An over-position laser cutting structure for a large-diameter, heavy-duty laser pipe cutting machine

Abstract

An over-the-horizon laser cutting structure for a large-diameter, heavy-duty laser pipe cutting machine includes: a conveyor base, a laser cutting machine base, and a clamp assembly, a cutting movable seat, a cutting moving mechanism, and a laser cutting head disposed on the laser cutting machine base. The cutting moving mechanism can move the cutting movable seat laterally to allow the laser cutting head to cut the pipe. The cutting moving mechanism can also move the cutting movable seat along the extension direction of the conveyor base to allow the cutting movable seat to cut the pipe from the front or rear side of the clamp assembly. This invention fundamentally eliminates the waste problem of "clamping section residue" that inevitably occurs due to clamp fixation in traditional methods. This maximizes the effective utilization rate of the entire pipe to nearly 100%, which is particularly significant for expensive large-diameter, heavy-duty pipes, resulting in substantial economic benefits.

Description

Technical Field

[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to an over-position laser cutting structure for a large-diameter heavy-duty laser tube cutting machine. Background Technology

[0002] Laser cutting technology, with its significant advantages such as high precision, high efficiency, and non-contact processing, has become a key process for cutting and engraving metal and non-metal materials in modern manufacturing. Laser tube cutting machines, as an important application of this technology, are specifically used for cutting tubes to a fixed length. When handling heavy-duty tubes with large diameters, long spans, and high weights, the equipment is typically equipped with a long conveyor base. During the cutting process, one end of the tube is clamped and fixed by a clamp assembly fixed to the conveyor base, while the cutting of the other end is completed by the laser cutting assembly.

[0003] However, this existing technology has a significant drawback: whether cutting the beginning or end of the pipe, a clamp assembly is required to forcefully clamp and fix the pipe. This clamping method results in the pipe section covered by the clamp (the clamped section) being unusable as usable material after cutting. This residual clamped section material directly wastes material and significantly reduces the actual utilization rate of the entire pipe, especially for costly, heavy-duty pipes. This problem urgently needs to be solved. Therefore, it is imperative to improve the pipe fixing and cutting methods of existing laser pipe cutting machines to minimize or eliminate residual clamped section material and improve material utilization efficiency. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes an off-center laser cutting structure for a large-diameter, heavy-duty laser pipe cutting machine.

[0005] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: an over-position laser cutting structure for a large-diameter heavy-duty laser pipe cutting machine, including: a conveyor base, a laser cutting machine base, and a clamp assembly, a cutting movable seat, a cutting moving mechanism, and a laser cutting head disposed on the laser cutting machine base;

[0006] The laser cutting machine base is disposed at one end of the conveyor base; the conveyor base is used to convey the pipe material forward; the caliper assembly is used to clamp the pipe material; the laser cutting head is disposed on the cutting movable seat and is used to cut the pipe material; the cutting moving mechanism can move the cutting movable seat laterally so that the laser cutting head cuts the pipe material; the cutting moving mechanism can move the cutting movable seat along the extension direction of the conveyor base so that the cutting movable seat cuts the pipe material from the front or rear side of the caliper assembly.

[0007] Optionally, the cutting moving mechanism includes a first moving component, a transverse worktable, and a second moving component; the cutting movable seat and the first moving component are disposed on the transverse worktable; the transverse worktable spans above the laser cutting machine base; the first moving component allows the cutting movable seat to move on the transverse worktable so that the laser cutting head cuts the pipe;

[0008] The second moving assembly is used to move the transverse worktable along the extension direction of the conveyor base and to make the cutting movable seat and the laser cutting head cut the pipe from the front or rear side of the caliper assembly.

[0009] Optionally, the transverse worktable is provided with a first moving track extending laterally along the conveyor base, and the cutting movable seat is movably mounted on the first moving track.

[0010] Optionally, the laser cutting machine base is provided with a second moving track extending along the extension direction of the conveyor base, and the transverse worktable is movably mounted on the second moving track.

[0011] Optionally, the conveyor base is provided with a plurality of movable clamps; the movable clamps are spaced apart on the conveyor base to spacedly clamp and support the lower part of the pipe material.

[0012] Optionally, the conveyor base is provided with an end pusher; the end pusher is located on the conveyor base away from the laser cutting machine base and is used to push the tube toward the laser cutting machine base.

[0013] The beneficial effects of this invention are as follows: The cutting laser assembly can drive the cutting movable seat, together with the laser cutting head, to move along the extension direction of the conveyor base, enabling it to cut in front of or behind the caliper assembly. When it is necessary to cut the end of the pipe, the laser cutting head can pass over the caliper assembly and move behind it to perform the cutting operation. At this time, the pipe segment clamped by the caliper assembly is the "waste" part that has already been cut off, that is, the part that is no longer needed for subsequent processing, rather than the main part of the pipe to be used. Therefore, the caliper clamping area itself is no longer included in the final usable pipe segment, fundamentally eliminating the problem of "clamping segment waste" that is inevitably caused by caliper fixation in traditional methods. This allows the effective utilization rate of the entire pipe to be maximized to nearly 100%, which is especially significant for expensive, large-diameter, heavy-duty pipes.

