Description

A hydraulic steel plate shearing machine Technical Field

[0001] This utility model relates to the field of steel plate processing technology, specifically to a hydraulic steel plate shearing machine. Background Technology

[0002] Hydraulic shearing machines are important equipment in the steel structure production field, playing a crucial role in the steel plate cutting process.

[0003] A search revealed that utility model patent application CN107855587A discloses a steel plate clamping fixture for a hydraulic shearing machine. While this device effectively clamps the steel plates to be processed, saving time and labor, reducing worker workload, increasing production efficiency, and lowering labor costs, it relies on mechanical structures such as springs for compression and limiting. This method has significant drawbacks. In actual operation, uneven force often leads to displacement after limiting, greatly affecting the stability of the clamped steel plate. Furthermore, the direct shearing process using blades is prone to deformation at the shearing position, making it difficult to guarantee product quality. These technical bottlenecks severely restrict the improvement of production efficiency and processing accuracy, urgently requiring optimization and improvement through technological innovation. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a hydraulic steel plate shearing machine, which solves the problems mentioned in the background art.

[0005] The solution to the above-mentioned technical problems provided by this utility model is as follows:

[0006] A hydraulic steel plate shearing machine includes a processing panel, on which a second hydraulic rod and a third hydraulic rod are provided. A shearing blade is installed at the output shaft end of the third hydraulic rod, and the shearing blade is used to shear steel plates.

[0007] The output end of the second hydraulic rod is equipped with a grooving blade, which is used to cut grooves in the steel plate;

[0008] The processing panel has a connecting groove, and a tray is provided on the processing panel. A first hydraulic rod is installed on the tray via a mounting block. A through hole is provided in the tray. An L-shaped limiting frame is installed on the output end of the first hydraulic rod. A screw is installed in the L-shaped limiting frame via a thread. An extrusion block is fixedly installed on the bottom end face of the screw. The extrusion block and the L-shaped limiting frame are used to extrude, clamp, and limit the steel plate in the tray.

[0009] The bottom surface of the processing panel is equipped with a fourth hydraulic rod via a U-shaped crossbeam, and an extrusion plate is installed on the output end of the fourth hydraulic rod.

[0010] Based on the above technical solution, the present invention can be further improved as follows.

[0011] Furthermore, top plates are mounted on the second and third hydraulic rods via I-beams, and mounting brackets are bolted to the bottom surfaces of the top plates. The bottom surfaces of the mounting brackets are fixed to the processing panel.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: the second and third hydraulic rods are connected to the top plate by the I-beam frame, and the top plate is fixed to the processing panel by the mounting frame, forming a stable support structure. When the pallet moves the steel plate to the bottom end of the second hydraulic rod, the second hydraulic rod can drive the grooving blade to move down. When the grooving blade moves down, it opens a shearing groove in the steel plate. After the groove is opened, the personnel push the pallet to the bottom end of the third hydraulic rod, so that the third hydraulic rod opens and drives the grooving blade into the groove opened in the steel plate to shear the steel plate. By grooving and then shearing, the deformation of the steel plate caused by direct squeezing and shearing is avoided.

[0013] Furthermore, a support frame is installed on the bottom surface of the processing panel, and a support block is welded to the bottom surface of the support frame.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the combination of the support frame and the support block provides a stable support foundation for the entire hydraulic steel plate shearing machine.

[0015] Furthermore, a slide rail is installed on the processing panel, which limits the position of the tray and allows the tray to slide within the slide rail.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the slide rail provides precise motion guidance for the pallet, making the pallet slide more smoothly and steadily on the processing panel. The limiting function of the slide rail ensures that the pallet will not deviate during sliding, guaranteeing the accuracy of steel plate positioning. This not only improves processing efficiency but also avoids processing errors caused by pallet deviation, thereby enhancing the processing accuracy and production quality of the equipment.

[0017] Furthermore, a connecting block is welded onto the screw, a gripping frame is mounted on the connecting block, and a spring washer is provided on the bottom end face of the connecting block, the spring washer being sleeved on the screw.

