Description

Technical Field

[0001] The present invention relates to the technical field of plate shearing machines, and particularly to a metal plate shearing machine device facilitating loading. Background Art

[0002] As a metal plate shearing tool, the principle of a plate shearing machine is to drive a shearing knife to press down through a transmission mechanism, thereby cutting the plate. According to the differences in the transmission mechanism, it can be divided into mechanical plate shearing machines, hydraulic plate shearing machines, and electric plate shearing machines. Among them, the hydraulic plate shearing machine is widely used in the field of metal plate cutting because of its large shearing force and easy operation.

[0003] In the prior art, a hydraulic plate shearing machine includes a machine base, a workbench, a shearing mechanism, and an electric control mechanism. Among them, the workbench is arranged on the top surface of the machine base, the shearing mechanism is arranged above the workbench, and the electric control mechanism is used to control the action of the shearing mechanism. During its specific use, the staff needs to first carry the metal plate to be cut onto the workbench, and then push the metal plate forward so that the front end of the metal plate extends below the shearing mechanism. Finally, the shearing mechanism is started to control the cutter to press down. After a section of the front end of the metal plate is sheared off, the staff continues to push the metal plate forward and then repeats the above actions, finally cutting a whole metal plate into multiple sections.

[0004] However, since metal plates generally have a certain weight, the staff is more laborious during the handling and loading process. At the same time, after each section is cut, the staff still needs to continue to push the metal plate forward, that is, the advancement of the metal plate is fully controlled manually, which also consumes human resources. For this reason, we have proposed a metal plate shearing machine device facilitating loading to well solve the above drawbacks. Summary of the Invention

[0005] The purpose of the present invention is to provide a metal plate shearing machine device facilitating loading to solve the problems raised in the above background art.

[0015] Optionally, the first roller shaft is of a hollow tubular structure. A driving shaft is movably inserted into the first roller shaft. The driving shaft is slidably connected to the first roller shaft along its own axial direction.

Detailed implementation manners

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figure 1 - Figure 8 , a shearing machine device for metal sheets that is convenient for loading, including a machine body 100 and a shearing mechanism 200. The machine body 100 includes a machine base 101, a workbench 102, and a frame 103. The workbench 102 is arranged on the top surface of the machine base 101, and the frame 103 is arranged on one side of the top surface of the workbench 102. A loading notch 104 is also formed on the workbench 102. An upper material mechanism 300 is arranged inside the machine base 101 and below the loading notch 104. The upper material mechanism 300 is used for storing the metal sheets to be processed. The shearing mechanism 200 is arranged inside the frame 103. One end of the bottom of the frame 103 facing the loading notch 104 also has a feeding port for the metal sheets to be processed to enter.

[0039] Specifically, the loading mechanism 300 includes a base plate 301, a scissor assembly 302, and a lifting plate 303. The base plate 301 is fixedly connected to the machine base 101. The scissor assembly 302 is disposed on the base plate 301, and the lifting plate 303 is disposed at the top end of the scissor assembly 302. The width of the lifting plate 303 is smaller than the inner width of the loading notch 104, and the top end of the lifting plate 303 is used for placing the metal plates to be processed. Therefore, the height of the lifting plate 303 can be directly controlled by the scissor assembly 302, so as to control the lifting of a plurality of metal plates. It should be noted that in this embodiment, the width and length of the adapted metal plates should be smaller than the corresponding length of the inner side of the loading notch 104, so as to avoid the situation that the plates cannot pass through the loading notch 104.

[0040] In addition, clamping assemblies 400 are provided on the top surface of the workbench 102 and on the left and right sides of the loading notch 104. The clamping assembly 400 includes a clamping cylinder 401 and a clamping portion 402. The cylinder block of the clamping cylinder 401 is fixedly connected to the top surface of the workbench 102, and the clamping portion 402 is disposed at the movable end of the clamping cylinder 401. The two clamping portions 402 are symmetrically distributed left and right. In the specific implementation process of this embodiment, when loading is required, the loading mechanism 300 first controls the rising of a plurality of stacked metal plates, so that the metal plate located on the top surface rises to the same height as the clamping portion 402, and then the clamping assemblies 400 located on both sides act, so as to control the two clamping portions 402 to clamp the topmost metal plate. Subsequently, the loading mechanism 300 controls the plurality of metal plates to descend to their original positions. At this time, only one metal plate is just clamped.

[0041] In some embodiments of this embodiment, receiving grooves 105 are formed on the left and right side walls of the loading notch 104. A rolling component 500 is disposed in the receiving groove 105. The rolling component 500 includes a holding frame 501 and a plurality of first roller shafts 502 rotatably disposed in the holding frame 501. The holding frame 501 is in the shape of a rectangular frame. The axial direction of the first roller shafts 502 is consistent with the width direction of the machine body 100, and the rolling component 500 is slidably connected to the receiving groove 105 along the axial direction of the first roller shafts 502. That is, the rolling component 500 can be retracted into the receiving groove 105 and can also extend outwards. Moreover, the diameter of the first roller shafts 502 is larger than the thickness of the holding frame 501, and the upper surface of the first roller shafts 502 is higher than the top surface of the holding frame 501.

