Description

Technical Field

[0001] This utility model relates to the field of shearing machine technology, and in particular to a feeding device for a shearing machine. Background Technology

[0002] Hot-rolled stainless steel sheets are widely used in industrial production due to their good plasticity and the fact that they are mostly in medium and thick plate form. However, they also have characteristics such as relatively low strength, poor surface quality, easy oxidation and low smoothness. This puts specific requirements on the precision and stability of their processing and cutting equipment. In the processing and cutting of hot-rolled stainless steel sheets, the cross-cutting machine is the core equipment, which can achieve precise cutting of the sheet and meet the processing needs of different lengths and sizes. Therefore, it is widely used in the industry. To improve the adaptability and processing quality of cross-cutting machines, relevant technical personnel have carried out numerous improvement studies. For example, Chinese patent publication number CN218224842U discloses an adjustable cross-cutting machine for hot-rolled stainless steel plates. This equipment, through the setting of a cutting mechanism including a dual-axis motor, electric rod, bevel gear set and lead screw, realizes the adjustment of the cutting length, and can adjust the cutting for different stainless steel plate sizes to obtain products of different length specifications. Another Chinese patent, publication number CN222725584U, discloses an adjustable cross-cutting machine for processing cold-rolled stainless steel plates. With the help of a relative movement mechanism and a guide movement mechanism, it can clamp and drive stainless steel plates of different widths to move the plates. At the same time, the limiting guide rollers realize the limiting guidance to reduce the friction of the plate side. With the help of the clamping mechanism, it avoids the plate curling and warping during cross-cutting, thus improving the processing quality to a certain extent. However, existing cross-cutting machines still have significant defects and shortcomings when actually applied to the processing of hot-rolled stainless steel sheets. On the one hand, the feeding transmission structure of existing devices mostly uses limiting guide rollers for side limiting, lacking a bottom conveying guide limiting structure. During the conveying of the steel sheet or steel plate to be cut, the bottom of the plate is prone to directly contacting the top of the equipment base, resulting in significant friction. This not only leads to poor overall stability during conveying and increases the load on the drive motor, but may also cause friction scratches on the bottom of the steel sheet, affecting the surface quality of the product. On the other hand, existing devices cannot flexibly adapt to steel sheets of different thicknesses. During the clamping process, the top and bottom of the steel sheet lack effective limiting structures, which easily leads to bending and undulation of the steel sheet during the cutting operation, thus affecting the cutting accuracy and making it difficult to meet the actual needs of high-quality processing of hot-rolled stainless steel sheets. Therefore, it is urgent to improve the design of existing cross-cutting machines to address the above-mentioned problems and enhance their applicability and processing quality in the processing of hot-rolled stainless steel sheets. Utility Model Content

[0003] To address the aforementioned problems, this invention proposes a feeding device for a cross-cutting machine, which more accurately solves the problems described above.

[0004] This utility model is achieved through the following technical solution: This utility model proposes a feeding device for a cross-cutting machine, including a base frame, with support legs fixedly installed at the four corners of the top of the base frame, a top frame fixedly installed on the top of the support legs, feeding and conveying mechanisms fixedly installed on both sides of the top frame, and a cross-cutting mechanism fixedly installed in the middle of the top of the top frame. The feeding and conveying mechanism includes a fixed base, which is fixedly installed on the middle of both sides of the top frame. An electric push rod is fixedly installed on the outer side of the fixed base. The output end of the electric push rod passes through the top frame and is fixedly installed with a conveying module. A clamping module is fixedly installed in the middle of the conveying module.

[0005] Furthermore, the conveying module includes a guide rail, which is fixedly installed on the inner output end of the electric push rod. The clamping module is disposed on the inner side of the guide rail. Conveying frames are fixedly installed on both sides of the guide rail. Side drive rollers are rotatably connected to the inner side of the conveying frames in a linear arrangement at equal intervals. Second motors are fixedly installed at both ends and the middle of the top of the conveying frames. The output end of the second motor is connected to the bottom of the corresponding side drive roller through a coupling.