[0018] The beneficial effects of adopting the above-mentioned further solution are as follows: After the steel plate is placed in the pallet, the operator manually rotates the screw using the gripper. As the screw spirals downward, it drives the extrusion block to limit the top surface of the steel plate. Furthermore, the operator can open the first hydraulic rod to activate the L-shaped limiting frame to clamp and limit the four corners of the steel plate, ensuring that the steel plate is firmly clamped during processing and preventing loosening or displacement, thereby improving the stability and safety of the processing. The function of the spring washer is to provide extrusion force to compress the connecting block when the screw is tightened, preventing the screw from reversing.

[0019] Furthermore, a connecting plate is installed on the side end face of the tray, and a handle is fixedly installed on the connecting plate.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the installation of the handle provides the operator with a convenient point of force application. When it is necessary to move the pallet, the operator can easily push the pallet to slide on the slide rail by holding the handle.

[0021] Furthermore, the extrusion plate is slidably sleeved in the connecting groove and through hole, and the extrusion plate is used to extrude and limit the steel plate in the tray.

[0022] The beneficial effects of adopting the above-mentioned further solution are as follows: When shearing or grooving steel plates, simply limiting the four corners and top surface of the steel plate is insufficient to completely fix it, especially since lateral forces and vibrations generated during processing can easily cause the bottom surface of the steel plate to shift. However, the extrusion plate, by slidingly fitting within the connecting groove and through hole, can move upwards under the drive of the fourth hydraulic rod, applying pressure to the bottom surface of the steel plate. In conjunction with the L-shaped limiting frame and the extrusion block, it achieves omnidirectional clamping and limiting of the steel plate. This multi-directional limiting method greatly enhances the stability of the steel plate during processing, effectively preventing deformation or displacement due to uneven force, improving processing accuracy and product quality, and also reducing equipment failures and safety hazards caused by steel plate displacement.

[0023] Furthermore, a guide rod is welded to the bottom end face of the extrusion plate, and the guide rod is slidably sleeved inside the U-shaped crossbeam.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the guide rod provides precise guidance for the movement of the extrusion plate, ensuring that the extrusion plate can move stably up and down in the vertical direction under the drive of the fourth hydraulic rod, avoiding tilting or deviation.

[0025] This utility model provides a hydraulic steel plate shearing machine. It has the following beneficial effects:

[0026] The second and third hydraulic rods are connected to the top plate via an I-beam frame, and the top plate is then fixed to the processing panel using a mounting bracket, forming a stable support. This structure allows the second hydraulic rod to drive the grooving blade to cut shearing grooves in the steel plate, and then the third hydraulic rod drives the shearing blade to cut the plate through the grooves, avoiding direct compression that could deform the steel plate and ensuring the quality of the shearing.

[0027] The connecting block, gripping frame, and spring washers on the screw, together with the L-shaped limiting frame driven by the first hydraulic rod, can firmly clamp and limit the steel plate. The operator rotates the screw via the gripping frame to limit the extrusion block against the top surface of the steel plate. The first hydraulic rod drives the L-shaped limiting frame to clamp the four corners of the steel plate, and the spring washers prevent the screw from reversing, ensuring that the steel plate will not loosen or shift during processing, thus improving the stability and safety of the processing.

[0028] The extrusion plate slides within the connecting groove and through hole, applying pressure to the bottom surface of the steel plate under the drive of the fourth hydraulic rod. This, combined with the L-shaped limiting frame and extrusion block, achieves omnidirectional clamping and limiting of the steel plate. This method effectively prevents deformation or displacement of the steel plate due to uneven force, improving processing accuracy and product quality, and reducing equipment failures and safety hazards.

[0039] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0040] Please refer to Figures 1 to 6 for the embodiments provided by this utility model:

[0041] Example 1

[0042] A hydraulic steel plate shearing machine includes a processing panel 1, on which a second hydraulic rod 304 and a third hydraulic rod 302 are provided. A shearing blade 306 is installed at the output shaft end of the third hydraulic rod 302. The shearing blade 306 is used to shear steel plates.

