Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe cutting, in particular to a cutting device for seamless steel pipe production. Background Art

[0002] Steel pipe cutting is a crucial step in steel pipe processing. Its primary purpose is to precisely cut steel pipes to predetermined dimensions to meet diverse engineering and process requirements. Steel pipe cutting not only impacts material utilization but also the quality and production efficiency of the final product. Therefore, selecting the appropriate cutting method and equipment is crucial. Steel pipe cutting methods vary, including manual cutting, mechanical cutting, flame cutting, and plasma cutting. The most common method is mechanical cutting, which utilizes specialized machinery such as pipe cutters and band saws. Mechanical cutting offers high efficiency and precision, making it suitable for batch cutting and large-scale steel pipe cutting.

[0003] A Chinese patent with authorization announcement number CN116140690B discloses a fixed-length cutting device for the production of small-diameter steel pipes, including: a positioning plate, the positioning plate is vertically connected to the mounting beam, and a cutting machine is provided on the mounting beam; a mounting groove is provided on the side wall of the mounting cylinder, and a fixing part is provided on the inner wall of the mounting cylinder; wherein, the elastic telescopic rod is adapted to the mounting beam, and the positioning plate is adapted to the mounting cylinder. The patent first rotates the motor to drive the cutting piece for cutting, and first cuts the pipe body located on the front side. After cutting, the cutting piece is controlled to reverse and cut the pipe body on the rear side, thereby realizing fixed-length cutting of the small-diameter steel pipe; the cut pipe body is located on the buffer mechanism, thereby realizing the reception of the cut small-diameter steel pipe, and the connecting shaft is driven to rotate through the conveyor belt, so that the material dividing plate rotates, thereby realizing the classified discharge of the cut small-diameter steel pipe.

[0004] When batch processing steel pipes, due to the large number of single cuts, more chips will fall into the gaps between adjacent steel pipes. Moreover, as the cutting time increases, the closer the steel pipe is to the bottom, the more chips there are in the gap. During the saw cutting process, not only will the saw wear be increased, but the chips will also affect the cutting effect of the steel pipe end face, resulting in cuts or burrs on the steel pipe end face, reducing the dimensional accuracy of the steel pipe. Summary of the Invention

[0005] The present invention provides a cutting device for seamless steel pipe production, which aims to solve the technical problem in the related art that when batch processing of steel pipes is carried out, a large number of chips will fall into the gaps between adjacent steel pipes due to the large number of single cuts, and as the cutting time increases, the closer the steel pipe is to the bottom, the more chips there are in the gaps. During the saw cutting process, not only will the wear of the saw be aggravated, but the chips will also affect the cutting effect of the end face of the steel pipe, resulting in cut marks or burrs on the end face of the steel pipe, thereby reducing the dimensional accuracy of the steel pipe.

[0006] The present invention provides a cutting device for seamless steel pipe production, comprising: a base, a positioning module and a cutting module arranged on the base, the cutting module comprising a cutting frame vertically slidingly assembled on the base, a driving wheel arranged on the cutting frame and a knife saw, and a cleaning module is also provided on the cutting frame; the cleaning module comprises two left and right mounting seats fixed to the front side of the cutting frame, a connecting plate is vertically elastically slidably connected inside the mounting seat, a perforation is provided on the rear side of the connecting plate, and a push plate is provided on the mounting seat at a position corresponding to the perforation; a front bearing seat and a rear bearing seat are vertically slidably matched inside the mounting seat, and the front bearing seat and the rear bearing seat slide vertically elastically The front supporting seat is connected, and the perforations correspond to the rear supporting seat. There are through-holes on both sides of the front supporting seat. A cleaning roller is rotatably installed on the inner side of the front supporting seat. A rotating shaft passing through the long holes is provided on both sides of the cleaning roller through a one-way rotating structure. A rotating seat elastically connected to the front supporting seat is rotatably installed on the rotating shaft. The rear supporting seat is provided with an abutment portion for pushing the rotating seat to slide forward and a pushing portion for pushing the cut steel pipe forward. A transmission structure for driving the rotating shaft to rotate is provided between the rotating shaft on one side and the mounting seat. A sliding seat is provided to slide back and forth inside the front supporting seat, and a force storage member connected to the cleaning roller is provided on the sliding seat.

