Description

Technical Field

[0001] This application relates to the technical field of processing parts for transportation equipment, and in particular to a cutting and blanking machine for processing crossbeams of transportation equipment. Background Technology

[0002] Crossbeams are typically installed in the frame, skeleton, and body load-bearing structure of transportation equipment. The crossbeams are mainly used to connect the longitudinal components on both sides and to bear the functions of support, connection, and load transfer.

[0003] Existing crossbeam raw material cutting equipment typically includes a conveying mechanism and a cutting mechanism. The conveying mechanism transports the strip-shaped raw material to a predetermined cutting position, and then the cutting blade cuts the crossbeam raw material to a fixed length. For example, Chinese patent document CN222890642U discloses a raw material cutting device for processing the rear crossbeam of an automobile roof. It supports the steel strip with a movable and adjustable stabilizing component and uses a cutting component to cut the steel strip. At the same time, it uses an auxiliary wheel set and a drive wheel set to transport the steel strip, thereby improving the stability of the steel strip transport and cutting process. However, the above technical solutions still have some shortcomings: On the one hand, the feeding and stabilizing support mechanism consists of multiple adjustment components, and the overall structure is relatively complex. When facing crossbeam raw materials of different widths and thicknesses, it is necessary to adjust the corresponding components, which is not convenient to operate and makes it difficult to quickly adapt to crossbeam raw materials of different specifications. On the other hand, the existing equipment mainly relies on the conveying mechanism and local support structure to support the crossbeam raw materials during the cutting process. However, the support range near the cutting point is limited. When the cutting blade presses down on the crossbeam raw materials, local stress concentration is likely to occur at the cutting position, which will cause the crossbeam raw materials to dent or deform near the cutting point, affecting the flatness of the cutting surface and the subsequent processing quality of the crossbeam blank. Summary of the Invention

[0004] This application aims to at least partially address one of the technical problems in the related art.

[0008] In one embodiment of this application, the driving component includes a drive motor, a drive sprocket, a driven sprocket, a chain, and a bidirectional lead screw. The drive motor is mounted on the base plate, the drive sprocket and the driven sprocket are both rotatably mounted on the fixed frame, the driven sprocket is mounted on the bidirectional lead screw, the driven sprocket and the drive sprocket are connected by the chain drive, and the output end of the drive motor passes through the fixed frame and is connected to the drive sprocket.

[0009] In one embodiment of this application, the limiting component includes a slide table, a fixed frame, a limiting slide rod, an auxiliary rod, an abutment plate, and an abutment roller. The slide table is threaded onto the bidirectional lead screw, the fixed frame is mounted on the slide table, the abutment plate is connected to the fixed frame via the auxiliary rod, the limiting slide rod is mounted on the abutment plate, the mounting frame has a sliding hole for the limiting slide rod to slide, and the abutment roller is rotatably mounted on the abutment plate.

[0010] In one embodiment of this application, the cutting assembly includes a hydraulic cylinder, a support frame, and a cutter, wherein the hydraulic cylinder is mounted on the mounting plate, the support frame is mounted on the extended end of the hydraulic cylinder, the cutter is rotatably mounted on the support frame, and the support frame is also used to support the cutting end of the beam during the beam cutting process.

[0011] In one embodiment of this application, the pressing assembly includes a connecting frame, a connecting plate, and a pressing component, wherein the connecting frame is mounted on the support frame, and the pressing component is mounted on the connecting frame via the connecting plate.

[0012] In one embodiment of this application, the pressing component includes a mounting sleeve, a slide cylinder, a sliding plate, a spring, a sleeve rod, a threaded rod, a driven gear, a transmission rod, and a driving gear. The mounting sleeve is disposed on the connecting plate. The slide cylinder is slidably mounted on the mounting sleeve via the sliding plate, and the mounting sleeve has a groove for the sliding plate to slide. A ball bearing is rolled at the bottom end of the slide cylinder. The spring is mounted on the slide cylinder. The sleeve rod is threadedly connected to the mounting sleeve via the threaded rod, and the top end of the spring abuts against the bottom end of the threaded rod. The driven gear is rotatably mounted on the connecting frame, and the threaded rod is slidably connected to the driven gear. The driving gear is rotatably mounted on the connecting frame. The transmission rod is connected to the driving gear, and the driving gear meshes with the driven gear.

