the secondary saw frame 300 to move accordingly, so as to adjust the position of the secondary saw frame 300 relative to the main saw blade 204, and then adjust the use position of the secondary saw blade 401 on the secondary saw frame 300. The movement of the adjustment connecting column 302 is centered on the cutting position of the main saw blade 204.

[0065] During the whole adjustment process, the slider moves along the slide slot 501 to limit the adjustment path of the connecting column 302. During the adjustment process, due to the structure and size design of the first through slot, the secondary saw blade 401 can rotate in the first through slot without interfering with the first through slot.

[0066] After debugging, the secondary saw frame 300 is fixed. At this time, the secondary saw blade 401 should be located in front of the main saw blade 204 so that the secondary saw blade 401 cuts the plate first. In addition, the transmission ratio of the friction wheel 202 and the friction cone wheel 301 meets the speed requirement of the part to be polished.

[0067] The aluminum alloy plate is placed on the processing table 500, and the power source is started. The motor 101 drives the main saw belt wheel 203, the main saw blade 204 and the friction wheel 202 to rotate, and the rotation of the friction wheel 202 causes the friction cone wheel 301 to rotate accordingly, and the rotation of the friction cone wheel 301 causes the auxiliary saw belt wheel 303 and the auxiliary saw blade 401 to rotate, so as to cut and grind the plate.

[0068] Before the aluminum alloy plate is cut by the main saw assembly, it will be cut by the auxiliary saw assembly first, and the blocked part will be cleaned first to form an avoidance part, and then the main saw blade 204 will cut the plate. The cutting process is as follows: the aluminum alloy plate is first cut by the auxiliary saw blade 401, and then polished by the sanding belt 402 to form an avoidance part on the aluminum alloy plate. The polished debris and dust enter the chip discharge hole 403, but are blocked by the baffle 404. At this time, the auxiliary saw blade 401 and the main saw blade 204 are against each other, and the baffle 404 cannot be opened, so the debris and dust remain in the chip discharge hole 403; when the auxiliary saw blade 401 continues to rotate until it is separated from the main saw blade 204 with a certain distance, the baffle 404 pops open, and the debris and dust are discharged from the chip discharge hole 403.

[0069] The plate is constantly rotating when the main saw blade 204 is cutting a circle, and the main saw blade 204 cuts the plate in the avoidance portion pre-processed by the secondary saw assembly. Therefore, the finished portion of the plate will not push the saw body of the main saw blade 204 due to the constant change in cutting direction, thereby avoiding deformation of the saw body and affecting processing accuracy and service life.

[0070] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
