Description

Technical Field

[0001] This utility model relates to the technical field of hydraulic shearing machines, specifically to a hydraulic shearing machine for deck ladder support plates. Background Technology

[0002] This hydraulic shearing machine for deck ladder supports is used for precise cutting of deck ladder supports. Powered by hydraulic pressure, it applies shearing force to various metal sheets through a controlled blade gap, achieving the desired sheet dimensions. The equipment features a safety mechanism to prevent damage or injury during cutting, and a positioning block to prevent the sheet from bouncing during cutting, effectively ensuring operational safety and facilitating the efficient production of high-quality supports.

[0003] According to a public disclosure (Publication No.: CN219053047U), a hydraulic shearing machine for deck ladder support plates includes: a support platform, a placement plate fixedly connected to the upper part of the support platform, and positioning side plates connected to both sides of the placement plate. A cutting groove is provided between the U-shaped placement plates, and a cutting blade is positioned above the groove. A top plate is fixedly connected to one side of the upper end of the U-shaped placement plate, and a positioning strip located on one side of the top plate is also connected to the upper end of the U-shaped placement plate. A positioning plate is inserted between the top plate and the positioning strip. This utility model, by setting a protective mechanism on one side of the upper end of the support platform and sliding the U-shaped placement plate to the upper end of the support platform, allows the plate to move outward a certain distance during cutting, providing automatic buffering protection. Then, under the rebound action of multiple return springs, the U-shaped placement plate automatically returns to its original position. The structure is novel and highly practical.

[0004] However, the above applications have problems such as poor cutting effect and poor automatic material feeding effect. Therefore, a hydraulic shearing machine for deck ladder support plates is proposed. Utility Model Content

[0005] This utility model proposes a hydraulic shearing machine for deck ladder support plates, which solves the problems of poor cutting effect and poor automatic material feeding effect in related technologies.

[0006] According to one aspect, at least one embodiment of the present invention provides a hydraulic shearing machine for deck ladder support plates, comprising: a machine body, a support foot pad fixedly connected to the bottom of the machine body, a door panel slidably connected to the side of the machine body, a handle fixedly connected to the side of the door panel, a workbench fixedly connected to the inner side of the machine body, a gantry frame fixedly connected to the top of the workbench, and a feeding mechanism provided inside the machine body;

[0007] The feeding mechanism includes a motor, the bottom of which is fixedly connected to the inner wall of the machine body. A threaded rod is fixedly connected to the end of the motor output shaft. A threaded sleeve is threadedly connected to the circumferential surface of the threaded rod. A connecting rod is fixedly connected to the circumferential surface of the threaded sleeve. A displacement plate is fixedly connected to the end of the connecting rod away from the threaded sleeve. A rotating shaft is fixedly connected to the end of the threaded rod away from the motor. The end of the rotating shaft away from the threaded rod is rotatably connected to the inner wall of the machine body.

[0008] For example, in the hydraulic shearing machine for deck ladder support provided in at least one embodiment of the present invention, it is further provided that: a slide rail is provided on the side of the machine body, and the number of the slide rails is set to two, which are symmetrical to each other along the vertical central axis of the door panel. The slide rails on both sides simultaneously restrict the displacement of the door panel to prevent the door panel from tilting or getting stuck due to force on one side.

[0009] The side of the door panel is fixedly connected with two sliding strips, which are symmetrical about each other along the vertical central axis of the door panel. The cooperation between the two sliding strips and the slide rail is equivalent to providing double support for the door panel, distributing the weight of the door panel and the external force during operation, reducing the deformation or damage that may be caused by single-point force, and improving the reliability of the overall structure.

[0010] The number of support feet is set to several and arranged in a linear array at the bottom of the machine body. The width of the slide bar is equal to the width of the slide rail, which can evenly transfer the weight of the machine body to the ground, avoid single-point force causing the machine body to tilt or the ground to be deformed by local pressure, improve the anti-overturning ability, and ensure that the vibration during shearing will not cause the equipment to shift.

[0011] The side of the gantry is located on the displacement trajectory of the displacement plate, and the width of the connecting rod is equal to the width of the threaded sleeve, ensuring that the workpiece can be pushed to the cutting station to achieve the cutting function, and the driving force of the threaded sleeve can be evenly transmitted to the displacement plate.

