Description

Technical Field

[0001] This application relates to the technical field of grid bridge processing equipment, and specifically relates to an automatic net plate cutting equipment. Background Technique

[0002] When laying cables, communication optical cables or other slender pipes, grid bridges are usually used for support and protection. The existing grid bridges are generally of a grid-like structure with a "C" - shaped structure, and the inside of the "C" - shaped structure is used for laying cables, communication optical cables or other slender pipes.

[0003] Currently, when processing a grid bridge with a "C" - shaped structure, it is usually necessary to first use an automatic welding equipment to automatically weld multiple transverse ribs and multiple longitudinal ribs to form a grid - like structure (i.e., a net plate); then manually lift the whole net plate to the cutting station, and according to the model of the grid bridge to be processed, manually cut a net plate with a suitable width on the whole net plate; finally, the cut net plate is transported to a bending machine for bending to manufacture the grid bridge.

[0004] However, the above - mentioned processing method has the following defects: 1. Since the size of the net plate formed by automatic welding is generally large, at least two workers are required to carry the net plate to the cutting station, which is difficult to carry, time - consuming and labor - intensive; 2. The efficiency of manual cutting is low, which prolongs the processing cycle of the grid bridge; at the same time, it is difficult to control the dimensional accuracy of manual cutting, which increases the difficulty of fixing the net plate during the bending operation.

[0005] Therefore, how to design an automatic net plate cutting equipment to overcome the above - mentioned deficiencies is an urgent problem to be solved by those skilled in the art. Summary of the Invention

[0006] An object of this application is to provide an automatic net plate cutting equipment with high automation, strong versatility, high working efficiency, and high cutting dimensional accuracy.

[0007] To achieve the above objectives, the technical solution adopted in this application is as follows: an automatic stencil cutting device, comprising a frame, a traction mechanism, a pressing mechanism, a cutting mechanism, and a moving track; the moving track is disposed on the right side of an automatic welding device, which can transport the welded stencil body from left to right to the moving track; the frame is disposed on the right side of the moving track, and a worktable aligned with the moving track is provided on the frame; the traction mechanism, the pressing mechanism, and the cutting mechanism are disposed on the frame; the traction mechanism is used to traction the stencil body on the moving track to move to the right until the right end of the stencil body moves to the right side of the worktable, the pressing mechanism is used to press the stencil body against the worktable, and the cutting mechanism is used to cut off the portion of the stencil body located on the right side of the worktable.

[0008] Preferably, the traction mechanism includes a horizontal guide rail, a sliding seat, and a pusher plate; the horizontal guide rail is arranged on the frame in a left-right direction, and the sliding seat is slidably arranged on the horizontal guide rail; the pusher plate is rotatably arranged on the sliding seat, and the pusher plate is provided with a slot; when the slot rotates with the pusher plate to engage with the longitudinal rib of the mesh plate body, the mesh plate body slides synchronously with the sliding seat. Its advantage is that by controlling the rotation of the pusher plate until the slot rotates with the pusher plate to engage with the longitudinal rib, and then controlling the sliding seat to move to the right, the mesh plate body can be driven to slide synchronously to the right with the pusher plate (i.e., the sliding seat); of course, when a program error occurs or it is necessary to shorten the width of the mesh plate body for cutting, the mesh plate body can also be driven to move to the left through the sliding seat. When the slot rotates with the pusher plate to separate from the longitudinal rib, the force exerted by the pusher plate on the longitudinal rib (i.e., the mesh plate body) disappears, meaning the mesh plate body does not move with the sliding seat. At this time, the sliding seat is controlled to slide to the left, and the slot is controlled to re-engage with the longitudinal rib to push the longer mesh plate body in the left-right direction to continue moving to the right.

[0009] Preferably, the slot is an inverted V-shaped structure. Its advantages are: the lower end of this type of slot is wider, ensuring that even with some error between the slot and the longitudinal rib, the slot can still engage properly when the pusher plate rotates to engage with the longitudinal rib. This prevents machine malfunctions due to the slot failing to engage properly with the longitudinal rib, thus improving the stability of automated operation. Furthermore, because the width of the slot gradually decreases from bottom to top, it limits the relative displacement between the longitudinal rib and the slot in the left-right direction after engagement, ensuring the accuracy of the pusher plate in pushing the longitudinal rib (i.e., the mesh plate body) to the right.