[0007] Beneficial effect: As the saw cuts downward, the cleaning roller remains in place, causing the connecting spring to be compressed. The cleaning roller abuts against the steel pipe, which can ensure the stability of the cut part and avoid being pulled by the saw. After the steel pipe falls, the connecting spring will quickly release the elastic force, causing the connecting plate to push the rear bearing seat and the front bearing seat downward. During this process, the rear bearing seat and the front bearing seat are reset, and the reset spring pushes the rotating shaft and the cleaning roller to move backward to reset. After the rotating shaft moves to the rear side, the gear engages with the rack, and the gear drives the rotating shaft to rotate. At this time, the rotating shaft will drive the cleaning roller to rotate together, and at the same time, the force storage member will store force. When the cleaning roller reaches the bottom, the gear reaches under the rack and disengages from it. Then the force storage member releases the elastic force, driving the cleaning roller to rotate. The cleaning roller can clean up the debris that falls between the two adjacent steel pipes on the left and right. This cycle completes the cutting of all steel pipes. When the steel pipe is almost cut, the cleaning roller comes into contact with the steel pipe to prevent the steel pipe from being pulled by the saw and causing the part that is about to be cut to be torn off directly, thereby preventing the steel pipe from being thrown out and the cut end surface from being uneven. At the same time, it can clean up the debris between two adjacent steel pipes, effectively improving the cutting effect of the steel pipe end surface.

[0008] Preferably, the mounting seat is provided with left and right through holes near the bottom, and a connecting spring is provided in the through hole. The connecting spring is vertically arranged, and the lower end of the connecting spring is fixedly connected to the connecting plate, and the bottom of the connecting plate abuts against the upper surface of the front bearing seat and the rear bearing seat.

[0009] The effect is that the through hole can ensure that both ends of the front bearing seat and the rear bearing seat are inserted, so that the bottom of the connecting plate abuts against the upper surfaces of the front bearing seat and the rear bearing seat.

[0010] Preferably, the lower end of the push plate extends into the through hole of the mounting seat, and the push plate and the mounting seat are slidably matched. A fixing hole is provided on the push plate, and a socket is provided on the mounting seat at a position corresponding to the fixing hole.

[0011] The effect is that the pushing plate can move up and down to adjust the length of the pushing plate inserted into the through hole, thereby adjusting the distance the bearing seat moves after pushing.

[0012] Preferably, the pushing portion is a right-angled triangle structure, which is horizontally arranged along the left and right directions. The pushing portion has two adjacent right-angled surfaces and an inclined surface. The two adjacent right-angled surfaces are respectively located at the top and the rear side, and the inclined surface is located at the front side, and the inclined surface gradually tilts downward from front to rear.

[0013] The effect is that the pushing part can be inserted downward into the gap formed after the steel pipe is cut, thereby pushing the cut steel pipe toward the front side to make it fall.

[0014] Preferably, the one-way rotation structure is a one-way gear.

[0015] Preferably, the force storage member is a coil spring installed on the sliding seat, one end of the coil spring is connected to the sliding seat, and the other end of the coil spring is connected to the cleaning roller.

[0016] The effect is that the coil spring can store force, and when the cleaning roller reaches the bottom, the coil spring drives the cleaning roller to rotate.

[0017] Preferably, the swivel seat is a square structure, and a return spring extending in the front-to-back direction is fixedly connected to the swivel seat, and one end of the return spring away from the swivel seat is connected to the front bearing seat.

[0018] Preferably, a discharging rack is fixedly mounted on the front side of the base, and an adjustment plate is slidably mounted on the discharging rack.

[0019] Preferably, two fixing plates are arranged on the cutting frame at intervals along the left and right directions, and the bottom of each fixing plate is provided with a left and right through groove, and the saw blade passes through the grooves of the two fixing plates, and the mounting seat is fixed on the fixing plate.

[0020] Preferably, a conveying frame is provided at the rear side of the base, and a plurality of rollers rotating along the left-right axis are provided at intervals in the front and rear directions on the conveying frame.

