Description

Technical Field

[0001] This invention relates to the field of disc cutter cutting technology, specifically to a metal product edge cutting device. Background Technology

[0002] In the manufacturing process of a metal disc, the metal sheet needs to be cut using a cutting device to form a circular structure. The cutting device currently used employs two interlaced, oppositely rotating discs to generate shearing force, which gradually advances from the outside towards the center of the metal sheet, thus cutting the rotating metal sheet and ultimately shaping it into a circle.

[0003] However, when this sequentially advancing disc cutter cuts sheet metal, its cutting path exhibits a spiral shape (such as...). Figure 11 (As shown). During the cutting process, the cut metal sheets are continuously discharged from the other side of the disc cutter in long strips, and they oscillate irregularly. Because the edges of the cut metal sheets are quite sharp, this irregular oscillation poses a significant safety hazard. Specifically, the cut sheets may cut the equipment's wiring, scratch the machine surface, and may even cause injury to personnel. More seriously, as the length of the cut sheets increases, the area covered by their irregular oscillation also expands, further increasing the area with potential safety hazards. Summary of the Invention

[0004] The purpose of this invention is to provide a metal product cutting device that solves the problem that when existing cutting devices cut metal sheets, the cut pieces swing irregularly and increase in length, leading to an expansion of the safety hazard area and making it easy to cut wires, scratch the machine, and injure people.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a metal product trimming device, comprising:

[0006] The upper and lower corresponding clamping mechanisms and rotating base mechanisms work together to clamp the metal sheet and cause the metal sheet to rotate horizontally along the middle.

[0007] The edge-cutting mechanism includes two rotating disc cutters, one and two, mounted on one side via a rotating shaft and the other on a rotating shaft, which rotate in opposite directions. The edge-cutting mechanism drives the rotating disc cutters to advance towards the metal sheet, cutting the rotating metal sheet and producing cut pieces.

[0008] The material cutting mechanism includes a movable frame assembly assembled between a first rotating shaft and a second rotating shaft, and a cutting assembly assembled at one end of the movable frame assembly. The movable frame assembly includes a pair of parallel crossbars, which cooperate with the first rotating shaft and the second rotating shaft to drive the cutting assembly to continuously cut the moving piece of fabric.

[0009] As a further description of the above technical solution: the two crossbeams are eccentrically mounted on corresponding rotating shafts one and two via bearings two in their respective middle sections.

[0010] As a further description of the above technical solution: both ends of the pair of cross frames are connected to longitudinal shafts. One end of the longitudinal shaft is fixedly connected to a cross frame, and the other end is slidably connected to another cross frame through a linear bearing. The linear bearing is fixed on the cross frame, and the longitudinal shaft is used to limit the two cross frames to maintain a corresponding parallel state during movement.

[0011] As a further description of the above technical solution: the cutting assembly includes a pair of cutters, the two cutters are respectively mounted on one side of two crossbeams through their respective fixing seats, and the two cutters are driven by the corresponding crossbeams to cut the moving piece of fabric in an adaptive manner.

[0012] As a further description of the above technical solution: the blades of the pair of cutters are symmetrically inclined.

[0013] As a further description of the above technical solution: a clamping assembly is assembled on one side of the cutting assembly. The clamping assembly clamps the cutting piece before the cutting assembly cuts the cutting piece, so that the cutting piece and the cutting assembly move synchronously.

[0014] As a further description of the above technical solution: the clamping plate assembly includes two mounting frames assembled on one side of two cross frames. The two mounting frames are symmetrical from top to bottom. Vertically movable support rods are mounted on the mounting frames. A clamping block is fixed at one adjacent end of each of the two support rods. A spring is sleeved on the surface of each of the two support rods to push the two clamping blocks to clamp each other. The clamping surface of the clamping block protrudes from the cutting edge of the cutter.

[0015] As a further description of the above technical solution: the two clamping blocks are inclined in opposite directions, so that when the cut piece is clamped, the side of the cut piece away from the cutter bends downward.

[0016] As a further description of the above technical solution: a guide component is provided on one side of the cutting component, and the guide component guides the cut piece through the cutting area of ​​the cutting component.

