Description

Technical Field

[0001] This utility model belongs to the field of cutting equipment technology, and in particular relates to a cutting equipment with an H-beam fixing mechanism. Background Technology

[0002] A pipe cutting machine is a specialized piece of equipment used for cutting and processing pipes. It is widely used in industries such as metallurgy, machinery manufacturing, construction, chemical engineering, and petroleum. It can perform straight-line cutting, beveling, and slant cutting on various types of materials, including steel pipes, stainless steel pipes, H-beams, and angle steel. Its working principle involves a motor driving the cutting tool (such as an abrasive wheel, saw blade, plasma cutting torch, or laser head) to rotate at high speed or generate a high-energy beam. This, combined with the feeding system, applies cutting force to the pipe, achieving material separation.

[0003] Because of their large weight, considerable thickness, and irregular shape (not the conventional round or square), H-beams are difficult to cut using traditional pipe cutting machines designed primarily for round or square cross-section steel. Their fixing mechanisms are ill-suited to the unique cross-sectional shape of H-beams. Due to their heavy weight, fixing H-beams using single-point or partial contact means that vibrations and impacts during the cutting process can easily cause workpiece displacement, resulting in cutting quality issues such as tilted cut surfaces. Utility Model Content

[0004] Based on the above background, the purpose of this utility model is to provide a cutting device with an H-beam fixing mechanism.

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

[0006] A cutting device with an H-beam fixing mechanism includes a frame, on which a first mounting plate is provided, and a second mounting plate is rotatably provided on the side of the first mounting plate;

[0007] Both the first mounting plate and the second mounting plate have through slots, and the through slots are circular.

[0008] The second mounting plate is equipped with a cutting assembly;

[0009] The first mounting plate is provided with a clamping assembly; the clamping assembly includes an upper clamping block and a lower clamping block;

[0010] Both the upper clamping block and the lower clamping block are V-shaped structures and are slidably mounted on the first mounting plate.

[0011] The upper clamping block and the lower clamping block are located on the upper and lower sides of the periphery of the through groove;

[0012] A mounting bracket is provided on one side of the frame, and the mounting bracket is L-shaped.

[0013] The fixing frame is provided with a fixing component, which includes an upper fixing block and a lower fixing block;

[0014] The lower fixing block is V-shaped;

[0015] Both the upper and lower fixing blocks are slidably mounted on the fixing frame.

[0016] Through the above technical solution, the H-beam is fed to the cutting equipment by the feeding mechanism and passes through the through slot. The V-shaped structure of the lower fixing block supports the H-beam, which can increase the contact area between the H-beam and the lower fixing block. The upper fixing block fixes the top of the H-beam, and the upper and lower clamping blocks clamp the H-beam. Both the upper and lower clamping blocks have V-shaped structures, which makes the clamping of the H-beam more stable. By clamping and fixing both sides of the cutting area of ​​the H-beam with the clamping and fixing components, the stability of the H-beam cutting process can be improved, and the deviation of the H-beam during the cutting process can be avoided, thus preventing the cutting quality from being affected.

[0017] Furthermore, the upper clamping block is located to the right of the lower clamping block, and the staggered arrangement can better clamp and fix the H-beam.

[0018] Furthermore, the first mounting plate is provided with a first guide rail and a second guide rail;

[0019] The lower clamping block is slidably connected to the first guide rail via a first slider; the first mounting plate is provided with a first cylinder, and the output end of the first cylinder is connected to the lower clamping block.

[0020] The first mounting plate is provided with an adjustment plate, which is slidably connected to the second guide rail via a second slider;

[0021] The first mounting plate is equipped with a second cylinder, and the output end of the second cylinder is connected to the adjustment plate;

[0022] The lower clamping block is slidably mounted on the adjusting plate.

[0023] Furthermore, the adjustment plate is provided with a third slide rail, and the lower clamping block is slidably connected to the third guide rail via a third slider;

[0024] The lower clamping block and the adjusting plate are fixed together by bolts.

[0025] The above technical solution allows for the clamping of H-beams of different sizes by adjusting the position of the lower clamping block. The first cylinder moves the lower clamping block upward, and the second cylinder moves the upper clamping block downward through the adjusting plate, thereby clamping and fixing the upper and lower ends of the H-beam.

[0026] Furthermore, the fixing frame is provided with a fourth slide rail and a fifth slide rail;

[0027] The upper fixing block is slidably connected to the fourth slide rail via the fourth slider, and the fixing frame is equipped with a fourth cylinder, the output end of the fourth cylinder being connected to the upper fixing block;

[0028] The lower fixing block is slidably connected to the fifth slide rail via the fifth slider, and the fixing frame is equipped with a fifth cylinder, the output end of which is connected to the lower fixing block.

