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] The present invention discloses a plate punching device for a power distribution cabinet, comprising: a material discharge module, a conveying module, a cutting mechanism and a punching module, wherein the punching module comprises a punching unit, and the punching unit comprises a workbench, a punching plate rotating on the workbench along an axis extending in a front-to-back direction, and a driving member driving the punching plate to switch between horizontal and vertical states; the punching module also comprises a pressing unit and a supporting unit; the pressing unit comprises a pressing member installed on the workbench for horizontal movement back and forth and a power assembly for driving the pressing member to move, the pressing member abuts against the plate and is used to cooperate with the punching plate to punch and bend the plate; the supporting unit comprises a pressing member for horizontal movement back and forth and a power assembly for driving the pressing member to move; ... It includes a telescopic part that rotates on the workbench along an axis extending in the front-to-back direction, a bearing part that rotates on the telescopic part of the telescopic part along an axis extending in the front-to-back direction, and four adsorption parts that are evenly distributed on the bearing part in the circumferential direction. The adsorption part located directly below the bearing part is adsorbed on the plate; the bearing part has two extreme movement positions on the left and right. When moving to the right extreme position, the stamping plate pushes the adsorption part and the bearing part turns 90 degrees clockwise around the bending point of the plate to reach the right extreme position, completing a stamping of the plate; when moving to the left extreme position, the conveying module conveys the plate, and the plate drives the adsorption part and the bearing part to slide horizontally to the left extreme position.

[0007] Beneficial effects: The support has two extreme movement positions on the left and right. During stamping, the stamping plate pushes the adsorption part and the support turns 90 degrees around the bending point of the plate to reach the right extreme position. When the support moves to the left extreme position, the plate will be transported to the left at the same time. Since the adsorption part is adsorbed on the plate, the plate will drive the support to slide to the left when it moves, until the support moves to the left to the left extreme position. During each stamping process, the adsorption part will rotate 90 degrees synchronously with the stamped and bent plate. Each stamped plate surface has a corresponding set of adsorption parts to support and fix it, so the shaking of the plate during the stamping process is avoided, and the stability of the stamping process is effectively guaranteed. At the same time, after the stamping is completed, the plate frame can be directly pulled out to the rear side, and the adsorption parts will rotate to ensure the smooth removal of the plate, which is convenient for unloading the stamped plate and effectively saves manpower.

[0008] Preferably, the support member is evenly distributed with four fixing rods along its circumference, and a mounting frame is fixedly installed on one end of each fixing rod away from the support member, and an adsorption member is rotatably installed on the mounting frame. The adsorption member is a cylindrical magnet, and the adsorption member located in the vertical direction of the support member rotates along the axis extending in the left and right direction, and the adsorption member located in the horizontal direction of the adsorption member rotates along the axis extending in the vertical direction.

[0009] The effect is that the adsorption piece is a cylindrical magnet, which can not only be adsorbed on the plate, but also facilitates the removal of the stamped workpiece.

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

[0011] The effect is that by controlling the length of the fixing rod, it can be suitable for workpieces of different sizes.

[0012] Preferably, the telescopic member includes a lower telescopic member and an upper telescopic member that are slidably matched, the lower telescopic member rotates on the workbench along an axis extending in the front-rear direction, a telescopic cylinder is fixedly mounted on the lower telescopic member, and the telescopic part of the telescopic cylinder is fixedly connected to the upper telescopic member.

[0013] The effect is that the extension and retraction of the lower telescopic member and the upper telescopic member are coordinated with the rotation of the two in the left and right directions, so that the bearing member can be reciprocated between the left and right extreme positions.

[0014] Preferably, the power assembly includes a gear rotatably mounted on the workbench, the gear is driven by a motor, and the gear is meshedly connected with the pressing member so that the gear drives the pressing member to move forward and backward.

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

[0016] Preferably, the driving member is a stamping cylinder on the workbench that is rotatably matched with the axis extending in the front-to-back direction, the telescopic part of the stamping cylinder is rotatably matched with the stamping plate, and the telescopic part of the stamping cylinder is rotatably connected with the axis extending in the front-to-back direction of the stamping plate.

[0017] Preferably, the conveying module includes a conveying frame fixedly mounted on the workbench, and two conveying rollers are rotatably mounted inside the conveying frame. The two conveying rollers are vertically spaced apart, and both conveying rollers rotate along an axis extending in the front-rear direction to convey the plate.