[0017] As a further description of the above technical solution: the guiding assembly includes a guide plate one, the guide plate one being bent upward at one end near the disc cutter two, and outwardly bent guide plates two being fitted on both sides of the guide plate one. The guide plate one is fitted to one side of a pair of crossbeams by a fixing assembly, so that the guide plate one moves horizontally with the crossbeams and maintains a height position. The fixing assembly includes a positioning frame that is movably inserted in the middle of the pair of crossbeams. Spring two is sleeved at each end of the positioning frame. The guide plate one is fitted to one side of the cutting assembly by a support frame that is fixedly connected in the middle of the positioning frame.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0019] 1. During the corresponding rotation operation of pivot one and pivot two, when the horizontal frame and the cutting piece move in the same direction, a pair of cutters are driven by the horizontal frame to first move closer to each other and cut the cutting piece moving in the same direction. After cutting, they move further apart. When the horizontal frame and the cutting piece move in opposite directions, they return to their starting position, and the cutters continue to move vertically away during the initial horizontal movement, ensuring that the cutting piece is located in the preset position between the pair of cutters. Through the cyclic process, the pair of cutters continuously cut the forward cutting piece, cutting it into multiple segments, thereby avoiding irregular swinging of the cutting piece due to excessive length, and thus eliminating the safety hazards caused by it.

[0020] 2. The cutting piece is clamped and fitted by the clamping assembly to ensure that the cutting piece in the middle of the cutting assembly moves synchronously with the cutting assembly, thereby ensuring that the cutting assembly can cut the cutting piece smoothly. When the clamping assembly releases the cutting piece, it can also ensure that the cutting piece is guided between the two cutters, providing a guarantee for the subsequent cutting task of the cutting assembly.

[0021] 3. The guide plate is mounted on one side of a pair of crossbeams by a fixing assembly, so that it can move horizontally with the crossbeams and maintain a height position, thereby ensuring that the cut pieces guided by the guide plate can be accurately aligned with the cutting assembly.

[0038] 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.

[0039] To further understand the content of this invention, a detailed description of the invention will be provided in conjunction with the accompanying drawings.

[0040] Combination Figures 1-15 A metal product trimming device, comprising:

[0041] The upper and lower corresponding clamping mechanism 30 and rotating base mechanism 40 are composed of a rotating base and a servo motor on the lower side for driving the rotating base to rotate. The clamping mechanism 30 is composed of a telescopic component (such as an electric cylinder or a pneumatic cylinder) and a turntable rotatably connected to the output end. The telescopic component pushes the turntable to cooperate with the rotating base to clamp the metal plate 50. The servo motor controls the rotating base to rotate, causing the metal plate 50 to rotate horizontally along the middle.

[0042] The edge-cutting mechanism 10 includes a machine base and two opposing rotating disc cutters 13 and 14, which are respectively mounted on one side of the machine base via a rotating shaft 11 and a rotating shaft 2 12. The machine base is slidably mounted on the table surface. Another telescopic component is provided on one side of the machine base. The telescopic component pushes the edge-cutting mechanism 10 to move, which drives the rotating disc cutter 13 and 14 to advance towards the metal sheet 50, cuts the rotating metal sheet 50, and produces a cut piece 51. During the cutting process, the length of the cut piece 51 continuously increases and it continues to move in the corresponding direction.

[0043] The shredding mechanism 20 includes a movable frame assembly 21 mounted between a first rotating shaft 11 and a second rotating shaft 12, and a cutting assembly 22 mounted at one end of the movable frame assembly 21. The movable frame assembly 21 includes a pair of parallel crossbeams 211. The two crossbeams 211 are eccentrically mounted on the corresponding first rotating shaft 11 and second rotating shaft 12 via bearings 214 at their respective centers. Both ends of the pair of crossbeams 211 are connected to longitudinal shafts 212. One end of the longitudinal shaft 212 is fixedly connected to one crossbeam 211, and the other end is fixedly connected to the other crossbeam 211. The end is slidably connected to another crossbeam 211 via a linear bearing 213. The linear bearing 213 is fixedly mounted on the crossbeam 211. The longitudinal shaft 212 is used to limit the movement of the two crossbeams 211 to maintain their corresponding parallel state. The cutting assembly 22 includes a pair of cutters 221. The two cutters 221 are correspondingly mounted on one side of the two crossbeams 211 via their respective fixed seats 222. The two cutters 221 are driven by the corresponding crossbeams 211 to cut the moving piece 51 in an adaptive manner.