[0006] Furthermore, a support guide rod is fixedly installed on the outer end of the outer side of the conveying frame. The outer end of the support guide rod penetrates through the top frame, and the support guide rod and the top frame are slidably connected.

[0007] Furthermore, the clamping module includes a lead screw and a first motor. The first motor is fixedly installed on the top of the guide rail. The lead screw is rotatably connected to the inside of the guide rail. The two ends of the lead screw have opposite thread directions. Both ends of the lead screw are threadedly connected to sliders. The sliders are slidably connected to the two ends inside the guide rail. A guide clamping assembly is fixedly installed on the inner side of the slider.

[0008] Furthermore, the guide clamping assembly includes a connecting arm, which is fixedly installed on the inner side of the sliders that are close to each other. A concave frame is fixedly installed on the inner end of the connecting arm, and a clamping guide roller is rotatably connected to the inner side of the concave frame.

[0009] Furthermore, the inner side of the connecting arm and the concave frame is provided with a cutting pre-reserved groove, and the cutting end of the cross-cutting mechanism is movable inside the cutting pre-reserved groove.

[0010] Furthermore, the transverse cutting mechanism includes a support frame, which is fixedly installed at the top center of the top frame. A mounting base is fixedly installed at the top center of the support frame. A hydraulic cylinder is fixedly installed at the top of the mounting base. A pressure plate is fixedly installed at the bottom output end of the hydraulic cylinder through the mounting base. A transverse shearing blade is fixedly installed at the bottom of the pressure plate. The transverse shearing blade moves within the pre-cut groove.

[0011] The beneficial effects of this utility model are: 1. During the application of this technical solution, a multi-dimensional clamping structure is set up to achieve all-round positioning of the board from top to bottom and front to back. Laterally, the electric push rod drives the conveying frame to adjust the spacing of the side drive rollers, so that the side drive rollers fit against the front and back sides of the board to form a lateral clamping. In the longitudinal direction, the first motor drives the guide clamping group to move, so that the clamping guide rollers are in close contact with the side of the board to strengthen the longitudinal positioning. At the same time, the side drive rollers and the clamping guide rollers work together to indirectly limit the board in the vertical direction, so that the board will not shift in the front and back or move up and down during use. Even during the conveying process, it can maintain a stable posture and avoid the board tilting caused by inadequate clamping. This achieves the effect of improving the stability and positioning accuracy of the board conveying, and solves the problem of board offset caused by only one-sided limiting and incomplete clamping in the existing technology. 2. During the application of this technical solution, the linkage clamping design optimizes the synergy of clamping on the upper, lower, front, and rear sides. The side drive rollers for lateral clamping and the clamping guide rollers for longitudinal clamping move synchronously. During the width adjustment stage, the side drive rollers first initially position the front and rear sides of the plate, and then the clamping module precisely locks the longitudinal posture of the plate. During cutting, the two maintain continuous clamping force, which, together with the limiting effect of the pre-reserved cutting groove on the cutting area of ​​the plate, ensures that the plate is in an all-round clamping state from conveying to cutting during use. It will not bend or shift due to cutting force, ensuring that the cutting cut is flat and the dimensions are accurate. This achieves the effect of improving cutting quality and processing consistency, and solves the problems of disconnection between clamping and cutting links and easy deformation of plate during cutting in the prior art.

