Description

Technical Field

[0001] This application relates to the field of sheet metal processing technology, and in particular to a shearing machine. Background Technology

[0002] In the field of machining, sheet metal processing has always been a crucial component, widely used in numerous industries such as construction, automotive manufacturing, and aerospace. With the continuous development of the manufacturing industry, the demands for efficiency, precision, and quality in sheet metal cutting are increasing. Highly efficient and precise sheet metal cutting technology can significantly improve production efficiency and reduce production costs, playing a vital role in enhancing the competitiveness of the entire manufacturing industry. While meeting the needs of large-scale production, it can also support the manufacturing of complex components, driving improvements in the performance and quality of related products.

[0003] In the past, shearing operations typically employed simple structural combinations. Commonly, these consisted of only a simple upper and lower blade, with the upper blade moving downwards manually or using a basic power device to cut the sheet metal. Furthermore, material placement and securing were primarily done manually, a method that was not only inefficient but also difficult to guarantee in terms of accuracy and stability. Loading was also largely manual, resulting in high labor intensity and a large manpower investment. In addition, controlling the cutting length of the sheet metal relied on manual measurement and marking, making operation inconvenient and with low precision.

[0004] However, existing shearing methods have many obvious drawbacks. Manual material placement makes it difficult to ensure the accuracy and stability of the sheet metal, easily leading to displacement during cutting and affecting cutting precision and quality. Manual material loading is not only labor-intensive, requires a large workforce, and is inefficient, but it also cannot meet the demands of large-scale, rapid production. Summary of the Invention

[0005] In order to overcome the technical problems of unstable board positioning and easy displacement due to manual placement in existing shearing operations, as well as the high labor intensity and low efficiency of manual loading, this invention provides a shearing machine.

[0006] The shearing machine provided by this invention adopts the following technical solution: A shearing machine includes a frame, an upper blade, a lower blade, and a hydraulic cylinder. The upper blade is connected to the hydraulic cylinder, the hydraulic cylinder is connected to the frame, and the lower blade is connected to the frame. The frame is connected to a mounting device, which includes a first mounting component and a second mounting component. The first mounting component is connected to the frame, and the second mounting component is movably connected to the frame, allowing for adjustable spacing between the first and second mounting components. The frame is also connected to a feeding device, located between the first and second mounting components, for pushing material towards the upper blade. A baffle plate is connected to the frame for cutting the material to a preset length.

[0007] By adopting the above technical solution, the upper blade is driven by a hydraulic cylinder to move, and the lower blade is used to cut the material; the distance between the first and second mounting components of the mounting device is adjustable to accommodate materials of different sizes; the feeding device can push the material to the upper blade for processing; the baffle plate can ensure that the material is cut to a preset length.

[0008] Preferably, the first mounting component includes a first base plate, a first ball bearing, and a first limiting plate. The first base plate is fixedly connected to the frame, the first ball bearing is connected to the first base plate via a first mounting seat, and the first limiting plate is connected to the first base plate.

[0009] By adopting the above technical solution, the first base plate of the first mounting component is fixedly connected to the frame, providing stable support for other components; the first ball is connected to the first base plate through the first mounting seat, which can reduce the friction of the material during placement and facilitate the movement of the material; the first limiting plate is connected to the first base plate, which can limit the material and prevent the material from deviating.

[0010] Preferably, the second mounting assembly includes a second base plate, a second ball bearing, and a second limiting plate. A guide groove is provided on the frame. A sliding plate is fixedly connected to one end of the second base plate. The sliding plate is slidably connected to the frame. A fixing bolt is threaded onto the sliding plate. The fixing bolt can selectively abut against the frame. The second ball bearing is connected to the second base plate through a second mounting seat. The second limiting plate is slidably connected to the second base plate. The second limiting plate and the first limiting plate cooperate to limit the material on both sides.