[0044] like Figures 12 to 15 As shown, when rotating shaft 11 and rotating shaft 12 perform corresponding rotation operations (as indicated by the arrows in the figure), the crossbeam 211 moves along a circular trajectory and always remains horizontal and parallel. The circular motion trajectories of the two crossbeams 211 are symmetrically distributed vertically. Combined with... Figure 13 → Figure 14 → Figure 15 In this sequence, the horizontal frame 211 moves from left to right, its direction of movement being consistent with the direction of movement of the cut piece 51. During this process, a pair of cutters 221, driven by the horizontal frame 211, first move closer to each other during the movement, cutting the cut piece 51 that is moving in the same direction (e.g., ...). Figure 14As shown, the vertical dotted line indicates the position where a pair of cutters 221 cut the cut piece 51 (this position will be referred to as the cutting section). After cutting, the cutters 221 move away from each other to prevent the cut part of the cut piece 51 from hitting the side of the crossbar 211 while it is moving forward, thereby preventing the cut piece 51 from being misled to other positions and unable to pass normally between the two cutters 221.

[0045] Subsequently, combined Figure 15 → Figure 12 → Figure 13 In this sequence, the horizontal frame 211 returns from the right to the left, its direction of movement opposite to that of the cutting piece 51. During this process, the pair of cutters 221 continue to move vertically away during the initial horizontal movement, and their horizontal movement direction is opposite to that of the cutting piece 51, further ensuring that the cutting piece 51 is always in the middle position of the pair of cutters 221. Through the above cyclic action, the pair of cutters 221 can continuously cut the advancing cutting piece 51, cutting it into multiple segments, thereby effectively preventing the cutting piece 51 from swinging irregularly due to excessive length, and thus eliminating the safety hazards caused by this.

[0046] Furthermore, such as Figure 8 As shown, the blades of the pair of cutters 221 are symmetrically inclined. When cutting the cut piece 51, its cutting principle is similar to that of scissors, which can better generate cutting force and ensure that the cut piece 51 can be cut smoothly.

[0047] like Figure 9 and Figure 10 As shown, there is an intersection region between disc cutter 13 and disc cutter 2 14 (e.g. Figure 10 (The shaded area in the image). The second disc cutter 14 is located on the side closer to the metal sheet 50, while the first disc cutter 13 is located on the side farther from the metal sheet 50. A cutting section is formed on the left side of the intersection of the first disc cutter 13 and the second disc cutter 14, used for cutting the metal sheet 50.

[0048] However, some factors may affect the normal cutting effect of the cutting component 22 during the cutting process, as follows:

[0049] On the one hand, the production speed of the cut piece 51 is consistent with the rotational speed of the arc surface of the disc blade 214, so the horizontal movement speed of the cut piece 51 will be greater than the horizontal movement speed of the cutter 221. On the other hand, the top arc surface of the disc blade 214 is higher than the cutting part, and the cut piece 51 will be pushed upward by the top of the disc blade 214 after cutting. These factors may all cause the cutting assembly 22 to fail to achieve the ideal cutting effect in the subsequent cutting process.

[0050] It should be noted that the first disc cutter 13 and the second disc cutter 14 have the same diameter, and the rotation speed of the metal sheet 50 is matched with the rotation speed of the first disc cutter 13 and the second disc cutter 14, thereby ensuring that the first disc cutter 13 and the second disc cutter 14 can smoothly cut the metal sheet 50.

[0051] In addition, it is necessary to further clarify the definitions of relevant terms: the shearing section refers to the part where a pair of cutters 221 cut the cut piece 51; the cutting section refers to the part where the disc cutter 13 and the disc cutter 24 cut the metal sheet 50.