[0029] Furthermore, a motor is provided on the first mounting plate, and a drive gear is provided at the output end of the motor;

[0030] The second mounting plate is provided with a driven gear;

[0031] The driven gear is rotatably connected to the first mounting plate via a bearing;

[0032] The driven gear is concentrically arranged with the through slot;

[0033] The driving gear and the driven gear are meshed together.

[0034] The above technical solution uses a motor, a drive gear, and a driven gear to drive the second mounting plate to rotate, thereby realizing the rotation of the cutting assembly.

[0035] Furthermore, the cutting assembly includes a longitudinal linear module, a transverse linear module, a connecting plate, and a laser cutting head, wherein the longitudinal linear module is disposed on the second mounting plate; the longitudinal linear module is slidably disposed on the longitudinal linear module;

[0036] The connecting plate is slidably mounted on the horizontal linear module, and the laser cutting head is located on the side of the connecting plate.

[0037] Through the above technical solution, the horizontal linear module drives the connecting plate and the laser cutting head to move horizontally, and the vertical linear module drives the laser cutting head to move vertically, thereby adjusting the cutting distance between the laser cutting head and the H-beam for better cutting.

[0038] Furthermore, a protective cover is provided on the outside of the frame.

[0039] This utility model has the following beneficial effects:

[0040] 1. The H-beam passes through the through slot. The V-shaped structure of the lower fixing block supports the H-beam, increasing the contact area between the H-beam and the lower fixing block. The upper fixing block fixes the top of the H-beam.

Both the first mounting plate 11 and the second mounting plate 12 have circular through slots 13 for passing through the H-beam. A cutting assembly 2 is mounted on the second mounting plate 12, positioned above the through slots 13, and capable of longitudinal and lateral movement to cut the H-beam. A clamping assembly 3 is mounted on the first mounting plate 11, including an upper clamp.

The H-beam is fed to the cutting equipment by an external feeding mechanism, wherein the feeding mechanism is a conventional technology such as a conveyor belt or a robot, which is not shown in the attached drawings, and passes through the through slot 13. The V-shaped structure of the lower fixing block 43 supports the H-beam and can increase the contact area between the H-beam and the lower fixing block 43. Block 42 fixes the top of the H-beam.

The position of the lower clamping block 32 on the adjusting plate 38 is adjusted in advance according to the different sizes of H-beams, so that when the lower clamping block 32 moves down to clamp, it fits better with the upper end surface of the H-beam.

[0059] Specifically, the fixing frame 41 is provided with a fourth slide rail 44 and a fifth slide rail 47; the upper fixing block 42 is slidably connected to the fourth slide rail 44 through the fourth slider 45, and the fixing frame 41 is provided with a fourth cylinder 46, the output end of the fourth cylinder 46 is connected to the upper fixing block 42; the lower fixing block 43 is slidably connected to the fifth slide rail 47 through the fifth slider 48, and the fixing frame 41 is provided with a fifth cylinder 49, the output end of the fifth cylinder 49 is connected to the lower fixing block 43, the fifth cylinder 49 drives the lower fixing block 43 to move upward, so that the clamping surfaces of the lower fixing block 43 and the lower clamping block 32 for the H-beam are in the same plane, thereby ensuring that the positions of the two sides of the H-beam before and after cutting are horizontal, and avoiding the tilting of the cutting surface.

[0061] The working principle of this utility model is as follows: Before cutting, the upper fixing plate is adjusted to the position of the adjusting plate 38 according to the rack of the H-beam to be cut, so that the inner corner of the upper fixing plate is directly above the top of the H-beam during conveying. After adjustment, the upper fixing plate is fixed by bolts 312. The H-beam passes through the through groove 13. The fifth cylinder 49 drives the lower fixing block 43 to move upward, supporting the H-beam and positioning it in the center of the through groove 13 without contacting the inner wall of the through groove 13. The fourth cylinder 4... 6 drives the upper fixing block 42 to move down and abut against the top of the H-beam; the upper clamping block 31 of the clamping assembly 3 moves down and the lower clamping block 32 moves up to clamp the upper and lower ends of the H-beam, thereby fixing both sides of the cutting area of ​​the H-beam. Then, the transverse linear module 22 drives the laser cutting head 24 to move laterally, and the longitudinal linear module 21 drives the laser cutting head 24 to move longitudinally.
