Description

Technical Field

[0001] This utility model relates to the field of fiber laser cutting machine technology, specifically to a fiber laser cutting machine suitable for cutting irregularly shaped metal parts. Background Technology

[0002] Fiber laser cutting machines can be used for cutting metal materials, especially for cutting irregularly shaped parts. When cutting irregularly shaped parts, the edges of the sheet metal are fixed by a clamping mechanism to maintain the stability of the sheet metal during the cutting process. However, after the irregularly shaped part is cut, it loses the overall support of the sheet metal and is prone to displacement or tilting due to its own stress or slight external forces. If the moving irregularly shaped part accidentally comes into contact with the cutting laser, it will be damaged, affecting the cutting accuracy and leading to an increased scrap rate.

[0003] Therefore, we propose a fiber laser cutting machine suitable for cutting irregularly shaped metal parts. Utility Model Content

[0004] This invention addresses the problem that irregularly shaped parts, after being cut, are prone to displacement or tipping due to their own stress or slight external forces because they lose the overall support of the sheet metal. Furthermore, if the moving irregularly shaped parts accidentally come into contact with the cutting laser, they will be damaged, affecting cutting accuracy and leading to an increased scrap rate. The invention provides a fiber laser cutting machine suitable for cutting irregularly shaped metal parts.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A fiber laser cutting machine suitable for cutting irregularly shaped metal parts includes a machine body. A processing area is centrally located at the upper end of the machine body, and a transparent protective cover is hydraulically hinged to the upper back side of the processing area. A dual-axis laser cutting head is mounted on the upper end of the processing area of ​​the machine body. A plate fixing frame is installed at the bottom of the processing area at the upper end of the machine body. A square groove is formed at the center of the processing area at the upper end of the machine body, and two hydraulic telescopic cylinders are embedded at the bottom of the square groove. A hollow multi-hole socket is fixedly connected to the upper end, and the upper end of the hollow multi-hole socket is flush with the bottom of the upper processing area of ​​the cutting machine body. The hollow multi-hole socket has multiple distributed insertion holes arranged in a rectangular pattern. Multiple airtight rod sleeves are inserted at the upper end of the distributed insertion holes corresponding to the center positions of multiple irregular parts to be cut. A pneumatic piston rod is inserted at the upper end of the airtight rod sleeve, and a fixed suction cup is fixedly connected to the upper end of the pneumatic piston rod. A reset ejection spring is fixedly sleeved on the outer wall of the pneumatic piston rod corresponding to the bottom of the fixed suction cup and the upper end of the airtight rod sleeve.

[0007] Furthermore, the upper processing area of ​​the cutting machine body is symmetrically and fixedly connected with side insertion slide rails on both sides, and the side insertion slide rails on both sides have strip slots on the inward side, and the plate fixing bottom frame is inserted into the strip slots on both sides of the side insertion slide rails.

[0008] Furthermore, the upper ends of both sides of the plate fixing base frame are fixedly connected with side threaded rods, and the upper ends of the side threaded rods are movably sleeved with plate pressure plates. The upper ends of the side threaded rods are connected with pressure plate fixing nuts corresponding to the upper side threads of the plate pressure plates.

[0009] Furthermore, the two sides of the side threaded rod are cut into a flat shaft shape, and the plate pressure plate has a through hole that matches the side threaded rod.

[0010] Furthermore, a vacuum cleaner is embedded in the bottom center of the cutting machine body, and the output end of the vacuum cleaner is connected to the bottom center of the hollow multi-hole socket through a telescopic corrugated hose.

[0011] Furthermore, a limiting protrusion is fixedly connected to the upper end of the outer wall of the airtight rod sleeve, and an external thread is opened on the outer wall of the airtight rod sleeve corresponding to the bottom of the limiting protrusion. An internal thread matching the external thread at the upper end of the airtight rod sleeve is opened on the inner wall of the distributed insertion hole.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In the cutting process, the irregularly shaped parts are stably fixed and will not be displaced due to their own stress or slight external force. The fixed position of the irregularly shaped parts effectively avoids accidental contact with the cutting laser, thereby ensuring the continuity and accuracy of the cutting process, reducing the scrap rate and improving production efficiency.