[0010] Preferably, the traction mechanism further includes a fixed shaft and a drive cylinder; the fixed shaft is rotatably mounted on the sliding seat and is arranged along the front-to-back direction; the pusher plate is mounted on the fixed shaft; one end of the drive cylinder is hinged to the sliding seat, and the other end of the drive cylinder is hinged to the pusher plate. Its advantages are: by controlling the extension and retraction of the drive cylinder, the pusher plate can be driven to rotate, which is easy to operate; and the drive cylinder's action is rapid, enabling quick engagement and disengagement between the slot and the longitudinal rib.

[0011] Preferably, the traction mechanism further includes a lead screw and a drive motor; the lead screw is rotatably mounted on the horizontal guide rail, and the axis of the lead screw is arranged in the left-right direction; the drive motor is fixed to the frame, and the output shaft of the drive motor is connected to the lead screw; a threaded hole is provided through the sliding seat in the left-right direction, and the threaded hole is threadedly connected to the lead screw. Its advantages are: by controlling the start, stop, and forward / reverse rotation of the drive motor, the sliding seat can be driven to slide in the left-right direction via the lead screw, making operation simple and allowing for precise control of the sliding distance of the sliding seat.

[0012] Preferably, the pressing mechanism includes a telescopic component, a buffer component, and a pressure plate, with the pressure plate located directly above the worktable. The telescopic component is mounted vertically on the frame, and its lower end is connected to the upper end of the pressure plate via the buffer component. Its advantages are: by controlling the telescopic component's extension and retraction, the pressure plate can be driven to move up and down, making operation simple; when the pressure plate moves downwards to contact the mesh plate body, it presses the mesh plate body firmly onto the worktable, allowing the mesh plate body to shift or its left end to lift during the cutting process; when the pressure plate moves upwards to separate from the mesh plate body, the pressing effect on the mesh plate body is released, allowing the traction mechanism to pull the mesh plate body to move. Furthermore, under the action of the buffer component, the telescopic force of the telescopic component will not directly act on the mesh plate body, preventing significant impact on the telescopic component itself and the mesh plate body, thereby extending the service life of the telescopic component and avoiding damage to the mesh plate body.

[0013] Preferably, the buffer assembly includes a sleeve, a core rod, and a spring; the upper end of the sleeve is fixed to the lower end of the telescopic assembly, and the lower end of the sleeve has an open structure; the upper end of the core rod is slidably connected to the inside of the sleeve, and the lower end of the core rod is fixed to the upper end of the pressure plate; the spring is sleeved on the outside of the core rod, the upper end of the spring is fixed to the lower end of the sleeve, and the lower end of the spring is fixed to the upper end of the pressure plate. Its advantages are: when the telescopic assembly extends, the sleeve presses down on the pressure plate through the spring, thereby pressing the mesh plate body tightly onto the worktable; at this time, the upper end of the core rod can slide upward relative to the sleeve, that is, the distance between the pressure plate and the sleeve is shortened, thus providing a buffering effect; when the telescopic assembly shortens, the sleeve pulls up the pressure plate through the spring, thereby separating the pressure plate from the mesh plate body.

[0014] Preferably, the pressure plate has an arc-shaped structure, with its inner arc surface facing upwards. The advantage is that, since the mesh plate body is a mesh structure formed by welding multiple longitudinal and transverse ribs, meaning the mesh plate body has numerous square mesh holes, and since a single longitudinal or transverse rib is prone to bending and deformation, when the pressure plate has an arc-shaped structure and its inner arc surface faces upwards, it effectively prevents the pressure plate from getting stuck in the square mesh holes. Otherwise, if the pressure plate gets stuck in the square mesh holes, when the telescopic component shortens, the pressure plate will cause the mesh plate body to move upwards, leading to machine malfunction.

