[0043] Compared with the prior art, the present invention has the following beneficial effects:

[0044] 1. The present invention is equipped with a material rotation module, which executes the coordinated work of motor 1, vertical reducer, material plate and limit plate to achieve precise rotational positioning of the material to be sheared. This is crucial for materials that require shearing at a specific angle and can greatly improve the precision and efficiency of shearing. The limit plate and the slide rail on it cooperate with the limit groove and pulley inside the display table to provide stable support and positioning for the material, which not only ensures the stability of the material during the rotation process, but also prevents the material from accidentally moving before shearing, further improving the accuracy of shearing. The pressure sensor embedded in the pulley surface can monitor the pressure of the material when it is placed on the material plate for rotation or movement in real time, which helps to promptly detect and deal with possible overload or imbalance conditions, thereby ensuring the safe operation of the hydraulic shearing machine. The laser ranging sensor set on the edge of the material plate can measure the distance between the edge of the material plate and the display table in real time, which is crucial for accurately controlling the shearing position and angle of the material. Through real-time measurement and adjustment, it can be ensured that each shearing can achieve the expected accuracy, thereby solving the problems of inaccurate material rotation positioning, poor material stability, lack of overload and imbalance monitoring, and inaccurate shearing position and angle control of traditional hydraulic shearing machines.

[0045] 2. The present invention is equipped with a feed moving module, and the coordinated action of the ball screw driven by the execution motor 2 and the sliding auxiliary rod realizes the precise movement of the placing table on the top of the shearing machine body, ensures the accurate positioning of the material before shearing, and improves the shearing accuracy. The displacement sensor 1 embedded in the slider can measure the position of the placing table in the feeding direction in real time, and provides accurate feedback for the control system, thereby realizing precise control of the material position. The position sensor 2, speed sensor and operation status monitoring sensor arranged on the outside of the execution motor 1 and the execution motor 2 can monitor the rotation position, rotation speed, temperature and vibration parameters of the motor in real time. These parameters are crucial for judging the operating status of the motor, preventing faults and timely maintenance. Through these sensors, the control system of the hydraulic shearing machine can timely detect abnormal conditions of the motor, including overheating, overload and excessive vibration, so as to take measures in advance to avoid failures. The occurrence of malfunctions ensures the stable operation of the hydraulic shearing machine. The torque sensor and speed sensor at the output end of the vertical reducer can respectively measure the torque and speed of the reducer. These data are of great significance for evaluating the performance of the reducer, optimizing the shearing process and preventing reducer failures. By monitoring the changes in torque and speed, the system can promptly detect abnormal conditions inside the reducer, thereby taking corresponding maintenance measures to extend the service life of the hydraulic shearing machine. The present invention realizes the automatic control of materials from feeding, positioning to shearing through multi-axis collaborative work, which not only improves production efficiency, but also reduces the labor intensity of operators. At the same time, by integrating various sensors and control systems, the present invention realizes precise control and optimization of the shearing process, improves the quality and consistency of the product, and thus can solve the problems of inaccurate horizontal positioning of materials in traditional shearing machines, lack of real-time feedback and precise control, low production efficiency and high labor intensity.

[0046] 3. The present invention is equipped with a running lubrication module to provide continuous lubrication for the rotation of the material, effectively reducing the friction between the material and the roller and pulley, and extending the service life of the hydraulic shearing machine. The design of the oil storage tank allows the lubricating oil to be stored, and when needed, it is absorbed and released by sponge 1 and sponge 2 to provide a stable lubrication supply for the rotation of the material, which not only ensures the full utilization of the lubricating oil, but also avoids the failure of the hydraulic shearing machine caused by excessive or insufficient lubricating oil. The setting of sponge 1 and sponge 2 allows the lubricating oil to be continuously and evenly distributed between the material and the roller and pulley, thereby ensuring the durability of the lubrication effect and helping to reduce the damage caused by uneven lubrication. The hydraulic shearing machine is unevenly distributed and causes wear and reduced shearing accuracy. By synchronously setting a lubrication module inside the pulley and roller, the coordinated lubrication between the pulley and the roller is achieved, which not only improves the overall lubrication effect of the hydraulic shearing machine, but also ensures the stability and shearing accuracy of the material during rotation. The design of the running lubrication module makes the maintenance of the hydraulic shearing machine simpler and more convenient. The operator can regularly check and replenish the lubricating oil, thereby reducing the maintenance cost and time cost of the hydraulic shearing machine. Therefore, it can solve the problem that the rotation of the material in the traditional hydraulic shearing machine lacks sufficient lubrication, resulting in increased wear and friction, which in turn affects the operation efficiency and shearing accuracy of the hydraulic shearing machine.