[0018] Preferably, the unloading module comprises a bracket fixedly mounted on the ground, and a roller is horizontally rotatably mounted on the bracket.

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

[0020] The effect is that the adsorption member of the suction cup structure can make the device suitable for plates that are not magnetic.

[0021] By adopting the above technical scheme, the beneficial effects of the present invention are as follows: the bearing member has two extreme movement positions on the left and right. When in the left extreme position, the stamping plate is in a horizontal state, the bearing member is located directly above the stamping plate, and the adsorption member directly below the bearing member abuts against the plate on the upper surface of the stamping plate. During stamping, the stamping plate pushes the adsorption member and the bearing member flips 90 degrees around the bending point of the plate to reach the right extreme position. When the bearing member moves to the left extreme position, the plate will be transported to the left at the same time. Since the adsorption member is adsorbed on the plate, the plate will drive the bearing member to slide to the left when it moves, until the bearing member translates to the left to the left extreme position, and the stamping forming of the plate is completed in this cycle. During each stamping process, the adsorption member will rotate 90 degrees synchronously with the stamped and bent plate. Each stamped plate surface has a corresponding set of adsorption members to support and fix it, so the shaking of the plate during the stamping process is avoided, and the stability of the stamping process is effectively guaranteed. At the same time, after the stamping is completed, the sheet frame can be directly pulled out to the rear side, and the adsorption parts will rotate to ensure the smooth removal of the sheet, which is convenient for unloading the stamped sheet and effectively saves manpower.

[0033] 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.

[0034] like Figures 1 to 10 As shown, a specific embodiment of a punching device for a plate of a power distribution cabinet of the present invention comprises a material discharge module, a flattening mechanism 20, a conveying module and a punching module.

[0035] The unwinding module is used to unwind the sheet material, the flattening mechanism 20 is used to flatten the sheet material, the conveying module is close to the stamping module and is used to convey the sheet material, and the sheet material finally reaches the stamping module for stamping and forming.

[0036] like Figure 1 As shown, the unloading module includes a bracket 10 fixedly mounted on the ground, a roller 11 is horizontally mounted on the bracket 10, the roller 11 rotates around an axis extending in the front-rear direction, and a motor is mounted on the bracket 10 to drive the roller 11 to rotate. A sheet roll 12 is mounted on the roller 11, and when the roller 11 rotates, the sheet roll 12 can be unwound, thereby providing the stamping module with sheets for processing.

[0037] The flattening mechanism 20 is arranged on the left side of the bracket 10, that is, the flattening mechanism 20 is located in the unwinding direction of the sheet roll 12. The sheet released from the sheet roll 12 passes through the flattening mechanism 20, and the flattening mechanism 20 can flatten the sheet. Since the sheet raw material is in a rolled state, the sheet released from the sheet roll 12 is also curved. After the flattening mechanism 20 flattens the sheet, the quality of stamping can be guaranteed. The structure and working principle of the flattening mechanism 20 belong to the prior art and will not be described in detail here.

[0038] like Figure 1 and Figure 2As shown, the conveying module includes a conveying frame 30 and a conveying roller 31. Two conveying rollers 31 are rotatably installed inside the conveying frame 30, and the two conveying rollers 31 are arranged vertically at intervals. The two conveying rollers 31 rotate along an axis extending in the front-to-back direction, and the conveying rollers 31 are driven by a motor. The plate that has been flattened by the flattening mechanism 20 will pass between the two conveying rollers 31, so that when the two conveying rollers 31 rotate, the plate can be conveyed to the left side, that is, the plate is conveyed to the stamping module for stamping and forming. In this embodiment, the conveying roller 31 can be made of rubber or metal. It should be 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 described in detail here.

[0039] The punching module includes a punching unit, a pressing unit and a supporting unit.

[0040] The pressing unit is used to press and fix the bending points of the plate, the supporting unit is used to support and fix the plate during the stamping process to prevent the plate from shaking, and the stamping unit is used to continuously stamp the plate into shape.

[0041] like 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 .

[0042] A downwardly recessed installation cavity is provided on the left side of the workbench 40, and the left side and the top of the installation cavity are both open structures. A punching cylinder 41 is rotatably installed near the bottom of the installation cavity, and the bottom of the punching cylinder 41 is rotatably matched with the installation cavity along the axis extending in the front-to-back direction, that is, the bottom of the punching cylinder 41 is rotatably matched with the front and rear side walls of the installation cavity.