[0042] Specifically, threaded connections are provided on both sides of the holding frame 501 with drive screws 503. The axial direction of the drive screws 503 is consistent with the axial direction of the first roller shaft 502. The drive screws 503 are rotationally engaged with the inner wall of the accommodation groove 105 through rotating seats 504. Installation notches 106 are provided on both the left and right sides of the bottom surface of the workbench 102, that is, the two installation notches 106 are respectively located on the left and right sides of the two accommodation grooves 105. One end of the drive screw 503 passes through the accommodation groove 105 and extends into the installation notch 106, and a first pulley 505 is fixedly sleeved on the end of the drive screw 503 that extends into the installation notch 106. An installation shaft 506 is provided on the inner wall of the machine base 101 and at a position directly below the first pulley 505. A second pulley 507 is rotatably provided on the outside of the installation shaft 506. A synchronous belt 508 is commonly sleeved on the outside of the first pulley 505 and the second pulley 507. Therefore, as long as the synchronous belt 508 rotates, it can drive the first pulley 505 to rotate, thereby indirectly controlling the contraction or extension of the holding frame 501.

[0043] Connecting rods 304 are provided at the four corner positions of the lifting plate 303. The four connecting rods 304 correspond to the four synchronous belts 508 one by one. The ends of the connecting rods 304 are connected to the corresponding synchronous belts 508 through connectors. When the lifting plate 303 moves upward, the holding frame 501 contracts toward the inside of the accommodation groove 105. Since the lifting plate 303 always moves up and down in the vertical direction, under the drive of the connecting rods 304, the four synchronous belts 508 can move synchronously, so that the rotation speeds and rotation directions of the drive screws 503 on both sides of the same holding frame 501 are kept consistent.

[0044] It should be noted that when the lifting plate 303 descends to the initial position, both holding frames 501 are in the extended state, and at this time, the width of the metal sheet to be processed should be greater than the distance between the two holding frames 501. In addition, it should be noted that the thickness of the metal sheets stacked on the lifting plate 303 should not be too high, otherwise when the lifting plate 303 rises, the metal sheet at the top will hit the lower surface of the holding frame 501. As for how many metal sheets can be stacked on the lifting plate 303 in this embodiment, it depends on the thickness and width of the metal sheets.

[0045] In summary, when the two clamping parts 402 clamp the metal sheet and the lifting plate 303 descends to the initial position, and then the clamping parts 402 release the metal sheet, the metal sheet will fall onto the two holding frames 501, and the lower surface of the metal sheet will be in contact with the first roller shaft 502.

[0046] In another embodiment of the present application, the first roller shaft 502 is a hollow tubular structure. A drive shaft 509 is movably inserted into the interior of the first roller shaft 502. The drive shaft 509 is slidably connected to the first roller shaft 502 along its own axial direction. One end of the drive shaft 509 passes through the holding frame 501 and the receiving groove 105 and extends into the mounting notch 106. And the end of the drive shaft 509 extending into the mounting notch 106; specifically, a guiding groove is axially formed on the surface of the drive shaft 509, and a guiding rib (not shown in the figure) that coincides with the guiding groove is protrudingly formed on the inner surface of the first roller shaft 502. Therefore, the first roller shaft 502 and the drive shaft 509 cannot rotate relative to each other.

[0047] In addition, a plurality of shaft grooves are evenly formed on the top surface of the workbench 102 and on the side of the feeding notch 104 close to the frame 103. A second roller shaft 107 is rotatably provided in each of the plurality of shaft grooves. Shaft rods 108 are coaxially connected to both ends of the second roller shaft 107. Shaft holes (not shown in the figure) for inserting the shaft rods 108 are formed at both ends inside the shaft grooves. And the shaft holes communicate with the corresponding mounting notches 106. One end of the shaft rod 108 passes through the shaft hole and extends into the mounting notch 106. And third pulleys 510 are coaxially connected to the ends of the shaft rod 108 and the drive shaft 509 extending into the mounting notch 106. A plurality of third pulleys 510 on the same side are commonly connected by a transmission belt 511. The third pulleys 510 also adopt synchronous belts to ensure that the synchronous belt 508 can accurately drive a plurality of third pulleys 510 to rotate synchronously.

[0048] A drive motor 109 is fixedly provided on one side of the workbench 102. The output shaft of the drive motor 109 extends into the mounting notch 106 and is coaxially and fixedly connected to one of the shaft rods 108. Therefore, the drive motor 109 can drive a plurality of first roller shafts 502 and second roller shafts 107 to rotate synchronously. It is worth mentioning that the central axis heights of the first roller shaft 502 and the second roller shaft 107 are the same, and the diameters of the first roller shaft 502 and the second roller shaft 107 are also the same. The function is to enable the metal sheet to move smoothly on the first roller shaft 502 and the second roller shaft 107.

[0049] Specifically in this embodiment, when the two clamping parts 402 lower the metal sheet, the metal sheet will fall onto the two holding frames 501. At this time, under the rotation of the first roller shaft 502 and the second roller shaft 107, the metal sheet can move smoothly and advance toward the side close to the feeding port.