[0011] By adopting the above technical solution, the second base plate slides and engages with the guide groove on the frame, enabling the second mounting component to move smoothly relative to the first mounting component. With the locking and fixing of bolts, it can quickly and reliably adapt to materials of different widths. At the same time, the second limiting plate works in conjunction with the first limiting plate to form an effective clamping and limiting from both sides of the material, effectively preventing the material from shifting laterally during the shearing process and ensuring the perpendicularity and dimensional consistency of the sheared section.

[0012] Preferably, the second limiting plate is connected to a movable device, which includes a movable frame, a return spring, a rotating shaft, and a cam. The movable frame is fixedly connected to the slide plate, and the second limiting plate is slidably connected to the movable frame. One end of the return spring is connected to the frame, and the other end is connected to the second limiting plate. Both ends of the rotating shaft are rotatably connected to the movable frame. The cam is sleeved on the rotating shaft and fixedly connected to it. The cam is connected to the second limiting plate.

[0013] By adopting the above technical solution, the rotating shaft drives the cam to rotate, and the cam drives the second limiting plate to move. Combined with the guiding and resetting functions of the telescopic rod and the return spring, the elastic and adjustable movement of the second limiting plate is achieved. This flexible limiting method can not only quickly adapt to changes in material width, but also provide stable clamping force within the cam's stroke range, avoiding material deformation or feeding jams caused by excessively tight rigid clamping, thus improving the smoothness and safety of equipment operation.

[0014] Preferably, the feeding device includes a frame, a drive main wheel, a first shaft, an auxiliary wheel, a second shaft, a pusher belt, a pusher block, and a first motor. The frame is fixedly connected to the machine frame. The drive main wheel is rotatably connected to the frame via the second shaft. The auxiliary wheel is rotatably connected to the frame via the second shaft. The pusher belt is sleeved on the drive main wheel and the auxiliary wheel and cooperates with them. The pusher block is fixedly connected to the pusher belt. The drive shaft of the first motor is fixedly connected to the first shaft.

[0015] By adopting the above technical solution, the first motor drives the first shaft to rotate, which in turn drives the main drive wheel to rotate. This, in conjunction with the auxiliary wheel, ensures the smooth operation of the pusher belt. The pusher block, fixed to the pusher belt, moves with the belt, directly pushing the material towards the upper blade. This structure achieves mechanized continuous feeding of materials, with a long pushing stroke and stable thrust. Furthermore, the pusher block automatically cycles and resets as the pusher belt rotates, ensuring the continuity and efficiency of the feeding process.

[0016] Preferably, the frame is connected to a clamping device, which includes a top plate, multiple sets of clamping components, and a lifting module. The top plate is connected to the lifting module. The clamping components include a fixed rod, a sliding rod, a clamping spring, and a clamping block. The fixed rod is fixedly connected to the top plate. The sliding rod is sleeved on the fixed rod and slidably connected to it. The clamping spring is sleeved outside the sliding rod. One end of the clamping spring is connected to the top plate, and the other end is connected to the clamping block. The clamping block is fixedly connected to the end of the sliding rod away from the top plate.

[0017] By adopting the above technical solution, the lifting module drives the top plate to press down, and the fixed rod and sliding rod slide together, so that the clamping block contacts the material surface first, and provides adaptive clamping force under the elastic force of the clamping spring. This elastic clamping structure can apply stable pressure to the material before shearing without damaging the surface, effectively suppressing the vibration and warping of the material during shearing, ensuring a smooth and flat sheared section. At the same time, the spring buffer avoids hard impact on the blade or material due to excessive downward pressure, ensuring stable operation of the shearing machine and achieving precise cutting of the material to the preset length.

