Description

Technical Field

[0001] This utility model relates to the field of metal processing technology, and in particular to a high-speed metal shearing machine. Background Technology

[0002] Shearing machines, as specialized metal cutting equipment, play a crucial role. They are not only called shearing machines, but also sometimes figuratively referred to as plate shears or plate cutting machines; these names clearly reveal their core function—precise cutting and trimming of metal sheets. The working principle of a shearing machine is quite straightforward and efficient: the operator places the metal sheet to be processed stably on the machine's worktable, and then, through a built-in transmission system, drives the up-and-down moving scissor-like blades to precisely cut the sheet. This process not only ensures the accuracy of the cut but also greatly improves the efficiency of metal sheet processing, providing indispensable technical support for manufacturing, construction, and many other industries that require metal sheet processing, helping enterprises achieve efficient and precise metal processing production.

[0003] However, despite the significant advantages of shearing machines in metal sheet processing, most shearing machines on the market today require operators to rely on experience to manually control the sheet material's feeding speed when production demands change and adjustments to the shearing rate are needed, in order to achieve the desired shearing effect. Therefore, this method not only fails to guarantee the accuracy of the shearing rate but is also inefficient and cannot achieve rapid adjustments. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a fast metal shearing machine that can quickly adjust the shearing amount and improve the accuracy of the shearing amount.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A high-speed metal shearing machine includes a frame with multiple conveying rollers rotatably mounted on it. The tops of the multiple conveying rollers are at the same horizontal plane. The frame is equipped with multiple driving components for driving the conveying rollers to rotate. A clamping and positioning assembly is provided at the end of the frame in the direction of metal sheet travel. A fixed frame is provided above the clamping and positioning assembly. A metal cutting assembly is provided on the top beam of the fixed frame. A measuring assembly is provided on one side of the fixed frame.

[0007] The measuring component includes a horizontal telescopic member, the extension direction of the movable part of the telescopic member is the same as the travel direction of the metal sheet, a baffle is provided on the movable part of the telescopic member, a contact switch is provided on the baffle facing the fixed frame, and a travel control device for controlling the travel of the telescopic member is provided on the frame.

[0008] When the metal plate comes into contact with the contact switch, the contact switch controls the clamping and positioning component to clamp the metal plate through the control unit, and then controls the metal cutting component to cut.

[0009] Preferably, the clamping and positioning assembly includes two sets of clamping cylinders arranged in opposite directions, each clamping cylinder being provided with an L-shaped clamping plate, and a gap being provided between the two sets of clamping plates for the metal cutting assembly to pass through.

[0010] Preferably, the frame is provided with a fixed support plate below the clamping and positioning assembly, the upper surface of the fixed support plate is in contact with the lower surface of the clamping plate, and the fixed support plate is used to support the clamping plate.

[0011] Preferably, the metal cutting assembly includes a lifting hydraulic cylinder connected to a fixed frame, and a shearing blade is provided on the bottom movable part of the lifting hydraulic cylinder.

[0012] Preferably, there are two lifting cylinders located on both sides of the shearing blade.

[0013] Preferably, the driving component is a motor, and the telescopic component is a hydraulic rod.

[0014] This utility model has the following beneficial effects:

[0015] I. Rapid Adjustment of Shearing Amount: By setting up horizontal and vertical telescopic components (hydraulic rods), the extension direction of their moving parts is the same as the direction of metal sheet travel. This allows for flexible adjustment of the baffle position according to actual needs, thereby quickly changing the reference point for the shearing amount. The stroke control device ensures precise control of the telescopic component's stroke, guaranteeing that each adjustment achieves the expected shearing amount. When the metal sheet contacts the contact switch, the contact switch responds rapidly through the control unit, triggering subsequent clamping and cutting actions. The entire process is highly automated and has a fast response speed.

[0016] II. Improving the Precision of Shearing Amount: The clamping and positioning assembly includes two sets of opposing clamping cylinders, each with an L-shaped clamping plate. A gap is provided between the two clamping plates for the metal cutting assembly to pass through. This design ensures that the metal sheet is precisely clamped before cutting, avoiding shearing errors caused by sheet movement. The fixed support plate further enhances the stability of the clamping, ensuring the positional accuracy of the sheet during the cutting process. The metal cutting assembly includes two lifting cylinders connected to the fixed frame, with a shearing blade mounted on the movable part at the bottom of each cylinder. The two lifting cylinders, located on either side of the shearing blade, ensure the stability and uniformity of the shearing blade during the cutting process, improving the precision of the shearing amount.

[0017] In summary, the combination of the telescopic components and the stroke control device enables rapid and flexible adjustment of the shearing amount, meeting diverse production needs. Precise clamping and positioning components and stable cutting components ensure the positional accuracy and cutting quality of the metal sheet during the cutting process, improving the precision of the shearing amount. The coordination of the contact switch and control unit enables automated control of the cutting process, reducing manual intervention and improving production efficiency. The design of components such as the clamping cylinder, fixed support plate, and lifting hydraulic cylinder ensures the structural stability and reliability of the entire shearing machine, extending the equipment's service life.