[0014] 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. Example 1

[0015] A feeding device for a cross-cutting machine includes a base frame 1, with support legs 4 fixedly installed at the four corners of the top of the base frame 1, a top frame 5 fixedly installed on the top of the support legs 4, a feeding conveying mechanism 2 fixedly installed on both sides of the top frame 5, and a cross-cutting mechanism 3 fixedly installed in the middle of the top of the top frame 5. The feeding and conveying mechanism 2 includes a fixed base 21, which is fixedly installed on the middle of both sides of the top frame 5. An electric push rod 25 is fixedly installed on the outer side of the fixed base 21. The output end of the electric push rod 25 passes through the top frame 5 and is fixedly installed on the conveying module 23. A clamping module 24 is fixedly installed in the middle of the conveying module 23. During the application of this device, through the cooperative structure of the base frame 1, support legs 4, top frame 5, feeding and conveying mechanism 2 and cross-cutting mechanism 3, it is possible to first activate the electric push rod 25 on the outer side of the fixed base 21 in the feeding and conveying mechanism 2 according to the specifications of the material to be processed. When the electric push rod 25 runs, it pushes the conveying module 23 to move, adjusting the matching position between the conveying module 23 and the material. The clamping module 24 in the conveying module 23 moves accordingly. The synchronous action of the feeding and conveying mechanism 2 clamps and fixes the sheet metal, ensuring that the sheet metal maintains a stable posture during the conveying process. Then, the feeding and conveying mechanism 2 conveys the clamped and fixed sheet metal to the underside of the cross-cutting mechanism 3, where the cross-cutting mechanism 3 cuts and processes the sheet metal. Throughout the process, the base frame 1 provides a stable foundation support for the device, and the support leg 4 connects the base frame 1 and the top frame 5, ensuring the installation stability of the top frame 5. The top frame 5 provides a reliable mounting carrier for the feeding and conveying mechanism 2 and the cross-cutting mechanism 3, enabling the various components of the device to work together to achieve stable feeding and precise cutting of the sheet metal, effectively improving the stability and efficiency of the sheet metal processing process. This solves the problems of unstable sheet metal feeding and inaccurate cutting positioning that may exist in the prior art, and meets the basic requirements of sheet metal processing.

[0016] Combination Figures 1-5 As shown, the conveying module 23 includes a guide rail 231, which is fixedly installed on the inner output end of the electric push rod 25. The clamping module 24 is disposed on the inner side of the guide rail 231. Conveying frames 232 are fixedly installed on both sides of the guide rail 231. Side drive rollers 233 are rotatably connected to the inner side of the conveying frame 232 in a linear arrangement at equal intervals. Second motors 234 are fixedly installed at both ends and the middle of the top of the conveying frame 232. The output end of the second motor 234 is connected to the bottom of the corresponding side drive roller 233 through a coupling. Supporting guide rods 235 are fixedly installed on the outer ends of the outer side of the conveying frame 232. The outer ends of the supporting guide rods 235 penetrate the top frame 5, and the supporting guide rods 235 and the top frame 5 are slidably connected.

[0017] In the above-described embodiments of this application, during the application of this device, by setting up a guide rail 231, a conveying frame 232, a side drive roller 233, a second motor 234, and a support guide rod 235 in the conveying module 23, the conveying frame 232 adjusts its position synchronously with the guide rail 231 when the electric push rod 25 pushes the guide rail 231 to move to adapt to the specifications of the sheet material. The support guide rod 235 slides along the top frame 5 during the movement of the conveying frame 232 to ensure that the conveying frame 232 does not deviate when it moves. After the position is adjusted, the second motor 234 at the top of the conveying frame 232 is started. The output end of the second motor 234 drives the side drive roller 233 at the corresponding position to rotate through a coupling. Because the side drive roller 233 is in The conveying frame 232 has linearly arranged materials at equal intervals on its inner side. The rotating side drive rollers 233 can drive the material to be conveyed smoothly. At the same time, the clamping module 24 can cooperate to limit the material on the inner side of the guide rail 231 to ensure the stability of the material conveying direction. Throughout the process, the guide rail 231 provides the installation and operation basis for the clamping module 24, and the conveying frame 232 provides support for the side drive rollers 233 and the second motor 234. The side drive rollers 233 achieve uniform material conveying through synchronous rotation. The support guide rod 235 improves the stability of the conveying frame 232 during movement and operation, effectively avoiding deviation or jamming during material conveying, improving the smoothness and accuracy of material feeding and conveying, and meeting the requirements of subsequent processing for the material conveying state. Example 2

