Description

Technical Field

[0001] This invention relates to the field of shearing machine technology, specifically to a metal sheet shearing machine device that facilitates material loading. Background Technology

[0002] A shearing machine, as a tool for cutting metal sheets, works by using a transmission mechanism to drive a shearing blade downwards, thereby cutting the sheet metal. Based on differences in the transmission mechanism, shearing machines can be divided into mechanical shearing machines, hydraulic shearing machines, and electric shearing machines. Among these, hydraulic shearing machines are widely used in the field of metal sheet cutting due to their high shearing force and ease of operation.

[0003] In existing technology, a hydraulic shearing machine includes a base, a worktable, a shearing mechanism, and an electrical control mechanism. The worktable is located on the top surface of the base, the shearing mechanism is positioned above the worktable, and the electrical control mechanism controls the operation of the shearing mechanism. In practical use, the operator first moves the metal sheet to be cut onto the worktable, then pushes the sheet forward until its front end extends below the shearing mechanism. Finally, the shearing mechanism is activated to control the cutting blade to press down. After the front end of the metal sheet is cut off, the operator continues to push the sheet forward and repeats the above actions, ultimately cutting a single piece of metal into multiple segments.

[0004] However, since sheet metal generally has a certain weight, it is quite strenuous for workers to handle and load it. Furthermore, after each section is cut, workers need to continue pushing the sheet metal forward, meaning the entire process is manually controlled, which also consumes manpower. Therefore, we propose a sheet metal shearing machine device that facilitates loading, effectively solving the aforementioned drawbacks. Summary of the Invention

[0016] The top surface of the workbench, on the side near the loading notch close to the frame, is provided with several shaft grooves.

[0023] Compared with the prior art, the present invention provides a metal sheet shearing machine device that facilitates material feeding, and has the following beneficial effects:

[0024] 1. The present invention has a feeding mechanism, and the cooperation between the feeding mechanism and the clamping assembly can automatically realize the sequential feeding of metal sheets, thereby eliminating the need for manual feeding by workers and greatly reducing the labor intensity of workers;

[0025] 2. In this invention, both the first roller and the second roller are driven by a motor. Therefore, when the metal sheet is placed on the worktable, the metal sheet can automatically move towards the shearing mechanism under the combined action of the first roller and the second roller, thus eliminating the need for manual pushing and helping to free up manpower.

[0026] 3. When the shearing blade of the present invention presses down, the lifting part can automatically rise and lift the metal plate upward a certain distance, thereby avoiding the metal plate and the roller shaft from sticking together during the shearing process, so as to avoid damage to the bottom surface of the metal plate or damage to the drive motor.

[0027] 4. When the lifting plate of the present invention rises, the two retaining frames can automatically retract inward, and when the lifting plate descends, the two retaining frames can automatically extend, thus achieving automated coordination without manual control, which greatly helps to improve the working efficiency of the present invention.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Please see Figure 1 - Figure 8 A metal sheet shearing machine for easy loading includes a body 100 and a shearing mechanism 200. The body 100 includes a base 101, a worktable 102, and a frame 103. The worktable 102 is disposed on the top surface of the base 101, and the frame 103 is disposed on one side of the top surface of the worktable 102. The worktable 102 also has a loading notch 104. A loading mechanism 300 is disposed inside the base 101 and below the loading notch 104. The loading mechanism 300 is used to store the metal sheet to be processed. The shearing mechanism 200 is disposed inside the frame 103. The bottom of the frame 103 and the end facing the loading notch 104 also has an inlet for the metal sheet to be processed to enter.

[0039] Specifically, the feeding mechanism 300 includes a base plate 301, a scissor lift assembly 302, and a lifting plate 303. The base plate 301 is fixedly connected to the machine base 101. The scissor lift assembly 302 is disposed on the base plate 301, and the lifting plate 303 is disposed at the top of the scissor lift assembly 302. The width of the lifting plate 303 is smaller than the inner width of the feeding notch 104, and the top of the lifting plate 303 is used to place the metal sheet to be processed. Therefore, the height of the lifting plate 303 can be directly controlled by the scissor lift assembly 302, thereby controlling the lifting of several metal sheets. It should be noted that the width and length of the metal sheet suitable for this embodiment should be smaller than the corresponding inner length of the feeding notch 104, so as to avoid the sheet being unable to pass through the feeding notch 104.