[0012] According to another aspect, at least one embodiment of this utility model also provides a hydraulic shearing machine for deck ladder support plates, comprising: a hydraulic cutting mechanism, the hydraulic cutting mechanism including a half gear, the inner side of the half gear being fixedly connected to the circumferential surface of a rotating shaft, a slider being slidably connected to the inner wall of the machine body, a rack being fixedly connected to the side of the slider, the half gear and the rack meshing with each other, a spring being fixedly connected to the bottom of the rack, a U-shaped plate being fixedly connected to the side of the rack, a water tank being fixedly connected to the side of the gantry frame, an extrusion plate being slidably connected to the inner side of the water tank, a water pipe being fixedly connected to the top of the water tank, a hydraulic tank being fixedly connected to the top of the gantry frame, the end of the water pipe away from the water tank being fixedly connected to the top of the hydraulic tank, a hydraulic plate being slidably connected to the inner side of the hydraulic tank, a return spring being fixedly connected to the bottom of the hydraulic plate, the end of the return spring away from the hydraulic plate being fixedly connected to the inner wall of the hydraulic tank, a hydraulic rod being fixedly connected to the bottom of the hydraulic plate, and a cutter being fixedly connected to the bottom of the hydraulic rod.

[0013] For example, in at least one embodiment of the present invention, a hydraulic shearing machine for deck ladder support plates is provided, which further includes: a sliding groove is provided on the side of the water tank, and the number of sliding grooves is set to a plurality of them and arranged in a linear array on the side of the water tank; a sliding strip is fixedly connected to the side of the U-shaped plate, and the number of sliding strips is set to a plurality of them and arranged in a linear array on the side of the U-shaped plate. This can distribute the vertical load on the U-shaped plate to multiple contact points, avoid stress concentration at a single point causing rapid wear of the sliding groove or sliding strip, ensure the stability of hydraulic transmission and cutting accuracy, and reduce maintenance costs through modular design.

[0014] The cutter is fixedly connected to a slide bar on its side, and the gantry frame is provided with a slide rail on its side. There are two slide bars and two slide rails, which are symmetrical about each other along the vertical central axis of the cutter. This can suppress the rotation of the cutter around the vertical axis, limit the horizontal displacement of the cutter, and ensure that it moves only in the vertical direction, so as to avoid the cutter tilting due to the eccentricity of the hydraulic rod thrust.

[0015] The springs are arranged in pairs and are symmetrical about each other along the vertical central axis of the rack. When the half gear disengages from the rack, the two springs synchronously provide an upward restoring force to ensure that the rack rises vertically and avoids the rack tilting due to unilateral tension. The restoring springs are arranged in a circular array at the bottom of the hydraulic plate. The circular array of restoring springs synchronously applies restoring force from multiple directions to ensure that the hydraulic plate is evenly stressed during the rise and avoids the hydraulic plate tilting due to excessive unilateral tension.

[0016] The top of the spring is located on the displacement trajectory of the rack. The collinear design prevents the spring from bending or deforming due to uneven load or coil wear, thus extending the spring's lifespan. The side of the water pipe is located on the displacement trajectory of the extrusion plate. The extrusion plate moves vertically under the drive of the U-shaped plate, and its displacement trajectory is aligned with the side of the water pipe. This ensures that when the extrusion plate reaches its endpoint, it precisely extrudes the water pipe inlet, forcing the liquid in the water tank into the hydraulic tank through the water pipe. The top of the return spring is located on the displacement trajectory of the hydraulic plate, ensuring that all return springs apply force synchronously, pushing the hydraulic plate and the cutter to rise vertically along the gantry's slide rail, preventing the cutter from colliding with the slide rail due to misalignment during return.

[0017] The working principle and beneficial effects of this utility model are as follows:

[0018] 1. In this utility model, automatic feeding is achieved through the cooperation of components such as threaded rods, threaded sleeves and connecting rods inside the feeding mechanism, which reduces manual intervention and improves processing efficiency. The threaded rod transmission ensures accurate feeding distance and guarantees cutting precision. The symmetrical structure design avoids eccentric loads, making the transmission stable and extending the service life of the components. At the same time, the mechanism is linked with the hydraulic cutting mechanism to realize integrated continuous operation of feeding and cutting, which can meet the batch processing needs of deck ladder support plates.

