Technical Field
[0001] This utility model belongs to the field of cutting machine technology, and specifically relates to a fully automatic hydraulic cutting machine. Background Technology
[0002] In the field of materials processing, hydraulic cutting machines are playing an increasingly important role as a key piece of equipment. Their working principle is based on a hydraulic drive system. Through the coordinated operation of the machine body, hydraulic system, electrical control system, and cutting mechanism, powerful pressure is generated. The hydraulic system, as the power source, drives the punch head of the cutting mechanism. With the help of the punching die, it can accurately cut various materials such as leather, rubber, plastic, and paper according to the pre-set shape and size. This equipment has outstanding advantages such as large cutting force, high precision, simple operation, high production efficiency, and good safety. It is widely used in many industries such as footwear, bags, clothing, automotive interiors, and electronics, and has become an indispensable part of the material processing process.
[0003] With the increasing demand for efficient and precise production in the industry, many new hydraulic cutting machines are emerging. For example, the composite fully automatic precision four-column hydraulic cutting machine disclosed in Chinese patent "CN213320334U" has an ingenious structural design. The equipment uses a base as a support foundation, and a transmission device is set at the center of the top of the base to assist in material feeding and improve the continuity of the production process. Multiple guide columns are fixedly connected to the periphery of the top of the base, which together with the top plate at the top, form a stable frame structure. The hydraulic cylinder connected to the center of the top plate drives the sliding plate to slide up and down along the guide columns through the piston rod. On the tool plate at the bottom of the sliding plate, a fixed blade responsible for conventional cutting is fixed at the center. The threaded rods and threaded sliders connected internally on both sides cooperate to adjust the position of the movable blade and thus control the size of the cut pieces. This design can directly cut out the required block-shaped EPE, effectively avoiding repeated cutting operations and significantly improving production efficiency.
[0004] However, a closer examination of the device's performance in practical applications reveals its limitations. During the punching process, the lack of positioning and clamping structures on both sides of the product makes the processed material prone to slippage when subjected to punching force. This slippage directly leads to deviations in the punching position, resulting in a large number of defective products and severely impacting production efficiency and product quality. This problem not only increases production costs but also reduces the company's competitiveness in the market. Therefore, developing a new type of hydraulic cutting machine with an efficient positioning and clamping structure to overcome the shortcomings of existing equipment and improve the stability and accuracy of the punching process has become an important issue that the current materials processing industry urgently needs to address.

[0008] The positioning and guiding mechanism includes a slide groove and a first motor. The slide groove is located at the top center of the top frame. A lead screw is rotatably connected inside the slide groove. The two ends of the lead screw have opposite thread directions. A slider is threaded to both ends of the lead screw. A drive assembly is fixedly installed on the top of the slider. The first motor is fixedly installed in the middle of one side of the frame. The output end of the first motor is connected to the end of the lead screw.
[0009] As a preferred technical solution, the drive assembly includes a side frame, which is fixedly installed on the top of the slider. A clamping frame is fixedly installed on the inner end of the side frame.

[0010] As a preferred technical solution, the power unit includes a worm gear and a second motor. The second motor is fixedly installed on the top of the rear end of the clamping frame. The worm gears are linearly arranged at equal intervals and rotatably connected to the top of the clamping frame. A worm is fixedly installed at the output end of the second motor. The worm and the worm gear are connected by a transmission. The bottom of the worm gear is connected to the top of the transmission guide wheel.
[0011] As a preferred technical solution, the blanking mechanism includes a mounting rail, on which the bottom output end of a hydraulic cylinder is fixedly mounted. A mounting plate is slidably connected inside the mounting rail. A mounting screw is threadedly connected to one top end of the mounting rail. The end of the mounting screw passes through the mounting rail and is threadedly connected to the top of the mounting plate. A blanking cutter is fixedly mounted in the middle of the bottom of the mounting plate. The blanking cutter is positioned at the gap of the transmission guide wheel. Pressing and fixing assemblies are fixedly mounted on both sides of the bottom of the mounting plate.
[0012] As a preferred technical solution, the pressing assembly includes a base plate, which is fixedly installed on both sides of the bottom of the mounting plate.