[0050] In another embodiment of the present application, the shearing mechanism 200 includes a hydraulic cylinder 201 distributed vertically. The cylinder body of the hydraulic cylinder 201 is fixedly connected to the frame 103. The movable end of the hydraulic cylinder 201 is connected with a lifting part 202. A shearing knife 203 and an elastic pressing plate assembly 204 are arranged at the bottom end of the lifting part 202. In the natural state, the bottom surface of the elastic pressing plate assembly 204 is lower than the bottom end of the shearing knife 203. The elastic pressing plate assembly 204 includes a spring and a pressing block. Since this is prior art, it will not be elaborated here.

[0051] A fixed block 600 is also arranged inside the frame 103 and at a position opposite to the feeding port. A pushing screw 601 is threadedly connected to the fixed block 600. A stop block 602 is rotatably arranged at one end of the pushing screw 601 close to the feeding port. The stop block 602 is slidably matched with the frame 103 along the axial direction of the pushing screw 601, and the sliding direction of the stop block 602 is consistent with the translation direction of the metal plate. By rotating the pushing screw 601, the specific position of the stop block 602 can be adjusted to adapt to different shearing requirements.

[0052] Inner embedding grooves are formed on the top surface of the workbench 102 and on the front and rear sides of a plurality of second roller shafts 107. A jacking part 700 is movably arranged in each of the two inner embedding grooves, and one of the inner embedding grooves is located directly below the stop block 602. A moving part 701 is movably arranged below the workbench 102. A return spring 702 is connected between the moving part 701 and the bottom surface of the workbench 102. A guide rod 703 distributed vertically is arranged at the bottom surface of the jacking part 700. The bottom end of the guide rod 703 penetrates the bottom wall of the inner embedding groove and is fixedly connected to the moving part 701. The guide rod 703 and the bottom wall of the inner embedding groove are slidably matched vertically. In the natural state, the return spring 702 is in a compressed state, that is, the return spring 702 has a downward thrust on the moving part 701, and when the moving part 701 is not affected by the external force of the system, the top surface of the jacking part 700 is always lower than the upper surface of the workbench 102, and the function is to avoid hindering the translation of the metal plate.

[0053] Furthermore, driven racks 704 are arranged on the left and right sides of the moving part 701, and driving racks 205 are arranged at the left and right ends of the lifting part 202. The bottom ends of the two driving racks 205 respectively penetrate the workbench 102 and extend into the left and right sides of the moving part 701. Driven gears 705 are meshed between the driving racks 205 and the driven racks 704. The driven gears 705 are rotatably connected to the inner wall of the machine base 101 through mounting seats 706. Specifically, in this embodiment, the driven gears 705 and the driven racks 704 are always in a meshed state. In the initial state, the bottom end of the driving rack 205 is located above the driven gear 705. When the lifting part 202 descends, the driving rack 205 descends synchronously, and finally the driving rack 205 also meshes with the driven gear 705, thereby driving the moving part 701 to rise.

[0054] In summary, during the actual application of this embodiment, under the driving action of the first roller shaft 502 and the second roller shaft 107, the metal sheet gradually moves towards the feeding port. When the front end of the metal sheet abuts against the stopper 602, the hydraulic cylinder 201 drives the lifting part 202 to descend. As the lifting part 202 descends, the elastic pressing plate assembly 204 will first contact the upper surface of the sheet and press the sheet tightly, and then the shearing knife 203 will cut downward, thereby cutting off a section of the sheet at the front end.

[0055] After a section at the front end of the metal sheet is cut off, the lifting part 202 rises to release the sheet. Then, under the action of the second roller shaft 107, the remaining sheet will continue to move forward, and then the above actions are repeated, and finally the metal sheet is cut into strip-shaped structures.

[0056] It is worth mentioning that as the lifting part 202 descends, the driving rack 205 will also descend and drive the driven gear 705 to rotate, thereby causing the jacking part 700 to move upward and lift the metal sheet by a certain distance. The function is to avoid rolling friction between the second roller shaft 107 and the bottom surface of the metal sheet during the shearing process. Because this rolling friction will damage the bottom surface of the sheet on the one hand, and on the other hand, the frictional resistance may also damage the driving motor 109. It should be noted that since the driving rack 205 does not contact the driven gear 705 in the initial state, during the downward pressing process of the lifting part 202, the jacking part 700 first remains stationary and then makes an upward movement; and in the state without a metal sheet, during the downward pressing process of the lifting part 202, when the bottom surface of the elastic pressing plate assembly 204 just contacts a jacking part 700 located below it, at this time, the top surface of the jacking part 700 is slightly higher than the top surface of the second roller shaft 107.

[0057] In addition, it should be added that a jacking part 700 located below the elastic pressing plate assembly 204 and the opposite surface of the shearing knife 203 are in the same vertical plane, that is, when the shearing knife 203 presses downward, the jacking part 700 and the shearing knife 203 will form a lower blade and an upper blade, thereby completing the cutting of the metal sheet.

[0058] It should be noted that, in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprising", "including" or any other variant thereof are intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising an..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0059] Although the embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
