Description

Technical Field

[0001] The invention relates to the technical field of laser cutting machines, in particular to a laser cutting machine with a hard and brittle material anti-cracking function. Background Art

[0002] The laser cutting machine is a machine that emits laser light, which is focused into a high-power density laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. Each high-energy laser pulse instantly sputters a tiny hole on the surface of the object. Under computer control, the laser processing head and the material being processed perform continuous relative motion and dotting according to a pre-drawn pattern, thus processing the object into the desired shape. At the same time, high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Laser cutting replaces the transmission line with an invisible beam. Traditional mechanical knives have the characteristics of high precision, fast cutting, no restrictions on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. They will gradually improve or replace traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the workpiece and will not scratch the surface of the workpiece during work; the laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is required; the cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow; the incision has no mechanical stress and no shear burrs; the processing accuracy is high, the repeatability is good, and the material surface is not damaged; CNC programming can process any plane diagram, and can cut a large whole plate without opening a mold, which is economical and time-saving.

[0003] After searching, the patent number CN115194346B discloses that the present invention relates to the field of laser cutting, and in particular to a laser cutting machine. Technical problem: When cutting pipes, holes will be opened in the pipes as needed. After the holes are opened by laser cutting, cutting debris will remain stuck in the holes. Technical solution: A laser cutting machine includes a base, a first mounting plate, a first mounting frame, a first collection box, a second collection box and a third collection box, etc.; the first mounting plate is fixedly connected to the top of the six bases; the first mounting frame is fixedly connected to the upper left part of the first mounting plate; the first collection box is placed in the middle of the upper side of the first mounting frame; the second collection box and the third collection box are placed on the upper right part of the first mounting plate, and the second collection box is located to the left of the third collection box. The present invention realizes the dredging of the pipe openings by setting a number of dredging balls arranged in a ring shape, and all the cutting debris stuck in the openings are pushed out and separated at one time, replacing the subsequent manual processing and improving the processing efficiency.

[0004] However, when existing laser cutting machines are cutting hard and brittle materials, due to the influence of various factors, the materials may explode, causing material debris to splash around, and the material debris can easily cause harm to surrounding workers, posing certain safety hazards. At the same time, the explosion of hard and brittle materials will cause the loss of processed raw materials, thereby further increasing the production cost of laser cutting operations. Summary of the invention

[0007] Through the above technical scheme, the material to be cut is first placed on the material rack, and the mobile mechanical rack is driven to move on the base guide rail through the operating console, and the laser cutting machine body is moved on the mobile mechanical rack, so that the laser cutting machine body cuts the material according to the cutting requirements, and then the finished material and scraps are taken out, which is conducive to improving the convenience and accuracy of laser cutting operations, and the automated cutting operation further improves the production and processing efficiency.

[0011] Through the above technical scheme, the smoke detector is used to monitor the cutting smoke during the cutting operation. When a large amount of cutting smoke is detected, the smoke dust processor is controlled to perform smoke removal operation, thereby completing the smoke-free cutting operation and preventing the cutting waste gas from floating in the air and entering the respiratory tract of the staff, affecting the health of the operator's respiratory system, which is beneficial to improving the environmental protection performance of the laser cutting machine and optimizing the working environment of the laser cutting operation.

When the hard and brittle material explodes, the protective plate is used to block the flying fragments, which is beneficial to improve the safety of the laser cutting machine. When it is found that the degree of wear of the protective plate is too high, the bolts are turned outward to make the bolts away from the fixings and the connecting rod, which is convenient for separating the fixings and taking out the worn protective plate, and then the new protective plate is inserted into the connecting rod and the connecting base, and the fixings are aligned with the connecting rod and inserted into the upper end of the protective plate, and the connecting rod and the fixings are re-fixed with bolts, which is beneficial to improve the convenience of replacing the protective plate and maintain the anti-explosion performance of the laser cutting machine.

[0020] Compared with the related art, the laser cutting machine with anti-explosion function of hard and brittle materials provided by the present invention has the following beneficial effects: The present invention provides a laser cutting mechanism, a material preheating mechanism, an anti-explosion structure and a protective plate disassembly and assembly mechanism. When hard and brittle materials need to be cut, after the hard and brittle materials are placed, the temperature control module is first controlled by the operation console to start working, so that the heating wire and the heating tube heat the heat conducting plate, thereby completing the preheating of the hard and brittle materials above. At the same time, the temperature sensor is used to detect the hard and brittle materials to ensure that the surface temperature of the hard and brittle materials is moderate, thereby avoiding that the temperature difference between the cutting point and the surrounding material temperature is too large during laser cutting, preventing the hard and brittle materials from exploding due to excessive temperature difference, which is beneficial to reducing the probability of hard and brittle materials exploding during laser cutting, while reducing material loss and improving production efficiency. After the material is preheated, the cutting operation starts, and the connecting rod is driven by the electric telescopic rod. And the connecting base moves upward, so that the protective plate forms a protection around the workbench, and the protective plate is made of transparent acrylic plate to avoid affecting the observation of the material cutting process. When hard and brittle materials explode, the protective plate is used to block the flying fragments to avoid the material debris from causing harm to the surrounding workers, which is beneficial to improving the safety of the laser cutting machine. When the degree of wear of the protective plate is too high, the bolts are turned outward to make the bolts away from the fixings and the connecting rod, which is convenient for separating the fixings and taking out the worn protective plate, and then the new protective plate is inserted into the connecting rod and the connecting base, and the fixings are aligned with the connecting rod and inserted into the upper end of the protective plate, and the connecting rod and the fixings are re-fixed with bolts, which is beneficial to improving the convenience of replacing the protective plate and maintaining the anti-explosion performance of the laser cutting machine.