[0043] The telescopic part of the punching cylinder 41 is rotatably mounted with a punching plate 42, and the telescopic part of the punching cylinder 41 is rotatably matched with the bottom surface (the side away from the punching) of the punching plate 42 along the axis extending in the front-to-back direction. A rotating shaft 43 is fixedly mounted at the hinged end (right end) of the punching plate 42 near the front and rear sides, and the front and rear rotating shafts 43 are coaxially arranged and rotate along the axis extending in the front-to-back direction.

[0044] A conveyor 46 is fixedly mounted on the upper surface of the workbench 40. The conveyor 46 is in a rectangular structure, and its length direction is parallel to the left-right direction. A front swivel seat 45 and a rear swivel seat 44 are respectively arranged at the front and rear positions of the left side of the conveyor 46. The front swivel seat 45 is fixedly mounted at a position near the left end of the front side of the conveyor 46, and the rear swivel seat 44 is fixedly mounted at a position near the left end of the rear side of the conveyor 46, and the front swivel seat 45 and the rear swivel seat 44 are coaxially arranged.

[0045] In this embodiment, the front rotating seat 45 is a circular structure, the rear rotating seat 44 is a semicircular structure, and the front and rear rotating shafts 43 are rotatably installed on the front rotating seat 45 and the rear rotating seat 44 respectively, and the rotating shafts 43 are coaxially arranged with the front rotating seat 45 and the rear rotating seat 44.

[0046] The stamping plate 42 has a horizontal state and a vertical state. In the horizontal state, the stamping cylinder 41 is in a retracted state, and the upper surface (stamping surface) of the stamping plate 42 is flush with the upper surface of the conveying platform 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 in a clockwise direction around the axis of the rotating shaft 43. When the stamping plate 42 rotates to the vertical state, the stamping plate 42 and the conveying platform 46 are perpendicular to each other.

[0047] When the sheet is conveyed onto the stamping plate 42, the pressing unit can press the position of the sheet close to the bending point, and then the stamping cylinder 41 extends, pushing the stamping plate 42 to rotate in a clockwise direction around the axis of the rotating shaft 43 until the stamping plate 42 rotates to a vertical state. At this time, the sheet on the stamping plate 42 will be pushed and bent by the stamping plate 42, and the sheet will also be bent to a 90-degree state around the bending point, completing the stamping and bending of the sheet.

[0048] like Figure 6 As shown, the pressing unit includes a mounting seat 50 , a gear 51 and a pressing member 52 .

[0049] The mounting seat 50 is fixedly mounted on the upper surface of the workbench 40, and the mounting seat 50 is located in front of the front rotating seat 45. A pressing member 52 is horizontally slidably mounted on the mounting seat 50 along the front-to-back direction. In this embodiment, the pressing member 52 is a rectangular plate-shaped structure, and the length direction of the pressing member 52 is parallel to the front-to-back direction.

[0050] The front rotating seat 45 has an escape hole extending from front to back, and the moving end of the pressing member 52 passes through the escape hole on the front rotating seat 45 and extends to above the conveying platform 46 .

[0051] A rack is fixedly installed on the left side surface of the pressing member 52, and 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, so that the motor drives the gear 51 to rotate, so that the gear 51 drives the pressing member 52 to slide forward and backward.

[0052] There is a certain gap between the lower surface of the pressing member 52 and the upper surface of the conveying platform 46, and the size of the gap is the thickness of the plate. Therefore, when the pressing member 52 moves to the rear side, the pressing member 52 will abut against the upper surface of the plate, and can press the plate to ensure the stamping of the plate when the stamping plate 42 rotates, and avoid the plate from warping up when the stamping plate 42 pushes the plate.

[0053] It is particularly emphasized that when the stamping plate 42 is rotated to a vertical state, there is also a certain gap between the stamping surface of the stamping plate 42 and the left side of the pressing member 52. The size of the gap is the thickness of the plate. When the stamping plate 42 is rotated to bend the plate at 90 degrees, the part of the plate in the vertical direction will be between the stamping surface of the stamping plate 42 and the left side of the pressing member 52. The gap is to accommodate the plate. That is, the length side of the lower surface of the pressing member 52 on the left side is the bending point of the plate.

