Description

Technical Field

[0001] The invention relates to the technical field of plate stamping, and in particular to a plate stamping device for a power distribution cabinet. Background Art

[0002] The power distribution cabinet is divided into power distribution cabinet, lighting distribution cabinet and metering cabinet. It is the final equipment of the power distribution system. The power distribution cabinet is a general term for the motor control center. The power distribution cabinet is used in substations, power plants, industrial and mining enterprises and other places for lighting, power distribution and control. Its box is generally square and adopts a plate structure, which needs to be processed by a stamping device.

[0003] The application document with the publication number CN117139489A discloses a non-destructive stamping processing equipment for the alloy sheet of the power distribution cabinet, which relates to the technical field of the preparation of the alloy sheet of the power distribution cabinet, in order to solve the problem that the middle position of the plate body is prone to sinking during stamping, which causes the folding positions on both sides to shift, and the plate body surface is prone to pulling damage during the stamping process. In addition, the stamped parts need to be removed from the mold after the stamping is completed. The application document includes: a base; an inverted L-shaped support vertical plate is fixedly installed vertically downward at the rear end edge of the base; a control box is fixedly installed on the back side wall of the support vertical plate; an upper mold is installed below the upper end of the support vertical plate. The application document can reduce the wear and damage to the aluminum alloy sheet of the power distribution cabinet, and cooperate with the upper mold to continue to move downward to stamp the aluminum alloy sheet of the power distribution cabinet into a concave structure, thereby improving the one-piece molding effect and reducing the pulling wear on the surface of the aluminum alloy sheet of the power distribution cabinet.

[0004] In the process of stamping the plates in the existing distribution cabinet plate stamping device, as the plates are continuously conveyed, the plates can be continuously stamped and bent into shape. There is no supporting mechanism to fix the plates in the bending process, so that the plates will shake, which may cause deformation at the bends. Moreover, after stamping and forming, the plates will be stamped into a square frame structure, and the stamping mechanism will be on the inside of the square frame. The frame needs to be broken open so that it can pass through the stamping mechanism. This method greatly reduces work efficiency. Summary of the invention

[0005] The present invention provides a plate punching device for a distribution cabinet, aiming to solve the problem in the related art that during the stamping process of the plate, the existing plate punching device for the distribution cabinet can continuously punch and bend the plate into shape as the plate is continuously conveyed, and there is no supporting mechanism to fix the plate in the bending process, so that the plate shakes, which may cause deformation at the bending part, and after stamping and forming, the plate will be punched into a square frame structure, and the stamping mechanism will be on the inner side of the square frame, and the frame needs to be pried open so as to pass through the stamping mechanism. This method greatly reduces the technical problem of working efficiency.

[0006] A stamping device for the sheet metal of a power distribution cabinet according to the present invention includes a feeding module, a conveying module, a cutting mechanism, and a stamping module. The stamping module includes a stamping unit, and the stamping unit includes a workbench, a stamping plate rotatably mounted on the workbench along an axis extending in the front-rear direction, and a driving member for driving the stamping plate to switch between a horizontal state and a vertical state; the stamping module further includes a pressing unit and a supporting unit; the pressing unit includes a pressing member horizontally movably mounted on the workbench in the front-rear direction and a power assembly for driving the pressing member to move, and the pressing member abuts against the sheet metal and is used to cooperate with the stamping plate to stamp and bend the sheet metal; the supporting unit includes a telescopic member rotatably mounted on the workbench along an axis extending in the front-rear direction, a bearing member rotatably mounted on the telescopic portion of the telescopic member along an axis extending in the front-rear direction, and four suction members circumferentially distributed on the bearing member, and the suction member located directly below the bearing member adsorbs on the sheet metal; the bearing member has two extreme movement positions on the left and right. When moving to the right extreme position, the stamping plate pushes the suction member and the bearing member to rotate 90 degrees clockwise around the bending point of the sheet metal to reach the right extreme position, completing one stamping of the sheet metal; when moving to the left extreme position, the conveying module conveys the sheet metal, and the sheet metal drives the suction member and the bearing member to horizontally slide to the left extreme position.