[0019] 2. In this utility model, the U-shaped plate, hydraulic tank, and cutter components within the hydraulic cutting mechanism work together to convert motor power into vertical motion. This drives the U-shaped plate to compress the liquid in the water tank, transmitting pressure through water pipes to the hydraulic tank, which in turn pushes the hydraulic plate, hydraulic rod, and cutter to complete the cutting. The hydraulic transmission provides high driving force, making it suitable for cutting thick plates. Mechanical linkage automates cutting and resetting, improving efficiency. Symmetrical slide rails ensure vertical movement of the cutter, guaranteeing cutting accuracy. The multi-spring design distributes force evenly, reducing wear and extending the mechanism's lifespan. The compact fluid transmission structure of the water tank and hydraulic tank reduces leakage risk, meeting the high precision and reliability requirements of shipbuilding.

[0027] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without any creative effort.

[0028] To keep the drawings concise, only the parts relevant to the utility model are shown schematically in each drawing; these do not represent the actual structure of the product. Furthermore, for ease of understanding, in some drawings, only one of the components with the same structure or function is schematically shown, or only one is labeled. In this document, "a" not only means "only one," but can also mean "more than one," and "several" includes "two" and "more than two."

[0029] In this document, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0031] like Figures 1-5As shown, it illustrates a hydraulic shearing machine for deck ladder support plates according to an embodiment of the present invention, comprising: a machine body 1, a support foot pad 2 fixedly connected to the bottom of the machine body 1, a door panel 3 slidably connected to the side of the machine body 1, a handle 4 fixedly connected to the side of the door panel 3, a workbench 5 fixedly connected to the inner side of the machine body 1, a gantry frame 6 fixedly connected to the top of the workbench 5, and a feeding mechanism 7 provided inside the machine body 1.

[0032] The feeding mechanism 7 includes a motor 71, the bottom of which is fixedly connected to the inner wall of the machine body 1. The end of the output shaft of the motor 71 is fixedly connected to a threaded rod 72. A threaded sleeve 73 is threadedly connected to the circumferential surface of the threaded rod 72. A connecting rod 74 is fixedly connected to the circumferential surface of the threaded sleeve 73. A displacement plate 75 is fixedly connected to the end of the connecting rod 74 away from the threaded sleeve 73. A rotating shaft 76 is fixedly connected to the end of the threaded rod 72 away from the motor 71. The end of the rotating shaft 76 away from the threaded rod 72 is rotatably connected to the inner wall of the machine body 1.

[0033] In some examples, it also includes: the side of the body 1 is provided with a slide rail, the number of slide rails is set to two, and they are symmetrical to each other along the vertical central axis of the door panel 3. The two slide rails simultaneously restrict the displacement of the door panel 3 to prevent the door panel 3 from tilting or getting stuck due to force on one side.

[0034] The side of the door panel 3 is fixedly connected with two slide bars, which are symmetrical about each other along the vertical central axis of the door panel 3. The cooperation between the two slide bars and the slide rail is equivalent to providing double support for the door panel 3, distributing the weight of the door panel 3 and the external force during operation, reducing the deformation or damage that may be caused by single-point force, and improving the reliability of the overall structure.

[0035] The number of support feet 2 is set to several and arranged in a linear array at the bottom of the machine body 1. The width of the slide bar is equal to the width of the slide rail, which can evenly transfer the weight of the machine body 1 to the ground, avoid the machine body 1 tilting or the ground being deformed by local pressure due to single-point force, improve the anti-overturning ability, and ensure that the vibration during shearing will not cause the equipment to shift.

[0036] The side of the gantry 6 is located on the displacement trajectory of the displacement plate 75. The width of the connecting rod 74 is equal to the width of the threaded sleeve 73, ensuring that the workpiece can be pushed to the cutting station to achieve the cutting function. The driving force of the threaded sleeve 73 can be evenly transmitted to the displacement plate 75.

[0037] For example, such as Figures 1-5 As shown, the worker places the workpiece onto the displacement plate 75 through the door panel 3, starts the motor 71, and drives the threaded rod 72 to rotate. Utilizing the principle of threaded transmission, the threaded sleeve 73, which is threadedly connected to the threaded rod 72, produces linear motion. The threaded sleeve 73 is connected to the displacement plate 75 through the connecting rod 74, thereby driving the displacement plate 75 to move horizontally in a predetermined direction, pushing the deck ladder support plate to be processed to the cutting station below the gantry 6.