[0013] In one embodiment of this application, auxiliary components are installed at the bottom ends of both the linkage plate and the slide table. The auxiliary components include an auxiliary plate and an auxiliary wheel. The auxiliary plate is connected to both the linkage plate and the slide table. The auxiliary wheel is rotatably mounted on the auxiliary plate and abuts against the base plate.

[0014] Compared with the prior art, this application has at least the following beneficial effects: 1. This application uses a limiting component to clamp and limit the crossbeam on the conveyor roller, and uses a bidirectional screw to drive the two side slides to move towards or away from each other, so that the abutment plate and abutment roller can be synchronously adjusted according to the width of the crossbeam, thereby improving the stability of the conveying process of crossbeams of different specifications and simplifying the equipment adjustment operation. By connecting the limiting component to the linkage plate, the limiting component can drive the cutting mechanism to move accordingly while limiting the position of the crossbeam, so that the cutting mechanism can fully contact one side of the crossbeam to be cut, reducing the initial movement stroke of the cutting mechanism before operation.

[0015] 2. This application incorporates a pressing component on the cutting assembly. When the hydraulic cylinder drives the support frame and cutter to cut, the pressing component can simultaneously press and fix the crossbeam, and work with the support frame to support the cutting end. This reduces the shaking, warping, or denting of the crossbeam caused by localized force concentration during the cutting process, improves the flatness of the cut surface and the processing quality of the crossbeam. Furthermore, by incorporating a sliding cylinder, spring, threaded rod, and an adjustment structure consisting of a drive gear and a driven gear in the pressing component, the pressing height and pressing force of the pressing component can be adjusted according to the thickness of the crossbeam. At the same time, the spring provides elastic buffering, ensuring stable contact with the crossbeam during the pressing process and reducing the possibility of damage to the crossbeam surface caused by rigid pressing.

[0016] 3. This application provides ball bearings at the bottom of the slide cylinder, enabling the pressing component to maintain rolling contact with the crossbeam while pressing it. This reduces sliding friction between the pressing structure and the crossbeam during the crossbeam conveying process, thereby balancing the pressing stability and continuous conveying effect of the crossbeam.

[0017] 4. This application provides auxiliary components at the bottom of the linkage plate and the slide table, and uses auxiliary wheels to abut against the base plate to form rolling support, thereby transforming the sliding friction experienced by the linkage plate and the slide table during movement into rolling friction, thereby reducing movement resistance, improving the smoothness of position adjustment of the limit component and the cutting mechanism and the stability during movement, and thus helping to improve the stability of the mechanism operation.

Detailed Implementation

[0021] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0022] The following description, in conjunction with the accompanying drawings, describes a cutting and blanking machine for processing crossbeams of transportation equipment according to an embodiment of this application.

[0023] like Figures 1 to 6 As shown, this embodiment provides a cutting and blanking machine for processing crossbeams of transportation equipment, mainly used for cutting strip-shaped crossbeam raw materials used in transportation equipment to a fixed length. The cutting and blanking machine includes a base plate 1, which serves as the installation foundation for the entire equipment. A conveying mechanism 2, a cutting mechanism 3, and a blanking assembly 4 are sequentially arranged on the base plate along the crossbeam conveying direction, so that the crossbeam can sequentially complete feeding, positioning adjustment, cutting processing, and blanking after cutting.

[0024] In actual processing, the beam to be processed is first placed on the conveying mechanism 2. The conveying mechanism 2 supports and transports the beam through the conveying rollers 22. As the beam moves towards the cutting position, the limiting components 23 clamp it from both sides, ensuring a stable conveying posture. After the beam moves to the predetermined cutting area, the cutting mechanism 3 cuts the beam. Simultaneously, the pressing component 34, which works synchronously with the cutting action, presses the beam, and the support structure provides auxiliary support to the cutting end, thereby reducing deformation caused by concentrated force during the cutting process. After cutting, the cut beam is received and discharged by the unloading component 4 for subsequent collection or transfer.