[0047] 4. The present invention is equipped with an oil supply assembly, and the oil supply pipe transports the lubricating oil from the oil storage tank to the oil storage tank, ensuring continuous lubrication of the material during rotation. Traditional hydraulic shearing machines have shortcomings in the storage and management of lubricating oil, including the fact that the lubricating oil is easily leaked, contaminated or exhausted, resulting in poor lubrication effect of the hydraulic shearing machine. The oil storage tank design of the present invention solves this problem. The oil storage tank is located inside the display table and is connected to the oil supply pipe through an oil suction pipe and a water pump to form a complete lubricating oil supply system, which not only facilitates the storage and management of lubricating oil, but also reduces the risk of leakage and contamination of lubricating oil. At the same time, the oil supply assembly of the present invention The component design reduces the maintenance cost of the hydraulic shearing machine. Through the automatic and stable lubricating oil supply system, the number of manual interventions and frequent replacement of lubricating oil is reduced, thereby reducing the maintenance cost and time cost of the hydraulic shearing machine. The oil supply component of the present invention also improves the rotational stability and shearing accuracy of the material by ensuring continuous and stable lubricating oil supply. At the same time, since the failure and downtime of the hydraulic shearing machine caused by insufficient lubrication are reduced, the overall operating efficiency of the hydraulic shearing machine is also improved. Therefore, it can solve the problem of insufficient and unstable lubricating oil supply in traditional hydraulic shearing machines, which in turn affects the lubrication effect of the hydraulic shearing machine.

[0059] See also Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 and Figure 7 The present invention provides an embodiment of a multi-axis coordinated precise positioning hydraulic shearing machine, comprising a shearing machine body 1, a feed moving module is provided on the top of the shearing machine body 1, a placement table 2 is provided on the top of the feed moving module, a material rotation module is provided on the top of the placement table 2, the feed moving module is used to horizontally move the placement table 2, and the material rotation module is used to rotate the material to be sheared;

[0060] The material rotation module includes an executive motor 1 arranged on the top of the display table 2, and a vertical reducer 4 is provided at the output end of the executive motor 1. A material plate 5 is provided on the top of the vertical reducer 4 through a rotating shaft, and a limit plate 6 is provided on the outer side of the material plate 5. The top, bottom and side of the limit plate 6 are provided with symmetrically arranged slide rails 7;

[0061] The interior of the placing table 2 is provided with a limiting groove 8, and the top wall, bottom wall and side wall of the limiting groove 8 are provided with symmetrically arranged support frames. The surfaces of the two groups of support frames close to each other are penetrated by rollers 9, and the outer surface of the rollers 9 is sleeved with pulleys 10. The slide rail 7 on the top of the limiting plate 6 is located below the pulley 10 on the top wall of the limiting groove 8, the slide rail 7 at the bottom of the limiting plate 6 is located above the pulley 10 on the bottom wall of the limiting groove 8, and the slide rail 7 on the side of the limiting plate 6 is located on one side of the pulley 10 on the side wall of the limiting groove 8;

[0062] A pressure sensor is embedded in the surface of the pulley 10, which is used to monitor the pressure of the material when it is placed on the material plate 5 and rotated or moved;

[0063] A laser distance measuring sensor is provided at the edge of the material plate 5 , and the laser distance measuring sensor is used to measure the distance between the edge of the material plate 5 and the placement table 2 in real time.

[0064] Furthermore, a placement table 2 is provided on the top of the feed moving module. The placement table 2 provides a stable support platform for the subsequent placement and operation of materials, and a material rotation module is provided on the top of the placement table 2. The material rotation module is used to rotate the material to be sheared so that the angle of the material can be accurately adjusted to meet various different shearing requirements, including some decorative panels that need to be cut at a specific angle or workpieces with special shape requirements. The material rotation module can ensure that the material is in the best angle position before shearing.

