Description

Technical Field

[0001] The present invention relates to the technical field of cobalt plate processing, and particularly relates to a numerical control cobalt plate shearing device. Background Art

[0002] Cobalt plates are plates made of metallic cobalt (Co) or cobalt-based alloys. Due to their unique physical and chemical properties, such as high melting point, corrosion resistance, high-temperature stability, magnetism, etc., cobalt plates play an irreplaceable role in multiple industrial fields. In order to meet the requirements of downstream products, for example, battery electrode sheets need to be cut into specific lengths and widths, so cobalt plates need to be sheared.

[0003] Existing cobalt plate shearing and processing equipment generally includes a conveying mechanism and a shearing member. First, the whole cobalt plate is conveyed to the position where the shearing member is located by the conveying mechanism, and then the shearing member is driven by a driving element to run and cut the cobalt plate into strip-shaped bodies. For the requirements of some specific products, it is also necessary to further cut the cobalt plate strip-shaped bodies into multiple block-shaped bodies. Therefore, it is necessary to transfer the strip-shaped cobalt plates to subsequent cutting equipment for further shearing.

[0004] The deficiencies of existing cobalt plate shearing and processing are as follows: Although existing cobalt plate shearing equipment can shear cobalt plates into the required sizes, for cobalt plates that need to be cut into small block-shaped bodies, generally, the whole cobalt plate needs to be manually placed on the strip-shaped shearing equipment first, cut into strip-shaped bodies, and then manually transferred to another block-shaped shearing equipment for continuous conveying. And the shearing member of another block-shaped shearing equipment is used to cut the strip-shaped cobalt plates into multiple block-shaped bodies. It is not convenient to complete continuous shearing directly through a set of equipment, and manual transfer processing is required in the middle, which is inconvenient to operate and has low shearing efficiency. Summary of the Invention

[0015] Preferably, a shearing support mechanism is arranged below the strip-shaped blanking opening. The shearing support mechanism includes a lifting plugging support member and a lifting driving member. The lifting plugging support member is matched with the U-shaped pushing frame through the lifting driving member.

[0019] The beneficial effects of the present invention:

[0020] 1. The present invention drives the main cutter to cut the cobalt plate into strip-shaped cobalt plate bodies by a hydraulic telescopic rod, and in the process of the hydraulic telescopic rod driving the main cutter to descend, it also drives the U-shaped push frame set by the extrusion of the inclined push rod to move horizontally. During this process, the first spring accumulates force. After the main cutter rises, the U-shaped push frame is reset by releasing the elastic force of the first spring, and the strip cobalt plate body that is pushed and cut off moves horizontally to contact the positioning baffle to achieve positioning. When the hydraulic telescopic rod drives the main cutter to descend again, the auxiliary cutter descends synchronously, so that the strip cobalt plate body that was pushed to the positioning baffle last time is cut into multiple blocks, thereby realizing continuous shearing of cobalt plates, without the need for manual transfer operation and processing, and improving operation efficiency.

[0021] 2. When the hydraulic telescopic rod of the present invention drives the main cutter to rise and reset, it pulls the clamping plates distributed on both sides of the positioning baffle to slide toward the middle through the traction wire, so as to facilitate the clamping of the strip cobalt plate body leaning against one side of the positioning baffle to make it centered. In this way, when the auxiliary cutter descends to cut, it is convenient to evenly cut the strip cobalt plate body into multiple pieces for subsequent use.

[0022] 3. Every time the U-shaped push frame of the present invention moves away from the positioning baffle under the pushing action of the inclined push rod, it can rely on the first rack, the linkage gear and the second rack to drive the corresponding extrusion rod to move horizontally close to the position below the positioning baffle, and the extrusion rod and the inclined extrusion block under the blocking block squeeze together, so that the blocking block is squeezed and pushed into the strip blanking port to achieve blocking, and the upper surface of the blocking block is flush with the surface of the receiving platform, so that it is convenient to effectively support the cobalt plate when it is cut, to ensure the cutting effect, to avoid the cobalt plate material body directly flying out from the bottom of the strip blanking port during the cutting process, or to avoid position displacement before complete cutting, which affects the cutting effect.