[0018] Preferably, the lifting module includes a first lifting component, a second lifting component, a synchronous shaft, a drive motor, a first gear, and a second gear. The first lifting component and the second lifting component are respectively disposed on both sides of the top plate. The synchronous shaft passes through the frame, and its two ends are respectively connected to the adjacent first lifting component or second lifting component. The drive shaft of the drive motor is fixedly connected to the first gear. The second gear is sleeved on the synchronous shaft and meshes with the first gear. The first lifting component and the second lifting component have the same structure, each including a turntable, a first connecting rod, a second connecting rod, and a fixed guide sleeve. The turntable is fixedly connected to the synchronous shaft. One end of the first connecting rod is eccentrically rotatably connected to the turntable. The second connecting rod is rotatably connected to the other end of the first connecting rod. The fixed guide sleeve is fixedly connected to the frame. The second connecting rod passes through the fixed guide sleeve and slides with the fixed guide sleeve.

[0019] By adopting the above technical solution, the drive motor simultaneously drives the first and second lifting components via a synchronous shaft. The eccentric rotation of the turntable causes the first and second connecting rods to slide vertically back and forth within the fixed guide sleeve, thereby driving the synchronous lifting and lowering of both sides of the top plate. This linkage mechanism has a compact structure, high transmission rigidity, and ensures absolute synchronization at both ends of the top plate through the synchronous shaft, effectively preventing the top plate from tilting due to asynchronous lifting on both sides, and ensuring uniform pressure distribution of the pressing device across the entire pressing surface.

[0020] Preferably, a linkage device is provided between the lifting module and the movable device. The linkage device includes a sleeve, a protrusion, a worm gear, a worm, a synchronous shift rod, and a rotating sleeve. The sleeve is fitted onto the synchronous shaft, which has a slot. The protrusion is located in the slot and slidably connected to it. The protrusion is fixedly connected to the sleeve. The worm gear is fitted onto the sleeve, and the worm meshes with it. The worm is fixedly connected to the rotating shaft. One end of the synchronous shift rod is fixedly connected to the moving frame of the movable device, and the other end is fixedly connected to the rotating sleeve. The rotating sleeve is fitted onto the synchronous shaft and rotatably connected to the sleeve.

[0021] By adopting the above technical solution, the sleeve achieves a sliding connection between the protrusion and the groove on the synchronous shaft, allowing it to rotate under the drive of the synchronous shaft and slide axially with the synchronous shift rod. The rotating sleeve is fixed to the moving frame, and the rotational power of the synchronous shaft is precisely transmitted to the rotating shaft through a worm gear. This linkage device ingeniously converts the lifting power of the pressing action into the clamping power of the lateral limiting action, realizing the mechanical linkage of pressing and lateral pushing. It eliminates the need for an additional drive source, reduces manufacturing costs, and ensures a high degree of coordination and consistency between the two actions in terms of timing.

[0022] Preferably, the baffle plate is connected to an adjustment device, which includes a first bracket, a second bracket, a lead screw, a guide rod, and a handwheel. The first bracket and the second bracket are both connected to the machine frame. The lead screw is rotatably connected to the first bracket. The guide rod is fixedly connected to the second bracket. The handwheel is fixedly connected to one end of the lead screw. The baffle plate is sleeved on the lead screw and the guide rod.

[0023] By adopting the above technical solution, the shearing machine has the function of cutting materials to a preset length. Furthermore, through the adjustment device connected to the baffle plate, turning the handwheel can rotate the lead screw, which in turn moves the baffle plate sleeved on the lead screw and guide rod, thereby facilitating and flexibly adjusting the position of the baffle plate to achieve the cutting of materials of different preset lengths.

[0024] Preferably, it also includes a feeding device, which includes a material rack, conveying rollers, a second motor and a synchronization component. Multiple conveying rollers are arranged in parallel and are all rotatably connected to the material rack. The second motor is fixedly connected to the material rack. Any one of the conveying rollers is fixedly connected to the drive shaft of the second motor. A set of synchronization components is connected between each pair of adjacent conveying rollers.