[0013] As a preferred technical solution, the top two ends of the pressure frame are fixedly installed with support shafts, the top of the support shafts penetrates through the substrate, and the support shafts and the substrate are slidably connected.
[0014] As a preferred technical solution, the side of the slider is convex, the internal cross-sectional shape of the groove is also convex, and wear-resistant pads are provided on the outer surface of the slider and the inner wall of the groove.
[0015] In summary, the present invention has the following main advantages:
[0016] Firstly, during operation, the blanking mechanism of this device can be activated by starting the hydraulic cylinder, which powerfully drives the blanking blade downwards to hydraulically cut the product on the support platform. During the downward movement of the blanking blade, the bottom two side pressure frames press against the top of the product for auxiliary positioning. The blanking blade and the pre-reserved blanking slot work together to accurately complete the blanking. Because the blanking blade is located in the gap of the transmission guide wheel, interference is avoided, ensuring smooth blanking. The telescopic spring adjusts the space between the pressure frame and the blanking blade, improving blanking stability and positioning effect, and ensuring the quality of the cutting process. When the blanking blade specifications do not meet the requirements, the mounting plate can be quickly pulled out by turning the mounting screw to remove and replace the blanking blade, enhancing the blanking quality, stability, and adaptability of the device, and flexibly handling diverse processing tasks. Secondly, this device, through the setting of a positioning and guiding mechanism, enables the first motor to be started during operation, driving the lead screw to rotate within the slide groove. Because the threads at both ends rotate in opposite directions, the two sliders slide relative to or away from each other, precisely adjusting the distance between the transmission guide wheels on the inner side of the clamping frame to achieve positioning of both sides of the product. The second motor is then started, driving the worm gear, which in turn drives the worm wheel and transmission guide wheels to rotate synchronously. The transmission guide wheels fit against both sides of the product, and the product is flexibly transferred through motor control. This mechanism can not only stably clamp products of different sizes and prevent slippage during punching, but also achieve automated transfer, greatly improving the stability and automation of punching processing, further enhancing production quality and efficiency, and meeting the needs of high-efficiency production.

[0022] Example
[0023] refer to Figures 1 to 4 This embodiment of a fully automatic hydraulic cutting machine includes a frame 1, a top frame 2 fixedly installed on the top of the frame 1, a hydraulic cylinder 3 fixedly installed on the top of the top frame 2, a punching mechanism 4 fixedly installed through the output end of the hydraulic cylinder 3 through the top frame 2, a support platform 5 fixedly installed on the lower inner side of the top frame 2, a punching reserved groove 6 opened in the middle of the top of the support platform 5, and a positioning guide mechanism 7 fixedly installed in the middle of the support platform 5.
[0024] The positioning and guiding mechanism 7 includes a slide 71 and a first motor 72. The slide 71 is located at the top center of the top frame 2. A lead screw 73 is rotatably connected inside the slide 71. The two ends of the lead screw 73 have opposite thread directions. Both ends of the lead screw 73 are threadedly connected to sliders 74. A drive assembly 75 is fixedly installed on the top of the sliders 74. The first motor 72 is fixedly installed in the middle of one side of the frame 1. The output end of the first motor 72 is connected to the end of the lead screw 73. In this fully automatic hydraulic cutting machine, all components work together to achieve efficient cutting. The frame 1 and the top frame 2 form a stable structure to support the equipment. When cutting is performed, the hydraulic cylinder 3 on the top of the top frame 2 is activated, and its output... The end pushes the punching mechanism 4 downward to cut the product on the top of the support platform 5. The punching reserved groove 6 in the middle of the support platform 5 cooperates with the punching mechanism 4 to ensure accurate cutting. Regarding the positioning and guiding mechanism 7, the first motor 72 located in the middle of one side of the frame 1 starts, and its output end drives the lead screw 73 to rotate in the slide groove 71 in the middle of the top of the top frame 2. Since the threads at both ends of the lead screw 73 turn in opposite directions, when rotating, the slider 74 connected by the threads at both ends will slide relative to or away from each other in the slide groove 71. The drive component 75 installed on the top of the slider 74 moves accordingly, thereby realizing the positioning and conveying of the product on both sides, ensuring the stability of the product during the cutting process, and providing support for efficient cutting.