[0035] The following describes the specific embodiments of the present invention in detail, but it should be understood that the protection scope of the present invention is not limited by the specific embodiments.

[0036] Such as Figures 1 - 10As shown in the figure, a numerical control cobalt plate shearing device includes a shearing table 1, a main cutting knife 39, and a step feeding mechanism. The shearing table 1 includes four supporting legs. The cobalt plate parts are placed on the shearing table 1. The step feeding mechanism is used to intermittently push the cobalt plate parts close to the main cutting knife 39. One side of the shearing table 1 is fixedly installed with a hydraulic telescopic rod 5 for driving the main cutting knife 39 to move up and down through a bracket, which is convenient for cutting the intermittently fed cobalt plate parts into strip-shaped cobalt plates. A receiving table 10 is arranged below the main cutting knife 39, and the receiving table 10 is used to catch the cut cobalt plate strips. The shearing device also includes a pushing and positioning mechanism and an auxiliary cutting mechanism. The pushing and positioning mechanism includes a U-shaped pushing frame 17 and an elastic energy storage mechanism. One side of the receiving table 10 is fixedly connected with a positioning baffle 11 aligned with the U-shaped pushing frame 17, and a discharging mechanism is arranged on the side of the receiving table 10 close to the positioning baffle 11. The hydraulic telescopic rod 5 is controlled by the control system of the numerical control center. When the hydraulic telescopic rod 5 drives the main cutting knife 39 to descend, the elastic energy storage mechanism stores energy and drives the U-shaped pushing frame 17 away from the positioning baffle 11. When the hydraulic telescopic rod 5 drives the main cutting knife 39 to rise, the elastic energy storage mechanism releases elastic force to drive the U-shaped pushing frame 17 close to the positioning baffle 11. Thus, when the cut strip-shaped cobalt plate falls on the receiving table 10 and is between the positioning baffle 11 and the U-shaped pushing frame 17, after the main cutting knife 39 rises, the U-shaped pushing frame 17 pushes the strip-shaped cobalt plate to move close to the positioning baffle 11 to achieve positioning.

[0037] The auxiliary cutting mechanism includes a secondary cutting knife 7. A plurality of the secondary cutting knives 7 are arranged horizontally at equal intervals and are arranged on one side of the main cutting knife 39. The secondary cutting knives 7 descend synchronously with the main cutting knife 39 and are used to cut the strip-shaped cobalt plate positioned on one side of the positioning baffle 11 into a plurality of blocks, and are discharged from the receiving table 10 through the discharging mechanism for subsequent use.

[0038] In some specific implementation schemes, as shown in Figure 2 and Figure 4 the elastic energy storage mechanism includes a first connecting guide sleeve 16, a linkage plate 18, and a limiting cross plate 19. There are two of the first connecting guide sleeves 16, the linkage plate 18, and the limiting cross plate 19. The two first connecting guide sleeves 16 are respectively fixedly arranged below both sides of the shearing table 1 and can be specifically fixedly connected with the supporting legs. The two ends of the U-shaped pushing frame 17 respectively slide through the corresponding first connecting guide sleeves 16, and a first spring that can be stretched is connected between the U-shaped pushing frame 17 and the corresponding first connecting guide sleeves 16. The two linkage plates 18 are respectively fixedly connected to the two ends of the U-shaped pushing frame 17. The two limiting cross plates 19 are respectively horizontally fixedly arranged on both sides of the shearing table 1 and are correspondingly located below the linkage plates 18. The telescopic end of the hydraulic telescopic rod 5 is fixedly connected with a main mounting plate 8 for fixedly installing the main cutting knife 39, and movable pushing and propping members that cooperate with the linkage plates 18 are arranged on both sides of the main mounting plate 8.