[0025] By adopting the above technical solution, the second motor drives one of the conveyor rollers to rotate, and through multiple sets of synchronization components, the power is synchronously transmitted to the other parallel conveyor rollers, achieving synchronous and unidirectional rotation of all conveyor rollers. This structure can smoothly and quickly transport the material after shearing out of the shearing area, avoiding material accumulation or jamming at the discharge port, effectively connecting the shearing and subsequent collection processes, and further improving the automated continuous operation capability of the entire production line.

[0026] In summary, the present invention has the following beneficial effects: 1. The distance between the first and second placement components of the placement device is adjustable, and the two components work together to limit the material on both sides, ensuring the accuracy and stability of the material placement, avoiding the displacement of the plate during the cutting process, and improving the cutting precision and quality; 2. The feeding device can push the material towards the upper blade, replacing manual feeding, reducing labor intensity, reducing manpower input, improving feeding efficiency, and adapting to the needs of large-scale rapid production; 3. The baffle plate is used to cut materials to a preset length, avoiding the need for manual measurement and marking of the cutting length of the sheet material, simplifying the operation process, reducing errors, and meeting the requirements of high-precision cutting.

[0038] This application mainly uses a frame 1 combined with various devices to achieve efficient shearing, thereby improving the efficiency and accuracy of shearing operations. The following is a further detailed description of this application.

[0039] The shearing machine provided in this application embodiment refers to... Figure 1 and Figure 2 The system includes a frame 1, an upper blade 11, a lower blade 12, a hydraulic cylinder 13, a mounting device 2, a feeding device 4, a baffle plate 7, and a clamping device 5. The upper blade 11 is fixedly connected to the hydraulic cylinder 13, which is in turn fixedly connected to the frame 1. The lower blade 12 is also fixedly connected to the frame 1. The hydraulic cylinder 13 drives the upper blade 11 and lower blade 12 to perform shearing operations, improving the dynamic stability and efficiency of the shearing process. The frame 1 is connected to the mounting device 2, which includes an adjustable first mounting component 21 and a second mounting component 22, accommodating materials of different widths and enhancing the equipment's versatility. The feeding device 4 is located between the first and second mounting components 21 and 22, pushing materials closer to the upper blade 11 for automated feeding and reduced manual labor. The baffle plate 7 has an L-shaped cross-section and is connected to the frame 1 via an adjusting device 8, enabling cutting of materials to a preset length and improving cutting accuracy. The clamping device 5 clamps the material to prevent displacement during cutting.

[0040] Reference Figure 2 The first mounting assembly 21 includes a first base plate 211, a first ball bearing 212, and a first limiting plate 213. The first base plate 211 is made of heavy metal and is a rectangular flat plate. It is fixedly connected to the frame 1 by welding or bolts to ensure a secure connection. The first ball bearing 212 is connected to the first base plate 211 via a first mounting seat. The first mounting seat is typically a circular metal seat with grooves inside for the first ball bearing 212 to roll within. The first ball bearing 212 is embedded in these grooves and can roll flexibly. The first limiting plate 213 is fixedly connected to the first base plate 211, and the two are perpendicularly arranged to limit the movement of material on one side.

[0041] The first base plate 211 provides the mounting foundation and support structure for the first ball bearing 212 and the first limiting plate 213. The first ball bearing 212 allows the material to slide more smoothly during placement, reducing friction and improving the efficiency and flexibility of material placement. The first limiting plate 213 ensures that one side of the material can be accurately limited, facilitating subsequent cutting operations. The three components work together to improve the accuracy and stability of material placement.

[0042] Reference Figure 1 and Figure 3 The second mounting component 22 includes a second base plate 221, a second ball bearing 222, and a second limiting plate 223. A guide groove 101 is provided on the frame 1, which is typically a trapezoidal cross-section groove. A sliding plate 102, typically a metal plate, is fixedly connected to one end of the second base plate 221 and welded to it. The sliding plate 102 is slidably connected to the guide groove 101 of the frame 1, allowing the second base plate 221 to move smoothly along the guide groove 101. A fixing bolt 1021 is also threaded onto the sliding plate 102. When the fixing bolt 1021 is tightened, it abuts against the frame 1, thus fixing the position of the second base plate 221. When the fixing bolt 1021 is loosened, the second base plate 221 can slide freely, thereby adjusting the distance between the first mounting component 21 and the second mounting component 22.