[0065] The material rotation module includes an actuator motor 1 mounted atop a display table 2. This motor serves as a power source, boasting excellent power output and precise control capabilities. A vertical reducer 4 is tightly mounted on its output end. This reducer effectively adjusts the speed and torque output by actuator motor 1, ensuring that the power delivered to subsequent components meets operational requirements while remaining stable and reliable. A material plate 5 is mounted atop the vertical reducer 4 via a sturdy rotating shaft. This plate directly supports the material to be sheared. A limit plate 6 is positioned on the outside of the plate, with symmetrically arranged slide rails 7 positioned on its top, bottom, and sides.

[0066] The interior of the placing table 2 is provided with a limit slot 8, and the top, bottom and side walls of the limit slot 8 are provided with symmetrically arranged support frames. These support frames provide stable support for the roller shaft 9 installed later. The surfaces of the two sets of support frames close to each other are penetrated by the roller shaft 9, and the outer surface of the roller shaft 9 is tightly connected with the pulley 10. This structural design allows the outer limit plate 6 to form a sliding fit with the pulley 10 through the slide rail 7 when the material plate 5 rotates. Specifically, the slide rail 7 on the top of the limit plate 6 is located below the pulley 10 on the top wall of the limit slot 8, the slide rail 7 on the bottom of the limit plate 6 is located above the pulley 10 on the bottom wall of the limit slot 8, and the slide rail 7 on the side of the limit plate 6 is located on one side of the pulley 10 on the side wall of the limit slot 8. Through this arrangement, it can not only ensure that the material plate 5 has sufficient support and guidance during the rotation process, but also minimize friction resistance, making the rotation of the material plate 5 smoother and more accurate, but also reduce the energy loss of the hydraulic shearing machine during operation, and improve the overall operating efficiency of the hydraulic shearing machine.

[0067] A pressure sensor is embedded in the surface of the pulley 10. The pressure sensor is an important monitoring element to ensure the stability of the material placement and rotation process. The pressure sensor is used to monitor the pressure of the material when it is placed on the material plate 5 for rotation or movement. When the material is placed on the material plate 5, the pressure sensor can sense the size and distribution of the pressure applied by the material to the pulley 10 in real time. If the pressure distribution is uneven, it means that the material is not placed stably or there is a local overweight. At this time, the operator can promptly reposition or adjust the material according to the information fed back by the pressure sensor to ensure that the material will not slide or deflect due to uneven pressure during the rotation process, thereby ensuring the accuracy of the material rotation and the normal operation of the hydraulic shearing machine.

[0068] A laser distance sensor is provided at the edge of the material plate 5. The laser distance sensor is used to measure the distance between the edge of the material plate 5 and the display table 2 in real time. During the material rotation process, the laser distance sensor can continuously monitor the change in the distance between the edge of the material plate 5 and the display table 2. Once it is found that the distance exceeds the preset range, it means that the material plate 5 has excessively deviated during the rotation process or has collided with other components. Abnormal conditions such as the control system can adjust the operating state of the execution motor 1 in a timely manner according to the information fed back by the laser distance sensor, including adjusting the speed and changing the direction of rotation, so that the material plate 5 returns to the correct position and ensures the accuracy and safety of the material rotation. At the same time, before the shearing operation, the laser distance sensor can also provide accurate distance information to help the operator or the control system further confirm whether the position of the material is accurate, and provide reliable data support for subsequent shearing operations.

[0069] See also Figure 1 、 Figure 2 and Figure 6 The present invention provides an embodiment of a multi-axis coordinated precise positioning hydraulic shearing machine, wherein the feed moving module includes a fixed box 11 evenly arranged on the top of the shearing machine body 1, an actuator motor 2 is provided on the front of the fixed box 11, and a ball screw 12 is provided at the output end of the actuator motor 2, and one end of the ball screw 12 is connected to the inner wall of one side of the fixed box 11 through a shaft;

[0070] The interior of the fixed box 11 is provided with symmetrically arranged sliding auxiliary rods 13, and two groups of sliding auxiliary rods 13 are respectively located on both sides of the ball screw 12. The outer surfaces of the ball screw 12 and the sliding auxiliary rod 13 are sleeved with sliders 14, and the sliders 14 are arranged at the bottom of the display table 2.