[0043] The output end of the second hydraulic rod 304 is equipped with a grooving blade 305, which is used to cut grooves in the steel plate.

[0044] The processing panel 1 has a connecting groove 104 and a tray 2. A first hydraulic rod 206 is installed on the tray 2 via a mounting block 203. A through hole 204 is provided in the tray 2. An L-shaped limit frame 205 is installed on the output end of the first hydraulic rod 206. A screw 209 is installed in the L-shaped limit frame 205 via a thread. An extrusion block 210 is fixedly installed on the bottom end face of the screw 209. The extrusion block 210 and the L-shaped limit frame 205 are used to extrude, clamp and limit the steel plate in the tray 2.

[0045] The bottom end of the processing panel 1 is equipped with a fourth hydraulic rod 401 via a U-shaped crossbeam 4, and an extrusion plate 403 is installed on the output end of the fourth hydraulic rod 401.

[0046] A slide rail 103 is installed on the processing panel 1. The slide rail 103 limits the movement of the pallet 2, and the pallet 2 is slidably fitted within the slide rail 103. The slide rail 103 provides precise motion guidance for the pallet 2, making the sliding of the pallet 2 on the processing panel 1 more stable and smooth. The limiting function of the slide rail 103 ensures that the pallet 2 will not deviate during the sliding process, guaranteeing the accuracy of the steel plate positioning. This not only improves processing efficiency but also avoids processing errors caused by the deviation of the pallet 2, thereby improving the processing accuracy and production quality of the equipment.

[0047] A connecting block 207 is welded onto the screw 209, and a gripping frame is installed on the connecting block 207. A spring washer 208 is provided on the bottom surface of the connecting block 207. The spring washer 208 is sleeved on the screw 209. The operator then places the steel plate in the tray 2. After placement, the operator manually rotates the screw 209 through the gripping frame. When the screw 209 spirals downward, it drives the extrusion block 210 to limit the top surface of the steel plate. The operator can also open the first hydraulic rod 206 to drive the L-shaped limiting frame 205 to clamp and limit the four corners of the steel plate, ensuring that the steel plate is firmly clamped during processing and preventing loosening and displacement, thereby improving the stability and safety of the processing. The function of the spring washer 208 is to provide extrusion force to the connecting block 207 when the screw 209 is tightened, preventing the screw 209 from reversing.

[0048] A connecting plate 201 is installed on the side end face of the tray 2, and a handle 202 is fixedly installed on the connecting plate 201. The installation of the handle 202 provides the operator with a convenient point of force application. When it is necessary to move the tray 2, the operator can easily push the tray 2 to slide on the slide rail 103 by holding the handle 202.

[0049] Example 2

[0050] To limit the bottom surface of the steel plate during processing and prevent displacement of the bottom surface after limiting the four corners and top surface of the steel plate, as exemplarily shown in Figures 1 to 6, this utility model also includes:

[0051] The extrusion plate 403 is slidably sleeved within the connecting groove 104 and the through hole 204. The extrusion plate 403 is used to extrude and limit the steel plate within the tray 2. When shearing or grooving the steel plate, limiting only the four corners and top surface of the steel plate is insufficient to completely fix it, especially as lateral forces and vibrations generated during processing can easily cause the bottom surface of the steel plate to shift. However, the extrusion plate 403, slidably sleeved within the connecting groove 104 and the through hole 204, can move upwards under the drive of the fourth hydraulic rod 401, applying pressure to the bottom surface of the steel plate. In conjunction with the L-shaped limiting frame 205 and the extrusion block 210, it achieves omnidirectional clamping and limiting of the steel plate. This multi-directional limiting method greatly enhances the stability of the steel plate during processing, effectively preventing deformation or displacement due to uneven force, improving processing accuracy and product quality, and also reducing equipment failures and safety hazards caused by steel plate displacement.