[0025] In some embodiments of this application, such as Figure 2 As shown, during the loading and conveying process of the crossbeam, the conveying mechanism 2 undertakes the main supporting and conveying functions of the crossbeam. The conveying mechanism 2 includes a mounting frame 21, conveying rollers 22, and a limiting assembly 23. The mounting frame 21 is fixedly mounted on the base plate 1, and multiple conveying rollers 22 are spaced apart along the conveying direction of the crossbeam and rotatably mounted on the mounting frame 21. After the crossbeam is placed on the conveying rollers 22, the crossbeam and the outer circumferential surface of the conveying rollers 22 form rolling contact, thereby enabling it to move along the conveying direction when the conveying rollers 22 rotate. Compared to directly dragging the crossbeam on the fixed platform, using the conveying rollers 22 to support it reduces the frictional resistance experienced by the crossbeam during movement, allowing even longer or heavier crossbeams to move more smoothly towards the area where the cutting mechanism 3 is located.

[0026] To further clarify the above embodiment, in one embodiment of this application, as follows: Figure 3 As shown, since the dimensions of the crossbeams used in different transportation equipment may differ in the width direction, this embodiment utilizes limiting components 23 to adaptively limit the crossbeams. The limiting components 23 are disposed on the base plate 1 and located on both sides of the conveyor roller 22. The limiting components 23 include a fixed frame 231, a driving component 232, and limiting components 233. The fixed frame 231 serves as the mounting base for the driving component 232, which is fixed to the base plate 1. The driving component 232 is mounted on the fixed frame 231 and engages with the limiting components 233 on both sides in a driving manner.

[0027] Specifically, the drive component 232 comprises a drive motor 2321, a drive sprocket 2322, a driven sprocket 2323, a chain 2324, and a double-acting lead screw 2325. The drive motor 2321 is mounted on the base plate 1, and its output end passes through the fixed frame 231 and is connected to the drive sprocket 2322. Both the drive sprocket 2322 and the driven sprocket 2323 are rotatably mounted on the fixed frame 231, and the driven sprocket 2323 is fixedly mounted on the double-acting lead screw 2325. The drive sprocket 2322 and the driven sprocket 2323 are connected by the chain 2324.

[0028] When the positions of the limit switches on both sides need to be adjusted according to the width of the crossbeam, the drive motor 2321 is started. The output end of the drive motor 2321 drives the drive sprocket 2322 to rotate. The drive sprocket 2322 transmits power to the driven sprocket 2323 through the chain 2324, which in turn drives the double-acting screw 2325 to rotate. Since the threads on both sides of the double-acting screw 2325 rotate in opposite directions, the two limit components 233 that cooperate with it can move synchronously towards each other or synchronously away from each other when the double-acting screw 2325 rotates.

[0029] Specifically, such as Figure 3 As shown, the limiting component 233 includes a slide table 2331, a fixed frame 2332, a limiting slide rod 2333, an auxiliary rod 2334, an abutment plate 2335, and an abutment roller 2336. The slide table 2331 is threaded onto the corresponding threaded sections of the bidirectional lead screw 2325, and the fixed frame 2332 is mounted on the slide table 2331. The abutment plate 2335 is connected to the fixed frame 2332 via the auxiliary rod 2334. The limiting slide rod 2333 is fixedly mounted on the abutment plate 2335 and slides in conjunction with a sliding hole on the mounting bracket 21, thereby enabling the abutment plate 2335 to move stably in the width direction of the crossbeam while preventing unnecessary rotation or offset of the abutment plate 2335. The abutment roller 2336 is rotatably mounted on the abutment plate 2335 and can form rolling contact with the side of the crossbeam.

[0030] In actual use, the operator can start the drive motor 2321 according to the width of the crossbeam to be processed, so that the two sliding tables 2331 move closer or further apart synchronously. This drives the corresponding fixed frame 2332, auxiliary rod 2334 and abutment plate 2335 to adjust synchronously, so that a limiting space matching the width of the crossbeam is formed between the two abutment rollers 2336. After the crossbeam enters this limiting space, the abutment rollers 2336 constrain the crossbeam from both sides laterally, so that the crossbeam is not prone to lateral displacement during the conveying process.