[0039] Among them, the movable pushing member includes an inclined ejector rod 13. One end of the inclined ejector rod 13 is movably connected to the main mounting plate 8 through a return hinge, and the other end is rotatably connected with a top wheel that cooperates with the corresponding linkage plate 18.

[0040] When the hydraulic telescopic rod 5 drives the main cutting knife 39 to descend to a certain position, the inclined end of the inclined ejector rod 13 contacts the corresponding limiting cross plate 19 through the top wheel. At this time, the main cutting knife 39 has not yet descended to the position where the cobalt plate member is located. As the hydraulic telescopic rod 5 continuously drives the main cutting knife 39 to descend, the inclined ends of the inclined ejector rods 13 arranged on both sides of the main mounting plate 8 contact the limiting cross plate 19 through the top wheels. Due to the limitation of the limiting cross plate 19, the inclined ejector rod 13 is squeezed and deflected, and the inclined end rolls horizontally along the limiting cross plate 19 by relying on the top wheel, while pushing the corresponding linkage plate 18. The linkage plate 18 drives the U-shaped pushing frame 17 to slide horizontally away from the positioning baffle 11, and the first spring stretches to generate a resilience force. When the hydraulic telescopic rod 5 drives the main cutting knife 39 to descend to the corresponding position to complete the shearing of the strip-shaped cobalt plate body, it drives the main cutting knife 39 to rise. During the rising process, it drives the inclined ejector rod 13 to rise and reset synchronously. In this way, the U-shaped pushing frame 17 rebounds and resets under the resilience force of the first spring, so as to facilitate pushing the strip-shaped cobalt plate body falling on the receiving table 10 to move horizontally and approach the positioning baffle 11.

[0041] In some specific implementation schemes, in order to facilitate the uniform cutting of the strip-shaped cobalt plate body, as shown in Figure 1 and Figure 2 , clamping plates 15 are arranged on both sides of the receiving table 10 near the positioning baffle 11. A clamping driving mechanism is arranged between each clamping plate 15 and the receiving table 10, and the clamping driving mechanism cooperates with the telescopic end of the hydraulic telescopic rod 5. The two clamping plates 15 are used to clamp the strip-shaped cobalt plate body leaning against the positioning baffle 11 to make it centered and aligned below the secondary cutting knife 7.

[0042] Among them, the clamp driving mechanism includes a carriage 23, a second connecting guide sleeve 30 and a traction wire 21. The second connecting guide sleeve 30 is fixedly connected to the edge of the material receiving table 10. One end of the carriage 23 is fixedly connected to the corresponding clamping plate 15, and the other end slides through the corresponding second connecting guide sleeve 30. It should be noted that the cross-sections of the carriage 23 and the second connecting guide sleeve 30 are both square to prevent the carriage 23 from rotating. A compressible second spring 29 is connected between the carriage 23 and the corresponding second connecting guide sleeve 30. One end of the traction wire 21 is connected to the carriage 23, and the other end is connected to the telescopic end of the hydraulic telescopic rod 5. Specifically, a convex plate can be fixedly welded to one side of the main mounting plate 8 at the telescopic end of the hydraulic telescopic rod 5, and then the traction wire 21 is connected to the telescopic end of the hydraulic telescopic rod 5 through the convex plate. Above each carriage 23, a fixed pulley 22 cooperating with the corresponding traction wire 21 is provided. The fixed pulley 22 can be connected to the positioning baffle 11 through a wheel frame.

[0043] When the hydraulic telescopic rod 5 drives the main cutter 39 to descend to the position of cutting the cobalt plate, both clamping plates 15 are far away from the material receiving table 10 to avoid blocking the U-shaped push frame 17 from pushing the cut strip-shaped cobalt plate body to slide against the positioning baffle 11. When the hydraulic telescopic rod 5 contracts and drives the main cutter 39 to rise, the carriage 23 is pulled by the traction wire 21, and under the turning action of the fixed pulley 22, the carriage 23 is pulled to drive the clamping plates 15 to clamp towards the middle. In this way, the two clamping plates 15 clamp the strip-shaped cobalt plate body in the middle. During this process, the second spring 29 is compressed to generate a resilience force. When the hydraulic telescopic rod 5 drives the main cutter 39 to descend, the two clamping plates 15 can slide back and reset by relying on the resilience force of the second spring 29.