[0018] Combination Figures 4-5 As shown, the clamping module 24 includes a lead screw 241 and a first motor 242. The first motor 242 is fixedly mounted on the top of the guide rail 231. The lead screw 241 is rotatably connected to the inside of the guide rail 231. The two ends of the lead screw 241 have opposite thread directions. Both ends of the lead screw 241 are threadedly connected to sliders 243. The sliders 243 are slidably connected to the two ends inside the guide rail 231. A guide clamping assembly 244 is fixedly mounted on the inner side of the sliders 243. The guide clamping assembly 244 includes a connecting arm 2441. The connecting arm 2441 is fixedly mounted on the inner side of the sliders 243 that are close to each other. A concave frame 2442 is fixedly mounted on the inner end of the connecting arm 2441. The inner side is rotatably connected to a clamping guide roller 2443. The inner side of the connecting arm 2441 and the concave frame 2442 is provided with a cutting reserved groove 2444. The cutting end of the cross-cutting mechanism 3 is movable inside the cutting reserved groove 2444. The cross-cutting mechanism 3 includes a mounting frame 31, which is fixedly installed in the middle of the top of the top frame. A mounting base 32 is fixedly installed in the middle of the top of the mounting frame 31. A hydraulic cylinder 33 is fixedly installed on the top of the mounting base 32. A pressure plate 34 is fixedly installed through the mounting base 32 at the bottom output end of the hydraulic cylinder 33. A cross-cutting blade 35 is fixedly installed at the bottom of the pressure plate 34. The cross-cutting blade 35 is movable inside the cutting reserved groove 2444.

[0019] In the above-described embodiments of this application, during the application of this device, by setting the lead screw 241, first motor 242, slider 243, and guide clamping group 244 in the clamping module 24, and the frame 31, mounting base 32, hydraulic cylinder 33, pressure plate 34, and cross-cutting blade 35 in the cross-cutting mechanism 3, the first motor 242 is started first during use. The first motor 242 drives the lead screw 241 inside the guide rail 231 to rotate. Because the threads at both ends of the lead screw 241 turn in opposite directions, the sliders 243 at both ends slide inside the guide rail 231. The guide clamping group 244 inside the slider 243 moves synchronously. The connecting arm 2441 in the guide clamping group 244 drives the concave frame 2442 to move until the clamping guide roller 2443 inside the concave frame 2442 is in contact with the plate, thereby achieving clamping and limiting of the plate. When the plate is conveyed to the designated position, cross-cutting is started. The hydraulic cylinder 33 of mechanism 3 pushes the pressure plate 34 downward, and the cross-cutting blade 35 at the bottom of the pressure plate 34 moves downward accordingly. The cross-cutting blade 35 moves within the cutting groove 2444 inside the connecting arm 2441 and the concave frame 2442 to cut the plate. During the process, the lead screw 241 realizes the bidirectional movement of the slider 243 through the reverse thread. The clamping guide roller 2443 can rotate slightly with the plate to reduce friction when clamping. The cutting groove 2444 provides the cross-cutting blade 35 with room to move and avoids interference with other components. The frame 31 and the mounting base 32 provide stable support for the hydraulic cylinder 33. The pressure plate 34 ensures that the cross-cutting blade 35 is subjected to uniform force, effectively ensuring the stability of the plate clamping and the accuracy of the cutting, avoiding the plate shifting or component collision during cutting, improving the quality and safety of plate processing, and meeting the needs of precise plate cutting.