[0014] 2. This utility model enables the rapid positioning and stable sliding of the plate fixing frame on the upper part of the cutting machine body through the side-mounted sliding rail. When it is necessary to change or adjust the position of the plate, simply push the plate fixing frame along the side-mounted sliding rail. The operation is simple and the positioning is accurate. By using multiple plate fixing frames in rotation, the efficiency and flexibility of the cutting operation are effectively improved.

[0015] 3. This utility model achieves effective clamping and fixing of the plate edge through the combined use of the side threaded rod, plate pressure plate, and pressure plate fixing nut. When placing the plate, simply place it on the plate fixing base frame, then adjust the position of the plate pressure plate so that it presses against the edge of the plate, and finally tighten the pressure plate fixing nut to firmly fix the plate to the cutting machine body, preventing the plate from shifting due to vibration or cutting force during the cutting process, and further ensuring the cutting accuracy.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0022] Please see Figure 1 - Figure 4 This utility model provides a fiber laser cutting machine suitable for cutting irregularly shaped metal parts, including a cutting machine body 1. A processing area is located at the center of the upper end of the cutting machine body 1, and a transparent protective cover 2 is fixedly connected to the upper back side of the processing area via a hydraulic hinge. A dual-axis laser cutting head 3 is located at the upper end of the processing area of ​​the cutting machine body 1. A plate fixing frame 5 is installed at the bottom of the processing area at the upper end of the cutting machine body 1. A square groove is formed at the center of the processing area at the upper end of the cutting machine body 1, and two hydraulic telescopic cylinders 6 are embedded at the bottom of the square groove. The upper ends of the two hydraulic telescopic cylinders 6 are fixed... A hollow multi-hole socket 7 is fixedly connected, and the upper end of the hollow multi-hole socket 7 is flush with the bottom of the upper processing area of ​​the cutting machine body 1. The hollow multi-hole socket 7 has multiple distributed insertion holes 8 arranged in a rectangular shape. Multiple airtight rod sleeves 9 are inserted at the upper end of the distributed insertion holes 8 corresponding to the center position of multiple irregular parts to be cut. A pneumatic piston rod 10 is inserted at the upper end of the airtight rod sleeve 9, and a fixed suction cup 11 is fixedly connected to the upper end of the pneumatic piston rod 10. A reset ejection spring 12 is fixedly sleeved on the outer wall of the pneumatic piston rod 10 corresponding to the bottom of the fixed suction cup 11 and the upper end of the airtight rod sleeve 9.

[0023] In use, first place the irregularly shaped part to be cut on the plate fixing frame 5. According to the shape and position of the irregularly shaped part, insert the airtight rod sleeve 9 into the corresponding distributed insertion hole 8, ensuring that the position of the airtight rod sleeve 9 corresponds to the center position of the irregularly shaped part. Then, activate the hydraulic telescopic cylinder 6 to push the hollow multi-hole socket 7 upward, and the fixing suction cup 11 contacts the bottom of the irregularly shaped part. Then continue to push the pneumatic piston rod 10 downward inside the airtight rod sleeve 9, squeezing out the air inside the airtight rod sleeve 9, and the reset ejector spring 12 is compressed and stores elastic potential energy. Once the fixed suction cup 11 is tightly attached to the irregular part, the hydraulic telescopic cylinder 6 is driven to retract again. The pneumatic piston rod 10 is pulled out under the action of the hydraulic telescopic cylinder 6, generating negative pressure in the airtight sleeve 9. This allows the fixed suction cup 11 to adsorb and fix the irregular part area corresponding to the cut material. The fixed suction cup 11 is also fixed by the return spring force of the return spring 12, maintaining a fixed length. During the cutting process, the transparent protective cover 2 is closed, and the dual-axis laser cutting head 3 is started. The irregular part is cut according to the preset cutting path. The cut irregular part is fixed by the fixed suction cup 11. Therefore, during the cutting process, because the irregular part is stably fixed, it will not be displaced due to its own stress or slight external force. The fixed position of the irregular part effectively avoids accidental contact with the cutting laser, thereby ensuring the continuity and accuracy of the cutting process, reducing the scrap rate, and improving production efficiency.

