Description

Technical Field

[0001] The utility model relates to the technical field of pipeline cutting, in particular to a high-flatness pipeline cutting device. Background Art

[0002] Pipe cutting device is a mechanical equipment specially designed for cutting, segmenting or cutting pipes into specific shapes and sizes. It usually consists of a fixing and clamping system, a cutting tool, a drive and control system and a drive and control system.

[0003] During the cutting process, existing pipe cutting devices often cause the pipe to shake due to the insufficient stability of the clamping system, making it difficult to achieve high flatness requirements on the cut surface, resulting in obvious unevenness and jagged edges. Traditional saw blades or simple flame cutting methods cannot accurately control the distribution of cutting energy, resulting in uneven heating of the cut surface, large thermal deformation, and seriously affecting flatness.

[0004] Therefore, in view of the fact that the existing pipe cutting device has an unstable clamping system that causes the pipe to shake and the uneven cutting surface, and the traditional cutting saw blade or simple flame cutting has difficult to control the energy distribution, and the uneven heating causes thermal deformation, which further leads to the uneven cutting surface, we have proposed a high-flatness pipe cutting device to solve the above problems. Utility Model Content

[0005] In order to overcome the problem of unstable clamping system in existing pipe cutting devices causing pipe shaking and uneven cutting surface, the energy distribution of traditional cutting saw blades or simple flame cutting is difficult to control, and uneven heating causes thermal deformation, which further leads to uneven cutting surface.

[0006] The technical solution of the utility model is: a high-flatness pipe cutting device, including a machine, a clamp module, a laser cutting module and a power supply; a clamp module for fixing the pipe is installed at the center of the top of the machine, a power supply for providing stable power to the entire device is installed at the corner of the top of the machine, a laser cutting module for cutting the pipe is installed at the top of the machine parallel to the power supply, and the laser cutting module includes a first-level hydraulic support arm, a first-level sheath, a first-level hydraulic cylinder, a hydraulic distribution valve, a hydraulic motor, a second-level hydraulic cylinder, a second-level sheath, a second-level hydraulic support arm, a laser cutting head, a laser setting table and a ventilation slot; two groups of first-level hydraulic support arms are symmetrically arranged, the top of the two groups of first-level hydraulic support arms are both covered with a first-level sheath, and the top of the two groups of first-level sheaths are both equipped with a first-level hydraulic cylinder.

[0007] Preferably, the pipe is fixed by a clamp module and combined with a laser cutting module to achieve precise cutting of the pipe. Whether in mass production or single-piece customization, the dimensional accuracy and surface quality of the pipe cutting can be ensured, meeting application scenarios with extremely high requirements for pipe cutting accuracy. The combination of multi-stage hydraulic support arms and hydraulic cylinders enables the laser cutting head to be flexibly adjusted in multiple dimensions. This high flexibility enables it to adapt to the cutting needs of pipes of various sizes, shapes and materials. The power supply is installed at the top corner of the machine, which can provide stable power support and reduce equipment failures and production interruptions caused by power fluctuations.

The combination of the linear guide rail and the slider can provide high-precision guidance for the movement of the laser cutting head, ensuring that it can accurately reach the predetermined position during the cutting process, thereby improving the cutting accuracy. The hydraulic motor and the hydraulic distribution valve help to optimize the layout of the hydraulic system, reduce the complexity of the pipeline, and improve the stability and reliability of the hydraulic transmission.

[0009] Preferably, a secondary hydraulic cylinder is installed at the bottom end of the slider on the linear guide rail, a secondary sheath is installed at the bottom end of the secondary hydraulic cylinder, a secondary hydraulic support arm for extension and retraction is embedded inside the secondary sheath, a laser cutting head is installed at the front end of the secondary hydraulic support arm, a laser generator is provided inside the laser cutting head, the hydraulic distribution valve is respectively connected to the primary hydraulic cylinder and the secondary hydraulic cylinder through hydraulic pipelines, the hydraulic motor is electrically connected to the hydraulic distribution valve, and the combination of the secondary hydraulic cylinder and the secondary hydraulic support arm can realize precise extension and retraction adjustment of the laser cutting head, so that the cutting head can approach and cut the pipeline more accurately, thereby improving the cutting accuracy.

[0010] Preferably, there is a laser setting table on one side of the machine, with multiple sets of ventilation slots on both sides of the laser setting table from top to bottom, and multiple sets of heat dissipation slots at the rear end of the laser setting table. A laser control screen is installed above the front end of the laser setting table, and the laser setting table is connected to the laser cutting head through an optical fiber. The ventilation slots on both sides of the laser setting table and the heat dissipation slots at the rear end can effectively dissipate the heat generated inside the laser setting table, ensuring that the equipment will not malfunction or performance degradation due to overheating during long-term operation.

The first-level support rod provides the main support for the fixture module to ensure its stability during work. The second-level support rods on both sides further assist in supporting the fixture module so that it can withstand various forces generated during pipe cutting, reduce shaking and displacement, and thus improve cutting accuracy.

[0012] Preferably, the clamp module includes an electric rotating outer ring, an electric rotating inner ring, a chuck body, a clamping claw, a connecting shaft, a cylinder and a rotating motor; a rotating motor is installed above the rear end of the electric rotating outer ring, and the electric rotating inner ring is embedded in the electric rotating outer ring.

[0013] Preferably, the chuck body is equipped with three sets of jaws, and the chuck body is provided with square slide grooves for installing the three sets of jaws. Cylinders are provided on the top of the three sets of jaws, and the cylinders drive the three sets of jaws to extend and retract. The design of the three sets of jaws can evenly apply force to clamp the pipe from three directions, providing a more stable and balanced clamping force, effectively preventing the pipe from loosening or rotating during processing. The way the cylinder drives the jaws to extend and retract allows the jaws to be flexibly adjusted according to the diameter of the pipe, thereby adapting to the clamping needs of pipes of different diameters.

[0014] Beneficial effects of the utility model:

[0015] 1. The combination of the motorized rotating outer ring, inner ring, and chuck body in the clamp module enables precise rotational positioning. This allows for flexible adjustment of the pipe's angle and position during the cutting process, enabling complex shapes and high-precision cutting. The three sets of jaws, driven by a pneumatic cylinder, extend and retract to accommodate pipes of varying diameters and provide uniform and powerful clamping force. This stable clamping ensures that the pipe does not shift or deform during cutting, improving cutting accuracy and quality.

[0016] 2. The multi-stage hydraulic support arm and hydraulic cylinder in the laser cutting module provide stable and precise positioning of the laser cutting head. This enables the laser cutting head to approach the pipe at the optimal angle and distance for cutting, thus achieving an efficient and rapid cutting process. Laser cutting itself has the characteristics of a small heat-affected zone and high cut surface flatness. Combined with the stable support structure, it can ensure that the cut pipe surface is smooth and flat, eliminating the need for subsequent extensive grinding, saving processing time and cost.