[0025] refer to Figures 1-3The drive assembly 75 includes a side frame 751, which is fixedly mounted on the top of the slider 74. A clamping frame 752 is fixedly mounted on the inner end of the side frame 751. Transmission guide wheels 753 are rotatably connected at equal intervals on the inner side of the clamping frame 752. A power unit 76 is provided on the top of the clamping frame 752. The power unit 76 includes a worm gear 761 and a second motor 762. The second motor 762 is fixedly mounted on the top of the rear end of the clamping frame 752. The worm gears 761 are linearly arranged at equal intervals and rotatably connected to the top of the clamping frame 752. A worm 763 is fixedly mounted on the output end of the second motor 762. The worm 763 and the worm gear 761 are connected by a transmission. The bottom of the worm gear 761 is connected to the top of the transmission guide wheel 753. The drive assembly 75 of this fully automatic hydraulic cutting machine is mainly used for product positioning and conveying. In the positioning and guiding mechanism 7, the first motor 72 drives the lead screw 73 to rotate. The movement causes the slider 74 to slide within the slide groove 71, and the side frame 751 fixed to the top of the slider 74 moves accordingly. The clamping frame 752 at the inner end of the side frame 751 also moves synchronously, thereby adjusting the distance between the two clamping frames 752 to position the product on both sides. When the product needs to be transferred, the second motor 762 is started, and its output end drives the worm gear 763 to rotate. Since the worm gear 763 is connected to the worm wheels 761 arranged at equal intervals on the top of the clamping frame 752, the rotation of the worm gear 763 will drive all the worm wheels 761 to rotate synchronously. Since the bottom of the worm wheel 761 is connected to the top of the transmission guide wheel 753 on the inner side of the clamping frame 752, the rotation of the worm wheel 761 will drive the transmission guide wheel 753 to rotate. The transmission guide wheel 753 fits against the two sides of the product, thereby realizing the automated transfer of the product and ensuring that the product can be moved stably and accurately to the corresponding position during the cutting process.
[0026] refer to Figures 1-2The blanking mechanism 4 includes a mounting rail 41, on which the bottom output end of the hydraulic cylinder 3 is fixedly mounted. A mounting plate 42 is slidably connected inside the mounting rail 41. A mounting screw 43 is threadedly connected to one top end of the mounting rail 41, and the end of the mounting screw 43 passes through the top of the mounting rail 41 and the mounting plate 42. A blanking cutter 44 is fixedly mounted in the middle of the bottom of the mounting plate 42, positioned at the gap of the transmission guide wheel 753. Pressing and fixing assemblies 45 are fixedly mounted on both sides of the bottom of the mounting plate 42. Each pressing and fixing assembly 45 includes a base plate 451, which is fixedly mounted on both sides of the bottom of the mounting plate 42. A telescopic spring 452 is fixedly installed at the bottom of 451. A connecting shaft 453 is fixedly installed at the bottom of the telescopic spring 452. A pressure frame 454 is fixedly installed at the bottom of the connecting shaft 453. Support shafts 455 are fixedly installed at both ends of the top of the pressure frame 454. The top of the support shafts 455 penetrates through the base plate 451. The support shafts 455 and the base plate 451 are slidably connected. The side of the slider 74 is convex in shape. The internal cross-sectional shape of the slide groove 71 is also convex in shape. Wear-resistant pads are provided on the outer surface of the slider 74 and the inner wall of the slide groove 71. In the punching mechanism 4 of this fully automatic hydraulic cutting machine, when the hydraulic cylinder 3 is started, the bottom of the hydraulic cylinder 3... The output end drives the mounting rail 41 downwards, and the mounting plate 42, which is slidably connected inside the mounting rail 41, moves accordingly. The punching knife 44, fixed in the middle of the bottom of the mounting plate 42, moves downwards toward the product on the support table 5. The punching knife 44 is positioned at the gap of the transmission guide wheel 753 to avoid interference with the transmission guide wheel 753, thus achieving precise punching of the product. During the punching process, the pressing and fixing groups 45 on both sides of the bottom of the mounting plate 42 play an important role. As the mounting plate 42 moves downwards, the pressing frame 454 in the pressing and fixing group 45 contacts the top of the product first. The pressing frame 454 is connected to the telescopic spring 452 through the coupling shaft 453. The telescopic spring 452 provides cushioning and... The adaptive adjustment capability ensures that the pressure frame 454 can press the product tightly and stably. At the same time, the support shaft 455 slides in the base plate 451 to ensure that the pressure frame 454 presses down smoothly. When it is necessary to replace the punching knife 44, the mounting screw 43 at the top end of the mounting rail 41 is turned to disengage it from the mounting plate 42, and the mounting plate 42 can be pulled out from the mounting rail 41 to complete the replacement of the punching knife 44. The slider 74 and the slide groove 71 are both convex and have wear-resistant pads on their surfaces, which not only ensures that the slider 74 slides stably in the slide groove 71, but also reduces friction, ensuring that the entire punching mechanism 4 runs smoothly and improving the working efficiency and stability of the cutting machine.