[0044] In some specific implementation schemes, in combination with Figure 2 , Figure 6 and Figure 7 as shown, the discharging mechanism includes a strip-shaped blanking port 24. The strip-shaped blanking port 24 is opened at the position of the material receiving table 10 close to the positioning baffle 11. The length and width of the strip-shaped blanking port 24 are both larger than the size of the cut strip-shaped cobalt plate body. A plurality of blocking rods 35 are horizontally and equidistantly arranged in the strip-shaped blanking port 24. The blocking rods 35 are cylindrical, and each blocking rod 35 is aligned with the central position between two adjacent secondary cutters 7.

[0045] When the U-shaped push frame 17 pushes the cut strip-shaped cobalt plate body to the position where the positioning baffle 11 is located, the strip-shaped cobalt plate body is exactly on the strip-shaped blanking port 24 and is supported by the blocking rods 35. When the secondary cutter 7 descends, the strip-shaped cobalt plate body is cut into multiple pieces, so as to facilitate falling between adjacent blocking rods 35.

[0046] In some specific implementation schemes, in combination with Figures 5 to 8As shown, a shearing support mechanism is provided below the strip-shaped blanking opening 24. The shearing support mechanism includes a lifting plugging support member and a lifting driving member. The lifting plugging support member is matched with the U-shaped pushing frame 17 through the lifting driving member. During the process of the U-shaped pushing frame 17 moving away from the positioning baffle 11, the lifting driving member drives the lifting plugging support member to rise and plug the strip-shaped blanking opening 24.

[0047] Among them, the lifting plugging support member includes a plugging block 31, a lifting slider 33 and a lifting guide rod 34. There are two lifting guide rods 34, which are symmetrically and fixedly connected to the bottom of the receiving table 10 and are located on one side of the strip-shaped blanking opening 24. The lifting slider 33 is slidably arranged on the lifting guide rod 34. Specifically, the lifting guide rod 34 penetrates through the lifting slider 33, and a limit block is fixedly arranged at the bottom of the lifting guide rod 34 to prevent the lifting slider 33 from falling off. The plugging block 31 is matched with the strip-shaped blanking opening 24, and one side of the bottom of the plugging block 31 is movably connected to one side of the bottom of the lifting slider 33 through a hinge. A bevel extrusion block 32 matched with the lifting driving member is also fixedly connected to the bottom of the plugging block 31. A plurality of grooves 36 aligned and matched with the stop rod 35 are equidistantly arranged on the plugging block 31, so as to ensure that the upper surface layer is flush with the upper surface layer of the receiving table 10 when the plugging block 31 is inserted into the strip-shaped blanking opening 24.

[0048] In addition, the lifting driving member includes a first rack 25, a second rack 27, a linkage gear 26 and an extrusion rod 28. The first rack 25 is fixedly arranged in parallel below the U-shaped pushing frame 17. A third connecting guide sleeve 40 is fixedly arranged below the shearing table 1. The third connecting guide sleeve 40 can be connected to the support leg below the shearing table 1 in the same way as the first connecting guide sleeve 16. The extrusion rod 28 horizontally slides through the third connecting guide sleeve 40, and the extrusion rod 28 is matched with the bevel extrusion block 32. The second rack 27 is fixedly connected to one end of the extrusion rod 28 away from the bevel extrusion block 32. The linkage gear 26 is engaged between the first rack 25 and the second rack 27, and the linkage gear 26 is connected to the support leg below the shearing table 1 through a shaft bracket, and the linkage gear 26 can rotate self. And two groups of extrusion rods 28 can be arranged. The ends of the second racks 27 on the two groups of extrusion rods 28 are fixedly connected together through a cross bar.