[0071] Furthermore, the feed movement module includes fixed boxes 11 evenly arranged on top of the shearing machine body 1. These fixed boxes 11 are evenly distributed, providing a stable and balanced support structure for the entire feed movement system. Actuator Motor 2 is located on the front of the fixed boxes 11. As the core power source of the feed movement module, actuator Motor 2 has precise power output control capabilities, enabling precise adjustment of parameters such as output power and speed according to the different operating requirements of the shearing machine.

[0072] A ball screw 12 is mounted at the output end of actuator motor 2. This ball screw 12 performs the crucial task of converting the rotary motion of actuator motor 2 into linear motion throughout the entire feed movement process. One end of the ball screw 12 is connected to the inner wall of the stationary box 11 via a shaft. This connection ensures the stability of the ball screw 12 during rotation while allowing it to rotate smoothly within the space confined by the stationary box 11. The shaft ensures that the ball screw 12 will not become loose or eccentric during long-term operation, thereby maintaining stable transmission performance.

[0073] Inside the fixed box 11, symmetrically arranged auxiliary sliding rods 13 are installed, with two sets of auxiliary sliding rods 13 located on either side of the ball screw 12. These auxiliary sliding rods 13 primarily provide additional guidance and support for the linear motion of the slider 14, ensuring that the slider 14 remains stable and follows the predetermined linear trajectory during movement. Working in conjunction with the ball screw 12, they form a stable and precise linear motion guidance system.

[0074] Slider 14 is sleeved onto the outer surfaces of ball screw 12 and auxiliary sliding rod 13, and is mounted on the bottom of display table 2. As a key component connecting display table 2 to the feeder module's transmission, slider 14 transmits the linear motion of ball screw 12 to display table 2, enabling precise movement of display table 2 in the feed direction. Furthermore, by cooperating with auxiliary sliding rod 13, it further enhances the stability and precision of its own motion.

[0075] When the hydraulic shearing machine is running, when the execution motor 2 starts and outputs power, it drives the ball screw 12 to rotate. The rotational movement of the ball screw 12 causes the slider 14 connected to it to move linearly along the axial direction of the ball screw 12. At the same time, the slider 14 is guided and supported by two sets of sliding auxiliary rods 13 to maintain a smooth and accurate linear movement trajectory. Since the slider 14 is set at the bottom of the display table 2, the linear movement of the slider 14 directly drives the display table 2 to move accordingly in the feeding direction. Through this collaborative working mode, the feed movement module can accurately control the feeding position of the display table 2 according to the different working requirements of the hydraulic shearing machine, provide accurate material transportation and positioning for subsequent material shearing operations, and meet the production tasks of various plate sizes and shearing requirements.

[0076] See also Figure 1 、 Figure 2 and Figure 3 , an embodiment provided by the present invention: a multi-axis coordinated precise positioning hydraulic shearing machine, wherein a displacement sensor 1 is embedded in the interior of the slider 14, and the displacement sensor 1 is used to measure the position of the placing table 2 in the feeding direction in real time;

[0077] Position sensor 2, speed sensor and operation status monitoring sensor are provided on the outside of the execution motor 1 and the execution motor 2. Position sensor 2, speed sensor and operation status monitoring sensor are used to measure the rotation position, rotation speed, temperature and vibration parameters of the execution motor 1 and the execution motor 2 respectively;

[0078] The output end of the vertical reducer 4 is provided with a torque sensor and a speed sensor, which are used to measure the torque and speed of the vertical reducer 4 respectively.

[0079] Furthermore, the displacement sensor in the slider 14 is tightly integrated with the slider 14. Based on the principle of optical coding or electromagnetic induction, it captures the displacement data when the slider 14 moves linearly with the ball screw 12 and converts it into an electrical signal, providing the control system with the feed position information of the placement table 2. It is the key to precise shearing positioning, ensuring product dimensional accuracy and reducing waste.