[0020] The working principle and advantages of this utility model are as follows: During the application of this device, when processing hot-rolled stainless steel plates, the electric push rod 25 in the feeding and conveying mechanism 2 is first started according to the width of the hot-rolled stainless steel plate to be processed. When the electric push rod 25 runs, it pushes the guide rail 231 to move. The conveying frame 232 moves synchronously with the guide rail 231. When the side drive roller 233 inside the conveying frame 232 is matched with the width of the plate, the electric push rod 25 stops running. The support guide rod 235 plays a guiding and stabilizing role during the movement of the conveying frame 232, preventing the conveying frame 232 from deviating. At the same time, the bellows cover set on the outside of the guide rail 231 is connected to the slider 243 and can move and extend with the slider 243 to completely wrap the lead screw 241, preventing dust and metal debris generated during the processing from entering the inside of the guide rail 231 and adhering to the surface of the lead screw 241, and preventing the lead screw 241 from being jammed by foreign objects and affecting the transmission accuracy. After the width adjustment is completed, the first motor 242 in the clamping module 24 is started. When the first motor 242 runs, it drives the lead screw 241 to rotate. Since the threads at both ends of the lead screw 241 turn in opposite directions, the sliders 243 at both ends slide in opposite directions inside the guide rail 231. The guide clamping group 244 moves synchronously with the slider 243. When the guide clamping group 244 is in contact with the side of the plate, the first motor 242 is turned off, realizing the longitudinal clamping and positioning of the plate. The connecting arm 2441 in the guide clamping group 244 connects the slider 243 and the concave frame 2442. The clamping guide roller 2443 on the inner side of the concave frame 2442 contacts the side of the plate, further enhancing the longitudinal limiting effect on the plate. The cutting reserved groove 2444 opened on the inner side of the connecting arm 2441 and the concave frame 2442 provides space for the subsequent cutting operation of the cross-cutting mechanism 3. The hot-rolled stainless steel sheet to be processed is placed on the conveying module 23. The second motor 234 is started. When the second motor 234 is running, it drives the side drive roller 233 to rotate through the coupling. When the side drive roller 233 rotates, it drives the sheet to move along the conveying direction, realizing the feeding and conveying of the sheet. When the sheet is conveyed to the designated position below the cross-cutting mechanism 3, the second motor 234 is turned off and the conveying module 23 stops running. At this time, the cross-cutting mechanism 3 is started. When the hydraulic cylinder 33 runs, it pushes the pressure plate 34 to move downward. The cross-cutting blade 35 moves downward synchronously with the pressure plate 34. The cross-cutting blade 35 cuts the plate during the process of moving downward inside the cutting reserved groove 2444. After the cutting is completed, the hydraulic cylinder 33 drives the cross-cutting blade 35 to reset. The second motor 234 is started again. The conveying module 23 conveys the cut plate to the designated position. At the same time, the new plate to be processed enters the feeding conveying mechanism 2. Repeating the above operation can realize continuous processing. The base frame 1 provides basic support for the entire device. The support leg 4 connects the base frame 1 and the top frame 5. The top frame 5 provides the mounting carrier for the feeding conveying mechanism 2 and the cross-cutting mechanism 3. The mounting frame 31 provides support for the mounting base 32. The mounting base 32 provides the mounting position for the hydraulic cylinder 33. The pressure plate 34 connects the hydraulic cylinder 33 and the cross-cutting blade 35. This device achieves more precise plate positioning by adjusting the width before longitudinal clamping. The bellows cover prevents contamination of the lead screw 241, extending its service life. The side drive roller 233 transports the plate, ensuring it only contacts the roller during transport, preventing friction between the plate's bottom and the fixed structure, reducing the load on the second motor 234, and preventing scratches on the plate's bottom. The pre-cutting groove 2444 not only provides space for the cross-cutting blade 35 but also positions the plate for cutting, improving cutting accuracy. The hydraulic cylinder 33 moves the cross-cutting blade 35 with stable cutting force, enabling the cutting of hot-rolled stainless steel plates of varying thicknesses. Furthermore, the cutting efficiency is relatively high; the independent control of the first motor 242 and the second motor 234 allows for separate adjustment of clamping and conveying operations, improving the flexibility of the device operation and better adapting to different processing needs; the electric push rod 25 drives the conveying module 23 to move as a whole, further expanding the device's adaptability range for plate sizes; the clamping guide roller 2443 and the side drive roller 233 work together during the cutting process to keep the plate stable, avoiding bending and undulation of the plate during cutting, and further ensuring cutting accuracy. Therefore, through the coordinated cooperation of various structures, this device effectively solves many problems existing in the feeding device of the existing cross-cutting machine during use, and improves the quality and efficiency of hot-rolled stainless steel plate processing.