[0031] Meanwhile, since the abutment roller 2336 can rotate relative to the abutment plate 2335, it can rotate along with the beam as the beam moves in the conveying direction. This reduces sliding friction between the limiting structure and the side of the beam, maintaining lateral limiting without significantly hindering the continuous conveying of the beam. The synchronous adjustment of the two limiting components 233 via the bidirectional lead screw 2325 also keeps the center position of the beam near the conveying path, reducing operational errors caused by repeatedly adjusting the position of one limiting component.

[0032] In this embodiment, the limiting component 23 is not only used for lateral limiting during the beam conveying process, but also forms a linkage relationship with the movement of the cutting mechanism 3 to shorten the initial path of the cutting mechanism 3 before the cutting work begins. The slide table 2331 in the limiting component 23 is connected to the linkage plate 31, so that when the slide table 2331 moves under the drive of the bidirectional lead screw 2325, it can synchronously drive the linkage plate 31 to move in the corresponding direction. The base plate 1 is provided with a clearance groove to avoid the linkage plate 31, so as to ensure that the linkage plate 31 is not interfered with by the base plate 1 during the movement.

[0033] The linkage plate 31 is equipped with a mounting plate 32 and a cutting assembly 33. Therefore, while adjusting the limiting components 233 on both sides, the linkage plate 31 can drive the mounting plate 32 and the cutting assembly 33 to adjust their positions as a whole. In this way, when processing crossbeams of different widths, not only can the position of the abutment roller 2336 be adjusted, but the cutting mechanism 3 can also be adjusted synchronously relative to the crossbeam, thereby maintaining a reasonable processing position between the cutter 333 and the crossbeam and reducing the need for the cutting mechanism 3 to perform large-range position adjustments alone.

[0034] Furthermore, in some embodiments of this application, such as Figure 4 As shown, the cutting mechanism 3 starts working after the crossbeam is transported to the predetermined cutting position. The cutting mechanism 3 includes a mounting plate 32, a linkage plate 31, a cutting assembly 33, and a pressing assembly 34. The mounting plate 32 is fixedly mounted on the linkage plate 31, and the cutting assembly 33 is mounted on the linkage plate 31 and located above or to the side of the crossbeam cutting area.

[0035] The cutting assembly 33 includes a hydraulic cylinder 331, a support frame 332, and a cutter 333. The hydraulic cylinder 331 is mounted on the mounting plate 32, and its extended end is connected to the support frame 332. The cutter 333 is rotatably mounted on the support frame 332. When the crossbeam reaches the cutting position, the hydraulic cylinder 331 is activated and pushes the support frame 332 towards the crossbeam, causing the cutter 333 to gradually approach the crossbeam and cut it.

[0036] During the cutting process, the support frame 332 not only supports and moves the cutter 333, but also provides auxiliary support to the cutting end of the crossbeam. Since the crossbeam is a strip-shaped component of a certain length, localized stress concentration can easily occur near the cutting position when the cutter 333 acts on it. By placing the support frame 332 close to the cutting area, it can provide a certain degree of support to the cutting end of the crossbeam, keeping the crossbeam relatively stable near the cutting position, thereby reducing the possibility of localized bending, warping, or denting of the crossbeam due to the cutting action.

[0037] To further improve the stability of the beam during the cutting process, such as Figure 6As shown, in this embodiment, a pressing assembly 34 is provided on the support frame 332. The pressing assembly 34 includes a connecting frame 341, a connecting plate 342, and a pressing component 343. The connecting frame 341 is fixedly mounted on the support frame 332, the connecting plate 342 is mounted on the connecting frame 341, and the pressing component 343 is disposed on the connecting plate 342. Since the pressing assembly 34 and the support frame 332 are installed in a linked manner, the pressing assembly 34 can move towards the crossbeam synchronously as the hydraulic cylinder 331 drives the support frame 332 to move downward.

[0038] Before or during the contact between the cutter 333 and the crossbeam, the pressing component 343 first abuts against the surface of the crossbeam, exerting downward pressure on it. At this time, the crossbeam is supported by the conveying roller 22 and pressed by the pressing component 343, and is also laterally constrained by the two abutment rollers 2336, resulting in a relatively stable force state for the crossbeam within the cutting area. As the cutter 333 further cuts into the crossbeam, the pressing component 343 restricts the crossbeam from jumping up and down or tilting up locally, thereby reducing the possibility of the cutting position shifting due to crossbeam vibration or uneven force during the cutting process.