[0080] Position sensor 2 can monitor the rotational position of actuator motor 1 for precise material angle control and feed positioning in combination with ball screw 12 monitoring. The speed sensor adjusts the speed of the actuator motor according to the characteristics of the plate to ensure stable and efficient material rotation. The temperature and vibration sensors in the operating status monitoring sensor monitor the motor temperature and vibration respectively, triggering alarms and prompting maintenance in the event of an abnormality, thus ensuring the stable operation of the actuator motor in multiple dimensions.

[0081] The torque sensor accurately measures the output torque of the vertical reducer 4, compares the actual torque with the preset torque according to the plate material, size and process requirements, and adjusts the power of the execution motor to ensure appropriate torque output. The speed sensor monitors the output speed of the vertical reducer 4 to grasp the actual rotation speed of the material plate 5 and assist in judging the status of its internal transmission components, ensuring efficient and accurate operation of the material rotation module and even the entire shearing machine.

[0082] See also Figure 4 and Figure 5 , an embodiment provided by the present invention: a multi-axis coordinated precise positioning hydraulic shearing machine, wherein the roller shaft 9 is provided with an operating lubrication module inside, and the operating lubrication module is used to provide continuous lubrication for the rotation of the material;

[0083] The running lubrication module includes an oil storage tank 15 opened inside the roller shaft 9, a fixed cylinder 16 is provided at the top and bottom of the oil storage tank 15, and a sponge 17 is provided inside the fixed cylinder 16;

[0084] The interior of the pulley 10 is embedded with symmetrically arranged sponges 2 18, and the upper group of sponges 2 18 is located above the upper group of sponges 17, and the lower group of sponges 2 18 is located below the lower group of sponges 17. A fixing rod 19 is provided through the interior of the sponge 2 18, and the fixing rod 19 is embedded in the interior of the pulley 10.

[0085] Furthermore, the oil storage tank 15 inside the roller 9 is the storage base for the lubricating oil in the entire lubrication system. The oil storage tank 15 is opened inside the roller 9. The fixed cylinders 16 set at the top and bottom of the oil storage tank 15, on the one hand, play a protective role to prevent the lubricating oil in the oil storage tank 15 from excessive shaking or leakage; on the other hand, the fixed cylinder 16 provides a stable installation space for the internal sponge 17. Sponge 17 has good oil absorption and oil storage properties. It can fully absorb and store the lubricating oil in the oil storage tank 15. Due to its porous structure, the lubricating oil can be evenly distributed in sponge 17. During the operation of the hydraulic shearing machine, when the relative movement between the roller 9 and the pulley 10 produces slight pressure changes and gap changes, the lubricating oil in sponge 17 can slowly seep out, thereby lubricating the contact parts between the roller 9 and the pulley 10.

[0086] The symmetrically arranged second sponges 18 embedded within pulley 10 work in conjunction with first sponges 17. The upper second sponge 18 is located above the upper first sponge 17, while the lower second sponge 18 is located below the lower first sponge 17. This arrangement facilitates the transfer of lubricating oil between the two. The second sponge 18 also has excellent oil absorption and storage capabilities. A fixing rod 19 running through it securely fixes the second sponge 18 to the pulley 10, preventing it from shifting or falling off during operation of the hydraulic shearing machine.

[0087] During the operation of the hydraulic shearing machine, as the roller 9 rotates, the lubricating oil in the oil storage tank 15 seeps out to the contact area between the roller 9 and the pulley 10 under the action of sponge 17. At this time, sponge 2 18 will use its positional relationship with sponge 17 and its own oil absorption characteristics to absorb the lubricating oil from sponge 17 and further distribute the lubricating oil to the contact surface between the pulley 10 and the slide rail 7. Through this multi-stage oil absorption and oil discharge mechanism that cooperates with sponge 17 and sponge 2 18, the lubricating oil can be supplied to various parts that need lubrication during the operation of the hydraulic shearing machine more accurately and efficiently. Even if there is a complex relative motion and friction between the slide rail 7 of the limit plate 6 and the pulley 10 during the rotation of the material plate 5, a good lubrication effect can be ensured, thereby reducing the friction resistance between the components, reducing wear, and extending the service life of the hydraulic shearing machine. At the same time, it also helps to improve the stability and accuracy of material rotation, ensuring the stable operation and processing accuracy of the entire shearing machine.