[0007] Beneficial effects: The bearing member has two extreme movement positions on the left and right. During stamping, the stamping plate pushes the suction member and the bearing member to rotate 90 degrees around the bending point of the sheet metal to reach the right extreme position. When the bearing member moves to the left extreme position, the sheet metal will be conveyed to the left at the same time. Since the suction member adsorbs on the sheet metal, the sheet metal will drive the bearing member to slide to the left when moving, until the bearing member is translated to the left extreme position. During each stamping process, the suction member will rotate 90 degrees synchronously with the stamped and bent sheet metal. There is a set of suction members corresponding to and supporting and fixing each stamped sheet metal surface, so the shaking during the stamping of the sheet metal is avoided, effectively ensuring the stability during the stamping process. At the same time, after stamping is completed, the sheet metal frame can be directly pulled out backward, and the suction members will all rotate, ensuring the smooth removal of the sheet metal, facilitating the unloading of the stamped sheet metal, and effectively saving manpower.

[0008] Preferably, four fixing rods are circumferentially distributed on the bearing member. An installation frame is fixedly installed at one end of each fixing rod away from the bearing member. A suction member is rotatably installed on the installation frame. The suction member is a cylindrical magnet. The suction member located in the vertical direction of the bearing member rotates along an axis extending in the left-right direction, and the suction member located in the horizontal direction of the suction member rotates along an axis extending in the vertical direction.

[0009] The effect is that: The suction member is a cylindrical magnet, which can not only adsorb on the sheet metal, but also facilitate the removal of the stamped workpiece.

[0010] Preferably, the fixing rod is a telescopic rod to be suitable for stamping workpieces of different sizes.

[0011] Its effect is that by controlling the length of the fixed rod, it can be applicable to workpieces of different sizes.

[0012] Preferably, the telescopic member includes a lower telescopic member and an upper telescopic member that are slidably engaged. The lower telescopic member rotates about an axis extending in the front-rear direction on the workbench. A telescopic cylinder is fixedly installed on the lower telescopic member, and the telescopic portion of the telescopic cylinder is fixedly connected to the upper telescopic member.

[0013] Its effect is that the telescoping between the lower telescopic member and the upper telescopic member, combined with the rotation of both in the left-right direction, can ensure that the bearing member reciprocates between two extreme positions on the left and right.

[0014] Preferably, the power assembly includes a gear rotatably installed on the workbench. The gear is driven by a motor, and the gear is meshed with the pressing member to drive the pressing member to move back and forth.

[0015] Preferably, the pressing member is a rectangular plate-like structure.

[0016] Preferably, the driving member is a stamping cylinder rotatably fitted about an axis extending in the front-rear direction on the workbench. The telescopic portion of the stamping cylinder is rotatably fitted with the stamping plate, and the telescopic portion of the stamping cylinder is rotatably connected to the stamping plate about an axis extending in the front-rear direction.

[0017] Preferably, the conveying module includes a conveying frame fixedly installed on the workbench. Two conveying rollers are rotatably installed inside the conveying frame. The two conveying rollers are arranged vertically at intervals, and both conveying rollers rotate about an axis extending in the front-rear direction to convey the sheet material.

[0018] Preferably, the feeding module includes a bracket fixedly installed on the ground. A winding roller is horizontally rotatably installed on the bracket.

[0019] Preferably, the adsorbing member is a suction cup structure.

[0020] Its effect is that the adsorbing member with a suction cup structure enables the device to be applicable to sheets without magnetism.

[0021] With the above technical solutions, the beneficial effects of the present invention are as follows: The carrier has two extreme movement positions on the left and right. In the left extreme position, the stamping plate is in a horizontal state, the carrier is located directly above the stamping plate, and the suction member directly below the carrier abuts against the plate on the upper surface of the stamping plate. During stamping, the stamping plate pushes the suction member and the carrier to rotate 90 degrees around the bending point of the plate to reach the right extreme position. When the carrier moves to the left extreme position, the plate will be conveyed to the left at the same time. Since the suction member adsorbs on the plate, the plate will drive the carrier to slide to the left when it moves until the carrier translates to the left extreme position. This cycle is repeated to complete the stamping and forming of the plate. During each stamping process, the suction member will rotate 90 degrees synchronously with the stamping and bent plate, and there is a set of suction members corresponding to and supporting and fixing each stamping-formed plate surface, so the shaking during the stamping of the plate is avoided, effectively ensuring the stability during the stamping process. At the same time, after the stamping is completed, the plate frame can be directly pulled out to the rear, and the suction members will all rotate to ensure the smooth removal of the plate, facilitating the unloading of the stamped plate and effectively saving manpower.