[0054] When stamping the sheet, the motor drives the gear 51 to rotate, so that the gear 51 drives the pressing piece 52 to slide backward, and finally moves the pressing piece 52 to the top of the sheet. The pressing piece 52 is just pressed against the bending point of the sheet, and then the stamping cylinder 41 extends, pushing the stamping plate 42 to rotate in a clockwise direction around the axis of the rotating shaft 43 until the stamping plate 42 rotates to a vertical state. At this time, the sheet on the stamping plate 42 will be pushed and bent by the stamping plate 42, and the sheet will also be bent 90 degrees around the bending point, completing the stamping and bending of the sheet.

[0055] It is particularly noted that the purpose of the pressing member 52 sliding in the front-to-back direction is to avoid the left-right movement of the support unit. When the support unit moves left-to-right and needs to pass through the pressing member 52, the pressing member 52 will move backward to ensure the passage of the support unit. This will be explained in detail later.

[0056] In this embodiment, the pressing member 52 avoids the support unit by sliding forward and backward. In other embodiments, the avoiding method of the pressing member 52 is not limited to this, and can also be achieved by horizontal rotation of the pressing member 52.

[0057] In addition, the gap between the bottom of the pressing member 52 and the upper surface of the conveying platform 46 is fixed. According to the thickness of the plate, the pressing members 52 of different heights can be replaced to adapt to plates of different thicknesses.

[0058] like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 as well as Fig. 9 As shown, the supporting unit includes a lower telescopic member 60 , an upper telescopic member 61 , a telescopic cylinder 62 , a bearing member 63 , a fixing rod 64 , a mounting frame 65 and a suction member 66 .

[0059] 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 forward and backward. The upper telescopic member 61 is slidably mounted on the lower telescopic member 60, and a telescopic cylinder 62 is fixedly mounted on the lower telescopic member 60, and the telescopic part of the telescopic cylinder 62 is fixedly connected to the upper telescopic member 61, so that when the telescopic cylinder 62 is extended and retracted, the upper telescopic member 61 can be driven to slide on the lower telescopic member 60.

[0060] A bearing member 63 is horizontally rotatably mounted on the upper telescopic member 61, and the bearing member 63 can rotate along an axis extending in the front-rear direction. In this embodiment, the bearing member 63 is a square structure. The bearing member 63 is located above the conveying platform 46 and corresponds to the plate up and down.

[0061] Support components are arranged on the four surfaces of the upper, lower, left and right of the bearing member 63. Each support component includes two fixing rods 64 fixedly mounted on the bearing member 63 horizontally in the front and rear directions. A mounting frame 65 is fixedly mounted on one end of the fixing rod 64 away from the bearing member 63. An adsorbing member 66 is rotatably mounted on the mounting frame 65. In this embodiment, the adsorbing member 66 is a cylindrical magnet. The adsorbing members 66 on the two opposite surfaces of the bearing member 63 are arranged horizontally with each other, and the adsorbing members 66 on the upper and lower surfaces and the adsorbing members 66 on the left and right surfaces are arranged vertically with each other.

[0062] The adsorption members 66 located on the upper and lower surfaces of the carrier 63 rotate along the axis extending in the left-right direction, and the adsorption members 66 located on the left and right surfaces of the adsorption member 66 rotate along the axis extending in the vertical direction.

[0063] In this embodiment, the workpiece formed by stamping a plate has a square structure, so the lengths of the fixing rods 64 in the four directions of up, down, left, and right are the same.

[0064] The supporting member 63 has two extreme movement positions on the left and right. When in the left extreme position, the stamping plate 42 is in a horizontal state, the supporting member 63 is located directly above the stamping plate 42, and the adsorption member 66 directly below the supporting member 63 abuts against the plate on the upper surface of the stamping plate 42. When the stamping plate 42 is stamped, it will push the adsorption member 66 and the supporting member 63 to flip 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 follow the supporting member 63 to rotate around the axis of the front rotating seat 45. The movement trajectory of the supporting member 63 is arc-shaped, so the lower telescopic member 60 and the upper telescopic member 61 will slide relative to each other during the rotation process, that is, the telescopic cylinder 62 is extended and retracted to drive the upper telescopic member 61 to slide on the lower telescopic member 60. Then the stamping plate 42 is reset to a horizontal state. When the supporting member 63 moves to the left extreme position, the plate will be transported to the left at the same time. Since the adsorption member 66 is adsorbed on the plate, the plate will drive the supporting member 63 to slide to the left when it moves. At the same time, the lower telescopic member 60 and the upper telescopic member 61 will also be adaptively extended and retracted until the supporting member 63 is translated to the left to the left extreme position.