[0088] See also Figure 4 The present invention provides an embodiment: a multi-axis collaborative precision positioning hydraulic shearing machine, an oil supply assembly is provided on one side of the oil storage tank 15, and the oil supply assembly is used to transport lubricating oil into the oil storage tank 15.

[0089] The oil supply assembly includes an oil supply pipe 20 provided on one side of the oil storage tank 15, and one end of the oil supply pipe 20 passes through the display table 2;

[0090] A fixing groove 21 is provided inside the placing table 2, and the fixing groove 21 is located on the outside of the limiting groove 8. An oil storage tank 22 is provided inside the fixing groove 21, and an oil suction pipe 23 is provided through the side of the oil storage tank 22. A water pump 1 is provided at one end of the oil suction pipe 23, and a main pipe is provided at the output end of the water pump 1, and the main pipe is provided on one side of the oil supply pipe 20.

[0091] An oil inlet pipe 1 is provided through the top of the oil storage tank 22 , a water pump 2 is provided on the top of the oil inlet pipe 1, an oil inlet pipe 2 is provided at one end of the water pump 2, and the oil inlet pipe 2 passes through the side wall of the display table 2.

[0092] Furthermore, an oil supply pipe 20 is provided on one side of the oil storage tank 15, and one end of the oil supply pipe 20 passes through the placing table 2. The oil supply pipe 20 can establish a lubricating oil delivery channel from the oil storage tank 22 inside the placing table 2 to the oil storage tank 15 in the roller shaft 9.

[0093] A fixed groove 21 is provided inside the display table 2 for accommodating the oil storage tank 22. The fixed groove 21 is located outside the limiting groove 8. An oil suction pipe 23 is provided on the side of the oil storage tank 22. The oil suction pipe 23 extends deep into the oil storage tank 22, with one end near the bottom, ensuring that the lubricating oil can be effectively absorbed under different liquid level conditions. One end of the oil suction pipe 23 is connected to water pump 1, which serves as the power source. When the hydraulic shearing machine detects that the amount of lubricating oil in the oil storage tank 15 is insufficient during operation, water pump 1 starts to work. By generating suction, it draws the lubricating oil from the oil storage tank 22 through the oil suction pipe 23 and delivers it to the main pipe at its output end.

[0094] The main pipe is connected to the oil supply pipe 20, so that the extracted lubricating oil can flow further along the oil supply pipe 20 to the oil storage tank 15, thereby replenishing the lubricating oil in the oil storage tank 15. After the hydraulic shearing machine has been running continuously for a long time, as the lubrication between the roller 9 and the pulley 10 is continuously consumed, the lubricating oil level in the oil storage tank 15 gradually decreases. When the liquid level reaches the lower limit of the lubricating oil, the control system will trigger the water pump to start and begin replenishing lubricating oil to the oil storage tank 15 until the liquid level returns to the normal range.

[0095] To facilitate the replenishment of lubricating oil into the oil tank 22, an oil inlet pipe 1 is provided through the top of the oil tank 22. The top of the oil inlet pipe 1 is connected to a water pump 2, one end of which is connected to the oil inlet pipe 2. The oil inlet pipe 2 also extends through the side wall of the display table 2. When lubricating oil is needed in the oil tank 22, an external lubricating oil source is connected to the oil inlet pipe 2 via a pipe. After starting the water pump 2, the lubricating oil is pumped into the oil tank 22 through the oil inlet pipe 2 and the oil inlet pipe 1 under the pressure generated by the water pump 2. This arrangement makes the lubricating oil replenishment process more convenient and efficient. Whether it is regular refueling during routine maintenance of the hydraulic shearing machine or emergency replenishment of lubricating oil when the liquid level in the oil tank 22 is too low, refueling can be completed quickly. Furthermore, the pipelines of the oil inlet pipe 1 and the oil inlet pipe 2 are equipped with auxiliary devices, including valves for controlling the flow rate of lubricating oil in and out and starting and stopping operations, and filters for filtering out impurities that may be mixed in during the lubricating oil replenishment process, preventing impurities from entering the oil tank 22 and affecting the normal operation of the entire lubrication system.