[0015] Preferably, the clamping mechanism further includes a guide plate, which is fixed to the frame and located to the left of the pressure plate. A gap is formed between the right end of the guide plate and the worktable for the mesh plate body to pass through. The left end of the guide plate is bent upwards to form a guide slope or guide arc surface. The advantage is that the guide slope or guide arc surface effectively guides the mesh plate body onto the worktable (i.e., between the worktable and the pressure plate). Otherwise, if the right end of the mesh plate body tilts upwards, it may easily abut against the pressure plate or a structure above the pressure plate, causing machine malfunction.

[0016] Preferably, the cutting mechanism includes a cutter, a mounting frame, and two swing arms. The two swing arms are symmetrically arranged on the right side of the worktable in a front-to-back direction. The left ends of the two swing arms are connected by the mounting frame, and the right ends of the two swing arms are coaxially and rotatably mounted on the frame. The rotation axes of the two swing arms are arranged in a front-to-back direction. The cutter is detachably mounted on the mounting frame in a front-to-back direction. When the cutter rotates counterclockwise with the swing arms, it can cut off the portion of the mesh plate body located on the right side of the worktable. Its advantage is that the cutting operation can be achieved by controlling the rotation of the two swing arms, making operation simple.

[0017] Preferably, the angle α formed between the blade of the cutter and the upper surface of the worktable is 0° to 5°. The advantage is that during cutting, under the action of the angle α, the cutter will not cut all the transverse ribs simultaneously, but will cut them sequentially from back to front (or from front to back). Compared to cutting all the transverse ribs simultaneously, this cutting method reduces the driving force on the cutter and prevents the cut mesh body from falling directly down.

[0018] Preferably, the cutting mechanism further includes a hydraulic cylinder, one end of which is hinged to the frame, and the other end of which is hinged to the mounting bracket. Its advantages are: by controlling the extension and retraction of the hydraulic cylinder, the two swing arms can be rotated simultaneously via the mounting bracket, making operation simple; and the hydraulic cylinder provides stable and reliable power, which helps improve the stability of the cutting process.

[0019] Compared with the prior art, the beneficial effects of this application are: (1) By setting the moving track on the right side of the automatic welding equipment, the automatic welding equipment automatically transports the welded mesh plate body from left to right to the moving track, and the traction mechanism set on the frame automatically pulls the mesh plate body on the moving track to the right, so that the mesh plate body does not need to be manually moved, which reduces the workload of workers and improves work efficiency.

[0020] (2) When the right end of the mesh plate body moves to the right side of the worktable, the clamping mechanism presses the mesh plate body onto the worktable to prevent the left end of the mesh plate body from lifting or the mesh plate body from shifting during cutting, thus ensuring cutting accuracy and improving the safety of the cutting process. The cutting mechanism cuts off the portion of the mesh plate body located on the right side of the worktable, and the cut mesh plate body automatically falls to the right side of the worktable under gravity for easy collection. After one cutting is completed, the traction mechanism pulls the mesh plate body on the moving track to continue moving to the right to repeat the cutting operation, resulting in a high degree of automation. By controlling the distance the traction mechanism pulls the mesh plate body to the right, the distance between the right end of the mesh plate body and the worktable can be precisely changed, that is, the width of the cut mesh plate body can be precisely changed, making it highly versatile.

[0037] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0038] In the description of this application, it should be noted that the directional terms such as "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", and "counterclockwise" indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. They should not be construed as limiting the specific protection scope of this application.

[0039] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0040] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.