[0043] Reference Figure 1 and Figure 3 The second ball bearing 222 is connected to the second base plate 221 via a second mounting seat. The structure of the second mounting seat is similar to that of the first mounting seat, providing space for the installation and rolling of the second ball bearing 222. The second limiting plate 223 is slidably connected to the second base plate 221. The second limiting plate 223 cooperates with the first limiting plate 213 to limit the material from both sides, ensuring that the material does not sway left and right during the cutting process.

[0044] The second base plate 221 adjusts its position by sliding the slide plate 102 within the guide groove 101, thereby changing the distance between it and the first mounting component 21 to accommodate materials of different widths. The second ball bearing 222 reduces the resistance of the material sliding on the second base plate 221, facilitating the placement and movement of the material. The second limiting plate 223 works together with the first limiting plate 213 to ensure that the material is accurately limited on both sides, guaranteeing the precision of the cutting operation.

[0045] Reference Figure 3The second limiting plate 223 is connected to a movable device 3, which includes a movable frame 31, a return spring 32, a rotating shaft 33, and a cam 34. The movable frame 31 is fixedly connected to the slide plate 102 and is a box-shaped structure with its opening facing the second base plate 221. The second limiting plate 223 is located inside the movable frame 31 and is slidably connected to the inner wall of the movable frame 31. One end of the return spring 32 is connected to the frame 1, and the other end is connected to the second limiting plate 223. At least one return spring 32 is provided. Both ends of the rotating shaft 33 are rotatably connected to the movable frame 31. The cam 34 is sleeved on the rotating shaft 33 and fixedly connected to the rotating shaft 33. The cam 34 abuts against the second limiting plate 223. The return spring 32 remains in a stretched state.

[0046] Reference Figure 1 and Figure 4 The feeding device 4 includes a frame 41, a drive main wheel 42, a first shaft 43, an auxiliary wheel 44, a second shaft 45, a pusher belt 46, a pusher block 47, and a first motor 48. The frame 41 includes two vertical plates, which are fixedly connected to the machine frame 1 by welding or bolts, providing support for other components. The drive main wheel 42 is rotatably connected to the frame 41 via the second shaft 45. The auxiliary wheel 44 is rotatably connected to the frame 41 via the second shaft 45, and the auxiliary wheel 44 and the drive main wheel 42 are positioned parallel to each other. The pusher belt 46 is fitted onto the drive main wheel 42 and the auxiliary wheel 44, and engages with them through friction. When the drive main wheel 42 rotates, it drives the pusher belt 46 to circulate.

[0047] The pusher block 47 is fixedly connected to the pusher belt 46 by welding or bolts, and moves with the pusher belt 46 to push the material forward. The drive shaft of the first motor 48 is fixedly connected to the first shaft 43. When the first motor 48 starts, it transmits power to the drive main wheel 42 through the first shaft 43, causing the drive main wheel 42 to rotate.

[0048] The frame 41 provides a stable support structure for the entire feeding device 4. The drive main wheel 42, auxiliary wheel 44 and pusher belt 46 form a transmission system. The pusher block 47 is on the pusher belt 46. With the movement of the pusher belt 46, it pushes the material towards the upward blade 11, realizing automated feeding, improving feeding efficiency and reducing manual labor intensity.

