Description

Technical Field

[0001] This utility model relates to the field of steel cutting technology, specifically to a steel cutting device. Background Technology

[0002] Steel is a material with specific shapes, dimensions, and properties, made from steel ingots, billets, or other steel products through pressure processing. Steel is an important category of metal plastic processing products. Of the total steel production, with the exception of a small portion produced through casting and powder metallurgy, the vast majority is processed into steel products through plastic processing. Steel has a wide range of applications and varieties. Based on their cross-sectional shape, steel products are generally classified into four main categories: profiles, plates, pipes, and metal products.

[0003] Currently, during the steel cutting process, it is impossible to fix the steel according to its different sizes. As a result, the steel plate is prone to shaking and shifting during the cutting process, affecting the cutting accuracy. Consequently, the cut surface is often not flat enough, with many weld beads, burrs, and other rough edges, which is not conducive to subsequent processing. Utility Model Content

[0004] The purpose of this invention is to provide a steel cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a steel cutting device, comprising:

[0006] A cutting table, wherein a cutting slit is provided in the middle of the upper side of the cutting table, a drive frame is fixed on the cutting table, a movable cutting component is provided inside the drive frame, pressing components are provided on both the front and rear sides of the drive frame, and limiting components are provided on both the front and rear parts of the lower side of the cutting table.

[0007] The feeding rack and the discharging rack are symmetrically installed on the front and rear sides of the cutting table. Both the feeding rack and the discharging rack have grooves, and multiple rollers are movably nested in the grooves at equal intervals.

[0008] Preferably, the bottom two ends of the drive frame are connected to the upper left and right sides of the cutting table, respectively, and the drive frame has a transmission groove inside;

[0009] The mobile cutting assembly includes a drive motor, a lead screw, and a moving cover. The lead screw is rotatably mounted in a transmission groove. The drive motor is mounted on the left side wall of the drive frame. The output end of the drive motor is connected to the lead screw. A nut seat is sleeved on the lead screw. The nut seat is slidably connected to the transmission groove. A connecting seat is fixed at the bottom of the nut seat. The connecting seat is connected to the moving cover. A saw blade and a cutting motor are nested inside the moving cover. The cutting motor is connected to the saw blade via a pulley drive.

[0010] The drive motor rotates the lead screw, which in turn moves the nut seat on the lead screw, thereby moving the connecting seat. The moving connecting seat moves the moving cover, which in turn moves the saw blade to perform cutting.

[0011] Preferably, the bottom end of the saw blade is nested within the cutting kerf, thereby enabling effective cutting of the steel plate.

[0012] Preferably, the pressing assembly includes a first fixed plate seat, which is connected to the side wall of the drive frame. A first cylinder is fixed on the first fixed plate seat, and the output end of the first cylinder passes through the first fixed plate seat and is connected to a lower pressing frame. Two pressure rollers are connected to the bottom of the lower pressing frame. The first cylinder pushes the lower pressing frame to move downward, and the downward movement of the lower pressing frame drives the pressure rollers to move downward to squeeze the steel plate, thereby preventing the steel plate from moving or warping during cutting.

[0013] Preferably, the pressure roller is positioned directly above the bottom roller, and the diameter of the pressure roller is the same as that of the roller. The pressure roller and the roller cooperate to squeeze the steel plate between them, preventing the steel plate from warping at the cut and affecting the cutting effect.

[0014] Preferably, the limiting component includes a second fixed plate base, which is fixed to the bottom of the cutting table. A second cylinder is installed on the second fixed plate base, and the output end of the second cylinder is connected to a movable plate base. Multiple vertical limiting rods are fixed at equal intervals on the upper left and right sides of the movable plate base. The multiple vertical limiting rods pass through corresponding grooves. The second cylinder drives the movable plate base to move, and the movement of the movable plate base causes the vertical limiting rods to move and contact the edge of the steel plate, thereby limiting the steel plate and preventing it from shifting.

[0015] Preferably, the vertical limiting rod and the roller are spaced apart so that the roller and the vertical limiting rod do not affect each other.

[0016] Preferably, the top of the roller is flush with the upper surface of the cutting table.

[0017] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0018] By incorporating a moving cutting assembly, two pressing assemblies, and two limiting assemblies, the second cylinders on the two limiting assemblies activate during steel plate cutting, causing the vertical limiting rod to move and contact the edge of the steel plate, thus limiting the steel plate and preventing it from shifting. Simultaneously, the first cylinders on the two pressing assemblies activate, causing the pressure rollers to move downwards and squeeze the steel plate, preventing it from shifting or warping during cutting. Then, the moving cutting assembly performs the cutting. The two pressing assemblies and the two limiting assemblies work together to effectively maintain the stability of the steel plate during cutting, preventing the steel plate from shifting, tilting, or warping at the cut point, thereby improving processing accuracy.