[0021] By adopting the above technical solution, the beneficial effects of the present invention are as follows: as the saw cuts downward, the cleaning roller remains in place, so that the connecting spring is compressed, and the cleaning roller abuts against the steel pipe, which can ensure the stability of the cut part and avoid being pulled by the saw. After the steel pipe falls, the connecting spring will quickly release the elastic force, so that the connecting plate pushes the rear bearing seat and the front bearing seat downward. During this process, the rear bearing seat and the front bearing seat complete reset, and the reset spring pushes the rotating shaft and the cleaning roller to move to the rear side to reset. After the rotating shaft moves to the rear side, the gear and the rack engage, and the gear drives the rotating shaft to rotate. At this time, the rotating shaft will drive the cleaning roller to rotate together, and at the same time, the force storage member is charged. When the cleaning roller reaches the bottom, the gear reaches below the rack and disengages from it, and then the force storage member releases the elastic force, driving the cleaning roller to rotate. The cleaning roller can clean up the debris that falls between the two adjacent steel pipes on the left and right, and this cycle is used to complete the cutting of all steel pipes. When the steel pipe is almost cut, the cleaning roller comes into contact with the steel pipe to prevent the steel pipe from being pulled by the saw and causing the part that is about to be cut to be torn off directly, thereby preventing the steel pipe from being thrown out and the cut end surface from being uneven. At the same time, it can clean up the debris between two adjacent steel pipes, effectively improving the cutting effect of the steel pipe end surface. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0036] like Figures 1 to 11 As shown, a specific embodiment of a cutting device for seamless steel pipe production according to the present invention includes a carrying module, a positioning module, a cutting module, a blanking module and a cleaning module.

[0037] like Figure 1 and Figure 2 As shown, the carrying module includes a base 10 , a bracket 11 , a conveying frame 30 and a roller 31 .

[0038] The base 10 is rectangular and extends longitudinally in the left-right direction. A bracket 11 is fixedly mounted on the upper surface of the base 10 and has an L-shaped structure. A conveyor frame 30 is mounted on the rear side of the base 10. The conveyor frame 30 is also rectangular and extends longitudinally in the front-to-back direction. A plurality of rollers 31 are arranged at intervals along the front-to-back direction on the conveyor frame 30. The axes of the rollers 31 extend in the left-to-right direction and are capable of conveying steel pipes.

[0039] The positioning module includes a vertical positioning unit and a horizontal positioning unit.

[0040] like Figure 2As shown, the vertical positioning unit includes a clamping cylinder 12 fixedly mounted on the upper surface of the bracket 11, and a pressure plate 13 is fixedly mounted on the telescopic portion of the clamping cylinder 12. The clamping cylinder 12 can drive the pressure plate 13 to move up and down, thereby clamping and positioning the steel pipe in the vertical direction.

[0041] like Figure 3 As shown, the horizontal positioning unit includes a positioning plate 14 mounted on the base 10 for horizontal sliding in the left-right direction. The positioning plate 14 corresponds to the vertical surface of the bracket 11. A positioning cylinder 15 is fixedly mounted on the base 10. The telescopic portion of the positioning cylinder 15 is fixedly connected to the positioning plate 14, thereby driving the positioning plate 14 to slide horizontally, thereby clamping the steel pipe on the vertical surface of the bracket 11. The steel pipe is positioned by the vertical clamping and positioning of the pressure plate 13 and the horizontal clamping and positioning of the positioning plate 14.

[0042] like Figure 1 、 Figure 2 、 Figure 4 As shown, the cutting module includes a slide column 40 , a cutting frame 41 , a lifting cylinder 42 , a carrying box 43 , a driving wheel 44 , a saw blade 45 and a fixing plate 46 .

[0043] A sliding column 40 is fixedly installed on the base 10, and the sliding column 40 is vertically arranged. A cutting frame 41 is vertically slidably installed on the sliding column 40. A lifting cylinder 42 is also fixedly installed on the base 10. The telescopic part of the lifting cylinder 42 is fixedly connected to the cutting frame 41. The lifting cylinder 42 is used to drive the cutting frame 41 to rise and fall along the sliding column 40.