[0041] Reference Figure 1-5One embodiment of this application provides an automatic stencil cutting device, including a frame 1, a traction mechanism 2, a pressing mechanism 3, a cutting mechanism 4, and a moving track 5. The moving track 5 is located on the right side of an automatic welding equipment 100, allowing the automatic welding equipment 100 to transport the welded stencil body 200 from left to right to the moving track 5. The frame 1 is located on the right side of the moving track 5, and a worktable 11 aligned with the moving track 5 is provided on the frame 1. The traction mechanism 2, the pressing mechanism 3, and the cutting mechanism 4 are located on the frame 1. The traction mechanism 2 is used to traction the stencil body 200 on the moving track 5 to move to the right until the right end of the stencil body 200 moves to the right side of the worktable 11. The pressing mechanism 3 is used to press the stencil body 200 onto the worktable 11, and the cutting mechanism 4 is used to cut off the portion of the stencil body 200 located on the right side of the worktable 11. This application addresses the issue by placing the moving track 5 on the right side of the automatic welding equipment 100. This allows the automatic welding equipment 100 to automatically transport the welded mesh plate body 200 from left to right onto the moving track 5. The traction mechanism 2, mounted on the frame 1, automatically pulls the mesh plate body 200 on the moving track 5 to the right, eliminating the need for manual handling of the mesh plate body 200, thus reducing worker workload and improving efficiency. When the right end of the mesh plate body 200 moves to the right side of the worktable 11, the clamping mechanism 3 presses the mesh plate body 200 firmly onto the worktable 11 to prevent the left end of the mesh plate body 200 from lifting or shifting during cutting, ensuring cutting accuracy and improving the safety of the cutting process. The cutting mechanism 4 cuts off the portion of the mesh plate body 200 located on the right side of the worktable 11. The cut mesh plate body 200 automatically falls to the right side of the worktable 11 under gravity for easy collection. After one cut is completed, the traction mechanism 2 pulls the mesh plate body 200 on the moving track 5 to continue moving to the right to repeat the cutting operation, resulting in a high degree of automation. By controlling the distance the traction mechanism 2 pulls the mesh plate body 200 to the right, the distance between the right end of the mesh plate body 200 and the worktable 11 can be precisely changed, that is, the width of the cut mesh plate body 200 can be precisely changed, making it highly versatile. It should be noted that the automatic welding equipment 100 itself is existing technology, and its specific working principle will not be described in detail here.

[0042] Reference Figure 2-3 as well as Figure 8-10In some embodiments of this application, the traction mechanism 2 includes a horizontal guide rail 21, a sliding seat 22, and a pusher plate 23. The horizontal guide rail 21 is arranged on the frame 1 in the left-right direction, and the sliding seat 22 is slidably arranged on the horizontal guide rail 21. The pusher plate 23 is rotatably arranged on the sliding seat 22, and the pusher plate 23 is provided with a slot 231. When the slot 231 rotates with the pusher plate 23 to engage with the longitudinal rib 201 of the mesh plate body 200, the mesh plate body 200 slides synchronously with the sliding seat 22. By controlling the pusher plate 23 to rotate until the slot 231 rotates with the pusher plate 23 to engage with the longitudinal rib 201, the sliding seat 22 is then controlled to move to the right, thereby driving the mesh plate body 200 to slide synchronously to the right with the pusher plate 23 (i.e., the sliding seat 22). Of course, when a program error occurs or the width of the cutting mesh plate body 200 needs to be shortened, the mesh plate body 200 can also be driven to move to the left by the sliding seat 22. When the slot 231 rotates with the pusher plate 23 until it separates from the longitudinal rib 201, the force exerted by the pusher plate 23 on the longitudinal rib 201 (i.e., the mesh plate body 200) disappears, meaning the mesh plate body 200 does not move with the sliding seat 22. At this time, the sliding seat 22 is controlled to slide to the left, and the slot 231 is controlled to re-engage with the longitudinal rib 201 so that the longer mesh plate body 200 in the left-right direction can continue to move to the right.

[0043] Reference Figure 10 In some embodiments of this application, the slot 231 has an inverted V-shaped structure. This type of slot 231 has a wider lower end. When the slot 231 rotates with the pusher plate 23 to engage with the longitudinal rib 201, even if there is a certain error between the slot 231 and the longitudinal rib 201, it can still ensure that the slot 231 can eventually engage with the longitudinal rib 201, thus avoiding machine malfunctions due to the slot 231 failing to engage properly with the longitudinal rib 201, thereby improving the stability of automated operation. Furthermore, since the width of the slot 231 gradually decreases from bottom to top, when the slot 231 finally engages with the longitudinal rib 201, it can limit the relative displacement between the longitudinal rib 201 and the slot 231 in the left-right direction, ensuring the accuracy of the pusher plate 23 in pushing the longitudinal rib 201 (i.e., the mesh plate body 200) to the right.

