Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser cutting equipment technology, and in particular to a worktable for an integrated high-power laser cutting machine. Background Technology
[0002] Laser cutting technology, with its high precision, high efficiency, and non-contact processing characteristics, has become a core process for cutting and engraving metallic and non-metallic materials in modern manufacturing. Its basic principle is to use a high-energy laser beam focused by an optical system to form an extremely small spot, causing the material to reach a critical temperature for melting, vaporization, or ablation in a localized area, thereby achieving precise material separation and pattern formation. With the increasing demands for processing efficiency and thickness control in industrial applications, the adoption rate of high-power laser cutting equipment (such as those exceeding 10,000 watts) has significantly increased.
[0003] However, the massive amount of heat released by high-power lasers during high-speed cutting poses a severe challenge to the thermal stability of the equipment structure. In typical industrial laser cutting equipment, the worktable usually consists of parallel track seats on both sides and several crossbeams bridging them. The track seats support the cutting head movement system, while the crossbeams together enclose the cutting working cavity. During continuous high-power operation, the high-temperature heat accumulated in the cutting area is rapidly dissipated through thermal radiation and gas convection. The localized temperature rise of the crossbeams and track seats causes uneven thermal expansion, and the thermal deformation effect damages their geometric accuracy, directly affecting the misalignment of the motion system, namely the positioning accuracy and dynamic response performance of the cutting head; accelerating the fatigue of mechanical components and reducing the equipment's lifespan.
[0004] This issue has become a key technological bottleneck restricting the development of laser cutting equipment to higher power levels. While existing worktable structures can meet the heat dissipation requirements under normal power conditions, traditional passive cooling methods are insufficient in extreme operating conditions exceeding 10,000 watts. Therefore, it is urgent to design a new worktable structure with an efficient heat-blocking mechanism to fundamentally suppress the transfer of heat to key components of the moving mechanism, thereby ensuring the precision stability and equipment durability of high-power laser cutting.

[0014] Optionally, a baffle plate is provided below the side of the track seat facing the working chamber. The baffle plate is located below the intelligent dust removal and heat dissipation air duct and is used to cover the gap between the side of the working chamber and the track seat.

[0032] Example
[0033] Reference Figures 1 to 4 The present invention proposes an integrated high-power laser cutting machine worktable, which includes parallel rail seats 10 on both sides and several crossbeams 20 connected across them, and a working area is formed between the rail seats 10 on both sides.
[0034] A vertically arranged partition plate 30 is provided above the crossbeam 20; the partition plate 30 divides the working area into several working chambers 40; a heat insulation protective plate 50 is provided on the outside of the partition plate 30; the heat insulation protective plate 50 and the partition plate 30 form a heat insulation cavity 60, which is used to separate the crossbeam 20 from the working chambers 40; the track seat 10 is provided with an intelligent dust removal and heat dissipation duct 70; a heat dissipation port 71 is opened on one side of the intelligent dust removal and heat dissipation duct 70, which connects the intelligent dust removal and heat dissipation duct 70 and the working chambers 40; a heat dissipation fan 72 is connected to the intelligent dust removal and heat dissipation duct 70.
[0035] The beneficial effects of this utility model are as follows: By integrating the heat insulation and protective plate 50, the partition plate 30, and adding a refractory brick composite structure and an active heat dissipation and dust removal system, this utility model significantly improves the thermal stability and processing accuracy of the high-power laser cutting worktable, specifically manifested in:
[0036] 1. Enhanced heat conduction blocking: The heat insulation cavity 60, formed by the partition plate 30 and the heat insulation protection plate 50, constructs a physical isolation barrier between the crossbeam 20 (3) and the working cavity 40, effectively blocking the radiant heat of the cutting area from being transmitted to the crossbeam 20, eliminating the deformation of the crossbeam 20 caused by thermal expansion, and ensuring the geometric accuracy of the workbench basic structure.
[0037] 2. Active heat dissipation structure: The intelligent dust removal and heat dissipation air duct 70 built into the track base 10 is directly connected to the working chamber 40 through the heat dissipation port 71. Driven by the heat dissipation fan 72, the high-temperature smoke and hot air under the cutting head are extracted in real time, eliminating the accumulation of heat in the working chamber 40 and the path of heat conduction to the track base 10, thus achieving the effect of active heat dissipation and exhaust.
[0038] In this embodiment, a second protective cover 31 is fitted over the partition plate 30. The second protective cover 31 on the top of the partition plate 30 forms a vertical thermal barrier, which blocks the high-temperature airflow from eroding the top structure of the partition plate 30 and also prevents debris falling from the working chamber 40 from eroding the partition plate 30.