[0044] A carrier box 43 is symmetrically mounted on each side of the cutting frame 41. The carrier boxes 43 are fixedly connected to the cutting frame 41 and are tilted. In this embodiment, the carrier boxes 43 gradually tilt upward from front to back. Drive wheels 44 are rotatably mounted on each carrier box 43, one of which is driven by a motor. A saw blade 45 is mounted on the outside of the two drive wheels 44. Rotation of the two drive wheels 44 drives the saw blade 45, which in turn, in conjunction with a lift cylinder 42, raises and lowers the cutting frame 41, completing the cutting of the steel pipe.

[0045] Two fixed plates 46 are spaced apart on the cutting frame 41, each fixedly mounted on the cutting frame 41. Each fixed plate 46 has a square groove at its bottom, extending from left to right. The saw blade 45 passes through the grooves of the two fixed plates 46, limiting the position of the saw blade 45 and improving its stability during cutting. This also ensures that the portion of the saw blade 45 that is cut by the saw blade 45 remains vertical, that is, the portion of the saw blade 45 between the left and right fixed plates 46 remains vertical. It is important to emphasize that the above-described structure and principles are prior art and will not be elaborated upon here.

[0046] Continue back Figure 1 The unloading module includes a discharge rack 20 fixedly mounted on the front side of the base 10. This U-shaped structure comprises a bottom plate and two vertical plates. The bottom plate of the discharge rack 20 is tilted, gradually sloping upward from front to back, facilitating the discharge of cut and dropped steel pipes to the outside of the device. The two vertical plates are spaced apart in a vertical arrangement, each providing a shield to prevent the steel pipes from being thrown out during the cutting process.

[0047] An adjustment plate 21 is installed on the discharge rack 20 for sliding left and right. The adjustment plate 21 slides with the bottom plate of the discharge rack 20, and bolts are provided on the discharge rack 20 to fix the adjustment plate 21, so that the position of the adjustment plate 21 can be moved left and right to adapt to different numbers of steel pipes.

[0048] The cleaning module includes a carrying unit and a cleaning unit. The carrying unit includes a mounting seat 50 , a connecting spring 51 , a connecting plate 52 and a pushing plate 54 .

[0049] like Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, two mounting blocks 50 are provided, fixedly mounted on the front sides of the two fixing plates 46, and the two mounting blocks 50 are arranged horizontally. Each mounting block 50 has a through hole extending horizontally from left to right near the bottom. Each through hole contains a connecting spring 51. The connecting spring 51 is vertically arranged, with the upper end of the connecting spring 51 fixedly connected to the top wall of the through hole. The lower end of the connecting spring 51 is fixedly mounted with a connecting plate 52, which slides vertically within the through hole. A through hole 53 extending vertically is provided in the middle of the connecting plate 52, near the rear.

[0050] A push plate 54 is vertically slidably mounted within the mounting base 50, with the lower end of the push plate 54 extending into the through-hole. The push plate 54 has a handle, and the mounting base 50 has an opening on the front. The handle of the push plate 54 extends through the opening in the mounting base 50 to the outside, allowing for manual adjustment of the height of the push plate 54. The push plate 54 is provided with fixing holes 55, and a plurality of insertion holes 56 are vertically spaced apart on the front of the mounting base 50. The push plate 54 is secured by manually adjusting the position of the push plate 54 so that the fixing holes 55 align with the insertion holes 56. Then, a pin is inserted through the insertion holes 56 and into the fixing holes 55.

[0051] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 as well as Figure 11As shown, the cleaning unit includes a rear supporting seat 60, a pushing portion 61, an abutting portion 62, a front supporting seat 70, a supporting portion 71, a cleaning roller 73, a rotating shaft 74, a rotating seat 75, a return spring 76, a side plate 77, a gear 80, a rack 81, a sliding seat 82 and a force storage member 83.

[0052] Inside the two mounting blocks 50 are disposed a rear support block 60 and a front support block 70, both of which slide within the through-holes of the two mounting blocks 50. The rear support block 60 is located behind the front support block 70, and the two are vertically elastically slidably engaged, sliding up and down between them via a slider and a slide groove, with a spring (not shown) disposed between them.