[0049] When the U-shaped pusher 17 slides away from the positioning baffle 11, it drives the first rack 25 to move synchronously. The first rack 25 then drives the second rack 27 to move in the reverse direction through the transmission of the linkage gear 26. The second rack 27 drives the extrusion rod 28 to move horizontally closer to the inclined surface extrusion block 32 at the bottom of the plugging block 31. Before the secondary cutter 7 descends to the position where it cuts the strip-shaped cobalt plate body, the extrusion rod 28 first touches the inclined surface extrusion block 32, pushing it to drive the plugging block 31 to rotate and align relative to the lifting slider 33. One side of the plugging block 31 is in contact with one side of the lifting slider 33, and at the same time, it is aligned directly below the strip-shaped blanking port 24 and has not entered the strip-shaped blanking port 24 yet. Then, as the extrusion rod 28 continues to move forward, an upward pushing component force is generated by relying on the extrusion action with the inclined surface of the inclined surface extrusion block 32. Since the lifting slider 33 can slide longitudinally along the lifting guide rod 34, the plugging block 31 can be pushed upward by the thrust force and snap into the strip-shaped blanking port 24 to block it. Finally, the upper surface of the plugging block 31 is flush with the upper surface of the material receiving table 10, which is convenient for effectively supporting the strip-shaped cobalt plate body to be sheared and facilitating subsequent stable cutting into multiple segments. Moreover, the extrusion rod 28 finally squeezes through the lowest position of the inclined surface of the inclined surface extrusion block 32 and slides relative to it, so that the plugging block 31 can be kept in the blocking position for a period of time, and at the same time, it is also convenient for the secondary cutter 7 to continue to descend for shearing. When the hydraulic telescopic rod 5 drives the main cutter 39 and the secondary cutter 7 to rise, it drives the inclined ejector rod 13 to rise and reset. In this way, the U-shaped pusher 17 slides back and resets under the resilience of the first spring, thereby driving the extrusion rod 28 to slide back and reset through the first rack 25, the linkage gear 26, and the second rack 27, and separating from the inclined surface extrusion block 32 at the bottom of the plugging block 31. In this way, the plugging block 31 disengages from the strip-shaped blanking port 24 under the action of gravity, facilitating the falling of the cobalt plate cut into multiple squares;

[0050] It should be noted that an inclined guide plate 12 can be arranged below the material receiving table 10 to catch the falling cobalt plate blocks and guide them to slide.

[0051] In some specific implementation schemes, as Figure 8 shown, one side of the telescopic end of the hydraulic telescopic rod 5 is fixedly provided with a secondary mounting plate 6 through an L-shaped plate body, and the position of the secondary mounting plate 6 is lower than the position of the main mounting plate 8; the secondary cutters 7 are horizontally and equidistantly distributed at the bottom of the secondary mounting plate 6. A pressing plate 9 parallel to the secondary mounting plate 6 is arranged below the secondary cutters 7, and a plurality of through holes aligned with the secondary cutters 7 are equidistantly opened on the pressing plate 9. Guide columns 37 penetrating the secondary mounting plate 6 are fixedly connected to both sides of the pressing plate 9, and the guide columns 37 can slide relative to the secondary mounting plate 6. A compressible limit spring 38 is also connected between the pressing plate 9 and the secondary mounting plate 6, and the limit spring 38 can be sleeved on the guide columns 37.

[0052] During the downward elongation of the hydraulic telescopic rod 5 to drive the main cutter 39 and the auxiliary cutter 7 to descend, the pressing plate 9 descends synchronously. At this time, the auxiliary cutter 7 does not pass through the through hole on the pressing plate 9. When the pressing plate 9 descends to the position where the strip-shaped cobalt plate body is located, the pressing plate 9 presses the strip-shaped cobalt plate body. At the same time, since the hydraulic telescopic rod 5 continues to drive the auxiliary cutter 7 downward, the auxiliary cutter 7 passes through the through hole and cuts the strip-shaped cobalt plate body into multiple cube-shaped bodies.