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] First embodiment

[0024] like Figures 1 to 2As shown, a high-speed metal shearing machine includes a frame 1, on which multiple conveyor rollers 2 are rotatably mounted, with their tops on the same horizontal plane. Multiple drive units 3 are mounted on the frame 1 to drive the conveyor rollers 2 to rotate. A clamping and positioning assembly is located at the end of the frame 1 in the direction of metal sheet travel. A fixed frame 4 is located above the clamping and positioning assembly, and a metal cutting assembly is mounted on the top beam of the fixed frame 4. A measuring assembly is located on one side of the fixed frame 4. The measuring assembly includes a horizontally extending telescopic member 501, the extension direction of which is the same as the direction of metal sheet travel. A baffle 502 is located on the extending part of the telescopic member 501, and a contact switch 503 is located on the baffle 502 facing the fixed frame 4. A travel control device 504 is mounted on the frame 1 to control the travel of the telescopic member 501. When the metal sheet comes into contact with the contact switch 503, the contact switch 503, through the control unit, controls the clamping and positioning assembly to clamp the metal sheet, and then controls the metal cutting assembly to cut it.

[0025] First, the metal sheet is loaded and conveyed. Specifically, the metal sheet to be cut is placed stably on the conveyor rollers 2 on the frame 1. Since the tops of multiple conveyor rollers 2 are all on the same horizontal plane, the stability of the sheet is ensured during the conveying process. Then, the drive unit 3 (e.g., a motor) drives the conveyor rollers 2 to rotate, thereby moving the metal sheet continuously along the direction of travel until the sheet accurately reaches the predetermined operating position. Second, the shearing amount is measured and positioned. During the measurement component's operation, the movable part of the telescopic component 501 (e.g., a hydraulic rod) extends to the designated position according to the preset shearing amount, and the baffle 502 on it also moves accordingly. The metal sheet continues to move until its front end makes close contact with the baffle 502 and triggers the contact switch 503. During the clamping and positioning stage, the contact switch 503 sends a signal to the clamping and positioning component through the control unit. At this time, two sets of opposing clamping cylinders 601 are quickly activated, causing the L-shaped clamping plate 602 to quickly and firmly clamp the metal sheet. Furthermore, the fixed support plate 603 supports the lower surface of the clamping plate 602, effectively preventing the sheet metal from shifting due to force during cutting. Next, the metal sheet cutting operation is performed. After successful clamping and positioning, the control unit activates the metal cutting assembly. At this time, the two sets of lifting cylinders 701 descend synchronously, driving the shearing blade 702 to press vertically downwards, precisely cutting the metal sheet. The design of the lifting cylinders 701 on both sides of the shearing blade 702 ensures uniform force on the blade edge during cutting, effectively avoiding sheet metal deformation or uneven cut surfaces. After cutting, the lifting cylinders 701 rise, the clamping cylinders 601 release, and the uncut metal sheet can continue to be conveyed, while the cut metal sheet falls naturally due to the lack of support and is removed. Finally, by repeating the above steps, continuous and automated metal sheet shearing production can be achieved, significantly improving production efficiency and product quality.

[0026] like Figures 1 to 2 As shown, the clamping and positioning assembly includes two sets of clamping cylinders 601 arranged facing each other. Each clamping cylinder 601 is equipped with an L-shaped clamping plate 602, and a gap is provided between the two sets of clamping plates 602 for the metal cutting assembly to pass through. When the cylinders are activated, the two sets of clamping plates 602 quickly close, forming a double clamping action on the metal sheet both laterally and longitudinally through the L-shaped structure, ensuring the sheet's stable position during the cutting process.

[0027] like Figures 1 to 2 As shown, a fixed support plate 603 is provided below the clamping and positioning assembly in the frame 1. The upper surface of the fixed support plate 603 is in contact with the lower surface of the clamping plate 602, and the fixed support plate 603 is used to support the clamping plate 602. The fixed support plate 603 not only supports the clamping plate 602 and disperses the pressure of the plate on the cylinder, but also enhances the stability of the clamping plate 602 through friction, preventing the plate from shifting or deforming due to force during cutting.

[0028] like Figures 1 to 2 As shown, the metal cutting assembly includes two lifting hydraulic cylinders 701, symmetrically distributed on both sides of the shearing blade 702. The movable part at the bottom of the hydraulic cylinder is connected to the shearing blade 702, and the cutting action is achieved through synchronous lifting. The dual hydraulic cylinder design ensures that the shearing blade 702 is subjected to uniform force during cutting, avoiding blade skewing or sheet metal deformation caused by force on one side, while also improving the flatness of the cut surface.

[0029] The drive unit 3 uses a motor to drive the conveyor roller 2 to rotate via belt or gear transmission, thus moving the metal sheet along the travel direction. The telescopic component 501 uses a hydraulic rod, the movable part of which can extend to a preset position along the travel direction of the sheet. The baffle 502 on the hydraulic rod is linked to the contact switch 503. When the front end of the sheet triggers the contact switch 503, the system immediately starts the clamping and cutting process.

[0030] Second embodiment

[0031] The movable part of the telescopic component 501 is marked with a scale. The movable part of the telescopic component 501 (such as a hydraulic rod) is mounted on the frame 1 and achieves linear extension and retraction along the direction of sheet metal travel via hydraulic drive. Its stroke range covers the shearing requirements of the metal sheet. The surface of the movable part is marked with a millimeter-level scale, the scale range of which corresponds perfectly to the stroke of the telescopic component 501. For example, when the movable part extends to the "100mm" mark, the baffle 502 simultaneously moves to a position 100mm from its initial position, directly corresponding to the shearing amount of the metal sheet.

[0032] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
