Description

Technical Field

[0001] This utility model relates to the field of flying shear technology, specifically to a high-performance flying shear. Background Technology

[0002] High-performance flying shears are devices developed in industries such as metal processing to meet the demand for efficient and high-precision shearing of moving metal materials. With the development of steel production technology, efficient production processes such as continuous casting and rolling are widely used, requiring rapid and accurate shearing of moving high-temperature steel billets and strips on the production line to achieve process requirements such as fixed-length cutting and coiling.

[0003] When the cutting tool begins its shearing action, the moving blade receives downward force through the drive mechanism, while the fixed blade remains stationary on the worktable. During shearing, the moving blade moves downward at a certain speed and force, cooperating with the fixed blade to compress and cut the sheet material.

[0004] Existing technology relies on the weight of the board itself to maintain horizontality during shearing. When dealing with boards with uneven surfaces, the shearing accuracy and performance are greatly reduced. Utility Model Content

[0005] This invention addresses the technical problem in existing shearing techniques where the shearing accuracy and performance are significantly reduced when dealing with uneven surfaces due to reliance on the weight of the sheet material for horizontal positioning. Therefore, this invention provides a high-performance flying shear.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-performance flying shear, comprising: a workbench, frames connected to both sides of the workbench, a support plate connected between the two frames, a shearing mechanism connected to the workbench, a pressing mechanism provided in front of the shearing mechanism along the board conveying direction on the workbench, and a board drop opening opened on the workbench behind the shearing mechanism. The pressing mechanism includes a hydraulic cylinder, the fixed end of which is connected to the support plate, the telescopic end of which passes through the workbench and is connected to a pressure plate, a roller frame connected to the lower part of the pressure plate, and a rubber roller shaft rotatably connected inside the roller frame.

[0007] Preferably, a slide rod is connected to the upper surface of the roller frame, the slide rod is slidably connected to the pressure plate, a limit plate is connected to the upper end of the slide rod, and a spring is sleeved on the slide rod. The two ends of the spring are in contact with the lower surface of the pressure plate and the upper surface of the roller frame, respectively, and the spring is in a compressed state.

[0008] Preferably, the shearing mechanism includes a motor connected to a support plate. The motor output shaft is connected to a disc shaft via a bevel gear set. The disc shaft is connected to the support plate via a bearing seat. A disc is connected to the end of the disc shaft. A lever is connected to the outer surface of the disc. The lower end of a connecting rod is rotatably connected to the lever. The upper end of the connecting rod is rotatably connected to a slide. The slide is slidably connected to a slide rail. The slide rail is connected to the worktable via a fixed blade. The slide is connected to a moving blade via bolts. The moving blade can cooperate with the fixed blade to shear the plate.

[0009] Preferably, an inclined plate is connected to the support plate at the lower part of the drop plate opening.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] 1. The pressure plate is lowered by the hydraulic cylinder. The pressure plate drives multiple rubber rollers to flatten the sheet material to be sheared. When the rear push plate mechanism pushes the sheet material forward, the rubber rollers rotate, changing the sliding friction on the upper part of the sheet material into rolling friction. This keeps the sheet material straight while greatly reducing the forward resistance of the sheet material and improving the shearing accuracy and performance.

[0012] 2. Under the action of the spring, the rubber roller can cooperate with the lower plate to conform to its shape, and can also stably flatten the plate when facing plates with varying thicknesses. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings.

[0021] The following is in conjunction with the appendix Figure 1-4 This embodiment describes a high-performance flying shear, comprising: a workbench 1, frames 2 connected to both sides of the workbench 1, a support plate 3 connected between the two frames 2, a shearing mechanism 4 connected to the workbench 1, a pressing mechanism 5 provided in front of the shearing mechanism 4 along the material conveying direction on the workbench 1, and a dropping port 6 opened on the workbench 1 behind the shearing mechanism 4. The pressing mechanism 5 includes a hydraulic cylinder 51, the fixed end of the hydraulic cylinder 51 is connected to the support plate 3, the telescopic end of the hydraulic cylinder 51 passes through the workbench 1 and is connected to a pressure plate 52, a roller frame 53 is connected to the lower part of the pressure plate 52, and a rubber roller 54 shaft is rotatably connected inside the roller frame 53.

[0022] In use, the sheet metal is placed under the shearing mechanism 4 on the workbench 1. The pressure plate 52 is lowered by the hydraulic cylinder 51. The pressure plate 52 drives multiple rubber rollers 54 to flatten the sheet metal to be sheared. When the rear pusher mechanism pushes the sheet metal forward, the rubber rollers 54 rotate, changing the sliding friction on the upper part of the sheet metal into rolling friction. This keeps the sheet metal straight while being sheared by the shearing mechanism 4, greatly reducing the forward resistance of the sheet metal and improving the shearing accuracy and performance.

[0023] A slide rod 55 is connected to the upper surface of the roller frame 53. The slide rod 55 is slidably connected inside the pressure plate 52.

The two ends of the spring 57 are in contact with the lower surface of the pressure plate 52 and the upper surface of the roller frame 53, respectively. The spring 57 is in a compressed state.

[0024] When dealing with sheet materials with varying thicknesses, the roller frame 53 moves downward under the action of the spring 57. The roller frame 53 drives the rubber roller to conform to the shape of the lower sheet material, thus stably flattening the sheet material with thickness differences.

[0025] The shearing mechanism 4 includes a motor 41, which is connected to the support plate 3. The output shaft of the motor 41 is connected to the disc shaft 43 through a bevel gear set 42.

The slide 48 is slidably connected to the slide rail 49. The slide rail 49 is connected to the worktable 1 through a fixed blade 410. The slide 48 is connected to the moving blade 411 by bolts. The moving blade 411 can cooperate with the fixed blade 410 to shear the plate.

[0026] Motor 41 drives disc shaft 43 to rotate via bevel gear set 42. Disc shaft 43 drives two discs 45 to rotate. Discs 45 drive the lower end of connecting rod 47 to make circular motion via lever 46. The upper end of connecting rod 47 drives slide 48 to reciprocate along slide rail 49. Slide 48 drives moving blade 411 to reciprocate and cooperate with fixed blade 410 to achieve shearing.

[0027] An inclined plate 7 is connected to the support plate 3 at the lower part of the drop plate opening 6.

[0028] The cut boards fall onto inclined plate 7 and are guided out by inclined plate 7 to avoid direct drop and damage to the boards.