[0096] See also Figure 1 、 Figure 2 and Figure 3 The present invention provides an embodiment of a multi-axis coordinated precise positioning hydraulic shearing machine, wherein a protective body 24 is provided on the top of the shearing machine body 1, and the protective body 24 is located outside the feed moving module, the placing table 2 and the material rotating module;

[0097] The front and back sides of the protection body 24 are provided with a feed inlet and a discharge outlet.

[0098] A hydraulic rod 1 25 and a hydraulic rod 2 26 are embedded in the top wall of the protective body 24, and the hydraulic rod 2 26 is located in front of the hydraulic rod 1 25;

[0099] The output end of the hydraulic rod 1 25 is provided with a fixing plate 27;

[0100] A knife seat 28 is provided at the output end of the hydraulic rod 26 , and a shearing knife 3 is provided at the bottom of the knife seat 28 .

[0101] Furthermore, the protective body 24 is located outside the feed movement module, the display table 2, and the material rotation module, providing an effective protective barrier for the components inside the hydraulic shearing machine and the operators outside. The feed and discharge ports on the front and back of the protective body 24 ensure that materials can enter and exit the hydraulic shearing machine for shearing while minimizing the risk of foreign matter entering the hydraulic shearing machine, preventing damage to internal operating components or interference with the normal operation of the hydraulic shearing machine.

[0102] Hydraulic rod 1 25 and hydraulic rod 2 26 are embedded in the top wall of the protective body 24. The output end of hydraulic rod 1 25 is connected to a fixed plate 27. During the shearing process, the fixed plate 27 plays an important auxiliary fixing role. After the material is placed on the material plate 5 and adjusted to the appropriate shearing position through the feed movement module and the material rotation module, hydraulic rod 1 25 drives the fixed plate 27 to move downward, pressing the material tightly against the material plate 5 to prevent the material from shifting or shaking under the action of the shearing force, thereby ensuring the accuracy and quality of the shearing. The output end of hydraulic rod 26 is connected to the knife holder 28, and the shearing knife 3 is installed at the bottom of the knife holder 28. Hydraulic rod 26 is the direct power source for the shearing action. When the hydraulic shearing machine receives the shearing command, the hydraulic system provides powerful power to hydraulic rod 26, causing it to push the knife holder 28 to drive the shearing knife 3 downward and move rapidly, accurately shearing the material.

[0103] The coordinated operation of hydraulic rods 1 (25) and 2 (26) is key to achieving high-quality shearing. Hydraulic rod 1 (25) secures the material before hydraulic rod 2 (26) performs the shearing action. During the shearing process, the pressure and speed of both rods are dynamically adjusted based on the material's material, thickness, and other characteristics. For example, thicker, harder metal sheets require greater shearing force. In this case, the hydraulic system will increase the pressure output of hydraulic rod 2 (26) accordingly, while hydraulic rod 1 (25) also provides a stronger holding force to ensure a smooth shearing process and guarantee a smooth, dimensionally accurate shear surface.

[0104] Further, the use of hydraulic shearing machine is as follows:

[0105] S1. Place the material to be sheared on the material plate 5 of the material rotation module;

[0106] S2, moving the material to the position to be sheared through the feeding moving module;

[0107] S3. Adjust the angle of the material through the material rotation module;

[0108] S4: After the material feed positioning and angle adjustment are completed, the material is sheared. After the shearing is completed, S1-S4 are repeated for the next shearing.

[0109] Furthermore, in S2, the following steps are also included:

[0110] S21, start the execution motor 2 of the feeding movement module, and measure the position of the placement table 2 in the feeding direction in real time through the displacement sensor 1 inside the slider 14 according to the length of the sheared material. When the shearing position is reached, the execution motor 2 stops running;

[0111] S22. During the feeding movement process, the second position sensor, the speed sensor, and the operation status monitoring sensor continuously monitor the rotation position, rotation speed, temperature, and vibration parameters of the second actuator motor;

[0112] S23. At the same time, the laser distance sensor of the material rotation module measures the distance between the edge of the material plate 5 and the placement table 2 in real time;

[0113] In S3, the following steps are also included:

[0114] S31. Start the actuator motor 1 of the material rotation module, drive the vertical reducer 4, and then rotate the material plate 5. Adjust the angle of the material according to the shearing requirements, and measure the rotation angle through the position sensor 2 outside the actuator motor 1;

[0115] S32. During the rotation process, the pressure sensor on the surface of the pulley 10 monitors the pressure change in real time, and the torque sensor and the speed sensor of the vertical reducer 4 monitor the torque and speed.