[0034] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present invention, but should not be construed as limiting the present invention.

[0035] As Figures 1 to 10 shown, a specific embodiment of a stamping device for sheets of a power distribution cabinet according to the present invention includes a feeding module, a flattening mechanism 20, a conveying module, and a stamping module.

[0036] The feeding module is used for uncoiling the sheet, the flattening mechanism 20 is used for flattening the sheet, the conveying module is close to the stamping module and is used for conveying the sheet, and finally the sheet reaches the stamping module for stamping and forming.

[0037] As Figure 1 shown, the feeding module includes a bracket 10 fixedly installed on the ground. A coiling roller 11 is horizontally rotatably installed on the bracket 10. The coiling roller 11 rotates around an axis extending in the front-rear direction, and a motor for driving the coiling roller 11 to rotate is installed on the bracket 10. A sheet coil 12 is installed on the coiling roller 11. When the coiling roller 11 rotates, the sheet coil 12 can be uncoiled, so as to provide a sheet for the stamping module for processing.

[0038] The flattening mechanism 20 is arranged on the left side of the bracket 10, that is, the flattening mechanism 20 is located in the uncoiling direction of the sheet coil 12. The sheet released from the sheet coil 12 passes through the flattening mechanism 20, and the flattening mechanism 20 can flatten the sheet. Since the sheet raw material is in a coiled state, the sheet released from the sheet coil 12 is also bent. After the flattening mechanism 20 flattens the sheet, the quality of stamping and forming can be guaranteed. The structure and working principle of the flattening mechanism 20 both belong to the prior art and will not be elaborated here.

[0039] As Figure 1 And Figure 2As shown, the conveying module includes a conveying frame 30 and conveying rollers 31. Two conveying rollers 31 are rotatably installed inside the conveying frame 30, and the two conveying rollers 31 are arranged vertically at intervals. Both of the two conveying rollers 31 rotate about an axis extending in the front-rear direction, and the conveying rollers 31 are driven by a motor. The sheet material that has been flattened by the flattening mechanism 20 will pass between the two conveying rollers 31. Thus, when the two conveying rollers 31 rotate, the sheet material can be conveyed to the left, that is, the sheet material is conveyed to the stamping module for stamping and forming. In this embodiment, the conveying rollers 31 can be made of rubber or metal. It should be specifically noted that in this embodiment, the conveying module is installed on the workbench 40 mentioned below. The conveying module belongs to the prior art and will not be elaborated here.

[0040] The stamping module includes a stamping unit, a pressing unit, and a supporting unit.

[0041] The pressing unit is used to tightly fix the bending point of the sheet material, and the supporting unit is used to support and fix the sheet material during stamping to prevent the sheet material from shaking. The stamping unit is used to continuously stamp and form the sheet material.

[0042] As Figure 2 And Figure 5 As shown, the stamping unit includes a workbench 40, a stamping cylinder 41, a stamping plate 42, a rotating shaft 43, a rear rotating seat 44, a front rotating seat 45, and a conveying table 46.

[0043] An installation cavity that is recessed downward is formed on the left side of the workbench 40, and both the left side and the upper side of the installation cavity are of an open structure. A stamping cylinder 41 is rotatably installed near the bottom of the installation cavity. The bottom of the stamping cylinder 41 is rotationally fitted in the installation cavity along an axis extending in the front-rear direction, that is, the bottom of the stamping cylinder 41 is rotationally fitted with the front and rear side walls of the installation cavity.

[0044] A stamping plate 42 is rotatably installed at the telescopic part of the stamping cylinder 41, and the telescopic part of the stamping cylinder 41 is rotationally fitted with the bottom surface (the side facing away from stamping) of the stamping plate 42 along an axis extending in the front-rear direction. Rotating shafts 43 are fixedly installed at positions near the front and rear sides of the hinged end (right end) of the stamping plate 42. The front and rear two rotating shafts 43 are coaxially arranged and the rotating shafts 43 rotate about an axis extending in the front-rear direction.