[0049] Reference Figure 3 , Figure 5 and Figure 6The clamping device 5 includes a top plate 51, multiple clamping assemblies 52, and a lifting module. The top plate 51 is a metal plate, horizontally positioned, and connected to the lifting module, moving up and down via the lifting module's drive. Each clamping assembly 52 includes a fixed rod 521, a sliding rod 522, a clamping spring 523, and a clamping block 524. The fixed rod 521 is fixedly connected to the top plate 51, and the sliding rod 522 is sleeved on and slidably connected to the fixed rod 521. The clamping spring 523 is sleeved outside the sliding rod 522, located between the top plate 51 and the clamping block 524, with one end abutting against the top plate 51 and the other end abutting against the clamping block 524. The clamping block 524 is typically a metal block, fixedly connected to the end of the sliding rod 522 furthest from the top plate 51. When the top plate 51 descends, the clamping spring 523 is compressed, and the clamping block 524 exerts a clamping force on the material, preventing material displacement during cutting.

[0050] The top plate 51 moves up and down under the action of the lifting module, driving the clamping assembly 52 to move together. The fixed rod 521 provides a sliding track for the sliding rod 522. The clamping spring 523 is compressed when the top plate 51 descends, generating elastic force. The elastic force is applied to the material through the clamping block 524 to achieve reliable clamping of the material and ensure the accuracy of the cutting operation.

[0051] Reference Figure 3 , Figure 5 and Figure 6 The lifting module includes a first lifting assembly 53, a second lifting assembly 54, a synchronous shaft 55, a drive motor 56, a first gear 57, and a second gear 58. The first lifting assembly 53 and the second lifting assembly 54 are respectively located on both sides of the top plate 51. The synchronous shaft 55 passes through the frame 1, and its two ends are respectively connected to the adjacent first lifting assembly 53 or second lifting assembly 54. The drive shaft of the drive motor 56 is fixedly connected to the first gear 57, and the second gear 58 is sleeved on the synchronous shaft 55, meshing with the first gear 57.

[0052] When in use, the drive motor 56 starts, driving the synchronous shaft 55 to rotate. The synchronous shaft 55 transmits power to the first lifting component 53 and the second lifting component 54, so that the two work synchronously.

[0053] Reference Figure 3 and Figure 5The first lifting assembly 53 and the second lifting assembly 54 have the same structure, both including a turntable 531, a first connecting rod 532, a second connecting rod 533, and a fixed guide sleeve 534. The turntable 531 is fixedly connected to the synchronous shaft 55 and rotates together with the synchronous shaft 55. One end of the first connecting rod 532 is eccentrically rotatably connected to the turntable 531, and the first connecting rod 532 will oscillate in a circular motion when the turntable 531 rotates. The other end of the second connecting rod 533 is rotatably connected to the first connecting rod 532. The fixed guide sleeve 534 is fixedly connected to the frame 1, and the second connecting rod 533 passes through the fixed guide sleeve 534 and slides in cooperation with the fixed guide sleeve 534. When the turntable 531 rotates, the first connecting rod 532 drives the second connecting rod 533 to slide up and down within the fixed guide sleeve 534, thereby realizing the lifting and lowering of the top plate 51.

[0054] The rotation of turntable 531 is converted into the vertical linear motion of the second link 533 through the linkage mechanism, so as to realize the stable lifting and lowering of top plate 51, and then drive the pressing device 5 to press and release the material.

[0055] Reference Figure 5 and Figure 7 A linkage device 6 is provided between the rotating shaft 33 and the synchronous shaft 55. The linkage device 6 includes a sleeve 61, a protrusion 62, a worm gear 63, a worm 64, a synchronous shift rod 65, and a rotating sleeve 66. The sleeve 61 is sleeved on the synchronous shaft 55, and a groove 551 is provided on the synchronous shaft 55. The protrusion 62 is located in the groove 551 and is slidably connected to the groove 551. The protrusion 62 is fixedly connected to the sleeve 61. In this way, the sleeve 61 can rotate with the synchronous shaft 55 and can also slide axially on the synchronous shaft 55.