[0040] In addition, clamping components 400 are provided on the top surface of the workbench 102 and on both sides of the feeding notch 104. The clamping components 400 include clamping cylinders 401 and clamping parts 402. The cylinder body of the clamping cylinder 401 is fixedly connected to the top surface of the workbench 102. The clamping parts 402 are located at the movable end of the clamping cylinder 401. The two clamping parts 402 are symmetrically distributed on the left and right. In the specific implementation process of this embodiment, when feeding is required, the feeding mechanism 300 first controls several stacked metal plates to rise, so that the metal plate on the top surface rises to the same height as the clamping parts 402. Then the clamping components 400 on both sides move, thereby controlling the two clamping parts 402 to clamp the topmost metal plate. Then the feeding mechanism 300 controls several metal plates to descend to their original positions. At this time, only one metal plate is clamped.

[0041] In some embodiments of this example, the left and right side walls of the feeding notch 104 are provided with receiving grooves 105. The receiving grooves 105 are provided with a rolling assembly 500. The rolling assembly 500 includes a retaining frame 501 and a plurality of first rollers 502 rotatably disposed in the retaining frame 501. The retaining frame 501 is rectangular. The axial direction of the first rollers 502 is consistent with the width direction of the machine body 100. The rolling assembly 500 is slidably connected to the receiving groove 105 along the axial direction of the first rollers 502. That is, the rolling assembly 500 can be retracted into the receiving groove 105 or extended outward. Furthermore, the diameter of the first rollers 502 is greater than the thickness of the retaining frame 501, and the upper surface of the first rollers 502 is higher than the top surface of the retaining frame 501.

[0042] Specifically, both sides of the retaining frame 501 are threadedly connected to 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 rotatably engaged with the inner wall of the receiving groove 105 through the rotating seat 504. The bottom surface of the worktable 102 is provided with mounting slots 106 on both the left and right sides. That is, the two mounting slots 106 are located on the left and right sides of the two receiving grooves 105 respectively. One end of the drive screw 503 passes through the receiving groove 105 and extends into the mounting slot 106. The end of the drive screw 503 extending into the mounting slot 106 is fixedly fitted with a first pulley 505. The inner wall of the machine base 101 and located directly below the first pulley 505 is provided with a mounting shaft 506. A second pulley 507 is rotatably provided on the outside of the mounting shaft 506. The first pulley 505 and the second pulley 507 are both fitted with a synchronous belt 508. Therefore, as long as the synchronous belt 508 rotates, it can drive the first pulley 505 to rotate, thereby indirectly controlling the retraction or extension of the retaining frame 501.

[0043] Connecting rods 304 are provided at each of the four corners of the lifting plate 303. Each of the four connecting rods 304 corresponds to one of the four synchronous belts 508. 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 retaining frame 501 retracts into the receiving groove 105. Since the lifting plate 303 always moves up and down in a vertical direction, the four synchronous belts 508 can move synchronously under the drive of the connecting rods 304, so that the rotation speed and rotation direction of the drive screws 503 located on both sides of the same retaining frame 501 are consistent.

[0044] It should be noted that when the lifting plate 303 descends to the initial position, both retaining frames 501 are in the extended state, and the width of the metal sheet to be processed should be greater than the distance between the two retaining frames 501 at this time. In addition, it should be noted that the thickness of the metal sheet 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 retaining frame 501. As for the maximum number of metal sheets that can be stacked on the lifting plate 303 in this embodiment, it depends on the thickness and width of the metal sheet.

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

[0046] In another embodiment of this application, the first roller shaft 502 is a hollow tubular structure, and a drive shaft 509 is movably inserted inside the first roller shaft 502. The drive shaft 509 and the first roller shaft 502 are slidably connected along their own axial direction. One end of the drive shaft 509 passes through the retaining frame 501 and the receiving groove 105 and extends into the mounting groove 106. Specifically, the surface of the drive shaft 509 is provided with a guide groove along the axial direction, and the inner surface of the first roller shaft 502 is formed with a guide rib (not shown in the figure) that matches the guide groove. Therefore, the first roller shaft 502 and the drive shaft 509 cannot rotate relative to each other.

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

[0048] A drive motor 109 is fixedly mounted on one side of the worktable 102. The output shaft of the drive motor 109 extends into the mounting slot 106 and is coaxially and fixedly connected to one of the shafts 108. Therefore, the drive motor 109 can drive several first rollers 502 and second rollers 107 to rotate synchronously. It is worth mentioning that the central axis heights of the first rollers 502 and second rollers 107 are the same, and the diameters of the first rollers 502 and second rollers 107 are also the same, which allows the metal sheet to move smoothly on the first rollers 502 and second rollers 107.

[0049] Specifically in this embodiment, when the two clamping parts 402 put down the metal plate, the metal plate will fall onto the two holding frames 501. At this time, under the rotation of the first roller 502 and the second roller 107, the metal plate can move smoothly and move towards the side closer to the feed port.