[0045] A conveying table 46 is fixedly installed on the upper surface of the workbench 40. The conveying table 46 is in a rectangular structure, and its length direction is parallel to the left-right direction. The front and rear positions on the left side of the conveying table 46 are respectively provided with a front rotating seat 45 and a rear rotating seat 44. The front rotating seat 45 is fixedly installed at a position near the left end on the front side of the conveying table 46, and the rear rotating seat 44 is fixedly installed at a position near the left end on the rear side of the conveying table 46. The front rotating seat 45 and the rear rotating seat 44 are coaxially arranged.

[0046] In this embodiment, the front turntable 45 has a circular structure, and the rear turntable 44 has a semi-circular structure. The two front and rear rotating shafts 43 are respectively rotatably installed on the front turntable 45 and the rear turntable 44, and the rotating shafts 43 are coaxially arranged with both the front turntable 45 and the rear turntable 44.

[0047] The stamping plate 42 has horizontal and vertical states. In the horizontal state, the stamping cylinder 41 is in a contracted state, and the upper surface (stamping surface) of the stamping plate 42 is flush with the upper surface of the conveying table 46. When the stamping plate 42 rotates from the horizontal state to the vertical state, the stamping cylinder 41 extends, thereby pushing the stamping plate 42 to rotate clockwise around the axis of the rotating shaft 43. When the stamping plate 42 rotates to the vertical state, the stamping plate 42 is perpendicular to the conveying table 46.

[0048] When the sheet is conveyed onto the stamping plate 42, the pressing unit can press on the position of the sheet near the bending point. Then the stamping cylinder 41 extends, pushing the stamping plate 42 to rotate clockwise around the axis of the rotating shaft 43 until the stamping plate 42 rotates to the vertical state. At this time, the sheet located on the stamping plate 42 will be pushed and bent by the stamping plate 42, and the sheet will also be bent into a 90-degree state around the bending point, completing the stamping and bending forming of the sheet.

[0049] As Figure 6 shown, the pressing unit includes a mounting seat 50, a gear 51, and a pressing member 52.

[0050] The mounting seat 50 is fixedly installed on the upper surface of the workbench 40, and the mounting seat 50 is located on the front side of the front turntable 45. A pressing member 52 is horizontally slidably installed on the mounting seat 50 in the front-rear direction. In this embodiment, the pressing member 52 has a rectangular plate-like structure, and the length direction of the pressing member 52 is parallel to the front-rear direction.

[0051] The front turntable 45 has an avoidance hole that penetrates through the front and rear. The moving end of the pressing member 52 passes through the avoidance hole on the front turntable 45 and extends above the conveying table 46.

[0052] A rack is fixedly installed on the left side surface of the pressing member 52. A gear 51 meshing with the rack is rotatably installed on the workbench 40. A motor (not shown in the figure) for driving the gear 51 to rotate is installed on the workbench 40. Thus, by driving the gear 51 to rotate through the motor, the gear 51 drives the pressing member 52 to slide back and forth.

[0053] There is a certain gap between the lower surface of the pressing member 52 and the upper surface of the conveying table 46, and the size of this gap is the thickness of the sheet. Thus, when the pressing member 52 moves to the rear side, the pressing member 52 will abut against the upper surface of the sheet, and can play a pressing role on the sheet, ensuring the stamping of the sheet when the stamping plate 42 rotates, and avoiding the situation where the sheet warps when the stamping plate 42 pushes the sheet.

[0054] It should be particularly emphasized that when the stamping plate 42 rotates to a vertical state, there is also a certain gap between the stamping surface of the stamping plate 42 and the left side surface of the pressing member 52, and the size of this gap is the thickness of the plate. When the stamping plate 42 rotates to bend the plate by 90 degrees, the part of the plate in the vertical direction will be located between the stamping surface of the stamping plate 42 and the left side surface of the pressing member 52, and this gap is to accommodate the plate. That is, the length side on the left of the lower surface of the pressing member 52 is the bending point of the plate.

[0055] When stamping the plate, the motor drives the gear 51 to rotate, so that the gear 51 drives the pressing member 52 to slide backward, and finally the pressing member 52 moves above the plate. The pressing member 52 just presses tightly on the bending point of the plate, and then the stamping cylinder 41 extends, pushing the stamping plate 42 to rotate clockwise around the axis of the rotating shaft 43 until the stamping plate 42 rotates to a vertical state. At this time, the plate located on the stamping plate 42 will be pushed and bent by the stamping plate 42, and the plate will also be bent by 90 degrees around the bending point, completing the stamping and bending forming of the plate.