[0039] In this embodiment, as Figure 6 As shown, the pressing component 343 adopts a structure with elastic adjustment function to accommodate crossbeams of different thicknesses. The pressing component 343 includes a mounting sleeve 3431, a slide cylinder 3432, a sliding plate 3433, a spring 3434, a sleeve rod 3435, a threaded rod 3436, a driven gear 3437, a transmission rod 3438, and a driving gear 3439.

[0040] The mounting sleeve 3431 is mounted on the connecting plate 342. The sliding cylinder 3432 is slidably engaged with the mounting sleeve 3431 via the sliding plate 3433. The mounting sleeve 3431 has a groove for the sliding plate 3433 to move, thus guiding the movement of the sliding cylinder 3432. Ball bearings are provided at the lower end of the sliding cylinder 3432 to ensure rolling contact when it contacts the crossbeam.

[0041] Spring 3434 is mounted on slide cylinder 3432 and located between slide cylinder 3432 and threaded rod 3436. Sleeve rod 3435 is threadedly connected to mounting sleeve 3431 via threaded rod 3436, with the top end of spring 3434 abutting against the bottom end of threaded rod 3436. By adjusting the thread within mounting sleeve 3431, the length of threaded rod 3436 extending into mounting sleeve 3431 can be changed, thereby altering the preload of spring 3434. This allows pressing component 343 to adjust the appropriate pressing force for beams of different thicknesses and structural strengths.

[0042] To facilitate adjustment of the axial position of the threaded rod 3436, this embodiment includes a meshing drive gear 3439 and a driven gear 3437 on the connecting frame 341. The driven gear 3437 is rotatably mounted on the connecting frame 341, and the threaded rod 3436 is slidably connected to it, allowing the driven gear 3437 to drive the threaded rod 3436 to rotate synchronously during rotation, while also allowing the threaded rod 3436 to move axially relative to the driven gear 3437. The drive gear 3439 is rotatably mounted on the connecting frame 341, and a transmission rod 3438 is connected to the drive gear 3439, with the drive gear 3439 meshing with the driven gear 3437.

[0043] In use, the operator rotates the transmission rod 3438, which drives the driving gear 3439 to rotate. The driving gear 3439, through gear meshing, drives the driven gear 3437 to rotate, and the driven gear 3437 further drives the threaded rod 3436, which is slidably connected to it, to rotate synchronously. Since the threaded rod 3436 is threadedly connected to the mounting sleeve 3431, the threaded rod 3436 can move axially along the mounting sleeve 3431 during rotation, thereby changing the relative position between the bottom end of the threaded rod 3436 and the slide cylinder 3432.

[0044] As the position of the threaded rod 3436 changes, the contact position between its bottom end and the spring 3434 changes accordingly, adjusting the preload of the spring 3434 and thus altering the elastic pressing force on the slide cylinder 3432. Simultaneously, the axial adjustment of the threaded rod 3436 also changes the initial position of the slide cylinder 3432, allowing the pressing height of the pressing component 343 to be adaptively adjusted according to crossbeams of different thicknesses. Therefore, while ensuring stable contact between the pressing component 343 and the crossbeam, excessive compression of the crossbeam due to mismatched pressing height or force is avoided.

[0045] Because the driven gear 3437 and the threaded rod 3436 are slidably connected, during the axial adjustment of the threaded rod 3436 along the mounting sleeve 3431, the driven gear 3437 can still maintain its meshing with the driving gear 3439 and continuously transmit rotational power to the threaded rod 3436, thus enabling the rotational adjustment and axial movement of the threaded rod 3436 to coordinate with each other. Compared to a structure in which the driven gear 3437 is directly fixed to the threaded rod 3436, this method allows the gear transmission structure to be adapted to the axial adjustment of the threaded rod 3436, improving the continuity and stability of the adjustment process of the pressing component 343.

[0046] It should be noted that, in order to facilitate the synchronous driving of the two sets of threaded rods 3436, the thread directions of the two sets of threaded rods 3436 are opposite.