[0025] Example

[0026] Reference Figures 1 to 3 The present invention proposes an over-position laser cutting structure for a large-diameter heavy-duty laser pipe cutting machine, comprising: a conveyor base 10, a laser cutting machine base 20, a clamp assembly 30, a cutting movable base 40, a cutting moving mechanism 50, and a laser cutting head 60 disposed on the laser cutting machine base 20.

[0027] A laser cutting machine base 20 is disposed at one end of a conveyor base 10; the conveyor base 10 is used to transport the pipe material forward; a clamp assembly 30 is used to clamp the pipe material; a laser cutting head 60 is disposed on a cutting movable seat 40 for cutting the pipe material; a cutting moving mechanism 50 can move the cutting movable seat 40 laterally so that the laser cutting head 60 cuts the pipe material; the cutting moving mechanism 50 can move the cutting movable seat 40 along the extension direction of the conveyor base 10 so that the cutting movable seat 40 cuts the pipe material from the front or rear side of the clamp assembly 30.

[0028] In this invention, the cutting laser assembly drives the cutting movable seat 40, together with the laser cutting head 60, to move along the extension direction of the conveyor base 10, enabling it to perform cutting in front of or behind the clamp assembly 30. When it is necessary to cut the end of the pipe, the laser cutting head 60 can pass over the clamp assembly 30 and move behind it to perform the cutting operation. At this time, the pipe segment clamped by the clamp assembly 30 is the "waste" part that has already been cut off, that is, the part that is no longer needed for subsequent processing, rather than the main part of the pipe to be used. Therefore, the clamping area itself is no longer included in the final usable pipe segment, fundamentally eliminating the problem of "clamping segment waste" that is inevitably caused by clamp fixation in traditional methods. This allows the effective utilization rate of the entire pipe to be maximized to nearly 100%, which is especially significant for expensive, large-diameter, heavy-duty pipes.

[0029] In this embodiment, the cutting moving mechanism 50 includes a first moving component 51, a transverse worktable 52, and a second moving component 53; the cutting movable seat 40 and the first moving component 51 are disposed on the transverse worktable 52; the transverse worktable 52 spans above the laser cutting machine base 20; the first moving component 51 allows the cutting movable seat 40 to move on the transverse worktable 52 so that the laser cutting head 60 cuts the pipe; the second moving component 53 is used to move the transverse worktable 52 along the extension direction of the conveyor base 10, and to allow the cutting movable seat 40 and the laser cutting head 60 to cut the pipe from the front or rear side of the clamp assembly 30.

[0030] Through a layered movement design (the first moving component 51 controls the transverse cutting, and the second moving component 53 controls the axial overrun), the transverse cutting and axial overrun are driven by independent components, avoiding motion interference and ensuring the accuracy of the cutting trajectory. The transverse worktable 52 serves as a load-bearing base, providing stable support for the cutting movable seat 40, suppressing vibrations during large-diameter pipe cutting, improving rigidity and stability, and ensuring cut quality.

[0031] Specifically, the transverse worktable 52 is equipped with a first moving track 54 extending transversely along the conveyor base 10, and the cutting movable seat 40 is movably mounted on the first moving track 54. The track is arranged strictly transversely along the conveyor base 10 (perpendicular to the pipe axis) to ensure that the laser head cutting movement is absolutely perpendicular to the pipe axis, avoiding oblique cuts. The track load-bearing structure is designed to be reinforced against the radial impact force of large-diameter pipe cutting, preventing track deformation when cutting thick-walled pipes, and has high load stability.

[0032] Furthermore, the laser cutting machine base 20 is equipped with a second moving track 21 extending along the extension direction of the conveyor base 10, and the transverse worktable 52 is movably mounted on the second moving track 21. This ensures precise and controllable overtravel travel.

[0033] In this embodiment, the conveyor base 10 is provided with a plurality of movable clamps 11; the movable clamps 11 are spaced apart on the conveyor base 10 and are used to clamp and support the lower part of the pipe material at intervals. The clamps support the entire length of the pipe material at intervals, disperse the gravity load, effectively control the bending deformation of the pipe material, prevent the sagging of large-span pipe materials, and ensure the straightness of the cut.

[0034] In this embodiment, the conveyor base 10 is provided with an end pusher 12; the end pusher 12 is located on the conveyor base 10 away from the laser cutting machine base 20, and is used to push the tube towards the laser cutting machine base 20. The hydraulically / servo-driven pusher pushes the tube towards the laser station with a constant thrust, maintaining the continuous and stable feeding of heavy-duty tubes. The pusher is linked with the conveyor base 10, and after completing one cut, it automatically pushes the remaining section of the tube to the next station, realizing unattended batch processing.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