[0116] Working Principle: Executing Motor 1 provides rotational power. After torque and speed are adjusted by the vertical reducer 4, the material plate 5 is rotated via the rotating shaft to adjust the material angle. Position Sensor 2 on its outer side accurately provides feedback on the rotational position of executing Motor 1, thereby precisely controlling the rotation angle of the material plate 5. When cutting materials at a specific angle, the operation of executing Motor 1 can be adjusted in real time based on the comparison between the preset angle parameters and the actual measured position. The torque sensor and speed sensor monitor the output parameters of the vertical reducer 4 to ensure appropriate power is provided and the power of executing Motor 1 can be adjusted based on the material conditions, ensuring stable, accurate, and overload-free material rotation. A laser rangefinder monitors the distance between the edge of the material plate 5 and the display table 2 in real time to prevent collisions with other components during rotation, ensuring safe and accurate material rotation. A pressure sensor on the surface of pulley 10 monitors the pressure of the material placed on the material plate 5 during rotation or movement. Abnormal pressure can indicate unstable placement or a jammed material, allowing for timely adjustments or inspections.

[0117] The second execution motor drives the ball screw 12 to rotate. The ball screw 12 cooperates with the slider 14 to convert the rotational motion of the motor into the linear motion of the slider 14, thereby driving the horizontal movement of the display table 2. The displacement sensor 1 in the slider 14 measures the position of the display table 2 in the feeding direction in real time, providing a basis for accurate feeding positioning, ensuring that the second execution motor stops running when the preset shearing position is reached, and meeting the shearing requirements of materials of different lengths. The second position sensor, the speed sensor and the operation status monitoring sensor monitor the operation status of the second execution motor. The second position sensor can calculate the position of the slider 14 and the display table 2 by monitoring the rotation of the ball screw 12 to achieve accurate feeding positioning; the speed sensor adjusts the speed of the second execution motor according to the characteristics of the plate to ensure smooth and efficient feeding; the operation status monitoring sensor monitors the temperature and vibration of the motor, and alarms to prompt maintenance in case of abnormality, ensuring stable operation of the motor and reliable and accurate feeding.

[0118] The oil reservoir 15 stores lubricating oil, and sponge 17 is placed in the fixed cylinder 16 and located at the top and bottom of the oil reservoir 15, which can absorb and store lubricating oil. When the hydraulic shearing machine is running and the relative movement between the roller 9 and the pulley 10 generates pressure changes, the lubricating oil in sponge 17 slowly seeps out to the contact area. Sponge 2 18 in the pulley 10 corresponds to sponge 17 in position. Through capillary action and pressure difference, it absorbs lubricating oil from sponge 17 and distributes it to the contact surface between the pulley 10 and the slide rail 7, achieving precise and continuous lubrication, reducing friction and wear of the components, ensuring smooth and accurate material rotation, and extending the life of the hydraulic shearing machine. In the oil supply component, when water pump 1 is working, it draws lubricating oil from the oil tank 22 through the oil suction pipe 23 and transports it to the oil reservoir 15 through the main pipe and oil supply pipe 20, replenishing the lubricating oil in the oil tank 15 and maintaining the balance of the lubrication system. Oil inlet pipe 1, water pump 2, and oil inlet pipe 2 are used to replenish lubricating oil from the outside to the oil tank 22 to ensure that the entire lubrication system has an adequate oil supply.

[0119] The protective body 24 covers the key components within the hydraulic shearing machine, ensuring material flow through the inlet and outlet, preventing foreign matter from entering and damaging the shearing machine and ensuring operator safety. Hydraulic rod 1 25 drives the fixed plate 27, pressing the material against the material plate 5 during shearing to prevent material displacement from affecting shearing accuracy. Hydraulic rod 26 drives the blade holder 28, which moves the shear blade 3 up and down to shear the material. The hydraulic system adjusts the pressure, speed, and other parameters of hydraulic rods 1 25 and 2 26 based on the material's material and thickness, ensuring a smooth shearing process and a smooth, precise shear surface.