[0038] like Figures 1-5 As shown, this illustrates a hydraulic shearing machine for deck ladder support plates according to another embodiment of the present invention. Its technical solution is largely the same as that of Embodiment 1, so only the differences are described. It includes: a hydraulic cutting mechanism 8, comprising a half-gear 81, the inner side of which is fixedly connected to the circumferential surface of the rotating shaft 76; a slider 82 slidably connected to the inner wall of the machine body 1; a rack 83 fixedly connected to the side of the slider 82; the half-gear 81 and the rack 83 meshing with each other; a spring 84 fixedly connected to the bottom of the rack 83; a U-shaped plate 85 fixedly connected to the side of the rack 83; and a gantry frame 6 fixedly connected to the side of the rack 83. A water tank 86 is fixedly connected, and an extrusion plate 87 is slidably connected to the inner side of the water tank 86. A water pipe 88 is fixedly connected to the top of the water tank 86. A hydraulic tank 89 is fixedly connected to the top of the gantry frame 6. The end of the water pipe 88 away from the water tank 86 is fixedly connected to the top of the hydraulic tank 89. A hydraulic plate 810 is slidably connected to the inner side of the hydraulic tank 89. A return spring 811 is fixedly connected to the bottom of the hydraulic plate 810. The end of the return spring 811 away from the hydraulic plate 810 is fixedly connected to the inner wall of the hydraulic tank 89. A hydraulic rod 812 is fixedly connected to the bottom of the hydraulic plate 810. A cutter 813 is fixedly connected to the bottom of the hydraulic rod 812.

[0039] In some examples, the water tank 86 is provided with a groove on its side, and the number of grooves is set to a certain number and arranged in a linear array on the side of the water tank 86. The U-shaped plate 85 is fixedly connected with a slide bar, and the number of slide bars is set to a certain number and arranged in a linear array on the side of the U-shaped plate 85. This can distribute the vertical load on the U-shaped plate 85 to multiple contact points, avoid stress concentration at a single point causing rapid wear of the groove or slide bar, ensure the stability of hydraulic transmission and cutting accuracy, and reduce maintenance costs through modular design.

[0040] The cutter 813 is fixedly connected to a slide bar on its side, and the gantry 6 is provided with a slide rail on its side. There are two slide bars and two slide rails, which are symmetrical about each other along the vertical central axis of the cutter 813. This can suppress the rotation of the cutter 813 around the vertical axis, limit the horizontal displacement of the cutter 813, and ensure that it moves only in the vertical direction, so as to avoid the cutter 813 from tilting due to the eccentricity of the thrust of the hydraulic rod 812.

[0041] Two springs 84 are provided and are symmetrical to each other along the vertical central axis of the rack 83. When the half gear 81 disengages from the rack 83, the two springs 84 synchronously provide an upward restoring force to ensure that the rack 83 rises vertically and avoids the rack 83 tilting due to unilateral tension. Several return springs 811 are provided and are arranged in a circumferential array at the bottom of the hydraulic plate 810. The circumferential array of return springs 811 synchronously applies a restoring force from multiple directions to ensure that the hydraulic plate 810 is subjected to uniform force during the rise and avoids the hydraulic plate 810 tilting due to excessive unilateral tension.

[0042] The top of spring 84 is located on the displacement trajectory of rack 83. The collinear design can prevent spring 84 from bending and deforming or coil wear due to off-center load, thus extending the life of spring 84. The side of water pipe 88 is located on the displacement trajectory of extrusion plate 87. Extrusion plate 87 moves vertically under the drive of U-shaped plate 85. Its displacement trajectory is aligned with the side of water pipe 88, so that when extrusion plate 87 descends to the end point, it just squeezes the inlet of water pipe 88, and presses the liquid in water tank 86 into hydraulic tank 89 through water pipe 88. The top of return spring 811 is located on the displacement trajectory of hydraulic plate 810, which can ensure that all return springs 811 apply force synchronously, pushing hydraulic plate 810 and cutter 813 to rise vertically along the slide rail of gantry 6, avoiding collision between cutter 813 and slide rail due to return tilt.

[0043] For example, such as Figures 1-5 As shown, while the motor 71 drives the feeding mechanism 7, it also drives the rotating shaft 76 to rotate. The half gear 81 on its circumferential surface meshes with the rack 83, causing the rack 83 to descend vertically along the slider 82. The spring 84 at the bottom of the rack 83 is compressed to store elastic potential energy. The U-shaped plate 85 on the side pushes the extrusion plate 87 in the water tank 86 to move vertically, forcing liquid into the hydraulic tank 89 through the water pipe 88. Under the action of liquid pressure, the hydraulic plate 810 overcomes the return spring 811 and descends, driving the cutter 813 to complete the cutting through the hydraulic rod 812. After the half gear 81 disengages, the spring 84 and the return spring 811 respectively drive the rack 83 and the hydraulic plate 810 to return to their original positions, and the cutter 813 rises back.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