[0024] In this embodiment, preferably, the bottom sides of the upper processing area of ​​the cutting machine body 1 are symmetrically fixedly connected with side insertion slide rails 4, and the side insertion slide rails 4 on both sides have strip slots on the inward side. The two sides of the plate fixing frame 5 are correspondingly inserted into the strip slots on both sides of the side insertion slide rails 4. The side insertion slide rails 4 can realize the quick positioning and stable sliding of the plate fixing frame 5 on the upper part of the cutting machine body 1. When it is necessary to change or adjust the position of the plate, it is only necessary to push the plate fixing frame 5 along the side insertion slide rails 4. The operation is simple and the positioning is accurate. By using multiple plate fixing frames 5 interchangeably, the efficiency and flexibility of the cutting operation are effectively improved.

[0025] In this embodiment, preferably, side threaded rods 13 are fixedly connected to the upper ends of both sides of the plate fixing base frame 5, and the upper ends of the side threaded rods 13 are movably sleeved with plate pressure plates 14. A pressure plate fixing nut 15 is threadedly connected to the upper end of the side threaded rods 13 corresponding to the upper side of the plate pressure plates 14. Through the coordinated use of the side threaded rods 13, plate pressure plates 14, and pressure plate fixing nuts 15, effective pressing and fixing of the plate edge is achieved. When placing the plate, simply place it on the plate fixing base frame 5, adjust the position of the plate pressure plates 14 so that they press against the plate edge, and finally tighten the pressure plate fixing nuts 15 to firmly fix the plate to the cutting machine body 1, preventing the plate from shifting due to vibration or cutting force during the cutting process, further ensuring cutting accuracy.

[0026] In this embodiment, preferably, the side threaded rod 13 is cut into a flat shaft shape on both sides, and the plate pressure plate 14 is provided with a through hole that matches the side threaded rod 13. By setting the side threaded rod 13 to be cut into a flat shaft shape on both sides and providing a matching through hole on the plate pressure plate 14, this design allows the plate pressure plate 14 to move up and down along the side threaded rod 13, thereby more stably fixing the plate pressure plate in the required position, ensuring the reliability of the plate edge fixing, effectively avoiding the problem of plate displacement caused by the pressure plate loosening, and further improving the stability and cutting accuracy of the cutting process.

[0027] In this embodiment, preferably, a vacuum cleaner 16 is embedded in the center of the bottom of the cutting machine body 1, and the output end of the vacuum cleaner 16 is connected to the center of the bottom of the hollow multi-hole socket 7 through a telescopic corrugated hose 17. Through the vacuum cleaner 16 and the telescopic corrugated hose 17, the vacuum cleaner 16 can be activated in real time during the cutting process. The telescopic corrugated hose 17 generates negative pressure within the hollow multi-hole socket 7, thereby sucking in and collecting metal dust and debris generated in the cutting area through the empty distributed insertion holes 8. This not only effectively avoids pollution of the cutting environment and equipment by dust and debris, reducing the difficulty and intensity of subsequent cleaning work, but also prevents dust and debris from interfering with the cutting process, such as adhering to the laser cutting head and affecting cutting accuracy, or interfering with the adsorption effect of the fixed suction cup 11 on irregularly shaped parts, thus further ensuring the smooth progress and quality of the cutting operation. Moreover, the vacuum cleaner 16 is embedded in the center of the bottom of the cutting machine body 1, without occupying additional space, making the entire equipment structure more compact and reasonable.

[0028] In this embodiment, preferably, a limiting protrusion ring is fixedly connected to the upper end of the outer wall of the airtight rod sleeve 9, and an external thread is formed on the outer wall of the airtight rod sleeve 9 corresponding to the bottom of the limiting protrusion ring. An internal thread matching the external thread at the upper end of the airtight rod sleeve 9 is formed on the inner wall of the distributed insertion hole 8. Through the cooperation of the airtight rod sleeve 9, the limiting protrusion ring, the external thread, and the internal thread, when the airtight rod sleeve 9 is inserted into the distributed insertion hole 8, the external thread and the internal thread engage, allowing the airtight rod sleeve 9 to be securely installed in the distributed insertion hole 8. Simultaneously, the limiting protrusion ring acts as a limit, providing positioning for the airtight rod sleeve 9 and ensuring the accuracy and stability of the installation. This design not only facilitates the installation and disassembly of the airtight rod sleeve 9, making maintenance and replacement easier, but also ensures the sealing between the airtight rod sleeve 9 and the distributed insertion hole 8, effectively preventing gas or dust generated during cutting from leaking from the connection point, further improving the performance and effectiveness of the cutting machine.