[0053] Support portions 71 are provided on both the left and right sides of the rear support seat 60 and the front support seat 70. Each support portion 71 is a rectangular structure. The upper surfaces of the rear support seat 60 and the front support seat 70 are flush, and the upper surfaces of the support portions 71 of the two are also flush. The support portions 71 on both sides of the rear support seat 60 and the front support seat 70 are respectively inserted into the through holes of the mounting seats 50 on both sides. That is, the support portions 71 on the left side of the rear support seat 60 and the front support seat 70 are both inserted into the through holes of the mounting seat 50 on the left side, and the support portions 71 on the right side of the rear support seat 60 and the front support seat 70 are both inserted into the through holes of the mounting seat 50 on the right side.

[0054] The support parts 71 are vertically slidably engaged with the through holes of the mounting seat 50, that is, the support parts 71 on the rear supporting seat 60 abut and slide with the rear side wall of the through hole of the mounting seat 50, and the front supporting seat 70 abut and slide with the front side wall of the through hole of the mounting seat 50, thereby ensuring the stability of the rear supporting seat 60 and the front supporting seat 70, so that the two can only move up and down.

[0055] In the initial state, the connection spring 51 is in a released state, and the lower surface of the connection plate 52 abuts against the upper surface of the support portion 71 , thereby fixing the rear bearing seat 60 and the front bearing seat 70 to prevent them from shaking.

[0056] A pusher 61 is provided at the bottom of the rear support 60. This pusher 61 is a right-angled triangle, arranged horizontally in the left-right direction. It has two adjacent right-angled surfaces and an inclined surface. The two adjacent right-angled surfaces are located at the top and rear, respectively, while the inclined surface is located at the front, gradually sloping downward from front to back.

[0057] Abutment portions 62 are provided on both left and right sides of the rear supporting seat 60 . The front sides of the abutment portions 62 are inclined surfaces, and the inclined surfaces of the abutment portions 62 gradually slope downward from the front to the rear.

[0058] The left and right side walls of the front bearing seat 70 are both provided with a long hole 72 that passes through the left and right sides. The long hole 72 is a long strip structure, and its length direction extends along the front-back direction (such as Figure 11 A cleaning roller 73 is rotatably mounted on the inner side of the front bearing seat 70 . The axis of the cleaning roller 73 is arranged horizontally along the left-right direction, and the cleaning roller 73 is covered with bristles. In this embodiment, the bristles are made of nylon.

[0059] It is particularly emphasized that the lower end of the pusher portion 61 is higher than the horizontal plane where the axis of the cleaning roller 73 is located, thereby leaving enough space for the pusher portion 61 to descend.

[0060] A rotating shaft 74 is provided on both the left and right sides of the cleaning roller 73. The rotating shaft 74 is connected to the cleaning roller 73 through a one-way rotation structure (not shown in the figure). The one-way rotation structure is a one-way gear, and the rotating shafts 74 on both sides pass through the avoidance long holes 72 on the left and right sides respectively. It is particularly emphasized that the height of the avoidance long hole 72 is the same as the diameter on the rotating shaft 74, so that the rotating shaft 74 can slide back and forth in the avoidance long hole 72.

[0061] A swivel base 75 is rotatably mounted on each of the left and right rotating shafts 74. The swivel base 75 is capable of rotating about the axis of the rotating shaft 74. In this embodiment, the swivel base 75 has a square structure. A return spring 76 is provided on the front side of each swivel base 75. Side plates 77 are fixedly mounted on both sides of the front bearing seat 70. The end of the return spring 76 away from the swivel base 75 is fixedly connected to the side plate 77 on that side.

[0062] When the rear supporting seat 60 descends along the front supporting seat 70, the inclined surface of the abutting portion 62 of the rear supporting seat 60 will push the rotating seat 75, causing the rotating seat 75 to drive the cleaning roller 73 to slide forward. At this time, the return spring 76 will be compressed. When the rear supporting seat 60 rises and resets, the return spring 76 is released, causing the cleaning roller 73 to slide backward and reset.

[0063] A gear 80 is provided on the right rotating shaft 74 , and a rack 81 is provided in the through hole on the right mounting seat 50 at a position corresponding to the gear 80 . In the initial state, the gear 80 is located below the rack 81 and the two are not engaged.