[0021] During the application of this device, if the user wants to save on operating costs, a second motor 234 can be used. The second motor 234 can then drive each side drive roller 233 synchronously through a gear transmission structure, sprocket transmission structure, or worm gear transmission structure. The specific choice of application can be made flexibly according to the requirements. When multiple second motors 234 are used for driving transmission, a synchronous start module can be set up. The specific synchronous operation principle is as follows: the control module generates a synchronous command and sends it to each motor driver. At the same time, a rotary encoder is set on the motor to collect the actual running position and speed in real time, or the rotation speed is fed back through a Hall sensor. After comparing these feedback data with the command value to calculate the deviation, the output signal is dynamically adjusted to eliminate the deviation. Finally, multiple motors maintain a preset cooperative relationship in terms of speed, position, or torque. The above-mentioned synchronous drive technology and transmission structure, sprocket transmission structure, or worm gear transmission structure are all conventional designs of the prior art. In this technical solution, a PLC controller (model S7-1200, specification CPU1214CDC / DC / DC, 14 inputs DC24V, 10 outputs DC24V) is selected as the controller and installed inside the base frame 1. The controller is equipped with a display screen. The circuit system is powered by a 24V DC switching power supply (specification 500W, input AC220V, output DC24V / 20A). The switching power supply is fixed inside the base frame 1. The first motor 242 is a stepper motor (model 57HS22, rated current 3A, step angle 1.8°). The motor is equipped with an encoder (model E6B2-CWZ6C, resolution 1000 lines), which is connected to the pulse output terminal and direction signal terminal of the controller through wires. The encoder signal output terminal is connected to the high-speed counting terminal of the controller. The second motor 234 is a servo motor (model HG-SR1024, rated power 1kW, rated speed 3000r / min). The motor is equipped with an encoder (model OSE104, resolution 131072p / r), and a driver (model MR-J4-10A) is connected to the controller via an EtherCAT bus. The encoder signal is fed back to the driver to form a closed-loop control. The driver's power input is connected to a switching power supply. The electric actuator 25 is a DC electric actuator 25 (model DTZ300, rated voltage 24V, thrust 300N). Its control terminal is connected to the controller's output terminal via a relay module (model G2R-1-E, rated voltage 24V), and its power input terminal is connected to a switching power supply. The solenoid valve (model 4V210-08, rated voltage 24V) of the hydraulic cylinder 33 has its control terminal connected to the controller's output terminal, and its power input terminal connected to a switching power supply. The bellows cover on the guide rail 231 does not require a circuit connection. Gearbox reducers are installed at both the first motor 242 and the second motor 234. Motor 242 is equipped with a 57K150 reducer (reduction ratio 5:1); the second motor 234 is equipped with a 100K reducer (reduction ratio 10:1). They are connected to the motor output shaft via a coupling. The circuit connections are as follows: the power supply output is connected to the controller, the first motor 242 driver, the second motor 234 driver, the relay module, and the power input of the solenoid valve; the controller output is connected to the pulse and direction terminals of the first motor 242 driver, the control terminal of the relay module, the control terminal of the solenoid valve, and the signal terminal of the display screen; the encoder signal terminal of the first motor 242 is connected to the high-speed counting terminal of the controller, and the encoder signal terminal of the second motor 234 is connected to its driver signal input terminal. The driver communicates with the controller via a bus; the power input terminal of the electric push rod 25 is connected to the power supply output terminal via the normally open contact of the relay module, forming a complete control loop. The controller programming enables coordinated action of all components. The encoder feedback signal allows the motor to flexibly adjust rotation and steplessly regulate speed. The gearbox reducer increases output torque and controls speed. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.

[0022] Of course, there may be other implementations of this utility model. Based on this implementation, other implementations obtained by those skilled in the art without any creative effort are all within the scope of protection of this utility model.