[0056] It should be particularly noted that the purpose of the pressing member 52 sliding in the front-rear direction is to avoid the left-right movement of the support unit. When the support unit needs to move left and right through the pressing member 52, the pressing member 52 will move backward to ensure the passage of the support unit, which will be explained in detail later.

[0057] In this embodiment, the pressing member 52 uses the method of sliding back and forth to avoid the support unit. In other embodiments, the avoidance method of the pressing member 52 is not limited to this, and it can also be achieved by the horizontal rotation of the pressing member 52.

[0058] In addition, the gap between the bottom of the pressing member 52 and the upper surface of the conveying table 46 is fixed. According to the different thicknesses of the plates, pressing members 52 with different heights can also be replaced to adapt to plates with different thicknesses.

[0059] As Figure 3 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 8 and Figure 9 shown, the support unit includes a lower telescopic member 60, an upper telescopic member 61, a telescopic cylinder 62, a bearing member 63, a fixed rod 64, a mounting bracket 65 and a suction member 66.

[0060] The lower telescopic member 60 is rotatably mounted on the front rotating seat 45, and the lower telescopic member 60 rotates along the axis extending in the front-rear direction. The upper telescopic member 61 is slidably mounted on the lower telescopic member 60, and the telescopic cylinder 62 is also fixedly mounted on the lower telescopic member 60. The telescopic part of the telescopic cylinder 62 is fixedly connected to the upper telescopic member 61, so that when the telescopic cylinder 62 expands and contracts, it can drive the upper telescopic member 61 to slide on the lower telescopic member 60.

[0061] A bearing member 63 is horizontally rotatably mounted on the upper telescopic member 61, and the bearing member 63 can rotate about an axis extending in the front-rear direction. In this embodiment, the bearing member 63 has a square structure. The bearing member 63 is located above the conveying table 46 and corresponds to the plate in the up-down direction.

[0062] Support assemblies are provided on the upper, lower, left, and right four surfaces of the bearing member 63. Each support assembly includes two fixing rods 64 horizontally and fixedly mounted on the bearing member 63 in the front-rear direction. An installation frame 65 is fixedly mounted at one end of the fixing rod 64 away from the bearing member 63, and a suction member 66 is rotatably mounted on the installation frame 65. In this embodiment, the suction member 66 is a cylindrical magnet. The suction members 66 on the opposite two surfaces of the bearing member 63 are horizontally arranged, and the suction members 66 on the upper and lower surfaces are perpendicularly arranged with the suction members 66 on the left and right surfaces.

[0063] The suction members 66 on the upper and lower surfaces of the bearing member 63 rotate about an axis extending in the left-right direction, and the suction members 66 on the left and right surfaces of the suction member 66 rotate about an axis extending in the vertical direction.

[0064] In this embodiment, the workpiece formed by stamping the plate has a square structure, so the lengths of the fixing rods 64 in the up-down, left-right four directions are the same.

[0065] The bearing member 63 has two extreme movement positions on the left and right. In the left extreme position, the stamping plate 42 is in a horizontal state, the bearing member 63 is located directly above the stamping plate 42, and the suction member 66 directly below the bearing member 63 abuts against the plate on the upper surface of the stamping plate 42. When the stamping plate 42 stamps, it will push the suction member 66 and the bearing member 63 to rotate 90 degrees around the bending point of the plate to reach the right extreme position. The lower telescopic member 60 and the upper telescopic member 61 will rotate around the axis of the front rotating seat 45 following the bearing member 63. The movement trajectory of the bearing member 63 is an arc, so relative sliding will occur during the rotation of the lower telescopic member 60 and the upper telescopic member 61, that is, by the telescopic cylinder 62 telescoping, the upper telescopic member 61 can be driven to slide on the lower telescopic member 60. Then the stamping plate 42 returns to the horizontal state. When the bearing member 63 moves to the left extreme position, the plate will be conveyed to the left at the same time. Since the suction member 66 adsorbs on the plate, the plate will drive the bearing member 63 to slide to the left when moving, and at the same time, the lower telescopic member 60 and the upper telescopic member 61 will also perform adaptive telescoping until the bearing member 63 is translated to the left extreme position.