[0027] Operating principle and advantages: The punching mechanism 4 equipped in this device greatly improves the quality of hydraulic cutting and the adaptability of the equipment. During the operation of the device, the hydraulic cylinder 3 is started. The powerful force generated by the hydraulic cylinder 3 pushes the punching knife 44 downward to perform hydraulic cutting on the product on the support table 5. During the downward movement of the punching knife 44, the pressure frames 454 on both sides of the bottom of the punching knife 44 are pressed against the top of the product. The close contact between the pressure frames 454 and the top of the product forms an auxiliary positioning to ensure the positional stability of the product during the punching process. As the hydraulic cylinder 3 continues to drive the punching knife 44 downward, the punching knife 44 cooperates with the pre-set punching groove 6 to accurately punch the product. Since the punching knife 44 is set at the gap position of the transmission guide wheel 753, it can effectively avoid the interference of the transmission guide wheel 753 and achieve good punching of the product.
[0028] During the punching process, the telescopic spring 452 plays an important role. The telescopic characteristics of the telescopic spring 452 can flexibly adjust the space between the reserved pressure frame 454 and the punching knife 44, which not only ensures the stability of the punching process, but also ensures the effect of pressing and positioning, thereby significantly improving the overall punching and cutting quality of this device. In addition, when the size of the punching knife 44 cannot meet the actual processing needs, the operator only needs to twist the mounting screw 43 to move the mounting screw 43 upward, so that the mounting plate 42 can be easily pulled out and removed from the mounting rail 41, realizing the quick replacement of the punching knife 44. This design enables this device to flexibly cope with different punching needs in actual use, significantly improving the overall punching and cutting quality, stability and adaptability.
[0029] The positioning and guiding mechanism 7 provides an efficient and stable solution for product positioning and conveying in this device. During device operation, the first motor 72 is started, and the first motor 72 drives the lead screw 73 to rotate. The lead screw 73 slides inside the slide groove 71, and the threads at both ends of the lead screw 73 rotate in opposite directions. This design allows the two sliders 74 to move back and forth in opposite directions inside the slide groove 71 as the lead screw 73 rotates. Through the flexible sliding of the sliders 74 in the slide groove 71, the spacing of the transmission guide wheels 753 inside the clamping frame 752 of this device can be precisely adjusted, thereby achieving precise positioning of both sides of the product to be punched.
[0030] After product positioning is completed, the second motor 762 is started, driving the worm gear 763 to rotate. The rotation of the worm gear 763 drives the various worm wheels 761 connected to it to rotate synchronously, which in turn drives all the transmission guide wheels 753 to operate synchronously. Since the transmission guide wheels 753 are in close contact with both sides of the product to be punched, the linkage control of the worm gear 763, worm wheels 761 and transmission guide wheels 753 by the second motor 762 can flexibly transfer the product to be punched back and forth. This design can not only stably clamp and limit products of different sizes, effectively preventing the product from sliding during the punching process, but also realize the automation of product transfer, greatly improving the stability and automation of punching and cutting, and further improving the quality and efficiency of production and processing.