[0053] In some specific embodiments, an adjustable push plate 14 is provided on one side of the U-shaped push frame 17 close to the positioning baffle 11. The adjustable push plate 14 is slidably matched with the receiving table 10, that is, the bottom of the adjustable push plate 14 slides and fits on the receiving table 10. A regulating bolt 20 is threadedly connected to the U-shaped push frame 17, and one end of the regulating bolt 20 is rotatably connected to the adjustable push plate 14. The adjustable push plate 14 is driven by the regulating bolt 20 to move horizontally to adjust the position, so as to facilitate adjusting the initial distance between the adjustable push plate 14 and the positioning baffle 11 according to the width of the sheared strip-shaped cobalt plate body, and avoid the adjustable push plate 14 pressing the strip-shaped cobalt plate body too tightly against the positioning baffle 11, which affects the centering operation of clamping.

[0054] In some specific embodiments, the step-feed mechanism includes a step-type electric telescopic rod 3 and a guide plate 2. There are two guide plates 2, which are symmetrically and fixedly arranged on both sides of the shearing table 1. The guide plate 2 is an L-shaped plate body, and its size matches the size of the cobalt plate part to be pushed, and the cobalt plate part can be horizontally slid and clamped between the two guide plates 2; the step-type electric telescopic rod 3 is fixedly arranged on one side of the shearing table 1, and the telescopic end of the step-type electric telescopic rod 3 is fixedly connected with a pushing plate 4 that is located between the two guide plates 2. Relying on the intermittent elongation of the step-type electric telescopic rod 3, the cobalt plate part is continuously pushed forward by the pushing plate 4 and passes under the main cutter 39.

[0055] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0056] First, the cobalt plate part is clamped between the two guide plates 2 on the shearing table 1. Then, the operating frequencies of the step-type electric telescopic rod 3 and the hydraulic telescopic rod 5 are set through the numerical control system to ensure their cooperation. Ensure that each time the step-type electric telescopic rod 3 elongates to push the cobalt plate part forward a certain distance, so that the front end of the cobalt plate part exceeds the edge of the shearing table 1 by a certain width, and then the hydraulic telescopic rod 5 just starts to elongate downward, driving the main cutter 39 to descend and cut the exposed part of the cobalt plate part. Then, the hydraulic telescopic rod 5 drives the main cutter 39 to rise and reset. After rising and resetting, the step-type electric telescopic rod 3 pushes the cobalt plate part forward again. Repeating this way, it is convenient to cut the cobalt plate part into multiple strip-shaped cobalt plate bodies.

[0057] Each time the hydraulic telescopic rod 5 drives the main cutting knife 39 to descend to a certain position, the inclined end of the inclined ejector rod 13 touches the corresponding limiting horizontal plate 19 through the top wheel. At this time, the main cutting knife 39 has not descended to the position where it can cut the cobalt plate. As the hydraulic telescopic rod 5 continuously drives the main cutting knife 39 to descend, the inclined ends of the inclined ejector rods 13 arranged on both sides of the main mounting plate 8 touch the limiting horizontal plate 19 through the top wheels. Due to the limitation of the limiting horizontal plate 19, the inclined ejector rod 13 is squeezed and deflected, and the inclined end rolls horizontally along the limiting horizontal plate 19 relying on the top wheel, while pushing the corresponding linkage plate 18. The linkage plate 18 drives the U-shaped push frame 17 to slide horizontally away from the positioning baffle 11, and the first spring stretches to generate a resilience force. After the hydraulic telescopic rod 5 drives the main cutting knife 39 to descend to the corresponding position to complete the shearing of the strip-shaped cobalt plate body, the cut strip-shaped cobalt plate body falls on the material receiving table 10 and is located between the U-shaped push frame 17 and the positioning baffle 11.

[0058] When the hydraulic telescopic rod 5 drives the main cutting knife 39 to rise, it drives the inclined ejector rod 13 to rise and reset synchronously. In this way, the U-shaped push frame 17 rebounds and resets under the resilience force of the first spring, so as to facilitate pushing the strip-shaped cobalt plate body falling on the material receiving table 10 to horizontally move and touch the positioning baffle 11, and be located above the strip-shaped blanking port 24. Since the strip-shaped cobalt plate body has not been further cut at this time, it is convenient to be supported by the blocking rod 35.