[0066] During operation, the plate is first conveyed to the upper surface of the stamping plate 42 to the left. At this time, the bearing member 63 is located at the left extreme position (as Figure 7As shown in the figure, the suction attachment 66 directly below the carrier 63 abuts against the plate on the upper surface of the stamping plate 42, and the suction attachment 66 is located at the center position in the left-right direction of the plate bending surface. The stamping plate 42 rotates to push the plate for bending. During the rotation of the stamping plate 42, it will simultaneously push the suction attachment 66 (abutting against the plate) directly below it. The suction attachment 66 and the carrier 63 rotate 90 degrees around the bending point of the plate to reach the right extreme position (as Figure 8 shown in the figure). That is to say, the suction attachment 66 abutting on the bending surface will rotate 90 degrees synchronously with the stamping and bending plate. Generally speaking, the suction attachment 66 originally directly below the carrier 63 will rotate 90 degrees clockwise to be in the left position of the carrier 63. Similarly, the suction attachments 66 in the four directions of the carrier 63 will all rotate 90 degrees clockwise. When the suction attachment 66 originally on the right side of the carrier 63 reaches the right extreme position, it will be directly below the carrier 63 and abut against the upper surface of the plate. At this time, the first stamping of the plate is completed, and the first surface of the workpiece is formed.

[0067] Immediately afterwards, the motor is driven to rotate the gear 51, so that the gear 51 drives the pressing member 52 to slide forward, avoiding interference with the movement of the suction attachment 66. Then the plate continues to be conveyed to the upper surface of the stamping plate 42 again. Since the suction attachment 66 adsorbs on the plate, when the plate is conveyed to the left, it will drive the suction attachment 66 to move to the left together, that is, give the carrier 63 a force to move horizontally to the left, so that the carrier 63 slides horizontally to the left extreme position (i.e., Figures 8 to 9 the state shown in the figure). At the same time, relative sliding will occur during the rotation of the lower telescopic member 60 and the upper telescopic member 61. In cooperation with the horizontal movement of the carrier 63, when the two telescopic members rotate from the inclined state at the right extreme position to the vertical state, the telescopic cylinder 62 drives the upper telescopic member 61 to perform a contraction movement. When rotating from the vertical state to the left extreme position, the telescopic cylinder 62 drives the upper telescopic member 61 to perform an elongation movement. Then this cycle continues until the plate is stamped three times. At this time, the stamped plate will form a square frame structure (as Figure 10 ) That is to say, the end of the original plate will abut against the plate on the conveying table 46 after being stamped and bent. During each stamping process, the suction attachment 66 will rotate 90 degrees synchronously with the stamping and bending plate. There is a set of suction attachments 66 corresponding to and supporting and fixing each stamping-formed plate surface, so the shaking of the plate during the stamping process is avoided, effectively ensuring the stability during the stamping process.

[0068] In addition, a cutting mechanism (not shown in the figure) is also provided on the workbench 40. This cutting mechanism is a prior art and belongs to the conventional structure of the stamping device, so it is not shown in the figure. Then the cutting mechanism cuts the sheet material, and the cut sheet material is the square frame formed by stamping. Then the stamped frame can be directly pulled backward. Since the suction attachments 66 on the upper and lower surfaces of the carrier 63 rotate about the axis extending in the left-right direction, and the suction attachments 66 on the left and right surfaces of the suction attachments 66 rotate about the axis extending in the vertical direction, when the sheet material frame is pulled backward, the suction attachments 66 will all rotate to ensure the smooth removal of the sheet material. It is convenient to unload the stamped sheet material, effectively saving manpower.

[0069] In other embodiments, the fixing rod 64 is replaceable and can be replaced with different lengths, or the fixing rod 64 has a telescopic structure. For example, the fixing rod 64 can be a telescopic rod, so as to be applicable to square frames of different sizes.

[0070] In addition, for sheet materials that do not have magnetic materials, the suction attachments 66 can also be a suction cup structure. A mechanism for controlling the suction force of the magnetic disk is installed on the carrier 63. The principle is the same as above, and the stamping of this kind of material can still be achieved.

[0071] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