[0028] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0029] This utility model provides, for example Figures 1 to 6 The steel cutting device shown includes:

[0030] A cutting table 1 has a cutting slit 2 in the middle of its upper side. A drive frame 3 is fixed on the cutting table 1. A movable cutting component is installed inside the drive frame 3. Pressing components are installed on both the front and rear sides of the drive frame 3. Limiting components are installed on both the front and rear sides of the lower side of the cutting table 1.

[0031] Feed rack 4 and discharge rack 5 are symmetrically installed on the front and rear sides of the cutting table 1. Both feed rack 4 and discharge rack 5 have grooves 6, and multiple rollers 7 are movably nested in the grooves 6 at equal intervals.

[0032] The bottom ends of the drive frame 3 are connected to the upper left and right sides of the cutting table 1, respectively, and the drive frame 3 has a transmission groove 8 inside.

[0033] The mobile cutting assembly includes a drive motor 9, a lead screw 10, and a moving cover 11. The lead screw 10 is rotatably mounted in the transmission groove 8. The drive motor 9 is mounted on the left side wall of the drive frame 3. The output end of the drive motor 9 is connected to the lead screw 10. A nut seat 12 is sleeved on the lead screw 10. The nut seat 12 is slidably connected to the transmission groove 8. A connecting seat 13 is fixed at the bottom of the nut seat 12. The connecting seat 13 is connected to the moving cover 11. A saw blade 14 and a cutting motor are nested inside the moving cover 11. The cutting motor is connected to the saw blade 14 through a belt pulley drive.

[0034] The drive motor 9 drives the lead screw 10 to rotate. The rotation of the lead screw 10 causes the nut seat 12 to move on the lead screw 10, thereby driving the connecting seat 13 to move. The movement of the connecting seat 13 drives the moving cover 11 to move, thereby driving the saw blade 14 to move for cutting.

[0035] The bottom end of the saw blade 14 is nested inside the cutting slit 2, thereby enabling effective cutting of the steel plate.

[0036] The pressing assembly includes a first fixed plate seat 16, which is connected to the side wall of the drive frame 3. A first cylinder 17 is fixed on the first fixed plate seat 16. The output end of the first cylinder 17 passes through the first fixed plate seat 16 and is connected to a lower pressing frame 18. Two pressure rollers 19 are connected to the bottom of the lower pressing frame 18. The first cylinder 17 pushes the lower pressing frame 18 to move downward. The downward movement of the lower pressing frame 18 causes the pressure rollers 19 to move downward to squeeze the steel plate, thereby preventing the steel plate from moving or warping during cutting.

[0037] The pressure roller 19 is positioned directly above the corresponding bottom roller 7. The diameter of the pressure roller 19 is the same as that of the roller 7. The pressure roller 19 cooperates with the roller 7 to squeeze the steel plate between them, preventing the steel plate from warping at the cut and affecting the cutting effect.

[0038] The limiting assembly includes a second fixed plate seat 20, which is fixed to the bottom of the cutting table 1. A second cylinder 21 is installed on the second fixed plate seat 20. The output end of the second cylinder 21 is connected to a movable plate seat 22. Multiple vertical limiting rods 15 are fixed at equal intervals on the upper left and right sides of the movable plate seat 22. The multiple vertical limiting rods 15 pass through the corresponding grooves 6. The second cylinder 21 drives the movable plate seat 22 to move. The movement of the movable plate seat 22 causes the vertical limiting rods 15 to move and contact the edge of the steel plate, thereby limiting the steel plate and preventing it from shifting.

[0039] The vertical limiting rod 15 is spaced apart from the roller 7 so that the roller 7 and the vertical limiting rod 15 do not affect each other.

[0040] The top of the roller 7 is flush with the upper surface of the cutting table 1.

[0041] In this invention, a steel plate extends from the feed rack 4, aligning the area to be cut on the steel plate with the cutting seam 2 on the cutting table 1. During cutting, the second cylinders 21 on the two limiting components operate, pushing the movable plate seat 22 to move. The moving plate seat 22 causes the vertical limiting rod 15 to move and contact the edge of the steel plate, limiting the steel plate and preventing it from shifting. Simultaneously, the first cylinders 17 on the two pressing components operate, pushing the lower pressing frame 18 downwards. The downward movement of the lower pressing frame 18 causes the pressure roller 19 to move downwards, pressing the steel plate... The plate is pressed to prevent it from shifting or warping during cutting. Then, the drive motor 9 on the moving cutting assembly drives the lead screw 10 to rotate. The rotation of the lead screw 10 causes the nut seat 12 to move on the lead screw 10, thereby driving the connecting seat 13 to move. The movement of the connecting seat 13 drives the moving cover 11 to move, which in turn drives the saw blade 14 to move for cutting. The two pressing components and the two limiting components work together to effectively maintain the stability of the steel plate during cutting, preventing the steel plate from shifting or warping at the cut, thus improving processing accuracy.

[0042] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