[0052] To address the issue that the horizontal movement speed of the cutter piece 51 is greater than the horizontal movement speed of the cutter 221, thus affecting the smooth cutting of the cutter piece 51 by the cutting assembly 22, this embodiment adopts the following solution:

[0053] like Figures 6 to 8 As shown, a clamping assembly 23 is mounted on one side of the cutting component 22. The clamping assembly 23 includes two mounting brackets 234, which are respectively mounted on one side of the two crossbeams 211 and are symmetrically distributed vertically. Each mounting bracket 234 is equipped with a vertically movable support rod 232, and a clamping block 231 is fixed to the adjacent end of each of the two support rods 232. A spring 233 is sleeved on the surface of each support rod 232, and the function of the spring 233 is to push the two clamping blocks 231 to clamp each other. The clamping surface of the clamping block 231 protrudes from the cutting edge of the cutter 221. In this way, even if the moving speed of the cut piece 51 is greater than the moving speed of the cutter 221, the clamping assembly 23 can clamp the cut piece 51 before the cutting component 22 is about to cut it, ensuring that the cut piece 51 in the middle of the cutting component 22 moves synchronously with the cutting component 22, thereby ensuring that the cutting component 22 can smoothly cut the cut piece 51. In addition, when the clamping assembly 23 releases the cut piece 51, it can also ensure that the cut piece 51 is guided between the two cutters 221, thus providing a guarantee for the subsequent cutting task of the cutting assembly 22.

[0054] Furthermore, the clamping surfaces of the two clamping blocks 231 are inclined accordingly. When clamping the cut piece 51, the side of the cut piece 51 away from the cutter 221 will bend downwards. Thus, after the pair of clamping blocks 231 clamp the cut piece 51, although the movement speed of one side of the cut piece 51 is relatively fast and the length continues to increase, the increased length will be adapted to the curvature of its bending. As the clamping blocks 231 release the cut piece 51, the cut piece 51 will automatically return to a horizontal state due to its own elasticity (similar to the recovery of a bent spring). In the initial stage after the clamping blocks 231 release the cut piece 51, it actively extends towards the middle of the two cutters 221 to ensure that the cut piece 51 accurately enters the cutting part of the cutting assembly 22, thereby further ensuring the normal progress of subsequent cutting operations.

[0055] To address the problem that the cut piece 51 is pushed upwards by the top of the disc blade 14, thus affecting its smooth entry into the cutting section of the cutting assembly 22, this embodiment adopts the following solution:

[0056] like Figure 5 and Figure 6 As shown, a guide assembly 24 is provided on one side of the cutting assembly 22. The guide assembly 24 includes a guide plate 244, the end of which is bent upward near the disc cutter 14, which can guide the upward-curving piece 51, allowing it to smoothly enter the cutting section of the cutting assembly 22 along the lower surface of the guide plate 244. Outwardly bent guide plates 245 are fitted on both sides of the guide plate 244 to prevent the piece 51 from deviating to either side, thus avoiding deviation of the piece 51 from the cutting section of the cutting assembly 22. The guide plate 244 is mounted on one side of a pair of crossbeams 211 by a fixing assembly, allowing it to move horizontally with the crossbeams 211 and maintain its height position, thereby ensuring that the piece 51 guided by the guide plate 244 can accurately align with the cutting assembly 22 (if the guide plate 244 is only fixed to the side of the machine, the distance between one end of it and the cutting assembly 22 and the clamping assembly 23 will vary, resulting in a poorer alignment).

[0057] It should be noted that the movement areas of the support frame 243 and guide plate 244 should avoid collisions with the disc cutter 13 and disc cutter 244.

[0058] The fixing component includes a positioning frame 241, which is movably inserted in the middle of a pair of crossbeams 211. Two springs 242 are fitted at both ends of the positioning frame 241, and the two springs 242, through elastic action, push the fixing block in the middle of the positioning frame 241 to maintain it in the middle position of the pair of crossbeams 211. A guide plate 244 is assembled to one side of the cutting component 22 via a support 243 fixedly connected to the middle of the positioning frame 241, thereby ensuring that the horizontal height of the guide plate 244 is maintained at a preset position.

[0059] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
