Description

Technical Field

[0001] The utility model relates to the technical field of protective devices, in particular to a beam protective device for a laser cutting machine. Background Art

[0002] With the continuous development of industrial manufacturing, large-format laser cutting machines are increasingly used in a variety of industries, including metal processing, advertising production, and automotive manufacturing. However, laser cutting machines can generate dangerous factors such as high temperatures and laser radiation during operation. Therefore, adding protective enclosures is crucial to ensure efficient, stable, and safe operation of laser cutting machines, safeguarding both equipment and operators.

[0003] In order to ensure the safety of equipment and personnel, Chinese patent CN108838570A, a laser cutting machine beam protection device, points out that the protection device moves with the help of guide rails, using the guide rails as a support and guiding medium, which simplifies the installation structure of the protection device, making the structure of the protection device more reasonable and easier to install. It has low noise during use and can effectively protect the transmission components on the beam. Although the above patent can protect the components on the beam and ensure the safety of equipment, it still has certain shortcomings. Most of the laser cutting machines with enclosure protection are small-format equipment. For large-format laser cutting machines, the traditional enclosure method is too bulky, costly, and complex in structure. The patent cannot effectively prevent the dangerous factors of high temperature and laser radiation, so it is not good in terms of personnel safety.

[0004] Therefore, in order to ensure the safety of equipment and operators on the basis of a simple structure, a laser cutting machine beam protection device is proposed to solve the technical problems existing in the prior art. Utility Model Content

[0005] In response to the deficiencies of the existing technology, the utility model provides a laser cutting machine beam protection device, which solves the problem that the existing laser cutting machine protection structure can effectively protect the laser cutting machine equipment but cannot effectively guarantee the safety of personnel.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser cutting machine beam protection device, comprising a cutting machine beam, a protective structure wrapped around the cutting machine beam, the protective structure being connected to the cutting machine beam and moving with the cutting machine beam, the protective structure comprising a rear side frame, a front side frame, a connecting frame, a front observation door, a side observation door, a beam connecting plate, and a side frame, a connecting frame being connected between the rear side frame and the front side frame, a side frame being connected at the side ends of the rear side frame and the front side frame, a beam connecting plate being installed on the side frame, the beam connecting plate being connected to the cutting machine beam, a front observation door being provided on the surface of the front side frame, a layer of sheet metal being provided on the surface of the rear side frame, a side observation door being provided on the surface of the side frame, and a transfer connecting plate being provided at the connection between the side frame and the rear side frame and the front side frame.

[0007] Through the above technical solution, further, the front side and the rear side of the side observation door are both provided with mounting frames, and the mounting frames are provided with safety gratings.

[0008] Furthermore, fire curtains are provided at the lower ends of the rear frame and the front frame.

[0009] As a preferred technical solution, a support rod is provided on one side of the front frame, and the support rod is connected to the crossbeam connecting plate.

[0010] Furthermore, a movable door is provided at the front end of the front frame, and the movable door includes a guide rail, a slider, and a movable door. The guide rail is installed at the upper end of the front frame, and a slider is movably provided on the guide rail, and the movable door is connected to the surface of the slider.

[0011] As a preferred technical solution, an L-shaped connecting plate is further installed at the upper end of the front frame, and a blocking ring is provided on one side of the L-shaped connecting plate.

[0012] Compared with the existing technology, the utility model provides a laser cutting machine beam protection device, which has the following beneficial effects:

[0013] 1. This protective device specifically wraps the crossbeam through a protective structure, and the protective structure is connected to the crossbeam, moves with the crossbeam, and realizes large-scale protection in a simple structure.

[0014] 2. Fix the surrounding sheet metal on the protective structure so that the surrounding can move with the beam to prevent damage from laser radiation and spark splashing. The sheet metal has low production cost and good protection effect.

[0015] 3. Safety light curtains can monitor the movement of people in the production area in real time. When a person or object passes through the light curtain formed by the safety light curtain, the safety light curtain will immediately detect and trigger safety mechanisms such as shutdown or alarm. This rapid response mechanism effectively prevents workers from coming into contact with the danger zone, thereby avoiding mechanical injuries and protecting the personal safety of workers.

[0016] 4. Through the fire curtain, while ensuring the material passing height, the protective performance of the beam enclosure is further increased, effectively blocking the harm of laser radiation to the human body, and at the same time increasing the sealing. If a dust suction fan is installed on the protective structure, the dust suction effect can be improved. BRIEF DESCRIPTION OF THE DRAWINGS
