Description

Technical Field

[0001] This utility model relates to the field of cutting and punching technology, and in particular to a laser heating cutting and punching machine. Background Technology

[0002] In modern manufacturing, the demand for precise cutting and punching of materials is increasing. Especially when processing special materials such as prepreg (PP), traditional machining methods often fall short of the requirements for precision, efficiency, and material properties. For example, patent CN202210639256.1 proposes a laser-heated cutting machine and its cutting method. This equipment utilizes a laser emitter and a cutting tool for preheating and final cutting operations, effectively achieving longitudinal and transverse cutting of prepreg materials. This method not only improves cutting accuracy but also reduces the area of ​​thermal damage, ensuring material quality.

[0003] However, with the diversification of industrial production demands for PP material processing, the shortcomings of existing technical solutions have gradually become apparent. Specifically, the technical solution in CN202210639256.1 mainly focuses on the cutting function and does not address drilling for PP materials. This means that in practical applications, when cutting and drilling operations need to be completed on the same machine, additional specialized equipment or manual tools must be used for secondary processing, significantly reducing production efficiency, increasing costs, and potentially leading to a decrease in processing accuracy due to multiple clamping operations.

[0029] like Figures 1-5 As shown in the figure, this utility model embodiment provides a laser heating cutting and punching machine.

[0030] A laser-heated cutting and punching machine includes a machine base 1, a longitudinal cutting mechanism 2, a punching mechanism 3, and a transverse cutting mechanism 4. A roller conveying mechanism 5 is mounted on the machine base 1. The longitudinal cutting mechanism 2, the punching mechanism 3, and the transverse cutting mechanism 4 are sequentially arranged from front to back around the roller conveying mechanism 5. The longitudinal cutting mechanism 2 includes a first crossbar 6, a first laser heating device 7, and a first cutter 8. Both ends of the first crossbar 6 are connected to the machine base 1. The first laser heating device 7 and the first cutter 8 are mounted on the first crossbar 6. The punching mechanism 3 includes a second crossbar 9 and several punching devices 10. Both ends of the second crossbar 9 are connected to the machine base 1. The punching devices 10 are mounted on the second crossbar 9. The transverse cutting mechanism 4 includes a third crossbar 11, a second laser heating device 12, and a second cutter 13. Both ends of the third crossbar 11 are connected to the machine base 1. The second laser heating device 12 and the second cutter 13 are mounted on the third crossbar 11.

[0031] This invention integrates cutting and punching functions into a single device, avoiding the problems of multiple clamping operations and the use of multiple devices required in traditional processes, thus greatly improving production efficiency and reducing operation time and costs. By employing a first laser heating device 7 and a second laser heating device 12 to preheat the material, the stability and consistency of the material during the cutting process are ensured, effectively preventing quality problems caused by localized overheating or uneven cooling. This equipment is not only suitable for prepreg materials but can also process many other types of materials, demonstrating strong adaptability and flexibility.

[0032] This embodiment describes a laser heating cutting and punching machine. A buffer mechanism 14 is provided between the longitudinal cutting mechanism 2 and the punching mechanism 3. The buffer mechanism 14 includes two first lifting drive cylinders 15 and a floating roller 17. Each output end of the first lifting drive cylinder is equipped with a bracket 18. Both ends of the floating roller 17 are rotatably connected to the bracket 18. It is understood that when the roller transmission mechanism 5 is continuously working, the longitudinal cutting mechanism 2 can cut along with the moving PP material. However, when the punching mechanism 3 and the transverse cutting mechanism 4 are working, the PP material must remain relatively stationary. This embodiment, by providing the buffer mechanism 14, allows the roller transmission mechanism 5 to continue working while the punching mechanism 3 and the transverse cutting mechanism 4 are operating. The PP material cut by the longitudinal cutting mechanism 2 can be carried on the bottom of the floating roller 17 and moved by the first lifting drive cylinders 15, making the PP material in the punching mechanism 3 and the transverse cutting mechanism 4 relatively stationary, facilitating punching and transverse cutting of the PP material. The above configuration eliminates the need to stop the roller conveyor mechanism 5 during punching and cross-cutting, allowing it to operate continuously and greatly improving work efficiency.

[0033] It is understood that the buffer mechanism 14 includes a transition plate 16, the two ends of which are respectively connected to the top of the two first lifting drive cylinders 15.

The second fixed frame 20 is located at the edge of the machine base 1. Both the first fixed frame 19 and the second fixed frame 20 are equipped with the punching device 10. Specifically, the second fixed frame 20 can punch holes at the edge of PP material, and the punching device 10 ensures the stability and accuracy of the drilling operation.

[0035] It is understandable that the first fixing frame 19, the second fixing frame 20, and the drilling device 10 can be assembled according to the actual needs of the product, and the positions of the first fixing frame 19 and the second fixing frame 20 and the number of drilling devices 10 can be adjusted.

The electric spindle 22 is mounted on the fastening block 26. A slider 27 is provided on the inner side of the fastening block 26, and the slider 27 is slidably connected to the guide rail 24. Specifically, the drilling device 10 achieves precise vertical movement through the first linear drive mechanism 23 and the guide rail 24. The electric spindle 22 is mounted on the fastening block 26 and slidably connected to the guide rail 24 through the slider 27, ensuring the stability and accuracy of the tool during drilling and improving drilling quality.

[0037] In this embodiment, a laser heating cutting and punching machine is described. A second linear drive mechanism 28 is mounted on the second fixed frame 20.

Specifically, the second linear drive mechanism 28 on the second fixed frame 20 enables the punching device 10 to move laterally. Through the connection of its output end to the connecting plate 21, the punching device 10 can be positioned and operated over a wider range, expanding the application scope of the equipment.

[0038] This embodiment describes a laser heating cutting and punching machine. The second cutter 13 includes an upper cutter holder 29, a lower cutter holder 30, an upper cutter 31, and a lower cutter 32. Second lifting drive cylinders 33 are installed on the inner sides of both ends of the machine base 1. The two ends of the upper cutter holder 29 are connected to the output ends of the two second lifting drive cylinders 33, respectively. The two ends of the lower cutter holder 30 are connected to the inner sides of both ends of the machine base 1, respectively. The upper cutter 31 is located at the bottom of the upper cutter holder 29, and the lower cutter 32 is located at the top of the lower cutter holder 30. The upper cutter 31 and the lower cutter 32 are correspondingly arranged. Specifically, the second cutter 13 adopts an upper and lower cutter holder and cutter design, and the lifting of the upper cutter holder 29 is controlled by the second lifting drive cylinders 33, ensuring close cooperation between the upper and lower cutters during transverse cutting, ensuring a flat and smooth cutting surface, and improving cutting quality.

The output end of the rotary drive mechanism 38 is connected to the active rollers 36, and the two ends of the transmission rollers 37 are rotatably connected to the inner sides of the two ends of the machine base 1, respectively.