[0052] A guide rod 402 is welded to the bottom end face of the extrusion plate 403. The guide rod 402 is slidably sleeved in the U-shaped crossbeam 4. The guide rod 402 provides precise guidance for the movement of the extrusion plate 403, ensuring that the extrusion plate 403 can move stably up and down in the vertical direction under the drive of the fourth hydraulic rod 401, avoiding tilting or deviation.

[0053] Example 3

[0054] To pre-groove the steel plate during processing and avoid deformation caused by direct shearing, as exemplarily shown in Figures 1 to 6, this utility model also includes:

[0055] A top plate 301 is mounted on the second hydraulic rod 304 and the third hydraulic rod 302 via an I-beam 303. A mounting bracket 3 is bolted to the bottom surface of the top plate 301. The bottom surface of the mounting bracket 3 is fixed to the processing panel 1. The second hydraulic rod 304 and the third hydraulic rod 302 are connected to the top plate 301 via the I-beam 303, and the top plate 301 is fixed to the processing panel 1 by the mounting bracket 3, forming a stable support structure. When the pallet 2 moves the steel plate to the bottom surface of the second hydraulic rod 304, the second hydraulic rod 304 can drive the grooving blade 305 to move downward. When the grooving blade 305 moves downward, it opens a shearing groove in the steel plate. After the groove is opened, the personnel push the pallet 2 to the bottom surface of the third hydraulic rod 302, so that the third hydraulic rod 302 opens and drives the grooving blade 305 into the groove opened in the steel plate to shear the steel plate. By grooving before shearing, the steel plate is not deformed by direct squeezing and shearing.

[0056] A support frame 101 is installed on the bottom surface of the processing panel 1, and a support block 102 is welded to the bottom surface of the support frame 101. The combination of the support frame 101 and the support block 102 provides a stable support foundation for the entire hydraulic steel plate shearing machine.

[0057] Working principle:

[0058] Steel plate loading and fixing: The steel plate is placed in the tray 2. The operator manually rotates the screw 209 by holding the frame. The screw 209 moves downward and drives the extrusion block 210 to limit the top surface of the steel plate.

[0059] Open the first hydraulic rod 206, which drives the L-shaped limiting frame 205 to clamp and limit the four corners of the steel plate, thus achieving initial fixation of the steel plate.

[0060] Steel plate position adjustment: A connecting plate 201 and a handle 202 are installed on the side end face of the pallet 2. The operator holds the handle 202 and pushes the pallet 2 to slide on the slide rail 103, so that the pallet 2 moves the steel plate to the bottom end face of the second hydraulic rod 304.

[0061] Steel plate grooving: The second hydraulic rod 304 and the third hydraulic rod 302 are connected to the top plate 301 through the I-beam 303. The top plate 301 is fixed on the processing panel 1 through the mounting bracket 3 to form a stable support structure.

[0062] The second hydraulic rod 304 opens, causing the grooving blade 305 installed at its output end to move downward, thus creating a shearing groove in the steel plate.

[0063] Steel plate shearing: After the slot is cut, the operator pushes the pallet 2, which causes the steel plate to continue sliding until it reaches the bottom end of the third hydraulic rod 302.

[0064] The third hydraulic rod 302 opens, driving the shearing blade 306 into the slot opened in the steel plate to perform a shearing operation on the steel plate.

[0065] All-around positioning of the steel plate: When shearing or grooving the steel plate, simply positioning the four corners and top surface is insufficient to completely fix the steel plate. At this time, the fourth hydraulic rod 401 is activated, and its output end drives the extrusion plate 403 to move.

[0066] The extrusion plate 403 is slidably sleeved in the connecting groove 104 and the through hole 204. Driven by the fourth hydraulic rod 401, it moves upward and applies pressure to the bottom end face of the steel plate. In cooperation with the L-shaped limiting frame 205 and the extrusion block 210, it realizes all-round clamping and limiting of the steel plate, and enhances the stability of the steel plate during the processing.

[0067] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