[0064] like Figure 8 As shown, a sliding seat 82 is mounted on the right side wall inside the front bearing seat 70 for forward and backward sliding movement. The sliding seat 82 has an opening for the rotation shaft 74 to pass through. A force storage member 83 is provided on the sliding seat 82. In this embodiment, the force storage member 83 is a coil spring, with one end connected to the sliding seat 82 and the other end connected to the cleaning roller 73. When the rotation shaft 74 drives the cleaning roller 73 to rotate, the coil spring accumulates force.

[0065] During operation, multiple rows of vertically stacked steel pipes are delivered to the inside of the support 11 via the conveyor frame 30. The steel pipes are positioned vertically by the pressure plate 13 and horizontally by the positioning plate 14. The lifting cylinder 42 then drives the cutting frame 41 downward, and the saw blade 45 begins cutting the steel pipe. When the saw blade 45 contacts the steel pipe, the cleaning roller 73 also abuts the steel pipe. As the saw blade 45 cuts downward, the cleaning roller 73 remains in place. As the mounting base 50 continues to descend, the connecting plate 52 abuts the support portion 71, compressing the connecting spring 51. The contact between the cleaning roller 73 and the steel pipe ensures the stability of the cut portion and prevents it from being pulled by the saw blade 45. Specifically, when the steel pipe is nearly cut, the saw blade 45 prevents the steel pipe from being pulled by the pipe and directly ripping off the nearly cut portion, which would cause the steel pipe to be thrown out and have an uneven end surface. During the descent of the mounting base 50 , the gear 80 engages with the rack 81 , causing the shaft 74 to rotate. However, since the shaft 74 is connected to the cleaning roller 73 via a one-way rotation structure, the shaft 74 does not drive the cleaning roller 73 to rotate.

[0066] When the saw blade 45 is about to finish cutting the row of steel pipes being cut, the pushing plate 54 will pass through the through-hole 53 and abut against the rear supporting seat 60, thereby pushing the rear supporting seat 60 to descend, and the rear supporting seat 60 will descend along the front supporting seat 70. When the abutting portion 62 on the rear supporting seat 60 abuts against the rotating seat 75, the row of steel pipes being cut will be cut off. As the saw blade 45 continues to descend and starts cutting the next row of steel pipes, the rear supporting seat 60 will be lowered, and the abutting portion 62 will push the rotating seat 75 to slide forward. The rotating seat 75 drives the cleaning roller 73 to slide forward, and the cleaning roller 73 will push the part of the front end of the steel pipe cut forward. At the same time, the pushing portion 61 will also be inserted into the gap at the cutting position of the steel pipe, and the inclined surface on the front side of the pushing portion 61 will also push the part of the front end of the steel pipe cut forward until the cut steel pipe is pushed down. It should be noted that when the saw blade 45 continues to descend and starts cutting the next row of steel pipes, since debris falls into the gap between the two steel pipes, the saw blade 45 needs to cut to a certain depth before it contacts the debris. The saw blade 45 will not contact the debris when it first starts cutting the steel pipes.

[0067] After the steel pipe falls, the connecting spring 51 will quickly release its elastic force, causing the connecting plate 52 to push the rear bearing seat 60 and the front bearing seat 70 downward. During this process, the rear bearing seat 60 and the front bearing seat 70 complete their reset, that is, the rear bearing seat 60 will rise relative to the front bearing seat 70. The reset spring 76 pushes the rotating shaft 74 and the cleaning roller 73 to move to the rear side and reset. After the rotating shaft 74 moves to the rear side, the gear 80 engages with the rack 81, and the gear 80 drives the rotating shaft 74 to rotate. At this time, the rotation of the rotating shaft 74 will drive the cleaning roller 73 to rotate together, and at the same time, the force storage member 83 is stored. When the cleaning roller 73 reaches the bottom, that is, the cleaning roller 73 contacts the row of steel pipes being cut, the gear 80 reaches below the rack 81 and disengages from it, and then the force storage member 83 releases its elastic force, driving the cleaning roller 73 to rotate. The cleaning roller 73 can clean up the debris that falls between the two adjacent steel pipes on the left and right sides, and in this cycle, complete the cutting of all steel pipes.

[0068] Although the embodiments of the present invention have been shown and described above, it will be understood that the above embodiments are illustrative and are not to be construed as limitations on the present invention. A person skilled in the art may change, modify, replace and modify the above embodiments within the scope of the present invention.