[0056] A worm gear 63 is sleeved on and fixedly connected to a sleeve 61. A worm 64 meshes with the worm gear 63. When the worm gear 63 rotates, it drives the worm 64 to rotate. The worm 64 is fixedly connected to the rotating shaft 33 of the movable device 3, thereby transmitting power to the movable device 3. One end of the synchronous shift rod 65 is fixedly connected to the moving frame 31 of the movable device 3, and the other end is fixedly connected to the rotating sleeve 66. The rotating sleeve 66 is sleeved on the synchronous shaft 55 and rotatably connected to the sleeve 61.

[0057] When the synchronous shaft 55 rotates, it drives the sleeve 61 to rotate, which in turn drives the worm gear 63 to rotate. The worm gear 63, through meshing with the worm 64, causes the worm 64 to rotate, transmitting power to the rotating shaft 33 of the movable device 3, thus realizing the linkage between the lifting module and the movable device 3. The synchronous moving rod 65 and the rotating sleeve 66 ensure the synchronous movement and stable operation of the movable device 3 during the linkage process. When the pressing component 52 comes into contact with the material to the preset pressure value, the movable device 3 pushes the second limit plate 223 to press against the material.

[0058] Reference Figure 2The baffle plate 7 is connected to an adjusting device 8, which includes a first bracket 81, a second bracket 82, a lead screw 83, a guide rod 84, and a handwheel 85. The first bracket 81 and the second bracket 82 are both welded or bolted to the frame 1 and are located at opposite ends of the baffle plate 7. The lead screw 83 is rotatably connected to the first bracket 81, and the guide rod 84 is fixedly connected to the second bracket 82, serving a guiding function. The baffle plate 7 is sleeved on the lead screw 83 and the guide rod 84, threadedly connected to the lead screw 83 and slidably connected to the guide rod 84.

[0059] The first bracket 81 and the second bracket 82 provide a stable support structure for the lead screw 83 and the guide rod 84. The handwheel 85 is fixedly connected to one end of the lead screw 83. When the handwheel 85 is turned, the lead screw 83 will rotate, and the baffle plate 7 will move linearly along the guide rod 84, thereby adjusting the position of the baffle plate 7 and accurately moving it to the required position, so as to conveniently and quickly adjust the cutting length of the material.

[0060] Reference Figure 1 The unloading side of the frame 1 is equipped with a feeding device 9, which includes a material rack 91, conveying rollers 92, a second motor 93, and a synchronization assembly 94. The material rack 91 is typically a metal frame structure that provides support for other components. Multiple conveying rollers 92 are arranged horizontally and parallel to each other, and are all rotatably connected to the material rack 91 via bearings. The second motor 93 is fixedly connected to the material rack 91, and any one of the conveying rollers 92 is fixedly connected to the drive shaft of the second motor 93. When the second motor 93 starts, it drives the conveying roller 92 connected to it to rotate. A set of synchronization assemblies 94 is connected between each pair of adjacent conveying rollers 92. The synchronization assembly 94 can be a synchronous belt, synchronous chain, etc., used to ensure that adjacent conveying rollers 92 rotate synchronously and convey the cut material out.

[0061] The material rack 91 provides a mounting base and support structure for the conveyor rollers 92, the second motor 93, and the synchronization assembly 94. The second motor 93 provides power, and the synchronization assembly 94 enables multiple conveyor rollers 92 to rotate synchronously, achieving rapid unloading of the cut material and improving the continuity of the operation process.

[0062] The implementation principle of this embodiment is as follows: This shearing machine integrates multiple functional devices, which cooperate with each other to realize the entire process of material placement, feeding, cutting length control, clamping, and unloading. The adjustable placement device 2 adapts to materials of different widths, the feeding device 4 achieves automated feeding, the clamping device 5 ensures material stability during cutting, the adjusting device 8 precisely controls the cutting length, and the unloading device 9 achieves rapid unloading. Compared with traditional shearing machines, this greatly improves the efficiency and accuracy of shearing operations, reduces manual labor intensity, and enhances the versatility and practicality of the equipment. The embodiments described in this specific implementation are preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made according to the structure, shape, and principle of the present invention should be covered within the scope of protection of the present invention.
