Description

Technical Field

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

[0002] In the existing technology, ordinary cutting machines are generally used to cut steel. The specific operation is to place the steel to be cut on the operating table, then use a clamp to fix the steel, and then move the cutting equipment to cut the surface of the steel. The cutting machine automatically cuts the steel to obtain the required length of steel.

[0003] During the cutting process, the cutting equipment vibrates due to the contact between the cutting blade and the steel, causing slight deviations in the cutting path. This results in the cut steel not meeting the required length or width. Furthermore, the movement distance of existing cutting equipment is uncontrolled, often causing the cut length to exceed the specified distance or be insufficient. This often necessitates secondary processing of the steel, which requires recalibration and increases workload. Utility Model Content

[0023] Example

[0024] This utility model provides a steel segmentation cutting device, such as... Figures 1-5As shown, the main solution addresses the problem that existing cutting tools have a limited range of movement when cutting steel profiles. This results in insufficient cutting range for large sections, preventing one-time forming and often requiring secondary adjustments after cutting, which is time-consuming and labor-intensive, and compromises the cutting accuracy of the finished parts. The cutting device mainly consists of a cutting frame 1, which is constructed from steel profiles and is rectangular in shape. A cutting window 11 is located in the center of the cutting structure to prevent the cutting tool 5 from colliding with the cutting frame 1 during cutting, thus improving the safety of the structure during operation.

[0025] A retainer 3 is mounted on the side wall of the cutting frame 1. The retainer 3 is used to fix the mounting shaft 4 and the drive motor 2. The mounting shaft 4 is mounted on the side wall of the retainer 3 via bearings. The mounting shaft 4 is a hollow tubular structure. A cutting tool 5 is sleeved on the outer side wall of the mounting shaft 4. The cutting tool 5 is disc-shaped. The drive motor 2 is bolted to the other side of the retainer 3. The drive motor 2 is a high-power three-phase motor. The drive motor 2 and the mounting shaft 4 are connected by a coupling to ensure that the power output of the drive motor 2 is efficiently transmitted to the cutting tool 5, thereby cutting the profile to be cut. The side wall of the cutting frame 1 is provided with a first adjusting mechanism for driving the retainer 3 to move along the extension direction of the cutting frame 1. This structure ensures that the cutting tool 5 moves along the extension direction of the steel to be cut, thereby continuously cutting the steel. The cutting frame 1 is equipped with a support structure for supporting the free end of the mounting shaft 4. This support structure provides rigid support to the mounting shaft 4 as it moves along the x-axis or y-axis, preventing axial displacement or vibration during high-speed rotation and improving the stability of the cutting tool 5 during rotation. The support structure also includes a vibration damping structure to prevent tool vibration. This damping structure prevents the cutting tool 5 from deviating from its rotational surface when it comes into contact with the steel being cut during rotation, thus improving the cutting effect of this structure.

[0026] In some technical solutions of this utility model, the first adjustment mechanism includes a mounting platform 16 and two paired guide bars 15, which are rectangular or wedge-shaped. The mounting platform 16 is mounted on the side wall of the cutting machine frame 1, and two guide grooves are formed on the side wall of the mounting platform 16 along the extension direction of the cutting machine frame 1. The two guide bars 15 are respectively installed in the two guide grooves. A connecting frame 14 connected to the guide bars 15 is installed on the side wall of the retainer 3. The connecting frame 14, the retainer 3, and the guide bars 15 are all fixedly connected by bolts. A driving mechanism for driving the guide bars 15 to move is provided in the guide groove.

[0027] In some technical solutions of this utility model, the driving mechanism includes a mounting groove formed on the side wall of the guide bar 15, a transmission wheel rotatably mounted in the mounting groove via a shaft, the transmission wheel being a gear 18 structure, limiting grooves provided on the two opposite side walls of the guide groove, a portion of the transmission wheel being embedded in the limiting groove, a rack 17 installed in any one of the limiting grooves, the transmission wheel meshing with the rack 17, and a servo motor connected to the transmission wheel installed in the mounting groove.

[0028] In some technical solutions of this utility model, the mounting platform 16 is slidably disposed on the side wall of the cutting frame 1, and two push rods 13 are installed at the bottom of the cutting frame 1, with the telescopic ends of the push rods 13 connected to the mounting platform 16. The push rods 13 are either electric or hydraulic. The servo motor in the first adjustment mechanism drives the transmission wheel to mesh with the rack 17, causing the guide bar 15 to move along the extension direction of the cutting frame 1, so that the retainer 3 and the cutting tool 5 are precisely adjusted to the initial cutting position. If vertical adjustment is required, the push rods 13 at the bottom of the cutting frame 1 push the mounting platform 16 to slide relative to the cutting frame 1, and the guide rods 12 in the limiting holes ensure the stability of movement.

[0029] In some technical solutions of this utility model, a limiting hole adapted to the guide rod 12 is provided on the side wall of the mounting platform 16, and the guide rod 12 passes through the limiting hole. The guide rod 12 has an optical axis structure.

[0030] In some technical solutions of this utility model, the retainer 3 is perpendicular to the cutting machine frame 1. This ensures that the cutting tool 5 cuts the steel profile to be cut in a vertical direction, thus ensuring the cutting effect of the steel profile.

[0031] In some technical solutions of this utility model, the support structure includes a support frame 10 welded to the cutting machine frame 1. A stabilizing frame 6, coaxial with the mounting shaft 4, is mounted on the top of the support frame 10. The stabilizing frame 6 is rotatably mounted on the top of the support frame 10 via bearings and has a smooth shaft structure. A mounting hole adapted to the stabilizing frame 6 is provided on the side wall of the mounting shaft 4, and a portion of the stabilizing frame 6 passes through the mounting hole. The stabilizing frame 6 is inserted into the mounting hole of the mounting shaft 4, rigidly supporting the mounting shaft 4 and preventing axial displacement or vibration under high-speed rotation.

[0032] In some technical solutions of this utility model, the anti-vibration structure includes two paired mounting rings 8, one of which is mounted on the mounting shaft 4, and the other is mounted on the stabilizing frame 6. Anti-vibration frames 7 are rotatably mounted on the sidewalls of the mounting rings 8 opposite to the cutting tool. A torsion spring 9 is installed between the anti-vibration frame 7 and the mounting ring 8, and the free end of the anti-vibration frame 7 abuts against the end face of the tool. The anti-vibration frame 7 is a telescopic rod. The two mounting rings 8 are respectively fixed on the mounting shaft 4 and the stabilizing frame 6. The contact force of the telescopic rod of the anti-vibration frame 7 is adjusted by the torsion spring 9 to absorb the vibration when the cutting tool 5 contacts the steel, preventing the tool disc from deviating from the rotation center. Furthermore, the dynamic damping of the anti-vibration frame 7 counteracts the vibration, ensuring that the rotation center of the tool is always aligned with the cutting line, thus improving the cutting accuracy of the profile to be cut. The contact surface between the anti-vibration frame 7 and the cutting tool 5 has a rounded transition, or a sphere is embedded at the end of the anti-vibration frame 7, which can rotate relative to the anti-vibration frame 7.

[0033] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