[0050] In another embodiment of this application, the shearing mechanism 200 includes a vertically distributed hydraulic cylinder 201. 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 to a lifting part 202. The bottom end of the lifting part 202 is provided with a shearing blade 203 and an elastic pressure plate assembly 204. In its natural state, the bottom surface of the elastic pressure plate assembly 204 is lower than the bottom end of the shearing blade 203. The elastic pressure plate assembly 204 includes a spring and a pressure block, which is prior art and will not be described in detail here.

[0051] Inside the frame 103, directly opposite the feed inlet, is a fixing block 600. A push screw 601 is threaded onto the fixing block 600. A stop block 602 is rotatably mounted on the end of the push screw 601 near the feed inlet. The stop block 602 slides along the axial direction of the push screw 601 with the frame 103, and the sliding direction of the stop block 602 is consistent with the translation direction of the metal sheet. By rotating the push screw 601, the specific position of the stop block 602 can be adjusted to adapt to different shearing requirements.

[0052] The top surface of the worktable 102 and both the front and rear sides of several second rollers 107 are provided with embedded grooves. A lifting part 700 is movably installed in each of the two embedded grooves, with one of the embedded grooves located directly below the stop block 602. A moving part 701 is movably installed below the worktable 102. A return spring 702 connects the moving part 701 and the bottom surface of the worktable 102. The bottom surface of the lifting part 700 is provided with vertically distributed guide rods 703. The bottom end of the guide rods 703 penetrates the bottom wall of the embedded groove and is fixedly connected to the moving part 701. The guide rods 703 and the bottom wall of the embedded groove slide vertically. In its natural state, the return spring 702 is compressed; that is, the return spring 702 exerts a downward pushing force on the moving part 701. When the moving part 701 is not subjected to external force, the top surface of the lifting part 700 is always lower than the upper surface of the worktable 102, thus preventing obstruction of the translation of the metal sheet.

[0053] Furthermore, driven racks 704 are provided on both the left and right sides of the moving part 701, and driven racks 205 are provided on both the left and right ends of the lifting part 202. The bottom ends of the two driven racks 205 pass through the worktable 102 and extend into the left and right sides of the moving part 701, respectively. A driven gear 705 is meshed between the driven racks 205 and the driven racks 704. The driven gear 705 is rotatably connected to the inner wall of the base 101 through the mounting base 706. Specifically, in this embodiment, the driven gear 705 and the driven rack 704 are always in a meshed state. In the initial state, the bottom end of the driven rack 205 is located above the driven gear 705. When the lifting part 202 descends, the driven rack 205 descends synchronously, eventually causing the driven rack 205 to mesh with the driven gear 705, thereby driving the moving part 701 to rise.

[0054] In summary, in practical application, under the driving action of the first roller 502 and the second roller 107, the metal sheet gradually moves towards the feed port. When the front end of the metal sheet abuts against the stop block 602, the hydraulic cylinder 201 drives the lifting part 202 to descend. As the lifting part 202 descends, the elastic pressure plate assembly 204 will first contact the upper surface of the sheet and press the sheet tightly. Then the shearing blade 203 will cut down, thereby cutting off a section of the sheet at the front end.

[0055] After the front end of the metal sheet is cut off, the lifting part 202 rises again to release the sheet. Then, under the action of the second roller 107, the remaining sheet will continue to move forward. The above actions are repeated until the metal sheet is finally cut into strips.

[0056] It is worth mentioning that as the lifting section 202 descends, the active rack 205 also descends and drives the driven gear 705 to rotate, thereby causing the lifting section 700 to move upward and lift the metal sheet a certain distance. This is to avoid rolling friction between the second roller shaft 107 and the bottom surface of the metal sheet during the shearing process, because such rolling friction can damage the bottom surface of the sheet and the frictional resistance may also damage the drive motor 109. It should be noted that since the active rack 205 does not contact the driven gear 705 in the initial state, the lifting section 700 remains stationary during the downward pressing of the lifting section 202, and then moves upward. In the absence of a metal sheet, during the downward pressing of the lifting section 202, when the bottom surface of the elastic pressure plate assembly 204 just contacts the lifting section 700 located below it, the top surface of the lifting section 700 is slightly higher than the top surface of the second roller shaft 107.

[0057] Additionally, it should be noted that a lifting part 700 located below the elastic pressure plate assembly 204 and the facing surface of the shearing blade 203 are located in the same vertical plane. That is, when the shearing blade 203 is pressed down, the lifting part 700 and the shearing blade 203 will form the lower and upper cutting edges, 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 used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

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