[0047] When the hydraulic cylinder 331 pushes the support frame 332 and the pressing assembly 34 closer to the crossbeam, the balls at the lower end of the slide cylinder 3432 first or subsequently contact the surface of the crossbeam. As the support frame 332 continues to move, the slide cylinder 3432 is subjected to the reaction force of the crossbeam and slides relative to the mounting sleeve 3431, while simultaneously causing the spring 3434 to undergo elastic compression. Thus, the pressing component 343 can have a certain floating margin while maintaining a certain pressing force.

[0048] This structure is particularly suitable for processing scenarios where the surface of the crossbeam has slight dimensional deviations or different thicknesses. If the thickness of the crossbeam varies slightly in a local area, the slide cylinder 3432 can automatically compensate for the height change under the action of the spring 3434, ensuring that the balls remain in contact with the surface of the crossbeam without excessive concentrated pressure on the crossbeam due to rigid pressing. At the same time, the balls can roll along with the crossbeam during the conveying process, thereby reducing the frictional resistance between the crossbeam and the pressing component 343 under pressing conditions, allowing for both pressing and conveying to be carried out simultaneously.

[0049] After the crossbeam is cut, the cutter 333 resets under the action of the hydraulic cylinder 331, and the pressing assembly 34 releases its pressure on the crossbeam simultaneously with the support frame 332. The cut crossbeam is received by the unloading assembly 4 and unloaded, thus preventing the cut crossbeam from remaining in the cutting area. The unloading assembly 4 can adopt structural forms such as inclined guide, rolling conveyor, and receiving and transferring, depending on the actual equipment layout, to guide the cut crossbeam to the designated collection area.

[0050] To reduce the resistance during the movement of the linkage plate 31 and the slide table 2331, such as Figure 3 As shown, this embodiment also includes an auxiliary component 5. The auxiliary component 5 is located at the bottom of the linkage plate 31 and the slide table 2331, and includes an auxiliary plate 51 and an auxiliary wheel 52. The auxiliary plate 51 is connected to both the linkage plate 31 and the slide table 2331, and the auxiliary wheel 52 is rotatably mounted on the auxiliary plate 51 and abuts against the base plate 1.

[0051] When the limiting component 23 is adjusting its position, the slide table 2331 moves along the bidirectional lead screw 2325, while the auxiliary wheel 52 rolls on the base plate 1, changing the support of the slide table 2331 from direct sliding contact to rolling contact. Similarly, when the linkage plate 31 moves synchronously with the limiting component 23, its bottom auxiliary wheel 52 also rolls along the base plate 1, thus providing auxiliary support for the linkage plate 31. This reduces the frictional resistance of the linkage plate 31 and the slide table 2331 during movement, reduces the load on the drive component 232, and makes the position adjustment of the cutting mechanism 3 smoother.

[0052] The specific working process of this embodiment is as follows: First, according to the specifications of the crossbeam to be processed, the drive motor 2321 drives the drive sprocket 2322 to rotate, which in turn drives the driven sprocket 2323 and the double-acting screw 2325 to rotate via the chain 2324, causing the two side slides 2331 to move synchronously. The slides 2331 drive the fixed frame 2332, the auxiliary rod 2334 and the abutment plate 2335 to move, so that the two side abutment rollers 2336 are adjusted to a position that matches the width of the crossbeam; at the same time, the slides 2331 drive the linkage plate 31 and its mounting plate 32, cutting assembly 33 and pressing assembly 34 to adjust synchronously.

[0053] Subsequently, the crossbeam to be cut is placed on the conveying roller 22, and the crossbeam is brought into the limiting space formed by the two abutment rollers 2336. After the conveying roller 22 rotates, it drives the crossbeam to be conveyed to the cutting area. The abutment rollers 2336 limit the crossbeam laterally and roll synchronously as the crossbeam moves, so that the crossbeam can be kept in stable conveying.

[0054] Once the crossbeam reaches the predetermined cutting position, the conveying stops, and the hydraulic cylinder 331 activates, pushing the support frame 332 closer to the crossbeam. The pressing assembly 34 moves synchronously with the support frame 332, causing the balls at the lower end of the slide cylinder 3432 to abut against the crossbeam, forming a stable pressing force under the elastic action of the spring 3434. Simultaneously, the support frame 332 provides auxiliary support to the cutting end, and the cutter 333 continues to move downwards, cutting the crossbeam.