[0039] In this embodiment, a third protective plate 11 is provided on the side of the track seat 10 facing the working chamber 40; the third protective plate 11 is located above the heat dissipation port 71. The third protective plate 11 above the heat dissipation port 71 prevents splashed molten slag from entering the air duct, blocking and affecting the intelligent dust removal and heat dissipation air duct 70, and avoiding the reduction of heat dissipation efficiency.
[0040] Preferably, the heat insulation plate 50, the second protective cover 31, and the third protective plate 11 are made of copper plate and / or graphite plate. Copper plate and graphite plate have both high thermal conductivity and low coefficient of thermal expansion, which can effectively conduct and diffuse the heat of the working cavity 40 to the air duct for exhaust and heat dissipation, while blocking the transfer of heat to the crossbeam 20 or the track seat 10.
[0041] In this embodiment, the heat insulation cavity 60 is lined with several heat insulation bricks. The heat insulation bricks inside the heat insulation cavity 60 form a multi-layer heat insulation barrier, which further reduces the thermal conductivity of the crossbeam 20 and the working cavity 40, and further reduces the impact of thermal deformation on the flatness of the crossbeam 20.
[0042] In this embodiment, a partition plate 41 is provided at the middle of two adjacent crossbeams 20 along the extension direction of the track seat 10; the partition plate 41 divides the working chamber 40 laterally. The partition plate 41 between the crossbeams 20 divides the working chamber 40 laterally, limiting the diffusion range of the high temperature area. The working chambers 40 on both sides can respectively dissipate heat through the intelligent dust removal and heat dissipation air ducts 70 of the track seats 10 on both sides, achieving targeted and effective heat dissipation and exhaust.
[0043] In this embodiment, a material cart bottom plate 42 is provided below the working chamber 40 to cover the bottom of the working chamber 40. The bottom material cart bottom plate 42 blocks the overflow path of high-temperature gas, forcing the hot gas to flow in a directional direction to the heat dissipation port 71 of the track seat 10, while achieving the effect of collecting dust and cutting slag.
[0044] Furthermore, a baffle plate 43 is provided below the side of the track seat 10 facing the working chamber 40. The baffle plate 43 is located below the intelligent dust removal and heat dissipation air duct 70 and is used to cover the gap between the side of the working chamber 40 and the track seat 10. The baffle plate 43 below the track seat 10 seals the lateral gap of the working chamber 40, eliminates the airflow short circuit phenomenon, ensures the effective coverage of the negative pressure of the intelligent dust removal and heat dissipation air duct 70, and forces the hot air to flow directionally towards the heat dissipation port 71 of the track seat 10.
[0045] In this embodiment, the cooling fan 72 is located at the front or rear end of the workbench and is provided with a transverse air duct 73 extending along the crossbeam 20; the transverse air duct 73 simultaneously connects to two intelligent dust removal and cooling air ducts 70 on both sides of the track seats 10. This achieves balanced air extraction from a single fan in two paths, reducing energy consumption, and the air duct extending along the crossbeam 20 optimizes the uniformity of airflow distribution.
[0046] In this embodiment, the heat insulation plate 50 has several bypass air slots 51 that connect to the heat insulation cavity 60. The bypass air slots 51 of the heat insulation plate 50 establish micro-circulation air cooling for the heat insulation cavity 60, avoid heat retention inside the cavity, and balance the air pressure inside and outside the cavity to prevent the protective plate from deforming due to heat.
[0047] In this embodiment, the track base 10 is provided with an opening and closing baffle 80 and an opening and closing telescopic drive 81 on the side facing the working chamber 40. The opening and closing telescopic drive 81 is used to move the opening and closing baffle 80 so that the opening and closing baffle 80 opens or closes the heat dissipation port 71 corresponding to the working chamber 40. The opening and closing baffle 80 is controlled by the telescopic drive to open and close the heat dissipation port 71 of a specific working chamber 40 as needed: during processing, the heat dissipation port 71 of the corresponding area is opened to accurately and powerfully draw in high-temperature gas; the heat dissipation port 71 of the unprocessed area is not opened to reduce the loss of negative pressure in the intelligent dust removal and heat dissipation duct 70.
[0048] Preferably, the track base 10 is provided with a guide post 82; the opening and closing baffle 80 has a guide elongated hole 83; the guide post 82 passes through the guide elongated hole 83. The guide post 82 and the elongated hole form a sliding pair to ensure the precise movement trajectory of the opening and closing baffle 80, avoid jamming, and ensure the reliability of temperature control in the 40 zones of the multi-working chamber.
[0049] In this embodiment, the opening and closing telescopic drive component 81 is a telescopic motor. The telescopic motor supports real-time dynamic air control linked to the movement of the cutting head, adapting to the transient thermal management requirements of high-speed cutting.
[0050] 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.
