Description

Technical Field

[0001] The utility model relates to the technical field of pipe processing, in particular to a laser cutting machine special for pipes with stable cutting performance. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to melt, vaporize or reach ignition point rapidly, and at the same time uses a high-speed airflow coaxial with the beam to blow away the molten material, thereby achieving the cutting of the workpiece. It is one of the thermal cutting methods for cutting workpieces, which can be divided into four categories: laser vaporization cutting, laser melting cutting, laser oxygen cutting, and laser scribing and controlled fracture.

[0003] The patent specification with announcement number CN211305241U discloses a laser cutting machine for pipes, including a hollow workbench, guide rails are installed at both ends of the workbench, a Z-axis electric slider is movably provided at one end of the guide rail, a Y-axis electric slider is connected to the outer side of the Z-axis electric slider, a laser cutting gun is installed above the lower end of the workbench, a clamping mechanism is provided near the front of the guide rail at both ends of the upper part of the workbench, the clamping mechanism includes a support frame, a cylinder, and a fixed plate, a control panel is provided on the outer surface of one end of the workbench, and two groups of slide grooves are symmetrically provided on the inner surface of the workbench. The laser cutting machine for pipes described in the utility model can fix the pipes firmly, avoid rolling of the pipes during cutting, and make the cutting quality of the pipes better. It can be used for cutting pipes of different thicknesses, and can collect iron slag, which is convenient for cleaning the iron slag.

[0004] However, in the implementation of relevant technologies, it was found that the above-designed dedicated laser cutting machine for pipes has the following problems: in the prior art, components such as a support frame are used to stably clamp the pipe during processing, but the clamping surface is too smooth during the clamping process, and sliding may occur during the clamping process, resulting in unstable clamping of the pipe. In view of this, a dedicated laser cutting machine for pipes with stable cutting is provided to overcome the above-mentioned defects. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and proposes a special laser cutting machine for pipes with stable cutting performance.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a laser cutting machine for pipes with stable cutting, comprising an operating table, a cutting box is fixed on one side above the operating table, through holes are opened on both sides of the outer wall of the cutting box, and a clamping mechanism is arranged above the cutting box;

[0007] The clamping mechanism includes a support frame, which is fixedly installed on the top of the cutting box, and a hydraulic rod is embedded on the top of the support frame. The power output end of the hydraulic rod is connected to a lower pressure frame, and a radian plate is fixed to the bottom end of the lower pressure frame. The radian plate is an arc-shaped structure, which facilitates the fitting and limiting of the pipe to avoid slipping.

[0008] As a further description of the above technical solution: the structure of the lower pressure frame is a U-shaped structure, and the lower pressure frame is detachably connected to the radian plate by bolts. The radian plate can be replaced by bolts, and the applicability can be improved by replacing it according to the pipe model.

[0009] As a further description of the above technical solution: a support rod is fixed to one side of the cutting box at the top of the operating table, and a receiving plate is fixed to the top of the support rod, so that the pipes can be supported via the support rod and the receiving plate. At the same time, the receiving plate is semi-arc-shaped and can limit the position of the pipes.

[0010] As a further description of the above technical solution: a damping spring is embedded in the inner wall of the through hole, and one end of the damping spring passing through the through hole is connected to a supporting plate. When the pipe passes through the through hole, under the pressure of the arc plate, the supporting plate is elastically pushed by the damping spring to further clamp the pipe and keep it stable.

[0011] As a further description of the above technical solution: a mounting shell is fixed to the outer wall of the operating table, and a pushing mechanism is arranged inside the mounting shell, and the mounting shell is used to support and install the pushing mechanism.

[0012] As a further description of the above technical solution: the pushing mechanism includes a motor, the motor is embedded in one side of the outer wall of the mounting shell, and the power output end of the motor is connected to a threaded rod, the outside of the threaded rod is slidably connected to a pushing plate, and the mounting shell is provided with a sliding groove corresponding to the position of the pushing plate. The threaded rod is driven by the motor to allow the pushing plate to slide along the sliding groove, pushing the pipe to slide and adjust the cutting position, thereby facilitating multiple segmentation of a pipe to avoid excessive troublesome manual operation.

[0013] As a further description of the above technical solution: a conveying assembly is arranged above the interior of the cutting box, and the bottom end of the conveying assembly is slidably connected to the laser cutting equipment body. The structure of the conveying assembly is consistent with the pushing mechanism, so that it can drive the laser cutting equipment body to move and cut the pipe.

[0014] The utility model has the following beneficial effects:

[0015] The utility model designs a special laser cutting machine for pipes with stable cutting. The pipes are preliminarily supported by the cooperation of support rods and receiving plates. When cutting, the lower pressing frame is pushed by the hydraulic rod to allow the arc plate to press the pipe against the receiving plate. Both the arc plate and the receiving plate are semi-arc-shaped, so that they can fit and press the pipe to avoid looseness or shaking, thereby improving the stability of the cutting process.

[0016] The utility model designs a special laser cutting machine for pipes with stable cutting. The motor drives the threaded rod to rotate, so that the pushing plate slides along the slide groove on the mounting shell, thereby pushing the pipe to slide on the receiving plate, and automatically loading the pipe, avoiding the high labor intensity of manual pushing and placement.

[0024] As a further implementation scheme of the above technical scheme: the structure of the lower pressure frame 403 is a U-shaped structure, and the lower pressure frame 403 is detachably connected to the curvature plate 404 by bolts. The curvature plate 404 can be replaced by bolts, and the applicability can be improved by replacing it according to the pipe model.

The support rod 5 and the receiving plate 6 are convenient for supporting pipes. At the same time, the receiving plate 6 is semi-arc-shaped and can limit the position of the pipes.

[0026] During specific implementation, the pipe is supported on the operating table 1 by the support rod 5 and the receiving plate 6, passes through the cutting box 2 through the through hole 3, and the hydraulic rod 402, under the support and fixation of the support frame 401, pushes the lower pressure frame 403, so that the arc plate 404 presses the pipe tightly on the receiving plates 6 close to the two sides of the cutting box 2, thereby achieving a certain limiting and stabilizing effect to avoid shaking during cutting.

[0027] As a further implementation scheme of the above technical scheme: a damping spring 8 is embedded in the inner wall of the through hole 3, and one end of the damping spring 8 passing through the through hole 3 is connected to a supporting plate 7. When the pipe passes through the through hole 3, under the pressure of the arc plate 404, the damping spring 8 elastically pushes the supporting plate 7 to further clamp the pipe and keep it stable.