[0044] Reference Figure 3 as well as Figure 9 In some embodiments of this application, the traction mechanism 2 further includes a fixed shaft 24 and a drive cylinder 25; the fixed shaft 24 is rotatably mounted on the sliding seat 22 and is arranged in the front-rear direction; the pusher plate 23 is mounted on the fixed shaft 24; one end of the drive cylinder is hinged to the sliding seat 22, and the other end of the drive cylinder is hinged to the pusher plate 23. By controlling the extension and retraction of the drive cylinder 25, the pusher plate 23 can be driven to rotate, which is easy to operate, and the action of the drive cylinder 25 is rapid, which can quickly realize the engagement and disengagement between the slot 231 and the longitudinal rib 201.

[0045] Reference Figure 4 as well as Figure 12-13 In some embodiments of this application, the traction mechanism 2 further includes a lead screw 26 and a drive motor 27. The lead screw 26 is rotatably mounted on a horizontal guide rail 21, and its axis is arranged in the left-right direction. The drive motor 27 is fixed to the frame 1, and its output shaft is connected to the lead screw 26. A threaded hole 221 is provided through the sliding seat 22 in the left-right direction, and the threaded hole 221 is threadedly connected to the lead screw 26. By controlling the start, stop, and forward / reverse rotation of the drive motor 27, the sliding seat 22 can be driven to slide in the left-right direction via the lead screw 26. This method is simple to operate and allows for precise control of the sliding distance of the sliding seat 22. It should be noted that the connection between the output shaft of the drive motor 27 and the lead screw 26 is existing technology; it can be a direct connection or a connection through a transmission mechanism, which will not be described in detail here.

[0046] Reference Figure 4 , Figure 8 as well as Figure 11 In some embodiments of this application, the pressing mechanism 3 includes a telescopic component 31, a buffer component 32, and a pressure plate 33, with the pressure plate 33 located directly above the worktable 11. The telescopic component 31 is disposed on the frame 1 in the vertical direction, and the lower end of the telescopic component 31 is connected to the upper end of the pressure plate 33 through the buffer component 32. By controlling the telescopic component 31, the pressure plate 33 can be driven to move up and down, making operation simple. When the pressure plate 33 moves downward to contact the mesh body 200, it can press the mesh body 200 onto the worktable 11, so that the mesh body 200 can be displaced or the left end of the mesh body 200 can be lifted during the cutting process. When the pressure plate 33 moves upward to separate from the mesh body 200, the pressing effect on the mesh body 200 can be released, so that the traction mechanism 2 can pull the mesh body 200 to move. In addition, under the action of the buffer component 32, the telescopic force of the telescopic component 31 will not act directly on the mesh body 200, thereby preventing a large impact on the telescopic component 31 itself and the mesh body 200, which is conducive to extending the service life of the telescopic component 31 and avoiding damage to the mesh body 200.

[0047] Reference Figure 11In some embodiments of this application, the buffer assembly 32 includes a sleeve 321, a core rod 322, and a spring 323; the upper end of the sleeve 321 is fixed to the lower end of the telescopic assembly 31, and the lower end of the sleeve 321 is an open structure; the upper end of the core rod 322 is slidably connected to the inside of the sleeve 321, and the lower end of the core rod 322 is fixed to the upper end of the pressure plate 33; the spring 323 is sleeved on the outside of the core rod 322, the upper end of the spring 323 is fixed to the lower end of the sleeve 321, and the lower end of the spring 323 is fixed to the upper end of the pressure plate 33. When the telescopic component 31 extends, the sleeve 321 presses down on the pressure plate 33 via the spring 323, thereby pressing the mesh body 200 onto the worktable 11. At this time, the upper end of the core rod 322 can slide upward relative to the sleeve 321, that is, the distance between the pressure plate 33 and the sleeve 321 is shortened, which can play a buffering role. When the telescopic component 31 shortens, the sleeve 321 pulls up the pressure plate 33 via the spring 323, thereby separating the pressure plate 33 from the mesh body 200.