[0065] During operation, the plate is first conveyed to the left to the upper surface of the stamping plate 42. At this time, the bearing member 63 is located at the left extreme position (such as Figure 7As shown in the figure, the adsorption member 66 directly below the bearing member 63 abuts against the plate on the upper surface of the stamping plate 42, and the adsorption member 66 is located at the center of the left and right directions of the bending surface of the plate. The stamping plate 42 rotates to push the plate to bend. During the rotation of the stamping plate 42, the adsorption member 66 directly below (abutting against the plate) will be pushed at the same time. The adsorption member 66 and the bearing member 63 are turned 90 degrees around the bending point of the plate to reach the right limit position (as shown in the figure). Figure 8 As shown in the figure, that is, the adsorption member 66 abutting against the bending surface will rotate 90 degrees synchronously with the plate being stamped and bent. In layman's terms, the adsorption member 66 originally located directly below the support member 63 will rotate 90 degrees clockwise to the left side of the support member 63. Similarly, the adsorption members 66 on the four directions of the support member 63 will all rotate 90 degrees in the clockwise direction. When the adsorption member 66 originally located on the right side of the support member 63 reaches the right limit position, it will be directly below the support member 63 and abut against the upper surface of the plate. At this time, the first stamping of the plate has been completed, and the first surface of the workpiece has been formed.

[0066] Then, the motor drives the gear 51 to rotate, so that the gear 51 drives the pressing member 52 to slide forward to avoid interfering with the movement of the adsorbing member 66. Then, the sheet continues to be transported to the left and reaches the upper surface of the stamping plate 42 again. Since the adsorbing member 66 is adsorbed on the sheet, when the sheet is transported to the left, it will drive the adsorbing member 66 to move to the left together, that is, it gives the bearing member 63 a horizontal force to move to the left, so that the bearing member 63 slides horizontally to the left to the left limit position (i.e. Figures 8 to 9 At the same time, the lower telescopic member 60 and the upper telescopic member 61 will slide relative to each other during the rotation process, and cooperate with the horizontal movement of the bearing member 63. During the process of the two telescopic members rotating from the inclined state of the right extreme position to the left to the vertical state, the telescopic cylinder 62 drives the upper telescopic member 61 to contract. During the process of rotating from the vertical state to the left to the left extreme position, the telescopic cylinder 62 drives the upper telescopic member 61 to extend. Then the cycle is repeated until the sheet is stamped three times. At this time, the stamped sheet will form a square frame structure (as shown in FIG. Fig.10 ), that is, after the end of the original sheet is stamped and bent, it will abut against the sheet on the conveyor 46. During each stamping process, the adsorbent 66 will rotate 90 degrees synchronously with the stamped and bent sheet. Each stamped sheet surface has a corresponding set of adsorbents 66 to support and fix it, so the shaking of the sheet during the stamping process is avoided, and the stability of the stamping process is effectively guaranteed.

[0067] In addition, a cutting mechanism (not shown in the figure) is also provided on the workbench 40. The cutting mechanism is a prior art and belongs to a conventional structure on the stamping device, so it is not shown in the figure. Then the cutting mechanism cuts the plate, and the cut plate is the square frame formed by stamping, and then the stamped frame can be directly pulled out to the rear side. Because the adsorption parts 66 on the upper and lower surfaces of the carrier 63 rotate along the axis extending in the left and right directions, and the adsorption parts 66 on the left and right surfaces of the adsorption parts 66 rotate along the axis extending in the vertical direction, when the plate frame is pulled out to the rear side, the adsorption parts 66 will rotate to ensure the smooth removal of the plate. The unloading of the stamped plate is convenient, which effectively saves manpower.

[0068] In other embodiments, the fixing rod 64 is replaceable and can be replaced with different lengths, or the fixing rod 64 is a telescopic structure, for example, the fixing rod 64 can be a telescopic rod, so that it can be suitable for square frames of different sizes.

[0069] In addition, for plates that are not made of magnetic material, the adsorption member 66 can also be a suction cup structure, and a mechanism for controlling the magnetic disk suction force is installed on the carrier 63. The same principle as above can still achieve stamping of plates of this material.

[0070] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