[0055] During the cutting process described above, the crossbeam is laterally restricted by the two abutment rollers 2336, and is also vertically pressed by the pressing component 343 and supported by the cutting end of the support frame 332. This forms a multi-directional constraint, making it difficult for the crossbeam near the cutting area to move laterally, jump up and down, or warp locally, thereby reducing the probability of problems such as dents and deformation caused by force concentration during the cutting process.

[0056] After cutting, the hydraulic cylinder 331 drives the support frame 332, the cutter 333, and the pressing assembly 34 to reset, releasing the pressure on the crossbeam. Subsequently, the cut crossbeam enters the unloading assembly 4, which guides and collects the crossbeam, thus completing a full crossbeam cutting and unloading cycle.

[0057] In this embodiment, the drive component 232 uses a drive motor 2321, a drive sprocket 2322, a driven sprocket 2323, and a chain 2324 to drive the bidirectional lead screw 2325. However, in other embodiments, the drive sprocket 2322, the driven sprocket 2323, and the chain 2324 can also be replaced with gear transmission, synchronous belt transmission, or other mechanical transmission structures that can transmit the rotational power of the drive motor 2321 to the bidirectional lead screw 2325, as long as the synchronous opposite or opposite movement of the two side limit components 233 can be achieved.

[0058] In other embodiments, the outer peripheral surface of the abutting roller 2336 may also be provided with a protective layer with a certain elasticity to further reduce the local compression of the side of the beam during the abutting process, while improving the adaptability of the beam to different surface conditions.

[0059] In other embodiments, the cutter 333 can be made of different types of cutting tools depending on the material and cross-sectional structure of the beam, as long as it can cooperate with the support frame 332 to complete the beam cutting. The hydraulic cylinder 331 can also be replaced with other linear drive structures depending on the equipment space and cutting load.

[0060] In other embodiments, the ball bearings at the bottom of the slide 3432 can be replaced by rollers or other support structures that can form rolling contact; the spring 3434 can be selected with different stiffness specifications according to the thickness of the crossbeam, the material strength and the required pressing force, so that the pressing assembly 34 has a wider range of adaptability.

[0061] In addition, the specific structure of the feeding component 4 can be adjusted according to the size and weight of the cut crossbeam and the layout of the production line. For example, a roller feeding device, an inclined guiding feeding device, or a mechanical transfer feeding device can be used to meet the needs of crossbeam collection and transfer in different production scenarios.

[0062] In summary, this embodiment utilizes the conveying roller 22 for rolling support during the beam conveying stage, and achieves synchronous adjustment of the beam width direction through the two-sided limiting components 233 driven by the bidirectional lead screw 2325, ensuring that beams of different specifications can maintain a stable position during conveying. Simultaneously, the limiting components 23 and the linkage plate 31 are linked, allowing the beam specification adjustment and the position adjustment of the cutting mechanism 3 to coordinate, reducing equipment adjustment steps. During the cutting stage, the crossbeam is constrained from multiple directions, including lateral limiting, vertical pressing, and cutting end support, through the coordinated cooperation of the cutter 333, support frame 332, and pressing component 34, reducing the possibility of beam swaying, warping, denting, or deformation during cutting. The spring 3434 in the pressing component 343 provides elastic compensation, and in conjunction with the threaded rod 3436 and gear adjustment structure, the pressing state can be adjusted according to different beam specifications. Meanwhile, the ball bearings at the bottom of the slide cylinder 3432 maintain rolling contact during pressing, thus balancing beam fixation and smooth conveying. The auxiliary component 5 provides rolling support for the linkage plate 31 and the slide table 2331 through the auxiliary wheel 52, which reduces the movement resistance of the mechanism and improves the stability and smoothness of the overall adjustment process.

[0063] Therefore, this application can improve the positioning stability and stress stability of the crossbeam in the cutting area while meeting the needs of conveying and cutting crossbeams of different specifications, reduce the occurrence of local deformation or dents at the cutting position, and help improve the flatness of the crossbeam cutting surface and the subsequent processing quality. At the same time, through the linkage adjustment of the limiting component 23 and the cutting mechanism 3, the repeated adjustment operation during the processing of crossbeams of different specifications is reduced, and the ease of use and applicability of the equipment are improved.