[0059] And during the process of the hydraulic telescopic rod 5 contracting and driving the main cutting knife 39 to rise, the telescopic end of the hydraulic telescopic rod 5 pulls the sliding frame 23 through the traction wire 21, and under the steering action of the fixed pulley 22, pulls the sliding frame 23 to drive the opposing clamping plates 15 to clamp towards the middle. In this way, the two opposing clamping plates 15 clamp the strip-shaped cobalt plate body in the middle. During this process, the second spring 29 is compressed to generate a resilience force. It should be noted that before the U-shaped push frame 17 pushes the strip-shaped cobalt plate body to touch the positioning baffle 11, the opposing clamping plates 15 have not moved to the material receiving table 10, which can avoid interference.

[0060] When the hydraulic telescopic rod 5 drives the main cutting knife 39 to descend again, the auxiliary cutting knife 7 descends synchronously, and the pressing plate 9 also descends synchronously. At this time, the auxiliary cutting knife 7 does not pass through the through hole on the pressing plate 9. When the pressing plate 9 descends to the position where the strip-shaped cobalt plate body is located, the pressing plate 9 presses the strip-shaped cobalt plate body. At the same time, since the hydraulic telescopic rod 5 continues to drive the auxiliary cutting knife 7 downward, the auxiliary cutting knife 7 passes through the through hole and cuts the strip-shaped cobalt plate body into multiple cube-shaped bodies, realizing continuous shearing of the cobalt plate.

[0061] It should be noted that when the U-shaped pusher 17 slides away from the positioning baffle 11, it drives the first rack 25 to move synchronously. The first rack 25 then drives the second rack 27 to move in the reverse direction through the transmission of the linkage gear 26. The second rack 27 drives the extrusion rod 28 to laterally move closer to the inclined surface extrusion block 32 at the bottom of the plugging block 31. Before the secondary cutter 7 descends to the position where the strip-shaped cobalt plate body is cut off, the extrusion rod 28 first touches the inclined surface extrusion block 32, pushing it to drive the plugging block 31 to rotate and align relative to the lifting slider 33. One side of the plugging block 31 is attached to one side of the lifting slider 33, and at the same time, it is aligned directly below the strip-shaped blanking opening 24 and has not yet entered the strip-shaped blanking opening 24. Then, as the extrusion rod 28 continues to move forward, an upward pushing component force is generated by the extrusion action on the inclined surface of the inclined surface extrusion block 32. Since the lifting slider 33 can longitudinally slide along the lifting guide rod 34, the plugging block 31 can be pushed upward under the thrust force and snap into the strip-shaped blanking opening 24 to block it. Finally, the upper surface of the plugging block 31 is flush with the upper surface of the material receiving table 10, which is convenient for effectively supporting the strip-shaped cobalt plate body to be sheared and facilitating subsequent stable cutting into multiple segments. Moreover, the extrusion rod 28 finally squeezes through the lowest position of the inclined surface of the inclined surface extrusion block 32 and slides past it relatively, so that the plugging block 31 can be kept in the blocking position for a period of time, and at the same time, it is also convenient for the secondary cutter 7 to continuously descend for shearing. When the hydraulic telescopic rod 5 drives the main cutter 39 and the secondary cutter 7 to rise, it drives the inclined ejector rod 13 to rise and reset. In this way, the U-shaped pusher 17 slides back and resets under the resilience of the first spring, thereby driving the extrusion rod 28 to slide back and reset through the first rack 25, the linkage gear 26, and the second rack 27, and separating from the inclined surface extrusion block 32 at the bottom of the plugging block 31. In this way, the plugging block 31 disengages from the strip-shaped blanking opening 24 under the action of gravity, facilitating the falling of the cobalt plate cut into multiple squares.

[0062] The above discloses only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto, and any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