[0048] Reference Figure 4 as well as Figure 12-13 In some embodiments of this application, the pressure plate 33 has an arc-shaped structure, with its inner arc surface facing upwards. Since the mesh body 200 is a mesh structure formed by welding multiple longitudinal ribs 201 and multiple transverse ribs 202, meaning the mesh body 200 has numerous square mesh holes, and since a single longitudinal rib 201 and a single transverse rib 202 are prone to bending and deformation, when the pressure plate 33 has an arc-shaped structure and its inner arc surface faces upwards, it can effectively prevent the pressure plate 33 from getting stuck in the square mesh holes. Otherwise, if the pressure plate 33 gets stuck in the square mesh holes, when the telescopic component 31 shortens, the pressure plate 33 will cause the mesh body 200 to move upwards, thereby causing machine malfunction.

[0049] Reference Figure 4 as well as Figure 11 In some embodiments of this application, the clamping mechanism 3 further includes a guide plate 34, which is fixed to the frame 1 and located to the left of the pressure plate 33. A gap is formed between the right end of the guide plate 34 and the worktable 11 for the mesh plate body 200 to pass through. The left end of the guide plate 34 is bent upward to form a guide arc surface (shown in the figure as a guide arc surface, but it could also be a guide slope). Under the action of the guide slope or guide arc surface, the mesh plate body 200 can be effectively guided onto the worktable 11 (i.e., between the worktable 11 and the pressure plate 33). Otherwise, if the right end of the mesh plate body 200 is tilted upward, the right end of the mesh plate body 200 may easily abut against the pressure plate 33 or the structure above the pressure plate 33, thereby causing machine failure.

[0050] Reference Figure 5 , Figure 8 as well as Figure 11In some embodiments of this application, the cutting mechanism 4 includes a cutter 41, a mounting frame 42, and two swing arms 43. The two swing arms 43 are symmetrically arranged on the right side of the workbench 11 along the front-back direction. The left ends of the two swing arms 43 are connected by the mounting frame 42, and the right ends of the two swing arms 43 are coaxially and rotatably mounted on the frame 1. The rotation axes of the two swing arms 43 are arranged along the front-back direction. The cutter 41 is detachably mounted on the mounting frame 42 along the front-back direction. When the cutter 41 rotates counterclockwise with the swing arms 43, it can cut off the portion of the mesh body 200 located on the right side of the workbench 11. By controlling the rotation of the two swing arms 43, the cutter 41 can be driven to perform the cutting operation, which is easy to operate. It should be noted that the rotatable mounting method between the swing arms 43 and the frame 1 is prior art, for example, as Figure 15 As shown, the swing arm 43 is rotatably mounted on the frame 1 via the rotating shaft 300 and the bearing 400.

[0051] Reference Figure 14 In some embodiments of this application, the included angle α formed between the blade of the cutter 41 and the upper surface of the worktable 11 is 0° to 5°. During cutting, under the action of the included angle α, the cutter 41 will not cut all the transverse ribs 202 at the same time, but will cut all the transverse ribs 202 sequentially from back to front (or from front to back). Compared with cutting all the transverse ribs 202 at the same time, this cutting method can reduce the driving force on the cutter 41 (i.e., the load on the hydraulic cylinder 45); on the other hand, since the mesh plate body 200 is easy to bend, that is, the end that is cut first gradually bends and droops, so that it can be neatly stacked into a stack; otherwise, if it is cut at the same time, the cut mesh plate body 200 will fall directly, making the kinetic energy of the mesh plate body 200 when it lands large, which makes it difficult to stack neatly into a stack and is also easy to wear due to collision. It should be noted that when the included angle α is equal to 0°, the blade of the cutter 41 is parallel to the upper surface of the worktable 11, and the cutting operation can still be achieved; when the included angle α is greater than 5°, the height difference between the front and rear ends of the blade of the cutter 41 is large, the movement range of the cutter 41 is large during cutting, and the cutting efficiency decreases; in summary, the included angle α is preferably 0° to 5°; at the same time, according to experiments, the overall performance is best when the included angle α is 2.5°.

[0052] Reference Figure 8 as well as Figure 11 In some embodiments of this application, the cutting mechanism 4 further includes a hydraulic cylinder 45, one end of which is hinged to the frame 1, and the other end of which is hinged to the mounting bracket 42. By controlling the extension and retraction of the hydraulic cylinder 45, the two swing arms 43 can be driven to rotate simultaneously via the mounting bracket 42. This is easy to operate, and the power of the hydraulic cylinder 45 is stable and reliable, which helps to improve the stability of the cutting process.
